Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to lighting fixtures and in particular, but
not restricted to, fixtures for mounting electric lights such as
Christmas lights on buildings.
2. Prior Art
It has become common practice to decorate homes during the
Christmas holiday season by attaching strings of lights to achieve
a decorative effect. The strings of lights are usually secured
beneath overhanding eaves and around gables, and are also
positioned to outline architectural features of the homes.
The strings of lights are usually secured in place by connectors
such as staples, which results, due to repetitive installation and
removal, in considerable marring of wooden surfaces. Long strings
of lights are difficult to install, consequently a householder is
often inclined to leave the lights in place once they are secured.
Although this avoids yearly installation and removal, the strings
of lights are exposed to weather for the full year resulting in
their early deterioration and, furthermore, they add nothing to,
and in fact detract from, the appearance of a house between
Christmas seasons.
Present methods of securing strings of lights as above mentioned,
furthermore often result in a hap-hazard disposition of the
lights.
Christmas light holders have heretofore been devised for attachment
to houses for presenting strings of Christmas lights in a regular
manner and which afford the lights some protection from rain, snow,
and the like. The lights, however, are always exposed to view,
consequently unless the householder is content to accept detraction
from the aesthetic qualities of his home the holders must be
installed and removed each Christmas season.
SUMMARY OF THE INVENTION
The present invention provides a lighting fixture unit which is
particularly adapted for permanently securing decorative lighting
to houses and other structures and enables lights to be moved
between hidden and exposed positions thus overcoming objections
above to permanent installation.
The lighting fixture unit of the present invention, furthermore,
protects electric lights and wiring from the elements and,
furthermore, is relatively inexpensive and simple to install and
operate.
The lighting fixture unit of the present invention includes a
housing adapted to be mounted on a building, the housing having an
opening, a door at the opening moveable between open and closed
positions, an electric light holder mounted within the housing for
movement between positions in which the lights are disposed in a
hidden position within the housing, and an exposed position
projecting through the opening.
A detailed description following, related to drawings, gives
exemplification of apparatus which, however, is capable of
expression in means other than those particularly described and
illustrated.

DETAILED DESCRIPTION
Fig. 1
fig. 1 shows a plurality of lighting fixture units, generally 10,
secured beneath an overhanging eave 11 and a gable 12 of a house 13
to outline a roof 14 of the house. The units, each of which houses
a string 15 of electric lights 15.1, are disposed in end to end
relationship, the string of lights in one unit being electrically
connected to strings of lights in adjacent units.
Figs. 2, 3, 4 and 5
The unit 10, see FIG. 2, has a sheet metal housing 21 which is
rectangular in section and which has a top wall 22, side walls 23
and 24, end walls 25 and 26, see FIGS. 2 and 3, and a bottom wall
27. The bottom wall has a width approximately one-half width of
that of the housing and extends from a lower edge of the side wall
24 to a free edge 27.1, see FIG. 5, so as to provide a
longitudinally extending opening 28 width of which is approximately
half the housing width. The end wall 25, see FIG. 5, has an
inwardly turned lip 26 defining one end of the opening 28. The end
wall 26 also has an inwardly turned lip, not shown, which defines
an opposite end of the opening 28. The free edge 27.1 of the bottom
wall and a lower edge of the side wall define sides of the
opening.
The unit includes a holder 31 to which light sockets 31.1 are
connected and a door 32 both of which have a hinged connection with
the bottom wall 27 at the edge 27.1 of the latter. The holder is a
strip of sheet metal, see FIGS. 3, 4 and 5, bent along one edge 33
to stiffen the strip longitudinally, and has a plurality of
uniformly spaced apart longitudinally aligned holes 34 for
receiving light sockets 31.1. A connector 37 having a collar 38
engaging a socket, and connecting straps 39 rivetted to the holder,
holds each socket in place. Electric lights 15.1 screwed onto the
sockets extend outwards of an outer face 42 of the holder.
The light holder is connected to the bottom wall in a piano hinge
arrangement, the edge 27.1 of the bottom wall and an edge 43 of the
light holder having rolled extensions 44 which form sleeves having
a rotatable fit on a longitudinally extending hinge pin 45. The
connection the the holder with the bottom wall enables the holder
to be swung between a position extending substantially normal to
the bottom wall as seen in FIG. 4 and a position extending across
the opening in which it rests on the lip 29 of the end wall 25 and
the corresponding lip of the end wall 26, see FIG. 3. The lights
can thus be disposed either in a hidden position within the
housing, FIG. 3, or an exposed position in which they extend
outwards of the opening beyond the bottom wall, FIGS. 4 and 5.
Wiring 46, see FIGS. 3 and 4, connects the sockets with a
three-conductor plug 47 secured to the end wall 25, and with a
three-conductor receptacle 48 secured to the end wall 26. The
receptacle and plug are grounded as seen at 49 to the housing, and
are disposed so that plugs of one unit engage receptacles of an
adjacent unit when the units are disposed in end to end
relationship as seen in FIG. 1.
The door 32 is also made of a strip of sheet metal and, as seen in
FIGS. 3, 4 and 5, is reversely bent along one edge 51 to a T-shape
to provide longitudinal stiffness, and has rolled extensions 52 at
an opposite edge for engagement with the hinge pin 45. The door
swings between a fully closed position, see FIG. 4, in which it
extends across the opening and a fully open position, FIG. 3, in
which it extends below and parallel to the bottom wall of the
housing. Spring clips 53-53.1 are secured to the side walls 23 and
24 of the housing for releasably engaging the edge 51 of the door
so as to maintain the door in either its fully open or fully closed
positions.
The unit includes a holder operator 55, see FIG. 5, mounted on the
hinge pin for effecting automatic movement of the light holder when
the door is swung between its fully closed and fully opened
positions.
The operator 55 has a sleeve 56 from which tabs 57, 58, 59 and 61
project laterally. The sleeve has a rotatable fit on the hinge pin
and the tabs are disposed so that with the door in its closed
position, see FIG. 4, tabs 57 and 58 extend upwards on opposite
sides of and effectively grasp the holder the tab 59 extends at
right angles to tabs 57 and 58 in engagement with an inner surface
of the door, while the tab 61 extends outwards of the housing at
right angles to the door. The door, when swung to its open
position, engages the tab 61 after swinging through an arc of
90.degree. thus rotating the operator so that the tab 57 swings the
holder to a position across the opening, see FIG. 5. The door, when
swung from its open position to its closed position meets the tab
61 after swinging through an arc of 90.degree. resulting in reverse
rotation of the operator so that the tab 58 swings the holder
upwards and away from the holder, the lights swinging to their
hidden position. The operator is formed from a single piece of
sheet steel which is thicker than the sheet metal forming the door
so that deflection of the tabs under load, is small.
Fig. 6
to facilitate movement of the door from its open to its closed
position a helical spring 62 having spring arms 62.1 and 62.2 can
be mounted under tension on the hinge pin with the arms reacting
against the bottom wall and the door for urging the door to swing
to a normal closed position. Provision of the spring is desirable
but not necessary. It is evident, and to be understood, that
provision of the operator, although desirable, also is not
necessary. The door and the light holder can be moved by hand,
independent of each other.
Fig. 7
fig. 7 shows a lighting fixture unit 70 which has an L-shaped
housing 71, one leg 72.1 of the housing being connectable to a
holder 75, similar to the holder 31, and carrying lights 76 is
mounted on a free edge 77.1 of the other leg 77 of the housing in a
piano hinge arrangement for swinging the lights between a hidden
position as shown in solid outline and an exposed position as shown
in broken outline. A tab 78 on the holder engages the leg 77
restraining swinging movement of the holder past the dotted outline
position.
OPERATION AND INSTALLATION
A string of units can be secured in end to end relationship beneath
the roof of a house so as to outline the gable or the eaves, the
units being secured to the house by screws which are extended
through suitable holes in the top wall 22. The units are disposed
in end to end relationship with plugs of each unit extending into
receptacles of a unit adjacent so that the strings of lights in the
units are electrically interconnected. Connection of strings of
lights of a pair of units can also be effected by a short length of
electric cable 63, see FIG. 1, having a plug receptacle for
connection with a receptacle and plug of said pair of units.
The housing and door of each of the units can be colored to match
the house trim. The under surface of the holder can be similarly
colored or can be reflectorized.
