Abstract: This invention relates to an eyeglass frame comprising members, particularly hinge members, which are connected by a screw joint which is protected from becoming loose. The screw joint comprises a single metal part, which consists of a screw, which does not tend to become seized and to become clamped in the relatively movable hinge eyes. Because plastic parts are not required in the joint, the screw may remain installed during soldering work. This is accomplished in that the screw has a conical head portion which tapers with an included angle of 20 to 40 degrees, preferably 30.degree., and when the screw has been screwed into the frame the head of the screw extends in a conical opening in a member of the frame and in said opening defines with said frame member a clearance angle of 1 to 3 degrees and a clearance space axially adjoining the head. In such a joint the screw can firmly be tightened so that the high friction will prevent the screw from becoming loose spontaneously.

Abstract: In the case of a hinge for the connecting of a temple shaft with a hinge piece of a spectacle frame, at least one hinge eye is located on only one of these elements (the hinge piece or the shaft of the temple). The hinge pin running through this eye is designed in one piece with the other element (the shaft of the temple or the hinge piece). For this purpose, either the hinge pin of plastic is injection molded into the opening of the hinge eye or the hinge eye of plastic is injection molded around the hinge pin. In this case, one preferably proceeds in such a manner that one of the two elements with the associated hinge eye or hinge pin is formed first and that this initially formed element forms a part of the surface of the cavity of the injection molding tool for the other element such that the other element is injection-molded directly onto the initially produced element.

Abstract: A hinge connection for eyeglasses connects a lens frame to a temple piece with a threaded pin which does not loosen or fall out of the hinge even after repeated hinging movement of the temple piece. The hinge has a bore which is lined with an insert made of a material having cold flow characteristics. The liner has an untapped bore with a diameter slightly smaller than the major diameter of the pin. The pin has interrupted ferrule threads. When the pin is pushed into the bore of the liner, cold flow reformation of the bore locks the pin in place. The pin can be removed from the liner when desired by rotating the pin to cause its threads to form complementary helical thread in the bore wall and thereby thread its way out of the liner.

Abstract: The front part (1) of the spectacle frame carries a body (10) embedded in synthetic resin, the body containing a spring (14) and a ball (15) and having legs (11) to form a hinge part.
