Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a safety device for a passenger conveyor.

[Conventional technology]

In general, passenger conveyors are required to be extremely safe as a means of public transportation, so recently safety devices have been developed to detect dangerous phenomena mainly in the rotating parts and their surroundings, and safety devices have been installed to detect dangerous phenomena in the rotating parts and their surroundings. Safety measures are extremely extensive, such as shelves to prevent passengers from falling, shelves to prevent them from falling from the passenger conveyor itself, and protective bodies to prevent passengers on the rising passenger conveyor from colliding with the ceiling of the building. It's reaching.

As a safety device equipped with the above-mentioned protector, for example, as shown in Japanese Utility Model Application Publication No. 53-96789, a triangular protector suspended from the ceiling is generally put into practical use. Also,
As shown in Japanese Utility Model Application Publication No. 53-77991, there has been proposed a protector having a lower end fixed to the frame of the handrail and an upper end fixed to the ceiling.

[Problem that the invention attempts to solve]

By the way, in the conventional passenger conveyor safety device mentioned above, in the former case, the protective body covering the narrow corner is swingably suspended from the ceiling, so that when a passenger's body collides with it, The reaction caused the protective body to swing and separate from the moving handrail, and if the passenger was slow to withdraw his or her body, the passenger could become trapped in the narrow corner, resulting in a serious accident.
In addition, in the latter case, since the lower end of the protector is fixed to the frame of the handrail, there is a problem that passengers' hands or luggage may hit the lower end of the protector.

The present invention was made in view of the actual situation in the prior art, and its purpose is to fix the protective body covering the narrow corner part to the narrow corner part without attaching the lower end to the frame of the moving handrail. Our goal is to provide safety equipment for passenger conveyors.

[Means for solving problems]

To achieve this objective, the present invention provides safety protection for passenger conveyors by providing a protection body covering the narrow corner formed between the moving handrail and the ceiling that intersects with the moving handrail. In the device, the protector is constituted by an upright plate whose lower end is fixed to the outside deck and whose upper end is fixed to the ceiling through brackets.

[Effect]

Since the present invention is constructed as described above, the lower end of the protector is fixed to the outside deck, and the upper end is fixed to the ceiling via brackets, and between the movable handrail and the ceiling. It is designed to cover the narrow corner that is formed. Thereby, the protector can be fixed to the narrow corner portion without attaching the lower end portion to the frame of the moving handrail.

〔Example〕

Hereinafter, the safety device for a passenger conveyor according to the present invention will be explained based on the drawings.

FIG. 1 is an overall side view showing one embodiment of a safety device for a passenger conveyor according to the present invention, and FIG. 2 is a longitudinal sectional view of an essential part of the passenger conveyor taken along line - of FIG.

As shown in FIG. 1, this passenger conveyor is installed between a landing floor 1 and a floor 2 that constitutes the upper floor of this floor 1.
is provided. And on the passenger conveyor,
A step 4 that rotates endlessly, a balustrade 5 erected on both sides of the balustrade 4, a movable handrail 6 provided on the top of the balustrade 5 and that rotates in synchronization with the step 4, and a step 4 at the base of the balustrade 5. Inner deck 7 and parapet 5 in Figure 2 that cover the side
An outer deck 8 is provided that covers the opposite side of the steps 4 at the base.

Furthermore, a protector 9 is provided to cover the narrow corner A formed between the moving handrail 6 and the ceiling 3 intersecting with the moving handrail 6. The protector 9 has a lower end fixed to the outer deck 8 via a bracket 10, an upper end fixed to the ceiling 3 via a bracket 11, and a cylindrical protective edge 12 erected at the front end. has been done.

In this embodiment, when a passenger who is moving from floor 1 to floor 2 on the upper floor approaches the narrow corner A while leaning outside the moving handrail 6, the passenger who is moving from the floor 1 to the floor 2 on the upper floor approaches the narrow corner A. Since the passenger hits the protective edge 12 of the protective body 9 and is pushed back, the passenger is prevented from getting caught in the narrow corner A, and therefore, no serious personal injury occurs. Furthermore, since the lower end of the protector 9 is fixed to the outer deck 8, the lower end of the protector 9 will not be hit by passengers' hands or luggage.

[Effect of idea]

Since the present invention is configured as described above, the protector is fixedly installed at the narrow corner without attaching the lower end to the frame of the moving handrail, thus preventing passengers from getting caught in the narrow corner and causing serious personal injury. This has the effect of not only preventing this from happening, but also preventing passengers' hands, luggage, etc. from hitting the lower end of the protector.
