Description

Lens positioning structure (1)

The invention provides a lens positioning structure (1), which is mainly for disassembling/assembling a lens group of a movable interchangeable lens, and can obtain an accurate positioning by a simple operation, so as to facilitate the user to replace the lens. It is possible to maintain a good orientation restriction between the member and the member without damaging the relevant component assembly.

The lens set that is used to correct the vision and block the excessive light from the outside is convenient for the user to change the lens according to personal preference, and the frame, the temple and the functional lens are designed to be easily disassembled and easily assembled. Users can assemble the required functional lenses when appropriate. Such eyeglasses have always been actively developed by related companies to provide more choices in the consumer market.

Here, the relevant industry is proposed to propose such a type of glasses that are allowed to be replaced and disclosed, such as: the certificate number disclosed in 103.03.21: M474925 "lens positioning structure (four)" new case, announced in Certificate No. of 103.03.21: M474928 "Lens Positioning Structure (3)" New Case, Announcement No. 104.11.11 Certificate No.: M512140 "Lens Positioning Structure (6)" New Case, Announcement No. 105.01.01 Certificate No.: M515119 In the new case of "Lens Positioning Structure (5)", the above-mentioned related lens sets with easy interchangeable lenses are indeed expected to function in use.

The inventor of the present invention is for disassembling/or assembling the lens assembly having the quick-change lens as described above, and can provide a simple operation to achieve the desired exact positioning by using another new form of the group design. The user can maintain a good orientation restriction between the member and the member without changing the associated component assembly portion.

The invention is based on the fact that the eyeglass assembly of the movable movable replacement lens is disassembled or assembled into the intended lens, and the utility model can be easily operated. The lens assembly here comprises at least one preset form. a frame, at least one functional lens, and two mirror legs; the upper and lower portions of the rear end of the frame are recessed into holes, so that a section of the rod extending outwardly from the corresponding portion of the front end can be introduced when being pushed in The aforementioned hole maintains the temple and the frame in a pivotal shape; and the predetermined section on the outer side of the functional lens forms at least two or more protrusions as a transparent area held between the frames to be received therebetween The corresponding range of the push-in temple is limited to the space where the upper and lower lugs and the middle protrusion are separated, so that the functional lens is limited to one end of the temple; in the pre-fetching, the functional lens only needs to fold the mirror inward, The orientation of the partitioned space at one end of the temple is transferred, and the combined functional lens is freely supported by the restricted convex portion, which facilitates the removal of the hand from the end of the frame.

The main purpose of the present invention is to disassemble or assemble the functional lens between the glasses assembly. For the purpose of easy operation, the lens assembly is a frame including at least one preset shape, at least a functional lens and a two-legged foot; wherein the upper and lower parts of the rear end of the frame are recessed with a hole to allow the leg to extend outwardly from the corresponding end of the front end to be introduced when pushed in The aforementioned hole is such that the temple is pivotally connected to the frame; and the improved portion of the present invention is that the predetermined section of the outer side of the functional lens is formed with at least two or more protrusions as being introduced The transparent area maintained by the frame can be restricted to be pushed into the temple The range is defined by the space where the upper and lower lugs and the middle protrusion are separated, so that the functional lens is limited to one end of the temple; at the pre-fetching, the functional lens only needs to fold the temple inward so that the temple acts at one end. The orientation of the compartment is transferred, and the combined functional lens is freely constrained, which facilitates the removal of the hand from the end of the frame.

A second object of the present invention is to extend a hook portion of at least one or more of the predetermined range of the functional lens position of the lens assembly on the outer side, so as to facilitate the corresponding penetration in the transparent area between the frames. The recessed portion of the portion is defined as the orientation between the functional lens and the frame.

A third object of the present invention is to provide a short form for the protrusion between the upper and lower lugs of one end of the lens body included in the eyeglass assembly, so as to maintain a state in which the deployment shape is on the inner side of the frame. Interval, in order to facilitate the folding of the temples inward, the functional lens can be removed from the body.

A fourth object of the present invention is that the projections included in the lens assembly are formed in a longer shape between the upper and lower lugs of one end of the action, so that the expansion is a support portion on the inner side of the frame. Close contact, in order to reduce the distance between the convex portion and the convex portion of the corresponding portion of the functional lens when the mirror foot is folded inward, thereby preventing the functional lens from falling out.

The lens positioning structure (1) designed in the present invention (such as FIG. 1) mainly disassembles or assembles the functional lens between the eyeglass assembly 4, and is used for easy operation. The assembly 4 is composed of at least one preset frame 1 and at least one functional lens 2 and two temples 3; wherein the upper and lower portions of the frame 1 are recessed with holes 11 to allow the temples 3, a section 32 extending outwardly from the corresponding end of the front end can be introduced into the hole 11 (as shown in FIG. 2) when being pushed in, so that the temple 3 and the frame 1 are pivotally connected; and the present invention is improved here. The portion is: the outer side of the functional lens 2 is configured to form at least two or more protrusions 21 as a transparent portion 12 that is held between the frame 1 and can be restricted to be pushed into the temple 3 The range is defined by the space 34 in which the upper and lower lugs 31 and the intermediate protrusions 33 are separated (as shown in Figs. 3 and 6), so that the functional lens 2 is limited to one end of the temple 3 (as shown in Figs. 2 and 5); To remove the functional lens 2, it is only necessary to fold the temple 3 inward (as shown in Fig. 7) so that the temple 3 acts at the end of the compartment 3 The four orientations are shifted, and the combined functional lens 2 can be freely supported by the restricted convex portion 21, which facilitates removal of the hand from the end of the lens frame 1 (as shown in Fig. 8).

The aforementioned lens assembly 4 includes a functional lens 2 positioned on the outer side by a predetermined range of at least one or more hook portions 22 (as shown in FIG. 1) to facilitate the introduction of the space between the frames 1 The region 12 can be cut into the concave portion 13 corresponding to the corresponding portion (as shown in Fig. 6). As the orientation limitation between the functional lens 2 and the lens frame 1.

The protrusions 33 between the upper and lower lugs 31 of the one end of the temple 3 included in the aforementioned lens assembly 4 are in a shorter form (as shown in FIG. 4), so that the expansion is in the inner side of the frame 1. The side support portion 14 maintains a space to facilitate the folding of the temple 3 inwardly to facilitate the removal of the functional lens 2 (as shown in Figures 7 and 8).

And the protrusion 33' between the upper and lower lugs 31 of the one end of the lens assembly 4 is in a longer form (as shown in FIG. 9), so as to be in the unfolded shape with the frame 1 The support portion 14 on the inner side is in close contact to facilitate the distance 23 between the convex portion 21 and the convex portion 21 which can be held inwardly against the temple 3 and the end portion abuts against the corresponding portion of the functional lens 2 [FIG. 10] 〕, to prevent the functional lens 2 from falling out.
