DESCRIPTION:
BRIEF SUMMARY
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates to a sign comprising a stand; two pairs of first and second parallel support elements secured to the stand; a fabric with edge sections and between them a sign surface for information, extending in a plane between the support elements, and bars around which the edge portion of the fabric are wrapped and by means of which bars the edge portions of the fabric are detachably joined to the support elements, at least the first support element in each pair of support elements comprising a frame profile connected to the stand, and a clamping profile to support said bar provided with said edge portion of the fabric, said frame profile being provided with at least one counter support arranged at an outer edge portion of the frame profile located near the plane of the fabric in order to form a center of pivot for the clamping profile, the latter being provided with a flange arranged at an outer edge part of the clamping profile located near the plane of the fabric and defining an assembly pocket for receipt of the bar with the edge portion of the fabric wrapped around it via an opening, the clamping profile also being provided with a support member arranged to be brought into engagement with said counter support to permit pivoting of the clamping profile in relation to the frame profile about said center of pivot to a final position behind the plane of the fabric while clamping the fabric in relation to the second one of the two support elements, said second support element comprising a flange and an assembly pocket formed thereby and having the same shapes and functions as the equivalent elements of the first support element.
The European patents EP-0 114 453 and EP-0 268 308 describe signs in which the outer edges of the fabric are wrapped around retaining bars which are thereafter inserted in a recess in each of a plurality of fabric-retaining elements adjustably secured by bolts to the rod-shaped frame profiles. When the bolts extending through a vertical flange on each fabric-retaining element are tightened, the fabric is stretched. The frame-profile rods are provided with a longitudinal slit facing the fabric, the opposing sides of the slit having longitudinal grooves or ridges to provide a grip for the thread of each bolt. Such an arrangement for tensioning the fabric requires holes for the bolts to be drilled or punched in the flanges of the fabric-retaining elements, as well as the use of bolts requiring a certain amount of time for assembly and adding considerably to the material and assembly costs of a tension-fabric sign.
Signs with a different system of frame profile rods are sold under the name of Signcomp Tensioning System by Designtone Limited, England. The design of the frame profile rods here is even more complicated and includes at least one, but in some case two, longitudinal closed channels, which makes them expensive to manufacture. When the fabric is to be tensioned its edge is folded over a bar, short in relation to the length of the fabric, having a shallow U-shaped cross section, and an extremely complicated clip is snapped over it. The ends of the clip are provided with longitudinal teeth and are intended to be inserted laterally into a longitudinal open channel arranged in the frame profile rod. The cross-sectional dimensions of the channel are designed to suit the clip and one side of the channel is provided with teeth or ridges to cooperate with the teeth on the clip. The fabric is tensioned by pressing the clip into the open channel with the aid of a tensioning tool, and the tension in the fabric inclines the clip in the channel so that the fabric is firmly clamped between the clip and the opposing side of the channel.
Signs with a similar sign assembly are known through the patent specifications U.S. Pat. No. 4,937,961 and U.S. Pat. No. 5,033,216. However, the clips are manufactured by punching a blank out of resilient sheet metal and bending the punched blank. Instead of the longitudinal teeth at the ends of the c
