JP7659145B2 - Impact Resistant Glasses - Google Patents

Description

The present invention relates to impact-resistant eyeglasses that can absorb shock, and more specifically to impact-resistant eyeglasses that can absorb shock by cushioning members attached to the temples.

An eyeglass frame generally has a front portion and a pair of temples rotatably attached to both ends of the front portion.
These temples are rotatably attached to the ends of the front portion via hinges or the like, and can be folded up when not in use.
However, there are also glasses that do not use hinges, but rather have the front and temple parts integrated with a super-spring metal to rotate.

Meanwhile, glasses are subject to a large shock when playing sports or the like, for example, when a baseball ball accidentally hits the face.
Furthermore, for example, if a person wears glasses and bumps into something or falls, the glasses will be subjected to a large shock.
This causes the front and temples to receive the same amount of impact, which is then transmitted to the face.
In extreme cases, the face may become injured.
In particular, since the temples are attached so as to run along the sides of the face, when an impact is received, the impact is felt over the entire side of the face, including the temples.
For this reason, eyeglasses that can withstand impacts have been developed.

For example, in Patent Document 1, when an impact is received, the end piece deforms to absorb the external force of the impact. For this reason, the end piece has a unique shape that is deformed into a coil.

In addition, in Patent Document 2, the inner cushioning piece of the two elastic wires on the inside and outside of the end piece is folded back in a hairpin shape to form a first convex bending section and a second convex bending section, which can absorb external shocks.

Moreover, in Patent Document 3, a flexible connecting member is provided between the end piece and the temple.
When the eyeglass frame receives an impact, the flexible connecting member is elastically deformed and can be detached from the guide groove of the temple.

Furthermore, Patent Document 4 discloses a structure in which decorative blocks are arranged in a daisy-chain in a portion of a temple, and an elastic core rod is inserted into mounting through holes provided in these decorative blocks.
The temples themselves have shock absorbing properties.
However, in the event of an impact, the temples come into direct contact with the sides of the face, placing a great strain on the face.

The present invention has been developed to solve the problems associated with the prior art.
That is, an object of the present invention is to provide impact-resistant spectacles A in which cushion pads (members) attached to the temples prevent the temples from directly hitting the face and cushion the impact.

As a result of extensive research conducted by the inventors based on the above technical background, they discovered that by providing cushion pads with gaps in the temples, the cushion pads can absorb shock and minimize the impact being directly applied to the face, and this discovery led to the completion of the present invention.

That is, the present invention provides (1) a pair of impact-resistant spectacles A having a cushion pad 1 on a temple 2, the temple 2 being formed with a through hole 21 for attachment, the cushion pad 1 being removably fitted into the through hole 21 for attachment,
The cushion pad 1 consists of a block-shaped inner wall portion 11, a rib-shaped outer wall portion 12, and a connecting base 13 connecting them, and the connecting base 13 is formed to be smaller and thinner than the block-shaped inner wall portion 11 and the rib-shaped outer wall portion 12, and is present in impact-resistant glasses A in which the block-shaped inner wall portion 11 has an open space portion 11A in the vertical direction .

The present invention also resides in ( 2 ) the impact resistant spectacles A described above in 1 , in which the connecting base 13 is fitted into the mounting through hole 21.

The present invention also resides in ( 3 ) the impact resistant spectacles A described above in 1 , wherein the through space 11A has a space width that gradually decreases toward the rear.

The present invention also resides in ( 4 ) the impact resistant spectacles A described above in 1, wherein the cushion pads 1 are made of synthetic rubber.

The present invention also resides in ( 5 ) the impact resistant spectacles A described above in 1 , wherein a small through hole P is provided in the connecting base 13 of the cushion pad 1, penetrating from the rib-shaped outer wall portion 12 through the block-shaped inner wall portion 11.
The present invention also resides in (6) the impact resistant spectacles A as described in the above item 1, in which a support wall W is provided in the through space 11A.

In addition, any suitable combination of the above (1) to (7) may be adopted as long as it is in accordance with the objectives of the present invention.

1) In the impact-resistant spectacles A of the present invention, the temples 2 are formed with through-holes 21 for attachment, and the cushion pads 1 are removably fitted into the through-holes 21 for attachment. Therefore, even if an impact is applied to the spectacles frame from the outside, the impact can be absorbed.
Moreover, if the cushioning effect weakens or the cushion pad 1 becomes dirty, it can be replaced with a new one.
At this time, replacement can be easily performed by pulling and removing the cushion pad 1 from the mounting through hole 21.
It is also possible to use the product with the cushion pad 1 removed.
In this case, since ventilation is possible through the mounting through holes 21, there is an advantage that it is cool and sweaty.

2) The impact-resistant spectacles A of the present invention are comprised of a block-shaped inner wall portion 11, a rib-shaped outer wall portion 12, and a connecting base portion 13 connecting them. The connecting base portion 13 is smaller and thinner than the block-shaped inner wall portion 11 and the rib-shaped outer wall portion 12, so that the rib-shaped outer wall portion 12 acts as a brim (stopper) to accurately prevent the cushion pad 1 from falling off.

3) In the impact-resistant spectacles A of the present invention, the connecting base 13 is fitted into the mounting through-hole 21, making it easy to mount the cushion pad 1 and maintaining the fitting force when mounted.

4) In the impact-resistant spectacles A of the present invention, the block-shaped inner wall portion 11 is provided with a through space portion 11A in the vertical direction, which provides cushioning properties and allows air to pass through, resulting in a heat dissipation effect and minimizing sweating and the like.

5) In the impact-resistant spectacles A of the present invention, the space width of the through space portion 11A gradually decreases toward the rear. Therefore, when an impact is received and the cushion pad 1 hits the side of the face, a component force is generated which acts (rearward) to prevent the spectacles from coming off.
Furthermore, in the case of the front portion 3 having the hood portion 31, a gap is unlikely to occur between the front portion 3 and the face.

6) In the impact-resistant eyeglasses A of the present invention, the cushion pad 1 is made of synthetic rubber, so it comes into soft contact with the skin of the face, feels good to the touch, and is not slippery.

7) In the impact-resistant spectacles A of the present invention, a small through hole P is provided in the connecting base 13 of the cushion pad 1, penetrating from the rib-shaped outer wall portion 12 to the block-shaped inner wall portion 11, so that air can pass freely through the cushion pad 1.
Therefore, the heat dissipation function can be exhibited, and stuffiness due to sweat, etc. is less likely to occur, for example, while playing sports.

The impact-resistant spectacles A of the present invention exhibit more effective impact protection, particularly when used for sports.
An embodiment of the present invention will be described below.

(First embodiment)
FIG. 1 is a perspective view showing impact-resistant spectacles A (with cushion pad 1 removed) according to an embodiment of the present invention, and FIG. 2 is a plan view showing impact-resistant spectacles A (with cushion pad 1 removed) according to an embodiment of the present invention.

FIG. 4 is a plan view showing the impact resistant eyeglasses according to the embodiment of the present invention, and FIG. 5 is a side view thereof.

The impact-resistant spectacles A of the present invention comprise a front portion 3 having a lens portion R (for myopia, hyperopia, sunglasses, etc.) and a temple 2 rotatably attached thereto, and the temple 2 is provided with a cushion pad 1.
This cushion pad 1 is removable, so it can be replaced with a new one or with one of a different shape.
In the example shown in this figure, the front portion 3 is provided with a hood portion 31 for keeping out pollen, etc.

The impact-resistant spectacles A of the present invention exhibit more effective impact protection, particularly when used for sports.
In addition, it is possible to attach an inner lens frame to the bottom of the hood portion, but we will not go into detail on this point.

(Mounting through hole)
First, the temple 2 of the impact resistant spectacles A is provided with a through hole 21 for attaching the cushion pad 1 .
The mounting through hole 21 is formed along the length of the temple 2 and has a long and narrow rectangular shape.
As will be described later, this mounting through hole 21 is a hole into which the cushion pad 1 (more specifically, the connecting base portion 13 of the cushion pad 1) is fitted for mounting.
Incidentally, the connecting base 13 , which will be described later, has a long and narrow rectangular shape that corresponds to the mounting through hole 21 .

FIG. 6 is a perspective view showing a cushion pad of impact resistant eyeglasses according to an embodiment of the present invention, FIG. 7 is a plan view thereof, and FIG. 8 is a side view thereof.
FIG. 9 is a cross-sectional view showing a state in which a cushion pad of impact resistant eyeglasses according to an embodiment of the present invention is attached to a temple 2. As shown in FIG.

The cushion pad 1 of the present invention is intended to prevent a direct impact on the face when the eyeglasses are subjected to an impact for some reason while the eyeglasses are being worn.
The cushion pad itself can be interposed between the temple 2 and the face to sufficiently mitigate the impact.
The cushion pad 1 is an independent member separate from the temple 2, and by fitting it into the temple 2, the temple 2 of the impact-resistant spectacles A becomes impact-resistant.

The cushion pad 1 is made of a flexible material, such as synthetic rubber, raw rubber, silicone resin, or the like.
When the cushion pad 1 is fitted into the through hole 21 of the temple 2, the cushion pad 1 can be fitted by utilizing the flexibility of the cushion pad 1 itself.
The cushion pad 1 is formed elongated and larger than the through-hole 21 for attachment of the temple 2 .

More specifically, the cushion pad 1 comprises a block-shaped inner wall portion 11, a rib-shaped outer wall portion 12, and a connecting base portion 13 connecting these (see Figs. 6 and 7).
The connecting base portion 13 is formed to be smaller and thinner (having a smaller vertical cross section) than the block-shaped inner wall portion 11 and the rib-shaped outer wall portion 12 .
The connecting base 13 is narrower than the block-shaped inner wall portion 11 and slightly narrower than the rib-shaped outer wall portion 12 (see FIG. 9).

That is, the block-shaped inner wall portion 11 and the rib-shaped outer wall portion 12 are formed so as to protrude outward from both ends of the connecting base portion 13 .
The connecting base 13 is set to be the same size as or slightly smaller than the attachment through-hole 21 of the temple 2 .

Therefore, the connecting base 13 can enter the mounting through hole 21 .
The rib-like outer wall portion 12 has a cross section in the vertical direction larger than that of the connecting base portion 13 and appears to be formed just like a rib around the connecting base portion 13 .
As described later, the cushion pad 1 has a through space 11A formed in the block-shaped inner wall portion 11 in the up-down direction, so that a relatively gentle cushioning force is obtained in the inward and outward directions (horizontal direction).
The size of the rib-shaped outer wall portion 12 is larger than the mounting through hole 21, so that it is difficult for it to slip outward.

In other words, when the cushion pad 1 is fitted into the temple 2, the rib-shaped outer wall portion 12 serves to prevent the cushion pad 1 from slipping out.
The rib-shaped outer wall portion 12 is thin, so that it has good flexibility and bendability and can easily pass through the mounting through hole 21 by deformation.
The block-shaped inner wall portion 11 is formed in a block shape with a greater depth (horizontal width) than the rib-shaped outer wall portion 12 , and it is preferable that the vertical width is smaller than the vertical width of the temple 2 .

The block-shaped inner wall portion 11 is spindle-shaped when viewed from above and gradually becomes smaller toward the rear.
There is a through space in the vertical direction.

The through space 11A is formed by hollowing out the block-shaped inner wall portion 11 in the vertical direction, and in the figure, has a spindle shape that follows the outer shape of the block-shaped inner wall portion 11.
That is, the width of the through space 11A gradually decreases rearward.
Therefore, when an impact is received and the cushion pad 1 hits the side of the face, a component force is generated, which acts (rearward) so as to prevent the eyeglasses from coming off.
The through space 11A provides an appropriate cushioning effect (elasticity).
Incidentally, by putting some kind of stuffing (for example, sponge) in this through space 11A, the degree of cushioning of the cushion pad 1 itself can be changed.
Next, the procedure for fitting the cushion pad 1 to the temple 2 will be briefly described.

1) First, hold the cushion pad 1 and the temple 2 of the spectacles in each hand, and align the rib-shaped outer wall portion 12 of the cushion pad 1 with the mounting through hole 21 of the temple 2 to perform positioning.
2) Then, the rib-shaped outer wall portion 12 is pressed firmly into the attachment through-hole 21 of the temple 2 .
As a result, the rib-shaped outer wall portion 12 deforms and shrinks, and enters the mounting through hole 21 .
3) When pressed further, the rib-shaped outer wall portion 12 escapes from the mounting through-hole 21 and expands to the opposite side (outside).
At this point, the block-shaped inner wall portion 11 and the rib-shaped outer wall portion 12 sandwich the thickness portion of the temple 2 from both sides.

The connecting base 13 fits into the mounting through hole 21 of the temple 2, and both sides of the temple 2 are sandwiched between the block-shaped inner wall portion 11 and the rib-shaped outer wall portion 12, so that the cushion pad 1 is securely attached via the mounting through hole 21 of the temple 2.
By the way, when glasses are used, they may become dirty or their cushioning may deteriorate. In such a case, it becomes necessary to replace the glasses with new ones.

When removing the cushion pad 1 from the temple 2 for replacement in this manner, the rib-shaped outer wall portion 12 is lifted from the temple 2 from the outside with a fingernail or the like so as to peel it off slightly, and the block-shaped inner wall portion 11 is pulled strongly.
Then, the rib-shaped outer wall portion 12 enters the mounting through hole 21 and passes through it to be released to the outside together with the connecting base portion 13.
The cushion pad 1 is now removed from the temple 2.

This removal operation is the opposite of the above-mentioned operation of fitting the cushion pad 1 into the temple 2.
The above-described operation of attaching or detaching the cushion pad 1 using fingers can be easily performed by utilizing the cushioning properties (flexibility) of the cushion pad 1 itself.
Next, another embodiment will be described.

Second Embodiment
FIG. 10 is a perspective view showing a cushion pad for impact resistant eyeglasses according to another embodiment of the present invention, and FIG. 11 is a plan view thereof.
In this embodiment, a small through hole P is provided in the connecting base 13 of the cushion pad 1, penetrating from the rib-shaped outer wall portion 12 through the block-shaped inner wall portion 11.
Since the cushion pad 1 has such small through holes P, air can pass through them freely.
It has a heat dissipation function, and for example, it is less likely to become stuffy due to sweat while playing sports.

Third Embodiment
FIG. 12 is a perspective view showing a cushion pad of impact resistant eyeglasses according to still another embodiment of the present invention.
A support wall W as shown in the figure is provided in the through space 11A of the block-shaped inner wall portion 11 of the cushion pad 1, thereby dividing the through space 11A into a plurality of spaces.
By providing such a support wall W, it is possible to increase the degree of cushioning property of the block-shaped inner wall portion 11.

Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above-described embodiment, and various modifications are possible.
For example, it is possible to impart decorativeness to the ribbed outer wall portion 12 of the cushion pad 1 .
The rib-like outer wall portion 12 of the cushion pad 1 is the portion exposed to the outside, and any decoration applied thereto can be easily seen by others.
Therefore, in the cushion pad 1, the ribbed outer wall portion 12 can be utilized to provide decorative properties in addition to cushioning properties.
Furthermore, the attachment through-hole 21 of the temple 2 is preferably located at a portion of the temple 2 corresponding to the temple, but the position can be freely determined along the length of the temple 2.

The impact-resistant eyeglasses A of the present invention have attachment through-holes 21 formed in the temples 2, and cushion pads 1 are removably fitted into the attachment through-holes 21, so that if an impact is applied to the side of the face through the temples 2, the impact is mitigated. The eyeglasses are particularly suitable for use in sports eyeglasses, but can be applied to a variety of eyeglasses as long as this principle is utilized.
