Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a passenger conveyor, and more particularly, to an improvement in the structure of a step equipped with operating means for operating based on power reception.

(Prior Art) In recent years, some escalators (person conveyors) and escalator steps are equipped with operating means, such as wheelchair steps and light emitting devices that perform a transformation to mount a wheelchair when the wheelchair is operated. There are various methods for operating this operating means and for operating the operating means.

For example, ■ Japanese Patent Publication No. 62-4187, 61-22108
No. 2, No. 81-221084, and Special Publication No. 63 = 487
Publication No. 96 discloses that a power supply device is installed at the entrance of the main frame of an escalator, and a power reception device is installed inside the wheelchair step, and when the wheelchair step is temporarily stopped at the entrance, the power supply device is raised. We have proposed a device that allows wheelchair steps to perform a transformational operation by electrically contacting a power receiving device.

Furthermore, Japanese Patent Publication No. 83-63473 proposes a system in which power is supplied to the wheelchair steps on the outward journey while the wheelchair steps are being moved using a cord reel. Japanese Utility Model Application No. 61-135873 proposes a wheelchair step in which a light-emitting device that emits light when the wheelchair is operated and a battery that supplies power to the light-emitting device are respectively disposed in the wheelchair step. Furthermore, JP-A-13132'17 proposes a device that utilizes a rack and pinion to allow a wheelchair step to perform a transformation operation without temporarily stopping.

[Problem to be Solved by the Invention] However, in the proposal of ■■ above, due to the transformation of the wheelchair step, it is necessary to temporarily stop the wheelchair step equipped with the power receiving device at the entrance of the escalator where the power feeding device is located. Therefore, it was not possible to prevent the escalator's transportation capacity from decreasing. Furthermore, in the proposal (2) above, in order to use the light-emitting device for a long period of time, it was necessary to increase the size of the battery and to replace the battery frequently. Furthermore, in the proposal (2) above, although it is possible to make the wheelchair step perform a transformation operation without temporarily stopping it, there is a risk that the engagement between the rack and the pinion may be uncertain.

The present invention has been made in view of the above, and an object of the present invention is to provide a passenger conveyor that can eliminate the need to stop the steps, reduce the size of the battery, and ensure reliable operation of the operating means.
