Abstract: A metal framing system for building structures wherein the members have continuously roll formed and fabricated "C"-shaped, "T"-shaped, and "I"-shaped cross sections and wherein the flanges at their distal edges excluding plate members, include a roll formed multi-purpose end and surface fastener recess extending the length of the member. These recesses are adapted to supportedly receive threaded fasteners for use in conjunction with both interconnection of pre-punched transverse plates at the ends of the members and also for attachment of wall covering against the flanges of the members. This recess and extended distal edge, while providing full functional flange width, also eliminates "Q" column flange loss while substantially stiffening the distal edge of the flange. "C" section studs and joists members may have two additional end fastener recesses added to the webs where a total of four fasteners are required per member for attachment to plates.

Abstract: A locking device for adjusting an angle or height of two parts of a seat comprises a housing, a rod slidable within the housing, a push rod with a spring to urge it forward, a spring cylinder, a cylindrical collet able to be compressed inwardly thereby engaging the spring cylinder with its cleaved portion, a cone fixed at the forward end of the push rod, moveable within the collet, a second spring biasing the cone, and drive means for driving the push rod along the housing. When the cone engages the collet by action of the second spring, the collet abuts the cylinder, thereby locking the rod and housing together. When the cone disengages from the collet, the collet is released from the spring cylinder by its own resilient force thereby releasing the rod from the housing.

Abstract: A portable shelter framework is formed by a series of end-interconnected modules, each defining a separate arch portion of the framework extending in different directions relative to each other. Each module is formed of elongate struts capable of being expanded into arched three dimensional form and collapsed into bundled form.

Abstract: A mattress supplement comprised of resilient material is substantially covered with support projections except for at least one marginal edge thereof. The marginal edge is adapted to compressively receive a sheet fitted thereto. The compression of the marginal edge permits the sheet to be secured to a mattress on which the mattress supplement is placed, instead of being pushed off thereof by the support projections.

Abstract: An access flooring system includes a plurality of adjustable height pedestals which support a skeletal grid of stringers. The stringers, in turn, support a plurality of rectangular floor panels. Each pedestal includes a head for supporting not only stringers which are registered with perpendicular edges of floor panels, but, in addition, stringers which extend diagonally. The diagonal stringers provide increased load capacity for the system and resist medial deflections of the panels.

Abstract: A power beam converts a linear force into a torque. The beam is slideably positioned transverse to a structural member to be rotated and adjacent a hinged connection of the structural member to a frame. The beam is driven in a linear direction by a motive means such as a hydraulic cylinder, cable network or threaded shaft and actuation nut. A cable extends from its connection to the structural member at a set distance from the hinged connection, over the end of the slideable beam and then to a bias means, typically a spring. To rotate the structural member, the slideable beam is driven transverse to the structural member to impart a force along the cable the spring travels to its limit and thereafter a significant force is applied to the structural member to rotate the structural member.

Abstract: This invention relates to a folding child's bed comprising a respective upper and lower frame, each being about horizontal and foldable. The frames are connected via diagonal struts which are variable with respect to their length, said diagonal struts being substantially parallel to each other and shortened when the child's bed is folded up. When the child's bed is used, they are obliquely disposed from the center portion of the upper frame to the outer portion of the lower frame and completely extended. To make handling of such a child's bed easier and, in particular, to make telescoping of the diagonal struts possible without any jamming, the diagonal struts comprise upper and lower struts disposed respectively in spaced and parallel relationship with each other and comprising at the joints thereof sliding guides which are provided on the struts and in which the struts are displaceably supported with respect to each other and are securable against displacement in the extended state.

Abstract: A post installation skylight assembly is presented in which a backup frame with an access opening is rested upon underlying secondary structural members prior to installation of a roof panel over and nesting with the backup frame, post removal of a medial position of the roof panel to expose the access opening, and positioning a translucent pane member over the opening frame to cover the access opening.

Abstract: A structure is proposed for metal constructions, in particular of the trestlework type, with at least an angle iron having equal legs, each one of which being extended at its free and with a first and a second extension length having a width substantially equal to half width of a leg, the first extension length being positioned at right angle relatively to the first extension length, the second extension length being positioned at right angle relatively to the first extension length, in such a direction as to depart from the other leg of the angle iron. The structure is moreover provided with jointing elements each constituted by a plate suitable to be fastened on to the angle iron at least in correspondence of the inner surface of one of its legs, and in correspondence of the inner surface of the second extension length of its second leg.

Abstract: A mechanism for coupling a strut (30) to a nodal element (32) comprises a female coupling fixture (31) and a male coupling fixture (33). The female coupling fixture (31) includes an elongate cylindrical member (35), a distal end of which is hemicylindrically configured with an inner surface that is contoured to receive a conjugately contoured knob on a distal end of the male coupling fixture (33) in mating engagement. The female coupling fixture (31) also includes a sleeve (36), which is slidable coaxially from an OPEN position around an intermediate portion of the cylindrical member (35) to a LOCKED position around the matingly engaged distal ends of the cylindrical member (35) and the male coupling fixture (33). Spring-biases locking bars (50) and (51) maintain the sleeve (36) in the LOCKED position.

Abstract: A pillow carried on a person's head to hold the head in a natural position. The pillow includes a back cushion held against the back of the head, and side cushions held against the sides of the head. The side cushions are hinged to the back cushion to hold the rear ends together, and straps are fixed to the front of the side cushions to hold the front ends together. A flap is fixed to the back cushion, and extends over the top of the head and is fixed to the straps to prevent downward movement of the pillow. The back cushion may have an extension shaped to support the cervical region of the backbone in its natural shape.

Abstract: An improved dock shelter comprising a pair of side panels and a top panel which are hinged to the dock and border a doorway in the dock. The panels are each biased to a storage position where the panel extends laterally outward from the dock. The panels are pivoted inwardly from the storage position to an operative sealing position by inflatable bags which are operably connected to the panels. A blower mounted above the doorway operates through a duct system to inflate the bags and pivot the panels into sealing engagement with the sides and top of a truck parked in front of the dock. When the loading operation is completed, operation of the blower is discontinued and the biasing mechanism acts to return the panels to the storage position. Corner panels are carried by the top panel and are mounted for flatwise sliding movement relative to the respective side panels.
