point opposite said track.
5. A recessed lighting fixture according to claim 3 wherein a
flange is provided at the open end of said housing, a plurality of
annularly spaced fastening means are mounted on and extend from the
outer surface of said flange, said closure being mounted flush
against said flange and within a circular area defined by fastening
means, an escutcheon plate overlying said fastening means and
having a plurality of openings aligned with said fastening means,
and means extending through said openings and engaging said
fastening means to secure the escutcheon plate to and in spaced
relationship with said flange whereby said closure is rotatably
retained between said flange and escutcheon plate.
6. A recessed lighting fixture according to claim 2 wherein said
clip further comprises a spring finger mounted thereon and bearing
against said track.
7. A recessed lighting fixture comprising a cylindrical single
open-ended housing having an outwardly extending flange at said
open end, a closure plate having an opening therein and an upwardly
extending cylindrical member secured thereto, said cylindrical
member slidably engaging said housing with said plate lying against
said flange, an arcuate track secured at one end to the edge of
said opening and extending upwardly therefrom, track supporting
means secured at one end to said closure plate and at the other end
of said track, a lamp assembly including a lamp housing having a
lamp socket mounted therein, means hinging one end of said lamp
housing to the edge of said opening opposite said track, a spring
clip carried at the upper end of said lamp housing and slidably
engaging said track and means including an escutcheon plate
removably secured to said housing flange and rotatably securing
said closure to said housing.
Description
This invention relates to lighting fixtures and more particularly
to a recessed lighting fixture having a movable lamp assembly
therein.
Recessed lighting fixtures embodying lamp assemblies arranged for
movement relative to the housing to shift both the direction and
angle of the emitted light have been suggested, but such structures
are relatively complicated and expensive and, in many instances,
provide only limited lamp adjustment. This invention overcomes the
foregoing difficulties and provides a novel and improved recessed
lighting fixture affording a vertical angular adjustment of the
order of 90.degree. and a horizontal directional adjustment of the
order of 360.degree.. This is attained by an improved arrangement
and organization of elements which provides a simplified structure
which is easy to adjust and maintain, and which can be fabricated
at a relatively low cost.
Another object of the invention resides in the provision of a novel
and improved recessed lighting fixture wherein the angle and
direction of the emitted light can be adjusted over relative wide
ranges.
The above and other objects and advantages will become more
apparent from the following description and accompanying drawings
forming part of this application.
In the Drawings:
FIG. 1 is an exploded perspective view of the lighting fixture in
accordance with the invention,
FIG. 2 is a cross-sectional view of FIG. 4 taken along the line
2--2 thereof,
FIG. 3 is a bottom view of the assembled fixture shown in FIG.
1,
FIG. 4 is a cross-sectional view of FIG. 2 taken along the line
4--4 thereof,
FIG. 5 is a left-hand elevational view of FIG. 4 with portions
broken away, and
FIG. 6 is a perspective view of a clip for slidably engaging a
curved track and controlling the angular position of the lamp
assembly relative to the housing.
Referring now to the drawings, the recessed fixture generally
denoted by the numeral 10 includes a single open-ended cylindrical
housing 12 having an outwardly extending flange 13 about the open
end thereof. The housing also includes slotted openings 14 for
mounting the fixture to a conventional plaster ring now shown since
the installation of recessed fixtures is well known in the art. The
flange 13 includes a plurality of internally threaded bushings 15
extending from the bottom surface of the flange.
The bottom closure plate and lamp assembly support structure is
generally denoted by the numeral 16 and it is held in position on
the fixture by an escutcheon plate 17. The closure plate includes a
ring 18 having a short cylindrical portion 19 slidably engaging the
inside of housing 12 and an outwardly extending flange 20 having a
diameter slightly smaller than the diameter defined by the bushings
15 so that the flange 20 will ride against the housing flange 13. A
plate 21 underlies and is secured to the flange 20 and has a
pear-shaped opening 22 therein to permit the lamp assembly 23 to be
moved into and out of the housing 12 as will be described.
The lamp assembly supporting means carried by the closure plate 16
includes a vertically disposed curved track 24 secured at its lower
end to the narrow portion of opening 22 and at its upper portion to
an upright member 25 fixed at its lower end to the cylindrical
portion 19. A hinge 26 is secured to the plate 21 at the base of
member 25 as will be observed more clearly in FIG. 4.
The closure plate 16 is held in position by the escutcheon 17 which
has screw receiving openings coordinated with the bushings 15. When
screws 28 are inserted through openings 27 and engage bushings 15,
the closure plate is rotatably held in place since the depth of
bushings 15 is slightly greater than the combined thickness of
flange 20 and plate 21.
The lamp assembly 23, as will be seen more clearly in FIG. 4,
includes a generally conical lamp housing 29 secured at the bottom
edge to hinge 26 and carries a bracket or spring clip 30 at its
apex. The clip 30 has a shank 31 attached by means of an opening 32
and screw 33 to the lamp housing 29. The screw 33 may also engage
and secure the lamp socket 34 in place in the lamp housing. The
clip 30 has a pair of ears 35 bent about and slidably engaging
track 29, and a spring 36 bears against the underside of track 29
to provide sufficient friction to hold the lamp housing 29 in any
adjusted position. A flexible electric cable 37 is connected to the
socket 34 and emerges from the lamp housing 29 through an opening
38. The cable then extends through an electrical connector 39 in
housing 12 for connection to a suitable supply. Adequate slack is
provided in the cable to permit movement of the lamp assembly 23 as
will be described.
With the structure as described above, the lamp assembly 23 can be
positioned wholly within the housing 12 as shown in full lines in
FIG. 4 so that conventional down lighting is provided. The angular
position of the lamp assembly can be adjusted simply by grasping
the tab 40 on the side of the lamp housing 29 and pulling it
downwardly. This causes the lamp assembly to move about the hinge
pivot 42 and the spring clip 30 will hold the lamp assembly in any
adjusted position including the outermost position shown in the
dotted outline in FIG. 4. At the same time, the lamp assembly 23
can be rotated relative to the housing 12. Stop means 41 carried by
the housing 12 limits rotation of the lamp assembly to avoid damage
to the cable 37.
While only one embodiment of the invention has been illustrated and
described, it is apparent that alterations, modifications and
changes may be made without departing from the true scope and
spirit thereof as defined by the appended claims.
