Title: MACHINE TOOL HAVING ADJUSTABLE HANDLE ASSEMBLY
Abstract:
The invention relates to a machine tool (2), comprising a machine tool housing (4) and a handle assembly (6), which can be adjusted in the angular position thereof relative to the machine tool housing (4), the handle assembly (6) containing: at least one handle (10) having at least one coupling element (26), which handle, relative to at least one counter coupling element (30) of the machine tool housing (4), is adjustable in the angular position of said handle and is linearly movable along a movement axis (X), and a locking mechanism (8), which is designed to fix the handle (10) in a coupled state, in which the coupling element (26) of the handle (10) is in engagement with the counter coupling element (30) of the machine tool housing (4), such that the handle (10) and the machine tool housing (4) are fixedly connected to each other, and to release the handle in an uncoupled state, in which the coupling element (26) of the handle (10) is disengaged from the counter coupling element (30) of the machine tool housing (4), such that the handle (10) can be adjusted in the angular position thereof relative to the machine tool housing (4), the locking mechanism (8) containing: an eccentric lever (36) having a first end (44) and a second end (46), which eccentric lever can be reversibly pivoted about a pivot axis (S), which extends perpendicularly to the movement axis (X) and is provided in the region of the second end (46), between a locking position and a release position, at least one bearing element (38) for pivotably supporting and retaining the eccentric lever (36), and a stop (74) for the eccentric lever (36) for defining a predetermined distance between the pivot axis (S) and the counter coupling element (30) of the machine tool housing (4), at least one cam contour (52) being provided at the second end (46) of the eccentric lever (36), the center point (54) of which cam contour lies outside of the pivot axis (S), such that the handle (10) is transferred into the coupled state by pivoting of the eccentric lever (36) into the locking position and is released into the uncoupled state by pivoting of the eccentric lever (36) into the release position.
