12 claims.
This invention relates-to a light fixture and
switch assembly for cabinet structures, and more
particularly to such a iixture and switch assembly»
for illuminating the interior of cabinet structures
ci the kind employed in refrigerators or the like.
It is an object of our invention to provide an
improved light fixture and switch assembly com»
posed of several parts wherein one part can be
secured in position during the fabrication of the
10 cabinet structure and thereafter the remaining
parts can readily be inserted into position to
form a complete light and switch assembly.
The invention, together with the objects and
advantages thereof, will become apparent from
15 the following description taken in conjunction
with the accompanying drawing forminga part
of this speciñcation, and of which Fig. 1 is a
fragmentary front view of a refrigerator em
bodying our invention; Fig. 2 is an enlarged sec
tional view taken _on line 2-2 of Fig. 1 to illus
trate the light fixture and switch assembly more
clearly; Fig. 3 is a sectional view taken on line
3-3 of Fig. 2; and Fig. 4 is a sectional view
taken on line 4_4 of Fig. 3.

Referring to Fig. 1», we have shown our inven
tion in connection with a refrigerator cabinet I0
having a storage compartment II into which
access may be had by a door I2 hinged to the
front of the cabinet. 'Within the storage com
30 partment II is arranged a cooling element I4
comprising a metal shell adapted to receive ice
trays I5 and adjacent to or about which may be
-arranged an evaporator coil (not shown) of re
frigeration apparatus for producing cold in a well
known manner.
`
`
(ci. 24o-4)
I6 for automatically illuminating the interior of
the storage compartment II when the door I2 .
is open. 'The light ñxture and switch vassembly
comprise a hollow electrical connecting block
or casing 2I having a removable cover plate 22, 5
the block and cover being formed of suitable in
sulating material and L-shaped, as shown in Fig.
4. The block 2I‘ is provided with an opening in a ,
side wall thereof to receive a conductor 23 which
is adapted to be connected to a suitable source
of electrical energy. The conductor 23 is adapted
to be .connected to screws 24 positioned adjacent
the opening. In one of the arms of the block
2I are arranged two thin strips 25 of electrically
conductive material which are bowed inwardly
from a point intermediate their ends. The strips
25 are disposed in spaced vertical planes and
the lower edges at the extreme outer ends thereof
are ñared outward, as indicated at 26, to form
two spring clips adjacent two openings or slots 20.
in the bottom of the block 2|. The outer ends
of the strips 25 are maintained in alignment
with the slots at the bottom of the block by '
an insulating stud 21 which -extends upward
from the bottom of the block adjacent the open
ings and between the strips, and an upward ex
tending insulating stud 28 and protuberance 29
which bear against strips 25 at a point spaced
from the stud 21.
_
In the other arm of the block 2| are arranged
two flat strips 30 of electrical conductive material
which are disposed alongside each other in a horl
zontal plane. The outer ends of the strips 30
are secured at 3 I, as by rivets, to insulating raised
portions of the casing 2l. The extreme outer
The space between an inner' liner or shell I6
ends of the strips 30 are bent downward and are
deñning the storage compartment II and the
outer shell I'I of the cabinet I0 is adapted to
curved in vertical planes to form spring clips
adjacent two offset or staggered slots in the bot
tom of the block 2|. The inner ends of two of
contain a suitable heat insulatingA material (not
40 shown).
The outer shell I1 extends about a
wooden door frame I8 with the extreme edge
thereof bearing against the forward part of the
inner edge of the frame. The forward part of
the inner shell I6 at the opening of the storage
_) compartment> II is rounded or curved and pro
vided with an edge portion which bears against
the rearof the inner edge of the frame I8. A
trim strip I9 is secured to the inner edge of the
frame I8 in any suitable manner, as by screws,
50 and overlies the spaced edges of the outer and
inner shells I6 and I1.
In accordance .with our invention we provide
an improved light fixture and switch assembly
20 disposed above the door opening and at the
55 forward part of the top wall of the inner shell
the strips 25 and 30 are fixed to the screws 24, 40 _
and the inner ends of the two other strips 25
and 30 are secured together at 32, as by a rivet,
which causes the flat side of strip 30 to bear
against the upper edge of strip 25.
The connecting block 2| is secured by two
angle brackets 33 to the top part of the frame
I8 >so that the outer end of one arm of the block
extends into a recess 34 formed in the frame i8
approximately at the center of the door opening.
The recess 34 extends to the inside edge of the 50
frame I8 at which region' the trim strip I9 is
provided with an aperture whereby a switch 35
can be plugged into the connecting block 2l.
‘I'he switch 35 is provided with an operating but?
ton 36 which extends through an opening formed
2
2,122,293
in a iiange 31 which overlies the edge of the trim
strip about the aperture and is secured thereto
the block 2| adjacent the ends of the strips
25 are suiliciently wide and the prongs 38 suffi
in any suitable manner, as by screws. The switch` ' ciently long to permit the insertion of the prongs
35 is provided with two spaced prongs 3B which
are adapted to extend through two of the open
ings or slots in the bottom of the block 2| and
frictionally engage the outer ends of the strips
25. The switch 35 is of a well-known type where
in an electrical circuit is closed or completed when
10 -the door is open and the operating button 36 is'
v biased outward, as by a spring; and wherein the
electrical circuit is open when the door I2 is
.closed and the operating button 36 is pressed
inward against the tension of the spring.
15
Directly beneath the connecting block 2| the
top wall of the inner shell I6 is provided with _an
elongated opening ladapted to receive a reflector
' 39 provided with a flange adapted to overlie the
edge of the shell about the opening. A suitable
20 insulating gasket 40 may be ñxed to the underside
of the flange whereby an air-tight seal is ob~
tained when the reflector is positioned in the
opening formed in the liner. Within the re
flector 39 and at one end thereof is secured, as
by a screw 4|, a light socket 42 having the base
thereof extending through an opening in the» top
of the reflector. The light socket 42 is provided
with two offset or staggered prongs 43 which are
adapted to extend through the offset openings or
slots formed in the bottom of the block 2| and
frictionally engage the spring clips formed at the
outer ends of the strips 3|). The light socket 42 is
provided with a threaded socket 44 to receive an
electric bulb 45 of the straight ñlament type.
The reflector 33 and light socket 42 are located
approximately at the center of the door opening
and at the forward part of the top wall of the
inner shell I6, and are disposed between the
inner and outer shells I6 and I'I, a's shown in Fig.
40 2.
When the door I2 is open the switch 35 com
pletes an electrical circuit including the strip 30
secured to one of the screws 24, light socket 42,
the strips 30 and 25 having their inner ends se
cured together, switch 35 and the strip 25 se
45 cured tothe other of the screws 24. When the
door I2 is closed the operating button 36 is
pressed inwardly to open the electrical circuit and
disconnect the bulb 45 from the source of elec~
trical energy.
50
In view of the foregoing, it will be understood
that a simple light fixture and switch assembly
has been provided for cabinet structures. In the
38 into the slots even when the aperture is formed
in the trim strip I9 so that the prongs are not
in direct alignment with the slots. With the light
socket 42 positioned at the forward part of the top
wall of the inner shell I6, it is relatively easy to
insert or change a bulb in the reñector 39.
The
position of the light ñxture and switch assembly '10
at the top part of the door opening is particularly
advantageous because it permits all cabinet struc
tures to be fabricated in the same manner irre
spective of whether right or left«hand doors are
provided on the cabinets.
15

particular embodiment of our invention, it will
be apparent that Various modifications and
changes may be made without departing from
