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 it is repeatedly greatly expanded, 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 it is necessary to develop another design having a similar function for a full rim type front frame and the like.

  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-described 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 metal outer front frame via hinges, and a metal inner front frame. a spectacle frame comprising an inner frame comprising a pair of lenses, the bridge of the inner front frame, as well as connecting the pair of rims, extending towards the left and right sides along both rims, both ends the A means connected to the outer front frame is employed.

  The spectacle frame according to claim 2 of the present invention is the spectacle frame according to claim 1, wherein the bridge of the inner front frame has a distance between portions connected to the outer front frame. The means which is 2 times or more with respect to the distance between the parts which have connected is employ | adopted. The eyeglass frame according to claim 3 of the present invention employs means in which the outer front frame is a half rim type in the eyeglass frame according to claim 1 or 2. According to a fourth aspect of the present invention, in the spectacle frame according to any one of the first to third aspects, the inner front frame is a full rim type.

  According to a fifth aspect of the present invention, in the spectacle frame according to any one of the first to fourth aspects, the outer frame includes means having an elastic body in the vicinity of the hinge. doing. According to a sixth aspect of the present invention, the spectacle frame according to any one of the first to fifth aspects employs means in which a nose pad is attached to 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.

BRIEF DESCRIPTION OF THE DRAWINGS It is a spectacles frame which shows an example of implementation of this invention, (a) is a schematic front view, (b) is a schematic side view, (c) is a schematic plan view. It is a schematic perspective view which shows the front part of the spectacles frame of FIG. It is an outer frame of the spectacles frame of FIG. 1, (a) is a schematic plan view, (b) is a schematic front view. It is an inner frame of the spectacles frame of FIG. 1, (a) is a schematic plan view, (b) is a schematic front view. It is explanatory drawing about an inner side frame. It is a schematic perspective view which shows an example of the conventional spectacles frame.

  FIG. 1 shows a spectacle frame 10 as an example of the embodiment of the present invention, in which (a) is a front view, (b) is a side view, and (c) is a plan view. FIG. 2 is a perspective view showing the front part of the spectacle frame 10. The eyeglass frame 10 is composed of an outer frame 20 and an inner frame 50. FIG. 3 shows the outer frame 20 of the spectacle frame 10, (a) is a plan view thereof, and (b) is a front view thereof. 4A and 4B show the inner frame 50 of the spectacle frame 10, wherein FIG. 4A is a plan view and FIG. 4B is a front view.

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

  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 a part of the hinge 30. In this example, the end of the temple 31 is formed in a U shape to form an elastic body 32. The shape of the elastic body 32 is not limited to a 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 full rim type including an armor portion 54 for fixing the lens 60, but may be a ny roll type (half rim type).

Bridge 53 of the inner front frame 51, along with connecting the pair of rims 52 through the connecting fitting 55 is extended toward the left and right sides along both rims 52 further from the connecting portion, both ends 56 Are connected to the outer front frame 21. The connection between the rim 52 and the connecting metal 55, the connection between the connecting metal 55 and the bridge 53, and the connection between the bridge 53 and the outer front frame 21 are preferably brazed.

  As shown in FIG. 5, if the distance between the parts where the rim 52 is connected to the bridge 53 is x and the distance between the parts where the bridge 53 is connected to the outer front frame 21 is y, x and y The preferable relationship can be shown. That is, y is naturally larger than x, but y is preferably at least twice as large as x, particularly preferably between 2.5 times and 3.5 times.

  With such a relationship, even when the temple 31 is greatly opened, almost no force acts on the lens 60. That is, the force is absorbed by the bridge 53 of the outer front frame 21 and the inner front frame 51, and since the connection between the bridge 53 and the rim 52 is a one point, it hardly affects the lens 60. There is no. Furthermore, 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 half rim type or a full rim type, and the inner front frame 51 can be a full rim type or a nyroll type. The temple 31 can be made of metal or resin. 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. The elastic body 32 is provided at the end of the temple 31 and has a U shape. However, the elastic body 32 may be a part of the hinge piece 30 or the armor portion 24 of the hinge 30.
