Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a slot head in a photography strobe, and more particularly to a mounting structure for a glass globe that covers a xenon tube that is a light emitter.

[Prior Art] Generally, this type of slot head has a structure as shown in FIG. In the figure, numeral 30 is a head main body, in which a trigger coil, fan, etc. are housed, and the top surface is a socket 30a. 32 is a xenon tube that is a light emitter.
In this figure, the xenon tube 32 is attached to a base 31 and the legs 31a of the base 31 are inserted into the socket 30a for electrical connection, but since the socket 30a and the base 31 are not present, the There is also a structure that is attached to 30. Reference numeral 34 denotes a glass globe, which is provided with a ventilation hole 38 on its outer periphery, and a metal ring 36 is fitted to the outer periphery of its lower end. 36a.
The glass globe 34 is detachably attached to the base 31 by hooking a hook spring 37 around the outer periphery of the metal ring 36. The lower end of the hook spring 37 is attached to the base 31 by means of screws or the like. 39
is the reflector 3 in the casing of the head body 30.
5 is attached to the opening.

Fig. 4 shows a structure in which a metal ring 36 is attached to the lower end of the glass globe 34.
As shown in the figure, there is a structure in which a flange is integrally molded at the lower end of the glass globe 40 and fixed with a hook spring 37, and a structure in which a hook spring 42 is hooked and fixed in a ventilation hole 41a as shown in FIG. 6 is available.
However, since the number of glass globes 40, 41 manufactured is small, the tube-shaped glass is heated to round the tip and then cut, instead of being molded.
Since each piece is manufactured individually by hand by drilling a hole in it, the dimensions of each part cannot be made constant. Therefore, the fifth
An integrally molded glass globe as shown in FIGS.

[Problems to be solved by the invention] However, since compatibility with other models is usually required for this type of slotted head, the diameter of the attachment part of the reflector 35 to the head body 30 is specified. For example, when using a large xenon tube 32 with high output, the diameter of the glass globe is inevitably increased, so the space between the glass globe and the reflector 35 becomes narrower.

However, since the outer diameter, flange dimensions, and ventilation hole positions of the integrated glass globes shown in Figures 5 and 6 are not constant, problems occur in how the hook springs hold the glass globes, resulting in failures. It was complete and easy to remove.

Therefore, we had no choice but to adopt a glass globe with a metal ring of fixed dimensions fixed to the lower end as shown in Figure 4, but this metal ring was used both to fit the glass globe and to hold the hook spring. In order to provide a flange for hanging, the diameter is larger than the outer diameter of the glass globe, resulting in an even narrower gap between the reflector and the inner diameter.

The present invention was developed in view of the above-mentioned circumstances, and an object thereof is to provide a slotted head that can securely attach a glass globe with a simple configuration even when the space between the reflector and the glass globe is narrow. It is.

[Means for Solving the Problems] The slotbo head of the present invention includes a head body equipped with a light emitter, a glass globe mounted on the light emitter, and a reflector attached to the head body. At least one engaging part formed by a recess, a hole, etc. is provided on the top of the clamper, an elastic wire is formed into a substantially U-shape, and a protrusion that fits into the engaging part is provided. It is characterized in that the lower end is removably attached to a predetermined position on the base of the light emitting body, the head body, the reflector, etc. by resiliently engaging the engaging portion.

[Function] Even if the gap space between the glass globe and the reflector is narrow, the glass globe can be reliably attached due to the elasticity of the clamper.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

In Fig. 1, 1 is the head body, and the outer body 1
A light emitting unit 2 having a xenon tube 4 attached to a base 3 is removably mounted in a socket type. Reference numeral 5 denotes a reflector that is attached to the casing 1a of the main body 1, and since compatibility is required, the diameter of the attachment part is specified. 6 is a glass globe that covers the xenon tube 4, and is fixed on the base 3 by a clamper 7, which will be described below.

The clamper 7 is formed from an elastic wire such as a stainless steel wire in a substantially U-shape, and has an engaging portion 6a formed in the center of the top surface of the globe 6 as a recess. A convex portion 7a is provided to protrude inwardly so as to elastically engage with and press the entire glove 6 against the base 3. The lower ends of the clampers 7 are each bent inward and fixed to the lower surface of the base 3 with screws 8 or the like. Therefore, the glove 6 is reliably fixed on the base 3 by the elasticity received from the convex portion 7a of the clamper 7. In addition, when putting on and taking off the glove 6, use the clamper 7.
It can be attached and detached extremely easily by simply bending the upper part of the cover to the side against its elasticity.

The lower end of the clamper 7 may be fixed to the casing 1a of the head body 1 as shown in FIG. 2, or to the reflector 5, the socket 1b of the head body 1, etc. . Furthermore, the lower end of the clamper 7 may be fixed to any of the above locations with screws, screws, etc., or may be secured to a protrusion, hole, etc. In the case of FIGS. 1 and 2, although the engaging portion 6a is not shown, the hole passing through the inside is also included in the range. FIG. 3 shows another embodiment of the clamper, in which a glass globe 16 is mounted on the base 3 by two clampers 17, 17. In this case, an engaging part 16a, which is a recess with a larger diameter than that shown in FIG. The glove 16 is fixed onto the base 3 by elastically engaging the end edge of the engaging portion 16a. Note that the large diameter engaging portion 16a
Instead, two depressions or holes are provided, and the hook-shaped protrusions 17a, 1 of the clampers 17, 17 are provided respectively.
7a may be locked.

[Effects of the Invention] As explained above, according to the present invention, even if the gap space between the glass globe and the reflector is narrow, the glass globe can be reliably attached using a clamper having a simple configuration.

In addition, even if the glass globe has inaccurate dimensions, it is possible to reliably cover the luminous object, and
If the glass globe is not needed, you can also remove it.
