Abstract: A device to mount a release binding on a ski has a pair of blocks which are independent of one another. The blocks are mounted on the upper surface of a ski and the bindings are mounted on the pair of blocks. A connector connects the pair of blocks. The connector is inextensible and is mounted on the pair of blocks such that when the ski is flexed the connector prohibits the spreading of the pair of blocks while permitting the pair of blocks to approach toward one another.

Abstract: A ski boot fastening device includes at least one front and one rear engagement member for a boot which are adapted to be attached to a ski. Independent adjustment members of the two engagement members are provided on at least one of the front and rear engagement members or on the ski. This allows the skier to achieve, by an intervention located in a specific point, an independent adjustment of the two members for the engagement of the boot.

Abstract: A ski binding including a toe unit which is fixed to the ski and is provided with an adjustable spring acting on the toe unit safety release member. The binding also has a plate which extends longitudinally along the ski and is associated, at one end, with the toe unit safety release member and, at its other end, with a sliding body which supports the jaw. A rear spring is interposed between the sliding body and the plate in order to keep constant the center distance set between the toe unit and the heel unit, when the ski flexes.

Abstract: The ski fastening includes a pivoting toe locking element which provides a first toe holding down locking force by means of a first spring and a rear heel locking element which provides a second heel holding down locking force by means of a second spring. Both the first spring and the second spring are housed in the heel holding device and both the locking forces provided by such springs are simultaneously adjustable upon the activation of a single screw element also provided on the heel holding device. The heel holding device furthermore includes a first body connectable to a ski in an adjustable position and a second body which is slidably supported by the first body in a direction parallel to the longitudinal extension of the ski to thereby maintain a constant distance between the heel holding device and the toe holding device of the fastening even during flexing of the ski during use.

Abstract: A binding assembly for a structure which is designed to facilitate rapid movement along the surface of the earth such as a ski board for water wherein the binding assembly includes an elastic cord which when stretched permits tightening of the binding assembly to thereby securely clamp the user's foot to the structure. Once the binding assembly has been adjusted to the desired amount of securement, release of the elastic cord results in the binding assembly remaining in that established level of securement.

Abstract: A snowshoe is provided with a transverse steel cable that engages the opposite longitudinal side members of its frame structure. A harness secured to this cable consists of two jaw members which are pivotally connected to one another at one end thereof and cooperate to clamp the edge of the front sole portion of a user's boot. A rubber strap is attached at its opposite ends to one of the jaw members for further securing the boot to the harness. The decking of the snowshoe has an opening to allow the pivotal movement of the front portion of the boot during use. The jaw members have finger-engaging portions to facilitate the mounting and dismounting of a boot to and from the harness.

Abstract: The present invention relates to a safety binding of a boot on a ski which comprises two lateral jaws (2) mounted for movement under the force of an elastic member (5) between a closed service position in which these jaws coact with the sole of the boot (C) and an open position. It also comprises structure (3) interacting with the heel of the ski boot and having a sole grip member (29) mounted for movement by the force of the same elastic member between a service position in which this member maintains the rear end of the sole of the boot on the ski and an open position, the whole being so arranged that the opening or the closing of the lateral jaws effects the opening or the closing respectively of the sole grip member, and vice versa.

Abstract: A release ski binding having a sole plate which in its center area can be pivoted about an approximately vertical axis and can be tilted up about a transverse axis arranged in front of the vertical axis, which sole plate is held on the ski in the skiing position by a resilient holding mechanism, which holding mechanism is responsive to a swivelling movement of the sole plate relative to the ski and, upon reaching a predetermined angle of traverse, effects both an upwardly and also a side opening of a locking mechanism which secures the shoe on the sole plate, and which locking mechanism consists of at least one heel holder pivotal about a transversely extending axis.

Abstract: A safety ski binding having a base plate secured to a ski and a push rod movably mounted on the base plate and adapted to be displaceable against spring force along the axis of symmetry of the base plate. The axis of symmetry extends in the longitudinal direction of the ski. The push rod is adapted to be held in position by a tensioning device. A pair of rollers is carried by the push rod and the base plate, one roller being movable toward and away from the other roller. The axles of the rollers extend transversely to the longitudinal axis of the push rod and parallel to the base plate. The bottom of the heel portion of the ski boot has a longitudinally extending groove therein. The upper surface of the base plate has in the central portion thereon an upstanding truncated cone adapted to be received in the groove in the heel of the ski boot.

Abstract: Two sole clips are mounted on rods received in guide sleeves extending longitudinally of a ski, which guide sleeves are pivoted for swinging relative to the ski. A spring resists swinging of the sleeves relative to the ski, and another spring resists forward reciprocation of the rods in the guide sleeves. Under overstress conditions between a ski boot and the ski, the forward force on the sole clips will slide the rods forward in the guide sleeves and swivel one of the sole clips relative to its guide sleeve to release such clip from the boot sole for automatically freeing the boot from the ski.

Abstract: The system includes: a reference point on the ski; front and rear jaws for maintaining the boot on the ski and disposed in a predetermined relationship relative to this reference point; a member fixed on the ski and adapted to receive each jaw in a slidable manner and including means for guiding the jaws longitudinally; an inversed drive mechanism connecting the jaws and acting along the longitudinal axis of the ski for moving simultaneously the jaws in opposite directions from and towards the reference point on the ski; and single control means operating the inverse drive mechanism.

Abstract: Safety ski binding apparatus including a ski plate fixedly securable to a ski, a boot plate detachably securable to a ski boot by way of securing means, resilient connecting means connecting the ski and boot plates to one another while permitting relative movement of said plates about a plurality of mutually perpendicular axes, and signal means interposed for producing a single signal representative of relative movement of the plates, which signal effects release of the ski boot from the boot plate in response to a critical predetermined movement of said plates relative to one another.
