[Effect of Invention]

According to the present invention, among the glasses with detachable frames, the glasses and the frame can be provided which can prevent the frame from falling off accidentally.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the embodiments described below are examples at all, and it is not intended to exclude the application of various changes or techniques not explicitly described below. That is, the present invention can be implemented with various changes within a range not departing from the gist. In addition, in the description of the following drawings, the same or similar symbols are attached to the same or similar parts and displayed. Drawings are schematic and do not necessarily correspond to actual dimensions or proportions. Sometimes the drawings also include parts with different dimensional relationships or ratios.

[implementation form] ＜Glasses＞ 1 to 3 are diagrams illustrating the state of the glasses 100 according to the embodiment, for example, with the frame 140 removed. Fig. 1 is a plan view showing an example viewed from above the glasses 100 of the embodiment. Fig. 2 is a front view showing an example viewed from the front of the glasses 100 of the embodiment. Fig. 3 is a side view showing an example viewed from the left side of the glasses 100 of the embodiment.

In the following description, for the sake of convenience, the length direction of the mirror frame 140 or the lower frame 146 shown in FIGS. 1-3 is referred to as "left-right direction". Also, when the glasses 100 are worn, the left side (right side in FIG. 1 ) viewed from the user is referred to as "left side", and the right side viewed from the user (left side in Fig. 1 ) is referred to as "right side". Furthermore, let the short side direction of the mirror frame 140 or the lower frame 146 be referred to as the "up and down direction", and the thickness direction of the mirror frame 140 or the lower frame 146 be referred to as the "front-rear direction".

The eyeglasses 100 to which this embodiment is applied are symmetrically formed around the brow (nose bridge) 142 (collectively referred to as 142A and 142B). Therefore, in the following description, regarding the left-right symmetrical configuration, the left and right sides are not distinguished, and only the configuration on either side of the drawings is described with symbols. Moreover, the nose bridge 142 of the glasses 100 includes the nose bridge 142A of the lower frame 146 or the nose bridge 142B of the frame.

As shown in FIGS. 1-3 , the frame 140 can be removed from the frame 120 of the glasses 100 . The example shown in FIG. 1 is an example of the frame 120 when the mirror frame 140 is removed from above. The glasses 100 shown in FIG. 1 are synonymous with the frame 120 and mainly have a lower frame 146 , a pair of temples 180 and a pair of foot covers 160 . The glasses 100 may also be referred to as the frame 120 in a state where the frame 140 is removed, and may also be collectively referred to as the glasses 100 in a state where the frame 140 is attached.

The frame 120 has, for example, a lower frame 146, a pair of mirror feet 180 rotatably connected to the two ends of the left and right sides of the lower frame 146, a pair of foot covers 160 mounted on the rear side of the pair of mirror feet 180, and a pair of mirror legs 160 formed on the lower frame. A pair of pile head 147 of each end portion of 146 and a pair of first hinge part that are installed on the back side of a pair of pile head 147.

The lower frame 146 has, for example, a nose bridge 142A, a pair of nose pads 144 mounted on the left and right sides of the back of the nose bridge 142A, and a pair of lower frame parts 146R, 146L formed on the left and right ends of the nose bridge 142A. In addition, the nose bridge 142A may be formed of the same member as the pair of lower frame portions 146R and 146L, or may be formed of a different member.

The nose bridge 142A is a part connecting the left part 146L and the right part 146R of the pair of lower frame parts. In addition, the nose bridge 142A is, for example, a curved plate-shaped member formed of resin or the like.

The nose pad 144 supports the frame 120 by sandwiching the user's nose from both sides, and maintains the height of the frame 120 relative to the user's eyes. Moreover, the nose pad 144 is any one of the nose pad independent type which has a resin pad part (nose pad type) and a metal support part, for example. In addition, the posture of the frame 120 relative to the user's eyes and nose (for example, the distance between corneal vertices) can be finely adjusted by deforming the cushion part and the supporting part.

In addition, the nose pad 144 can also be detachably formed from the lower frame 146 . Moreover, the nose pad 144 can also be formed on the mirror frame 140 instead of the lower frame 146 . Furthermore, the nose pad 144 formed on the mirror frame 140 can be detachably formed. For the detachable structure, well-known techniques such as a fitting structure can also be used, for example.

The lower frame 146 holds the mirror frame 140 by being mounted with the mirror frame 140 . In addition, the lower frame 146 is, for example, a semicircular member formed along the shape of various mirror frames 140, and is formed of resin or the like.

A first hinge portion is formed on the stud 147 provided at the outer end of the lower frame 146 . In addition, the stake head 147 is, for example, a curved plate-shaped member formed of resin or the like.

The first hinge part functions as an example of the connecting part between the stud 147 and the mirror foot 180, and is combined with the second hinge part having a plate shape formed on the mirror foot 180 side, whereby the mirror foot 180 is relative to the lower frame 146. Rotatably linked. That is, the first hinge part and the second hinge part constitute the hinge 148 .

The mirror feet 180 together with the foot cover 160 press the user's side head and sandwich this part. In addition, the foot cover 160 is in contact with the top and back of the user's ear to prevent the eyeglasses 100 from falling. In addition, the foot cover 130 is not necessarily required for the glasses 100 .

Also, the temple 180 is a member that is bent to fit the side head. Furthermore, the temples 180 are rotatably connected within a range from a folded position having the smallest angle between the lower frame 146 to an open position having the largest angle between the lower frame 146 .

Next, the spectacle frame 140 that can be mounted on the lower frame 146 will be described. The mirror frame 140 can also hold a pair of lenses. The mirror frame 140 is, for example, formed in a plate shape extending in the left-right direction, and is curved so as to protrude forward along the user's face. Also, the mirror frame 140 has a nose bridge 142B at the central portion in the X direction. Also, if the mirror frame 140 has a mounting structure described later, mirror frames of various sizes, shapes, colors, materials, etc. can be used.

＜Installation structure＞ In addition to FIGS. 1 to 3 , the attachment structure of the mirror frame 140 and the lower frame 146 will be described using FIGS. 4 and 5 . Fig. 4 is a front view showing an example of the eyeglasses 100 when the eyeglass frame 140 of the embodiment is mounted. FIG. 5 is a perspective view of an example of glasses 100 viewed from the lower left when the frame 140 of the embodiment is mounted.

In the example shown in FIGS. 1 to 5 , the lower frame frame 120 has at least two first mounting structures 200A on the nose bridge 142A side of the lower frame 146 . For example, at least one mounting structure 200A is formed on the right lower frame portion 146R, and at least one mounting structure 200A is formed on the left lower frame portion 146L.

For example, the first installation structure 200A is provided on the lower frame 146 on the side of the central position C1 than the central position C1 of the lower frame 146 in the X direction and the respective central positions CL1 , CL1 of the outer end portions EL1 , ER1 . As a specific example, the first mounting structure 200A is formed near the nose bridge 142A located near the central position C1.

The mirror frame 140 has at least two second attachment structures 200B. The at least two second installation structures 200B can be installed on the at least two first installation structures 200A on the side of the lower frame 146, and are arranged at the position of the mirror frame 140 corresponding to the positions of the at least two first installation structures 200A.

According to the above-mentioned structure, since the installation structure of the mirror frame 140 and the lower frame 146 can be provided at a position that is not easily affected by the deformation of the glasses 100 caused by opening and closing the temples 180, wearing the glasses 100, etc., when wearing the glasses 100, etc., the frame 140 is not easy to fall off. As a result, the user can stably use the eyeglasses 100 with the frame 140 attached thereto.

In addition, the first mounting structure 200A and the second mounting structure 200B may include any one of a specific fitting structure, a structure using a magnet, and a structure using a hook and loop. From the viewpoint of reducing the number of parts of the glasses 100 , a fitting structure that can be integrally formed with the frame 120 or the mirror frame 140 is preferable.

For example, a specific fitting structure uses a concavo-convex structure. In the example shown in FIGS. 1 to 5 , the first mounting structure 200A is formed with a concave portion (through hole) on the lower frame 146 side, and the second mounting structure 200B is formed with a convex portion on the mirror frame 140 side.

For example, in the examples shown in FIGS. 1 to 5 , the first mounting structure 200A that forms a concave portion is formed in the first region of the frame 146 under the nose of the user who is close to the glasses 100 . The second region of the mirror frame 140 forms the second mounting structure 200B of the convex portion. The mirror frame 140 is mounted on the lower frame 146 by fitting the convex portion of the second mounting structure 200B on the frame 140 side into the concave portion of the first mounting structure 200A on the lower frame 146 side. In addition, a convex portion may be provided on the lower frame 146 and a concave portion may be provided on the mirror frame 140 .

According to the above configuration, when the frame 140 is installed on the lower frame 146, the vicinity of the nose bridge 142A of the lower frame 146 is pressed inwardly (pressed with a force of F1), so that the nose bridge 142A is bent inwardly (for example, refer to FIG. 2 ). By fitting the second mounting structure 200B into the first mounting structure 200A bent inward by the force of F1, the mirror frame 140 is mounted on the lower frame 146 (for example, refer to FIG. 4 ).

In addition, in the example shown in FIG. 4 , the reaction force F2 for partial restoration of the bent lower frame 146 is generated, and the coupling force between the first mounting structure 200A and the second mounting structure 200B is strengthened by this reaction force F2.

Thereby, when opening and closing the temples 180 or when wearing the glasses 100, etc., the frame 140 is installed around the non-deformable nose bridge 142, so that the frame 140 can be prevented from accidentally falling off. In other words, since the frame 140 is installed at a position that is not easily affected by the extension of the temple 180, the glasses 100 can be stably installed even when the frame 140 is installed.

Furthermore, since the user's nose is located at the nose bridge 142 when wearing the glasses 100, the nose bridge 142 is not easy to bend inwardly, on the contrary, it is easy to receive force in the direction that the bridge of the nose expands outward. Therefore, the first mounting structure 200A and the second mounting structure 200B are less likely to fall off.

In addition, the first mounting structure 200A may be provided at least two for each of the left and right lower frame portions 146L, 146R (for example, in FIG. 3 ). The mounting structures may also be separated by more than a certain distance (eg, 0.5 cm). 2 and 4, during installation, the positions near the left and right lower frame parts 146L, 146R are bent in the X direction more than the positions near the nose bridge 142A, so the reaction force for restoration due to bending is larger than that of the left and right lower frame parts. The positions near 146L and 146R are stronger. Thereby, at least one 1st mounting structure 200A is preferably provided in the position near the left and right lower frame parts 146L, 146R. Thereby, the bonding force of the 1st installation structure 200A and the 2nd installation structure 200B becomes stronger.

Also, at least two first installation structures 200A and second installation structures 200B may be provided within a certain distance from the mirror frame 140 or the nose bridge 142 of the frame 120 (for example, refer to FIGS. 2 to 5 ). For example, within a specific distance means the distance from the central position C1 corresponding to the average length of the bridge of the user's nose.

Also, as mentioned above, the nose pad 144 that can be attached to and detached from the mirror frame 140 or the lower frame 146 may also be provided. The nose pad 144 can be any one of nose pad type or nose pad independent type. As for the attachment and detachment method, well-known methods such as fastening with screws or fitting of concavo-convex parts are preferable.

Thereby, the nose pad 144 can be selected by the user himself according to the shape and size of the user's nose. As a result, the glasses 100 can be customized according to the user's preferences and the like.

<YZ section of frame 140 and lower frame 146> Next, the shape of the YZ cross section of the mirror frame 140 and the lower frame 146 (lower frame portion 146R) will be described using FIGS. 6A and 6B . The YZ section shown in FIG. 6A and FIG. 6B shows the YZ section at the position A1 in FIG. 2 .

FIG. 6A is a diagram showing Example 1 of the YZ section of the mirror frame 140 and the lower frame 146 of the embodiment. In the example shown in FIG. 6A , the lower frame 146 has a step difference from the Y1 direction to the Y2 direction. For example, if the thickness of the lower frame 146 in the Z direction on the Y1 side is W1, and the thickness in the Z direction on the Y2 side is W2, then W1<W2.

At this time, the lower part of the mirror frame 140 is positioned on the upper surface S1 of the step (referred to as “step A”) of the lower frame 146 having a thickness W1. Moreover, the wall V1 formed by the step of the thickness W2 (referred to as "step B") and the step A of the thickness W1 restricts the movement of the lower part of the mirror frame 140 to the rear in the Y2 direction.

Here, in the eyeglasses 100 when the eyeglass frame 140 is attached, the lower frame of the eyeglass frame 140 is arranged on the surface S1 of the lower frame 146 , thereby forming a frame portion of the eyeglasses 100 . At this time, when viewing the glasses 100 from the front, the lower part of the frame 140 is located on the surface S1 of the step A where the thickness of the lower frame 146 is thinner, so as the lower frame of the glasses 100, the thickness in the Z direction can be reduced. As a result, the difference between the upper frame portion of the glasses 100 (the frame portion sandwiching the left and right upper sides of the nose bridge 142B of the frame 140) and the lower frame portion (the frame portion sandwiching the left and right sides of the nose bridge 142B of the frame 140) can be reduced. The sense of incongruity in the appearance caused by the difference in the thickness of the frame part + the thickness W1 of the step A in the Z direction, that is, the impression that the frame part is too thick when viewed from the front. Furthermore, the movement of the mirror frame 140 in the Y2 direction is restricted by the wall V1 in the direction from step A to step B, so that the positional deviation of the mirror frame 140 is not easy to occur. In addition, in the example shown in FIG. 6A, the step A is located in the Y1 direction, and the step B, which is thicker than the step A, is located in the Y2 direction, but even if the positional relationship is reversed, the same effect can be obtained. That is, the step B may be located in the Y1 direction, and the step A may be located in the Y2 direction. In this case, the movement of the mirror frame 140 in the Y1 direction is restricted by the wall V1.

FIG. 6B is a diagram showing Example 2 of the YZ cross section of the mirror frame 140 and the lower frame 146 (lower frame portion 146R) of the embodiment. In the example shown in FIG. 6B , the lower frame 146 has a concave portion on the Z1 direction (upper) surface, and the lower frame portion of the mirror frame 140 has a convex portion on the Z2 direction (lower) surface.

In the case of the above configuration, when the first installation structure 200A of the lower frame 146 and the second installation structure 200B of the mirror frame 140 are installed, the convex portion of the lower frame portion of the mirror frame 140 is fitted into the concave portion of the lower frame 146 . Thereby, the position deviation of the mirror frame 140 in the Y direction is limited, and the position deviation of the mirror frame 140 in the Y direction is not easy to occur. Alternatively, the concave portion may be formed on the mirror frame 140 and the convex portion may be formed on the lower frame 146 .

According to the example shown in FIG. 6A and FIG. 6B , the lower frame 146 may also have a concave portion or a stepped portion disposed in a specific area. Moreover, the mirror frame 140 can also be provided with a convex portion or a lower portion (end portion below) positioned at the concave portion or the stepped portion at a position corresponding to the concave portion or the stepped portion of the lower frame 146 .

Moreover, the specific area can also be set between the central position C1 of the lower frame 146 and each central position CL1, CR1. For example, a step or a recess may also be provided on a part of the lower part of the central side of the lower frame 146 . In this case, it may be formed such that the step or the recess gradually disappears as it approaches the outer side of the lower frame 146 .

Thereby, in the positioning mechanism of the mirror frame 140, when the mirror feet 180 are opened and closed, or when the mirror feet 180 are worn, etc., it is not easily affected by the deformation force applied to the pile head 147, and the mirror frame 140 is not easy to fall off. The glasses 100 are worn steadily.

＜Examples of changes in installation structure＞ Next, a modification example of the first mounting structure will be described using FIG. 7 . Fig. 7A is a side view showing another first installation structure 200A1 and nose bridge 142A of the embodiment. Fig. 7B is a perspective view showing another first installation structure 200A1 and nose bridge 142A of the embodiment. In the example shown in FIG. 7A and FIG. 7B , the first installation structure 200A1 protrudes upward from the upper surface around the nose bridge 142 of the lower frame 146 and has a convex portion with a certain length (for example, 3 cm, etc.) in the X direction. On the mirror frame 140, a second mounting structure (not shown) including a concave portion is provided at a position corresponding to the first mounting structure 200A1. In addition, a concave portion may be provided in the first mounting structure 200A, and a convex portion may be provided in the second mounting structure.

In this way, the mirror frame 140 can be installed in the nose bridge 142A part that is not easily affected by the opening and closing of the mirror feet 180. Moreover, the first installation structure and the second installation structure have a specific length in the X direction, thereby preventing the mirror frame 140 from facing each other. In the lower frame 146, it rotates on a plane (horizontal plane) including the X direction and the Y direction. According to this configuration, at least one first attachment structure 200A1 may be provided for the lower frame 146 . Also, as a structure for preventing rotation of the mirror frame 140 by one mounting structure 200A1, the shape of the first mounting structure 200A1 may be a shape other than a circle such as three sides or four sides in plan view. For example, in FIGS. 7A and 7B , the shape of the first mounting structure 200A1 is a quadrangular shape in which the X direction becomes the longitudinal direction in plan view.

＜Circulation form＞ For the above-mentioned glasses 100, the lower frame frame 120 can be circulated as the glasses 100, and even the mountable mirror frame 140 can be circulated alone, and can also be used as glasses with the lower frame frame 120 and the mountable mirror frame 140. 100 in circulation.

When the lower frame frame 120 is distributed as the glasses 100, the glasses 100 include: the lower frame frame 120; the lower frame 146 contained in the frame 120; and at least two first installation structures 200A, which can be installed on the frame 140. At least two first mounting structures 200A are provided on the lower frame 146 on the side closer to the central position C1 than the central position C1 of the lower frame 146 and the respective central positions CL1 and CR1 of the outer end portions EL1 and ER1 .

Also, when the mountable mirror frame 140 is circulated alone, the mirror frame 140 has: at least two second mounting structures 200B, which can be mounted on at least two first mounting structures 200A, and are installed on at least two first mounting structures 200A. The position of the mirror frame 140 corresponding to the position of the installation structure 200A, the at least two first installation structures 200A are arranged at the center position C1 of the lower frame 146 contained in the frame 120 of the glasses 100 and between the outer ends EL1 and ER1. Each center position CL1, CR1 is closer to the lower frame 146 on the side of the center position C1. In other words, near the nose bridge 142B contained in the spectacle frame 140 , the spectacle frame 140 has at least two second mounting structures 200B that can be mounted on the lower frame 146 contained in the spectacle 100 .

＜Changed example＞ As mentioned above, although this invention was demonstrated using each embodiment, the technical scope of this invention is not limited to the range described in the said embodiment. It is obvious to those skilled in the art that various changes and improvements can be added to the above-described embodiment.
