Hinge assembly and glasses frame

A hinge assembly, comprising:

• a guide body (30) comprising a first end surface (31) and a second end surface (32) provided at opposite sides respectively, the first end surface is provided with a first guide slot (33), the second end surface is provided with a second guide slot (34), and the first guide slot and the second guide slot intersect orthogonally;
• a first connection element (60), which is connected with a first spring (40) provided in an accommodation chamber (11) of an endpiece of a pair of glasses, and which is slidable telescopically in the axial direction of the accommodation chamber of the endpiece and has a first connection end (61) extending beyond an end surface of the endpiece;
• a second connection element (70), which is connected with a second spring (50) provided in an accommodation chamber of a temple end of a pair of glasses, and which is slidable telescopically in the axial direction of the accommodation chamber of the temple end and has a second connection end (71) extending beyond an end surface of the temple end;
• and
• comprising the first spring and the second spring;
• wherein the first connection end (61) and the second connection end (71) are hingedly connected and pivoted with each other in the guide body (30), the first connection end is pivotable along the first guide slot, the second connection end pivotable along the second guide slot;
• wherein, when being assembled to a pair of glasses, the first connection element is configured to compress the first spring provided in the accommodation chamber of the endpiece, and the second connection element is configured to compress the second spring provided in the accommodation chamber of the temple end, the spring force of the first spring acts on the endpiece such that the end surface of the endpiece abuts against the first end surface of the guide body, and the spring force of the second spring acts on the temple end such that the end face of the temple end abuts against the second end surface of the guide body.
