Abstract
The present invention provides a screwless eyeglass frame, comprising a rim support, a temple support and a a pivoting clip. The rim support comprises a first end face and an engagement slot recessed inwardly from the first end face. The temple support comprises a second end face, two extending walls extended outwardly from two corresponding sides of the second end face, respectively, and a shaft rod provided between the two extending walls. The pivoting clip comprises a C-shaped buckle with appropriate resilience, two connecting legs connected with two ends of the C-shaped buckle, respectively, and an opening located between the two connecting legs. In this case, the C-shaped buckle is allowed for pivotally connecting to the shaft rod. The two connecting legs are tenoned into the engagement slot, and the temple support is capable of rotating with respect to the rim support around the shaft rod and the C-shaped buckle.
Claims
1. A screwless eyeglass frame, comprising: a rim support comprising a first end face located at the end of said rim support, and an engagement slot recessed inwardly from said first end face; a temple support comprising a second end face located at the end of said temple support, two extending walls extended outwardly from two corresponding sides of said second end face, respectively, and a shaft rod provided between said two extending walls; and a pivoting clip comprising a C-shaped buckle having appropriate resilience, two connecting legs connected with two ends of said C-shaped buckle, respectively, and an opening located between said two connecting legs and communicated with the inner edge of said C-shaped buckle, wherein said C-shaped buckle is allowed for pivotally connecting to said shaft rod through said opening, said two connecting legs being operably in close proximity to each other so as to close said opening, said two connecting legs in close proximity to each other being just tenoned into said engagement slot, each of said extending walls being rested, at one side far away from said second end face, against said first end face, and said temple support being capable of rotating with respect to said rim support around said shaft rod and said C-shaped buckle.
2. The screwless eyeglass frame according to claim 1, wherein said rim support comprises a limiting block extended outwardly from said first end face, and each of said extending walls is rested at one side thereof against said limiting block when said rim support and said temple support are assembled.
3. The screwless eyeglass frame according to claim 1, wherein said first end face is presented as a plane face, while each of said extending walls is presented, at one side far away from said second end face, as a curved face.
4. The screwless eyeglass frame according to claim 1, wherein said first end face, and one side of each of said extending walls far away from said second end face are all presented as curved faces.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0016] Several preferred embodiments with regard to technical features and operating modes of this application will be disclosed hereinafter, in connection with the drawings, to be reviewed. However, these embodiments are illustrative for technical contents of the present invention only. Further, the drawings in the present invention are not necessarily to scale for convenience of illustration. The scale of the drawings should not be construed as limiting the scope of this disclosure.
[0017] Referring to
[0018] Specifically, referring to
[0019] Further, referring to
[0020] In this embodiment, the rim support 10 comprises a limiting block 13 extended outwardly from the first end face 11. Moreover, each of the extending walls 22 is rested, at one side far away from the second end face 21, against the limiting block 13, when the rim support 10 and the temple support 20 are assembled. In this embodiment, the limiting block 13 is equivalent in length to each of the extending walls 22. Consequently, the limiting block 13 is rested, at one side far away from the first end face 11, against an abutment 24 on the second end face 21, when the rim support 10 and the temple support 20 are assembled. Thereby, the rotatable angle of the temple support 20 is constrained. In this case, the first end face 11 is presented as a plane face, while each of the extending walls 22 is presented, at one side far away from the second end face 21, as a curved face, so as to facilitate smooth rotation of the temple support 20 with respect to the rim support 10. Also, in another embodiment, the first end face 11, and one side of each of the extending walls 22 far away from the second end face 21 are all presented as curved faces, just depending upon the requirement of the user.
[0021] To sum up, a mortise and tenon joint is adopted in the screwless eyeglass frame 100 of the present invention. The first end face 11 and the second end face 21 of the corresponding rim support 10/temple support 20, respectively, are mutually formed as slidable corresponding faces, so as to obtain the function of screwless fold. Furthermore, the whole structure does not rely on structural strain characteristic of metal, because no construction, such as fold line, hinge and etc., for example, is used for folding. Therefore, the screwless eyeglass frame of the present invention may be completely made from plastic, resulting in not only lighter weight of product, but also more competitive cost and recycling process than the conventional screwless eyeglass frame.
[0022] While this invention has been detailed described in connection with what is presently considered to be preferred embodiments, it should be understood that the invention is not limited to the disclosed embodiments. That is to say, various variations and modifications made in accordance with the patent claims should fall within the scope of the present invention.
