Provided are spectacle frames and a manufacturing method thereof, in which a front of the spectacle frames is formed by processing a celluloid plate of plastic, and temples are mounted on the front of the spectacle frames, thereby manufacturing the spectacle frames using the celluloid plate. The present invention does not require injection molding and an injection mold, and by processing both a hinge part and the front of the spectacle frames, the spectacle frames that can be applied to various wearers' face sizes can be manufactured with only the front of the frames having a single size. Also, by merely changing a design, various designs of the spectacle frames can be realized with only the front of the frames having a single size.

Es wird ein Brillengestell vorgeschlagen mit einem Brillengläser aufnehmenden Brillenrahmen (1, 16, 25), mit zwei Brillenbügeln (2, 22, 28) an dem Brillenrahmen (1, 16, 25), mit mindestens zwei elastisch verformbaren Streben (8, 9, 29, 30) jedes Brillenbügels (2, 22, 28) an seinem dem Brillenrahmen (1, 16, 25) zugewandten Ende, von denen mindestens eine Strebe (8, 9, 29) mit dem Brillenrahmen (1, 16, 25) verbunden ist, mit einer bei dem komplett montierten Brillengestell elastischen Verformung der Streben (8, 9, 29, 30) gegenüber einer entspannten, nicht montierten Stellung der Streben (8, 9, 29, 30) unter Ausbildung einer Wölbung der Brillenbügel (2, 22, 28) nach innen in Richtung des Brillenrahmens (1, 16, 25), mit einem Abstand der dem Brillenrahmen (1, 16, 25) zugewandten Enden der Streben (8, 9, 29, 30) bei dem komplett montierten Brillengestell, der kleiner ist als der Abstand dieser Enden der Streben (8, 9, 29, 30) in einer entspannten nicht montierten Stellung der Streben.

Apparatus comprising primary and auxiliary eyeglasses and further comprising:

a plurality of magnets mounted on said primary eyeglasses;

a plurality of magnets mounted on said auxiliary eyeglasses for mating beneath said plurality of magnets on said primary eyeglasses;

said plurality of magnets on said primary eyeglasses and said plurality of magnets on said auxiliary eyeglasses being oriented when mated such that the maximum magnetic attractive force between said magnets is oriented vertically parallel to lenses in said primary eyeglasses;

each of said plurality of magnets on said primary eyeglass being mounted in a universal adapter constructed to be mounted on said primary eyeglasses with existing hardware;



whereby said plurality of magnets on said auxiliary eyeglasses when mated beneath said plurality of magnets on said primary eyeglasses provides maximum resistance to downward movement of said auxiliary eyeglasses thereby preventing said auxiliary eyeglasses from detaching from said primary eyeglasses.

Bei einer scharnierlosen Brille, insbesondere Arbeitsschutzbrille, wobei die Bügel einstückig mit einem oberen Rahmenteil ausgebildet sind und an dem oberen Rahmenteil Befestigungseinrichtungen für die Scheibe ausgebildet sind, ist zum Erreichen einer kostengünstigen Herstellbarkeit vorgesehen, dass diese Befestigungseinrichtungen für die Schreibe (2) mit einem eigenelastischen oberen Rahmenteil (3) einstückig aus Kunststoff gespritzt sind.

A connecting device of the screw-and-nut type, comprising a block (11) with a nut thread, which is associated with a first element (13) and is suitable to be arranged in a through hole (14) provided on at least one second element (15) suitable to be fixed to the first element (13), and a threaded element (16), which is suitable to engage in the block (11) in order to lock the first element (13) to the at least one second element (15). The nut thread is constituted substantially by a cylindrical sector of thread (17) that opens onto the through hole (14). The threaded element therefore engages the cylindrical sector of thread (17) and the internal surface portion (18) of the through hole (14) that lies opposite the cylindrical sector of thread (17). The components described here of such a device can all be obtained easily by casting.

A spectacle frame being capable of replacing the front portion (1) as desired and being lightweight in comparison with the clip-on type and the flip-up type is provided. The spectacle frame includes the frame portion (2) attached with temples (13, 13) at both ends of the upper frame so as to be foldable and a front portion (1) having both lenses (4, 4). A bridge (9) provided at the center of the upper frame (8) of the frame portion (2) is formed with a fitting groove (10) opened upward, and a bridge (3) of the front portion (1) is formed so as to be fittable into the fitting groove (10). Provision of magnets on the bridge portion (3) and/or the fitting groove (10) further enhances connection between the front portion (1) and the frame portion (2).
