Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture mounting mechanism, and relates to a lighting fixture suitable for use, for example, in lighting for photographing a video camera.

A conventional mounting mechanism for this type of lighting equipment, for example, a lighting equipment used as lighting for photographing a video camera, is that a mounting leg is provided on the main body of the lighting equipment, and a C-mounted lamp attached to the video camera is attached to the mounting leg. A mounting mechanism is constructed by attaching a mounting body having a fitting part to a letter-shaped mounting seat and a threaded part of a hand screw that presses the mounting seat by screwing a hand screw into the threaded part of the mounting body. Then, the fitting part of the mounting body is fitted into the mounting seat attached to the video camera, and the mounting seat is pressed by tightening the hand screw, the mounting body is attached to the mounting seat, and the main body of the device is attached to the video camera. It is configured to be attached to a camera.

In the lighting fixture mounting mechanism configured as described above, the mounting body is attached to the mounting leg of the fixture body with a hand screw, so if the hand screw is loosened too much, the threaded joint between the hand screw and the mounting body When the screw is released, the hand screw will be removed from the mounting leg and the mounting body will also be disengaged from the mounting leg, resulting in the loss of the hand screw and the mounting body and the need to reinstall the hand screw and the mounting body. This has the disadvantage that it is troublesome to use, and that when the hand screw is tightened and the mounting seat is pressed, the mounting seat is damaged by the hand screw.

The present invention relates to a lighting fixture mounting mechanism that eliminates the above-mentioned drawbacks.

An embodiment of the lighting fixture mounting mechanism of the present invention will be described below with reference to the drawings.

The mounting mechanism of the lighting equipment of the present invention is such that the mounting leg 2 of the main body 1 of the luminaire is divided into two parts, and the insertion hole 4 of the hand screw 3 is provided straddling the joint part of the upper surface of the two parts of the mounting leg 2. A sliding hole 6 for slidably attaching the clamping body 5 is provided at the joint part on the lower surface of the mounting leg 2, and a threading part 7 of the hand screw 3 is provided on one side of the clamping body 5.
and a screw hole 8 into which a tightening screw 17 of a tripod 16, which will be described later, is screwed into the other side, and a mounting portion 9 which slidably attaches the clamping body 5 to the mounting leg 2.
and a clamping part 1 that comes into contact with one of the clamping pieces 11 of an object to be mounted 10 such as a mounting seat attached to a video camera or the like.
2, and the clamping body 5 is mounted on the mounting leg 2 between the mounting part 9 and the clamping part 12 of the clamping body 5.
The hand screw 3 is slidably attached to the mounting leg 2 by the mounting portion 9 of the clamping body 5 and the clamping portion 12, and the shaft portion 13 of the hand screw 3 is attached to the mounting leg 2. is positioned in the insertion hole 4 of the mounting leg 2, the threaded portion 7 of the hand screw 3 is positioned within the mounting leg 2, and movably attached, and the clamping portion 12 of the clamping body 5 is mounted.
is inserted into the object to be attached 10 and abuts on one side of the clamping piece 11, and the hand screw 3 is inserted into the screw hole 8 of the clamping body 5.
and tighten the hand screw 3 by screwing together the threaded part 7 of the
The clamping body 5 is slid on the mounting leg 2 so that the clamping part 12 of the clamping body 5 and the clamping surface (bottom surface) of the mounting leg 2 are separated.
15, and the above-mentioned instrument main body 1 is attached to the object 10 to be attached.
It is configured to be attached to.

In the above configuration, the hand screw 3 is formed in the mounting leg 2 so that the threaded portion 7 of the hand screw 3 has a diameter larger than the diameter of the insertion hole 4 of the mounting leg 2. For example, it is formed so that it can be divided into two parts, and the threaded part 7 of the hand screw 3 and the attachment part 9 of the clamp body 5 are attached so as to be movable and slidable, respectively, and the light fixture can also be attached to a tripod. In particular, as shown in FIG. 3, when the clamping body 5 is tightened with the hand screw 3 and the clamping body 5 is fixed to the mounting leg 2, the tightening of the tripod 16 can be done from the other side of the threaded hole 8 of the clamping body 5. Attached screw 17
The threaded portion 7 of the hand screw 3 is formed short so that it can be screwed together and tightened.

Since the lighting equipment of the present invention has the above-mentioned configuration, even if the hand screw is loosened too much and the threaded connection between the hand screw and the clamping body is released, the hand screw and the clamping body will be removed from the mounting leg. It will not come off and therefore the hand screw and the clamp can be prevented from being lost.

In addition, even if the object cannot be held by the clamping body, if the body has a tightening screw, the tightening screw can be screwed into the threading hole of the clamping body. A lighting fixture can be attached to an object.
