Patent Documents

[0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2015-191231 Patent Document 2: Japanese Utility Model Registration No. 3204319 Patent Document 3: Japanese Unexamined Patent Application Publication No. 2013-97102 Summary of the Invention

[0004] However, in the above-described hinge-less eye-wear device, only the groove portion penetrating in the inner and outer directions of the footrest provided at the front end of the footrest in the rear region of one temple is clamped from above on the front region portion of the other temple. Structurally, when an external force acting upward is applied to the clamping portion between the front end of the footrest and the temple, the clamping may be easily disengaged, resulting in the release of the folded state of the temple. In addition, in these hinge-less eye-wear devices, a decoration and a ring joint structure are provided in the front region portion of the other temple, presenting a special design in appearance. For users who prefer a simple hinge-less eye-wear device, there are design limitations instead.

[0005] The present invention has been completed in view of the above aspects, and when clamping and folding a pair of temples of a hinge-less eye-wear device, it is possible to suppress a situation where one temple accidentally disengages from the other temple. In particular, it is possible to suppress a situation where the clamping is easily disengaged and the folded state of the temple is released when an external force acting upward or downward is applied to the clamping portion. In addition, an object of the present invention is to provide a hinge-less eye-wear device in which the clamping structure between the temples is not easily noticeable and has a simple and natural shape and a delicate design.

[0006] One technical solution of the present invention relates to an eye-wearing device having a front frame and a pair of temple arms that are connected to the front frame in a hinge-free manner without a hinge structure having a rotation axis and are flexible. Each temple arm has a front region on the front frame side and a rear region on the rear end side opposite to the front frame side. The front region has a protrusion protruding in at least one of the inner or outer directions of the temple arm, and the rear region has a groove portion and a recess. The groove portion is recessed from one surface in the up-down direction of the temple arm toward the other surface and penetrates the temple arm in the inner-outer direction. The recess is disposed on the outer side surface of the temple arm, is recessed in the inner direction of the temple arm, and communicates with the groove portion. The pair of temple arms are configured such that the groove portion in the rear region of one temple arm is inserted into a portion closer to the front frame side than the protrusion in the front region of the other temple arm, and further slid along the front region toward the protrusion side, and the protrusion of the other temple arm is received in the recess of one temple arm.

[0007] According to this technical solution, since the protrusion of the other temple arm is received in the recess of one temple arm, when folding the temple arms, it is possible to suppress the accidental detachment of the temple arms from each other.

[0008] In the above technical solution, the recess may also have a top surface, a bottom surface, and an inner surface, and an opening communicating with the groove portion is formed between the top surface and the bottom surface.

[0009] In the above technical solution, the recess may also have a side surface on the opposite side of the opening.

[0010] In the above technical solution, the recess may be configured such that the protrusion can move within the recess.

[0011] In the above technical solution, the recess may be configured to fit with the protrusion.

[0012] In the above technical solution, the protrusion may also have a triangular prism shape that has a triangular shape when looking down at the temple arm.

[0013] In the above technical solution, the protrusion may also protrude only in the inner direction of the temple arm and have a length in the up-down direction that is the same as or shorter than the length of the temple arm in the up-down direction.

[0014] According to the present invention, when the pair of temple arms of the hinge-free eye-wearing device are engaged with each other and folded, it is possible to suppress the accidental detachment of one temple arm from the other temple arm. In particular, it is possible to suppress the case where the engagement is easily disengaged when an external force is applied upward or downward to the engagement portion, resulting in the release of the folded state of the temple arms. Furthermore, it is possible to provide a hinge-free eye-wearing device in which the engagement structure between the temple arms is not easily noticeable, having a simple and natural shape and a delicate design.

Detailed Description of the Invention

[0016] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described. Figure 1 A perspective view showing an example of the structure of the eye-wear device 1. Figure 2 A top view showing an example of the structure of the eye-wear device 1. Figure 3 A side view showing an example of the structure of the eye-wear device 1. It should be noted that in this specification, the front and rear of the eye-wear device 1 are the same as the front and rear of the wearer's head when wearing the eye-wear device 1. The front frame 10 side when viewed from the temple 11 described later is defined as the front, and the temple 11 side when viewed from the front frame 10 is defined as the rear. The up and down of the eye-wear device 1 are the same as the up and down of the wearer's head when wearing the eye-wear device 1. In addition, the side of the temple 11 facing the wearer's head is defined as the inner side, and the side of the temple 11 opposite to the wearer's head is defined as the outer side. The direction perpendicular to the front-rear direction of the front frame 10 and horizontal is defined as the left-right direction.

[0017] As Figure 1 and Figure 2 shown, in one embodiment, the eye-wear device 1 includes a front frame 10 and a pair of temples 11.

[0018] In one embodiment, the front frame 10 is configured to support a pair of lenses 20 side by side in the left - right direction Y. The front frame 10 has a pair of lens holding portions 30 for holding the left and right lenses 20, and a connecting portion (center beam) 31 that connects the pair of lens holding portions 30 to each other. The connecting portion 31 is located at the center of the front frame 10 in the left - right direction Y, and the front frame 10 is configured to be left - right symmetric with the connecting portion 31 as the center. The front frame 10 further includes a nose pad 40 that abuts against the wearer's nose.

[0019] As Figures 1 to 3 shown, the temple 11 is configured to hang on the wearer's ear. Each temple 11 is connected to the lens holding portion 30 of the front frame 10. Each temple 11 is connected to the front frame 10 in a hinge - less manner without a hinge structure having a rotation axis.

[0020] The temple 11 has flexibility. The temple 11 can be made of metal or resin. The temple 11 has an elongated shape that is longer in the front - rear direction X. The temple 11 can also have a square cross - sectional shape with thickness in the up - down direction Z and the in - out direction R. The dimension of the temple 11 in the up - down direction Z can be larger than the dimension in the in - out direction R. The temple 11 can have a curved shape that gradually bends inward as it approaches the rear end.

[0021] The temple 11 has a front region 50 on the side of the front frame 10 and a rear region 51 on the rear end side opposite to the front frame 10 side.

[0022] The front region 50 forms a hinge - less folding portion without a hinge structure having a rotation axis between it and the front frame 10. The front region 50 has a protrusion 60 that protrudes at least in either the inner direction R1 or the outer direction R2 of the temple 11. In one embodiment, the protrusion 60 only protrudes in the inner direction R1 of the temple 11.

[0023] As Figure 4 shown, the protrusion 60 has a generally triangular - prism shape when viewed from above the temple 11. The protrusion 60 has an inner surface 60a that smoothly protrudes inward from the temple body 11a. That is, the inner surface 60a of the protrusion 60 is smoothly and continuously connected to the front - rear inner surface (the inner surface of the temple body 11a) of the temple 11 without a step difference.

[0024] The protrusion 60 has a length in the up - down direction Z that is the same as or shorter than that of the temple body 11a. Therefore, as Figure 3 shown, when the eyewear 1 is observed from the outside (in Figure 3 , from the left side when viewed by the wearer), the protrusion 60 can be hidden behind the temple body 11a and cannot be seen.

[0025] As Figure 3 and Figure 5 shown, the rear region 51 has a groove portion 80 and a recess portion 81. The groove portion 80 is recessed from one surface in the vertical direction Z of the temple 11 toward the other surface, and penetrates the temple 11 in the inner and outer direction R. In one embodiment, the groove portion 80 is recessed from the lower surface toward the upper surface. The groove portion 80 is configured to be inserted into the front region 50 of the temple 11 from above.

[0026] The recess portion 81 is disposed on the outer side surface of the temple 11 and is recessed toward the inner direction R1. The recess portion 81 communicates with the groove portion 80. The recess portion 81 is disposed adjacent to the front frame side (front side) of the groove portion 80 in the temple 11. The recess portion 81 is configured to be able to accommodate the protrusion portion 60.

[0027] The recess portion 81 has a top surface 100, a bottom surface 101, and an inner surface 102. An opening OP communicating with the groove portion 80 is formed between the top surface 100 and the bottom surface 101 of the recess portion 81. The recess portion 81 has a side surface 103 on the opposite side of the opening OP.

[0028] The recess portion 81 is configured such that the protrusion portion 60 can move within the recess portion 81 in a state where the protrusion portion 60 is accommodated in the recess portion 81. The recess portion 81 may have a size larger than that of the protrusion portion 60 in the vertical direction Z and the front-rear direction X. The recess portion 81 may have a size larger than that of the protrusion portion 60 in the inner and outer direction R. The recess portion 81 and the protrusion portion 60 may be configured such that the protrusion portion 60 is completely accommodated in the recess portion 81, or may be configured such that a part of the protrusion portion 60 is accommodated in the recess portion 81. It should be noted that the temple 11 may have a footrest portion made of resin or rubber in the rear region 51, and the groove portion 80 and the recess portion 81 may be provided in the footrest portion.

[0029] The pair of temples 11 is configured such that by inserting the groove portion 80 of the rear region 51 in one temple 11 into a portion of the front region 50 of the other temple 11 that is closer to the front frame 10 than the protrusion portion 60 and further sliding it along the front region 50 toward the protrusion portion 60 side, the protrusion portion 60 of the other temple 11 is accommodated in the recess portion 81 of one temple 11. That is, the eyewear 1 can perform the following folding operation of the temples 11.

[0030] When folding the temples 11 of the eyewear 1, first, as Figure 6 shown, the first temple 11-1 is bent significantly inward. Then, as Figure 7 shown, the groove portion 80 of the rear region 51 in the first temple 11-1 is inserted into a portion of the front region 50 of the second temple 11-2 that is closer to the front frame 10 than the protrusion portion 60. At this time, due to the flexibility of the first temple 11-1, a restoring force (elastic force) in the outer direction R2 acts on the first temple 11-1. Then, asFigure 8 As shown, the rear area 51 of the first temple 11-1 is slid along the front area 50 of the second temple 11-2 toward the protrusion 60 side, and the protrusion 60 of the second temple 11-2 is received in the recess 81 of the first temple 11-1. At this time, due to the restoring force of the first temple 11-1, the protrusion 60 of the second temple 11-2 abuts against the inner surface 102 of the recess 81 of the first temple 11-1. In addition, the movement of the protrusion 60 of the second temple 11-2 in the vertical direction Z is restricted by the top surface 100 and the bottom surface 101 of the recess 81 of the first temple 11-1. Thereby, the rear area 51 of the first temple 11-1 is fixed to the front area 50 of the second temple 11-2.

[0031] Next, for the second temple 11-2, similarly, the second temple 11-2 is bent significantly toward the inside, and the groove 80 of the rear area 51 in the second temple 11-2 is inserted into a portion of the front area 50 of the first temple 11-1 that is closer to the front frame 10 than the protrusion 60. Next, the rear area 51 of the second temple 11-2 is slid along the front area 50 of the first temple 11-1 toward the protrusion 60 side, and the protrusion 60 of the first temple 11-1 is received in the recess 81 of the second temple 11-2. Due to the restoring force of the second temple 11-2, the protrusion 60 of the first temple 11-1 abuts against the inner surface 102 of the recess 81 of the second temple 11-2. In addition, the movement of the protrusion 60 of the first temple 11-1 in the vertical direction Z is restricted by the top surface 100 and the bottom surface 101 of the recess 81 of the second temple 11-2. Thereby, the rear area 51 of the second temple 11-2 is fixed to the front area 50 of the first temple 11-1. In this way, as Figure 9 shown, the temples 11 (temple 11-1 and temple 11-2) of the eye-wearing device 1 are folded.

[0032] When opening the temples 11 of the eye-wearing device 1, as Figure 7 shown, the groove 80 of the rear area 51 in the first temple 11-1 is slid along the front area 50 of the second temple 11-2 toward the front frame 10 side (inner direction R1), and the protrusion 60 of the second temple 11-2 is taken out from the recess 81 of the first temple 11-1. Next, the groove 80 of the first temple 11-1 is moved upward relative to the front area 50 of the second temple 11-2, and the first temple 11-1 is removed from the second temple 11-2. Thereby, the fixation between the rear area 51 of the first temple 11-1 and the front area 50 of the second temple 11-2 is released.

[0033] For the second temple 11-2, similarly, slide the groove portion 80 of the rear region 51 in the second temple 11-2 along the front region 50 of the first temple 11-1 toward the front frame 10 side, and remove the protrusion 60 of the first temple 11-1 from the recess 81 of the second temple 11-2. Then, move the groove portion 80 of the second temple 11-2 upward relative to the front region 50 of the first temple 11-1, and remove the second temple 11-2 from the first temple 11-1. Thereby, the engagement between the rear region 51 of the second temple 11-2 and the front region 50 of the first temple 11-1 is released.

[0034] According to the present embodiment, in the hinge-less eye-wear device 1, the front region 50 of the temple 11 has a protrusion 60 protruding toward the inner direction R1 of the temple 11, the rear region 51 has a groove portion 80 and a recess 81. The groove portion 80 is recessed from the lower surface in the vertical direction Z of the temple 11 toward the upper surface and penetrates the temple 11 in the inner-outer direction R. The recess 81 is disposed on the outer side surface of the temple 11, is recessed toward the inner direction R1 of the temple 11, and communicates with the front frame side (front side) of the groove portion 80. And, the pair of temples 11 are configured such that by inserting the groove portion 80 of the rear region 51 in one temple 11 into a portion closer to the front frame 10 side than the protrusion 60 in the front region 50 of the other temple 11 and further sliding it along the front region 50 toward the protrusion 60 side, the protrusion 60 of the other temple 11 is received in the recess 81 of one temple 11. Thereby, when the pair of temples 11 of the eye-wear device 1 are engaged with each other and folded, it is possible to suppress a situation where one temple 11 accidentally detaches from the other temple 11. In particular, it is possible to suppress a situation where when an upward external force acts on the engaged portion, the engagement is easily released and the folded state of the temples is released. In addition, since the temples 11 are engaged with each other by receiving the protrusion 60 in the recess 81, the engagement mechanism is simple and the appearance of the engaged state is also simplified. Therefore, it is also possible to realize an eye-wear device having a simple and natural shape and a delicate design in which the engagement structure between the temples is not easily noticeable.

[0035] The recess 81 has a top surface 100, a bottom surface 101, and an inner surface 102, and an opening OP communicating with the groove portion 80 is formed between the top surface 100 and the bottom surface 101. Thus, the movement of the protrusion 60 is restricted by the three surfaces of the recess 81, that is, the top surface 100, the bottom surface 101, and the inner surface 102. In particular, the inner surface 102 of the recess 81 of one temple 11 is pressed by the restoring force of one temple 11 and abuts against the protrusion 60 of the other temple 11, whereby the engagement becomes reliable and accidental detachment can be further suppressed.

[0036] The recess 81 has a side surface 103 on the side opposite to the opening OP. Thus, the movement of the protrusion 60 is restricted by the four surfaces of the recess 81, namely, the top surface 100, the bottom surface 101, the inner surface 102, and the side surface 103, and the accidental detachment of one temple 11 from the other temple 11 can be further suppressed.

[0037] The recess 81 is configured such that the protrusion 60 can move within the recess 81. Thus, it is easy to accommodate the protrusion 60 in the recess 81. In addition, since the protrusion 60 is allowed to move within the recess 81, in other words, there is a gap in the locked state, even if an external force is applied to the locked portion and it is slightly deformed, the detachment of the temples 11 from each other can be suppressed.

[0038] The protrusion 60 has a triangular prism shape that is triangular when looking down at the temple 11. Thus, when the recess 81 is moved from the front frame 10 side toward the protrusion 60 side, the protrusion 60 can be smoothly locked.

[0039] The protrusion 60 protrudes only in the inner direction R1 of the temple 11 and has a length in the vertical direction Z that is the same as or shorter than the length of the temple 11 in the vertical direction Z. Thus, the protrusion 60 does not protrude outward or in the vertical direction of the temple 11, and therefore, when operating or wearing the eye-wear 1, the situation where the protrusion 60 collides with or catches on surrounding components can be suppressed. In addition, since the protrusion 60 is not easily visible from the outside, as the hinge-less eye-wear 1 having a simple and natural shape, the appearance can be improved.

[0040] In the above-described embodiment, the recess 81 may be configured to be fitted with the protrusion 60. For example, as Figure 10 shown, the protrusion 60 may have a spherical protrusion shape that protrudes in the vertical direction Z and the inner-outer direction R of the temple body 11a in the front region 50 of the temple 11 (11-2). The recess 81 may have a hemispherical recess shape that is fitted with the protrusion 60 of the other temple 11-2 in the rear region 51 of the temple 11 (11-1). The recess 81 and the protrusion 60 may have the same radius. The recess 81 may be formed to surround the groove portion 80 on the outer side surface of the temple 11 (11-1). The protrusion 60 and the recess 81 can be fitted by pressing the recess 81 into the protrusion 60. In this case, the detachment of the protrusion 60 from the recess 81 can be suppressed.

[0041] The eye-wear 1 is not limited to the structure described in the above embodiment. The structures, shapes, sizes, etc. of the front frame 10 and the temples 11 are not limited to the content of the above embodiment. For the recess 81 and the protrusion 60, as long as the protrusion 60 can be accommodated in the recess 81, other shapes (for example, replacing the above triangular prism shape with a quadrangular prism shape, etc.) and sizes can be adopted.

[0042] In one of the above embodiments, the protrusion 60 protrudes only in the inner direction R1 of the temple 11, but it may also protrude only in the outer direction R2. In this case, the recess 81 of the temple 11 may be arranged adjacent to the side (rear side) of the groove 80 in the temple 11 opposite to the front frame. In addition, the protrusion 60 may protrude in both the inner direction R1 and the outer direction R2 of the temple 11. Although the groove 80 is a structure recessed from the lower surface of the temple 11 toward the upper surface, it may also be a structure recessed from the upper surface of the temple 11 toward the lower surface. In this case, the groove 80 of one temple 11 can be inserted into the front region 50 of the other temple 11 from below, and then slid along the front region 50 toward the protrusion 60 side, so that the protrusion 60 is received in the recess 81. In this case, even if a downward external force is applied to the locking portion, it is possible to suppress the locking from easily coming off and causing the folded state of the temple to be released.
