Abstract

An overbed table may have a base support frame with at least three casters and a rechargeable battery. A motor housing with a top wall having an opening may be attached to the base support and a telescoping column that is hollow tubular is attached at a bottom end to the motor housing over the opening to extend upwardly. A linear motor is positioned in the motor housing with a linear motor actuator projecting through the opening and into the telescoping housing wherein an extension member of the linear motor actuator is attached at a top end to a slidable table column member of the telescoping housing. Servo housing is attached at a top end of the slidable table column member with a servomechanism attached in the servo housing positioned for a rotating shaft of the servomechanism to engage a circular bracket attached adjacent to a first end of a table wherein the circular bracket is rotatably engaged with the servo housing. The rechargeable battery is in electrical communication with a control processor of a control panel attached adjacent the first end of the table, to the linear motor and to the servomechanism.

Dependent claims

An apparatus for positioning a table over a bed comprising:

an overbed table with a base support frame with at least three casters and a rechargeable battery;
a motor housing attached to a top surface of said base support frame and with a top wall having an opening therein and a telescoping column that is hollow tubular structure attached at a bottom end to said motor housing over said opening to extend upwardly;
a linear motor disposed in said motor housing with a linear motor actuator projecting through said opening and into said telescoping column wherein an extension member of said linear motor actuator is attached at a top end to a slidable table column member of said telescoping column;
a servo housing attached at a top end of said slidable table column member with a servomechanism attached in said servo housing disposed for a rotating shaft of said servomechanism to engage a circular bracket attached adjacent to a first end of said table wherein said circular bracket is rotatably engaged with said servo housing;
and
a control processor in electrical communication with a control panel, and each in communication with said linear motor actuator, said servomechanism and said rechargeable battery.
