Tiered void cells
The disclosed technology includes tiered void cells which provide protection, comfort, and stability during compression. The tiered void cells may be arranged in vertically stacked columns and include a stroke whereby tiers of a void cell can telescope into adjacent tiers of that void cell, as well as telescope into adjacent tiers of adjacent void cells in a column. Implementations described and claimed herein include a cushioning system comprising an array of tiered void cells, wherein each tiered void cell includes a base portion, a plunger portion, the plunger portion to collapse into the base portion under compression of the cushioning system, and a living hinge elastically connecting an inner perimeter of the base portion to an outer perimeter of the plunger portion.
1. An array of tiered void cells collectively functioning as a cushioning system, the tiered void cells elastically deformable under expected load conditions, wherein each tiered void cell comprises: an elastic base portion; an elastic plunger portion, the elastic plunger portion to repeatedly collapse into the elastic base portion under compression of the tiered void cells; and an elastic living hinge elastically connecting an inner perimeter of the elastic base portion to an outer perimeter of the elastic plunger portion, the elastic living hinge to stretch to effect a collapse of the elastic plunger portion into the elastic base portion under compression of the tiered void cells, wherein the collapse of the elastic plunger portion into the elastic base portion adds depth to the elastic living hinge, and wherein each tiered void cell is fluidly open and communicating with a surrounding environment.
2. The array of tiered void cells of claim 1 , wherein the elastic living hinge includes a depth.
3. The array of tiered void cells of claim 1 , wherein the elastic living hinge includes no depth.
4. The array of tiered void cells of claim 1 , wherein the elastic living hinge has an s-shaped section prior to compression.
5. The array of tiered void cells of claim 1 , wherein each tiered void cell is open to atmosphere.
6. The array of tiered void cells of claim 1 , wherein a portion of the tiered void cells have different force-deflection characteristics than another portion of the tiered void cells.
7. The array of tiered void cells of claim 1 , wherein the array of tiered void cells is stacked vertically in columns, each of the vertical columns are enclosed in an encasing, and the vertical columns are attached to neighboring vertical columns.
8. The array of tiered void cells of claim 7 , wherein each of the vertical columns includes at least three void cells.
9. A tiered void cell that is elastically deformable under expected load conditions and functions as a cushion, the tiered void cell comprising:
a first elastic base portion;
a first elastic plunger portion to repeatedly collapse into the first elastic base portion under compression of the tiered void cell;
a first elastic living hinge to elastically connect an inner perimeter of the first elastic base portion to an outer perimeter of the first elastic plunger portion, the first elastic living hinge to stretch to effect a collapse of the first elastic plunger portion into the first elastic base portion under compression of the tiered void cell, wherein the collapse of the first elastic plunger portion into the first elastic base portion adds depth to the first elastic living hinge;
a second elastic base portion;
a second elastic plunger portion to repeatedly collapse into the second elastic base portion under compression of the tiered void cell; and
a second elastic living hinge to elastically connect an inner perimeter of the second elastic base portion to an outer perimeter of the second elastic plunger portion, the second elastic living hinge to stretch to effect a collapse of the second elastic plunger portion into the second elastic base portion under compression of the tiered void cell, wherein the collapse of the second elastic plunger portion into the second elastic base portion adds depth to the second elastic living hinge, and wherein the tiered void cell is fluidly open and communicating with a surrounding environment.
10. The tiered void cell of claim 9 , wherein the first elastic plunger portion is attached to the second elastic plunger portion.
11. The tiered void cell of claim 9 , wherein the first elastic base portion is attached to the second elastic base portion.
12. The tiered void cell of claim 9 , wherein the first elastic living hinge and the second elastic living hinge each has an s-shaped section.
13. A method of using an array of stacked and opposing tiered void cells collectively functioning as a cushioning system, the tiered void cells elastically deformable under expected load conditions, the method comprising: repeatedly applying a compressive force to the array of tiered void cells; repeatedly collapsing a first elastic plunger portion into a first elastic base portion of a first one of the tiered void cells by stretching a first elastic living hinge elastically connecting an inner perimeter of the first elastic base portion to an outer perimeter of the first elastic plunger portion responsive to the compressive force, wherein the collapsing of the first elastic plunger portion into the first elastic base portion adds depth to the first elastic living hinge; and repeatedly collapsing a second elastic plunger portion into a second elastic base portion of a second one of the tiered void cells opposing the first one of the tiered void cells by deforming a second elastic living hinge elastically connecting an inner perimeter of the second elastic base portion to an outer perimeter of the second elastic plunger portion responsive to the compressive force, wherein the collapsing of the of the second elastic plunger portion into the second elastic base portion adds depth to the second elastic living hinge, and wherein each tiered void cell is fluidly open and communicating with a surrounding environment.
14. The method of claim 13 , further comprising: repeatedly collapsing the first elastic base portion into the second elastic base portion by deforming a third elastic living hinge elastically connecting the inner perimeter of the second elastic base portion to the outer perimeter of the first elastic base portion.
15. The method of claim 13 , wherein the first elastic living hinge and the second elastic living hinge each includes a depth.
16. The method of claim 13 , wherein the first elastic living hinge and the second elastic living hinge each includes no depth.
