Abstract:
A ski binding including a sole plate to which a ski boot is secured. The sole plate is supported on a ski plate for rotatable movement of the sole plate about forward pitch and yaw axes located beneath a skier''s center of gravity. Means is provided for preventing movement of the sole plate relative to the ski plate about these axes when subjected to pitching and yawing torques occurring during normal maneuvers and for allowing said sole plate to be released for settable abnormal (excessive) pitching and/or yawing torques.
Abstract:
A device for securing a boot to a ski includes a support member disposed between the ski and a sole-element of the boot; one end of the support member is pivotally mounted to the ski to provide a displacement of the boot in a plane perpendicular to the plane of the ski, and the other end of the support member is releasable to allow this displacement. First hinge means connect the support to the sole-element and allows the boot to pivot about an axis perpendicular to the boot. Second hinge means connect the first hinge means to the support member and include a pivot axis transversely extending of the ski, the pivot axis of the first and second hinge means being in constant perpendicularity.
Abstract:
Ski-boot includes a rigid shell shaped to accommodate the foot, and a rigid cuff which is shaped to surround the ankle and is hinged on the shell so to be rotatable about a transversal reference axis; the shell being provided with a front sole and with a substantially duckbill-shaped front appendix which protrudes from the tip of the shell to form an extension of the front sole, and is structured so as to engaged in the front jaw of a specific ski fastening device; the front appendix having, on each lateral side, a respective side groove which starts on the appendix upper face at a distance from the appendix tip ranging between 10 and 20 millimeters, and continues by flanking the shell tip while increasing its depth, so to form a descending slope above which a corresponding prong of the front jaw of the ski fastening device is arranged.

The flexor unit (1) comprises: a flexor element (10) which is attached, attachable or integrally formed with a base element (30) for interaction and attachment with the ski binding (2) in a removeable manner. Further the base element (30) is provided with part of a snap-fit connector (31) for attaching the multi-element flexor unit (1) to the ski binding (2). Also disclosed is a ski binding (2) for housing the multi-element flexor unit (1).
Abstract:
The present invention relates to a telemark ski binding system that includes a first coupling configured to couple a ski to the toe of a ski boot and a second coupling configured to attach the ski to the heel of the ski boot. The second coupling may attach to the ski separately from the first coupling. The first coupling attaches to the boot using a freely rotating, releasable toe coupling design. The second coupling incorporates a flexible attachment that facilitates vertical movement of heel of the ski boot with respect to the ski and connects to the ski underneath or near the bellows of the boot.
Abstract:
Ski binding (10) for fixing a ski shoe that comprises an upper and a sole (11), having a front retaining element (12) associated with the front end of the sole, a rear retaining element (13) arranged to engage at the foresole or at the heel of the ski shoe, a tensioning means (15, 16, 17, 19) effective between front and rear retaining elements, and having a means, associated with the front retaining element (12) and pivotally mounted relative to the latter about a horizontal axis, for supporting the front end of the sole or sole-supporting means (28), wherein the pivotal axis (29) associated with that supporting means simultaneously defines the pivotal axis about which a structural unit (26) comprising the front and rear retaining elements is pivotable when the shoe heel is lifted or lowered. The sole-supporting means (28) associated with the front end of the sole is pivotable relative to the structural unit (26) and is lockable, as required, by a separate locking element (30).
Abstract:
The present invention relates to a spring cartridge for a ski binding, wherein the ski binding has a rotatable front binding part for attachment of a ski boot, and is in particular a telemark ski binding. In the binding the spring cartridge provides tension to a biasing cable which biases the rotatable front binding part, so as to rotate the front binding part so that an attached ski boot would be brought into contact with the ski to which the ski binding is attached.The spring cartridge comprises an extended hollow housing open at both ends, a compression spring held within the extended hollow housing and a pressure stub held partly within the compression spring.The pressure stub is structured with an extended portion having a cross dimension smaller than the interior size of the compression spring and a head having a larger size than the interior size of the compression spring. The extended portion extends within the internal hollow of the compression spring and is also hollow and provided with an internal screw thread in the hollow section for threadable engagement with an external screw thread at the end of a biasing cable of a ski binding, the biasing cable being threadable through the centre of the compression spring to the pressure stub.With rotation of the pressure stub this would thus lead to a change in the amount of the biasing cable held within the hollow section, when present, and thus change the amount of compressive force acting on the compression spring.
Abstract:
The present invention relates to a support system for use in relation to an articulation region of a boot. Embodiments of the present invention relate to a boot with a dorsal metatarsal articulation region that allows for articulation in the sagittal plane such as a telemark ski boot. One embodiment of the present invention relates to a telemark ski boot, including a shell, an articulation region, and an articulation support system. The articulation support system includes at least one tensile rigid region extending transversely between the proximal and distal sides of the articulation region. The tensile rigid region impedes rotation of the rear portion of the shell about the toe portion in a frontal plane. This form of rotation is often referred to as torsional rotation. The articulation support system may include one or more of a cable, an integrated shell portion, a material mesh, and/or other tensile rigid components which maintain bending flexibility. A second embodiment of the present invention relates to a method for increasing the torsional support characteristic of a telemark ski boot while maintaining the desired flexibility.
Abstract:
Methods for creating a piece of hard shelled footwear are provided. The method may include determining a first set of data, where the first set of data represents a three-dimensional shape of a foot. The method may also include determining a second set of data based at least in part on the first set of data, where the second set of data represents at least a portion of an exterior shape of a piece of hard shelled footwear. The method may further include fabricating a mold shape based at least in part on the second set of data. The method may moreover include fabricating the piece of hard shelled footwear in the mold shape.
Abstract:
The present invention relates to a ski binding that retains a boot to a ski in at least two independent operational states. One embodiment of a ski binding includes a toe receiving member and a releasable system. The toe receiving member is configured to engage the toe portion of the boot. The releasable system is configured to couple the toe receiving member to the ski in at least two independent operational states. A first state corresponds to a state in which the toe receiving member is allowed to freely rotate with respect to the ski. The first state is particularly useful in minimizing the necessary energy output for uphill travel. A second state corresponds to a state in which the toe receiving member is locked with respect to the ski. The second state is particularly useful in high performance downhill travel. The releasable system further includes an engagement mechanism and a switching mechanism. Additional states may also be included such as a third state in which both the toe receiving member and a heel portion of the boot are fixed with respect to the ski.
