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. An eyeglass frame comprising an inner frame having a pair of lenses, wherein the inner front frame includes a bridge connecting a pair of rims, and the outer front frame does not include a bridge connecting a pair of rims. The bridge of the inner front frame and the pair of rims of the outer front frame are connected by a pair of elastic bodies.

  The spectacle frame according to claim 2 of the present invention is the spectacle frame according to claim 1, wherein a distance between outer ends connected to the outer front frame in the pair of elastic bodies is the bridge. The means which is 3 times or more with respect to the distance between the inner end parts connected is 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 nyroll 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 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.

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. The outer frame of the spectacles frame of FIG. 1 is shown, (a) is a schematic plan view, (b) is a schematic front view. 1 shows both an inner frame and an elastic body of the eyeglass frame of FIG. 1, (a) is a schematic plan view, and (b) is a schematic front view. It is explanatory drawing about an inner side frame and an elastic body. 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. 3A and 3B show the outer frame 20 of the spectacle frame 10, wherein FIG. 3A is a plan view and FIG. 3B is a front view. 4A and 4B show both the inner frame 50 and the elastic body 70 of the eyeglass frame 10, wherein FIG. 4A is a plan view and FIG. 4B is a front view.

  That is, the spectacle frame 10 has a normal half-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 frame 20 and the inner frame 50 are connected and integrated by a pair of elastic bodies 70.

  The outer front frame 21 is made of metal, and a temple 31 is rotatably attached to an armor portion 24 constituting both ends of the pair of rims 22 via a hinge 30. However, since the bridge that connects the rims 22 is not provided inside the pair of rims 22, the outer frame 20 alone is in a state of being separated left and right. 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.

  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.

  The bridge 53 of the inner front frame 51 and the rim 22 of the outer front frame 21 are connected by a pair of elastic bodies 70. That is, the inner end 71 of the elastic body 70 is fixed to the bridge 53 and the outer end 72 is fixed to the rim 22. Since the elastic body 70 is formed along the rim 22, when the eyeglass frame 10 is viewed from the front, it appears as if the bridge 53 and the rim 22 integrally form a front frame.

  As shown in FIG. 5, the distance between the inner ends 71 where the elastic body 70 is connected to the bridge 53 is x, and the distance between the outer ends 72 where the elastic body 70 is connected to the outer front frame 21. When y is set, a preferable relationship between x and y can be shown. That is, although y is naturally larger than x, y is preferably 3 times or more of x, and particularly preferably between 4 times and 6 times.

  Since the spectacle frame 10 of the present invention is configured as described above, when the temple 31 is greatly opened, the force acts on the outer end 72 of the elastic body 70 from the rim 22 of the outer front frame 21. Will do. Therefore, although the elastic body 70 is deformed as a whole, the inner end 71 of the elastic body 70 is fixed to the highly rigid bridge 53, so that the force does not act further. As a result, even if the temple 31 is opened widely, the lens 60 is not affected at all.

  Although the spectacle frame 10 of the present invention has a very novel design, it is not unusual and is a design accepted by anyone. 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 nyroll type or a full rim type. The temple 31 can be made of metal or resin. Therefore, a wide variation is provided.

  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 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 the user to buy the glasses frame, to adjust the curvature of the hinge of the open condition and the temple, the temple rather than the name to exert a large force to the head, also, to as to be in close contact with the head ing.

  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.

A spectacle frame according to a fifth aspect of the present invention employs the spectacle frame according to any one of the first to fourth aspects, wherein a nose pad is attached to the inner 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. The outer frame of the spectacles frame of FIG. 1 is shown, (a) is a schematic plan view, (b) is a schematic front view. 1 shows both an inner frame and an elastic coupling body of the spectacle frame of FIG. 1, (a) is a schematic plan view, and (b) is a schematic front view. It is explanatory drawing about an inner side frame and an elastic coupling body. 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 spectacle frame 10 of the present invention is characterized by being composed of an outer frame 20 and an inner frame 50. 3A and 3B show the outer frame 20 of the spectacle frame 10, wherein FIG. 3A is a plan view and FIG. 3B is a front view. 4A and 4B show both the inner frame 50 and the elastic coupling body 70 of the spectacle frame 10, wherein FIG. 4A is a plan view and FIG. 4B is a front view.

That is, the spectacle frame 10 has a normal half-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 outer front frame 21 is configured by a pair of left and right outer rims 22 having armor portions 24. The inner frame 50 includes an inner front frame 51 and a pair of lenses 60 , and the inner front frame 51 includes a pair of left and right inner rims 52 and a bridge 53. The outer frame 20 and the inner frame 50 are connected and integrated by an elastic connecting body 70.

The pair of left and right outer rims 22 are provided to be separated from each other, and a temple 31 is rotatably attached to an armor portion 24 constituting each outer end portion via a hinge 30. However, since the inside of the pair of outer rims 22 is not provided with a bridge that connects the outer rims 22, the outer frame 20 is in a state where the left and right are separated separately. In this example, the outer rim 22 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 rim 22 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.

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

Trim 52 among which is illustrated, is formed shorter than usual half rim type, it is constituted only by a portion close to the user's nose. That is, the length of the inner rim 52 is about a quarter of the outer periphery 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.

The inner frame 50 and the outer frame 20 are integrated by connecting the bridge 53 and the outer rim 22 with an elastic connecting body 70. That is, the elastic coupling body 70, the inner-side fixing portion 71 is fixed to the bridge 53, the outer-side fixing portion 72 is fixed to the outer rim 22. Since the elastic coupling body 70 is formed along the outer rim 22, when the eyeglass frame 10 is viewed from the front, the bridge 53 and the outer rim 22 integrally form a front frame. Looks like.

As shown in FIG. 5, the distance between the inner-side fixing portion 71 in which the elastic connecting member 70 is connected to the bridge 53 and x, between the outer-side fixing portion 72 in which the elastic connecting member 70 is connected to the outer rim 22 If the distance of y is y, a preferable relationship between x and y can be shown. That is, although y is naturally larger than x, y is preferably 3 times or more of x, and particularly preferably between 4 times and 6 times.

Spectacle frame 10 of the present invention, by which the above-described structure, when the wide open temple 31, the force, the outer-side fixing portion 72 of the elastic connecting member 70 from the outer rim 22 of the outer frame 20 Will act. Thus, the entire elastic coupling body 70 will be deformed, since the inner-side fixing portion 71 of the elastic connecting member 70 is fixed to a high bridge 53 rigid, the force is not acting on more . As a result, even if the temple 31 is opened widely, the lens 60 is not affected at all.

Although the spectacle frame 10 of the present invention has a very novel design, it is not unusual and is a design accepted by anyone. The outer rim 22 can be a half rim type or a full rim type, and the inner rim 52 can be a nyroll type or a full rim type. The temple 31 can be made of metal or resin. Therefore, a wide variation is provided.
