Abstract: An adjustable sun lounge for a performance or pleasure boat. The sun lounge converts from a seating configuration into a sunbathing configuration. The sun lounge generally includes a backrest which is movable via a double-pivot hinge and guided by a guide arm from an upright position to a substantially horizontal position. The sun lounge also includes a sunpad and a center cushion movable via a single-pivot hinge from an inclined position to a substantially horizontal position. When the backrest is in the substantially horizontal position and the center cushion is in the substantially horizontal position, the sun lounge is substantially horizontal and flat to accommodate a sunbathing person stretched out thereon. In the upright position, the backrest forms part of a seat structure which may be used when sunbathing is not desired, for example, while the boat is moving.

Abstract: An arrangement for interconnecting and supporting a pair of hexagonal building structures includes a pair of common support columns each having a hexagonal shaped connector tube mounted to an upper end thereof. Each connector tube includes apertures in each of the six lateral walls thereof which are adapted for receiving a nut and bolt combination for coupling the tube to the eave beams and roof trusses of two hexagonal building structures. The nut and bolt combinations are hidden from view within the connector tube and adjacent beams to provide a clean, attractive appearance and are not exposed to the elements. The use of common support columns and a common eave beam for adjacent hexagonal building structures simplifies assembly, reduces the number of structural components and building cost, and integrates two or more of such building structure for increased structural strength.

Abstract: A compound lever tool having a pair of interpivoted head levers with jaws and a toggle mechanism consisting of two actuating levers connected to each other by a toggle pivot and each connected to its respective head lever by a head pivot such that movement of the actuating levers towards each other spreads the rearward ends of the head levers apart and causes the jaws to close, the actuating levers each formed from sheet metal and bent to provide an upper and lower surface with each surface having aligned holes adapted to receive the toggle pivot and its respective head pivot. In the preferred embodiment the actuating levers are cloven to separate head pivot-supporting parts from the toggle pivot-supporting parts and adjustable blocks are disposed within the clefts to provide lateral support between the toggle pivot and the respective head pivots.

Abstract: A spreader tool having opposed force arms separately pivotally mounted on a base member for annular movement in opposite directions in response to axial movement of a driven piston of an associated jack wherein the inner edges of the force arms bear upon roller means mounted on the forward end of the piston. The curve of the inner edge of the force arms is preferably so constructed that the angle at which a constant axial force of the piston is applied to the force arm by the roller means is always such that the force applied to the load by the force arm is constant.

Abstract: A chain link tool including a pair of jaws on one side of the tool adapted to close the respective eyes of a cross chain connecting link, said jaws moving together as the handles are moved together and conversely, and such that a groove and a projection on the other side of the tool are adapted to receive the transverse portion of the side chain and to grasp the curved end of the cross-chain connecting link respectively when the handles are apart and to disengage the cross-chain connecting link as the handles are moved together.

Abstract: A structure for a hexagonal building has a novel steel frame including a connection which joins tension ring members, columns and roof trusses together with threaded fasteners. The upper ends of the rafters are joined by a tension ring. The bottom of each column is secured to a base by means of an adjustable base plate. Rafters spanning between the tension ring and compression ring are located between adjacent trusses. The frame is adapted to receive prefabricated sandwich-type panels for both roof and walls.

Abstract: A backing sheet or mat for use in the exposure of photosensitive materials under vacuum conditions, includes a sheet of porous, woven fabric having a nonreflective surface, a sheet of flexible, but substantially rigid, polymeric material beneath the fabric sheet, and a sheet of flexible rubber material beneath the polymeric sheet. Each of the sheets is attached together to form the backing sheet and a plurality of apertures extend through the thickness of the sheets of polymeric and rubber material and are arranged over substantially the entire area of the latter sheets.

Abstract: A ratchet cable cutter is provided with a double linkage between the handle and the pawl of the ratchet mechanism, and the relation between the two linkages is such that improved mechanical advantage is obtained while keeping the linkage mechanism within the limited spatial confines of the cutter tool.

Abstract: A prefabricated panel of substantially uniform width and thickness and having an interlocking feature comprises a foamed core slab, a rigid facing sheet bonded to the foamed core slab, and flange members integral with the facing sheet which interlock adjacent panels of the same type. Optionally, a heat-reflective liner is provided on the back side of the core slab.

Abstract: A structural panel material of the sandwich-type construction includes inner and outer facings and a core bonded between the facings. The core includes a plurality of blocks of lightweight core material, such as rigid or semi-rigid plastic foam, balsa wood, or a combination of plastic foam. These blocks are arranged in strips. The strips are joined together by corrugated sheet material. In a preferred embodiment, double-sided corrugated paperboard is used to join the lightweight structural strips. The resulting core material has the highly desirable characteristics of being flexible enough to conform to a mold shape under gravity and with the application of little or no external pressure so that special jigs are not required.

Abstract: A storage compartment for a collapsible boat canopy which folds to a horizontal position within the rear portion of the cockpit when not in use. The storage compartment is formed underneath the rear deck of the boat and has a forwardly facing opening closed by means of the rear passenger seat backrest, which is hingedly connected to the leading edge of the rear deck. The structural members for the canopy are supported within tracks on the cockpit side walls thereby permitting the entire canopy structure to be slid rearwardly so that the folded fabric portion is received within the storage compartment. The rear seat backrest is then swung downwardly over the opening and all but the vertical legs of the canopy structure is concealed. An upstanding ridge molded into the floor of the storage compartment serves to prevent the canopy from sliding forwardly.

Abstract: A roof structure for a building includes a number of panels, preferably of a sandwich construction with a rigid foam core and upper and lower surfaces which may be metal, wood or other material depending upon the use. A first type of joint extends along the fall line of the roof, with the panels being in side-by-side, spaced relation and supported along their ridges by a roof truss extending along this longitudinal joint. A retainer strip extends along the longitudinal joint and is held in sealing relation with the adjacent panels by means of threaded fasteners secured to the truss. A joint transverse of the fall line is formed by a tongue-in-groove construction of the panels which permits an upper panel to lap over a lower panel for better drainage, and also allows for thermal expansion and contraction.

Abstract: Insulating stud members comprising a foamed core having a sheet-form fastening member affixed to one surface and a thin moisture-impervious sheet affixed to the other surface and extending beyond the edges of the core to provide sealing flanges, and assemblies comprising a plurality of abutting insulating panels joined by the stud members, the panels each having a foamed core slab and a rigid facing sheet bonded to the core slab on one side thereof and a recess extending along the free edge of each of the adjacent core slabs, the recesses of adjacent panels cooperating to define a continuous open channel therebetween of dimensions just sufficient to receive a stud member so that the flanges thereof engage the surface of the insulating panels, fastening means extending through the insulating panels and having their ends embedded in the sheet-form fastening members of the stud members, and the sealing flanges being sealed to the surfaces of the insulating panels by means of a sealing material.
