It is a perspective view of a protection plate in an example.

In FIGS. 1 to 3 showing the first embodiment,
Reference numeral A denotes an opening 1 for inserting the lens 11 of the glasses C.
1 shows a bag-shaped lens-protecting cover body having the following. Inner layer 2 of this cover body A composed of a rear material 2a and a front material 2b
Is formed of a soft cloth, while the rear material 3a of the outer layer 3 is
The front member 3b is formed of a relatively strong and flexible sheet material such as cloth, synthetic resin, and leather. It is desirable that the rear material 2a and the front material 2b of the inner layer 2 be impregnated with silicone resin.

Relatively hard linings 4 and 4 are interposed between the rear members 2a and 3a and between the front members 2b and 3b, respectively, of the cover body A so that the cover maintains a bag shape. ing. A main elastic member B made of a leaf spring is interposed between the lining 4 and the two members 3a and 3b of the outer layer 3. The reversing force of the main elastic member B functions to pinch and protect the lens 11.

The main elastic member B is, as shown in FIGS.
It is a thin leaf spring that is cut into a substantially rectangular shape and bent. The member B has a shape in which an upper plate 6 and a lower plate 7 extend in substantially the same direction from both end edges in the width direction of the back plate 5 having an appropriate width, and the tip of the upper plate 6 is folded inward. The holding plate 8 is provided. The tip of the clamping plate 8 is an L-shaped auxiliary elastic member 1.
Appropriate elasticity is applied to the inner surface of the long piece 12a via the lining 4 and the inner layers 2a, 2b. The auxiliary elastic member 12 is also made of a thin leaf spring, and the main elastic member B
Both are housed inside a bag-shaped cover body A.

The upper plate 6 of the main elastic member B has a concave portion 9 which can be elastically inverted. As shown in FIGS. 2, 4 and 5, when the concave portion 9 is in a posture in which the concave surface is directed toward the lower plate 7, the opening 1 on the opposite side facing the back plate 5 is provided with the member B. It is kept open by elasticity. On the contrary, when the convex surface is inverted upward as shown in FIGS. 3 and 6, the opening 1 is kept closed with an appropriate elasticity.

Inside the boundary portion located between the upper plate 6 and the back plate 5 of the main elastic member B, a lower projection 6a on the far side and a higher projection 6b closer to the opening are formed by a pull-out method. Are provided at intervals in the longitudinal direction of the
a1 and 6b1 are pierced. The short piece 12b of the L-shaped auxiliary elastic member 12 is the back plate 5 of the U-shaped main elastic member.
The tip of this short piece is held between the boundary and the low protrusion 6a unless it receives a strong external force, and the tip of this short piece is low if it receives such an external force. The projection 6a gets over the projection 6a, hits the projection 6b, and is supported by the projection 6b. That is, the tip of the short piece 12b is selectively locked by the low or high projection. The transition heel portion (bent portion) from the long piece 12a to the short piece 12b is pressed into the (other) boundary between the lower plate 7 and the back plate 5. The elongated piece 12a and the inner lining 4 are sandwiched between the front members 2b and 3b of the inner and outer layers.

As is clear from the above description, the holding plate 8
Is located in front of the back plate 5, and the lower plate 7 of the main elastic member B is much shorter than the upper plate 6. The upper plate 6 having the concave portion 9 and the sandwiching plate 8 obtained by folding the upper plate 6 are interposed between the rear members 2a and 3a of the inner and outer layers of the bag-shaped cover body A. Auxiliary elastic member 1
The two long pieces 12a have a heel portion that transitions to the short piece 12b, and the heel portion is fitted in a corner between the back plate and the lower plate. A long piece 12a substantially parallel to the rear side of the cover extends from the back plate by substantially the same distance as the upper plate 6, and the cover A
Is sandwiched between the front members 2b and 3b. The front lining 4 is interposed between the long piece 12 a and the front material 2 b of the inner layer 2.

In the second embodiment shown in FIGS. 8 and 9, a protection plate 13 made of relatively hard plastic is added. The protection plate 13 is interposed between the rear lining 4 and the sandwiching plate 8 at the back near the back plate, and between the lining 4 and the rear material 3a at the entrance near the entrance. Intervening between them.

The operation of each part when using the protective cover of the present invention is as follows. That is, first, when the main elastic member B contained in the bag-shaped cover body A is in the first posture as shown in FIG. 2, the opening 1 is half-open, and the lens 11 of the glasses C is inserted. I can do it. Recess 9
Due to the elasticity of the elastic member B projecting toward the front side of the cover body A, this half-open position is maintained independently and stably unless it receives any external force.

When the lens 11 is inserted deeply through the opening 1, the lens is brought into a closed position protruding backward from the front side of the cover with respect to the concave portion 9 of the elastic member B as shown in FIG. Invert as shown in FIG. The spectacle user can safely carry the lens by storing the lens and putting the spectacles together with the protective cover in the closed position in a breast pocket or the like.

Next, when the protective cover is removed and the spectacles are used, the cover is returned to the position shown in FIG. 2 by suppressing the concave portion 9 of the main elastic member B. Although the lens can be pulled out even in this posture, the lens or the elastic member may be damaged due to excessive force applied. Therefore, the spectacle user can make the protective cover of the present invention take a wide open posture as shown in FIG.
More specifically, the front side portion near the opening of the bag-shaped body may be operated with a fingertip in a direction to separate the front side portion from the rear side portion, so that the rear edge of the auxiliary elastic member 12 resiliently moves over the low protrusion 6a. As a result, the protection cover is shifted to the wide open position (FIG. 7). After the lens is taken out, the state shown in FIG. 7 may be left as it is, but it may be better to return the lens to the half-open position shown in FIG. For this purpose, the front and rear both members near the opening 1 may be pressed in a direction approaching each other, so that the back end of the auxiliary elastic member 12 separates from the high protrusion 6b and rides over the low protrusion 6a to the original position. Return to.

For the next lens insertion and storage, it is more convenient to use the wide open position. In this case, the lens is half-opened after the lens is stored and then restored to the closed position shown in FIG.

The protective plate 13 in the second embodiment reduces the friction between the sandwiching plate 8 and the lining 4 to smoothly open and close the cover, and also prevents the lens frame of the glasses C from catching on the sandwiching plate 8. I try not to. Holding plate 8 and upper plate 6
Bags 15a and 15b for accommodating the long pieces 12a of the auxiliary elastic member 12 are adhered to the inner and outer linings 4 and 4, respectively, so as not to shift. Furthermore, the ring 17 attached to the left and right bag-shaped covers A, A
Connect both ends of the chain 16 and form a strip,
When the spectacles are stored, the buffer plates 14 and 14 are inserted through the inside of the auxiliary elastic member 12 so that the lens 11 of the spectacles C or the lens 11 or The frame is prevented from contacting the auxiliary elastic member 12 and being scratched.

[0024]

While the long piece 12a and the holding plate 8 are overlapped, the spectacles C are attached to the holding plate 8 by the plastic protection plate 13 so that the eyeglasses C and the inner inner material 2
a between the inner surface member 2a and the outer inner surface member 2b.
The holding plates 8 and the upper plate 6 and the bag bodies 15a and 15b for accommodating the long pieces 12a of the auxiliary elastic members 12 are respectively bonded to the inner and outer linings 4 and 4, respectively.
Also, the position of the long piece 12a of the auxiliary elastic member 12 does not shift.
Further, a ring 17 attached to the left and right bag-shaped covers A, A
At the same time, both ends of the chain 16 are connected, and a flexible plastic plate is formed into a strip shape. The lens 1 of the eyeglasses C is inserted and held inside.
Various effects that have not existed in the past can be expected, such as preventing the one or the frame from hitting the auxiliary member and causing scratches. In short, the advantages of the protective cover for spectacle lenses according to the present invention include:
The opening of the bag-like body can be opened larger than before, the lens can be easily inserted and removed, and the operation to take a large open position is easy, and the structure for that is overly complicated But not expensive.
