The wheelchair part 200 includes a chair bottom member 210 and a wheelchair base part 250.

The chair bottom member 210 is a substantially long rectangular plate-shaped member that supports the body of the person being cared for. The substantially long rectangle and plate shape referred to here are the same as the shape of the bottom member 110 of the bed body. In addition, during use, the chair bottom member 210 may also support the care recipient via a cushioning member (not shown). In this embodiment, the chair bottom member 210, like the bed body bottom member 110, also includes five plate-shaped members arranged in the longitudinal direction (the back bottom member 210a, the waist bottom member 210b, the knee bottom member 210c, The sole member 210d and the sole member 210e), by connecting two adjacent members of these members in a manner that can be arbitrarily rotated around a common axis, they are configured to be able to bend in the longitudinal direction of the chair bottom member 210 Fold stretch.

The wheelchair base part 250 is a frame structure composed of a plurality of rods, shafts, etc., supports the chair bottom member 210, and is further equipped with an electric actuator for operating and locking the connection mechanism, or air pressure or hydraulic pressure The cylinder and so on. Thereby, even in a state separated from the bed body 100 as shown in FIG. 2, the chair bottom member 210 can be deformed into a predetermined bent shape, and the predetermined shape can be maintained and supported. In addition, it can replace an electric actuator and include a mechanism that can be locked in a predetermined state. The arrows M21 to M23 in FIG. 2 show examples of the bending direction of the chair bottom member 210 caused by this bending and stretching of the wheelchair part 200. The chair bottom member 210 is bent in this way, and can be changed from the stretched shape used to support the caregiver who is lying in bed to the back cushion, seat surface, foot support, etc., which are used as a wheelchair for the caregiver. Chair shape. In addition, the wheelchair base part 250 may be further able to maintain and support the chair bottom member 210 in an intermediate shape between the stretched shape and the chair shape.

In addition, the wheelchair unit 200 further includes a controller (not shown) for controlling the actions of these actuators. Thereby, the caregiver can easily transform the wheelchair unit 200 from the flat posture to the chair posture.

In addition, the wheelchair base part 250 is provided with wheels 230a and 230b for making the wheelchair part 200 movable. In addition, the wheels 230a and 230b are part of the wheels provided in the wheelchair base part 250, and further include wheels 230c and 230d (hereinafter, the wheels 230a to 230d are also collectively referred to as wheels 230). The wheels 230c and 230d are shown in other drawings referenced later.

In addition, the wheelchair portion 200 further includes armrests 290L and armrests 290R (hereinafter also referred to as armrests 290), and extends in the x-axis direction at a position that encloses the waist bottom member 210b and the knee bottom member 210c in the z-axis direction when viewed from above. The armrests 290L and the armrests 290R are both located at the side of the seat surface of the wheelchair part 200. In this embodiment, the position from the waist bottom member 210b of the chair bottom member 210 to the knee bottom member 210c in a plan view has a position along the A long strip shape extending in the long side direction.

The armrests 290 respectively include an armrest top 290a and an armrest cover 290b. However, in FIG. 2, most of the armrest 290L is hidden, and only a small part of the armrest top 290a of the armrest 290L is displayed.

The armrest 290 can move up and down (in the direction of the y-axis shown in the figure). Figure 2 shows the state where the armrest 290 is at the lowest position. For example, when the wheelchair part 200 is in a state of being integrated with the bed body part 100, for example, in order to form a bed surface, the armrest top 290a is lowered to a height that does not interfere with the bed body bottom member 110 and the chair bottom member 210 side by side in the longitudinal direction. . When the wheelchair part 200 is separated from the bed body part 100, move the armrest 290 from this position upward as indicated by the arrow M24U, and raise the top surface of the armrest top 290a to a predetermined height, such as sitting in the wheelchair part 200 The height near the elbow of the person being cared for is fixed. The armrest 290 will be described later.

As with the aforementioned outer shape of the wheelchair part 200, it is substantially symmetrical with respect to a plane parallel to the xy plane passing through the center of the z-axis direction.

[1-4. Outline of the combined state of the bed main body and the wheelchair] When the bed main body 100 and the wheelchair 200 are in a combined state, as shown in Figure 1, one side of the bed main body bottom member 110 along the longitudinal direction It opposes substantially parallel to one side of the chair bottom member 210 along the longitudinal direction. At this time, the bed body part 100 and the wheelchair part 200, more specifically, the top surface of the bed body bottom member 110 and the top surface of the chair bottom member 210 form a flush bed surface. In addition, the back sole member 110a and the back sole member 210a are juxtaposed, the waist sole member 110b and the waist sole member 210b are juxtaposed, the knee sole member 110c and the knee sole member 210c are juxtaposed, the foot sole member 110d and the sole member 210d are juxtaposed, and the sole member 110e It is juxtaposed with the sole member 210e.

Here, the bed 10 separated from the combined state shown in FIG. 1 to the separated state shown in FIG. 2 is viewed from the care recipient lying on the bed in an appropriate posture, and the chair bottom member 210 is located on the bed body bottom member 110 On the right. Therefore, in order to transfer the cared person to the wheelchair unit 200, the carer moves the cared person from the bed-ridden state to the right hand direction of the cared person.

Furthermore, the bed 10 of this embodiment can also be used in a state in which the bed 10 is moved from the bed-ridden state to the left hand direction of the cared person in order to transfer the cared person to the wheelchair unit 200 as shown in FIG. 3. Fig. 3 is a perspective view of the bed body part 100 and the wheelchair part 200 prepared for the assembly of this use mode, viewed from the same direction as Figs. 1 and 2.

Comparing Figure 3 and Figure 2, the state shown in Figure 3 is different from the direction of the chair bottom member 210 and the wheels 230 and armrests 290 visible in front of the wheelchair base part 250. It is known that the entire wheelchair part 200 is from The state shown in Figure 2 is rotated 180 degrees in the horizontal direction (around the y axis). On the other hand, although the orientation of the bed base 150 in the bed body 100 is not changed, the bed body bottom member 110 is rotated by 180 degrees in the horizontal direction from the state shown in FIG. 2. Therefore, from the state shown in FIG. 3, the bed 10 in which the bed body part 100 and the wheelchair part 200 are integrated, maintains the aforementioned juxtaposition of the members of the bed body bottom member 110 and the members of the chair bottom member 210. On the other hand, the left and right positions of the bed body bottom member 110 and the chair bottom member 210 are exchanged from the state shown in FIG. 2. In the bed 10 in this integrated state, the caregiver moves the care recipient from the bed rest state to the left hand direction of the care recipient, and transfers from the bed body 100 to the wheelchair 200.

In this way, the bed body part 100 and the wheelchair part 200 of the bed 10 have a structure that can be selectively combined in the following combined state: one side of the bed body bottom member 110 along the longitudinal direction and the chair bottom member 210 along the length One side of the side direction is substantially parallel to each other to form a combined state of a flush bed surface (hereinafter also referred to as the first combined state); the other side of the bed body bottom member 110 along the longitudinal direction and the chair bottom member 210 The other side along the longitudinal direction is substantially parallel to each other to form a combined state of a flush bed surface (hereinafter also referred to as the second combined state). If connected with the drawings, Figures 2 and 3 can also be said to show that one side shows the bed body part 100 and the wheelchair part 200 ready to become the first combined state, and the other shows that the second part can become the second. The bed body part 100 and the wheelchair part 200 are prepared in a combined state.

In addition, in the bed 10 of this embodiment, in any of the first combined state and the second combined state, the bed body bottom member 110 and the chair bottom member 210 can be bent and stretched to provide support such as the above-mentioned back lifting. The function of the person. In the next item, the structure of the bed body 100 that can still provide these functions by exchanging the left and right positions of the bed body bottom member 110 and the chair bottom member 210 in this way will be described.

[2. Detailed structure of the bed main body] Fig. 4 is an exploded perspective view of the bed main body 100 in the assembled state shown in Fig. 2, and Fig. 5 is an exploded perspective view of the bed main body 100 in the assembled state shown in Fig. 3. Figs. 4 and 5 are views of the bed main body 100 viewed from the same direction as Figs. 1 to 3. If connected to each of the above-mentioned combined states, Figs. 4 and 5 can also be said to show the disassembled state of the bed main body 100 in which the bed main body 100 and the wheelchair section 200 are assembled in such a way that they can become the above-mentioned first combined state. The other side shows the disassembled state of the bed main body 100 assembled in such a way that it can be in the above-mentioned second combined state. In addition, the arrow of the one-dot chain line included in FIGS. 4 and 5 refers to the approximate installation positions of the components for making the bed body 100 from the disassembled state to the assembled state. The details will be described in the following description of each component of the bed body 100. In addition, in order to explain the arrangement of the assembled state of the constituent elements, etc., refer to FIG. 2 or FIG.

The bed body 100 includes a central support member 120b in addition to the upper body support member 120a, the knee support member 120c, and the foot support member 120d. The central supporting member 120b is also supported by the bed base portion 150 and is one of the supporting members 120 supporting the bottom member 110 of the bed body. These supporting members 120 can be disassembled, and the upper body supporting member 120a, the central supporting member 120b, the knee supporting member 120c, and the foot supporting member 120d are arranged and assembled in the order described above along the longitudinal direction of the bottom member 110 of the bed body. However, in FIGS. 4 and 5, the central support member 120b rotates 180 degrees to the bed base 150 in the horizontal direction, and the upper body support member 120a, the knee support member 120c, and the foot support member 120d are respectively mounted to the center support member 120b The location corresponds.

The central support member 120b of this embodiment is a structure formed by connecting a plurality of rods, shafts, etc., directly or via an upper body support member 120a described later to support the back bottom member 110a, and a knee support member 120c described later to support the knee bottom member 110c and the sole member 110d. In addition, when the bed body 100 and the wheelchair 200 are in a combined state, the central support member 120b further supports the back bottom member 210a via the upper body support member 120a, and supports the knee bottom member 210c and the foot bottom member 210d via the knee support member 120c . In addition, as seen by comparing FIG. 4 and FIG. 5, in the assembled state used in the first combined state and the assembled state used in the second combined state, the installation position of the central support member 120b is the same (arrow A1).

In addition, the central support member 120b includes an actuator 140a (refer to FIG. 4) and an actuator 140b (refer to FIG. 5).

The actuator 140a, for example, is connected to or operated as a part of one of the connecting mechanisms of the support member 120, and the upper body support member 120a moves the bed body bottom member 110 and the chair bottom member 210 to The respective long sides are bent and stretched. For example, the bending in the direction indicated by the arrow M11 in FIG. 1 is a part of the bending and stretching action. That is, the actuator 140a is a mechanism for providing a back lifting function on one end side in the x-axis direction. The actuator 140a of this embodiment is an example of the first bending and stretching mechanism.

The actuator 140b, for example, is connected to or operated as a part of the other connection mechanism of the supporting member 120, and the knee supporting member 120c makes the bed body bottom member 110 and the chair bottom member 210 Bend and stretch in the direction of their respective long sides. For example, the bending in the direction indicated by the arrow M12 in FIG. 1 is a part of the bending and stretching action. That is, the actuator 140b is a mechanism for realizing the knee-lifting function on the side opposite to the side where the actuator 140a provides the back-lifting function in the x-axis direction. The actuator 140b of this embodiment is an example of the second bending and stretching mechanism.

The central support member 120b having such a structure moves symmetrically with respect to the horizontal center plane of the bed base 150 when the bed main body 100 and the wheelchair 200 are combined in the first combined state and when combined in the second combined state. As a result, the bed 10 is shown in Figures 2 and 3, even if the bottom member 110 of the bed body and the wheelchair portion 200 are rotated 180 degrees in the horizontal direction, they can still be used to actuate the cared person with functions such as raising the back The device is set in the correct orientation. In addition, in terms of the switching operation between the first combined state and the second combined state, the change of the complex and heavy central support member 120b including the actuator is only the rotation at the same installation position, so as to pursue Simplification of work and lightening of load. The central support member 120b of this embodiment is an example of a second support member.

In this embodiment, the upper body support member 120a is a long rod, and is attached to one end side (arrow A2) of the center support member 120b in the x-axis direction in the assembled state of the bed body 100 to support the back bottom member 110a. In addition, when the bed body part 100 and the wheelchair part 200 are in a combined state, the upper body support member 120a further supports the back bottom member 210a of the wheelchair part 200. The upper body supporting member 120a, on the bed base portion 150, is supported by the above-mentioned central supporting member 120b. When the bottom member 110 of the bed body is in a shape in which the bottom member 110 is stretched, the upper body support member 120a itself is also directly supported by the bed base 150 near both ends in the longitudinal direction (refer to FIGS. 2 and 3).

In addition, the position indicated by the arrow A2 is a movable part of the link mechanism operated by the actuator 140a, and the upper body support member 120a is moved up and down by the operation of the actuator 140a. The back lifting function of the bed 10 is realized by the upper body supporting member 120a supporting the back bottom member 110a and the back bottom member 210a and moving this up and down. The upper body support member 120a of this embodiment is an example of a first support member.

The knee support member 120c of this embodiment is a structure in which two parallel rods are connected by a hinge. In the assembled state of the bed body 100, the hinge shaft part is upward (the positive direction of the y-axis), and one rod is installed at the end of the central support member 120b in the x-axis direction opposite to the side where the upper body support member 120a is installed. Side (arrow A3), and the other rod is attached to one end in the x-axis direction of the foot support member 120d described later (arrow A4). Thereby, the knee support member 120c is positioned below the knee bottom member 110c and the sole member 110d to support these members, and the shaft portion of the hinge is positioned below the connecting portion of the knee bottom member 110c and the sole member 110d. In addition, when the bed body part 100 and the wheelchair part 200 are in a combined state, the knee support member 120c further supports the knee bottom member 210c and the foot bottom member 210d of the wheelchair part 200, and the shaft part of the hinge is also located on the knee bottom member 210c and the foot bottom member Below the connecting part of 210d. In addition, the knee supporting member 120c is indirectly supported by the central supporting member 120b and the foot supporting member 120d on the bed base 150.

The position indicated by the arrow A3 is the movable part of the link mechanism operated by the actuator 140b. By the operation of the actuator 140b and the sliding of the bed base 150 of the foot support member 120d in the x-axis direction, The hinge of the knee support member 120c is opened and closed. The knee raising function of the bed 10 is achieved by closing the hinge of the knee support member 120c, the shaft part of the rising hinge, connecting the connecting part of the knee bottom member 110c and the foot bottom member 110d, and the knee bottom member 210c and the sole of the foot The connecting part of the member 210d is pushed up. The knee support member 120c of this embodiment is an example of a part of the third support member.

The foot support member 120d of this embodiment is connected so that a plurality of rods form a substantially rectangular structure. In the assembled state of the bed body 100, it is located below the foot bottom member 110d and the foot bottom member 110e (arrow A5) and is supported by the bed base 150 (refer to Figures 2 and 3), supporting the foot bottom member 110d and the foot The bottom member 110e. The foot support member 120d of this embodiment is an example of another part of the third support member.

With these structures, the upper body support member 120a (first support member), the knee support member 120c and the foot support member 120d (third support member) are combined in the first integrated state of the bed body 100 and the wheelchair 200 When and when combined in the second combined state, it moves symmetrically with respect to the horizontal center plane of the bed base portion 150.

In addition, the bed body bottom member 110, after changing the positional relationship between the support member 120 and the bed base portion 150 as described above, is carried on the support member 120 in a direction that moves symmetrically with respect to the transverse center plane of the bed base portion 150 (arrow A6). ). Then, the wheelchair part 200 moves symmetrically with respect to the horizontal center plane of the bed base part 150, moves in parallel in the direction along the z-axis, and merges with the bed body part 100.

In this way, the left and right positions of the bed body bottom member 110 and the chair bottom member 210 are exchanged. Before and after the exchange, the positional relationship between the bed body bottom member 110 and the support member 120 is relative to the center plane of the bed body bottom member 110 in the x-axis direction. symmetry. In addition, in any of the combined states before and after the exchange, the movement of the connecting mechanism caused by the actions of the support member 120 and the actuator 140 is also similarly moved to the chair bottom member 210 by the upper body support member 120a and the knee support member 120c. transfer. That is, regardless of the left and right positional relationship between the bed body part 100 and the wheelchair part 200, functions such as raising the back of the care receiver are provided. In addition, for the operation for switching between the first combined state and the second combined state, it is a lighter first support member by making the object of position exchange for the bed base 150 not include an actuator. And the third support member, and the figure seeks to reduce the load.

[3. Effect] The bed 10 of this embodiment includes: a bed body part 100 having a substantially long rectangular plate-like shape, including a bed body bottom member 110 that can be bent and extended in the longitudinal direction, and a supporting bed body bottom member 110 of the bed base portion 150; and the wheelchair portion 200, which has a substantially long rectangular plate-like shape, and includes a chair bottom member 210 that can be bent and stretched in the longitudinal direction; the bed body portion 100 and the wheelchair portion 200 have the following features: Combined state selectively combined structure: In the first combined state, one side of the bed body bottom member 110 along the longitudinal direction is substantially parallel to the side of the chair bottom member 210 along the longitudinal direction to form a flush. The bed surface; the second combined state, the other side of the bed body bottom member 110 along the longitudinal direction and the other side of the chair bottom member 210 along the longitudinal direction are substantially parallel to each other to form a flush bed surface.

Thereby, for example, the manufacturer or supplier of the bed 10 can selectively exchange the left and right positions of the bed body part 100 and the wheelchair part 200 by using the bed 10 having the same constituent elements. In addition, when the user moves house or the like, the bed 10 also allows the user's moving destination to be unrestricted by the detachable direction of the wheelchair. In addition, due to the detachable direction of the wheelchair, the configuration of the bed 10 that generates the moving destination is not limited, and a replacement bed 10 must be purchased.

Specifically, for example, the bed body 100 further includes a first support member 120a, a second support member 120b, and third support members 120c and 120d that are sequentially arranged along the longitudinal direction of the bed body bottom member 110. The supporting member is supported by the bed base 150 and supports the bottom member 110 of the bed body; the second supporting member 120b is equipped with the first bending and stretching mechanism 140a, and in the first integrated state, the first supporting member 120a is in the first integrated state. 2 combined state The bed body bottom member 110 is bent and stretched along the longitudinal direction of the bed body bottom member 110 by the third support members 120c and 120d; when the bed body part 100 and the wheelchair part 200 are combined in the first combined state , And when combined in the second combined state, the second support member 120b, the bed body bottom member 110, and the wheelchair portion 200 move symmetrically with respect to the horizontal center plane of the bed base portion 150.

With this, for example, when the bed 10 formed by combining the bed body 100 and the wheelchair 200 has a back lifting function, when the left and right positions of the bed body 100 and the wheelchair 200 are exchanged, the back lifting function can be easily changed. The orientation of the first bending and stretching mechanism 140a.

In addition, the bed body part 100 may also include a first support member 120a, a second support member 120b, and third support members 120c and 120d arranged in order along the longitudinal direction of the bed body bottom member 110, etc. The support member is supported by the bed base portion 150 and supports the bed body bottom member 110; the second support member 120b is provided with: a first bending and stretching mechanism 140a. The first support member 120a makes the bed body bottom member 110 follow The bed body bottom member 110 is bent and stretched in the longitudinal direction; and the second bending and stretching mechanism 140b, through the third support members 120c and 120d, makes the bed body bottom member 110 along the long side direction of the bed body bottom member 110 Bending and stretching; when the bed body part 100 and the wheelchair part 200 are combined in the first combined state, and when combined in the second combined state, the second support member 120b, the first support member 120a, and the third support members 120c and 120d, It moves symmetrically with the wheelchair part 200 with respect to the horizontal center plane of the bed base part 150.

With this, for example, when the bed 10 has a back-lifting function and a knee-lifting function, the first bending and stretching mechanism 140a for the back-lifting function can be easily changed when the left and right positions of the bed body 100 and the wheelchair portion 200 are exchanged. , And the respective orientations of the second bending and stretching mechanism 140b for the knee lift function.

(Embodiment 2) [1. Overview] The configuration in which the left and right positions of the bed body and the wheelchair can be exchanged is not limited to the above configuration. The bed 1010 of the present embodiment includes a base part having a different configuration from that of the first embodiment, and includes a bed body part that can exchange left and right positions with the wheelchair part.

Fig. 6 is a perspective view showing the overall appearance of the bed 1010 of this embodiment. The appearance of the bed 1010 and the actions shown by the arrows M11 and M12 in the figure are the same as the appearance and actions of the bed 10 shown in FIG. 1. In addition, the wheelchair portion, bed body bottom member, and support member included in the bed 1010 are also the same as the wheelchair portion 200, bed body bottom member 110, and support member 120 of the first embodiment, so the description and support members of the first embodiment are also used. Figures 2 to 5 replace the descriptions and drawings about these components, and will not be repeated here. The appearance of the bed body part of the bed 1010 in the assembled state is basically the same as that of the bed body part 100 of the first embodiment, and the detailed structure of the bed base part is different from that of the bed base part 150. Hereinafter, the configuration of the bed base portion 1150 of the bed 1010 will be described.

[2. The structure of the bed base part] FIGS. 7A and 7B are plan views of the bed base part 1150 of the second embodiment.

The components of the bed base portion 1150 shown in FIGS. 7A and 7B are basically the same as those of the first embodiment. Here, the components that are not described using FIGS. 1 to 5 will be described. In addition, the bed base portion 1150 shown in FIGS. 7A and 7B assumes that the proper posture of the body of the care recipient is that when viewed from the center, the feet face the positive direction of the x-axis and the head faces the negative direction.

As shown in FIGS. 7A and 7B, the rectangular area A11 of a one-point chain line indicates the position of the central supporting member 120b of the bed base portion 1150, that is, the installation position of the central supporting member 120b (hereinafter referred to as the installation position A11 of the central supporting member 120b) ). In addition, in this embodiment, unlike the first embodiment, there is no bracket-like member for supporting the central support member 120b, and the central support member 120b is supported by the bed base portion 1150 in a manner different from that of the first embodiment. For example, the central support member 120b is provided with a hook (not shown), and the hook is attached to the rod constituting the bed base portion 1150 to be supported by the bed base portion 1150.

In addition, the rectangular area A21 of the one-point chain line is the position where the wheelchair base part 250 of the wheelchair part 200 that enters in the progress direction indicated by the arrow T2 and is in a state of being integrated with the bed body part 100 is fixed (hereinafter referred to as wheelchair The fixed position A21 of the part 200).

The bed base beam 170 is a columnar member extending in the longitudinal direction of the bed base portion 1150 (in the direction of the x-axis shown in the figure), and has a large size for supporting the combined bed 1010 and the person being cared for The rigidity used for the load is used to connect the head side and the foot side of the bed base 150. Therefore, in this embodiment, the bed base beam 170 is located in the installation position A11 in a plan view so as not to interfere with the wheelchair part 200.

The wheelchair stopper 175 is fixed to the bed base beam 170 and is a member extending from the installation position A11 of the central support member 120b to the fixed position A21 of the wheelchair part 200 when viewed from above. At the time when the bed body part 100 is separated, the wheelchair part 200 is in a state where the armrest 290 is lowered (refer to FIG. 6). If the wheelchair unit 200 on which the care recipient is seated moves in this state, there is a risk of the care recipient falling. In order to reduce this risk, if the wheelchair part 200 is moved in the direction of separating from the bed body part 100 (the direction of the arrow T1) while the armrest 290 is lowered, the lower end of the armrest 290 (in this example, the armrest 290L) will abut The recessed part of the U-shaped part (the part located in the fixed position A21) of the wheelchair stopper 175 can restrict the movement of the wheelchair part 200 so that it cannot be separated. If the armrest 290 is raised to the extent that the lower end part does not abut the wheelchair stopper 175, this restriction is released. The wheelchair part 200 can be moved and separated in a safe state where the armrest 290 prevents the person being cared for from falling.

In addition, although only one wheelchair fixing part 180 is seen in FIGS. 2 to 5, as shown in FIGS. 7A and 7B, the wheelchair part 200 is provided with wheelchair fixing parts at both ends of the fixing position A21 in the x-axis direction.

In the bed base portion 1150 shown in FIG. 7A and the bed base portion 1150 shown in FIG. 7B, the wheelchair fixing portion 180 and the bed base beam 170 are located in the short-side direction (along the view) when passing through the bed base portion 1150 The direction of the z-axis shown) is a symmetrical position on the plane parallel to the xy plane (the dashed line in Figs. 7A and 7B, hereinafter also referred to as the vertical center plane). Thereby, in the bed base part 1150, the attachment position A11 of the center support member 120b and the fixed position A21 of the wheelchair part 200 can be exchanged. In addition, the wheelchair fixing portion 180 and the bed base beam 170 are fixed to the bed base portion 1150 by, for example, screws, and are configured to be attachable and detachable.

That is, with this configuration, the fixed position of the wheelchair part 200 moves symmetrically with respect to the longitudinal center plane of the bed base part 1150. In addition, the central support member 120b (second support member) can be installed at a position that moves symmetrically with respect to the longitudinal center plane of the bed base portion 1150 and is supported by the bed base portion 1150. Thereby, the bed main body part 100 and the wheelchair part 200 can be selectively combined in the first combined state and the second combined state as described above. In addition, regarding the movement of the wheelchair part 200 in the first combined state and the second combined state, if compared with the first embodiment, the first embodiment relates to the symmetrical movement of the horizontal center plane of the bed base part 150, and this embodiment It is a symmetrical movement with respect to the longitudinal center plane of the bed base portion 1150.

In addition, the wheelchair fixing part 180 moves symmetrically with respect to the longitudinal center plane of the bed base part 1150 when the bed body part 100 and the wheelchair part 200 are combined in the first combined state and when combined in the second combined state. Thereby, when the bed body part 100 and the wheelchair part 200 are in either the first combined state and the second combined state, the accidental separation of the wheelchair part 200 is suppressed.

In addition, the position and extending direction of the wheelchair stopper 175 also change with the movement of the bed base beam 170. Thereby, when the bed body part 100 and the wheelchair part 200 are separated from any of the combined states, the wheelchair stopper 175 can still function as described above.

In addition, the above-mentioned change of the positions of the wheelchair fixing portion 180 and the bed base beam 170 is realized with the following configuration, for example. The above-mentioned bed base beam 170 and wheelchair fixing portion 180 are fixed to the bed base portion 1150 with screws. In this case, the bed base portion 1150 is provided with screw holes for fixing these components at a position symmetrical to the longitudinal center plane of the bed base portion 1150. Thereby, the arrangement of the bed base beam 170 and the wheelchair fixing portion 180 symmetrical to the longitudinal center plane of the bed base portion 1150 can be fixed.

In addition, the structure for fixing the wheelchair fixing portion 180 and the bed base beam 170 to the bed base portion 1150 is not limited to the type using screws. For example, the wheelchair fixing part 180 and the bed base beam 170 may be provided with brackets, and these brackets may be hooked to the rod of the bed base part 1150, and a stopper pin may be inserted.

In addition, regarding the supporting members 120 other than the central supporting member 120b, they move in accordance with the position of the central supporting member 120b. For example, in the case of FIG. 7A, the upper body support member 120a, the knee support member 120c, and the foot support member 120d are combined in the same manner as in FIG. In the case of FIG. 7B, the upper body support member 120a, the knee support member 120c, and the foot support member 120d are combined in the same manner as in FIG. In addition, the knee support member 120c is moved symmetrically with respect to the longitudinal center plane of the bed base portion 1150 (refer to FIGS. 2 to 5), and the hinge of the knee support member 120c is kept away from the edge of the bed, so that the person being cared for or the caregiver It is difficult for the fingers to enter under the bottom member 110 of the bed body from the periphery of the bed and be caught by the hinge.

In this way, the bed 1010 of the present embodiment is the same as the bed 10 of the first embodiment, and has a structure in which the left and right positions of the bed body part 100 and the wheelchair part 200 before delivery can be exchanged. In addition, the bed 1010 of this embodiment, after the start of use, for example, even in a place where there is no space for turning the bed 1010, the posture of the person being cared for (the position of the head and feet) can still be changed for movement. By the direction of the movement, the path of the wheelchair part 200 to be integrated with the bed body part 100 is changed.

In addition, the bed base beam 170, the wheelchair stopper 175, and the wheelchair fixing portion 180 described as components that move symmetrically with respect to the longitudinal center plane of the bed base portion 1150 in the above content are a series of examples. The bed base part 1150 may not have all of these constituent elements. In addition, in response to the design, for example, it is also considered that the bed base beam 170 and the wheelchair stopper 175 are initially symmetrical with respect to the longitudinal center plane of the bed base portion 1150. These constituent elements are not included in the moving object. In addition, the bed base portion 1150 may be further equipped with elements that move symmetrically by other constituent elements.

[3. Effect] In the bed 1010 of this embodiment, the bed body 100 includes a first support member 120a, a second support member 120b, and a third support member 120a, a second support member 120b, and a third Support members 120c and 120d, these support members are supported by the bed base portion 1150 and support the bed body bottom member 110; when the bed body portion 100 and the wheelchair portion 200 are combined in the first combined state, and in the second combined state When combined, the second support member 120b and the wheelchair portion 200 move symmetrically with respect to the longitudinal center plane of the bed base portion 1150.

Thereby, as with the bed 10 of the first embodiment, the left and right positions of the bed body 100 and the wheelchair 200 can be selectively exchanged by the bed 1010 of the same constituent element.

In addition, the bed body part 100 may further include a wheelchair fixing part 180 supported by the bed base part 1150 to fix the wheelchair part 200 when in the first combined state and in the second combined state; When the wheelchair portion 200 is combined in the first combined state and when combined in the second combined state, the wheelchair fixing portion 180 moves symmetrically with respect to the longitudinal center plane of the bed base portion 1150.

Thereby, the bed 1010 can function as a safety mechanism to prevent accidental separation of the wheelchair part 200 from the bed body part 100 even if the left and right positions of the bed body part and the wheelchair part are exchanged.

(Others) [1. Armrest] As described above, in the wheelchair unit 200, the armrest 290 includes an armrest top 290a and an armrest cover 290b. When the wheelchair part 200 is in a state of being separated from the bed body part 100, the armrest 290 is lifted up to a predetermined height for use. FIG. 8A is a perspective view of the wheelchair part 200 in a state where the armrest 290 is raised to a predetermined height, and FIG. 8B is a front view of the wheelchair part 200 in a state where the armrest 290 is raised to a predetermined height. When the wheelchair part 200 is integrated with the bed body part 100, the armrest 290 moves from the position shown in Figs. 8A and 8B to the downward direction indicated by the arrow M24D, and descends to a predetermined height, for example, in order to form a bed surface, and lower it so as not to interfere. Up to the height of the bed body bottom member 110 and the chair bottom member 210 arranged side by side in the longitudinal direction. In addition, the arrows M21 to M23 show examples of the bending direction of the chair bottom member 210 in the same manner as in FIGS. 2 and 3.

The top of the armrest 290a is held by the cared person standing up from the wheelchair part 200 or sitting down to the wheelchair part 200 in order to support the body and prevent the cared person sitting in the wheelchair part 200 from going to the side of the wheelchair part 200 (the z-axis in the figure) Direction) of the fall.

The armrest cover 290b has an outer side surface and an inner side surface extending along the longitudinal direction of the chair bottom member 210. As shown in FIGS. 8A and 8B, when the armrest 290 is in the position in use, a wall that encloses the seat surface (the waist bottom member 210b and the knee bottom member 210c) in the z-axis direction is formed below the armrest top 290a. Thereby, it is prevented that a part of the care recipient's body such as towels or a part of the care recipient's body, such as knees or thighs, protrude from the seat surface of the wheelchair part 200 beyond the top of the armrest 290a. For example, if a foot protruding to the outside from the side of the armrest 290 hits an obstacle in the route of the wheelchair part 200, it may cause injury to the person being cared for or the people around it. However, due to the person being cared for, the lower limbs cannot move freely and accidentally shift to the left and right. The armrest cover 290b functions as a safety mechanism for restricting the movement of these feet.

[2. Lines on the side] Furthermore, the outer surface of the side bar fixing member 190 of the bed main body 100 and the outer surface of the armrest cover 290b may be in the first combined state or the second integrated state between the bed main body 100 and the wheelchair portion 200. In the two-combined state, it is configured to form an integrated line extending in the longitudinal direction of the bed main body 100. Although this line is also displayed in the combined state of the bed body part 100 and the wheelchair part 200 shown in FIG. 1, the integration point is further explained using the example shown in FIG. 9.

FIG. 9 is a front view of the bed 10 in which the bed body part 100 and the wheelchair part 200 are integrated. The side rail fixing member 190 has an outer side surface extending along the longitudinal direction of the bed body 100. In this figure, the line L1 of the side bar holder 190a on the outer side, the line L2 of the armrest cover 290b on the outer side, and the line L3 of the side bar holder 190b on the outer side, are located along x as shown below The state on one imaginary straight line of the two arrows in the axial direction is an example of the above-mentioned "formation of an integrated line". More specifically, the lines L1 to L3 shown in this figure are recesses (grooves) provided on the outer side surfaces of the side rod holder 190 and the armrest cover 290b and extending along the same straight line.

With this line, for example, the caregiver can visually easily confirm whether or not the armrest 290 is stored in an appropriate position (height), and whether or not the combination of the bed body part 100 and the wheelchair part 200 is properly performed.

In addition, although FIG. 9 shows the lines L1 to L3 as grooves, the lines L1 to L3 are not limited to this aspect. The lines L1 to L3, for example, may also be convex portions extending along the same straight line, may be a line of a color that can be easily recognized by the naked eye, or may be a combination of concave portions or convex portions and colors. In addition, it may not be a line covering the entire length of the bed 10 as shown in FIG. 9. For example, in FIG. 9, it is also possible to have recesses only near the right half of L1 and the left end of L2, and near the left half of L3 and the right end of L2. The bed body part 100 and the wheelchair part 200 may be properly combined. In this case, make these recesses along the same straight line. In addition, the appearance of the thread may be different on the left and right sides of the bed 10. With this, when the bed body that can be integrated with the wheelchair is located in multiple places such as homes and nursing facilities, or wards, examination rooms, treatment rooms, etc., the left and right positional relationship between the wheelchair and the bed body can be easily grasped. In addition, these integrated lines can also be provided on the top surfaces of the top of the armrest 290a and the side rod fixing member 190. Thereby, the care receiver and the caregiver can easily confirm whether the combination of the bed body 100 and the wheelchair 200 is properly performed when viewed from above.

In addition, for each embodiment, various modifications considered by those skilled in the art in the technical field are implemented, or the constituent elements and functions of each embodiment are arbitrarily combined without departing from the scope of the present invention. A form realized with a part of these is also included in the present invention.

For example, the bed 10 may not have a knee-lifting function. That is, the function provided by the bending and stretching of the bed body bottom member 110 and the chair bottom member 210 is only to raise the back.

In this case, the support member 120 may not have the connecting mechanism for knee raising and the actuator 140b (the second bending and stretching mechanism). Among the support members 120, the upper body support member 120a (the first support member), the knee support member 120c, and the foot support member 120d (the third support member) may also be used for the bed body in the assembled state of the bed body 100 The horizontal center plane of the part 100 is symmetrical. For example, the first support member and the third support member are both non-movable structures in which the hinge of the knee support member 120c in the third support member described above is replaced with a rod. The following points are the same as the first embodiment: the central support member 120b (second support member), in the first combined state and the second combined state, moves symmetrically with respect to the horizontal center plane of the bed base portion 150 as the bed Supported by the base station 150. On the other hand, in the first bending and stretching mechanism of the central support member 120b, in the first combined state, the bed bottom member 110 is bent and extended to lift the back by the first supporting member. In addition, in the second combined state by The third supporting member causes the bed body bottom member 110 to bend and stretch to lift the back. That is, unlike the first embodiment, in this case, the positional relationship between the bed base portion 150 of the first support member and the third support member is not exchanged.

In addition, in this case, the bed body bottom member 110 may also be composed of two members: for example, a member corresponding to the back bottom member 110a and other members that are lifted up to lift the back. In this case, the bed body bottom member 110 is the same as in the first embodiment, and is supported by the support member 120 in a direction that moves symmetrically with respect to the horizontal center plane of the bed base portion 150. In addition, the bed main body bottom member 110 may also be composed of three members: a member corresponding to the back bottom member 110a at both ends in the longitudinal direction, and a member connecting these two members in between. In this case, in the positional relationship between the bed body bottom member 110 and the bed base portion 150, the first combined state and the second combined state may move symmetrically with respect to the horizontal center plane of the bed base portion 150 as It is supported by the supporting member 120, but there is no need for rotation. In addition, in the same manner as in the first embodiment, the bed body bottom member 110 including five members may be used.

In addition, when the bed body part 100 or the wheelchair part 200 has constituent elements other than the above, these constituent elements can also be changed in the first and second combined states of the bed body part 100 and the wheelchair part 200 as necessary. The position on the bed base 150 or the wheelchair base 250. For example, the mechanism including the actuators used to move the entire bed 10 up and down, the controllers and their wiring used to control the aforementioned actuators, the cables used to supply power to the actuators and charge the batteries, etc., are appropriately arranged in each A position that does not hinder the movement of movable components in the combined state, or a position that is easy to use by the person being cared for or caregivers.

[3. Effect] As described above, in the bed 10 and the bed 1010 of each of the above embodiments, the wheelchair portion 200 may also be provided with an armrest cover 290b, and the armrest cover 290b has an extension extending along the longitudinal direction of the chair bottom member 210 Outside.

In this way, it is possible to prevent the object held by the person being cared for or a part of the body from protruding or slipping off the seat surface of the wheelchair part 200. In this way, the interference of obstacles on the route of the wheelchair part 200 can be avoided.

In addition, the bed main body 100 may further include a side bar fixing member 190 having an outer side surface extending along the longitudinal direction of the bed main body, and the bed main body 100 and the wheelchair 200 are in the first or second combined state. At this time, the outer surface of the side rod fixing member 190 and the outer surface of the armrest cover 290b form an integrated line extending along the longitudinal direction of the bed body 100.

Thereby, it is possible to easily visually confirm whether the armrest 290 is stored in an appropriate position (height), and whether the combination of the bed body part 100 and the wheelchair part 200 is performed properly.
