GREENEIELD HIS ATTaR/Vfl 3,028,137 Patented Apr. 3, 1962 3,028,137 FLUSH MOUNTED LAMP FIXTURE Georges Houplain, 33 Rue des Fontaines, Sncy en-Brie, Seine-et-Oise, France Filed Dec. 1, 1958, Ser. No. 777,458 2 Claims. (Cl. 243-443) The present invention relates to a lamp holder, orientable or otherwise, embedded in the ceiling, used for obtaining lighting in which the light sources are concealed as much as possible.

It has more particularly the object of producing a holder comprising solid securing lugs affording an efficient hold in the ceiling and able to stand up to repeated dismounting.

Another object of the invention is to produce said securing lugs that can be removed from the lamp holder so as to reduce the space required or for storage and avoid risks of breakage during transportation.

The invention applies more particularly to the characteristics hereinafter described and to their various possible combinations.

An orientable lamp holder, for embedding, is shown by way of non-restrictive example in the attached drawings, in which:

FIGURE 1 shows a cut away View of the lamp support mounted in a ceiling;

FIGURE 2 shows a top plan view of the holding disk;

FIGURE 3 is a longitudinal sectional view of the securing lug;

FIGURE 4 shows a cross-sectional view of said lug;

11 FIGURE 5 shows a fragmentary sectional view of the C P;

FIGURE 6 shows a top plan view of said clip;

FIGURE 7 shows a longitudinal sectional view of the mounting of the lug on the clip;

FIGURE 8 shows a fragmentary top plan view of the mounting with the lug in cross-section.

The holder to be embedded shown in FIGURES 1 and 2 comprises more particularly:

A semi-spherical body 1 surmounted by a hoop holding the socket 2 into which the cap of the lamp 6 is screwed and resting on a truncated supporting base 3.

At its truncated part 3 said base 3 swivelably holds the semi-spherical body 1, thus enabling its orientation, and at its flat part 3 has a flange 3 for accommodating the clip 8 in which the securing lug 7 is mounted.

This arrangement enables the flange 3 to be perfectly applied to the ceiling 9 and to hold the base 3 by bending the securing lug 7 on the other side of the ceiling.

It is clearly understood that it is necessary to provide the base 3 with several clips 8 and lugs 7 in order that a perfect attachment takes place under the ceiling.

For a better understanding of the device, we hereinafter describe, by way of non-restrictive example, a lug 7 and its clip 8.

The lug 7 shown in FIGURES 3 and 4 comprises more particularly:

A vertical body 7 stifiened by two

flanges

7 and 7 more pronounced at the top part 7 than towards the bottom 79.

The top part of the body 7 will act as a pivot axis at the moment when it is required to bend the lug on to the ceiling. At this moment, the teeth 7 7 7 7 provided on each of the

flanges

7 and 7 will bite into the ceiling for efiecting a secure hold.

At its bottom part, the lug comprises a base 7 perpendicular to the body 7 drilled in the shape of a slot 7 The clip shown in FIGURES 5 and 6 comprises more particularly a tongue 8 perpendicular to the flange 8 fixed on two

bases

8 and 8 Between the two bases there is a T-shaped notch, whose two

internal shoulders

8 and 8 are formed to receive the lug portion 7 The mounting of the lug 7 in its clip 8 is clearly shown in FIGURES 7 and 8, in which can more particularly be seen:

The supporting base 3 includes the flat part 3 and the flange 3 to which the clip 8 is permanently attached by its bases 8 and 8., by soldering, riveting or the like.

The removable lug 7 is fixed in the clip 8 by means of its base 7 which is embedded between the two

bases

8 and 8 and under the

shoulders

8 and 8 of said clip 8.

To perfect rigidity, the tongue 8 of the clip engages in the slot 7 m of .the lug.

A thrust in the direction of the arrow F (FIGURE 7) will bendthe lug 7 above the ceiling 9 ensuring a rigid hold by inserting the teeth into said ceiling.

On the other hand, the base assembly 3 not being embedded in the ceiling, a crosswise movement of the lug 7 in the direction of the arrow P; will enable it to be easily removed by disengaging the base 7 and the slot 7 from the raised

shoulders

8 and 8 and the tongue 8 It is quite obvious that the invention is not restricted to the example of embodiment described and shown and from which several alternatives can be obtained.

In particular, the example of utilization has been taken with an orientable lamp holder for embedding, but it is quite obvious that it could be used with a non-orientable holder.

What I claim is:

1. In a flush mounting adapted to fit in the ceiling recess for a lamp including a supporting base, the improvement comprising an anchoring bracket having two legs of unequal length disposed at an angle to one another; the longer leg being stiifened by flanged edges, tapering and increasing in width from the vertex of said angle to the end of said longer leg to increase the resistance to bending near said end of said longer leg, said flanged edges having teeth formed thereon in the plane therewith, said longer leg being adapted to be bent around and above the edges of said recess in such a way that said teeth will bite into the edge of said recess and the upper surface of said ceiling; and the shorter leg being secured to the said supporting base by means of a tongue on said base passing through a slot in said longer leg adjacent said vertex of said angle.

2. Apparatus in accordance with claim 1 wherein said tongue comprises a projection from said base having two legs of approximately equal length at right angles to one another, one of said legs being perpendicular to the part of said supporting base from which it projects and the other leg, engaging said slot in said longer bracket leg, being parallel to said part of said supporting base.
