Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an in-tower cable holding device provided in an elevator hoistway.

[Conventional technology]

Figures 3 to 5 are explanatory diagrams showing an example of a conventional in-tower cable holding device. Figure 3 is a perspective view of the main part as seen from the hoistway toward the landing door, and Figure 4 corresponds to Figure 3. FIG. 5 is an enlarged explanatory diagram showing the cable attachment part.

In these Figures 3 and 4, 1 is a hoistway, 2 is a guide rail installed in this hoistway 1, 3 is a landing door, 4 is a pocket that supports this landing door 3, and 5 is a landing door. The landing door 3, the pocket 4, the push button device 5, etc. constitute a landing device 6. 7 is an intra-tower cable extending into the hoistway 1; 8 is a bracket fixed to the guide rail 2 to hold the intra-tower cable 7; 9 is the tip of the intra-tower cable 7; , is connected to the hall device 6, for example, the push button device 5. Reference numeral 10 denotes a metal fitting for fixing this tip portion 9 to the wall of the hoistway 1. Also, in Figure 5, 11
is a hole drilled in the hoistway 1 wall, 12 is this hole 11
The sleeve 13 is a screw that is screwed into the sleeve 12, and the screw 13 connects the metal fitting 8.
The tip end portion 9 is fixed to the wall of the hoistway 1 via.

Additionally, related devices of this type include:
Examples include those shown in Utility Model Application Publication No. 53-13764 and Japanese Patent Application Publication No. 59-74878.

[Problem that the invention attempts to solve]

By the way, in the conventional in-tower cable holding device described above, the bracket 8 for holding the in-tower cable 7 is arranged near the guide rail 2. The tip 9 of the intra-tower cable 7 that is routed along the tower is required to be long, and therefore, together with the metal fittings 10 that fix the tip 9 at predetermined distances, the metal fittings drilled into the wall of the hoistway 1 are required. There was a problem that many holes 11 for 10 were required, and it took a lot of work time to install the push button device 5 and the like.

The present invention was made in view of the actual situation in the prior art, and its purpose is to shorten the length of the tip of the in-tower cable that is routed along the hoistway wall to the landing equipment. An object of the present invention is to provide an in-tower cable holding device.

[Means for solving problems]

In order to achieve this object, the present invention provides an in-tower cable holding device having a bracket for fixing an in-tower cable, which is installed in an elevator hoistway and whose tip end connects to a hall device, to the hoistway wall. The bracket is fixed to a pocket provided in the landing device and supports a landing door, and
The intra-tower cable is arranged such that a part of the intra-tower cable runs along the direction in which the bracket extends.

[Effect]

Since the present invention is constructed as described above, a bracket is fixed to the pocket supporting the landing door, and the in-tower cable is held by this bracket. As a result, the above-mentioned bracket is placed near the landing equipment, so the length of the tip of the in-tower cable that is routed along the hoistway wall from the bracket to the landing equipment can be shortened. Therefore, the number of holes for the metal fittings to be drilled in the hoistway wall as well as the metal fittings for holding the tip end are small.

〔Example〕

Hereinafter, the in-tower cable holding device of the present invention will be explained based on the drawings.

Figures 1 and 2 are explanatory diagrams showing one embodiment of the in-tower cable holding device of the present invention. Figure 1 is a perspective view of the main part seen from the hoistway to the landing door, and Figure 2 is the same as Figure 1. FIG. 3 is a plan view of corresponding main parts. In these FIGS. 1 and 2, parts equivalent to those shown in FIGS. 3 to 5 described above are designated by the same reference numerals.

1 and 2, a bracket 14 is fixed to the end of the pocket 4, and the intra-tower cable 7 is held by this bracket 14. The tip end 9 of this intra-tower cable 7
is, for example, wired along the wall of the hoistway 1 up to the push button device 5 and held by a metal fitting 10.

In the embodiment configured in this way, the bracket 14 that holds the intra-tower cable 7 can be placed near the hall equipment 6, so that the bracket 1
4 to the push button device 5, etc., there is no need for a long tip 9 of the tower cable 7, and therefore there are fewer metal fittings 10 for holding this tip 9, and there are many holes 11 in the wall of the hoistway 1. There is no need to drill holes.

[Effect of idea]

Since the in-tower cable holding device of the present invention is configured as described above, it is possible to route the tip of the in-tower cable to the landing equipment without drilling many holes in the hoistway wall. Therefore, compared to the conventional structure in which brackets for intra-tower cables are fixed to guide rails, it is possible to improve efficiency in arranging landing equipment.
