Abstract: A frameless HVAC door system for reduced noise transmission leakage, and improved installation. The system includes a first member having opposed first and second surfaces and a first size that defines a first perimeter extending around the first and second surfaces. The first member is further equipped with a latch spaced apart from a hinge member on the first member. The door further includes a second member mounted on the first member first surface. The second member includes a sidewall extending around the second member to define a second member perimeter. The second member further includes a second member surface extending between the side walls and along the second member perimeter to define a compartment. The compartment is insulated against noise and temperature change. The second member perimeter is smaller than the first member perimeter, which defines a flange extending from the second member perimeter to the first member perimeter to define a flange perimeter.

Abstract: A port assembly for a marine vessel, including a lens element and three concentric stainless steel rings which are superimposed upon one another. A first of the rings includes a base portion forming an outer trim ring, a second portion which is generally parallel to the base portion and a sloping riser which defines an angle of between 105.degree. and 135.degree. with a base portion. The sloping riser also connects the base portion and the second portion. A second of the stainless steel stampings also includes a stepped cross-section with two risers and an intermediate portion connecting the two risers. The second of the risers also includes a sloped portion which is welded to the sloped portion of the sloped riser. A third stainless steel stamping, or clamping ring, is bolted to the intermediate portion of the second riser and, together with the base portion of the first ring, form a clamp for securing the port assembly to the wall of the vessel.

Abstract: A hatch assembly includes a first frame member having a generally J-shaped cross-section with a longitudinal extending or upright position and a generally parallel lip portion which is separated from the longitudinal portion by a horizontal section or riser. The assembly also includes a second frame member rotatably fixed to the first frame member. The second frame member includes a pair of elastomer seals fixed thereto so that a first of the seals engages the longitudinal portion of the J-shaped frame while the second seal engages the lip. The second frame member also includes a vent or small opening between the seals and a cavity for receiving any airborne water which passes through the vent. This vent is also constructed and arranged to drain air our of the cabin. In addition, the hatch assembly includes a hidden counterweight.

Abstract: A boat comprising a hull, a wall which is supported by the hull, which partially defines a space, and which has therein an opening affording access to the space, and a cover mounted on the wall for pivotal movement relative thereto about a pivot axis extending generally perpendicular to the wall, the cover being movable between an open position wherein the cover substantially uncovers the opening and a closed position wherein the cover substantially covers the opening.

Abstract: A portlight for installing at an opening in a wall of a boat, comprising an interior frame surrounding an open viewing area. The interior frame comprises an axially extending spigot for outward insertion in an opening in a wall of a boat and an interior flange extending radially outward from the spigot to overlap the interior face of the wall of the boat. An exterior frame surrounds an open viewing area. Plural fasteners fixedly clamp, between the interior flange and exterior flange, the rim of the opening in the wall of the boat. A pair of widely-spaced holes through the interior flange receive screw means for biting into the adjacent wall of the boat and thereby temporarily fix the interior flange on the wall of the boat to allow a single installer to place the exterior flange and install the plural fastener means and thereby clamp the exterior flange and interior flange on the rim of the opening in the wall of the boat.

Abstract: A hatch for a boat or other vehicle having a cover (10) that is pivotally connected to a frame (12) by a pair of releasable hing assemblies (32) that allow separation of the cover from the frame when the cover is forcibly opened against an object on an adjacent surface (14). A pair of pivotal handles (60) are restrained against movement into a downward angular position that would interfere with the proper closure of the cover.

Abstract: An integrally-formed portlight for installation through a sidewall opening in the cabin or hull structure of a marine vessel has an inwardly-projecting, rectangular spigot portion within which a rectangular light or screen can be selectively fitted. The light is hingingly supported along its top edge within the spigot to provide for upward opening to the inside for substitution of a rectangular screen, the screen being received, along an upper marginal edge portion, within the groove between the upper edge of the light, when withdrawn, and a peripheral shoulder formed within the spigot. Lower end portions of the light or screen are clamped in place against the peripheral shoulder of the spigot with use of elongated clamp-screws threadingly received in upstanding brackets secured to outer end portions of the spigot along the bottom wall thereof.

Abstract: A cast aluminum hatchway cover has projecting hinge structure for mating with a hinge housing part affixed on a hatchway coaming. The hinge is detented for holding the cover in closed, partly open and fully open posture. Self-latching lock structure has a foot operable unlocking lever outside the hatchway and an emergency unlocking lever inside the hatchway. The hinge detenting mechanism comprises cams with mating elements located respectively on the cover and hinge housing part.

Abstract: A marine capsule for sea rescue and transportation having a generally spherical configuration and on its sides hermetically closed hatches of tempered glass and a sun-reflecting signal-sending film. At its top are four larger diameter hatches, two of which preferably permit access of persons or equipment into the capsule. Also there may be waterproof lateral access windows or openings for persons without seafaring experience. The other two overhead hatches have a ventilation system, which admits air but not water. A stowable stabilizing element has members which can be telescoped by a gear and crank system so as not to interfere with handling of the capsule when not in use, but to extend when it is afloat. Radial fins ending in a peripheral fin protrude from the lower outside of the capsule, and an air chamber is built into its body. Other interior equipment includes a seat extending all around, storage compartments, water and toilet.

Abstract: A self-draining, leak-resistant boat window comprising a frame body having a continuous mounting flange for engagement with the hull of the boat, and a spigot wall connected with the flange and adapted to extend through an opening in the hull. A transparent molded plastic window pane is hingedly carried on the body; latches are provided to secure the pane in a closed position. The mounting flange has a peripheral groove into which a rib portion of an extruded, hollow sealing gasket is pressed. The rib portion has longitudinal barbs which frictionally engage the walls of the groove, thereby holding the gasket captive without cement. The gasket is oval in cross-section and is stretched an extent when installed on the window to thereby prevent buckling at the corners. When it is pressed between the flange and window pane it flattens a considerable amount by virtue of its oval shape, forming a tight seal.
