Abstract: An inflatable cushion which can be alternately configured as a mattress or a chair. The cushion includes an inflatable elongate backing member having opposing ends and an inflatable pillow. To form a chair, the opposing ends of the backing member are coupled to form an enclosure which serves as the back and sides of a chair. The pillow is fit within the enclosure to serve as a chair seat. When the opposing ends of the backing member are uncoupled, the backing member is generally planar and forms a mattress. The pillow serves as a headrest.

Abstract: A device for movement over a viscuous or liquid medium, such as a water ski, has a textured contact surface which includes the bottom and side edges of the ski. The texture is formed of shallow dimples.

Abstract: A lift mechanism (15) for the cover (13) of a portable spa or hot tub (11) comprising a pair of compressible struts (21) and upper and lower hinge mechanisms (24 and 23) is disclosed. The preferred lower hinge mechanism (23) includes a torque tube (25) rotatably mounted through bushings (31) housed in plates (27). The plates (27) are located at a pair of adjacent lower corners of the spa or hot tub (11) and held down by the weight of the spa or hot tub (11). The struts (21) are attached to the ends of the torque tube (25). The other ends of the struts are attached to opposite sides of the spa cover by the upper hinge mechanisms (24), which preferably include brackets (33) that are fixed to the cover and pivot nuts (71) that rotatably attach the brackets (33) to the struts (21). When the cover is in its closed position, the struts (21) incline upwardly toward the center of the spa or hot tub (11). When the cover (13) is in its open position, the struts (21) lie substantially vertical.

Abstract: A water sports board (10) has a base (11) formed with rows of detent teeth (16) for locking engagement with the peripheral teeth (26) of binder plates (22), so that the binder plate may be angularly or longitudinally adjusted relative to the base. The board also has a pair of boots (21, 23) that are mounted to the binder plates and mounting assemblies for mounting the binder plates to the base.

Abstract: A spring chair has a seat frame and a base frame including an upper portion fixed to the seat frame, spaced front leg portions extending generally vertically down from said upper portions at the front of the seat portion, and base portions extending horizontally rearwardly from the leg portions to underlie the seat portion. The leg portions and base portions extend from a right angular bend portion and have lengthwisely extending openings. Unitary right angular springs inserted in the openings provide spring resilience to the bend portions which will restore them to normal position. The springs are preinserted in the linear extrusion strip which is bent to the base frame confuguration so that extrusion bending and spring bending occur simultaneously.

Abstract: A reaction injection molded recreation board with spaced rectangular reinforcing rods. The rods are rectangular in cross section and are disposed between upper and lower surfaces of the board. Position clips maintain the reinforcing rods in mutually spaced relationships within an injection mold during the process of injecting foam plastic. The structure of the positioning clips is also disclosed.

Abstract: An anodized aluminum sheet is prepared by applying an aqueous polyurethane 40 percent dispersion coating with a threaded roller having 20-1/32 inch deep triangular threads per inch. The coating is heated by graduated heating from about 125 degrees F. to about 240 degrees F. for about 20 minutes until the material is set and non-tacky. Thereafter, without special storage or handling requirements, the coated side of the anodized aluminum is bonded in a mold under reaction injection molding pressure to a reaction injection molding material.

Abstract: A swivel assembly comprising a base plate, a swivel plate mounted on the base plate for rotation relative thereto, bearing elements between the opposing inner faces of the plates, and a fastener connecting the plates. The fastener comprises a bolt having a head on the outer face of the base plate, and a threaded shank extending through axially aligned holes in the plates. The fastener further comprises a nut on the outer face of the swivel plate threaded on the bolt for drawing the swivel plate toward the base plate against the bearing elements. Both the head of the bolt and the nut are freely rotatable relative to the plates, with the head of the bolt being generally accessible for being turned, and the nut being rendered generally inaccessible by an object mounted on the outer face of the swivel plate.

Abstract: A unit for mounting a seat on a boat thwart or the like. The unit includes a base to rest on the thwart for securement thereto of the seat and a clamping assembly carried by the base for clamping the base on the thwart. This clamping assembly comprises a pair of arms extending outwardly from opposite sides of the base with each arm having a clamping shoe at its outer end. The shoes are engageable with opposite sides of the thwart for clamping the base to the thwart. The shoes are roughly adjusted quickly to space the shoes apart a distance somewhat greater than the width of the thwart for application of the unit to the thwart and then finely adjusted to draw them into clamping engagement with opposite sides of the thwart.

Abstract: An assembly for mounting an outboard motor on a boat, such as at the stern thereof. The assembly comprises an arm extending aft from the stern and having a block at its aft end for mounting the outboard motor at the stern, a guide for axially guiding the arm fore and aft of the boat, and a base on which the guide is removably mounted. The base may be mounted on the boat anywhere within a specified distance inboard of the stern, with the arm being adjustable fore and aft in the guide for mounting the motor at a predetermined position aft of the stern when the base is mounted at different distances (within the aforesaid specified distance) inboard of the stern.

Abstract: A latching assembly for mounting a seat on a boat thwart or the like comprising a base to rest on top of the thwart for securement of a seat thereto. A pair of keepers are mounted on top of the thwart for securing opposite sides of the base to the thwart, and a latch is mounted on the base on one of the opposite sides of the base. The latch is selectively movable from a retracted position to an extended latching position in which the latch projects beyond the side of the base and underlies one keeper to prevent vertical movement of the base relative to the thwart. The latch also abuts that keeper to block movement of the base on the thwart in side-to-side, front-to-back and back-to-front directions when the latch is in its latching position.

Abstract: A retractable babies' or children's chair is provided. The chair has a tubular frame slidably supported in tracks affixed to the underside of a table top. The frame, along with a seat and a back, can be slidably moved between a retracted position under the table top and an extended position protruding beyond the edge of the table to support a child in an eating position. The back is pivotally connected to the seat with the seat being pivotally connected by links to the tubular frame. The back has hooks which can be engaged with the frame to hold the back and the seat in a fixed position relative to the frame. When the frame is under the table top, the seat and the back are pivotally swung up to a position adjacent the frame so as not to interfere with knee room under the table. The frame has supporting clips which hold the seat in the adjacent position when under the table. The frame is equipped with safety catches which automatially hook over the edge of the table when in the extended position.
