Abstract

A bedding foundation has a linear actuator for moving a roller carriage forward and backwards. The roller carriage includes wheels which move along rails supported below a rigid platform having an opening extending through the platform. The roller carriage includes a lifter which raises and lowers a roller independently of the movement of the linear actuator. Regardless of the position of the linear actuator, the roller may be raised or lowered. The roller moves back and forth inside the opening extending through the rigid platform and imparts a massage movement to a mattress above the foundation.

First claim

What is claimed is:

1. A bedding foundation comprising:
a generally rectangular frame supported by legs, the generally rectangular frame including transversely extending slats extending between hollow frame side members;
a plurality of trays suspended by the slats, a portion of each tray being above adjacent slats;
at least one lift actuator inside each of the trays, each lift actuator raising and lowering a lift plate, wherein said lift actuators are programmed to move the lift plates in a vertical direction in a predetermined pattern,
a pliable platform supported by the generally rectangular frame, the pliable platform having no cutouts or openings therein and being able to move in a wave shape for massage effect; and
a protective shroud surrounding the pliable platform.

2. The bedding foundation of claim 1 , wherein the generally rectangular frame has hollow end members.

3. The bedding foundation of claim 1 , wherein the foundation has at least two lift actuators.

4. The bedding foundation of claim 1 , wherein the lift actuators are programmed to raise and lower the lift plates at predetermined times.

5. A bedding foundation comprising:
a frame supported by legs;
a plurality of slats suspended by the frame;
a plurality of trays suspended by the slats, only one tray being supported by adjacent slats;
at least one lift actuator being secured inside each of the trays, wherein each of the lift actuators is programmed to move in a vertical direction, and
a pliable platform supported by the slats, the pliable platform being able to move in a wave shape for massage effect; and
a protective shroud surrounding the pliable platform.

6. The bedding foundation of claim 5 , further comprising support plates secured to the lift actuators.

7. The bedding foundation of claim 6 , wherein the pliable platform has no cutouts or openings therein.

8. The bedding foundation of claim 6 , wherein the lift actuators are programmed to raise and lower the support plates at predetermined times.

9. The bedding foundation of claim 6 , wherein the support plates are the same size.

10. The bedding foundation of claim 9 , wherein the support plates are rectangular.

11. A method of providing a massaging feeling to a mattress from a bedding foundation, the method comprising:
raising and lowering multiple lift plates using lift actuators, the lift actuators being supported by slats extending between hollow frame side members of a generally rectangular frame supported by legs;
wherein the lift actuators are secured to trays supported by the slats, programmed to raise, and lower the lift plates in a predetermined manner when activated, thereby raising and lowering portions of a pliable platform having no cutouts or openings therein to create a wave shape in the pliable platform.

12. The method of claim 11 , wherein the lift actuators are programmed to raise and lower the lift plates at predetermined times.

13. The method of claim 11 , wherein the lift actuators are in the trays supported by the slats.

14. The method of claim 13 , wherein the trays are spaced from each other.

15. The method of claim 14 , wherein each of the trays holds one lift actuator.
