Abstract
A dampening bearing support member having a plurality of bearings disposed between an object and a base with rheological fluid disposed around the bearings and structure to retain the rheological fluid in such position, with the rheological fluid being under the control of the user at times when it is desired to stiffen the rheological fluid and limit or prevent movement of the bearings and the object in relation to the base.
Claims10
A dampening bearing with an object disposed above said bearing, comprising:
- a base;
- a plurality of bearings disposed between said object and said base;
- a rheological fluid disposed around said bearings, said bearings being disposed within said rheological fluid;
- flexible means to contain said rheological fluid around said bearings, said means disposed between said object and said base;
- and
- means to stiffen said rheological fluid for preventing lateral movement of said bearings and dampening the movement of said object in relation to said base.

A dampening bearing with an object disposed above said bearing, comprising:
- a base;
- a plurality of bearings disposed between said object and said base;
- an electro rheological fluid disposed around said bearings, said bearings being disposed within said electro rheological fluid;
- flexible means to contain said electro rheological fluid around said bearings, said flexible means disposed between said object and said base;
- means to produce an electric current;
- and
- means to pass said electric current through said electro rheological fluid, said electric current means able to be activated when desired for stiffening said electro rheological fluid to prevent lateral movement of said bearings and dampen the movement of said object in relation to said base.

A dampening bearing with an object disposed above said bearing, comprising:
- a base;
- a plurality of bearings disposed between said object and said base;
- an electro rheological fluid disposed around said bearings, said bearings being disposed within said electro rheological fluid;
- flexible means to contain said electro rheological fluid around said bearings, said flexible means disposed between said object and said base;
- means to produce an electric current;
- means to pass said electric current through said electro rheological fluid, said electric current means able to be activated when desired for stiffening said electro rheological fluid to prevent lateral movement of said bearings and dampen the movement of said object in relation to said base;
- an upper electrode plate disposed above said bearings;
- a lower electrode plate disposed under said bearings;
- said flexible means to contain said electro rheological fluid including an elastic member extending from said upper electrode plate to said lower electrode plate;
- said means to produce electric current and pass it through said electro rheological fluid further including a power source having a first and second pole;
- means to connect said first pole to said upper electrode plate;
- means to connect said second pole to said lower electrode plate;
- and
- means to direct current from said power source to said upper electrode plate and lower electrode plate such that said current passes through said electro rheological fluid to cause said electro rheological fluid to stiffen and dampen movement of said object in relation to said base when movement is desired to be dampened.

A dampening bearing with an object disposed above said bearing, comprising:
- a base;
- a plurality of bearings disposed between said object and said base;
- a magneto rheological fluid disposed around said bearings, said bearings being disposed within said magneto rheological fluid;
- flexible means to contain said magneto rheological fluid around said bearings, said flexible means disposed between said object and said base;
- and
- means to produce a magnetic field and pass said magnetic field through said magneto rheological fluid for stiffening said magneto rheological fluid to prevent lateral movement of said bearings and dampen the movement of said object in relation to said base.
3 more elements
A method of dampening movement of a bearing between an object and a base, comprising the steps of:
- placing said bearing within a rheological fluid;
- containing said fluid:
- activating said rheological fluid to stiffen said rheological fluid;
- and
- reducing said movement of said bearing by said stiffened fluid and thereby reducing said movement of said object in relation to said base.
