A Shuttle type of aircraft (10) with an escape hatch (12) has an arcuately shaped pole housing (16) attachable to an interior wall and ceiling with its open end adjacent to the escape hatch. The pole housing 16 contains a telescopically arranged and arcuately shaped primary pole member (22) and extension pole member (23) which are guided by roller assemblies (30,35). The extension pole member (23) is slidable and extendable relative to the primary pole member (22). For actuation, a spring actuated system includes a spring (52) in the pole housing. A locking member (90) engages both pole members (22,23) through notch portions (85,86) in the pole members. The locking member selectively releases the extension pole member (23) and the primary pole member (22). An internal one-way clutch or anti-return mechanism prevents retraction of the extension pole member from an extended position. Shock absorbers (54)(150,152) are for absoring the energy of the springs. A manual backup deployment system is provided which includes a canted ring (104) biased by a spring member (108). A lever member (100) with a slot and pin connection (102) permits the mechanical manipulation of the canted ring to move the primary pole member. The ring (104) also prevents retraction of the main pole. The crew escape mechanism includes a magazine (60) and a number of lanyards (62), each lanyard being mounted by a roller loop (68) over the primary pole member (22). The strap on the roller loop has stitching for controlled release, a protection sheath (74) to prevent tangling and a hook member (69) for attachment to a crew harness.

In an aircraft having an escape hatch located relative to an aircraft protuberance so as to prevent a possibility of crew interference upon use the hatch, an escape device comprising: an elongated hollow pole housing with a closed end and an open end where said open end is located adjacent to an escape hatch; an elongated, hollow primary pole member telescopically disposed in said pole housing; an elongated hollow extension pole member telescopically disposed in said primary pole member; actuator means for moving said primary pole member and said extension pole member from a contracted position to an extended position; means for actuating said actuator means for moving said primary pole member and said extension pole member from a contracted position to an extended position; independent releasable slide members disposed on the open end of said pole housing for encircling said pole members and for selective sliding motion along said pole members when said pole members are in an extended position; and said pole members in an extended position having sufficient length for permitting release of one of said slide members from the terminal end of said pole members so as to prevent interference with said protuberance on said aircraft.
