Abstract: A ski brake for preventing the runaway of a ski. A pair of brake legs are pivotally mounted at each side of the ski for alternately occupying an inactive position alongside of and parallel with the ski or an active position projecting downwardly from the ski. A generally U-shaped member is connected to the brake legs and lies against the upper surface of the ski and under the ski boot when the latter is in position on the ski. The U-shaped member is so arranged as to be subjected to tension when pressed down against the ski by the ski boot with such tension being relieved when same is permitted by removal of the ski boot to spring up away from the ski and to move the brake legs into the abovementioned active position. A stepping plate and a lever are pivotally connected to each other and cooperate with the U-shaped member to effect the aforementioned movement toward the ski when the ski boot is placed in position on the ski between the ski bindings.

Abstract: A ski brake for skis utilizing a spring construction such as is illustrated in U.S. Pat. No. 4,014,563. The spring is composed of a U-shaped portion having a pair of generally parallel legs and a connecting cross-part. The heel holder of a ski binding has a projection thereon which cooperates with the U-shaped part to effectively hold down the ski brake in the cocked or ready position without requiring a direct engagement of the ski boot with the U-shaped part.

The locking member engages a holding member and the sole plate is secured adjacent its frontmost end against a vertical movement relative to the ski. In addition, the sole plate is pivotal approximately in the center thereof about a vertical axis which is fixed relative to the ski. The locking member engages a flange which cooperates with a locking element in overlapping relationship with the holder. The holder is supported for movement about a universal type joint.

Abstract: A buckle device for a safety strap for use with skis. The buckle device is comprised of a housing having a cavity therein and a slotlike opening providing communication to the cavity. The upper wall of the cavity is defined by a resilient tab having a push button or the like thereon to facilitate a flexing of the tab downwardly into the cavity. A catch part having generally the thickness corresponding to the width of the slotlike opening in the housing is adapted to be slid through the slotlike opening in the housing so that the free end of the catch part becomes positioned within the cavity in the housing. The catch part has a flexible tab thereon forming a barb or hook which, upon entry into the cavity, will engage a projection in the cavity to prevent a removal of the catch part from the cavity. A depressing of the push button will effect an engagement between the upper wall of the cavity and the barb or hook to locate the barb or hook in alignment with the slotlike opening.

Abstract: A safety ski binding having a base and a sole holder pivotally connected to the base and movable about a pivot axis between a position of use and a release position. An adjustable abutment and a holding member are provided on the base. A slide member is reciprocally slidably movably mounted on the base and has an inclined surface thereon. The slide member is movable toward and away from the holding element. A single spring is provided and engages and extends between the slide member and the adjustable abutment for urging the slide member toward the holding member on the base. A locking pin is secured to the sole holder and is positioned to engage the holding element and the inclined surface at a location spaced from a threshold part when the sole holder is in the position of use.

Abstract: Manual release means for safety ski binding. The sole holder for the forward or rearward end of a ski boot is pivoted to a housing and includes a pin within said housing which moves upwardly and downwardly with opening and closing movement of the sole holder. A pair of tonglike means resiliently embrace said pin for normally holding the sole holder in sole engaging position but are spread apart against an adjustable spring force upon imposition of a predetermined opening force onto the sole engaging means of the device. One side of said tonglike device is directly engaged by one end of the adjusting spring and the other side of said tonglike device is engaged by the reaction means holding the other end of said spring whereby to double the holding strength of the tonglike means for a given spring as compared to a construction in which the spring holds only one side of a pin retaining device.

Abstract: A device for mounting a binding component onto a ski and providing for longitudinal adjustment thereof on and with respect to the ski. A carriage for carrying the binding component is arranged for slidable adjustment along a ski. Either the carriage or a device fixed to the ski carry a toothed rail and the other thereof carries a toothed locator positioned for crosswise motion relative to the ski into and out of engagement with the toothed rail. A light spring holds the locator in normal engagement with the toothed rail. A manual device is provided for disengagement of the parts upon moving of the locator crosswise of the ski against the spring. This enables the spring to be relatively light inasmuch as it functions only to hold the locator in rail engaging position and the locator may be easily disengaged by simply direct movement thereof against the spring.

Abstract: Run-away preventing device for skis. A pair of prongs are pivotally mounted at each side of a ski for alternately occupying an inactive position alongside of and parallel with the ski or an active position projecting downwardly from the ski. A generally U-shaped member is connected to said prongs and lies against the upper surface of the ski and under the ski boot when the latter is in position on the ski. Said U-shaped member is so arranged as to be subjected to tension when pressed down against the ski by the ski boot with such tension being relieved when same is permitted by removal of the ski boot to spring up away from the ski and move said prongs into the above-mentioned active position. Said generally U-shaped member and the prongs connected thereto comprise only a single movable part and hence combine a minimum of parts with a maximum of reliability.

Abstract: Sole holder component for a ski binding. A vertically movable sole holder is provided with a row of vertically arranged ratchet teeth and is spring biased into its upward position. At least one sidewardly movable slide is engageable with said ratchet teeth for holding same against upward movement and said slide is spring biased into such engaged position. Means manually operable are provided for manual withdrawal of said slide and consequent release of said sole holder when desired.

Abstract: A tension adjustment device for a safety ski binding. A device is provided by which the tension on a safety ski binding may be selected and determined without the necessity of a ski boot being present in the binding. There is provided a two-part carriage movable longitudinally of the ski and capable of being fixed at a selected point on the ski. The two parts of said carriage are movable together in one direction due to a manually applied force and are movable relative to each other in the opposite direction against a spring force by a manually operable adjustment device such as an eccentric or through the application of a force to the ski binding carrying part. One of the parts is mounted onto a ski supported base plate and the other of said parts carries the ski binding. With the ski binding free of engagement with the ski boot the adjustment device is operated to select the desired tension for the binding.

Abstract: For the heel holder of a safety ski binding having a separable sole plate, there is provided a row of teeth laterally across the sole plate and anchoring means for anchoring a cable extending from said means to the component engaging the heel of the ski boot. Said anchoring means comprises a pair of longitudinally spaced cross members which are connected together and which provide a fulcrum intermediate the ends thereof for engaging said sole plate. Said cable is anchored to said anchoring means on one side of said fulcrum and tooth means are provided on the other side thereof for engaging the teeth on the sole plate. The force of the cable when in operating position with respect to a ski boot holds the tooth firmly in engaging position but with the ski boot removed the anchoring means may be tilted and quickly and easily adjusted to any different desired position.

Abstract: A safety ski binding having a sole plate releasably secured to a ski between a pair of holding parts. The sole plate includes a toe gripping device for gripping over the toe of a ski boot and, in addition, a heel holding device adjustable in the longitudinal direction for holding the heel of the ski boot to the sole plate. The heel holding device is connected to a carriage member which is composed of two parts, both movable relative to the other. One of the parts is fixable by a locking device in several positions on the sole plate to fix the carriage member relative to the sole plate.

Abstract: Adjusting mechanism for fastening a ski boot to a sole plate. In such a device there is provided a device for gripping one end, normally the heel, of the ski boot and a ratchet for determining the position of the gripping device with respect to the remainder of the sole plate. Same is spring loaded for normal engagement and manually operable for release. The ratchet teeth are oriented for permitting free movement of the gripping device in one direction, normally toward the toe of the ski boot, and for normally holding same against movement away therefrom. In alternative embodiments, the ratchet teeth may be provided on guide rods, on the edges of dovetail guides, or on a re-entrant device entering into a recess in the sole plate structure.

Abstract: A low friction device for use between a ski boot sole and the upper surface of a ski to minimize friction upon the occurrence of a relative movement between the ski boot sole and the upper surface of the ski. A low friction material insert is secured to a mounting plate which is, in turn, secured to the upper surface of the ski. The low friction material projects above the upper surface of the mounting plate to effectively engage the bottom surface of the ski boot sole. The insert may be secured to the mounting plate in a number of ways but the important characteristic is that the structure by which the mounting plate is secured to the upper surface of the ski will effect a simultaneous securement of the insert to the mounting plate.
