    摘要： The vibration free handle comprises a mounting member (83) connected to a vibration source (84) via an extension (87), a first rod (81) supported by the mounting member (83), a second rod (82) connected to the first rod (81) at one end thereof with a predetermined inclination (α), a mass body (86) mounted on the other end of the second rod (82), and an elastic member (85) provided between the vibration source (84) and partially fitted in the mounting meber (83) for covering the first and second rods (81, 82). The elastic member (85) possesses spring constants in three directions (x, y, z), one direction (z) being defined by the direction the vibration source vibrates (z-direction) and other two directions being perpendicular to z-direction in a mutual plane perpendicular to z-direction. When the second rod (82), which serves as a grip of the handle, extends perpendicularly to z-direction and the source starts vibrating, there appear "vibration knots" in the second rod (82), at which the vibration ampltude is substantially zero, in three directions (x, y, z). The "vibration knots" reduces the vibration from the vibration source. The amount of vibration reduction in three directions are respectively adjustable by changing the inclination (α).

    摘要： The present invention concerns a handheld working tool comprising a motor part (10), a handle part (20) comprising a handle grip (21), and at least one first type antivibration element (30) arranged between said motor part (10) and said handle part (20), and which element (30) is adapted to isolate 5 the handle part (20) from vibrations in the motor part (10). The working tool (1) is characterized in that it further comprises at least one second type antivibration element (40) arranged adjacent to the first type antivibration element (30). The at least one second type antivibration element (40) is adapted to, when in an active state, prevent vibrations in the motor part (10) 10 from being transferred to the handle grip (21). The second antivibration element (40) is in the active state when the handle grip (21) is loaded during operation of the working tool (1). The working tool is further characterized in that a longitudinal axis (L1) of the second type antivibration element (40) is separated from a longitudinal axis (L2) of the first type antivibration element 15 (30).

    摘要： A hand carried power tool (100) is presented which includes a vibration-producing power unit (15) interconnected with an elongate handle (20). The handle (20) has a base end (24) coupled to the power unit (15) and an opposite free end (28) configured for manual gripping. Additionally a vibration damping member (50), which permits vibration-induced movement between the base end (24) of the handle (20) and the power unit (15), interstitially located between the base end (24) of the handle (20) and the power unit (15). Furthermore, a resilient biasing member (40) is coupled between the elongate handle (20) and the power unit (15). The biasing member (40) connects to the handle (20) at a location distant from the base end (24) of the handle (20) and the biasing member (40) is configured to dampen vibration-induced relative movement between the base end (24) of the handle (20) and the power unit (15).

    摘要： A combustion engine powered, portable, hand-held working machine (1) including a machine body (2), a combustion engine in the machine body, and a number of functional members, at least one of which, a bracket (17), forms part of the machine body or is connected to the machine body, and the machine body is suspended in a handle system (6, 7) via a number of anti-vibration elements (12, 18, 19).
    The anti-vibration element (18; 19) comprises a spring plate (22; 46) having a first end section (22A; 46A), a second end section (22C; 46C), and a flat intermediate, flexible section (22B; 46B, 46B") between said end sections.
    The first end section (22A; 46A) of the spring plate is connected to one of said machine body with connected bracket (17) and said handle system (6, 7).
    A resilient rubber body (23, 23A, 23B; 45) is secured to the second end section of the spring plate, projecting in a transversal direction from the spring plate.
    The resilient rubber body forms a link between the spring plate and the other of said machine body with connected bracket (17) and said handle system (6, 7),
    and a second end section of the spring plate, carrying the resilient rubber body, can oscillate in directions transversal to the plane of the second end section due to vibrations generated in a machine, such that transfer of said vibrations in a transversal direction between said first and second members can be dampened.
