Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a man conveyer such as an escalator installed on each floor of a building at a slant or a moving walkway installed between remote places of the building,
Especially the structure of the balustrade.

[0002]

2. Description of the Related Art FIG. 2 shows an example of a conventional escalator, in which panels 2 made of, for example, transparent glass material, which are integral with respective deck boards, are erected on both sides of a main body 1 in the width direction. There is. As shown in FIG. 3, a guide frame 4 on which a guide rail 3 is mounted is fitted on the upper portion of the panel 2, and an endless handrail belt 5 is mounted on the guide frame 4 to move for carrying passengers. It is wound so as to travel and move in synchronization with a step (not shown). Here, in order to fit and fix the guide frame 4 on the upper portion 2a of the panel 2, a rubber packing 6 having a complicated shape is press-fitted, and the guide frame 4 is fixed via the rubber packing 6 ( JP-B-55-1224).

FIG. 4 shows the upper structure of the panel 2 having a structure different from that of FIG. 3 above. The upper part of the panel 2 has a guide frame 7 integrally formed with a guide rail portion.
An endless handrail belt 5 is wound around the guide frame 7 so that the handrail belt 5 travels in synchronism with a moving step (not shown) on which a passenger is placed to travel.
Here, in order to fit and fix the guide frame 7 on the upper portion 2a of the panel 2, a mounting body 8 having a reverse trough shape in cross section is fixed to the upper portion 2a of the panel 2 by an adhesive or welding. It is designed to be fixed to the front side by means of a set screw 9 (Jitsuko Sho 62-14061).

Although the escalator has been described above, it has substantially the same structure except that the main body 1 is a frame body that is supported substantially horizontally even on a moving walkway and the moving steps are moving step plates.

[0005]

However, in the above-mentioned balustrade structure of the conventional man conveyor, the former is because the rubber packing 6 having a complicated shape is press-fitted and fixed to the upper portion 2a of the panel 2. The dimensional accuracy of 6 and the thickness accuracy of the panel 2 are important, and the clearance between the thickness of the panel 2 and the fitting portion 4a of the guide frame 4 is processed with high accuracy, and the bending accuracy management of these long objects is also performed. Not only is it required to be strict,
Deterioration of the rubber packing 6 due to aging causes a decrease in fixing force, which reduces reliability and safety and complicates maintenance.

Further, in the conventional balustrade structure of a passenger conveyor, the latter is constructed such that the upper portion 2a of the panel 2 and the fitting portion 7a of the guide frame 7 are attached or welded to each other by a mounting body 8 having a reverse trough shape in section. Since it is fixed and fixed to this mounting body 8 via the set screw 9, the storage management of the adhesive at the installation site, the quality of the bonding work, the safety and hygiene management, etc. become complicated, and the assembly adjustment is not only troublesome. However, there is a problem in that the gripping force and the fixing force are lowered due to deterioration over time, and the reliability and safety are lowered. Further, when the panel 2 is broken, the attachment portion cannot be removed, so that the mounting body 8 cannot be reused, and it is necessary to remanufacture and replace the entire length of the panel 2. It becomes economically disadvantageous.

As described above, all of the conventional ones hold the smooth surface of the glass panel 2 or adopt a fixing means by an adhesive or welding, so that the dimensional accuracy can be maintained and the assembling work can be performed. Not only is it troublesome, but there is a decrease in fixing force due to deterioration over time after assembly, and there is a problem in reliability and safety.

The present invention has been made in view of the above-mentioned circumstances, and its object is to insert the guide frame into the smooth both side surfaces of the panel with high accuracy and to fix the guide frame without using fixing means by an adhesive. An object of the present invention is to provide a balustrade for a man conveyor that maintains a fixing force for a long period of time, and has reliability, safety, and simplification of assembly work.

[0009]

SUMMARY OF THE INVENTION According to the present invention, a panel-shaped member having an inverted U-shaped cross section is inserted into an upper portion of a panel erected on a support frame, and a plate-shaped member is inserted between the panel and the panel and is pressed by a screw from the side. And a handrail belt guide frame body which is fixed to the frame body and which is provided with a sliding contact portion of the handrail belt and is configured to prevent movement due to loosening of screws.

[0010]

[Operation] Since there are no components to be fitted with high precision on the upper part of the panel and no adhesive is used for the fixing means, the assembling work is facilitated, the fixing force can be maintained for a long time, and the reliability and safety are improved. It is also economically advantageous.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a main part of an embodiment of the present invention. In the figure, 2 is a panel similar to the conventional one described above, which is formed of a transparent glass material having a thickness of, for example, about 10 mm, and is integrated with the deck board on both sides in the width direction of the main body 1 shown in FIG. Is erected in The upper portion 2a of the panel 2 is covered with a rubber packing 10 having an inverted U-shaped cross section and a thickness of about 2 mm. The rubber packing 10 has an inverted U-shaped cross section and is, for example, about 3 mm by a roll homing manufacturing method. A rigid frame 11 made of a stainless steel material having a thickness is covered with a gap (about 5 mm) A provided on one side. Then, for example, a strip-shaped sandwich plate 12 having a thickness of about 4 mm made of an aluminum extrusion mold material is inserted into the gap A, and is pressed by the screw 14 screwed into the screw hole 13 of the frame 11, and the panel 2
And the frame 11 is fixed. Here, the length of the screw 14 is dimensioned such that the pressing force required for pinching compresses the rubber packing 10 (a total of about 0.5 mm on both sides). Further, the sandwiching plate 12 is provided with a groove 15 at the center so that the sandwiching plate 12 does not easily fall during the assembly work, and is locked by the tip of the screw 14.

A handrail belt guide frame 16 made of, for example, an aluminum extruded material is attached to the frame 11 fixed through the above-described structure, and a screw hole 17 is formed on the upper surface of the frame 11.
Secure with screws 18 screwed into. The handrail belt guide frame 16 is provided with a downwardly projecting portion 19 on one side, and the inner surface 20 of this projecting portion 19 abuts on the head of the screw 14 that has been tightened to loosen or come out of the screw 14. It is designed to prevent Also, handrail belt guide frame
The guide rails 21 formed beforehand of, for example, a nylon resin material are inserted into the protrusions on both sides of the upper portion of the guide 16. The handrail belt 5 slides on the inner surface of the guide rail 21 and travels.

Although the escalator has been described above, the same can be applied to a moving walkway. However, in the case of a moving sidewalk, the panel 2 is erected on a frame body supported horizontally instead of the main body.

[0014]

As described above, according to the present invention, a combination that does not require particularly precise fitting is used, so that the manufacturing and assembling work of the components is facilitated, and the management and the assembling work are facilitated. Not only is it possible to increase the number of reusable parts even if the panel is damaged by eliminating the need for complicated fixing means such as adhesion, but firmly fixing the handrail belt guide frame to the upper part of the panel for a long period of time. You can
It is possible to provide a balustrade of a passenger conveyor having improved reliability and safety.
