Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a compressible/resilient structure for various uses such as, for example, athletic shoes, regular shoes, boots, floor carpets, carpet pads, sports floors etc. The structure itself can be the final product or the structure can be a component of another structure. Uses envisioned include, but are not limited to: automobile parts and other composites; flooring; subfloors especially in gymnasiums or other sports arenas; press pads; ballistic cloth such as body armor or hurricane window protection; sporting equipment padding such as baseball catcher chest protectors; knee/elbow pads for runners, racers, skaters, volleyball players; cricket shin/knee pads; football hip pads; wall padding in stadiums, gymnasiums, arenas; shoe inserts (orthotics); heels/soles for athletic shoes e.g. running shoes; cushioning layer for bedding, vehicle seats, pillows; and other industrial uses where through thickness compressibility and resiliency is required.

Description of Prior Art

While composites are usually a fiber reinforced resin matrix that is rigid and incompressible in all dimensions, certain uses such as for automobile bumpers require some flexibility and shock absorbing capability, plus the ability to return to the original shape once an impact force is removed. A bumper with the inventive structure as a layer, the structure layer free of resin in its interior to allow movement as desired, is an improvement over that currently used.

U.S. application No. 2007/0202314, PCT application WO 2007/067949 and U.S. application No. 2007/0194490 are examples where “crossless” structures are used as the substrate. Substitution of the present invention for at least some of these layers, the inventive layers not impregnated with resin to allow through thickness compression and spring back, results in an improved structure.

The present invention can also be used as shoe inserts or orthotic inserts, which are usually molded solid resin. Incorporation of a layer of the present invention improves the cushioning effect thereof. Soles/heels for sports shoes, which are usually solid viscoelastomeric materials, some attempts to improve “cushioning” have been to mold in for example “air channels or pockets.” However, the rigidity of the molded material is such that cushioning effects are limited. Incorporation of the present invention as a layer in the cast structure, free of “resin” to allow movement, substantially improves the cushioning effect of running/athletic shoes.

Therefore, it would be an advancement in the state of the “pad-making” art to provide a pad that provides excellent elastic behavior under load with high through thickness recovery.

SUMMARY OF THE INVENTION

The present invention is a ‘shock-absorbing pad’ that utilizes a unique structure which provides extremely elastic behavior under load with high through thickness recovery. The instant structure utilizes an elastic media in any direction, which allows the entire structure to ‘collapse’ into itself, based primarily upon the elasticity of this media and the structure to conform under pressure, thus allowing this unique behavior.

One embodiment of the invention is an ultra-resilient pad for use in a sports shoe, running shoes, regular shoes, boots etc. The structure may be a woven or nonwoven fabric including functional yarns in a longitudinal direction, layered both over as well as under the elastic media layered in a cross-direction. The elastic media used in the cross-direction may be polyurethane, rubber or Lycra or any deformable material that has sufficient elasticity as well as strength to allow the structure to compress and rebound, or ‘spring back.’ The entire structure can be ‘bound’ together utilizing a “binder pick,” or another yarn that is woven into the structure in order to bind the structure together to allow further processing of the said “base fabric.” Other means such as adhesives, welding technology or laser bonding can also be utilized for this bonding function.

The invention according to one embodiment is an ultra-resilient ‘carpet pad’ for use in floor carpets, sports floor, floor coverings etc. The structure may be a woven or nonwoven fabric including functional yarns in a longitudinal direction, layered both over as well as under the elastic media layered in a warp direction. The elastic media used in the warp direction may be polyurethane, rubber or Lycra or any deformable material that has sufficient elasticity as well as strength to allow the structure to compress and rebound, or ‘spring back.’ The entire structure can be ‘bound’ together utilizing a “binder pick,” or another yarn that is woven into the structure in order to bind the structure together to allow further processing of the said “base fabric.” Other means such as adhesives, welding technology or laser bonding can also be utilized for this function.

An object of the invention is to provide a structure that has improved recovery characteristics over memory foams, gels, spring systems, etc.

Another object of the invention is to form a smooth and uniform surface over the pad in order to improve support for the shoe and the foot.

Yet another object of the invention is to form a ‘planar,’ crossless structure of yarns with improved support of the carpet/sport floor/floor material.

Yet another object of the invention is to provide excellent retention of the recovery/dampening characteristics by utilizing the elastic material's ‘full’ recovery within the structure, as opposed to straight compression of materials. This is achieved due to the structure providing support between the sections of the elastic material, which avoids ‘overstressing’ the material, keeping it ‘alive’ and resulting in a longer useful lifetime.

Yet another object of the invention is to provide excellent resistance to moisture damage or problems due to water holding in certain applications due to the self-cleaning effect due to compression and subsequent recovery.

Yet another object of the invention is to provide an excellent compression recovery versus weight ratio, allowing significant dampening capability with light weight on structures.

Yet another object of the invention is to provide excellent ‘breathability’ of the shock absorbing structure, allowing perspiration and other moisture to evaporate and/or be removed during the compression phase.

For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying descriptive matter in which preferred, but non-limiting, embodiments of the invention are illustrated.

DETAILED DESCRIPTION OF THE INVENTION

The invention, according to one embodiment, is a ‘shock-absorbing’ pad that utilizes a unique structure which provides extremely elastic behavior under a normal pressure load with high caliper recovery. This structure 10 utilizes an elastic media in one direction of a woven or non-woven structure or fabric, which allows the entire structure to ‘collapse’ into itself, based upon the elasticity of this media and the base fabric structure to conform under pressure, and then recover to substantially the same original form and thickness, thus allowing a unique behavior.

One embodiment of the invention is shown in FIG. 1, which is a shoe pad 10 for use in shoes such as sports shoes, running shoes, regular shoes, boots etc. FIG. 2 illustrates the installation of the shoe pad 10 into foot wear, for example, a shoe. FIG. 3 is a ‘top view’ of the structure according to one example of the invention, also referred to as the base fabric, looking from above the fabric. FIG. 3 illustrates the use of functional yarns 20, 30 in one direction, for example a longitudinal direction of the fabric, layered both over as well as under the elastic media 40 in the cross-direction. Functional yarns can include any type of yarns (as in single monofilaments, multifilaments, texturized multifilaments, etc.) or combined structures (twisted, plied, knitted, braided of any number of materials or fabrics, composites, etc.), as known by ordinarily skilled artisans.

The elastic media 40 may be polyurethane, rubber or Lycra or any deformable material that has sufficient elasticity as well as strength to allow the structure to rebound, or ‘spring back.’ The structure 10 may be made in a 90 degree fashion, switching the longitudinal and cross direction yarns. It is to be noted that yarns/material/bands/cords 20, 30 are offset in the total structure 10 in order to allow the longitudinal sections to compress almost completely without interfering with one another in order to form a planar structure still with open area, so as to allow permeability. The entire structure 10 can be ‘bound’ together utilizing “binder picks” 50 as shown in FIG. 3, or another yarn that is woven into the structure in order to bind it together in order to allow further processing of the ‘base fabric.’ Other means such as for example adhesives, welding technology or laser bonding can also be utilized for this function of holding the structural yarns together.

The longitudinal yarns can be single in nature (as in single monofilaments, multifilaments, texturized multifilaments, etc.) or combined structures (twisted, plied, knitted, braided of any number of materials or fabrics, composites, etc.), as known by ordinarily skilled artisans. They can be permeable or impermeable to fluid. They can be comprised of polyesters, polyurethanes, polyamides, polyolefins, metals, rubber, Lycra etc. or combinations thereof.

A yarn that is defined as elastomeric in its length or axial direction is required for all the embodiments discussed. The yarn can also be elastomeric in its through thickness direction as well. The yarn can have any form as appropriate for the application and can be, for example, single monofilament, plied monofilament or a multifilament, wrapped yarns of different materials etc. It can be plied, twisted, knitted or braided. It can have any round or non-round cross sectional shape including square or rectangular as shown. Examples of good elastomeric materials are polyurethane, rubber or that sold under the trademark Lycra. The foregoing applied to all yarns referred to herein.

The fabric can be needled, if necessary, with fibers to produce a smooth surface, and can be coated with foams, coatings, or particulates. Other forms include a membrane, a yarn array, or another yarn fabric can be laminated to the fabric. The structure which includes these elastomeric yarns must be constructed to have sufficient degree of compressibility as well as have sufficient elasticity as well as strength to allow the structure to rebound, or ‘spring back.’ The compression and rebounding of the structure has the following benefits:

• • 1.) Improved recovery characteristics over memory foams, gels, spring systems, etc,
  • 2.) Smooth and uniform surface characteristics in, for example, items having ‘planar,’ crossless structure of yarns. (e.g.: to allow for improved support of the shoe and the foot).
  • 3.) Excellent retention of the recovery/dampening characteristics due to the elastic material's ‘full’ recovery within the structure (as opposed to straight compression of materials). This is due to the structure providing support between the sections of the elastic material; this avoids ‘overstressing’ the material, keeping it ‘alive’ (e.g., for a longer useful lifetime).
  • 4.) Excellent resistance to moisture damage or problems due to water holding due to self-cleaning effect of compression and recovery.
  • 5.) Excellent compression recovery vs. weight ratio, allowing significant dampening capability with light weight.
  • 6.) Excellent ‘breatheability’ of the shock absorbing structure, allowing perspiration and other moisture to evaporate and/or be removed at compression.

The structure 10 can be woven flat, endless, or compiled in another manner known to one of skill in the art. The indexing of the said longitudinal layers (or cross-direction layers if oriented in the other direction) can be critical, as the spacing of the structure must allow a uniform compression of the yarns into one another, thus allowing a uniform behavior over the entire length and width of the structure. It is to be noted that the structure can also be built without weaving, by subsequently laying said yarns perpendicular to one another as shown in FIGS. 4 and 5 and properly indexing in order to result in the finished structure. These yarns can be fixed in place via adhesives, welding techniques (laser and/or ultrasonic, for instance), or adhered with other welding and/or gluing techniques. Numerous layers can also be stacked in a perpendicular or angled fashion over each other to create a thicker, even more compressible structure.

The invention, according to one embodiment, is a ‘carpet pad’ that utilizes a unique structure 60 which provides extremely elastic behavior under load with high caliper recovery. This structure 60, for example shown in FIG. 7, utilizes an elastic media 140 in one direction of a woven fabric which allows the entire structure to ‘collapse’ into itself, based primarily upon the elasticity of this media 140 and the base fabric structure to confirm under pressure, thus allowing this unique behavior.

FIG. 7 is a ‘top view’ of the structure according to the invention, also referred to as the base fabric, looking from above the fabric. Yarns 120, 130 are used in one direction, for example a longitudinal direction of the fabric, layered both over as well as under the elastic media 140 in the cross-direction. The elastic media 140 may be polyurethane, rubber or Lycra or any deformable material that has sufficient elasticity as well as strength to allow the structure to rebound, or ‘spring back.’ The structure 60 may be made in a 90 degree fashion, switching the longitudinal and warp yarns. It is to be noted that yarns/bands/cords 120, 130 are offset in the total structure 60 in order to allow the longitudinal sections to compact totally without interfering with one another in order to form a planar structure still with open area, so as to allow permeability. The entire structure 60 can be ‘bound’ together utilizing “binder picks’ 150 as shown in FIG. 7, or another yarn that is woven into the structure in order to bind it together in order to allow further processing of the said ‘base fabric.’ Other means such as for example adhesives, welding technology or laser bonding can also be utilized for this function.

The longitudinal yarns can be single in nature (as in monofilaments, multifilaments, texturized multifilaments, etc.) or combined structures (twisted, plied, knitted, etc.). They can be permeable or impermeable to fluid. They can be comprised of polyesters, polyurethanes, polyamides, polyolefins, metals, rubber, Lycra etc. or combinations thereof. The fabric can be needled, if necessary, with fibers to produce a smooth surface of the fabric, and/or can be coated with foams, resin or latex coatings, or particulates. The structure that contains the elastomeric yarns must allow the structure to compress and rebound, or ‘spring back.’ The rebounding of the structure has the following benefits:

1.) Improved recovery characteristics over memory foams, gels, spring systems, etc.

2.) Smooth and uniform surface characteristics due to ‘planar,’ crossless structure of yarns (e.g., to provide improved support of the carpet/sport floor/floor material).

3.) Excellent retention of the recovery/dampening characteristics due to the elastic material's ‘full’ recovery within the structure (as opposed to straight compression of materials). This is due to the structure providing support between the sections of the elastic material; this avoids ‘overstressing’ the material, keeping it ‘alive.’ This provides, inter alia, a longer useful lifetime.

4.) Excellent resistance to moisture damage or problems due to the water holding due self-cleaning effect of compression.

The structure 60 can be woven flat, endless, or compiled in another manner known to one of skill in the art. The indexing of the said longitudinal layers (or cross-direction layers if woven in the other direction) may be critical, as the spacing of the structure must allow a uniform compression of the yarns into one another, thus allowing a uniform behavior over the entire length and width of the structure. It is to be noted that the structure can also be built without weaving, by subsequently laying said yarns perpendicular or angled to one another and properly indexing in order to result in the finished structure. These yarns can be fixed in place via adhesives, welding techniques (laser and/or ultrasonic, for instance), or adhered with other welding and/or gluing techniques. Numerous layers can also be stacked in a perpendicular fashion or angled over each other to create a thicker, even more compressible structure.

In yet another embodiment, the layers of a fabric may each be formed by mixing different weave repeats or shed patterns. By way of background, in float weaving, a warp yarn is threaded through a heddle, and the weave pattern is created by raising and lowering the heddle position for each yarn in the warp direction before the shute or pick is inserted into the shed created by raising or lowering the warp yarns. The number of yarns intersected before a weave pattern repeats is known as a shed, or harness. With this understanding, a plain weave utilizes, for example two sheds in a loom for changing the warp yarn positions, and can therefore be termed a two shed weave pattern. Accordingly a fabric can be comprised of a 2, 4, 6, 8 shed pattern and so on.

FIG. 8 shows 2-shed pattern with a 0.35 mm shute yarn; the figure showing two differing densities for the elastomeric yarn 40 and the binder yarn 50. For weaving a 2-shed surface for, for example, a 5-layer fabric with an elastomeric yarn 18, a 16 harness (16/4=4, 4/2=2 shed) pattern can be used. In another example, a 2-layer 4/8-shed weave can have a 4 ply Lycra® yarn as a shute.

Illustrating other embodiments of the structure, at FIG. 9 is shown the multi-component wound yarn comprising elastomeric material 40 for a multi-layer fabric having a 2 layer construction. At FIGS. 10A and 10B are shown embodiments of laminated structures of the fabric. FIG. 10A shows a base structure with the elastomeric yarn 40 and functional yarns 20, 30 laminated between two fabrics.

FIG. 10B shows a woven “crossless” base. The base shows the elastomeric yarn 40 and the functional yarns 20 and 30 as well as a binder yarn 50. Also contemplated are other embodiments where the elastomeric yarn can be a knitted yarn, or a hooked loop yarn.

For the embodiment including a hooked loop yarn, a fabric can be adapted to, for example, readily attach and replace fabric surfaces that are worn due to the stresses pads and structures undergo. In another example, a fabric can have surfaces that are exchangeable, thus allowing the same fabric to be put to different uses, such as a sports floor where different surfaces are desired for different sports.

In another embodiment, FIG. 11 shows a 5-layer compressible resilient fabric comprising a warp binder 50. The array 116 including the elastomeric yarn 40 running in the warp direction is positioned between the first array 112 and the third array 122. A fourth layer 126 including elastomeric yarns 40 has the yarns positioned such that they are in alternating spaces in the vertical plane from the parallel elastomeric yarns of the second layer 16. The yarns 20 of the fifth layer 128 are the same vertical plane the yarns 20 of the first layer 112. As shown in figures, each warp direction binder yarn 50 alternately weaves under and over three parallel yarns in the first and fifth layers, and is spaced in the shute direction such that long floats are created by each of the yarns 20 of the first layer 112 and the fifth layer 128. As shown, the elastomeric yarns are inside a double layer weave construction, which can use a 16 harness as for endless weaving or an 8 harness weave for flat weaving. The fabric woven in accord with the embodiment can use the single monofilament warp yarns or 4 ply yarns or other yarn types. It is also possible to use two different warp yarns, a coarser warp including the elastomeric yarn 40, and a shorter, smaller warp for the binder yarn 50. A fabric structure as shown in FIG. 11 was used with two separate warp beams. However, if two warps are not desired, the fabric/structure can also be configured to include a small binder yarn with elastomeric warp yarns and the crossover yarns woven over the elastomeric warp yarns.

FIG. 12 illustrates another embodiment including a weaving in of the warp yarns. As shown therein four ends of yarns 20 the first layer 112 weave above the layers 116, 122, 126 of elastomeric yarns 40, and changes over to a two-layer binder every second repeat, and four ends of yarns 20 weaving under the layers 116, 122, 126 and changes over to a two-layer binder every second repeat. Each layer need not be composed of elastomeric yarns. Rather, yarns may or may not be present depending on the degree of compressibility desired.

FIG. 13 shows yet another embodiment. FIGS. 13A, 13C and 13D show an uncompressed state, whereas 13B and 13E show a compressed state. In the figures, a single layer includes elastomeric yarns 40, here shown as elastomeric shutes 40, and functional yarns 60 in the same direction and alternating with the elastomeric yarns 40. The elastomeric yarn 40 is larger than the functional yarn 60. As shown, the elastomeric yarns 40 and functional yarns 60 can be in the shute direction; the fabric layer could also be adapted to include the larger elastomeric yarns 40 in a warp direction, as, for example, in a multiaxial fabric. As shown by, inter alia, the comparison at FIGS. 14D and 14E, the fabric is rendered compressible and resilient, even with a single layer construction. Also, by manipulating the shute and warp tensions, straighter warp yarns crossing the elastomeric yarns can be achieved.

Modifications to the present invention would be obvious to those of ordinary skill in the are in view of this disclosure, but would not bring the invention so modified beyond the scope of the appended claims.
