SLIP-RESISTANT HOSIERY
A slip-resistant hosiery is provided to reduce slipping of a foot within a shoe. In an example embodiment, a slip-resistant hosiery includes a body adapted to cover a foot of a wearer, a first gripping surface positioned at an outer surface section of the body, and a second gripping surface positioned at an interior surface section of the body. The first and second gripping surfaces are adapted to cover a posterior surface of a heel of the foot. The gripping surfaces may be at least semi-transparent. In another example embodiment, a slip-resistant hosiery includes a body adapted to cover a foot of a wearer, a first gripping surface positioned at an outer surface section of the body adapted to cover a surface above the plantar surface of the foot, and the first gripping surface is at least semi-transparent.
The following generally relates to hosiery.
DESCRIPTION OF THE RELATED ARTVarious types of hosieries, such as tights, pantyhose, leggings and socks are well known in the art. In general, hosieries serve as an intermediate layer between a wearer's foot and footwear to protect the skin of the wearer's foot from being rubbed directly against the footwear, since excessive rubbing of the foot may cause calluses and blisters to develop on the foot among other issues.
More specifically, a number of different types of hosieries are often produced using a material that has an easily slideable surface. For example, pantyhose are close-fitting legwear that are typically made of fabric such as nylon or other materials blended with nylon. Pantyhose are often worn for variety of purposes, such as to keep the feet and the legs warm, to keep the feet and the legs protected from the sun, or to appear fashionable. Although a variety of different footwear can be worn in conjunction with such hosiery, it is common for many women to wear high-heeled shoes and other fashionable footwear that generally provide minimal contact surface between the hosiery and the footwear.
Example embodiments of slip-resistant hosiery will now be described by way of example only with reference to the accompanying drawings in which:
It will be appreciated that for simplicity and clarity of illustration, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the example embodiments described herein. However, it will be understood by those of ordinary skill in the art that the example embodiments described herein may be practiced without these specific details. In other instances, well-known methods, procedures and components have not been described in detail so as not to obscure the example embodiments described herein. Also, the description is not to be considered as limiting the scope of the example embodiments described herein.
It has been observed that when hosiery made of a slippery material is worn, the wearer's feet will tend to unintentionally slip out of the footwear. This is more noticeable when only there is little contact surface area between the worn hosiery and the footwear, and only low friction is present between the footwear and the hosiery. Additionally, hosiery that easily slide against the inside of the footwear can cause uncomfortable rubbing sensation for the wearer with each step. Similarly, it has been recognized that hosiery that easily slide against the foot of the wearer can also cause similar problems.
As such, wearers can often encounter uncomfortable or hazardous situations when insufficient friction is present between the hosiery and the footwear being worn by the wearer, or between the hosiery and the skin of the foot of the wearer, or a combination thereof.
Although various solutions have been proposed for solving similar problems, known solutions for providing grip tend to be too bulky due to the thickness of the gripping surface, unfashionable due to the obvious presence of the gripping surface, or tend to cover undesirable portions of the wearer's feet, such as the entire sole of the wearer's feet, to make the wearer feel uncomfortable due to excessive grip and moisture being trapped by the presence of the gripping surface. Example embodiments of slip-resistant hosiery are described herein to address at least one of these issues.
A medial side view, a dorsal side view, and a bottom view of a typical foot of a person are illustrated in
The dorsal surface of forefoot 5 generally encompasses the top area of toes and the area surrounding the toes as shown in
The medial surface of the longitudinal arch 3 generally encompasses the inner side of the foot 1. The medial surface of the longitudinal arch may also be the area between the dorsal surface of the forefoot 5 and the posteromedial surface of the heel 2. Similarly, the lateral surface of the longitudinal arch 4 generally encompasses the outer side of the foot 1. The lateral surface of the longitudinal arch may also be the area between the dorsal surface of forefoot 5 and the posterior surface of heel 2.
The posterior surface of the heel 2 generally contains an area nearby or on the back of the foot 1. For example, the posterior surface of the heel 2 may only contain the rear most portion of the heel. In another embodiment, the posterior surface includes an area between the posteromedial to posterolateral surface of the heel, as shown in
The surface portions of the foot are shown in
A side view of an example embodiment of the slip-resistant hosiery is shown in
In general, the term “slip-resistant hosiery” herein refers to a body of hosiery that includes a gripping surface positioned at least on the outer surface section of the body.
The term “gripping surface” herein refers to a surface which provides improved friction for the hosiery. The hosiery may also additionally grip the skin of the person's foot. The gripping surface may, for example, be a polymeric material such as silicone. However, the gripping surface may be any type of polymer, resin, or any other types of material that provides improved friction against the interior of the footwear and the skin of the person's foot. The gripping surface, whether positioned at the outer surface or the inner surface of the hosiery, has a higher coefficient of friction compared to the coefficient of friction of the body of hosiery.
It will be appreciated that the relative or absolute values of the coefficient of friction of the gripping surface and the coefficient of friction of the body of the hosiery may vary, taking into account that the coefficient of friction of the gripping surface is greater than the coefficient of friction than the body of the hosiery. The following is a list of non-limiting example embodiments describing the values of the coefficient of friction. In an example embodiment, the coefficient of friction of the gripping surface is at least 10% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 20% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 30% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 40% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 50% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 60% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 70% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 80% greater than the coefficient of friction of the body of the hosiery In an example embodiment, the coefficient of friction of the gripping surface is at least 90% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the coefficient of friction of the gripping surface is at least 100% greater than the coefficient of friction of the body of the hosiery. In an example embodiment, the gripping surface has a coefficient of friction greater than 0.5.
The gripping surface may be secured to the hosiery in a number of different ways, depending on the type of hosiery used and the choice of material for providing the gripping surface. For example, the gripping surface is directly or indirectly sprayed on, molded on, or embedded within the body of the hosiery. In another embodiment, the gripping surface is weaved into the fabric of the hosiery. In another example embodiment, the gripping surface is pre-formed and then secured to the hosiery using glue or any other methods.
In an example embodiment, the gripping surface is at least semi-transparent. In another example embodiment, the gripping surface is transparent. A semi-transparent or transparent gripping surface is desirable because it is not easily visible to people. This would make the slip-resistant hosiery more fashionably appealing while still providing a gripping surface. In another example embodiment, the gripping surface is opaque. In another example embodiment, the gripping surface has a color tint matching a color of the skin or a color of the hosiery, such that the presence of the gripping surface is not easily detected by eye. In example embodiments where there is an outer gripping surface and an inner gripping surface, the outer gripping surface may have a color tint matching the color of the body of the hosiery, or both the inner and the outer gripping surfaces have the color tint. The use of color for the gripping surface applies to semi-transparent and opaque materials. This enables a person to wear the hosiery with footwear having different designs and configurations without having to worry about the gripping surface being exposed in an unsightly manner.
In another example embodiment, the gripping surface comprises a material that stretches easily, such as an elastomer, for example, such that the gripping surface stretches to conform to the profile of the wearer's feet to provide additional comfort. The use of elastomer also enables the same hosiery to be worn by wearers with different sizes of feet.
In a preferred example embodiment, the gripping surface has a low profile, or, in other words, is thin. In some example embodiments, the gripping surface is embedded within the hosiery. In these ways, a person wearing the slip-resistant hosiery will not be able to easily feel any raised bumps or surfaces. The person wearing the slip-resistant hosiery will feel as if he or she is wearing a typical hosiery garment, however, with the advantage of reduced slipping against the interior of the shoe and the person's foot. It is recognized, for example, that high-profile or thick material added to hosiery would reduce the amount of room in a wearer's shoe, and may undesirably change the feel or fitting of the shoe when wearing hosiery with thick material.
Continuing with the example embodiment of the slip-resistant hosiery 10 shown in
The inner and outer gripping surfaces are shown in
In
The example embodiment of the slip-resistant hosiery shown in
The combination of the inner gripping surface and the outer gripping surface generally reduces the slippage of both hosiery and the shoe experienced by the wearer.
In
The gripping surface 11 of the slip-resistant hosiery 10 may further include an outer gripping surface 11e and an inner gripping surface 11f as shown in
For open-toed shoes, it can be desirable to have the gripping surface located only at the rear portion of the hosiery, so that the gripping surface is not visible at the open-toe portion of the shoe.
Turning to
In the side view of the embodiment as shown in
As shown more clearly in
The example embodiment shown in
In another example embodiment of the invention (not shown in the figures), the hosiery includes a front gripping surface placed on the portion of the hosiery for encompassing the dorsal surface of the forefoot, a medial side gripping surface placed on the portion of the hosiery for encompassing the medial surface of the longitudinal arch, a lateral side gripping surface placed on the portion of the hosiery for encompassing the lateral surface of the longitudinal arch and a rear gripping surface placed on the portion of the hosiery for encompassing the posterior surface of the heel without any of the gripping surfaces overlapping. Furthermore, each of the gripping surfaces may include an outer gripping surface and an inner gripping surface as previously described.
In another example embodiment of a slip-resistant hosiery, the hosiery includes a gripping surface positioned to cover a surface of above the plantar surface of the foot. The gripping surface may be placed, for example, to cover at least one of the dorsal surface of the forefoot, the medial surface of the longitudinal arch, the posterior surface of the heel or the lateral surface of the longitudinal arch. However, the plantar surface of the foot may not be covered by the gripping surface in the example embodiment. Furthermore, the gripping surface may include an outer gripping surface or a combination of an outer gripping surface and an inner gripping surface as previously described.
There are a number of advantages to forming a continuous gripping surface. The continuous gripping surface 31 provides a larger gripping surface area around the front, heel, and sides of the foot, thereby further reducing slippage of a wearer's foot within a shoe. Additionally, the continuous gripping surface 31 reduces the likelihood of the gripping surface peeling off the hosiery because there are less edges of the gripping surface being exposed in the continuous form. Additionally, a large portion of the dorsal surface of the foot and the entire plantar surface of the foot is not covered by the gripping surface. Thereby, breathability of the foot is maintained. Further, when the wearer takes off their shoes and walks in the hosiery, it will feel to the wearer as if they are wearing typical hosiery. Similarly with previous embodiments, the continuous gripping surface may further include an inner gripping surface adapted to grip the skin of the wearer's foot and an outer gripping surface adapted to grip the inner surface of the shoe. The combination of the inner gripping surface and the outer gripping surface further reduces the slippage of the wearer's foot within a shoe.
It is preferable to maintain at least a portion of the plantar surface uncovered from the gripping surface, for example, to maintain breathability and comfort. As best seen in
It will be appreciated that positioning of the gripping surface, whether on the outer surface or the inner surface of the body of the hosiery, or both, can vary. It will also be appreciated that there are many different combinations of the above mentioned surfaces of the foot that can be covered by the gripping surface, and all of these combinations are applicable to slip-resistant hosiery even if these combinations have not been explicitly described herein.
