Description

    This device relates to a device that allows a person to push on a wheelchair on the snow so that it can run on the snow without being in the snow.

  In Japanese Patent Application No. 2004-261508, a ski-like shape is combined with a wheelchair body so as to be removable by combining mechanical parts as an attachment. Japanese Patent Application No. 2000-232996 is a means to cope with a wheelchair traveling on snow in a snowy road environment by combining mechanical parts and placing a ski on the lower part of the wheelchair wheel and mechanically fixing it to the upper body part. Both of them are known to mechanically connect a wheelchair vehicle and a ski-like board.

Japanese Patent Application No. 2004-261508 Japanese Patent Application 2000-232996

  Even if the wheelchair's wheels get stuck in the snow because the wheel of the wheelchair becomes a hindrance during the winter, or the small front wheel is swayed from side to side by snow, the direction is not fixed and it is difficult to run on the snow and there is an assistant, Although it was difficult to go out of the house, the present invention was made to solve this problem.

  In order to achieve this object, a recess is provided in the center of the front edge of the plate that curves forward and the front end of the wheel is fitted, so that the wheel can be sandwiched in the longitudinal direction of the center of the plate. It solves the problem as a wheelchair ski with a standing plate.

According to the present invention, the following effects are expected.
(1) Since individual mounting brackets are not required for wheelchairs, it is easy to handle emergency detachment work.
(2) It can flexibly cope with the dimensions of various unspecified commercial wheelchairs.
(3) The wheelchair can be freely and easily moved in a desired direction.
(4) The wheelchair can be operated with the same operational feeling as normal.

It is a perspective view which shows one Example of this invention. It is sectional drawing which shows one Example of this invention. It is a perspective view which shows one Example of this invention. It is a side view which shows one Example of this invention.

Details of the present invention will be described below with reference to embodiments shown in the drawings. In FIG. 1 and FIG. 2, an insertion groove (3) for a wheel tip portion of a recess into which a wheel tip portion is fitted is provided at the center portion of the tip side of the plate (1) whose front is curved upward. Side vertical plates (2a, 2b) are arranged side by side with a width that allows the wheel to be sandwiched in the vertical direction at the center of the wheel. . The side standing plates (2a, 2b) may be cylindrical. The brake (4) is convex to the extent that it does not hinder travel and is attached to the large rear wheel (5).
The insertion groove (3) at the top of the wheel tip at the upper part receives the force moving forward at the front part and receives force from the left and right when turning left and right, and the side standing plates (2a, 2b) at the lower part are the tip of the wheel When the left and right direction is changed together with the fitting groove (3) of the part, it receives a force from the left and right.
When using under the assistance of a caregiver, place this ski in front of the front small wheel (6) and the rear large wheel (5), ride on the wheelchair, push forward, turn left and right, but remove the ski It is only necessary to reverse the length of the fitting groove (3) at the front end of the wheel and the length of the side stand (2a, 2b). Traveling stops by the operation of placing.
FIG. 3 shows the retraction bearings (8) provided on both sides of the insertion groove (3). The retraction shaft (7) having the retraction shaft fall-off prevention (7a) is pushed in from the top and inserted into the insertion groove (8). Horizontally mount 3) to make a storage frame (3a) for the tire part, and use it when necessary so that the retraction shaft (7) is caught when retreating.
FIG. 4 is a side view of a wheelchair placed on a ski.
