Abstract

PROBLEM TO BE SOLVED: To provide spectacles A without a nose pad that do not charge a load on the nose part, have a certain supporting force, and provide stable wearing property when they are worn.SOLUTION: The spectacles A without a nose pad of the present invention include a front part 3 and temple bodies 2 attached to the front part 3. An auxiliary temple piece 1 is detachably attached to each temple body 2. The auxiliary temple pieces 1 are supported by the cheek bones and occipital region. The temple bodies 2 are supported by the ear parts and the occipital region.

Description

  The present invention relates to spectacles having no nose pads, and more particularly to spectacles having no nose pads that are securely supported without any load on the nose and have excellent mounting stability.

General eyeglasses are provided with a nose pad to support the weight of the lens on a bridge (so-called “mountain”) in the front part or a rim near the bridge.
The nose pad is supported by the wearer's nose, and the rear end portion (modern portion) of the temple is supported by the ear portion so that the glasses are attached to the face.
However, since the weight of the front half of the glasses acts to press the nasal bone through the nose pad, a large burden is applied to the nose.
In particular, when the lens is heavy like thick glass, the contact pressure increases and the burden on the nasal bone increases.

Further, since the nose pad portion is in contact with the skin, the pressed portion may turn red or may be extremely rubbed and scratched.
In particular, since women apply makeup, it is necessary to avoid as much as possible that the load concentrates on a part of the nose and that only the part can be removed.
In order to solve such a problem, some glasses having no nose pads without a nose pad have been developed.

  For example, Patent Literature 1 and Patent Literature 2 show glasses that are not provided with a nose pad, and have a structure in which these slip-off prevention portions or slip stoppers are provided in the middle position of the temple. The position can be adjusted.

Patent Document 3 discloses spectacles having no nose pads provided with a contact portion such as a curved leaf spring that presses the temple portion, and one end of the spring plate is slidable for adjusting the shape. ing.
However, both of these are supported only at two places, the cheekbone and the ear part. For example, when the glasses are heavy, the force to push down the front part relatively forward is inevitably increased.
As a result, there arises a problem that the rim is lowered until it contacts the nose.
Further, since there is no nose pad, the supporting force is insufficient, and it is easy to come off when exercising, and so-called stable wearing property is lacking.

Further, Patent Document 4 shows spectacles that do not have a nose pad. This is because the locking member provided on the temple includes an extension member and an ear pad member, and the spectacle frame is formed by the extension member. Is not pulled excessively rearward, and the spectacle frame is prevented from shifting forward by the ear resting member.
This prevents the shift by the function of the locking member at the position of the ear, so it is impossible to reliably stabilize the mounting property.

  As long as the object of the present invention is met, a configuration in which the inventions of (1) to (10) are appropriately combined can also be adopted.

The nose pad-less spectacles of the present invention is a nose pad-less spectacles provided with a front part and a temple body part attached to the front part, and an auxiliary temple piece is attached to the temple body part. Since the auxiliary temple piece is supported by the cheekbone, the occipital region, and the ear part, the temple body and the auxiliary temple piece are supported by the cheekbone, the occipital region, and the ear part in cooperation with each other. Provides stable wearability.
Further, the auxiliary temple piece 1 can be prepared separately from the eyeglass body, and the auxiliary temple piece 1 can be assembled on site.

The auxiliary temple piece is supported by the cheekbone and the back of the head, and the temple main body is supported by the ear and the back of the head, so that the glasses themselves are attached to the cheekbone by the cheekbone support portion 11 of the auxiliary temple piece 1. In addition, since the back head is supported by the back head support portion 12 and further by the temple main body portion 2 by the ear portion and the back head portion, the pressure burden on each supported portion is reduced. Moreover, since the head is supported at four points, the holdability is extremely good.
The auxiliary temple piece is substantially L-shaped, and includes a occipital region support portion and a zygomatic support portion that extends downward from the front end portion of the occipital region support portion, and the temple body portion is attached to the zygomatic support portion. Therefore, the zygomatic support portion extending downward is efficiently supported by the cheekbone and the occipital support portion is efficiently supported by the occipital region.
Since the position of the auxiliary temple piece can be adjusted by moving along the temple main body, it can be set to an optimum position for the head shape of each individual.
Since the auxiliary temple piece is detachably attached, even if it is attached once during adjustment, it can be removed again as necessary.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings as necessary.
In the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted. Further, the dimensional ratios in the drawings are not limited to the illustrated ratios.

(First embodiment)
FIG. 1 is a perspective view showing nose pad-less spectacles A according to the first embodiment, and FIG. 2 is a plan view showing nose pad-less spectacles A according to the first embodiment.
FIG. 3 is a side view showing the nose pad-less spectacles A according to the first embodiment.

As shown in FIG. 1, the nose padless spectacles A according to the first embodiment includes a front part 3 having a lens 31, a bridge 32, and the like, a temple main body 2 attached to the front part 3, and the temple main body. The part 2 includes an auxiliary temple piece 1.
In addition, although the balancer W was shown with the chain line in FIG. 3, this is mentioned later.

The present invention is characterized in that the auxiliary temple piece 1 is provided.
In this embodiment, the temple body 2 is fixed with respect to the front portion 3 and can be freely opened and closed. However, there is no pivoting portion (so-called hinge), and the temple body 2 is rotated by elastic bending of the temple body 2. Dynamic opening and closing is performed.
When worn on the face, there is almost no burden on the nose, and the entire spectacles are securely supported (that is, held) by the head, so that the wearing stability is excellent and the fit is very good.
The auxiliary temple piece 1 is attached at a substantially intermediate position of the temple main body 2 and can be easily attached.

FIG. 4 shows the auxiliary temple piece 1, (A) is a side view, and (B) is a plan view.
And (C) shows the cross section of the cheekbone support part 11.
The auxiliary temple piece 1 is formed in a substantially L shape, and includes a occipital head support portion 12 and a zygomatic support portion 11 extending downward from a front end portion of the occipital head support portion 12.
Further, the auxiliary temple piece 1 is appropriately curved inward in a plan view, and holds the head accurately.

The zygomatic support portion 11 of the auxiliary temple piece 1 is supported by abutting the cheekbone (specifically, zygomatic arch) of the head, and the other occipital region supporting portion 12 is abutted by the upper occipital region.
Two attachment holes P are provided on the side surface of the auxiliary temple piece 1 so as to cross.
As can be seen from the cross-sectional view, the mounting hole P is formed so that the opening of the mounting hole P is narrow. Therefore, as will be described later, the mounting can be easily performed so as not to be detached from the temple body 2.

Here, various materials can be used as the material of the auxiliary temple piece 1, but a synthetic resin is preferable from the viewpoint of fit to the head and lightness.
In the cheekbone, since the auxiliary temple piece 1 is in direct contact with the facial skin, a synthetic resin (for example, polyamide resin such as nylon, acetate resin) is suitable from the viewpoint of touch and warmth.

On the other hand, the temple body part 2 is supported by a part of the back of the ear hook part (also called a modern part) that is hooked on the ear and the other part is in contact with the lower back of the head. Supported by dots.
As described above, the nose pad-less spectacles A of the present invention are supported on the cheekbone of the head, the upper occipital region, the lower occipital region, and the ear portion by the temple body 2 and the auxiliary temple piece 1 when worn. The load is distributed.
Therefore, the pressure burden on the head is extremely lighter than that of conventional glasses with no nose pads.
Moreover, since the temple body 2 is supported at a total of four locations, two at the temple main body 2 and two at the auxiliary temple piece 1, the eyeglass wearing position is stable and the holding property is excellent, and for example, it can withstand intense exercise.

By the way, since the auxiliary temple piece 1 can be moved along the temple body 2 after being attached, the position of the auxiliary temple piece 1 relative to the temple body 2 can be adjusted.
Therefore, when purchasing eyeglasses, it can be easily fitted to the face on the spot.
Specifically, taking into account the size, shape, cheekbone position, and the like of the customer's head, the auxiliary temple piece 1 is adjusted to the optimum position for the person.
And the auxiliary temple piece 1 and the temple main-body part 2 are hardened using the adhesive agent etc. in the position.
In this case, the attachment hole P may be filled with an adhesive.

As described above, the position of the auxiliary temple piece 1 can be adjusted by moving along the temple main body portion 2, but depending on the person, the cheekbone surface of the auxiliary temple piece 1 has an angle. 11 may hit one side.
Here, by configuring the temple main body 2 with the metal wire 21, the temple main body 2 is appropriately twisted, and accordingly, the zygomatic support 11 can be reliably brought into contact with the surface of the zygomatic portion.

Next, the principle of attaching the auxiliary temple piece 1 to the temple body 2 will be described.
Here, the temple body 2 is made of a metal wire 21 (as a material, for example, an elastic metal such as beta titanium or a superelastic metal), and is capable of at least some elastic torsional deformation.
The metal wire 21 is preferably a crushed wire, that is, a flat wire.

The auxiliary temple piece 1 is configured such that the metal wire 21 of the temple main body 2 is attached to the side surface thereof.
The side surface portion of the auxiliary temple piece 1 is provided with two long attachment holes P (that is, grooves for attachment) so as to cross the left and right, and the opening width L3 of the attachment hole P is the above-described width L3. The metal wire 21 is formed to be larger than the thickness L1 and smaller than its width L2 (see FIGS. 4 and 5).
Therefore, in order to attach the metal wire 21 which comprises the temple main-body part 1 to the attachment hole P, let the open | release opening pass in the state which twisted the metal wire 21 a little.
Thereafter, by returning the twist, the metal wire 21 is securely attached to the attachment hole P and does not leave.

Thus, since the metal wire 21 which comprises the temple main-body part 2 can be easily attached to the auxiliary temple piece 1, the auxiliary temple piece 1 is prepared separately from the spectacles main body, and the auxiliary temple piece 1 is assembled on the spot. be able to.
As described above, in the nose pad-less spectacles A of the present invention, when the auxiliary temple piece 1 is attached, the auxiliary temple piece 1 extends and spreads upward at a certain angle with respect to the temple body 2. It becomes and becomes bulky.
However, since it is sufficient to prepare them separately in this way, it is extremely efficient from the viewpoint of physical distribution and storage.

FIG. 5 is a view for explaining an attaching operation between the auxiliary temple piece 1 and the temple body 2 (specifically, the metal wire 21).
First, the metal wire 21 is made to face the opening.
And it is made vertical by twisting (A).
Next, the metal wire 21 is moved, passed through the opening, and inserted into the attachment hole P (B).
Since the thickness L1 of the metal wire 21 is narrower than the width L3 of the opening, it can pass without any trouble.
Then, after entering the mounting hole P, the twist is eliminated and the original horizontal state is restored (C).
Since the metal wire 21 is prevented from being opened at the opening by trying to move after that, the metal wire 21 is prevented from being released further.
Once the metal wire 21 enters the mounting hole P, the width L3 of the opening is narrower than the width L2 of the metal wire 21 and is blocked and cannot pass.

By the way, the auxiliary temple piece 1 is moved and positioned at a position suitable for the head.
In this state, the metal wire 21 is fixed to the attachment hole P using an adhesive.
When it is desired to remove the metal wire 21 before fixing, the metal wire 21 is twisted to be vertical, and is easily detached by passing through the opening.
Here, if the width L4 of the attachment hole P is made slightly smaller than the width L2 of the metal wire, the attached metal wire 21 is pressed against the inner wall of the attachment hole P so that the position does not shift.

  Alternatively, by keeping the interval between the metal wires 21 slightly larger than the interval between the two mounting holes P, resistance force is generated due to the repulsive effect of the two wires even when trying to slide, so that the position does not shift. Can do.

(Modification of mounting holes)
The attachment of the auxiliary temple piece 1 and the temple body (specifically, the metal wire 21) is not limited to the attachment hole P as described above.

FIG. 6 is a diagram for explaining another attachment state of the auxiliary temple piece 1 and the temple body 2 (specifically, the metal wire 21A).
As can be seen from the cross section, the mounting hole P1 is formed in an L shape in the depth direction (A).
By inserting the metal wire 21A (B) and sliding it slightly in the lateral direction, the metal wire 21A is mounted at a position where it does not leave (C).
In this state, the metal wire 21 is securely fixed to the attachment hole P1 using an adhesive or the like.
In this modification, the metal wire 21A does not need to be twisted, so that it can be applied to a round wire (circular cross section) instead of a flat wire as in the above-described embodiment.

FIG. 7 is a view for explaining still another attachment state between the auxiliary temple piece 1 and the temple main body (specifically, the metal wire 21A).
(A) is a side view of spectacles, (B) is sectional drawing of the cheekbone support part 11 in an auxiliary temple piece.

Unlike the case of FIG. 6, in the form in which the rear end portion of the temple main body 2 is open, an attachment hole P <b> 2 that penetrates the auxiliary temple piece 1 may be provided, and the rear end portion may be inserted into the attachment hole P <b> 2. Can be installed very easily.
In this state, similarly, the metal wire 21A is securely fixed to the attachment hole P2 using an adhesive or the like.
When the tip of the rear end portion 22 is dangerous, it is preferable to attach a cap S or the like after the auxiliary temple piece 1 is attached.

(Second Embodiment)
In the above-described embodiment, the example in which the nose pad-less spectacles A of the present invention have the temple body 2 directly attached to the lens without the front portion 3 having a rim has been shown.
However, the present invention is naturally applicable to the case where the front portion 3 includes a rim.
FIG. 8 shows spectacles A without a nose pad provided with a front part 3 with a rim.
The temple main body 2 is attached to the rim, which can also be opened and closed by elastic bending.

(Third embodiment)
In the above-described embodiment, the nose pad-less spectacles A have been shown in which the temple body 2 is opened and closed by its elastic bending, but the temple body 2 is opened and closed via a hinge 34 (so-called “hinge”). Even if it is a thing, it is employable.
FIG. 9 shows nose pad-less spectacles A in which the temple body is provided with a hinge 34.

(Fourth embodiment)
This embodiment is an example of nose pad-less glasses A in which the front portion 3 includes a rim and the temple body portion 2 includes a hinge 34 (FIG. 10).
The temple body 2 is fixed to the rim and opens and closes via a hinge 34.
Also in each embodiment mentioned above, by providing the auxiliary temple piece 1 in the temple main body portion 2, a load is not applied to the nose portion at the time of wearing, and the supporting force is reliable, and a stable wearing property is obtained.

(Fifth embodiment)
The embodiment of FIG. 11 is an example in which the shape of the auxiliary temple piece 1 is different from that described above.
This is a case where the temple body 2 is short, and the back head support portion 12 of the auxiliary temple piece 1 is bifurcated and is branched into an upper support portion 12A and a lower support portion 12B.
The upper support portion 12A is supported by the back of the head and the lower support portion 12B is supported by the ear portion.
By adopting such a bifurcated auxiliary temple piece 1, the parts supporting the back of the head are made of the same material, and a uniform appearance can be obtained.
In this example, an attachment hole P3 having a wide groove shape is provided in the cheekbone support portion 11, and the metal wire 21A is bent so as to be reduced inward and is fitted as it is.
In addition, it is preferable to form a narrow groove into which the metal wire 21A is further fitted in the attachment hole P3.

(Sixth embodiment)
FIG. 12 shows an embodiment in which the temple body 2 is not a wire but a plate-like body.
(A) is a side view, (B) is a view of the zygomatic support part viewed from the inside, and (C) is a cross section of the zygomatic support part.
The material of the plate-like body is a metal or a plastic material, but is not necessarily limited to this.
A slot P4 is formed in the auxiliary temple piece 1, and both are attached by press-fitting the temple body 2 into the slot P4.
A groove portion Q is formed inside the cheekbone support portion 11 of the auxiliary temple piece 1 and the groove portion Q bites into the skin.
The groove portion Q is preferably formed in the horizontal direction in order to prevent vertical displacement, but may be inclined to prevent forward / backward displacement.
Moreover, as the groove part Q, what is necessary is just the shape which bites into skin, and you may form multiple.

(Use of balancer)
By the way, the lens material, size, thickness, and the like differ depending on the person wearing the glasses.
That is, the weight of the lens is different for each person, and as a result, the position of the center of gravity of the glasses also changes.
On the other hand, in the case of a heavy spectacle frame in the front part, the center of gravity position related to the weight of the lens is biased to the front side.
When the position of the center of gravity is too biased toward the front side, the contact pressure on the cheekbones becomes strong.
Therefore, in order to change the position of the center of gravity to the optimum position, a balancer W is attached to the rear end as shown in FIG. 3 to adjust the contact pressure to the cheekbone.

(Applied to glasses other than spectacles A without nose pads)
As described above, the nose pad-less spectacles A according to the present invention has the advantage that the nose pad does not hit the wearer's nose because the auxiliary temple piece 1 is provided.
However, it is naturally possible to apply this principle to eyeglasses equipped with a nose pad.
That is, it is extremely useful in reducing the contact pressure of the nose pad to the nose.
For those who feel uncomfortable when wearing spectacles A having no nose pads, the burden on the nose can be greatly reduced by providing the auxiliary temple pieces 1 as in the present invention to the spectacles having nose pads. it can.

As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment.
In the nose pad-less spectacles A according to the present embodiment, the mounting hole P is not limited to the embodiment, and any modification is possible as long as it is removable.
Also, the number of metal wires constituting the temple body may be three or more, and there may be a portion where the bundle of metal wires 21 is partially shared.

The present invention is extremely excellent in mounting stability because there is almost no burden on the nose and it is reliably supported.
Therefore, the present invention can also be applied to a wide range of spectacles such as business spectacles used for welding or spectacles capable of viewing a location image.
