ABSTRACT:
A concealable lighting fixture wherein the longer, vertically extending leg of a support frame is mounted in a vertically extending bearing in a bracket so that the frame is vertically shiftable in and rotatable with respect to the bracket. A diametrically extending support pin is mounted in the lower end of the longer leg for engaging a support surface on the upper end of the bracket. When engaged with the support surface, the support pin releasably retains the frame, and a lamp assembly on the upper end of the support frame, in an elevated operative position. In one embodiment, the bearing for the longer leg of the frame is provided by concave recesses in the inner faces of a pair of vertically extending flanges on one side of the plate portion of the bracket. In another embodiment, the bearing is provided by a tube welded to the plate portion. A vertical slot in the bearing prevents the support frame from being shifted between its raised and lowered position except when at least one of the ends of the support pin is aligned with the slot. A plurality of vertically spaced guide pins in the longer leg of the frame prevent rotation of the frame as it is being raised or lowered. The lamp assembly includes a shade support member that is pivotally connected to the outer end of a horizontally extending section at the upper end of the support frame, and pins in the inner ends of a pair of horizontally extending tubular shades prevent disengagement of the shades from the shade support member when the pins are engaged in slots in the outer ends of the shade support member.
