Tubular spring assembly
A tubular spring assembly and a series of tubular spring assemblies for use in beds, chairs, or other cushioned surfaces, the tubular spring assembly having a tubular base member, a tubular second member that partially nests and is slidable within the tubular base member, a spring connecting the two tubular members, a ball joint affixed to the exterior of the second member and a pad attached to the ball joint wherein a series of tubular spring assemblies can be arranged within the interior of a bed, chair, or other cushioned surface to provide widely dispersed pressure onto the user.
1. A tubular spring assembly comprising:
a tubular base member, having a first end, a second end, a first opening proximate the first end, a second opening proximate said second end, and a cross member adjacent to the second end and partially within the second opening;
a second tubular member having a first end and a second end, wherein the first end of the second member is partially enclosed and slidable within the base member;
a spring mechanism having an axle, a drum attached to the axle, and a spring having a first end and a second end, wherein the first end of the spring is attached to the cross member of the base member, and the second end of the spring is attached to said drum;
a ball joint attached to the second end of said second member.
2. The tubular spring assembly of claim 1 , wherein in a pad is attached to the ball joint opposite the second member.
3. The tubular spring assembly of claim 1 , wherein said spring provides 1 pound per square inch of pressure.
4. A series of tubular spring assemblies of claim 1 arranged in a honeycomb pattern.
5. The tubular spring assembly of claim 1 , wherein said tubular base member is hexagonal in shape.
6. The tubular spring assembly of claim 5 , wherein said hexagonal base member comprises:
at least two removable panels, each panel having a first end and a second end, wherein the first end is a rectangular prism and the second end is a rectangular prism shaped receiving volume.
7. The tubular spring assembly of claim 5 , wherein each corner of the hexagonal base member comprises a connector slot having two sides and a receiving volume.
8. The tubular spring assembly of claim 1 , wherein the spring is enclosed within the tubular base member.
9. The tubular spring assembly of claim 1 , wherein the spring is a flat spiral spring.
10. The tubular spring assembly of claim 1 , wherein the drum is rotatably attached to said axle.
11. A cushion comprising a series of tubular spring assemblies having;
a tubular base member having a first end and a second end, a first opening proximate the first end, a second opening proximate said second end, and a cross member adjacent to the second end and partially within the second opening;
a second tubular member having a first end and a second end, wherein the first end of the second member is partially enclosed and slidable within the base member;
a spring mechanism having an axle, a drum attached to the axle, and a spring having a first end and a second end, wherein the first end of the spring is attached to the cross member of the base member, and the second end of the spring is attached to said drum;
a ball joint attached to the second end of said second member; and
a pad attached to the ball joint.
