BACKGROUND

Field of the Invention

This invention relates to leg coverings; and more particularly to a leg covering comprising a plurality of folds.

Description of the Related Art

Leg coverings such as sleeves and socks are commonly worn in a variety of sports including football. Such leg coverings can protect the user from burns and scratches resulting from playing on rough surfaces like artificial turf. Generally, a preferred leg covering has a sufficient amount of tightness while not over constricting blood flow.
More recently, a pattern of wearing a sleeve or sock with a plurality of folds has gained popularity. The plurality of folds can prevent over constriction while also providing breathability to the leg. An aesthetic look of the leg covering with a plurality of folds can be also be highly desirable. Current ways of achieving a leg covering with a plurality of folds is to use a conventional leg covering with an extra-long length and to manually adjust the leg covering until there is a relatively even distribution of folds. This process can be time consuming and the plurality of folds can flatten over time. There is a need for an improved leg covering.

SUMMARY

A leg covering is disclosed, the leg covering comprises a tubular body having a proximal end and a distal end opposite the proximal end. At an inner surface of the tubular body comprises a plurality of elastic bands coupled thereto. Each of the plurality of elastic bands is coupled to both an upper half of the tubular body and a lower half of the tubular body. Each of the plurality of elastic bands comprises an unstretched length. A portion of the tubular body coupled to each of the plurality of elastic bands comprises a static length, wherein the static length is greater than the unstretched length of each of the plurality of elastic bands. The plurality of elastic bands causes a plurality of folds to from along an outer surface of the tubular body.
In some embodiments, the leg covering may be a sleeve. In other embodiments, the leg covering may be a sock.

In one exemplary aspect, a method includes folding a tubular inside out such that an inner surface of the tubular body is externally exposed; placing the tubular body onto an elongated extension of a sewing machines, the elongated extension configured to nest within the tubular body; aligning one of a proximal end or a distal end of the tubular body under a presser foot of the sewing machine; placing one end of a first elastic band under the presser foot; stretching both the first elastic band and the tubular body; stitching the first elastic band to the tubular body by sliding both the tubular body and first elastic band along the elongated extension; removing the tubular body and the first elastic band from the elongated extension; rotating the tubular body to a side opposite where the first elastic band is attached; inserting the tubular body onto the elongated extension and under the presser foot; placing one end of a second elastic band under the presser foot; stretching both the second elastic band and the tubular body; and stitching the second elastic band to the tubular body by sliding both the tubular body and the second elastic band along the elongated extension;
As disclosed herein, the first and second unstretched lengths are less than the static length of the contracted portion. In an exemplary embodiment, a ratio of the static length to the first unstretched length is around 1.6. In preferable embodiments, the ratio may comprise a range between and include of 1.2-2.0. Too low of a ratio causes the tubular body to be under compressed thereby creating an insufficient number of folds. Too high of a ratio causes the first elastic band (and subsequently the second elastic band) to become overstretched which can cause too many and too tight of folds and can also interfere with the leg covering adequately covering the user's leg.

First Illustrated Embodiment

Now turning to the drawings, FIG. 1 shows a front view of a leg covering (100) in accordance with a first illustrated embodiment. The leg covering comprises a sleeve (101) having a proximal end (111), a distal end (112) opposite the proximal end, and a tubular body (110) extending therebetween. The proximal end and the distal end comprise a proximal opening (113) and distal opening (114), respectively, to allow the sleeve to slide onto a user's leg. The tubular body has an outer surface (116) and an inner surface (not shown) opposite the outer surface. The tubular body further comprises an upper half (117) disposed adjacent to the proximal end, and a lower half (118) disposed adjacent to the distal end. Coupled at the inner surface of the tubular body is a first elastic band (120) and a second elastic band (130). The first and second elastic bands are disposed on opposite sides of the tubular body. A portion of the tubular body coupled to each of the first and second elastic bands is defined as a contracted portion (140). The first and second elastic bands contract the contracted portion, thereby forming a plurality of folds (160) along the outer surface.
The first elastic band (120) comprises a first unstretched length (122). The second elastic band (130) comprises a second unstretched length (132). In some embodiments, the first and second unstretched lengths are equal. In other embodiments, the first and second unstretched lengths differ. Each of the first and second elastic bands are coupled to the inner surface (not shown) of the tubular body (110) by a series of stitching running along the tubular body. The contracted portion (140) comprises a static length. The static length is defined as a length of the contracted portion while the contracted portion is undergoing no contraction or compression from the first and second elastic bands. The plurality of folds (160) is formed when the static length is greater than both the first unstretched length and the second unstretched length. In such a configuration, the first and second elastic bands must be stretched prior to coupling to the inner surface of the tubular body. Subsequently, the first and second elastic bands retract back to the first and second unstretched lengths which causes the plurality of folds to form.
In some embodiments, the first and second elastic bands (120; 130) extend completely across the tubular body (110) from the proximal end (111) to the distal end (112). In other embodiments, the first and second elastic bands extend across a portion of the tubular body. The sleeve (101) may comprise a proximal cuff (150) disposed at the proximal end. Additionally, the sleeve may comprise a distal cuff (151) disposed at the distal end.
Generally, the first elastic band (120) is coupled to both the upper half (117) and the lower half (118) of the tubular body (110). Furthermore, the second elastic band (130) is generally coupled to both the upper half and lower half of the tubular body.
As shown, the leg covering (100) preferably comprises two elastic bands, namely the first elastic band (120) and the second elastic band (130). In other embodiments, the leg covering may comprise a plurality of elastic bands greater than two. In each configuration of plurality of elastic bands (for example two elastic bands, three elastic bands, four elastic bands, etc.), the plurality of elastic bands can be disposed at the inner side of the tubular body (110) in such a manner than can be characterized as radially even. For example, a configuration of two elastic bands, as illustrated, may be spaced radially even on the tubular body such that each of the two elastic bands is spaced 180 degrees from one another. This can also be characterized as being disposed on opposite sides of the tubular body. A configuration of three elastic bands may be spaced radially even on the tubular body such that each of the three elastic bands is spaced 120 degrees from one another. A configuration of four elastic bands may be spaced radially even on the tubular body such that each of the four elastic bands is spaced 90 degrees from one another. One having skill in the art will appreciate that configuring the plurality of elastic bands radially even allows for a distributed contraction around a user's leg while the leg covering is being worn.
FIG. 2 shows a side view of an inner surface (115) of the leg covering (100) according to the first illustrated embodiment. The leg covering comprises tubular body (110) having a proximal end (111) and a distal end (112) opposite the proximal end. A first elastic band (120) is coupled to the tubular body at the inner surface. A second elastic band (not shown) is coupled at the inner surface of the tubular body opposite the first elastic band. The first and second elastic bands retract a portion of the tubular body coupled therewith which causes a plurality of folds (160) to form. In a preferable embodiment, the first and second elastic bands are each coupled to both an upper half (117) and a lower half (118) of the tubular body. The leg covering comprises a proximal opening (113) and a distal opening (114) to allow the leg covering to slide onto the user's leg. In some embodiments, the upper half and lower half are symmetrical such that the proximal end and the distal end are indistinguishable and interchangeable.
In some embodiments, each portion of the first elastic band (120) is coupled to the tubular body (110). In other embodiments, the coupling of the first elastic band comprises a plurality of gaps wherein the first elastic band is coupled to the inner surface (115) of the tubular body by a plurality of contact points. In some embodiments, the second elastic band is symmetrical to the first elastic band in form and function. The coupling of the first and second elastic bands can be achieved by a plurality of means as can be appreciated by one having skill in the art. In a preferable embodiment, the first and second elastic bands are stitched to the inner surface, thereby creating a first stitching and a second stitching at an outer surface of the tubular body.
FIG. 3 shows a top inner view of the leg covering (100) according to the first illustrated embodiment. The leg covering shows an inner surface (115) of a tubular body (110). Coupled to opposite ends of the tubular body at the inner surface is a first elastic band (120) and a second elastic band (130), respectively. A proximal end (111) of the tubular body having a proximal opening (113) is shown to allow a user to fit their foot through said proximal opening and slide the tubular body onto their leg.
FIG. 4 shows a perspective view of the leg covering (100) being worn according to the first illustrated embodiment. The leg covering is a sleeve (101) that can be worn in various ways. As illustrated, a proximal end (111) is disposed below a user's knee and a distal end (112) is disposed above the user's ankle. A tubular body (110) extends from the proximal end to the distal end and covers a substantial portion of the user's lower leg. A plurality of folds (160) is formed by a contracted portion (140) of the tubular body. The contracted portion is created by a first elastic band (120) extending along the tubular body from an upper half (117) of the tubular body to a lower half (118). A second elastic band (not shown) extends along the tubular body from the upper half of the tubular body to the lower half. As shown, the first elastic band is coupled to the tubular body at an inner surface (not shown) which contacts the user's leg. The first elastic band is stitched by a first stitching (122).
While various details, features, and combinations are described in the illustrated embodiments, one having skill in the art will appreciate a myriad of possible alternative combinations and arrangements of the features disclosed herein. As such, the descriptions are intended to be enabling only, and non-limiting. Instead, the spirit and scope of the invention is set forth in the appended claims.

Second Illustrated Embodiment

The leg portion comprises a tubular body (210) having a proximal end (211) and a distal end (212) opposite the proximal end. The proximal end comprises a proximal opening (213). The distal end is coupled to the sock foot portion. The tubular body has an outer surface (216) and an inner surface (not shown) opposite the outer surface. The tubular body further comprises an upper half (217) disposed adjacent to the proximal end, and a lower half (218) disposed adjacent to the distal end. Coupled at the inner surface of the tubular body is a first elastic band (220) and a second elastic band (230). The first and second elastic bands are disposed on opposite sides of the tubular body. A portion of the tubular body coupled to each of the first and second elastic bands is defined as a contracted portion (240). The first and second elastic bands contract the contracted portion, thereby forming a plurality of folds (260) along the outer surface.
The first elastic band (220) comprises a first unstretched length (222). The second elastic band (230) comprises a second unstretched length (232). In some embodiments, the first and second unstretched lengths are equal. In other embodiments, the first and second unstretched lengths differ. Each of the first and second elastic bands are coupled to the inner surface of the tubular body (210) by a series of stitching running along the tubular body. The contracted portion (240) comprises a static length. The static length is defined as a length of the contracted portion while the contracted portion is undergoing no contraction or compression from the first and second elastic bands. The plurality of folds (260) is formed when the static length is greater than both the first unstretched length and the second unstretched length. In such a configuration, the first and second elastic bands must be stretched prior to coupling to the inner surface of the tubular body. Subsequently, the first and second elastic bands retract back to the first and second unstretched lengths which causes the plurality of folds to form.
In some embodiments, the first and second elastic bands (220; 230) extend completely across the tubular body (210) from the proximal end (211) to the distal end (212). In other embodiments, the first and second elastic bands extend across a portion of the tubular body. The leg portion may comprise a proximal cuff (250) disposed at the proximal end.
Generally, the first elastic band (220) is coupled to both the upper half (217) and lower half (218) of the tubular body. Furthermore, the second elastic band (230) is generally coupled to both the upper half and lower half of the tubular body.
As shown, the leg covering (200) preferably comprises two elastic bands, namely the first elastic band (220) and the second elastic band (230). In other embodiments, the leg covering may comprise a plurality of elastic bands greater than two. In each configuration of plurality of elastic bands (for example two elastic bands, three elastic bands, four elastic bands, etc.), the plurality of elastic bands can be disposed at the inner side of the tubular body (210) in such a manner than can be characterized as radially even. For example, a configuration of two elastic bands, as illustrated, may be spaced radially even on the tubular body such that each of the two elastic bands is spaced 180 degrees from one another. This can be also interpreted as being disposed on opposite sides of the tubular body. A configuration of three elastic bands may be spaced radially even on the tubular body such that each of the three elastic bands is spaced 120 degrees from one another. A configuration of four elastic bands may be spaced radially even on the tubular body such that each of the four elastic bands is spaced 90 degrees from one another. One having skill in the art will appreciate that configuring the plurality of elastic bands radially even allow for a distributed contraction around a user's leg while wearing the leg covering.
