Description

[Technical field]

[0001] The present invention relates to an eyeglass frame. [Background technology]

[0002] Conventionally, eyeglass frames are composed of a front and temples, and since the width of the face of each wearer varies from person to person, the temples are generally often worn in a bent state.

[0003] Patent Document 1 shows an innovation in which cushion parts are molded using a 3D printer on the inside surfaces of the temples so that the glasses do not press hard against the sides of the face when worn.

[0004] Patent Document 2 shows an idea in which eyeglass frames are made with a 3D printer using a thermoplastic resin material with a glass transition temperature of 30°C to 50°C, and when in use, the frame is heated to 30°C to 50°C to soften parts of the material and deform to fit the shape of the wearer's face.

[0005] Furthermore, Patent Document 3 shows a technique in which the front portion of the temple is made of a coil spring, making the temple more likely to bend at the front portion when worn.

[0006] Furthermore, Patent Document 4 shows a device for improving springiness by providing a plurality of notched grooves in the front portion of the temple and alternating the notched directions. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 7039538 [Patent Document 2] Utility Model Registration No. 3214406 [Patent Document 3] Japanese Patent Application Publication No. 02-214508 [Patent Document 4] JP 2003-315744 A Summary of the Invention [Problem to be solved by the invention]

[0008] However, the device shown in Patent Document 1, in which the cushion part is formed on the temple by a 3D printer using the above-mentioned synthetic resin material as a molding material, does not go so far as to improve the flexibility of the temple. Also, the device shown in Patent Document 2 is for creating an eyeglass frame that fits the shape of the wearer's head, but does not disclose a technology for imparting flexibility to the temple itself.

[0009] The device shown in Patent Document 3 requires the manufacture of a coil spring that matches the thickness of the temple, which has the disadvantage of increasing manufacturing costs, and the device shown in Patent Document 4 also requires the processing of forming the cutout grooves, which is time-consuming and similarly increases manufacturing costs.

[0010] In view of the above circumstances, the present invention has an object to provide an eyeglass frame that is comfortable to wear by improving the flexibility of the temples without subjecting them to machining. [Means for solving the problem]

[0011] The present invention has been made in consideration of the above problems, and provides a temple having a flexible portion at a front side portion of the temple that is elastically deformable in a direction perpendicular to the temple length direction, The flexible portion is A row of inner parts in which a plurality of L-shaped inner parts are nested along the inner side of the temple of the eyeglasses; A row of outer parts in which multiple L-shaped outer parts are nested along the outer side of the temple of the glasses; Equipped with a pointed end portion of an outer part of the row of outer parts is connected to a pointed end portion of an inner part of the row of inner parts; The above problem is solved by providing an eyeglass frame characterized in that the opening side end of an inner part in the inner part row is connected to the opening side end of an outer part that is positioned next to the outer part in the part arrangement order in the outer part row.

[0012] In the present invention, it is advantageous that the outer part and the inner part connected to each other at their pointed end portions each undergo bending deformation with the position of the connected pointed end portion as the base end.

[0013] Furthermore, in the present invention, it is preferable that the entire flexible portion is integrally molded from a synthetic resin material. Effect of the Invention

[0014] According to the present invention, the inner parts of the inner part row are formed in a L-shape, and the outer parts of the outer part row are also formed in a L-shape, the pointed end of the outer part of the outer part row is connected to the pointed end of the inner part of the inner part row, and the open end of the inner part of the inner part row is connected to the open end of the outer part that is next in order to the outer part in the part arrangement order of the outer part row.

[0015] In this manner, with regard to the mutual connection between the inner parts and the outer parts, one outer part is connected to an inner part on the inside, and that inner part is connected to the next outer part in the arrangement order of the one outer part, so that the inner parts and outer parts are connected alternately.

[0016] The multiple inner parts in the row of inner parts are arranged in a nested manner, and similarly, the multiple outer parts in the row of outer parts are arranged in a nested manner, so that when an external force such as bending is applied to the flexible portion, the applied external force is distributed to the multiple inner parts and outer parts.

[0017] Furthermore, the distributed forces cause the gap between the connected inner and outer parts to open or close.

[0018] Therefore, when the eyeglass frames are worn, an external force is applied to the flexible portion when the temple is bent or twisted, causing the flexible portion to bend, making the temple more comfortable to wear.

[0019] Furthermore, according to the present invention, the outer part and the inner part connected to each other at their pointed end portions each undergo bending deformation with the position of the connected pointed end portion as the base end.

[0020] In this way, each of the many inner parts and outer parts undergoes bending deformation independently, with the connected pointed end position as the base end, so that each inner part and outer part undergoes a small bending deformation, and a highly flexible bending state is created in the flexible section as a whole, without generating large resistance in each of the inner parts and outer parts.

[0021] Furthermore, according to the present invention, the entire flexible portion is integrally molded from synthetic resin material, and therefore can be manufactured using a 3D printer. Furthermore, 3D printers that use synthetic resin materials allow for a high degree of freedom in the shape of the molded object, making it possible to improve the design of the flexible parts. [Brief description of the drawings]

[Diagram 2] 10 is an explanatory diagram showing a flexible portion of the temple as viewed from the inside of the temple. FIG. [Diagram 3] 10 is an explanatory diagram showing a flexible portion of the temple as viewed from the outer side of the temple. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Next, the present invention will be described in detail based on the embodiment shown in the drawings. In the drawings, reference numeral 1 denotes an eyeglass frame, which comprises a front 2 and temples 4 connected to the left and right end portions of the front 2 via hinge structures 3 so as to be foldable toward the back of the front 2.

[0024] (Front, Temple) The front 2 is made of a synthetic resin material. Similarly, the temples 4 are also made of a synthetic resin material.

[0025] (Flexible part) The temple 4 has a flexible portion 5 on the front 2 side, and is arranged so that this flexible portion 5 is deflected when an external force is applied to bend or twist the temple 4 so as to open it to the side of the eyeglasses.

[0026] This flexible portion 5 is elastically deformable in a direction perpendicular to the longitudinal direction of the temple 4, and bending of this flexible portion 5 enables the temple 4 to bend or twist in the left-right and up-down directions of the glasses.

[0027] As shown in FIG. 2, the flexible portion 5 includes a row of inner parts 6 positioned along the inner side of the temple 4 of the eyeglasses, and a row of outer parts 7 positioned along the outer side of the temple 4 of the eyeglasses. The inner part row 6 and the outer part row 7 are connected together as described below, and are integrated into one piece. The inner part row 6 and the outer part row 7 are not separate from each other.

[0028] (Inner parts row) As shown in FIG. 2, the inner part row 6 includes a plurality of L-shaped inner parts 8 arranged along the inner side of the temple 4 of the eyeglasses.

[0029] The inner part 8 in the front position in the part arrangement (for example, on the side of the hinge structure part 3 in this embodiment) is nested so that the pointed end portion 8a of the next inner part 8 in the part arrangement is located in the open portion of the inner part 8 in the front position in the part arrangement (for example, on the side of the hinge structure part 3 in this embodiment).

[0030] The inner parts 8 adjacent to each other in the arrangement order are molded so as to be arranged so as not to contact each other, and the pointed end portion 8a is also not in contact with the inner part 8 in the front position.

[0031] (Outer parts row) As shown in FIG. 3, the outer part row 7 also includes a plurality of L-shaped outer parts 9 arranged along the inner side of the temple 4 of the eyeglasses.

[0032] As in the case of the inner part row 6, in the outer part row 7, the outer parts are nested so that the pointed end 9a of the next outer part 9 in sequence relative to the outer part 9 in the previous position in the part order is located in the open portion.

[0033] Furthermore, the inner parts 9 adjacent to each other in the arrangement order are molded so as to be arranged so as not to contact each other, and the pointed end portion 9a is also not in contact with the inner part 9 in the front position.

[0034] (Connection of inner and outer part rows) The inner part row 6 and the outer part row 7 are connected, and as shown in Figures 2 and 3, the pointed end portion 9a of the outer part 9 of the outer part row 7 is connected together with the pointed end portion 8a of the inner part 8 of the inner part row 6 at a position overlapping the outer part 9 in the thickness direction of the temple 4 via the pointed side connecting portion 10.

[0035] In addition, the open end 8b of the inner part 8 in the inner part row 6 is connected to the open end 9b of the outer part 9 that is positioned next to the outer part 9 in the part arrangement order in the outer part row 7. Each of the inner parts 8 has two opening side ends 8b, and each of the outer parts 8 has two opening side ends 9b. The opening side ends 8b of the inner parts 8 and the opening side ends 9b of the outer parts 9 are connected together via opening side connecting portions 11 on the upper and lower edges of the flexible portion 5.

[0036] The flexible portion 5 is molded by a 3D printer using a synthetic resin material as a molding material. The flexible portion 5 is molded by the 3D printer, and the portion of the temple 4 rearward from the flexible portion 5 is molded separately, and the separately molded portion is combined with the flexible portion 5 to create the temple 4, which is then connected to the front 2. Of course, the portion of the temple 4 rearward from the flexible portion 5 can also be manufactured by a 3D printer.

[0037] The flexible portion 5 is molded from a synthetic resin material, and each of the outer part 9 and the inner part 8 connected by the pointed side connecting portion 10 is capable of flexural deformation at the position of the connected pointed end, i.e., with the pointed side connecting portion 10 as the base end.

[0038] For example, the outer parts 9 of the outer part row 7 and the inner parts 8 of the inner part row 6 are positioned so as to overlap in the thickness direction of the flexible portion 5 and are connected by the pointed side connecting portion 10, and when an external force such as bending or twisting is applied to the flexible portion 5, the space between the outer parts 9 and the inner parts 8 connected by the pointed side connecting portion 10 opens or narrows, causing the flexible portion 5 to flex and deform.

[0039] The changes between the outer part 9 and the inner part 8 occur when the outer part 9 and the inner part 8 flex with the pointed connecting part 10 as the base end, opening or narrowing the space between the outer part 9 and the inner part 8. The outer part 9 and the inner part 8 are also configured to deform so as to rotate in different directions relative to each other in the height direction of the flexible part 5 with the pointed connecting part 10 as the base end.

[0040] In addition, the outer part 9 and the inner part 8 are configured so that the degree to which the L-shaped parts expand and contract can be changed.

[0041] In the illustrated embodiment, the part at the foremost position of the flexible portion 5 is an inner part 8, and a connecting ring 12 on the temple side of the hinge structure 3 is integrally formed at the tip of this foremost inner part 8. In addition, the part at the rearmost position of the flexible portion 5 is also an inner part 8, and the rear member of the temple 4 from the flexible portion 5 is continuous with this rearmost inner part 8.

[0042] 2 and 3, in order to make the configuration of the flexible portion 5 easier to understand, the front 2 is not shown. [Explanation of symbols]
