Patent number: 4739639Abstract: An auto-directing lever lock includes a case housing a cylinder (4) with a plug (3) mounted for movement therein. The plug includes a keyway (14) for accepting a key bit (7). A keyway opening (15) on the surface of the plug provides access for lever tumblers (6) to engage lever steps on the key bit. The key bit is detachable from a bow and shank section (8), and inserted in to the keyway through a key hole (39) in the case. The tumblers ride on a surface of the plug and are held away from the lever steps of the key bit during rotation of the plug, until the tumblers disengage the plug surface due to the keyway opening therein. The tumblers, when disengaged from the plug surface, fall onto the lever steps of the key bit to align gatings (32) of the tumblers so a bolt stump (28) may pass therethrough to retract a bolt (5) of the lock.Type: GrantFiled: September 25, 1986Date of Patent: April 26, 1988Inventor: Cathirgamathamby Balasingam

Patent number: 4735434Abstract: A toe piece for safety ski-bindings, which toe piece can pivot outwardly in a sideways direction against a biasing force if excessive lateral forces occur. A supporting member (8) is connected to two side holding members (9,10) adapted to support the sole of the boot in lateral and frontal directions. The support member (8) forms the coupling means of a linkage quadrangle which can pivot laterally. The side holding members (9,10) extend beyond the point where they are mounted to the support member. Each side holding member is releasably locked by means of a lever (27,28) mounted on the extensions thereof. A locking member (14) cooperative with the levers is adapted to release the appropriate side holding member when the linkage moves beyond a predetermined distance from center.Type: GrantFiled: May 2, 1986Date of Patent: April 5, 1988Assignee: Marker-Deutschland GmbHInventor: Gerhard Sedlmair
