Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention reduces the load on the front part of the glasses that general glasses have by using a pair of cylinders and a string and utilizing the law of leverage, and furthermore, based on the string, The present invention relates to an eyeglass pulling holder for obtaining a holding force on the glasses.

[0002]

2. Description of the Related Art Conventionally, as a technique for obtaining a reducing force on glasses using lever's law, a weight is fixedly attached to the rear ends of left and right temples to reduce the load on the front of the glasses. There are types of glasses. (For example, Tokio A Hei 1
-136114).

[0003] Another technique for obtaining the holding power of glasses is to attach one end of a "stretchable string" or "mere string" to the rear ends of the left and right temples, and attach the other end to the back of the head. There is a sports band for eyeglasses of a type that enhances holding power by turning and binding to increase or decrease the length of the string.

[0004]

The glasses of the above-mentioned conventional type, in which the weight is fixedly attached to the rear end of the temple, certainly have the effect of reducing the load on the front part of the glasses according to Lever's law. . However, since it does not have an adjustment function for the reducing force itself, a weight is attached to the rear end of the temple to reduce the load on the front part of the glasses. As a result, the load of this weight is applied to the upper end of the base of the ear. The problem of growing is not solved.

[0005] Further, with respect to the "holding property to the glasses", since the weight of the weight is applied to the upper end of the base of the ear in the rear part of the glasses, the holding property is enhanced. However, there is a problem that the above-described holding performance is lower in the front part of the glasses than in the general glasses because the load on the front part of the glasses is reduced according to Lever's law.

On the other hand, a sports band has a sufficient holding ability for glasses. However, when wearing a “stretchy string” or “mere string”, the “moment in the downward direction due to the load on the front of the glasses”, which has existed conventionally, is still applied to both sides of the nose streak. Thus, the problem of reducing the eyeglasses has not been solved. An object of the present invention is to solve and provide the above problems.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention utilizes lever's law to counteract and respond to a downward moment existing at the front of the glasses. A pair of cylinders and a string are used.
By using these members, the action of leverage is generated, so that the load on the front of the glasses can be reduced, and the entire glasses can be held.

Hereinafter, the configuration will be described with reference to FIG. 1. (A) The left and right cylinders 1 are provided with a direction support portion 7 at the lower end as an extension of the side body, and form a right angle with the direction support portion 7. Cylinder 1
An angle supporter 3 is provided on the rear side surface of the camera. (B) Each of the left and right string portions 2 has a stopper portion 4 integrated with the string portion 2 at the lower end thereof, a ring portion 5 above the stopper portion 4, and a spherical convex portion 6 further above with an interval. (C) The upper end of the string portion 2 is inserted upward from below the hole of the tube 1 so that the stopper portion 4 and the ring portion 5 are left outside the lower end of the tube 1.

[0010] The term "lock" in claim 1 (a) is used to mean "put two or more combinable objects upright as they are combined".

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a contraction force generated between a ring portion provided in the middle of a string inserted through a tube and a spherical convex portion, and a friction force generated between a cylindrical hole surface and a spherical convex portion. Based on both effects, a pair of left and right cylinders on the temple of glasses,
Due to the string at the upper end of the tube, when pulled backward with respect to the front of the glasses, the stopper provided at the lower end of the string becomes a fulcrum in the law of leverage, and an upward moment is applied to the front of the glasses. Therefore, while maintaining that state, the straps from the left and right are bound and hung at the back of the head. In the above case, the angle support portion secures the engagement angle of the tube in the temple, and functions as an auxiliary portion for the tube to perform a stable function as “lever” in the law of lever.

The directional support provided at the lower end of the tube is such that the bottom surface of the angle support attached to the tube is the temple when the tube rotates in parallel to the horizontal plane on the temple when the present invention is worn. In order not to deviate from above, the left and right ends of the directional support portion interfere with the side surfaces of the temple to prevent the rotation, and serve to secure the directionality of the cylinder.

Further, when the inner diameter of the cylinder is formed so as to be tapered from the lower side to the upper side, in the case of a cylinder having a limited length, the inner diameter of the cylinder becomes larger between the spherical convex portion and the cylindrical hole surface. It works to obtain an effective pressure state.

[0013] If the tube is worn in a manner that it is engaged with the middle part of the left and right temples, it acts so as to pinch the right and left temporal regions together with the strings, and thus has a temporary reduction effect on the front of the glasses. However, a preferable anchoring position of the cylinder for producing the above-mentioned lightening effect is a position where the stopper works most effectively as a fulcrum in Lever's law, that is, a front portion of the base of the ear.

FIG. 8 shows the relationship between the cylinder, the ring, and the spherical projection.
First, the loop provided in the middle of the string 2 inserted into the tube binds the temples of the glasses at the lower end of the tube, while the spherical projection has an outer diameter of Since it is provided slightly larger than the inner diameter of the cylinder, a strong pressure relationship within the cylinder hole and corresponding to the surface of the cylinder hole is maintained.

In this state, when the string at the upper end of the cylinder is strongly pulled upward, the loop more securely binds the temple, and the spherical convex portion has a strong frictional force generated between the temple and the hole of the cylinder. It moves upward in the cylindrical hole with close contact, and at the same time, the string between the ring and the spherical projection has the "stretch" of this string.
A strong contraction force as a reaction to

As described above, these forces act organically,
The cylinder which is in contact with the spherical convex part at the upper part in the cylindrical hole with the pressure corresponding to each other can be engaged on the temple.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, a cylinder 1 in FIG. 1 as a main embodiment has an angle support portion 3 adhered to the rear side surface or by a two-color molding method. Regarding the length and outer diameter of the cylinder 1, it is preferable that the lever's law can be effectively used, and that it is within a range that does not cause discomfort at the temporal region.

The thickness of the side wall of the cylinder 1
It is necessary that the wall thickness be large enough to withstand the contracting force generated by the string 2 between the ring portion 5 and the spherical convex portion 6 in the hole and the force pulled backward by the string 2.

The cylinder 1 is formed by cutting a commercially available pipe having the same inner diameter from the bottom to the top as shown in FIGS. 2 and 4, or as shown in FIG. 5 as a main embodiment. In addition, it is desirable that the inner diameter of the hole is formed in a tapered shape so that the inner diameter becomes smaller as going upward from below.

The angle of the cylinder 1 on the temple is
It may be perpendicular to the temple, or may be tilted backward as long as leverage is effectively obtained.

As for the members of the cylinder 1, synthetic rubber having elasticity, adhesion and bending resistance, for example, urethane TP
E is preferred.

In FIGS. 1 and 7, the string 2 preferably has a circular cross section, and its outer diameter is larger than the inner diameter of the cylinder 1 in consideration of the outer diameter of the spherical projection 6. Must also be small. The material of the string 2 is preferably a synthetic rubber having elasticity, adhesion, and elasticity, for example, a urethane-based TPE molding material similar to a cylinder.

As shown in FIGS. 4, 5 and 6, the angle support portion 3 provided on the rear side surface of the cylinder 1 has a shape in which the cone is vertically halved in order to make close contact with the side surface of the cylinder 1. After the surface is formed in a tapered shape and formed by integral molding, the above-mentioned vertical surface is attached to the rear side surface of the cylinder 1 by adhesion or provided together with the cylinder 1 by a two-color molding method. At this time, it should be noted that the bottom surface of the angle support portion 3 and the bottom surface of the cylinder 1 are flush with each other. As for the member, the same synthetic rubber as that of the cylinder 1, for example, urethane-based TPE is suitable.

As shown in FIG. 7, the stopper portion 4 is integral with the string 2 and has a rod-like shape curved backward along the front portion of the base of the ear. Its length is
As long as the stopper portion 4 can effectively act as a fulcrum in the leverage rule, the length may be within a range that does not cause discomfort when worn according to the present invention. Shape. In that case,
It is necessary to consider the matching of the directionality with the limb 5.

As shown in FIG. 7, the loop portion 5 is integral with the string 2 and extends through a notch long enough to allow the temple 9 of general glasses to pass therethrough in the longitudinal direction of the corresponding portion of the string 2. Put and form. In the formation, it is necessary to pay attention to the matching of the directionality with the stopper portion 4 as described above.

As shown in FIG. 7, the spherical convex portion 6 is integral with the string 2 and has a substantially bump-shaped spherical surface. For the formation, a notch shorter than the above-mentioned ring portion 5 is cut into the corresponding portion of the string 2 until it penetrates in the vertical direction, and a plastic piece is sandwiched in the gap and bonded. The thickness of the plastic piece must be such that when the spherical convex portion 6 is positioned in the cylinder 1 and acts, sufficient frictional force and adhesion can be obtained between the plastic piece and the hole surface of the cylinder 1. It is.

As shown in FIGS. 1, 2, 3, and 4, a directional support portion 7 as a main embodiment is integral with a cylinder 1 and has a shape of a shoe horn that is formed by cutting the lower end of the cylinder 1 in half vertically. Form a semi-cylindrical shape. For the formation, there are the following methods. (A) In the case where a commercially available molded pipe is used as the cylinder 1, this pipe is cut, and one end is formed into the shape described above. (B) It is provided in the shape described above by integral molding. In addition, the width of the direction support portion 7 is formed while taking into consideration that the side surface of the temple 9 and the left and right ends of the direction support portion 7 can effectively interfere with each other. Care must be taken to leave, on the temple 9 of the glasses, a space on the bottom surface of the tube where the tube 1 can stably engage.

As described above, as shown in FIG.
There is also a method in which the inner diameter is formed in such a manner that the inner diameter is tapered toward the upper side. At the time of its formation, the cylinder 1
Note the relationship between the inner diameter of the spherical projection 6 and the outer diameter of the spherical projection 6. Since the inner diameter is too narrow, the spherical projection 6 is blocked from going up in the cylinder 1 and moves upward. It is necessary to take care not to be unable to do it. The cylinder 1 is formed by integral molding.

Further, the use of the present invention will be described with reference to FIG. 9. (A) The temple 9 is passed through the left and right loops 5 and the cylinder 1 is placed at the position where the stopper 4 is hooked at the front of the base of the ear. With one hand, pull strongly on the string 2 at the upper end of the cylinder 1
To the temple 9. (B) When the above-mentioned string 2 is gradually pulled backward from the temporal region, the front part of the glasses is gradually lightened as the "working point" by the action of the lever and rises. Then, the string 2a is turned around the back of the head and bound. (C) Further, in order to more reliably obtain the holding force of the entire glasses, the cylinder 1 is moved from the hinge 10 at the tip of the temple 9.
When the length of the temple 9 to the anchor position is shortened, the distance between the front part of the glasses and both sides of the nose streak is reduced, so that the holding force can be increased. (D) Further, in order to reduce the burden of applying the load of the glasses on both sides of the nose streak, in reverse to the operation of (c), the engagement position of the cylinder 1 from the hinge 10 at the tip of the temple 9 is reversed. When the length is large, the distance between the pair of "nose pads" in the center of the lens frame of general glasses and the nose becomes longer, and "clearance" is generated by that much. The load applied to both sides of the nose can be reduced. (E) By selectively performing the above operations (c) and (d) and performing the operations in detail, it is possible to relatively adjust the force for reducing the load on the front portion of the glasses and the holding force for the glasses.

As another embodiment (a), the string 2 will be described.
As shown in FIG. 10, the string 2 tied around the back of the head
The string 2a may be a separate string 2a separate from the string 2 inserted through the string. In the main embodiment of the present invention, as shown in FIG.
The string 2 and the string 2a are treated as "integral string".

As another embodiment (b), as for the shape of the string 2a, besides forming a circular cross section, as shown in FIG. May be provided at the left and right ends of the string 2a.

As another embodiment (c), FIG.
As shown in FIG. 2, a method is also conceivable in which the string 2a bound at the back of the head is bound and stopped by the binding pipe 8.

The above-mentioned other embodiments (b) and (c) can be similarly carried out in the case of the string 2 in the main embodiment. In addition to these methods, any method can be used as long as the cord 2 can be hung at the occipital region.

[0034]

The present invention is implemented as described above, and has the following effects.

First, by utilizing Lever's law,
Since it has a function of reducing the load on the front of the glasses, it is possible to prevent so-called "glass marks" from remaining on both sides of the nose streak and to prevent pain, and it is possible to wear glasses for a longer time than before.

Since the right and left straps 2 or 2a are wrapped around the back of the head from the side of the head and held so as to surround the rear half of the head, the glasses slip or drop even during exercise. Can be prevented.

Further, the cylinder 1 can be moved in the front-back direction on the temple 9 by the action of the ring portion 5, so that the engagement position of the cylinder 1 can be arbitrarily changed. And the holding force on the glasses can be relatively adjusted.

Further, as shown in the embodiment, one string portion 2
Is provided with a stopper portion 4, a ring portion 5, and a spherical convex portion 6, and has three functions as their functions, so that the present invention can be reduced in size and weight.

As described in the embodiment, when the cylinder 1 on the temple 9 is rotated in parallel with the horizontal plane, the left and right ends of the direction support portion 7 interfere with the side surfaces of the temple 9. Then, since the above operation is suppressed, the angle support portion 3
Is prevented from falling off the temple 9 and
Direction can be secured.

Further, as in the embodiment, the inner diameter of the cylinder 1 is gradually reduced from the lower side to the upper side, so that the frictional force and the adhesion between the hole surface of the cylinder 1 and the spherical projection 6 are increased. As the force increases accordingly, cylinder 1
It is possible to more reliably hang on the temple 9.
