3D glasses with adjustable frame width

The present invention relates to a pair of glasses, and more particularly to a 3D glasses that can adjust the width of the frame.

Since the production and distribution of 3D stereoscopic video, viewing 3D stereoscopic images has formed a trend. At present, it is still necessary to wear exclusive 3D stereo glasses to view 3D stereoscopic images. Generally speaking, when playing such 3D stereoscopic images, the player will provide the 3D stereo glasses for viewing to the viewers for free, and then recycle them for use after viewing.

However, the frame width of these freely provided 3D stereo glasses can hardly be adjusted. The operators usually only provide two different specifications of glasses for adults and children. In this way, not only the glasses manufacturers have to spend more money to produce glasses of different sizes, but also the size of the heads of the viewers, men and women, and the size of the frames of the single size specifications are fixed, and cannot be adapted to all viewers. This directly affects the viewing quality of the viewer.

In view of this, it is necessary to provide a 3D glasses that can adjust the width of the frame.

The adjusting component 30 includes a limiting component 31, a nose pad 32 and a tension spring 33. The limiting component 31 includes an upper limit portion 311, a lower limit portion 312, a connecting portion 313 connected between the upper and lower limit portions 311 and 312, and a cover plate 316. Two limit blocks 314 are vertically extended at two ends of the upper and lower limit portions 311 and 312 respectively in a direction away from the connecting portion 313. The distance between the two opposite faces of the first and second guiding blocks 15, 16 on the same left front frame 11 or right front frame 12 is equal to the two surfaces of the upper and lower limit portions 311, 312 facing away from the connecting portion 313 The vertical distance between. A guiding groove 315 is defined in each of the central portions of the two sides of the connecting portion 313 perpendicular to the upper and lower limit portions 311 and 312. The cover plate 316 is disposed on a side of the upper and lower limit portions 311 and 312 and the connecting portion 313 away from the left and right front frames 11 and 12, and the cover plate 316 has substantially the same shape as the connecting portion 313. The nose pad 32 includes a bracket 321 and a spacer block 322 fixed at a position intermediate the top end of the bracket 321 . The other end of the spacer block 322 is connected between the two limiting blocks 314 of the lower limit portion 312 . The bracket 321 is bent at an angle and the angle is toward the direction away from the limiting member 31. The tension spring 33 is a direct spring, and its two ends are respectively fixed on the fixing blocks 17 of the left and right front frames 11 and 12.

The limiting element 31 is disposed between the two opposite connecting ends 14 of the left and right front frames 11 and 12, and the two first guiding blocks 15 are located at the two limiting blocks 314 of the upper limit portion 311. The two second guiding blocks 16 are located between the two limiting blocks 314 of the lower limit portion 312 and are disposed on two sides of the spacer block 322. The two fixing blocks 17 are disposed. In the guide groove 315 on both sides of the connecting portion 313.

When a viewer whose initial width between the left ear frame 21 and the right ear frame 22 of the 3D glasses 100 having a face width is larger than the adjustable frame width wears the 3D glasses 100 of the adjustable frame width, the left and right front frames 11. The pair of tension springs 33 are stretched, and the two fixing blocks 17 are moved away from each other in the guiding groove 315. The two first guiding blocks 15 are at the upper limit portion 311. The two limiting blocks 314 move in a direction away from each other, and the two second guiding blocks 16 move in a direction away from each other between the two limiting blocks 314 of the lower limit portion 312 until the The width of the 3D glasses 100 that adjusts the width of the frame is equal to the width of the face of the viewer. When a person whose width is too large is wearing the 3D glasses 100 of the adjustable frame width, the two first guiding blocks 15 respectively abut against the two limiting blocks 314 of the upper limit portion 311, the two The second guiding blocks 16 respectively abut against the two limiting blocks 314 of the lower limit portion 312, thereby avoiding excessive stretching of the tension spring 33. The position of the nose pad 32 remains unchanged during the width adjustment of the adjustable frame width of the 3D glasses 100.

Referring to FIG. 4, the adjustable frame width 3D glasses 100a provided in the second embodiment are different from the adjustable frame width 3D glasses 100 provided in the first embodiment in that the upper and lower limit portions 311, 312 are A plurality of limiting ribs 317 are protruded from a surface facing away from the connecting portion 313, and the limiting ribs 317 are made of a deformable material such as rubber. The tension of the tension spring 33 is smaller than the resistance of the limiting rib 317 to the first and second guiding blocks 15, 16. The first and second guiding blocks 15 and 16 are respectively disposed between the adjacent two limiting ribs 317.

The left and right front frames of the adjustable frame width 3D glasses provided by the present invention are connected by a tension spring, and the stretching distance between the left and right front frames through the limiting members and the guiding blocks disposed on the left and right frames Limiting is performed to achieve adjustment of the frame width and to effectively prevent damage to the glasses due to excessive stretching.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
