Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an elevator threshold fixing device.

[Prior art]

First, a conventional sill fixing device will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is a pedestal made of a support beam of an elevator landing, and 2 is a sill temporarily placed on the pedestal 1 via a wedge 3. That is, the threshold 2 needs to be placed at a predetermined position in each of the vertical, longitudinal, and width directions with respect to the pedestal 1, and horizontally.
For this reason, the position of the sill 2 is adjusted by the wedge 3, and the adjusted sill 2 is fixed to the pedestal 1 with mortar or the like.

However, the work of displacing the wedge 3 and temporarily placing the sill in a predetermined position requires skill and requires a long time. Furthermore, the sill 2 temporarily placed at a predetermined position may be displaced during mortar placement, making it difficult to fix the sill 2 at a predetermined position with high precision.

[Summary of the idea]

This invention solves the above-mentioned drawbacks and provides an elevator sill fixing device that has a position-adjustable structure and can easily fix the sill in a predetermined position.

[Example of idea]

3 to 11 show an embodiment of this invention. In the figure, the same reference numerals as in FIGS. 1 and 2 indicate the same or equivalent parts, 4 is the hall opening wall, 4a is the hoistway, 5 is a fixture for supporting the centering device on the wall 4, It has an L-shaped first claw 6 and a second claw 7,
As shown in FIGS. 6 and 7, the first claw fitting 6 consists of a claw member 6a of an appropriate length made of channel steel, and a channel steel member of an appropriate length joined at right angles to one end of the claw member 6a. It is composed of a support part 6b, and a screw hole 6c is provided at the non-joining end of the support part 6b.
is formed. As shown in FIGS. 8 and 9, the second claw metal fitting 7 includes a claw member 7a made of channel steel of an appropriate length, and a claw member 7a of an appropriate length joined at right angles to one end of the claw member 7a. The supporting portion 7b is made of a square cylindrical steel material. The first claw metal fitting 6 is slidably fitted into the support portion 7b, and as a result, as shown in FIG.
A guide hole 7c that coincides with the axis of the screw hole 6c is formed at the joint end of the claw member 7a with the support portion 7b. A tightening bolt 8 inserted into the support portion 7b from this guide hole 7c is screwed into the screw hole 6c. By rotating this tightening bolt 8, the fitting support portions 6b and 7b expand and contract to pinch the wall 4 interposed between the claw members 6a and 7a from both sides, and the fixture 5 is attached to the wall 4. It can be fixed. A reference metal fitting 5a and a support metal 5b are fixed to the support portion 7b of the second claw metal fitting 7 as shown in FIG. 9 is a sill mounting tool, two threaded rods 9a
is fixed in place. Whether it is the threshold for the central double sliding door or the threshold for the two-piece sliding door, it is fixed at any position of the threshold fixture 9 via the fastener 9d, depending on the respective width dimensions. A fixture 9b set on the threshold fixture 9 prevents the fastener 9c from rotating and lifting up. Further, 11 is a butterfly bolt for attaching the sill 2 to the sill fixture 9.

In this embodiment configured as described above, when centering and fixing the sill 2 to the cradle 1, the first,
The second claw fittings 6 and 7 are fitted with their supporting parts 6b and 7b, and the fastening bolt 8 is screwed into the screw hole 6c to form a U-shape, and the thus assembled fixture is assembled. 5 is temporarily set on the wall 4 so that the claw members 6a and 7a sandwich the wall 4 from the thickness direction. And reference line 13 (floor finishing architectural ink)
Align the lower end of the reference fitting 5a with the tightening bolt 8
The fixture 5 is fixed to the wall 4 by pinching the wall 4 from both sides by rotating it in the tightening direction.
The fixture 5 is also fixed to the opposite wall.

Next, the sill fixture 9 is attached to the threaded rod 9a through the elongated hole 5c provided upright on the support 5b, and the wing nut 10 is attached to the threaded rod 9a.
The mating plates 12 are screwed together as shown in FIGS. 3 and 4. Then, the sill 2 is fastened to the bottom surface of the sill fixture 9 via fasteners 9c and 9d. That is, both longitudinal ends of the sill fixture 9 are inserted into the U-shaped recesses of the fasteners 9c and 9d together with the sill 2, and the butterfly bolt 1 is inserted.
Tighten with 1. Next, the position of the sill 2 in the front, rear, left and right directions can be set by the play between the threaded rod 9a and the elongated hole 5c, and by rotating the wing nuts 10 and 10', the position of the sill 2 can be set in the vertical and The inclination of the threshold 2 is easily adjusted. Therefore, the sill 2 can be easily and accurately set at a predetermined position, and installation costs can be reduced.

[Effect of idea]

As mentioned above, this idea involves attaching a support with an elongated hole to the fixture that grips the hoistway wall, and suspending and fixing the sill via a screw inserted through this elongated hole. , in the depth direction by moving the support along the elongated hole, and
The position of the sill can be adjusted vertically using a screw mechanism. This adjustment operation can be easily performed and has the effect of providing high positional accuracy.
