Application November 18, 1948, Serial No. 60,648

4 Claims.

The invention relates to light fixtures, particularly of the wall or ceiling recessed type wherein the fixture is provided with a flush wall opening normally covered by a translucent glass pane supported in place by a frame providing the wall trim of the fixture.

An object of the present invention is to provide a light fixture of the character described which is constructed to permit easy and rapid removal of the glass pane positioned across the wall opening so as to afford access to the interior of the fixture for removing lamps therein.

Another object of the invention is to provid a light fixture of the character above wherein the removal and insertion of the glass pane may be accomplished without the removal of screws, nuts or any other part of the fixture.

The invention possesses other'objectsand features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of the invention which is illustrated in the drawing accompanying and forming part of the specification. It is to be understood, however, that variations in the showing made by the said drawing and description may be adopted within the scope of the invention as set forth in the claims.

Referring to said drawing:

Figure l is a front elevation of a light fixture constructed in accordance with the present invention.

Figure 2 is a rear elevation of the fixture illustrated in Figure 1.

Figure 3 is a cross-sectional view of the fixture taken substantially on the plane of line 33 of Figure 1.

Figure 4 is a fragmentary perspectiveview of a portion of the fixture.

The light fixture of the present invention includes a fixture enclosure or housing 6 having an open endadapted for flush wall mounting and a face plate 1 providing the wall trip for the opening and coacting with the enclosure to provide a frame support for a pane 8 preferably of translucent material such as glass or other light conducting material. In accordance with the present invention and asone of the principal features thereof, to be presently more fully described, the frame is provided with one or more displaceable edge portions engageable exteriorly of the device to permit an enlargement of the frame. opening for removal or insertion of the pane.

The fixture may be designed to provide a light opening of any shape or size, but as here shown is designed to provide a light opening or rectan ular shape. As will be seen from the drawing, the enclosure 6 is a boxlike member having rectangularly related side walls 9, ll, l2 and [3 adapted for mounting within a wall or ceiling opening with one or more of such sides permanently secured to one or more wall timbers, such as studs, joists or the like. In the present construction, the side walls I l and I3 are provided at their front face with out-turned flanges l4 and I6 adapted for engagement against the exterior wall finish to provide a flush mounting of the open end of the enclosure in the wall. The other two sides,.9 and [2, are provided with in-turned flanges I"! and I8 which afford a securing means for the front plate I, the latter being detachably secured to these fianges and across the open front of the enclosure by means of screws [9 and 2|.

The front plate 1 is here formed with a rectangular shaped opening substantially aligned with the interior of the enclosure, but of a somewhat smaller dimension so that

perimetric edge portions

22 and 23, and 24 and 26, of the plate, bounding the opening therein, project internally from the side walls of the enclosure so as to provide internally projecting fianges at the open front of the enclosure.

In accordance with the present construction, the opening in the front plate I is further restricted by means of one or more displaceable members normally positioned at the perimeter of the opening so as to support and retain the pane 8 within the frame, but which are manually displaceable from the front of the device to enlarge the frame opening sufficiently to permit removal or insertion of the pane. In the present showing, a pair of

such members

21 and 28 are mounted along the

edge flanges

23 and 26. As here shown, these members are of flat, elongated form having a length sufficient to span the

opposite flanges

22 and 24 and are hinged adjacent a side edge 29 about a longitudinal axis, so as to swing inwardly into the enclosure. Normally, the strips 2'! and 28 lie upon the edge flanges in the plane of .the opening and project inwardly from the

opposite side flanges

23 and 26 so as to narrow the width of the opening. In the present construction, pivotal support for the members 21 and28 is afforded by hinge pins 3| and 32 which are journalled at the opposite ends in

clips

33 and 34, and 36 and 37, secured to the enclosure flanges H and I8. Attachment of the outer edges of the

members

21 and 28 to the pivot pins is here effected by crimping ears 38 and 39, and 4| and 42, on the members, around the pivot pins 31 and 32.

The pane 8 is provided with a perimetric form generally conforming to the shape of the frame opening but being somewhat larger than the opening, so as to engage at its edges and be supported by the edge flanges of the opening and the pivoted

members

21 and 28. Where the fixture is mounted in a ceiling, the pane will be supported in horizontal position and its weight, acting on the

pivoted strips

21 and 28, will hold the latter in their supported position in the plane of the opening. Since these strips project inwardly from the

edge flanges

23 and 26 of the front plate, a substantial portion of each of the strips is exposed at the under side of the front plate, as will be seen from Figure 1. When it is desired to re-. move the pane, the user presses upwardly against the exposed part of one or both of the strips 2';

and 28 so as to swing such strip upwardly and into the enclosure about the pivotal axis of the strip. This action, as will be clear, enlarges the extent of the frame opening and the pane 8 may thereupon be removed to afford access to the interior of the fixture, as for example when desired to change a light bulb or to clean the fixture, or thelike; Thereafter, the pane may be reinserted by again pressing one or both of the pivoted strips upwardly, so as to enlarge the opening sufficiently to admit the pane into the interior of the enclosure, and then lowering the strip to its opening restricting position, where it will serve'as a support for the adjacent edge of the pane.

In the present construction, the

displaceable strips

21 and 28 are so mounted as to automatically return to their frame defining position upon being released from an inwardly displaced, frame enlarging position. Such automatic return is provided. in the present construction by the 0dcenter pivoting of the strips adjacent their outer edgesso that the strips will automatically gravitate frorn'their raised, frame enlarging, position to their horizontal, frame defining, position. Also, if desired, this latter return of the strips maybeassisted by spring action. As here shown, the spacing of the hinge pins 3| and 32 from the

fixed flanges

23 and 26 is less than the spacing of. the. pins from the rear edges of the strip so that, onsw'inging the strips to their inwardly elevatedposition, the pins are resiliently bowed over their length between the clips 33 and Sd, thereby resiliently urging the returnof the strips to their horizontal position.
