Abstract
A hand-held power tool includes a spring-mounted decoupling device (16) for supporting a tool handle (14) on the tool housing (4) and having a first spring-mounted support (18) and a second spring-mounted support (20) that is spaced from the operational axis (A) in a second direction (y) perpendicular to the first direction (z) further away than the first spring-mounted support (18) that has a smaller spring stiffness along the second direction (y) than along the first direction (z).
Claims13
A hand-held power tool, comprising:
- a housing (4);
- operational means (10) provided in the housing (4) and reciprocating, during an operation, along an operational axis (A) extending parallel to a first direction (z);
- a handle (14);
- and
- a spring-mounted decoupling device (16) for supporting the handle (14) on the housing (4) and having:
- a first spring-mounted support (18) with a first spring;
- and
- a second spring-mounted support (20) with a second spring that is spaced from the operational axis (A) in a second direction (y) perpendicular to the first direction (z) further away than the first support arrangement (18),
- wherein the second spring is shorter in length than the first spring;
- wherein the second spring has a greater spring stiffness than the first spring;
- and
- wherein the first spring of the first spring-mounted support (18) has a smaller spring stiffness along the second direction (y) than along the first direction (z).

- wherein the first spring-mounted support (18) has a first housing-side support arrangement (22) fixedly connected with the housing (4), a first handle-side support arrangement (28) fixedly connected with the handle (14), and a first spring arrangement (32) located between the first housing-side support arrangement (22) and the first handle-side support arrangement (28) for biasing the first housing-side support arrangement (22) and the first handle-side support arrangement (28) away from each other in the first direction (z), and wherein an intermediate space (47) is provided between the first housing side support arrangement (22) and the first handle-side support arrangement (28) in the second direction (y);
- wherein one of the first housing-side support arrangement (22) and the first handle-side support arrangement (28) has a first bar-shaped support member (24) extending parallel to a third direction (x) perpendicular to the first direction (z) and the second direction (y), and another of the first housing-side support arrangement (22) and the first handle-side support arrangement (28) has a first tubular support member (26) radially surrounding the first bar-shaped support member (24), and wherein the one of the first housing-side support arrangement (22) and the first handle-side support arrangement (28) is supported in the first direction (z) with a first side (30) of the first bar-shaped support member (24) lying permanently against the first tubular support member (26) and with a second opposite side (34) of the first bar-shaped support member (24) being placeable against the first tubular support member (26) and being displaceable therefrom, with interposition of the first spring arrangement (32) between the first bar-shaped support member (24) and the first tubular support member (26).
