Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a bed apparatus that can be used as a wheelchair by separating a part of a floorboard.

[0002]

[Prior Art]

 For example, wheelchairs are used to reduce the burden on caregivers when moving bedridden sick people or the elderly from bed to other locations. However, it is not easy to transfer a bedridden sick person or an elderly person from the bed to a wheelchair, and the caregiver may hurt their back when doing so.

Therefore, a bed device has been developed in which a part of the bed device can be divided and the part can be converted into a wheelchair. As such a conventional technique, a separable bed disclosed in Japanese Utility Model Laid-Open No. 2-23531 has been proposed. The bed shown in this publication is divided into a first side part, a central part and a second side part so that the bed part extends in the longitudinal direction, and the second side part is a first part and a second part. It is divided into two.

The above-mentioned central portion is movable, and has a configuration in which it can take any of two forms, that is, a form in which it is flatly extended under normal conditions and a form of a wheelchair. The first portion and the second portion of the second side portion are attached to one end sides of the pair of arms, respectively. The other ends of these arms are connected to the leg portions on the side of the first side by a universal joint so as to be rotatable in the vertical and horizontal directions.

In the bed state, the central portion is provided between the pair of side portions, and these are connected to each other to maintain the shape of the bed. When the central portion is used as a wheelchair, the first portion and the second portion of the second side portion are pivoted downward and also laterally pivoted to separate from each other. The frame of the central portion can be pulled out between the end portions of the respective portions while being passed through the upper surface side of the respective portions.

However, according to such a configuration, when separating the central portion, not only the second side portion is rotated downward, but also the first and second portions of the second side portion are separated from each other. You also have to rotate it to the left and right. In other words, while maintaining the state in which the second side portion is rotated downward, the first and second portions must be rotated in the direction of separating left and right, and the central portion must be pulled out while maintaining that state. .. Therefore, the operation for separating the central part from the bed or assembling the separated central part may be complicated and time-consuming.

Further, in order to make the central portion freely removable, the second side portion must be divided into two in a direction intersecting with the longitudinal direction. However, if the second side part is divided into two parts, the rigidity with respect to the load applied to the upper surface may decrease when the bed is used in a flat state.

Further, according to the configuration in which the first portion and the second portion of the second side portion are rotated in the left-right direction, the space for that must be secured in the front-back direction of the bed, It may be necessary to install a large bed.

[0009]

[Problems to be solved by the device]

 As described above, the conventional one may have poor operability when a part of the bed is separated or assembled, and the rigidity may be low when the bed is used in a flat state. ..

The present invention has been made in view of the above circumstances, and an object thereof is to easily operate when separating or assembling a part of a floor plate that serves as a vehicle chair, and yet to reduce rigidity. To provide bed equipment.

[0011]

Means for Solving the Problems In order to solve the above problems, the present invention relates to a bed apparatus in which a bed body is provided with a floor plate for a user to lay down, and the floor plate is arranged in the width direction of the bed body. On the other hand, the first side floorboard is divided into the first side floorboard, the second side floorboard and the central floorboard, and the first side floorboard located at one end in the width direction is horizontally held by the bed body and the other end side. The second side floor plate, which is located at, is rotatably provided in an upward direction from a horizontal state at substantially the same height as the first side floor plate with one end in the width direction of the bed main body as a fulcrum. The movable floor is horizontally held at almost the same height as the first and second side floor boards, and the central floor board can be converted from a horizontal state to a chair state on the truck. It is characterized by being.

[0012]

[Action]

 According to the above configuration, the central floor plate can be separated or assembled by simply rotating the second side floor plate upward, so that the operation is easy and the central floor plate can be freely inserted and removed. In addition, the first side floorboard and the second side floorboard are divided so that their rigidity is not reduced.

The other end of the arm 10 is inserted and fixed in the hollow connecting portion 17a formed in the connecting member 17.

The rotating body 15 and the connecting member 17 are urged in the rotating direction by the vine spring 21. That is, the arm 10 is rotated together with the connecting member 17 in a state in which no load is applied to the vine winding spring 21 and one end side is rotated upward as shown by a chain line in FIG. It is mounted and fixed on. Therefore, when the arm 10 is rotated from the raised position to the horizontal state, the coil spring 21 is elastically deformed, so that the restoring force of the coil spring 21 raises the arm 10. Rotation in the direction can be done easily with a light force.

A stopper pin 22 is accommodated in the end portion of the receiving member 4 of the end frame 2 as shown in FIG. 3A. The first stopper pin 22 is biased by a coil spring 23 in a direction projecting from a through hole 24 formed in the upper surface of the receiving member 4. A pipe 8b having a rectangular cross section is provided at an end of the second side floor plate 8, and an engaging hole 25 is formed in the pipe 8b. When the second side floor plate 8 is rotated to a horizontal state where it is joined to the receiving member 4, the first stopper pin 22 engages with the engagement hole 25. Thereby, the second side floor plate 8 is held by the bed body 1.

The central floor plate 9 is provided between the first side floor plate 7 and the second side floor plate 8 so as to be freely inserted and removed. That is, the central floor plate 9 is divided into first to third flat plates 26a to 26c, and the flat plates 26a to 26c are rotatably connected to each other. The second flat plate 26b located at the center is pivotally supported by the carriage 27 shown in FIGS. 4 and 5. That is, the carriage 27 connects a pair of side frames 28 bent in an inverted U shape at a predetermined interval by a plurality of connecting rods 29, and casters 30 are provided at the lower ends of the side frames 28, respectively, so that the side frames 28 can be freely moved. It can be driven. Rollers 31 and brackets 32 are provided on the upper sides of the pair of side frames 28, respectively. The second flat plate 26b is rotatably connected to the brackets 32, and the roller 31 is in rolling contact with the lower surface of the second flat plate 26a.

The height of the central floor plate 9 provided on the carriage 27 is set to be the same as that of the first and second side floor plates 7 and 8, and the length is a pair of ends of the bed body 1. The size is set so that it can be put in and taken out between the partial frames 2, and the width is set so that at least one user can lie down.

A mounting member 33 is installed on one end side of the upper side of the side frame 28. One end of a storage pipe 34 is pivotally attached to the mounting member 33. One end of a gas spring 35 is stored and held in the storage pipe 34. A rod 36 projects from the other end of the gas spring 35. A bracket 37 is attached to the tip of the rod 36. The bracket 37 is pivotally attached to the lower surface of the first flat plate 26a pivotally attached to one end of the second flat plate 26b. Further, as shown in FIG. 6, an intermediate portion of the operating lever 38 is pivotally attached to the bracket 37. One end of the operating lever 38 faces the operating pin 36 a protruding from the rod 36. Therefore, by rotating the operation lever 38 and pressing the operation pin 36a, the locked state of the rod 36 of the gas spring 35 can be released.

As shown in FIG. 4, one end of a first link 39 is attached to the side surface of the base end portion of the first flat plate 26a. The other end of the first link 39 extends toward the lower surface of the second flat plate 26b, and the other end thereof is pivotally attached to one end of a second link 41. The other end of the second link 41 is pivotally attached to a bracket 42 provided on the lower surface on the base end side of the third flat plate 26c pivotally attached to the other end side of the second flat plate 26b. ing.

The first flat plate 26a has an end portion provided with a holding member 43 projecting to the lower surface side, and the third flat plate 26c has an end portion provided with a footrest member 44 projecting to the upper surface side. There is.

When the rod 36 of the gas spring 35 is retracted, the first to third flat plates 26a to 26c are flat as shown by the solid line in FIG. When the operating lever 38 is operated to release the locked state of the rod 36 and urge it in the projecting direction, the first flat plate 26a rises up to a substantially vertical state as shown by the chain line in FIG. .. As the first flat plate 26a stands up, the third flat plate 26c rotates in the descending direction via the first link 39 and the second link 41. At this time, the second flat plate 26b inclines slightly toward the first flat plate 26a side with the point pivotally attached to the bracket 32 as a fulcrum. That is, in this state, the first flat plate 26a serves as a backrest, the second flat plate 26b serves as a seat plate, and the foot can be placed on the foot rest member 44 provided at the end of the third flat plate 26c. Converted into a chair that can.

At both ends of the pair of side frames 28 of the carriage 27, as shown in FIG. 5, support bodies 45 each made of a short pipe are attached. As shown by the chain line in FIG. 1, fence members 46 are detachably attached to the pair of first supports 45 of each side frame 28. These fence members 46 can be used as armrests when the central floorboard 9 is converted into a chair.

In addition, as shown in FIG. 1, the connecting member 3 of the bed body 1 is formed with a pair of insertion holes 47 opening to the upper surface, and further, one side of the second side floor plate 8 is provided. A pair of second supports 48, which are short tubes, are provided. The pair of insertion holes 47 and the second support 48 can be replaced with the pair of fence members 46 supported by the first support body 45 of the carriage 27 to be used as side fences. A trolley 49 for holding articles is detachably held on the lower surface side of the second flat plate 26a on the carriage 27 by using a connecting rod 29 connecting a pair of side frames 28.

Further, as shown in FIG. 2, a pair of second stopper pins 51 (only one is shown on the lower surface of one end of the second side floor plate 8 on the first side floor plate 7 side in the width direction). ) Is elastically biased in the protruding direction. The second stopper pin 51 allows the central floor plate 9 to move in the width direction of the truck 27 when the central floor plate 9 is placed together with the truck 27 between the first side floor plate 7 and the second side floor plate 8. It is adapted to engage with the pair of first supports 45 on one end side.

Beddings 52a to 52c such as mattresses and duvets shown by chain lines in FIG. 2 are placed and fixed on the upper surfaces of the first side floor plate 7, the second side floor plate 8 and the center side floor plate 9, respectively. ing.

In the bed apparatus having the above-described structure, as shown in FIG. 2, the carriage 27 is positioned inside the bed body 1, and the central floor plate 9 provided on the upper surface of the carriage 27 is attached to the first side floor plate 7 and the second floor plate 7. If it is located between the side floorboards 8, the plane formed by each floorboard can be used as the bed surface. Since the floor plates 7, 8 and 9 that form the bed surface are not divided in the middle part in the longitudinal direction, they exhibit greater rigidity with respect to the load applied to the bed surface than when they are divided. .. That is, it is possible to support the user in a stable bed-like state. The second side floor plate 8 engages with the first stopper pin 22 provided on the receiving member 4, and the carriage 27 engages with the second stopper pin 51 provided on the second side floor plate 2. Since they are fitted together, these engagements hold the second floor plate 8 and the central floor plate 9 without rattling, and the stability of the bed surface is good.

When the central floorboard 9 is separated from the bed apparatus to form a wheelchair, first, the patient who is lying on the bed is moved to the central floorboard 9. Usually, since the patient is lying down in the central part of the bed, there is almost no need to move the patient at that time, and it does not impose a heavy burden on the caregiver.

When the patient is moved onto the central floorboard 9, the second side floorboard 8 is rotated in the upward direction together with the arm 10 to the state shown by the chain line in FIG. At this time, since the restoring force of the vine winding spring 21 acts on the arm 10 in the rotation direction thereof, the second side floor plate 8 can be easily rotated and raised by a relatively light force. On the contrary, when the arm 10 is rotated in the descending direction, the arm 10 is rotated against the restoring force of the coil spring 21, so that the second side floor plate 8 is rapidly rotated by its own weight. Is prevented.

When the second side floor plate 8 is lifted, the central floor plate 9 is separated from the bed body 1 together with the carriage 27 as shown in FIG. Separation of the central floor plate 9 only requires pulling out the trolley 27 with the second side floor plate 8 raised, so that the separating operation does not impose a heavy burden on the caregiver. ..

After the central floor plate 9 is separated, the operating pin 36a provided at the tip of the rod 36 of the gas spring 35 is pressed by the operating lever 38 to release the locked state of the gas spring 35. As a result, the rod 36 is urged in the protruding direction, so that the first flat plate 26a of the central floor plate 9 of the carriage 27 moves up and the third flat plate 26c moves down, so that the central floor plate 9 moves. As shown by the chain line in Fig. 5, it is converted into a chair state. In other words, the patient is in a state of lying on the bed instead of sitting on a chair. Therefore, the caregiver can easily and freely move the patient by running the chair.

When the carriage 27 is returned to its original position, first, the operating pin 36a of the gas spring 35 is pressed to release the locked state, and the central floor plate 9 is erected while maintaining the released state. A certain first flat plate 26a is rotated in the fall direction. Since the second and third flat plates 26b and 26c are also interlocked with the rotation, the central floor plate 9 can be returned to a horizontal bed state.

Next, with the second side floor plate 8 being rotated in the ascending direction, the carriage 27 is run into the bed main body 1 and the central floor plate 9 thereof is moved to the first side floor plate 7. Side by side. Then, by rotating the second side floor plate 8 in the descending direction until it becomes horizontal, the central floor plate 9 can be returned to the bed state in which it cannot be separated from the bed body 1. Even when the central floor plate 9 is returned to its original position, the trolley 27 is simply moved while the second side floor plate 8 is being raised, so the work at that time is also easy.

[0036]

[Effect of the device]

 As described above, according to the present invention, the floorboard is divided into the first side floorboard, the second side floorboard and the central floorboard, and the first side floorboard is attached to the bed body, and the second side floorboard is attached. So that it can be rotated upward from a horizontal state with the first side floorboard side as a fulcrum, the central floorboard is provided on a freely movable carriage, and the second side floorboard is raised. So that they can be separated in the open state.

Therefore, according to such a configuration, the central floor plate can be separated or the original floor plate can be separated by simply moving the carriage in and out of the bed body with the second side floor plate raised. Because it can be returned, the work can be done easily and quickly. Further, since the central floor plate can be made separable without dividing the second lateral floor plate as in the conventional case, the rigidity of the second lateral floor plate can be prevented from being lowered. Further, since the second side floor plate is rotated upward, there is a case where it is not necessary to secure an extra space in the front-back direction of the bed body as in the conventional case.
