Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a mounting structure of a skirt guard panel of a passenger conveyor called an escalator or a moving sidewalk.
[0002]
[Prior art]
FIG. 5 is a schematic sectional view showing a mounting structure of a skirt guard panel and a positional relationship with a step in a conventional passenger conveyor. The skirt guard panel 2 is provided on a main frame (not shown) via fixing screws (counterhead screws) 5 and mounting brackets 6 for the angles 3 and 4 so as to be adjacent to the side surface 1 a of the step 1. Supported by The gap H between the skirt guard panel 2 and the steps 1 is kept small so that the feet and clothes of the passengers who get on the steps 1 are not pinched. Reference numeral 1b indicates the tread surface of the step 1.
[0003]
A countersunk hole is formed in the skirt guard panel 2, a screw hole is formed in the angle 3 in accordance with the countersunk hole, and a fixing screw 5 is passed through the screw hole and screwed into the countersunk hole. Thereby, the skirt guard panel 2 is fixed to the angle 3.
[0004]
However, in the above-mentioned conventional structure, when reassembling the skirt guard panel 2 at the time of maintenance or renovation of the passenger conveyor, the countersunk hole of the skirt guard panel 2 and the screw hole of the angle 3 do not match or it is difficult to match. In some cases, this contributes to a decrease in work efficiency.
[0005]
The angle 3 for attaching the skirt guard panel 2 is positioned with reference to the center CL of the passenger conveyor, and is attached to the support member 7 with bolts 7a. In order to enable positioning of the angle 3 with respect to the moving direction of the step 1, the support member 7 has a long hole formed in the moving direction of the step 1.
[0006]
However, in the above-described conventional structure, there is almost no adjustment allowance in the width direction of the step 1 at the angle 3 position, so that adjustment may be difficult or impossible.
[0007]
A guide 9 is provided on the side surface of the step 1 for the purpose of preventing meandering of the step and protecting the skirt guard panel 2. The distance S between the guide 9 and the skirt guard panel 2 is determined by the side surface of the step 1 and the skirt guard panel. The guide 9 may travel while contacting the skirt guard panel 2 during the travel of the steps 1 because the distance H is smaller than the distance H from the skirt guard panel 2.
[0008]
When such an event occurs, since the skirt guard panel 2 is thin, the skirt guard panel 2 is deformed, and the skirt guard panel 2 and the main body of the step 1 come into contact with each other, generating abnormal noise or causing the skirt guard panel 2 to deform. The guard panel 2 may be damaged. Further, there may be a step at the joint between the adjacent skirt guard panels 2, and when the guide 9 collides with the step, abnormal noise may be generated or the guide 9 may be damaged.
[0009]

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a side view showing a main part of an escalator as a passenger conveyor to which the present invention is applied. As shown in FIG. 1, the passenger conveyor has a plurality of steps 1 connected endlessly via a step chain (not shown). The steps 1 circulate between upper and lower floors by a known drive mechanism (not shown). On both sides of the step 1, a plurality of skirt guard panels 10 are arranged continuously along the step moving path.
[0020]
As clearly shown in FIGS. 2 to 4, an angle 11, that is, a mounting member, is welded to the back surface (the surface opposite to the surface facing the step 1) of the upper portion of the skirt guard panel 10. As shown in FIGS. 1 and 4, the angle 11 extends along the moving direction of the steps 1 over substantially the entire length of one skirt guard panel 10. The angle 11 extends continuously and substantially in parallel with the moving direction of the step 1 in a section where the skirt guard panel 10 is provided.
[0021]
The angle 11 is placed on a support member 12 attached to a main frame (not shown), and is fixed to the support member 12 with bolts 13. The support members 12 to which the angles 11 are fixed are provided for each skirt guard panel 10, one each on both sides of the skirt guard panel 10 and one at the center of the skirt guard panel 10. However, only one of the three support members 12 is shown in the drawing.
[0022]
In the angle 11, long holes 11 a long in the moving direction of the steps 1 are formed at positions corresponding to the plurality of support members 12, respectively. The support member 12 has an elongated hole 12 a long in the width direction of the step 1. The angle 11 is fixed to the support member 12 by passing a bolt 13 through the elongated holes 11 a and 12 a and screwing a nut 14 into the bolt 13.
[0023]
A female screw block 15, that is, a nut member is attached to the support member 12 by means such as welding. The female screw block 15 is screwed with a bolt 16a. A nut 16b is screwed into the bolt 16a. The screw 16a is appropriately screwed into the female screw block 15, and then the nut 16b is tightened toward the female screw block 15, whereby the position of the bolt 16a can be fixed.
[0024]
A plurality (four in this example) of hook receivers 17 are attached to the lower portion of the skirt guard panel 10 by means such as welding. On the other hand, the main frame (not shown) is provided with a hook 18 formed by an angle extending along the moving direction of the steps. In the illustrated embodiment, the hook 18 is attached to a support structure that is integral with the support member 12. The hook 18 is inserted into the hook receiver 17 to support the lower part of the skirt guard panel 10.
[0025]
The hook 18 in the form of an angle continuously extends parallel to the moving direction of the step 1 at a height position corresponding to the moving path of the guide 19 provided on the side surface 1a of the step 1. The guide 19 is usually made of resin, and is provided for preventing the meandering of the steps 1 and for preventing the surface of the skirt guard panel 10 from being damaged. According to the arrangement of the hooks 18, even if the guide 19 comes into contact with the surface of the skirt guard panel 10 at any time, the load received by the skirt guard panel 10 due to the contact is received by the hook 18 located on the back side. For this reason, the deformation of the skirt guard panel 10 is suppressed to a minimum. It is preferable to provide a means for adjusting the position of the hook 18 in the step width direction. However, such a position adjusting means may be provided with a long hole in the step width direction in one of the hook 18 and a member supporting the hook 18. It can be realized by providing.
[0026]
As shown in FIG. 4, a step prevention metal fitting 20 is provided at an end of the skirt guard panel 10. The step prevention metal fitting 20 is fixed to the back surface of the skirt guard panel 10 by means such as welding. When the skirt guard panel 10 is assembled at a predetermined position, the step prevention metal fitting 20 projects from the end of the skirt guard panel 10 so as to overlap with the skirt guard panel 10 'adjacent to the skirt guard panel 10. The skirt guard panel 10 'is also provided with a step prevention metal fitting 20'. These step preventing metal fittings 20 and 20 'can prevent a step from being generated between the skirt guard panels even when a load that pushes the skirt guard panels 10 and 10' from the step 1 side is applied. Therefore, generation of abnormal noise and damage to the guide 19 can be prevented.
[0027]
The attachment of the skirt guard panel 10 can be performed according to the following procedure.
[0028]
First, the position of the tip of the bolt 16a is appropriately adjusted by operating the bolt 16a and the nut 16b as a stopper. Next, the hook 18 is inserted into the hook receiver 17, and then the angle 11 is placed on the support member 12, and the angle 11 is attached to the support member 12 using the bolt 13. At this time, the bolts 13 are tightened with a torque of about temporary tightening. Next, while the angle 11 is in contact with the tip of the bolt 16a (see FIGS. 2 and 3), the skirt guard panel 10 is aligned with respect to the step moving direction, and the bolt 13 is tightened with a regular torque. The skirt guard panel 10 is fixed at a predetermined position. The positioning of the skirt guard panel 10 in the step width direction is performed by bringing the angle 11 into contact with the tips of a plurality of bolts 16a (in this example, three bolts 16a are provided for each of the three support members 12). Since it can be performed, the operator only needs to pay attention to the positioning in the step moving direction, so that the work efficiency can be improved and accurate mounting can be performed. By operating the bolt 16a and the nut 16b, fine adjustment after mounting can be performed.
