JPH0733372A - Sliding device for skew elevator - Google Patents

Abstract

(57) [Summary] [Structure] In the hoistway 1 between the car door sill 9 and the landing door sill 13 and the car-side guide rail 3, the toe guards 10 and 12 attached to the sill are used as partitions. The toe guard is as long as or longer than the sill, and serves as a tray for foreign matter that falls from both side edges of the sill or the dust drop holes. [Effect] Even if foreign matter that occurs when passengers get on the elevator falls into the hoistway from the hole in the threshold, the foreign matter is received by the toe guard, so that the foreign matter does not directly adhere to the guide rail.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sill apparatus for an oblique elevator, and more particularly to a dustproof structure for an oblique elevator guide rail.

[0002]

2. Description of the Related Art As a conventional known example, as described in Japanese Utility Model Laid-Open No. 4-84277, a dustproof structure of a diagonal elevator guide rail is continuously provided along the longitudinal direction of a hoistway regardless of whether there is an entrance or exit. It was a sill device with a dust pan.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned prior art, the length of the hoistway is the same as that of the elevator stroke, or
Since the dust pan with a length longer than that is continuously installed, the number of parts in the dust pan increases in an elevator with a long up-and-down stroke.
The production cost was high, and the on-site installation work was not easy.

An object of the present invention is to prevent dust, pebbles, water droplets, etc., falling from the dust drop hole of the sill from adhering to the guide rails of the car when the elevator is getting on and off, thereby improving the riding comfort and safety of the elevator. Especially.

[0005]

In order to achieve the above object, the present invention relates to a rail provided along a longitudinal direction of an inclined elevator hoistway and an oblique elevator provided with an entrance / exit to the hoistway. A toe guard having the same length as or longer than the sill was provided from the tip of the elevator door sill and the car sill. The toe guard fixed to the tip of the sill has an L-shaped shape that is bent under the sill to the landing side and the car side, respectively, so that dust and small stones falling into the hoistway from the sill drop hole can be received. .

[0006]

[Operation] Dust, pebbles, and water droplets that fall from the dust drop hole of the sill when getting on and off the elevator will serve as a dust pan because the toe guard fixed at the tip of the sill extends vertically below the sill. It does not directly adhere to the guide rails of the car installed below. Therefore, the upper surface of the guide rail is always smooth, and the car moving up and down on this surface travels smoothly.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2 and 3. FIG. 1 is a front sectional view of a hoistway of an oblique elevator. FIG. 2 is a partial detailed view of a sill apparatus for an oblique elevator according to the present invention. FIG. 3 is a front view of the hall door sills.

A guide rail supporting device 2 is erected on the concrete wall covering the oblique path 1, and a weight guide rail 17 is balanced by a car guide rail 3 and is fixed by rail clips 5 and bolts 6, respectively. Cage,
The car frame 7 moves up and down on the upper surface of the car-side guide rail. A car floor 8 is installed on the car frame 7, and a car door sill 9 is attached to a part of the floor. A concave groove is continuously provided in the car door sill 9 in the longitudinal direction, and the car door 11 slides in the concave groove. A dust drop hole 19 is formed in a part of the concave groove of the car door sill so that a foreign object 18 brought in by a passenger or the like does not collect. Further, the counterweight 21 to which the guide roller 4 is fixed can move up and down on the upper surface of the counterweight side.

On the other hand, the hoistway wall 15 on the hoistway side of the hoistway is installed on the hall door sill 13 via a mounting bracket 20. The landing door sill is provided with a concave groove so that the landing door 14 engages and moves. Like the car door sill, a dust drop hole 19 is formed in a part of the concave groove. A car door toe guard 12 and a landing door toe guard 10 are attached to the sides of the car door hall door sill by screws 22. The toe guard has a length equal to or longer than the car doors and landing door sills installed along the doorway, and is extended from the vertical direction to the landing side and the car side, respectively, and the lower part of the sill is placed. It has been covered.

[0010]

EFFECTS OF THE INVENTION According to the present invention, even if a foreigner or a liquid that has entered a concave groove of a sill when a passenger or the like gets into an elevator, it is installed below the sill even if it falls into the hoistway from the concave groove of the sill or the dust drop hole. Since the guide rail falls to the toe guard provided directly below the sill before adhering to the moving surface of the car frame of the guide rail, the guide rail is not contaminated and a safe and comfortable elevator can be supplied.

Further, since the toe guard is also used as the dust receiving box,
Since it does not require the same length as the elevator stroke along the longitudinal direction of the elevator as in the past, the number of parts is small and the parts can be produced at a low cost, and the on-site installation work and man-hours can be reduced.
