[Detailed description of the device]

[0001]

This invention relates to simple binoculars.

[0002]

2. Description of the Related Art Conventionally, simple binoculars are generally foldable ones, for example, those in which an eyepiece plate and an objective lens plate are mounted on a desired substrate so as to be upright (actually No. 54- No. 5446), or a rotary plate having an eyepiece and an objective lens attached thereto is provided between a pair of left and right elongated plates so as to be freely foldable (see Japanese Utility Model Publication No. 36-16772).

[0003]

However, conventional simple binoculars can be folded and compacted and are convenient to carry, but on the other hand, the structure is complicated and the manufacturing is complicated, and also the strength is high. There was a problem and it was extremely poor in hobby.

This invention solves the problems of the prior art and is intended to provide simple binoculars that are not only extremely simple in structure and easy to manufacture, but also extremely durable and highly tasteful. To do.

[0005]

That is, according to the present invention, an outer cylinder 1 having a required length and diameter, an inner cylinder 4 rotatably fitted in the outer cylinder 1, and an inner cylinder 4 are provided. It is composed of a pair of cap bodies 11 on both sides which are fixed to both ends and rotatably hold both ends of the outer cylinder 1, and a pair of eyepieces 2 and an objective hole 3 are provided on both outer peripheral walls of the outer cylinder 1. On the other hand, the inner cylinder 4 is provided with an eyepiece lens 7 and an objective lens 8 corresponding to the eyepiece holes 2 and the objective holes 3, respectively.

[0006]

When the binoculars are used, one cap body 11 is rotated while gripping the outer cylinder 1, and each eyepiece hole 2 and the objective hole 3 are rotated.
Then, the eyepiece lens 7 and the objective lens 8 of the inner cylinder 4 are matched with each other for use. When not in use, the cap body 1
1 is rotated to rotate the inner cylinder 4 in a predetermined direction, and each eyepiece lens 7 and the objective lens 8 are housed in the outer cylinder 1 to be covered and protected.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below. Reference numeral 1 denotes an outer cylinder having a circular cross-section having a required length and diameter, and 2.3 a pair of outer cylinders formed on both outer peripheral walls at predetermined intervals so as to be orthogonal to the center line of the outer cylinder 1. The eyepieces and the objective holes 4 are inner cylinders having a substantially hexagonal cross section which are rotatably fitted in the outer cylinder 1, and 5 and 6 are both ends of the inner cylinder 4 corresponding to the eyepieces 2 and the object holes 3. A circular lens mounting hole formed on both outer peripheral walls of the parts, 7 and 8 are the lens mounting holes 5 and
An eyepiece lens and an objective lens provided inside the inner cylinder 4 via 6. Reference numeral 9 is a locking projection extending from both ends of each surface wall forming the inner cylinder 4, and 10 is an eyepiece lens 7 and an objective lens 8.
Is a slot-like engagement hole formed in the locking projections 9 of the other surface walls except the mounting surface wall. Reference numeral 11 denotes a pair of cap bodies which are rotatably fitted to both ends of the outer cylinder 1 and fixedly fixed to both ends of the inner cylinder 4, and each cap body 11 has an annular partition wall 12 on its inner surface. An end of the outer cylinder 1 is rotatably fitted and held in an annular groove 13 formed through the inner cylinder 4 via an engaging piece 15 in a locking wall 14 formed upright in the partition wall 12. The locking projection 9 is fixedly attached.

In the binoculars constructed as described above, one cap body 11 is rotated in a predetermined direction while the outer cylinder 1 is gripped by a hand, and the inner cylinder 4 is rotated, whereby each eyepiece hole 2 and the objective hole 3 are rotated. The eyepiece lens 7 and the objective lens 8 are made to coincide with each other and used. When not in use, the cap body 1
1 is rotated to rotate the inner cylinder 4 in a predetermined direction, and the eyepiece lens 7 and the objective lens 8 are respectively housed in the outer cylinder 1 for coating protection. In addition, when the binoculars are not used, in view of the shape that does not look like the binoculars,
It may be placed as a figurine on a desk, etc.
Since it has a double structure of 4, it has a very high strength and can be suitably used as a mounting table for relatively lightweight articles.

In the above embodiment, the inner cylinder 4 has a hexagonal cross section, but it is not limited to such a shape and may have a polygonal shape such as a circle, a quadrangle, or an octagon. Of course.

[0010]

According to the present invention, the outer cylinder 1 having a required length and diameter, the inner cylinder 4 rotatably fitted in the outer cylinder 1, and the inner cylinder 4 are constructed as described above. It is composed of a pair of cap bodies 11 on both sides which are fixed to both ends and rotatably hold both ends of the outer cylinder 1, and a pair of eyepieces 2 and an objective hole 3 are provided on both outer peripheral walls of the outer cylinder 1. On the other hand, the inner cylinder 4 is provided with an eyepiece lens 7 and an objective lens 8 corresponding to the respective eyepiece holes 2 and objective holes 3, so that the outer cylinder 1 is gripped. The eyepiece 7 and the objective lens 8 are aligned with the corresponding eyepieces 2 and 3 by an extremely simple operation of rotating the inner cylinder 4 in a predetermined direction by rotating the one cap body 11 while Also, it can be housed in the outer cylinder 1 for covering protection. Also, when not in use, not only can it be used as a figurine because of its shape that does not look like binoculars,
Since it has a double structure of the inner and outer cylinders 1 and 4, it is very strong and can be suitably used as a mounting table for relatively lightweight articles. Further, there is an advantage that the structure is extremely simple and the manufacturing thereof can be easily performed.
