Abstract

PURPOSE:To provide an elevator for elevating an illumination lamp or the like capable of preventing the elevator from tilting by providing an elastic positional change stopping means for stopping the changes of postural relation between a wire guide and the elevator by means of an elastic force. CONSTITUTION:A tubular wire guide 4 for guiding that portion of a wire 1 which extends from an elevator 2 or that portion which leads to the elevator 2 is pivotally mounted on the elevator 2 by a turning movement shaft 5 in such a manner as capable of freely oscillating, and an elastic positional change stopping means 6 is provided for stopping the positional changes of the wire guide 4 and the elevator 2 relative to each other by means of an elastic force. Thus, when the wire 1 is wound or rewound, even if the wire guide 4 guiding the wire 1 tends to change its position relative to the elevator 2, the relative positional change is stopped by the elastic force of the plate spring 18 of the elastic positional change stopping means 6 whereby the elevator 2 is restrained from tilting.

Description

DETAILED DESCRIPTION OF THE INVENTION 1. Field of Industrial Application The present invention relates to a lowering device for lowering, for example, a lighting fixture, etc. This relates to a technique that attempts to suppress the inclination of an elevating body when elevating the body.

[Prior art 1] A wire 1, which was conventionally suspended from a ceiling, etc., is wound around a plurality of wheels 3 provided approximately horizontally on an elevating body 2, and is led out from the elevating body 2. The elevating body 2 is raised and lowered by winding and unwinding the wire 1.

[Problems to be solved by the invention] When lowering and lowering the lowering body 2 using the single-winding method as described in -1-1, it is necessary to lower the wire feeding side when lowering. There was a problem in that the elevating body tilted, and when it was lifted up, the elevating body tilted so that the winding side of the wire was raised. In order to solve this problem, as shown in Fig. 5, a guide hole is formed on the main body 7 side, a guide 8 is made to protrude on the elevating body 2 side, and this guide 8 is fitted into the guide hole. However, if the guide 8 comes out of the guide hole, the elevating body 2 will still be tilted. If the elevating body 2 is tilted in this way, the guide 8 will fit into the guide hole and cannot be removed. Therefore, as shown in Figure 6, the guide 8 is formed into a cylindrical shape and the wire 1 is inserted through the guide 8. At the same time, the guide 8 is rotatably pivoted around the rotation shaft 5, and the relative rotation between the guide 8 and the '71 lowering body 2 is achieved within the range of engagement between the elongated hole 9 and the bin 10 of the lifting body 2+llll+. Set the motion to RQ' %F, and then wire 1
It is also conceivable that the guide 8 be aligned with the guide hole so that the guide 8 can be easily inserted into the guide hole.

However, in this way, the guide 8 is aligned with the elevating body 2.
j Despite having a configuration that allows rotation, the elevating body 2 is more prone to inclination, and the inclination of the elevating body 2 increases, creating a need for jerky to correct the inclination, creating a sense of anxiety and reducing the product value. There were other problems.

The present invention was made in view of such problems,
The purpose is to provide an elevating device that can suppress the inclination of an elevating body through simple improvements.

Means for Solving 1 Problem] The lifting device of the present invention has a single wire 1 suspended from a ceiling or the like and wound around a plurality of wheels 3 provided on a lifting body 2 in a substantially horizontal direction. wire 1 led out from the lifting body 2
It is a lifting device that raises and lowers the lifting body 2 by winding and unwinding the lifting body 2, and is a knot-shaped wire guide 4 that guides the wire 1 portion led out from the lifting body 2 or the wire 1 portion leading to the lifting body 2. is pivotally connected to the elevating body 2 by a rotation shaft 5 so as to be able to swing freely in the left and right direction, and the wire guide 4 and the gear 1 are
This device is characterized by being provided with elastic posture change prevention means 6 that prevents changes in the relative posture with respect to the lowering body 2 with elastic force.

[Operation 1] In this way, the cylindrical wire guide 4 that guides the 1 part of the wire led out from the elevating body 2 or the 1 part of the wire leading to the elevating body 2 is swung in the left-right direction on the rotating shaft 5 on the elevating body 2. By providing an elastic posture change prevention means 6 which is movably pivoted and prevents a change in the relative posture between the wire guide 4 and the elevating body 2 with elastic force, the wire 1 is Even if the wire guide 4 along which the wire 1 is idly moves towards the elevating body 2 and its relative attitude is to be changed, the change of this phase jJ attitude can be elastically changed. to prevent it with
The tilting of the elevating body 2 is suppressed.

[Example] Embodiments of the present invention will be described in detail below based on the drawings.

Figures 1 and 3 show the overall configuration, and the ceiling 10
A wire 1 is suspended from the ceiling 10 within a casing 11 attached to the casing 11, and this wire 1 is connected to two V-pulley-like roller wheels 3 provided approximately horizontally on the elevating body 2. Wire 1 wound and led out from the elevating body 2
is introduced into the casing 11, wound around the guide roller 12, and wound around the drum 13 which is rotated for winding and rotation by a motor (not shown), and is then rotated under the controlled rotation of the Y ram 13. By winding and unwinding the wire 1, the elevating body 2 can be moved up and down. Even if this elevating body 2 is equipped with a lighting illusion or something else, no.

In such a case, a cylindrical wire guide 4 for guiding the 1 part of the wire led out from the elevating body 2 and the 1 part of the wire leading to the elevating body 2 is made to protrude from the elevating body 2. Wire 1 is inserted. A guide hole 14 is formed in the casing 11, and the wire guide 4 can be smoothly introduced into the guide hole 14 by a guide portion 15 having a substantially trumpet shape.

And such a wire guide 4 has J at its base 16.
