Abstract

A leg assembly includes a first leg member and second leg member each having side-to-side width that is greater at the top end than the bottom end and a tapered outer surface. The second leg member has top-to-bottom length different than the top-to-bottom length of the first leg member. The leg members are adapted to connect individually or in combination to a support system such that at least three leg heights are selectably provided. The side-to-side width of the top end of the second leg member is approximately equal to the side-to-side width of the bottom end of the first leg member such that when the top end of the second leg members is connected to the bottom end of the first leg member, the combined leg members have a generally continuously tapered outer surface.

Claims

1. A leg assembly for mounting to a support system, comprising:

a first leg member having a body portion with a top end having a top surface and an opposite bottom end having a bottom surface, the top end having a side-to-side width greater than a side-to-side width of the bottom end, the first leg member further having a tapered outer surface extending between the top and bottom surfaces, the body portion of the first leg member having a first top-to-bottom length defined between the top surface and bottom surface; and

a second leg member having a body portion with a top end having a top surface and an opposite bottom end having a bottom surface, the top end having a side-to-side width greater than a side-to-side width of the bottom end, the second leg member further having a tapered outer surface extending between the top and bottom surfaces, the body portion having a second top-to-bottom length defined between the top surface and bottom surface, the second top-to-bottom length being different than the first top-to-bottom length;

wherein the first and second leg members are adapted to connect individually or in combination to the support system such that at least three leg heights are selectably provided; and

wherein the side-to-side width of the top end of the second leg member is approximately equal to the side-to-side width of the bottom end of the first leg member such that when the top end of the second leg members is connected to the bottom end of the first leg member, the top surface of the second leg member is disposed against the bottom surface of the first leg member and the combined leg members have a generally continuously tapered outer surface.

2. The leg assembly of claim 1, wherein the first and second leg members each have a connecting element extending from the top surface thereof for connecting the leg member to another leg member or to the support system.

3. The leg assembly of claim 2, wherein the body portion of each of the leg members is formed substantially from wood and the connecting elements are formed of metal.

4. The leg assembly of claim 2, wherein:

the first leg member has a receiving opening defined in the bottom surface for receiving the connecting element of the second leg member; and

the second leg member does not have a receiving opening defined in the bottom surface.

5. The leg assembly of claim 2, wherein the connecting elements are threaded elements.

6. The leg assembly of claim 1, wherein the top-to-bottom height of the first leg member is less than the top-to-bottom height of the second leg member.

7. The leg assembly of claim 1, wherein the outer surfaces of the first and second leg members are circular in side-to-side cross section.

8. The leg assembly of claim 1, wherein the support system is a support frame including a base frame and an articulating frame supported by the base frame, the leg members being adapted to connect to the base frame.

9. The leg assembly of claim 1, wherein the support system is a mattress support frame.

10. The leg assembly of claim 1, further comprising a plurality of leg assemblies.

11. A bed foundation, comprising:

a mattress support frame having a base frame and an articulating frame supported on the base frame; and

a plurality of modular leg assemblies, each of the at least one leg assembly comprising;

a first leg member having a body portion with a top end having a top surface and an opposite bottom end having a bottom surface, the top end having a side-to-side width greater than a side-to-side width of the bottom end, the first leg member further having a tapered outer surface extending between the top and bottom surfaces, the body portion of the first leg member having a first top-to-bottom length defined between the top surface and bottom surface; and

a second leg member having a body portion with a top end having a top surface and an opposite bottom end having a bottom surface, the top end having a side-to-side width greater than a side-to-side width of the bottom end, the second leg member further having a tapered outer surface extending between the top and bottom surfaces, the body portion having a second top-to-bottom length defined between the top surface and bottom surface, the second top-to-bottom length being different than the first top-to-bottom length;

wherein a plurality of the first leg members are each connected to the base frame to provide a first leg length for the bed foundation, a plurality of the second leg members are each connected to the base frame to provide a second leg length for the bed foundation, and a plurality of interconnected first and second leg members are connected to the base frame to provide a third leg length greater than the first or second leg length; and

wherein the side-to-side width of the top end of each of the second leg members is approximately equal to the side-to-side width of the bottom end of each of the first leg members such that when the top end of one of the second leg members is connected to the bottom end of one of the first leg members, the top surface of the one of the second leg members is disposed against the bottom surface of the one of the first leg members and the combined leg members have a generally continuously tapered outer surface.

12. A modular leg kit for a bed foundation having a base frame, the modular leg kit comprising;

a plurality of first leg members each having a body portion with a top end having a top surface and an opposite bottom end having a bottom surface, the top end having a side-to-side width greater than a side-to-side width of the bottom end, the first leg member further having a tapered outer surface extending between the top and bottom surfaces, the body portion of the first leg member having a first top-to-bottom length defined between the top surface and bottom surface; and

a plurality of second leg members each having a body portion with a top end having a top surface and an opposite bottom end having a bottom surface, the top end having a side-to-side width greater than a side-to-side width of the bottom end, the second leg member further having a tapered outer surface extending between the top and bottom surfaces, the body portion having a second top-to-bottom length defined between the top surface and bottom surface, the second top-to-bottom length being different than the first top-to-bottom length;

wherein a plurality of the first leg members are each connected to the base frame to provide a first leg length for the adjustable bed foundation, a plurality of the second leg members are each connected to the base frame to provide a second leg length for the adjustable bed foundation, and a plurality of connected together first and second leg members are connected to the base frame to provide a third leg length greater than the first or second leg length; and
