Description of the Invention (I) The present invention relates to a pair of glasses for automatic distance adjustment, especially a lens angle that can be adjusted according to the near or far distance to reduce The phenomenon of lens center shift and angle error provides users with comfortable glasses. Referring to Figure 1, when looking far away with glasses wearing corrective optical lenses, the line of sight a passes through the center of the lens 100 and is at 90 degrees to the lens 100 (see Figure 3); (Head down about 30 cm) 'Convergence of both eyes, the line of sight a, deviates from the center of the lens 100, and forms an error of 0 angle with the lens 100 (see Fig. 4). The distance L of the line of sight a' from the center of the lens 100 is: The angle error and the center offset error cause fatigue and discomfort of the eyes when looking close, and currently the commercially available glasses cannot compensate for the lens angle according to the wearer's looking close. This is the work of the present invention. The main reason is. The reason is that the main object of the present invention is to provide glasses with automatic distance adjustment. The main frame of the glasses is provided with a chute for fixing the slide of the slide rail on the lens frame. The lens center offset can be corrected manually or automatically. Angle error and other issues to improve the comfort of wearing glasses. Another object of the present invention is to provide glasses for automatic distance adjustment, in which the middle frame 4 of the main frame is provided with a frame seat with a slide groove, and the slide groove can be placed inside the mirror frame by sliding feet. The displacement of the slippery foot can just compensate the deviation of the center of the lens, so that the center of the lens after correction is still on the line of sight. "Another object of the present invention is to provide an automatic distance adjustment lens, in which between the main frame and the lens frame A return shrapnel can be added to allow the wearer to automatically return the mirror frame to its original position when the wearer lifts his head from a close view to a far view. In order to let your reviewers have a better understanding of the present invention, here is a detailed description of the present invention with the illustrations: ㈠ Schematic part: Figure 1: Appearance view when wearing glasses when looking far away (in head-up view).

Description of the invention (3> Refer to Figures 5 to 8 together. The feet 11 on both sides of the main frame 1 of the present invention are respectively provided with a sliding groove m. Each end has a top stop U2 and a bottom stop 113, respectively, as a free stroke controller, and the inside of the chute m It can be extended by the stopper 21 at the front end of the chute tip 2. The chute tip 2 is a unilateral opening, slightly curved, and the inner edge of the sipe-shaped slot 22 has a cross hole 23 for the knob. 3 The front end of the knob 31 extends, the knob 3 can first penetrate the through hole 41 ′ of the mirror frame 4 and then protrude into the cross hole 23 of the slide end 2; see FIG. 8, when the knob 3 is convex When the block 31 is placed in the flat position of the 槽 -shaped slot 22 7jc, the stopper 21 of the slide rail tip 2 is not stretched outward, so it can freely travel above the top 111 and bottom 113 of the main groove 1 (See the imaginary line position in Fig. 8) 'in order to adjust the displacement of the mirror frame 4 to the outside (as shown in Fig. 7). When the projection 21 of the mirror frame 4 slides to a position within the bottom stop 113 of the main frame 1, Just turn the knob 3, and its convex block 31 is vertically locked in the cross hole 23, so that the stopper 21 of the mirror frame 4 is fixed in the bottom stop 113 and cannot be moved. In addition, there is a tip hole 24 on the left side of the channel-shaped slot 22 of the slideway tip 2, and a fixed tip 5 can pass through another perforation 42 of the mirror frame 4 and be fixed in the hole 24 so that the slideway tip 2 and The mirror frame 4 is integrated into one body (or fixed by screwing), so that the displacement of the mirror frame 4 in front of the main frame 1 is caused by the displacement of the slideway tip 2, so it can be attached by the change of the knob 3 The lens frame 4 with spectacle lens is adjusted from FIG. 5 to the position shown in FIG. 7 so as to reduce the compensation for the lens center offset when reading and writing with the head down (mainly to compensate for angular deviation). In order to match the displacement of the mirror frame 4 in front of the main frame 1, the frame 12 of the main frame 1 has a frame 6 on both sides of the frame 12, which is A sliding groove 61 with a single-side opening can be extended by a sliding rod 43 on the side of the mirror frame 4. The top of the sliding rod 43 is an inner sliding foot 431, which prevents the sliding rod 43 from leaving the frame base. 6. As shown in Fig. 8, when the mirror frame 4 is not moved forward, the inner slide foot 431 is hooked on the mouth of the slide groove 6 of the frame seat. When the mirror frame 4 is moved forward, the slide bar 43 may Those who extend into the chute 61 of the frame base 6. Please refer to FIG. 9. In the present invention, a returning spring 8 is added between the main frame 1 and the mirror frame 4. The returning spring 8 is fixed at the top edge of the main frame 1, and the other end of the returning spring 8 is extended. The long groove 44 provided at the top of the mirror frame 4 slides inside; when you read and write down, you want to return to head up (hyperopia), and the return spring 8 can automatically restore the mirror frame 4 to the original frame 1 Fitted position. 83.3.10,000 (Please read the notes on the back before filling out this page) This paper size is applicable to ZTE National Standard Feng (CNS > A4 specification (210X297 mm) 452658 A7 _ B7__ V. Description of the invention (4 *) Please refer to As shown in Figures 10 and 11, when the present invention wears glasses and looks far away, the lens 100 has only the gravity W of the downward force, and no component of the gravity W, so the inner sliding foot 431 is at the position S outside the frame 6; When wearing glasses, see Figure 12 and Figure 13. As shown in Figure 12 and Figure 13, in addition to the vertical force of gravity W, the force W of the force of gravity W increased, thus forcing the lens 100 ° rotates along the downward arc surface. Due to the guide of the inner slideway tip 2 of the slide groove 111 of the main frame groove 1, the inner slide foot 431 is moved from the outer position S of the frame base 6 to the inner position S '. (S -► S '). Please also refer to the embodiments shown in FIGS. 14 to 17. In this case, a groove 12 may be provided on the footrests 11 on both sides of the main frame 1. The inner and outer sides also have a top stop 121 and a bottom stop 122 (see Fig. 17), and are fixed on the frameless lens 100 (or framed lens). There is a slideway tip 7, which is connected to the lens 100 as a whole, and the slideway tip 7 is also a positioning tip with a single side opening. The front end of the stopper 71 can be inserted into and fixed to the main frame 1. Above the groove 12 and inside the bottom stops 121 and 122, as shown in FIG. 9, when the stopper 71 is fixed on the top stop 121, the glasses are used for head-up viewing when viewed from a distance, and can be adjusted when the wearer reads his head down. The stopper 71 is fixed at the position of the lower stop 122, as shown in Fig. 15, which can compensate the deviation of the center of the lens, so that the center of the corrected lens is still in sight. "Please refer to FIG. Another embodiment diagram, in which the correction between the lens 100 and the main frame 1 can also be simply hooked on the lens 100 with the barb 13 on the main frame 1 as the travel restriction mechanism. Printed by Bei Gong Consumer Cooperative (please note the item on the back of M1S before filling out this page) In summary, the automatic far-near adjustment glasses of the present invention can use the slide rail tips on the mirror frame on the slide grooves on the main frame. Slip to correct lens center offset and angle errors to improve reading or close Those who are comfortable wearing glasses at the time, so they can be used in the industry, but the invention has never been published in the market or has been seen in other books and periodicals. It has actually complied with the legal requirements of the Patent Law, and applied for it in accordance with the law. 8 3,3.10,000 This paper ruler is applicable to China National Standard (CNS) A4 specification (210X297)
