[0002]

2. Description of the Related Art Glasses having a pad position adjusting mechanism configured to allow a user to adjust the relative position between the pad and the glasses have been known. Such a pad position adjusting mechanism is provided with a screw for raising and lowering the position of the pad up and down, and by rotating the head of the screw, the pad attached to the shaft of the screw is moved relative to the eyeglasses. It relatively displaces (see Japanese Utility Model Laid-Open No. 51-126148). Further, as another pad position adjusting mechanism, there is known a configuration in which a worm screw is screwed to a rack to which a pad is attached, and a worm screw rotatably attached to a frame portion between left and right lenses is turned. Causes the pad to be displaced (see Japanese Utility Model Application Laid-Open No. 52-66447).

[0003]

However, such a pad position adjusting mechanism has no rims (frames) of the lens, and has no rimmed glasses in which a nose pad is attached to a bridge connecting the left and right lenses, or a lens. However, it is difficult to apply the present invention to a lens-integrated sunglass in which the edge of the lens is provided only at the upper end portion along the eyebrows.

In the pad position adjusting mechanism disclosed in Japanese Utility Model Laid-Open Publication No. Sho 52-66447, a worm screw serving as an operating wheel for pad position adjustment is provided between the left and right lenses by a structure in which a worm screw is screwed into a rack. It is provided below the connecting portion that straddles. This configuration is constrained by the structure that screwes the worm screw into the rack, and if the worm screw is placed at the upper end of the edge of the lens, when the pad is raised, the rack jumps out of the edge or bridge of the lens and rises. I will. At this time, if the user touches the glasses with his or her fingers while wearing the glasses, the rack may hit the face. Therefore, such a pad position adjusting mechanism does not include two lenses on the left and right, and a lens-integrated sunglass that requires a pad position adjusting screw (knob) to be provided on the upper end portion of the edge of the lens, or In addition, it is difficult to apply the present invention to frameless glasses that do not have a lens edge and require a pad position adjusting screw on the bridge.

Instead, it is displaced in conjunction with the position of the pad. Therefore, when trying to adjust the pad position while wearing glasses having such a pad position adjusting mechanism, it is difficult to confirm the position of the head of the screw, and for the user, the pad while wearing the glasses is difficult. It is difficult to adjust the position. Also, if such a pad position adjusting mechanism is applied to sunglasses or frameless glasses with an integrated lens, a part of the screw may protrude from the edge or bridge of the lens, and the screw may hit the face.

The present invention relates to sunglasses with an integrated lens,
An object of the present invention is to provide a pad position adjusting mechanism for spectacles that can be applied to frameless spectacles and that can easily adjust the pad position while wearing spectacles.

The frame 11 includes a rim 11a and a temple 17, and a lens 12 is mounted on the rim 11a. The lens 12 is an integrated lens that is not separated into two parts, left and right, and is held by the rim 11a. The vicinity where the pad 16 is arranged is notched so as not to interfere with the pad 16. The lens 12 is a colored plastic lens.

The pad position adjusting mechanism P includes a screw 13, a support member 14, and a displacement member 15, and the displacement member 1
A pad 16 is attached to 5. The pad position adjusting mechanism P is attached to the center of the rim 11a, and is installed on the back (face side) of the lens 12. The operation unit 13T provided on the top of the screw 13 is a knob for adjusting the pad position. By turning the operation unit 13T left and right, the pad 16 moves up and down, and the relative position of the pad 16 with respect to the sunglasses 10 is adjusted. Is displaced. The operation unit 13T is exposed on the front surface of the rim 11a, and the user can adjust the pad position while wearing the sunglasses 10.

When the operation unit 13T is turned, the relative position between the pad 16 and the sunglasses 10 is displaced. That is, since the pad 16 is in contact with the predetermined position of the nose, the lens 12 and the frame 11 of the sunglasses 10 are displaced up and down with respect to the face, and the sunglasses 10 are set to positions suitable for the user.

FIG. 2 is a perspective view showing the entire pad position adjusting mechanism P. FIG. 3 is a perspective view showing the displacement member 15.

The support member 14 is connected to the center of the rim 11a, is formed in a prismatic shape, and extends downward.
The screw 13 includes a shaft portion 13G and an operation portion 13T integrally fixed to an end of the shaft portion 13G. The operation unit 13
The operation unit 1 is provided at the center of the rim 11a.
The shaft portion 13G extending from 3T is formed in a male screw,
It is inserted into the support member 14. However, screw 13
Is rotatable about an axis. Part of the operation unit 13T is exposed to the front in the center of the rim 11a,
The user can turn the knob left and right as a knob for adjusting the pad position. When the operation unit 13 is rotated, the screw 13 does not displace in the axial direction X.

A pad 16 is attached downward (in the direction of the nose) to the displacement member 15 formed in a prismatic shape. The displacement member 15 is screwed with a shaft portion 13G of the screw 13, and a screwed portion (see FIG. 3) 15R is formed as a female screw. Note that the threaded portion 15R of the displacement member 15 is formed of metal.

The support member 14 has a hole large enough to fit the displacement member 15 as shown by a broken line.
The displacement member 15 screwed with G is guided and supported by the support member 14 so as to be freely displaceable. That is, the displacement member 15 is displaced along the axial direction X, and is partially inserted into a hole provided in the support member 14.

By turning the operation unit 13T, the screw 13
Is rotated about the axis, an urging force is applied to the threaded portion 15R of the displacement member 15 that is screwed with the shaft portion 13G, but the displacement member 15 engages with the inner wall of the hole of the support member 14. Do not rotate around the axis. Therefore, the displacement member 15 is displaced along the axial direction X. When the operation unit 13T is turned counterclockwise, the displacement member 15 is lowered, and when the operation unit 13T is turned clockwise, the displacement member 15 is raised.

The displacement member 15 is displaceable in a state where the displacement member 15 is fitted into the support member 14. Therefore, the distance D from the bottom surface of the hole of the support member 14 to the opening of the support member 14 is a fluctuation range of the displacement member 15.

As described above, according to the first embodiment, when the operating portion 13T of the screw 13 is turned, the screw 13 rotates around the axis, and the shaft 13G and the screw 13G are rotated in conjunction with the rotation of the screw 13. The combined displacement member 15 is displaced along the axial direction X. Thereby, the relative position of the pad 16 attached to the displacement member 15 with respect to the sunglasses 10 is displaced, and the position of the pad suitable for the user is adjusted.

The operating portion 13T of the screw 13 does not displace in the axial direction X at the center of the rim 11a even when the screw 13 is rotated. Therefore, the position of the operation unit 13T, which is a knob for adjusting the pad position for the user, is always at a fixed position, and the user can touch the operation unit 13T with his / her finger even when wearing the sunglasses 10 to adjust the pad position. It can be easily adjusted.

A screw 1 composed of an operating part 13T and a shaft part 13G
3 and the displacement member 15 are screwed together,
The displacement member 15 is rotated by the rotation about the axis of the
And the operation unit 13T
Is arranged at the uppermost part in the pad position adjusting mechanism P, and the displacement member 15 is arranged at the lowermost part in the pad position adjusting mechanism P. Accordingly, the pad position adjustment can be performed even for the lens-integrated sunglass 10 in which the rim 11a is provided only at the upper end portion of the lens 12 and the frame portion cannot be provided between the left and right lenses as in the first embodiment. The mechanism T can be applied.

The displacement member 15 can be displaced only in a state in which it is fitted into the support member 14 and is guided and supported. Therefore, regardless of the position of the pad 16, the shaft portion 13 </ b> G of the screw 13 is connected to the support member 14 and the displacement member 15
Therefore, it is not exposed to the outside. Therefore, there is no fear that the thread 13Y of the screw 13 hits the face.

Since the threaded portion 15R of the displacement member 15 is formed of metal, the contact portion between the shaft portion 13G and the threaded portion 15R slides when the operating part 13T is rotated,
The screw 13 does not run idle. Therefore, pad 1
6 can be precisely adjusted.

Since the pad 16 is displaced by the screw 13, the sectional area of the pad position adjusting mechanism P is
It can be reduced to 3G. Thus, even when the pad position adjusting mechanism P is attached to the lens-integrated sunglasses 10, there is no need to worry that the field of view is blocked by the pad position adjusting mechanism P.

Since the pad position adjusting mechanism P having a simplified structure is provided at the center of the rim 11a of the sunglass 10, the number of components of the entire sunglass 10 can be reduced, and the manufacturing process can be simplified.

Instead of the lens-integrated sunglasses 10, the pad position adjusting mechanism T may be provided on general glasses having rims provided on the left and right lenses, respectively.

FIG. 4 is a perspective view showing a pad position adjusting mechanism according to the second embodiment. The difference from the first embodiment is that the exposed portion of the operation section 13T of the screw 13 is on the back side (face side), and the other points are the same as the first embodiment.
