Description

[Detailed explanation of the idea] <Industrial application field> The present invention relates to a hand lamp.

<Prior Art> Conventional hand lamps have only a normal lighting function. In addition, in hand lamps that can be used as red emergency lights at appropriate times, a filter for emitting red light is integrated with the hand lamp, or it is attached to the front of the hand lamp even though it has a complicated structure. . Therefore, the former type can be easily converted to red light, but it is not possible to emit color light other than red light, or convert it to diffused light or spot light, and the latter type requires filters and lenses. Not only is it troublesome to replace, but when the filter and lens are not in use, they must be stored separately from the hand lamp, resulting in the problem of powder being lost or broken.

<Problems to be solved by the invention> The present invention was made in view of these conventional problems, and includes a filter for emitting red and yellow colored light and a lens for emitting diffused light and spot light. To provide a hand lamp in which a filter (hereinafter referred to collectively as a filter) can be easily attached and removed from the front of the hand lamp body, and an unused filter can be easily and securely stored in the back of the hand lamp body. It is.

<Means for solving the problem> The hand lamp of the present invention that achieves the above object has an annular recess for attaching a filter on the front periphery of the hand lamp body, and an annular recess for storing the filter on the back periphery of the hand lamp body. It is characterized by having a plurality of elastic locking pieces protruding from the outer periphery of the filter, and detachably attaching the filter to the annular recess for attaching the filter and the annular recess for storing the filter.

<Example> Hereinafter, an example of implementing the present invention will be described based on the drawings.

The hand lamp body 1 is made of a material such as plastic and is formed into a box shape with a front surface approximately circular or a front surface approximately arch-shaped, and a lamp unit 2 is incorporated therein so as to face forward inside the box, and the front peripheral edge 1a
An annular recess 3 for attaching a filter is formed at the rear periphery 1b, an annular recess 4 for storing the filter is formed at the rear peripheral edge 1b, and a handle 6 is provided at the rear of the hand lamp body 1.
The filter 5 is attached to the annular recess 3 for attaching the filter so as to be able to rise and fall freely, and the filter 5 is detachably attached so as to cover the front surface of the lamp unit 2.
An unused filter 5 is detachably stored in an annular filter storage recess 4.

The annular recess 3 for filter attachment is formed in a front circular shape on the front peripheral edge 1a of the hand lamp body 1 so as to surround the outer periphery of the lamp unit 2, which is circular in front.The annular recess 4 for filter storage is an annular recess for attaching a filter. 3 and is formed in a circular shape on the back peripheral edge 1b of the hand lamp body 1.

The filter 5 is a colored filter for emitting colored light such as red or yellow, or a lens formed with a lens step for emitting diffused light or spot light. The annular recess 3 and the annular filter storage annular recess 4 are formed into a shallow dish shape with a diameter slightly smaller than the inner diameter thereof, and a plurality of elastic locks are formed on the outer periphery of the annular recess 3 and the annular recess 4 for filter storage to make elastic contact with the inner surfaces of the annular recess 3 and the annular recess 4 for filter storage. A piece 9 is formed to protrude, and a window hole 8 is formed in the center of the hand lamp body for allowing a lamp switch 7 to protrude when the filter 5 is installed in the annular recess 4 for filter storage of the hand lamp body 1. The elastic locking pieces 9 are for attaching and supporting the filter 5 to the filter mounting annular recess 3 or the filter storage annular recess 4 of the hand lamp body 1, and a plurality of elastic locking pieces 9 are arranged around the outer circumference of the filter 5 at appropriate intervals. It is formed into a tongue shape that elastically projects and comes into elastic contact with the inner surfaces of both the annular recesses 3 and 4 of the hand lamp body 1, and its tip 9a contacts the bottom surface 3 of both the annular recesses 3 and 4.
It is formed to protrude so as to come into contact with a and 4a.
Therefore, when the filter 5 is attached to the filter mounting annular recess 3 of the hand lamp body 1, the elastic locking piece 9 is elastically abutted and locked on the inner surface of the annular recess 3, and the elastic locking piece 9 is The tip 9a comes into contact with the bottom surface 3a of the annular recess 3 and is slightly separated from the surface of the lamp unit 2. In this way, by mounting the filter 5 a little apart from the surface of the lamp unit 2, the filter 5 can be protected from the heat generated by the lamp unit 2.

In addition, as in the illustrated embodiment, the hand lamp body 1
By forming a finger hook recess 10 in a notch shape in a part of the annular recess 3 for filter attachment and the annular recess 4 for storing the filter, it is possible to remove the filter 5 from both the annular recesses 3 and 4 of the hand lamp body 1. , the filter 5 can be easily removed by inserting a finger into the finger hook recess 10 and hooking it on the outer periphery of the filter 5.

<Effects of the invention> Since the hand lamp of the present invention is constructed in this manner, the filter can be attached to the front surface of the hand lamp body by simply pushing it into the annular recess for filter attachment formed on the front surface of the hand lamp body.
Since the filter is substantially attached and supported to the hand lamp body only by a plurality of elastic locking pieces, it is easy to remove it, and overall, the attachment and detachment of the filter is extremely simple.

Moreover, the filter that is not in use can be easily removed and stored in the annular recess for filter storage formed on the back of the hand lamp body, and it can be stored securely, making it possible to prevent the filter from being lost or broken. This eliminates the risk of this happening and improves usability.

Therefore, the intended purpose can be achieved.
