Description

[Detailed Description of the Invention] This invention relates to an improvement of a handrail guide device for a passenger conveyor.

1. A conventional handrail guide device for a passenger conveyor will be explained with reference to FIGS. 1 to 4.

In the figure, 1 is a fixed body made of a truss, and 2 is a flat rod-shaped guide body, which is fixed to the fixed body 1 with a mounting bolt 3.

4 is a handrail of a well-known passenger conveyor, and the return side is engaged with the guide body 2.

Reference numeral 5 denotes a connecting piece provided at the connecting portion of the guide body 2.

That is, the guide body 2 is supported by the fixed body 1 in a suspended state by the mounting bolts 3, and the return side of the handrail 4 is guided by the guide body 2.

However, in order to mount the guide body 2, it is necessary to drill holes for the mounting bolts 3 in accordance with the support position of the guide body 2, and the head of the mounting bolt 3 must be drilled from the bottom surface of the guide body 2. The machining process was complicated in order to prevent this from appearing.

In the past, as shown in FIG. 4, it was difficult to adjust the position of the connecting portion of the guide bodies 2 in the width direction, which caused the guide bodies 2 to be misaligned with each other.

Furthermore, there was also a risk that the holes for the mounting bolts 3 would not be placed in the correct positions, resulting in a gap in the longitudinal direction at the connecting portion of the guide body 2.

In some cases, the connecting portion of the guide body 2 and the position of the mounting bolt 3 may overlap, and in this case, there is a problem that the arrangement of the guide body 2 becomes even more difficult.

This invention solves the above-mentioned drawbacks and aims to provide a handrail guide device for a passenger conveyor in which the guide body can be easily supported on a fixed body at a suitable location.

An embodiment of this invention will be described below with reference to FIGS. 5 to 8.

In the figure, the same reference numerals as in FIGS. 1 to 4 indicate corresponding parts, and 2 is a guide body provided with a longitudinal groove 2a along the longitudinal center of the upper surface;
2b is an opening of the longitudinal groove 2a, and has an opening width narrower than the internal width of the longitudinal groove 2a.

2c is a vertical groove 2 formed to protrude from the upper surface of the guide body 2.
The side wall of a, 6 is an engagement piece that is loosely fitted into the longitudinal groove 2a, T is a contact plate that has a groove-shaped cross section, straddles the opening 2b, and fits on the outer surface of the side wall 2c; A support body consisting of a mounting bolt that is inserted through the plate 7 and screwed into the engagement piece 6, 8 is a nut screwed into the support body 3 and placed in contact with the plate 7, and 9 is an engagement piece. A connecting engagement piece that is arranged in the same way as piece 6 and also serves as a connecting member.The support 3 is screwed into the negative side through the contact plate 7', and the bolt is screwed into the other side through the contact plate 7'. 10 is screwed to engage the end of the guide body 2 with the support body 3, and
Connect the ends of the other guide bodies 2.

Reference numeral 5 denotes a connecting piece, which is arranged in the same manner as the connecting and engaging piece 9, and bolts 10 are screwed and loosened on both sides to connect the ends of the guide body 2 to each other.

That is, the side edge of the opening 2b of the longitudinal groove 2a is the engagement piece 6,
The connecting engagement piece 9, the connecting piece 5, and the contact plates 7, 7' are pressed together, and the guide body 2 is supported by the support body 3 on the fixed body 1 through these, or the guide body 2 is supported by the housing or the guide bodies 2 with each other. is connected.

Since the engaging piece 6, the contact plate 7, etc. can be placed at appropriate positions along the longitudinal groove 2a, the guide body 2 can be easily supported at the corresponding position of the support body 3 attached to the fixed body 1. Can be done.

Moreover, such an effect can be obtained without processing the guide body 2, and it is also possible to eliminate the occurrence of a gap between the guide bodies 2 at the mutual connection portions due to restrictions on the placement location of the support body 3.

In this embodiment, since the contact plate 7 is groove-shaped, the mutual positions of the guide bodies 2 in the width direction are regulated at the connecting portions, so that the guide bodies 2 do not shift from each other in the width direction.

As explained above, this invention provides a vertical groove having an opening narrower than the internal width in the longitudinal direction of the guide body, arranges an engaging piece and abutment in this, and connects the guide body at least through these. To realize a handrail guide device for a passenger conveyor, which can be easily supported at a proper position along the length of the guide body, the manufacturing process is simplified and inexpensive, and the assembly work is also simplified. It is something.
