DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments.

(10) Referring to FIG. 1 to FIG. 4, an exploded diagram and three stereograms of the present invention are disclosed. An unilateral structure of a two-part glasses retainer of the prevent invention is disclosed, comprising:

(11) a temple cap (1), for embedding a temple (A) of a pair of glasses;

(12) a first strap (2) connected to the temple cap (1) at one end thereof;

(13) a valve seat (3) connected to the other end of the first strap (2) and comprises two wing portions (31) having a through hole (311) bored therein, a chamber (32) communicated with the through hole (311), and a regulation path (33) for communicating with a first open end of the chamber (32), wherein the chamber (32) and the regulation path (33) are formed between the two wing portions (31);

(14) a ball valve (4), embedded to the through hole (311) correspondingly and accommodated inside the chamber (32); and

(15) a second strap (5), connected to the ball valve (4) and passes through the regulation path (33), and moves inside the regulation path (33) through rotation of the ball valve (4) within the chamber (32).

(16) FIG. 2 is a stereogram showing the two-part glasses retainer in assembly according to the present invention. As shown in FIG. 3 and FIG. 4, the second strap (5) can be adjusted angularly through rotation of the ball valve (4) inside the valve seat (3).

(17) As shown in FIG. 1 to FIG. 7, the connection between the first strap (2) and the valve seat (3), and the connection between the ball valve (4) and the second strap (5) are presented in multiple types including direct forming, riveting, ejection molding, etc. For instance, an embodiment according to the present invention is disclosed as the following.

(18) The chamber (32) of the valve seat (3) is provided with a through groove (34) at a second end for accommodating the first strap (2), and the first strap (2) is provided with a first positioning element (21) at the other end to engage with and position in the through groove (34). The second strap (5) is passed through the regulation path (33) of the valve seat (3) and the through hole (311) of the wing portion (31) sequentially to engage with the ball valve (4). Moreover, the second strap (5) is further provided with a second positioning element (51) to engage with and position in an embedding hole (41) of the ball valve (4), allowing the ball valve (4) to be accommodated and positioned inside the chamber (32) by embedding in the through hole (311) of the wing portion (31). The embedding hole (41) is further provided with at least one block (42) at an open end of an inner edge to connect and limit the second positioning element (51).

(19) In use of the two-part glasses retainer of this invention, two temples (A) of a pair of glasses are embedded into the temple caps (1), and the straps are placed around a user's neck. Accordingly, the user can adjust angles of the straps according to his/her demands by pulling and moving the second strap (5) within the regulation path (33) so that the ball valve (4) is driven to rotate inside the chamber (32) correspondingly. Referring to FIG. 5 to FIG. 6, the ball valve (4) is further provided with a tangent plane (43), and the tangent plane (43) is correspondingly engaged with the regulation path (33) for positioning the ball valve (4) when the user alters the angles of the straps. A sectional view showing the second strap (5) in a state of downward displacement is also disclosed in FIG. 7.

(20) As shown in FIG. 8, the second strap (5) can be driven to rotate the ball valve (4) freely within the space of the regulation path (33) because the width of the regulation path (33) is wider than the diameter of the second strap (5) and is narrower than the diameter of the ball valve (4). Thus, the adjustable range and angle of the straps are increased, and the straps are protected.

(21) From the illustrations of the embodiments above, it can be known that this invention, compared with the conventional technologies available now, has the following advantages:

(22) 1. The design of the two straps of this invention is ergonomic and provides space flexibility for adjusting the straps.

(23) 2. The design of the ball valve rotated in the valve seat of this invention provides more flexibility to adjust the angle of the straps.

(24) 3. The design of the tangent plane of this invention provides a positioning function of the ball valve by correspondingly engaging the tangent plane with the regulation path.
