Abstract

COMPOSITE SHEET MATERIAL
ABSTRACT OF THE DISCLOSURE

A composite sheet material which yields under non-uniform pressures caused by irregularities of contact between two relatively hard surfaces adapted to provide a more uni-form pressure distribution comprising the combination of relatively small granules and relatively small stiff fibers in a matrix of waxy material adhered to a web of flexible material.

Description

20~)30~33 BACKGROUND OF THE INVENTION
~ . _ .
The present .'nvention relates to a sheet material for primary use as sh~e insoles.
Before the present invention, shoe insoles of various materials were shown ~or placement against the lower surface of the feet. Such ingoles gradually deform by simple loadir.g and do not relieve the pressure points caused by the uneven contact between the foot and the insole. Eventually insoles do permanently deform due to the deterioration of the insole material over time in response to the continued loading of the material. A fitting pad is disclosed in U.S. Patent 4,255,202.

SUMMARY OF THE INVENTION

A principal feature of the present invention is the provision of an improved sheet of material which deforms to a shape which smooths out pressure distribution between the foot and the insole in a relatively short time.
In one embodiment, the sheet material of the invention comprises, a laminate having a plurality of layers comprising a carrier fabric coated on both sides by a waxy material, relatively small granule~ in the waxy material, and relatively stiff small fiberq in the waxy material.
In another embodiment, the sheet material comprises a batt of relatively stiff small fibers havin~ disposed therein hollow glass or plastic microspheres and a matrix of waxy material being bonded to a covered sheet.
A feature of the present invention is that the sheet material may be shaped for use as the insole of a shoe.
A further feature of the pres0nt invention i5 that the fibers and granules may move upon the application of pressures, and yield to fnrm ~ relatively permanent irrogular layor _ I ~

20~3083 .
to reduce the forces between the foot and the insole after a short period of time.
Still another feature of the invention is that the fibers and granules become fixed in relation to each other after application of pressure, and the sheet material has been shaped by use, and the fiber~ and granules retain their relationship and the sheet retains its shape until different forces are applied.
Thus ,: a feature of the present invention is that the material quickly conforms to reduce or eliminate the pressure points preceived in the contact of the foot and against the insole sheet material.
A feature of the present invention is that when used as an insole, the sheet material provides an "old used-shoe" feel after a relatively short period of time.
Further features will become more fully apparent in the following description of th~ embodiments of thi-~ in-vention and from the appended claims.

DESCRIPTION OF THE PREFERRED EM~ODIMENTS

Referring now to Figs. l and 2, there is shown a foot S 10 having its skeletal bones 12 indicated and the support platform 14 which may comprise any known midsole/outsole combina-tion. Interposed between the foot and the support platform is a sheet of material 16 which serves as an insole. As shown in Fig. 1, insole 16 is of essentially uniform thickness.
When the shoe is loaded by having foot 10 forced against insole 16 on support platform 14, as shown in Fig. 2, the in~ole 16 deforms and has areas of non-uniform thickness to account for an equalization of pressures from the foot as shown by deformed area 18 under the metatar~al arch l9 and the essentially non-de~ormed area under the fatty portion 20 of the foot.
Referring now to Fig. 3, there is shown the sheet material 24 of one embodiment of the present invention. The sheet material 24 comprises a laminate 26 o~ a plurality of individual layers or plies 28 which are placed against each other in the sheet material 24.
Each of the layers 28 comprises a central carrier fabric 30, such as a woven, knitted, nonwoven, or scrim material. In a suitable form, the carrier fabric 30 may comprise a nonwoven material sold under product No. LYl43089 by the ~endall Company of 25 ~08ton, Mas~achu~et~.

Both sides of the carrier fabric 30 aL@ coated by a waxy or adhesive material 32, such as a low molecular weight hydrocarbon or para~fin, which has a relatively low melting point, such as 200~. The waxy material 3~ is sprayed or laid in molten 20[)3083 form onto opposed sides of the carrier fabric 30, and the carrier fabric 30 may be any suitable material which will hold the ~iaxy material 32. ~he waxy material 32 holds the laminate 26 together during use.
S As shown, a plurality of granules 34 are placed in the waxy material 32 in its molten condition. The granuleq 34 may comprise hollow glass microspheres, plastic microspheres, or bubbles preferably having a diameter of less than 100 micron~.
~lthough the granules 34 are shown on one side of the carrier fabric 30, it is understood that the granules 34 may be placed on both sides of the carxier fabric 30.
A plurality of chopped stiff fibers or flock 36 are also placed in the waxy material 32 in its molten condition.
The fibers 36 may comprise a suitable fiber such as Dacron, a trademark of E.I. duPont de t~emours. Although the fibers 36 are shown a~ being placed on one side of the carrier fabric 30, it will be understood that the fibers 36 may be placed on both sides of the fabric 30 in the waxy material 32. I'hus, . both the granules 3'1 and fibers 36 are placed in the waxy material 32 while it is in a softened condition, after which the waxy material 3~ is allowed to solidify.
The laminate 26 may comprise any suitable number of layers, such as about 10 plies whlch are placed against each other. The laminate 26 may have durable opposed outer covering layer~ 38, such as a suitable nonwoven material. The resultant sheet material may have a thicknes~ of about 1/8 inch.
During use, the sheet material 24 deforms responsive to the application of pres~ure in order to eliminate the pressure points between the foot 10 and the midsole/outsole formation 14 by the movement of the granules and flock within th~ insole 16 for the shoe. In thi3 manner, the sheet mater-ial 24 ~rovides a comforta~le fecl for tho foot in a rclativcly short period of time. The granules 34 or micropheres provide lightness for the sheet material 24 and are permitted to move around in the waxy material 32 upon the application of pressure.
The granules take up space in the waxy material 32, have a high 5 strength, and do not break under the application of loads.
Responsive to the the application of pressure, ~he granules 34 become closely packed, and quickly provide an old shoe feel for theinsole 1~. Of course, during the application o~ pressure, the microspheres 34 flow or move in the waxy material 32.
Also, during use, the fibers or flock 36, which may be chopped, interlock, and when weight causes heat to build up in the waxy material 32 which melts somewhat and allows the fibers 36, a~ well as the granules 34, to move in the laminate 26. The fibers 36 provide strength to the laminate 26, and the fibers migrate and interlock such that they mat up in the deformed sheet material 24.
In this manner, the sheet material 24 yields to pressure in a relatively short period of time, such aR a .~ew hours.~ The sheet material 24 deforms to the pressure pro-file of the foot, and does not move back to the originalshape in order to provide comfort and cushioning for the foot. The sheet will adjust, however, to different pressure profiles taken by the foot. ~hus, the fillers comprising the granules 34 and flbers 36 interlock upon the applica-tion of pressure for a relatively short period of time, inorder to provide conformability by the sheet material 24 to the pressure points.
Turning now to Flg. 4-6, another embodiment of the invention is illustrated in the sequense in which the composite sheet iY manu~actured.

.

The composite sheet 50 comprises a single consolidated web having a bondable cover sheet 40 which is relatively imper-vious to the migration of the waxy or adhesive material to which i~ adhered a batt 42 of fibrous materials. As shown in Pig. 4, fi~ers 44 are loosely- packed giving the batt a low bulk density.
Fig. 5 shows the batt 42 bonded to co~er sheet 40 by means of adhesive layer 46 and having granules or micro-spheres 48 dispensed therein.
Fig. 6 shows the composite after hot wax has been sprayed on the batt 42, wicking through the fibers causing the fibers 44 and the granules or microspheres 48 to pack down to form a sheet of material suitable for use in shoe insoles.
The foregoing description is given for clearness of under~tanding only, and no unnecessary limitations should be understood therefrom, as modifications will be obvious to those skilled in the art.
