Description

  The present invention relates to a spectacle frame in which a rim constituting a front portion of spectacles is composed of a front rim and a back rim.

  FIG. 4 shows a conventional general eyeglass frame. The eyeglass frame in the figure is made of metal, (a) represents the front part, (b) represents the crane, and the front part (b) is connected to the rim (d) and (d) connected by the connecting member (c). ) And armor (e) and (e) fixed on both sides. The armor (e) and (e) have hinges (e) and (e) through the hinges (e) and (e). It is installed so that it can be folded.

  By the way, the lens (g) is attached to the rim (d) provided in the front part (b), but the screw of the broach provided hidden behind the rear part of the armor can be loosened and fitted. That is, by loosening the screw of the broach, the circumference of the rim is enlarged, and in this state, the lens is fitted and tightened again. Although the lens (g) is bent into a predetermined shape so that the lens (g) fits on the inner periphery of the rim, a slight size and shape error imposes excessive stress on the lens (g). For this reason, chipping of the lens (g) and lens cracking occur.

  FIG. 5 is an enlarged cross-sectional view taken along the line AA in FIG. 4. A groove (chi) is provided on the inner periphery of the rim, and the lens outer periphery is fitted and attached to the groove (chi). The lens surface is curved with a predetermined curvature, and the outer periphery is substantially elliptical. The shape of the rim (d) on which the outer periphery of the lens (g) fits must be curved in a three-dimensional shape, and generally the lens outer periphery does not fit completely without a gap.

  That is, the outer periphery of the lens is partially in contact with the inner peripheral surface (re) of the rim, and if the broach is tightened, the contact surface pressure becomes extremely large, and if the front part (A) is bent or twisted, it is even larger. It becomes surface pressure. This causes lens breakage.

  On the other hand, the design of the front part (a), which occupies the largest part of the glasses, is restricted, and the rim shape of the ellipse can be changed in various ways, but the surface of the rim (d) composed of thin ring-shaped wire rods The limit is to color plate or paint.

  As described above, the front part having a rim formed by bending one wire has the above-described problems. The problems to be solved by the present invention are these problems, and provide a front part of eyeglasses that can be applied in various designs without exerting excessive force on the lens.

  The glasses according to the present invention are characterized by the front part thereof. Therefore, the rim is not composed of one thin wire rod, but is composed of a front rim and a back rim, and the lens outer periphery is sandwiched between the front rim and the back rim. Here, the front rim and the back rim may be formed by bending a wire, or may be formed by processing a thin plate material such as punching and cutting.

  On the other hand, the front rim and the back rim may be configured integrally with the front front plate and the back front plate. The front rim and the back rim sandwich the lens and are connected via a stopper or a screw. Here, the front rim and the back rim are formed symmetrically by the connecting portion, but the shape of the stopper is not limited.

  In the present invention, the front rim is composed of a front rim and a back rim, and the outer periphery of the lens can be sandwiched between both rims. Therefore, a conventional broach for tightening a generally elliptical rim composed of a single wire is not required, and the lens outer periphery is sandwiched from both sides, so that the lens is not overwhelmed, and the occurrence of lens chipping or lens cracking is eliminated. Can be suppressed. If the thickness of the front rim and the back rim is reduced, it can be deformed to fit both sides of the lens, and the lens is not overwhelmed.

  On the other hand, since the rim is composed of a front rim and a back rim, the colors of both rims can be changed, and the color design of the front part can be diversified. Moreover, although the inner peripheral surface of a front rim and a back rim has the same dimension, the outer periphery does not necessarily need to be the same shape, and the design of a shape surface can be diversified by changing an external shape.

  FIG. 1 is a front view of an eyeglass frame according to the present invention, and FIG. 2 is a development view. In the figure, reference numeral 1 denotes a front part of the glasses, 2 denotes a temple, and the temples 2 and 2 are attached so as to be foldable on both sides of the front part 1. By the way, the front part 1 has rims 3 and 3 and a connecting part 4, and both the rims 3 and 3 are formed symmetrically about the connecting part 4.

  In the case of the present invention, the front portion 1 includes a front front plate 5 and a back front plate 6, and the front front plate 5 and the back front plate 6 are joined to each other. The front front plate 5 has front rims 7, 7 connected by a front connecting portion 9, and the back front plate 6 has back rims 8, 8 connected by a back connecting portion 10. The front front plate 5 and the back front plate 6 shown in the figure can be manufactured by cutting or cutting a thin metal plate or resin plate.

  The front connecting portion 9 and the back connecting portion 10 have long and narrow front grooves 11 and 12 passing through the front connecting plate 9 and the back connecting plate 10. Grooves 14 and 14 are formed. By the way, the front front plate 5 and the back front plate 6 are overlapped and joined to each other, and in this state, the stopper 15 is fitted into the front groove 11 and the back groove 12 formed in the front connecting portion 9 and the back connecting portion 10 from the front side. The lock piece 16 is fitted from the back side.

  The stopper 15 extends two legs 17, 17, and has a claw protruding outward at the leg tip. Both legs 17, 17 of the stopper 15 penetrate the front groove 11 and the back groove 12, The claw is engaged with both sides of the back groove 12. If the lock piece 16 is fitted between the legs 17, 17, the stopper 15 cannot be removed.

  Similarly, the front front plate 5 and the back front plate 6 are connected and fixed by stoppers 18 and 18 provided on the temples 2 and 2 on both sides of the front portion 1. That is, two legs 19 and 19 are extended to the stopper 18, and a claw is projected outward from the leg tip. Therefore, both legs 19, 19 pass through the back groove 14 and the front groove 13 and the claw is locked to the edge of the front groove 13. And the stopper 18 is fixed without removing by fitting the lock piece 20 between the both legs 19 and 19 from the front side.

  The stopper 18 not only connects the front front plate 5 and the rear front plate 6 but also has a function of attaching the temple 2 to the front portion 1. Further, a joint portion 21 is provided between the stopper 18 and the temple 2, and the temple 2 is folded via the joint portion 21.

  By the way, the front front plate 5 and the back front plate 6 have slightly different external shapes. Although the front rim 7 and the back rim 8 have the same size and shape on the inner periphery of the rims 3 and 3 to which the lens fits, the outer shapes are different as shown in FIG. That is, since the front front plate 5 is smaller than the back front plate 6, a part of the back front plate 6 is surfaced when viewed from the front.

  FIG. 3 is an enlarged vertical cross-sectional view in which the lens 22 is fitted to the rim 3, and the inner circumference of the front rim 7 and the back rim 8 has inclined surfaces 23, 23. The lens 22 is fitted into the groove 24 to be formed. The front front plate 5 and the back front plate 6 are made of thin plates, can sandwich the lens 22 from both sides, and can be held stably without overloading the lens 22.

  The front front plate 5 and the back front plate 6 formed of thin plates can be deformed by being familiar with the lens 22, and the outer periphery of the lens is held in close contact with the inclined surfaces 23 and 23. Therefore, the lens 22 does not fall off from the front portion 1.

  By the way, the front part 1 configured by superimposing the front front plate 5 and the back front plate 6 can be diversified in design. This is one of the major features of the present invention. For example, the front portion 1 that does not exist in the prior art can be configured by changing the outer shapes of the front front plate 5 and the back front plate 6. It is also possible to change the colors of the front front plate 5 and the back front plate 6.

  The front front plate 5 and the back front plate 6 constituting the front part 1 are made of metal or resin, but may be different from each other. For example, the front front plate 5 may be made of metal and the back front plate 6 may be made of resin, or conversely, the front front plate 5 may be made of resin and the back front plate 6 may be made of metal.

  And the means to connect the front front board 5 and the back front board 6 is not restricted to the fasteners 15 and 18 shown in FIG. 2, but can also be screwed. In the embodiment, the front portion 1 is composed of the front front plate 5 and the back front plate 6, but there may be a structure in which two back rims 8, 8 are joined to the back side of the front front plate 5. Further, two front rims can be attached to the surface of the back front plate 6. That is, the lens 22 may be sandwiched between two front rims 7 and 7 or two back rims 8 and 8 separated from each other on either the front side or the back side.
