초록 ▼

Disclosed is a breathable insole heater element (12, 40) for footwear. The heater element is formed by photochemically etching a porous metallized fabric, e.g. nickel-metallized polyester woven fabric. The heater element is embedded in or laminated in an insole for an article of footwear such as a shoe or boot. The insole may be cut to size as desired. The insole may include microencapsulated agents such as fragrances, perfumes, microbials or insect repellents. The microcapsules may be activated to release the agents due to the heat generated by the heater element in operation.

대표청구항 ▼

1. A breathable insole heater element for footwear, comprising: a flexible metallised substrate of porous fabric having a plurality of components each encapsulated with metal wherein the metal on the metallised substrate of fabric is photochemically etched to form the breathable insole heater element by selectively etching out metal encapsulated about the plurality of components of the substrate of porous metallised fabric;a layer of insole face fabric;a backing layer; the flexible metallised substrate being laminated between the layer of insole face fabric and the backing layer; the face fabric being attached to the flexible metallised substrate by a thermoplastic web;whereby the flexible metallised substrate is configured to provide an insole heater element that is porous and breathable. 2. An insole heater element according to claim 1 wherein the pattern of the heater element is selected so that a first part of the heater element provides a different heat output in use to that of a second part of the heater element. 3. An insole heater element according to claim 1 having a thermal protection device to provide temperature control of the heater element. 4. An insole heater element according to claim 3 wherein the thermal protection device is a surface mounted thermistor. 5. An insole heater element according to claim 1 wherein the metallised fabric is coated with a continuous layer of metal. 6. An insole heater element according to claim 1 wherein the components of the substrate of porous metallised fabric are individual yarns, the individual yarns being encapsulated in metal prior to manufacture of the substrate of porous metallised fabric. 7. An insole heater element according to claim 1 wherein the fabric is selected from the group consisting of woven, non-woven, knitted, laminated composite, pressed felt, and braid fabrics. 8. An insole heater element according to claim 1 wherein the components of the substrate of porous metallised fabric are woven polyester threads and the metal is nickel. 9. An insole heater element according to claim 1, further comprising: termination pads for connection of the heater element to a power supply/control system. 10. An insole heater element according to claim 1, further comprising: a flexible fabric connection member for protruding from the final insole so as to provide connection of the heater element to a power supply/control system. 11. An insole heater element according to claim 1 wherein the flexible metallised substrate is formed integrally with a component of the insole heater element. 12. An insole heater element according to claim 1 wherein the flexible metallised substrate extends substantially the full length of the insole heater element. 13. An insole heater element according to claim 1 wherein the flexible metallised substrate is configured so that the insole heater element can be cut or trimmed to one of several possible shapes or sizes to fit an article of footwear without adversely affecting the operation of the insole heater element. 14. An insole heater element according to claim 1 having heat-activatable agents for release due to heat generated by the insole heater element. 15. An insole heater element according to claim 14 wherein the agents are selected from antimicrobials, insect repellents, fragrances, perfumes. 16. An insole heater element according to claim 14 wherein the agents are microencapsulated in microcapsules. 17. An insole heater element according to claim 16 wherein the microcapsules melt at an initiation temperature. 18. An insole heater element according to claim 16 wherein the microcapsules allow diffusion of the agent through their walls to effect a slow release mechanism within the insole heater element at an initiation temperature. 19. The insole heater element according to claim 1 wherein the components of the substrate of porous metallised fabric are individual fibres, the individual fibres being encapsulated in metal prior to the manufacture of the substrate of porous metallised fabric. 20. The insole heater element according to claim 1 wherein the components of the substrate of porous metallised fabric are individual yarns, the individual yarns being encapsulated in metal after manufacture of a substrate of a porous fabric to form the substrate of porous metallised fabric. 21. The insole heater element according to claim 1 wherein the components of the substrate of porous metallised fabric are individual fibres, the individual fibres being encapsulated in metal after manufacture of a substrate of a porous fabric to form the substrate of porous metallised fabric.
