Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a passenger conveyor such as an escalator or an electric road, and more particularly to a balustrade for a passenger conveyor in which the balustrade panels are arranged vertically.

[Conventional technology]

In general, there are two types of balustrade configurations for passenger conveyors: one in which the balustrade panel is made of transparent glass, and the other in which the balustrade panel is made of opaque metal plate. In the former method, as shown in Japanese Patent Application Laid-open No. 52-61085, the parapet panels are arranged almost vertically so as to ensure sufficient space near the steps. On the other hand, the latter is published in Utility Model Application Publication No. 8686/1986,
Publication No. 116680, Publication No. 51-158588, Publication No. 158588, Publication No. 158588, Publication No. 158588
As shown in Japanese Patent Application No. 52-56887 and Japanese Patent Application Laid-open No. 59-118683, the balustrade panels are arranged at an angle so that the distance between the balustrade panels narrows near the steps, and this configuration is shown in Fig. 4. ing.

The figure shows a longitudinal section of the parapet 6, and the main frame 1
The lower end of a column 11 is fixed on top of the column 11, and a main deck 3 supporting a movable handrail 2 is fixed on the upper part of the column 11. Between this main deck 3 and the scard guard 5 provided on the side of the step 1, there is a parapet panel 4.
is located. The upper end of the balustrade panel 4 is fixed to the pillar 11 via the support 7, and the lower end is supported to the scaffold guard 5 by long supports 8 and 9 arranged over the entire length of the step 1 in the direction of movement. The support portion is covered with an inner deck 15 for decoration.

[Problem that the invention seeks to solve]

Since the parapets of conventional passenger conveyors had the above-mentioned configuration, the space W below between the pair of parapets 6
is narrow. For this reason, there is a demand for arranging the balustrade panel 6 almost vertically as shown by the two-dot chain line P in FIG. However, considering the general support structure of the balustrade panel 6 in this case, as shown by the dotted line in the same figure, there is a support P _c welded to the pillar 11 and a fixing support P provided at the lower end of the balustrade panel 6. _b , and a support that fixes the lower part of the parapet panel 6 to the support P _c
P _a is required. These supports P _a , P _b and
Like the conventional supports 8 and 9, P _c is long in the running direction of step 1, making it heavy, and its shape is curved in the longitudinal direction, making it difficult to manufacture.
There was a problem that assembly efficiency was reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a balustrade for a passenger conveyor in which the supporting structure of a substantially vertical balustrade panel is robust and simple, thereby increasing assembly efficiency.

[Means for solving problems]

In order to achieve the above object, the present invention has a balustrade panel arranged almost perpendicularly between the main deck and the inner deck, and a plurality of balustrade panels divided in the direction of progression of the steps, and a plurality of balustrade panels arranged in the direction of progression of the steps. A post is arranged at the joint between the steps, and a fixing piece provided at the lower end of the parapet panel so as to protrude toward the step side is placed on the support piece fixed to the post and fixed by a fixing means, and the fixing piece and the support piece The fixing part including the fixing means is covered by the inner deck.

[Effect]

Since the balustrade of the present invention has the above-described configuration, it is possible to widen the space below the balustrade panels by arranging the balustrade panels almost vertically. Since only the joints in the advancing direction of the steps are needed, the step does not have to be long like the conventional one, is lightweight, and does not have the manufacturing difficulties associated with curving, thereby improving assembly efficiency. Also,
Since the lower end of the balustrade panel is firmly supported by the fixing means, even if a passenger presses on the balustrade panel, the balustrade panel will not bend and come off the fixed piece, improving the reliability of the balustrade panel support. will improve.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a longitudinal section of a parapet located on one side of the step 1. The main deck 14 supports a movable handrail 2 on the top of a column 13 whose lower end is fixed to the main frame 10. is fixed in the same configuration as before. However, the handrail panel 12 arranged between the inner deck 15 and the main deck 14 on the step 1 side is substantially vertical, which is different from the conventional one. Balustrade panel 1
The upper part of 2 is supported by a packing 17a fitted to the main deck 14 and a packing 17b fitted to a support 16 attached to the column 13. On the other hand, at the lower end of the parapet panel 12, there is a fixed piece 12 that is manufactured as an integral part or separately and then welded.
A is bent so as to protrude toward the step 1 side. Support piece 1 for mounting and fixing this fixing piece 12a
3a is fixed to the support column 13 by welding or the like. A screw 1 is connected between the support piece 13a and the fixed piece 12a.
8, and at this time, the screw 18 also tightens the metal fitting 19. A packing 20 is held by this metal fitting 19, and one end of the inner deck 15 is held by this packing 20. The other end of the inner deck 15 is fixed to the card guard 5.

The support structure for the lower end of the above-mentioned balustrade panel 12 will be explained in more detail with reference to FIG. 2. The balustrade panel 12 is made up of a plurality of pieces divided in the direction of movement of the step 1, and a support 13 is arranged at the joint. Seat-shaped support pieces 13a are welded to each of the pillars 13, and two holes A are formed in each of these support pieces 13a.
is formed. At the lower end of the balustrade panel 12 placed between the pair of support pieces 13a, there is a fixed piece 12a that protrudes toward the step 1 side, and at the end of the fixed piece 12a, one of the holes A of the support piece 13a is located on the opposite side. A hole B is formed that matches the . In this way, the dimension l between the pillars 13 is made approximately equal to the length L of the balustrade panel 12 along the step advancing direction.

By aligning the joint portion of the balustrade panel 12 in the step progression direction with the position of the support post 13, it is possible to use a support piece 13a with a small length along the step progression direction, which is similar to the conventional configuration. It is possible to significantly reduce the weight compared to the case where a long object that is continuous in the direction is used. Furthermore, although the passenger conveyor has a curved end in the direction of step progression, since the length of the support piece 13a along the direction of step progression is small, the bending operation is extremely easy. Furthermore, the support of the balustrade panel 12 is strong, and the balustrade panel 12 does not bend and come off even if pushed by a passenger, so the reliability of the support is improved despite the simple structure.

Next, the connection structure between the fixed piece 12a and the support piece 13a will be explained using FIG. 3.

When the screws 18 are screwed into the holes of the fixed piece 12a and the support piece 13a, the metal fittings 19 are also tightened. This metal fitting 19 holds a packing 20 having a substantially E-shaped cross section.The back side of the packing 20 is placed on the handrail panel 12, the recess side is set as the step 1 side, and the metal fitting 19 is inserted into the recess at the bottom. Then, the packing 20 is fixed. One end of the inner deck 15 is fitted into the recess above the packing 20 that is not used for fixing, and the one end of the inner deck 15 is fixed by the elastic force of the packing 20 or the like. The column 13 side of the balustrade panel 12 can also be held by screwing metal fittings Z provided as needed to the support piece 13a.

Since the inner deck 15 is fixed using the connecting structure of the fixing piece 12a and the supporting piece 13a in this way, the structure can be simplified. Furthermore, by using the packing 20, metal-to-metal contact between the inner deck 15 and the balustrade panel 12 can be avoided, a buffering effect can be obtained, and the inner deck 15 can be supported easily. Furthermore, since the support part is covered by the inner deck 15, the support part is not exposed to the passengers' eyes.

In the above embodiment, the struts 13 are arranged only at the joints of the balustrade panels 12, but any structure may be used as long as the struts 13 are provided at least at the joints.
Further, although the fixed piece 12a is formed continuously between the pair of supporting pieces 13a, it may be formed only in the portion corresponding to the supporting piece 13a.

〔Effect of the invention〕

As explained above, in the present invention, a balustrade panel is arranged almost vertically, a fixing piece is provided at the lower end of the balustrade panel that protrudes toward the step, and a support piece is provided on a post provided at a joint in the balustrade panel in the direction of step movement. , because the fixed piece was placed on this support piece and fixed,
The support piece can be shortened to make it lighter and easier,
Therefore, the supporting structure of the balustrade panel can be made robust and simple, and assembly efficiency can be increased.
