Description

  The present invention relates to a hinge structure interposed between a temple and a temple constituting eyeglasses for rotatably connecting the temple to the temple and a pair of eyeglasses having the hinge structure.

  2. Description of the Related Art Conventionally, various types of hinge structures have been proposed for rotatably connecting a temple of spectacles to a yoke.

  Among them, a hinge structure called a so-called spring hinge is one in which a spring mechanism (a coil spring, a leaf spring, or the like) is incorporated in a hinge for hinge-connecting a temple of eyeglasses to a hinge. If such a spring hinge is used, the glasses can be worn after the temple is normally opened and the glasses are worn out after being pushed outward without difficulty against the elastic force of the spring mechanism. The temple has the advantage that the temples are properly tightened by the force, so that the eyeglasses can be securely mounted.

  However, many of the above-mentioned hinge structures called spring hinges have a built-in spring mechanism in the hinge (top part), which complicates the configuration and makes assembly work and maintenance troublesome. There was a problem that required.

  In order to solve such a problem, there has been proposed a spring hinge in which a spring mechanism is provided outside a hinge (top part) (for example, see Patent Document 1). More specifically, the spring hinge disclosed in Patent Literature 1 has a cylindrical slider and a coil spring fitted on the base end side of the temple so as to advance and retreat, respectively, and is formed at a predetermined position of the temple. A cylindrical stopper having a female screw on the inner periphery is screwed to the male screw portion. Then, the coil spring is compressed while supporting one end of the coil spring by the stopper, and by utilizing the elastic biasing force of the coil spring in the compressed state, the coil spring is formed at the tip end of the top part attached to the end of the coil. The slider is configured to contact the cam surface in a biased state. With such a configuration, the slider and the cam surface of the top part cooperate, and the temple can be elastically held at the required open / close position with respect to the yoke.

According to the spring hinge having such a configuration, since the spring mechanism (coil spring) is attached to the outside of the top component, the configuration is simplified as compared with the case where the spring mechanism is attached inside the top component. Having. However, in addition to the necessity of forming a cam surface at the tip end of the top part and the large number of required parts, there is a problem that the problem that the assembling work and the maintenance are troublesome is not sufficiently solved.
Japanese Utility Model Registration No. 3022294

  The present invention has been made in order to solve the problems of the prior art, and has a simple configuration with a small number of parts, when the temple is further expanded outwardly from the state normally opened to the yoroi. An object of the present invention is to provide a hinge structure on which an elastic force can act and eyeglasses provided with the hinge structure.

  In order to solve the above problem, the present invention is a hinge structure interposed between a temple and a temple constituting eyeglasses for rotatably connecting the temple to the temple and comprising one end. A first member having a portion attached to the yoke, a shaft member fitted to the other end of the first member, and a rotation of the first member by fitting the shaft member into one end. A second member movably attached to the temple, the other end of which is attached to the temple, the second member having a base extending from the other end of the second member toward the one end; While being connected to the base, the other end is grooved in a direction perpendicular to a plane parallel to the rotation direction of the second member, and the rotation direction of the second member from the one end toward the other end. A wound portion wound along a plane parallel to the Is, there is provided a spectacle hinge structure characterized by comprising: a clamping portion for clamping in a direction perpendicular to a plane parallel to said base in the rotating direction of the second member.

  According to the hinge structure of the present invention, the first member attached to the yoke, the shaft member fitted to the other end of the first member, and the shaft member fitted to one end of the first member Since the second member is rotatably attached to the first member and the other end is attached to the temple, if the hinge structure is used for spectacles, the second member is centered on the shaft member. By rotating the temple, it is possible to rotate the temple with respect to the yoroi. Here, the second member has a base extending from the other end to the one end of the second member, and one end connected to the base, and the other end formed on a surface parallel to the rotation direction of the second member. And a winding part wound in a direction perpendicular to the other direction and wound from one end to the other end along a plane parallel to the rotation direction of the second member. Therefore, when the temple is to be further pushed outward from the normally opened state, an outward force is applied to the base, thereby increasing the diameter of the winding portion connected to the base ( Or smaller), an elastic restoring force (elastic force) acts.

  As described above, according to the present invention, the temple can be further removed from the state in which the temple is normally opened with respect to the yoke with a simple configuration having a small number of parts (consisting of the first member, the shaft member, and the second member). A hinge structure can be obtained in which elastic force can be exerted when the hinge structure is spread out. For this reason, it is possible to put on the spectacles after pushing it outwards comfortably against the elastic force of the winding part, while the temples properly tighten the temporal part by the elastic force after wearing, so There is an advantage that wearing of spectacles becomes possible.

  In addition, the second member includes a holding portion connected to the other end of the wound portion and holding the base in a direction perpendicular to a plane parallel to the rotation direction of the second member. As a result, when a force is applied to the base in the vertical direction (vertical direction in a state of wearing the glasses using the hinge structure according to the present invention), the elastic deformation of the base is suppressed by the clamping portion, and thus the temple There is also an advantage that unnecessary vertical movement is suppressed. In addition, it is also possible to form the base of the second member into a shape that fits the back side of the ear and use it as a temple of glasses as it is.

  The configuration described above is a configuration in which the first member is attached to the yoke and the second member for applying an elastic force is attached to the temple, but in order to solve the above problem, a configuration in which the attachment portions are reversed is adopted. It is also possible.

  That is, the present invention is a hinge structure that is interposed between the temple and the temple constituting the eyeglasses, and is connected to the temple so as to be rotatable with respect to the temple, one end of which is connected to the temple. A first member to be attached; a shaft member fitted to the other end of the first member; and a shaft member fitted to one end portion to be rotatably attached to the first member. A second member having the other end attached to the yoroi, the second member having a base extending from the other end of the second member toward the one end, and one end connected to the base. On the other hand, the other end is grooved in a direction perpendicular to a plane parallel to the rotation direction of the second member, and extends from the one end toward the other end to a plane parallel to the rotation direction of the second member. A winding portion wound along the winding portion, and connected to the other end of the winding portion; And a pinching portion for pinching in a direction perpendicular to a plane parallel to the rotation direction of the second member. It is possible to achieve the effect. In the case of such a configuration, it is also possible to form the first member into a shape adapted to the back side of the ear, and use the first member as it is as a temple of glasses.

  Preferably, the base portion, the winding portion, and the holding portion are formed by a pair of elongated members arranged in a direction perpendicular to a plane parallel to a rotation direction of the second member.

  According to such a configuration, since the base, the winding portion, and the holding portion are formed by the pair of elongated members, the configuration can be made extremely simple. More specifically, a pair of elongate members are juxtaposed in a direction perpendicular to a plane parallel to the rotation direction of the second member, and one end thereof is joined to the base by brazing or the like to form a base. A winding portion is formed by winding the member along a plane parallel to the rotation direction of the second member toward the other end, and the other ends are separated from each other so as to sandwich the base. Thus, it is possible to constitute the holding portion.

  The present invention is also provided as eyeglasses having the hinge structure.

  According to the hinge structure of the present invention, the first member attached to the yoke, the shaft member fitted to the other end of the first member, and the shaft member fitted to one end of the first member Since the second member is rotatably attached to the first member and the other end is attached to the temple, if the hinge structure is used for spectacles, the second member is centered on the shaft member. By rotating the temple, it is possible to rotate the temple with respect to the yoroi. Here, the second member has a base extending from the other end to the one end of the second member, and one end connected to the base, and the other end formed on a surface parallel to the rotation direction of the second member. And a winding part wound in a direction perpendicular to the other direction and wound from one end to the other end along a plane parallel to the rotation direction of the second member. Therefore, when the temple is to be further pushed outward from the normally opened state, an outward force is applied to the base, thereby increasing the diameter of the winding portion connected to the base ( Or smaller), an elastic restoring force (elastic force) acts. As described above, according to the present invention, the temple can be further removed from the state in which the temple is normally opened with respect to the yoke with a simple configuration having a small number of parts (consisting of the first member, the shaft member, and the second member). A hinge structure can be obtained in which elastic force can be exerted when the hinge structure is spread out. For this reason, it is possible to put on the spectacles after pushing it outwards comfortably against the elastic force of the winding part, while the temples properly tighten the temporal part by the elastic force after wearing, so There is an advantage that wearing of spectacles becomes possible. In addition, the second member includes a holding portion connected to the other end of the wound portion and holding the base in a direction perpendicular to a plane parallel to the rotation direction of the second member. As a result, when a force is applied to the base in the vertical direction (vertical direction in a state of wearing the glasses using the hinge structure according to the present invention), the elastic deformation of the base is suppressed by the clamping portion, and thus the temple There is also an advantage that unnecessary vertical movement is suppressed.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  FIG. 1 is a side view showing a state in which a hinge structure according to an embodiment of the present invention is attached to eyeglasses. FIG. 2 is an enlarged top view showing the vicinity of the hinge structure shown in FIG. As shown in FIG. 1 or FIG. 2, the hinge structure 1 according to the present embodiment is interposed between the yoke E and the temple T constituting the glasses G, and includes a first member 11, a shaft member 12, And a second member 13. The second member 13 is configured to rotatably connect the temple T to the yoke E.

  The first member 11 is formed of, for example, a metal material such as titanium or monel, and has one end attached to the yoke E by brazing, an adhesive, or the like. The other end of the first member 11 is provided with a hole (not shown) through which the shaft member 12 is fitted.

  The shaft member 12 according to the present embodiment is a screw member having external threads formed at appropriate locations. The shaft member 12 includes a hole 135a provided at one end (top member 135) of the second member 13 and having an internal thread formed at an appropriate position, and a hole provided at the other end of the first member 11 described above. Each is fitted and screwed with a female screw formed in the hole 135a, thereby connecting the first member 11 and the second member 13.

  As described above, the shaft member 12 is fitted into one end of the second member 13, and the second member 13 is rotatable around the shaft member 12 in the direction indicated by the arrow in FIG. 131) is attached to the temple T.

  More specifically, the second member 13 includes a base 131, a winding part 132, and a holding part 133. In particular, the base 131, the winding part 132, and the holding part 133 according to the present embodiment are juxtaposed in a direction perpendicular to a plane parallel to the rotation direction of the second member 13 (a plane parallel to the plane of FIG. 2). 1 (a hatched member in FIG. 1). The elongated member A is formed of, for example, a metal material such as titanium or monel. The second member 13 according to the present embodiment further includes a plate member 134 and a top member 135.

  The base 131 extends from the other end of the second member 13 (below the sheet of FIG. 2) toward one end (above the sheet of FIG. 2). It is constituted by joining the ends together by brazing, an adhesive or the like. A part of the base 131 is fitted into the temple T (since the temple T according to the present embodiment is formed of a transparent material, the fitted part is visible from the outside). The member 13 is attached to the temple T.

  One end of the winding part 132 is connected to the base 131, while the other end thereof is grooved in a direction perpendicular to a plane parallel to the rotation direction of the second member 13, from the one end to the other end. It is a portion that is wound substantially one turn along a plane parallel to the rotation direction of the second member 13. In particular, the winding part 132 according to the present embodiment is configured such that a portion of the pair of elongated members A that is continuous with the base 131 is directed toward the inside of the glasses G, and the distance between the elongated members A gradually increases. It is configured by winding to increase.

  The holding portion 133 is connected to the other end of the winding portion 132 and is a portion that holds the base 131 in a direction perpendicular to a plane parallel to the rotation direction of the second member 13. The portion of the elongated member A that is continuous with the portion forming the winding portion 132 is separated from the base portion 131 by a substantial thickness, and the base portion 131 is sandwiched therebetween. Further, in particular, in the state where the hinge structure 1 is attached to the spectacles G and the temple T is normally opened (the state shown in FIG. 2), the holding portion 133 according to the present embodiment has a length at which one end thereof comes into contact with the yoke E. Accordingly, a function of suppressing the rotation of the temple T is also achieved.

  The plate-like member 134 is formed of, for example, a metal material such as titanium and monel, and is attached to the holding portion 133 by brazing or an adhesive. In this embodiment, the hinge structure 1 is attached to the glasses G. In the state, it is located outside the holding portion 133. However, it is also possible to adopt a configuration in which the plate member 134 is fitted between the holding portions 133.

  The top member 135 is formed of, for example, an elastic member such as a titanium alloy or a shape memory alloy, and is attached to the plate member 134 by brazing, an adhesive, or the like. It is located inside the holding portion 133. Further, as described above, the top member 135 is provided with a hole 135a in which a female screw is formed at an appropriate position, and the shaft member 12 is inserted into the hole 135a and screwed, so that the top member 135 is formed. Is rotatably connected to the first member 11.

  3A and 3B are explanatory diagrams for explaining the operation of the hinge structure 1 having the above-described configuration. FIG. 3A shows a state in which the temple T is being opened outward, and FIG. (C) shows a state where the temple is normally opened, and (c) shows a state where the temple is further opened outward from the normally opened state. When the temple T is gripped and further opened outward from the state shown in FIG. 3A, one end of the holding portion 133 abuts on the yoro E and rotation is suppressed, and the temple T opens normally as shown in FIG. To a stable state. Next, when the temple T is to be further pushed outward from the normally opened state when wearing the glasses, as shown in FIG. Is added, whereby the winding part 132 connected to the base 131 is deformed so as to have a large diameter, so that an elastic restoring force (elastic force) acts in the direction shown by the arrow.

  As described above, according to the hinge structure 1 according to the present embodiment, the temple T has a simple configuration with a small number of parts (configured by the first member 11, the shaft member 12, and the second member 13). The elastic force can be applied when the is further expanded outward from the state where it is normally opened with respect to the yoke E. For this reason, the spectacles can be worn after being spread outward comfortably against the elastic force of the winding part 132, while the temple T is appropriately tightened on the side of the head by the elastic force after the wearing. This has the advantage that it is possible to reliably wear glasses.

  In addition, the second member 13 is connected to the other end of the winding portion 132 at the beveled position, and has a holding portion 133 that holds the base 131 in a direction perpendicular to a plane parallel to the rotation direction of the second member 13. Therefore, when a vertical force (vertical direction on the paper surface shown in FIG. 1) is applied to the temple T and thus the base 131, the elastic deformation of the base 131 is suppressed by the holding portion 133, and thus the temple T becomes unnecessary. Also, there is an advantage that vertical movement is suppressed.

  In the present embodiment, the configuration has been described in which the other end (base 131) of the second member 13 and the temple T are separate bodies. However, the present invention is not limited to this, and the base 131 of the second member 13 is not limited thereto. May be formed in a shape adapted to the back side of the ear, and the temple may be used as it is.

  Further, in the present embodiment, the base 131, the winding part 132, and the holding part 133 are formed by a pair of elongated members A arranged side by side in a direction perpendicular to a plane parallel to the rotation direction of the second member 13. Although the configuration has been described, the present invention is not limited to this, and the present invention can be formed using a single elongated member processed to have a groove at a predetermined position in the longitudinal direction. Further, it is also possible to adopt a configuration in which the base 131, the winding part 132, and the holding part 133 are formed separately from each other and are joined to each other by brazing, an adhesive, or the like.

  Further, in the present embodiment, the form in which the winding portion 132 is formed toward the inside of the glasses G has been described, but the present invention is not limited to this, and the winding portion 132 may be formed toward the outside of the glasses G. It is possible. In this case, when the temple T is further pushed outward from the normally opened state, the wound portion is deformed so as to have a smaller diameter, and an elastic restoring force (elastic force) acts.

  Further, in the present embodiment, the configuration in which the holding portion 133 has a rotation suppressing function for holding the temple T in a normally opened state (holding the temple T unless a further outward force is applied to the temple T) is provided. Although described, the present invention is not limited to this, and adopts a configuration in which a predetermined locking means is attached to the shaft member 12 or the like, and the temple T is held in a normally open state by the locking means. Is also possible.

  Further, in the present embodiment, the configuration in which the first member 11 is attached to the yoke E and the second member 13 for applying an elastic force is attached to the temple T has been described, but the present invention is not limited to this. As shown in FIG. 4, it is also possible to form a hinge structure 1 'in which the mounting locations are reversed. In FIG. 4, the same components as those in the above-described embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted. However, in the case of the hinge structure 1 'shown in FIG. 4, since the holding portion 133 of the second member 13 does not have the function of suppressing the rotation of the temple T, for example, a predetermined locking means is attached to the shaft member 12 or the like. This makes it necessary to keep the temple T open normally. Further, the first member 11 can be formed in a shape that fits the back side of the ear, and can be used as a temple of spectacles as it is.

FIG. 1 is a side view showing a state in which a hinge structure according to an embodiment of the present invention is attached to eyeglasses. FIG. 2 is an enlarged top view showing the vicinity of the hinge structure shown in FIG. FIG. 3 is an explanatory diagram for explaining the operation of the hinge structure shown in FIG.
