Description

[Detailed description of the invention] (a) Technical field The present invention relates to the handrail of a passenger conveyor such as an escalator or an electric road, and the invention relates to the fixing of a main deck board made of a particularly thin plate and an auxiliary deck board provided at the outer end of the main deck board. The present invention relates to a parapet structure suitable for increasing the productivity of parts and the ease of assembly through improved methods.

(b) Prior Art In FIG. 1, the escalator's handrail is disposed on the upper side of a main body portion comprising a main frame 2, a driving device 3, a step device 4, and the like.

In the conventional structure shown in FIG. 2, a support column 5 is fixed to a main frame 2, and a bent bracket 6 is fixed to the upper end thereof by welding or the like.

The bracket 6 is provided with mounting holes 7, 8, and 9, and an auxiliary deck board 10 for adjusting the connection of the exterior support and the architectural wall A is fixed to the right end with set screws 11. On top of that, the main deck board 12 is fixed to the bracket 6 with a set screw 13 together with a guide rail 14A that guides the handrail belt 14. At this time, the inner surface panel 1
5 can also be installed.

On the other hand, a presser foot 16 is pre-installed on the right side of the main deck board 12 to hold down the U-shaped bent end. The mounting method is to use the reaction force of tightening the bolt to secure it in place.

According to the above configuration, the shape of the bracket 9 is complicated, and the upper surface of the main deck board 12 may be deformed due to manufacturing errors in the bending dimension H, or the main deck board 12 may not be installed horizontally, and the set screw 17 welded to the presser foot 16 may Dislodgement of welded parts when over-tightened,
Also, the presser foot 16 itself may be bent.

Also, after installing the main deck board 12,
If it becomes necessary to adjust the mounting position of the auxiliary deck board 10 to the left or right, the main deck board 1
It was necessary to loosen both the screw 17 of the second side presser foot 16 and the set screw of the auxiliary deck board 11.
Furthermore, the head of the set screw 11 is in a narrow space,
Inserting and tightening tools such as screw tightening tools was difficult and time consuming.

(c) Purpose of the invention This invention was made to eliminate the above-mentioned drawbacks, and it is useful when adjusting the width direction of the main deck board, which consists of thin boards for the handrails of escalators, etc., and the auxiliary deck board, which is provided overlapping the outer edge of the main deck board. The purpose of this invention is to simplify the work and to improve the productivity of parts and assembly work by simultaneously fixing the outer end of the main deck board and the auxiliary deck board. Embodiments of the present invention will be described below with reference to the drawings.

(d) Structure of the invention In Fig. 3, the support column 5A fixed on the main frame 4 is slightly longer than the conventional one by H-h.
An L-shaped bracket 6A is integrally attached to its upper end by welding or the like. Mounting screw holes 7A and mounting holes 9 are provided on the upper surface of the bracket 6A.

Then, stacked on top of it, seat 19,
The main deck board 12, guide rail 14A, handrail belt 14, etc. are installed in sequence.

On the other hand, a main deck board 12 is provided at the right end, the outer end of which is formed in a U-shape so as to enclose the end of the bracket 6A.
0 are provided with pre-set laterally adjustable mounting holes. Further, a washer 20 having an optimum thickness t is inserted between the auxiliary deck board 10 and the bracket 6A, and is interposed and sandwiched together with the main deck board 12 so that they are simultaneously fixed together from below by setscrews 11.

(e) Function of the invention According to the invention, the bracket 6A can be bent in one place instead of three, and drilled in two places instead of three.
Because there are fewer parts, processing and installation time for parts is reduced.

The work of fixing the outside of the main deck board is done when installing the auxiliary deck board 10.
Set screw 11 between A and auxiliary deck board 10
It becomes unnecessary because it is fixed at the same time.

The dimensional adjustment of the auxiliary deck board 10 in the width direction is facilitated by tightening and loosening operations from below using the setscrews 11.

(f) In Fig. 4, a mounting screw hole is provided in which the set screw 11 engages with the extension 12b of the U-shaped portion at the right end of the main deck board 12A, and the set screw 11 is inserted at the position where the auxiliary deck board 10 is aligned with the exterior plate B. Attach by.

According to this, the washer 20 shown in FIG.
can be omitted and simplified.

Although the above description has been made regarding escalator balustrades, the same effect can be obtained when applied to passenger conveyor balustrades.

(g) Overall effect As a result of the above, since a large number of outer end main deck boards and auxiliary deck boards that make up the handrails of long escalators and passenger conveyors are used, the number of parts is reduced, the number of processing steps is reduced, and the number of installation steps is reduced. This has the effect of significantly improving productivity and workability in many ways, such as a reduction in man-hours and a reduction in disassembly and adjustment man-hours.
