The present invention relates to a pair of glasses, especially to a pair of glasses with changeable lenses based on the principle of magnetism. The glasses with changeable lenses feature on good limiter and easy operation.
Generally, eyewear available on the market is divided into various types such as sunglasses, optical glasses, sports glasses, safety glasses, etc. according to their functions. Or the eyewear is divided into a full frame type and a frameless type according to the frame it includes. Consumers select the eyewear according to personal interests and needs.
Holes for mounting lenses are located on two ends of an eyeglass frame. A threaded end being threaded and fixed by thread-like components is formed on an outer side of the holes for mounting lenses. After being cut and polished, the lens is mounted into the hole and fixed by the thread-like components threaded into the threaded end. Thus the lens is positioned in the hole firmly without falling off. However, it takes time and tools to thread the thread-like components into the threaded end. Once there is no tool available, the thread-like components can't be set up. This causes inconvenience to users during assembly processes.
In order to solve the problem mentioned above, an eyeglass assembly in Taiwanese Pat. Pub. No. M455172U1 is revealed. The eyeglass assembly mainly includes an eyeglass frame, positioning blocks and lenses. A lens-assembly hole is arranged at each of two sides of the eyeglass frame and is corresponding to the lens. A mounting channel is formed on an inner edge of the lens-assembly hole while a recessed mounting portion is set on each side of the eyeglass frame, corresponding to an outer edge of the lens-assembly hole. The positioning block is mounted into the recessed mounting portion on each side of the eyeglass frame. Thus the positioning block and the recessed mounting portion are pivotally connected. A fastening part is disposed on an edge on an upper end of the positioning block and corresponding to an upper end of the recessed mounting portion. Thus the positioning block locked into the recessed mounting portion is connected to and fixed in the eyeglass frame firmly by the fastening part. The lens is mounted and fixed in the mounting channel of the lens-assembly hole and then is pressed and positioned by the positioning block.
Although the above structure overcomes shortcomings of conventional design, there is room for improvement and a need to provide a novel structure of glasses with changeable lenses.
Therefore it is a primary object of the present invention to provide a pair of glasses with changeable lenses based on the principle of magnetism. The glasses with changeable lenses feature on good limiting and easy operation.
In order to achieve the above object, a pair of glasses with changeable lenses of the present invention includes a channel disposed on a bridge of an eyeglass frame. The channel communicates with a left frame and a right frame. The eyeglass frame is divided into an upper part and a lower part by the channel. The upper part and the lower part are disposed with a magnetic part respectively. By the attracted magnetic parts that close the channel, the lenses are positioned. Or the two magnetic parts are pulled and separated to open the channel so that the lenses can be replaced. Thereby the lenses are disassembled and assembled easily and conveniently.
The upper part includes an upper chamber used for receiving a first magnetic part correspondingly. At least one first mounting hole is arranged in the upper chamber while at least one first pin is disposed on the first magnetic part. The at least one first pin is mounted into the at least one first mounting hole correspondingly.
Similarly, the lower part includes a lower chamber used for receiving a second magnetic part. The lower chamber is set with at least one second mounting hole and the second magnetic part is arranged with at least one second pin. The at least one second pin is inserted into the at least one second mounting hole correspondingly.
A protruding piece is set on the upper chamber and a slot is formed between the protruding piece and the first magnetic part. Hooks are set on a surface of the lower part and passed through the slot of the upper part to be located in the upper chamber and limited by the protruding piece.
A protrusion is disposed on a surface of the upper part of the eyeglass frame while a recess is mounted on a surface of the lower part. The upper and the lower parts are connected to each other more securely by the protrusion being mounted into the recess.
1. The glasses with changeable lenses of the present invention are disassembled and assembled conveniently based on the principle of magnetism.
2. The magnetic parts are secured firmly by the pin being mounted into the mounting hole correspondingly.
3. The opening size of the channel is limited by the hooks worked together with the protruding piece. Thus the lenses will not fall off in case of a crash.
FIG. 2 is a schematic drawing showing a partial assembly of hooks in an upper chamber of an embodiment according to the present invention;
FIG. 3 is a longitudinal cross sectional view of a closed channel of an embodiment according to the present invention;
FIG. 4 is a longitudinal cross sectional view of an exposed channel of an embodiment according to the present invention;
FIG. 5 is a perspective view of another embodiment according to the present invention;
FIG. 6 is a longitudinal cross sectional view of another embodiment according to the present invention.
Refer to FIG. 1 and FIG. 2, a pair of glasses with changeable lenses of the present invention mainly includes a channel A disposed on a bridge 11 of an eyeglass frame 1. The channel A communicates with a left frame and a right frame 12. The eyeglass frame 1 is divided into an upper part 2 and a lower part 3 by the channel A.
The upper part 2 includes an upper chamber 21 used for receiving a first magnetic part 4 correspondingly. A protruding piece 22 is set on the upper chamber 21 and a slot 23 is formed between the protruding piece 22 and the first magnetic part 4.
The lower part 3 includes a lower chamber 31 used for receiving a second magnetic part 5. The second magnetic part 5 and the first magnetic part 4 are attached to or separated from each other. Hooks 32 are set on a surface of the lower part 3. The hooks 32 are passed through the slot 23 of the upper part 2 to be located in the upper chamber 21 and limited by the protruding piece 22.
While being assembled, as shown from FIG. 1 to FIG. 4, the first magnetic part 4 and the second magnetic part 5 are mounted into the upper chamber 21 of the upper part 2 and the lower chamber 31 of the lower part 3 on the bridge 11 of the eyeglass frame 1 respectively. At least one first mounting hole 24 is arranged in the upper chamber 21 while at least one first pin 41 is disposed on the first magnetic part 4. The at least one first pin 41 is mounted into the at least one first mounting hole 24 correspondingly. Similarly, the lower chamber 31 is set with at least one second mounting hole 33 and the second magnetic part 5 is arranged with at least one second pin 51. The at least one second pin 51 is inserted into the at least one second mounting hole 33 correspondingly. Thereby the magnetic parts 4, 5 are fixed in the chambers 21, 31 respectively.
Before assembly of the first magnetic part 4 and the second magnetic part 5, the hooks 32 of the lower part 3 are located in the upper chamber 21. After completing the assembly of the first magnetic part 4 with the second magnetic part 5, the hooks 32 are located in the slot 23 between the protruding piece 22 and the first magnetic part 4. When lenses 6 are mounted in the eyeglass frame 1, the first magnetic part 4 and the second magnetic part 5 are attached to each other and mounted closely in the channel A of the bridge 11 so that the lenses 6 are firmly positioned within the left frame and the right frame 12, as shown in FIG. 3.
When users intend to change the lenses 6, the first and the second magnetic parts 4, 5 are pulled and separated so that the channel A is exposed, as shown in FIG. 4. The opening size of the channel A is defined by the distance between the hooks 32 in the upper chamber 21 and the protruding piece 22 so that the channel A will not be opened too much. Thus the lenses 6 can be replaced by new ones. Moreover, the opening size of the channel A is determined according to the position of the hooks 32 relative to the protruding piece 22. Thus the lenses 6 will not fall off in case of a collision. The lenses 6 are positioned by the channel A closed by the first and the second magnetic parts 4, 5 attached to each other while the lenses 6 are able to be replaced by the communicating channel A formed owing to the second magnetic parts 4, 5 pulled and separated. Therefore the lenses 6 are disassembled and assembled easily and conveniently.
