Abstract
A mounting for a sheet that has a bead about its periphery includes frame members forming a rectangle with each frame member including mutually parallel multiple engagement surfaces defined on ribs. An elongate retainer includes an elongate flange with an interlocking surface which can selectively interlock with any one of the engagement surfaces on the frame. The frame also has a frame rail having a rail surface that faces away from a retainer rail surface on a rail of the retainer. A tool including pinch rollers squeeze the rail surfaces toward one another to place the sheet material held by the retainer in tension while the interlocking surface is engaged with the appropriate engagement surface.
Claims10
A mounting for a sheet having a periphery defining at least two opposed edges, comprising
- a first elongate frame member;
- a second elongate frame member displaced from the first elongate frame member engageable with one of the opposed edges of the sheet,
- the first elongate frame member including a continuous frame rail extending continuously substantially the length of the first elongate frame member and facing away from the second elongate frame member;
- and
- an elongate retainer associated with the first elongate frame member, and including an elongate retainer element to engage the sheet along the other of the two opposed edges and a continuous retainer rail facing away from the frame rail and extending continuously substantially the length of the frame rail,
- one of the first elongate frame member and the elongate retainer further including engagement surfaces facing away from the second elongate frame member and the other of the first elongate frame member and the elongate retainer further including an interlocking surface positionable in interlocking engagement with any one of the engagement surfaces, the interlocking surface being movable laterally of the engagement surfaces to be positioned in interlocking engagement with any one of the engagement surfaces, there being an unequal number of the engagement surface and the interlocking surfaces for tension adjustment of the sheet.
