Abstract: The invention concerns a ski safety binding with a sole plate pivoting about a rising pin. The sole plate cannot however be lifted off the ski. The sole plate includes at its rear a heel holder and at its front a toe piece. The sole holder is pivotable about a cross rod at the front. The toe piece includes a control member associated with a control cam of a guide plate. When a pre-determined pivot angle of the sole holder relative to the longitudinal ski axis is reached, the control cam allows the sole holder to pivot to allow the release of the ski boot. In the present invention the front of the sole plate is designed to be a bearing which supports at least one cross bolt which supports the sole holder, the control member and a ratchet lever. Further, at the front of the bearing is an attachment which enters a guide groove located in the guide plate and is moveable in longitudinally displaceable manner on a base plate.

Abstract: A binding for retaining a boot on a ski. The binding is provided with a jaw for retaining one end of a boot against the ski, and a support on which the jaw is mounted. The support itself is connected to two arms mounted on the ski. These two arms are separated by a distance less than the width of a sole of the boot which the binding retains on the ski.

Abstract: This safety ski binding includes a base plate adapted to be fastened to an upper side of the ski and supporting a vertical pivot. A sole plate is pivotably mounted on the vertical pivot and supports at its rear end a heel support having a sole support which is acted upon by a locking spring. The heel support includes a holding jaw at its front end. The sole plate is pushed by the locking spring in the direction of its central position.An additional release of the ski boot is provided by movement of the heel support relative to the sole plate, as in the case of a pure horizontal load. A heel support has a bearing block which is pivotable with its base about a vertical axial member. The vertical axial member of the bearing block is fastened to the sole plate. A further roller is allocated to the bearing block which is pressed by an additional spring against a cam disposed at the base plate.

Abstract: A ski binding adapted to releasably hold the front of a ski boot on a ski. The front of the boot includes front-end zone spaced from the lateral edges of the boot. The binding includes a jaw, a support, and a support zone means on the jaw. The jaw is adapted to hold the front of the boot and adapted to laterally pivot in response to pivoting of the boot. The support, which is positioned on the ski, includes two upwardly converging lines of support. The jaw is adapted to laterally pivot around either one of these upwardly converging jaw lines of support. The support zone means which is positioned on the jaw supports the front-end zone of the boot when the boot is held by the jaw. As a result, when the boot experiences a torsional force and a frontward force on the boot, the boot laterally pivots and the front of the boot is pressed downward against the ski and against the support zone means.

Abstract: A resilient mechanism for maintaining the jaw unit of a safety ski binding in the normal boot-retaining position includes two vertical flat faces extending transversely on a stationary jaw-unit support. Two flat cams applied against the flat faces by a single spring consist respectively of a bearing surface of the jaw-unit body and of a small bearing plate carried by a rod on which the jaw-unit body is slidably mounted. The rod is slidably mounted within a knuckle-bearing orifice of the stationary support and is thus capable of pivotal displacement with the jaw unit in all directions on the stationary support.

Abstract: A ski binding adapted to releasably hold the front of a ski boot on a ski. The front of the boot includes front-end zone spaced from the lateral edges of the boot. The binding includes a jaw, a support, and a support zone on the jaw. The jaw is adapted to hold the front of the boot and adapted to laterally pivot in response to pivoting of the boot. The support, which is mounted on the ski, includes two upwardly converging lines of support which converge at a convergence point. The jaw is adapted to laterally pivot around either one of these upwardly converging lines of support. The support zone which is positioned on the jaw supports the front-end zone of the boot when the boot is held by the jaw. The median vertical height of the support zone is substantially at the same vertical height as the convergence point.

Abstract: A safety ski binding provided with a sole plate supported pivotally on a ski-fixed pivot, however, is secured against lifting off from the ski carries at its rear end a heel holder and at its front end a front jaw. The front jaw is pivotal about a transverse axle and carries a control element extending in the longitudinal direction of the ski in the skiing position. On the front end of the control element is supported rotatably a roller, with which is associated a cam secured on the ski, which cam, upon reaching a predetermined angle of traverse of the sole plate relative to the longitudinal direction of the ski, permits a pivoting of the front jaw in the sense of a release of the ski shoe. In order to permit in such a ski binding a storing of the cam protected against dirt, the invention provides that the cam (2f) for the roller (15) of the control element (14) is stored in a housing (2,7) which is open only toward the tail end of the ski and serves to support the front jaw (10,17).

Abstract: A ski binding adapted to pivot both laterally and vertically. The binding includes a support attached to the ski and an assembly adapted to pivot therearound. The assembly includes a jaw, a pivoting element and an elastic system which biases the pivoting element and support into contact with each other. The pivoting element and the support form a lateral pivoting system having two projections and complementary grooves, each of which form a line of support around which the pivoting element and assembly may laterally pivot. The elastic system in one embodiment contacts the rear of the support. In another embodiment the elastic system contacts the rear of a rocker pivoting around the pivoting element, and contacting the rear of the support. Both the rear of the rocker and the rear of the support comprise a downwardly and rearwardly extending release incline and a downwardly and forwardly extending opening incline.

Abstract: A projecting nose from the grooved body is engaged in a stirrup to retain the boot on the ridge of a cross-country ski to which the stirrup is pivotally connected by an axis transverse to the ridge. An outer stirrup can be swung relative to the inner stirrup to cause a rod to rise in arcuate windows of the inner stirrup and thereby lift the nose of the boot and clamp it against the fixed crosspiece of the inner stirrup. A detent plate pivotal on an outer stirrup can releasably latch the outer stirrup relative to the inner stirrup.

Abstract: A ski binding includes a base plate adapted to be secured to a ski, a cover plate supported on the base plate for pivotal movement about a vertical axis, and an adjustable release arrangement for yieldably resisting pivotal movement of the cover plate in either direction away from an initial position. The release arrangement can be adjusted from a side of the binding. Front and rear holding mechanisms are provided on the cover plate and releasaly hold a ski shoe on the cover plate, the front holding mechanism including a pivotally supported holding jaw which is controlled by the adjustable release arrangement, and the rear holding mechanism being adapted to release only in response to an upward force component.

Abstract: A binding having a jaw is adapted to pivot laterally around two converging support lines on a support against the bias of an elastic mechanism. The binding also includes two lateral wings for receiving a front end of the boot, and a support zone positioned between the wings. The support zone is adapted to contact the front end zone of the boot along a line which intersects a transverse plane passing through the support lines above their convergence point. As a result, when a torsional fall is combined with a frontward fall, the torsional component of the fall causes the boot to apply lateral pressure to one of the wings, thereby providing a torque or moment on the jaw. The frontward component of the fall causes the boot to apply frontward pressure on the support zone, thereby increasing the torque experienced by the jaw in the direction of the torque resulting from the torsional component of the fall.

Abstract: A heel piece for a safety ski binding is provided comprising a support member in the form of a slide member on which is pivotally mounted a sole holder having a pedal, a sole engaging portion and an interior cam surface configured to cooperate with a bearing member or cam follower which engages the cam surface. The cam follower is supported by a bearing lever having an axis of rotation near the upper surface of the ski, and a connecting member. The cam surface has an upper portion, a lower portion and an intermediate critical portion, and the binding opens when the soleholder is driven upwardly so that the critical portion passes the cam follower. An opening lever for manually opening the binding is rotatably attached to the connecting member, and is pivotally mounted on the soleholder.

Abstract: A ski binding adapted to releasably hold the front of a ski boot on a ski. The front of the boot includes front-end zone spaced from the lateral edges of the boot. The binding includes a jaw, a support, and a support zone on the jaw. The jaw is adapted to hold the front of the boot and adapted to laterally pivot in response to pivoting of the boot. The support, which is positioned on the ski, includes two upwardly converging lines of support. The jaw is adapted to laterally pivot around either one of these upwardly converging jaw lines of support. The support zone which is positioned on the jaw supports the front-end zone of the boot when the boot is held by the jaw. As a result, when the boot experiences a torsional force and a frontward force on the boot, the boot laterally pivots and the front of the boot is pressed downward against the ski and against the support zone means.

The assembly includes a jaw, a pivoting element and an elastic system. The support has a substantially flat surface biased into contact with a substantially flat surface on the pivoting element. The pivoting element pivots around a single vertical axis intersecting the longitudinal axis of the binding. The elastic system in one embodiment contacts the rear of the support. In another embodiment the elastic system contacts the rear of a rocker pivoting around the pivoting element, and contacting the rear of the support. Both the rear of the rocker and the rear of the support comprise a downwardly and rearwardly extending release incline and a downwardly and forwardly extending opening incline. The elastic system is compressed when it pivots vertically along the release incline, so as to bias the assembly toward its centered boot retaining position.

Abstract: A safety ski binding includes a releasable jaw having a pivotally supported holding mechanism which is adapted to engage a ski shoe. The jaw includes first and second cylinders with fluid actuated pistons therein, and a fluid channel interconnects the cylinders. A check valve in the fluid channel resists fluid flow from the first cylinder to the second, and a solenoid controlled valve in the fluid channel, when open, creates a bypass around the check valve. A mechanism is provided for applying forces to the piston of the second cylinder to pressurize the first cylinder via the check valve causing the piston of the first cylinder to itself be urged against or to urge another member against a locking track in a manner which maintains the jaw in a closed position. In a preferred embodiment, the cylinders are provided on the holding mechanism and the locking track is fixed to the ski.

Abstract: A safety ski binding releasably holding a boot on a ski. The binding includes a jaw adapted to hold the boot and to pivot laterally, and an elastic mechanism biasing the jaw against lateral pivoting. When vertical stress acts on the binding, friction is generated which further biases the jaw against lateral pivoting, thereby preventing lateral release of the boot when dangerous lateral stress acts on the boot. To counteract this friction, a compensation mechanism is provided which counteracts the increased biasing against lateral pivoting both in the event upward vertical stresses act on the boot and in the event downward vertical stresses act on the boot. In one embodiment the compensation mechanism includes a pair of toggles which reduce the bias of the elastic mechanism in response to the upward pivoting of the jaw so that a constant bias against lateral pivoting is maintained on the jaw when vertical stress acts on the binding.

Abstract: A safety ski binding part includes a base plate having a roller supported thereon for rotation about a generally longitudinally extending axis, and a sole holder supported on the base plate for pivotal movement around a vertical axis and a transverse horizontal axis, the sole holder having a shoulder thereon. A lever supported on the base plate for pivotal movement about a transverse axis has a nose engageable with the shoulder and a transversely extending cam surface engageable with the roller. A release spring biases the lever in a direction urging the nose into engagement with the shoulder and urging the cam into engagement with the roller.

Abstract: A heel holder includes a base plate mountable on the ski, a sole holder supported for vertical and transverse horizontal movement relative to the base plate, a first locking mechanism for yieldably resisting upward movement of the sole holder away from a closed position adjacent the base plate, and a second locking mechanism which prevents transverse horizontal movement of the sole holder until it has moved upwardly a predetermined distance away from the base plate. The second locking mechanism includes cooperating locking parts on the base plate and the sole holder, one locking part being vertically movably supported on the associated one of the base plate and sole holder and being resiliently urged toward the other locking part. One of the locking parts has a vertical recess which receives the other locking part in the closed position of the sole holder.

Abstract: A laterally releasable toe unit has two laterally pivotable side jaws (11) which are held in a ski boot retaining position by a yoke (26) on which a release spring (30) acts and which can be pivoted laterally while pushing the yoke rearwardly against the spring force to release the ski boot. A toe plate (15) which is movable by a small amount in a vertical direction is arranged behind a laterally fixed toe restrainer (13) and generates, via a force deflection transmission, a longitudinal force which is dependent on the contact force which acts on the toe and which counteracts the spring force via a bar member (12). At least one lever (14) which is acted on by the vertically displaceably or pivotably arranged toe restrainer (13) acts on the same bar member (12) in the same sense with a release force which is dependent on the vertically upwardly directed force acting on the toe restrainer (13).

Abstract: Safety ski binding for use in both downhill and cross-country skiing. A conventional 3-pin 75 mm. toe binding is mounted on a front base plate which is rotatable during downhill skiing, but is locked against rotation for cross-country skiing. The rear binding assembly employs a reversed Cubco toe binding used as a heel binding, which is locked to a heel latch assembly during downhill skiing, the heel latch being unlocked during cross-country skiing. In downhill skiing a safety release occurs by overcoming the spring compression of the Cubco binding, and such release is facilitated by the rotation of the ski boot about the axis of the front base plate. During cross-country skiing the heel latch is unlocked, and the heel of the ski boot is free to move vertically above the ski.

Abstract: A heel holder includes a sole holder which is supported for pivotal movement about a horizontal axis on a support member and has a control surface. A locking lever pivotally supported on the support member has a nose engageable with the sole holder control surface. A spring housing having a release spring therein is pivotal about the sole holder pivot axis, and a slide member movably supported in the spring housing is biased by the release spring against a side of the lever opposite the nose thereof when the spring housing is in an initial position. A centering spring is cooperable with the spring housing and with the sole holder or the support member and, after pivotal movement of the spring housing away from its initial position, urges the spring housing back toward such position.

Abstract: A spindle extending transversely to the longitudinal direction of a ski and parallel to the upper surface of the ski carries sole holder elements normally engaged against a ski boot to hold the ski boot on the ski. The spindle is disposed below the plane of the ski boot sole. If the ski boot exerts force in excess of a predetermined force against the sole holder elements either longitudinally or laterally of the ski, the sole holder elements swing forward about the axis of the spindle to below the plane of the ski boot sole to permit unimpeded movement of the boot. The spindle and the sole holder elements carried thereby are mounted on the ski for movement in a direction transversely of the ski. Release mechanism automatically permits the forward swinging movement of the sole holder elements when the spindle and sole holder elements have moved transversely of the ski a predetermined distance.

Abstract: A safety binding for use with a ski including holding support and intermediate members, and an elastic system. The holding member is adapted to hold one end of a ski boot onto the ski, and the support member is adapted to be attached to the ski.

In addition, the holding and intermediate members are adapted to pivot together with respect to the support member with substantially no relative movement between the holding and intermediate members against the bias of the elastic system for release of the boot.

Abstract: A heel holder of a ski binding includes a base plate supported on a ski, a housing pivotally supported on the base plate, and a release lever pivotally supported on the housing by a horizontal axle. The release lever has a cam and a locking member movably supported in the housing is urged against the cam by a release spring. A connecting member has a slotlike opening in one end through which a transverse axle provided on the release handle extends. A unit having a stepping spur and sole hold-down is pivotally supported on the opposite end of the connecting member. A compression spring disposed in a blind hole in the release lever and cooperable with the first end of the connecting member urges it outwardly, and torsion springs provided on the transverse axle urge the unit to swing upwardly.

Abstract: A front jaw for a safety ski binding includes a support member mounted on a ski having a hold-down cooperable with a ski shoe sole supported for vertical movement, a pair of centering levers cooperable with the sides of the ski shoe sole supported for pivotal movement about vertical axes, and a compensating lever supported for pivotal movement about a substantially horizontal axis. One end of the compensating lever engages the top of the sole hold-down and the other end engages the centering levers. A spring urges the centering levers inwardly, and the centering levers in turn urge the compensating lever pivotally so that it urges the hold-down downwardly. When the sole hold-down is moved upwardly during a fall, it causes pivotal movement of the compensating lever which in turn causes pivotal movement of the centering levers outwardly away from the ski shoe sole against the force of the spring. Upward movement of the sole hold-down is limited by a stop.

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.

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 safety binding of the "compensating" type having a binding unit moud on a vertical pivot and a boot-retention arrangement including laterally operable jaws and a vertically movable retention element. A spring-loaded locking system opposes vertical and lateral retention forces, respectively, upon vertical and lateral displacement of the boot. The compensating system, which acts against the spring load, causes the lateral and vertical retention forces to vary inversely with one another.

Abstract: A ski binding, either a toe clamp or a heel clamp, which is provided with clamping arm rotatably supported by a post fitted on the top surface of a ski, the post having a pendulum to face a hungover end of the clamping arm which is urged toward the boot by a mild elastic member. A marginal clearance is provided between the end of the pendulum and the hungover end of the clamping arm, whereby the clamping arm is locked by the pendulum and keeps clamping the boot onto the ski under normal use of the skis, but the clamping arm is not locked by the pendulum and allows the ski boot to be readily disengaged from the ski under an abnormal condition, such as fall, which causes the pendulum to be out of the lock position. A modification of this generic configuration is possible, which gives elasticity to the clamping arm by means of a second, stronger elastic member. Use of plural pieces of the generic or modified clamping unit improves the function and provides a variety in performance.

Abstract: A ski stop is associated with a heel tightener for safety ski bindings that comprises a boot heel-supporting turntable to which there are pivotably secured two pull members, one passing each side of the boot heel, which carry a sole retainer movable against the force of at least one spring. To permit stepping into the binding without prior manipulation and automatically bring the ski stop to a position ready for operation, a base plate fixed to the ski and carrying the turntable has a horizontal cross-shaft to which there is pivoted a pedal of the ski stop that is pivotable against the force of at least one spring to a position above the turntable at least approximately parallel to the base plate. At least one lever in the form of a braking skid is hinged to the pedal parallel to its pivotal shaft and the arm of the lever is guided for longitudinal movement in an eyelet 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.
