Ski binding

An apparatus for facilitating a longitudinal adjustment of ski-binding parts having a guide rail adapted to be fastened on the ski and being provided with two laterally spaced guide tracks. The guide rail has a toothed bar which extends in longitudinal direction of the apparatus, with which toothed bar is associated a locking member which is provided on a slide plate. The slide plate is covered by a guide plate which is supported on the guide rail and which carries a ski-binding part. In each of the guide plate and slide plate there is arranged a recess, and if desired, a shoulder for the two compression springs which bias the guide plate. An extension member is operatively connected to the slide plate for facilitating a movement of the locking member on the slide plate against the force of the compression springs to effect a disengagement from the toothed bar on the guide rail. The extension member extends in transverse direction of the apparatus and is adapted to be manually operated.

A heel holder includes a ski brake, a bearing block which is arranged on a base plate, and a housing which is supported swingably on the bearing block, wherein the housing carries a sole hold-down member which is under the influence of a spring, and is held in the skiing position by a locking lever or a pawl, and wherein braking mandrels of the ski brake, with respect to their swivelling movement to the braking position, are controlled by the housing. In order to permit an opening of the heel holder and a swivelling of the ski brake into the braking position in a simple manner when only the front jaw of the ski binding has released, the ski brake is provided with a stepping plate and is operatively connected through a coupling or operating member to the locking lever or the pawl.

Heel holder combined with a ski brake

A safety ski binding has a bearing block with a locking projection, and a sole holder is supported on the bearing block for pivotal movement between a downhill skiing position and a released position. A locking part pivotally supported on the sole holder has a cam which engages the locking projection and has a surface on the opposite side thereof. a spring housing has one end pivotally supported on the bearing block and has an opening in the opposite end. A piston slidably supported in the spring housing has a piston rod which extends through the opening and slidably engages the surface on the locking part. A spring disposed in the spring housing urges the piston toward the locking part, thereby urging the cam against the locking projection. A mechanism is provided to obstruct sliding movement of the piston rod along the locking part surface from a first location thereon to a second location in which the effect of the spring on the locking part is reduced or absent. A manually actuable mechanism is provided for temporarily rendering the obstructing mechanism ineffective.

A ski brake has a base plate and has a stepping plate which is hinged to the base plate by means of a transverse axle and is biased by an erecting spring, in which stepping plate or on which stepping plate are pivotally supported two braking mandrels by their support sections. Pivotal movement of each braking mandrel occurs either by means of a coarse thread provided on its support section which operatively engages an internal thread of a structural part fixed on the stepping plate or movable relative to the stepping plate, or by means of a helical slot which guides the transversely extending section of the braking mandrel.

Ski brake

A ski brake having a pair of braking legs, which ski brake is pivotal by a force applied by a ski boot or by a sole plate to a pedal about an axle which extends substantially at a right angle with respect to the longitudinal axis of the ski in a mounting member which is secured to the ski, between a braking position against a spring force into a retracted position. Each braking leg has a braking mandrel with a bent segment therein which extends from the braking mandrel toward the longitudinal axis of the ski. The braking leg is held totally above the upper surface of the ski and within the width of the ski in the retracted position of the ski brake by the pedal which is stepped down upon by the ski boot or by the sole plate. In the braking position of the ski brake, the braking mandrel is held lying next to the ski edge and the braking leg projects below the running surface of the ski. The braking leg is pivotal about a swivel axle which extends in longitudinal direction of the ski when the ski brake is in the retracted position. The end of the braking leg remote from the braking mandrel is provided with a crank segment which engages a control part pivotally secured to the pedal. The control part is engageable with the upper surface of the ski as the pedal moves toward the retracted position of the ski brake to effect the aforementioned movement of the braking mandrel to a position oriented within the width of the ski.

An apparatus for facilitating an adjusting of the position of a front and/or rear jaw of a ski binding. The apparatus has a guide rail which is adapted to be secured on the upper surface of a ski with the jaw being movable along the guide rail. One of the guide rail and the jaw is provided with a toothed bar which extends perpendicularly with respect to the upper surface of the ski. The other of the guide rail and the jaw has a tooth detent arranged movably in a transverse direction of the ski. A spring is provided for biasing the tooth detent into engagement with the toothed bar. The tooth detent is provided at the end of a single lever pivotally supported on an axle which extends in longitudinal direction of the ski on the side surface of the housing of the jaw, which side surface is adjacent the toothed bar of the guide rail.

A safety ski binding has a support member supported for pivotal movement about a vertical axis, and a sole holder is supported on the support member for pivotal movement about a horizontal axis. A lever supported on the support member for pivotal movement about a horizontal axis has a first locking element engageable with a second locking element on the rear of the sole holder and has a control surface on its side opposite the first locking element. A housing for a release spring is supported on the support member for pivotal movement about a horizontal axis and has a sliding element which the release spring urges against the control surface on the lever. A centering spring cooperable with the support member and housing pivotally urges the housing to a position in which the sliding member is engaging the control surface of the lever. A second set of locking elements yieldably resists pivotal movement of the support member.

A ski brake has an operating pedal pivotally connected to a wire braking bar with two braking mandrels. The pedal is pivotal about a first ski fixed axle and the bar is pivotal about a second axle which is parallel to the first axle and supported for movement relative to the pedal in directions substantially parallel to the longitudinally axis of the ski. An upwardly projecting path extender which is disposed in the path of movement of the second axle raises the second axle and the braking mandrels to positions spaced above the surface of the ski, and then lowers the second axle to a position adjacent the surface of the ski as the ski brake moves between its retracted and braking positions. A mechanism is provided for pulling the braking mandrels laterally inwardly as the ski brake approaches the retracted position.

A sole or heel holder of a ski binding has a housing and sole down-holding member pivotally supported on a base and latched in a closed position for skiing by a U-shaped locking pawl which is pivotally supported on the housing, has a roller at the end of each leg, and has a row of notches along the bight. The bight is substantially vertical, one roller is disposed against the down-holding member, and the other roller is disposed against a detent on the base. A support part is pivotally supported on the base and positionally adjustable relative to the housing by means of a setscrew, and a spring-loaded locking element is slidably supported thereon and selectively engages the different notches in the pawl in response to rotation of the setscrew. A release lever is pivotally mounted to the base and cooperates with the pawl through a linking member for effecting a voluntary release of the latched housing and down-holding member.

Sole or heel holder

A ski brake construction having a pair of blade members which are located on laterally opposite sides of the ski and can be pivoted between a cocked or ready or downhill position wherein the blade members extend approximately parallel with respect to the upper surface of the ski and a braking position wherein the blade members extend approximately perpendicularly with respect to the upper surface of the ski. The blade members are pivotally secured to a mounting device and are movable about the axis of two axles, one of which is stationary and the other of which is movable. The movable axle is slidable in a slot provided in the mounting device.

A sole-support mechanism having a stepping plate for the heel of a ski boot which is urged by a spring-loaded ski binding part, in particular by a heel holder, toward a front jaw which forms a ski-fixed support in longitudinal direction of the ski, and is supported on a guide plate, which plate is movable in longitudinal direction of the ski through the force of at least one thrust spring over a holding rail or the like, wherein the upper side of the sole-support mechanism consists, if desired, of a material which has a low friction coefficient or has a layer of such a material.
