Patent ID: 7178281

Claim:
A fabric sign comprising at least one pair of parallel support elements for attachment to a base and a fabric comprising two parallel edge portions for assembly on one each of the support elements, at least one of the support elements comprising: a frame profile that includes, an attachment part for said attachment to the base, and a counter support part that includes an inner wall section forming a continuation of said attachment part, an outer, flange-like wall section with a free supporting end to form a pivot (A), and an end wall section connecting the inner and outer wall sections, said wall sections defining between them a clamping pocket, and a clamping profile for clamping the fabric to the frame profile, which clamping profile comprises a pressure part for manual actuation, retaining devices for retaining the edge portion of the fabric, and an engagement part arranged to cooperate with the inner and outer wall sections of the counter support when the pressure part is pressed against the attachment part while the clamping profile is turned about said pivot (A), at the same time creating tensile stress in the fabric, characterized in that the outer wall section of the counter support has a predetermined minimum extension, seen in a cross section of the frame profile, that allows the clamping profile to exceed an equilibrium defined by a predetermined angle a between the frame and clamping profiles, at which exceeding of the equilibrium the tensile stress acts to move the clamping profile to a locked position in which the clamping profile is in locked engagement with the frame profile, said locked position being maintained by the tensile stress.
