Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a binocular or telescope lens mounting device made of a sheet-like or plate-like member.

An example of a structure for attaching lenses to the main body of binoculars or telescopes made of sheet-like or plate-like members is disclosed in Japanese Utility Model Publication No. 56-50491. This consists of a pair of ring-shaped mounting bodies, and by inserting a protrusion on the other mounting body into a hole on one mounting body, the lens is clamped and fixed between the pair of mounting bodies. It is something. The clamped lens is prevented from moving in the radial direction by fitting the lens into a recess provided on the opposing surface of one mounting body. Therefore, the structure is complicated and the cost increases, and the pair of mounting bodies are joined by simply pushing the protrusion of one mounting body into the hole of the other mounting body. There is also a risk that the mounting body may separate and the lens may fall off.

An object of the present invention is to provide a lens mounting body that allows a lens to be easily and firmly mounted to a main body made of a sheet-like or plate-like member.

The present invention has a plurality of recesses on the periphery of a lens mounting hole provided in a case body made of a sheet-like or plate-like member, and a ring-shaped mounting body with a diameter larger than the mounting hole is erected. A plurality of protruding pieces that are shallow and capable of elastic deformation are inserted from one side of the case body to the other side at the position of the recess, and a lens is fitted inside the protruding pieces from the other side of the case body and protrudes. The lens is locked inside the locking projection provided on the inner surface of the piece, and when the lens is stacked on the periphery of the mounting hole that protrudes inwardly from the projection piece, the mounting body and the lens are attached to the periphery. It is characterized by being formed by holding the .

To explain this lens mounting device with reference to the embodiment shown in the drawings, 1 is a case body of binoculars made of slightly thick paper or hard synthetic resin board;
Attachment holes 2 for the eyepiece and objective lens in the opposite part.
, and a plurality of recesses 3 are provided on the inner peripheral edge of the mounting hole 2 .

Reference numeral 4 denotes a ring-shaped mounting body placed on the outer surface of the main body 1, overlapping the mounting hole 2, which has a larger diameter than the mounting hole 2, has a size that can cover the recess 3, and has an inner diameter that is larger than the lens. is smaller than the diameter of 5 is the mounting body 4 on the surface facing the main body 1 of the mounting body 4.
A plurality of protruding pieces for supporting the lens are installed upright in the radial middle part of the lens, and are inserted into each recess 3 and inserted into the mounting hole 2. These are made of a hard synthetic material that can be slightly elastically deformed. It is made of resin, rubber, or metal, and has a locking protrusion 6 for locking the lens on the inner surface of its tip. The protruding piece 5 may be formed integrally with the mounting body 4, or may be formed separately from the mounting body 4.
It is optional, such as attaching it to The thickness of the protruding piece 5 in the depth direction of the recess 3 is thinner than the depth of the recess 3, so that the inner peripheral edge of the mounting hole 2 slightly protrudes inward of the protruding piece 5. The reason why the protruding piece 5 is provided at a position away from the inner peripheral edge of the mounting body 4 is to cover the peripheral edge of the mounting hole 2 with the mounting body 4.
The position of the protruding piece 5 with respect to the mounting body 4 can be set arbitrarily.

In this embodiment, six recesses 3 and six protruding pieces 5 are formed, and three of the protruding pieces 5 are provided with protrusions 6. The number of protrusions 6 is arbitrary. Further, it is suitable that the tip of each protruding piece 5 be formed into an inwardly inclined slope 7 to facilitate attachment of the lens, but this structure may be formed arbitrarily. When the tip of the protrusion piece 5 is formed into a slope 7, in the case of the protrusion piece 5 having a protrusion 6, the protrusion 6 is also made into a continuous slope. In addition, the protrusion 6
Even if only the surface is sloped, the attachment of the lens can be facilitated. 8 is fitted inside each protruding piece 5, is locked inside each protruding part 6, and is overlapped on the edge of the mounting hole 2 that protrudes further inward than each protruding piece 5, This is a lens attached to the main body 1.

The lens 8 is attached by placing it on the upper end of each protrusion piece 5 and pressing it lightly, so that the protrusion piece 5 having the protrusion 6 is elastically deformed slightly outward and fitted into the inner side of the protrusion 6.

Therefore, it is suitable to form three or more protruding pieces 5, but if the width of the protruding pieces 5 in the circumferential direction of the lens 8 is increased, two protruding pieces 5 can form the lens 8.
can also be fixed. If three or more locking protrusions 6 are provided on the protruding piece 5, it is suitable for stably supporting the lens 8, but when as many as six protruding pieces 5 are provided as in the embodiment, Since each protrusion piece 5 prevents the lens 8 from moving in the radial direction, even two protrusions 6 can support the lens 8 stably.

When the lens 8 becomes thick, a fifth lens is added around its periphery.
As shown in the figure, it is also possible to provide a stepped portion to make it thinner and to lock the protrusion 6 to this portion.

As described above, the present invention provides a ring-shaped mounting body 4 in the recess 3 on the periphery of the mounting hole 2 provided in the main body 1.
A protruding piece 5 is inserted into the lens 8, and a lens 8 is fixed to the inside of each protruding piece 5. Since the lens 8 is fixed by being locked inside a plurality of locking protrusions 6 provided on the inner surface of the tip of the protruding piece 5, there is no fear that the lens 8 will be separated unnecessarily, and the lens 8 can be securely fixed. It is possible to fix the lens 8 to. In addition, since the lens 8 overlaps the periphery of the mounting hole 2 that protrudes inwardly more than the protruding piece 5,
The lens 8 and the periphery of the attachment hole 2 prevent the protruding piece 5 from separating from the main body 1. Therefore, the lens 8 can be securely fixed without fear of unnecessarily separating the mounting body 4 from the main body 1.

And a ring-shaped mounting body 4 having a protruding piece 5
Since the number of parts is small, it is easy to reduce costs.In addition, when attaching the lens 8, insert the protruding piece 5 into the recess 3, press the lens 8 lightly, and remove the protruding piece 5. Since the lens 8 is fitted inside the plurality of protruding pieces 5 by elastic deformation and is locked to the locking protrusion 6, the operation of attaching the lens 8 is extremely simple and easy.

If the tips of the protruding pieces 5 are sloped as in the embodiment, they serve as guides when the lens is pushed in, making it easier to attach the lens 8.

According to the present invention, the lens can be attached to the case body using only a ring-shaped attachment member having a protruding piece, and costs can be easily reduced. Then, by locking the lens to the protrusion provided inside the protruding piece, the fixed state of the lens is maintained, and by locking the lens to the periphery of the mounting hole, the mounting body is separated from the case body. This makes it possible to securely attach the lens to the case body.
