Abstract: 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.

Abstract: A release binding has a swivel element mounted on a base plate and a support member supported on the swivel element for pivotal movement about a vertical axis. A housing with a sole holder is pivotally supported on the support member by a horizontal axle. A notch carrier is supported for reciprocal horizontal movement in the support member and has a sector-shaped notch with a curved recess at the apex thereof. An upright extension is provided on the swivel element and a spring urges the notch carrier into engagement therewith. Engagement of the extension with side surfaces of the notch recess inhibits pivotal movement of the support element. Cam surfaces provided on the housing are engaged by the notch carrier so as to resist a pivotal release movement of the housing, during which movement the cam surfaces displace the notch carrier against the force of the spring, thereby disengaging the extension from the notch recess.

Abstract: A ski binding front jaw has a cylindrical sleeve supported on a ski-fixed housing for axial movement parallel to the longitudinal axis of the ski in response to movement of ski boot engaging sole holders. An adjusting screw has an end portion rotatably and axially slidably supported in the sleeve, a threaded portion spaced from the end portion which threadedly engages an abutment, and a central portion of lesser diameter than the end portion adjacent thereto. A hollow cylinder is rotatably and axially slidably supported on the sleeve coaxial therewith by a first inner surface and has a second inner surface of greater diameter than the first surface adjacent thereto. The sleeve has a plurality of circumferentially spaced radial openings, and a spherical ball is disposed in each opening. The radial distances between the screw central portion and cylinder first surface and the screw end portion and cylinder second surface substantially equal the diameter of the balls.

Abstract: A safety ski binding has a connecting member which can releasably engage the ski shoe during chair-lift travel to prevent loss of the ski should the ski binding inadvertently release. The connecting member is U-shaped, has its bight pivotally supported on the ski binding, and has two legs which converge inwardly toward each other. The free ends of the legs are bent inwardly and extend toward each other. A stepping plate is provided below the ski shoe sole and aligned receiving openings are provided on opposite sides of the shoe sole and the stepping plate. The connecting member is pivotal about its bight between an engaged position and a disengaged position in which the free ends of the legs are respectively disposed in the receiving openings in the ski shoe sole and the stepping plate.

Abstract: A ski brake having two braking legs, which in the braking position project next to the two ski edges below the running surface of the ski. The braking legs are the free ends of at least one braking bar which is formed preferably of a spring wire by being bent and curved, which braking bar can be swung against a vertically acting spring force of return spring which is produced when a ski boot or a sole plate urges the ski brake from the braking position into a retracted position, in which position the two braking legs are supported lying approximately parallel with respect to and above the upper surface of the ski, which vertical force is diverted by guide means substantially at a right angle with respect to the longitudinal axis of the ski and thus the braking bars are either spread apart or pulled in.

Abstract: A ski binding mounted on a carriage reciprocally supported on a guide rail secured to a ski. A ski brake having a cam surface thereon is pivotally secured to the ski binding. An operating cam is secured to the guide rail or a component fixed to the ski and operatively engages the cam surface to (1) hold the ski brake in the retracted position when a ski boot is clamped in the ski bindings on the ski, and (2) effect a movement of the ski brake to the braking position when the thrust springs urge the ski binding and supporting carriage to its forwardmost position.

Abstract: 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.

Abstract: 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.

The braking legs are the free ends of at least one braking bar which is formed preferably of a spring wire by being bent and curved, which braking bar can be swung against a vertically acting spring force of return spring which is produced when a ski boot or a sole plate urges the ski brake from the braking position into a retracted position, in which position the two braking legs are supported lying approximately parallel with respect to and above the upper surface of the ski, which vertical force is diverted by guide means substantially at a right angle with respect to the longitudinal axis of the ski and thus the braking bars are either spread apart or pulled in.

Abstract: A holding plate is secured on the top surface of a ski and pivotally supports a support frame. The support frame is a piece of wire material bent preferably into the shape of a square or an omega, the sections of which are preferably coplanar and at least one section of which serves as the pivot axle therefor. A torsion spring encircles said one section of the frame, has two legs with eyelets which respectively grip adjacent sections of the frame, and has a central section which rests against the holding plate. An operating pedal is releasably mounted on the support frame by resilient fastening clamps fabricated from the material of the operating pedal, at least one fastening clamp being engaged with each section of the support frame other than the section serving as the pivot axle.

Abstract: A ski binding part with a sole holder for ski boots, which can be automatically adjusted to provide the proper hold-down force for different height ski boot soles or ski boot heels by a torque limiting coupling and a bolt which, when the ski binding is mounted on the ski, stands substantially perpendicular with respect to the upper side of the ski.

Abstract: A safety ski binding having a pair of sole holders pivotally secured to a base plate. Structure is provided for damping the movement of the sole holders to the ski boot releasing position. The damping mechanism includes a chamber having a fluid therein and a member movable in the chamber. The movable member in the chamber is connected through linkage to the sole holders and moves in response to a movement of the sole holders. The fluid on one side of the movable member will flow in a restricted manner to the other side thereof in response to sudden movements of the sole holders. The initial movement of the movable member is, therefore, restricted due to the fact that the fluid on the aforesaid one side of the movable member is restricted in its flow to the other side.

Abstract: A ski brake has a base plate secured to the upper side of a ski which pivotally supports a braking arm carrier for movement between a braking position and a retracted position about a first axis normal to the longitudinal axis of the ski. Two wire braking arms are pivotally supported in the braking arm carrier, each braking arm having a free end which is spaced from the braking arm carrier and from the pivot axis of the braking arm. Means are provided for pivoting the braking arms as the braking arm carrier pivots between braking and retracted positions, and springs urge the braking arm carrier toward the braking position. A first member is supported on the base plate for pivotal movement about a second axis, and a second member is pivotally connected at opposite ends to the first member and to the braking arm carrier at the ends thereof remote from the second and first axes, respectively. The second member and braking arm carrier define a toggle-joint.

Abstract: A structure for securing one end of a safety strap to a ski or to a component fixedly mounted on the ski. The other end of the safety strap is presumed to be secured to the skier by any conventional means. The structure by which the safety strap is secured to the ski structure enables the strap to hold the ski to the skier should the ski become disconnected from the skier while travelling on a chairlift or at slow speeds. However, this same structure will facilitate a release of the strap from engagement with the ski structure should the ski be pulled away from the skier with a sufficient magnitude of force, such as will occur during falls at high speeds. The thereafter released ski will be stopped by, for example, a ski brake mechanism mounted on the ski.

Abstract: A front jaw or a rear jaw for use in a ski binding arrangement. The jaw utilizes a support member which has a ski boot sole engaging structure for releasably holding the ski boot onto the ski. The ski boot holding structure facilitates a movement of the ski boot relative to the ski during a release operation in both the horizontal and vertical directions as well as solely in the vertical direction and solely in the horizontal direction. The support member supporting the ski boot holding members is guided for movement in a direction parallel to the longitudinal axis of the ski and is urged into engagement with the ski boot by a spring which is separate from the release spring.
