Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a moving handrail waterproofing device for a passenger conveyor such as an escalator or a moving passage.

[Conventional technology]

The conventional general passenger conveyor and its moving handrail are
3 will be explained. FIG. 2 is a schematic longitudinal sectional side view of the passenger conveyor. In Fig. 2, 1 is the main frame of the passenger conveyor, 2 is a large number of steps that are connected in an endless manner and supported by the main frame 1 and circulated in the longitudinal direction thereof, and 3 is the step 2 on both sides of the main frame 1. The outgoing side of the handrail 4 is supported and guided by the handrail 3 and is moved in the longitudinal direction of the main frame 1 by the handrail drive device 5.
It is a moving handrail that moves in sync with the The main frame 1 is an M structure that supports the entire passenger conveyor, and the moving handrail 4 is endless and has a substantially C-shaped cross section with an inner opening 4a as shown in FIG. has been done. FIG. 3 is an enlarged sectional view taken along line I--I in FIG. 2. In Figure 3, 1& is the upper beam of the main frame 1, and 1b is the upper beam 1a.
It is a vertical column fixed to
are fixed, handrail guide brackets 1 and 7 are fixed to the brackets 1 and 6 in parallel with the vertical column 1b, and the return side handrail guide 9 is fixed to the handrail guide brackets 1-7 with bolts 1 and 8a1 and nuts 8b, etc. Fixed. The return side handrail guide 9 is disposed within the main frame 1 along its longitudinal direction, and is fitted so that the return side of the movable handrail 4 is guided and supported. In addition, the above bracket!・6 and movable handrail bracket 7
are provided at multiple locations in the longitudinal direction of the main frame 1. On the return side, the moving handrail 4 of this passenger conveyor moves with the inner peripheral opening 4a facing upward and fitting into the handrail guide 9, so water, oil, etc. can easily enter the moving handrail 4, especially outdoors. Rainwater easily enters the installed passenger conveyor. When water or oil enters the moving handrail 4 and gets wet, it slips between the rollers of the moving handrail wAllb device 5, the transmission of driving force to the moving handrail 4 decreases, and the moving handrail 4 stops. Sometimes I end up doing it. Therefore, as shown in Japanese Utility Model Publication No. 59-173674, a waterproof cover is provided below the parapet panel of the handrail to cover the inner opening on the return side of the handrail. There is a mobile handrail waterproofing device that prevents water and oil from entering.

[Problem to be solved by the invention [1] A conventional moving handrail waterproofing device for a passenger conveyor is constructed as described above, and uses a cover that is a separate member from the handrail guide.
This cover is fixed to the holder for fixing the parapet panel to the main frame using fixing devices such as screws, so compared to one without a waterproof cover, the number of parts is larger and the structure is more complicated. Installing the cover is time-consuming and expensive, and since the handrail cover and the opening on the inner periphery of the return side of the moving handrail are quite far apart in the vertical direction, rainwater that has entered the main frame can leak inside the moving handrail. There was a problem in that it was not possible to prevent it from entering the circumferential opening. This invention was made to solve the above-mentioned problems, and has a simpler structure and requires less effort to assemble than those provided with a waterproof cover. To obtain a moving handrail waterproofing device for a passenger conveyor that can sufficiently prevent water and oil from entering a side opening, ensure transmission of driving force to the moving handrail, and protect the moving handrail. It is something. [Means for Solving the Problems] A moving handrail waterproofing device for a passenger conveyor according to the present invention includes a waterproof plate that covers an inner peripheral opening of the moving handrail in a return side handrail guide that guides and supports the return side of the moving handrail. It is integrally formed.

[Effect]

The movable handrail waterproofing device of this invention has a waterproof plate integrated with the return side handrail guide, which is different from a conventional waterproof cover, and is similar to a conventional general return side handrail guide without a waterproof plate. It requires the same number of parts and assembly time, and since the opening on the inner circumference of the moving handrail is covered with a waterproof plate that is integrated with the return side handrail guide, this opening and the waterproof plate are close to each other. This can sufficiently prevent water such as rainwater and oil from entering the opening.

【Example】

An embodiment of the present invention will be described below with reference to FIG. FIG. 1 shows a sectional view corresponding to FIG. 3 showing an embodiment of the present invention. In FIG. 1, the same reference numerals as 3rlA indicate corresponding parts, and 10 is a waterproof plate formed integrally with the return side handrail guide 9 so as to be located above the handrail support portion 9a over the entire length thereof. The waterproof plate 10 is formed in a cross-sectional shape in which the left and right edges protrude outward from the left and right edges of the moving handrail 4 and are slightly bent downward, and the inner peripheral opening 4a of the moving handrail 4 is slightly bent at a position close to this. separated and covered. The height of the handrail guide 9 is increased, and the height of the handrail guide bracket 7 is decreased accordingly. Furthermore, the handrail guide 9 with the waterproof plate 10 is made of an extrusion molded product of aluminum or the like. The configuration of this embodiment other than that described above is the same as the conventional one shown in FIGS. 2 and 3. In this embodiment, the forward Is side of the moving handrail 84 moves while being guided and supported by a forward handrail guide (not shown) provided on the handrail, and the return side of the moving handrail 4 has the inner opening 4m upward. In this state, it moves while being guided and supported by the handrail support portion 9a of the return side handrail guide 9. On the return side of the movable handrail 4, a return side handrail guide 9
Since the upper part of the inner peripheral opening 4a is covered in a close position by the waterproof plate 10 integrally molded with the main frame, rainwater, oil, etc. that enter the main frame from above are sufficiently prevented from entering the movable handrail 4. If you prevent it, you will get a thorn. In the above embodiment, the moving handrail of an escalator was described, but the present invention can also be applied to a moving handrail waterproofing device of a passenger conveyor such as a moving passage having a handrail.

【Effect of the invention】

As explained above, according to the present invention, a waterproof plate is integrally formed on the return side handrail guide, and this waterproof plate allows the ffI
Since the upward facing inner opening of the moving handrail on the IWs side can be covered at a position close to this, it is possible to sufficiently prevent rainwater, oil, etc. from entering the inner opening. Therefore, the driving force can be reliably transmitted from the handrail drive device to the movable handrail, and the inner circumferential surface of the movable handrail will not get wet and stop, and the inner circumferential surface of the movable handrail can be protected. Moreover, since the waterproof plate is integrated with the return handrail guide, it solves the problems of conventional waterproof covers, and the structure requires more parts than a model without a waterproof plate or cover. The present invention is advantageous in that it is possible to obtain a moving handrail waterproofing device for a passenger conveyor that is not complicated, requires the same number of assembly steps and time, and is hardly expensive.
