[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a balustrade of a man conveyor such as an escalator and a moving walkway.

[0002]

2. Description of the Related Art Generally, a man conveyor such as an escalator or a moving walkway is arranged in the shape of an endless conveyor as shown in FIG. And a balustrade 2 standing upright on both outer sides thereof, and a moving handrail 3 slidably fitted on the balustrade 2 and rotationally driven in synchronization with the step 1.

In recent years, most of the balustrades 2 of such a man conveyer are slim type with improved transparency, and the structure thereof is a main frame called truss (not shown) as shown in FIGS. 5 to 7. A plurality of transparent balustrade panels 4 such as glass panels, which are arranged in a row in an upright manner, are mounted on the balustrade panels 4 via elastic members 5 such as rubber packing, and the movable handrail 3 is movably guided. It is provided with a handrail deck 6 for supporting.

Here, the handrail deck 6 has a top plate portion 6a.
And a groove 7 into which the upper part of the balustrade panel 4 is inserted in the lower part, which has a substantially inverted U-shaped cross section composed of the inner and outer plate parts 6b, 6c.
Is continuously provided in the longitudinal direction. In addition, on the top plate portion 6a, there is a collar portion 6d integrally protruding on both inner and outer sides,
A low-friction member 8 made of synthetic resin or the like is fitted on these to form the guide rail portion of the moving handrail 3.

The groove 7 of the handrail deck 6 is formed with a slope 7a on the negative side of the groove 7, that is, on the inner side of the outer plate portion 6c so that the groove width becomes narrower as it goes upward. A plurality of tightening members 9 are provided in the groove 5 so as to be vertically movable along the slope 7a. Each of these fastening members 9 is arranged at a pitch of about 400 mm in the longitudinal direction of the balustrade panel 4, each has a short rod shape of about 100 mm and has a wedge-shaped cross section, and each has two screw holes 9a. Are formed so as to penetrate vertically.

A screw 10 loosely inserted from above the top plate portion 6a of the handrail deck 6 is screwed into the screw hole 9a of each of the fastening members 9, and the fastening member 9 is tightened by tightening the screw 10. By ascending along the sloped surface 7a in the groove 7, the tightening member 9 generates lateral pressure and strongly presses the upper end of the balustrade panel 4 into the groove 7 via the elastic member 5. Then, the handrail deck 6 is fixedly attached to the balustrade panel 4 in a fitted state.

After fixing the handrail deck 6 to the balustrade panel 4 by tightening the fastening material 9, the groove 7 of the handrail deck 6 is fixed.
A cover 11 is attached and fixed by a screw 12 to cover the fastening material 9 in the lower opening.

By the way, in the balustrade of the above-mentioned conventional man conveyor, after fixing the handrail deck 6 on the balustrade panel 4 by tightening the fastening material 9, the handrail deck 6 of the handrail deck 6 is fixed. A cover 11 for covering the fastening material 9 is attached to the opening of the lower surface of the groove 7 by a screw 12, but the cover 11 must be fixed by the screw 12 from the lower side of the handrail deck 4. Is poor, it takes a long time to complete the installation, and the number of parts is large. Further, since the cover 11 is screwed to the tightening member 9, the tightening of the tightening member 9 with the screw 10 causes The height of the cover 11 fluctuates and a step is formed between the lower end of the handrail deck 6 and the like, so that the cover 11 does not look good and has poor design due to a mounting defect.

Further, in the balustrade of the above-mentioned man conveyor, the handrail deck 6 is fixed to the upper part of the plurality of balustrade panels 4 which are individually erected by tightening the tightening material 9, but each tightening is performed. Since the attachments 9 are arranged at a pitch irrelevant to the seam X of the balustrade panel 4 and the seam Y of the handrail deck 6 as shown in FIG. 5, each balustrade panel 4 is left and right (inward and outward of the man conveyor). When the handrail deck 6 is fitted on the upper part of the balustrade panel 4 and tightened and fixed by the tightening member 9, as shown in FIG. The step of the seam portion X of the balustrade panel 4 is not eliminated, and the seam portion Y of the handrail deck 6 also has a step, so that the appearance is very bad. For this reason, when each balustrade panel 4 is erected, much effort is required to adjust the left and right tilts of the balustrade panel 4 in order to eliminate the step of the seam portion X thereof.

The present invention has been made in view of the above circumstances, and its first
The purpose is to eliminate the work of attaching the cover to the bottom surface of the handrail deck at the time of assembling the balustrade, which can reduce the number of parts and labor of the assembling work, and at the same time the design can be improved at a very low cost. To provide a good man conveyor balustrade.

A second object is that even if the work of tilting left and right when the balustrade panel is erected can be easily done, if the handrail deck is tightened and fixed to the upper part of the balustrade panel, the seam portion of the balustrade panel is fixed. It is an object of the present invention to provide a balustrade of a man conveyor which is capable of eliminating the step and the step of the seam portion of the handrail deck, and which is extremely excellent in assembling workability and design.

The interior is fully covered and the cover is formed integrally with the handrail deck, so there is no problem such as mounting steps due to screwing like the conventional cover, and the design can be improved. ..

In the balustrade of the passenger conveyor of the second invention, a groove is formed in the lower part of the handrail deck into which the upper part of the balustrade panel is inserted, and a slope is formed on one side of the groove, and along the slope of the groove. A fastening member is provided which is arranged so as to be movable up and down and which generates a lateral pressure by tightening to press the upper part of the balustrade panel into a groove by means of an elastic material. It is characterized in that it is arranged so as to straddle the parts, and that the two balustrade panels on both sides of the joint are pressed together by this fastening material.

As described above, while the balustrade panel is erected in the same manner as described above, the handrail deck having the fastening material arranged in the groove is fitted over the balustrade panel, and the fastening material is tightened. When the handrail deck is attached and fixed so that the upper part of the panel is sandwiched by the elastic material, the balustrade assembly work is completed. here,
The fastening material is arranged so as to straddle the joint portion of the balustrade panel, and the two lateral balustrade panels on both sides of the joint portion are pressed together by the lateral pressure due to the tightening of the fastening material, so that the balustrade panels face each other. As a result, the steps are forcibly eliminated, and the steps at the joints of the handrail decks attached to the upper parts of the balustrade panels are also eliminated. As a result, it is possible to easily complete the work of adjusting the left and right tilts when the balustrade panel is erected, and it is possible to improve the assembly workability and the design.
