Cushion bladder with middle layer having gaps and various positioned interior welds
View Patent ↗A cushioning device has a first material and an opposing second material that are sealed together at the peripheral edges to form a first (right) side, a first (head) end, a second (left) side, and a second (foot) end. Positioned between the first material and the second material is a middle material. The middle material has a top side, a bottom side, a first gap between the first side and the middle material and a second gap between the second side and the middle material. In addition, the first material is sealed to the middle material's top side at a first set of locations to form a first set of interior welds. The second surface is sealed to the middle material's bottom surface at a second set of locations to form a second set of interior welds. The first set of interior welds on the middle material's top surface and the second set of interior welds on the middle material's bottom surface are not superimposed on each other or overlap each other.
1. A cushioning device comprising:
a first surface having a first perimeter edge and a second surface having a second perimeter edge wherein the first perimeter edge and the second perimeter edge are sealed together to form a first side, a head end, a second side and a foot end;
a middle material
(a) is positioned between the first surface and the second surface,
(b) is connected to the head end,
(c) is connected to the foot end,
(c) is not connected to the first side and has a first gap area between the middle material and the first side,
(d) is not connected to the second side and has a second gap area between the middle material and second side, and
(e) has a top surface and a bottom surface;
the first surface and the middle material's top surface are joined together at a first set of locations to form a first set of interior welds;
the second surface and the middle material bottom surface are joined together at a second set of locations to form a second set of interior welds;
the first set of interior welds on the middle material's top surface and the second set of interior welds on the middle material's bottom surface are not superimposed on each other or overlap each other.
2. The cushioning device of claim 1 wherein the first set of interior welds includes button welds.
3. The cushioning device of claim 1 further comprising a connector to receive a fluid.
4. The cushioning device of claim 3 wherein the fluid is air.
5. The cushioning device of claim 3 further comprising a pump that delivers the fluid to the connector.
6. The cushioning device of claim 1 wherein the first set of interior welds on the middle material's top surface are in a first set of rows.
7. The cushioning device of claim 6 wherein the second set of interior welds on the middle material's bottom surface are in a second set of rows, and the first set of rows and the second set of rows are not superimposed on each other.
8. The cushioning device of claim 7 wherein the first set of rows and the second set of rows are adjacent to each other.
9. The cushioning device of claim 6 wherein the first set of interior welds on the middle material's top surface are in a first set of columns.
10. The cushioning device of claim 9 wherein the second set of interior welds on the middle material's bottom surface are in a second set of columns, and the first set of columns and the second set of columns are not superimposed on each other.
11. The cushioning device of claim 10 wherein the first set of columns and the second set of columns are adjacent to each other.
12. The cushioning device of claim 1 wherein the second set of interior welds includes button welds.
13. The cushioning device of claim 1 wherein the first set of interior welds are button welds.
14. The cushioning device of claim 1 wherein the second set of interior welds are button welds.
15. The cushioning device of claim 1 further comprising
a first bar weld formed between the first surface and the top surface of the middle material through a column of the first set of interior welds and extends from the first side to the second side through the gap areas only for the width of the first bar weld; and
a second bar weld formed between the second surface and the bottom surface of the middle material through a column of the second set of interior welds and extends from the first side to the second side through the gap areas only for the width of the second bar weld.
16. The cushioning device of claim 1 wherein the middle surface is a heat or sonic sealable material to the first surface and the second surface.
17. The cushioning device of claim 1 wherein the first surface is selected from the group consisting of a three-ply puncture-resistant vinyl film, an air impervious flexible material, and a two-ply air impervious flexible material.
18. The cushioning device of claim 1 wherein the second surface is selected from the group consisting of a three-ply puncture-resistant vinyl film, an air impervious flexible material, and a two-ply air impervious flexible material.
19. The cushioning device of claim 1 further comprising at least a first handle area having a first handle aperture and a second handle area having a second handle aperture on the first side or the second side.
