  • Patent number: 7832901
    Abstract: A beam adjustment mechanism for a light fixture includes a frame assembly having an aperture substantially within the center thereof. Multiple peripheral lighting units engage the sides of the frame assembly. Each lighting unit includes an LED, a heat sink, and a reflector member. A central connecting member and/or a central lighting unit is at least partially surrounded by the peripheral lighting units. The central connecting member and/or central lighting unit is hingedly connected to at least one of the peripheral lighting units. An adjustment shaft extends through and is moveably engaged with the aperture of the frame assembly. Movement of the adjustment shaft relative to the aperture exerts a force on the central connecting member and/or central lighting unit, which causes the hingedly connected peripheral lighting units to pivot relative to the central connecting member and/or central lighting unit.

  • Patent number: 4674136
    Abstract: A safety mask construction comprises a substantially rigid face portion which is receivable over a portion of the face of a wearer and a pair of substantially rigid arm portions which extend rearwardly and inwardly from opposite sides of the face portion for engagement with the rear and upper rear portions of the head of the wearer. The arm portions are preferably hingeably attached to the face portion and biased toward inwardly hinged positions so that when the safety mask is mounted on the head of the wearer, they resiliently embrace the head to retain the face portion in proper orientation thereon.

  • Patent number: 4457402
    Abstract: A wheelchair lift operable to transport handicapped persons between a lower level and an upper level. The apparatus includes an elevator platform and a plurality of vertically movable stair members. When the platform is in its lower position, the stair members form a conventional stairway which extends between lower and upper surfaces; and when the platform is moved upwardly, a collecting member attached thereto sequentially collects the stair members and moves them upwardly until the platform and stair members are coplanar with the upper surface. A normally open safety gate on the platform is automatically moved to and retained in a closed position whenever the platform is raised above the lower surface.
