Abstract

PURPOSE:To aim at ensuring the safety of passengers and preventing a fencing from being damaged by providing a detector for detecting a foreign object caught between the side face outside a handrail and an adjacent structure, thus stopping the operation of an escalator. CONSTITUTION:When a passenger 10 rides with his arm, a shoulder bag 11, or the like outside a handrail 1 and the shoulder bag 11, for instance, is caught between the outer surface of the handrail of an escalator and a fall preventing fencing 5, the elastic cover 9 of a detector 6 is elastically deformed in a crushed way by the pressure of the foreign object. Accompanied by this, a bar 8 fitted/ supported inside presses either an upper or a lower limit switch 7 for its action. The jammed foreign object is detected by the ON action of the limit switch 7, and the detection signal is sent to the safety circuit of an escalator operating controller, so that the operation of the escalator is stopped immediately.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an escalator safety device, and particularly to a floor surface between the outside of the parapet near the escalator entrance and an adjacent structure such as a building wall. This invention relates to an escalator safety device that has a (for example, fall prevention) installed on top.

(Prior art) Due to the structure of the building, as shown in Figure 4, the escalator railing 1
A gap may be provided between the outside near the entrance and exit of the building and a structure such as the adjacent building wall 2. Moreover, the part of the floor 3 at the end of this gap when viewed from the entrance/exit side (the front in the drawing) may become an atrium 4 that is open vertically. In such a case, there is a risk that a person may fall from the floor 3 in the gap between the handrail 1 and the building wall 2 into the atrium 4, so a fall prevention lever 5 is provided. In addition, even if the floor 3 in the gap between the handrail 1 and the building wall 2 is continuous without being an atrium, or on the floor in the gap between the outside of the handrails of parallel escalators, there is a Road closure for prohibiting entry into
i is often provided.

(Problem to be Solved by the Invention) By the way, as described above, the fall prevention lever 5 installed between the outside of the escalator railing 1 and an adjacent structure such as the building wall 2 or the parallel escalator is not attached to the railing 1. Since there is a moving handrail, it is provided at an appropriate distance from this outer surface. The W: between the outer surface of the escalator railing 1 and the fence 5 is generally set to be 1001- or less so that no one can pass through.

However, the arms and luggage of passengers on the escalator could get caught in the gap, leading to injuries and other accidents.
There was a risk of injury due to broken pieces.

The present invention was developed in view of the above-mentioned circumstances, and is designed to automatically stop the operation of the escalator immediately when a foreign object such as a passenger's arm or baggage is caught in the gap between the escalator railing and the outside fall prevention fence. The purpose of the present invention is to provide an escalator safety device that can be stopped to ensure the safety of passengers.

(Means for Solving the Problems) [Structure of the Invention] In order to achieve the above object, the present invention provides a fence for preventing falls on the floor between the outside of the parapet near the escalator entrance and the adjacent structure. In escalator safety equipment installed with
The present invention is characterized in that a detector is provided that detects that a foreign object is caught between the outer surface of the escalator railing and the fence and stops the operation of the escalator.

(Function) In the escalator safety device of the previous GCE fA configuration, if a foreign object such as a passenger's arm or baggage enters and gets caught between the outside of the escalator railing and the fall prevention fence, the detector detects this. The escalator will immediately stop operating to ensure the safety of the passengers.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, the same reference numerals are given to the same components as those shown in FIG. 4 to simplify the explanation.

Here, a Jl 5 for preventing falling that is erected from the floor 3 on the outside of the escalator balustrade 1 is provided with a foreign object detector 6 disposed at the end of the escalator balustrade. Specifically, this detector 6 includes a pair of upper and lower limit switches 7 fixed to the upper and lower ends of the escalator rail side end of the fence 5, and a vertically long bar 8 for pushing the operating pieces of these upper and lower limit switches 7. A vertically hollow rubber cover 9 is attached to the escalator handrail side end of the dandelion 5 to support the bar 8 and cover the upper and lower limit switches 7.
It is made up of. The cover 9 is flexible enough to be elastically deformed by the pressure of a foreign object caught between the outer surface of the escalator railing and the fence 5, but has a moderate hardness that does not deform when touched by hand. be.

Therefore, when a passenger 10 gets on the train with a foreign object such as an arm or baggage, such as a shoulder bag 11 as shown in the figure, placed outside the handrail 1, the shoulder bag 11 touches the outside surface of the handrail 1 of the escalator to prevent falling. If the rubber cover 9 of the detector 6 is caught between the bottle 5 and the foreign object, the pressure of the foreign object causes the rubber cover 9 of the detector 6 to change its elasticity; Press either the upper or lower limit switch 7 to operate it. This means that the limit switch 7 is turned on and the trapped foreign object is detected, and the detection signal is sent to the safety circuit of the escalator operation controller, and the escalator operation is immediately stopped. Passenger 10 is caught in shoulder bag 11 by this.
There is no possibility that the person will fall due to being pulled or that the fall prevention lever 5 will be broken, and there is no need to worry about personal accidents such as injury.

In addition, FIG. 3 shows another embodiment of the present invention, in which a road closure is installed to prevent entry from above the floor 3 into the gap between the outside of the railings 1.1 of the escalators A and B that are installed side by side next to each other. This is an example in which a (115) is installed upright, and even if the installation conditions and shape of the (115) change, the same effect as in the previous embodiment can be obtained by providing the same detectors 6 on both ends of the rod 15. It becomes like this.

〔Effect of the invention〕

Since the escalator safety device of the present invention is constructed as described above, even if a foreign object such as baggage is caught between the escalator railing and the outside fall prevention fence, the detector will detect it. The operation of the escalator can be immediately stopped automatically, which has the effect of ensuring the safety of passengers and preventing damage to bottles.
