  • Publication number: 20040221500
    Abstract: A picture frame system comprises a base, a flexible gooseneck extending from the base, a mount and a trim panel disposed at an end of the gooseneck away from the base. The gooseneck is a jointed, articulated tube with a resiliency sufficient to support a load defined by the mount, trim panel, and a picture. Optionally, a plurality of flexible goosenecks can extend from the base and each can have a different axial length. Also optionally, the mount and trim plate can be configured so that the trim panel is magnetically seatable on the mount for retaining the picture between the mount and the trim panel.

  • Publication number: 20040221501
    Abstract: A picture frame system comprises a base, a telescoping support coupled to and extending from the base, a mount and a trim panel supported at an end of the support away from the base. The support is comprised of at least first and second coaxially joined tubes. The second tube being axially moveable relative to the first tube. *The first and second tubes can be joined by one or more intermediate coaxially joined tubes. The support has sufficient rigidity to support a load defined by the mount, trim panel, and a picture. Optionally, a plurality of telescoping supports can be coupled to and extend from the base, and each can have a different axial length. Also optionally, the mount and trim plate can be configured so that the trim panel is magnetically seatable on the mount for retaining the picture between the mount and the trim panel.

  • Patent number: 6439748
    Abstract: An overhead lamp includes a base, a support post assembly, a bowl-shaped lamp shade, and a lamp unit. The support post assembly has an upper end, and a lower end that is fixed on the base. The bowl-shaped lamp shade includes an annular opaque peripheral shade member that is attached to the upper end of the support post assembly and that has an inner periphery and an outer periphery, and a light-permeable central shade member. The central shade member has an outer periphery that is attached to the inner periphery of the peripheral shade member. The outer periphery of the peripheral shade member defines an upper end opening of the lamp shade. The lamp unit is disposed within the lamp shade, and can illuminate surroundings of the overhead lamp via the upper end opening and the central shade member of the shade upon activation.

  • Patent number: 6203178
    Abstract: A lighting apparatus includes a support member, a lighting unit mounted on one end of the support member, and a lamp shade mounted on the lighting unit. The lighting unit includes a containment member having a mounting portion mounted on the support member, a flared wall portion extending from a periphery of the mounting portion in a first direction away from the support member, and a partition plate disposed inside the flared wall portion in a second direction transverse to the first direction so as to define a closed accommodating space and an open accommodating space on two sides of the partition plate. The partition plate is formed with a cord hole. A socket member is disposed in the open accommodating space for mounting a light bulb thereon. An insulated conductive cord member has a first end portion connected electrically to the socket member, and a second end portion that extends into the closed accommodating space via the cord hole in the partition plate.

  • Patent number: 6137210
    Abstract: A halogen lamp includes a bowl-shaped lamp housing, a light source, a reflector which has the light source mounted thereon and which is disposed on the lamp housing, and a heat insulating washer which is made of a heat insulating elastic material. The heat insulating washer is interposed between an upper end rim of the lamp housing and an upper end rim of the reflector in such a manner that the washer contacts the lamp housing and the reflector and that the lamp housing is spaced apart from the reflector, thereby minimizing heat transfer from the reflector to the lamp housing.

  • Patent number: 6062712
    Abstract: A lighting fitting for an incandescent lighting arrangement with a pair of incandescent bulbs, includes a lampshade body and a mounting bracket. The lampshade body is formed from molding plastics, and has an upper wall that defines a central through hole, and a skirt portion that extends downwardly and divergently from the periphery defining the upper wall. The mounting bracket includes an elongated middle portion which is formed with a mounting hole aligned with the through hole, and which has a distal wide surface and a proximate wide surface relative to the upper wall, and first and second end portions which are in line with and disposed at opposite ends of the middle portion. The first and second end portions are bent to an acute angle relative to and toward the distal wide surface of the middle portion along two parallel lines which incline at a predetermined angle relative to a vertical line that crosses a longitudinal direction of the middle portion so as to form first and second anchoring surfaces.

  • Patent number: 6004012
    Abstract: A light fitting includes a containment member, a mounting bracket, a pair of socket members, and a lampshade body. The containment member includes an upper body with a bottom wall, and an annular portion that extends divergently from the bottom wall. The bracket member includes a middle portion that has an elongate middle portion for securing to the bottom wall, and a bottom wide surface and a top wide surface, and first and second end portion which are disposed at opposite sides of the middle portion. The first and second end portions are bent respectively to an acute angle relative to and towards the bottom wide surface of the middle portion along two parallel lines which incline with a predetermined angle relative to a perpendicular line that crosses a longitudinal direction of the middle portion so as to form first and second anchoring surfaces, respectively. The socket members are mounted on the anchoring surfaces to receive a pair of incandescent bulbs.
