ABSTRACT:
The invention provides a device for securing a flexible sheet comprising (a) a first substantially U-shaped channel member having a web portion and a pair of opposed legs each of said legs being provided with a lip, which lips are directed substantially towards each other; (b) a second engaging member including a base and at least one depending arm, which member is adapted to engage one of the legs of said channel member with the back of the base of said engaging member facing the other leg of said channel member and the arm of said member disposed between said lip and said web; and (c) a third bar-like clamping member having a width substantially corresponding to the distance between the back of the base of said engaging member, when engaging one leg of said channel member, and the opposite leg of said channel member and a height along at least one of its sides substantially corresponding to the height of said channel member as measured between said lip and said web; the arrangement being such that upon the engagement of said engaging member with the leg of said channel member, with a flexible sheet passed therebetween and extending across said web and over said other leg, the insertion of said bar-like clamping member is adapted to cause the arm of said engaging member to tightly clamp said sheet against said leg and the web adjacent thereto, while one side of said clamping bar is adapted to simultaneously clamp said sheet against at least the other leg of said channel member while the opposite side of said clamping member is firmly pressed against the back of said engaging member's base.
