3 Claims. 1

This invention relates to a bracket for mounting overhanging and outwardly extending floodlights and the like.

Frequently in outdoor installations, fioodlights are mounted on the roof of a building so as to overhang the parapet wall thereof or are mounted directly on the vertical wall of the building and project outwardly therefrom. In such installations the inaccessibility of the light fixtures, particularly where they are mounted relatively high above the ground and are spaced a considerable distance outwardly from the building, presents a difiicult and awkward servicing or maintenance problem.

Thus it is one of the objects of this invention to provide an improved bracket for a fioodlight and the like which facilitates servicing of the light fixture thereof even though the latter, when in normal illuminating position, is not readily accessible.

It is a further object of this invention to provide an improved bracket for a fioodlight and the like which is simple and compact in construction, yet provides adequate support for the fioodlight, and is easy to install.

It is a still further object of this invention to provide an improved bracket for floodlights and the like which employs numerous conventional or standard parts thereby minimizing the cost of manufacture.

Further and additional objects will appear from the description, accompanying drawings and appended claims.

In accordance with one embodiment of this invention, a bracket is provided comprising a base member having a pair of spaced transversely extending bearing sections. Rotatably mounted on the bearing sections and disposed therebetween is a hollow housing having a pair of apertured, axially-aligned trunnions journalled on the bearing sections. The housing is provided with a socket leading into the housing, the socket being disposed transversely with respect to the rotary axis of the housing and is disposed substantially centrally of the bearing sections. Means is mounted on one of the bearing sections and cooperates with the housing to effect locking thereof in one position of rotary adjustment.

For a more complete understanding of this invention reference should be made to the drawing wherein:

Figure 1 is a fragmentary perspective view showing a fioodlight mounted on the roof of a building and overhanging the parapet wall thereof;

Fig. 2 is a fragmentary perspective view showing a floodlight mounted directly on the vertical wall of a building;

Fig. 3 is an enlarged perspective view of the bracket; and

Fig. i is a fragmentary sectional view taken along line 1-4 of Fig. 3.

Referring now to the drawings, and more particularly to Fig. 1, a fioodlight IE1, adapted primarily for outdoor illumination, is shown mounted on the roof 5 l of a building with the light fixture i2 thereof overhanging and spaced outwardly from the parapet wall I3 of the building. The light fixture I2 is connected by a conduit l 4 which may be of standard or conventional construction to a bracket E5, the latter of which forms the subject matter of this invention. The length and size of the conduit it depends upon the particular installation.

The bracket comprises a base member it which is anchored by means of holding screws IT, or any other suitable means, directly to the roof H. Extending transversely from the base member It and attached thereto by welding, for example, is a pair of bearing plates or flanges l8 and 26 which are disposed in spaced parallel relation with respect to one another. Each of the bearing flanges l8 and 20 is provided with an opening 2!.

Rotatably mounted on the flanges l8 and 2B and disposed therebetween is a hollow housing or conduit box 22 which may be of conventional design. One side of the housing 22 is provided with a removable cover 23 so as to facilitate servicing within the housing of the electrical wiring 28 for the light fixture [2. The housing 22 is provided with a pair of axially disposed trunnions 2 2, each of which is provided with an internally threaded opening 25 which communicates with the interior of the housing. The trunnions 24 are journalled in the openings 2! formed in the bearing flanges l3 and 20.

Mounted transversely on one side of housing 22 and disposed centrally with respect to the bearing flanges l8 and 20 is a socket 26 having an internally threaded opening 21, which communicates with the interior of housing 22. Socket 26 is adapted to have threaded therein one end of conduit M.

The opening 25 formed in each of the trunnions 24 serve as means for enabling the wiring 28 for the light fixture E2 to be readily threaded into the housing 22 and out through the conduit is, as seen more clearly in Fig. 3. When several floodlights are connected in a series circuit, the wiring 28 may be inserted through one trunnion and out through the other. When the wiring 28 extends through only one of the trunnions, a plug, not shown, may be threaded into the other trunnion opening.

The bracket I5, as seen more clearly in Fig. 1, enables the fioodlight H] to be swung from its normal illuminating position A about the trunnions 2% as an axis to position B, as shown in dotted lines, when servicing of the light fixture I2 is required. If required, the conduit 14 may also be twisted or turned in socket 26' to move the fixture l2 closer to the-roof H in order to bring. it within the reach of the repairman. To effect pivoting or swinging of the fioodlight, a lock screw 3|, which extends through an opening 3!] formed in either flange H3 or 20, is withdrawnfrom a threaded opening 32 formed in the nous-- ing 22 (Fig. 4). When the. screw 3| is threaded into opening 32, the housing ZZ'is held in arelatively fixed position with respect to the bearing flanges [8 or 29. The relative disposition of the lock screw 3|. on flange l8 dependsupon the desired relatively fixed position of housing 2.2 with respect to the basemember 16..

Fig. 2 shows the bracket l-used in mounting a light fixture I2 directly on a vertical. wall 33. The light fixture l2 ishe-ld inspaced relation with. respect to the vertical. wall 33, by an. elongated arm or conduit 34 which,. inthis instance, is substantially straight. Whenthe. length of conduit 34 is of. considerable extent, a brace 35 may be used which has one end. thereof mounted directly on the wall 33andhas the other end connected toa strap 36 which embraces conduit 34.

The problem of servicing the light fixture l2, particularly whenit is mountedat a considerable hei ht above the ground and the conduit 34 is of considerable length is readily apparent. To efiect servicing of the. fixture. [2" in such an instance, as seen in Fig. 2,.the l'ock pin or screw 3| is withdrawn fromthe housing 22. and the brace 35 is disengaged from. the. strap 36, whereupon the fioodlight may. be. pivoted or. swung about the trunnions. 24. as anaxis until the light fixture I2 is ad acent the vertical wall 33, whereupon the repairman may readily service the fixture while he is standing on a ladder or scafiold positioned against the wall.

By having the electrical wiring or leads 28 for the light. fixture l2. introduced axially into the housing 22, the problem of the wiring twisting or bending,.when the housing is pivoted, has been overcome.

While the bracket in. this instance is shown used. in combination with a. floodli ht', it is to be understood that it is not to be limited to such use butmay be adapted for use in supporting a flagpole and the like;

Thus, it will. be seen that a bracket has been provided for mounting afloodlight, particularly in outdoor installations which enables the floodlight to be readily servicedwhen required, even though the, light. fixture, when in. normal illuminating position is. inaccessible. Furthermore, the bracket is simple in construction, yet provides adequate support forthe fioodlight and may employ numerous conventional or standard parts thereby minimizingthe costof manufacture.

Whileaparticular embodiment of this invention is shown above, itwill be understood, of course, that the inventionis not to be limited thereto, since many modifications may be made, and it is contemplated, therefore, by the appended claims, to cover. any such modifications as fall within the true. spirit and scope. of. this invention.
