    Abstract: An anti-vibration device for attaching a compact disk player to an automobile is disclosed whereby the player is positively retained in place and is not subjected to the shocks and vibrations of the vehicle during its normal operation. The device has a generally planar base, a support plate defining a supporting surface for the compact disk player, a clamp to clamp the compact disk player to the support plate and an anti-vibration layer to attach the support plate to the base. The anti-vibration layer has a layer of foam material, which may be a polyurethane foam, and one or more compression coil springs. The use of the foam material serves to dissipate the resonances of the compression spring and provides an effective connection between the support plate and the base. The foam and the coil springs are arranged in such a way that the support plate may move freely with respect to the base.

  • Patent number: 4771989
    Abstract: Two support assemblies for respectively supporting the tapered end and the cylindrical end of an elongated tubular elastomeric spring between two opposed spring seats are disclosed. The support assembly for the tapered end is made up of an elongated retaining member which is positionable generally transverse to and entirely inside the tapered end. This retaining member includes two inclined portions which bear down upon the inside of the tapered end when pulled in an outward direction by a bolt threadably secured to a conventional spring seat. The support assembly for the cylindrical end is made up of a second retaining member which is positionable generally transverse to and entirely inside the cylindrical end. The second retaining member includes a plurality of expandable flange portions which engage the inside of the cylindrical portion as the retaining member is pulled in an outward direction by a bolt threadably secured to the second spring seat.

  • Patent number: 4766708
    Abstract: A shock and vibration resistant structure includes a frame having a plurality of substantially rectangular regions therein. A plurality of modular units are received in the regions. The units have a lower external surface, side external surfaces, and a top external surface. A plurality of shock and vibration isolators extending from portions of the frame toward at least two adjacent external surfaces of the units, isolate the units from shock and vibration. The units are removable and replaceable. An elevator is used to lift the units so that they may be transferred horizontally from the elevator to the frame. Stabilizing members disposed between the units and the frame fall away when the structure is subjected to shock and vibration.

  • Patent number: 4738436
    Abstract: A spring system for resiliently supporting a mass with respect to a base comprises a supporting member mounted for movement and which can be coupled to the mass and is bounded by a portion of a spherical surface which bears against a concentric complementary guiding spherical surface fixed with respect to the base to guide the supporting member to rotate in all directions around the center of the sphere. A circular resilient device is provided in engagement with the supporting member and is supported with respect to the base. The supporting member is coupled to the mass at a point inside the circular resilient device whereby the supporting member is tilted by radial shocks while its spherical surface is guided along the guiding spherical surface and by the deformations of the resilient device as a result thereof, a resilient couple and/or a radial resilient force is developed which tends to move the supporting member into its initial position.

  • Patent number: 4632211
    Abstract: The device is for a motor-drive unit 1 suspended elastically on the structure 5 of a vehicle. The device comprises reverse speed and forward speed abutments 11, 12 of low flexibility which are each interposed between two bearing elements of which one is connected to the support 6 of the unit 1 and the other is connected to a support 16 which is part of the structure 5. One, 18, of the bearing elements of at least one, 12, of the abutments is mounted to be movable relative to its support 16 and is maintained spaced from the latter by a predetermined distance J in a direction perpendicular to the axis of rotation of the unit 1, by means of a highly flexible pre-stressed spring 20. By means of this arrangement, when the gearbox is engaged with a front speed ratio and the vehicle remains stationary, the transmission to the structure 5 of the vibrations of the unit 1 through the forward speed abutment 12 is prevented.

  • Patent number: 4601362
    Abstract: A device for damping an oscillatory system is described. The device comprises a first connection member connectable to part of a spring and a second connection member connectable to a surface on which the spring is mounted. One end of a first bearing member is rotatably mounted in the first connection member and the other end is fixed in a mounting block. One end of a second bearing member is rotatably mounted in the block to extend perpendicularly of the first bearing member. The other end of the second bearing member is fixed in part of a planar component which is pivotally connected by a flexible joint to a second planar component. The device is symmetrical about the pivot line so that a third bearing member and a fourth bearing member corresponding to the second and first bearing member, respectively, are provided between the second planar component and the second connection member.

  • Patent number: 4587995
    Abstract: The suspension for the weaving machine employs vibration-damping bearing elements which have vertical spring constants which differ from each other by at least one order of magnitude. In addition, the sum of the horizontal spring constants of the bearing elements are, at most, one tenth of the greatest vertical spring constants of the bearing elements. The bearing element on the warp beam side is made as a layer bearing while the soft bearing element on the cloth beam side is in the form of an air spring which can be adjusted.The suspension achieves a defined static position of the weaving machine as well as a deep tuning of the suspension system of the machine/bearing elements.
