DETAILED DESCRIPTION We claim: 1.
A clamping device securing an axially displaceable rod in optional adjustment positions, the clamping device comprising a housing having an interior, wherein the rod extends through the housing, and a lever having first and second ends, a push button extending outwardly through the housing attached to the first end of the lever, means for biasing the push button out of the interior of the housing, and a rolling body mounted on the second end of the lever, the interior of the housing having an inclined wall portion, wherein the rolling body contacts the inclined wall portion, such that the inclined wall portion acts to clamp the rolling body against the rod for locking the rod.
2.
The clamping device according to claim 1, wherein the lever comprises two parallel arms, the arms being connected to one another through a crosspiece at the second end of the lever and through the push button at the first end of the lever, wherein the push button extends diagonally relative to the crosspiece.
3.
The clamping device according to claims 1 or 2, wherein the housing has opposite housing walls, further comprising axles extending between the opposite housing walls, wherein the second end of the lever is mounted so as to be swivelable on the axles.
4.
The clamping device according to claim 1, wherein the second end of the lever has outwardly open recesses, wherein the rolling body is loosely received in the recesses.
5.
The clamping device according to claim 1, wherein the push button has an inner chamber, wherein the means for biasing the push button is a pressure spring mounted in the inner chamber and contacting the rod.
6.
The clamping device according to claim 1, wherein the housing is open at a side thereof facing away from the push button.
Description:
BACKGROUND OF THE INVENTION 1.
Field of the Invention The invention is directed to a clamping device, in particular for securing an axially displaceable rod in optional adjustment positions, in which the object or rod to be clamped is clamped by a rolling body supported at a housing enclosing it
