  • Patent number: 10704750
    Abstract: Systems and methods for retrofitting an existing troffer light fixture, or for a new installation application, comprising a housing and a door assembly, wherein the door assembly comprises four side walls, a recessed cavity, a light source, one or more lens, and at least one support extension supporting the assembly are disclosed. The support extension may be a fixed horizontal protrusion of the frame of the retrofit assembly and configured to engage a T-bar of a ceiling system. The protrusion may rest on a horizontal portion of the T-bar to thereby support the assembly. Existing troffer light fixtures can be retrofitted to include a more efficient light source, replace components of a damaged troffer style light fixture, and/or otherwise upgrade or replace an existing fixture. The retrofit assembly may enable existing fixtures to be modified from a number of different fixture types without the need to remove and replace components of the existing fixture.

On the exterior of the structure, one of the stiles carries a plate that spans equal areas of both abutting stiles. The latch is symmetrically contoured, whereby observation from either side of the structure does not clarify the edge portion and direction of movement of such portion of the latch that is required in order to operate the latch and permit the sashes to be moved apart. Further, the exterior plate prevents insertion of a tool between the abutting stiles when the sashes are in closed position and latched.

    Abstract: A draw and pull latch consisting of a base plate for attachment to a cabinet, a body pivoted at one end on the base plate and normally covering the base plate, and a draw and pull nose pivoted on the body parallel to and spaced from the body-base plate pivot. The body carries a pivotal latching plate aligned with at least one latching hook on the base plate and urged by a torsion spring to a latching position. In the fully latched position the draw and pull nose pivot axis is above a plane through the body-base plate pivot axis and the keeper engagement by the draw and pull nose so that the latch will urge itself to a fully open position when the latch plate is disengaged from the latching hook.
