Abstract
The clamp-unit is arranged in class-1 double-lever configuration. The levers carry a pair of jaws at one end, and magnets at the other end. The magnets are arranged in repulsive pairs, whereby the magnets urge the jaws together.
Claims20
A tabletop operable clamping device, comprising:
- an upper lever-A carrieshaving a jaw-A at a first end of upper lever-A, a magnet-A at a second end of upper lever-A, and a pivot point between the first and second ends of upper lever-A;
- a lower lever-B having a jaw-B at a first end of lower lever-B, a magnet-B at a second end of lower lever-B, and a pivot point between the first and second ends of lower lever-B;
- and
- a lever-pivot at the respective pivot points of upper lever-A and lower-lever B about which jaw-A and jaw-B can undergo relative pivoting movement;
- wherein magnet-A and magnet-B are so mounted on the respective upper and lower levers that like-poles of the magnets lie facing each other to exert a repulsive magnetic force and enable pivoting movement of the respective jaw-ends of upper lever-A and lower lever-B, this pivoting movement being effectible while the device lies on a tabletop surface.

A tabletop operable clamping device, comprising:
- an upper lever and a lower lever arranged in a double-lever configuration to pivot at a lever-point, wherein:
- respective first ends of the upper lever and lower lever have jaws configured to receive a component therein;
- respective second ends of the upper lever and lower lever have at least one pair of magnets arranged with their respective same-poles facing each other, in opposition, such that the at least one pair of magnets repel each other;
- and
- pivoting movement of the upper lever and lower lever at the lever-point is effectible by relative movement between the at least one pair of magnets while the device lies on a tabletop surface.
