Description

  The present invention relates to an automatic storage structure for a footrest plate of a wheelchair, and more particularly to a structure in which the footrest plate is automatically stored on a support rod side and does not prevent a wheelchair user from getting on and off.

  As shown in FIG. 7, in the known general wheelchair footrest structure, a connecting rod A11 extends forward at the end of a support rod A1 extending from the wheelchair A, and a footrest plate B is disposed on the connecting rod A11. Connected. A sleeve B corresponding to the connecting rod A11 is installed on the plate side of the footrest plate B, and is fitted into the connecting rod A11.

  After sitting on the chair, the user first places the foot of the user with the footrest plate B horizontal. Further, when the user gets off the wheelchair A, the footrest plate B is made vertical so that the obstacle in front of the wheelchair A is removed and it is easy to stand.

  The problem to be solved by the present invention is that the connection between the sleeve and the connecting rod becomes loose, and it becomes impossible to support between the sleeve and the connecting rod, and the footrest plate suddenly drops when it is standing upright. It is a point where an accident that the person falls can occur.

  Accordingly, an object of the present invention is to provide a wheelchair footboard automatic storage structure for a wheelchair that does not hinder the user from getting off the wheelchair when the footboard is not used.

  In order to achieve the above-mentioned object, the footrest board automatic storage structure for a wheelchair according to the present invention has a footrest board, an elastic part, and a fixing part installed on a support wheel of the wheelchair. Among them, a pivotal part is installed on the support rod, and a stereotactic part is separately installed on the footrest plate in opposition to the pivotal part. The fixed part is opposed to the footrest plate and is installed on the connecting rod, and the footrest plate is positioned on the connecting rod. The most important feature is that both ends of the elastic part are respectively installed on the stereotaxic part and the connecting rod, and the footrest plate is restored when the connecting rod rotates relative to the footrest plate.

  When the footrest board is not used, the footrest board automatic storage structure of the present invention is automatically housed on the support rod side, and does not hinder the user from getting off the wheelchair. Moreover, when using it, it automatically becomes a horizontal position, and there is an advantage that the user can put his / her foot on the footrest plate by himself without helping a person.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIGS. 1 and 2, the first embodiment of the present invention includes a footrest plate 1, an elastic component 2, and a fixing component 3, which are installed on a support rod 41 of a wheelchair 4. 41 extends directly vertically from the wheelchair 4 frame.
A small connecting rod 411 extending forward is separately provided on the support rod 41, and a fitting tank 412 extending to at least one flange end is provided on the peripheral edge of the connecting rod 411.

  A pivot portion 11 having at least one pivot hole 111 is installed on the footrest plate 1, and a connecting rod 411 is inserted therein. In this embodiment, the pivot portion 11 is a storage tank having a hollow inside, and the pivot hole 111 is a part of the storage tank, and a connecting rod 411 is pivoted there. In addition, a localization component 12 facing the pivoting portion 11 is installed on the footrest plate 1, and the localization component 12 is a screw in this embodiment.

Both end portions 21 and 22 of the elastic component 2 are installed on the localization component 12 and the connecting rod 411, respectively. In this embodiment, the elastic component 2 is a spring.
The fixed component 3 is a soft sleeve having a hollow inside corresponding to the diameter of the connecting rod 411. Further, the footrest plate 1 is placed on the connecting rod 411 so as to face the end of the connecting rod 411.

At the time of assembly, as shown in FIGS. 2 and 3, the elastic component 2 is first placed in the pivot portion 11, and then the connecting rod 411 is inserted into the pivot hole 111 of the footrest plate 1 pivot portion 11. The one end 21 of the dent and elastic part 2 is inserted into the fitting tank 412 leading to the peripheral edge of the connecting rod 411 and is fitted in the fitting tank 412. Further, the other end 22 of the elastic part 2 is directly engaged with the positioning part 12 of the pivot part 11, and finally the fixed part 3 is opposed to the end of the connecting rod 411 and the pivot part 11 of the footrest plate 1 is pivoted. It inserts in the installation hole 111, and restrict | limits the footrest board 1 so that it may not slide along the connecting rod 411. FIG.
Under normal conditions, the footrest plate 1 is elastically supported by the elastic component 2 and stands vertically on the support rod 41 side, removing obstacles at the front end of the wheelchair 4 to make it easier for the user to stand and sit. .

  At the time of use, as shown in FIG. 4, when the user puts his / her foot on the footrest plate 1, one end 22 of the elastic component 2 in the footrest plate 1 is connected to another end 21 in the fitting tank 412 of the connecting rod 411. Move and move the footrest plate 1 from the vertical state to the horizontal state. When the footrest plate 1 is in a horizontal state, the elastic component 2 is compressed, and when the user's foot is separated from the footrest plate 1, the footrest plate 1 is automatically returned to the original vertical state by the elasticity of the elastic component 2. Recover and get up automatically.

  In the second embodiment of the present invention, as shown in FIG. 5, the pivoting portion 11A of the footrest plate 1 is directly molded into two opposing convex ears, and a pivotal hole 111A is formed through the convex ears. To do. Further, the localization component 12A is a casing integrally formed with the footrest plate 1, and a localization hole 121A is provided through the casing, and the one end 22 of the elastic component 2 is fitted therein to be localized. The fixed part 3A at the end of the connecting rod 411 uses a stereotaxic pin and is inserted on the coupling rod 411, and the footrest plate 1 is localized by restraining the stereotaxic pin.

  In the third embodiment of the present invention, as shown in FIG. 6, the localization component 12 </ b> B of the footrest plate 1 is formed with convex ears directly on the pivotal portion 11 of the footrest plate 1, and the fixing component 3 </ b> B is used as a latching ring. Hook it directly on the connecting rod 411. At the time of assembly, one end 21 of the elastic component 2 is fitted into the fitting tank 412 of the connecting rod 411, and the other end 22 is engaged with the localization component 12B. Further, the footrest plate 1 is restrained by the engagement ring and always positioned on the connecting rod 411.
