Description

[Detailed description of the invention] This invention relates to a compact illuminated loupe that can also be used as a hand mirror.

Conventionally, as a magnifying glass with illumination, one shown in FIG. 1 is known. This illuminated magnifying glass has a structure that combines a magnifying glass A, which has a convex lens 2 attached to the top of a skirt part 1, and a cylindrical portable light B, which is equipped with a power battery 4, a light bulb 5, a switch 6, etc. The tip of a portable electric lamp B equipped with a light bulb 5 is fitted into an illumination hole 3 of a skirt part 1. As is clear from the figure, the light from the light bulb 5 is guided into the skirt portion 1 and illuminates a map or the like placed under the skirt portion 1. This illuminated map etc. can be enlarged and viewed using the convex lens 2.

The biggest drawback of this type of conventional illuminated loupe is its shape, in which the large diameter part of the loupe A and the long tube part of the electric lamp B are perpendicular to each other, and this shape is extremely difficult to carry and also difficult to store. Significantly bad. In particular, when the loupe A has a large diameter, the above-mentioned drawback becomes even more noticeable. This poor practical usability, such as portability and storage, is thought to be the reason why this type of illuminated loupe is not so popular.

This idea was devised in view of the problems with the conventional technology mentioned above, and its purpose was to create a compact design with good portability and storage, as well as a highly practical design that could be used as a hand mirror as an additional function. The purpose is to provide a magnifying glass with illumination.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

2A and 2B show the appearance of the illuminated loupe according to this invention, and FIG. 3 shows its internal structure. The outer structure of this illuminated magnifying glass consists of a main housing 20 and a sub-casing 30. The main housing 20 forms the main body of the illuminated magnifying glass, and the secondary housing 30 has a built-in power battery 32.

The outer ring shapes of the main housing 20 and the secondary housing 30 are the same,
The base portions 21 and 31 are formed protruding from a circular portion and a portion of its outer periphery, and are formed in a flattened shape with an appropriate height. The bases 21 and 31 of both the casings 20 and 30 are connected by a hinge 40 so as to be openable and closable as shown in FIGS. 2A and 2B.

The main housing 20 has the base 21 integrally provided in a circular frame 22 with open upper and lower sides, and a magnifying semi-transparent mirror 23 is fixed to the upper surface of the frame 22. The magnifying semi-transparent mirror 23 includes a semi-transparent mirror 23a having a flat upper surface and a reflectance of about 50%, and a magnifying lens 23b made of a Fresnel lens superimposed on the lower surface of the semi-transparent mirror 23a. This semi-transparent mirror 23
a and the Fresnel lens 23b can be integrally formed. Further, a light bulb 24 for illuminating the inside of the frame 22 is attached to the base 21 side inside the main housing 20.

The light bulb 24 and the power battery 32 are electrically wired via a switch 33. The switch 33 is attached to the base 31 of the sub-casing 30, and is turned on and off in conjunction with the opening/closing operation of the sub-casing 30 around the hinge 40. In other words, the button 33a of the switch 33
protrudes from the surface facing the main housing 20, and the second
As shown in FIG.
When pressed to 0, switch 33 turns off and light bulb 2
4 goes out. Further, as shown in FIG. 2B, when the sub-casing 30 is opened and the lower surface side of the frame 22 of the main casing 20 is exposed, the switch 33 is turned on and the light bulb 24 is turned on.

Although not shown in the detailed paper, a holding mechanism with an elastic click that operates with an articulated feel is provided to lightly hold the main housing 20 and the secondary housing 30 in the closed state. In addition, the sub-casing 30
has a lid structure for replacing the battery 32.

As is clear from the above configuration explanation, the main casing 2
0 and the sub-casing 30 are closed, the overall shape is extremely compact, and there is no irregularly shaped protrusion like in the conventional case, so it is excellent in portability and storage. Further, in this state, the internal light bulb 24 is off, and the inside of the frame portion 22 is dark. Therefore, the magnifying semi-transparent mirror 23 acts as a mirror and can be used as a hand mirror.

When the main housing 20 and the secondary housing 30 are opened, the light bulb 24 lights up and the lower part is illuminated from inside the frame 22. Therefore, if a map or the like is placed at the bottom of this frame portion 22, the map will be brightly illuminated by the light from the light bulb 24. In this state, the magnifying semi-transparent mirror 2
The semi-transparent mirror 23a of No. 3 acts as a light transmitting plate, and the magnifying lens 23b allows an enlarged view of the map below.

Note that the magnifying lens 23b is not limited to a Fresnel lens, but when a Fresnel lens is used, the overall thickness can be reduced and the structure can be made compact, which is particularly advantageous when designing a lens with a large area.

As explained in detail above, the illuminated magnifying glass according to this invention has a compact shape with good portability and storage, since the magnifying glass part and the power supply part are separated into the main casing and the secondary casing, which can be opened and closed. can. Furthermore, by using a magnifying semi-transparent mirror and having a structure in which the main casing can be closed, it can be used as a hand mirror, further increasing the practicality of this type of loupe.
