A heel holder for a safety ski binding having a sole plate which is secured to the ski by a locking member which is movable against the force of a spring. 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.

Heel holder

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. Once this alignment has occurred, the catch part can be pulled from the cavity.

Buckle for safety strap for skis

A safety ski binding having a reinforcing member on a ski boot, which ski boot has a shaft portion which is pivotal about a transverse axis. The reinforcing member has a shoulder thereon which is engageable with a removable support to limit the backward pivoting movement of the shaft portion but permit a desired amount of frontward movement. A lever is provided which is movable into and out of supporting engagement with the shoulder to facilitate entry of the ski boot into the ski binding.

Safety ski binding

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. A movement of the sole holding part toward the release position will effect a movement of the locking pin past the threshold part against the urging of the single spring resisting the separation movement between the holding element and the inclined surface on the slide member.

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. Cam means manually operable by an external lever are placed between the sides of said tonglike means for manually releasing same as desired.

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. After adjustment of the carriage is completed, the locator may be caused to reengage with the toothed rail by releasing same to permit the spring to move the locator back to a position effecting such engagement.

Adjusting mechanism for ski bindings

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.

Run-away preventing device for skis

A guide plate assembly for use on skis in association with releasing ski bindings. The guide plate is composed of a mounting plate which is secured to the upper surface of a ski and has a low-friction material guide plate secured thereto and defining a support for the sole of a ski boot.

Guide plate for ski bindings

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. The two parts of the carriage are then moved together to enable the binding to engage the ski boot and again locked into position on the ski. The adjustment device is now released and the spring acting between the parts of the two-part carriage will cause the binding to bear against the ski boot with the desired pressure.

Device for ski bindings

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.

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. In one embodiment the transversely positioned teeth are on the top of the sole plate and in another embodiment the transversely positioned teeth are on the bottom of the sole plate.

A holding mechanism for holding ski boots onto a ski. The holding mechanism is comprised of a longitudinally extending rod extending parallel to the longitudinal axis of the sole of a ski boot and has at least one crossbar thereon with conventional elements for engaging and holding the boot to the crossbar. The longitudinal rod is secured at one of its ends to a holding element secured to the ski. The holding element restricts the longitudinal movement of the rod while simultaneously permitting lateral movements thereof. The longitudinal rod serves to rigidify the sole of the ski boot thereby making it possible for the ski boot to be made of a flexible material to improve the walking characteristics thereof.

Holding mechanism for ski boots

An improvement in a front jaw for a safety ski binding. A base plate and a base member are fixed together and have two axes thereon which are arranged perpendicularly to the base plate. Each axis pivotally supports a two-arm lever so that the longer lever arm engages the ski boot and the shorter lever arm engages a locking element which in turn engages a locking member movable against the force of a spring. The specific improvement is the utilization of a single locking member which is spring loaded and urged into engagement with a locking element. The locking element has a curved sector with differently inclined portions thereon so that as the curved sector moves relative to the locking element upon a swinging motion of the lever arms, the locking member will be moved against the spring resistance to a certain threshold point after which the lever arms will be permitted to move freely outwardly to facilitate a releasing function.

Front jaw for safety ski bindings

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.

A safety ski binding having a sole holder pivotally secured to a base member. The sole holder is held in condition of use by a locking member, which locking member is engaged by a locking part. The locking part is urged into engagement with the locking member by a spring. The locking part is guided in a limited manner in a guideway provided on a support part, which support part is pivotally secured to the base. The support part carries both the spring and a shaft on which the release lever is pivotally secured. The locking member has a notch and a recess therein, the locking part being urged into engagement with the notch while the ski binding is in the condition of use and in the recess when the ski binding is in the position to receive the ski boot therein.
