Definitions

  • the present invention relates, in general terms, to improvements in articles of apparel. More particularly, but not exclusively, the present invention relates to an improved article of footwear for use in the playing of, and for participation in, sporting and the like recreations. In actual fact, however, in real terms the improved article of footwear in accordance with the present invention lends itself readily to use in any context, even normal day-to-day usage.
  • the improved article of footwear in accordance with the present invention is especially suitable or designed for usage by people participating in the playing of games such as football, be it Australian Rules Football, soccer, rugby (either League or Union) or whatever. Indeed, throughout the ensuing description reference will be made to a particularly preferred embodiment of the invention, intended for such usage. It should be realised, however, that the article of footwear in accordance with the present invention lends itself to usage in any context wherein some form of support is required for the ankle of the wearer, in order to protect that ankle against the rigours and stresses associated with the relevant pastime. Under no circumstances, therefore, should the arrangement in accordance with the present invention be considered to be limited to any specific embodiment or context of usage hereinafter described in detail.
  • a means, associated with a shoe (sports shoe) of any given type which acts to either prevent the incidence or onset of ankle roll, or alternatively protect a once-damaged ankle against a recurrence of such an injury.
  • a shoe sports shoe
  • past experience has revealed that, with sports shoes of the type commonly and currently in use, there almost invariably exists a tendency for the wearer, under certain conditions of use, to what is termed "roll" the ankle, giving rise to possible ligament damage, breakage of bones, etc.
  • ankle roll Whilst the prevention of what is termed ankle roll need not always be an athlete's immediate priority, from time to time the prevention of such ankle roll, or perhaps more often the prevention of recurrence thereof, can become a major objective of most sports participants. In a practical sense ankle roll not only gives rise to possible ligament damage and other injuries, but ultimately can affect the athlete's stability, state of mind and overall performance.
  • a first variation from the aforementioned standard sports shoe involved the usage of what might be termed high-cut shoes or boots, being an arrangement wherein the upper of the shoe in fact extended up and over, and indeed surrounded, the ankle of the wearer. Whilst such a configuration was found to afford a degree of additional support for the ankle, athletes/wearers have generally considered such shoes to be overly bulky and, in some instances, to in fact inhibit proper flexing of the foot, thereby imposing an unwanted restriction on the wearer.
  • a third alternative previously employed involves the use of what are termed ankle braces, adapted to be inserted into an existing sports shoe or the like. Such braces have been found, however, to be unduly weighty. Furthermore, such braces have been found by their very nature to be designed to be multi-functional and therefore not to cater for the differing requirements of different sports people.
  • the present invention therefore seeks to overcome the problems and disadvantages associated with the prior art by providing an article of footwear which affords improved support for the ankle of the wearer, yet in no way inhibits overall flexibility of the foot of such wearer.
  • the present arrangement provides the wearer with the equivalent of the degree of ankle support and protection afforded by the prior-art ankle braces, preventing ankle roll or over- extension of the ligaments of the wearer (in sideways movement), without in any way restricting the flexing of the foot in a straight line.
  • an ankle support assembly adapted in use to be co-operable with a shoe or the like article of footwear, said ankle support assembly including means adapted, in use, to embrace the ankle of the user, or disposed around the ankle of the user, means for fixing said embracing means in position relative to the ankle of the user, and means for attaching said ankle support assembly to said shoe.
  • the ankle support assembly will be attached to the upper of the shoe. In real terms, however the assembly may be attached to any part of the shoe, as for example, the sole.

  • a preferred arrangement in accordance with the present invention involves a sports shoe, preferably in the form of a football boot or the like, including an upper (1 ) and a sole (2), adapted to be interconnected in any known way, as for example by stitching, glueing or the like.
  • the sole (2) furthermore includes means allowing for attachment thereto or association therewith, again in any known way, of a plurality of ground-engaging members of the like, as for example studs of the type commonly in use.
  • the studs (3) may be removably connectable to the sole (2) and its associated upper (1 ), but in an alternative embodiment the sole (2) and associated studs (3) may be moulded or formed integrally in a single operation.
  • the arrangement in accordance with the present invention includes a means adapted to be associated with the sports shoe so as to be, in use, disposed around and whereby to embrace the ankle of the wearer.
  • Such means can be adapted to be either permanently attached, or removably attached, to the upper (1 ) of the sports shoe.
  • the potential for damaging ankle-roll can vary, from there being an extremely high probability of such ankle roll to a situation wherein the possibility thereof is minimal, if not actually non-existent.
  • an ankle support assembly in accordance with the present invention is adapted to be releasably attachable thereto.
  • an ankle support assembly in accordance with the present invention may be manufactured and marketed separately from the sports shoe itself, giving the purchaser the option of either going without such assembly or utilising the assembly only when and as needed.
  • the anklet 4 is of such a shape as to not extend, in use, all the way around the ankle of the wearer.
  • the gap or discontinuity (5) provided, as shown more clearly in Fig. 2 assists in affording increased flexibility to the overall configuration. This is in marked contrast to standard sports shoes which, if they have any ankle protection at all, involve an arrangement which serves to extend around the entire foot of the wearer, rather than having sections missing as shown in Fig. 2.
  • the cut-away or gap (5) does not cover, and in fact exposes, the achilles tendon area of the foot of the wearer.
  • yet another portion or section of the foot of the wearer of the sports shoe, more particularly on the top of the foot where it joins the leg, is also not covered or enclosed by or with material.
  • excess material in such a location only serves to get in the way when the foot flexes, restricting how far the foot and ankle can bend.
  • the injury prevention capabilities of the arrangement in accordance with the present invention emanate from the fact that the anklet (4) can remain in substantially the same position on the leg of the wearer as the achilles tendon stretches. This means that the anklet (4) can act as a stable base. It has also been found that the shoe itself will act as a stable base.
  • a standard sports shoe is designed to attach well to the foot and not to twist. As illustrated in the drawings there is a cross-over of straps (7), this giving rise to a situation wherein the strap (7) from one side can be used to "lock in” the strap (7) from the other side, forming a "cross” at the front of the foot as illustrated more clearly, for example, in Figs. 1 and 3.
  • the main ligaments to protect are what might be termed the lateral ligamentous complex on the outside of the foot.
  • the connecting apparatus between anklet (4) and shoe upper (1 ) on the lateral side of the arrangement in accordance with the present invention has been found to support these ligaments or ligamentous complex and to limit the extent to which they can be stretched.
  • the shoe upper (1 ) is effectively connected to the anklet (4) on each side by two means. Firstly it is itself attached to the anklet (4) on each side of the ankle of the wearer by means of sections (6). Secondly it is adapted to be attached to the opposed or opposite sides of the ankle by means of a connectable strap (7).
  • each strap (7) will be made of a material such as Velcro (Trade Mark) adapted, in use, to be affixed to or co-operate with an equivalent material provided on the anklet (4).
  • Velcro Trade Mark
  • an especially preferred embodiment of an ankle support assembly (10) in accordance with the present invention includes a shin band portion (1 1 ), adapted in use to go around the front of the shin of the wearer, an achilles band portion (12) which is adapted, in use, to go around the ankle of the wearer and extend around the achilles tendon, and a knuckle cover portion (13) adapted, in use, to extend over and embrace the ankle knuckle joint, said knuckle cover portion (13) having associated therewith means (14) allowing for attachment, fixedly or releasably, to a sports shoe or the like, and more particularly to the upper (1 ) thereof.
  • the overall ankle support assembly (10) will be of a unitary construction, made up of one and the same material in a single operation.
  • the shin band portion (1 1 ), achilles band portion (12) and knuckle cover portion (13) can be formed separately and interconnected in any known manner.
  • the overall ankle support assembly (10) will be constructed of a suitable non- stretching material.
  • a composite or layer of materials may be employed in the construction of the overall assembly (10) and/or the individual components or portions (1 1 ), (12) and (13) thereof.
  • the overall assembly (10) may be attached, in any known manner, to a shoe upper (1 ) at at least one side, and preferably two sides, thereof.
  • the assembly (10) may be releasably connectable to a shoe upper (1 ), as for example through the co-operation of Velcro (Trade Mark) strips (not shown) appropriately disposed externally on the shoe upper (1 ) and internally on the support assembly, or more correctly the knuckle cover portion ( 1 3) thereof.
  • Velcro Trade Mark
  • Such an arrangement will allow for ready removal of the support assembly (10) from the shoe when not desired, or alternatively ready attachment of the support assembly (10) to the shoe as and when desired, thereby affording a sports shoe in accordance with the present invention greater flexibility in use.
  • an ankle support assembly (10) in accordance with the present invention may be fixedly and non-removably connected to the shoe, preferably to the shoe upper (1 ) .
  • One means of achieving such fixed and non-removable connection may be by stitching, a practice commonly employed in the shoe trade.
  • the ankle support assembly (10) may be affixed in position at the appropriate place on the shoe upper (1 ) by means of a suitable adhesive.
  • the support assembly (14) and associated shoe upper (1 ) may be constructed/constituted by an integral member adapted to be appropriately affixed (again in any known means) to a shoe sole (2) .
  • the shoe and associated ankle support assembly (10) will be constructed of one and the same material, as for example leather.
  • the arrangement in accordance with the present invention is responsible for enhanced improvement in the degree of ankle protection afforded the wearer. In both psychological and physiological terms, this gives the wearer more confidence that his (her) ankles will withstand any undue stresses imparted thereto, whilst at the same time not losing any flexibility of movement. A significant improvement in performance can therefor be expected.
  • the ankle support assembly in accordance with the present invention functions by reason of the fact that it limits the distance - as measured on the skin over the ankle knuckle of the wearer - between the sole of the foot and the leg. In that regard it should be understood that, when a person happens to "roll" an ankle, the aforementioned distance increases.
  • ankle ligaments function to limit the extent of such increase but, in doing so, such ligaments can be subjected to or placed under extreme pressure, with the result that the ligaments can often either break/rupture or tear.
  • the ankle support assembly in accordance with the present invention acts to restrict the extent of stretching of the ankle ligaments, with the anklet or ankle support assembly absorbing the forces imparted to the ankle during the relevant movement, rather than the ligaments.
  • the ankle support assembly in accordance with the present invention surrounds and embraces either the whole of or a significant part of the circumference of the ankle of the wearer above the ankle knuckle.
  • the ankle support assembly remains in, to all intents and purposes, the same relative position on the leg of the wearer as the achilles tendon is stretched during the relevant movement, thus providing or acting as a stable base.
  • the ankle support assembly act to support the ankle ligaments on the outside of the foot and to set a mathematically definable limit on the extent to which such ligaments may be stretched. By setting such a limit the likelihood of damage to the ankle is significantly reduced, if not removed altogether.
  • the ankle support assembly in accordance with the present invention is so constructed that it does to no great extent restrict flexing of the foot of the wearer in a straight line, nor restrict the power to be applied in the actions of running, jogging, jumping, or whatever.
  • the ankle support assembly in accordance with the present invention by its very nature, is readily and easily adjustable, thereby allowing it to be tailored to an individual's physique and/or their needs at any particular point in time, or for participation in any particular sport, pastime or activity.
  • FIGs. 7 to 1 1 inclusive there is illustrated therein another preferred means for releasably attaching an ankle support assembly (10) in accordance with the present invention to a shoe, in particular a shoe upper (1 ).
  • Such relies on inter-action between mating and substantially complementary shaped male and female members (20) and (30) adapted to be affixed (releasably or otherwise) to respective ones of the shoe upper (1 ) and the support assembly (10).
  • the male member (20) is attached to the shoe upper (1 ).
  • the female member (30) may then be attached - releasably in any known manner or permanently as for example by stitching or glueing - to the portion (13) of the support assembly (10).
  • the male member (20) takes the form of a length of suitable material, as for example a plastics material, having the topmost free-end portion thereof of an arrow-head or the like shape (21 ), whilst the female member (30) is in the form of a plastics material component having a slot or aperture (31 ) therein of a shape complementary to the arrow-head portion (21 ) of the male member (20).
  • the male member (20) has a v-shaped cut- out (22) immediately below the bottom edge of the arrow-head portion (21 ).
  • the female member (30), as shown in Figs. 8 and 10, may include a length of hard plastics material almost exactly equal to the length of the male member (20), thickened along the whole of its length at the bottom as at (32).
  • a hollow could be cut out in the shape of an arrow-head fractionally larger than the arrow-head shape of the male member (20) and the entire length at the bottom edge could be cut, except for a narrow neck portion (33) at the forward end thereof.
  • the embodiment as illustrated would then be operated by sliding the hollowed-out rear end of the female portion (30) on to the forward end of the male portion (20) (the v-shaped cut-out would allow this to be done easily) and then sliding them together along their whole length until they are completely matched.
  • the male and female portions (20) and (30) would thus be locked together, and the neck at the forward end of the female portion (30) would prevent the two parts from separating under pressure.
  • the slide-on components need to be made of a material which is tough enough to withstand the pressures applied during turning by heavy large wearers. There are many tough, relatively hard plastics suitable for this purpose. Other appropriate materials could also be used.
  • the part of the slide-on device that is connected to the shoe should preferably be as small as possible so as not to interfere with the aesthetics or function of the shoe. It should be understood that, in the preceding paragraphs, merely one preferred means of removably securing the ankle support assembly to a shoe is described. In a practical sense, however, a variety of different methods and means present themselves, including inter-acting sliding, gripping, screw-in, click-on or together, adhering, etc., joining devices.
  • the ankle bands - the shin and achilles band portions (1 1 ) and (12) - when joined have non-stretching material in the shape of the wrap of the skin around the leg in the area above the ankle knuckle (at the thickness of the ankle bands). This can be done in a variety of ways with various lengths of band portions and various overlaps.
  • the ankle bands are attached to the knuckle cover portion (13) at a distance from the edge of the plane of the sole which is less than the distance from the ankle band to the edge of the sole plane when the ankle is "rolled” minus the stretch due to any elasticity in the anklet and the shoe and also minus the change in distance from the medial side of the anklet to the edge of the sole due to the compression of the footwear components and body parts under the pressure of rolling of the ankle.
  • the knuckle cover portion (13) preferably is joined to the ankle bands and shoe so that it is positioned to cover the ankle knuckle when the ankle is rolled and when the leg is at angles in the range of, preferably, from 10 to 25 degrees to the normal to the sole plane.
  • the knuckle cover portion (13) is of a length such that, when the ankle is rolled, the knuckle cover portion (13) becomes, and remains, tense or extended or stretched down a line roughly parallel to the line of the leg.
  • the achieving of the coverage of the knuckle when the ankle is rolled can be done by the knuckle cover portion (13) being sufficiently wide at the knuckle area so that the knuckle is covered at all positions of the leg relative to the foot during a running action.
  • it can be achieved by a moving knuckle cover portion that moves when the leg moves and maintains its cover of the knuckle.
  • Such mechanisms can be joined at the top, bottom or middle of the knuckle cover portion and can slide, pivot or rotate.
  • the knuckle cover portion (13) is non- stretching but bendable/flexible so that it can flex when necessary with any running movement.
  • the ankle support assembly is functionally only attached on one side of the shoe via the knuckle cover means which, preferably, is adapted to extend over the lateral (outer) side of the ankle itself.
  • the knuckle cover means which, preferably, is adapted to extend over the lateral (outer) side of the ankle itself.
  • no "non-stretching" (as hereinafter defined) type material connected between the shoe itself and the overall ankle support assembly at either the front or back of the ankle.
  • the other, internal or medial side may - if desired - be anchored with a non-stretch type material or, in yet a further alternative, the overall assembly may be attached to the shoe at at least one point with a suitable "stretch" type material.
  • the ankle support assembly is detachable, with the structure being such that the knuckle cover portion is attached (located) in effect below the level of the ankle of the wearer.
  • "Non-stretching" type material of the type referred to earlier, has an elasticity equal to or less than leather.
  • the elasticity of a component is intended to mean the resultant elasticity of all materials together as employed in the active part of that component.
