  • Patent number: 6595483
    Abstract: A vibration isolator including a bearing support and an elastic member that communicates with a vibration source. The elastic member is capable of bending from an original position to assume a more or less bowed position in response to changes in a load applied to the midportion of the elastic member intermediate its ends and returning essentially to its original position when the original load is restored. The elastic member engages a friction-resistant bearing surface on the bearing support at a distance spaced from each of its ends and moves relative to the bearing surface in response to a bending of the elastic member. The apparatus may be tuned to effectively isolate a particular vibration frequency, for example, by altering the properties of the elastic member or by changing the distance between the points on the bearing support that engage the elastic member.

  • Patent number: 6086615
    Abstract: A pylon includes a first end portion connected to a patient's leg stump and a second end portion connected to a prosthetic foot. The second end portion includes a piston, and the first end portion includes a piston chamber receiving the piston. The second end portion is thus rotatable and axially movable relative to the first end portion about and along a longitudinal axis of the pylon, respectively. The piston chamber encloses a compressible volume of fluid through which substantially all of the patient's weight applied through the patient's leg stump is supported. The compressible volume of fluid is sealed so that it can be pressurized. Also, a torsional spring couples the piston and piston chamber and resists relative rotation between the piston and piston chamber without supporting any substantial portion of the patient's weight applied through the patient's leg stump to the piston. The present invention thus advantageously provides a pylon which is more cushioned and resilient than conventional pylons.

  • Patent number: 6057618
    Abstract: A support assembly for supporting a rotating shaft relative to a structure in which a first magnetized member is attached to the shaft for rotation therewith, a support member is connected to the structure and at least one damper member connects the support member to a second magnetized member for supporting the second magnetized member in a portion relative to the first magnetized member. The respective magnetic fields of the first and second magnetized members are such that radial deflective movement of the shaft, and therefore the first magnetic member, causes corresponding radial movement of the second magnetized member which is dampened by the damping member.

  • Patent number: 5620169
    Abstract: A rotary mount flexural pivot is disclosed which is integrally formed from a single piece of feed stock and which uses no mechanical connections. Two hollow cylindrical mounts are axially aligned and at least two flexural members are disposed on the interior of these two mounts, are integrally interconnected with each of these two mounts, and cross to define an intersection. These two flexural members are integrally interconnected with each other along the entire extent of this intersection. The mounts therefore move relative to each other by a relative rotation about the flexural member intersection.

  • Patent number: 5570867
    Abstract: An improved shock isolating mount is provided that permits selection of either a high or a low separation strength. The shock mount comprises interfitting flanged spacer and thimble members and resilient rings mounted thereto. The thimble is formed from a hollow plastic stem and a metal base. The metal base includes a flange and an internally threaded post. The thimble stem fits over and snaps onto the post. The metal base member is made in either a high strength or low strength configuration. Selection of the appropriate configuration of base member provides a shock mount assembly of the desired separation strength.

  • Patent number: 5439203
    Abstract: The vibration-damping bushing is provided having an outer cylinder and an inner cylinder which are coaxially arranged with each other. A ring-shaped insert which is made of a resin material having good slidability is inserted between the outer cylinder and the inner cylinder so that the inner peripheral surface of the insert is closely disposed to the outer peripheral surface of the inner cylinder. A pair of ring-shaped vibration-damping rubber members are press-fitted between the outer cylinder and the inner cylinder on both sides of the ring-shaped insert with metallic sleeves joined to the inner and outer peripheral surfaces of said ring-shaped vibration-damping rubber members, respectively. The inside axial end of the inner peripheral surface of each vibration-damping rubber member is spaced apart from each axial end surface of the insert by a predetermined distance.

  • Patent number: 5295652
    Abstract: A grommet assembly useful in attaching articles to a carrying structure includes a first and second annular grommet piece, each conformed for mating engagement to the other, the first grommet piece including a central boss extending axially from one side of an annular base provided with a tapered cavity therein. The second grommet piece is similarly provided with an axial boss tapered on the exterior to fit within the cavity. The free edge of the second boss includes a peripheral bead conformed to engage an interior recess in the cavity. The grommet pieces may be joined to each other by a flexible strap and the first piece may include a bedded washer on the surface opposite to the first boss. Both the grommet pieces and the strap may be formed of a resilient material structure and when the bosses are mated in each other the subsequent compression of the assembly will expand the combined sectional dimension thereof for compressing against the surfaces of any suspension device.

  • Patent number: 5030490
    Abstract: A composite structure of elastic and viscoelastic components in which dynamic loads are effectively damped by transmission through the viscoelastic components. The structure includes a continuous sandwich comprised either of a single elastic layer enclosed by two viscoelastic layers or of a single viscoelastic layer enclosed by two elastic layers such that the sandwich has little stiffness in any intended direction of loading, and two segmented elastic layers having stiffness in a desired loading direction. The segmented layers have alternating segments and gaps and are disposed one on each side of the viscoelastic layer in such a manner that the gaps of one segmented layer overlap the segments of the other segmented layer. Dynamic loads in the loading direction are transmitted back and forth from one segmented layer to the other, through the continuous sandwich layer containing the viscoelastic material, which thereby provides a high degree of damping.
