Abstract

Embodiments of the present invention relate to footwear. The footwear may comprise a sole for supporting a foot and vamp means for extending from the sole. A heel restraint may extend from either side of the vamp means. The heel restraint may comprise biasing means for biasing the heel restraint to extend around the upper heel of the foot so that the foot is restrained from slipping from the footwear. The heel restraint may be able to be moved from the upper heel and toward the sole so that the foot can be slipped from the footwear. The footwear of the present invention, in many embodiments, is less prone to cause discomfort than other known footwear, owing to the fact that the heel restraint extends from the vamp means.

Description

    BACKGROUND
  • The present invention generally relates to footwear.
  • The reference to any prior art in this specification is not, and should not be taken as an acknowledgement or any form of suggestion that the prior art forms part of the common general knowledge.
  • Footwear is widely used for protecting feet. Footwear comes in a variety of different forms including, for example, shoes, boots and slippers.
  • The applicant has perceived a need for footwear which can restrain the foot when in use, yet can enable the foot to be either more readily inserted into or slipped from the footwear without using hands or hand-operated tools.
  • FIG. 1 of DE 196 11 797 discloses such a shoe including a sole for supporting a foot, and a vamp for covering the instep of the foot to hold the shoe onto the foot. A heel restraint extends from either side of the sole and around the upper heel of the foot so that the foot is restrained from slipping rearward from the shoe. However, in practice, the shoe is uncomfortable to wear and the heel restraint may cause blistering about the upper heel.
  • It is an object of the present invention to provide alternative footwear to that of FIG. 1 of DE 196 11 797.
  • SUMMARY
  • According to one embodiment of the present invention, there is provided footwear comprising:
  • a sole for supporting a foot;
  • vamp means for extending from the sole; and
  • a heel restraint for extending from either side of the vamp means, the heel restraint comprising biasing means for biasing the heel restraint to extend around the upper heel of the foot so that the foot is restrained from slipping from the footwear, the heel restraint configured to be moved from the upper heel and toward the sole so that the foot can be slipped from the footwear;
  • wherein the heel restraint comprises a heel strap and the biasing means is integrally formed with the heel strap.
  • The heel restraint extends from the vamp means which is elevated with respect to the sole. Accordingly, the free end of the heel restraint can more freely move when the foot moves within the footwear during walking and is less prone to cause discomfort to the heel, than if the heel restraint otherwise extended from the sole thereby increasing the acute angle between the sole and the heel restraint. Furthermore when steps are taken, the heel restraint applies less pressure to the heel, than if the heel restraint otherwise extends from the sole.
  • Preferably, the heel restraint is configured to pivot proximal to the vamp means. The user can readily pivot the heel restraint from the upper heel and toward the sole so that the foot can be slipped from the footwear.
  • Preferably, the biasing means biases the heel restraint to extend around the top of the heel. Preferably, the heel restraint can lock the foot within the footwear.
  • The heel restraint may extend from the vamp means such that a plane of the heel restraint approaches an orthogonal relationship with a tangential plane of the upper heel. The heel restraint may extend from the vamp means and contact the heel to form a comfortable fit.
  • The heel restraint may further comprise a stiffener for stiffening the heel strap. The heel strap may be mounted directly to the vamp means. The biasing means may comprise a pair of neck portions on either side of the heel strap about which the heel strap can pivot.
  • The heel restraint may be substantially resistant to lateral bending when it is moved downwards from the upper heel and toward the sole. Preferably, the heel restraint can be rotated downwards from the upper heel and toward the sole. The heel restraint may substantially maintain its shape when it is moved along the heel and toward the sole.
  • In one embodiment, the vamp means comprises a single vamp extending from either side of the sole and for retaining the foot between the sole and the vamp. The vamp may be made from leather, fabric or plastic.
  • In another embodiment, the vamp means comprises two separated instep restraints each extending from either side of the sole. A first one of the instep restraints may be located distal from the toes of the foot and comprise instep biasing means for biasing the first instep restraint to extend around the upper instep of the foot.
  • The first instep restraint may comprise a first instep strap. The vamp means may further comprise a pair of anchor tabs extending from the sole and to which the heel and first instep restraints are pivotally anchored. The instep biasing means may comprise at least one torsional spring located between the first instep strap and the anchor tabs. The instep biasing means may comprise a pair of torsional springs fast with respective anchor tabs. Alternatively, the first instep strap, instep biasing means and anchor tabs may be integrally formed.
  • A second one of the instep restraints may be located proximal to the toes of the foot and comprise a second instep strap extending from either side of the sole.
  • The footwear may further comprise a waterproof heel cover that can extend between the heel restraint and the sole.
  • The footwear may comprise any one of the following group: low shoes, shoe, slipper, sandal, mule, slide, scuff, backless sandal, slip-on, athletic shoe or similar.
  • The footwear may or may not comprise a tongue.
  • According to another embodiment of the present invention, there is provided footwear comprising:
  • a sole for supporting a foot;
  • an upper for extending from the sole; and
  • a foot restraint for extending from the upper, the foot restraint comprising a biasing arrangement for biasing the foot restraint to extend behind the upper rear portion of the foot so that the foot is restrained from slipping rearward from the footwear, the foot restraint configured to be moved toward the sole so that the foot can be slipped from the footwear;
  • wherein the foot restraint comprises a foot strap and the biasing arrangement is integrally formed with the foot strap.

  • DETAILED DESCRIPTION OF EMBODIMENTS
  • According to a first embodiment of the present invention, there is provided a sandal 2 as shown in FIGS. 1 and 2. The sandal 2 includes a rubber sole 4 for supporting a foot 6, and a leather vamp 8 extending from either side of the sole 4. The vamp 8 retains the foot 6 between the sole 4 and the vamp 8 in use. The sandal 2 further includes a pivotal heel restraint 10 which extends from either side of the vamp 8 and around the upper heel 12 of the foot 6 so that the foot 6 is restrained from slipping rearward from the footwear 2 and is effectively locked into the footwear 2. Referring to FIG. 1, the heel restraint 10 can be pivoted downward from the upper heel 12 and toward the sole 4 (see dashed lines) so that a small gap 14 may be formed between the heel restraint 10 and the heel 12. Accordingly, the foot 6 can then more readily slip or be slipped from the footwear 2 without significant impediment.
  • The heel restraint 10 includes biasing means in the form of a pair of discrete torsional springs 16 a, 16 b mounted on either side of the vamp 8 so that they are co-incident with a pivot axis 18 of the heel restraint 10. Each discrete spring 16 may be in the form of a resilient bar or leaf spring and is mounted between the vamp 8 and a heel strap 20 of the heel restraint 10 so that the heel restraint 10 can undergo pivotal motion. The biasing means biases the heel restraint 10 in an orientation so as to extend around the upper heel 12 or heel top of the foot 6 as shown in FIG. 1.
  • The heel restraint 10 includes the arcuate heel strap 20 which, in turn, is made from leather. The heel restraint 10 further includes a plastic stiffener 22 mounted to the outside of the heel strap 20 so that the heel restraint 10 is stiffened. As shown in FIG. 1, the heel restraint 10 is substantially resistant to lateral bending when it is rotated down from the upper heel 12 and toward the sole 4 (see dashed lines). Accordingly, the heel restraint 10 substantially maintains its shape when it is moved along the heel 12 and toward the sole 4.
  • The heel restraint 10 extends from the vamp 8 which is elevated with respect to the sole 4. Accordingly, the free end of the heel restraint 10 can more freely move when the foot 6 moves within the sandal 2 during walking and is less prone to cause discomfort to the heel 12, than if the heel restraint 10 otherwise extended from the sole 4 thereby increasing the acute angle between the sole 4 and the heel restraint 10. Furthermore, the heel restraint 10 applies less pressure to the heel 12 owing to the cyclic action of the foot 6 during walking, than if the heel restraint 10 otherwise extended from the sole 4.
  • Operation of the sandal 2 will now be described with reference to FIG. 3.
  • Turning firstly to FIG. 3 a, the sole of the foot 6 initially presses down on the free end of the heel restraint 10 which causes the heel restraint 10 to retract toward the sole 4. The user fully slips his or her foot 6 into the vamp 8 and the heel restraint 10 then springs back away from the sole 4 so that the heel restraint 10 extends around the upper heel 12 of the foot 6. The foot 6 is then locked securely into the footwear 2 and is restrained from slipping from the footwear 2. Accordingly, the insertion of the foot 6 into the footwear can be readily achieved without the need to use the hands (or a hand operated tool such as a shoe horn) which would undesirably require the user to stoop.
  • Referring to FIG. 3 b, the user can use a toe 24 of his or her other foot (or another shoe) to retract the heel restraint 10 toward the sole 4. Pushing the foot 6 a small distance into the footwear 2 may assist in creating a gap 14 between the heel restraint 10 and the heel 12. The foot 6 is no longer locked into the footwear 2 and can then more readily slip from the footwear 2. Accordingly, the release of the foot 6 from the footwear can be readily achieved without the need to use the hands (or a hand operated tool such as a shoe horn) which would undesirably require the user to stoop.
  • A second embodiment of the present invention is shown in FIGS. 4 and 5 where like reference numerals refer to like features previously described. The heel restraint 10 extends directly from either side of the vamp 8 and includes a heel strap 23. The biasing means include a pair of discrete springs 16 mounted on either side of the rear of the single vamp 8. In turn, the heel strap 23 is mounted to the springs 16 so that the springs 16 are located between the vamp 8 and the heel strap 23.
  • The springs 16 are mounted at a distance 27 above the sole 4 so that a plane 26 of the heel restraint 10 approaches an orthogonal relationship with the skin surface (or a tangential plane 25) of the top of the heel 12. In practice, the angle between the plane 26 of the heel restraint 10 and the skin surface (or tangential plane 25) of the top of the heel 12 is greater than 70°. Because of this near orthogonal relationship combined with the pivotal mounting of the strap 23, a comfortable and a safe fit of the foot 6 within the footwear 2 is provided. In particular, the inner surface or apex of the heel strap 23 hugs the top of the heel 12 and thereby provides a comfortable fit.
  • As shown in FIG. 5, the stiff heel restraint 10 may define a neck portion 30 about which it can pivot so that the centre of rotation is located proximal to the vamp 8.
  • A third embodiment of the present invention is shown in FIGS. 6 to 8 where like reference numerals refer to like features previously described. The footwear 2 includes vamp means 32 (or an upper) for partially covering the instep of the foot 6. The vamp means 32 includes two separated instep restraints 8 a, 8 b each extending from either side of the sole 2. The rear instep restraint 8 a is located distal from the toes of the foot 6 and includes instep biasing means 29 for biasing the rear instep restraint 8 a to extend around the upper instep of the foot 6.
  • The rear instep restraint 8 a is of similar construction to the heel restraint 10 described in detail above. Accordingly, the rear instep restraint 8 a includes a rear instep strap 40. The vamp means 32 further includes a pair of anchor tabs 34 extending from opposite sides of the sole 4 and to which the heel restraint 10 and rear instep restraint 32 are pivotally anchored. The instep biasing means 29 includes a pair of torsional springs fast with respective anchor tabs 34.
  • Turning to FIG. 7, the rear instep restraint 8 a can be pivoted forward (from rear position R to forward position F) toward the toes of the foot 6 when the foot 6 is inserted into or removed from the footwear 2. This compliance of the restraint 8 a particularly facilitates insertion of the foot 6 into footwear 2 which includes orthotic (or orthopedic) soles. Upon insertion of the foot 6, the biasing means 29 pivots the restraint 8 a rearward to position R once again and, together with the heel restraint 10, securely locks the foot 6 within the footwear 2. In this manner, the footwear 2 has a safety fit when the foot is restrained in use, so that movement of the foot 6 relative to the footwear 2 is minimized and the foot 6 is prevented from involuntarily slipping rearward from the footwear 2.
  • The front instep restraint 8 b is located proximal to the toes of the foot 6 and includes a front instep strap extending directly from either side of the sole 4.
  • A fourth embodiment of the present invention is shown in FIG. 9 where like reference numerals refer to like features previously described. The biasing means, for biasing the heel restraint 10 to extend around the upper heel of the foot 6, includes a pair of resilient stretchable (e.g. woven elastic) fabric portions 50 extending between the heel restraint 10 and the vamp 8. The fabric portions 50 are located on respective sides of the footwear 2.
  • A fifth embodiment of the present invention is shown in FIG. 10 where like reference numerals refer to like features previously described. A limp waterproof heel cover 52 or fabric panel can extend between the heel restraint 10 and the sole 4. The heel cover 52 is sewn about its periphery to the footwear 2.
  • A person skilled in the art will appreciate that many embodiments and variations can be made without departing from the ambit of the present invention.
  • In the some embodiments, the heel restraint 10 extends from the vamp 8. The user can readily pivot the heel restraint 10 from the upper heel 12 and toward the sole 4 so that the foot can be slipped from the sandal 2. The intersection point (and pivot axis 18) of the heel restraint 10 with the vamp 8 can be varied.
  • In the first embodiment, the vamp 8 was made from leather. Alternatively, the vamp 8 may be made from fabric or plastic. Similarly, in the first embodiment, the heel strap 20 was made from leather. Alternatively, the heel strap 20 may be made from fabric or plastic.
  • In the first embodiment, the biasing means included a pair of torsional springs 16 a,b. In an alternative embodiment, the biasing means may include only one of the springs 16. The springs 16 may be made from rubber, plastic, metal or other suitable resiliently flexible material.
  • The first embodiment related to a sandal, however, the present invention can be equally applied to other forms of footwear such as shoes, slippers, sandals, sport shoes, runners, mules, slides, scuffs, backless sandals, slip-ons, athletic shoes or similar.
  • In some embodiments, the sole 4 was made from rubber. However, in alternative embodiments, the sole may be made from plastic or leather.
  • In the first embodiment, a gap 14 was formed between the heel restraint 10 and the heel 12. In an alternative embodiment, this gap 14 need not be formed.
  • In one embodiment with reference to FIG. 5, the heel restraint 10 may be integrally formed (or molded) from a resilient rubber strip or moulding, and therefore the biasing means may be integrally (or homogeneously) formed with the heel strap 23. The biasing means can include a pair of neck (or narrowing) portions on either side of the heel restraint 10 about which the heel restraint 10 can pivot.
  • In another embodiment with reference to FIG. 8, the rear instep restraint 8 a may be integrally formed from a resilient rubber strip or moulding. Accordingly, the rear instep strap 40, instep biasing means 29 and anchor tabs 34 may be integrally formed. The heel restraint 10 may be of similar construction to that previously described in the preceding paragraph and may be integrally formed with the rear instep restraint 8 a.
  • In one embodiment with reference to FIGS. 9 and 10, the heel restraint 10 may be pivotally affixed to the vamp 8 using pins or rivets. The footwear may or may not include a tongue.
  • In compliance with the statute, embodiments of the invention have been described in language more or less specific to structural or methodical features. It is to be understood that the invention is not limited to specific features shown or described since the means herein described comprises some of a plurality of forms of putting the invention into effect. The invention is, therefore, claimed in any of its forms or modifications within the proper scope of specification and the appended claims as appropriately interpreted by those skilled in the art.
