Abstract
Abstract A basic extrusion is in the form of a ''''J'''' on the back of the long upright. There are several extended vanes or flags, preferably three. The extrusions are in suitable lengths for assembling into cabinets using mitered corners. There is also provided a hanger channel, which can be incorporated into a wall and from which the cabinet can hang by the channel portion forming the bottom of the J. Stacking extrusions for stacking together several J''s are also provided. These extrusions fit into two J''s with their bottom channels next to each other. The basic J extrusions are of strong material, preferably aluminum, but the stacking extrusions are usually of plastic having a certain amount of give.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
A multi-purpose modular building element in the form of an extrusion comprising a long vertical leg, at one end of which, there is positioned a bottom channel which forms a stylized bowl to provide a bottom of a J, three flags, spaced equidistant from one another which protrude from the long vertical leg in the opposite direction from the bottom channel and at the opposite end of the long vertical leg from the bottom channel wherein all adjoining parts of the element are at right angles with one another.
Claim 2
Dependent Claim
89 words
A multi-purpose modular building element in the form of an extrusion comprising a long vertical leg, at one end of which, there is positioned a bottom channel which forms a stylized bowl to provide a bottom of a J, three flags, spaced equidistant from one another which protrude from the long vertical leg in the opposite direction from the bottom channel and at the opposite end of the long vertical leg from the bottom channel wherein all adjoining parts of the element are at right angles with one another.
Claim 3
Dependent Claim
34 words
An element according to claim 1 in which the flags are of substantially the same length as that leg of the bottom channel of the J that is parallel to the long vertical leg.
Claim 4
Dependent Claim
39 words
An element according to claim 2 in which the inner surface of that leg of the bottom channel of the J that is parallel to the long vertical leg is provided with serrations extending lengthwise of the element extrusion.
Claim 5
Dependent Claim
39 words
An element according to claim 1 in which the inner surface of that leg of the bottom channel of the J that is parallel to the long vertical leg is provided with serrations extending lengthwise of the element extrusion.
Claim 6
Dependent Claim
71 words
A wall hanger strip for a structure made up of J extrusions according to claim 1, said strip being an extrusion with flanges to fit against a wall when embedded therein and a bottom lip dimensioned to hook into the channel of an inverted J extrusion, whereby a modular construction having a J extrusion along its rear inverted with the channel pointing out can be hung into the wall hanger strip.
Claim 7
Dependent Claim
71 words
A wall hanger strip for a structure made up of J extrusions according to claim 2, said strip being an extrusion with flanges to fit against a wall when embedded therein and a bottom lip dimensioned to hook into the channel of an inserted J extrusion, whereby a modular construction having a J extrusion along its rear inverted with the channel pointing out can be hung into the wall hanger strip.
Claim 8
Dependent Claim
42 words
A modular construction of J extrusions according to claim 1 having at least one extrusion with its bottom channel extending inwardly of the structure on each side and drawers provided with rollers dimensioned to roll in the channels of the J extrusions.
Claim 9
Dependent Claim
42 words
A modular construction of J extrusions according to claim 2 having at least one extrusion with its bottom channel extending inwardly of the structure on each side and drawers provided with rollers dimensioned to roll in the channels of the J extrusions.
Claim 10
Dependent Claim
31 words
A modular structure of J extrusions according to claim 1 in which there are J extrusions opposite each other with their flags pointing inwardly and adapted to support a shelf thereon.
Claim 11
Dependent Claim
42 words
A modular structure of J extrusions according to claim 2 in which there are J extrusions opposite each other with their flags pointing inwardly and adapted to support a shelf thereon, and shelves having end portions fitting into the channels between flags.
Claim 12
Dependent Claim
76 words
A modular structure according to claim 12 in which the shelf end has a groove, the sides of the groove fitting into channels between the middle flag and the upper and lower flags respectively. 12. A modular structure of J extrusions according to claim 1 having pairs of extrusions with their bottom channels extending inwardly and opposite each other and shelves having a bottom groove positioned to fit over the short legs of the extrusion channels.
