Patent number: 5361850Abstract: The invention relates to a side strut (6) for the lower steering arm of a three-point hitch of a tractor. Locking catches (24, 25) are provided to cancel the floating position which the two telescopic members (14, 15) of the side strut 6 may assume relative to each other. The catches (24, 25) lock the members via locking contours (29, 30) of a locking recess 28, which surround and secure to a locking journal (31). The two locking catches (24, 25) are arranged at the sides of the telescopic members (14, 15). The locking catches have their pivot axis of the articulated journal (27) the points of contact between the locking contours (29, 30) and the locking journals (31), in a locked position, positioned on a connecting line. The line extends parallel to the sliding axis (16) and through the pivot axis of the ball eye (13). In this way, it is ensured that the locking catches (24, 25) and also the side strut (6), together, are not subject to any bending moments resulting from any tensile or compressive forces.Type: GrantFiled: June 5, 1992Date of Patent: November 8, 1994Assignee: Jean Walterscheid GmbHInventors: Norbert Muller, Ju Vollmer, Paul Herchenbach

Patent number: 4845905Abstract: A skylight, having a wing actuated by pneumatic springs, can be moved to an emergency opening position thereby substantially exposing the opening area of the skylight case. The skylight also acts as a residential ceiling or attic skylight which has, in the normal open position, a considerably smaller opening than in the emergency open position. A locking device is provided to restrict the long extension stroke of the piston rod of the pneumatic springs to a partial stroke. This partial stroke allows an opening which essentially corresponds to the standard opening of the wing in a residential skylight. The locking device, located on the cylinder of the pneumatic spring, includes a specially designed latch which, in order to effect partial stroke restriction of the piston rod, lockingly engages a stop located on the side of the case by means of a catch pin.Type: GrantFiled: May 31, 1988Date of Patent: July 11, 1989Assignee: Wilh.
