Claim:
A hinged frame arrangement, comprising: first and second frame members; a hinge having first and second leaves respectively having outer surfaces mounted to said first and second frame members, said first and second leaves being pivotally connected to one another about a pivot axis to permit relative rotatable mounting of said first and second frame members; at least said first frame member having a side surface having a recess extending longitudinally and defining a recess opening and a recess width increasing with depth of said recess into said first frame member; at least said first leaf having a recess engaging member formed as one continuous piece with said leaf, said recess engaging member extending from said outer surface and captively received in said recess by virtue of said recess engaging member having a width which increases with depth in said recess such that said recess engaging member has a width which is greater than a width of said recess opening, said width of said recess opening being sufficiently wide to permit pivoting of said recess engaging member in said recess thereby permitting an angle defined by said outer surface and said side surface to be varied; and locking means for locking maid first leaf relative to said side surface to adjustably set said angle defined by said outer surface and said side surface to be varied.
