摘要:
A self-powered illumination device includes an illumination source protruding from its lower surface for projecting light into a body of water to provide light that is emitted preferentially outwardly to illuminate the sides of a pool. Light emitted with an upward angle of inclination strikes the underside surface of the water-air interface surrounding the device and is reflected outwardly and laterally away the from the light source after striking such underside surface. Preferably, the illumination source has a length that extends downwardly that is commensurate or greater than its width and may be in the form of a fluorescent tube. The illumination device is fully self righting when inverted on the surface of a body of water.

A building structure with a tubular frame structure in a hut shape may be provided with cladding in the form of curved panels to provide a temporary or emergency shelter. These panels may consist of two spaced-apart plastic sheets fused together by parallel ribs serving as webs to provide parallel channels therein, e.g., Coroplast™-like sheeting. Such sheeting is preferably stiffening with one or more battens that are inserted through the hollow channels of the panel allowing them to be used as semi-rigid cladding over the entire building structure. The outer tubular members of the frame are all curved to improve rigidity. The frame includes channels for seating the panels as well as contribute to the structural integrity of the shelter.

A portable paint station that includes a work table and a pair of legs that are positionable in a retracted position and an extended position. In one form, the paint station provides a work surface that may be selectively positioned at two distinct heights. In another form, the paint station provides a work surface with a roller tray recess that may be selectively covered to resist the formation of a skin on paint that is located in the recess. In a further form, the paint station provides a work table with a pair of legs. At least one set of the legs has a handle aperture that may be employed to hand carry the paint station on its side. In yet another form, the paint station includes a roller tray assembly that facilitates the short-term storage of a paint roller that is loaded with paint.

An improvement in a check valve, especially a check valve intended to be mounted across a corresponding opening of a hydromassaging apparatus. The check valve comprises a casing having an inlet and an outlet, a conduit extending from said inlet to said outlet, structure for axially setting and fastening the check valve in a corresponding opening, and improved structure including a membrane and consisting of a flexible membrane made of elastomeric material and provided with an orifice, an element provided with a flap seat of sufficient size to completely cover the orifice, structure for connecting the element with the casing and positioning the seat in the vicinity of the outlet, and structure for fastening a periphery of the membrane across the outlet of the casing, to align the orifice with the seat and to position said orifice in such a way with respect to the seat that the elasticity of the membrane presses a portion thereof surrounding the orifice against the seat. When the pressure applied by the water of the tub plus the pressure resulting from the elasticity of the membrane that presses a portion of said membrane surrounding the orifice against the seat is higher or lower than the pressure of air on the opposite side of the membrane, the check valve is respectively closed or opened. The invention also relates to a hydromassaging apparatus equiped with such an improved check valve.
