Abstract
The invention pertains to an improved insole that combines insulating and therapeutic properties. The insole consists of a sandwich of several materials, namely a mesh that is adapted to rest on the bottom of some footwear, an aluminum foil whose shiny face is fixed with an adhesive on the top face of the mesh. A polyethylene film laminated against the dull face of the aluminum foil also serves as the external face of an air bubble sandwich made out of one or two rows of air cells, separated from each other by a central polyethylene film, and covered by another polyethylene film. A second aluminum foil has its dull face laminated against a polyethylene film, and a mesh is then fixed on the shiny surface of the aluminum film with an adhesive. Finally, a resting strip for a foot is then fixed, by an adhesive to the top of the mesh.
Description
SPECIFICATION
TITLE: THERAPEUTIC AND INSULATING INSOLE
1) Background-Field of the invention:
This invention relates to insoles, specifically to such insoles that have therapeutic uses and insulate one's foot.
2) Background-Description of Prior Art:
A certain number of insoles are presently on the market and the following patents have been found of interest:
* SHO 19201 Kieren, 4 February 1983, which illustrates an insole comprising: a row of isolated air cells which are covered by a protective lining on its internal and external sides. This insole does not insulate the foot well against the cold and humidity over a long period of use. The insole will flatten very rapidly because it is not very thick.
* SW 227,135 Olsson, 5 August 1968, which illustrates an insole comprising a number of different density foam layers and a thin layer of metal mesh on its superior face.
* EP 0,452,576, Al Chen, 18 April 1990, which illustrates a number of laminated air cells layers having a film between each of the air cells layers. Certain films may be made of metal and some layers of air cells may be connected to each other. This invention possesses an aluminum coating on the inside but does not provide aeration means on the surface of the insole.
* US 4,999,931 Vermeulem, 19 Mars 1991, which illustrates a system to absorb shocks in an insole. The invention reveals air cells " drowned " in a polymer or a foam which, by their density, absorb a big portion of the shocks, but do not repell humidity very efficiently.
* US 3,253,601 Scholl, 31 Mai 1966, which illustrates an insole made of a number of layers of different density foams having open cells. This insole has the undesired effect of compressing itself with time and offering minimal shock absorption.
* CN 505,416 Mainville, 21 Mars 1953, which illustrates an insole made out of a
polymer and made only of interlaced filaments and forming a net. This method does not absorb shocks and does not have insulating capabilities.
* FR 969,914 Interrub 31 May 1950, which illustrates an insole made out of different layers of foam where one is porous and adapted to absorb shocks. This insole offers insulation but requires a wide thickness.
* One also finds a material of the Rogers company named PORON 4000 which is an urethane type foam that has a variable porosity. The cells of the material are open which allows the material to breath. The material by itself offers an insole of various hardness values according to composition but used alone, it does not provide adequate insulation.
Objects and Advantages:
Accordingly, besides the objects and advantages of the therapeutic and insulating insole described in my present patent, several objects and advantages of the present invention are:
(a) a better absorption of shocks on the foot,
(b) a better support of the foot because some of the air cells are compressed so the insole takes the form of the foot;
(c) a better insulating capability because of the combination of aluminum coating and air cells;
(d) a better therapeutic insole for people having problems with sweating feet and a better blood circulation because of the reflective effect of the aluminum film. The foot muscles get dilated, which permits a better blood circulation and at the same time reduces numbness and pain in the foot and the legs.
A primary objective and more specific object of the invention is to provide an insole that adapts to the foot and comprises openings that permit the passage of energy emissions coming from the foot, a reflective aluminum film adapted to the base of the insole and allowing the reflection of energy through the opening and back toward the foot. The presence of a mesh between the insole and the aluminum film allows a certain space which gives a better reflective effectivness by the aluminum film and reinforces the air insole so as to prolong its life.
A second objective is to provide a mean of air cells attached to the aluminum film which give an insole to absorb shocks so that the air cells do not collapse under the pressure exerted by the foot. The air cells comprise a polyethylene film welded to the aluminum film on its dull surface.
A third objective is to provide a reflective mean adapted to the air cells and comprising an aluminum film which possesses a reflective side which radiates the energy emissions coming from a footwear sole, back to the footwear sole and keeping the foot at an appropriate temperature.
Still further objects and advantages will become apparent from a consideration of the ensuing description and drawings.

Description
A typical embodiment of the insole of the present invention is illustrated in fig.l where one can see: a first mesh 20 composed of an interior face 22 made out of narrow thongs 24 ( fig. 2A) parallel, and an exterior face 26 made out of large thongs 28 parallel, placed peφendicularly to the narrow thongs 24 and fixed to the latter by means of thermowelding 29. The external face 26 is fixed, by adhesive means 30, to a first reflective face 31 ( fig.3) of a first aluminum film 32 possessing a second opposed face 34 (fig. 1) located at the back of the first reflective face 31 of the first aluminum film 32. The second opposed face 34 has a dull appearance and is fixed, at the time of the production of the aluminum by cold drawing, to a
first polyethylene film 40 by cold laminating. The first aluminum film 32 forms the exterior of a double air bubbles sandwich 38 (fig. 4 ). The air bubble sandwich 38 comes from a manufacturing process implicating lamination of two polyethylene films with aluminum foil; a first reflective aluminum film on an exterior side and a polyethylene film on the dull side, on the interior, a second aluminum film identical to the first and also having the reflective side toward the exterior with the polyethylene film on the dull side. Between the two aluminum foils, a double row of air bubbles separated in the center by a polyethylene film joining the two rows of air bubbles. The sandwich 38 comprises a first polyethylene film 40 having an internal face 36 and first opposed contact face 42.
A first serie of air cells 44, having an approximative diameter of 10 mm, disposed at a rate of less than 1 air cell per cm_2 or less than 100 air cells by square decimeter are fixed, by means of thermowelding 29, to the first opposed contact face 42. A second central film 46 joins, by means of thermowelding 48, the first serie of air cells 44 to a second serie of air cells 50 . The latter is affixed to a third polyethylene film 52, having a second opposed contact face 54 and an external face 56, by means of thermowelding 29, to the second opposed contact face 54. The external face 56 of the third polyethylene film 52, which is also the external face of the sandwich 38, is fixed, by adhesive means 30, on a third face 58 (fig.l) of a second aluminum film 60 having a fourth reflective face 62 at the back of the third face 58. The fourth reflective face 62 is affixed, by adhesive means, to a bottom face 64 of a second mesh 66. There exists the possibility of utilising only one row of air cells in the sandwich ( fig. 3), or two rows ( fig. 4) in an amount of 1 to 10 cells to a cm2. Nevertheless studies show that two rows of air cells ( fig. 4) are more effective and improve by far, the advantages of the present invention. The second mesh 66 has a bottom face 64 ( fig. 2B) which comprises second narrow thongs 68 that are parallel and are fixed, by means of thermowelding 29, onto second large thongs 70, parallel between them and peφendicular to the second narrow thongs 68 forming thus the second ports 71. The second large thongs 70 constitute the top face 72 of the second mesh 66. The top face 72 is fixed, by adhesive means 30, to an inferior face 78 of a fabric means which is a tissue 74 which also possesses a superior face 80 having a serie of first ports 76 permitting the ventilation of the insole. The ports have an ideal diameter of 1mm but can vary from 0.5 mm to 2 mm and represent an area of up to 20% of the total area of the insole. The 20% limit is there to prevent the insole from caving and not to be able to support adequatly the foot. Also the bigger the holes, the greater the risk of sweat touching the aluminuin and, because of its acidity, causing rust to appear on
the aluminum. The mesh forms a netting having a size that can vary from 1 mm X 1 mm to about 6 mm X 6mm. The tissue 74 that rests under the foot can be made from a spongy material which comprises the following materials: Poron, spongy neoprene, latex, rubber, latex foam, viscolastic solid. In the case where the spongy material is used, the air bubbles are disposed as in a sponge. The tissue which rests on the first mesh has a thickness not exceeding 6 mm and is constant on the whole of the length of the insole. The porosity resulting from the opened cells inside the tissue means, is constant over the whole volume of the tissue means. The elasticity of the tissue 74 means corresponds to a 25/50 durometer hardness. Also, the tissue 74 possesses orifices wherein the amount of orifices can vary up to an area that represents 15% of the surface of the insole. The ideal diameter of the orifices is 1mm but it can vary from 0.5 mm to 2 mm. In the process of laminating aluminum to polyethylene, the dull surface of the aluminum film is fixed, by means of adhesive, onto a polyethylene film. The aluminum film has a tickness that can vary from 0.005 mm to 0.1 mm and is made of aluminum having a purity level that can vary from 99.25 % to 99.99%. The bottom face 64 of first mesh 20 and the exterior face 26 of second mesh 66 are fixed respectivly, by cold laminating, onto the fourth 62 and first 31 reflective faces of the aluminum films.
Although the above description contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given. Nevertheless studies show that two rows of air bubbles (fig. 3) and more (fig. 4) are more effective and improve by for, the advantages of the present invention. The air bubbles can be also constituted of spongy materials, comprising the following materials: Poron, spongy, neoprene, latex, rubber, foam, polyester, viscoelastic solid. The aluminum film has a thickness that can vary from 0.005 mm to 0.1 mm and is made of aluminum having a purity level that can vary from 99.25% to 99.99%.
