Total Claims: 9
Claim 1
Independent Claim
305 words
A partitioning wall, including: a first panel; a second panel; connecting means for releasably and adjustably joining the first panel to the second panel along an upright edge of each of the first and second panels; first and second upright members, each having a left side portion, a right side portion and a rear face portion, the left side portion and the rear face portion together defining a left corner and the right side portion and the rear face portion together defining a right corner with said left and right side portions being arranged on the same side of the rear face portion extending generally perpendicularly from said rear face portion, said first upright member being provided along one end of the first panel and said second upright member being provided along one end of the second panel; a first right projection provided at the right corner and extending along the first upright member, said first right projection together with said right corner defining a right arcuate groove having generally parallel sides, said right arcuate groove being provided between the first right projection and the rear face portion; a first left projection provided at the left corner and extending along the first upright member, said first left projection together with said left corner defining a left arcuate groove having generally parallel sides, said left arcuate groove being provided between the first left projection and the rear face portion; said connecting means including a joining member having first and second arcuate arms so as to be slidably received within said arcuate grooves of the first and second upright members, said first and second arcuate arms being defined by generally parallel side walls; and, resilient flaps resiliently biased in said first and second upright members along an outwardly facing side of said left and right side portions.

Claim 3
Dependent Claim
64 words
A partitioning wall as defined in claim 1, wherein a first end of said resilient flaps is secured in grooves provided in said first and second upright members and a second end of said resilient flaps overlaps a flange portion of said first and second upright members so as to define a substantially enclosed side channel section in said first and second upright members.
Claim 4
Dependent Claim
63 words
A partitioning wall as defined in claim 2, wherein the arcuate members define an outer radius portion of said first right projection and said first left projection, the rear face portion and the outer radius portion being substantially parallel to one another and of substantially equal length so as to define a vertical plane along an outermost extent of said substantially equal length.
Claim 5
Dependent Claim
34 words
A partitioning wall as defined in claim 1, wherein said first and second arcuate arms and said arcuate grooves interfit and define hinge means for permitting relative rotation of the first and second panels.
Claim 6
Dependent Claim
30 words
A partitioning wall as defined in claim 1, wherein each of the panels is provided with a base section comprising a plurality of separate channels extending along the panels length.
