  • Fig. 1 provides a top plan view of a first preferred embodiment of the squared-cord shoe closure system of the present invention shown in a generally open and loose configuration, ready for insertion of the user's foot into the shoe prior to closure.
  • Shoe closure system 10 is positioned on shoe 12 (left foot shoe shown in the example provided) with a lateral side 14 of the shoe and a medial side 16. Heel portion 18 of the shoe is also shown at the top of Fig. 1 with toe portion 20 of the shoe shown at the bottom. Tongue portion 22 of the shoe is shown within and beneath the shoe closure system 10 of the present invention.
  • the overall shoe closure system 10 starts with strap components that are fixed to the heel portion 18 of shoe 12 and extend forward to approximately the middle of the shoe on medial side 16.
  • strap components that are fixed to the heel portion 18 of shoe 12 and extend forward to approximately the middle of the shoe on medial side 16.
  • Those skilled in the art will recognize that the structures described in Fig. 1, with the side strap components positioned on the medial side of the shoe, may be reversed in their entirety to operate on or from the lateral side of the shoe. When operated from the lateral side, the squared- cord components are likewise reversed in orientation across the top or tongue portion of the shoe.
  • the side strap components of the shoe closure system 10 include anchor strap 24 which extends from a point on heel portion 18 of the shoe where it is sewn or otherwise fixed to the structure of the shoe.
  • Anchor strap 24 extends forward around the heel to rear strap buckle 26 where it passes through the buckle and is reversed in direction to end with rear strap pull back portion 28.
  • rear strap pull back portion 28 is secured against anchor strap 24 with attachment surfaces 25a & 25b.
  • Various types of flexible or semi-rigid attachment surfaces may be used to secure rear strap pull back portion 28 tightly against heel portion 18 of the shoe.
  • buckle 26 and anchor strap 24 may be eliminated altogether, with rear strap pull back portion 28 formed from an end of draw strap longitudinal portion 30 to draw the strap portion of the squared-cord system of the present invention longitudinally along the side of the shoe and thereafter be secured (through attachment surface 25b positioned on the strap) directly to attachment surface 25a which may be fixed directly to an area of the heel portion 18 of the shoe 12.
  • the longitudinal pull effected by the strap arrangement described above operates on rear strap buckle 26 which is connected to and forms the end point for draw strap longitudinal portion 30.
  • the draw strap that extends from rear strap buckle 26 to cord clasp 38 is made up of two portions; a first longitudinal portion, draw strap longitudinal portion 30; and a second lateral portion, draw strap lateral portion 36.
  • the orientation of the overall strap is altered at angle loop buckle 32.
  • Angle loop buckle 32 is held in place by holding strap 34 which extends from buckle 32 to a point on the side of the shoe (see Fig. 2) where it is secured either to the side of the shoe or at a point where the sole of the shoe meets the upper of the shoe.
  • angle loop buckle 32 may simply be secured to the side of the shoe with a rivet or other attachment component (not shown) fixing it in the same position shown in Figs. 1 & 2.
  • the strap and cord arrangement shown in Figs. 1 & 2 is structured to be removable and reversible (switching from the medial to the lateral side of the shoe).
  • draw strap lateral portion 36 extends across the tongue portion 22 of the shoe in a lateral orientation to a point where it engages the squared-cord components of the present invention.
  • the length of draw strap lateral portion 36 may be independently adjusted by moving the position of cord clasp 38 on the end of the strap.
  • the squared-cord structure itself is made up of a single length of draw cord that includes draw cord longitudinal portion 40, draw cord rear lateral portion 42, and draw cord forward lateral portion 44.
  • This single length of draw cord extends from cord end post 46a all the way through to cord end post 46b.
  • Cord end posts 46a & 46b are positioned on the shoe within cord end eyelets 48a & 48b. The manner in which these end sections of the cord are inserted into and secured within the end eyelets may vary from a fixed sewn-in attachment structure to the preferred toggle post configuration shown in broken lines in Fig. 1.
  • the single draw cord structure of the first preferred embodiment extends between the end posts and end eyelets through fixed pulleys 50a & 50b.
  • the draw cord slides easily through fixed pulleys 50a & 50b as well as sliding through cord clasp 38. Additional detail regarding the structures of the fixed pulleys and the cord clasp are provided below. Alternate structures that may be positioned where fixed pulleys 50a & 50b are shown in Fig. 1, are also described in more detail below.
  • Tongue cord guide 49 may be secured to an upper portion of tongue 22 of the shoe to prevent the tongue from sliding down below the closure system in both the loosened and tightened condition.
  • Elastic strap 35 may be positioned across the tongue 22, each end of which is attached to opposing eye stays of the shoe to preference together the sides of the shoe (at the eye stays) when the squared-cord closure system is loose.
  • FIG. 1 In the generally loose configuration shown in Fig. 1, it can be seen how the squared- cord components of the system of the present invention may be easily attached to and removed from the basic shoe structure, such that the squared-cord may be removed and replaced for functional wear or for aesthetic purposes.
  • Cord clasp 38 may be easily removed from draw cord longitudinal portion 40 and the ends of the cord 46a & 46b may be easily removed from the end eyelets 48a & 48b positioned on the shoe 12.
  • Fig. 2 is a side elevational view of the first preferred embodiment of the squared-cord shoe closure system of the present invention, as shown above in Fig. 1, disclosing the manner of redirecting the draw strap from a lateral orientation to a longitudinal orientation.
  • Shoe closure system 10 is again shown structured on shoe 12 with the view of Fig. 2 being of the medial side 16 of the shoe. Heel portion 18 and toe portion 20 of the shoe are also disclosed. The top of tongue portion 22 of the shoe is seen in profile.
  • Rear strap buckle 26 may be a simple double loop buckle as shown, or may be structured as a friction imparting buckle to facilitate maintaining the pull strap in a secure position.
  • a further alternate embodiment wherein rear strap buckle 26 is omitted entirely and a single strap extends back to attachment surface 25a is also anticipated and described above.
  • cord end eyelets 48a & 48b positioned in the eye stay of the shoe adjacent the tongue portion 22 through the upper of the medial side 16 of the shoe.
  • cord end posts Positioned within eyelets 48a & 48b are cord end posts (not shown in Fig. 2) from which extend draw cord rear lateral portion 42 and draw cord forward lateral portion 44.
  • Draw cord lateral portions 42 & 44 extend over and across tongue portion 22 of the shoe.
  • draw strap lateral portion 36 extends over and across tongue portion 22 of the shoe to its point of attachment to draw cord longitudinal portion (not shown).
  • Optional elastic strap 35 is shown generally below the area where draw strap lateral portion 36 crosses over tongue 22.
  • Optional tongue cord guide 49 is also seen (broken line form) in profile in the view of Fig. 2.
  • FIG. 3 is the same top plan view of the first preferred embodiment of the squared-cord shoe closure system shown in Fig. 1, but in a closed and tightened configuration after the user's foot has been inserted into the shoe and the single pull longitudinal motion has been effected to draw the shoe closed.
  • shoe closure system 10 is positioned on shoe 12 between lateral side 14 and medial side 16 of the shoe. Heel portion 18 of the shoe is again shown at the top of Fig. 3 with toe portion 20 shown at the bottom. Tongue portion 22 of the shoe is shown within and beneath the shoe closure system 10 of the present invention.
  • rear strap pullback portion 28 is drawn back against rear strap buckle 26 which pulls draw strap longitudinal portion 30 as described above.
  • Rear strap pull back portion 28 is removably secured to anchor strap 24 which extends from a point on heel portion 18. As indicated above, various mechanisms for securing rear strap pull back portion 28 to anchor strap 24 or to an attachment surface on heel 18 are anticipated.
  • draw strap longitudinal portion 30 is redirected by angle loop buckle 32 held in place by holding strap 34.
  • Draw strap longitudinal portion 30 transitions into draw strap lateral portion 36 which is secured to cord clasp 38 as shown.
  • cord clasp 38 has moved laterally across the shoe, pulling with it draw cord longitudinal portion 40.
  • the process of pulling on draw cord longitudinal portion 40 angles the longitudinal cord and thereby pulls on and shortens both draw cord rear lateral portion 42 and draw cord forward lateral portion 44.
  • These cord components slide through fixed pulleys 50a & 50b at the corners of the squared-cord configuration.
  • Clasp 38 is generally configured as a hook device with a flat base 35 that includes strap length adjustment and securement apertures 37. Hook portion 39 of clasp 38 turns back on base 35 leaving a vertical gap sufficient to allow cord 40 to slide into and become engaged by clasp 38.
  • the configuration shown in Figs. 4A & 4B allows for the clasp to be removably positioned about the cord for reorientation or replacement as needed.
  • Figs. 5A - 5C provide additional detail on three alternate embodiments of the sliding corner point cord securement devices.
  • Fig. 5A discloses fixed pulley 50a as shown in Figs. 1 & 3.
  • fixed pulley 50a is seen to be made up of pulley block 60 which holds rotatable cylinder 62, maintained in place by pulley axle 61.
  • Pulley axle 61 serves as both the axle for the pulley and the manner of securing fixed pulley 50a to the upper of shoe 12.
  • Pulley axle 61 may be a rivet for example that is secured to the shoe through fixed pulley 50a.
  • the upper surface of the pulley block 60 includes a recessed portion 63 to receive the head of the pulley axle/rivet as shown.
  • cord 40 is threaded through block 60 of fixed pulley 50a in a manner that prevents its easy removal from or rethreading through the corner or side point structure.
  • Alternate embodiments of the system shown in Figs. 1 - 3 reorient the fixed pulley structure 50a such that the open side of pulley block 60 is directed outward in the corner point position.
  • cord 40 may simply be secured around the corner point pulleys by drawing or stretching the cord around from the outside of the rotatable cylinder 62.
  • Fig. 5B presents a simpler manner of effecting corner or side point securement of cord 40 by providing a post structure that is again secured to the upper of shoe 12 in the manner of a rivet or the like.
  • Corner post 70a shown in Fig. 5B comprises post pin 72 at one end of which is configured post cap 73.
  • Rivet portion 71 is shown extending through the material of shoe 12 in a manner that secures corner post 70a in a tight upright configuration where it retains cord 40 as long as the cord is in a tensioned state. In a loose configuration, cord 40 may more easily be removed from corner post 70a in a manner that may be desirable in a number of the preferred embodiments.
  • Fig. 5C shows yet another configuration for creating a corner or side point for cord 40 in a manner that effects the right angle reorientation of the cord at the corners or sides of the squared-cord profile.
  • Fig. 5C discloses corner or side point aperture 77a which is made up primarily of a simple grommet 76 secured through the upper of shoe 12 in a manner that allows draw cord lateral portion 42 (for example) to pass upward through grommet 76 before exiting as draw cord longitudinal portion 40 where it is then directed down the length of the shoe to a corresponding aperture grommet on the lower portion of the shoe near the eye stay and the base of the tongue.
  • FIG. 6 a top plan view of a second preferred embodiment of the squared-cord shoe closure system of the present invention incorporating a single lateral pull with securement on the side of the shoe, shown in an open and loose configuration ready for insertion of the user's foot in the shoe prior to closure.
  • Shoe closure system 80 is positioned on shoe 12 (left foot shoe shown in the example of Fig. 6) with a lateral side 14 of the shoe and a medial side 16. Heel portion 18 and toe portion 20 are also shown in their respective orientations in Fig. 6. Tongue 22 of the shoe is again shown within and beneath the shoe closure system 80 of the present invention.
  • the overall shoe closure system 80 eliminates the strap components that extended longitudinally down the side of the shoe and were fixed to a point on the heel of the shoe as in the first preferred embodiment described above.
  • This second embodiment instead provides a single shorter lateral strap that is secured to the cord in a manner similar to the first preferred embodiment, but which is structured to be attached to a securement point on one side of the mid-sole portion of the shoe.
  • the squared-cord arrangement shown in Fig. 6 comprises a closed loop structure wherein the cord is made up of draw cord first longitudinal portion 82a, draw cord forward lateral portion 82b, draw cord second longitudinal portion 82c, and draw cord rear lateral portion 82d.
  • the cord material is secured back onto itself with cord crimp connector 79, preferably placed at a midpoint on draw cord forward lateral portion 82b.
  • the cord in this configuration is established in a rectangular geometry by threading through or securing around corner points that form the square.
  • Each of the alternate corner points described above with the first preferred embodiment may also be applicable to the embodiment shown in Fig. 6.
  • Securement strap 81 includes pull tab 87, aperture array 85, and strap clasp 83.
  • Securement strap 81 is designed to be secured (with strap clasp 83) alternately to draw cord first longitudinal portion 82a or draw cord second longitudinal portion 82c depending upon the direction of the lateral pull that the user desires to implement.
  • Securement assemblies are therefore positioned on each side of the shoe to allow the user to draw laterally across the shoe from the outside (the lateral side of the shoe) to the medial side of the shoe, or to reverse the process directing the tightening strap laterally from the medial side towards the outside (lateral) of the shoe.
  • Cord guard 86 provides an optional connection point on draw cord second longitudinal portion 82c onto which strap clasp 83 may be alternately secured to effect the reverse of the lateral draw direction (using securement post assembly 88b instead of 88a).
  • FIG. 7 represents the second preferred embodiment shown in Fig. 6 in a tightened and closed configuration.
  • Securement strap 81 is drawn laterally across the shoe pulling on draw cord first longitudinal portion 82a and thereby tightening and shortening draw cord rear lateral portion 82d and draw cord forward lateral portion 82b. This single pull lateral movement compresses the lateral side 14 of the shoe towards the medial side 16.
  • securement strap 81 When securement strap 81 is drawn to the side, it extends down and over securement post assembly 88a.
  • the user hooks one of the apertures in aperture array 85 over the hook post on securement post assembly 88a in order to fix the strap in its lateral tensioned position.
  • Any number of apertures may be configured in linear aperture array 85.
  • the closed loop draw cord (made up of cord portions 82a - 82d) is preferably an elastic or semi-elastic cord that when tightened and pulled in the manner shown in Fig. 7, imparts a residual tension in the cord that serves to not only draw the sides of the shoe together over tongue 22, but also to maintain a snug fit to the shoe and to effect a tension force on securement strap 81 that helps to maintain it in position on securement post assembly 88a.
  • the elasticity of the draw cord should be a balance between having a residual tension in the cord once drawn across the shoe and attached in the manner described above, and the ability to draw the sides of the shoe together over the tongue by effectively shortening draw cord forward lateral portion 82b and draw cord rear lateral portion 82d. Too much elasticity and the cord merely stretches once securement strap 81 is drawn into position without drawing the sides of the shoe tightly enough across the tongue. Not enough elasticity and there is no residual tension remaining in the cord once it is drawn across and secured. Various cord structures combining interior elastic fibers within a woven polymer thread sheath meet this preferred balance of elastic properties. It should also be noted that the closed loop configuration shown in Figs. 6 & 7 may be implemented with the longer draw strap configuration positioned on the side of the shoe shown and described with Figs. 1 - 3.
  • FIGs. 8A - 8C for a third preferred embodiment of the squared-cord shoe closure system of the present invention incorporating a single lateral pull with securement on the side of the shoe, supplemented with an additional center eye stay closure action.
  • retainer bridge 91 is positioned on one side of the shoe opposite that of securement post assembly 88a.
  • eye stay aperture 93 is structured through the eye stay on the same side of the shoe as securement post assembly 88a.
  • this third preferred embodiment may be manufactured or implemented in a mirror image of the arrangement shown in Figs. 8A - 8C (i.e. the medial and lateral sides being switched) the structure does not generally lend itself to being user-reversible on a given shoe as does the previously described second preferred embodiment.
  • Securement strap 81 in this third preferred embodiment is attached to draw cord second longitudinal portion 82c through eye stay aperture 93 with strap clasp 83 as shown in Fig. 8A.
  • securement strap 81 rather than simply being laterally drawn across the shoe, securement strap 81 initially passes under and around retention bridge 91 before it is drawn back across the shoe and attached to securement post assembly 88a.

Abstract

L'invention concerne un système permettant de fixer des chaussures aux pieds à l'aide d'un ou de deux agencements de fermeture de chaussure à tirage. Chaque mode de réalisation du système utilise un agencement de cordon carré qui s'étend entre le côté latéral et le côté médian de la chaussure. Les divers modes de réalisation comprennent une ou deux bandes de traction reliées à une ou plusieurs parties de cordon carré pour tirer et serrer les côtés de l'agencement de cordon carré. Une seule bande de tirage dans un premier mode de réalisation est redirigée d'une orientation latérale à une orientation longitudinale où elle est tirée vers l'arrière et fixée sur la partie talon de la chaussure. D'autres modes de réalisation tirent deux bandes de traction plus courtes parallèles latéralement vers des points de fixation sur les côtés de la chaussure. D'autres modes de réalisation alternatifs tirent une bande de traction longitudinalement le long d'une ligne médiane au sommet de la chaussure jusqu'à un point de fixation sur l'agencement de cordon carré.
