As shown in FIGS. 1A, 1B, 2, and 3, a wheelchair dismounting assisting device (hereinafter also simply referred to as “assisting device”) 10 according to the first embodiment of the present invention is: It is an apparatus for assisting a wheelchair user (hereinafter also simply referred to as “user”) to get out of the wheelchair 11 by enabling attachment to the wheelchair 11 and removal from the wheelchair 11.

First, the wheelchair 11 to which the wheelchair dismounting assisting device 10 is attached will be described. Since the wheelchair 11 is conventionally known, the wheelchair 11 will be briefly described with reference to FIGS.
The wheelchair 11 has a pair of left and right side frames 12, 13. A main wheel 14 and casters 15 are attached to one side frame 12, and a main wheel 16 and casters 17 are attached to the other side frame 13, respectively. Each of the side frames 12 and 13 includes a front support column 18 whose front side is bent downward to form an L shape, and a rear support column 19 connected to an end portion (rear end portion) of the front support column 18. . The front strut 18 and the rear strut 19 further have a horizontal portion disposed at the intermediate position in the height direction, and an inclined portion that is connected to the horizontal portion and protrudes downwardly to the front side of the wheelchair 11. The upper connecting member 20 that is L-shaped, and the lower connecting member 21 that is connected to the lower ends of the front column 18 and the rear column 19 and protrudes to the front side of the wheelchair 11 and is connected to the upper connecting member 20. Yes.

An armrest 23 used by the user is attached to the upper horizontal portion 22 of each front support column 18, and a grip 24 held by an assistant is attached to the upper end portion of the rear support column 19. A brake (caliber brake) 25 is also provided at the upper end of the rear column 19 so that the assistant can adjust the speed of the wheelchair 11.
A footrest (footrest) 26 is attached to the front lower end of the inclined portion of the upper connecting member 20.
Further, on both sides of the wheelchair 11 (outside of the side frames 12 and 13) and on the front side of the horizontal portion of the upper connecting member 20 (front position from the main wheels 14 and 16), the wheelchair 11 is parked. A parking brake 27 is provided.

The left and right side frames 12, 13 are connected via folding link rods 29, 30 (link mechanisms) arranged in an X shape when viewed from below the seat 28. A flexible seat constituting the seat 28 is suspended between the horizontal portions of the upper connecting member 20. In addition, a flexible seat constituting a legrest 31 and a backrest (backrest) 32 is hung between the inclined portions of the left and right upper connecting members 20 positioned on the front side and between the left and right rear support columns 19 positioned on the upper side. Has been passed.
Therefore, when the left and right side frames 12 and 13 are opened in the left and right direction of the wheelchair 11, the folding link rods 29 and 30 are spread in an X shape, and the wheelchair 11 is held in a seatable state. Further, when the left and right side frames 12, 13 are closed, the X-shaped folding link rods 29, 30 are closed, and the both side frames 12, 13 are closed. Thus, although the wheelchair 11 can be folded in the left-right direction (width direction), the structure which cannot be folded may be sufficient.

The wheelchair dismounting assisting device 10 that can be attached to and detached from the wheelchair 11 is disposed from the front side of the seat 28 of the wheelchair 11 to the upper portion of the backrest 32 as shown in FIGS. Is supplied with compressed air (an example of compressed gas) from the front position of the seat 28 to the upper position of the backrest 32, and compressed air (or compressed air) is supplied to the seat mat 40. An electric air compressor (with an electric motor driven by a battery 49) 41 (an example of compressed gas supply means), a control box 42 in which the air compressor 41 is housed and detachably attached to the wheelchair 11; have.
This will be described in detail below.

The seat mat 40 has a bag shape, and in a deflated state where compressed air is not supplied, the seat mat 40 has an L-shaped cross section as shown by the solid lines in FIG. 1A and FIG. In the supplied and swollen state, the cross-sectional approximate right-angled triangle shape (triangular prism shape, the same applies hereinafter) as shown by the phantom lines in FIGS.
In the inflated state, the seat mat 40 has an inclined portion 43 with which a region including the user's buttocks comes into contact, and a bottom portion 44 and a back portion 45 abut against the seat 28 and the backrest 32, respectively, 47 abuts on the upper horizontal portion 22 (armrest 23) of each front column 18 from the inside. The front end position of the bottom portion 44 of the seat mat 40 is slightly behind the front end of the seat 28 (a position that does not protrude from the seat 28: the front position), and the upper end of the back portion 45 of the seat mat 40. The position is slightly lower than the upper end of the backrest 32 (position not protruding from the upper end of the backrest 32: upper position).

The shape of the seat mat 40 can be formed, for example, by joining (bonding) the fabrics forming the respective surfaces based on the shape of the seat chair mat 40 in an inflated state. It can also be formed by arranging a bendable frame material at the boundary part (side part).
The material (fabric) of the seat mat 40 is nylon (for example, nylon 6, 6 or the like) constituting an airbag or the like, but for example, other chemical fibers having flexibility and elasticity. Rubber or the like may be used. As described above, when the seat mat is made of a material having flexibility and stretchability, for example, 1) Non-stretchability such as cloth or chemical fiber is provided on each outer surface of the bottom and back of the seat mat. By attaching a shape-retaining member consisting of a sheet or low-elastic sheet, 2) a plate made of metal, plastic, wood, etc., and making the thickness of the bottom and back of the seat chair mat thicker than other parts Thus, the shape of the bottom and back can be maintained even when the seat mat is inflated.

In addition, the seat mat 40 is composed of one type of fabric, but the fabric constituting each surface described above is composed of different types of fabric (ie, the seat chair mat is composed of two or more different types of fabrics). Configuration).
For example, when the seat mat is inflated, the portion that becomes the inclined portion is made of a chemical fiber having flexibility or rubber having elasticity, and the other portion, that is, the seat mat that is connected to the inclined portion. The both sides, bottom, and back of each can be made of a non-stretchable or low-stretch fabric such as cloth or chemical fiber. Thereby, even when the seat mat is inflated, the shapes of both sides, the bottom, and the back can be maintained.

Note that the seat mat 40 is used by simply placing it on the seat 28 of the wheelchair 11, but it can also be mounted and fixed on the seat 28 of the wheelchair 11.
Specifically, the seat mat 40 is provided with temporary fixing means (not shown) for temporarily fixing the chair mat 40 to one or both of the backrest 32 and the seat 28 of the wheelchair 11. The temporary fixing means includes a hook provided on the upper portion of the seat chair mat and a surface provided on the back and / or bottom of the seat mat, which will be described later (described in the second embodiment). Fasteners can be used.
Accordingly, even when the seat chair mat 40 in a deflated state is placed on the seat 28 of the wheelchair 11, for example, the seat chair mat 40 can be prevented from slipping off from the backrest 32 of the wheelchair 11.

As shown in FIGS. 2 and 3, an air compressor 41 (which is a blower, but may be a compressor or a fan) is connected to a seat mat 40 via a hose 48 (an example of a pipe). Even when sitting on the wheelchair 11, the seat mat 40 can be inflated.
As the hose 48, a bellows-like expandable and contractible cylindrical body can be used. When the compressed air passes inside (when in use), the hose is cylindrical, and the compressed air does not pass through (when not in use). For example, a woven fabric (base fabric) or the like coated with rubber can be used. Here, the gas supplied from the air compressor 41 to the seat mat 40 is air, but may be nitrogen gas, for example.
The mounting position of the hose 48 on the seat mat 40 is the rear lower part of the side of the seat mat 40, but is not limited to this, for example, the backrest 32 of the wheelchair 11 and the seat 28. If there is a gap between the two, the back lower part of the back of the chair mat 40 may be used.

The hose 48 is provided integrally with the seat mat 40 and the air compressor 41, but via a one-touch coupler (connector) provided on the seat mat 40 side (one side) of the hose 48. It can also be made removable. Specifically, a male (or female) coupler (connector) is attached to the tip of the hose 48, and is attached to and detached from a female (or male) coupler (not shown) of the seat mat 40. It is possible. The one-touch coupler can be provided on the air compressor side (one side) of the hose, or can be provided at the center in the length direction (halfway position) of the hose.
Thus, the seat mat 40 and the air compressor 41 (control box 42) can be separated, and the auxiliary device 10 can be attached to the wheelchair 11 and removed from the wheelchair 11 with good workability.

The air compressor 41 is a small one and is driven by a battery (power source: battery) 49 shown in FIG. 3, but the air compressor 41 may be driven by using an external power source provided indoors or outdoors. it can. The battery 49 can be charged by an external power source provided indoors, for example.
The air compressor 41 is a blower having a suction port (not shown) in the center. When the air compressor 41 is stopped, this suction port serves as an exhaust port for the seat mat 40 (that is, the air compressor 41). The suction port and the exhaust port are combined, and this suction port serves as a discharge port for compressed air from the seat mat 40).

The air compressor 41 is provided with compressed gas adjusting means (not shown) that controls the air amount (gas amount) of the air compressor 41 and adjusts the inflation pressure and inflation speed of the seat mat 40. . As this compressed gas adjusting means, for example, a flow rate adjusting valve, a flow rate adjusting dial, an output regulator of the air compressor 41, or the like that adjusts the flow rate of the compressed air can be used.
The compressed gas adjusting means is directly attached to the air compressor 41, and the operation is performed, for example, 1) in advance before the air compressor 41 is accommodated in the control box 42, or 2) outside the control box 42. 3) It can be performed by an operation unit provided so that it can be operated from the outside while being exposed to 3).

  As shown in FIG. 3, the connection between the air compressor 41 and the battery 49 is turned on and off by turning on and off the main switch (main power supply) 50, and an operation switch 51 (FIG. 1) that operates when the main switch 50 is turned on. (See (A) and (B)), the air compressor 41 is operated and compressed air is supplied. When the main switch 50 is off, the air compressor 41 can be operated even if the operation switch 51 is operated. It does not operate and compressed air is not supplied.

As shown in FIGS. 2 and 3, the air compressor 41 and the battery 49 are arranged inside a control box 42 that is an openable and closable box, and a main switch 50 is provided outside the control box 42. It is provided to be operable from the outside in an exposed state (that is, the air compressor 41, the battery 49, and the main switch 50 are integrally provided). In this case, a connection connector 49a that communicates with the outside can also be connected to the battery 49, whereby the battery can be connected to the battery 49 using an external power source without opening and closing the control box 42 (without removing the battery 49 from the control box 42). 49 can be charged.
The battery 49 may be provided on the outer side (outside) of the control box 42 so as to be detachable, thereby facilitating replacement of the battery 49 (imaginary line shown in FIG. 3). A part of the control box 42 is provided with an air hole that supplies air to the suction port of the air compressor 41 (or discharges air from the exhaust port to the outside).
A hook 52 having an inverted J shape is provided on the upper portion of the control box 42, and the hook 52 is hooked on the backrest 32 of the wheelchair 11 so that the control box 42 can be detachably attached to the wheelchair 11 (loading). )it can. The mounting position of the control box 42 is not particularly limited. For example, the control box hook can be hooked on the upper end portion (including the grip 24) of the rear column 19 as a pair. Moreover, if the control box 42 can be attached to the wheelchair 11 so as to be detachable, attachment means other than the hanger can be used.

  As shown in FIGS. 1 (A) and 1 (B), the operation switch 51 is fixed to the front upper portion (front side of the armrest 23) of the front strut 18 of the wheelchair 11 by a fixing band or the like (attachment means). Has been placed. Although the operation switch 51 is disposed in front of the brake operation lever 33 of the parking brake 27, the operation switch 51 is not particularly limited as long as it is a front side position of the wheelchair 11 that can be used by an assistant (or user). For example, it may be on the armrest 23. The operation switch 51 is disposed in front of the parking brake 27 on the left side (one side) as viewed from the user sitting on the wheelchair 11, but is disposed in front of the parking brake 27 on the right side (other side).
