Description

Technical Field

[0001] The present invention relates to a spectacle wearing position changer that can be hung up and down while wearing spectacles.

Background Art

[0002] Conventionally, in order to see distant or nearby objects, a presbyopic glasses sliding device has been devised that can be easily moved up and down while wearing presbyopic glasses (see, for example, Patent Document 1). For example, the presbyopic glasses sliding device described in Patent Document 1 includes a clip for attaching a main body to the presbyopic glasses and a square bar having a rubber nose presser device at its tip. According to this sliding device, by sliding the nose presser device in the vertical direction while the presbyopic glasses are being worn, the wearing position of the presbyopic glasses can be changed from the normal position (the position where the pads of the presbyopic glasses touch the nose) where the user wearing the presbyopic glasses views objects through the presbyopic glasses to the retracted position (the position where the pads of the presbyopic glasses do not touch the nose) where the user views objects with the naked eye without wearing the presbyopic glasses.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, with reference to the drawings, a spectacle wearing position changing tool according to a preferred embodiment of the present invention will be described. The spectacle wearing position changing tool according to the present invention is a device for changing the wearing position of glasses in the vertical direction while the user is wearing the glasses.

[0025] FIG. 1 is an external perspective view of the spectacle wearing position changer 10 according to the first embodiment of the present invention. FIG. 2 is a view showing a state in which the spectacle wearing position changer 10 is attached to the glasses G. The spectacle wearing position changer 10 includes a bridge mounting portion 11 that is mounted on the bridge G1 of the glasses G, and a bridge support portion 12 that extends downward from the bridge mounting portion 11, and is characterized in that the bridge mounting portion 11 and the bridge support portion 12 are rotatably connected.

[0026] In the embodiment illustrated in FIG. 1, the bridge mounting portion 11 and the bridge support portion 12 are connected via a flexible adhesive tape 13. The adhesive tape 13 is adhered to the front surfaces of the bridge mounting portion 11 and the bridge support portion 12. With such a configuration, for example, as shown in FIGS. 3(a) and (b), the bridge support portion 12 is rotatable in the front-rear direction about the lower end portion of the bridge mounting portion 11.

[0027] In this specification, when referring to "front and rear", it is based on the user wearing the glasses G. That is, "front" or "forward" means the front direction as seen from the user. Also, "rear" or "rearward" means the rear direction as seen from the user, and "back surface" means the surface on the side facing the user.

[0028] The bridge mounting portion 11 is a member integrally formed of an elastically deformable synthetic resin material. The bridge mounting portion 11 has, for example, as shown in FIG. 1, a groove portion 111 for inserting the bridge G1 of the glasses G, and a constricted portion 112 for preventing the inserted bridge G1 from coming out and holding it. For this purpose, the constricted portion 112 has a shape bent like a "く" character toward the inside of the groove portion 111.

[0029] Note that the bridge mounting portion 11 is not limited to that shown in FIG. 1, and may be, for example, a movable clip that sandwiches the bridge of the glasses G.

[0030] The bridge support portion 12 is also a member integrally formed of an elastically deformable synthetic resin material, similar to the bridge mounting portion 11. For example, as shown in FIG. 1, the bridge support portion 12 is an elongated plate-like body, and its tip portion 121 is a nose contact portion 121 that is curved rearward in an arc shape.

[0031] In addition, the tip portion (nose contact portion) 121 of the bridge support portion 12 may have anti-slip structures 121´, 121´´, 121´´´. For example, a large number of grooves 121´ (tread pattern) can be engraved on the tip portion (nose contact portion) 121 of the bridge support portion 12 (FIG. 4), or a large number of unevenness can be formed (embossing) (FIG. 4). Also, the entire nose contact portion 121 can be formed of a material with a high coefficient of friction (such as silicone rubber, etc.), or a surface treatment can be performed to make the nose contact portion 121 a rough surface 121´´ so as to be difficult to slip (FIG. 5). Further, in order to increase the contact area with the nose as much as possible, an arc-shaped concave portion 121´´´ along the shape of the nose may be formed in the nose contact portion 121 (FIG. 6).

[0032] As described above, in the present embodiment, the bridge support portion 12 is rotatably connected to the bridge mounting portion 11. On the other hand, it is preferable that the glasses wearing position changing tool 10 has a rotation restricting portion 16 that restricts the bridge support portion 12 that rotates in the user side direction (rearward) at a predetermined position. Specifically, the rotation restricting portion 16 is formed as a short and inclined plate-like body that bends from the lower portion of the bridge mounting portion 11 toward the user side, as shown in FIG. 1 for example. In this aspect, when the bridge support portion 12 is rotated rearward, the bridge support portion 12 abuts against the rotation restricting portion 16 in an inclined manner at the rotation restricting position, thereby restricting further rotation of the bridge support portion 12.

[0033] In the present embodiment, as shown in FIG. 1 for example, the short plate-like rotation restricting portions 16 arranged opposite to each other and the narrow portion 112 of the bridge mounting portion 11 are separated by a predetermined distance and the lower part is open, thereby forming a bridge guide path 17 for easily guiding the bridge G1 of the glasses G into the groove portion 111 of the bridge mounting portion 11.

[0034] Next, taking the spectacle wearing position changer 10 according to the present embodiment as a representative example, its usage method will be briefly described. Note that the spectacle wearing position changers of other embodiments and modified examples described later also have the same functions as the present embodiment and are used in the same manner. Furthermore, the spectacle wearing position changers of any embodiment can be used for various spectacles G regardless of whether they are for presbyopia or myopia.

[0035] FIGS. 7 to 9 are diagrams for explaining the usage method of the spectacle wearing position changer 10. Here, FIG. 7 illustrates a state in the normal position where the spectacles G are lowered to a position where the pad G2 of the spectacles G touches the nose in order to see through the spectacles G, FIG. 8 illustrates a state in the intermediate position where the spectacles G are slightly lifted from the normal position, and FIG. 9 illustrates a state where the spectacles G are in the retracted position from the intermediate position in order to see without using the spectacles G.

[0036] As described above, the spectacle wearing position changer 10 is attached to the bridge G1 of the spectacles G by attaching the bridge mounting portion 11. As shown in FIG. 7, the user can lower the spectacles G to the normal position and see by rotating the tip portion 121 of the bridge support portion 12 forward to a free state. In this state, as shown in FIG. 8, the user slightly lifts the spectacles G from the normal position and rotates the tip portion 121 of the bridge support portion 12 backward so that the tip portion 121 of the bridge support portion 12 once faces directly downward to an intermediate position state. Subsequently, as shown in FIG. 9, while pressing the tip portion 121 against the nose, the bridge support portion 12 is rotated backward (toward the user, the front side) so that the base end portion 123 of the bridge support portion 12 abuts against the rotation restricting portion 16 in an inclined manner, whereby the bridge support portion 12 is locked.

[0037] In this state, the bridge support portion 12 is fixed to the upper part of the nose by the frictional force acting between the tip portion 121 of the bridge support portion 12 and the nose, and the wearing position of the glasses G can be easily changed to a retracted position higher than the above-mentioned normal position. (As other operation methods, there are also those shown below. That is, following the state shown in FIG. 8, as shown in FIG. 9, the bridge support portion 12 is rotated backward (toward the user, toward the front side), and the base end portion 123 of the bridge support portion 12 is brought into inclined contact with the rotation restricting portion 16 to lock the bridge support portion 12. In this state, the glasses G that had been lifted are lowered, and the tip portion 121 is applied to the upper part of the nose (FIG. 9). As a result, the frictional force due to the self-weight of the glasses G and the glasses wearing position changing tool 10 acts, and the tip portion 121 is fixed to the upper part of the nose, so the wearing position of the glasses G can be easily changed to a retracted position higher than the above-mentioned normal position).

[0038] As described above, the glasses wearing position changing tool 10 according to the present embodiment is easy to wear on the glasses G and is also easy to move the glasses G up and down. In addition, since it has a compact and simplified configuration, it is possible to prevent blocking the user's field of view during wearing. Also, weight reduction can reduce the burden on the user's nose.

[0039] The bridge support portion 12 of the glasses wearing position changing tool 10 may be formed of a material that plastically deforms. For example, as shown in FIGS. 10(a) and 10(b), by bending and deforming the bridge support portion 12 at an appropriate position, the distance between the tip portion 121 of the bridge support portion 12 and the bridge mounting portion 11 can be arbitrarily adjusted. For example, as shown in FIG. 10(a), since the distance between the tip portion 121 of the bridge support portion 12 and the bridge mounting portion 11 can be arbitrarily adjusted, it is possible to accommodate people with large faces to small faces regardless of face size. Also, for example, as shown in FIG. 10(b), since the bridge support portion 12 can be bent and rotated backward (toward the user, toward the front side) at an appropriate position, the retracted position of the glasses G can be freely set each time. In this case, it is preferable that one or a plurality of wires 122 are embedded along the longitudinal direction of the bridge support portion 12.

[0040] Further, as shown in FIGS. 11(a) and 11(b) for example, the spectacle wearing position changing device 10 may have a holding portion 19 that regulates and holds a bridge support portion 12 that rotates forward as viewed from the user at a predetermined position. Specifically, the holding portion 19 can be two hook-and-loop fasteners provided on the front surface of the adhesive tape 13. In this case, the bridge support portion 12 can be held by folding it onto the bridge mounting portion 11. Therefore, the spectacle wearing position changing device 10 can be stored compactly, and also, when using the spectacles G, it can be prevented from obstructing the user's field of view.

[0041] Furthermore, as in the spectacle wearing position changing device 10a shown in FIG. 12 for example, the spectacle wearing position changing device 10 has a sheet metal two-claw clamp 18 formed on the front surface of a clip 11 as the bridge mounting portion 11. The two-claw clamp 18 functions as a holding portion that regulates the bridge support portion 12 at a predetermined rotation position and holds it in that position. According to this aspect, since the bridge support portion 12 can be held by the two-claw clamp 18 in a state where it is folded onto the clip 11, the spectacle wearing position changing device 10a can be stored compactly, and also, when using the spectacles G, it can be prevented from obstructing the user's field of view. In the spectacle wearing position changing device 10a of FIG. 12, a main body fixing portion 15 is provided on the front surface of the clip 11, and an adhesive tape 13 is stretched between the main body fixing portion 15 and the bridge support portion 12. The two-claw clamp 18 is provided on the front surface of the clip 11 via the main body fixing portion 15.

[0042] A spectacle wearing position changing device 10b which is a modification of this embodiment is shown in FIG. 13. In this spectacle wearing position changing device 10b, the bridge mounting portion 11 and the bridge support portion 12 are integrally connected via a thin portion 14. In this spectacle wearing position changing device 10b, the bridge mounting portion 11 and the bridge support portion 12 are rotatably connected via the thin portion 14. In this aspect, since the bridge mounting portion 11 and the bridge support portion 12 can be integrally formed, the number of parts can be reduced and the cost can be suppressed.

[0043] Another modification example of the present embodiment, the spectacle wearing position changer 10c, is shown in FIGS. 14(a) and 14(b). In this spectacle wearing position changer 10c, the bridge mounting portion 11 and the bridge support portion 12 are rotatably connected via a hinge portion 15. According to this aspect, as shown in FIG. 15, the bridge mounting portion 11 and the bridge support portion 12 can be compactly stored, and when using the spectacles G, it is possible to prevent obstructing the user's field of view.

[0044] In the spectacle wearing position changers 10c and 10d in the embodiments of FIGS. 14 and 15, the hinge portion 15 was provided at the lower end portion of the bridge mounting portion 11. However, as shown in the spectacle wearing position changers 10e and 10f in the embodiments of FIGS. 16 and 17, for example, the hinge portion 15 may be provided at the front central portion of the bridge mounting portion 11. By doing so, the spectacle wearing position changers 10e and 10f can be made smaller and lighter. Further, the spectacle wearing position changers 10e and 10f may be configured such that a hinge shaft 151 is provided at the front central portion of the bridge mounting portion 11, and a bearing 152 with a part cut out is provided at the base end portion 123 of the bridge support portion 12, and the bridge support portion 12 is detachably attached to the bridge mounting portion 11.

[0045] Next, the spectacle wearing position changer 20 according to the second embodiment of the present invention will be described. The spectacle wearing position changer 10 of the first embodiment is configured such that the bridge support portion 12 is connected on the front side of the bridge mounting portion 11. In contrast, the spectacle wearing position changer 20 according to the second embodiment is configured such that the bridge support portion 22 is connected on the rear side (back side) of the bridge mounting portion (clip) 21.

[0046] Here, FIG. 18 is an external perspective view of the spectacle wearing position changer 20 according to the second embodiment. This spectacle wearing position changer 20 includes a movable clip 21 as a bridge mounting portion that sandwiches the bridge G2 of the spectacles G, and a bridge support portion 22 that is rotatably connected via a flexible adhesive tape 23 on the back surface of the clip 21.

[0047] More specifically, a main body fixing portion 25 is provided on the back surface of the clip 21 (i.e., the surface facing the user's face), and an adhesive tape 23 is stretched between the main body fixing portion 25 and the bridge support portion 22. Further, a nose rest portion 221 made of, for example, silicon rubber with a high coefficient of friction is provided at the tip end portion 221 of the bridge support portion 22.

[0048] Also, a rotation restricting portion 26 is formed to restrict the rotation of the bridge support portion 22 that rotates forward as viewed from the user at a predetermined position. The rotation restricting portion 26 is composed of a bent portion 251 formed at the lower end of the main body fixing portion 25 and a bent portion 222 provided at the upper end of the bridge support portion 22.

[0049] The user can firmly hold the glasses G in the normal position by rotating the bridge support portion 22 forward (toward the back surface of the clip) as viewed from the user, bending it, and pressing the nose rest portion 221 near the root of the nose. On the other hand, the user can easily change the wearing position of the glasses G to a retracted position higher than the above normal position by rotating the bridge support portion 22 in the opposite direction to the front rotation restricting position (the position where the bent portion 251 and the bent portion 222 come into contact), locking the bridge support portion 22, and pressing the tip end portion 221 against the upper part of the nose. (In other words, the user can firmly hold the glasses G in the normal position by rotating the bridge support portion 22 forward (toward the back surface of the clip) as viewed from the user and storing the nose rest portion 221 near the rear (back) part of the bridge mounting portion 21. On the other hand, the user slightly lifts the glasses G from the normal position, rotates the bridge support portion 22 in the opposite direction to the front rotation restricting position (the position where the bent portion 251 and the bent portion 222 come into contact), locks the bridge support portion 22, lowers the lifted glasses G, and presses the tip end portion 221 against the upper part of the nose. As a result, a frictional force acts in the same mechanism as in the first embodiment, and the tip end portion 121 is fixed to the upper part of the nose, so the wearing position of the glasses G can be easily changed to a retracted position higher than the above normal position).

[0050] According to the spectacle wearing position changer 20 according to the second embodiment described above, by using the movable clip 21 as the bridge mounting portion 21, it becomes easy to attach and detach the spectacles G. Further, since it has a compact and simplified configuration, it does not obstruct the user's field of view when worn, and the weight reduction can also reduce the burden on the user's nose. In addition, since it can be folded compactly, it is excellent in storage property.

[0051] Note that the present invention is of course capable of various modified implementations and application implementations within the scope of the invention described in the claims without being limited to the above-described embodiments. That is, for example, the spectacle wearing position changers 10 and 20 can be implemented in any form in which all or part of them are separated or all or part of them are integrated, and both the separated form and the integrated form are included in the claims.
