Abstract
The length-adjustable spectacle temple includes at least two temple parts one of which is axially displaceable in a sleeve and is fixable in different positions. For this purpose, one of the temple parts is configured as a sleeve at least in one portion thereof. This sleeve has an axially extending slot for a latching slide adjustable axially in two positions. A spring element provided with a detent is disposed in the sleeve. A second temple part is so configured that it can be inserted in the first temple part. This second temple part has indexing recesses axially arranged on the insertable end and is configured to resiliently latch the detent. The latching slide completely covers the slot at least in the latched condition. The latching slide has a pressure body with which it latches the detent in a corresponding indexing recess in one of its two possible positions whereas the latching slide in its second position does not offer any resistance to movement of the two temple parts with respect to each other. A high degree of user satisfaction is provided with the spectacle temple since it makes possible an exchange of the insertable temple part and also permits a length displacement and a latching of the two temple parts to each other with relatively few components in a rapid and simple manner.
