    摘要: A mount with a first attachment member; a second attachment member spaced from the first attachment member; and resilient members joining the first and second attachment members, each of the resilient members having at least one void, the voids being collapsible under loading between a first open void condition where the mount has a first substantially constant stiffness, and a second collapsed condition where the voids are substantially closed, the mount having a second substantially constant stiffness when the voids are in the second collapsed condition.

    摘要: The present invention relates to a power tool having a housing, a handle having an inlet passage and an outlet passage extending therethrough, and a pneumatic pressure seal/vibration isolator positioned between the handle. The present invention provides a tool that has an excellent handle to housing seal and does not exhibit heavy vibrations. The present invention is also the vibration isolator that seals the handle to the motor housing and reduces vibrational transmissions to a user. Also disclosed is a power tool having a vibration isolator coupled to the housing and handle, and a mechanism for allowing sliding rotation of the handle relative to the vibration isolator, thereby allowing the handle to point in a different direction other than toward the point of impact. The present invention also discloses a pneumatic power tool including a handle, a housing having a first longitudinal axis, and a vibration isolator rotatably coupling the handle to the housing, the vibration isolator including a central opening through which air passes that is not aligned with the first longitudinal axis.

    摘要: A mount for isolating a vibrating member from its support. An elastomeric element is made up of four components that are preferably bonded to the inclined outer surface of an inner member and the inclined inner surface of an outer member. One of the inner and outer members is bifurcated and drawing the two halves into mating engagement results in the elastomeric components being preloaded simultaneously in compression and shear. The elastomeric element is preferably formed with portions which snub movement in each of three orthogonal directions. The dimensions of the pair of elastomeric components above or below the vibrating member may be different than the other pair since the greater compression strain on one pair of components will make its stiffness characteristics more critical to determining the effective stiffness of the mount.
