BACKGROUND SummaryIn one exemplary embodiment, a sock includes a cuff portion, an upper portion, and a lower portion. The lower portion includes at least one non-compressive resistant fiber, a heal area, a toe area, and at least one compressive resistant fiber. The at least one compressive resistant fiber is located in at least one of the heal area and the toe area and.
These and other features of the disclosed examples can be understood from the following description and the accompanying drawings, which can be briefly described as follows.
This disclosure generally relates to compressive resistant fabrics used in clothing, such as socks, or in other applications where a compressive resistant fabric is needed. As discussed further below, compressive resistant fabric possesses many benefits when incorporated into apparel, such as socks in one example.
The toe portion 12 is located at a distal end of the sock 10 opposite the cuff portion 20 and is enclosed to form an end of the sock 10. In the illustrated embodiment, the toe portion 12 includes a toe seem 12A that encloses the distal end of the sock 10.
The upper portion 14 is located on a top side of the sock 10 such that the upper portion 14 would be located adjacent a top side of a foot located in the sock 10.
The lower portion 16 is located on a bottom side of the sock 10 opposite the upper portion 14. The lower portion 16 is configured to be located adjacent a bottom side of a foot located in the sock 10.
The heel portion 18 forms a transition between the cuff portion 20 and the lower portion 16 of the sock 10. The heel portion 18 is configured to be located adjacent a heel of a foot located in the sock 10. In the illustrated embodiment, the heel portion 18 includes a heel seam 18A that connects adjacent pieces of the heel portion 18 such that the heel portion 18 will conform to a general heel shape of a foot in the sock 10.
The cuff portion 20 is located at a proximal end of the sock 10 and includes an opening 22 that provides access to an interior of the sock 10 such that the sock 10 can accept a foot inside. The cuff portion 20 contributes to maintaining the sock 10 on a foot by incorporating an elastic or stretchable material into the fabric that will reduce a width dimension of the cuff portion 20 such that the cuff portion 20 will fit snuggly against the ankle but not slide down past the ankle and foot.
In the illustrated non-limiting embodiment, the toe and heel serpentine patterns 26A, 26B follow a generally widthwise path in the lower portion 16. In another embodiment, the toe and heel serpentine patterns 26A, 26B follow a generally longitudinal pattern back and forth towards the heel portion 18 and the toe portion 12. Although the toe and heel serpentine patterns 26A, 26B are shown as a single fiber or thread with a connecting portion 24B of the compressive resistant fiber 24 extending through an arch portion 28, the toe and heel serpentine patterns 26A, 26b could be formed from separate compressive resistant fibers 24.
In another non-limiting embodiment, a density or concentration of the compressive resistant fibers 24 could be different between the toe serpentine pattern 26A and the heel serpentine pattern 26B. Moreover, in yet another embodiment, the sock 10 could include either the toe serpentine pattern 26A or the heel serpentine pattern 26B but not both.
Moreover, using the compressive resistant fibers 24 instead of a solid compressive resistant pad reduces the weight of the sock 10 by allowing the compressive resistant fibers 24 to expand and fill the dead or void spaces in the fabric of the sock 10. Using the compressive resistant fibers 24 in place of a solid compressive resistant pad also increases the breathability of the sock 10.
The compressive resistant fibers 24 in the sock 10 may vary depending on the application of the sock 10, such as an athletic sock compared to a casual or dress sock. The compressive resistant fibers 24 can include encapsulated gels, rubbers (synthetic and natural), silicones, fluoroelastomer, fluoropolymer, foams, and other suitable materials. These materials are easily cleaned and resistant to deterioration under significant compressive forces.
A durometer of the compressive resistant fibers 24 can range from 10-80 on the Shore-A scale. In one non-limiting embodiment, the compressive resistant fibers 24 are silicone and include a Shore-A rating of 20 or 30 and a diameter of 1/64th of an inch or 1/32nd of an inch, respectively. For example, athletic socks could include a greater durometer and thread diameter to withstand greater loads place on the sock 10 during use while a dress sock, casual sock, or pantyhose could include a lower durometer and thread diameter to accommodate lower load levels and fitting within a person's normal size dress shoe.
The cross-sectional profile of the compressive resistant fibers 24 could also include varying cross sections such circumferential or longitudinal grooves, protrusions, or textures. These features in the compressive resistant fibers 24 can promote stimulation or provide feedback through a person's foot through the foot coming into contact with the varying cross sections.
Moreover, the compressive resistant fibers 24 used in the heel serpentine pattern 26B could include different physical properties from the compressive resistant fibers 24 in the toe serpentine pattern 26A. This will allow the sock 10 to accommodate different applications such where the amount of compressive force applied by a heel or ball region of the foot varies.
The compressive resistant fibers 24 may also include properties that vary depending on temperature, such as body warmth, and duration of compressive force applied. These properties could be achieved through the use of thermoplastics or anti-Newtonian materials.
As shown in
Alternatively, the compressive resistant fibers 24 could extend widthwise and the non-compressive resistant fibers 30 could extending longitudinally. The configuration of the compressive resistant fibers 24 in
Although the illustrated embodiment shows the entire lower portion 216 of the sock 210 having compressive resistant fibers 24, only a portion of the lower portion 216 could include compressive resistant fibers such as shown and described in relation to the compressive resistant fibers 24 in the sock 10 in
Although the above disclosure is in relation to socks, this disclosure also applies to underwear, padding for pant knees, padding in elbows of shirts, padding in exercise garments, the palm of gloves, helmets, bed sheets, upholstery fabrics, and motor vehicle fabrics among others.
The preceding description is exemplary rather than limiting in nature. Variations and modifications to the disclosed examples may become apparent to those skilled in the art that do not necessarily depart from the essence of this disclosure. The scope of legal protection given to this disclosure can only be determined by studying the following claims.
