Description

[Detailed Description of the Invention] The present invention relates to a mounting bracket for attaching a reflector that diffusely reflects light to a lighting device equipped with a light source such as a strobe or a lamp.

Lighting devices used for photography and movie shooting are equipped with reflectors that diffusely reflect the light from the light source in order to provide optimal lighting depending on the shooting environment and type of subject. There are many cases.

The important thing when installing such a reflector is to make sure that the reflective surface faces the light source as directly as possible to ensure that the light is reflected reliably and efficiently. A complicated and large mounting device was used to mount the reflector, making installation and adjustment very troublesome and difficult to work with, and also poor handling and portability due to bulk and weight issues. There was a drawback.

Therefore, in Japanese Utility Model Application Publication No. 52-18040, as a mounting device that can relatively easily attach a reflector to a lighting device, a support is provided on a mounting ring that is inserted into the strobe grip, and discloses a rotatably mounted umbrella fixing base having a hole for inserting an umbrella handle and a set screw for fixing the inserted handle.

However, the above mounting device has the disadvantage that the grip is easily damaged by the tightening of the fixing screw, because the clip of the strobe is inserted into the mounting ring and the tip of the fixing screw attached to the side of the mounting ring is pressed against the grip by tightening the fixing screw, and the fixed base is fixed at a specified angle by inserting the rotating shaft of the fixed base rotatably into the hole of the support base and tightening the rotating shaft with the adjustment screw on the side of the support base, so that even a slight loosening of the adjustment screw causes the fixed base to rotate due to the weight of the umbrella, and the umbrella is likely to bow, which is particularly noticeable when using large umbrellas. Moreover, since the angle of the umbrella must be set by rotating the fixed base after the umbrella is fixed to the fixed base, the operation is troublesome, and the work is complicated when using a large umbrella that is heavy.

An object of the present invention is to provide a reflector mounting bracket that allows a reflector to be easily and reliably attached to a lighting device without causing damage, and that allows for easy position adjustment of the reflector.

In order to solve the above problems, the mounting bracket of the present invention includes a band-shaped fixing member for fastening to a light source support rod in a lighting device, and a short rod-shaped reflector support integrally fixed to the fixing member. The band-shaped fixing member includes a worm for tightening and loosening operations at one end of a band piece wound in a ring shape, and a number of worms meshing with the worm at the other end. The support member for the reflector is provided with tooth holes, and is fixed to the side surface of the band-shaped fixing member in parallel with the ring formed by the fixing member, and has an axis therein that is inclined at a certain angle with respect to the center line of projection of light from the light source. It is characterized by having a rod insertion hole and a knob for fixing the shaft inserted through the insertion hole.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. As shown in FIGS. 1 and 2, a mounting bracket 1 is a band for fastening and fixing to a support rod for a light source in a lighting device. It consists of a fixed member 2 having a shape, and a support member 3 for a reflector in the shape of a short rod, which is integrally fixed to the fixed member 2.

The fixing member 2 has band pieces 2a and 2b wound in a ring shape, a worm 5 rotatably attached to the end of one band piece 2a via a holder 4, and a worm 5 attached to the other band piece 2b. It has many tooth holes 6 that mesh with the worm 5.
The band piece 2a can be tightened or loosened by pinching the operator 5a integrated with the fingertip or turning it with a tool such as a screwdriver, so that the band piece 2a can be attached to and detached from the light source support rod.

On the other hand, the support member 3 is fixed to the outer surface of the fixing member 2 with its axis oriented in a direction perpendicular to the central axis of the ring-shaped fixing member. so that along its length,
An insertion hole 7 inclined with respect to the axis of the support member 3 is formed in a plane parallel to the central axis of the fixed member 2, and a shaft 9 of a parasol-shaped reflector 8 (FIG. 4) is inserted into the insertion hole 7. A knob 10 is provided on the side surface of the support member 3 to fix the shaft 9 inserted into the insertion hole 7.

As is clear from FIG. 4, the reflector 8 has a shape almost similar to that of an ordinary Western umbrella, and the inner surface of the screen 11 corresponding to the umbrella cloth is used as a diffused reflection surface.
1a.

As shown in FIGS. 2 and 4, the mounting bracket 1 having the above configuration is constructed by fitting the fixing member 2 onto the support rod 14 of the light source 13 in the lighting device 12 and tightening the fixing member 2 with a worm 5. Fix it by.

Then, the shaft 9 of the reflector 8 is inserted into the insertion hole 7 of the support member 3, and the shaft 9 is fixed with the knob 10.

This completes the attachment of the reflector 8 to the illumination device 12. At this time, by moving the shaft 9 in the length direction and adjusting the fixing position with respect to the support member 3, the reflection surface 1 of the reflector 8 can be adjusted.
The center O of 1a can be aligned on the projection center l of the light from the light source 13.

In addition, if it is necessary to adjust the direction of the reflector 8 around the axis of the support rod 14, use the worm 5.
Adjustments can be made by loosening the fixing member 2.

As described above, according to the mounting bracket of the present invention, the band-shaped fixing member is wound in a ring shape and fitted onto the support rod of the light source, and the fixing member is tightened with a worm to be fixed to the support rod. Therefore, as in the conventional example disclosed in Japanese Utility Model Application No. 52-18040, the ring was fitted into the support rod, and the fixing screw provided on the ring was tightened to lock the tip to the side of the support rod. Compared to the fixing method, it is possible to securely fix the fixing member without damaging the support rod, and since the lights and legs are attached to the upper and lower ends of the support rod, the above-mentioned ring can be attached from the end. Even if it is not possible to fit the
The mounting bracket of the present invention can be installed reliably by simply opening the band-shaped fixing member, wrapping it around the support rod from the side, and then tightening it with a worm.

Moreover, in the above conventional example, in order to be able to handle support rods with different diameters, it is necessary to increase the length of the fixing screw to match the small diameter support rod. The disadvantage is that when attached to a rod, the head of the fixing screw protrudes greatly from the side of the ring and gets in the way.
The mounting bracket of this invention uses a band-shaped fixing member wrapped around it and tightened with a worm, so it can be installed snugly along the outer circumference of the support rod without getting in the way, regardless of the diameter of the support rod. I can do it.

In addition, an inclined shaft insertion hole is drilled inside the reflector support member, and the support member is fixed to the side surface of the band-shaped fixing member in parallel with the ring, so that the reflector can be inserted into the inclined insertion hole. By simply inserting and fixing the shaft rod, the reflector can be easily and securely mounted on the center line of the projection of light from the light source, and the position of the reflector can be adjusted by simply sliding the shaft back and forth. Since there is no need to rotate the support member, adjustment work is very simple, and even when using a large and heavy reflector, the weight of the reflector will rotate the support member and cause the reflector to bow. This does not cause any inconvenience at all. Moreover,
Although the shaft insertion hole is inclined with respect to the fixed member, the supporting member is not inclined, so regardless of the length of the supporting member, both ends will not protrude up or down from the fixed member. Therefore, it is easy to store and store the mounting bracket, and it can be placed stably in the storage location.
