JPH09165180A - Escalator device for wheelchair - Google Patents

Abstract

PROBLEM TO BE SOLVED: To facilitate manual operation by providing weight steps, equal in weight to wheelchair steps, at steps positioned at half of the total number of steps counting from wheelchair steps. SOLUTION: A wheelchair step 11 used for a physically handicapped wheelchair pasenger is constituted in such a way as to have wheelchair montable area by moving an upper tread 11A backward. In the case of using forty-two steps 5 for this escalator, weights 12A are installed at the twenty-first steps counting from wheelchair steps 11 that are half of the total number of the steps 5 so as to arrange weight steps 12 equal in weight to the wheelchair steps 11. At the time of turning the rotary shaft of a driving machine using a handle to manually operate the escalator in the maintenance work of a wheelchair escalator device, the weight of the wheelchair steps 11 positioned on the moving side is offset by the weight of the weight steps 12 positioned on the return side, so that the labor of manual operation is reduced.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an escalator device for a wheelchair.

[0002]

2. Description of the Related Art A conventional wheelchair escalator is provided with a rearward moving step adjacent to a preceding step in order to hold a wheelchair horizontally, and a movable step such as a cylinder device, an electromagnet or a motor is provided in the rearward moving step. This allows the wheelchair to be raised and lowered to a height at which it can be held horizontally. This technique is described in Japanese Patent Laid-Open No. 4-72293.

[0003]

In the above-mentioned prior art, the backward moving step, which is a wheelchair step, is provided with a device such as a motor for making the tread surface at the same height as the preceding step and a battery for driving. The weight is about 100 kg, which is about four times the weight of a general step. For this reason, during maintenance work, when the drive machine shaft directly connected to the drive motor shaft of the escalator is manually turned by a chain or handle to move the escalator, the wheelchair steps can be moved by passengers. When it is located on the side of the wheelchair, and when the wheelchair steps are located on the return side where the wheelchair steps are reversed from the exit of the moving side and moved to the entrance, labor is required to increase the fatigue of the worker. was there.

An object of the present invention is to provide an escalator device for wheelchairs which can be easily operated manually.

[0005]

In order to achieve the above object, the present invention provides a plurality of steps which are arranged in a main frame of an escalator and which are connected to each other in an endless manner that cyclically moves, and the plurality of steps. In an escalator device for wheelchairs having an intervening wheelchair step, the steps which are counted from the wheelchair steps and are located at half the total number of steps are provided with weight steps having the same weight as the wheelchair steps. is there.

[0006] As described above, the wheelchair steps and the weight steps in the plurality of steps connected endlessly are arranged in a good load balance, and the manual operation can be performed with the same force for raising and lowering.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a sectional view of a wheelchair escalator device of the present invention, and FIG. 2 is a perspective view of a weight step of an embodiment of the wheelchair escalator device of the present invention.

In the figure, each bearing of the inclined portion 1a of the support frame 1 of the escalator, which is installed to be inclined between the floors of the building, has an upper sprocket (not shown) and a lower sprocket (not shown) which are supported shafts 2a, 3a. Is rotatably mounted on the shaft, and a guide rail 4 is provided in a loop shape between the upper sprocket and the lower sprocket (not shown). Further, a transmission chain (not shown) is wound around an upper sprocket and a lower sprocket (not shown) located outside the guide rail 4, and a plurality of steps 5 are attached to the handrail panel 6 on the transmission chain (not shown). It is provided so as to move in synchronization with the wound moving handrail 7. A chain 9 is wound around the upper sprocket (not shown) and the drive machine 8, and the rotation of the drive motor 10 is transmitted to the upper sprocket (not shown) via the drive machine 8 and the chain.

Further, the wheelchair steps 11 used by wheelchair passengers for physically handicapped persons are constructed so that an upper tread surface 11A is moved rearward so that a wheelchair (not shown) can ride on the area. Furthermore, the steps 5 of this escalator are 4
Two pieces are used, and a weight 12A is installed on the 21st step counting from the wheelchair steps 11 which is half the total number of steps 5, and a weight equivalent to that of the wheelchair steps 11, for example, 1
A weight step 12 of 00 kg is arranged.

In the wheelchair escalator device constructed as described above, when the escalator is manually operated by rotating the rotary shaft of the drive machine 8 using a handle (not shown) at the time of maintenance work, the weight of the wheelchair steps 11 located on the moving side. However, since the weight of the weight step 12 located on the return side is offset, the labor of manual operation can be reduced.

[0012]

According to the present invention, the wheelchair steps and the weight steps are arranged such that when one is on the moving side and the other is on the return side, the wheelchair steps and the weight steps offset the respective weights. Therefore, it is possible to raise and lower the manual operation with the same force and reduce the labor of the maintenance work.
