[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens mounting structure for mounting a lens with a stopper.

[0002]

2. Description of the Related Art As a conventional lens mounting structure for mounting a lens by a fastener, a lens mounting structure of a two-point frame as shown in FIG. 3 is known (see Japanese Utility Model Laid-Open No. 61-81630).

That is, the mounting structure has a metal fitting 104 having a mounting surface that substantially matches the side surface of the lens 101, and a metal member (not shown) interposed between the metal fitting 104 and the side surface of the lens 101. And a leaf spring.

[0004]

However, in the above-described conventional mounting structure, since the member to be interposed is the metal leaf spring, the lens 101 and the stopper 104 are attached.
Since the cushioning property (absorption of external force) between and is weak, the lens 101 may be chipped.

Further, due to a dimensional error between the lens 101 and the stopper 104, sufficient fixing strength cannot be obtained, and the lens 101 may wobble vertically during use.

Further, since the interposed member is a leaf spring, even if it is seen from the outside, the decorative effect cannot be obtained, and the appearance quality may be deteriorated.

The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a lens mounting structure capable of preventing chipping or wobbling of a lens and enhancing a decorative effect.

[0008]

In order to achieve the above object, in the present invention, in a lens mounting structure in which a lens is attached by a stopper, a side surface of the lens is provided between the stopper and the lens. having a mounting surface that substantially matches, than the metal comprising the intermediate member of low rigidity, the intervening instrumentation member
And an engaging portion that engages the stopper with the interposing member.
It is characterized in that it is provided on at least one of the metal fittings .

[0009]

In the present invention having the above structure, since the interposing member interposed between the stopper and the lens is a member having a rigidity lower than that of metal, the interposing member is less than the conventional metal leaf spring. The cushioning property is enhanced and the lens is prevented from being chipped. In addition,
The interlocking part that engages the member and the metal stopper with the interposing member
Since it is provided on at least one of the metal fittings, the intervention member
It does not move out of position.

Further, since the member having a high cushioning property is interposed, the lens is firmly fixed to the stopper and it is possible to prevent the lens from wobbling during use.

Further, the decorative effect can be enhanced by the color and design of the interposing member itself.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the illustrated embodiments.

FIGS. 1 and 2 show a lens mounting structure according to an embodiment of the present invention, which is a two-point frame lens mounting structure as shown in FIG.

That is, the left and right lenses 1 and 1 are provided with stoppers 4 and 5 at two locations of the bridge 2 portion and the wisdom portion 3 respectively.
The lenses 1 and 1 are attached using.

The stopper 4 at the tip 3 has a bolt 7 inserted through a hole 6 formed in the lens 1, a nut 8 screwed into the bolt 7, and a hole 9 through which the bolt 7 is inserted. A metal fixing piece 10 which is provided at one end and is fixed to the lens 1 by inserting a bolt 7 together with the hole 6 of the lens 1 and screwing a nut 8 and a rear surface of the other end of the fixing piece 10. A metal locking piece 11 whose side surface is fixed by brazing or the like and whose surface is fixed to the wisdom 3 by brazing or the like;
Made of.

Between the locking piece 11 and the lens 1, the lens 1
A member having a mounting surface that substantially matches the side surface of the member, which is less rigid than metal, such as plastic, rubber, elastomer,
An interposition member 12 made of wood or the like is provided. That
The interposition member 12 is provided on both sides in the vertical direction with the locking piece 11.
The locking portion 12a for preventing the shift is laterally provided on the locking piece 11.
Locking parts 11a are provided to prevent misalignment on both sides.
Has been.

The operation of this embodiment having the above structure will be described below.

In this embodiment, since the interposition member 12 interposed between the locking piece 11 of the stopper 4 and the lens 1 is a member having a rigidity lower than that of metal, it is made of the conventional metal. The cushioning property is higher than that of the leaf spring of FIG. Further, the interposing member 12 and the stopper 4 are locked.
The locking portions 11a and 12a are attached to the interposing member 12 and the stopper fitting 4
Since the locking pieces 11 are provided respectively, the interposition member 12 is
It does not deviate from the fixed position.

Further, since the member having a high cushioning property is interposed, the lens 1 is firmly fixed to the stopper 4 and it is possible to prevent the lens 1 from wobbling during use.

The decorative effect can be enhanced by incorporating a color or a design into the interposing member 12.

In the present embodiment, the intervening member uses the clasp of the clasp, but the invention is not limited to this, and the clasp may be applied to the clasp of the bridge.

[0022]

[Effects of the Invention] As described above, according to the present invention,
Since the interposing member interposed between the stopper and the lens is a member having a rigidity lower than that of metal, the cushioning property is improved as compared with the conventional metal leaf spring and the like, and the lens is prevented from being chipped. Also, make sure that the locking part that locks the interposer
Since it is provided on at least one of the interposing member and the stopper,
The interposition member does not shift from the predetermined position.

Further, since a member having a high cushioning property is interposed, the lens is firmly fixed to the stopper and it is possible to prevent the lens from wobbling during use.

The decorative effect can be enhanced by the color and design of the interposing member itself.
