An up-down cabinet for lowering a cabinet from a wall so that easy access is provided to the cabinet. The cabinet is normally disposed adjacent the wall. By urging the cabinet away from the wall the cabinet pivots outwardly and downwardly on pivotally attached swing arms. The swing arms are attached to cables resting on cable pulleys. The cables are held in tension by coil springs. By applying tension on the cables the cabinet is easily retracted upwardly and rearwardly to its normal position against the wall.

BACKGROUND OF THE INVENTION 
This invention relates generally to cabinets, cabinet housings, and cabinet 
shelves and more particularly but not by way of limitation to an apparatus 
used in lowering and retracting a cabinet housing. 
Heretofore there have been a number of different types of cabinets having 
swingable shelves. The shelves are mounted on arms that pivot and allow 
the shelf to be moved outwardly and downwardly from the cabinet housing. 
Also there are various types of bens, containers, receptacles, etc. that 
are pivotally mounted on arms having springs attached thereto for biasing 
the arms to a retracted position. 
None of the prior art cabinets disclose the novel combination of the 
up-down cabinet as described herein. 
SUMMARY OF THE INVENTION 
The up-down cabinet provides a cabinet housing that can be quickly urged 
outwardly and downwardly for easy access to the cabinet housings. 
The subject invention is biased in its normal position against the wall by 
coil springs. When the cabinet is lowered the tension on the springs is 
increased thereby aiding the user of the cabinet in returning the cabinet 
to its retracted position. 
The up-down cabinet allows the entire cabinet housing to be lowered rather 
than individual cabinet shelves. 
Through the use of cables and cable pulleys coacting with the coil springs 
and swing arms a greater mechanical advantage is provided in lowering and 
retracting the up-down cabinet. 
The up-down cabinet includes a cabinet housing disposed adjacent a wall. 
Assembly plates are attached to the wall and are disposed on each side of 
the cabinet housing. A pair of vertically mounted swing arms are attached 
to each assembly plate and each side of the cabinet housing for pivoting 
the housing outwardly and downwardly. Attached to the swing arms are 
cables mounted on cable pulleys. The cables are attached to coil springs 
mounted to the assembly plates.

DETAILED DESCRIPTION OF THE DRAWINGS 
In FIG. 1 the up-down cabinet is designated by general reference numeral 
10. The cabinet 10 includes a cabinet housing 12 shown in dashed lines and 
in a retracted position against a wall 14. The cabinet housing 12 is 
pivotally attached to assembly plates 16 by an upper swing arm 18 and a 
lower swing arm 20. While it cannot be seen in FIG. 1 the up-down cabinet 
10 includes an identical assembly plate 16 mounted on the opposite side of 
the cabinet housing 12 and including the following described apparatus. 
The upper swing arm 18 and lower swing arm 20 include an upper end portion 
22 and a lower end portion 24. The lower end portion 24 is pivotally 
connected to the cabinet housing 12 by a pivot pin 26. The upper end 
portion 22 is pivotally connected to the assembly plates 16 by a pivot pin 
28. Attached to the lower swing arm 20 and between the pivot pins 26 and 
28 is a cable pivot pin 30 attached to a cable pivot 31. The cable pivot 
31 is attached to one end of a cable 32. The cable 32 rides on a cable 
pulley 34 mounted between the pivot pins 26 and 28 on the upper swing arm 
18. From the cable pulley 34 the cable 32 is looped over a similar cable 
pulley 36 mounted to the top of the assembly plate 16. From the cable 
pulley 36 the cable 32 is looped downward and connected to a spring eye 
38. The cable 32 is held in tension by a vertically disposed coil spring 
39. The coil spring 39 is connected at one end to the spring eye 38 and 
the other end to a spring mounting plate 40. The spring mounting plate 40 
is attached to the bottom of the assembly plate 16. When the cabinet 
housing 12 is in a retracted position the upper swing arm 18 and the lower 
swing arm 20 rest against stops 42. 
In FIG. 2 the cabinet housing 12 is shown in its lowered position. This 
position is obtained by urging the housing 12 outwardly and downwardly. 
During this operation the housing 12 pivots on the upper swing arm 18 and 
lower swing arm 20. The housing 12 is lowered until the lower swing arm 20 
comes to rest against a lower flange portion 44 of the assembly plates 16. 
As the cabinet housing 12 is lowered the cable 32 connected to the lower 
swing arm 20 moves downward rotating on the cable pulleys 34 and 36 and 
urging the coil spring 39 upward thereby increasing the tension on the 
coil spring 39. Due to the weight of the cabinet housing 12 the tension of 
the coil spring 39 is overcome and the housing 12 remains in its lowered 
position. When it is desired to retract the housing 12 it is urged upward 
and rearward and with the help of the spring tension the cabinet housing 
12 is easily returned to its original position against the wall 14. 
FIG. 3 illustrates a front view of the cabinet housing 12 with the assembly 
plates 16 mounted on both sides of the housing 12. The assembly plates 16 
are L-shaped having a first side portion 46 which is attached to the wall 
14 and a second side position 48 which is used for mounting the swing arms 
18 and 20, the pulley 36, and the spring mounting plate 40. As seen in 
FIG. 3 the second side portion 48 acts as a housing to shield the swing 
arms 18 and 20, the pulleys 34 and 36, cables 32, and spring 39 from view 
when looking at the sides of the housing 12. 
In FIG. 4 a top view of the up-down cabinet 10 is seen with the housing 12 
in a retracted position with a portion of an upper flange 50 of the 
assembly plates 16 cut away to expose the upper swing arm 18. In this view 
the first side portion 46 of the assembly plates 16 can be seen disposed 
against and attached to the wall 14. 
Changes may be made in the construction and arrangement of the parts or 
elements of the embodiment as disclosed herein without departing from the 
spirit or scope of the invention as defined in the following claims.
