Abstract
Clamp for clamping one or more sheet shaped products in particular for bundling a small stack of papers. The clamp has a clamp opening (3,9) that by means of an operating member (11, 12, 13) can be brought into a clamping position (FIG. 2), the operating member passing a dead center. An elastic strip (10) bent into a U-shape, with built-up edges, can be inserted into the clamp opening, keeping the clamp opening (3,9) open when in the releasing position and serving as a gripping surface of a small stack of papers, in the position preventing the removal of the operating member (11, 12,13).
Claims9
A clamp for leaf or sheet shaped products, comprising:
- a base plate;
- a clamping plate having an edge;
- a pivoting means for pivotally connecting said base plate and said clamping plate for movement of said edge toward and away from said base plate;
- an operating member which engages said clamping plate and which is movable between a first position in which said edge of said clamping plate is remote from said base plate and a second position in which said edge of said clamping plate is pressed against said base plate, the movement of said operating member from said first position to said second position passing a dead center whereby the second position is stable;
- and
- a spring means for urging said clamping plate away from said base plate, said spring means being a strip bent into a U-shape so as to have first and second leg portions and being made from an elastic material, said first and second leg portions having (a) first and second outsides which lie against said base plate and said clamping plate respectively and (b) first and second insides which serve as gripping surfaces for the products to be clamped when said operating member is in the second position.
