Description

[Technical field]

[0001] The present invention relates to flip-up eyeglasses. [Background technology]

[0002] Flip-up glasses are glasses in which the front part that holds the lenses is attached so that it can rotate up and down around the axis of the frame. Flip-up glasses have been widely known for some time. For example, flip-up reading glasses and flip-up sunglasses are known. Flip-up glasses are classified into two types: those with a single structure in which the lenses are only provided on the front part, and those with a double structure in which the lenses are provided on the front part and the frame.

[0003] An example of a conventional technique for flip-up glasses is the invention described in Patent Document 1. The flip-up glasses 10 described in Patent Document 1 include first lenses 11L, 11R, a holding frame 20 that holds the first lenses 11L, 11R, a front bar 30, hinges 50L, 50R fixed to the holding frame 20 and the front bar 30, respectively, end pieces 70L, 70R provided at each end of the front bar 30, and temples 71L, 71R connected to the end pieces 70L, 70R by hinges 72L, 72R.

[0004] The front bar 30 is formed by a first bar portion 31 disposed in the center, second bar portions 33L, 33R connected to the left and right ends of the first bar portion 31, first bent portions 35L, 35R, second bent portions 37L, 37R, and third bar portions 39L, 39R. The second bar portions 33L, 33R are curved rearward in the front-rear direction in a plan view from the center side in the width direction of the front bar 30 toward the ends.

[0005] The hinges 50L, 50R are provided on the second bar portions 33L, 33R. The hinges 50L, 50R are symmetrical. The hinge 50L includes a first link piece 51L, a second link piece 57L, and an axis portion 60L. The first link piece 51L is fixed to a portion of the second bar portion 33L that curves rearward in the front-rear direction, with the hinge 50L adjacent to the third bar portion 39L on the right side in the width direction. The portion of the second bar portion 33L to which the first link piece 51L is fixed is the surface that faces the front in the front-rear direction.

[0006] By adopting such a configuration, the flip-up glasses 10 of Patent Document 1 can increase the flip-up distance of the first lenses 11L, 11R in the flip-up state, thereby preventing the first lenses 11L, 11R from entering the user's field of vision. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2017-026957 A Summary of the Invention [Problem to be solved by the invention]

[0008] The flip-up eyeglasses 10 of Patent Document 1 have a front bar 30 formed by a first bar portion 31, second bar portions 33L, 33R, first bend portions 35L, 35R, second bend portions 37L, 37R, and third bar portions 39L, 39R, and the hinges 50L, 50R are fixed to the curved portions on the rear side in the front-to-rear direction, thereby increasing the flip-up distance of the first lenses 11L, 11R.

[0009] For this reason, in the prior art, in order to increase the lift distance of the lens provided in the front section, a bent portion had to be formed in the front bar of the frame body, which resulted in a problem of the shape of the front bar becoming complex.

[0010] An object of the present invention is to provide flip-up eyeglasses that can increase the distance the lenses can be flipped up without complicating the shape of the front bar. [Means for solving the problem]

[0011] The present invention is a pair of flip-up glasses having a frame body and a front portion that is rotatably connected to the frame body, the front portion having a retaining frame that holds a front lens and a connecting piece that is connected to the frame body, the frame body having a front bar extending in the left-right direction of the user's face, end pieces provided at each end of the front bar, connecting pieces that are rotatably connected to the connecting piece, and temples that are connected to the end piece via hinges, and when the front portion is lowered, the connecting piece is provided at the upper part of the frame body and has a bearing portion formed to protrude rearward from the frame body and an axis portion that is inserted into the bearing portion, and the connecting piece has one end connected to the front portion and the other end connected to be rotatable around the axis of the axis portion.

[0012] In the present invention, the connecting piece is connected to an upper portion of the front portion, and is connected to the connecting portion across an upper portion of the frame body.

[0013] In the present invention, the height dimension of the connecting piece and the height dimension of the connecting portion are the same.

[0014] In the invention it is preferable that the front body holds a frame side lens. Effect of the Invention

[0015] According to the present invention, when the flip-up type glasses have the front portion lowered, the connecting portion is provided on the upper part of the frame body and has a bearing portion formed so as to protrude rearward from the frame body, and an axle portion inserted into the bearing portion, and the connecting piece has one end connected to the front portion and the other end connected so as to be freely rotatable around the axis of the axle portion.

[0016] By adopting this configuration, the rotation axis of the connecting piece can be provided on the rear side of the frame body, which allows the front part to be lifted up a longer distance. Therefore, the lens can be lifted up a longer distance without complicating the shape of the front bar. This prevents the front part from entering the user's field of vision.

[0017] Furthermore, according to the present invention, the connecting piece is connected to the upper part of the front portion and is connected to the connecting portion across the upper part of the frame body, so that the connecting piece can be formed approximately horizontally from the upper part of the front portion.

[0018] By adopting such a configuration, the height dimension of the connecting piece can be reduced, so that the connecting piece is prevented from being noticeable when the flip-up type eyeglasses are viewed from the front with the front part not flipped up.

[0019] Furthermore, according to the present invention, the height dimension of the connecting piece and the height dimension of the connecting portion are the same dimension.

[0020] By adopting such a configuration, the height dimensions of the connecting piece and the connecting part are made the same, and when the flip-up type eyeglasses are viewed from the front with the front part not flipped up, the connecting piece and the connecting part can be prevented from being noticeable.

[0021] Furthermore, according to the present invention, since the front body holds the frame-side lenses, even in the case of compound flip-up type glasses, the lens flip-up distance can be increased without complicating the shape of the front bar. [Brief description of the drawings]

[0026] <Frame body> The front bar 7 extends along the left-right direction of the user's face. The front bar 7 has a pair of side bars 7a, 7b formed in a roughly semicircular arc shape when viewed from the front, and an intermediate bar 7c disposed between the side bars 7a and 7b and connecting the side bars 7a and 7b. A nose pad 12 is provided below the intermediate bar 7c.

[0027] An end piece 8 is provided at the left end of side bar 7a, to which a temple 10 is attached by a hinge 11. Similarly, an end piece 8 is provided at the right end of side bar 7b, to which a temple 10 is attached by a hinge 11. A left connecting part 9a is provided at the top of side bar 7a. A right connecting part 9b is provided at the top of side bar 7b. A tip cell 13 is attached to the free end of temple 10.

[0028] <Front section> The holding frame 5 is composed of upper frames 51, 52, lower frames 53, 54, and an intermediate portion 55 provided between the upper frame 51 and the upper frame 52 and connecting the upper frame 51 and the upper frame 52. The upper frame 51 and the lower frame 53 are connected by a connecting portion 56 to form a frame body, which holds the lens 4 for the right eye. The upper frame 52 and the lower frame 54 are connected by a connecting portion 57 to form a frame body, which holds the lens 4 for the left eye. A left connecting piece 6a is provided at the top of the upper frame 51. A right connecting piece 6b is provided at the top of the upper frame 52. The lens 4 may be a prescription lens or may be a pair of sunglasses.

[0029] <Connection part> 4 is a diagram showing the connecting portion 9. (a) is an enlarged right cross-sectional view showing the connecting portion 9b, and (b) is an enlarged plan view showing the vicinity of the connecting portion 9b. The connecting portions 9a and 9b of the connecting portion 9 are formed to have the same shape. Here, the connecting portion 9b will be described.

[0030] The connecting portion 9b is provided at the top of the frame main body 2 (see FIG. 2(b)), and has bearing portions 91, 92 formed to protrude rearward from the frame main body 2, and a shaft portion 93 inserted into the bearing portions 91, 92. The bearing portions 91, 92 are provided at intervals in the left-right direction equal to the thickness dimension of the connecting piece 6, and each has a through hole 94 through which the shaft portion 93 is inserted (see FIG. 3(b)). A screw groove is formed in the through hole 94 of the bearing portion 92. In this embodiment, the shaft portion 93 is realized by a screw. The bearing portions 91, 92 are connected by a plate-shaped connecting portion 95. A concave space that accommodates the bearing portion 62 of the connecting piece 6b is formed by the bearing portions 91, 92 and the plate-shaped connecting portion 95.

[0031] The bearing portions 91, 92 are formed to have the same shape. Here, the bearing portion 91 will be described. The bearing portion 91 is formed to protrude rearward from near the top of the frame main body 2. The bearing portion 91 has an inclined surface portion 31 that is connected to the surface of the top of the frame main body 2 and inclines upward, a flat portion 32 that is connected to the underside of the top of the frame main body 2 and extends rearward, and an arc portion 33 having one end connected to the inclined surface portion 31 and the other end connected to the flat portion 32. The distance between an imaginary horizontal line including the top of the arc portion 33 and an imaginary horizontal line including the flat portion 32 is defined as the height H1 of the bearing portion 91.

[0032] <Connection piece> 5 is a diagram showing the connecting piece 6. (a) is a right-side cross-sectional view showing the connecting piece 6, and (b) is an enlarged right-side view showing the state in which the connecting piece 6 and the connecting portion 9 are connected.

[0033] The connecting piece 6 has one end connected to the front portion 3 and the other end connected to the connecting portion 9 so as to be rotatable around the axis of the shaft portion 93. The connecting piece 6 has a base end portion 61 connected to the front portion 3, a bearing portion 62 connected to the connecting portion 9, and an intermediate portion 63 connecting the base end portion 61 and the bearing portion 62. A through hole 64 is formed in the bearing portion 62, penetrating in the left-right direction. The shaft portion 93 is inserted into the through hole 64.

[0034] The base end 61 is formed to extend rearward from near the apex of the front portion 3. The base end 61 has an inclined surface portion 71 that is gradually inclined upward in side view. The base end 61 also has an inclined surface portion 72 that protrudes rearward and is inclined upward more sharply than the surface portion 71 in side view.

[0035] The intermediate portion 63 is formed in a plate shape. The intermediate portion 63 has a substantially flat top portion 73 that is continuous with the inclined surface portion 71, and a flat portion 74 that is continuous with the inclined surface portion 72.

[0036] The bearing portion 62 is formed in a substantially ring shape. The bearing portion 62 has a flat portion 75 continuing to a top portion 73, an inclined surface portion 76 continuing to the flat portion 74 and inclining downward, and an arc portion 77 having one end continuing to the flat portion 75 and the other end continuing to the inclined surface portion 76. The distance between an imaginary horizontal line including the top portion 73 and an imaginary horizontal line including the bottom end of the arc portion 77 is defined as a height H2 of the bearing portion 62. The height H1 of the bearing portion 91 and the height H2 of the bearing portion 62 are the same height.

[0037] 5(b), in a state where the connecting piece 6 and the connecting portion 9 are connected and the front section 3 is not flipped up, the height H2 of the connecting piece 6 and the height H1 of the connecting portion 9 are the same, that is, the height H. At this time, the axis of the shaft portion 93, which serves as the rotation axis of the front section 3, is located on the rear side of the frame main body 2 and in a position that protrudes slightly upward from the top of the frame main body 2.

[0038] Furthermore, the intermediate portion 63 of the connecting piece 6 is located above the top portion of the frame main body 2, and is connected to the connecting portion 9 across the top portion of the frame main body 2. The flat portion 74 faces the top portion of the frame main body 2. The inclined surface portion 72 is inclined downwardly below the top portion of the frame main body 2. Because of this configuration, the intermediate portion 63 is formed so that the height H2 does not become large while ensuring a thickness necessary to support the front portion 3.

[0039] Fig. 6 is a diagram showing the state in which the front part 3 of the flip-up eyeglasses 1 is flipped up. (a) is a perspective view from the front, and (b) is a partially enlarged right side view. Note that the temple 10 is omitted in Fig. 6(a).

[0040] 6(b), when the front part 3 is flipped up, the connecting piece 6 stands vertically and the front part 3 is held approximately horizontal. The shaft part 93 is provided on the rear side of the frame main body 2 and at a position that projects slightly upward from the top part of the frame main body 2, so that the distance H3 between the top part of the frame main body 2 and the lens 4 of the front part 3 can be made longer.

[0041] In this embodiment, the front bar 7 is formed in a substantially straight line shape in a plan view, and the shaft portion 93 is positioned on the rear side of the frame body 2 and at a position that protrudes slightly upward from the top of the frame body 2, thereby making it possible to lengthen the jump-up distance H3 of the lens 4 without complicating the shape of the front bar 7. This makes it possible to prevent the front portion 3 from entering the user's field of vision.

[0042] Furthermore, the thickness dimension of the intermediate portion 63 is the thickness necessary to support the front portion 3, while the heights H2 and H1 are formed to be the same dimension. Therefore, when the flip-up eyeglasses 1 are viewed from the front with the front portion 3 not flipped up, the height H, which is the vertical dimension of the connecting piece 6 and connecting portion 9, which are the hinges of the front portion 3, can be made small, and the connecting piece 6 and connecting portion 9 can be prevented from being noticeable.

[0043] <Flip-up Glasses 100> Fig. 7 is a diagram showing flip-up glasses 100 according to another embodiment of the present invention. (a) is a perspective view showing the flip-up glasses 100 in a state where the front part 3 is not flipped up, and (b) is a perspective view showing the flip-up glasses 100 in a state where the front part 3 is flipped up. Note that the temple parts 10 are omitted in Fig. 7.

[0044] In this embodiment, the frame body 2 is also provided with a frame-side lens 40. That is, a flip-up type eyeglasses 100 having a structure called a compound type will be described. In order to avoid duplication of explanation, the same reference numerals will be used to designate the same structural parts as those in the above-mentioned embodiment, and the explanation will be omitted.

[0045] The flip-up eyeglasses 100 have a lower frame 7d that is provided below the side bar 7a and forms a frame body, a lower frame 7e that is provided below the side bar 7b and forms a frame body, and frame-side lenses 40. The side bar 7a and the lower frame 7d, and the side bar 7b and the lower frame 7e are connected by end pieces 8, respectively, to form a frame body that holds the frame-side lenses 40.

[0046] In the flip-up eyeglasses 100, the axis 93 is positioned on the rear side of the frame body 2 and at a position that protrudes slightly upward from the top of the frame body 2, thereby making it possible to lengthen the flip-up distance H3 of the lens 4 without complicating the shape of the front bar 7. This makes it possible to prevent the front part 3 from entering the field of view of the user.

[0047] Furthermore, the thickness dimension of the intermediate portion 63 is the thickness necessary to support the front portion 3, while the heights H2 and H1 are formed to be the same dimension. Therefore, when the flip-up eyeglasses 1 are viewed from the front with the front portion 3 not flipped up, the height H, which is the vertical dimension of the connecting piece 6 and connecting portion 9, which are the hinges of the front portion 3, can be made small, and the connecting piece 6 and connecting portion 9 can be prevented from being noticeable.
