Hereinafter, an embodiment of a bathing care system using the care chair of the present invention will be described with reference to the drawings.

FIG. 1 is a side view of the bathing care system, and FIG. 2 is a top view of FIG. 1. As shown in FIG. 1 and FIG. 2, the bathing care system is a system for caring for a care recipient while bathing, and comprises: a care chair 100 for the care recipient to sit on; and a guide rail unit 200, which is installed on the bathtub 8 and is used to guide the chair unit of the care chair 100 located in the bathroom W to the bathtub 8. Hereinafter, the care chair 100 will be described first, and then the guide rail unit 200 and its use method will be described. In addition, in order to facilitate the description, the description will be made in accordance with the directions shown in FIG. 1 to FIG. 3.

<1. Nursing Chair> As shown in FIG. 1 and FIG. 2 , the nursing chair 100 of this embodiment includes: a chair unit 1 for seating a user such as a person being cared for; a main body 2 for supporting the chair unit 1; and a base 3 for movably supporting the main body 2. Each component is described in detail below.

<1-1. Chair unit> First, the chair unit will be described with reference to FIG3. FIG3 is a three-dimensional view showing a support body and a backrest of a chair. As shown in FIG1 and FIG2, the chair unit 1 of this embodiment comprises: a support body 11, which is formed in an L-shape when viewed from the side; a chair 12, which can move on the support body 11; and a fixing mechanism 13, which is used to fix the chair 12 on the support body 11. The support body 11 is formed by connecting a first portion 111 extending in a substantially horizontal direction and a second portion 112 extending substantially upward from the rear end of the first portion 111.

As shown in FIG1 , the second portion 112 has a plate-shaped second portion body 113. The second portion body 113 is slightly bent in the middle portion in the up-down direction so as to protrude rearward. Furthermore, a gear (not shown in the figure) extending in the up-down direction is fixed on the back of the second portion body 113, and a small gear (not shown in the figure) exposed from the front surface of the main body 2 engages with the gear. The small gear is driven to rotate in the forward and reverse directions by a motor (not shown in the figure) built into the main body 2. Furthermore, a pair of first guide rails (not shown in the figure) extending in the up-down direction are provided on the back of the second portion body 113, and a roller (not shown in the figure) provided on the main body 2 is rotatably embedded in the first guide rails. Thereby, the second portion 112 can move up and down relative to the main body 2. Furthermore, when the motor of the main body 2 is driven, the second portion 112 moves up and down relative to the main body 2 together with the first portion 111. That is, the chair unit 1 is configured to move up and down relative to the main body 2.

On the other hand, as shown in Fig. 3, a pair of second rails 114 extending in the vertical direction are provided on both sides of the upper portion of the front surface of the second portion body 113. The second rails 114 are formed into an L-shaped cross section, and as described later, a first roller 125 provided on the chair 12 is embedded between the second portion body 113 and the second rails 114.

The first part 111 includes: a plate-like first part body 115; and a pair of third rails 116, which are provided on both sides of the upper surface of the first part body 115 and extend in the front-rear direction. The third rails 116 are formed in an L-shaped cross section, and as described later, the second roller 126 provided on the chair 12 is embedded between the first part body 115 and the third rails 116. In addition, three recesses (fixing parts) 117a to 117c are formed in the pair of third rails 116 at specific intervals in the front-rear direction. In the recesses 117a to 117c, as described later, the protrusions 138 of the fixing mechanism 13 are freely embedded in the recesses 117a to 117c. Here, for convenience of explanation, the recesses arranged from the front to the rear are sequentially referred to as the first recess 117a, the second recess 117b, and the third recess 117c.

Next, the chair 12 is described. As shown in FIG. 1 , the chair 12 includes a seat 121 extending in the front-rear direction, and a backrest 122 connected to the rear end of the seat 121 and extending generally upward, and formed in an L-shape when viewed from the side. A seat cushion 123 is mounted on the upper surface of the seat 121, and a backrest cushion 124 is mounted on the front surface of the backrest 122. The backrest cushion 124 is provided over the substantially entire length of the backrest 122 in the up-down direction, and is provided in a manner that, in the initial state, it extends beyond the backrest 122 and covers the front surface of the second portion 112.

As shown in FIG3 , a first roller 125 having a rotation axis extending in the horizontal direction (left-right direction) is provided at the upper end of the backrest portion 122, and the first roller 125 is embedded in the second guide rail 114 of the second portion 112 as described above. Therefore, the backrest portion 122 can move in the vertical direction along the second guide rail 114. In addition, the backrest portion 122 can swing with the first roller 125 as a fulcrum.

A second roller 126 having a rotating shaft extending in the horizontal direction is provided at the lower end of the backrest portion 122, and as described above, the second roller 126 is embedded in the third guide rail 116 of the first portion 111. Therefore, the lower end of the backrest portion 122 can move along the third guide rail 116 in the front-rear direction.

Since the seat 121 and the backrest 122 are formed as one body, for example, if the seat 121 is pulled forward, the lower end of the backrest 122 moves forward along the second portion 112. Accordingly, the backrest 122 swings forward with the first roller 125 as a fulcrum and moves downward. Thus, as the seat 121 moves forward, for example, as shown in FIG. 4 and FIG. 5, the backrest 122 tilts, and the seat 121 tilts with the front end facing upward. Thus, the entire chair 12 tilts on the support 11.

Next, the fixing mechanism 13 will be described with reference to FIG. 6A and FIG. 6B. FIG. 6A and FIG. 6B are side views showing the relationship between a portion of the support and the fixing mechanism. As shown in FIG. 6A, the fixing mechanism 13 has a first connecting member 131, a second connecting member 132, and a third connecting member 133 which are mounted on the lower surface of the seat 121 and arranged from the front side to the rear side. The first connecting member 131 is rotatably fixed by fixing its middle portion to the first shaft member 134 near the front end of the lower surface of the seat 121. The first shaft member 134 is a shaft member extending in the horizontal direction (left-right direction), and the second to fourth shaft members 135 to 137 described later also extend in the horizontal direction in the same manner. Furthermore, an operating handle 139 is installed at the front end of the first connecting member 131. Therefore, as shown in FIG. 6B , if the operating handle 139 is lifted upward, the rear end of the first connecting member 131 rotates downward. Furthermore, the rear end of the first connecting member 131 and the front end of the second connecting member 132 are rotatably connected to each other via the second shaft member 135. Furthermore, the rear end of the second connecting member 132 and the front end of the third connecting member 133 are rotatably connected to each other via the third shaft member 136.

The third connecting member 133 is bent in a manner that the front end thereof protrudes upward, and a fourth shaft member 137 is installed at the bent portion, and the fourth shaft member is fixed to the lower surface of the seat portion 121. Therefore, as shown in FIG. 6B , for example, if the front end of the third connecting member 133 is pushed backward and rotated downward, the rear end of the third connecting member 133 rotates upward. In addition, a protrusion 138 extending in the horizontal direction is installed at the rear end of the third connecting member 133, and the protrusion 138 is embedded in each of the recesses 117a to 117c of each of the third guide rails 116.

The fixing mechanism 13 constructed as described above operates as follows. As shown in FIG. 1 and FIG. 6A , if the protrusion 138 is embedded in the third recess 117 c in the initial state, the seat 121 is fixed in a manner that does not move on the first portion 111. From this state, as shown in FIG. 6B , if the operating handle 139 is lifted upward, the rear end of the first connecting member 131 rotates downward, and the second connecting member 132 is pushed backward. Furthermore, if the front end of the third connecting member 133 is pushed backward as the second connecting member 132 moves backward, the third connecting member 133 rotates around the fourth shaft member 137, and the rear end rotates upward. As a result, the protrusion 138 is separated from the third recess 117c, and the seat 121 becomes movable on the first portion 111. In this state, if the operating handle 139 is pulled forward, the seat 121 moves forward, and the entire chair tilts accordingly.

Furthermore, for example, when the protrusion 138 is disposed on the first recess 117a, if the operating handle 139 is pushed downward, the first to third connecting members 131 to 133 move in the opposite direction to the above, and the rear end of the third connecting member 133 rotates downward around the fourth shaft member 137, and the protrusion 138 is embedded in the first recess 117a. As a result, as shown in FIG. 5, the chair 12 is maintained in the most inclined state. In addition, FIG. 4 shows the state where the protrusion 138 is embedded in the second recess 117b.

<1-2. Main body> Next, the main body 2 will be described. As shown in FIG1 , the main body 2 includes: a rectangular parallelepiped housing 21, and a motor (not shown) housed in the housing 21. The motor is used to rotate the pinion as described above. The front surface of the housing 21 is inclined in a manner toward the front as it moves downward. In addition, a guide roller (not shown) is arranged on the front surface of the housing 21, and the guide roller is embedded in the first guide rail of the chair unit 1 described above. Thereby, the chair unit 1 can move up and down on the front side of the housing 21. In addition, since the front surface of the housing 21 is inclined as described above, the chair unit 1 is also constructed in a manner to move up and down along the inclination. For example, if the chair unit 1 is moved downward relative to the shell 21, it is moved slightly toward the front.

As will be described later, when the care receiver takes a bath, the chair unit 1 and the main body 2 are separated from the care chair 100 and moved toward the bathtub 8 .

<1-3. Base> Next, the base 3 will be described. The base 3 includes: a base 31 provided with a plurality of wheels 351 and 352; a first guide rail member 32 supporting the main body 2; and a support portion 33 extending upward from the base 31 to support the first guide rail member 32.

The base 31 has a pair of rod-shaped support members 311 extending in the front-rear direction, and a front wheel 351 and a rear wheel 352 are respectively installed on the lower side of the front and rear ends of each support member 311. The two support members 311 are arranged in parallel with a specific interval in the left-right direction, and the front end sides are connected by the first connecting member 312. On the other hand, the two support members 311 are connected near the middle of the front-rear direction by the second connecting member (not shown), and the above-mentioned support part 33 extends upward from the second connecting member to support the first guide member 32 from the bottom.

The first rail member 32 has a rail extending in the left-right direction, and the lower end surface of the housing 21 is movably fitted into the rail. Thus, the housing 21 can move in the left-right direction along the first rail member 32. When the housing 21 is located on the first rail member 32, its position can be locked. Furthermore, as described later, the first rail member 32 is provided at substantially the same height as the second rail member 9 provided on the upper surface of the bathtub 8.

<2. Guide rail unit of bathtub> Next, the guide rail unit 200 of the bathtub is described. First, the bathtub 8 is described. As shown in FIG. 2 , the bathtub 8 has a first wall portion 81 and a second wall portion 82 extending in parallel in the front-rear direction, and a third wall portion 83 and a fourth wall portion 84 extending in parallel in the left-right direction, and is formed into a rectangular shape when viewed from above. The first wall portion 81 is arranged on the left side (bathroom W side), and the second wall portion 82 is arranged on the right side, which extend in the long side direction of the bathtub 8. On the other hand, the third wall portion 83 is arranged on the front side, and the fourth wall portion 84 is arranged on the rear side, which extend in the short side direction of the bathtub 8.

The guide rail unit 200 includes a first fixture 71 disposed along the upper surface of the first wall portion 81, and a second fixture 72 disposed along the upper surface of the second wall portion 82. A clamping member (not shown) for clamping each wall portion 81, 82 is installed below the fixtures 71, 72, and each fixture 71, 72 is fixed to each wall portion 81, 82 by the clamping member.

The upper surfaces of the two fixtures 71, 72 are formed flat, and a second rail member 9 extending in the left-right direction is installed in a manner spanning the fixtures 71, 72. A rail is provided on the upper surface of the second rail member 9, and the shell 21 of the main body 2 of the above-mentioned chair unit can slide.

That is, the second rail member 9 and the first rail member 32 of the nursing chair 100 are located at substantially the same height, so that when the left end of the second rail member 9 contacts the right end of the first rail member 32, the housing 21 of the main body 2 can slide over the first rail member 32 and the second rail member 9. In addition, the left end of the second rail member 9 and the right end of the first rail member 32 can be locked. Furthermore, the housing 21 supported by the second rail member 9 can be locked on the second rail member 9 in a manner that does not move.

<3. Method of using the bathing care system> Next, the method of using the bathing care system constructed as above is also described with reference to Figures 7 to 9. Here, the action of moving the chair 12 of the care chair 100 arranged in the bathroom W into the bathtub 8 so that the person being cared for sitting on the chair 12 can be immersed in the bathtub 8 is described.

First, the chair unit 1 is lowered relative to the main body 2 so that the person being cared for sits on the chair 12. Next, the fixing mechanism 13 is operated to tilt the chair 12, and then, as shown in FIG7 , the chair unit 1 is raised to a position higher than the first wall portion 81. In FIG7 , the protrusion 138 is embedded in the first recess 117a. That is, the chair 12 is tilted the most. However, as shown in FIG4 , the protrusion 138 may also be embedded in the second recess 117b. Furthermore, the right end of the first rail member 32 and the left end of the second rail member 9 are connected in front and behind.

Next, as shown in Fig. 8, the main body 2 is slid from the first rail member 32 toward the second rail member 9. In this way, if the chair unit 1 is located above the bathtub 8 together with the main body 2, the main body 2 is locked in this position in a manner that does not slide.

Next, the motor of the main body 2 is driven, as shown in FIG9 , so that the chair unit 1 is lowered into the bathtub 8. In this way, the person being cared for can enter the bathtub 8 while remaining seated on the chair 12 and soak in the bath water. After the bath is finished, the chair unit 1 is raised in the opposite direction. If the chair unit 1 rises to a position above the upper surface of the bathtub 8, the sliding lock of the main body 2 is released, and the main body 2 is slid toward the W side of the bathroom. Furthermore, if the main body 2 moves onto the first guide member 32, it is locked. Thereafter, after the chair 1 is lowered, the lock of the second guide member 9 and the first guide member 32 is released, and the care chair 100 moves together with the person being cared for.

<4. Features> The following effects can be obtained according to the nursing chair of this embodiment.

(1) Since the chair 12 is arranged in front of the support body 11 formed in an L-shape when viewed from the side, and the chair 12 is tilted, even if the chair 12 is tilted greatly, it does not move further backward to the support body 11. Therefore, the head of the care receiver sitting on the chair 12 does not fall further backward to the support body 11. Therefore, the anxiety of the care receiver can be suppressed.

(2) Since the chair 12 does not move further behind the support 11, there is no need for a movement area behind the support 11 for tilting the chair 12. Therefore, the main body 2 can be brought close to the fourth wall 84 of the bathtub 8, and the bathtub 8 can be used spaciously. In addition, a movement space for the caregiver can be ensured behind the support 11.

(3) Since the chair 12 is tilted by the seat 121 moving forward and the backrest 122 moving downward, the force required for tilting can be reduced. In addition, when the chair 12 is tilted, a large ineffective space between the support 11 and the chair 12 can be prevented from being formed. Therefore, the bathtub 8 can be used spaciously. In addition, since the position of the caregiver sitting higher due to the tilt of the chair 12 can be prevented, the caregiver's anxiety can also be suppressed.

(4) The chair 12 is tilted in a well-balanced manner by the seat 121 moving forward and the backrest 122 moving downward. That is, since the entire chair is not tilted in a lifted manner as in the previous example, falling can be prevented. Furthermore, since the force acting on the support 11 or the main body 2 that receives the chair 12 is dispersed, the force acting on the support 11 etc. can be suppressed. As a result, damage to the care chair 100 can be prevented.

(5) The first portion 111 of the support body 11 extends in a substantially horizontal direction, but may be slightly inclined. For example, if it is inclined downward as it moves forward, when the chair 12 is tilted, that is, when the seat 121 is moved forward, the weight of the person being cared for can also assist in the movement, thereby reducing the burden on the caregiver who operates the operating handle 139. On the other hand, when the seat 121 is moved backward, since the force of the self-weight is used to return the seat 121, no large force is required.

(6) Since the operating handle 139 is disposed in front of the seat 121, the chair 12 can be tilted from the side of the seated caregiver. Therefore, when operating the operating handle 139, the caregiver can operate at a position consistent with the caregiver's line of sight, thereby suppressing the caregiver's anxiety.

<5. Variations> The above has been described with respect to the implementation forms of the present invention, but the present invention is not limited to the above implementation forms, and various modifications can be made as long as they do not deviate from the main purpose. For example, the following modifications can be made. In addition, any one of the following variations can be adopted, or multiple aspects can be combined without exception.

<5-1> The structure of the fixing mechanism 13 for fixing the tilted state of the chair 12 is not particularly limited, and can be various. That is, if the chair 12 can be tilted manually, its structure is not particularly limited. In addition, in order to fix the tilted position, the protrusion 138 is embedded in the recess 117, but even if it is a mechanism other than this, as long as the tilted position can be fixed.

<5-2> In the above-mentioned embodiment, the chair 12 is tilted by installing rollers 125 and 126 at the upper and lower ends of the backrest of the chair 12, and moving the rollers 125 and 126 along the guide rails 114 and 116 of the second portion 112 and the first portion 111 of the support body 11. However, the position of installing the rollers 125 and 126 is not particularly limited. As long as the chair 12 is configured in front of the support body 11, the seat 121 moves forward and the backrest 122 descends to tilt. For example, the backrest 122 may be configured to be bent near the middle, and the rollers may be provided at the bent portion.

<5-3> In the above-mentioned embodiment, the chair 12 is tilted manually, but it can also be tilted electrically.

<5-4> The mechanism for moving the support 11 up and down relative to the main body is not particularly limited, and may be a mechanism other than a gear or pinion. Furthermore, although the main body 2 is configured to slide relative to the base 3, this configuration is not essential, and the main body 2 may be simply fixed on the base 3 so that the support 11 can move up and down relative to the main body 2.

<5-5> The structure of the base 3 is not particularly limited, and it may not have wheels. In addition, it may be moved by a mechanism other than wheels.
