The handheld power tool () has a tool socket () to hold a tool () on a working axis () as well as a striking mechanism () with a striker () that is moved periodically back and forth along the working axis (). The striking mechanism () is secured in a tool housing (). A handle () is attached to the tool housing () by means of a damper (). The damper () has a surface () that is joined to the tool housing () as well as a surface () that is joined to the handle. A block () made of a porous elastomer is arranged so as to be in contact with the tool surface () and with the handle surface (). An air-filled cavity () is provided inside the block () between the tool surface () and the handle surface ().

Handheld power tool

The handheld power tool has a tool socket to hold a chiseling tool on a working axis and a striking mechanism that acts upon the tool in the striking direction. The striking mechanism is arranged in a machine housing. A handle is oriented along a handle axis that is perpendicular to the working axis and that is installed on the machine housing by three suspension assemblies. The second suspension assembly has a lever arm that runs along the handle axis. The first end of the lever arm is attached to a machine housing and to a handle. A guide is attached to the other machine housing and handle. The second end of the lever arm in the guide can be forcibly deflected against a spring along a trajectory that is slanted or perpendicular to the working axis.

A hand-held power tool () has a base housing () in which there is provided an operational unit () movable in a reciprocating manner along a operational axis (A) defining a first spatial axis (z) and spaced from a center of gravity (SP) of the hand-held power tool () in direction of a second spatial axis (y) which is perpendicular to the first spatial axis, (z), and further has a cover housing () which is held on the base housing () by decoupling elements and is fixedly connected to a main handle () and to side-handle connection element (), with the decoupling elements having, in a projection perpendicular to a plane (Eyz) defined by the first spatial axis (z) and the second spatial axis (y), a first support device () which is located adjacent to the center of gravity and which holds the cover housing () on the base housing () so as to be displaceable along and pivotal in direction of the first spatial axis (z).

Hand-held power tool

A hand-held power tool () includes a drive () located in the power tool housing () for driving a working tool (), and a torsional pendulum () at least partially mounted on the housing () for compensating vibrations generated by the drive ().

Hand-held power tool with vibration compensator

A hand-held power tool includes a main handle, a percussion mechanism striking along a percussion axis, a counter mass displaceable along an oscillation axis which is inclined to the percussion axis and biasing elements for preloading the counter mass to a rest position on the oscillation axis. The counter mass is arranged such that the rest position is closer to the main handle than the center of gravity is to the main handle.

Hand-held power tool with vibration-compensating mass

A hand-held power tool having a main housing () in which a tool spindle () is at least partially located, and a handle housing () on which a handle () is formed, includes a connection device () for securing the handle housing () to the main housing () and having a first connection element () with a first engagement member () loosely engageable with a second engagement member () associated with the main housing (), and a second connection element () with a handle-side locking element, a main housing side locking element, and a further locking element for formlockingly connecting the handle-side locking element and the main housing side locking element, whereby absence of loose engagement of the first and second engagement members is ensured upon formation of the formlocking connection of the handle-side and main housing side locking elements.

Hand-held power tool having main and handle housings with a connection device for connecting the housings

A hand-held power tool includes a spring-mounted decoupling device () for supporting a tool handle () on the tool housing () and having a first spring-mounted support () and a second spring-mounted support () 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 () that has a smaller spring stiffness along the second direction (y) than along the first direction (z).

Hand-held power tool with a decoupling device

A hand-held power tool includes a spring-mounted decoupling device () for supporting a tool handle () on a tool housing () and having a first support arrangement () including a connecting device () pivotally supported relative to the housing by a housing-side pivotal support () and relative to the handle () by a handle-side pivotal support (), and a second support arrangement () 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 ().
