Abstract
A stand for supporting an article a spaced distance above a support surface and for damping vibration therebetween. The stand includes a support frame having resilient bushings engaged therewith. Each bushing defines a bore into which a first end of one of a plurality of rods is received. The rods extend downwardly from the bushings and abut the support surface. The bores are configured to permit the rods to move more in one horizontal direction than in another.
Claims20
A stand for supporting an article vertically above a support surface, said stand comprising:
- a support frame;
- a plurality of isolating assemblies provided on the support frame, each isolating assembly comprising:
- a resilient bushing having a first end and a second end, and having a longitudinal axis extending therebetween
- a longitudinal bore defined in the bushing, said bore having a first end adjacent the first end of the bushing and a second end disposed a distance inwardly from the second end of the bushing;
- wherein the first end of the bore is of a first width measured in a first direction orthogonal to the longitudinal axis and is of a second width measured in a second direction orthogonal to both the longitudinal axis and to the first direction, and the first width is greater than the second width;
- and wherein the second end of the bore has a width that is substantially equal to the second width when measured in both of the first and second directions;
- and
- a plurality of rods, each rod having a first end that is received within the bore of one of the resilient bushings and a second end remote therefrom, and the second end of the rod is adapted to contact the support surface.
In combination:
- a substantially horizontal support surface;
- a stand comprising:
- a support frame;
- a plurality of isolating assemblies provided on the support frame, each isolating assembly comprising:
- a resilient bushing having a first end and a second end, and having a longitudinal axis extending therebetween
- a longitudinal bore defined in the bushing, said bore io having a first end adjacent the first end of the bushing and a second end disposed a distance inwardly from the second end of the bushing;
- wherein the first end of the bore is of a first width measured in a first direction orthogonal to the longitudinal axis and is of a second width measured in a second direction orthogonal to both the longitudinal axis and to the first is direction, and the first width is greater than the second width;
- and wherein the second end of the bore has a width that is substantially equal to the second width when measured in both of the first and second directions;
- and
- a plurality of rods, each rod having a first end and a second end, where the first end is received within the bore of one of the resilient bushings and the second end abuts the support surface and retains the support frame a spaced distance vertically above the support surface.
The combination as defined in claim 18, wherein each rod has a length as measured between its first and second ends, and the length is between one half inch and two inches.
