Abstract

<P>PROBLEM TO BE SOLVED: To enable a physically handicapped person and an elderly person to safely and easily get on and off a wheelchair and to reduce a burden on a carer by making a slide type step stand of an electric wheelchair. <P>SOLUTION: A stepping motor for sliding the step stand is driven and a footrest 12 is pulled out from a main body at the same time of turning on a power switch or by turning on a drawing switch when getting on the electric wheelchair. When turning on a housing switch, the footrest stops at a position 12a. With such a mechanism, getting on and off of the electric wheelchair can be a human action which is nearly equal to sitting-down action and standing-up action to and from a normal chair, thereby the burden on the carer is reduced. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

  The present invention relates to a walking aid.

  The footrest part always protrudes, occupies a large parking space, and it takes time to put the foot.

Problems to be solved by the invention

  In conventional wheelchairs and electric wheelchairs, the footrest plate always protrudes, and it may not be possible to turn around in a narrow space. Trying to solve problems such as raising and lowering two tables, making it easy to get on and off, making it easy to get on and off, and making it easy to get on and off by making these steps slide-type steps To do.

Means for solving the problem

  The present invention solves the problem by facilitating getting on and off by saving the space by making the footrest plate of the wheelchair and the electric wheelchair into a slide type and storing it in the wheelchair body.

  The electric wheelchair body is equipped with a slide shaft and ball bush mechanism, which is rotated by a ball screw with a stepping motor, and the step base is retracted and retracted by the movement of the nut base. Control the stop position.

  When the electric wheelchair is boarded and the power switch in FIG. 5 is turned on, or when the drawer switch is turned on, the stepping plate is moved in the direction in which the stepping plate sliding stepping motor in FIG. Rotate and the footrest plate of 12a in FIG. 1 comes out to the position of 12 and the step base drawer detection switch in 9 of FIG. 1 is turned on to stop the motor, and when getting off the electric wheelchair, the storage switch of FIG. 5 is turned on. As a result, the stepper sliding stepping motor rotates in the direction in which the footrest plate is accommodated, the position where the footrest plate 12 in FIG. 1 is retracted to the position 12a, and the position detection switch 6a in FIG. 1 is turned on. Then, after the motor stops, it is possible to get off the electric wheelchair or to make an emergency stop by the stop switch of FIG.

  In FIG. 3, the stepper sliding stepping motor is eliminated, and the footrest plate is stored and pulled out by the 22 slide step base manual lever and the 23 manual lever arm.

  FIG. 4 shows two slide rollers with 26 rollers on the left and right ends of the slide mechanism. 27 openable footrest plates with 26 hinges are pushed up by the rollers. It has something to do.

The invention's effect

  As described above, the slide type step wheelchair according to the present invention can be pulled out and stored by simply operating the switch or operating the lever, so it is almost the same as the operation of sitting or standing on a general chair. You can get on and off the wheelchair, it is safe and easy for disabled people and elderly people, and the burden on caregivers can be reduced.

It is a figure which shows one Example of the slide type step stand wheelchair of this invention. It is a top view of the slide type step stand wheelchair of the present invention. It is the side and front view of the slide type step stand wheelchair of this invention. It is a side view of the slide type step stand wheelchair of this invention. It is a control circuit diagram of the slide type step stand wheelchair of the present invention.
