[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stage suspension supporting device used for suspending a curtain or a suspended object from above a stage in a theater or the like.

[0002]

2. Description of the Related Art In a theater or the like, various curtains, luminaires, and other various tools necessary for performance are suspended from above a stage by using chains, wires, hooks, and the like. These tools are usually used by suspending them from support rails that are permanently installed at intervals such as the ceiling of a theater stage. Then, these tools are exchanged or moved to another support rail according to the performance of the stage and the progress of the scene. For these operations, large-scale ones and permanent ones are usually operated electrically, but those specially made according to the items on the stage are quickly operated by the tool clerk working behind the scenes. There is. Since the hanging position of the hanging object on such a stage is determined by the position of the support rail provided above the stage, when it is desired to shift the hanging position of the hanging object on the stage, a chain, a wire, or a hook is used. The height is adjusted by displacing it.

[0003]

By the way, in order to support the hanging object on the stage as described above, it is necessary to firmly support the hanging object so that the hanging object does not fall or come off. Depending on the situation, it is necessary to remove it, replace it, or add another hanging object at a slight time such as in the interlude, so the operability must be good. However, with the chains, wires, hooks, etc. that have been used conventionally, it takes time for the tool clerk to stop and remove, especially when the suspended object is relatively heavy, and prompt operation is required, and the working environment is The fact is that it is dark and not stable, so there is no room to check whether it has been stopped securely. As a result, there is a problem in that the chain, the wire, and the hook cannot be reliably stopped, and it takes a lot of time to remove them, resulting in very poor operability.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a suspension support device for a stage which can be removed and fixed quickly and reliably.

[0005]

In order to achieve the above object, an upper portion is formed to have a substantially constant width, and an upper end portion thereof is fixed to a suspension support portion such as a ceiling of a stage. It has a plate-shaped main body having a first receiving portion formed by bending a portion to receive a supporting member for supporting an object to be suspended, and a tip of the first receiving portion and a tip of the second receiving portion in a lower portion of the plate-shaped main body. The shapes of the first and second receiving portions are set to a shape suitable for receiving the support member in a state where they are in contact with each other,
A plate-shaped cooperating member, which is rotatably fixed to the upper portion of the plate-shaped main body by extending the upper end of the second receiving portion to have a width substantially the same as the width of the upper portion of the plate-shaped main body, When the first receiving portion and the second receiving portion of the plate-shaped cooperating member rotate in a substantially same plane and their tips abut against each other, the upper portion of the plate-shaped main body and the plate-shaped co-operating member move together. And a slidable annular latching member for latching the first and second receiving portions in a closed state by fitting with the extending portion of the upper end of the moving member and fitting the overlapping members. It is characterized in that both the first and second receiving portions can be opened by sliding the annular retaining member along the upper portion of the plate-shaped body toward the upper end.

[0006]

In the hanging support device for a stage according to the present invention having the above-mentioned structure, the annular hooking member is slid up and down along the upper portion of the plate-like main body so that the first and second
The receiving part can be opened or kept closed. Moreover, this ring-shaped latching member is assembled so that it cannot be removed from the main body, and it is held in the latching position by the action of gravity during normal use, so that it does not depend on the weight of the suspended object. There is no risk of the part opening, and a reliable locking action is obtained. Further, when removing the latch, both annular receiving portions can be easily opened by shifting the annular latch member upward.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an embodiment of the present invention. In the illustrated apparatus, reference numeral 1 is an iron plate-shaped main body, an upper portion 2 thereof extends linearly with a constant width, and a tip thereof is formed wide. A hole 3 for mounting the chain is provided as shown in FIG. The lower portion 4 of the plate-shaped body 1 is formed to have a width narrower than that of the upper portion 2, and is bent in a U-shape to form a first receiving portion 5. The tip 6 of the lower portion 4 is bent at a right angle to the plane of the plate-shaped body 1. Further, 7 is a plate-shaped cooperating member made of iron, and an upper portion 8 thereof is formed to have substantially the same width as the upper portion 2 of the plate-shaped main body 1 and a length of about half. Further, the lower portion 9 of the plate-shaped cooperating member 7 has substantially the same width as the lower portion 4 of the plate-shaped main body 1 and is bent in a U-shape to form a second receiving portion 10. The tip 11 of the lower portion 9 is bent at a right angle like the plate-shaped body 1. The upper portion 8 of the plate-shaped cooperating member 7 is superposed on the upper portion 2 of the plate-shaped main body 1, and the tip end thereof is rotatable with respect to the intermediate position of the upper portion 2 of the plate-shaped main body 1 by a fixing member 12. It is fixed to. An iron hooking member 13 made of iron is vertically slidably mounted on the overlapping upper portions 2 and 8, and the ring hooking member 13 is shown in FIGS. 1 (A) and 2 (C). When the plate-shaped cooperating member 7 is moved upward along the upper part 2 of the plate-shaped main body 1, the plate-shaped co-operating member 7 is detached from the tip of the upper part 8 and the plate-shaped co-operating member 7 can be rotated laterally. Is set to When the ring-shaped latch member 13 is lowered downward as shown in FIGS. 1B and 2A, the plate-shaped main body 1
