摘要:
A binding for a cross-country ski shoe in which the shoe is mounted for pivotal movement about an axis transverse to the longitudinal axis of the ski. An elastic bumper exerts a return force on the shoe when the shoe is lifted from the upper surface of the ski. The elastic bumper is brought into a prestressed condition during the closing of the binding. The prestressing is achieved by either the displacement of the shoe with respect to the elastic bumper or displacement of the elastic bumper with respect to the shoe. This displacement may either be slidable or pivotal movement of a carriage.

Apparatus for connection to a cross-country ski for laterally guiding a ski shoe having a front end attached to the ski at a position forwardly of the rear of the shoe whose heel is vertically movable on the ski in the longitudinal median plane thereof includes a longitudinally extending guide rib adapted to cooperate with a longitudinal groove of complementary shape in the sole of the ski shoe. The groove successively includes, from front to rear, a first region beneath the toes of the foot of the wearer of the shoe, a second region beneath the ball of the foot of the wearer, a third region beneath the arch of the foot of the wearer, and a fourth region beneath the the heel of the foot of the wearer. The rib has opposite lateral sides defining the width of the guide, and a top surface defining the height of the guide. Both the slope of the sides relative to the longitudinal median plane of the ski, and the height of the guide, are nonconstant functions of the length of the guide. The length of the guide rib can be modified to accommodate different shoe lengths. Specifically, the end of the rib is configured to facilitate the breakage of predeterminate section(s) of the rib, depending upon the particular shoe size with which the rib is to be used. Such configuration can include a number of transverse score lines at which point an unneeded end section of the guide rib can be broken off.

The process consists in embedding two longitudinal ends (23, 24) of an assembly component (21) making up the binding mechanism into stationary parts (16) or parts unitary with the ski (27a). According to one embodiment, the locking system of the ski boot is composed of a locking piece (2) which slides longitudinally, and the assembly component is constituted by this movable locking piece (21). The device also comprises a toggle joint system which draws the locking piece (21) into the boot-locking position, and one of the fulcrum members (27a) of the toggle joint system is anchored on the ski so as to produce the vertically-oriented recessed housing of one end (24) of the assembly component (21).
摘要:
A cross-country ski binding having a linkage element for pivotal mounting relative to a ski about a first axis; a latching element pivotally connected to the linkage element about a second axis between a retention position, for retaining a boot to the binding, and a release position, for permitting the boot to be removed from the binding; a device for biasing the latching element toward the retention position, wherein the biasing device is connected between the latching member and a member fixed with respect to the ski. The biasing device is compressed in a direction that is offset with respect to both the first and second axes. The binding according to the invention omits the use of a stirrup member which is used in particular known ski bindings.
摘要:
Cross-country ski binding for a shoe or boot having a transverse journal axle. A fixed and movable jaw receive the journal axle and allow pivotal movement of the shoe or boot relative to the ski. A toggle or overcenter linkage both biases and latches the movable jaw in a closed position and guide the movable jaw in its movement relative to the fixed jaw.

Apparatus for a cross-country ski having a longitudinal median plane for laterally guiding a ski shoe whose toe is attached to the ski on top of the ski and whose heel is vertically movable in the median plane on the ski includes a longitudinally extending guide rib adapted to be attached to the top of the ski. This rib is symmetrically located with respect to the median plane of the ski and has top and lateral side surfaces adapted to cooperate with a longitudinal groove in the sole of the ski shoe. The groove has a bottom and lateral side surfaces for receiving the rib when the sole of the shoe seats on the top of the ski. Finally, a resilient member is interposed between the bottom of the groove in the shoe and the top of the ski for resilient compression in response to the seating of the sole on the top of the ski.
摘要:
System comprising a cross country ski boot and a device to hold the front of the boot on a ski. The holding device (3) holds the front part (17a) of the sole (17) of the boot (1) flat on the upper part of the ski, in a holding zone extending between the front end of the sole and a rear limit (P, P1) thereof, located substantially under the metatarsal-phalangeal joint (A) of the skier's foot, and the boot (1) is shaped so that in the resting position the rear part (17b) of the sole is released obliquely from the upper part of the ski, i.e., the heel (17c) of the boot is normally raised.
摘要:
A safety binding for a cross-country ski including a longitudinal rib bordered laterally by two longitudinal surfaces which are substantially planar and are adapted to engage a groove in a shoe sole. The rib is independent of and displaceable laterally with respect to the longitudinal surfaces and supports an apparatus defining a transverse journal axis around which the anterior zone of the shoe is adapted to pivot. Also provided is a locking apparatus for immobilizing the rib in a skiing position in which the rib is substantially aligned with the longitudinal axis of the ski and for permitting lateral displacement of the rib in response to a lateral force on the rib which exceeds a predetermined threshold produced by the locking apparatus. This binding has a mass and a cumbersomeness which is comparable to the mass and cumbersomeness of a conventional binding.
摘要:
A lateral guidance and support apparatus for a shoe fixed at its front end on a cross-country ski. The apparatus includes a rib attached to the ski which is adapted to engage a groove in the sole of the shoe having substantially the same cross-sectional configuration and area as the rib. The rib and the groove both include an anterior metatarsus support zone for supporting the metatarses of the foot and a posterior heel support zone for supporting the heel of the foot. The height of the rib and the depth of the groove are chosen such that in the anterior support zone of the metatarses the height of the rib is less than the depth of the groove. As a result, in this zone the sole is supported on the upper surface of the ski in two zones on either lateral side of the rib. In addition, the height of the rib and the depth of the groove are also chosen such that in the posterior heel support zone the height of the rib is greater than the depth of the groove. As a result, the heel of the boot is supported only on a central zone on the upper surface of the rib. Consequently, the boot is supported at three points on the ski, thereby increasing the stability of the skier during skiing and increasing the feeling of attachment to the ski.

A binding for a cross-country ski shoe in which the shoe is mounted for pivotal movement about an axis transverse to the longitudinal axis of the ski. An elastic bumper exerts a return force on the shoe when the shoe is lifted from the upper surface of the ski. The elastic bumper is brought into a prestressed condition during the closing of the binding. The prestressing is achieved by either the displacement of the shoe with respect to the elastic bumper or displacement of the elastic bumper with respect to the shoe. This displacement may either be slidable or pivotal movement of a carriage.
