Abstract
Abstract A cabinet for high shock and vibration environments such as shipboard use. A pair of side panels are bolted to the deck or other rigid structure. Front, top and back panels are then secured to the side panels through mating surfaces capable of transferring shear forces. The mating surfaces include cooperating tooth forms. The tooth forms have sloping sides that produce a wedging interfitting relationship between the plates and side panels.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
173 words
A cabinet assembly comprising: a pair of side panels, said side panels being generally planar and adapted for vertically upright and parallel mounting, said side panels being adapted to be secured together in spaced apart relationship by being secured through the upper and lower ends thereof, said side panels having a mating surface along at least a portion of the forward facing edges thereof, at least one generally planar front plate, said front plate being adapted for extending between spaced side panels and having spaced mating surfaces adapted to cooperatively engage said mating surfaces on said side panels, said mating surface collectively having a plurality of parallel elongated protrusions and alternate parallel channels, said protrusions having sloping sides converging toward the outer portions of said protrusions, fastener means adapted for being received on said front plate and said side panels for drawing opposing protrusions and channels into a wedging interfitting engagement so that vibrationally induced shear forces are transferred between said front plates and said side panels through the engaged protrusions and channels.
Claim 2
Dependent Claim
173 words
A cabinet assembly comprising: a pair of side panels, said side panels being generally planar and adapted for vertically upright and parallel mounting, said side panels being adapted to be secured together in spaced apart relationship by being secured through the upper and lower ends thereof, said side panels having a mating surface along at least a portion of the forward facing edges thereof, at least one generally planar front plate, said front plate being adapted for extending between spaced side panels and having spaced mating surfaces adapted to cooperatively engage said mating surfaces on said side panels, said mating surface collectively having a plurality of parallel elongated protrusions and alternate parallel channels, said protrusions having sloping sides converging toward the outer portions of said protrusions, fastener means adapted for being received on said front plate and said side panels for drawing opposing protrusions and channels into a wedging interfitting engagement so that vibrationally induced shear forces are transferred between said front plates and said side panels through the engaged protrusions and channels.
Claim 3
Dependent Claim
49 words
The cabinet assembly according to claim 1 wherein; said side panels have mating surfaces along substantially the entire forward facing edges thereof, and a plurality of planar front plates being adapted to be secured between mating surfaces of said side panels at vertically spaced portions of said side panels.
Claim 4
Dependent Claim
25 words
The cabinet assembly according to claim 2 wherein; said mating surfaces on said side panels extend along the upper horizontal edges of said side panels.
Claim 5
Dependent Claim
23 words
The cabinet assembly according to claim 3 wherein; said mating surfaces extend along substantially the entire rearward facing edges of said side panel.
Claim 6
Dependent Claim
38 words
The cabinet assembly according to claim 1 wherein; said plurality of parallel elongated protrusions on a first of said mating surfaces are at right angles to said plurality of parallel elongated protrusions on the second of side panels.
Claim 7
Dependent Claim
21 words
The cabinet assembly according to claim 1 wherein; said sides of said protrusions converge at an included angle of approximately 24°.
Claim 8
Dependent Claim
43 words
The cabinet assembly according to claim 1 wherein; said fastener means comprise a plurality of fastener elements in each of said front plates; said fastener elements being received through said front plates and into said side panels through the cooperating mating surfaces thereof.
Claim 9
Dependent Claim
41 words
The cabinet assembly according to claim 1 wherein; said mating surfaces on said front plate extend at an angle to the general plane of said front plate to produce the minimum thickness of said front plate at the outermost portions thereof.
