Summary of the Invention

Problems to be Solved by the Invention

[0005] The examples described in Patent Documents 1 and 2 involve a device that moves (slides) horizontally along a track (rail) installed in the upper part of a room. However, installing a track inside a house is not easy, both structurally and in terms of cost. Moving the device horizontally along the track and stopping it at the appropriate position requires a complex device configuration, and its operation becomes difficult, often becoming a burden for the family of the person being cared for.

[0006] The invention described in this application takes the above-mentioned problems into consideration and provides an assistance device that is simple in structure and easy to operate, which can appropriately assist elderly people, people with disabilities, and other persons requiring assistance when moving between a wheelchair and other living facilities, without the need to provide a track for horizontal movement. [Means for solving the problem]

[0007] The devised assistance device is an assistance device that supports the body of the person being assisted when moving between a wheelchair and other living facilities (referring to a toilet, bathtub, or bed, etc.) by a flexible support (including a support column or pipe, etc., described later) that is installed from the upper part of the room downwards. The invention is characterized in that a rotating support member is attached to the upper part of the interior so as to be able to rotate horizontally, and the upper part of the support member is attached to the rotating support member at an eccentric position away from the center of the horizontal rotation. An example of the assistive device devised is shown in Figures 1 and 2. Reference numeral 10 in the figures indicates a rotating support member, and the upper part of the support pipe 30 is attached at an eccentric position (see Figure 2) away from the pivot shaft 12 (center of rotation) of the rotating support member 10.

[0008] If the support device that supports the body of the person being assisted is attached to the rotating support member at an eccentric position as described above, the support device will move a predetermined distance horizontally when it rotates horizontally with the rotating support member, according to the amount of eccentricity, i.e., the distance from the center of rotation to the mounting position of the support device. The horizontal distance when moving between a wheelchair and living facilities such as a toilet (toilet seat), bathtub, or bed is at most 1 to 2 meters, so it is possible to achieve this movement even through movement based on the eccentricity during horizontal rotation as described above. In particular, when a person being assisted moves between a wheelchair and a toilet, etc., it is necessary to change the orientation of their body (rotate horizontally) and move their body position in the forward and backward directions, making the assistance device described above extremely suitable. That is, the device of this invention, which simultaneously achieves horizontal rotation and horizontal movement using a rotating support member and a support attached to its eccentric position, can provide appropriate support in accordance with the movement of the person being assisted. This is clearly more rational than conventional devices that move horizontally along a track using a means of transport and change orientation using another means of transport, and it can be said that it has the advantage of a simpler configuration because a track and means of transport are unnecessary, as well as being easy to operate.

[0009] In the assistance device of the above invention, The rotating support member can be locked for horizontal rotation at multiple angular positions. It is preferable that the horizontal rotation of the rotating support member is locked at each angular position, such as when the support device (for example, the front) is oriented to support the person being cared for when they enter the room in a wheelchair, and when it is oriented to support the person being cared for when they use the other living facilities. The orientation of a support device suitable for supporting a person being cared for when using living facilities refers to the orientation for supporting the person being cared for when sitting on or standing up from a toilet seat, for example, the orientation of Y shown in Figures 4, 5(a), and 5(b). On the other hand, the orientation of a support device suitable for supporting a person being cared for when entering a room in a wheelchair refers to the orientation for supporting the person being cared for when entering or leaving a toilet in a wheelchair, for example, the orientation of X1 in Figure 4, the orientation of X2 in Figure 5(a), or the orientation of X3 in Figure 5(b).

[0010] When a person requiring assistance enters (or leaves) a room in a wheelchair, or when using (or finishing using) a toilet or other living facilities, the person will stand up or sit down, and a support device is needed to support them to prevent them from stumbling and falling during this process. If the rotating support member rotates freely horizontally in such situations, the support device will also move unstably, making it difficult to firmly support the person requiring assistance. However, if the rotating support member is locked and does not rotate horizontally as described above, the person requiring assistance can be properly supported by the support device to prevent them from falling.

[0011] Or, furthermore, It is also preferable that the horizontal rotation of the above-mentioned rotating support member be configured to be lockable (rotation stopped) at 90° intervals, 45° intervals, or 30° intervals. Figure 2 shows an example in which the rotation support member 10 can be locked at 90° intervals, and Figures 4 and 5 show an example in which it can be locked at 45° intervals. In each figure, reference numeral 14 denotes a locking pin for locking, and when it protrudes and is inserted into the pin insertion hole 13 of the rotation drive device 11, the horizontal rotation of the rotation support member 10 is locked.

[0012] Depending on the person being assisted, for example, they may not be able to move and change direction quickly enough to get up from a wheelchair and sit on a toilet seat, and may have to stop their movement midway. If the horizontal rotation of the rotating support member can be locked in small increments as described above, it will be possible to properly support the person being assisted who has to stop their movement midway as described above.

[0013] Regarding the devised assistive device, The rotating support member may be attached to the ceiling of the room, or to the top of a support frame that stands independently on the floor of the room. Figures 1 to 4 show examples of the rotating support member 10 being attached to the ceiling portion 2. Figure 6 illustrates a support frame 50 that can stand independently on the floor surface of a room.

[0014] When a rotating support member is installed on the ceiling of a room such as a toilet, bathroom, or bedroom, it can appropriately support the person being cared for when moving between a wheelchair and the toilet, bathtub, bed, etc., using an assistance device. Alternatively, if a support frame is made to stand independently on the floor of a room such as a toilet, bathroom, or bedroom, and the rotating support member is attached to the top of it, the same level of support can be provided to the person being cared for without having to carry out construction work to install the rotating support member on the ceiling of that room.

[0015] The devised assistive device is, in particular, Preferably, the above-mentioned support device consists of two pipes made of fiber-reinforced resin, with the upper part of each pipe attached to the eccentric position of the rotating support member, and the lower part of each pipe connected to the left and right sides of a torso support device attached to the torso of the person being assisted. Suitable fiber-reinforced resin pipes include, for example, pipes made of carbon fiber reinforced resin (CFRP), glass fiber reinforced resin (GFRP), and aramid fiber reinforced resin. In the assistive device 1 illustrated in Figures 1 to 4, as described above, two fiber-reinforced resin pipes 30 are used as supports connected to the torso support 40. Furthermore, to allow the person being assisted to move horizontally, it is preferable that the torso support be positioned at an eccentric location away from the center of the horizontal rotation, as shown in Figure 4.

[0016] Fiber-reinforced resin pipes, used in fishing rods and golf clubs, are highly strong yet flexible, allowing them to follow the movements of the person being assisted while providing gentle rebound force. Therefore, in assistive devices using these pipes as support, when the person being assisted makes unstable movements such as swaying forward, backward, left, or right, the pipes flex to follow the person being assisted and apply an appropriate force to return them to their original position or posture. Therefore, the above-mentioned assistive devices do not need to be configured to fully support the weight of the person being assisted, but can be configured to assist or support the person being assisted in standing up or sitting down using their remaining abilities. By utilizing remaining abilities, the assistive devices can also exert an effect that encourages the person being assisted to maintain their physical strength and recover their physical functions through assistance. Since there are two of the above-mentioned pipes, and the ends of each pipe are connected to the above-mentioned torso support on the left and right sides of the person being assisted, the above-mentioned assistance device can easily return the posture of the person being assisted to its original position due to the repulsive force of the pipes, and can also exert force to reverse rotational movements around the center of the body.

[0017] In an assistive device that uses pipes as support members as described above, The upper part of each pipe is attached to the above-mentioned rotating support member in a constrained state such that it cannot be angularly displaced in at least one direction, and the angular range in which it can be displaced in the direction of angular displacement is limited. It is particularly preferable that the above-mentioned pipe has a telescopic structure (nesting type) that allows for length adjustment, and that a traction member (for example, a wire or other wire material or a flexible rod material) for lifting the body support is passed through the pipe. In the assisting device 1 illustrated in FIG. 1 and the like, the pipe is also attached in such a manner. The upper part of the pipe 30 in FIG. 1(b) cannot be angularly displaced in the left - right direction (the left - right of the assisted person) of the figure, but can be angularly displaced within a certain range (for example, ±45° centered on vertically downward) in the direction perpendicular to the drawing plane (the front - back direction of the assisted person). Further, a wire 33 is passed through the inside of the pipe 30, the body support 40 and the upper winder are connected by the wire 33, and the wire 33 is operated by an operating mechanism including a motor 23 and the like to pull the body support 40.

[0018] If the upper part of the pipe can be freely angularly displaced in all directions, it cannot properly support the movement of the assisted person in the front, back, left, and right directions. However, in a toilet, a bathroom, a bedroom, etc., it is normal for the assisted person to move in a specific direction (for example, when standing in the toilet, bending forward and backward or tilting the body). Therefore, it is suitable for supporting the assisted person that the base end of the pipe is attached in such a state that it cannot be angularly displaced in at least one direction (for example, left - right) as described above, and can be angularly displaced within a limited range in another direction (for example, front - back). Also, when the above pipe has a telescopic structure that can change its length and a towing member is passed through the pipe, it is possible to actively assist the up - and - down movement of the assisted person when standing or sitting. By operating to pull up the towing member (for example, winding up a wire), the body support can be pulled up (at that time the pipe shrinks telescopically), thereby exerting a force to make the assisted person stand. Also, by operating to gradually loosen and lower the towing member (for example, unwinding a wire. At that time the pipe extends telescopically), assistance can be provided for making the assisted person sit.

[0019] In the above - mentioned assisting device where the pipe can be angularly displaced within a certain range only in a specific direction, · It is preferable that the upper part of each of the above pipes is attached at an eccentric position that is 5 cm or more and 50 cm or less away from the center of the horizontal rotation in the above - mentioned rotary support member. In the example of Fig. 2, each pipe is located at a position approximately 15 cm (illustrated as d) away from the center of the horizontal rotation.

[0020] As described above, when the pipes as the supports can be angularly displaced within a certain range only in a specific direction, if the upper parts of those pipes are at an eccentric position approximately 5 to 50 cm away from the center of the horizontal rotation of the rotary support member, it can sufficiently follow the movement of the assisted person moving between the wheelchair and the living facilities (such as a toilet). The horizontal distance from the position of the wheelchair that has entered and stopped at the toilet or the like to the position of the toilet or the like is about 1 m. However, when combining the distance that can be horizontally moved based on the above-described amount of eccentricity and the distance that can be horizontally moved by the angular displacement of the pipe, it is possible to horizontally move the trunk support tool below the pipe by about 1 m. This is because of this.

Effect of the Invention

[0021] According to the assisting device of the invention, horizontal rotation and horizontal movement can be simultaneously realized by the rotary support member and the support attached to its eccentric position. Therefore, even without providing a track or the like for horizontal movement, the assisted person when moving between the wheelchair and other living facilities can be appropriately supported. Since means for horizontal movement are not required, the structure of the device becomes simple and the operation also becomes easy. If the rotary support member is attached to the upper part of the support frame that stands on the indoor floor surface, there is no need to perform construction work for attaching the rotary support member to the indoor ceiling portion, and the equipment cost becomes even lower. If the above-mentioned support is two pipes made of fiber-reinforced resin and the lower part of each pipe is connected to each side of the left and right of the trunk support tool worn on the trunk of the assisted person, when the assisted person makes an unstable movement such as staggering, the pipe can flexibly follow the assisted person, and can exert an appropriate force in the direction of returning to the original position and posture on the assisted person. Thereby, the assisting device can assist or support the assisted person to stand or sit using their remaining ability, and can also exert the effect of maintaining the physical strength or restoring the function of the assisted person.

Figure 1(b) is a detailed view of part b in Figure 1(a), i.e., the rotating support member, etc. Figure 1(c) is an explanatory diagram showing how the assistance device 1 supports the person being assisted A, who is supported by part c below in Figure 1(a), when the person leans to the side in the toilet. [Figure 2] Figures 2(a) to (e) show the horizontal rotation of the rotating support member 10 of the assistive device 1 in Figure 1, and the positions (side views) of the pipe (support) 30 and the body support 40, etc., when the rotating support member 10 is at the angular positions of (a), (c), and (e) are shown in (a'), (c'), and (e'). Note that (a) is a cross-sectional view of aa in (a'), and Figures (b) to (e) are similar. [Figure 3] This is a detailed view of part III in Figure 2(a'). [Figure 4] This diagram shows how an assistance device 1 installed in a toilet supports a person A being assisted as they move between a wheelchair W and a toilet C. Figure 4(a) is a side view, and Figure 4(b) is a top view. [Figure 5] Figures 5(a) and 5(b) are plan views showing the movement of the assistance device 1 in a toilet where the positional relationship between the entrance and the toilet bowl C is different from the example in Figure 4. [Figure 6] This is a front view (perspective view) of a support frame 50 that can stand independently on the floor of a room and to which a rotating support member can be attached to the top. [Best Mode for Carrying Out the Invention]

[0023] An example of the assistive device devised is shown in Figures 1 to 6. As shown in Figure 1(a), this assistance device 1 has a rotating support member 10 attached to a mounting plate 3 fixed to the ceiling portion 2, along with a rotating drive device 11 and a rotating pivot shaft 12. Below the rotating support member 10, there is an operating section 20 and two pipes (supports) 30, and a body support 40 is connected to the lower ends of these pipes 30. The rotating support member 10 can rotate horizontally with the rotating pivot shaft 12 as the center of rotation by the action of the rotating drive device 11. The pipes 30 function as supports to support the person being assisted A and are made of flexible carbon fiber reinforced polymer (CFRP). Each of the pipes 30 is made by connecting multiple pipes of different diameters so that it can be telescopically extended and retracted. The body support 40 for holding the person being assisted A is connected to the lower ends of these pipes 30. Person A receiving assistance is fitted with a torso support 40 near their chest, and the lower end 32 of the pipe 30 is detachably connected to the left and right sides of the back of the torso support 40 by buckles 41.

[0024] As shown in Figure 1(b), a wire 33 is passed through the inside of the pipe 30, and its lower end is tied to the lower end of the pipe 30. On the other hand, the upper part of the wire 33 is brought out from the upper end of the pipe 30 and wound around a winding machine installed in the operating unit 20. When the winding machine is rotated by the motor 23, the wire 33 is wound up and the body support 40 is pulled up, allowing the person being assisted A to stand, or the wire 33 is unwound and the position of the body support 40 is lowered, allowing the person being assisted A to sit.

[0025] A disc-shaped holder 31 is attached to the upper end of the pipe 30, having a hole at the bottom for inserting and holding the pipe, and a horizontal support shaft near the center. This holder 31 is supported by a pipe support 22 fixed to a support plate 21 provided inside the operating section 20. The pipe support 22 holds the holder 31 in a rotatable (oscillating) manner by clamping it from both sides. Therefore, the uppermost part of the pipe 30 cannot be angularly displaced in the direction of tilting to the left or right as shown in Figure 1, and can only be angularly displaced to rotate within a specific angular range (±45°) in a direction perpendicular to the plane of the paper in Figure 1.

[0026] With the above configuration, as shown in Figure 1(c), when the person being assisted A sways to the left or right (in the direction of the black arrow) at the toilet C, the support pipe 30 exerts a force in the opposite direction (in the direction of the white arrow), assisting the person being assisted A to return to their original posture. Furthermore, when the motor 23 winds up the wire 33, the torso support 40 is pulled up, which can support the person being assisted A in standing up.

[0027] Although not clear in Figure 1, the upper parts of the two pipes 30 are attached to the rotating support member 10 (and the operating part 20 attached thereto) at an eccentric (offset) position away from the rotating support shaft 12, as shown in Figures 2(a) and (a'). The offset amount d shown in the figure is usually set in the range of 5 to 50 cm (approximately 15 cm in the illustrated example) depending on the distance between the stopping position of the wheelchair carrying the person being assisted A and living facilities such as a toilet.

[0028] As described above, by attaching the upper part of the pipe 30 to the eccentric position of the rotating support member 10, when the rotating support member 10 is rotated horizontally, the assistance device 1 can appropriately support the movement of the person being assisted A, who is held by the body support 40, from the wheelchair to a toilet or other living equipment (transferring). In other words, from Figure 2(a) to (e), and from Figure 2(a') to (e'), as the rotating support member 10 rotates horizontally, the pipe 30 and the body support 40 change direction and also move horizontally, so that the assistance device 1 can follow the movement of the person being assisted A as they move their body forward and change direction, and support the person being assisted A.

[0029] In the example shown in Figure 2, a lock pin 14, as shown in Figure 3, is used to lock the horizontal rotation of the rotary support member 10 at an appropriate angle. Pin insertion holes 13 are provided at 90° intervals (or 45° or 30° intervals) on the fixed side surface of the rotary drive device 11. When the rotary support member 10 changes angle, the electric cylinder device 15 causes the lock pin 14 to protrude and be inserted into the pin insertion hole 13. When the lock pin 14 enters one of the insertion holes 13, the horizontal rotation of the rotary support member 10 stops. Furthermore, the horizontal rotation can be stopped at even more angular positions by arbitrarily setting the position and number of pin insertion holes 13. Alternatively, other means besides using locking pins (for example, a friction brake) can be used to stop the horizontal rotation at any angle.

[0030] Figures 4(a) and 4(b) show how the assistance device 1 installed in toilet B1 is used to support the movements of person A. Assume that person A, wearing a torso support 40 on their chest, enters the room of toilet B1 from the entrance in a wheelchair W. When the assistance device 1 is used at that time, assistance can be provided to person A for defecation in the following procedure, for example. 1) The assistive device 1, in which the rotating support member 10 is rotated to position the pipe 30 etc. closer to the entrance, is operated by an assistant (not shown) to first connect the lower part of the pipe 30 to the body support 40. At this time, the orientation of the two pipes 30 that form the support (the orientation of the center line (plane) between the two) is X1 in Figure 4(b). At this position, the rotation of the rotating support member 10 is stopped by the lock pin 14. 2) By operating the device on the control unit 20 using the attached remote control (not shown in the illustration), the wire 33 is pulled up and the pipe 30 is retracted, allowing the person being assisted, A, to stand up from the wheelchair W. 3) Similarly, the rotating support member 10 is rotated by operating the remote control or the like, and together with the torso support 40, the body of the person being assisted A is moved towards the toilet C in front, while changing its orientation by 180°. This causes the orientation of the two support pipes 30 to be aligned with the line Y, which is in the opposite direction to X1. 4) When the person being assisted A lowers their trousers, etc., the remote control or the like is operated to extend the pipe 30 and seat the person being assisted A on the toilet seat of toilet C. Even in this position, the rotation of the rotating support member 10 is stopped by the lock pin 14. 5) To respect the dignity of person A, the caregiver leaves toilet B1 and waits for person A to finish defecating. If an appropriate sensor is installed on the torso support 40, the caregiver will be notified if person A falls or otherwise slips during this time. 6) Once the person has finished defecating, the caregiver enters toilet B1 and transfers person A to wheelchair W using the reverse procedure of steps 1) to 4) above.

[0031] Figures 5(a) and (b) show examples of the use of assistance device 1 when the positional relationship between the entrance and toilet bowl C is different from that of toilet B1 in Figure 4. Toilet B2 in Figure 5(a) is an example where the direction of entry from the entrance and the front-to-back direction of the toilet bowl C are approximately perpendicular. The orientation of the two support pipes 30 to support the person being assisted A on the wheelchair W as they enter toilet B2 from the entrance is X2 in the figure, and this is a 90° angle difference from the orientation Y of the pipes 30 to support the person being assisted A at the position of the toilet bowl C. Even in such an example, the rotation of the rotating support member 10 allows the pipes 30 to follow the change in orientation and horizontal movement of the person being assisted A as they transfer between the wheelchair W and the toilet bowl C, providing appropriate support. The horizontal rotation of the rotating support member 10 is configured to be locked when the pipes 30 are in the above orientations, etc. In toilet B3 in Figure 5(b), a wheelchair W enters from the entrance and approaches the toilet C from an oblique direction. The orientation of the two pipes 30 to support the person being assisted A on the wheelchair W is X3 in the figure, and there is a 135° angle difference from the orientation Y to support the person being assisted A at the position of the toilet C. In this case as well, the pipes 30 can follow the movement of the person being assisted A as they transfer between the wheelchair W and the toilet C and continuously support their body. In this example, the pipes 30 are configured to lock horizontal rotation, including when they are in the two orientations shown that straddle the 135° angle.

[0032] In the examples shown in Figures 1 to 5, the rotating support member 10 is attached to the ceiling portion 2, but it is also possible to attach the rotating support member 10 to the upper part of the support frame 50 shown in Figure 6. In that case, it becomes unnecessary to perform installation work on the ceiling portion of the house, such as installing the rotating support member 10. As shown in Figure 6, the support frame 50 is a vertically elongated frame that stands stably on its own, with a top height of approximately 1.8m to 4m. The straight sections 51 are made of carbon fiber reinforced resin, and the bent and connecting sections 45 are made of aluminum alloy or the like, and it can be disassembled and assembled. Because the main parts are made of carbon fiber reinforced resin, it is lightweight, and it is easy to separate it at the connecting sections and disassemble it into multiple parts for transport. If the support frame 50 does not need to be transported, the main parts may be made of metal. [Explanation of symbols]
