[0001]

[Industrial applications]

 The present invention relates to a wheelchair.

[0002]

[Prior art]

 Conventional wheelchairs are generally composed of a seat, a backrest, armrests on both sides, a chair made up of a footrest plate, and wheels, but these days, in response to demands from consumers, etc. Various improvements have been made. For example, if the armrest part rotates backward on the backrest side to open the side of the seat space, it is possible to get on and off from either the front or the side, or if the footrest plate is depressed. There were some improvements such as a mechanism to apply the brake, which reduced the burden on the caregiver and improved safety.

[0003]

[Problems to be solved by the device]

 However, in all wheelchairs, the front part of the seat space was always open, so in this state, wheelchair users with disabilities in their legs or Due to psychological anxiety (risk of falling to the front), there was a problem in that the body naturally exerted force and struggled strangely (holding both armrests and exerting force on the back). Therefore, since the wheelchair users had a bad posture and a burden on their bodies, there is a strong demand for a wheelchair that provides a psychological sense of security.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a wheelchair that can provide a psychological sense of security. Another object of the present invention is to provide a hand rest structure that can withstand a pressing force from above.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the technical means made by the present invention is to provide a receiving portion on the front surface of the armrest portion, and to rotate the hand placing member to the left and right so as to block the front of the seating space outside the side surface of the receiving portion. The lower surface of the hand-placing member is held in contact with the upper surface of the receiving portion.

[0006]

[Action]

 With the above technical means, the front part of the body can be blocked by the hand rest member, and a psychological sense of security can be created by placing the hand on the hand rest member. Further, since the lower surface of the hand placing member is held in contact with the upper surface of the receiving portion, the burden on the shaft attaching portion of the hand placing member is reduced.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In the figure, A shows an embodiment of a wheelchair of the present invention, which is constructed by providing a wheelchair body 1 with a hand rest member 4. The wheelchair body 1 includes a seat portion 2a, a backrest portion 2b, an armrest portion 2c. Although it has a conventionally known shape formed by the chair portion 2 including 2c and the footrest portion 2d, and the wheels 3, it is merely an example and is not limited to this. It can be changed to one.

The hand-placing member 4 is formed with a flat plate-shaped hand-placing plate 5, and a mounting piece 6 is fixed to a rear surface 5 a of the hand-mounting member 4. A support shaft 13 is rotatably attached to a support piece 13 provided on an outer side 12a of a side surface 12 of a receiving portion 11 provided on a front surface 2c 'of the c so as to be rotatable left and right. In the illustrated example, both armrests 2c. 2c front surface 2c '. 2c 'are provided one by one, and the hand-placing member 4.4 is an armrest 2c. It is arranged so as to be rotatable left and right in front of 2c, and is held substantially parallel to the road surface (y) in front of the seat space (x).

The hand-placing plate 5 is formed of a desired material (resin material, wood, etc.) to a desired length and thickness, and has a thickness equivalent to the diameter of the receiving portion 11 of the present embodiment described later, and Both armrests 2c. 2c ahead of each tip 5c. 5c, the armrests 2c. It is needless to say that it is a thick-walled flat plate formed to have a length extending between 2c and may be used as a table, and further, as shown in the drawing, a desired depression 7 is provided and a cup or bottle holder is provided. Alternatively, it may be used (convenient when taking medicine, etc.), or may be made into a hole by penetrating the recess 7 and a bag (not shown) may be hung vertically to be used as a storage case (coin purse) or the like.

Further, the hand-placing plates 5.5 may have different lengths without being limited to the same length, and the shape thereof is not limited to the above-mentioned flat plate shape, and other shapes such as a desired cross-sectional shape (circular shape, The shape is arbitrary such as a straight bar shape having a polygonal shape or a curved bar shape.

The mounting piece 6 is a flat metal plate having a thickness equal to the thickness of the rear surface 5a of the hand placing plate 5 and approximately half the length (width) of the rear surface 5a. A support piece 6a is integrally formed at one end in a downwardly inclined shape, and the mounting portion 6b is fixed to a recess 5a 'provided on the rear surface 5a of the hand placing plate 5 with bolts 8 and 9 or the like. An insertion hole 6a 'for the support shaft 15 is formed in the center of the support piece 6a.

The bolt 8 is preferably long enough to penetrate from the rear surface 5 a to the front surface 5 b of the hand placing plate 5 in order to strengthen the mounting and fixing surface. It should be noted that the embedding hole 10 should be provided in the front surface 5b so that the tip 8a of the bolt 8 does not project to the front surface 5b of the hand placing plate 5.

The receiving portion 11 is provided on the front surface 2c 'of the armrest portion 2c, and in this embodiment, the support rod 12 of the armrest portion 2c is extended in the front direction to have a rod shape. The support piece 13 is projectingly provided on the outer side 12a 'of the side surface 12a. Further, an insertion hole 13a for the support shaft 15 is formed in the center of the support piece 13. In addition, in this embodiment, the rod diameter of the receiving portion 11 is set to be approximately the same as the thickness of the hand-placing plate 5. However, the diameter is not limited to this, but the upper surface 11 'of the receiving portion 11 is preferably wider. .

It should be noted that the shape of the receiving portion 11 is merely an example and is not limited to this, and can be changed as appropriate. In this example, the support rod 12 of the armrest portion 2c is extended. At most, it is provided integrally with the armrest portion 2c, but only the receiving portion 11 may be separately formed by rising from the main body frame rod 14, and the armrest portion 2c and the integral body may be formed separately.

Therefore, the supporting piece 6a of the hand-placing member 4 configured as described above is made to coincide with the supporting piece 13 provided on the outer side 12a of the side surface 12 of the receiving portion 11, and the insertion holes 6a '. 13a are made to communicate with each other, and when the support shaft 15 having a desired length is rotatably attached, the hand rest member 4 is set to the left and right rotatable state in front of the armrest portion 2c of the wheelchair body 1. The other side is set in the same way. Further, in this embodiment, the support shaft 15.15 is separately covered with the cover 16.16 made of rubber, resin material or the like.

Therefore, when the caregiver pushes from behind to move or take a walk, after the user sits down, the hand rests 5.5 are inserted from the outside to the inside as shown by arrows (a) in FIG. 5, respectively. To the upper surface 11 'of the receiving portion 11 and to rotate the front end 5c. When 5c are abutted against each other, the hand placing plate 5.5 is held flush with the front of the seat space (x) and substantially parallel to the road surface (y). You can place your hand on the hand rest 5.5, which is psychologically reassuring. Further, since the lower surface 5d is held by the upper surface 11 'of the receiving portion 11, the burden on the shaft mounting portion (z) by the support shaft 15 is small.

Further, in this embodiment, the receiving portion 11 extends forward with its front portion further downward, and together with the body frame rod 14, forms a desired space (v). Since the hand placing plate 5 can be stored therein, when the hand placing plate 5 is not used, the hand placing plate 5 can be pivoted outward and stored in the space (v) so as not to interfere.

In this embodiment, the hand rest member 4.4 is attached to both armrests 2c. 2c respectively, but the hand rest member 4 of a desired size (for example, one that can be expanded and contracted to a length extending between both armrests 2c and 2c) is provided only on one armrest 2c side. May be

[Effect of device]

 Since the present invention is configured as described above, it is possible to provide a new wheelchair that provides a psychological sense of security. That is, when a wheelchair user is placed, the hand rest member is rotated outward to open the seat space for convenience of riding, and after riding, the seat space is directed toward the front of the seat space. Pivot left and right to position the hand rest on the front of the body (in front of the seat space) to block the front of the seat space and place a hand on the hand rest to provide psychological relief. Because it is born, it is possible to relax and ride with a relaxed feeling, and the user does not have to take an unreasonable posture by naturally exerting force on the body as in the past and without taking an unreasonable posture. It is very useful and safe as well as meeting the needs.

Further, since the lower surface of the hand placing member provided as described above is held in contact with the upper surface of the receiving portion, the load on the axial attaching portion between the hand placing member and the receiving portion is small, and the axial attaching portion is small. It can withstand long-term use with little risk of early breakage.
