  • Retention elements can be elastic or inelastic or any suitable combination of materials may be used. They are generally elongate elements in the form of bands, straps, cords, or cables.
  • retention element 28 may have a forward end portion 29 in the form of a non-stretch band of material that is fixed at one end at position 30 forward of heel cup 10, that wraps around the heel cup, and that has its other end similarly fixed on the other side of the shoe at a position forward of the heel cup.
  • a retention element may be a single unit or multiple units coupled together to form a continuous line of tension from an anchor point on the shoe to the heel cup.
  • retention elements may be based on elastic materials that provide comfort during use or openability of the heel cup. Elastic materials have the advantage of providing positive tension on the heel of a wearer under all conditions. If desired, inelastic materials can also be used to provide positive tension by ratcheting mechanisms, buckle mechanisms, cable tension mechanisms, etc.
  • Retention element 28 tensions heel cup 10 with its forward anchoring points when placed over the heel cup at least when a foot is placed in the shoe, and thereby prevents heel cup 10 from folding backwards.
  • the retention element can also be made tensionable so that positive tension is placed on the wearer's heel during use.
  • the retention element is releasable in a manner that allows the heel cup to open.
  • retention element 28 in the form of a band, is upwardly/downwardly floatable or pivotable over the heel cup so that the heel cup can move from a closed position to an open position.

For example, in the embodiments shown, when a retention element is positioned in a first zone at the upper of the heel cup, the heel cup is held in the closed position. Moving downward from this first zone, the retention element crosses a point at which the retention element enters a second zone. When the retention element is positioned in the second zone, the heel cup may fold backward.
  • the second zone may start at the apex of a convex shaped heel cup and extends downward and below the hinge of the heel cup. Unless the user forces the retention element over the apex, the apex keeps the retention element from moving across one zone to another.
  • a forward anchor point of the retention element is releasable from the shoe so that the heel cup opens.
  • the retention element can be made in two or more sections that releasably join together at points along the length of the retention element.
  • the retention system of the shoe may further include a retention lock system that interacts with one or more retention elements to facilitate closing of the heel cup and tensioning of the retention elements.
  • the functions of the retention lock system may be accomplished by, for example, a catch mechanism interacting with a receiver or apex of the heel cup, a tension tuner interacting with one or more retention elements, a tab assisting in moving and locking the catch mechanism, and/or a lock disposed on the heel cup that engages the one or more retention elements so that tension is maintained.
  • retention element 28 is coupled to a catch mechanism 38 that assists in holding heel cup 10 in place, for example a strap, which interacts with a receiver, such as a groove, hook, knob, so that the heel cup stays in the closed position against the wearer's heel.
  • catch mechanism 38 is positioned at the heel section of the shoe and holds the two retention elements 28.
  • catch mechanism 28 may hold the retention elements symmetrically relative to both sides of the shoe.
  • catch mechanism 28 may engage a single retention element 28 that runs from one side of the shoe to the other side of the shoe.

In the first position, mechanism 38 is positioned off the heel cup, below the hinge, as shown in FIG. 1. In the second position, catch mechanism 38 is positioned on heel cup 10, as shown in FIG. 6. Catch mechanism 38 acts as a lock that engages retention element 28 so that heel cup 10 is maintained in the open or closed position. Catch mechanism 38 engages a receiver 40 (open) and/or 42 (closed) to lock the retention element 28 and heel cup 10 in the opened or the closed position.
  • the catch mechanism and receiver may be formed as a pair of complementary engageable male and female parts. For example, as may be seen in FIGS.
  • receiver 40 may be formed by a protrusion molded into the midsole of sole unit 4, below the hinge of the heel cup, and wherein the protrusion engages and locks catch mechanism 38.

  • the hingeable element may be formed as a distinct piece of one or more materials, at one end connected to a lower portion 20 of heel cup 10 and at the other end connected to a rear end portion 22 of the shoe, which may be part of shoe upper 6 or sole unit 4.
  • the heel cup may be connected to the shoe at any position at the platform portion of the shoe that allows the heel cup to move from an open position to a closed position.
  • the heel cup and hingeable element may be connected to the foot platform portion of the sole unit or an extension thereof.
  • the heel cup may be connected to an extension of the forefoot section or a suitable portion of the shoe upper.
  • the foot-entry opening may be formed by a cut in the shoe upper.
  • the cut may be made starting at any point along the top edge of the shoe upper and follow, for example, a vertical or angled line towards the sole of the shoe.
  • the cut in the shoe upper may slope down towards the heel section of the shoe to create an enlarged opening for foot-entry, as shown in the Figures.
  • the forefoot section of the shoe upper may be formed by a cut sloping down towards the hingeable element connecting the shoe upper and the heel cup.
  • the downward sloping shoe upper may have any shape suitable to facilitate foot entry and to accommodate a heel cup.
  • the foot-entry opening may be formed as a cut running from the upper of a regular athletic shoe, for example, by cutting the shoe upper approximately along line A extending from a tongue and lace area 15 from forefoot section 8 towards sole 4 and further sloping down towards heel area 9 of shoe 2.
  • Line A is anatomically positioned below the ankle of the foot and generally runs from the foot upper towards the heel of the foot.
  • the cut-out shown enlarges the foot-entry opening, allowing for easier and farther foot insertion.
  • FIG. 9 shows an area 13, marked with dotted lines, where extra material is removed from shoe upper 6.
  • Area 13 has a general triangular-like shape defined by interconnecting points BCD.
  • Side B-D of the triangular shape is formed by cutting shoe upper 6 approximately along line A starting at point B, as described above.
  • a second side, side B-C is formed starting at the edge of the shoe upper at line A, i.e., at point B, and following the edge of shoe upper 6 for a length of about 2 cm, for example, towards heel area 9 up to point C.
  • a general vertical cut is made ending approximately in point D at the intersection with line A.
  • Point D is located at a height that is about half of the height of shoe upper 6, i.e., shown in FIG. 9 along a line E that is located about 2 cm above sole 4 of shoe 2.
  • a fabric material such as a stretchable mesh, may span the area between the downward sloping of the shoe upper and the heel cup, such as area 13.
  • the opening between the shoe upper and heel cup, such as area 13 may be covered by one or more of the retention elements described above.
  • a retention element 128 may have a shape 113 corresponding to about the cut-out area 13 so that the combination of shoe upper, retention element, and heel cup create the look of a complete upper.
  • FIG. 11 shows another example of a retention element 128 having a width 129 allowing for the retention element to cover cut-out area 13 to create the look of a complete upper.
  • the shoe upper may have any suitable shape that together with the heel cup completes an upper enclosure around the foot, for example, a shoe upper formed of one or more straps and mesh surroundings.
  • the inventive subject matter further contemplates a method for making and using the heel-entry athletic shoe described above.
  • the above described heel-entry athletic shoe may be made by mounting or otherwise integrating a shoe upper on a sole unit.
  • the shoe upper generally has a forefoot section and a heel cup.
  • the heel cup may be hingeably coupled to the sole unit of the shoe.
  • the heel cup may be moveable from an open position, for placement of a foot into the forefoot section of the shoe upper for enclosing a forward portion of the foot, to a closed position, for completing an upper enclosure around the foot.
  • the shoe is further provided with a retention system for tensioning the heel cup against the heel portion of the foot and maintaining the upper enclosure around the foot.
  • Such a retention system may include one or more retention elements, each having one end portion connected to a position on the shoe forward of the heel cup and a portion that wraps around the heel cup so that the heel cup is maintained in the closed position during use.

Abstract

L’invention concerne une chaussure à entrée par le talon, possédant un emboîtage du talon couplé articulé ou coulissant à l’unité semelle de la chaussure, et l’emboîtage de talon pouvant passer d’une position ouverte, servant au placement du pied dans la partie d’avant-pied du dessus de la chaussure et, ainsi, à abriter la partie avant du pied, à une position fermée permettant d’obtenir une enceinte supérieure autour du pied. Un système de retenue retient par tension l’emboîtage du talon contre la partie talon du pied, et maintient l’enceinte supérieure autour du pied. Le système de retenue peut comprendre un élément de retenue possédant une extrémité reliée à une position avant de l’emboîtage de talon et une partie enroulée autour dudit emboîtage de talon. Le système de retenue peut flotter, au-dessus de l’emboîtage de talon, entre une première position permettant à l’emboîtage de talon de passer en position ouverte par articulation ou coulissement, et une seconde position de maintien de l’emboîtage de talon en position fermée.
