Definitions

  • the present invention relates to elastic cords and apparatuses and methods for securing two or more objects, or portions thereof, in proximity with one another.
  • Prior shoelaces have been made of absorbent materials such as cotton and other hydrophilic materials. A problem with these materials is that they attract liquid from the environment and perspiration from the user's body instead of wicking the moisture away.
  • an elastic rubber core is surrounded by an absorbent outer cover. When the outer cover absorbs fluids and sweat, especially during athletic activity, the rubber core may become brittle and loose its elastic properties. Additionally, when prior art elastic shoelaces are washed and dried, heat can cause the rubber inner core to deteriorate.
  • Articles which each employ a lacing system to releasably secure two or more portions of the article in proximity with one another have long required that the user tie together the free end portions of a lace which has been threaded through a plurality of eyelets in respective portions of the article.
  • the lace typically is first threaded through eyelets in respective halves of an upper portion of the footwear, and the halves are synched together by pulling upon the free end portions of the threaded lace. Once the halves have been synched together as desired the user ties together the free end portions of the lace to prevent the upper portion halves from spreading apart, thereby securing the footwear to the foot.
  • an elastic cord comprises a first end, an opposite second end, an outer cover formed from an air permeable, hydrophobic wicking fiber material, and an elastic core.
  • the outer cover is formed from a polymer weave.
  • the core is formed from an elastic polymer.
  • the elastic polymer is formed from Lycra ® .
  • the elastic core is formed from a plurality of grouped strands.
  • the elastic cord is between 18 - 30 inches long. In other of these embodiments, the elastic cord is more than 30 inches in length.
  • a locking mechanism is adapted to releasably receive the elastic cord so that a portion of the elastic cord forms a loop between the first end and the second end of the elastic cord, the locking mechanism being adapted to allow for the adjustment of the length of the loop.
  • the locking mechanism further comprises a body and a wheel, wherein the wheel is slidably received by the body so as to releasably secure the elastic cord within the body.
  • an elastic cord comprises an elongated string having first end and an opposite second end, an outer cover formed from recycled polymer material, and an elastic core.
  • the outer cover is formed from an air permeable, hydrophobic wicking fiber weave.
  • the elastic core is an elastic polymer.
  • the elastic core is formed from Lycra ® .
  • the elastic core is formed from a recycled polymer.
  • an article of footwear comprises a sole, an upper portion connected to said sole and defining a plurality of eyelets, an elastic cord comprising a first end, a second end, an outer cover formed from an air permeable, hydrophobic wicking fiber material, and an elastic polymer core wherein the elastic cord has a length sufficient to be threaded through the plurality of eyelets, and a flange located at a first side of the plurality of eyelets proximate a toe portion of the upper portion, the flange defining a recessed portion, wherein when the elastic cord is secured, at least one loop is formed adjacent a second side of the plurality of eyelets distal from the toe portion, and the at least one loop is received by the flange recessed portion.
  • the outer cover is formed from a recycled polymer. In still other embodiments, the outer cover is formed from a polymer weave. In yet other embodiments, the outer cover is formed from recycled plastic bottles. In other embodiments, the core is formed from Lycra ® . In still other embodiments, the elastic polymer core is formed from a plurality of grouped strands.
  • FIG. 1 is a partial plan view of a shoelace in accordance with one embodiment of the present invention.
  • FIG. 2A is a cross-section view of the shoelace shown in FIG. 1 ;
  • FIG. 2B is a cross-section view of the shoelace shown in FIG. 1 shown in a stretched orientation;
  • FIG. 3 is a partial plan view of the shoelace shown in FIG. 1 ;
  • FIG. 4 is a perspective top view of a shoe which incorporates a preferred lacing apparatus in accordance with one embodiment of the present invention using the shoelace of FIG. 1;
  • FIG. 5 is a partial plan view of a component part of the apparatus of FIG. 4.
  • FIG. 6 is a cross-section view of the component part of FIG. 5 taken along line 6,6 in
  • FIG. 5 is a diagrammatic representation of FIG. 5.
  • an elastic string 10 is shown having an outer cover 12 which surrounds an inner core 14.
  • Elastic string 10 is stretchable from a rest state 14 (shown as a solid line in FIG. 1) to an elongated state 14' (shown as a dashed line in FIG. 1).
  • string 10 is shown having a outer cover 12 and inner core 14 formed from a plurality of strands 16.
  • string 10 In its normal state, string 10 has a rest diameter dl , and a decreased diameter d2 when in a stretched state.
  • core 14 stretches and its diameter decreases.
  • Each end of elastic string 10 is terminated in an aglet (not shown), which is made of a hard plastic material to keep outer cover 12 from fraying.
  • outer cover 12 is formed from a plurality of intertwined fiber threads 18 having a plurality of spaces 20 that form an extendible web. When string 10 is stretched, threads 18 extend so that spaces 20 are created between threads 18. Thus, outer cover 12 extends along with inner core 14 when string 10 is stretched. When string 10 is returned to a rest state, outer cover 12 returns to a rest position and spaces 20 close.
  • Outer cover fiber threads 12 are preferably formed from an air permeable, hydrophobic, tetra-channel, wicking fiber material such as Coolmax ® and Coolmax ® EcoMade ® sold by Dupont.
  • wicking fiber material such as Coolmax ® and Coolmax ® EcoMade ® sold by Dupont.
  • Other suitable hydrophobic wicking fibers may be used such as a hollow-core, hydrophobic wicking fiber sold as Thermolite ® by Dupont may be used. These types of fiber materials wick away moisture and trap warm air in its hollow-core fibers.
  • Other suitable types of fibers, such as a Teflon ® or polytetrafluoroethylene fiber material may be used depending on the application.
  • Air permeable, hydrophobic, tetra-channel fibers may be used to wick away moisture from core 14 and reduce friction against the skin as the lace moves during exercise.
  • Hydrophobic fibers such as those used in the Coolmax ® fabric transport water away from the core to an outer layer, where the large surface area of the tetra-channel fibers allow the moisture to evaporate quickly.
  • the fiber material provides great breathability or air permeability, even when wet.
  • these types of fibers resist abrasions and deterioration due to rubbing against other items.
  • the fibers are made from recycled plastic bottles.
  • the outer cover 12 is formed from 100% Coolmax ® .
  • cover 12 may be formed from a blend of Coolmax ® and nylons and other suitable materials.
  • core strands 16 have traditionally been formed from a rubber material.
  • core strands 16 are formed from a elastic polymer material.
  • the elastic polymer is Lycra ® manufactured by Dupont.
  • Lycra ® has a number of advantages over rubber materials, including but not limited to being lightweight, breathable, quick drying, and resistant to bacteria, ultraviolet rays and chlorine. Lycra ® is quick drying and is easily dyable. Lycra ® is able to expand up to 600% and spring back without losing its integrity. Thus, Lycra ® offers many improvements over prior art rubber materials, which may dry out and become brittle, loose its stretching properties and cannot be dyed.
  • the elastic polymer is formed from recycled plastic materials.
  • core strands 16 each having a diameter of about 0.025 inches.
  • strands 16 may be grouped together in groups of various sizes.
  • strands 16 may be made of three groups of five strands each, and may be grouped together by an adhesive or other means or may simply be held together by outer cover 12.
  • string 10 has an outer diameter of approximately 3/25 inches when at rest and a length of about 18 - 30 inches. This allows for a string that is sufficient in length for most users.
  • a shoe 110 is shown having a sole 112 and an upper footwear portion 114 connected thereto.
  • Upper footwear portion 114 includes two flap portions 111 and 113, which in turn include a plurality of eyelets 116 so that portions 111 and 113 define a plurality of apertures 118 through which a string, in the form of a shoelace, 10 has been threaded.
  • string 10 has two free ends 122 which, although not required, are proximate to the front end, i.e. , the end opposite from the heel (not shown), of shoe 10. Free ends 122 are connected to one another by a plastic clamp 124, thereby placing string 10 in the form of a continuous loop.
  • String 10 is threaded through a mechanical locking fastener 126.
  • Locking fastener 126 receives the lace and is configured to releasably lock at least two portions of string 10 in proximity with one another, to thereby secure the lace, and in turn the portions of footwear upper portion 114 through which the lace is threaded, together.
  • a loop segment 128 extends from fastener 126.
  • clamp 124 is in the shape of an open-ended hollow cylinder formed from two halves 130 and 132, which are hinged together along respective longitudinal edges so as to pivot relative to one another about a longitudinal axis represented in FIG. 6 as pivot point P.
  • Halves 130 and 132 may be clamped together by a snap fit provided by beveled flanges 134 and 136 that extend longitudinally along the respective edges of halves 130 and 132 which are opposite the hinged connection.
  • Clamp 124 further comprises lace retention means in the form of a plurality of spiked flanges 138 which extend from an inner surface 140 of the hollow cylinder formed by halves 130 and 132 into the space S within the hollow cylinder.
  • a secondary flange 142 extends out radially from an outer surface 141.
  • half 130 defines two apertures 123 spaced apart by a bridge portion 144 through which lace free ends 122 may be viewed.
  • Flange 142 is curved in cross-section to facilitate the retention of lace loop segment 128. In this way, loop segment 128 may be retained to prevent it from dangling to the side of shoe 110, if desired.
  • each free end 122 may be threaded through a respective aperture 123 and locked in place so as to retain string 10 in clamp 124.
  • the secondary flange may take on one of many forms, and such form is no limitation of this invention so long as the secondary flange is capable of retaining the lace to prevent the loop segment from dangling to the side of the shoe.
