Patent Application
20250138334
The present invention relates to a spectacle lens replacement structure, and in particular, refers to an innovative design that can quickly detach the lens from the frame and assemble it to the frame.
Conventional glasses often provide glasses with lenses that can be easily disassembled and assembled, allowing users to replace the lenses depending on the usage status, occasion, and when the lenses are damaged.
For example, Taiwan Pat. Pub. No. 1268384B “Eyeglasses with Lenses Changeable”. A perforation arranged in the center of the frame. An elastic engage block arranged above the nose bridge of the frame. A protruding rod protruding from the front end of the engage block. The protruding rod passes through the perforation. When the lens is assembled with the frame, a snap hole arranged in the center of the lens, and the engage block is inserted into the snap hole of the lens to fix the lens to the frame.
Although the structure of Taiwan Pat. Pub. No. 1268384B can achieve the effect of quick disassembly and assembly of the lens. However, the perforation of the frame penetrates the front surface of the frame, and the protruding rod penetrates outside the perforation, which damages the overall aesthetics of the glasses and thus affects the commercial value of the glasses.
The inventor of the present invention has developed the present invention in view of the shortcomings of the above-mentioned existing previous cases in actual implementation and use.
The main purpose of the present invention is to provide a spectacle lens replacement structure, in which the wearer can change the lens by himself at any time, and the lens changing is extremely convenient and fast. At the same time, the lens replacement structure will not damage the integrity of the spectacle from a perspective that a third party can view.
The above-mentioned purpose of the present invention is achieved by the following technologies:
The spectacle lens replacement structure as mentioned above, a protruding limiting protrusion is provided on the bottom surface of the insertion piece, when the insertion piece is inserted into the lock hole, the limiting protrusion will be adjacent to the front surface of the rear side wall.
The spectacle lens replacement structure as mentioned above, the switch has a pressing force-applying part that protrudes backward and is provided at one end corresponding to the clamping portion, when the switch is accommodated in the long opening, the pressing force-applying part will relatively protrude from the rear surface of the rear side wall.
In order to have a more complete and clear disclosure of the technical content, the purpose of creation and the effect achieved by the present invention, it is explained in detail below, and refer to the disclosed drawings and drawing numbers together.
First, in this article, the terms “forward,” “front side,” etc. are defined as the direction indicated by the arrow F shown on each view in the figure. The terms “backward,” “rear side,” etc. are defined as the direction indicated by the arrow B shown on each view in the figure. The terms “upper,” “top side,” etc. are defined as the direction indicated by the arrow U shown on each view in the figure. The terms “lower,” “bottom side,” etc. are defined as the direction indicated by the arrow D shown on each view in the figure.
Referring to
The spectacle lens replacement structure of the present invention includes a frame 1, a switch 2, and a lens 3, wherein
Referring to
First, the clamping portion 21 of the switch 2 corresponds to the pivot connecting portion 14 of the frame 1, and the two clamping claws 211 of the clamping portion 21 clamp the pivot ball body 15 on the pivot connecting portion 14, so that the switch 2 is pivotally connected to the frame 1, and is correspondingly accommodated in the long opening 16 of the frame 1.
When the upper edge of the lens 3 is inserted into the inlay groove 11 of the frame 1, the concave groove 32 on the lens 3 allows the pivot connecting portion 14 of the frame 1 that protrudes from the front side wall 12 and is located across the inlay groove 11 and the clamping portion 21 of the switch 2 that holds the pivot connecting portion 14 to enter therein, so that the upper edge of the lens 3 is inserted into the inlay groove 11 of the frame 1 without any obstruction.
Then, press the end of the switch 2 corresponding to the insertion piece 22 toward the front side wall 12 of the frame 1 so that the insertion piece 22 is inserted into the closed lock hole 31 of the lens 3, thereby fixing the lens 3 to the frame 1.
In a preferred embodiment of the spectacle lens replacement structure according to the present invention, a protruding limiting protrusion 23 is provided on the bottom surface of the insertion piece 22. When the insertion piece 22 is inserted into the closed lock hole 31, the limiting protrusion 23 will be close to the front surface of the rear side wall 13 of the frame 1 to form a blocking point to prevent the insertion piece 22 of the switch 2 from easily detaching from the closed lock hole 31 of the lens 3, so that the assembly relationship between the lens 3 and the frame 1 is stabilized.
When the lens 3 is to be removed from the frame 1, the insertion piece 22 of the switch 2 is disengaged from the closed lock hole 31 of the lens 3, so that the lens 3 can no longer be locked by the switch 2 and can be removed from the inlay groove 11 of the frame 1.
In a preferred embodiment of the spectacle lens replacement structure according to the present invention, the switch 2 has a pressing force-applying part 24 that protrudes backward and is slightly tilted to the side, and is provided at one end corresponding to the clamping portion 21. When the switch 2 is accommodated in the long opening 16 of the frame 1, the pressing force-applying part 24 will relatively protrude from the rear surface of the rear side wall 13 of the frame 1, at the same time, the pressing force-applying part 24 is offset toward the outside relative to the axis of the pivot ball body 15, so that the two opposite ends of the switch 2 can move like a seesaw after being pivoted to the pivot ball body 15.
Therefore, when the lens 3 wants to be removed from the frame 1, it can be pressed directly from the pressing force-applying part 24 of the switch 2. After being pressed, the pressing force-applying part 24 of the switch 2 will rotate slightly with the pivot ball body 15 as the axis. This slight rotation causes the insertion piece 22 of the switch 2 to separate from the closed lock hole 31 of the lens 3. At this time, the lens 3 will no longer be locked and can be removed from the inlay groove 11 of the frame 1.
