Abstract

Abstract A modular panel assembly includes more than one first modular unit having a plate member with a rear face, which has first and second connecting corner pieces longitudinally and oppositely disposed near the side faces. The first connecting corner piece of each of the first modular units is engageable with the second connecting corner piece of another first modular unit. The first modular unit further has a plurality of substantially T-shaped protrusions projecting from a front face of the plate member and forming a plurality of substantially T-shaped grooves between them. Each of the T-shaped protrusions has a pair of oppositely extending flange ends. Each of the T-shaped grooves has a restricted opening between two flange ends. The T-shaped protrusions of each first modular unit can engage with the T-shaped grooves of another first modular unit.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 276 words
A modular panel assembly, comprising more than one first modular unit, each first modular unit having a plate member with a front face, a rear face, two oppositely disposed side faces connecting said front face to said rear face, and a bottom edge and a top edge; said rear face having a first connecting corner piece and a second connecting corner piece longitudinally and oppositely disposed near said side faces, said first connecting corner piece having a longitudinal groove, said second connecting corner piece having a longitudinal tongue, said first connecting corner piece of each of said first modular units being engageable with said second connecting corner piece of another said first modular unit; said first modular unit further having a plurality of substantially T-shaped protrusions projecting from said front face of said plate member and forming a plurality of substantially T-shaped grooves between them, each of said T-shaped protrusions having a pair of oppositely extending flange ends, each of said T-shaped grooves having a restricted opening between two said flange ends and being open at said to pand said bottom edges of said first modular units, said T-shaped protrusions of each of said first modular units being engageable with said T-shaped grooves of another said first modular unit; wherein each of said first modulat units has two longitudinal side grooves oppositely formed at said side faces and two pairs of flanks, each pair of said flanks defining one of said side grooves, one of said flanks in each pair being longer than the other said flank, one of said flanks in each pair being adjacent to said rear face and having an inclined edge face.
Claim 2
Dependent Claim 276 words
A modular panel assembly, comprising more than one first modular unit, each first modular unit having a plate member with a front face, a rear face, two oppositely disposed side faces connecting said front face to said rear face, and a bottom edge and a top edge; said rear face having a first connecting corner piece and a second connecting corner piece longitudinally and oppositely disposed near said side faces, said first connecting corner piece having a longitudinal groove, said second connecting corner piece having a longitudinal tongue, said first connecting corner piece of each of said first modular units being engageable with said second connecting corner piece of another said first modular unit; said first modular unit further having a plurality of substantially T-shaped protrusions projecting from said front face of said plate member and forming a plurality of substantially T-shaped grooves between them, each of said T-shaped protrusions having a pair of oppositely extending flange ends, each of said T-shaped grooves having a restricted opening between two said flange ends and being open at said to pand said bottom edges of said first modular units, said T-shaped protrusions of each of said first modular units being engageable with said T-shaped grooves of another said first modular unit; wherein each of said first modulat units has two longitudinal side grooves oppositely formed at said side faces and two pairs of flanks, each pair of said flanks defining one of said side grooves, one of said flanks in each pair being longer than the other said flank, one of said flanks in each pair being adjacent to said rear face and having an inclined edge face.
Claim 3
Dependent Claim 108 words
A modular panel assembly as claimed in claim 1, wherien each of said first and said second connecting corner pieces has an extreme lower end projecting downward from said bottom edge; wherein said first modular units are assembled to form a hollow housing of polygonal cross-section, said modular panel assembly further comprising a second modular unit having a closed bottom and a rectangular looped frame at a bottom of said hollow housing, said second modular unit further having corner sockets adjacent said looped frame to receive said extreme lower ends of said first and said second connecting corner pieces of said first modular units of said hollow housing.
Claim 4
Dependent Claim 51 words
A modular panel assembly as claimed in claim 2, further comprising a third modular unit to be received at a top end of said hollow housing, said third modular unit having a second looped frame with a plurality of intersecting partitioning members formed therein to form a plurality of access openings.
