摘要

A safety device (28) on the frame (1) locks the slider (12) in the respective position by means of a safety element (20) whose slotted link (22) is traveled by a frame-mounted link pin (22,40) as the slider (12) swivels round axis (26) between the respective positions. The slotted link (22) has concentric sectors (24) and a bottom sector (28) plus a second sector (30). Sector (24) top end has a latching recess (34) and the sector (30) end furthest from the swivel axis (26) has a second latching recess (38) arranged so the recesses face one another. The safety element (20) is operated directly and can be released by an actuator fitted to the slider (12).
