Abstract: An impact absorbing footwear device employs opposed planar sole portions engaged by a selective resistance coupling that biases the opposed planar sole portions in a non-linear manner in response to forces exerted by the wearer against the sole portion in frictional contact with a floor surface. The planar sole portions are disposed in a footwear appliance that takes the form of an athletic shoe sole. The selective resistance coupling includes a plurality of resilient deformation members that engage the planar sole portions in an opposed circumferentially aligned manner, selectively deform in response to pressure exerted by the wearer for preventing ACL and other impact related injuries, and recover to an undeformed rest position without breakaway to allow the wearer uninterrupted usage while dampening forces that surpass an injury threshold from the resilient deformation that allows the planar sole portions to temporarily misalign.

Abstract: A prosthetic appliance disposes a plurality of elongated, resilient members in a circular configuration around a pivot point representing a skeletal joint such as an ankle, wrist or shoulder. The resilient members are resilient and adapted to deformable respond to pivoting forces of the fulcrum, and forcibly deform in response to the pivoting of the shaft forcing the fulcrum against the resilient members. The circular orientation of the resilient members pivot the shaft orthogonal to the base from which the resilient members extend, such that the resilient members bias the fulcrum and shaft in the orthogonal position at a rest position. Forces drawing the shaft off-center disposed the fulcrum against one or more of the resilient members and causing resilient deformation and counterforces against the fulcrum back to the centered rest position. In response to pivoting movement, the resilient members apply increasing forces for biasing the pivoting shaft.

Abstract: A force absorbing device for a footwear appliance includes a shoe sole having a planar sole surface, such that the shoe sole is adapted to be disposed against a ground surface such as turf, grass or dirt. A ground interface member having a general appearance of a footwear cleat extends from the planar sole surface. Within the sole, the ground interface member couples to a force mitigation assembly for absorbing forces against the cleat. The force mitigation assembly includes an elastic field of a resilient, compressible material, and an inclined surface is disposed against the elastic field and oriented to compress the elastic field. A linkage or connecting surface transmits a displacement force for disposing the inclined surface across the elastic field, where the inclined surface compresses the elastic field as it moves across. In response, the elastic field exerts a counterforce against the ground interface member.

Abstract: An impact absorbing ski binding interface device includes an elongated top plate having a toe end and a heel end adapted to engage a boot toe and a boot heel, respectively, and a bottom plate adapted to engage a ski, thereby securing the device between the boot and ski. A plurality of constant force spring linkages between the top plate and the bottom plate include a constant force spring linkage between the toe end and the bottom plate, and a constant force spring linkage between the heel end and the bottom plate, such that each of the constant force spring linkages have an opposed pair of deformable members for exerting a counterforce to vertical displacement forces between the top plate and the bottom plate for load mitigation.

Abstract: A force absorbing device for a footwear appliance includes a shoe upper and a shoe sole having a planar sole surface, such that forces between the shoe upper and planar sole surface in ground contact are absorbed by storage and controlled release of kinetic energy in an elastic or resilient field. A footwear article such as a shoe or boot includes a split-sole system that redefines a shoe sole as coplanar surfaces having a force mitigating interface for receiving sudden forces and effectively mitigating these forces by storing kinetic energy and releasing it over time. An elastic field in the force mitigation interface is defined by a resilient material adapted to deform in response to the received force. Frictional engagement between the upper and lower sole may also be augmented by surface characteristics such as dimples, voids and lubricants, in addition to interference engagement with an elastic field.

Abstract: A ski binding reduces a likelihood of injury to the anterior cruciate ligament (ACL) and the tibia is accomplished by absorption in the binding to limit loads transmitted through the boot-binding interface. Release based on an injury threshold includes a binding response tower attached to the ski and adapted for selective engagement with the ski, such that the binding response tower permits biased vertical and lateral horizontal displacement, prior to a release threshold. The binding is in communication with the boot heel and is adapted for slideable engagement in response to vertical and lateral forces exerted from the boot heel. The binding response tower adapted to disengage, or release upon reaching at least one a predetermined lateral displacement or a predetermined vertical displacement, such as when the boot heel is forced sufficiently sideways or upwards due to skier movement that would tend to cause an ACL injury.

Abstract: A force dissipating device in a footwear appliance includes an actuator responsive to a displacement force from a shoe sole surface, and an elastic field of resilient, compressible material. The elastic field is elongated in a direction aligned with the displacement force, and an inclined surface is attached to the actuator and disposed against the elastic field. The actuator is adapted for movement parallel to the elastic field, while the inclined surface is oriented to compress the elastic field in a direction defined by the inclined surface. The inclined surface is oriented at an angle to compress the elastic field in a direction substantially perpendicular to vertical actuator displacement, thus providing a constant region of opposed, compressive force that is generally constant, rather than increasing with displacement distance.
