Abstract
A releasable ski binding is provided with a boot holder which can be swivelled around a vertical shaft and is pushed into a normal ski boot holding position by a piston. At its end facing the boot holder, the piston is arranged to be slidable into the transverse direction with play, and at its other end, the piston is arranged to be slidable in a guide almost without play. Thus, swivel motions of the boot holder can take place largely without friction between the boot holder and the piston parts which rest against it. At the same time, the normal position is defined virtually without play.
Claims23
A releasable ski binding comprising:
- a boot holder part clampingly engageable with a ski boot or ski boot sole holder,
- a vertical pivot mount for mounting the boot holder part at a ski and for permitting swivelling movement of the boot holder part about a vertical pivot axis between a normal skiing position clampingly holding the ski boot and a release position permitting release of the ski boot,
- a piston abuttingly engageable with the boot holder part to resist movement of the boot holder part from the normal skiing position while permitting such movement in response to a predetermined force from the boot holder part during swivelling movement thereof,
- and a guide surface arrangement for guiding movement of the piston during swivelling movement of the boot holder part, said guide surface arrangement including a first guide section with interengageable sliding surfaces for guiding the piston substantially without play in the transverse direction of the ski only in an area of the piston disposed away from its end area engageable with the boot holder part and a second guide section adjacent said end area which permits slight transverse movement of an area of the piston adjacent said end area during longitudinal movement of the piston when the boot holder part is swivelled toward its release position.

A releasable ski binding comprising:
- boot holder means clampingly engageable with a ski boot or ski boot sole holder,
- vertical pivot mount means for mounting the boot holder means at a ski and for permitting swivelling movement of the boot holder means about a vertical pivot axis between a normal skiing position clampingly holding the ski boot and a release position permitting release of the ski boot,
- piston means abuttingly engageable with the boot holder means to resist movement of the boot holder means from the normal skiing position while permitting such movement in response to a predetermined force from the boot holder means during swivelling movement thereof,
- and guide means engageable with the piston means for guiding movement of the piston means during swivelling movement of the boot holder means, said guide means including a first guide section for guiding the piston means substantially without play in the transverse direction of the ski only in an area of the piston means disposed away from its end area engageable with the boot holder means and a second guide section adjacent said end area which permits slight transverse movement of an area of the piston means adjacent said end areas during longitudinal movement of the piston means when the boot holder means is swivelled toward its release position,
- wherein the end of the piston means which is away from the boot holder means has a larger width in the transverse direction of the guide means than the other end of the piston means.

- wherein said piston means and boot holder means include respective interengageable means at first and second opposite sides of a longitudinal axis of a ski when the boot holder means is mounted in an in-use position on a ski, said interengageable means being configured such that the interengageable means at the first side of the longitudinal axis are disengaged from one another during pivotal movement of the boot holder means while the interengageable means at the second side remain in guiding contact with one another in a one-sided engagement,
- wherein a spring is provided for continuously biasing the piston means toward the boot holder means,
- wherein said interengageable means include respective recesses in the boot holder part and projections on the piston means,
- wherein the guide means are formed at a bore which is essentially open only at its boot holder means side end for accommodating the parts of the piston means that project out of the guide means and wherein the space between the guide means and the boot holder means is closed off by a bellows-type covering.
