Description

[Detailed Description of the Invention] The present invention relates to improvements to balustrades for escalators, moving walkways, etc., and particularly relates to a balustrade with a newell structure suitable for use in balustrades having protruding newell parts.

In recent years, escalator railings have become more luxurious as the design of building interiors has progressed, and the railings have been made transparent and the new well protrudes from the front surface A of the tip skirt guide 1, as shown in Figure 1. Generally, it is made into a certain shape.

Conventionally, this type of balustrade, as shown in FIGS. 1 and 2, includes a tip skirt guide 1, a skirt guide 2, a rubber handrail 3, a deck board 4, a roller 5, a shaft 6 of the roller 5, an inlet 7, and a glass. It is composed of a panel 8, a board 9, etc.

However, in the case of a method in which the rubber handrail 3 is inserted and driven without applying tension to the rubber handrail 3 in advance, the mechanism that guides the rubber handrail 3 is Since the endless length of the rubber handrail 3 is set to be slightly longer than the track, the lower part of the rubber handrail 3 will be slack.

Now, if the new well section is made to have the same shape on both the upper and lower floors, and for example the upper floor is shown in Fig. 1, the inner surface of the rubber handrail 3 is corrugated in the section 0 where the handrail 3 is running in the direction of arrow B. 5, and slack as shown by the chain line in the figure occurs.

As a result, only the loose part of the rubber handrail 3 of the shaft 6 of the roller 5 is exposed to the outside, resulting in an unsightly appearance.Even if the shaft 6 is built into the deck board 4 (not shown), the deck board 4 is exposed more than necessary, resulting in an unsightly and unsightly design.

Not only that, if the amount of slack increases, fingers, etc. can easily get caught between the side of the deck board 4 and the rubber handrail 3, which is not desirable from a safety standpoint. Regarding the handrail, if the rubber handrail 3 is operated in the direction of arrow B, accidents such as being sucked into the corner between the rubber handrail 3 and the board 9 and being compressed may occur depending on how the child plays in a dangerous manner. be done.

The present invention was devised in view of the current situation and aims to provide a handrail for an escalator, a moving walkway, etc., which has a newel structure that can prevent the slackness of the rubber handrail from being exposed to the outside.

The present invention is designed to drive the rubber handrail without applying tension in advance, and to use the deck board that guides the reversal of the rubber handrail in a parapet having a new well part that protrudes toward the boarding board side. A guide rail is provided at the deck board position to restrict the rubber handrail in the vertical and horizontal directions to prevent the rubber handrail from loosening, which often occurs in this area.

The present invention will be explained below based on an embodiment shown in FIGS. 3 and 4.

In the figure, 4 is a deck board that guides the reversal of the rubber handrail 3 with a C-shaped cross section.A glass panel 8 is stretched on the inner surface of this deck board 4, and the outer periphery is in contact with the inner surface of the rubber handrail 3. A large number of rollers 5 that rotate are attached via shafts 6.

At the lower position where the rubber handrail 3 of the deck board 4 is reversed, as shown in FIG.
Guide rails 10b that maintain a gap G of approximately m are provided, and the tips of the guide rails 10b extend to the inlet 7, and are configured so that the rubber handrail 3 does not come into contact with the hole in the inlet 7 made of rubber or the like. There is.

The guide rails 10a and 10b are shaped into the cross-sectional shape of the rubber handrail 3 so that the guide rails 10a and 10b can be inserted into the rubber handrail 3 having a C-shaped cross section and regulate the rubber handrail 3 in the vertical and horizontal directions, as shown in FIG. As shown in FIG.
Roller 11 should protrude about 1mm downward from the bottom surface of a.
There are multiple locations.

The rollers 11 rotate in contact with the inner surface of the rubber handrail 3, thereby preventing an increase in running resistance due to contact between the rubber handrail 3 and the lower surface of the guide rail 10a.

As shown in FIG. 3, a limit switch] 2 is arranged inside the deck board at the interval G position, and its detection piece 1
3 is configured to be located on a straight line connecting the lower surfaces of the guide rails 10 a and 10 b.

The limit switch 12 is configured to operate when the rubber handrail 3 loosens from its normal position toward the limit switch 12, thereby stopping the operation of the escalator.

In the above configuration, if the rubber handrail 3 is on the slack side,
The rubber handrail 3 is guided by the E portion shown in FIG. 4 to prevent it from loosening.

The running resistance at the E section is extremely small because there are few contact parts and the applied load is also small.

On the other hand, when the rubber handrail 3 is on the tension side, the inner surface of the rubber handrail 3 is applied to the guide rail 10 by the component force due to the tension.
Although the guide rail 10a tries to come into close contact with the lower surface of the rubber handrail 3, since it is guided by the rollers 11, contact between the lower surface of the guide rail 10a and the inner surface of the rubber handrail 3 is prevented.

This prevents noise caused by wear and friction of the rubber handrail 3 and guide rail 10a.

When the rubber handrail 3 is guided into the tip skirt guide 1, it passes through a hole in an inlet 7 made of rubber or the like.
The guide rail 10b prevents the rubber handrail 3 from coming into contact with the inlet 7.

When the rubber handrail 3 is running in the direction of the arrow F in Fig. 3, when a foreign object gets caught between the rubber handrail 3 and the guide rail and the running resistance of the rubber handrail 3 increases, the rubber handrail 3 experiences a so-called knocking phenomenon. vibration occurs.

At this time, the rubber handrail 3 is displaced in the vertical direction at the G section, and this can be detected by the limit switch 12.

Also, depending on how the child plays in a dangerous way, it is possible that the child may be sucked into the corner between the rubber handrail 3 and the boarding board 9. In this case, the rubber handrail 3 is moved upward at the distance G, that is, when the limit switch 12 is activated. The escalator stops.

During maintenance, the rubber handrail 3 may be removed from the railing and placed twisted and bent on the boarding board 9 or the floor.

At this time, if the guide rails 10a and 10b are integrated, the removed rubber handrail 3 will hang down from the H section shown in Figure 3, and there will be a large drop from the H section to the floor. This causes the rubber handrail 3 to twist rapidly under its own weight.

However, due to the spacing G, the rubber handrail 3 can be removed before the inlet 7, which is in a nearly horizontal state, and a smooth twisting state can be achieved all the way to the floor.

As explained above, this embodiment provides the following effects.

(1) Providing the guide rail prevents the rubber handrail from loosening, improves the appearance, and prevents accidents such as fingers getting caught between the rubber handrail and the deck board.

(2) Since the guide rail is provided with rollers, contact between the lower surface of the guide rail and the rubber handrail is prevented, and running resistance can be reduced.

(3) Since the guide rail is divided into two parts, the rubber handrail will not be adversely affected during maintenance.

(4) A limit switch is installed to automatically stop the escalator when the rubber handrail loosens, improving safety.

(5) It can be applied to existing equipment by only partially modifying it.

The present invention has been described above based on the preferred embodiments. According to the present invention, it is possible to obtain a handrail for an escalator, a moving handrail, etc., in which the slack of the rubber handrail is not exposed to the outside.
