Abstract
The clamping device has a clamping element (9) which can be moved from a starting position into a clamping position. The clamping element (9) is located in a housing (6) and bounds a pressure space in which a pressure medium is accommodated. By actuation of a trigger element (52), the pressure medium acts on the clamping element (9), which as a result is moved out of the starting position and into the clamping position. No tool is required to trigger the clamping element (9), and so the clamping device (9) can be handled easily and without problems. The trigger element (52) is a constituent part of the clamping device (9) and is available whenever the clamping operation is intended to be initiated.
Claims17
A clamping device comprising:
- a housing having a pressure chamber;
- a clamping element disposed in the housing and moveable from a starting position into a clamping position;
- wherein the clamping element delimits the pressure chamber in the housing;
- a pressure medium disposed in the pressure chamber;
- a trigger element acting on the pressure medium;
- wherein the pressure medium, when actuated by the trigger element, moves the clamping element in a pressure loading direction from the starting position into the clamping position;
- a clamping ring, wherein the clamping element is provided with a first connector and a first end of the clamping ring is connected to the first connector;
- wherein the housing has a second connector and a second end of the clamping ring is connected to the second connector;
- wherein the first and second ends are annular and elastically expandable.

A clamping device comprising:
- a housing having a pressure chamber;
- a clamping element disposed in the housing and moveable from a starting position into a clamping position;
- wherein the clamping element delimits the pressure chamber in the housing;
- a pressure medium disposed in the pressure chamber;
- a trigger element acting on the pressure medium;
- wherein the pressure medium, when actuated by the trigger element, moves the clamping element in a pressure loading direction from the starting position into the clamping position;
- a clamping ring operatively connected to the clamping element;
