Abstract

An adjustable foundation includes a base frame and an articulating frame movably supported by the base frame for longitudinal movement with respect to the base frame. A mattress platform is positioned on the articulating frame. A concealing assembly is positioned below the mattress platform and at least partially conceals the base frame. The concealing assembly is attached to the articulating frame for simultaneous longitudinal movement therewith.

an actuator connected to the drive end of the drive aim and operable to move the head board portion from the substantially flat position to the at least one substantially raised position by pushing against the drive end of the drive arm.

2. An adjustable bed frame assembly in accordance with claim 1, wherein the side frame members and the middle frame member are connected through a curved frame portion, and the side frame members define a pair of generally parallel side portions.

3. An adjustable bed frame assembly in accordance with claim 2, wherein the middle frame member is disposed between the generally parallel side portions and generally parallel thereto, the first end of the drive arm connected to the middle frame member.

4. An adjustable bed frame assembly in accordance with claim 3, wherein the drive arm has an intermediate portion protruding from each of the spaced-apart sides between the drive end and first end, each of the intermediate portions connected to and engaging and overlapping the middle frame member of the head frame.

5. An adjustable bed frame assembly in accordance with claim 1, wherein the first end of the drive arm is attached to the middle frame member of the head frame within an upper ⅓

of the head portion of the mattress platform, the drive arm being shorter than the middle frame member.

6. An adjustable bed frame assembly in accordance with claim 1, further comprising:

a central frame disposed directly under the central portion of the mattress platform; and

the actuator having a first end and a second end, the actuator being connected to the drive end of the drive arm at the first end of the actuator, the second end of the actuator connected to the central frame.

7. An adjustable bed frame assembly in accordance with claim 6, wherein the actuator has a first component extendable from a second component, the second component being disposed under the central portion of mattress support.

8. An adjustable bed frame assembly in accordance with claim 6, wherein the head frame is pivotally connected to the central frame.

9. An adjustable bed frame assembly in accordance with claim 1, wherein the mattress platform comprises a stationary deck defining the central portion and a foot portion, the head portion being the only movable portion of the mattress platform.

10. An adjustable bed frame assembly in accordance with claim 1, wherein the mattress platform further comprises a foot portion for supporting a foot portion of a mattress, the foot portion being movably relative to the central portion.

11. An adjustable bed frame assembly in accordance with claim 1, wherein the actuator is a push only actuator.

12. An adjustable bed frame assembly in accordance with claim 1, wherein the drive aim is formed from a single piece of sheet metal folded along a longitudinal axis.

13. A head frame for an adjustable bed frame assembly of the type having a mattress support with an adjustably positioned head board portion and a central portion, the head board portion being movable relative to the central portion between a substantially flat position and at least one substantially raised position, the head frame comprising:

a frame member connected to an underside of the head board portion of the mattress support, the frame member having a pair of generally parallel side portions;

a middle frame member having two side surfaces and disposed between the generally parallel side portions and generally parallel thereto; and

a drive arm folded along a longitudinal axis thereby defining two spaced-apart sides and having a generally U-shaped cross section, the drive arm having a first end, the two spaced-apart sides of the first end attached to and engaging and overlapping the two side surfaces of the middle frame member of the head frame adjacent the head board portion, the drive arm further having an opposite drive end spaced from the head board portion, the first end being closer to a head end of the head frame and the drive end being closer to a foot end of the head frame, the drive arm forming an acute angle with the head board portion.

14. A head frame in accordance with claim 13, wherein the frame member of the head frame is a curved frame member defining the pair of generally parallel side portions and a lateral connecting portion.

15. A head frame in accordance with claim 13, wherein the drive arm has an intermediate portion protruding from each of the spaced-apart sides between the drive end and frame end, each of the intermediate portions connected to and engaging and overlapping the middle frame member of the head frame.
