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.

Recently, most of the balustrades 2 of such a man conveyer have a slim shape with enhanced transparency, and the construction thereof is arranged on a main frame (not shown) called a truss as shown in FIG. A plurality of transparent balustrade panels 4 such as glass panels, which are arranged upright, are mounted on the balustrade panels 4 via an elastic material 5 having an inverted U-shaped cross section, which is called a rubber packing or the like. And a handrail deck 6 for movably guiding and supporting.

The handrail deck 6 has a substantially inverted U-shaped cross section composed of a top plate portion 6a and inner and outer side plate portions 6b and 6c.
The upper part of the balustrade panel 4 has a groove 7 which is continuously inserted in a longitudinal direction in a state where the upper part of the balustrade panel 4 is covered with the elastic member 5, and the flange parts 6d are projected on both inner and outer sides on the top plate part 6a. A low friction member 8 made of synthetic resin or the like is fitted to these to form the guide rail portion of the moving handrail 3.

Here, the groove 7 of the handrail deck 6 is formed with an inclined surface 7a inside the groove 7, that is, inside the outer plate portion 6c so that the groove width becomes narrower as it goes upward.
A plurality of substantially wedge-shaped fastening members 9 are provided in the groove 7 at appropriate intervals in the longitudinal direction so as to be vertically movable along the inclined surface 7a. Screw holes 9 for each of these tightening materials 9
By screwing a screw 10 loosely inserted on the top plate portion 6a of the handrail deck 6 into a, and tightening the screw 10 to raise the fastening member 9 along the slope 7a in the groove 7, The fastening member 9 generates lateral pressure, and the balustrade panel 4 via the elastic member 5.
The handrail deck 6 is attached and fixed in a state of being fitted on the balustrade panel 4 by strongly pressing the upper part of the handrail so as to be sandwiched in the groove 7.

[0007]

By the way, in the balustrade of the conventional man conveyor mentioned above, the tightening material 9 in the groove 7 at the lower part of the handrail deck 6 is lifted along the slope 7a by tightening the screw 10. By doing so, the lateral pressure generated in the tightening material 9 presses and fixes the upper part of the balustrade panel 4 in the groove 7 via the elastic material 5, but when the tightening material 9 is tightened, the tightening material 9 is tightened. Since the attachment material 9 rises while directly contacting the elastic material 5, the elastic material 5 may be flipped up, and the fastening material 9 may not be able to press and fix the upper part of the balustrade panel 4 appropriately. For this reason, the work of assembling the balustrade was troublesome, for example, the work of tightening the fastening material 9 had to be done carefully.

The present invention has been made in view of the above circumstances,
The purpose is that even if the fastening material is tightened along the slope in the groove of the handrail deck and moved up and down while generating lateral pressure, the elastic material covered on the upper part of the balustrade panel is flipped up. The present invention is to provide a balustrade for a man conveyor that allows the upper part of the balustrade panel to be pressed and fixed so as to be properly sandwiched in the groove of the handrail deck, which makes the assembly work very easy.

[0009]

In order to achieve the above object, the balustrade of a passenger conveyor of the present invention is provided with a groove into which a balustrade panel upper part is covered with an elastic material at the bottom of a handrail deck, and A state in which a slope is formed on one side in the groove, and it is arranged so as to be movable up and down along the slope in the groove, and lateral pressure is generated by tightening to clamp the upper part of the balustrade panel into the groove via the elastic material. It is characterized in that a tightening member for pressing is provided, and a contact plate is further provided between the tightening member and the elastic member.

[0010]

According to the balustrade of the man conveyer having the above-described structure, when the balustrade is assembled, the fastening material in the groove under the handrail deck is tightened and raised along the slope, and the fastening material is applied to the backing plate. Lateral pressure is generated while slidingly contacting to press the corresponding plate, and thereby the upper part of the balustrade panel is pressed and fixed in a state of being sandwiched in the groove via the elastic material. For this reason, since the fastening material does not directly contact the elastic material, the elastic material does not turn up or slip off, and the fastening material can be accurately pressed and fixed on the upper part of the balustrade panel, and the balustrade assembly work can be performed. Smooth and easy.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. In the figure, the same components as those in FIGS. 2 and 3 described above are designated by the same reference numerals to simplify the description.

First, in the same manner as in the prior art, an elastic member 5 such as a rubber packing having an inverted U-shaped cross section is covered on the upper part of the balustrade panel 4 which is vertically provided. On the other hand, the handrail deck 6 is a long one made of extruded aluminum material, and has a substantially inverted U-shaped cross section composed of a top plate portion 6a and inner and outer plate portions 6b and 6c.
A groove 7 having a beveled surface 7a at the bottom is formed continuously in the longitudinal direction, and the upper part of the balustrade panel 4 covered with the step constellation 5 is inserted into the groove 7.

A plurality of substantially wedge-shaped tightening members 9 are provided in the groove 7 at appropriate intervals in the longitudinal direction, and each of the slanted faces 7 is formed.
A screw 10 is provided so as to be vertically movable along a, and 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.

A contact plate 20 is provided between the tightening member 9 and the elastic member 5 in the groove 7. The abutting plate 20 is a thin plate made of stainless steel or the like bent in an inverted L-shaped cross section, and hangs down with the upper horizontal plate portion 20a in contact with the lower surface of the top plate portion 6a (the upper surface of the groove 7) of the handrail deck 6. The plate portion 20b is provided so as to be arranged between the tightening member 9 and the elastic member 5. The upper horizontal plate portion 20a is provided with a hole 21 into which the screw 10 is loosely inserted.

When the screw 10 is tightened, the tightening member 9 rises along the sloped surface 7a in the groove 7 to generate a lateral pressure,
With this, the hanging plate portion 20b of the pad plate 20 is pushed, and the upper portion of the balustrade panel 4 is strongly pressed so as to be sandwiched between the upper portion of the balustrade panel 4 and the inner side plate portion 6b in the groove 7 by the elastic material 5, so that the handrail deck 6 is attached and fixed so as to be fitted on the balustrade panel 4. Reference numeral 22 in the drawing denotes the outer side plate portion 6c of the handrail deck 6.
The cover portion integrally extending from the lower end to the groove 7 side covers the fastening material 9 in the groove 7 from below.

However, according to the balustrade of the man conveyer having the above-mentioned structure, when the balustrade is assembled, the groove 7 under the handrail deck 6 is formed.
Even if the tightening material 9 in the inside is lifted up along the slope 7a by tightening the screw 10, the tightening material 9 slides the contact plate 20 to generate a lateral pressure and pushes the corresponding plate 20. Since the upper part of the balustrade panel 4 is pressed and fixed through the elastic member 5 in a state of being sandwiched in the groove 7, the tightening member 9 does not directly contact the elastic member 5, so that the elastic member 5 is turned up. There is no deviation, and the upper part of the balustrade panel 4 can be properly pressed and fixed by the fastening material 9, so that the balustrade assembly work is smooth and easy. Incidentally, the balustrade of the man conveyor of the present invention is not limited to the above-mentioned drinking example,
For example, the contact plate 20 may be a flat plate other than the inverted L-shaped cross section.

[0017]

Since the balustrade of the passenger conveyor of the present invention is constructed as described above, even if the fastening material is tightened along the slope in the groove of the handrail deck to generate lateral pressure, the balustrade is moved up and down. The elastic material covering the upper part of the balustrade panel does not flip up or slip off, and the upper part of the balustrade panel can be pressed and fixed so as to be properly sandwiched in the groove 7 of the handrail deck, which makes the assembling work very easy.
