Definitions

  • the present disclosure relates to a footwear product as set forth in claim 1. It further relates to a method
  • Footwear products with high heels are fairly common in fashionable ladieswear. They bear some danger of twisting the ankle, and related injuries.
  • high heels mostly exhibit a very slender shape and are attached to an upper part of the footwear at a very small attachment area. Thus, they break easily, and at a comparatively low tilt angle, which limits the momentum acting on the bearer's ankle, and accordingly the risk of serious injury.
  • the bearer's forefoot is in contact with the ground, which enables the bearer to react and control the motion, at least to a certain extent.
  • platform soles are used for reasons of aesthetics or other effects. A platform height of these platform soles is typically larger than several centimeters and may reach up to several ten centimeters.
  • the bearer's entire foot is disconnected from the ground by a fairly large distance.
  • the effect is comparable to stilt walking with the foot being rigidly attached to the stilt. Twisting the ankle or stumbling may thus easily result in a large momentum acting on the ankle, with the resulting danger of severe ankle injuries, or falling down, or both.
  • the knee, or soft tissue stabilizing the knee may be in danger of injury, for instance due to lateral bending.
  • a footware product in particular a shoe, which allows separation of a base or sole section upon danger of falling or twisting the ankle, such that the bearer may "step off” the platform sole. Damage may thus be avoided. It may in more specific instances be further found desirable, that the footwear product is not damaged by this separation, but may easily be reassembled. It may furthermore be found desirable that the separation does not occur arbitrarily, as in the case of the above mentioned breaking off a heel, that is, actually destroying the footwear product, but under controlled or controllable conditions and/or in a controlled or controllable manner.
  • said separation is automatically triggered by forces acting upon a certain tilt of the platform sole, and/or be triggered purposefully by forces induced by the bearer in performing certain foot movements when the bearer feels in jeopardy of falling or twisting the ankle.
  • EP 1 864 585 discloses a footwear construction in which a heel is secured relative to the underside of a sole member by means of a snap fit connection.
  • the snap fit connection is provided to securely and firmly lock the heel to the sole member.
  • the embodiments disclosed in FR 2 655 521 , EP 2 474 245 , DE 10 2008 017 674 , FR 2 980 079 and CN 105639848 exhibit interchangeable heels, wherein the interchangeable heels are fixed to a sole or other part of the footwear product by magnets.
  • connection interfaces comprise bosses or studs such as to secure the heel members of said embodiments against lateral displacement and disconnection due to momenta being effective at the connection interface.
  • US 2007/0000152 , US 2,065,325 , US 2,009,876 and US 2,478,810 disclose embodiments wherein outsoles or heel lifts are attached to footwear products by means of snap fit connections.
  • the attached outsole is rather flat, and requires manual operation to detach the respective outsole or heel lift member from the footwear product.
  • heel members are interchangeable, wherein they are connected to an upper part of the footwear product by threads, a system with locking knobs, or rigid snap fit connections.
  • a heel is attached to another part of the footwear product by a bayonet locking mechanism.
  • a footwear product of the type initially mentioned.
  • a footwear product shall be provided in which the danger of ankle injuries or falling down while walking in a footwear product with high heels and/or platform soles is reduced when compared to the art.
  • a footwear product shall be provided in which a sole member or heel member separates from the part of the footwear product in which the bearer's foot is received when the bearer steps on the footwear product and the sole or heel member reaches or exceeds a certain title angle.
  • a footwear product wherein the footwear product comprises a top member and a base member.
  • the footwear product may in particular be a shoe.
  • Each of the base member and the top member may be provided in one single part or may in turn be assembled from sub-members.
  • the top member is adapted to receive a foot.
  • the top member comprises a front section and a heel section, wherein in certain embodiments the front section may comprise and extend from a toecap.
  • the top member exhibits a bottom side and an upper side, wherein the top member is closed at its bottom side and is open at its upper side at least in the heel section such as to receive a foot through the opening at which it is open at the upper side in the heel section.
  • the top member may for one non-limiting instance comprise a closed compartment with an opening at the upper side in the heel section to receive a foot therethrough.
  • the top member may comprise one or more straps spanning the upper side to receive a foot between the straps and a closed bottom. It is understood that the named instances are given as examples only, and other embodiments of top members of a footwear product are possible within the scope of the present disclosure, although not being explicitly mentioned.
  • the base member comprises a bottom side and an upper side, and a platform height between the bottom side and the upper side of the base member.
  • the bottom side of the base member is adapted to contact a ground, in particular instances in that an outsole is provided on the bottom side of the base member.
  • the footwear product as herein disclosed is adapted and configured to be functionally assembled from at least the top member and the base member, wherein the upper side of the base member is oriented towards the bottom side of the top member. It is understood that if the base member is directly attached to the top member, the upper side of the base member faces the bottom side of the top member. Such, the top member may be supported by the base member which is provided below the top member when a bearer walks in the functionally assembled footwear product.
  • a connection interface is provided between the base member and the top member.
  • the connection between the top member and the base member may be direct, such that the bottom side of the top member is provided adjacent the upper side of the base member, or indirect, with one or more intermediate members provided between the top member and the base member when the footwear product is functionally assembled.
  • the connection interface is adapted and configured such that the connection interface is separable by a momentum applied at the connection interface.
  • connection interface is adapted and configured such that the connection interface is separable by a torsional momentum around an at least essentially vertical axis.
  • an interlocking system be provided as a connection system which works analogously to a clipless bicycle pedal system.
  • the bearer may support the base member on the ground and perform an adduction or abduction of the foot around the axis of the lower leg in order to exert a torsional momentum at the connection interface to disengage the interlocking system and thus to separate the base member from the top member.
  • connection interface is adapted and configured such that the connection interface is separable by a bending momentum, in particular around a toe-heel axis of the footwear product, or in other words, in a frontal plane of the footwear product.
  • the bearer may exert this momentum in particular in two ways. She or he may either support the base member on the ground and perform a pronation or supination of the foot, that is, turn the foot around its longitudinal, toe-heel, axis. Thus, a bending momentum becomes effective at the connection interface to separate the base member from the top member.
  • a bending momentum of the type mentioned is also induced by the bearer's weight if the base member of the footwear product starts to tilt on the ground and the bearer is in danger of twisting her or his ankle.
  • the bearer may furthermore support the base member laterally against a firm object, like for instance a step, and perform an adduction or abduction of the leg towards the firm object.
  • a lateral force is exerted at the top member of the footwear product
  • a counteracting lateral force is exerted at the bottom of the base member
  • a resulting bending momentum becomes effective at the connection interface to separate the base member from the top member.
  • the separation should only be effected if the momentum effective at the connection interface exceeds a threshold value.
  • This threshold value should be chosen such that the base member remains securely fixed to the top member during normal use of the footwear product.
  • the threshold value should be chosen such that a separation of the base member from the top member occurs if a momentum becomes effective at the connection interface which is sufficiently low in order not to cause any or at least not any serious harm or injury to the bearer's ankle or knee.
  • the skilled person may easily determine suitable threshold values.
  • a connection system which is provided to couple the base member to the top member may be provided such that the disengagement threshold is adjustable.
  • top, base, bottom, upper, front, back, lateral, and the like are related to the position of the footwear product for intended use.
  • toe and heel indicate well-defined directions or positions in connection with a footwear product. That is, when a bearer stands on the ground bearing the footwear product.
  • designations of directions and relative positions have clear and unique meanings in the context of a footwear product as such.
  • one or more base members may be provided.
  • one single base member may be provided which extends from a toe region to a heel region, and may be provided with a constant or a variable platform height, which may increase from a front or toeside end to a back or the heelside end.
  • a minimum platform height may measure 5 cm or more, more in particular 7 cm or more, and even more in particular 10cm or more.
  • a first base member may be provided in the front or toe region of the footwear product and a second base member may be provided in the back or heel region of the footwear product. More platform members may be provided, with equal or different platform heights, which may in certain embodiments increase from the front to the back, and wherein further a minimum platform height may be 5 cm or larger.
  • the base member may be provided as a single heel member.
