Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a see-through escalator in which a transparent or semi-transparent exterior panel such as a glass plate is provided on the outer surface of a main frame so that the inside of the main frame can be seen.

0002

2. Description of the Related Art FIG. 3 shows a conventional see-through escalator. In the figure, reference numeral 1 denotes a main body frame generally called a truss or the like, which is installed diagonally between the upper and lower floors 2 and 3 of a building with its both ends hooked. Although not shown, various devices such as steps, their guide rails, and drive devices are installed inside the main body frame 1, and a pair of left and right handrails 4 are erected on the upper side.

[0003] The upper and lower floors 2 and 3 of the main body frame 1
A large number of glass plates 5 as exterior panels are attached to both outer surfaces of the intermediate portion exposed in the space between them, forming a see-through structure through which the inside of the main body frame 1 can be seen. Incidentally, opaque exterior panels 6 made of stainless steel or the like are attached to both outer surfaces of the upper and lower end sides of the main body frame 1, and a bottom plate 7 is attached to the lower surface over the entire length of the main body frame 1.

[0004] Here, the mounting structure of the glass plate 5 is shown in FIG. First, a receiving frame 8 made of square steel pipe is attached and fixed to the inner surface of the side beam 1a of the main body frame 1, and a glass plate 5 is attached to the inner periphery of the receiving frame 8.
are fitted through the glass frame 9, and in this state a presser fitting 10 made of angle material is applied from the inside and screwed. That is, the glass plates 5 are each fitted and fixed to the inner side of the side beam 1a of the main body frame 1 in a roller-like manner.

[0005]

[Problems to be Solved by the Invention] In the conventional see-through escalator described above, each glass plate 5 is fitted and fixed to the outer surface of the main body frame 1 in a roller-like manner, so it is difficult to repair these glass plates 5. When cleaning or cleaning, remove the escalator steps and skirt guards.
In this state, a worker crawls into the main body frame 1 and
It is necessary to reach through the gap between the guide rails and the like from within the main body frame 1 and wipe the back side of the glass plate 5, which requires a lot of setup and difficult work due to unnatural posture. There were drawbacks.

Furthermore, since a large number of glass plates 5 are attached to and supported by the main body frame 1 through the support frames 8, a large load is applied to the main body frame 1, which results in a lack of strength in the main body frame of a general escalator. However, there was a problem in that a specially designed and manufactured body frame 1 was required.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to greatly facilitate the repair and cleaning of exterior panels such as glass plates arranged on the outer surface of the main body frame. To provide a see-through escalator whose main body frame can be designed and manufactured in the same way as a general escalator without considering the load burden of the exterior panel.

[0008]

[Means for Solving the Problems] The see-through escalator of the present invention is provided with an exterior frame supported by the upper and lower floors of a building along the outer surface of a main body frame installed between the upper and lower floors of a building, and this exterior The transparent or translucent exterior panel is provided on the frame so as to be openable and closable, and a locking means is provided to maintain the exterior panel in the open/closed state.

[0009]

[Operation] According to the see-through escalator having the structure of the present invention described above, when repairing or cleaning the exterior panel, the locking means is released and the exterior panel is opened relative to the exterior frame. Repairs and cleaning of the front and back surfaces of exterior panels can be performed very easily from the outside without removing the skirt guard or climbing into the main body frame.

[0010] Furthermore, since this exterior frame is supported on the upper and lower floors of the building separately from the main body frame, the load of the exterior panels is not applied to the main body frame, and the main body frame takes into account the load burden of the exterior panels. Instead, it would be better to design and manufacture it in the same way as a general escalator.

[0011]

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Components in the figure that overlap with those shown in FIGS. 3 and 4 are given the same reference numerals to simplify the explanation.

First, FIG. 1 shows a see-through escalator of the present invention. A large number of glass plates 5 as exterior panels are provided on both outer surfaces of the intermediate portion of the main body frame 11 of this see-through escalator that is exposed in the space between the upper and lower floors 2 and 3.
is attached by means described later, and has a see-through structure through which the inside of the main body frame 1 can be seen.

[0013] Here, the mounting structure of the glass plate 5 is shown in FIG. First, exterior frames 21 are disposed along the longitudinal direction on both outer sides of the side beams 11a of the main body frame 11. This exterior frame 21 is made of channel steel material to form the main body frame 1.
It has a truss-like frame similar to the side beam 11a in No. 1, and its lower end is supported by hanging on the lower floor 2 via a triangular platform-shaped support fitting 22, and the upper end is supported by a support fitting on the upper floor 3. It is latched and supported via 23.

A receiving frame 24 made of a square steel pipe is attached to the back side of the exterior frame 21 with bolts. This receiving frame 24
A triangular glass plate 5 is fitted into the inner peripheral surface of the frame 25 with a glass frame 25 interposed therebetween. Moreover, the glass frame 25 is attached and supported by the receiving frame 24 by a pair of hinges 26, so that the glass plate 5 can be opened and closed. Further, a lock 27 as a locking means is attached to the side opposite to the hinge 26.

A presser metal fitting 28 made of C-shaped channel steel is welded and fixed to the receiving frame 24, and this presser metal fitting 28 is finally attached to the main body frame 1 with bolts.
The main body frame 11 and the exterior frame 21 are temporarily fixed to the side beams 11a of the main body frame 11 to prevent a gap from forming between the body frame 11 and the exterior frame 21.

According to the see-through escalator having the above-described structure, when cleaning the glass plate 5, first, the lock 27 of the glass frame 25 of the exterior frame 21 is released, and the glass plate 5 is removed from the exterior frame 21. , it opens via a hinge 26 . This makes it very easy to repair and clean the front and back surfaces of the glass plate 5 without removing steps or skirt guards or crawling into the main body frame 11 as in the conventional case.

[0017] Also, this exterior frame 21 is connected to the main body frame 11.
Apart from this, the main body frame 1 is supported by a support fitting 22 on the lower floor 2 and a support fitting 23 on the upper floor 3 of the building.
Since the load of this exterior frame 21, receiving frame 24, and multiple glass plates 5 is not applied to 1, the main body frame 11 is designed in the same way as that of a general escalator without considering the load burden of the glass plates 5, etc.・It will get better if you make it.

Furthermore, in the see-through escalator of this embodiment, the glass plate 5 is attached to the transparent exterior panel as the exterior panel.
Although a transparent or translucent material such as an acrylic plate may be used, similar effects can be obtained.

Furthermore, the glass frame 25 is attached via the hinge 26.
Although the glass frame 25 is configured to be openable and closable, substantially the same functions and effects as described above can be obtained even if a handle is provided on the glass frame 25 and the glass frame 25 is configured to be detachable.

[0020]

[Effects of the Invention] Since the present invention is configured as described above, repair and cleaning of the exterior panels such as glass plates arranged on the outer surface of the main body frame can be performed very easily, and the load burden on the exterior panels can be taken into account. It is possible to provide a see-through escalator whose main body frame can be designed and manufactured in the same way as a general escalator without having to do so.
