A handheld work apparatus has a motor unit including a drive motor for driving a tool and a handle unit including a handle. The motor unit and the handle unit are interconnected via at least one antivibration element. A first antivibration element includes a coil spring. A first holding element is attached in a first end of the coil spring. A second holding element is attached in a second end of the coil spring. The first holding element is firmly connected to the motor unit. The second holding element is firmly connected to the handle unit. The holding elements have end faces located in an interior of the coil spring. The end faces have centering elements that can come into contact with each other and thereby center the holding elements with respect to each other. The end faces form a stop for the movement of the handle.

Disclosed is a chainsaw capable of making it less likely that vibrations due to driving of an electric motor and a endless movement of a saw chain are transmitted to a worker, thereby enabling the worker to become less likely to be fatigued even in work using the chainsaw. The chainsaw includes an electric motor provided inside a body casing; a guide bar provided in a front portion of the body casing in such a manner as to protrude forwardly; a saw chain provided around an outer periphery of the guide bar in an endlessly movable manner, and configured to be endlessly moved along the outer periphery of the guide bar under driving of the electric motor; a handle section provided with respect to the body casing, and configured to be gripped by a worker; and an anti-vibration member interposed between the body casing and the handle section.

Disclosed is a chainsaw capable of introducing outside air into a body casing by rotation of a cooling fan to adequately cool a control unit provided inside the body casing. The chainsaw is configured to cool a control unit provided inside a body casing by a cooling fan being rotated under driving of an electric motor, wherein a handle comprises a base portion through which the handle (30) is attached to the body casing, and a grip formed to extend from the base portion in such a manner as to be grippable by a worker; and an air inlet is formed in a counter wall of the body casing opposed to the base portion of the handle, and wherein the base portion is attached to the counter wall of the body casing to cover the air inlet in an air introduceable state.

A work implement is provided with a tool that has an opening. A housing part is provided and a stud bolt is screwed into the housing part. The stud bolt fastens the tool to the housing part. The stud bolt projects axially away from the housing part and projects at least partially into the opening of the tool. A transmission element is provided for transmitting transverse forces, acting transversely to the axial direction, from the tool to the stud bolt. The transmission element is a first element made at least partially of a first material with modulus of elasticity of 1 GPa to 80 GPa, or the transmission element is a second element with a spring element at least partially made of a second material with modulus of elasticity of larger than 80 GPa and with a free space for a spring travel of the spring element.

A sprocket arrangement (5) for a handheld power tool such as a saw, comprising a drive unit configured to rotate a drive shaft and cutting tool configured to be driven by the drive shaft (21) via the sprocket arrangement. The sprocket arrangement (5) comprises a gear (1) and at least one flexible element (6a, 6b) arranged such that the drive shaft (21) in the handheld power tool is resiliently connected to the cutting tool in the handheld power tool. A handheld power tool comprising a drive unit, a drive shaft, driving means, and a sprocket arrangement is also provided.

The invention relates to an electrical work apparatus including an apparatus housing having an electric motor for driving a work tool, a control unit for putting the electric motor into operation, a handle housing having at least one handle for guiding the work apparatus, and a receiving cavity, realized in the handle housing, having an insertion opening for a battery pack for operating the electric motor. For the purpose of decoupling the battery pack in respect of vibration, the handle housing, together with the receiving cavity for the battery pack, is decoupled from the apparatus housing via one and the same antivibration element. A vibration gap is realized between the apparatus housing and the handle housing, wherein the antivibration element at least partly bridges the vibration gap.

A handheld work apparatus includes a first assembly, a second assembly and an anti-vibration unit which includes a coil spring. A first end of the coil spring forms a fastening eyelet fixed to the first assembly by an attachment screw which extends through the fastening eyelet and the head thereof projects into the coil spring. A second end of the coil spring is screwed onto a connecting piece of the second assembly which has an opening extending through the connecting piece and through which an engagement contour in the head of the attachment screw is accessible for a tool. When the work apparatus is in a non-loaded state, the distance (f) between the fastening eyelet and a front end of the connecting piece is the length (g) of the attachment screw. The distance (p) of the above support surface from the front end of the connecting piece is the length (g).

A work apparatus has a first and a second assembly. The second assembly is mounted movably in relation to the first assembly via at least one antivibration element. Formed between the first assembly and the second assembly is a vibration gap, which is bridged by the antivibration element. The work apparatus has a switch, for actuation by an operator, which includes a first contact element and a second contact element. When the switch is closed, the first contact element and the second contact element contact each other. When the switch is open, the first and second contact element do not establish an electrically conductive contact. The second contact element is part of the second assembly. The first contact element is part of the first assembly and, when the switch is closed, the first contact element and the second contact element bridge the vibration gap between the first and second assembly.
