Abstract
A rocking assembly for a bed has a mattress frame, a base frame and a rocking driver. The base frame supports the mattress frame. The rocking driver is mounted on the base frame and has a motor, a flywheel and a connecting rod. The flywheel is rotated by the motor. The connecting rod is connected eccentrically to the flywheel and pivotally to the mattress frame. When the motor turns, the connecting rod rocks the mattress frame so a person lying on the bed rocks from side to side and pressure on individual parts of the person's body is alleviated so blood can circulate to the areas and bedsores will not develop.

A rocking assembly for a bed comprises
- a base frame having
- multiple transverse members including a central transverse member;
- and
- a mounting bracket mounted on the central transverse member;
- a mattress frame mounted pivotally on the base frame and having
- multiple transverse members including
- an L-shaped foot slat;
- an L-shaped central slat;
- and
- a flat central slat;
- and
- a rotating longitudinal member connected to the mounting bracket on the base frame, allowing the mattress frame to rock relative to the base frame and comprising
- an inner shaft mounted securely between the L-shaped foot slat and the L-shaped central slat and having two ends;
- two bearings mounted around the inner shaft respectively near the ends of the inner shaft;
- and
- an outer tube mounted on the bearings between the L-shaped foot slat and the L-shaped central slat, rotating around the inner shaft and attached to the mounting bracket on the base frame;
- and
- a rocking driver mounted on the base frame, rocking the mattress frame relative to the base frame and comprising
- a motor mounted on the base frame;
- a flywheel connected to and rotated by the motor;
- and
- a connecting rod connected eccentrically to the flywheel and having
