Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an escalator for a wheelchair, and more particularly to an escalator that improves the stopping accuracy of a specific step for loading a wheelchair at an entrance/exit area.

[Background of the invention]

Escalators have recently begun to be used in areas with a strong public nature, such as urban transportation stations, pedestrian bridges, and airports. In these fields, improvements are being made to the structure of equipment in order to expand the range of activities for people with disabilities.

However, the current escalator structure, both the installation angle and driving speed, which affect the safety psychology of users, were determined for able-bodied people, and it cannot be said that it is unsuitable for use by elderly people with physical disabilities or people with disabilities. In particular, when wheelchair users use escalators, there are safety issues such as the depth of the steps and control technology. Looking at the widespread use of escalators, transporting wheelchair users on escalators is attracting attention as a new form of escalator usage, and several improvement proposals have recently begun to be proposed.

For example, Japanese Patent Application Laid-Open No. 59-12067 discloses an invention in which a specific step is incorporated in a step row to enlarge the depth of its tread surface only when necessary. Also,
JP-A-50-71085 discloses an invention in which a device for stopping a specific step at a predetermined position in the entrance/exit section and a device for restarting it by a command device provided at the upper/lower entrance section is provided. has been done. These methods can enable the use of escalators by wheelchair users. However, these methods use a method in which an escalator operating at normal speed is stopped directly at the entrance and exit depending on a command from the entrance and exit section, and a wheelchair user is loaded onto the escalator. Although it is necessary for an escalator with a built-in specific step to stop at a predetermined position accurately, there has been no good method for detecting the specific step and stopping the escalator at an accurately determined position.

[Purpose of the invention]

An object of the present invention is to stop a specific step for loading a wheelchair at the entrance and exit by a command from the entrance, and in order to improve the accuracy of the stop, it is an object of the present invention to stop a specific step for loading a wheelchair at a certain distance from a predetermined stopping position. To provide an escalator for a wheelchair which operates more reliably by providing a switch for detecting a specific step, temporarily stopping the escalator, and entering low-speed operation in advance in addition to a fixed position stop switch.

[Summary of the invention]

A feature of the present invention is that a switch is provided at a certain distance from the entrance and exit to temporarily stop the escalator in response to a command to stop a specific step for loading a wheelchair at the entrance. This improves the accuracy of stopping at the entrance and exit.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

The present invention can be applied to any escalator structure as long as it is possible to mount a wheelchair on the treads of the steps, but in the following explanation, the method described in Japanese Patent Application Laid-Open No. 59-12067 will be used.
A case will be described in which the present invention is applied to an escalator similar to the inventions of No. 5Q and JP-A-71085.

FIG. 1 is an overall configuration diagram of an escalator of the present invention.

Of this escalator 10, 11 is a main body frame, 12 is a handrail, 13 is a step for general passengers, and a plurality of them are arranged.
4 is a specific step for loading the wheelchair. Sl is a dedicated switch for wheelchair users, and if you want to get on the train in a wheelchair, you just need to press switch S. K1 is a wheelchair-specific start switch that is activated after the wheelchair gets on the escalator, and s2. S is a stop switch that stops the specific step 14 for loading a wheelchair at the entrance and exit according to a command from the lower entrance section 8 and the upper entrance section 9;
14a is a power receiving device, 14b is a power supply device that transmits power to the power receiving device 14a, and this power supply device and the power receiving device have a structure in which they come into contact only at a predetermined position of the lower entrance/exit portion 8 or the upper entrance/exit portion 9. It is.

S4. S7 is a switch that detects a specific step for descending wheelchair operation and stops the escalator.

s, , S is a switch that detects a specific step for operating an ascending wheelchair and stops the escalator.

FIG. 2 is an enlarged view of the switch S1 that detects a specific step and stops the escalator.

FIGS. 3 and 4 show a switch S4. which detects and stops a specific step. This shows the operation order for accurately stopping the specific step 14 at a predetermined position of the upper and lower entrances 8 and 9 using Ss, Ss, and St, and the operation order will be explained using FIG. 3 as an example. . First, when a wheelchair operation command is issued using the dedicated switch S1 provided at the lower entrance/exit section 8, a specific step is detected, and when a specific step is detected by the switch S6, which stops the escalator, the escalator is stopped while operating at normal speed. The escalator is first stopped, the operating speed is changed to a low speed, the escalator is started, and the entrance and exit are controlled by the command from the lower entrance section 8, that is, the power supply device! The specific step 14 is accurately stopped at a position where the specific step 14b and the specific step 14 contact each other. As a result, stopping accuracy can be improved compared to the case where the vehicle is stopped at the entrance or exit by a command while maintaining the normal speed.

〔Effect of the invention〕

According to the present invention, stopping accuracy can be improved.
