1. Technical Field
The present invention relates to hinges for spectacle frames, and more particularly, to an improved hinge structure of a spectacle frame.
2. Description of Related Art
Spectacles have long been the most popular vision correction tool, and stable wearing of spectacles relies on robust spectacle frames. We can see everywhere people use spectacle frames for myopia glasses, hyperopia glasses, presbyopia glasses and sunglasses to enhance vision or protect eyes.
In a typical spectacle frame, the temples and the frame body are connected through hinges that serve as joints. The existing hinge mainly uses a screw as its pivot, and such a screw, as a pivot, tends to loosen over repeated operation of the temple. When the screw loosens and is not timely screws to tight using a screwdriver, it can soon come off from the spectacle frame and get lost, making the spectacle frame unusable.
In view of the shortcomings of the prior arts, the inventor has used his years of experience to research and develop a hinge of a spectacle frame free from the problem of loosening screws and after numerous experiments and tries, an improved hinge structure without screws is well designed and herein disclosed.
The present invention discloses an improved hinge structure of a spectacle frame, which includes lugs formed at two sides of the spectacle frame, and an opening of each said lug is formed with a pendent insert that is configured to be inserted into a trough formed on a pivot. Then a fastening claw formed on the front end of a connecting member of each said temple can be used to grasp the pivot, thereby accomplishing the fabrication. Therein, the opening of the lug allows the fastening claw of the connecting member on the corresponding temple to move therein, so that the disclosed hinge structure can be rapidly assembled without using any screws and tools.
The invention as well as a preferred mode of use, further objectives and advantages thereof will be best understood by reference to the following detailed description of illustrative embodiments when read in conjunction with the accompanying drawings, wherein:
A spectacle frame 10 has lugs 20 at its two sides. The lug 20 has an opening 201 defined by a pendent insert 202.
A pivot 30, which may be structurally a polygonal column or a round column, has a trough 301 formed thereon for receiving and holding the pendent insert 202 of the lug 20 of the spectacle frame 10 in position.
In addition, each of two temples 40 has a front end formed with a plurality of resilient connecting members 401. Each of the connecting members 401 has its front end bent and formed as a fastening claw 402 for mating the adjacent contacting surface on the pivot 30.
In the temple 40, the connecting member 401 and the fastening claw 402 are each provided in at least two.
Additionally, the fastening claws 402 of different said connecting members 401 are bent toward different directions, so as to grasp the pivot 30 in different directions and also hold the pendent insert 202 of the lug 20 received in the trough 301 of the pivot 30 well, thereby holding the pendent insert 202 within the trough 301 of the pivot 30 in position. Also, the opening 201 of the lug 20 allows the fastening claws 402 of the connecting members 401 for the temple 40 to move therein, so that when the temple 40 swings, the connecting members 401 and the fastening claws 402 are driven to move. The resilient nature of the connecting members 401 and the fastening claws 402 then allows these components to deform according to the profile of the pivot 30 by slighting opening with respect to each other and restoring to hold the pivot 30 firmly, thereby forming a hinge structure this is assembled without using any screws and tools.
A pivot 30 may be a polygonal column or a round column (also referring to
In addition, each of two temples 40 has a front end formed with a plurality of resilient connecting members 401. Each of the connecting members 401 has its front end bent and formed as a fastening claw 402 for mating the adjacent contacting surface on the pivot 30.
In the temple 40, the connecting member 401 and the fastening claw 402 are each provided in at least two.
Additionally, the fastening claws 402 of different said connecting members 401 are bent toward different directions, so as to grasp the pivot 30 in different directions. When the temple 40 swings, the opening 50 defined by the hooks 20b of the arm 20a of the spectacle frame 10 and the pivot 30 allows the fastening claws 402 of the connecting members 401 to move therein.
The present invention has been described with reference to the preferred embodiments and it is understood that the embodiments are not intended to limit the scope of the present invention. Moreover, as the contents disclosed herein should be readily understood and can be implemented by a person skilled in the art, all equivalent changes or modifications which do not depart from the concept of the present invention should be encompassed by the appended claims.
