Abstract

(57) [Summary] (Correction) [Structure] Movable body 1 provided at the entrance of the circulating handrail
6 and means for stopping the passenger conveyor by detecting the displacement of the movable handrail in the traveling direction of the movable body 16, fixed around the movable body 16 installed inside the protective body 19. The body 15 is installed and displacement of the movable body 16 is suppressed. [Effect] When a strong impact force caused by mop cleaning or the like is generated in the safety device, it can function as a movable body and can retain the function of the safety device by electrical restoration.

Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a passenger conveyor having a safety device at the entrance of a moving handrail.

[Prior Art]

 In general, the passenger conveyor is configured so that the outward side of the circulating handrail is designed along the periphery of the balustrade, and the returning side enters inside the lower part of the balustrade. A safety device such as that disclosed in Japanese Patent Laid-Open No. 56-48388 is provided at the entrance of the moving handrail at the lower part of the balustrade, and when the external force is applied to this safety device, the inside of the safety device is detected. The switch shuts off electricity and stops the operation of the passenger conveyor.

[Problems to be solved by the device]

 In the above conventional technology, a part of the safety device is composed of a spring plate which is a movable body, and the safety device is operated when the spring plate is retracted by an external force. When the mop hits and a strong impact force is applied, the spring plate becomes excessively deformed, a part of the spring plate rises to the upper part, and the head of the detection switch does not ride up to return to the normal position. The current situation is that it has not been applied to actual devices because of the problem that it will no longer function. An object of the present invention is to provide a passenger conveyor that does not change the internal structure of the safety device and always performs a stable function.

[Means for Solving the Problems]

 In order to achieve the above object, the present invention comprises a protective body and a movable body provided at the entrance of a circulating moving handrail, and stops the operation when the movable body is displaced in the traveling direction. In the passenger conveyor having the safety device, a fixed body is provided around the movable body to suppress the displacement of the movable body.

[Action]

 Since the present invention is configured as described above, since the movable body comes into contact with the fixed body when retracted by a certain amount, the function as a safety device is stabilized without floating unlike the conventional case.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. As shown in FIGS. 3 and 4, the passenger conveyor, for example, the escalator, is connected to and rotates in an endless manner. It is provided with a balustrade 3 which is erected along both sides, a moving handrail 4 which moves the periphery of the balustrade 3 in synchronization with the tread 1, and a frame body (not shown) installed to support these. There is. The balustrade 3 is provided with a balustrade panel 5 which is supported by a frame and stands upright, a handrail frame 6 which guides a moving handrail 4 attached to the periphery of the balustrade panel 5, and a frame of a little panel 5. It is provided with an inner deck cover 7, an outer deck cover 8 and a skat guard 9 which cover the support portion to the body. A safety device 10 is installed at the entrance of the moving handrail 4 of the skirt guard 9. 1 and 4, the safety device 10 is roughly divided into a fixed support 13 installed inside, which is surrounded by an inner deck cover 7, an outer deck cover 8 and a skirt guard 9, and this fixed support. A movable body 16 composed of a spring plate fixed to the body 13 by a fastening member (bolt) 14, a fixed body 15 placed at a position in contact with a part of the movable body 16, a rubber body protector 19, and a fastening body. The member 17 is composed of a detection switch 18 and the like mounted on the fixed support 13. During operation of the escalator equipped with the safety device configured as described above, a cleaner cleaning the area around the entrance / exit 2 accidentally accidentally pokes the protector 19 and the movable body 16 therein with a mop. If the movable body 16 is displaced and the detection switch 18 is operated to stop the escalator, the movable body 16 tries to float above the detection switch 18, but the movable body 16 comes into contact with the fixed body 15 during the displacement. Since the displacement is suppressed (the gap g in FIG. 5 is zero) and the position is maintained at the steady state, the function of the safety device is continued only by the electrical restoration.

[Effect of the device]

 According to the present invention, when a strong impact force is applied to the safety device, the function of the safety device is not impaired, and a highly safe passenger conveyor capable of maintaining its function can be obtained at all times.
