Description

  The present invention relates to a spectacle frame, and more particularly, to a spectacle frame that does not affect a lens even when a temple is greatly opened.

  In general, in a spectacle frame, temples are connected to both ends of a front frame holding a pair of lenses via hinges. As the front frame, there is a rimless type called a full rim type, a half rim type, or a two-point type.

  When the user normally uses a spectacle frame, the user is using the temple in a state where the temple is expanded to the maximum with respect to the front frame (maximum expanded state). In other words, when a user purchases a spectacle frame, the degree of opening of the hinges and the degree of bending of the temples are adjusted so that the temple does not exert a large force on the head and the head is closely attached to the head. I have to.

  However, when wearing or removing eyeglasses, the user unconsciously unfolds the temple much larger than the maximum expanded state. For this reason, if the spectacle frame is used for a long period of time, the temple will gradually not come into close contact with the head, which will hinder use. In some cases, a large force acts on the front frame to damage the lens.

  For example, Patent Document 1 describes a spectacle frame in which no force is applied to a lens even when a temple is greatly opened. As shown in FIG. 6, the spectacle frame 110 has an L shape, and a pair of left and right lens stays 122 that hold the inner portion of the lens 160, a bridge 123 that connects the pair of lens stays 122, and a lens A long armor portion 124 connected to each stay 122 and a temple 131 connected to the armor portion 124 via a hinge 130 so as to be foldable. Both lens stays 122 hold a lens 160. 162 is attached.

  Here, the lens 160 is attached to the lens stay 122 at one point by a lens stopper 162. For this reason, even when the temple 131 is opened wide, almost no force acts on both lenses 160. In addition, since the long armor portion 124 has elasticity together with the temple 131, even if large expansion is repeated, it can be within the elastic range of the temple 131 and the armor portion 124.

  However, only the invention described in Patent Document 1 has a limited design width and cannot be applied to a full rim type front frame made of resin, and other designs having similar functions have been developed. There is a need to.

JP 2008-76743 A

  Accordingly, an object of the present invention is to provide a spectacle frame in which even when the temple is opened wide, almost no force acts on the lens, and has a novel design and can be further expanded. It is in.

  In order to solve the above-mentioned problems, an eyeglass frame according to claim 1 of the present invention includes an outer frame in which temples are connected to both ends of a resin outer front frame via a hinge, and a metal inner front frame. An eyeglass frame comprising an inner frame comprising a pair of lenses, wherein the outer frame comprises a recess on the inner side of the bridge, the inner frame comprises a convex on the outer side of the bridge, and the convex A means for inserting and fixing in the recess is employed.

  The eyeglass frame according to claim 2 of the present invention employs means in which the outer front frame is a full rim type in the eyeglass frame according to claim 1. According to a third aspect of the present invention, in the spectacle frame according to the first or second aspect, the inner front frame is a nyroll type.

  According to a fourth aspect of the present invention, there is provided the spectacle frame according to any one of the first to third aspects, wherein the outer frame is provided with an elastic body in the vicinity of the hinge. doing. According to a fifth aspect of the present invention, in the spectacle frame according to any one of the first to fourth aspects, the nose pad is mounted on the inner front frame. .

  By adopting the above-described configuration, the spectacle frame of the present invention is a spectacle frame that is practical and has a novel design, and can open the temple greatly without exerting almost any force on the lens. it can. In addition, the design can have a wider variety.

It is a schematic plan view of the spectacles frame which shows an example of implementation of this invention. It is a schematic side view of the spectacles frame of FIG. It is a schematic front view of the spectacles frame of FIG. It is a schematic front view of the inner side frame of the spectacles frame of FIG. It is a schematic plan view which shows the state which cut | disconnected the inner frame of the spectacles frame of FIG. 1 from the outer frame. It is a schematic perspective view which shows an example of the conventional spectacles frame.

  1 to 3 show a spectacle frame 10 which is an example of an embodiment of the present invention. FIG. 1 is a plan view, FIG. 2 is a side view, and FIG. 3 is a front view. The eyeglass frame 10 is composed of an outer frame 20 and an inner frame 50. FIG. 4 is a front view of the inner frame 50, and FIG. 5 shows a state in which the inner frame 50 is separated from the outer front frame 21 of the outer frame 20.

  That is, the eyeglass frame 10 has a normal full rim type appearance at first glance, but is constituted by the outer frame 20 and the inner frame 50. The outer frame 20 includes an outer front frame 21, a hinge 30 and a temple 31, and the inner frame 50 includes an inner front frame 51 and a pair of lenses 60.

  The outer front frame 21 is made of resin, a pair of rims 22 are connected by a bridge 23, and a temple 31 is rotatably attached to an armor part 24 constituting both ends thereof via a hinge 30. In this example, the outer front frame 21 is shown as a full rim type, but it can also be a half rim type. Further, the temple 31 is made of resin, but it can be made of metal.

  The hinge 30 enables the temple 31 to rotate with respect to the outer front frame 21 and restricts the rotation range thereof. That is, when the spectacle frame 10 is in use, the eyeglass frame 10 is not rotated more than the maximum spread state. When the spectacle frame 10 is not in use, the temple 31 is folded inward so that it can be stored in the case.

  The outer frame 20 preferably includes an elastic body 32 in the vicinity of the hinge 30. Here, the vicinity of the hinge 30 includes a part of the armor portion 24, a part of the temple 31, and the hinge 30 itself. In this example, the butterfly piece on the armor portion 24 side of the hinge 30 is formed in a U-shape to form the elastic body 32. The shape of the elastic body 32 is not limited to the U shape, and may be an S shape.

  The elastic body 32 is preferably elastically deformable at an angle of at least 10 °. Accordingly, when the user wears or removes the spectacle frame 10, the user can open the lens frame 10 more than 10 ° on one side, and can prevent the lens 60 from being damaged. .

  As shown in FIG. 4, the inner front frame 51 of the inner frame 50 is made of metal, a pair of rims 52 are connected by a bridge 53, and a pair of lenses 60 are attached. In this example, the inner front frame 51 is shown as a nyroll type (half rim type), but may be a full rim type.

  The rim 52 of the illustrated inner front frame 51 is formed shorter than a normal half rim type, and is composed only of a portion close to the user's nose. That is, the length of the rim 52 is about a quarter of the outer circumference of the lens 60. Such an inner front frame 51 is easy to manufacture because there are few portions that match the shape with the lens 60, and is particularly advantageous when the curvature of the lens 60 surface is large.

  FIG. 5 shows a state in which the inner frame 50 is separated from the outer frame 20 and shows a method of joining the inner frame 50 and the outer frame 20. The inner frame 50 includes a convex portion 55 on the outer surface of the bridge 53 (surface on the outer frame 20 side), and the outer frame 20 includes a concave portion 25 on the inner surface of the bridge 23 (surface on the inner frame 50 side). . And the convex part 55 can be inserted in the recessed part 25, and can be fixed. As a fixing method, a method by adhesion is also possible. However, the lens 60 can be easily replaced by screwing as shown in the figure.

  The eyeglass frame 10 of the present invention is connected by a bridge 23 of the outer frame 20 and a bridge 53 of the inner frame 50. The temple 31 is connected to the outer frame 20, and the lens 60 is attached to the inner frame 50. For this reason, even if the temple 31 is opened largely, the force does not affect the lens 60. Further, by providing the elastic body 32 in the vicinity of the hinge 30, the influence can be further reduced.

  Further, the outer front frame 21 can be a full rim type or a half rim type, and the inner front frame 51 can be a nyroll type or a full rim type. The temple 31 can be made of resin or metal. Therefore, the design has a wide variety.

  In the eyeglass frame 10, an example in which the nose pad 61 is attached to the inner front frame 51 is shown, but it can also be attached to the outer front frame 21. Further, although the elastic body 32 has a U-shaped butterfly piece on the armor portion 24 side of the hinge 30, the butterfly piece on the temple 31 side can be formed in a U-shape. A part of the temple may be U-shaped.
