Abstract
The absorber for a hand machine tool according to the invention with a linear drive has a case and a body of mass moveable alongside of an absorber axis relative to the case. Force is applied toward a first direction to a first coupling element moveable alongside of the absorber axis, which is coupled with the body of mass using a first spring. Force is applied toward a second direction to a second coupling element moveable alongside of the absorber axis using a second spring coupled with the case. With a movement toward the first direction, the first coupling element is frictionally coupled with the second coupling element and with a movement toward the second direction, it is uncoupled from the second coupling element.
Claims8
An absorber for a hand machine tool with a linear drive, wherein the absorber comprises:
- a case;
- a body of mass moveable alongside of an axis of the absorber relative to the case;
- a first coupling element moveable alongside of the axis of the absorber, with force applied to said coupling element, which is coupled with the body of mass using a first spring toward a first direction;
- a second coupling element moveable alongside of the axis of the absorber, with force applied to said second coupling element using a second spring coupled with the case toward a second direction, which is opposed to the first direction, wherein the first coupling element is coupled in a form-fitting way with the second coupling element in connection with a movement toward the first direction and the first coupling element is uncoupled from the second coupling element in connection with a movement toward the second direction;
- and
- a switching device, which prevents or enables a movement of the first coupling element toward the first direction relative to the case depending on the switching positions and/or prevents or enables a movement of the second coupling element toward the second direction relative to the body of mass depending on the switching positions.
A machine hand tool including:
- an absorber, wherein the absorber comprises:
- a case;
- a body of mass moveable alongside of an axis of the absorber relative to the case;
- a first coupling element moveable alongside of the axis of the absorber, with force applied to said coupling element, which is coupled with the body of mass using a first spring toward a first direction;
- a second coupling element moveable alongside of the axis of the absorber, with force applied to said second coupling element using a second spring coupled with the case toward a second direction, which is opposed to the first direction, wherein the first coupling element is coupled in a form-fitting way with the second coupling element in connection with a movement toward the first direction and the first coupling element is uncoupled from the second coupling element in connection with a movement toward the second direction;
- and
- a switching device, which prevents or enables a movement of the first coupling element toward the first direction relative to the case depending on the switching positions and/or prevents or enables a movement of the second coupling element toward the second direction relative to the body of mass depending on the switching positions.
- wherein the first coupling element has a first stop surface pointing toward the first direction and the second coupling element has a second stop surface pointing toward the second direction
