Abstract: A cover for an end of a ladder rail includes a shell and a tread. The shell comprises at least one material, whereas the tread comprises at least one other material. The shell is sized to engage the ladder rail. The tread is engaged with the shell at least partially by at least one bond, which comprises at least a portion of the shell and at least a portion of the tread.

Abstract: A cover for an end of a ladder rail is provided. In one preferred form, the cover comprises a shell and a tread. The shell comprises at least one material, whereas the tread comprises at least one other material. The shell is sized to engage the ladder rail. The tread is engaged with the shell at least partially by at least one bond, which comprises at least a portion of the shell and at least a portion of the tread.

Abstract: A method for making a cover for an end of a ladder rail is provided. In one form, the method comprising the steps of: using at least one material to make a shell; using at least one other material to make a tread; and bonding at least a portion of the tread with at least a portion of the shell. Preferably, the shell and the tread are bonded to one another during the manufacturing process such that the shell and tread need not be mechanically fastened to one another in a separate and additional step.

Abstract: A support frame assembly including at least one pair of generally vertical spaced uprights joined together by transversely extending structural members and having caster wheel support members for supporting a rotatably mounted caster wheel mounted axle and a pedal actuatable lever engaging the axle to allow selective movement of the caster wheel mounted axle between "mobile" and "use" mode conditions--the invention further including a joined second pair of generally vertical spaced uprights each having a caster wheel support member for yieldably supporting a caster wheel arrangement for selective movement between "mobile" and "use" modes.

Abstract: A mobile ladder arrangement including base, ladder and linkage and caming assemblies therebetween to provide a foot actuated ladder assembly secured "use mode" and a hand actuated ladder assembly "mobile mode".

Abstract: A wear protection device for disposition between two relatively moveable members and particularly adapted for use for protecting rungs of extension ladders, the protection device being mountable on a ladder rung, the device including a fastener guide to enhance fixing and firmly gripping the device in place on the ladder rung.

Abstract: A collapsible-expansible support assembly including a support platform arranged to be supported by spaced ladder frames pivotally joined by a collapsible-expansible truss assembly, adapted to be restrained and automatically locked in shielded outward, expansible movement, the support assembly being mounted on a unique set of casters and plugs.

Abstract: A ladder wall stand-off accessory for mounting on a ladder rung between the spaced side rails of a ladder section including arm stand-off means with wall surface pad means extending therefrom and having rung gripping means pivotally mounted thereon to engage with the ladder rung to be fastened thereto in clamping relation therewith, a novel rung adapter bar being provided to mask the ladder rung if required.

Abstract: An assembly including several ladder sections positionable in several different ladder use positions, wherein intermeshable teeth elements can be cam locked selectively into such positions, and further including stabilizer bars at the ladder section ends for stable engagement with a supporting surface.

Abstract: Climbing apparatus including a rolling tower support platform, and method and tooling for the same wherein one of two spaced double walls of each of opposed tower rails of a tower ladder is snugly gripped by detents formed on the end portions of spaced rail rungs and the extremities of the rungs are flared, the rails including expanded bottoms for snap lock and threaded lock assembly with unique caster boxes of a caster wheel assembly for the tower rails and a support platform mounted on the rails with slidable carriages having double grip and threaded pin tightening arrangements and also having sockets to receive collapsible hand rail assemblies with unique hinges for gates thereof.

Abstract: A sofa bed mechanism for use on a foldable bed frame having a head section, an intermediate section, and a foot section, comprises a rear linkage assembly on a support member operable to control movement of the bed frame in between extended and folded sofa positions, a pivotal leg extending from each of the foot and intermediate sections, a front linkage assembly connected to the legs and to the rear linkage assembly for moving the legs into downwardly extending support positions in response to movement of the bed frame to the horizontal position and means extending between the front and rear linkages which maintains downwardly directed forces on the legs to prevent the folding of the bed frame from the horizontal position toward the folded sofa position in response to a downwardly directed load on the head section.

Abstract: In a sofa bed mechanism which includes a foldable bed frame, a support member on which the bed frame is movably supported, a linkage assembly operable to govern movement of the bed frame and a control member for guiding movement of the mechanism into and out of a storage position in a supporting framework.

Abstract: A sofa bed mechanism comprising a foldable bed frame having side and end rails and a back support slat extending between the side rails across the width of the bed frame at a position corresponding to the upper back area of a user in a sleeping position. The back support slat is bowed upwardly in its natural state and moves downwardly under load to yieldably resist the load and exert an outwardly directed force on the side rails. The slat has a top surface of substantial width so that it adds firmness to the bed without interfering with sleeper comfort. The invention further includes legs of semicircular cross section supporting the bed frame on the floor.
