Description

Slider for folding glasses {SLIDER FOR SPECTACLES}

The present invention relates to a slider for fold eyeglasses, and more particularly, to the provision of an improved slider applied to fold eyeglasses that can minimize volume to facilitate storage and portability when folded.

Folded glasses to minimize the volume when folded as well as easy to carry as well as to look through Figures 6 and 7 as follows.

The conventional folding eyeglasses 1 are provided with a slider 3 so as to narrow the gap between the eyeglass frames 2 at positions connecting the middle portions of the eyeglass frames 2, and both sides of the eyeglass frames 2. The leg 4 is connected to the pivoting portion 5 via the torsion spring to be folded downward in the 90 ° direction, and the rear portion of the leg 4 is folded in the inner direction of the glasses in the middle of the leg 4. It is configured by connecting the hinge 6 so that it can be lost.

In order to fold the glasses in the above configuration, insert the slider to connect the glasses frame to reduce the overall width of the glasses, and rotate the legs downward through the rotating portion connecting the legs and the glasses frame.

At the same time, the rear part of the leg is folded around the hinge to the inner side of the glasses, so the overall width of the glasses frame is reduced, and the legs are folded on both sides and the bottom of the glasses frame. It is a structure that can be stored in a thick case.

Slider 3 of the folding glasses as described above is coupled to the slide rail (9) to the slide tubes (7, 8) fixed to the upper surface of the eyeglass frame (2) and one slide tube (7) and bolt (9) It is fixed to, so as to be able to slide with the other slide tube (8) so that the width of the glasses frame (2) can be varied.

A stopper 10 is provided at an outer end of the slide rail 9 that is slidably coupled to the slide tube 8 to prevent the slide rail 9 from being separated.

The bottom surface of the slide rail (9) forms a spring groove (11) in the longitudinal direction and the leaf spring (12) fixed to the bottom surface of the slide tube (8) is recessed to slide the slide rail (9) to the slide tube (8) direction To prevent fluidity after operation.

In the prior art as described above, since the cross sections of the slide tube and the slide rail have a rectangular shape, the slide rail is pushed upward by a spring from the bottom of the slide rail, but the flow becomes severe after the sliding operation process or completion of operation.

That is, in the initial stage of engagement, the torsional flow in the axial direction of the slide rail is small due to tight dimensional management, but as time passes, the play between the slide tube and the slide rail occurs due to friction and abrasion. Compensation is made but practically no play is made.

Since the cross-sectional shape of the slide tube and the slide rail is rectangular, wear is performed on four sides. When the spring pushes the slide rail to compensate for such wear, only the upper surface of the slide rail and the inner upper surface of the slide tube are in close contact. Both sides are in a state in which the play occurs as it is, and the torsion (play) in the axial direction of the slide rail is deepened through the play of the left and right sides.

If the play is severe as described above, there is no big problem in folding and storing, but even when wearing glasses, severe shaking occurs, so that the feeling of wearing is not good. Causes bad deterioration.

In the present invention, a slider provided to narrow or widen the distance between the glasses frame in the middle portion of the glasses frame to which the lens is mounted as invented to solve the above problems, and folded downward on both sides of the glasses frame A bridge connecting to the rotating part via the torsion spring, a hinge connecting the rear portion of the leg to be folded in the inner direction of the glasses in the middle of the leg, and the slider is a slide tube fixed to the upper surface of the glasses frame In the folding glasses fixed to one slide tube in the bolt, and configured to vary the width of the eyeglass frame by the slide rail that is interrupted by the stopper so as not to be separated from the other slide tube;

The slide tube fixed to the spectacle frame and the slide rail coupled to the slide tube are formed to have a trapezoidal cross section so that the upper surface and the three side surfaces of the slide rail are always connected to each other to exclude the phenomenon of torsion in the flow or axial direction. The slide rail position in which the slide rail reciprocates is characterized by further comprising a play prevention means for suppressing play by pushing the slide rail in the slide tube direction.

The present invention improves the slider applied to the fold eyeglasses to suppress the play of the play even if there is wear due to the initial installation as well as the frequent use to ensure excellent operability, as well as to prevent the flow in the adjusted state to provide a good fit It is an invention having various effects such as to increase convenience of users.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

The collapsible glasses 100 includes a slider 105 at a middle portion of the glasses frame 102 on which the lens 101 is mounted, so as to narrow or widen the interval of the glasses frame 102, and the glasses frame 102. Both sides of the bridge 107 is connected to the rotating portion 106 via the spring to be folded downward in the 90 ° direction.

The middle of the leg 107 is configured by connecting the hinge 108 so that the rear portion of the leg 107 can be folded in the inner direction of the glasses.

The slider 105 is coupled to the slide rails 112 to the slide tubes 110 and 111 fixed to the upper surface of the eyeglass frame 102 and fixed with one slide tube 110 and bolts 113 and the other. The width of the spectacle frame 102 is varied by intermittent with the stopper 114 so as not to be separated from the slide tube 111.

In the present invention, the slider 105 is improved, and the slider 105 is rotated about the axial direction. In addition, even if there is wear, it is characterized in that the wear is excellent by suppressing the occurrence of play.

To this end, in the present invention, the slide tubes 110 and 111 fixed to the eyeglass frame 102 and the slide rails 112 coupled to the slide tubes 110 and 111 have a trapezoidal cross section in the flow or operation state in the operation process. Minimized torsion in the axial direction ensures smooth operation while increasing fit.

At the position of the slide tube 111 to which the slide rail 112 reciprocates, the slide rail 112 is further provided with a play prevention means 115 for always pushing the slide rail 112 toward the slide tube 111 to suppress the play.

The clearance preventing means 115 is pushed up the slide rail 112 in the direction of the slide tube 111 in the spring groove 116 is formed to be recessed to the bottom surface of the slide rail 112 while reducing the clearance to increase the sense of theft. The leaf spring 117 is inserted to enable the operable operation.

The spring groove 116 into which the leaf spring 117 is inserted prevents the leaf spring 117 from bending in the horizontal state or the spring groove 116 to always protrude in the direction of the slide tube 111 to maintain an arc shape. An arc-shaped support surface 118 is further integrally formed to support the leaf spring 117 so as to support the leaf spring 117.

In addition, the upper surface of the slide rail 112 is provided with a magnet 119 to enhance adhesion with the slide tube 111, the slide tube 111 of the position when the maximum separation and storage of the slide rail 112 In addition, the magnet 119 is provided at a position corresponding to the magnet 119, thereby further strengthening the coupling force so as to increase the operability together with the play prevention.

Slider for folding glasses of the present invention as described above,

When the folded glasses 100 are to be worn, the legs 107 are spread out and the stored slad 105 is separated, and the wearable glasses are normally worn as if the glasses are to be worn. ) To narrow the overall width of the glasses 100.

Then, using the rotating parts 106 of both sides of the eyeglass frame 102, the whole leg 107 is folded in line with both sides of the eyeglass frame 102, and the hinge 108 of the leg 107 again. By rotating in the inner direction of the eyeglasses 100, the legs are located on the lower side of the eyeglass frame 102, so that the shape has a minimum thickness and volume can be easily carried and stored.

As described above, the entire width of the glasses 100 is varied by the slider 105 in the process of folding and unfolding the glasses 100. In the present invention, there is no shaking even in the folding process and a twist or play occurs in the axial direction even when the operation is completed. There is no wearing comfort.

This is because the cross-sectional shapes of the slide tubes 110 and 111 and the slide rail 112 constituting the slider 105 are trapezoidal, and the slide rail 112 is moved upward from the trapezoid downward by the play prevention means 115. Since the slide rails 112 are always in close contact with the slide tubes 110 and 111, they are always pushed in the direction.

That is, the slide rails 112 having the same cross section are always pushed upward in the slide pipes 110 and 111 having the trapezoidal cross section, and the upper surface and the left and right sides of the trapezoid cross section are always connected in an optimal state so that there is a play. This is because there is almost no state.

The clearance preventing means 115 for connecting the slide tubes 110 and 111 and the slide rails 112 is always pushed upward and connected to an arc-shaped plate in the spring groove 116 formed on the bottom surface of the slide rail 112. The spring 117 is always pushed up.

In addition, the magnet 119 provided on the upper surface of the slide rail 112 is a magnet provided in the slide tube (110, 111) at the same position as the magnet 119 when the slide rail 112 is close to the storage position or detachment position. 120 is coupled by the magnetic force is made possible by increasing the adhesion even more.
