Description

Description: TECHNICAL FIELD The present invention relates to an inner deck of a passenger conveyor, and more particularly to an inner deck suitable for attachment and detachment during inspection and maintenance of the passenger conveyor.

[Prior Art] FIG. 3 is a vertical cross-sectional view showing internal defects of a conventional passenger conveyor.

In FIG. 3, step 1 for moving passengers
The skirt guard 2 is adjacent to the side of the skirt guard 2. The skirt guard 2 is supported by the upper bracket 3 and the lower bracket 4, and the upper end is fixed to the upper bracket 3 by the screw 5. A balustrade 6 is erected on the side of the step 1, and the balustrade 6 is supported by a truss 8 via a balustrade presser 7. And the internal deck 9 covering between the base of these balustrades 6 and the upper part of the skirt guard 2 is
The lower surface of the upper portion is provided with a claw portion 10, and a protrusion portion of the truss 8 is provided in a clearance portion 11 formed by the claw portion 10 and the upper portion of the internal deck 9.
12 mate. On the other hand, the lower part of the inner deck 9 is fixed to the skirt guard 2 by a screw 16 inserted into holes 13 and 14 penetrating the lower part and the upper part of the skirt guard 2 and screwed into screw holes 15 provided in the upper bracket 3. It is fixed to the upper bracket 3 via.

In order to remove the inner deck 9 having such a structure for inspection and maintenance of the passenger conveyor, first loosen the screw 16 that is screwed into the screw hole 15 of the upper bracket 3 and then remove it. By pulling the deck 9 toward the step 1, the clearance 11 can be removed from the protrusion 12 of the truss 8. In addition, after inspection and maintenance, etc., to mount the inner deck 9 again, after fitting the clearance 11 to the protrusion 12 of the truss 8, the position of the hole 13 of the upper deck 9 is changed to the hole of the skirt guard 2. 14 and upper bracket 3
Align the screw holes 15 with the screws 16 in these holes 13, 14
It is adapted to be screwed into the screw hole 15 after being inserted into.

A device related to this type of device is, for example, the one shown in Japanese Utility Model Laid-Open No. 57-155173.

[Problems to be solved by the invention]

By the way, in the case of the above-mentioned conventional passenger conveyor inner decking, when carrying out desorption for inspection and maintenance of the passenger conveyor, misalignment such as holes 13 occurs each time this desorption is repeated, but in this state If you forcibly attach the screw 16,
16 and the screw part of the screw hole 15 will be damaged, so with this,
There was a problem that the screw 16 was loosened by the vibration during the operation of the passenger conveyor, and the passenger's clothes and belongings were caught on the head of the screw 16 protruding above the step 1.

The present invention has been made in view of such circumstances in the prior art, and an object thereof is to provide an inner deck of a passenger conveyor without providing a mounting screw in the vicinity of a step.

[Means for solving problems]

In order to achieve this object, the present invention relates to an inner deck of a passenger conveyor which covers between an upper portion of a skirt guard adjacent to a side portion of a step and a base portion of a balustrade standing upright on the side portion of the step. The upper part of the skirt guard and the upper bracket for supporting the upper part of the skirt guard are provided with projections that fit into the holes respectively drilled, and the upper part is provided with a mounting part screwed to the base of the balustrade. It has a configuration provided.

[Action]

Since the present invention is configured as described above, the protrusion provided on the lower portion of the inner deck fits into the holes formed in the skirt guard and the upper bracket, respectively, and is provided on the upper portion of the inner deck. The mounting portion is screwed onto the base of the balustrade. As a result, the inner deck can be easily mounted without providing a mounting screw on the lower portion of the inner deck disposed near the step. Therefore, the accident of catching the clothes of passengers does not occur due to the removal of the screws for mounting the inner deck.

〔Example〕

The internal defects of the passenger conveyor of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 are explanatory views showing an embodiment of the inner deck of the passenger conveyor of the present invention. FIG. 1 is a longitudinal sectional view showing the entire structure, and FIG. 2 is a structure of part A of FIG. FIG. In addition, in FIG. 1 and FIG.
The same parts as those shown in the figure are designated by the same reference numerals.

In FIG. 1, the base of the balustrade 6 and the skirt guard 2
The inner deck 20 that covers the upper part of the
A protrusion 21 is provided on the side opposite to, and a mounting portion 22 supported by the truss 8 and fixed by a screw 23 is provided on the upper portion. A joint rubber 24 covers the upper portion of the mounting portion 22.

Next, referring to FIG. 2, the protrusion 21 provided on the lower portion of the inner deck 20 is fitted into the holes 25 and 26 respectively formed in the skirt guard 2 and the upper bracket 3 via the cushioning material 27. There is.

In this embodiment, in order to remove the inner deck 20 for inspection and maintenance of the passenger conveyor, first, the joint rubber 24 shown in FIG. 1 is removed, and the screw 23 is loosened and removed. Next, the protrusion 21 is pulled out from the holes 26 and 25 by pulling the inner deck 20 toward the step 1. In this way, the inner deck 21
Can be removed. Also, after inspection and maintenance,
To reattach the inner deck 20, insert the protrusion 21 at the bottom of the inner deck 20 into the holes 25 and 26 and fix the upper mount 22 with the screw 23 in the reverse order of removal. A joint rubber 24 covers the upper part of the portion 22.

〔The invention's effect〕

Since the inner deck of the passenger conveyor of the present invention is configured as described above, the inner deck can be easily mounted without providing a mounting screw on the lower portion of the inner deck disposed near the step. Therefore, there is an effect that it is possible to prevent an accident in which a passenger's clothes or the like are caught by the removal of the mounting screw of the inner deck.
