  [0003] The present invention provides a number of preferred embodiments within an overall system for securing a shoe to a foot that utilizes a single closure shoe closure arrangement. Each of the various alternative embodiments of the present invention broadly extends between the outer and inner surfaces of the shoe across the shoe tongue or top, a broadly “squared cord” arrangement (“Squared-cord” arrangement). ) Is used. A “squared string” array generally refers to a generally rectangular array of open or closed loops of strings that extend around a series of corner or side-up strapping devices. Although substantially rectangular, the rectangular string arrangement described herein need not define a right angle to a corner or have opposite sides of equal length. The array may be trapezoidal or have sides that are curved inwardly or outwardly without departing from the “substantially rectangular” or “squared string” array definition provided in this disclosure. It may be. Various alternative embodiments provide for one or more squared string structures to retract the sides of the squared string array, thereby shrinking and tightening the sides of the squared string array from its original relaxed configuration. A single tightening strap is provided. Various structures for tightening or pulling one or more rectangular strings and various structures for allowing the strings to slide or move from their original configuration are described.

  [0004] The described embodiments utilize a side strap that tightens one side of a squared lace configuration to achieve shoe closure. The single handle strap of the first embodiment is redirected from a lateral orientation (direction across the shoe) to a longitudinal orientation (direction along the shoe), where the strap is longitudinal. It is tightened back in action and secured to the side and / or heel of the shoe. An alternative embodiment is to pull a shorter tightening strap laterally to a fixed point below the tongue section on the side of the shoe, without the need for a longitudinal pulling action. A further alternative embodiment pulls the tightening strap longitudinally along the centerline of the top of the shoe to a fixed point returning onto the squared strap array. Again, as before, various structural mechanisms have been envisioned and described to accomplish the tightening of the squared string configuration together.

A structure for achieving a determined single length puller to tighten a plurality of strings in a double squared string array is shown, and the system is shown in an open and relaxed configuration. [0020] FIG. 12 is a detailed partial cross-sectional view of a pull strap attachment structure for a sixth preferred embodiment of the squared lace shoe closure system of the present invention provided in FIG. [0021] FIG. 13 is a detailed partial cross-sectional view of a pull strap attachment structure for the seventh preferred embodiment of the squared lace shoe closure system of the present invention provided in FIG.

  [0022] Referring first to FIG. 1, which provides a first preferred embodiment of the squared lace shoe closure system of the present invention, where the system places a user's foot into the shoe prior to closure. Shown in a generally open relaxed configuration that can be inserted at any time. The shoe closure system 10 is disposed on a shoe 12 (the left foot shoe is shown in the example provided) having an outer surface 14 and an inner surface 16 of the shoe. Further, a shoe heel 18 is shown on the upper side of FIG. 1 and a shoe toe 20 is shown on the lower side. A shoe tongue 22 is shown below in the shoe closure system 10 of the present invention.

  [0023] The overall shoe closure system 10 begins with a strap component that is secured to the heel 18 of the shoe 12 and extends the inner side 16 forward to the middle of the shoe. For those skilled in the art, the structure depicted in FIG. 1 with respect to the side strap components located on the inner side of the shoe may be flipped over to act on or from the outer side of the shoe. Will be recognized. When acting from the outside, the squared lace component is also reversed in orientation across the top or tongue of the shoe.

  [0024] The side strap component of the shoe closure system 10 includes an anchor strap 24 extending from a point on the shoe heel 18 that is sewn to the shoe structure. The anchor strap 24 extends forward around the heel to the rear strap buckle 26, where it reverses direction when passing through the buckle and ends at the rear strap pull-back portion 28. In a preferred embodiment, the rear strap pullback 28 is secured against the anchor strap 24 using attachment surfaces 25a and 25b. Various types of flexible or semi-rigid attachment surfaces could be used to secure the rear strap pullback 28 against the heel 18 of the shoe. In some embodiments, particularly those involving small shoes such as children's, the buckle 26 and anchor strap 24 are eliminated entirely, and the rear strap retracting portion 28 formed from the end of the tightening strap longitudinal portion 30 includes a book The strap part of the inventive squared string system is pulled longitudinally along the side of the shoe and then directly onto the attachment surface 25a (which is placed on the strap) which is fixed directly to the area of the heel 18 of the shoe 12. It may be fixed by the attachment surface 25b.

  [0025] In the preferred embodiment shown in FIG. 1, the longitudinal pull achieved by the strap arrangement described above is connected to the tightening strap longitudinal portion 30 to form the end point of the longitudinal portion 30. Acting on the rear strap buckle 26. The tensioning strap extending from the rear strap buckle 26 to the clasp 38 has two parts: a tensioning strap longitudinal part 30 which is a first longitudinal part and a tensioning strap lateral part 36 which is a second lateral part. It consists of The direction of the entire strap is changed by an oblique loop buckle 32. The slanted loop buckle 32 is held in place by a retaining strap 34 that extends from the buckle 32 to a point on the side of the shoe (see FIG. 2) where it is secured to the side of the shoe. Or fixed at the point where the sole of the shoe meets the upper of the shoe. Instead, the diagonal loop buckle 32 is simply secured to the side of the shoe with a rivet or other attachment component (not shown) secured to it in the same position shown in FIGS. It may be. The strap and lace arrangement shown in FIGS. 1 and 2 is constructed to be removable and reversible (switchable from the inner surface to the outer surface of the shoe).

  [0026] After the tightening strap changes its orientation within the slanted loop buckle from the longitudinal orientation of the tightening strap longitudinal portion 30 to the lateral orientation of the tightening strap lateral portion 36, the strap is attached to the strap clasp 38 It is terminated. In a preferred embodiment, the tightening strap lateral portion 36 extends across the shoe tongue 22 in a lateral orientation to the point where it engages the rectangular strap component of the present invention. In the preferred embodiment shown in FIG. 1, the length of the tightening strap lateral portion 36 can be independently adjusted by moving the position of the strap clasp 38 at the end of the strap.

  [0027] As can be seen from FIG. 1, the squared lace structure itself is a single length of cinching string that includes a lacing string longitudinal portion 40, a lacing strap rear lateral portion 42, and a tightening cord forward lateral portion 44. It is configured. This single length of the tightening string extends all the way from the string end strut 46a to the string end strut 46b. The string end struts 46a and 46b are disposed within the string end eyelets 48a and 48b on the shoe. The manner in which these end sections of the string are inserted into the end eyelet and secured therein is the fixed stitching attachment structure to the preferred toggle-type strut configuration shown in dashed lines in FIG. May be different.

  [0028] The single tightening strap structure of the first preferred embodiment extends between the end struts and the end eyelets through the stationary pulleys 50a and 50b. The tightening string easily slides through the fixed pulleys 50a and 50b and also through the clasp 38. Additional details regarding the construction of the fixed pulley and clasp are provided below. Alternative structures that may be placed where the fixed pulleys 50a and 50b of FIG. 1 are shown are also described in more detail below.

  [0029] Two additional structures, shown in dashed lines in FIG. 1, illustrate components that can optionally be incorporated into the system to facilitate smooth functionality. A tongue strap guide 49 may be secured to the upper portion of the shoe tongue 22 to prevent the tongue from sliding down below the closure system in either the relaxed state or the tightened state. An elastic strap 35 is placed across the tongue 22 and its ends are attached to the opposite eyestays of the shoe so that the sides of the shoe are attached to the eyestay when the square lace shoe closure system is relaxed. E) You may be attracted.

  [0030] In the generally relaxed configuration shown in FIG. 1, it can be seen how the squared lace components of the system of the present invention can be easily attached to and removed from the underlying shoe structure. As a result, the squared string can be removed and replaced due to functional wear or for aesthetic purposes. The strap clasp 38 can be easily removed from the tightening strap longitudinal portion 40 and the strap ends 46a and 46b can be easily removed from the end eyelets 48a and 48b disposed on the shoe 12.

  [0031] Reference is now made to FIG. 2, which is a side view of the first preferred embodiment of the squared lace shoe closure system of the present invention shown above in FIG. A method of reorienting from a directional orientation to a longitudinal orientation is disclosed. The shoe closure system 10 is again shown as being constructed on the shoe 12 and the perspective of FIG. 2 is the inner surface 16 of the shoe. A shoe heel 18 and toe 20 are also disclosed. The top of the shoe tongue 22 has an outline.

  [0032] The anchor strap 24 is shown in this figure as being almost covered by the attachment surface 25a, and the anchor strap 24 is secured to the heel 18 of the shoe and to or around the heel. And then extends forward in the longitudinal direction along the length of the shoe toward the rear strap buckle 26. The anchor strap 24 then turns rearwardly through the rear strap buckle 26 and terminates at the rear strap pullback 28. As described above, various mechanisms are envisioned for securing the back strap pullback 28 onto the anchor strap 24 or tightly affixing to the anchor strap 24. The rear strap buckle 26 may be a simple double loop buckle as shown, or may be constructed as a friction imparting buckle to facilitate maintaining the tightening stop in a fixed position. . Further alternative embodiments in which the entire rear strap buckle 26 is omitted and a single strap extends back to the attachment surface 25a are also envisioned and described above.

  [0033] Extending forward of the rear strap buckle 26 is a tensioning strap comprised of a tensioning strap longitudinal portion 30 and a tensioning strap lateral portion 36. The diagonal loop buckle 32 achieves a change from the longitudinal direction to the lateral direction for the tightening strap. Holding the diagonal loop buckle 32 in place at about the midpoint of the inner surface 16 of the shoe 12 is a holding strap 34, which in one preferred embodiment, from the buckle to the inner surface. 16 to the fixed attachment point of the contact surface between the upper and the shoe sole 54 or to a tab (not shown) extending upward from the joint of the upper and the outsole.

  [0034] In the fully open and relaxed configuration shown in FIG. 2, many of the functional squared lace components of the shoe closure system 10 are not visible. From the viewpoint side of FIG. 2, lace end eyelets 48 a and 48 b arranged in the shoe eyestay through the upper of the inner side surface 16 of the shoe adjacent to the tongue 22 can be seen. Cord end struts (not shown in FIG. 2) are disposed in the eyelets 48a and 48b, from which the tightening cord rear lateral portion 42 and the tightening cord front lateral portion 44 extend. The tightening strap lateral portions 42 and 44 extend across the shoe tongue 22. Similarly, the tightening strap lateral portion 36 extends across the shoe tongue 22 to its point of attachment to the tightening strap longitudinal portion (not shown). An optional elastic strap 35 is generally shown below the area where the tightening strap lateral portion 36 straddles the tongue 22. From the viewpoint of FIG. 2, the contour (dashed line form) of the optional tongue string guide 49 can also be seen.

  [0035] Referring now to FIG. 3, which is the same top view of the first preferred embodiment of the squared lace shoe closure system shown in FIG. Is shown in a closed clamping configuration after a single pull longitudinal operation has been performed to tighten and close the shoe. As before, the shoe closure system 10 is disposed on the shoe 12 between the outer surface 14 and the inner surface 16 of the shoe. The shoe heel 18 is again shown on the upper side of FIG. 3 and the toe 20 is shown on the lower side. The shoe tongue 22 is shown below in the shoe closure system 10 of the present invention.

  [0036] In the closed configuration shown in FIG. 3, the rear strap pullback 28 is tightened rearward against the rear strap buckle 26, which pulls the tightening strap length 30 as described above. The rear strap pullback 28 is removably secured to an anchor strap 24 that extends from a point on the collar 18. As suggested above, various mechanisms for securing the rear strap pullback 28 to the anchor strap 24 or to the attachment surface on the collar 18 are envisioned.

  [0037] The longitudinal pull of the cinching strap longitudinal portion 30 is redirected by an oblique loop buckle 32 held in place by a retaining strap 34. The tightening strap longitudinal portion 30 transitions to a tightening strap lateral portion 36 that is secured to the clasp 38 as shown. In the closed configuration shown in FIG. 3, the tie clasp 38 has been moved across the shoe laterally while pulling the cinching string longitudinal portion 40 along with the clasp. The process of pulling the tensioning cord longitudinal portion 40 causes the longitudinal cord to be skewed, thereby pulling and shrinking both the tensioning cord rear side portion 42 and the tensioning cord front side portion 44. These lace components slide through the square fixed pulley configuration corner fixed pulleys 50a and 50b. The process of pulling and retracting the back and front lateral portions 42 and 44 of the tightening strap serves to pull the two sides of the shoe together across the shoe tongue 22, thereby tightening the shoe and securing the shoe to the wearer's foot. To do. Also shown in FIG. 3 is an optional elastic strap 35 and tongue strap guide 49.

  [0038] Reference is now made to FIGS. 4A and 4B, which provide additional details about the clasp 38. FIG. The clasp 38 is generally configured as a hook device having a flat base 35 that includes a strap length adjustment and a fixed opening 37. The hook portion 39 of the clasp 38 is folded in half to the base 35 leaving a vertical gap sufficient for the string 40 to be engaged by the slip clasp 38. The configuration shown in FIGS. 4A and 4B allows the clasp to be removably placed around the lace in preparation for redirection or replacement as needed.

  [0039] FIGS. 5A-5C provide additional details about three alternative embodiments of the sliding corner strap anchoring device. FIG. 5A discloses the fixed pulley 50a shown in FIGS. In this partial cross-sectional view, it can be seen that the fixed pulley 50a comprises a pulley block 60 holding a rotatable cylindrical body 62 which is maintained in place by a pulley axle 61. The pulley axle 61 serves as an axle for the pulley and also serves as a way to fix the fixed pulley 50 a to the upper of the shoe 12. The pulley axle 61 may be, for example, a rivet that is fixed to a shoe through a fixed pulley 50a. The upper surface of the pulley block 60 preferably includes a recess 63 for receiving the pulley axle / rivet head as shown. In the embodiment shown in FIG. 5A, the string 40 is a fixed pulley in a manner that prevents it from easily falling off the corner or side point structure or passing through the corner or side point structure again. It is passed through the block 60 of 50a. An alternative embodiment of the system shown in FIGS. 1-3 reorients the fixed pulley structure 50a so that the open side of the pulley block 60 points outward at the corner position. In this alternative way of orienting the fixed pulleys 50a and 50b, the string 40 is simply fixed around the corner pulley by hooking or tensioning the string around the rotatable cylinder 62 from the outside. It may be.

  [0040] FIG. 5B presents a simpler way of achieving the anchoring of the corners or sides of the lace 40 by providing a strut structure, again in which the strut structure is riveted or otherwise. Fixed to the upper. A square column 70 a shown in FIG. 5B includes a column pin 72, and one end of the column pin 72 is formed on a column cap 73. The rivet portion 71 is shown extending through the material of the shoe 12 in a manner that secures the square post 70a in a strict upright configuration, where the square post 70a ties the string 40 and the string is tensioned. Hold as long as it is in the state of hanging. The lace 40 can be more easily removed from the angular strut 70a in a relaxed configuration in the manner desired in many preferred embodiments.

  [00041] In addition, FIG. 5C shows yet another configuration for creating a corner or edge point for string 40 in a manner that achieves a right-angle reorientation of the string at the corner or edge of the squared string profile. Is shown. FIG. 5C discloses a corner or side point opening 77a, which is primarily comprised of a simple grommet 76, which pulls out (for example) the drawstring lateral portion 42 to pass the grommet 76 upward. In a manner that can then be pulled out as a tightening string longitudinal portion 40 and then directed down the length of the shoe to the corresponding opening grommet near the eyestay in the lower portion of the shoe and near the base of the tongue, It is fixed through the upper of the shoe 12.

  [0042] Various alternative embodiments for corners or on-side points of the squared string system of the present invention disclosed in FIGS. 5A-5C may benefit from simplicity of construction and no friction around the corner points. There is a balance between the benefits of exercise. Each of the specific configurations described enjoys certain benefits over others in certain shoe types and in certain shoe sizes. It is also possible to mix various types of corners or side points in a given square string arrangement.

  [0043] Referring now to FIG. 6, which is a plan view of a second preferred embodiment of the squared lace shoe closure system of the present invention incorporating a single lateral puller with fixation to the side of the shoe. In this figure, the system is shown in an open relaxed configuration where the user's foot can be inserted at any time into the shoe prior to closure. The shoe closure system 80 is disposed on a shoe 12 (the left foot shoe is shown in the embodiment of FIG. 6) having an outer surface 14 and an inner surface 16 of the shoe. FIG. 6 also shows the heel part 18 and the toe part 20 in their respective directions. The shoe tongue 22 is also shown below in the shoe closure system 80 of the present invention as before.

  [0044] In a second preferred embodiment shown in FIG. 6, the overall shoe closure system 80 is longitudinally down the side of the shoe as in the first preferred embodiment described above. Eliminates strap components that are extended and secured to the point of the heel of the shoe. Instead, the second embodiment is configured to be secured to the lace in a manner similar to the first preferred embodiment, but attached to a securing point on one side of the shoe midsole. A single short lateral strap is provided.

  [0045] The squared string arrangement shown in FIG. 6 comprises a closed loop structure, the string being a tightening string first longitudinal portion 82a, a tightening string front lateral portion 82b, a tightening string second longitudinal portion 82c, and a tightening It is comprised by the string back horizontal part 82d. The string material is fixed back to the string material itself by a string crimp connector 79, which is preferably installed at an intermediate point on the tightening string front lateral portion 82b. In this configuration, the string is established in a rectangular geometry by passing through or fixing around corners forming a square. The embodiment shown in FIG. 6 has four fixed pulleys 84a-84d constructed in the manner described above in connection with FIG. 5A for the first preferred embodiment. Each of the alternative corner points described above with respect to the first preferred embodiment is also applicable to the embodiment shown in FIG.

  [0046] A securing strap 81 includes a pull tab 87, an aperture array 85, and a strap clasp 83. Depending on the direction of the lateral pull that the user wishes to perform, the fixing strap 81 may tighten the tightening string first longitudinal portion 82a or alternatively the tightening string second longitudinal portion 82c (with the strap fastener 83). ) Designed to be fixed. Thus, the tightening strap can be placed laterally so that the user can tighten the shoe across the shoe laterally from the outside of the shoe (the outer side of the shoe) to the inner side of the shoe or by reversing the process. A fixed strut assembly is disposed on each side of the shoe so that it can be directed outward (outside) from the inner side of the shoe. A string guard 86 provides an optional connection point on the tightening string second longitudinal portion 82c and instead a strap clasp 83 is secured thereon (use 88b instead of the fixed strut assembly 88a). ) Reversal of the lateral tightening direction can also be achieved.

  [0047] A way to connect the fixation strap 81 to the side of the shoe is provided by one of the fixation strut assemblies 88a and 88b (in the orientation shown in FIG. 6) to tighten the fixation strap 81 laterally. Beginning by pulling across the second longitudinal portion 82c. The manner in which the locking mechanism is utilized is described in further detail below with reference to FIG. Tan strap guide 89 and elastic band 75 are again shown in dashed lines as optional additions to shoe closure system 80. In the open configuration shown in FIG. 6, the elastic strap 75 retains a certain amount of tension in the system that draws the sides of the shoe opening and the eyestays of the shoe together even when the lace closure system is not tightened. It is shown that it is arranged below the fixing strap 81 in a manner. FIG. 6 discloses that the tongue strap guide 89 is also arranged in a manner similar to that of the first preferred embodiment described above, and the shoe tongue 22 is caused by the residual tension of the tension strap rear lateral portion 82d. It is kept on top.

  [0048] Reference is now made to FIG. 7 representing the second preferred embodiment shown in FIG. 6 in a clamped closed configuration. The fixing strap 81 is tightened across the shoe in the lateral direction while pulling the tightening string first longitudinal portion 82a and tightening and contracting the tightening string rear side portion 82d and the tightening string front side portion 82b. This single pull lateral movement compresses the shoe outer surface 14 toward the inner surface 16. When the fixation strap 81 is tightened to the side, it extends over the fixation post assembly 88a. The user hooks one of the apertures in the aperture array 85 to the hook column on the fixed column assembly 88a to fix the strap in its laterally tensioned position. Any number of openings may be formed in the linear opening array 85.

  [0049] In the preferred embodiment of the present invention shown in FIGS. 6 and 7, the closed loop tensioning strap (comprising strap portions 82a-82d) is tightened and pulled in the manner shown in FIG. In some cases, residual tension is applied to the straps to not only serve to draw the sides of the shoe together on the tongue, but also to maintain a close fit with the shoe and to apply tension to the fixing strap 81 to fix the support strut assembly 88a. An elastic or semi-elastic string that also serves to help maintain the strap in place above is desirable. As will be appreciated by those skilled in the art, the elasticity of the lacing strap is determined by having a residual tension within the lace when tightened across the shoe and applied in the manner described above, and the lacing strap anterior lateral portion 82b and the lacing strap rearward. There must be a balance between the ability to draw the sides of the shoe together on the tongue by effectively shrinking the lateral portion 82d. If it is excessively elastic, once the fixing strap 81 is tightened into place, the strap simply stretches without pulling the shoe sides across the tongue sufficiently tightly. If the elasticity is not sufficient, there is no residual tension remaining in the string when the string is tightened across and secured. Various cord structures combining inner elastic fibers within a woven polymer yarn sheath satisfy this balance of preferred elastic properties. It should also be noted that the closed loop structure shown in FIGS. 6 and 7 uses an elongate pull strap placed on the side of the shoe shown and described in connection with FIGS. 1-3. May be implemented.

  [0050] Next, a third preferred embodiment of the squared lace shoe closure system of the present invention incorporating a single lateral puller with attachment to the side of the shoe and supplemented with an additional central eyestay closure action. Reference is made to FIGS. 8A-8C for embodiments. In FIG. 8A, the retainer bridge 91 is disposed on one side surface opposite to the fixed column assembly 88a of the shoe. In addition, an eye stay opening 93 is constructed through the eye stay on the same side as the fixed post assembly 88a of the shoe. This third preferred embodiment may be manufactured or implemented in a mirror image of the arrangement shown in FIGS. 8A-8C (ie, the inside and outside sides are interchanged), but the structure is generally As with the second preferred embodiment described above, it is not suitable to allow user reversal with a given shoe.

  [0051] The fixation strap 81 in this third preferred embodiment is attached to the tightening string second longitudinal portion 82c with a strap clasp 83 through the eyestay opening 93 as shown in FIG. 8A. ing. In this embodiment, the fixation strap 81 is not simply tightened across the shoe in the lateral direction, but first passes under the retention bridge 91 and then crosses the shoe and then turns back over the fixation post assembly. Attached to 88a. This additional tension point on the first side of the shoe (outer side 14 in the illustrated embodiment) straddles the shoe tongue 22 and draws the two sides of the shoe opening and the shoe eyestay together. Provides power. Again, there must be a balance of the elastic properties of the tightening straps comprised of the strap portions 82a-82d, which provide the residual tension in the strap and yet the two sides of the shoe It provides an inelastic strength sufficient to attract.

  [0052] FIG. 8B is the same view of the shoe 12, but the squared lace shoe closure system 80 is shown after the user has advanced the locking process approximately halfway. At this point in the process, the securing strap 81 pulls the midpoint of the tightening strap second longitudinal portion 82c through the eyestay opening 93, thereby causing each side portion of the squared strap array to begin to draw the sides of the shoe together. I just pulled it. The fixing strap 81 extends under the retention bridge 91 before being folded back around the retention bridge 91 toward the opposite side of the shoe. The eyestay opening 93 is wide enough to allow the strap clasp 83 to pass along with the engaging portion of the tightening string second longitudinal portion 82c.

  [0053] FIG. 8C shows the completion of the fixation process for the third preferred embodiment, where the fixation strap 81 is folded around the retention bridge 91 across the shoe and attached to the fixation post assembly 88a. It extends to the point. This arrangement provides two compression closure forces across the top of the shoe, the first is to tension the squared string arrangement, and the second is the eyestay opening 93 and the retention bridge 91. Apply tension to the strap in between. The four fixed pulleys 84a-84d provide a low friction angle sliding point that allows the squared string to be tightened tightly during the process of pulling the sides of the shoe together. In a complementary manner, the fixation strap 81 engages the lateral line from the eyestay opening 93 in a manner that also draws the sides of the shoe together to provide a snug but comfortable fit for the wearer. It reaches the retention bridge 91 and is turned back to the fixed column assembly 88a.

  [0054] Next, an implementation that is very similar in many respects to the embodiment shown in FIG. 6 except that a fifth fixed pulley 84e is added in the middle of the tightening string first longitudinal portion 82a. Reference is made to FIG. 9 which provides a form. FIG. 9 is a plan view of a fourth preferred embodiment of the squared lace shoe closure system of the present invention having a single lateral puller acting on two sections of one side of the squared lace array, the system Is shown in an open-relaxed configuration. The effect of the arrangement of the fourth preferred embodiment is to double the tightening length of the squared string for a given lateral pull of the fixed strap.

  [0055] In addition to installing a fifth pulley (which may be the struts described above in connection with various other preferred embodiments above), a single connection so far for the fixation strap The points are modified in this fourth preferred embodiment to provide two connection points, one on each of the strap clasps 93a and 93b. The Y-shaped configuration for the fixation strap 92 in this case pulls the string twice, thus directing a double compression force with a given lateral movement of the fixation strap 92. Otherwise, the configuration of the securing strap 92 with the pull tab 97 and the hook opening array 95 remains essentially the same as the linear strap configuration described above.

  [0056] In the embodiment shown in FIG. 9, two elasticities are used to provide residual tension when the tensioning string is relaxed and to provide a surface over which the Y-shaped securing strap is pulled. It is desirable to place straps 75a and 75b across the tongue 22 between eyestays. Otherwise, the strap attachment method remains essentially the same. An alternative way of creating a Y-shaped strap configuration involves the loop of strap material forming the Y-strap arms 94a and 94b onto which the straight section of the fixed strap 92 is hooked. Various mechanisms for maintaining the Y-shaped configuration of the lateral puller securing strap 92 are envisioned.

  [0057] The embodiment shown in FIG. 9 is generally not constructed to allow user changes in the direction of lateral pull. For this reason, FIG. 9 discloses the addition of only one fixed post assembly 88 and only one new fixed pulley 84e. However, for those skilled in the art, if a sixth fixed pulley (not shown) and a second fixed post assembly (not shown) are added, the system will not be as shown in FIG. It will be appreciated that the orientation of the Y-shaped securing strap can be configured to be reversed to pull in the opposite direction. Certainly, the shoes may be manufactured with the orientation of the handle straps from the inside to the outside, or with some complexity, so that the user can select the direction of the lateral pull. May be.

  [0058] Next, a Y-shaped tensioning strap embodiment similar to that shown in FIG. 9 except that the tensioning string is divided into two separate closed loop string components or subassemblies. Reference is made to FIG. In order to accommodate two separate squared lace components, each shoe eyestay has two shoe center twos to serve as a corner guide post for each individual of two separate squared lace subassemblies. Heavy pulleys 84e and 84f are arranged. FIG. 10A is a plan view of a fifth preferred embodiment of the squared lace shoe closure system of the present invention having a single lateral puller acting on each side portion of two separate closed loop squared lace subassemblies. It is. FIG. 10A shows this fifth embodiment in an open-relaxed configuration. The effect of the fifth preferred embodiment arrangement is to further multiply the tightening length of the squared string component for a given lateral pull on the securing strap.

  [0059] The double squared string arrangement shown in FIG. 10A comprises two separate rectangular arrays for the squared string closure system 90, the two separate closed loop strings being the tightening string first. Forming a double squared string array having a first squared string component comprising a longitudinal portion 82a, a tightening strap central lateral portion 82b, a tightening strap second longitudinal portion 82c, and a tightening cord rear lateral portion 82d. ing. The second lower tightening string component includes a tightening string first longitudinal part 86a, a tightening string front lateral part 86b, a tightening string second longitudinal part 86c, and a tightening string central lateral part 86d. Although this fifth preferred embodiment provides two separate square laces, the function of the lace array is in the process of shrinking the lateral elements of the square lace components that serve to pull the sides of the shoe together. It is essentially the same as the function described above in relation to it. By tightening the longitudinal elements of the squared string component in the lateral direction to form slanted string elements, the longitudinal elements are stretched and the transverse elements are correspondingly contracted.

  [0060] The securing strap 92 shown in FIG. 10A includes a pull tab 97, an aperture array 95, and strap clips 93a and 93b. The securing strap 92 is designed to be secured to the lacing strap first longitudinal portions 82a and 86a or alternatively to the lacing strap second longitudinal portions 82 and 86c, depending on the direction of lateral tension that the user wishes to perform. ing. Thus, the tightening strap can be placed laterally so that the user can tighten the shoe across the shoe laterally from the outside of the shoe (the outer side of the shoe) to the inner side of the shoe or by reversing the process. A fixed strut assembly is disposed on each side of the shoe so that it can be directed outward (outside) from the inner side of the shoe. Tie guards 96a and 96b provide optional connection points on the tightening cord second longitudinal portions 82c and 86c, and instead strap straps 93a and 93c are secured thereon (fixed strut assembly 88a). It is also possible to achieve reversal of the lateral tightening direction (using 88b instead).

  [0061] The way of connecting the fixing strap 92 to the side of the shoe is provided by one of the fixing strut assemblies 88a and 88b, as before, to tighten the fixing strap 92 in the lateral direction and the second longitudinal portions 82c and 86c. If it is straddling over or in the reverse direction, it is started by pulling over the tightening string second longitudinal portions 82a and 86a. The manner in which the locking mechanism is utilized is essentially the same as that described in more detail above with reference to FIG.

  [0062] Tan string guide 89 and elastic bands 75a and 75b are again shown as dashed lines as an optional addition to the squared string closure system 90. In the open configuration shown in FIG. 10A, the elastic bands 75a and 75b are fixed straps 92 in a manner that retains some tension in the system that draws the sides of the shoe together even when the lace closure system is not tightened. It is shown that it is placed under the arm of. In FIG. 10A, a tongue strap guide 89 is also disclosed in a manner similar to that of the first preferred embodiment described above, with the shoe tongue 22 being pulled up by the residual tension of the tension strap rear lateral portion 82d. .

  [0063] Next, an alternative dual tension strap embodiment similar to that shown in FIG. 10A is provided, except that the Y-shaped tension strap is separated into two linear tension straps. Reference is made to FIG. 10B. The embodiment shown in FIG. 10B is suitable for use in connection with a shoe structure that includes an upper bump section and a lower bump section with separate side quarters of the shoe, the bump portion being It can be secured through separate closed loop lace components or subassemblies. Upper bump edges 87a and 87b indicate a dividing line between the upper bump section and the lower bump section. This shoe configuration is similar to that described in US Pat. No. 4,200,998. The upper bump is such that the upper bump edges 87a and 87b extend over the lower bump section (shown in FIG. 10B), or the upper bump section and the lower bump section uniformly contact at each edge. Or, finally, may be configured such that the lower bump section can extend over the upper bump portion (not shown).

  [0064] To accommodate two separate squared lace components in this alternative embodiment, the two shoe center double pulleys shown in FIG. 10A are replaced with a total of four single pulleys 84e-84h. It has been. In this manner, the two squared string components can function completely separate from each other, allowing each squared string component to be clamped in an independent manner. As before, FIG. 10B shows a fifth preferred embodiment of the squared lace shoe closure system of the present invention having double lateral pull straps acting on each side portion of separate closed loop squared lace subassemblies. It is a top view of an alternative structure. FIG. 10B shows this alternative structure for the fifth preferred embodiment in an open relaxed configuration. The effect of the arrangement in this alternative structure of the fifth preferred embodiment further multiplies the respective tightening lengths of the squared string components for a given lateral pull on an independent securing strap. That's it.

  [0065] The double squared string arrangement shown in FIG. 10B comprises two separate rectangular arrays for the squared string closure system 91, and the two separate closed loop strings 83a and 83b are double. A rectangular string array is formed, the first rectangular string component 83a is configured on the upper bump section with the same four sides as the rectangular string array, and the second square string component 83b is a lower bump. It consists of the same rectangular array on the section. Similar to the arrangement shown in FIG. 10A, this alternative structure to the fifth preferred embodiment provides two separate squared laces, the function of the lace array pulling the sides of the shoe together It is essentially the same function as described above in connection with the process of shrinking the transverse elements of the working square string component. By tightening the longitudinal elements of the squared string component in the transverse direction to form slanted string elements, the longitudinal elements are stretched and the transverse elements are correspondingly contracted.

  [0066] The fixation straps 94a and 94b shown in FIG. 10B include aperture arrays 95a and 95b and strap clips 93a and 93b. The securing straps 94a and 94b are instead constructed to be secured to the strap clip points 96a and 96b to provide an optional connection point on the tightening strap portion and instead secure the strap clips 93a and 93b thereto. In this way, reversal of the lateral tightening direction (using 88b and 88c instead of fixed post assemblies 88a and 88d) can also be achieved. Thus, the strap can be pulled laterally so that the user can tighten the shoe laterally across the shoe from the outside of the shoe (the outer side of the shoe) to the inside surface, or the user can reverse the process. A plurality of fixed strut assemblies 88a-88d are arranged as two on each side of the shoe so that the direction from the inner side of the shoe to the outside (outside) can be made. One possible implementation of the strap shown in FIG. 10B is to arrange one securing strap so that it can be tightened in one direction and a second securing strap so that it can be tightened in the opposite direction. It is. Being able to reverse the direction of the fixing strap by changing the clip position of the fixing strap to the tightening string allows these variations in the direction of the lateral tightening.

  [0067] A way to connect the fixation straps 94a and 94b to the side of the shoe is provided by one of the fixation post assemblies 88a-88d, as in FIG. 10A. This operation of connecting the fixation straps is initiated by pulling each fixation strap across the opposite portion of the side of the lateral tensioning strap, in which manner the fixation mechanism is described above with reference to FIG. Used in essentially the same way as described. In FIG. 10B, a tongue strap guide 89 is also disclosed in a manner similar to the first preferred embodiment described above, with the shoe tongue 22 being fastened up by the residual tension of the tension strap 83a.

  [0068] Next, the lateral fixation strap (s) similar to the embodiment shown in FIGS. 10A and 10B is replaced with a single strap that is redirected longitudinally for fixation. Reference is made to FIG. 11 which provides a tightening string arrangement. FIG. 11 provides a sixth preferred embodiment of the squared lace shoe closure system of the present invention having a single longitudinal puller acting on each lateral portion of two separate squared lace subassemblies. Yes. FIG. 11 shows this sixth embodiment in an open-relaxed configuration. The effect of the arrangement of the sixth preferred embodiment is to further multiply the tightening length of the squared string component for a given longitudinal pull on a single securing strap.

  [0069] Similar to FIGS. 10A and 10B, the squared array shown in FIG. 11 comprises two separate rectangular arrays for the squared string closure system 100, and the two separate closed loop strings are A double square having a first upper squared string component comprised of a tension string first longitudinal portion 102a, a tension string central lateral portion 102b, a tension string second longitudinal portion 102c, and a tension string rear lateral portion 102d. A chemical string array is formed. The second lower tightening string component includes a tightening string first longitudinal portion 106a, a tightening string front lateral portion 106b, a tightening strap second longitudinal portion 106c, and a tightening strap central lateral portion 106d. This sixth preferred embodiment provides two separate closed loop squared strings, as did the fifth preferred embodiment described above, but the function of the string array is shown in FIG. And somewhat different from the embodiment shown in FIG. 10B. The upper and lower lateral lace portions continue to pull the sides of the shoe together by being shrunk in a closing process, while the central lateral portion of the lace component will be tightened diagonally in the longitudinal direction. The central double pulleys 104e and 104f are pulled together, and at the same time, the longitudinal portion of the rectangular string component is pulled to further tighten and contract the upper and lower lateral portions. This arrangement provides yet another way in which the squared string is tightened together in the process of closing the upper eyestay areas to provide a snug but yet comfortable fit.

  The fixed strap 108 shown in FIG. 11 includes a strap pull tab 112 and a strap clasp 110. However, the strap fixing point in this case is in the upper slide collar 114 disposed on the tightening string rear side portion 102d. The manner in which the fixation strap 108 connects to and is fixed to the slide collar 114 is described in more detail below with reference to FIG.

  [0071] The sixth embodiment shown in FIG. 11 also benefits from the use of residual tension elastic bands 75a and 75b, each disposed in connection with one of the two rectangularized string components. . However, the previous tongue string guide is divided into two tongue string guides 115a and 115b arranged on both sides of the upper slide collar 114 in the sixth embodiment. Accordingly, the string guides 115a and 115b serve both the purpose of maintaining the position of the tongue 22 below the tightening string assembly and the function of maintaining the slide collar 114 in the center position on the string.

  [0072] FIG. 12 is a plan view of a seventh preferred embodiment of the squared lace shoe closure system of the present invention, with the direction reversed after first being directed down the shoe in the longitudinal direction; A structure is shown that achieves a single long puller that climbs a shoe while tightening a plurality of strings in a double closed loop squared string array together, and the system is shown in an open-relaxed configuration. The basic structure of this seventh preferred embodiment is very similar to that of the sixth preferred embodiment described above in connection with FIG. 11, with the lower slide collar 128 on the tightening cord front lateral portion 106b. It involves the addition and use of an elongated strap 120 that is positioned in an inverted orientation on the tensioning strap central lateral portions 102b and 106d. In the configuration shown in FIG. 12, the clasp 122 passes through the securing strap 120 on the central lace portion, which extends downward in the longitudinal direction toward the shoe toe and under the lower slide collar 128. And then being redirected around the lower slide collar 128 and pulled upward to allow engagement with the upper slide collar 114 in a manner similar to that shown in FIG. Position with. The process of tightening and closing the lace system 100 shown in FIG. 12 is an additional way of increasing the tightening length of the lateral lace portion so that the overall force of pulling the upper sides across the tongue is increased. It is. In the arrangement shown, the strap portions 106d, 106b, and 102b are tightened together and the group is pulled up to a connection point with the upper slide collar 114 on the strap portion 102d.

  [0073] Finally, refer to FIGS. 13 and 14 for detailed partial cross-sectional views of the pull strap attachment structure for the sixth and seventh preferred embodiments, respectively. FIG. 13 shows an arrangement for the pull strap structure shown in FIG. 11, whereby the fixed strap 108 is located on the connection points to the tightening strap central lateral portions 102b and 106d and on the tightening strap rear lateral portion 102d. It extends between fixed positions at the upper sliding collar 114 that is secured. A strap clasp 110 disposed on the securing strap 108 allows the clasp and attached strap to be securely but removably secured to the tensioning strap central lateral portions 102b and 106d as shown. It is configured.

  [0074] In the perspective of FIG. 13, the tongue 22 is shown with an elastic band 75a placed loosely on the tongue. The fixed strap 108 ending with the strap pull tab 112 is configured with a hook channel array 116 that provides a plurality of hook-like channels sized to engage around the cylindrical structure of the upper slide collar 114. By pulling the securing strap 108 upward (longitudinal), the user can selectively position the upper slide collar 114 into one of the hook channels in the hook channel array 116 to secure the strap in place. Can do. During the process, the square lace closure system is tightened together to achieve close fit to the shoe as described above.

  [0075] FIG. 14 provides a detailed partial cross-sectional view of the pull strap attachment structure of the seventh preferred embodiment shown generally in FIG. In this embodiment, the elongated securing strap 120 includes a similar strap clasp 122 that secures the end of the strap to the tightening strap central lateral portions 102b and 106d, also preferably from below in this embodiment. The fixing strap 120 is then fed down around the lower slide collar 128 disposed on the front side portion 106b of the tightening strap down the shoe, and then the center line of the shoe is folded back upward in the longitudinal direction. It extends to the point of attachment to the upper slide collar 114 disposed on the lateral portion 102d. The opposite end of the fixed strap 120 that terminates in the strap pull tab 124 has a hook channel array 126 that provides a plurality of hook-like channels sized to engage around the cylindrical structure of the upper slide collar 114. It is prepared for. Again, by pulling the securing strap 120 upward (longitudinal), the user can selectively move the upper slide collar 114 into one of the hook channels in the hook channel array 126 to secure the strap in place. Can be positioned. In the view of FIG. 14, the tongue 22 is shown with elastic bands 75a and 75b placed loosely on the upper surface thereof. The block arrows in FIG. 14 show how the entire array of transverse lace portions is tightened together by the straps to achieve compression of the side of the shoe for close fitting as described above.

  [0076] As will be appreciated by those skilled in the art, the preferred embodiments of the invention described are generally presented in terms of a single pulling action that is accomplished from or on the inside surface of a shoe. However, all such embodiments can also be easily accomplished from the outside (outside) or outside (outside) of the shoe. In addition, although a number of embodiments have been described that allow for a user-selected pulling direction, each of the embodiments may be implemented with such user-selected functionality. You may implement without preparing. In any event, there is a balance between user selectivity and a corresponding increase in the complexity of the squared string structure that would occur in the case of a mirrored fixation assembly.

  [0077] While various embodiments of the present invention have been described in relation to a shoe incorporating a tongue disposed between parallel and opposite eyestays, as will be appreciated by those skilled in the art The present invention may be implemented in a shoe that does not have a specific tongue structure, such as a shoe configuration having side surfaces that overlap at the upper center line of the shoe, or in a shoe that does not have eyestays parallel and opposite to each other. It may be implemented, or it may be implemented in shoes where the front opening of the shoe is not centered on the top of the foot. As long as the corner or side point structures of the various embodiments are located on opposite sides of the shoe, the shoe structure between them only needs to be compressible when the sides of the assembly are pulled together. Good. Those skilled in the art will recognize additional modifications of the squared string open and closed loop structure and the specific arrangement of corner and side point mechanisms that still fall within the spirit and scope of the squared string single pull functionality of the present invention. Will be recalled.
