Glasses with quick-release lenses

Abstract

A pair of eyeglasses with quick-release lenses includes a frame, two lenses, and two temples. The frame includes two lens rings and two fasteners. Each lens ring has a ring body, a lower mating end wall connected to one end of the ring body, and an upper mating end wall connected to the other end of the ring body and detachably mated to the lower mating end wall. Each fastener is disposed on the lower mating end wall and the upper mating end wall of the corresponding lens ring and protrudes from at least one of the lower and upper mating end walls. Each lens is held by the corresponding lens ring and can be detached from the lens ring when the lower and upper mating end walls are separated. Each temple includes a front sleeve fitted onto the lower and upper mating end walls, the front sleeve being detachably fastened to the corresponding fastener.

7. Eyeglasses with quick-release lenses as described in claim 6, wherein, The top surface of the lower mating end wall and the lower fastener block together define a lower receiving groove for accommodating the upper fastener block, and the bottom surface of the upper mating end wall and the upper fastener block together define an upper receiving groove for accommodating the lower fastener block.

8. Eyeglasses with quick-release lenses as described in claim 4, wherein, The lower connecting end wall has a lower end wall connected to the ring body and a lower protruding arm extending rearward from the rear end of the lower end wall. The lower end wall and the lower protruding arm together define the lower buckle block. The upper connecting end wall has an upper end wall connected to the ring body and an upper protruding arm extending rearward from the rear end of the upper end wall. The upper end wall and the upper protruding arm together define the upper buckle block. Each buckle is disposed on the corresponding lower protruding arm and the corresponding upper protruding arm. The upper and lower ends of each buckle protrude from the bottom end of the corresponding lower protruding arm and the top end of the corresponding upper protruding arm, respectively. The front sleeve has a receiving space for accommodating the corresponding lower protruding arm and the corresponding upper protruding arm, a lower positioning hole communicating with the lower end of the receiving space, and an upper positioning hole communicating with the upper end of the receiving space. The upper positioning hole and the lower positioning hole can be detachably snapped onto the upper and lower ends of the corresponding buckle.

9. Eyeglasses with quick-release lenses as described in claim 8, wherein, The lower protruding arm has a lower through hole, and the upper protruding arm has an upper through hole communicating with the lower through hole. Each of the fasteners has a vertical cylindrical body, two positioning beads disposed in the vertical cylindrical body, and a compression spring disposed in the vertical cylindrical body. The vertical cylindrical body is fixedly inserted through one of the lower through hole and the upper through hole, and the vertical cylindrical body is detachably inserted through the other of the lower through hole and the upper through hole. The positioning beads partially protrude from the upper and lower ends of the vertical cylindrical body, and the positioning beads partially protrude from the bottom end of the corresponding lower protruding arm and the top end of the corresponding upper protruding arm.
