Abstract: A temple for a pair of eyeglasses with a longitudinal shaft and a temple end piece exhibits a telescoping connection between a first segment of the temple end piece and the shaft end facing this temple end piece. The connection further comprises a fixation device, which fixes or holds the shaft and end piece together. Either of the opposed walls of the telescoping connection are designed to be essentially cylindrical. Preferably, numerous ribs protrude radially from the other wall with the ribs running in the axial direction of the connection and finally holding the telescoping connection together. On account of this, the angle of the temple end piece with respect to the hinge on the temle shaft can be adjusted during assembly and then a connection is created between the temple end piece and the shaft which is resistant to rotational as well as pulling forces.

Abstract: An adjustable eyeglass temple is disclosed that provides fast and easy adjustment. The primary adjustment mechanism is a two piece telescoping temple that is adjusted by a screw within the temple. The screw is accessible from the front portion of the temple allowing the temple to be adjusted while the eyeglasses are being worn. It is also possible for glass wearers to make the adjustments by themselves, while wearing the glasses. Two types of removal caps are disclosed. These caps cover the access port to the adjusting screw. One cap mearly acts to conceal the screw, while the other cap is fitted with a plug that engages the screw slot, thereby allowing adjustment of the temple without removing the cap.Form fitting ear and nose pads are also disclosed. These pads will conform to the surface they contact, in the presence of body heat, and then set rigidly in the form fitting shape. Alternatively, oil-filled membranes can be substituted for the form fitting material.

Abstract: A temple for a spectacle frame has a plug connection between the shaft of the temple and temple end piece first made separately from the shaft of the temple. The plug connection is comprised of a borehole in one of the two elements and a plug on the other of the two elements, which plug is inserted into the borehole, as well as a fixing mechanism for ensuring the relative position between the temple end piece and the shaft. The fixing mechanism has a clamping element, which can assume various axial positions with respect to the peripheral wall surrounding the borehole and which, depending on its axial position, more or less sharply compresses the peripheral wall radially and through this means clamps the plug firmly in the borehole. This design of the fixing mechanism facilitates an exact setting of the length of the temple and of the inner inclination of the temple in adapting it to the geometry of the head of the individual spectacle wearer.
