JPH08198572A - Comb plate device for passenger conveyor - Google Patents

Abstract

PURPOSE: To prevent a shoe or the like from being put between a comb plate and a footstep at a landing. CONSTITUTION: An insertion suppressing means formed of a shaft 2C and discs 2B connected to the shaft 2C is fitted in such a way that each disc 2B enters into a groove 1A, and a torque transmission means 3 for rotating the discs 2B in such a way that the exposed parts of the discs 2B move in the same direction as footsteps at the time of operating a passenger conveyor is fitted to the shaft 2C. The overturn or the like of a passenger is thereby prevented to improve safety.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a comb plate device for a passenger conveyor such as an escalator and an automatic line.

[0002]

2. Description of the Related Art As disclosed in Japanese Laid-Open Publication No. 85-1188, a comb plate having teeth that enter grooves formed at equal intervals on a tread surface of a step is provided at an entrance / exit of a passenger conveyor for safe entry / exit. I am able to do it.

[0003]

However, depending on the condition, position, material, riding style, etc. of the bottom of the shoe, the shoe may be caught between the teeth of the comb plate and the step.

An object of the present invention is to provide a comb plate device for a passenger conveyor which can prevent shoes or the like from being caught between the comb plate and the step at the entrance / exit of the passenger conveyor.

[0005]

The above object of the present invention is to endlessly connect a plurality of steps in which grooves are formed at equal intervals on a tread surface, and to circulate between two entrances and exits. In a passenger conveyor comb plate device having a comb plate having teeth that enter into each groove at each entrance / exit, each disc inserts a pinch suppression means consisting of a shaft and a disc connected to this shaft into each groove. As described above, by attaching the rotating plate to the front shaft, the disc is rotated so that the exposed portion of the disc moves in the same direction as the step when the passenger conveyor is operated. To be achieved.

[0006]

[Function] Since the disc is rotated upward as described above, even if shoes or the like are likely to be caught between the disc and the step, the shoes and the like are pushed up above the groove, Prevent it from being drawn to the bottom of the.

As a result, it is possible to prevent shoes or the like from being caught between the disc and the step.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view of an essential part of an embodiment in which the present invention is applied to an escalator, FIG. 2 is an enlarged sectional view of the essential part, and FIG. 3 is a plan view of the essential part.

In the figure, reference numeral 1 denotes a step, which is connected endlessly and circulates between two entrances / exits, for example, the entrances / exits on the first floor and the second floor.

The tread surface of the step 1 has grooves 1 at equal intervals.
A is formed.

Reference numeral 2 is a comb plate arranged at the entrance / exit, and has a disc 2B having a width that fits into the groove 1A, a common shaft 2C for supporting the disc 2B, a disc 2B, and a common shaft 2
It is composed of a pressing plate 2D that rotatably attaches C to the comb plate 2.

The discs 2B and the teeth 2A are arranged every other one so as to enter the grooves 1A.

Reference numeral 3 is a rotational force transmitting means, which is a sprocket 3A fixed to the end of the common shaft 2C, and a sprocket 3 which meshes with a handrail drive chain 4 of the escalator.
B, a sprocket 3C mounted on the same shaft as the sprocket 3B, and a chain 3D hung between the sprockets 3A and 3C.

The number of teeth of each sprocket 3A, 3B, 3C is selected so that the peripheral speed of the disc 3B is about the same as that of the step 1.

During operation of the escalator, the handrail drive chain 4 is running, and the sprocket 3b meshing with it is rotating. This rotation is transmitted through the sprocket 3C, chain 3D and sprocket 3A to the common shaft 2C. Be transmitted to. As a result, the exposed portion of the disc 2B rotates in the same direction (upward) as the moving direction of the step 1.

Therefore, even if the shoes arrive at the comb plate 2 with the shoes slightly entering the groove 1A, the shoes etc.
Since it is lifted up by B, the groove 1A for shoes etc.
The part inside is pulled up from the inside, and can be prevented from being caught between the disc 2B and the teeth 2A and the step 1. Further, since the discs 2B and the teeth 2A are alternately arranged, it is possible to have both the trapping prevention effect of the rotating circular field 2B and the trapping prevention effect of the stationary tooth 2A, which may cause various modes of trapping. Also, it can be expected to have a suppressing effect.

In the above embodiment, the disc 2B is formed in the groove 1.
Although they are arranged at intervals of every other piece, they may be provided so as to face all the grooves 1A.

[0019]

According to the present invention, it is possible to prevent shoes or the like from being caught between the comb plate and the step at the entrance / exit of the passenger conveyor, thereby reducing the fall of passengers and improving safety. Can be improved.
