Abstract
Abstract A modular cabinet structure is provided. The structure includes a first level framework and an identical second level framework. Each of the frameworks includes a rear wall having a pair of sidewalls extending transversely from opposite ends of the rear wall. A pin extends inwardly from at least one of the sidewalls and a locking tab is pivotally mounted to the sidewall by the pin. The tab includes a slot adapted to engage the pin of the other framework to enable the frameworks to be secured to one another.

Total Claims: 5
Claim 1
Independent Claim
260 words
A modular cabinet structure comprising: a. a first level framework having a rear wall; a pair of sidewalls extending transversely from opposite ends of said rear wall; each of said sidewalls having a lower end and an upper end, a pin extending inwardly from at least one of said sidewalls adjacent one of said ends, a locking tab pivotally mounted to said one sidewall by said pin, and a slot extending through portions of said tab; b. a second level framework having a rear wall; a pair of sidewalls extending transversely from opposite ends of said rear wall; each of said sidewalls having a lower end and an upper end, a pin extending inwardly from at least one of said sidewalls adjacent one of said ends; said second framework pin having an enlarged head at its inner end and said first framework slot having a first section sufficiently large to receive said pin enlarged head and a second section smaller than said pin head whereby said pin head can pass through said slot first section to be captured by said slot second section to lock said frameworks together; and, c. one of said frameworks being stacked one on top of the other of said frameworks with said first framework lock tab slot engaging said second framework pin whereby to secure said frameworks to one another; said first framework slot defining a camming surface for said second framework pin, whereby rotation of said tab produces a camming action between said slot and pin tending to draw said frameworks toward one another.
Claim 2
Dependent Claim
260 words
A modular cabinet structure comprising: a. a first level framework having a rear wall; a pair of sidewalls extending transversely from opposite ends of said rear wall; each of said sidewalls having a lower end and an upper end, a pin extending inwardly from at least one of said sidewalls adjacent one of said ends, a locking tab pivotally mounted to said one sidewall by said pin, and a slot extending through portions of said tab; b. a second level framework having a rear wall; a pair of sidewalls extending transversely from opposite ends of said rear wall; each of said sidewalls having a lower end and an upper end, a pin extending inwardly from at least one of said sidewalls adjacent one of said ends; said second framework pin having an enlarged head at its inner end and said first framework slot having a first section sufficiently large to receive said pin enlarged head and a second section smaller than said pin head whereby said pin head can pass through said slot first section to be captured by said slot second section to lock said frameworks together; and, c. one of said frameworks being stacked one on top of the other of said frameworks with said first framework lock tab slot engaging said second framework pin whereby to secure said frameworks to one another; said first framework slot defining a camming surface for said second framework pin, whereby rotation of said tab produces a camming action between said slot and pin tending to draw said frameworks toward one another.
Claim 3
Dependent Claim
15 words
The structure in accordance with claim 1 wherein said first and second frameworks are identical.
Claim 4
Dependent Claim
20 words
The structure in accordance with claim 1 further comprising drawer supporting means extending inwardly from each of said framework sidewalls.
Claim 5
Dependent Claim
51 words
The structure in accordance with claim 1 wherein said first level framework pin is adjacent said sidewall lower end and said sidewalls include a lower portion extending downwardly from a line along said pin, said lower portion being stepped inwardly for a distance substantially equal to the thickness of said sidewall.
