Description

The present invention relates to an eyeglass frame or an eyeglass frame-type body posture corrector, and more specifically, the present invention relates to an eyeglass frame or an eyeglass frame-type body posture corrector. The present invention relates to an eyeglass frame or an eyeglass frame-type body posture corrector that prevents unconscious forward tilting of the head by inducing sexual reflexes, thereby correcting distortions in body posture such as hunched back.

FIG. 1 is a schematic diagram of facial muscles. Typical eyeglasses support the weight of the frames and lenses by having the modern parts rest on the shells of both ears, and the nose pads provided at the bridge part coming into contact with both sides of the root of the wearer's nose. In recent years, glasses have mainly been made of plastic lenses, which has reduced the weight of the glasses as a whole. becomes an unconscious tendency to look down, that is, to look down. In addition, since the nose pads straddle the root of the nose and come into contact with both sides of the bridge of the nose, they press on the subcutaneous eyebrow depressor muscle and levator labii nasalis superioris muscle in that area, causing a somatic reflex in these muscles. Shrink it.

A somatic reflex is a reflex reaction in which muscles contract involuntarily in response to a stimulus. The depressor of the eyebrows is a muscle that pulls the eyebrows down to create horizontal wrinkles at the base of the eyes, and the levator labii nasolini muscle is a muscle that lifts the upper lip and wings of the nose. The state in which the body contracts due to the somatic reflex caused by stimulation promotes the above-mentioned involuntary lowering of the head. Also, depending on the shape of the glasses, the lower edge of the rim that supports the lenses may come into contact with the lower part of the eye socket (upper cheek), causing a similar somatic reflex on the lower part of the subcutaneous orbicularis oculi muscle and the levator labii superioris muscle. causes contraction due to Since the modern part of the glasses is fixed by hanging over the ear shell, the whole glasses are pulled downward by the weight of the rims and lenses, as well as muscle contraction caused by somatic reflexes, which further increases the tendency for the head to descend. It turns out.

When the head is lowered, the cervical vertebrae, which normally draw an S-shape, bend forward, resulting in a so-called straight neck condition, the spine becomes hunched, and the pelvis tilts backwards. The reason why many people who regularly wear glasses tend to have a hunchback can be said to be largely due to the somatic reflex induced by the structure of such glasses. Such distortions in body posture not only cause stiff shoulders and necks, lower back pain, etc., but also lead to various diseases due to pressure on internal organs and poor blood circulation. In addition, a posture in which the heavy head is depressed and the chin is jutted out causes a lack of balance in the body, which can lead to falls.

In order to improve posture distortion caused by wearing glasses, it is preferable to remove the nose pads from the glasses to eliminate interference with both sides of the bridge of the nose. It becomes stable.

As prior art glasses without nose pads, those shown in Patent Documents 1 and 2 have been proposed and commercially available, but these prevent marks from the nose pads from forming on the skin on both sides of the bridge of the nose. It was invented primarily for cosmetic purposes. These prior technologies have a configuration in which a side pad is provided on the modern part instead of a nose pad to support the weight of the glasses on the side of the face. The zygomaticus major muscle is responsible for lifting the body, and the temporalis muscle, which is a masticatory muscle, is located under the skin of the temple. These muscles move actively when changing facial expressions, speaking, or eating, so this movement is transmitted to the eyelids, causing the glasses to move erratically. You will feel pressure in your temples. Further, by eliminating the nose pad, it is possible to eliminate pressure on the depressor eyebrow muscle and the levator nasalis superioris muscle, but it cannot be expected to have the effect of actively suppressing forward tilting of the head.
Japanese Patent Application Publication No. 2012-137577 Japanese Patent Application Publication No. 2016-206388

The present invention provides an eyeglass frame that eliminates the use of nose pads, actively prevents forward tilting of the head by utilizing somatic reflexes of facial muscles, and prevents distortion of body posture when wearing eyeglasses. Another object of the present invention is to provide an eyeglass frame-type body posture corrector that can be used by people who do not wear glasses to correct their posture.

In order to solve the above problem, the eyeglass frame according to claim 1 of the present invention has a bridge portion of a half-rim type eyeglass frame that does not have a nose pad . It is characterized in that it is provided with a support having one protrusion whose tip abuts on one point of the deepest part on the center line , and is supported by the root of the nose only by the one protrusion .

The eyeglass frame according to claim 2 is the eyeglass frame according to claim 1, in which the protrusion is in contact with one point of the deepest part on the center line of the root of the wearer's nose when worn, and is horizontal. It is characterized by pressing backwards .

Further, the eyeglass frame according to claim 3 is the eyeglass frame according to claim 1 or 2, and is characterized in that the upper ends of the left and right rim portions are in contact with the upper parts of both eye sockets when worn. do.

Further, the nose pad replacement part for eyeglass frames according to claim 4 is detachable by being hooked onto the front of the bridge portion of a half-rim type eyeglass frame without a nose pad, the bridge portion of which is located above the inside of the pair of lenses. The nose pad replacement part is an attachable nose pad replacement part, and the nose pad replacement part has a main body that is approximately Y-shaped when viewed from the front, and both upper ends of the main body are extended rearward and bent downward to form a center part of the bridge part. It consists of a pair of hooks for hanging on both sides, a support body formed by bending the lower end of the main body backward, and a protrusion provided at the tip of the support body, and the pair of hooks are connected to the eyeglass frame. When hooked and fixed on both sides of the center of the bridge part, only the tips of the protrusions abut the deepest point on the center line of the nose root of the wearer of the eyeglass frame and press horizontally backward, The eyeglass frame is characterized in that it is configured to be supported by the base of the nose.

The protrusion provided on the support body has its tip abutted against one point of the deepest part on the center line of the root of the nose so as to press it horizontally backward , and supports the eyeglass frame in place of the nose pad. There is a nasal root muscle under the skin of the root of the nose, and when it contracts, it pulls down the skin between the eyebrows and creates vertical wrinkles between the eyebrows, but when it comes into contact with light pressure like the weight of the rim or lens, the nasal root muscle itself No active contraction occurs. However, when the tip of the projection contacts the nasal root at one point, a reflex is evoked in the superficial sensory receptors in the skin above the nasal root.

Superficial sensory receptors are mechanoreceptors that feel the sensation of light touch on the surface of the skin of vertebrates, and are abundant in the skin of highly sensitive areas such as fingertips and the face. Reflexes caused by stimulation of superficial sensory receptors act in the direction of unconsciously trying to escape from the stimulation. For example, when a toe unconsciously flexes to escape the stimulation of a grain of sand that has entered a shoe, this is one of the reflexes caused by such superficial sensory receptors. Stimulation from the tip of the protrusion causes the superficial sensory receptors in the skin above the nasal root to produce a reflex in the direction of escaping from the protrusion, causing the skull to unconsciously move backwards and preventing the head from tilting forward. It will be done.

Further, in order to generate a reflex action that moves the skull backward, it is desirable that the protrusion abuts the root of the nose in a horizontal direction. Further, it is desirable that the protrusion makes contact with the root of the nose as lightly as possible, and that the contact is made at a "point" rather than over a wide area. If the contact is too heavy, the nasal root muscle itself will contract, and if the contact is made over a wide area, it will cause a reflex to reach the lower part of the nasal root and the skin on the sides. This is because it becomes subdued.

Furthermore, by configuring the frame body so that the upper ends of the left and right rim portions contact above the eye sockets when worn, the eyebrows are prevented from lowering. If you lower your eyebrows with the upper part of the rim in contact with the bottom of your eyebrows, pressure will be applied to the root of your nose through the projections, making you aware of the lowering of your eyebrows. This is because the reflex action of the sensory receptors is triggered, causing the skull to move backwards unconsciously, and the depression of the eyebrows is alleviated. The state in which the eyebrows lower and move inwards is mainly a state of expression of anger, and the reflex action of the superficial sensory receptors in the skin above the root of the nose urges the eyebrows to move away from each other to the left and right. Conversely, it can also be expected to be effective in stabilizing emotions.

Note that the eyeglass frame according to the present invention can naturally be used as eyeglasses by attaching lenses, but even when used without lenses, the above-mentioned posture correcting effect can be expected. Therefore, even people who do not wear glasses can use it to maintain and correct an appropriate posture that does not actively tilt the head forward by wearing only the frame body as an eyeglass frame body posture corrector on a daily basis. .

The eyeglass frame or eyeglass frame type body posture corrector according to the present invention has the following effects.
(1) Since there is no nose pad, it is difficult for the head to tilt forward due to the somatic reflex to the depressor eyebrow muscle and the levator labii superioris nasalis muscle, and distortions in body posture such as hunching are prevented.
(2) The forward tilting of the head is actively prevented by the reflex action of superficial sensory receptors triggered by point stimulation of the nasal root of the protrusion.
(3) By bringing the upper end of the rim into contact with the upper part of both eye sockets, lowering of the eyebrows can be suppressed and forward tilting of the head can be actively prevented.
(4) Since it can be used as an eyeglass frame type body posture corrector without wearing lenses, even people who do not wear glasses can actively maintain and correct their body posture.

(First embodiment)
Hereinafter, a first embodiment of the present invention will be described using the drawings. 2 to 6 represent an embodiment of the eyeglass frame according to the present invention, in which FIG. 2 is a side view, FIG. 3 is a top view, FIG. 4 is a front view, FIG. 5 is a back view, and FIG. It is a schematic diagram seen from the side with the frame being worn. The eyeglass frame 1 consists of a rim part 11 and a modern part 12. The rim part 11 extends left and right from the bridge part 10 and is connected to the modern part 14, but is a half rim that contacts only the upper edge of the lens to be attached. It is shaped like a mold.

The eyeglass frame 1 is not provided with a nose pad that common eyeglasses have, but is provided with a support 13 extending downward from a bridge portion 10, and a protrusion 14 at the tip of the support 13. As shown in FIG. 6, when the user wears the eyeglass frame 1, the protrusion 14 is configured to come into contact with the nasal root muscle on the center line of the nose root and support the eyeglass frame instead of the nose pad. ing. Since the support body 13 extends obliquely from the bridge part 10 toward the face side, the weight of the front side of the eyeglass frame 1 presses the root of the nose horizontally backward through the tip of the protrusion 14. Work as you would. When the tip of the protrusion 14 touches the base of the nose at one point, it causes a reflex in the superficial sensory receptors on the skin above the base of the nose, causing a reflex action in the direction of escaping from the protrusion, causing the skull to unconsciously move backwards. This prevents the head from tilting forward.

Of the structure of the eyeglass frame 1, the modern part 12 may be the same as that for general eyeglasses, and the bridge part 10 and the rim part 11 may have a shape and material that allow lenses to be appropriately mounted. The support body 13 is configured to have a length and angle such that the tip of the protrusion 14 comes into contact with a position slightly above the tip of the nasal root bone of the user. Further, the protrusion 14 is configured to contact the skin at the base of the nose at a point, but even though it is a point, it does not easily slide from the bridge of the nose to the left or right due to movement of the user's face or expansion and contraction of the skin. The tip shall be rounded so that it comes into contact with the skin over a certain area.

Further, it is preferable that the tips of the protrusions 14 are made of a soft material such as silicone rubber to prevent them from slipping, so that the protrusions 14 do not injure the face when the eyeglass frame 1 receives an external impact. Note that the support body 13 including the protrusion 14 may be integrally molded from silicone rubber or the like and attached to the bridge portion 10, or conversely, the bridge portion 10, the rim portion 11, and the support body 13 may be integrally formed from a hard material such as plastic. It is also possible to mold the protrusion 14 and cover the protrusion 14 with silicone rubber or the like.

Further, the rim portion 11 is configured such that the upper ends of the left and right sides contact the upper portions of both eye sockets when worn. With this configuration, when the eyebrows are lowered with the upper part of the rim part 11 in contact with the lower part of the eyebrows, pressure is applied to the root of the nose via the projections 14. As a result, the eyebrow depression becomes conscious, and the reflex action of the superficial sensory receptors in the skin above the root of the nose is triggered, causing the skull to unconsciously move backwards and the eyebrow depression to be alleviated.

Note that the eyeglass frame 1 according to the first embodiment is intended to be used as eyeglasses by attaching lenses as shown in FIGS. 4 and 5. In that case, a nylon thread for fixing the outer circumference of the lower edge of the lens may be provided on the rim portion 11, as in a general half-rim type eyeglass frame. However, it is not always necessary to wear lenses, and in the case of a person who does not wear glasses, the glasses frame 1 alone can be worn as a body posture corrector.

(Second embodiment)
7 to 11 are views showing a separate part 2 for reusing an existing eyeglass frame and making it usable as the eyeglass frame according to the present invention, FIG. 7 being a front view thereof, and FIG. 8 being a rear view thereof. , FIG. 9 is a plan view, FIG. 10 is a bottom view, and FIG. 11 is a right side view. Moreover, FIG. 12 is a front view of the existing eyeglasses F (the modern part is omitted) with the part 2 attached, and FIG. 13 is a rear view of the same.

Part 2 is integrally molded from a soft material such as silicone rubber, and has a support 21 by extending the lower part of a main body 20 having a pair of hooks 23 downward, and a protrusion 22 at the tip thereof. . The shapes of the support body 21 and the protrusion 22 correspond to the support body 13 and the protrusion 14 of the eyeglass frame 1 according to the first embodiment, respectively.

As shown in FIGS. 12 and 13, the part 2 is attached to the existing eyeglass frame F by hooking the hooks 23 onto the left and right rims from the front of the bridge portion. Note that the nose pad and the mounting fittings are removed from the eyeglass frame F in advance. The structure and effect in which the protrusion 14 of the support body 13 extending downward from the attached part 2 comes into contact with the root of the user's nose are the same as in the first embodiment.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not necessarily limited to the above-described configuration, and may be modified as appropriate within the scope of achieving the purpose of the present invention and having effects. As long as modifications can be made and fall within the scope of the technical idea of the present invention, they fall within the technical scope of the present invention.

The eyeglass frame according to the present invention can be used as eyeglasses by attaching lenses, and can also be used by people who do not wear eyeglasses as an eyeglass frame-type body posture corrector without attaching lenses.
