Abstract
The invention relates to an assembly of a boot and a retention element of the ski boot. The boot has at the level of its tip a local asymmetry, that the retention element has a specific and symmetrical elastic retention element adapted to cooperate with the asymmetric zone in a manner such that the boot is freed more easily on one side than on the other. The invention relates also to a retention element and a boot considered alone, and to a pair of boots whose tips are symmetrical to one another.
Claims26
An assembly of a boot and a retention device for a boot on a gliding board, said assembly comprising:
- a boot comprising an end having a tip extending on each side of a longitudinal vertical median plane of said boot, said tip having a local asymmetrical portion;
- a retention device adapted to be affixed to the gliding board, said retention device comprising:
- a retention jaw having a construction adapted to engage said tip of said boot in a retention position in alignment with a longitudinal vertical median plane of said retention device;
- a return spring operatively connected to said retention jaw to bias said jaw to said retention position, said jaw being supported for movement from said retention position against a return force of said return spring in response to movement of said tip of said boot laterally in a direction toward one or the other side of said longitudinal vertical median plane of said retention device from said retention position of said jaw to a release position upon a force exerted by said tip of said boot equal to or greater than a release threshold force;
- a symmetric elastic retention mechanism adapted to cooperate with said local asymmetric portion of said boot for causing said release threshold force to have an increased magnitude for release of said boot upon lateral movement in a direction toward said one side of said longitudinal vertical median plane of said retention device with respect to a direction toward said other side of said longitudinal vertical median plane of said retention device.
A retention device for use with a boot on a gliding board, the boot having an end with a tip extending on each side of a longitudinal vertical median plane of said boot, said tip having a local asymmetrical portion, said retention device comprising:
- a retention jaw having a construction adapted to engage the tip of the boot in a retention position in alignment with a longitudinal vertical median plane of said retention device;
- a return spring operatively connected to said retention jaw to bias said jaw to said retention position, said jaw being supported for movement from said retention position against a return force of said return spring in response to movement of the tip of the boot laterally in a direction toward one or the other side of said longitudinal vertical median plane of said retention device from said retention position of said jaw to a release position upon a force exerted by the tip of the boot equal to or greater than a release threshold force;
- a symmetric elastic retention mechanism adapted to cooperate with the local asymmetric portion of the boot for causing said release threshold force to have an increased magnitude for release of the boot upon lateral movement in a direction toward said one side of said longitudinal vertical median plane of said retention device with respect to a direction toward said other side of said longitudinal vertical median plane of said retention device.
A boot for use with a retention device on a gliding board, the retention device having a retention jaw with a construction adapted to engage a tip of and end of the boot in a retention position in alignment with a longitudinal vertical median plane of the retention device, and a return spring operatively connected to the retention jaw to bias the jaw to the retention position, the jaw being supported for movement from the retention position against a return force of the return spring in response to movement of the tip of the boot laterally to one or the other side of the longitudinal vertical median plane of the retention device from the retention position of the jaw to a release position upon a bias exerted by the tip of the boot equal to or greater than a release threshold force, said boot comprising:
- said end having said tip, said tip extending on each side of a longitudinal vertical median plane of said boot;
- and
- said tip having a local asymmetrical portion.
