The invention relates to a hand machine tool (2), particularly a percussion drill and/or percussion hammer, comprising a housing (4) having two parallel appendages (20, 22), a hollow, U-shaped, rounded handle (10) with a yoke (24) and two parallel legs (26, 28), said handle being movably supported o
The invention relates to a hand machine tool (2), particularly a percussion drill and/or percussion hammer, comprising a housing (4) having two parallel appendages (20, 22), a hollow, U-shaped, rounded handle (10) with a yoke (24) and two parallel legs (26, 28), said handle being movably supported on springs in relation to the housing (4) for the purpose of damping vibration. The appendages (20, 22) of the housing (4) extend into both hollow legs (26, 28) of the rounded handle (10). The invention also comprises two coupling elements (34, 36) situated in the hollow yoke (24) of the rounded handle (10) which serve to synchronize the movements of both legs (26, 28). The external end faces of the coupling elements (34, 36) are flexibly connected to the appendages (20, 22). The coupling elements (34, 36) are connected on the other end faces thereof to the rounded handle (10), and cross each other, and are flexibly connected to each other at the crossing point.

What is claimed is: 1. A hand-held power tool in the form of a rotary hammer and/or percussion hammer, including:a housing with two rigid parallel projections, a hollow, U-shaped, rounded handle with a yoke and two parallel legs, wherein said rounded handle is resiliently supported such that said handle is movable relative to the housing in order to dampen vibrations, wherein the projections of the housing extend into said parallel legs of the rounded handle; andsynchronizing means for synchronizing motion of the two parallel legs along said projections, wherein said synchronizing means for synchronizing motion of the two parallel legs are two coupling elements accommodated in the yoke of the rounded handle, wherein said coupling elements are provided and configured exclusive to spatially synchronize motions of the legs unidirectionally and to temporally synchronize motions of the legs,wherein the coupling elements cross each other at a crossing point, and are hingedly interconnected at the crossing point,and wherein each of said coupling elements has a first external end face located at one side of said crossing point, spaced from said crossing point in one direction and hingedly connected with one of the projections, and a second end face located at opposite side of said crossing point, spaced from said crossing point in an opposite direction and connected with the rounded handle.
