TECHNICAL FIELD OF THE INVENTION
According to the present invention, when the glasses are put on the face, the front part is supported by the nose through the nose pad, and the vine extending from the front part is hung on the ear, but the present invention engages with the depression inside the outer ear ring The present invention relates to a vine of a spectacle frame that can be used.
[0002]
[Prior art]
The glasses are composed of a front part and a crane attached to both sides of the front part, and the crane can be folded through a joint such as a hinge. There are various forms of the front portion. In general, both rims are connected by a connecting member, and a oyster is brazed to the outside of the rim. There is also a front part of a type that uses an upper half half rim as a rim and holds the lower part of the lens with a water thread. Further, edgeless glasses, in which both lenses are directly screwed to both sides of the connecting member without using a rim, and a yoloy is directly screwed to the outside of the lens, are often used.
[0003]
A nose pad is attached to each of the front parts and supported against the back of the nose, and the vine extending from both sides of the front part reaches the ear from the side of the face and is inserted into the tip of the vine. Modern is designed to be hooked to the ear. Thus, the glasses can be stably worn on the face by the front part and the vine.
[0004]
Various measures have been taken so that the glasses worn on the face do not shift, and of course, do not come off the face, and a soft silicone resin is used as the material of the nose pad that supports the front part against the back of the nose And it does not slip and makes the skin contact good. In addition, various measures have been taken such as providing a silicone resin layer inside the modern, or forming a fine uneven surface.
[0005]
By the way, in the case of reading glasses that are worn temporarily when reading newspapers or magazines, glasses with a compact front part are often preferred. This is because it is convenient to carry and there is little need to fit a large lens on the front part when reading newspapers and magazines temporarily. As described above, even if the size of the front part is reduced, the length of the crane extending from the front part so as to be locked to the ear cannot be shortened. It is impossible to reduce the size.
[0006]
Therefore, there is known a crane configuration in which the crane is shortened and a pad is attached to the tip, and the pad can engage with the depression of the outer ring of the ear. Therefore, when the vine is folded, the whole is very compact and portable. As glasses equipped with such a short vine, for example, a “glass vine” disclosed in Japanese Utility Model Laid-Open No. 4-50818 is known. The free end of the crane is formed with an engaging portion capable of engaging with the ear recess of the human body.
[0007]
However, the shape of the human ear varies widely, and even if the engaging portion is formed at the free tip of the crane, the engaging portion is difficult to engage with the depression (recess) in the outer ring of the ear. There are many. Forced engagement can cause pain and sometimes fall off. The gazette also describes a specific example in which the entire crane is formed of a spring, but the entire crane formed of a spring bends and deforms, and the engagement pressure when engaging with the depression is too small to allow the glasses to be worn. A feeling of fitting when worn is not obtained, and the glasses are easily detached.
[0008]
[Problems to be solved by the invention]
As described above, the conventional glasses frame having the short vine has the above-described problems. The problem to be solved by the present invention is this problem, in which a crane is shortened and an engaging portion that engages with a recess of the ear is provided at the tip, but pain may be caused by an ear of any shape. Provided is a crane of an eyeglass frame that is easily engaged and hung without feeling. Here, the target glasses are not limited to reading glasses, but also include general myopia glasses and sunglasses.
[0009]
[Means for solving the problem]
The crane of the eyeglass frame according to the present invention is provided with an engaging portion that can be fitted and engaged with the outer ring of the ear or the recess inside the outer ring without inserting a general L-shaped modern as in the related art. . In addition, the following features are provided so that the engaging portion can be fitted to any type of ear.
(1) The length of the vine is adjustable. However, the specific adjustment means is not limited, but there are various types of depressions inside the outer ring of the ear, and the length of the vine can be adjusted to engage the tip engagement portion with any depression. I have to.
[0010]
(2) The tip of the crane has a bent or curved arm, and an engaging portion such as a pad is attached to the tip. The arm portion is made of a material having excellent elastic deformation, and its direction can be freely changed. In other words, the crane body can be flexed and deformed, but is relatively rigid, and the bent or curved arm at the tip gives the arm an excellent elastic deformation property, so that the engaging portion fits into the recess of the ear and Moderate pressure is applied.
[0011]
(3) Although the form of the engaging portion is free, it can be attached to the tip to change its direction. Therefore, it can be fitted and engaged with the inner shape of the ear cavity.
(4) The outer circumference of the crane tip around the arm is sealed to prevent hair from getting caught when wearing glasses. Of course, there is no need for a seal if the tip is structured so that the hair does not get caught.
Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0012]
【Example】
FIG. 1 is a plan view showing an eyeglass frame provided with a crane according to the present invention. In the figure, reference numeral 1 denotes a rim on which a lens fits, 2 denotes a connecting member, 3 denotes a helmet, and 4 denotes a crane. Both rims 1 and 1 are brazed to both sides of the connecting member 2 and On the outside, the above yoroi 3 and 3 are fixed by brazing. The vines 4 and 4 are mounted so as to be foldable via joints 5 and 5 provided at the ends of the yoroi 3 and 3, respectively.
[0013]
By the way, the crane 4 fits into a groove formed in the base 6 and is fixed with a screw 7, and its length can be adjusted by sliding along the groove. Of course, there are various other length adjusting mechanisms for the crane 4 as described later, and the adjusting mechanism shown in FIG. 1 is merely one specific example. An engaging portion 8 made of resin is provided at the tip of the crane, and the engaging portion 8 fits into and engages with a concave recess inside the outer ring of the ear.
[0014]
The engaging portion 8 is formed by a smooth curved surface having a substantially egg-shaped shape, and is fitted in a concave portion of the ear so as not to be displaced or detached. Of course, the shape of the engaging portion 8 is not limited to the above-mentioned egg shape, but may be any shape as long as it can engage with the depression without pain. Here, although the material of the crane 4 is not limited, a conventional crane for a spectacle frame may be used. The crane 4 has elasticity that can be appropriately bent and deformed so that the engaging portion 8 does not feel pain even if it is fitted in the recess of the ear. I have. When a crane material having poor elasticity is used, a spring hinge is used as the joint. As is well known, the spring hinge is configured so that the crane 4 can be pushed outward from a state where the crane 4 is opened when wearing glasses, and the engaging portion 8 is pressed with an appropriate pressing force. It fits into and engages with the ear cavity.
[0015]
In the embodiment shown in FIG. 1, the crook tip bent portion 9 is not the same wire as the crane 4, but this crook tip bent portion 9 is formed of an elastic member such as a coil spring, so that it can be easily engaged with the recess of the ear, and the engaging force is reduced. The structure has a structure for relaxing and adjusting at the bent end portion 9. FIG. 2 shows an enlarged view of a portion A in FIG. Although there are various forms as described above, the pad 16 provided at the tip of the vine engages with the depression of the ear when wearing glasses, and has a form capable of fitting without pain.
[0016]
(A) has a length adjusting mechanism at the tip of the crane, and a screw 13 is screwed into a pipe nut 14. The arm 15 bent in a substantially L-shape is constituted by a coil spring, and a pad 16 is attached to a tip of the arm 15. Since the length of the crane 4 is adjustable, the pad 16 is adjusted so that the pad 16 engages with the ear cavity. In this state, the arm 15 can flex freely. For example, even if the pad position is slightly displaced, it is possible to cope with the bending deformation of the arm 15 without giving any pain to the depression of the ear. Here, the pad 16 may be made of a relatively soft resin, or may be covered with a cover on a dirty surface.
[0017]
(B) is a specific example in which the bending angle of the arm 15 with respect to the vine is different from that of (a), but is different.
(C) shows a case in which the outer peripheral surface of the tip end of the crane of (a) is sealed. When the eyeglasses are worn, the hair may be hooked on the coil spring because the coil spring is located near the ear. The tip is sealed to prevent such a situation. The method of sealing is not limited, but if the tube is inserted and heated, it can be in close contact.
[0018]
(D) shows a case where the pad mounting method at the tip of the arm is changed, and the other forms are common to (a). The pad is provided with two legs 17a and 17b so that it can bend inward, and can be attached by pushing it into the attachment ring 18 at the end of the arm.
(E) shows the arm curved in an arc shape. The direction of the pad can be changed with respect to the mounting ring 18 at the tip of the arm. That is, the legs 17 a and 17 b leave a gap between the legs 17 a and 17 b and the mounting ring 18.
[0019]
(F) is similar in form to (e) above, except that the pad mounting structure is slightly different. That is, a notch is provided in a part of the mounting ring 18, and the pad 16 can be fitted from the notch.
In (g), a bearing 19 is provided at the tip of an arm formed of a coil spring, and a spherical shaft 20 formed on a pad 16 is fitted to the bearing 19. Therefore, the pad 16 can be tilted in any direction, and can be engaged with the concave shape of the ear.
[0020]
FIG. 3 is another embodiment showing the form of the crane tip. The tip of the crane has a length adjusting mechanism, and the screw 13 is screwed to the pipe nut 14. The arm 15 which is curved in a substantially L shape is made of a material having excellent elastic deformation, and a pad 16 is attached to a tip of the arm 15. Since the length of the crane 4 is adjustable, the pad 16 is adjusted so that the pad 16 engages with the ear cavity. In this state, the arm 15 can flex freely. Further, the arm 15 has a curved portion 21 so that the pad position can be easily finely adjusted.
[0021]
FIG. 4 shows another embodiment of the crane tip. A pad 16 is attached to the tip of the arm 15 and is the same as the embodiment shown in FIG. 2 except that the length adjusting mechanism of the crane 4 is different. A pipe 22 is provided at the tip of the vine, and a pipe nut 23 is fitted to the pipe 22. A screw 24 is screwed into the pipe nut 23, and a screw tip 25 is conical and sharp and is fitted in a groove 26 formed in the bottom of the pipe.
[0022]
When the screw 24 is loosened, the pipe nut 23 can slide freely along the pipe 22, and the positions of the arm 15 and the pad 16 can be changed. If the screw 24 is tightened when the pad 16 is fixed at a predetermined position, the tip 25 is inserted into the groove 26 and expands to the outer periphery, and the pipe nut 23 expands its outer diameter and is fixed to the pipe 22. .
[0023]
FIG. 5 shows another embodiment of the present invention, which is another embodiment of the vine length adjusting mechanism. A pipe 22 is provided at the tip of the vine, and a shaft 27 is fitted on the pipe 22. The arm 15 extends from the shaft 27 in a curved manner, and a pad 16 is attached to the tip of the arm. An eccentric shaft 28 is provided on a part of the shaft 27, and a lock ring 29 is attached to the outer periphery of the eccentric shaft 27.
[0024]
In the state shown in (a), the shaft 27 is not locked, and the shaft 27 moves in the axial direction along the pipe 22, so that the position of the pad 16 can be determined so as to engage with the recess of the ear. When the shaft 27 is rotated in the direction indicated by the arrow (counterclockwise) at the fixed position, the lock ring 29 fitted on the eccentric shaft 28 is simultaneously rotated to lock the shaft 27. The shaft 27 has a contact 30a extending toward the eccentric shaft 28, and the lock ring 29 also has a contact 30b. Therefore, if the shaft 27 rotates, the contact 30a comes into contact with the contact 30b of the lock ring 30b and is forcibly rotated and locked.
[0025]
The front portion of the eyeglass frame shown in FIG. 1 is configured by connecting both rims 1 and 1 with a connecting member 2 and brazing the outer rims 3 and 3 to the outside of the rim. The form is not limited. For example, it is also possible to adopt a structure in which the rim is a half rim in which a part of the lens fits in the upper half, and the lens is held on the lower side by a water thread.
[0026]
Further, there is a case where both lenses are directly screwed by a connecting member without using a rim, and the outside of the lens is configured as edgeless glasses in which a yoroi is directly screwed. In any case, the vine is attached to the front oyster so that the vine can be folded.
[0027]
FIG. 6 shows the ear 10 in which an engaging portion such as a pad is fitted and engaged. Inside the outer ring 11 which is the contour of the ear 10, there is a concave recess 12 between the outer ring 11 and the opposite ring. The engaging portion 8 at the tip of the crane fits into the recess 12 and does not shift, and of course does not come off. As described above, since the crane of the eyeglass frame of the present invention has the engaging portion at the tip, the following effects can be obtained.
[0028]
【The invention's effect】
The crane of the eyeglass frame of the present invention has an engaging portion such as a pad at the tip thereof, and this engaging portion can be engaged with the outer ring of the ear or the recess inside the outer ring. The crane has an adjustable length, and an engaging portion is provided on an arm bent or curved from the tip of the crane. Therefore, the engaging portion at the tip of the vine correctly engages with the depression of the ear, and even when displaced, the arm made of the elastic material is not deformed and the pain is not given to the depression, and the glasses worn on the face. Is stable. The crane is made of a conventional material, and the arm at the tip is made of a coil spring or a superelastic material, so that the engaging portion properly engages with the recess and an appropriate engaging force is provided by the spring force of the crane. You can multiply by acting.
[0029]
Further, the direction of the engaging portion can be changed, and the fitting portion has a high feeling of fitting with the dent, for example, a silicone resin is used. When the cover is attached to the surface, it can be replaced. The length of the vine is the length of the vine provided at the tip and engaged with the inner ring of the outer ear or the outer ring, which is shorter than the conventional vine, and the glasses are compact when the vine is folded. Therefore, in the case of reading glasses that are always carried, they are convenient to carry because they are not bulky.
