Abstract
A light fixture including a housing having a longitudinal axis, an open axial end, and a lens door assembly pivotally connected to the housing and permitting the lens door assembly to move between an open position and a closed position. A latch mechanism secures the lens door assembly in the closed position over the open end of the housing. The latch mechanism can include at least one spring clip connected to the housing and engaging a tab of the lens door assembly when in the closed position.
Claims17
A light fixture, comprising:
- a housing having a longitudinal axis, and an open axial end;
- a lens door assembly including a lens mounted in a lens frame;
- hinge means for pivotally connecting the said door assembly to said housing and permitting said lens door assembly to move between an open position and a closed position;
- and
- latch means for securing the lens door assembly in the closed position over said open axial end of said housing, said latch means including a spring clip connected to said housing and engaging the lens door assembly when in the closed position, said spring clip including a first leg and a second leg, said first leg extending axially from the housing at an acute angle towards the longitudinal axis of the housing and being oriented to flex radially outwardly to receive and then engage the lens frame when the lens door assembly is in the closed position, said second leg being integral with the first leg and being fixedly connected to the housing perpendicularly with respect to the longitudinal axis of the housing, said first leg including an aperture, said lens frame including a radially outwardly extending tab which is received in and detachably engages the aperture of the first leg when the lens door assembly is in the closed position.

A light fixture, comprising:
- a housing having a longitudinal axis and an open axial end;
- a door assembly including a translucent member mounted in a frame;
- hinge means for pivotally connecting said door assembly to said housing and permitting said door assembly to move between an open position and a closed position;
- and
- latch means for securing said door assembly in the closed position over said open axial end of said housing, said latch means including a spring clip connected to said housing and releasably engaging said door assembly when in the closed position, said spring clip including a first leg extending axially outwardly from said housing at an acute angle towards said longitudinal axis in the closed position and being oriented to flex radially outwardly and thereby to receive and then engage said door assembly during closing, said first leg having a distal end portion acutely angled away from said longitudinal axis in the closed position, said distal end portion providing a cam surface which bears against said door assembly during closing, said latch means including mating detent means on said first leg of said spring clip and said door assembly, said detent means comprising an aperture and a tab to be received in said aperture in the closed position.

A light fixture, comprising:
- a housing having a longitudinal axis, an open axial end, an annular side wall and a flange integral with said annular side wall and disposed at said open axial end, said flange being substantially perpendicular to said longitudinal axis;
- a door assembly including a translucent member mounted in a frame;
- hinge means for pivotally connecting said door assembly to said housing and permitting said door assembly to move between an open position and a closed position;
- and
- latch means for securing said door assembly in the closed position over said open axial end of said housing, said latch means including a spring clip fixedly connected to said flange of said housing and releasably engaging said door assembly when in the closed position, said spring clip including a first leg extending axially outwardly from said housing at an acute angle towards said longitudinal axis and being oriented to flex radially outwardly and thereby to receive and then engage said door assembly during closing, said latch means including an aperture and a tab formed in and extending radially from said door assembly and said first leg of said spring clip, said tab being received in said aperture in the closed position.
