Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to improvements to handrails for passenger conveyors such as escalators, moving walkways, and the like.

Conventional passenger conveyor balustrades are shown in FIGS. 1-3.

In the figure, 1 is a truss of a passenger conveyor, which is generally made of angle iron. 2 is a treadboard, and 3 is an inner board that is placed on the side of the treadboard 2 in a row along the treadboard 2, and is usually made of 12mm thick transparent tempered glass for manufacturing and transportation reasons. The length of each sheet is approximately 700 to 2,500 mm. 4 is a fixture for fixing the inner plate 3 to the truss 1, 5 is a packing made of soft plastic, 6 is a handrail frame made of extruded aluminum material, 6a is a groove provided at the bottom of the handrail frame 6, 6b ~6d is groove 6a
6e is a handrail guide rail formed on the top of the handrail frame 6; 7 is a bolt screwed into the peripheral wall 6d and whose head is disposed in the groove 6a; 8 is a movement guided by the handrail guide rail 6e. handrail,
9 and 10 are the decks of the parapet, and 11 is the exterior plate of the passenger conveyor.

That is, the fixture 4 is attached to the truss 1, and the lower edge of the inner plate 3 is inserted and fixed therein. after that,
The upper edge of the inner plate 3 is covered with packing 5, which is inserted into the groove 6a of the handrail frame 6, and the head of the bolt 7 is turned to press and fix the inner plate 3 to the side wall 6b.

However, since the fixture 4 and the inner plate 3 themselves have production distortions such as deformation and curvature, and because multiple parts are provided, it is impossible to assemble the parts without disrupting their mutual relationships. . Therefore, when the inner plate 3 is completely erected, it is difficult to expect the upper edges to be aligned in a straight line, and usually the third
As shown in the figure, they shift and become misaligned.

Now, for reasons of assembly and strength, the handrail frame 6 is formed in an elongated dimension that is several times as long as the inner plate 3, making it difficult to handle. That is, since the length of the handrail frame 6 is not equal to the length of the inner plate 3, when the handrail frame 6 is attached to the upper edge of the inner plate 3, there is a gap between the packing 5 and the side wall 6d due to the shift of the inner plate 3. Since A is smaller than the height H of the head of the bolt 7, it is not easy to attach the long handrail frame 6 to the inner plate 3. In addition, when assembling the handrail frames 6 by sequentially abutting each other so that the end faces of the handrail frames 6 do not shift from each other and form a step, gaps are created between the abutting surfaces. To prevent this,
To attach one handrail frame 6, it is necessary to repeatedly attach and detach the long handrail frame 6 more than ten times and file the end faces together. Further, it is necessary to tighten or loosen the bolt 7 each time, which requires a large amount of time, and the efficiency of the assembly work is extremely poor. Further, the wall thickness of the peripheral walls 6b to 6d of the handrail frame 6 is required to be 6 to 8 mm, which requires a large amount of aluminum and makes the product expensive.

The present invention aims to improve the above-mentioned drawbacks, and aims to provide a handrail for a passenger conveyor in which the inner panels can be easily aligned to improve assembly work efficiency, and the handrail frame can be made lightweight and constructed at low cost. do.

An embodiment of the present invention will be described below with reference to FIGS. 1, 4, and 5.

In the figure, reference numeral 12 denotes fasteners provided at the upper edge and intermediate portion of the joint between the inner plates 3, which are manufactured from steel by forging, casting, or hot extrusion. The length of one piece is
It is 200-300mm. 12a is a groove provided in the lower part of the fastener 12, 12b to 12d are peripheral walls forming the groove 12a, and 13 is a handrail guide with a handrail guide rail 6e formed in the upper part and a lower part covering the upper surface and both sides of the fastener 12. Then, tighten the fastener 1 with the screw 14.
It is fixed to 2.

Note that the inner plate 3, fixture 4, etc. are the same as those shown in FIG.

After the inner plates 3 are erected and arranged as explained in FIG.
2 and fix it to the inner plate 3 with bolts 7 as in the case of FIG. The inner plates 3 are now aligned substantially in a straight line. Since the fastener 12 is small,
Attachment to the inner plate 3 is extremely easy. Fastener 1
2. Once you put it on, you don't have to take it off again. When the attachment of the fastener 12 is completed, the handrail guide 13 is placed on it. The work of grinding together the end faces when assembling the handrail guide can be done by simply repeatedly placing the fastener 12 on top of the fastener 12, and there is no need to tighten or loosen the bolt 7.
Assembly work efficiency is significantly improved. The upper surface of the fastener 12 is a part on which a handrail guide 13 can be placed, and the width of this placement part and the handrail guide 13
As shown in FIG. 4, the inner width of the U-shaped portion on the lower surface of the handrail guide 13 is almost the same, and the inner shape of the handrail guide 13 and the mounting portion match. Handrail guide device 13 for the work described in
When temporarily lying down on the fastener 12, the position of the handrail guide 13 is always defined by the fastener 12 and remains constant, and the handrail guide 13 can be stably placed and held on the placement part. After completing the above-mentioned grinding work, screw the handrail guide 1 with the screw 14.
3 to the fasteners 12, the parapet assembly work is completed. Since the handrail guide 13 is not provided with bolts 7, it does not need to be strong. Therefore, the wall thickness of the portions corresponding to the peripheral walls 6b and 6c in Fig. 2 can be made thinner, and the peripheral wall 6d is not required, making it lightweight and easy to attach and detach during assembly, reducing the physical burden on the worker. Ru. Furthermore, since the part of the handrail guide 13 that covers the fastener 12 does not need to be strong, not only aluminum extrusion but also plastic extrusion, wood, etc. can be used, and thin sheet metal made by pressing or roller forming method can be used. can also be used. Therefore, the degree of freedom in designing the railing of the passenger conveyor increases.

As explained above, in this invention, a fastener is provided on the upper edge of the inner side plates arranged in parallel, and the upper surface of the fastener is placed on a mounting surface having a shape that overlaps with a portion covering the upper edge of the inner side plate of the movable handrail guide. As a result, the movable handrail guide can be stably held in a constant position with respect to the fastener when temporarily lying down. As a result, the end face milling work when assembling a long handrail guide can be performed efficiently.
