JP2010137982A - Escalator with footstep for wheelchair - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a footstep for a wheelchair easy for inspection in a simple structure, without requiring a bumping post for the wheelchair, while improving stability in the wheelchair on the footstep for the wheelchair, in an escalator with the footstep for the wheelchair incorporated with the footstep for the wheelchair. <P>SOLUTION: This footstep for the wheelchair can simplify a structure of the footstep by omitting the bumping post, by constituting so as to secure stability with front-rear wheels 3A and 3C of the wheelchair 3 and multi-point support of a bottom surface 3B, by forcing up the tread 2B of the footstep 1B for the wheelchair not contacting with the front-rear wheel 3A and 3C of the wheelchair 3 up to the level contacting with the bottom surface 3B of the wheelchair 3. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a wheelchair stepped escalator in which a wheelchair stepped step is incorporated.

  FIG. 3 is a partial sectional view showing an example of a conventional wheelchair stepped escalator, partially showing the inside of the step.

In FIG. 3, as a safety device for maintaining stability of the wheelchair 3 placed on the wheelchair step to be connected during operation of the escalator with a wheelchair step, a vehicle stop member 10 that can be moved up and down, a motor for raising and lowering a vehicle stop member not shown, There is known a structure in which a drive mechanism constituted by a gear or the like is disposed in a wheelchair step 1C so that a wheel stopper is pushed out on the wheelchair step 1C when the wheelchair is loaded.
Japanese Patent Laid-Open No. 10-297857 (FIG. 3)

  All of the conventional safety devices are housed in the wheelchair step during normal operation and project the wheel stopper member from the surface of the wheelchair step during wheelchair transport. However, the stability of the wheelchair on the wheelchair step is insufficient.

  In addition, since it has a vehicle stop function, a drive mechanism composed of a vehicle stop member, a vehicle stop member raising / lowering motor, a gear, and the like is required, which makes the structure complicated and causes inspection complexity.

  The object of the present invention is to improve the stability of the wheelchair on the wheelchair step, omit the wheel stop member on the tread surface of the wheelchair step and the drive mechanism for raising and lowering the wheel stop member, and simplify the structure to facilitate inspection. The purpose is to provide a wheelchair step.

  In order to achieve the above-mentioned object, the present invention enables a safety device for maintaining the stability of a wheelchair placed on a connected wheelchair step to be able to move up and down the entire tread surface of the wheelchair step where the wheelchair step does not contact the wheelchair front and rear wheels. The wheelchair step surface is applied to the lower part of the wheelchair frame when the wheelchair is conveyed, and the vehicle stop member and the vehicle stop drive mechanism are not provided.

  According to the safety device for an escalator with a wheelchair step of the present invention, the wheelchair step surface that is not in contact with the wheelchair front and rear wheels of the wheelchair step to be connected can be raised and lowered higher than the wheelchair step surface with which the wheelchair front and rear wheels are in contact. Therefore, the lower part of the wheelchair frame and the front and rear wheels of the wheelchair are supported at multiple points, so that the stability of the wheelchair on the wheelchair steps during wheelchair transportation can be ensured, and the drive mechanism for raising and lowering the wheel stopper and the wheel stopper can be omitted. It is.

  Hereinafter, an embodiment of a wheelchair stepped escalator according to the present invention will be described with reference to the drawings.

  FIG. 1 is a side sectional view of an escalator with a wheelchair step according to the present invention, and FIG. 2 is an enlarged view of a main part of the escalator with a wheelchair step according to the present invention.

  In FIG. 1, a step 1B where the front and rear wheels 3A, 3C of the wheelchair 3 to be transported is raised by a lifting link 4A so that it is raised higher than the steps 1A, 1C to which the front and rear wheels 3A, 3C of the transported wheelchair 3 are in contact. By holding up the tread surface 2B of the step 1B with the bottom surface 3B of the wheel 3, the wheelchair 3 is held together with the front and rear wheels 3A, 3C.

  In FIG. 2, since the step 1B and the steps 1A, 1C have different heights, the connecting portions 5A, 5B of the step 1B are arranged at the same height as the connecting rods 7A, 7B via the brackets 6A, 6B.

  When transporting the wheelchair 3 with the escalator with a wheelchair step according to the present invention, the steps 1A, 1B and 1C are brought into the same plane at the upper and lower entrances (not shown), and then the rear wheel 3C of the wheelchair 3 is stepped on. The front and rear wheels 3A of the wheelchair 3 are moved up by bringing the wheelchair 3 into a position where it does not protrude from 1C, and raising the tread surface 2B of the step 1B where the front and rear wheels 3A and 3C of the wheelchair 3 do not contact with the bottom surface 3B of the wheelchair 3. Multi-point support of 3C and bottom surface 3B. This eliminates the need for the vehicle stop member and the vehicle stop drive mechanism that are conventionally required.

  Further, an ascending operation of the step 1B is performed by an attendant (not shown) from a normal operation to a wheelchair operation mode, after the wheelchair 3 is put on the steppings 1A, 1B, and 1C by an operation button (not shown), and the stop position of the step 1B. Contact between the tread surface 2B and the bottom surface 3B of the wheelchair 3 is made by visual confirmation by an attendant (not shown), but a load sensor (not shown) is provided on the tread surface 2B of the step 1B, and an operation button (not shown) is disabled by the operation of the load sensor. It is also possible to stop the ascent.
