Abstract:
1. A poster clamp comprising: first and second members, the members comprising first and second gripping surfaces, respectively, for gripping opposing sides of a poster near an edge of the poster, the first and second members being pivotable relative to one another about a first pivot axis for making the two gripping surfaces grip the poster, a third member, pivotally mounted onto the first member about a second pivot axis, and having a camming surface or surfaces spaced from the second pivot axis by a varying radius, the third member thus defining a cam for bearing against an opposing surface of the second member opposite the second gripping surface of the second member, the third member and cam being rotatable relative to the first and second members for selectively biasing the cam against the opposing surface of the second member to pivot the first and second members together so as to move the two gripping surfaces together, an end part of the rotation of the third member into a final clamping position being an over-centre movement for the cam, and each gripping surface for gripping a poster comprises a plurality of grooves, the first and second gripping surfaces intermeshing upon clamping the two gripping surfaces together, whereby, upon compressing the two gripping surfaces onto a poster, the poster will be caused to at least partially deflect into the grooves, wherein the grooves extend generally parallel to one another from one side of the clamp to another side of the clamp, and thus in use being generally parallel to the edge of the poster being gripped by the poster clamp, wherein one or more posts extend up from the first member through one or more holes in the second member for pivotally mounting the third member about the second pivot axis and positioning the second pivot axis overlying the first and second gripping surfaces so that the second gripping surface is located between the first gripping surface and the second pivot axis.
