Abstract

Adjustable mattress foundations generally include a mattress support surface including a head and back section hingedly connected to an intermediate seat section at one end and a leg and foot section hingedly connected to the intermediate seat section at another end. The intermediate seat section includes spaced apart upper and lower panels, wherein the lower panel is hingedly connected to the head and back section and slideably engaged with side frame members of the foundation, and wherein the upper panel is stationary and hingedly connected to the leg and foot section. A linear actuator is operatively coupled to a linkage assembly to independently effect inclination or declination of the head and back section relative to the intermediate seat section and is further operative to effect an increase or decrease in a length of the intermediate seat section by movement of the lower panel relative to the upper panel.

First claim

What is claimed is:

1. An adjustable foundation and mattress assembly, comprising:
a mattress having a top surface, a bottom surface, and an inner core between the top surface and the bottom surface, wherein the mattress has a width and a length; and
an adjustable foundation for supporting the bottom surface of the mattress, the adjustable foundation comprising a foundation frame and an oversized deck attached to the foundation frame, wherein the deck has a width and a length that is substantially identical to the width and the length of the mattress and the foundation frame has a width that is less than the width of the mattress and a length that is substantially identical to the length of the mattress,
wherein the oversized deck comprises a mattress support surface including a head and back section hingedly connected to an intermediate seat section at one end and a leg and foot section hingedly connected to the intermediate seat section at another end, wherein the intermediate seat section includes a separate first portion and a separate second portion, wherein the first portion is hingedly connected to the head and back section and the second portion is hingedly connected to the leg and foot section.

2. The adjustable foundation and mattress assembly of claim 1 , wherein the length and width of the deck is substantially identical to a king sized mattress and the length and width of the foundation is substantially identical to a queen sized mattress.

3. The adjustable foundation and mattress assembly of claim 1 , deck comprises a laminated honeycomb material.

4. The adjustable foundation and mattress assembly of claim 1 , deck comprises a structural foam.

5. The adjustable foundation and mattress assembly of claim 1 , wherein the foundation frame comprises side frame members and transverse frame members attached at respective ends to define a generally rectangular shape; and wherein the first portion of the intermediate seat section is an upper panel and the second portion is a lower panel spaced apart from the upper panel, wherein the lower panel is hingedly connected to the head and back section and slidably engaged with the side frame members, and wherein the upper panel is stationary and hingedly connected to the leg and foot section; and a first linear actuator having an extending and retracting member operatively coupled to a first linkage assembly to independently effect inclination or declination of the head and back section relative to the intermediate seat section, wherein the first linear actuator is further operative to effect an increase or decrease in a length of the intermediate seat section by movement of the lower panel relative to the upper panel.

6. The adjustable mattress foundation of claim 5 , further comprising:
a second linear actuator having an extending and retracting member operatively coupled to a second linkage assembly to independently effect inclination or declination of the foot and leg section.

7. The adjustable mattress foundation of claim 5 , wherein the side frame member is an angle iron having an L-shaped cross section, and wherein the lower panel is coupled to a linear slide plate including a channel adapted to slideably engage a portion of the L-shaped cross section.

8. The adjustable mattress foundation of claim 5 , wherein the upper panel is spaced apart from the lower panel by a spacer.

9. The adjustable mattress foundation of claim 5 , wherein the head and back section comprises a single panel, and the leg and foot section comprises a first panel hingeably connected to a second panel.

10. A process for operating an adjustable mattress foundation, the process comprising:
changing a position of a head and back section relative to an intermediate seat section of an adjustable mattress foundation, the adjustable mattress foundation comprising a foundation frame comprising side frame members and transverse frame members attached at respective ends of the side frame members to define a generally rectangular shape; a mattress support surface including the head and back section, the intermediate seat section and a leg and foot section, wherein the intermediate seat section includes an upper panel and a lower panel spaced apart from the upper panel, wherein the lower panel is hingedly connected to the head and back section and slidably engaged with the side frame members, and wherein the upper panel is stationary and hingedly connected to the leg and foot section; and a first linear actuator having an extending and retracting member operatively coupled to a first linkage assembly to independently effect inclination or declination of the head and back section relative to the intermediate seat section, wherein the first linear actuator is further operative to effect an increase or decrease in a length of the intermediate seat section by movement of the lower panel relative to the upper panel; and
lengthening the intermediate seat section upon inclining the head and back section by moving the first portion away from the second portion; or
shortening the intermediate seat section upon declining the head and back section by moving the first portion towards the second portion.

11. The process of claim 10 , wherein changing the position of the head and back section relative to the intermediate seat section simultaneously changes a position of the leg and foot section relative to the intermediate seat section.

12. The process of claim 10 , wherein simultaneously changing the positions of the head and back section and the leg and foot section comprises actuating a second actuator operatively coupled and linked thereto.

13. The process of claim 10 , wherein changing the position of the head and back section relative to the intermediate seat section is independent from changing a position of the leg and foot section.

14. The process of claim 10 , wherein lengthening the intermediate seat section causes the head and back section to slide towards a head end of the adjustable mattress foundation.

15. An adjustable mattress foundation, comprising:
a foundation frame comprising side frame members and transverse frame members attached at respective ends with a corner bracket to define a generally rectangular shape, the corner bracket at an angle of about 45 degrees between the respective ends of the side frame members and the transverse frame members; and
a foam block coupled to the corner bracket and having an arcuate shaped exterior portion projecting from the corner bracket.
