Detailed Description

Hereinafter, a facewear and a fastener for a facewear according to an embodiment of the present invention will be described in detail with reference to the drawings. The embodiments described below are specific preferred examples for carrying out the present invention, and therefore, although various technical limitations are imposed, the present invention is not limited to the embodiments unless the limitations are specifically expressed in the following description.

Description of the preferred embodiments

A facial wearing article according to an embodiment of the present invention will be described with reference to fig. 1 and 2. Fig. 1 is a perspective view showing a eyewear according to an embodiment. Fig. 2 is a top view showing the face wear of fig. 1.

As shown in fig. 1 and 2, the eyewear according to the embodiment includes a eyewear body 1, a pair of head bands 2 made of an elastic material, and a fastener 3 for connecting the pair of head bands 2 to each other.

The present invention can be applied to various types of eyewear as long as the eyewear body is provided with band attachment portions through which the headband can be inserted at both ends thereof. For example, the present invention can be applied to various types of eyewear such as ski goggles, motorcycle goggles, dust-proof goggles, safety goggles, head-mounted display goggles, sunglasses, dust-proof glasses, and vision correction glasses.

As shown in fig. 1, in the embodiment, the attachment body 1 includes a pair of lens portions 1a, a pair of lens frame portions 1b, a pair of gasket portions 1c, and a nose connector 1 d. Further, band attaching portions 4 through which the headband 2 is inserted are formed at both ends of the wearing article main body 1. A pair of headband 2 are attached to the two band attaching portions 4, respectively, and the pair of headband 2 are connected to each other by a fixing buckle 3. The holder buckle 3 has a plug 10 and a receptacle 20.

Hereinafter, the headband 2 will be described with reference to fig. 3. Fig. 3 is a perspective view showing a headband for a eyewear according to an embodiment.

As shown in fig. 3, the headband 2 is a band-shaped member having a band proximal end portion 30 and a band distal end portion 40, and has a loop portion 50, a first insertion hole 60, a second insertion hole 70, a stopper portion 80, a thick plate portion 90, an overlapping portion 100, and a coupled portion 110 between the band proximal end portion 30 and the band distal end portion 40. As a material of the headband 2, various elastic materials such as thermoplastic elastomer, silicone rubber, synthetic rubber, and the like can be used. The tape base end portion 30 corresponds to the second base end portion in the claims, and the tape tip end portion 40 corresponds to the second tip end portion in the claims.

The ring portion 50 is positioned closer to the band proximal end portion 30 than the center in the longitudinal direction in the headband 2 as shown in fig. 3, and engages with the band attachment portion 4 as shown in fig. 1 and 2, thereby connecting the headband 2 to the wearing article main body 1. When attaching the headband 2 to the band attachment portion 4, the headband 2 is inserted with the band end portion 40 through the band attachment portion 4 until reaching the loop portion 50. Further, the belt distal end portion 40 is inserted through the belt mounting portion 4 from the inside to the outside of the wearing body 1.

As shown in fig. 3, the first insertion hole 60 is formed closer to the base end portion 30 than the ring portion 50. The band terminal portion 40 of the headband 2 is insertable into the first insertion hole 60, and as shown in fig. 1 and 2, the band terminal portion 40 is inserted into the band attaching portion 4 and then inserted into the first insertion hole 60. The headband 2 is inserted through the first insertion hole 60 until reaching the boundary position of the ring portion 50, whereby the ring portion 50 is formed in a ring shape.

As shown in fig. 3, the second insertion hole 70 is formed closer to the tape base end portion 30 than the first insertion hole 60. The band end portion 40 of the headband 2 is inserted into the second insertion hole 70, and as shown in fig. 1 and 2, the band end portion 40 is inserted into the second insertion hole 70 after being inserted into the first insertion hole 60. The headband 2 is inserted through the second insertion hole 70 to a position where an overlapping portion 100 described later overlaps a thick plate portion 90 described later in a close contact state.

As shown in fig. 3, the stopper 80 is provided to protrude from, for example, the inner surface 50a of the ring 50. As shown in fig. 2, the stopper 80 is engaged with the belt mounting portion 4 so as to prevent the loop portion 50 from passing completely through the belt mounting portion 4. In the embodiment, the stopper 80 is formed in a protruding shape that is long in the width direction of the headband 2.

As shown in fig. 3, the thick plate portion 90 is formed between the first insertion hole 60 and the second insertion hole 70, and has a larger plate thickness than the surrounding portions.

As shown in fig. 3, the overlapping portion 100 is located closer to the belt terminal portion 40 than the loop portion 50. As shown in fig. 2, the overlapping portion 100 overlaps with a portion of the headband 2 between the first insertion hole 60 and the second insertion hole 70. In the embodiment, as shown in fig. 3, the overlapping portion 100 is formed wider than the surrounding portion.

The connected portion 110 is located closer to the band end portion 40 than the center in the longitudinal direction in the headband 2, and is connected to the buckle 3 so as to adjust the length of the headband 2. The length adjustment mechanism for the headband 2 is described below. Further, the coupled portion 110 is formed wider as a whole than a portion other than the coupled portion 110 in the headband 2.

As described above with reference to fig. 1 to 3, according to the eyewear of the embodiment, the ring portion 50 connects the headband 2 to the eyewear body 1, and thus the headband 2 can be attached to the eyewear body 1 only by providing the band attachment portions 4 through which the headband 2 can be inserted at both ends of the eyewear body 1, and the present invention can be easily applied to various eyewear.

Further, according to the eyewear of the embodiment, since the headband 2 has two insertion holes, i.e., the first insertion hole 60 and the second insertion hole 70, the headband 2 near the ring portion 50 can be easily shaped into a linearly extending shape, and the eyewear can be easily worn and removed, and the wearing feeling can be improved.

Further, according to the eyewear of the embodiment, the stopper portion 80 is provided in the ring portion 50, so that when the headband 2 is attached to the band attachment portion 4, the headband 2 can be prevented from being inserted into the band attachment portion 4 beyond the ring portion 50. Therefore, the headband 2 can be coupled to the wearing article main body 1 at a fixed position in the headband 2, and the headband 2 can be easily attached to the band attachment section 4.

Further, according to the eyewear of the embodiment, by forming the thick plate portion 90 between the first insertion hole 60 and the second insertion hole 70, the portion where the headband 2 overlaps in two layers in the vicinity of the ring portion 50 can be easily arranged in a linearly extending shape, the eyewear can be further easily worn and removed, and the wearing feeling can be further improved.

Further, according to the eyewear of the embodiment, since the overlap portion 100 is formed to be wide, the headband 2 can increase the area of the portion abutting against the temporal edge of the user, and the contact pressure can be reduced, thereby further improving the wearing feeling.

Further, according to the eyewear mounting device of the embodiment, since the coupled portion 110 is formed to be wide as a whole, when the headband 2 and the holder buckle 3 are coupled by the frictional force between the surfaces, a larger frictional force can be exerted, and the headband 2 and the holder buckle 3 can be coupled with sufficient strength.

On the other hand, by making the width of the portion of the headband 2 other than the portion 110 to be connected smaller than the portion 110 to be connected, the headband 2 can be stretched and contracted with a smaller force when the facewear is worn and removed, the range of the length over which the headband 2 can exert a sufficient elastic force necessary for fixing the facewear can be widened, and the length adjustment of the headband 2 can be facilitated. Therefore, it becomes easy to fix the visor to the head of the user with a sufficient elastic force required, and it is possible to further facilitate the attachment and detachment of the visor.

Next, the fixing clip 3 will be described with reference to fig. 4 to 7. Fig. 4 is a perspective view showing the attachment buckle for a eyewear according to the embodiment. Fig. 5 is a front view showing the holder buckle for a facial wearing part of fig. 4. Fig. 6 is an exploded perspective view of the attachment buckle for a eyewear of fig. 4. Fig. 7 is a plan view showing the operation of the attachment buckle for a eyewear of fig. 4.

As shown in fig. 4 and 5, the plug 10 of the holder buckle 3 includes a locking piece 12 having a circular projection 11, a platen 13, a support 14, a receiving portion 15, a first coupling portion 16, and a rotation restricting portion 17.

The receptacle 20 of the holder buckle 3 includes a to-be-locked portion 22 formed with a circular recess 21, a platen contact portion 23, a peripheral wall portion 24, a second coupling portion 25, and a to-be-regulated portion 26. The recess 21 is a through hole penetrating the plate-shaped engaged portion 22 in the embodiment, and is fitted to the projection 11 to pivotally support the plug 10. That is, the plug 10 is coupled to the receptacle 20 so as to be rotatable within a predetermined angular range by fitting the convex portion 11 to the concave portion 21.

In the embodiment, the holder 3 is made of a hard plastic such as polycarbonate, nylon, polyester, and ABS resin. Since the holder 3 is made of hard plastic, when the plug 10 and the socket 20 are coupled, the fitting between the convex portion 11 and the concave portion 21 can be clearly perceived according to sound and touch, and the wearing and removal of the eyewear can be further facilitated.

The projection 11 of the plug 10 has a circular shape in plan view as viewed in the projecting direction X1. As shown in fig. 5, the projecting direction X1 of the projection 11 is a direction intersecting the insertion direction X3 when the plug 10 is inserted into the receptacle 20. The convex portion 11 is inclined in the top surface so that the protruding height becomes smaller toward the insertion direction X3.

The top surface of the projection 11 is inclined so that the projection height decreases in the insertion direction X3, and thus the projection 11 and the recess 21 can be smoothly fitted to each other when the plug 10 is inserted into the receptacle 20. On the other hand, the projection 11 has a larger projection height in the removal direction X4 when the plug 10 is removed from the receptacle 20. Therefore, the plug 10 can be locked to the receptacle 20 with sufficient strength by fitting the convex portion 11 and the concave portion 21.

As shown in fig. 5 and 6, the locking piece 12 of the plug 10 is oval in plan view, and has a base end portion 12a as a first base end portion, an intermediate portion 12b, and a tip end portion 12c as a first tip end portion. The base end portion 12a is a portion connected to the support portion 14. The intermediate portion 12b is a portion between the proximal end portion 12a and the distal end portion 12c, and is provided with a protruding portion 11 protruding therefrom. The distal end portion 12c is a free end portion of the locking piece 12.

The base plate 13 of the plug 10 is disposed in a direction X2 opposite to the protruding direction X1 of the projection 11 with respect to the locking piece 12. In the embodiment, the platen portion 13 is a circular plate-shaped member disposed in the opposite direction X2 with respect to the locking piece 12 with a predetermined gap from the locking piece 12.

As shown in fig. 4 and 6, the support portion 14 of the plug 10 elastically supports the locking piece 12 on the base plate portion 13 in a fitting state where the convex portion 11 and the concave portion 21 are fitted. That is, in the embodiment, the locking piece 12 is cantilevered by the support portion 14 at the base end portion 12 a.

The receiving portion 15 of the plug 10 is formed at a position closer to the distal end portion 12c than the projecting portion 11 of the locking piece 12, and receives a pressing operation for pressing the locking piece 12 in the opposite direction X2, that is, a pressing operation for releasing the fitting state of the projecting portion 11 and the recessed portion 21. In the embodiment, the receiving portion 15 is formed on the surface of the distal end portion 12c of the locking piece 12 on the side of the projecting direction X1. The receiving portion 15 has a plurality of protrusions 15a for preventing slipping. As described above, the clasp 3 according to the embodiment is of the front release type in which the fitted state is released by pressing the locking piece 12 in the direction X2 opposite to the projecting direction X1.

As shown in fig. 4 and 5, the first connecting portion 16 of the plug 10 is formed integrally with the base plate portion 13, and connects the headband 2 to the plug 10. The first link 16 includes a plurality of

rod members

16a, 16b, and 16c as a length adjustment mechanism of the headband 2.

The plurality of

rod members

16a, 16b, and 16c are arranged in parallel with each other at predetermined intervals in the first connecting portion 16, and frictionally engage with the headband 2. That is, the band end portion 40 of the headband 2 is inserted through the plurality of

rod members

16a, 16b, and 16c through a passage shown by, for example, a curved line a with an arrow in fig. 5, whereby the coupled portion 110 of the headband 2 is frictionally engaged with the first coupling portion 16, and the plug 10 and the headband 2 are coupled so that the length of the headband 2 can be adjusted freely.

The rotation restricting portions 17 of the plug 10 are provided so as to protrude from both side portions of the platform portion 13 as shown in fig. 5 and 6, and abut against the receptacle 20 so as to restrict a rotation range of the plug 10 with respect to the receptacle 20 as shown in fig. 7. In the embodiment, the plug 10 is rotated about a central axis passing through the center of the circular projection 11, and the right and left maximum rotational positions L2, L3 are restricted by the rotation restricting portion 17.

In the embodiment, the maximum pivot angles α 1 and α 2 between the left and right maximum pivot positions L2 and L3 and the neutral position L1 of the plug 10 are equal. The maximum rotation angles α 1 and α 2 may be acute angles, and are preferably angles of 45 ° or less, more preferably angles of 20 ° or less, and further preferably angles of 5 ° to 10 °.

The engaged portion 22 of the receptacle 20 abuts against the locking piece 12 of the plug 10 when the plug 10 is inserted into the receptacle 20. The platen contact portion 23 of the socket 20 contacts the platen portion 13 of the plug 10 when the plug 10 is inserted into the socket 20. The peripheral wall 24 of the receptacle 20 faces the support portion 14 so as to surround the support portion 14 of the plug 10 when the plug 10 is inserted into the receptacle 20.

The second coupling portion 25 of the socket 20 couples the socket 20 and the headband 2, and has a length adjustment mechanism that adjusts the length of the headband 2. As shown in fig. 4 and 5, the second coupling portion 25 is formed integrally with the platen contact portion 23 and includes a plurality of

rod members

25a, 25b, and 25 c. The restricted portion 26 abuts against the rotation restricting portion 17 so as to restrict the rotation range of the plug 10 with respect to the receptacle 20.

As described above with reference to fig. 1 to 2 and 4 to 7, according to the facemount and the retaining buckle for the facemount of the present embodiment, the plug 10 and the receptacle 20 are coupled by fitting the circular convex portion 11 and the circular concave portion 12. Therefore, even if the orientation of plug 10 and socket 20 is not aligned but slightly inclined, plug 10 can be inserted into socket 20, and the coupling operation of plug 10 and socket 20 at the occiput portion becomes easy.

Further, according to the eyewear and the clasp for eyewear of the present embodiment, since the locking piece 12 has the receiving portion 15 at the position closer to the distal end portion 12c than the protruding portion 11, the fitting state between the protruding portion 11 and the recessed portion 21 can be released with a smaller force by the principle of leverage, and the eyewear can be further easily attached and detached. Further, the fitting state of the convex portion 11 and the concave portion 21 can be released with a smaller force, and thus the fitting state of the convex portion 11 and the concave portion 21 can be easily released even if the supporting force with which the supporting portion 14 elastically supports the locking piece 12 is increased. Therefore, the support portion 14 can be designed to exhibit a larger support force, and the bonding strength between the plug 10 and the receptacle 20 can be further increased.

The fitting state between the convex portion 11 and the concave portion 21 can be released by pressing the convex portion 11 with a finger through the concave portion 21, for example. However, if the diameter of the concave portion 21 is small, the finger cannot be pushed against the convex portion 11 through the concave portion 21. According to the embodiment, since the locking piece 12 has the receiving portion 15, even when the diameter of the concave portion 21 is small and the convex portion 11 cannot be pressed by a finger, the receiving portion 15 can be pressed to release the fitting state of the convex portion 11 and the concave portion 21. Therefore, even if the recess 21 is designed to have a small diameter, the holder buckle 3 can be easily miniaturized without any problem.

Further, according to the facepiece and the fastener for the facepiece of the present embodiment, the maximum rotation angles α 1 and α 2 are in the above-described ranges, and thus, the headband 2 can be effectively prevented from shifting when the facepiece is worn. For example, if the headband 2 is hung on the occiput of the user at a position above the eyes in order to prevent the detachment and displacement of the headgear and the water leakage in the headgear body 1 at the start of diving or swimming, a downward force is applied to both ends of the holder buckle 3. In the case of a general hook-type locking buckle or a side-release-type locking buckle, the plug and the socket are fixed in a state of being aligned in a straight line, and thus the locking buckle 3 is easily displaced downward. According to the retainer clasp 3 of the embodiment, the relative angle between the plug 10 and the socket 20 is changed according to the position of the retainer clasp 3 at the occiput portion, thereby effectively preventing the displacement of the retainer clasp 3 and effectively preventing the dropping and the displacement of the face wearing part.

Further, for example, when the user moves the wearing piece main body 1 to the forehead while wearing the face wearing piece, the wearing piece main body 1 can be smoothly moved to the forehead by the relative rotation of the plug 10 and the socket 20.

On the other hand, the maximum rotation angles α 1 and α 2 are in the above-described ranges, so that the relative rotation angle between the plug 10 and the receptacle 20 can be prevented from becoming excessively large, the fitting state between the convex portion 11 and the concave portion 21 can be prevented from being easily released, and the eyewear can be stably fixed to the head. That is, if the top surface of the projection 11 is inclined so that the projection height decreases toward X3, the fitting state between the projection 11 and the recess 21 is easily released if the plug 10 is turned at a large angle with respect to the receptacle 20. By setting the maximum rotation angles α 1, α 2 in the above ranges, for example, even when the attachment body 1 is moved to the forehead, the relative angle between the plug 10 and the receptacle 20 can be prevented from becoming excessively large, and the fitting state between the convex portion 11 and the concave portion 21 can be prevented from being easily released.

Next, a facewear according to another embodiment will be described with reference to fig. 8. Fig. 8 is a perspective view showing a eyewear according to another embodiment of the present invention.

As shown in fig. 8, the eyewear according to the present embodiment is sunglasses, and includes a spectacle body 1A as an eyewear body. The eyeglass body 1A includes a pair of colored lens portions 1A, a lens frame portion 1b, and a nose pad 1 e. In the embodiment, the pair of lens portions 1a are integrally formed and formed of a single curved resin plate or glass plate. The pair of lens portions 1a may be formed separately or may be connected to each other by a nose connector or the like, not shown.

The eyeglass body 1A has a band attachment portion 4 at each end through which the headband 2 is inserted. The user inserts the headband 2 through the band attachment portion 4, and attaches the headband 2 to the eyeglass body 1A. The structure of the present embodiment other than the eyeglass body 1A is the same as that of the embodiment shown in fig. 1 to 7.

As described above with reference to fig. 8, the eyewear of the present embodiment is sunglasses, and the eyeglass body 1A has the band attachment portions 4 at both ends through which the headband 2 is inserted.
