Abstract
A vibration isolator includes a housing having a top surface, an opposing bottom surface, and a hollow interior and an open-ended sleeve having a hollow interior and an extending flange, the extending flange having a top surface and a bottom surface. A resilient core, having a hollow interior, is positioned between and fixedly coupled to the bottom surface of the housing and the top surface of the flange of the sleeve. The resilient core is disposed within a portion of the hollow interior of the open-ended sleeve. A first bushing is disposed within the interior of the sleeve. The first bushing has a flange including a bottom surface that overlays a top surface of the resilient core. A second bushing is disposed within the first bushing.
Claims20
A vibration isolator comprising:
- a housing having a top surface, an opposing bottom surface and a hollow interior;
- an open-ended sleeve having a hollow interior and an extending flange, the extending flange having a top surface and a bottom surface;
- a resilient core, having a hollow interior, positioned between and fixedly coupled to the bottom surface of the housing and the top surface of the flange of the sleeve, the resilient core disposed within a portion of the hollow interior of the open-ended sleeve;
- a first bushing disposed within the interior of the sleeve, the first bushing having a flange including a bottom surface that overlays a top surface of the resilient core;
- and
- a second bushing disposed within an axial through opening of the first bushing in which the axial through opening is eccentrically disposed relative to a center longitudinal axis of the isolation assembly.
A vibration isolating monument mount, comprising:
- a housing having a top surface and an opposing bottom surface;
- an open-ended sleeve having a hollow interior and an extending flange, the flange having a top surface and a bottom surface, the bottom surface of the flange flush with a bottom surface of the sleeve;
- a resilient core positioned between and secured to the bottom surface of the housing and the top surface of the flange of the sleeve, the resilient core conforming to a portion of an inner surface of the housing to form an upper surface;
- a first bushing retained within the cylindrical sleeve such that the first bushing overlays a top surface of the resilient core;
- and
- a second bushing retained within an axial through opening of the first bushing in which the axial through opening is eccentrically disposed relative to a center longitudinal axis of the monument mount.
A method of manufacturing a vibration isolator, the method comprising:
- providing a housing having a top surface and an opposing bottom surface;
- providing an open-ended sleeve having a hollow interior and an extending flange, the flange having a top surface and a bottom surface, at least a portion of the sleeve being disposed within the housing;
- providing a resilient core configured to be bonded to the bottom surface of the housing and the top surface of the flange of the sleeve;
- providing a first bushing configured to be disposed within the sleeve such that the first bushing overlays a top surface of the resilient core;
- and
- providing a second bushing configured to be disposed within an axial through opening of the first bushing in which the axial through opening is eccentrically disposed relative to a center longitudinal axis of the isolator.
