Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: To provide a comb plate for a passenger conveyor, which allows a user to safely get on and off a footstep when he gets on and off a step from a doorway. SOLUTION: A step cleat groove 8 is formed on a surface portion 12 of a comb plate 6.
The anti-slip grooves 10 and 11 having a saw-tooth waveform are provided in a direction perpendicular to the above. [Effect] When the user steps on the step from the entrance / exit, even if the user steps on the comb plate with the shoe, the shoe sole is caught in the non-slip groove and does not slip, so that the user can safely get on the step.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a comb plate of a passenger conveyor.

[0002]

2. Description of the Related Art Comb plates made of a hard and smooth synthetic resin are provided at the interface between the entrance plate and the tread plate at the entrance and exit of a passenger conveyor so that users can get on and off safely. The comb teeth of the comb plate are arranged so as to engage with the cleat groove of the step, and when a user, especially an infant or an old person, descends from the step to the doorway plate, even if the shoe collides with the comb tooth, It smoothly rides on the comb board to prevent accidents.

A technique relating to a comb plate of a passenger conveyor is disclosed in, for example, Japanese Utility Model Laid-Open No. 3-72581 and Japanese Laid-Open Patent Publication No. 1-hei.
No. 321292 is cited.

[0004]

In the above-mentioned prior art, when a user gets on a step from the entrance, particularly when a child or an old person, the user may step on the comb plate and get on the step. At this time, the surface of the comb plate is smooth, so the shoes slip and hit the cleat groove of the step as it is,
There is a problem that there is a danger of falling on the steps and it is extremely dangerous.

In view of the above-mentioned drawbacks, the present invention provides a comb plate for a passenger conveyor, which allows a user to safely get on and off a foot when he / she steps on the step from a doorway. is there.

[0006]

This object is to provide a comb plate of a passenger conveyor which is endlessly connected and has a step provided with a cleat groove and comb teeth meshing with the cleat groove. It is achieved by providing a non-slip groove in a direction perpendicular to the cleat groove.

According to the present invention, the anti-slip groove of the comb plate is formed so as to have a sawtooth waveform toward the comb teeth.

Therefore, when the user gets on the step from the entrance / exit, even if the user, especially an infant or an old person, steps on the comb plate, the shoe does not get caught on the corners of the serrations of the anti-slip groove and does not slip, so that the user can ride safely. . On the contrary, when the shoe accidentally collides with the comb plate when descending from the step to the doorway, the shoe can be smoothly climbed up on the comb plate regardless of the anti-slip groove and can be safely descended.

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

FIG. 4 is a cross-sectional view of the upper floor of the passenger conveyor near the entrance / exit. In the figure, reference numeral 1 denotes an endlessly connected step, and the step 1 is rotated between a doorway 5 on a lower floor and an upper floor by a drive unit 2 via a chain 3 and a terminal gear 4. 6 is a comb plate and 5 is the doorway.
The comb teeth 7 provided at the end of the entrance / exit plate 9 provided at the front end of the comb plate 6 mesh with the step groove 8 of the step 1.

FIG. 2 is a plan view of the comb plate according to the present invention, FIG. 3 is a cross-sectional view thereof, and FIG. 1 is a detailed view showing a mounting state of the comb plate according to the present invention. In the figure, 10 and 11 are anti-slip grooves provided in the surface portion 12 of the comb plate 6 in a direction perpendicular to the cleat groove 8, and form a sawtooth groove toward the comb teeth 7 as shown in FIG. And 10a and 11a correspond to saw teeth. The comb plate 6 is fixed to the entrance / exit plate 9 with screws 15 and 16.

Next, the operation of this embodiment will be described.

Now, when an infant gets on the step 1 from the doorway 5 even if he / she accidentally steps on the comb plate 6, the shoes 10 and 11 will not slip.
Since it is hard to slip by being caught on the corners 10a and 11a of the saw teeth, it is possible to safely get on the step 1 without tipping over. On the contrary, when getting off from the step 1 to the doorway 5,
Even if the shoe accidentally collides with the comb teeth 7 of the comb plate 6, the shoe slips on the surface portion 12 of the comb plate 6 regardless of the anti-slip grooves 11 and 12.
You can ride on the comb board 6 and get off safely.

[0014]

According to the present invention, since the comb plate is provided with the serration-like anti-slip groove at right angles to the cleat groove of the step, users, especially infants and the elderly, can get on and off the passenger conveyor step safely. There is an effect that can be.
