摘要： A strut (10) or strut system continuously adjustable in length for maintaining two bodies in a spaced relationship with respect to each other. Both the length of the strut (10) and the locking of the strut (10) at a desired length may be remotely controlled by pneumatic pressure. The strut system includes a cylindrical outer member (24) having a cylindrical bore for receiving a cylindrical inner member (22). The cylindrical inner member (22) is provided with a helical groove (42) for engagement with ball bearings (40) which are retained in a helical pattern in a collar (30) attached to the end of the cylindrical outer member (24) which receives the cylindrical inner member (22). The collar (30) is adjustable between a first position in which the ball bearings (40) are engaged in the helical groove (42) in the cylindrical inner member (22) and a second position in which they are disengaged from the helical groove (42) in the cylindrical inner member (22). When the ball bearings (40) are engaged in the helical groove (42) in the cylindrical inner member (22), the cylindrical inner and outer members (22,24) may be rotated with respect to each other to adjust the overall length of the strut (10). Further, the strut (10) will resist a compressing force applied to the opposite ends of the strut. When the collar (30) is in the second position with the ball bearings (40) disengaged from the helical groove (42) in the cylindrical inner member (22), the cylindrical inner and outer members (22,24) may be freely reciprocated with respect to each other. Pneumatic pressure may be used to adjust the collar (30) between the two positions, and to extend the cylindrical inner and outer members (22,24) with respect to each other.

摘要： A manual emergency tool assembly (10) including a pair of tools (12,14), each of which has an operating head and a handle (20). The handles (20,32) are formed to be telescopically engaged with each other. A locking arrangement is provided to secure the handles to each other in a fully telescoped relationship, and in intermediated telescoped relationships. A further locking arrangement provides for limited axial movement of the handles with respect to each other. The locking arrangement also provides for separating the tools (12,14) for independent use of each tool or for use of the tools together in a configuration other than with the handle in a telescopic relationship.
