20100183847 | Alternating pattern gel cushioning elements and related methods - An alternating pattern gel cushioning device and methods for making the same. The gel pattern may be two or three dimensional. The devices may be zoned or stacked. The device may be made by a variety of methods including roller molding, open face molding, injection molding, casting, extrusion, compression molding and other methods. | 07-22-2010 |
20120015151 | ALTERNATING PATTERN GEL CUSHIONING ELEMENTS AND RELATED METHODS - Gel cushioning elements may comprise a sheet of elastomeric gel. The sheet may be shaped and configured to define recesses aligned with and extending into corresponding protrusions. The protrusions are configured to buckle in response to a pressure greater than a threshold pressure. Methods of forming a gel cushioning element may comprise disposing elastomeric gel between two molds having elevated features to impart an alternating pattern to the elastomeric gel, and hardening the elastomeric gel to form a sheet defining a plurality of protrusions. Elevated features of one mold may face elevated features of the other mold, and each elevated feature of one mold may be adjacent an elevated feature of the other mold. A portion of the sheet may be configured to buckle in response to a pressure greater than a threshold pressure. A cushion may comprise a gel cushioning element and fabric bonded to the gel cushioning element. | 01-19-2012 |
20120031800 | GEL PUTTIES, ARTICLES COMPRISING SAME, AND METHODS OF FORMING SUCH GEL PUTTIES AND ARTICLES - A healable gel putty may comprise an elastomeric polymer and a plasticizer. The elastomeric polymer may have a melt mass-flow rate in a range extending from about 2 g/10 min to about 100 g/10 min. A weight ratio of the plasticizer to the elastomeric polymer may be from about 1-to-1 to about 50-to-1. An article of manufacture may comprise gel putty disposed in a flexible container. A method of forming gel putty may comprise forming a mixture comprising an elastomeric polymer and a plasticizer. An article of manufacture may be formed by disposing gel putty within a flexible container. | 02-09-2012 |

20120244312 | BREATHABLE GEL - Cushioning elements include a breathable material configured to allow gases to pass through at least a portion thereof, and a plurality of discrete segments of thermoplastic elastomeric gel (“gel”) heat-fused or otherwise attached to the breathable material. The gel comprises an elastomeric polymer and a plasticizer, with a plasticizer-to-polymer ratio of from about 0.3 to about 50. The plurality of discrete segments defines at least one breathable gap between adjacent discrete segments. Methods of forming cushioning elements include forming a plurality of discrete segments of gel, securing each segment to a breathable material, and providing a gas path through the breathable material and between adjacent segments. Another method includes providing molten gel within a mold, providing at least a second portion of the gel within a permeable material, and solidifying the gel to form discrete segments of gel. | 09-27-2012 |
20120276339 | CUSHIONING ELEMENTS COMPRISING ELASTOMERIC MATERIAL AND METHODS OF FORMING SAME - Cushioning elements include a porous foam comprising a series of interconnected cell walls and an elastomeric material formed over at least a portion of the interconnected cell walls. The porous foam is configured to allow gases to pass through at least a portion thereof. Methods of forming cushioning elements may include coating interconnected cell walls of a breathable porous foam with a liquid comprising an elastomeric material, solidifying at least a portion of the elastomeric material, and providing a gas path through the elastomeric material. Other methods include pressing sheets of foam together at a pinch point, disposing a liquid between the foam over the pinch point, coating the foam with the liquid, and separating the sheets beyond the pinch point. Some methods include consolidating a plurality of portions of porous foam into a continuous cushioning material. | 11-01-2012 |
20130043628 | CUSHIONING ELEMENTS COMPRISING BUCKLING WALLS AND METHODS OF FORMING SUCH CUSHIONING ELEMENTS - Cushioning elements having a top cushioning surface and a bottom base surface include an elastomeric cushion member and a stabilizing material. The elastomeric cushion member includes a first plurality of interconnected buckling walls having a first mean height and a second plurality of buckling walls having a second mean height. Each buckling wall of the second plurality intersects and connects to at least two buckling walls of the first plurality. A surface of the stabilizing material on a side thereof opposite the elastomeric cushion member defines the bottom base surface of the cushioning element. The first ends of the first plurality of interconnected buckling walls and the first ends of the second plurality of buckling walls define the top cushioning surface of the cushioning element. Methods of forming cushioning elements include securing a stabilizing material to ends of the first plurality of interconnected buckling walls. | 02-21-2013 |
20140183789 | SMALL FOOTPRINT APPARATUS, METHOD, AND TOOLING FOR MOLDING LARGE THERMOPLASTIC PARTS - A molding system includes a plurality of injection heads each configured to inject molten polymer into a mold cavity. Each injection head has an outer body, a piston disposed within the outer body and defining a polymer chamber on a first side of the piston and a pressure chamber on an opposite second side of the piston. The piston moves from a retracted position to an extended position responsive to pressurization of the pressure chamber. Molten polymer is injected from the polymer chamber into the mold cavity as the piston moves from the retracted position to the extended position. Such systems may be used to mold relatively large articles of manufacture. | 07-03-2014 |
