Abstract
A linear motion unit (10) includes a runner (14) that is arranged so as to be movable along a rod (12). Provided in front of and/or behind the runner (14) are support units (20) that support the rod (12) relative to a counter-element (18). Provided on the runner (14) and the support units (20) are catches (28) that in each case can be brought into latched engagement with the adjacent support unit (20). The support units (20) are each comprised of a base body (22) upon which is movably mounted a control element (24). The control element (24) can be moved between at least one latched position and at least one released position by means of a control track (30). In accordance with the invention, the control element (24) has at least one control recess (24b). Furthermore, the control track (30) includes at least one control projection (34e) that is arranged at an angle to the direction of motion (L), so that when the support unit (20) moves in the direction of motion (L), the control projection (34e) moves the control element (24) essentially perpendicular to both the direction of motion (L) and the direction of extension of the recess.
