Claims
- 1. A clamping device for clamping together sheets of paper, comprising:
- (A) a clamping body formed of elastic wire and consisting of:
- (1) a pair of arms formed by sections of said wire, and a bight section connecting said arms at proximal ends thereof to form substantially a V-shape in a first plane; said arms being biased apart to diverge from said bight section to define an angle of opening in said first plane; said arms being movable in opposite directions in said first plane towards and away from each other;
- (2) a pair of press members formed by sections of said wire and respectively integrally formed on distal ends of said arms; said press members being disposed on either side of a second plane which is perpendicular to said first plane and bisects said angle of opening, wherein each said press member forms an acute angle with the first plane and said arm to which said press member is attached, said press members having free ends which are disposed closer to the said second plane than the distal ends of said press members, said free ends making an acute angle with said second plane greater than half said angle of opening; and
- (B) a single clamping plate slidably mounted on said arms and having engaging sections forming at least two channels for receiving said arms; said two channels being spaced apart a distance which is less than the spacing between said distal ends of said arms whereby said arms are forced together as said clamping plate is moved from said bight section towards said distal ends so that said press members engage and clamp together sheets of paper placed between said press members.
- 2. A clamping device as claimed in claim 1, wherein said clamping plate has another channel between said two channels, one of said two channels being connected to but slidable with respect to one of said arms, the other two channels being adapted to selectively receive the other one of said arms for varying the spacing between said arms.
- 3. A clamping device according to claim 1, wherein said wire is a single integral wire.
