  • Patent number: 5716037
    Abstract: An isolator for protecting a display object from damage as a result of shock and vibration associated with seismic activity or other external forces. The isolator has a base support which is fixed in position with respect to the ground, an intermediate support which interengages with the base support and may slide side-to-side along one axis, a top support for mounting the object thereon and interengaging with the intermediate support to slide side-to-side along a different axis, and restoring means to urge the top and intermediate supports to return to their neutral rest positions. The interengagement between levels is accomplished by tracks that slidably engage rows of roller bearings rotatably mounted along opposite side edges of an adjacent support, and the restoring means include elongated, non-flexible compression spring assemblies formed by stacked Belleville washers that yieldably urge follower rollers against cam tracks formed along the sides of the supports.

  • Patent number: 5035394
    Abstract: An isolator for seismic activity including an upper level for supporting an object to be protected, an intermediate level, and a lower level for attachment to the floor or other structure. An interconnection is provided between the upper and intermediate levels to permit relative movement between the levels along a first axis, and a similar interconnetion is provided between the intermediate and lower levels to permit relative between along a second axis perpendicular to the first axis. Each of the interconnections includes one or more bars mounted on one of the levels and defining guide faces oblique to the axis of movement, and a lever pivotally mounted on the other of the levels with a roller for engaging the guide faces, with a spring biasing the roller toward the guide faces. The interconnection also includes tracks and bearings riding on the tracks to provide the interface movement between the levels.
