Abstract
A device contains a super absorbent hydrophilic polymer in combination with a compatible liquid to form a thick, viscous gel-like colloidal fluid to provide high durability, low cost, and ready manufacture in footwear, medical applications, including surgical padding, flotation sleeping devices, and other applications for the dissipation of shock or load over time and/or an area.
Claims7
A shock absorption or load distribution device comprising:
- a distortable or volume displaceable compartment for absorbing mechanical energy or distributing a load over an area and sealingly retaining a fluid therein;
- and
- a compatible liquid absorbed by a super absorbent hydrophilic polymer forming a viscous colloidal fluid of a desired and controllable viscosity, wherein the desired and controllable viscosity is adjustable within a range of selectable viscosities by regulation of the ratio of the compatible liquid to the super absorbent hydrophilic polymer;
- the compartment being filled with the viscous colloidal fluid to form the shock absorbing or load distribution device.
A shock absorption or load distribution device comprising:
- a cavity having a resilient outer membrane;
- and
- a compatible liquid absorbed by a super absorbent hydrophilic polymer forming a viscous colloidal fluid of a desired and controllable viscosity, wherein the desired and controllable viscosity is adjustable within a range of selectable viscosities by regulation of the ratio of the compatible liquid to the super absorbent hydrophilic polymer;
- the cavity sealingly containing the viscous colloidal fluid to form the shock absorbing or load distribution device.
A shock absorbing or load dissipation device comprising a flexible enclosure means for containing a liquid and a viscous colloid of a desired and controllable viscosity within the enclosure means,
- the viscous colloid comprising a super absorbent hydrophilic polymer and a compatible liquid mixed therewith;
- the super absorbent hydrophilic polymer absorbing the compatible liquid to form the viscous colloid of the desired and controllable viscosity within a range of selectable viscosities by regulation of the ratio of the compatible liquid to the super absorbent hydrophilic polymer.
