Description

THERMOFORMABLE FABRIC SHOE SOLE AND UPPER
This application is based on U.S. provisional application serial no. 60/076,187, filed February 27, 1998.
BACKGROUND OF THE INVENTION Field of the Invention
The present invention is directed to footwear having a thermoformable fabric midsole and upper.
Discussion of the Background
It is known to provide a midsole for footwear with elastically deformable members to provide energy conservation associated with athletic activities such as running and jumping. For example, U.S. Patent 5,092,060, the subject matter of which is hereby expressly incorporated by reference, teaches a shoe comprising a sole with elastically deformable elements provided therein. The elastically deformable elements provide energy conservation of the users' movements and thereby enhance the users' performance. However, the elastically deformable elements taught by U.S. Patent 5,092,060 can be costly to manufacture and therefore it has been found desirable to provide elastically deformable elements which are more easily and inexpensively manufactured.
The construction of uppers for footwear typically is in form in the form of a relatively heavy material to provide adequate protection of the wearer and is often not lined. Thus, such does not provide a proper ventilation or provide for comfort of the upper portion of the foot of the wearer by softening the impact of the foot with the upper when worn by the wearer. It has therefore been recognized that a need exists for providing a lightweight upper or a liner for an upper which provides greater air flow and greater comfort when worn.
U.S. Patent 4,458,429 discloses a padded tongue for footwear comprising a front layer having multiple orifices passing therethrough, each orifice having a porous or reticular material therein wherein the tongue is assembled by adhering the front layer to the back layer along the circumference of the tongue and each of the orifices through to the meshes of an intermediate layer by heat-welding. It is also known from U.S. Patent 4,592,943 to utilize an apparatus and method of forming an open mesh belt on the fabric by heat or fusion bonding a web comprising conjugate fibers. The foregoing patents, the disclosure of which is also incorporated herein by reference, fail to teach, however, the provision of a thermoformable fabric for the upper or the lining of an upper of a shoe so as to provide the benefits of comfort and air flow as explained above.
Conventionally, foam has been used to line shoe uppers. However, it has been found that foam is heavier, requires the use of cement, and is less breathable than thermoformable fabrics. For example, when a foam is laminated to the inside face of the upper fabric of footwear and a further inner lining material such as a nylon tricot is applied, a three layered structure results. Such soft layers are typically held in firm alignment by the use of cement provided between each layer. Such construction results in an upper that has a high degree of stiffness due to the layers of cement.
SUMMARY OF THE INVENTION
In view of the above-noted drawbacks of the prior art, it has been recognized that it would be advantageous to improve upon the state of the prior art. It is therefore an object of the present invention to accomplish this by the use of a woven or knitted material that is shaped by application of a heating pressure and a forming mold, for construction of various components of footwear. According to one aspect of the present invention, a flexible, dimpled thermoformable fabric is used as an upper lining sheet. This lining sheet provides slight cushioning of a foam-lined upper but with less weight and greater breathability.
According to a further aspect of the present invention, a stiff thermoformable fabric is provided as a rigid element for use as the midsole or as part of the midsole of footwear. The shape of the rigid elements serve to provide cushioning by mechanical distortion when a load is applied to the midsole.
It is a further object of the present invention to provide an upper or lining for an upper as described above in combination with a midsole having stiff thermoformable fabric positioned thereon or located therein in accordance with the present invention.
-2- BRIEF DESCRIPTION OF THE DRAWINGS
A more complete appreciation of the invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description.
Figure 1 is a right side perspective view of a first embodiment of the shoe showing a dimpled upper lining in accordance with the present invention;
Figure 2 is a top plan view thereof;
Figure 3 is a right side elevational view thereof;
Figure 4 is a rear elevational view thereof;
Figure 5 is a perspective of a flexible dimpled thermoformable fabric utilized in the embodiment shown in Figure 1 ; and
Figure 6 is a perspective view of a stiff thermoformable fabric with corrugations in the shape of truncated cones that is utilized in the second embodiment of the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Figures 1 through 4 illustrate an embodiment of the present invention where footwear 1 is illustrated with a lining for an upper 2 which is made of the flexible thermoformable fabric 4 shown in Figure 5, .and covered with a mesh shell. By manufacturing a shoe upper with such fabric, greater flexibility in manufacturing is achieved than that resulting from a conventionally made upper. For example, a lining made from a sheet of flexible thermoformable material has a mechanical spring resiliency similar to that provided by a layer of foam. However, the sheet is allowed to float freely within some or all of the upper.
Preferably, the lining is spot welded, glued, riveted or stitched to reduce relative movement between multiple layers forming a shoe upper. The corrugations formed in the flexible fabric also provide cushioning for the user's foot, and provide increased ventilation between the user's foot and the upper.
The fabric may be a polyester, polymer, polyurethane, nylon or other plastic fiber. The fibers of the fabric may be of any thickness that provides sufficient stiffness and abrasion resistance in the desired use. For example, a 1000 dernier fiber might be stiff and abrasion resistant enough for outdoor hiking boot applications while a lighter weight, such as 220 denier fibers, might be used in women's casual footwear. The overall height of the
-3- corrugations formed in the flexible thermoformable fabric, i.e. the distance between the upper and lower faces of the material, must exceed twice the thickness of the textile sheet before it is provided with corrugations. Preferably, the upper to lower face distance in the corrugated flexible thermoformable material is in excess of 5 times the thickness of the textile sheet from which it is formed. The preferred thickness of the material depends on the intended use and the desired stiffness of the final product.
The method for manufacturing such a fabric as shown in Figure 5, is generally known, and includes heating the fabric to approximately 300 degrees Fahrenheit, depending on the material used, then pressing the material between a male and female die.
According to the second aspect of the invention, as discussed above, a stiff thermoformable fabric 6 is included in the midsole 10 of the footwear although it would be possible to also place this in an outsole. Thus the term sole is intended to include midsoles or outsoles. Figure 6 shows an example of a stiff thermoformable fabric 6 with truncated cone corrugations 8, which can be suspended in a midsole of the footwar, thereby creating a sole with spring-like flexibility. Preferably, the truncated cones are arranged according to the biomechanics of a user's foot, and are suspended in the material comprising the midsole 10 of the footwear. Typically, the midsole is made from a foam type material. The truncated cones, when suspended in the foam, provide the energy conservation sought.
The fabric used for the stiff thermoformable fabric in Figure 6 is generally thicker than that used in the fabric in Figure 5. The fabric used for stiffening the midsole of the footwear may be of any thickness that provides a suitable stiffness for the intended use. For example, a carbon fiber and resin composite material may be only 0.5 mm thick and still be stiff enough to provide the desired midsole support. Preferably, a midsole of footwear provided with a thermoformable fabric in accordance with the invention, should decelerate a missile striking the top surface of the midsole with a peak g force not greater than 28g. It is preferred that the material provides a peak g force of 12 to 18g in a traditional footwear missile impact test. It has been found that the maximum desirable thickness is approximately 3mm, while the average thickness is from 0.5 to 1.5mm for the materials used in the present invention.
It is conceived that a plurality of the truncated cones 8 shown in Figure 6 will be dispersed throughout the sole of a shoe, wherein the cones will have varying sizes and arrangements according to the biomechanics of the foot and the intended activity for which the footwear is used.
The foregoing illustrate only preferred embodiments of the invention. However, variations onto and modifications of the foregoing are possible as would be understood by one of ordinary skill in the art.
