Abstract

PURPOSE:To improve the safety and the maintenance workability by providing a clearance of space corresponding to extension by expansion previously between adjacent fellow skirt guard panels and mounting a patch of size which protrudes from a reverse side of the one panel to close this clearance. CONSTITUTION:A skirt guard 3 is constituted by mounting a patch 10 to one end and a patch hook 9 to the other end of a panel 2 to successively arrange these panels with a clearance 11. Since the clearance 11 is thus provided previ ously in a connection part of the skirt guard 3, a panel 2 is held between the patch 10 and the patch hook 9 and slid to absorb a change of this sliding even when the clearance 11 is changed by generating swelling and contraction in the panel by hotness and cold accordingly by extending and contracting a length of the panel. By the above-mentioned constitution, the adjacent fellow panels are prevented from being shifted and overlapped by extending the skirt guard panel 2, and irregularity over the total length is prevented from being generated. No gap for foreign matter to intrude is generated in the clearance between the skirt guard panels by the patch 10.

Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an escalator skirt guard.

(Prior Art) A conventional skirt guard will be explained using examples shown in FIGS. 5 and 6.

A skirt guard 3 is formed by arranging a plurality of thin iron plate skirt guard panels 2 adjacent to each other in the longitudinal direction on both sides of an escalator step 1 that is connected in an endless manner and rotates between the upper and lower floors. .

Each skirt guard panel 2 has a hook 4 provided at the lower part of the back surface, and the skirt holder of the parapet frame is inserted into the angle 5, and the upper part of the skirt holder is inserted into the angle 6 and the inner deck board 7.
It is held in place with screws, etc. Adjacent skirt guard panels 2.2 are placed in close contact with each other to prevent passengers' clothes from getting caught and foreign objects from entering, and the surfaces have gaps 8 between them and the steps 1 where passengers' shoes, etc. can be drawn in. A fluororesin coating with a low coefficient of friction is applied to prevent scratches.

(Problem to be solved by the invention) Nowadays, escalators are often installed outdoors, and as the escalators are exposed to direct sunlight, the skirt guard 3 is heated to over 60°C and is made of a thin iron plate. Because of this, a large elongation due to thermal expansion in the length direction may occur.

However, as mentioned above, adjacent skirt guard panels are installed closely together for safety reasons, so this elongation cannot be absorbed, and as a result, unevenness occurs along the entire length of the panel, which causes Contact with the steps may cause abnormal noises, or even one panel may shift and overlap the next panel, causing damage to passengers' shoes, steps, etc.

As a countermeasure against this problem, a gap may be provided in advance between the skirt guard panels to prevent foreign matter from entering, but this may cause the gap to expand when shrinkage occurs due to low temperatures in winter, and foreign matter may enter. Furthermore, adjusting the gap to prevent this will require a lot of time for maintenance work.

The present invention aims to improve the safety and maintenance workability of such escalators.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a gap between adjacent skirt guard panels that corresponds to the elongation caused by expansion, and protrudes from the back side of one of the panels. Attach a patch large enough to close this gap, attach a hook to the other panel, and secure it by sandwiching the patch.

(Function) With this structure, the elongation of the skirt guard panel is absorbed by this gap, and since the plate is sandwiched between the hooks attached to the back of the skirt guard panel, the skirt guard panel will remain in place even when it contracts. It won't come off.

Also, even if the gap becomes large during contraction, the backing plate prevents foreign matter from entering.

(Example) The present invention will be explained based on the example shown in FIGS. 1 to 3.

A caul plate body hook 9 is attached to one back end of the skirt guard panel 2.2, and a caul plate 10 is attached to a position corresponding to the shingle hook 9 on the back side of the adjacent panel. The backing plate body hook 9 is attached to the center part of the upper and lower skirt holders avoiding the angle 5.6, and the backing plate 10 is sandwiched and connected.

In this way, the patch plate 10 is attached to one end, and the patch plate body hook 9 is attached to the other end.
The skirt guard 3 is constructed by arranging them one after another with a gap 11 between them.

In this way, a gap 11 is provided in advance at the connection part of the skirt guard 3.
The panels will expand and contract due to heat and cold.
Therefore, even if its length expands or contracts and the gap 11 changes, the panel 2, held between the caul plate 10 and the caul plate hook, slides and absorbs this change. With the above-mentioned configuration, the elongation of the skirt guard panel 2 will prevent adjacent panels from shifting and overlapping each other, and unevenness over the entire length will not occur.

Furthermore, the backing plate 10 prevents any gaps between the skirt guard panels from allowing foreign matter to enter.

In addition, conventional skirt guard panels were fixed in close contact, one of which was manufactured long in advance, and sometimes cut to fit the actual item during installation, but with this configuration, elongation during expansion has been taken into account. If you decide on the total length including a certain distance or more, there will be no need to cut according to the actual item.

Another embodiment of the invention is shown in FIG.
0 is not provided on the back side of the skirt guard panel 2, and the upper and lower skirt supports of the parapet frame are fixed together with bolts to the angles 5 and 6, and the same effect can be obtained in this way.

〔Effect of the invention〕

According to the present invention, the skirt guard of an escalator installed outdoors can be easily prevented from elongating due to thermal expansion, and can be installed.
Maintenance workability can be improved and safety can be improved.

Claims (1)

[Scope of Claims] A skirt guard for an escalator in which a plurality of skirt guard panels made of thin iron plates are arranged adjacent to each other in the longitudinal direction on both sides of a step, wherein a gap is provided between the adjacent skirt guard panels, and a gap is provided between the skirt guard panels adjacent to each other. This escalator skirt guard is characterized by a backing plate closely fixed to the back side of the panel to close this gap.
