Abstract:
Sole for a cross-country, touring or Telemark ski shoe the front section of which comprises, for the purpose of binding a shoe of this type onto a cross-country, touring or Telemark binding between ball area and rear end, in particular at its rear end, means for engaging a clamping element so that the front sole section can be clamped between its front definition and the aforementioned engaging means. Into the front section of the sole is embedded a reinforcing element. The latter extends between the front definition of the sole and the engaging means for the clamping element in such a manner that the resulting tensional load vector lies above the zero line of the reinforcing element, which extends approximately parallel thereto.
Abstract:
A boot/binding device apparatus assembly for a boot on a gliding member is of the type including an arrangement for binding the front end of the boot, the rear end of the boot being free to be raised with respect to the gliding member. The assembly includes an arrangement for control and continues elastic return of the boot towards the gliding member, located at the rear of the binding device of the front end of the boot. Advantageously, the control and elastic return arrangement is constituted by an anchoring device for the binding device cooperating with anchoring apparatus associated with the boot, at least one of the anchoring device of the boot or of the binding device being provided with an elastic return mechanism.
Abstract:
A combination of a ski binding (10), particularly cross-country, touring or telemark binding, and of a boot (11) adapted thereto are shown, the front end of which is held by a resiliently biased clamp member (12; 48) in the binding (10) in such a way that the heel (13) of the boot (11) can be freely raised during ski touring or cross-country skiing. The clamp member (12; 48) engages on the forward sole (15) of the boot (11) particularly between the ball area and the rear end of the same, and preferably on the underside of the boot forward sole (15).
Abstract:
A cross-country ski binding, especially a hiking ski binding which includes a toe iron adapted for mounting on a ski top and having cheeks and sole catches for the front part of a ski boot sole. A heel unit has a cable with end tension springs. Corresponding side cable units connect the tension springs to the toe unit. Each cable unit includes a side cable with a forward end releasaby connected to the toe iron unit. A close wound coil spring is slidable on the side cable between the forward end and a rear stop member. A threaded connecting member has an internal thread and is threaded on the coil spring. The connecting member has an external threaded into the forward end of the tension spring. The threaded position on the sliding closely wounds coil spring with its movement on the cable.
Abstract:
A cable ski binding comprised of a toe iron having a boot sole support and boot toe lateral movement side restraint surfaces, a toe bail for clamping the top surface of the toe end of the sole extending out from the toe end of the boot to the sole support plate, a cable for securing the boot between the said lateral side restraints and under the said toe bail, a dual purpose heel assembly having a heel lever for securing the cable to the heel of the boot and a rocker means with two opposing elongate members, one of which acts against a spring and the other having a near horizontal surface aspect and attached to the rear most end of the cable loop. Sufficient stress on the cable causes the rocker to rotate and thus allows for the effective lengthening of the cable relative to the length of the boot while being continuously opposed by an increasing torque applied to the rocker by the spring through the moment arm of the former elongate member. The same heel lever/rocker mechanism alternatively serves to releasably lock the heel of the boot down as a safety release device by levering the rear heel bail which has its lower extent fixed to the surface of the ski so that the heel is releasably clamped down on the ski; the said bail exerting a downward force an a near horizontal surface aspect of the secondary elongate member. Sufficient upward forces of the heel cause the rocker to rotate while being opposed by the spring acting on the former elongate member, until the said horizontal surface becomes nearly vertical and thus allowing the bail to slip off of the secondary elongate member surface, releasing the heel and heel lever assembly.
Abstract:
A ski mountaineering binding, used for both alpine ski touring and downhill skiing, comprises a subassembly of ski boot binding components used for alpine ski touring, utilizing a hinged flexible touring plate under the sole of a skier's boot, and a subassembly of ski boot safety plate binding components used for downhill skiing. The subassembly of alpine ski touring ski boot binding components during downhill skiing are non flexibly secured from toe to heel, after the flexure interfitting of the rear of the hinged flexible touring plate to a non flexible downhill plate, to which the front of the hinged flexible touring plate is always pivotally secured. During alpine ski touring and downhill skiing the six way safety release functions of the downhill plate safety binding are potentially immediately available. During alpine ski touring a spring force applied at the pivotal securement of the hinged flexible touring plate is stronger at smaller angle positions of the ski boot relative to the ski and becomes weaker at larger angles, thereby making level or near level walking strides easier, yet making hillside side steps more convenient and safe, as the ski at these smaller angles tends to remain closely underneath the ski boot.
Abstract:
A safety ski binding comprises a sole grip pivoted on an end of a sole-supporting plate elastically connected to the ski by a flexible cable tensioned by a spring winder incorporated in the plate. A device for automatically opening the sole grip, after removal of the sole grip from the ski by withdrawal of the cable but before the cable is fully withdrawn, comprises a projection on the winder which actuates a lever to pull or push a transmission member which either disengages a bolt retaining the heel grip, or directly tips the grip open against the action of a biasing spring.
Abstract:
A connection between the ski and the skiing boot is provided for by a separate soleplate. A plate-holding device engages the soleplate behind the heel of the boot. An abutment for the soleplate is mounted on the ski. The plate-holding device normally urges the soleplate against the abutment and releases the same in response to an overload acting in a vertical and/or horizontal direction. The abutment consists of a lever, which is pivoted to the ski on an axis which is transverse to the longitudinal direction of the ski. Said lever has a free end portion extending toward the rear end of the ski. A disc is provided on the underside of the soleplate and is adapted to be approximately coaxial to the tibia of the skier and bears on the free end portion of the lever. At least two bearing blocks are secured to the ski below the soleplate and support the soleplate before and behind the disc. The plate-holding device comprises a known, spring-loaded detent member, which engages a wedge-shaped notch at the rear end of the soleplate. The apex of said notch is rearwardly and downwardly inclined.
Abstract:
A flexor unit for a ski binding, in particular a cross country or touring ski binding, including a flexor element which is attached, attachable or integrally formed with a base element for interaction and attachment with the ski binding in a removable manner, the flexor element comprising a single piece double section element with a front flexor portion and a rear flexor portion, the flexor element further including a pin receiving slot between the front and rear flexor portions, the pin receiving slot being sized and shaped to receive a rotation pin of a ski boot.
Abstract:
The invention is a device for removably blocking a central-front part of a ski boot to a ski platform for actuating a Telemark technique. The boot sole (51) forms, at a bottom thereof, two lateral edges, internal and external (52A, 52B). A plate (1) is blockable to the ski platform, a blocking device (17, 18) constrained to the plate, which bear at least two ratchets. The ratchets are associated with the bottom of the boot supported by the plate, to corresponding edges of the internal edge (52A) and external edge (52B). An activator (16, 24) for the blocking device is supported by the plate, defining two configurations of the blocking device, respectively inoperative (11), with a disengagement of the ratchets from the corresponding edges (52A, 52B) and operative (12), with a blocking of the two edges against the plate (1).
