[Industrial applications]

 The present invention relates to eyeglass frames.

[0002]

[Prior art]

 Generally, the eyeglass frame is worn by putting the nose pad on the nose of the wearer and hooking the modern attached to the rear end of the temple part to the ear, so it is normally worn stably and moves or falls off. However, it is easy to move in the vertical direction when performing intense exercise such as sports, and therefore, it is disclosed in Japanese Utility Model Laid-Open No. 1-171418, Japanese Utility Model Laid-Open No. 63-157711, Japanese Patent Laid-Open No. 61-47927, and As disclosed in, for example, Japanese Patent Laid-Open No. 62-11821, there have been proposed eyeglass frames which are variously engineered to withstand a violent movement. All of these are equipped with an auxiliary temple that has the elasticity curved in an arc shape inside (front) of the temple end (modern) or made by another member and connected to the back or side of the base of the wearer's ear. It is designed to be pressed against the head. In such a configuration, since the nose pad puts the face on the front side and the auxiliary vine holds the ear or the temporal region from the rear side, it is possible to obtain a holding force equal to or more than the weight of the spectacle frame. It has the feature that it can be reliably prevented from moving or coming off.

[0003]

[Problems to be solved by the device]

 However, in the conventional eyeglass frames disclosed in the above publications, the auxiliary temples are strongly pressed against the ears or the temporal region of the eyeglasses, so that they are suitable for performing intense exercise such as sports. On the other hand, there is a problem in that it is annoying because it strongly presses the ear or the temporal region even during normal wear. Therefore, there is a demand for the development of an eyeglass frame that allows the user to freely adjust the feeling of pressure on the ears or the temporal region, and that can be used both for daily use and for exercise.

The present invention has been made in view of the above-described conventional problems, and an object thereof is to allow a user to freely adjust the feeling of pressure on the ear or the temporal region. It is to provide a spectacle frame that allows the spectacle frame to be used both for everyday use and for intense exercise.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a first invention is that a bending mechanism is embedded in a modern bent portion integrally provided at a rear end of a temple portion of an eyeglass frame and bent downward. At least a lower side portion of the elastic member forms an elastically deformable portion, and the bending mechanism includes two cored bars that are bendably connected to each other, at least one of which is embedded in the inelastically deformable portion. A second invention is a bending mechanism which is integrally provided at a rear end of a temple portion of an eyeglass frame and is embedded in a bent portion of a modern bent downward, and an elastic member arranged along an inner surface of the modern. And at least a lower portion of the bent portion of the modern forms an elastically deformable portion, and the bending mechanism is composed of two cored bars bendably connected to each other, at least one of which is inside the elastically deformable portion. The elastic member is embedded and protrudes toward the front of the modern when the model is bent forward.

[0006]

[Action]

 In the first and second inventions, the folding mechanism is composed of two bendable cores and is not normally folded, but keeps the stretched state, so that the modern elastic deforming portion can be used as a rear portion of the base of the ear. Alternatively, lightly touch or separate along the temporal region. Therefore, there is little pressure on the ears or the temporal region. During vigorous exercise, bend the elastically deformable part of the modern part forward and press it against the back or side of the base of the ear to firmly secure the modern part. At this time, the other core metal is also bent forward to hold the elastically deformable portion in the bent position. In the second invention, the elastic member is housed along the inner side surface of the bent portion of the modern during normal wear, and when the elastic deformable portion of the modern is bent forward during a heavy exercise, the elastic member protrudes to the front of the modern. It is strongly pressed against the back of the ear root or the temporal region, and its restoring force firmly fixes the modern to the back of the ear root or the temporal region.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is a sectional view of an essential part showing an embodiment of an eyeglass frame according to the present invention, FIG. 2 is an enlarged sectional view of an essential part of a model, and FIG. 3 is a front view of an essential part of a core metal of a bending mechanism. In these figures, 1 is a temple part made of metal, which is a component of a spectacle frame, and the front end of the temple part 1 is a pair of left and right rims for holding a lens (not shown) of a spectacle frame. A hinge (not shown) attached to the outer periphery of the outer peripheral portion of the eyeglasses (not shown) is pivotally attached to the left and right sides via hinges (not shown) so that the rear end 1a of the eyeglass wearer's ear 2 The modern 3 that can be hooked on is integrally provided.

The modern 3 is formed into a substantially “horizontal” shape by bending with an acetate resin, a silicone rubber, a polyamide resin, an epoxy resin, etc., so that the rear end portion 1 a of the temple portion 1 is embedded in a substantially horizontal shape. It is composed of a straight portion 3A and a bent portion 3B which is connected to the rear end of the straight portion 3A and is bent downward. The bent portion 3B becomes gradually thicker downward and convex toward the rear. It is curved like a bow. In addition, the bent portion 3B forms an inelastically deformable portion A whose upper portion of approximately 2/3 is the same as the straight portion 3A and has hardness similar to that of the modern modern eyeglass frame, and the remaining 1/3 lower portion. The portion forms an elastically deformable portion B that is elastically deformable in the front-rear direction and the left-right direction, the bending mechanism 4 is embedded inside, and the elastic member 6 is disposed on the inner side surface 5. In manufacturing the modern 3 in which the lower portion of the bent portion 3B is elastically deformable, first, the linear portion 3A and the inelastically deformable portion A are simultaneously formed from the same material, and then the linear portion 3A and the inelastic portion are not formed. Although it is the same material as the deformable portion A, it can be easily manufactured by changing the amount or kind of the additive or by molding the elastic deformable portion B with another material.

The bending mechanism 4 includes two cored bars 7 and 8 formed in the form of elongated thin plates made of the same metal as the temple part 1, for example, a titanium alloy or a nickel alloy, and these cored bars 7 and 8. And a coupling pin 9 that flexibly connects one end, one core metal 7 is in the non-elastically deformable portion A, the other core metal 8 is in the elastically deformable portion B, and both core metals 7, 8 are connected. The joint portion 12 is embedded in the bent portion 3B so as to be located inside the connection portion 13 of the non-elastically deformable portion A and the elastically deformable portion B, respectively. Pin holes 14 and 15 through which the connecting pin 9 is inserted are formed in the sliding surfaces 7a and 8a of the two cored bars 7 and 8 which are in close contact with each other, and the angle of the elastically deformable portion B in the front-rear direction is set. A plurality of, for example, eight concave portions 16 and convex portions 17 constituting the mechanism are radially formed around the pin holes 14 and 15, respectively. Therefore, the elastically deformable portion B is adapted to be changed in angle by 45 ° in the front-rear direction by fitting the concave portion 16 and the convex portion 17, and in normal wear, as shown by the solid line in FIG. It forms the same straight line or curve as A. The thickness of the cored bars 7 and 8 is about 1 mm, the depth of the recess 16 and the height of the protrusion 17 is about 0.1 mm, and the width of the recess 16 and the protrusion 17 is about 0.2 mm.

A groove 18 is formed on the inner side surface 5 of the bent portion 3B over substantially the entire length of the bent portion 3B in the longitudinal direction, and the elastic member 6 is housed in the groove 18. The elastic member 6 is formed of silicon rubber, neoprene rubber or the like into a plate shape or a tube shape, and only its both ends are fixed to the ends of the groove 18 by suitable fixing means such as screws 19. Therefore, the upper end of the elastic member 6 is connected to the inelastically deformable portion A and the lower end is connected to the lower end of the elastically deformable portion B, and is stretched by about 5 to 10% of its natural length during normal wear. And is housed in the groove 18 as shown in FIG.

In the spectacle frame having such a configuration, when the modern 3 is hung on the ear 2, the inner surface of the straight portion 3A contacts the vicinity of the temporal region of the wearer's head, and the lower surface 31a of the rear end portion of the straight portion 3A is located in the ear. The inner surface 5 of the bent portion 3B hits the back side of the ear 2 and the front end surface 33 of the bent portion 3B hits the back surface of the root 2A of the ear 2. In this case, only the front end face 33 of the inelastically deformable portion A contacts the rear surface of the base of the ear 2 during normal wearing, and the elastically deformable portion B is separated from the rear surface of the base. Therefore, it does not give a great sense of oppression to the wearer. At this time, the cored bars 7 and 8 of the folding mechanism 4 form a straight line, and the elastic member 6 is completely housed in the groove 18 (FIG. 4 (a)). When performing a vigorous exercise with the spectacle frame attached, the elastically deformable portion B is bent forward by a required angle (45 °) as shown by the chain double-dashed line in FIG. It is pressed against the back or the side of part 2A. The bending of the elastically deformable portion B causes the core metal 8 of the bending mechanism 4 to rotate forward 45 ° about the connecting pin 9 as a rotation center, and the convex portion 17 to the other concave portion 16 which is displaced forward 45 °. By fitting, the elastically deformable portion B is stably held at the bending position. Therefore, the modern 3 can be firmly fixed to the rear surface of the base of the ear 2 or the temporal region, and the movement of the spectacle frame and the falling of the spectacle frame are prevented. On the other hand, the elastic member 6 projects forward from the groove 18 as shown by the chain double-dashed line in FIG. Although returning to the state, when the elastically deformable portion B is bent forward while the modern 3 is hooked on the ear 2, it hits the back surface of the base portion 2A of the ear 2 as shown by the thick broken line 35 in FIG. 4 (b). In addition, it elastically deforms along the back surface of the base portion 2A of the ear 2 and becomes longer than the natural state. When the elastic member 6 is elastically deformed and stretched, the restoring force of the elastic member 6 presses the rear surface of the base of the ear 2, so that the modern 3 is more firmly fixed to the ear 2. Therefore, it is possible to sufficiently withstand a vigorous exercise, and it is possible to reliably prevent the spectacle frame from being displaced or dropped.

The present invention is not limited to the above-described embodiment, and various changes and modifications are possible. For example, the elastic member 6 may not be provided. In that case, the elastically deformable portion B may be largely bent to the front side so that the elastically deformed portion B is strongly bited into the back surface of the base of the ear 2 or the temporal region. Further, the present invention is configured to variably set the bending angle of the elastically deformable portion B by fitting the concave portions 16 and the convex portions 17 provided on the sliding surfaces 7a and 8a of the cored bars 7 and 8, so that it can be set only step by step. It cannot be variably set, and the cored bar 8 moves in the plate thickness direction when the concave portion 16 and the convex portion 17 are disengaged from each other. However, if the angle is set by the friction mechanism, the angle can be freely set. This has the advantage that the pressure on the ears or the temporal region can be adjusted delicately and that the cored bar 8 can be rotated in the same plane. As the friction mechanism, the sliding surfaces 7a and 8a may be pressed against each other via a friction member such as felt. Furthermore, in the present embodiment, an example in which the lower part of the modern is used as the elastically deformable portion has been shown, but the present invention is not limited to this, and the entire modern may be made of elastically deformable material.

[0013]

[Effect of device]

 As described above, the spectacle frame according to the present invention has at least the lower part of the modern part as the elastically deformable part, the bending mechanism is embedded inside, and the elastically deformable part is the rear part of the base of the ear during normal wear. Alternatively, it is configured so that it is lightly contacted with or separated from the temporal region, and the elastically deformable portion is bent forward and pressed against the back of the ear root or the temporal region during heavy exercise, so that it can be worn during normal wear. There is almost no feeling of pressure, and one spectacle frame can be used for both normal and intense exercise. Further, in addition to the bending mechanism, the present invention arranges an elastic member along the inner surface of the modern, and elastically deforms this elastic member at the time of vigorous motion to press it against the back of the ear root or the temporal region. With this configuration, the modern can be more firmly fixed to the ear or the temporal region, and it is possible to reliably prevent the spectacle frame from slipping off or falling off.
