Description

[Detailed Description of the Invention] The present invention relates to an improvement of a sliding guide shoe for an elevator.

The sliding guide shoe of this type of elevator guides the car and the counterweight by sliding a slider on a guide rail disposed in the hoistway.

Figures 1 and 2 show a sliding guide shoe of a conventional elevator.This will be briefly explained based on the figure.In the figure, the reference numeral 1 is a guide rail, and a plurality of guide rails are arranged in the vertical direction. It is connected to and arranged in the hoistway. Reference numeral 2 denotes a slider attached to the sliding guide shoe body 5 by upper and lower presser feet 3 and 4, and is configured to slide on the guide rail 1 in contact with the contact surfaces 1a, 1b and 1c. There is. The slider 2 is entirely made of a soft material, thereby reducing impact noise and vibrations generated when the slider 2 passes through a stepped portion at the joint of the guide rail 1.

However, since the slider 2 made of a soft material has a small permissible load, there is a drawback that the slider 2 will wear abnormally if a heavy load is applied due to unbalanced loading or the like.

Therefore, in the conventional slider 2, as shown in FIG. 3, the central running part 2a is made of a hard material, and the central running part 2a is made of a soft material and is curved and thin so as to be spaced apart from the guide rail 1 toward the tip. There is also one that consists of both upper and lower end portions 2b.

However, in this case, the central running portion 2 of the slider 2
There is a problem in that impact noise and vibrations cannot be significantly alleviated due to impact noise and vibration caused by collision of the bumper a with the corner of the stepped portion.

The present invention was developed in view of these circumstances, and includes a slider having a surface facing the guide rail, and a contact surface that is elastically held on the sliding surface side of the slider so as to be able to move forward and backward, and is in pressure contact with the guide rail. To provide a sliding guide shoe for an elevator that can prevent wear of the slider and reduce impact noise and vibration by having an extremely simple structure including a movable slider.
Hereinafter, the configuration and the like will be explained in detail by referring to embodiments shown in the drawings.

4 to 7 show a slider in the sliding guide shoe of an elevator according to the present invention, and in the following figures, the same members as in FIGS. 1 to 3 are given the same reference numerals and detailed explanations will be given. is omitted. In the figure, the reference numeral 11 denotes a slider attached to the sliding guide shoe body 5, which has curved surfaces 12 at both ends and a surface 13 facing the guide rail 1, and is entirely made of a hard material. There is. This slider 11 is provided with a recess 14 that opens toward the guide rail 1 side. Reference numeral 15 denotes a movable slider made of a soft material, which has curved surfaces 16 at both ends and is attached to the sliding surface side of the slider 11 via an elastic member such as rubber 17 or a spring 18 installed in the recess 14. It is elastically held so that it can move forward and backward, and a contact surface 1 that presses against the guide rail 1 is provided at the end on the guide rail 1 side.
9 is formed. The movable slider 15 is retracted so that the contact surface 19 is positioned at the same level as the surface 13 of the slider 11.

Therefore, as shown in FIG.
When a light load is applied to the slider 1, the sliding guide shoe slides on the guide rail 1 by contacting only the contact surface 19 of the movable slider 15. Further, as shown in FIG. 9, when a heavy load F is applied to the slider 11, the contact surface 19 of the movable slider 15 and the surface 13 of the slider 11 come into contact and slide.
In this case, the movable slider 15 is retracted into the recess 14 by the reaction force obtained by pressing against the guide rail 1, so that the contact surface 19 and the surface 13 are positioned at the same level.

In this embodiment, the movable slider 15 is elastically held by the slider 11 via an elastic member such as rubber 17, but the present invention is not limited to this. As shown in FIG. 11, the movable slider 15 may be simply formed integrally with the slider 11 to be elastically retained.

As explained above, the present invention includes a slider and a movable slider elastically held on the sliding surface side of the slider so that it can move forward and backward, and when the movable slider retreats, the movable slider Since the contact surface of the slider is positioned at the same level as the surface of the slider, it is possible to reliably reduce impact noise and vibrations generated when the slider passes over the guide rail and the stepped portion of the guide rail joint. In addition, when a heavy load is applied to the slider, the contact surface of the movable slider and the surface of the slider can slide on the guide rail, sharing the load and preventing abnormal wear on the slider. . Furthermore, if the slider and the movable slider are made of hard and soft materials, respectively, the movable slider will follow the stepped portion when the sliding guide shoe passes through the joint of the guide rail.
Impact noise, vibration and wear can be significantly reduced.
