Heel-holder for a safety ski binding including a snap-in device

A heel-holder for a safety ski binding comprising:

• a base plate adapted to be mounted to the upper surface of a ski, a base plate including a raised pin at a first end and at least one extension at a second end thereof;
• a housing horizontally pivotable about the raised pin, the housing including a cross-in disposed outside an upper wall thereof;
• a sole-holder vertically pivotable about the cross-pin, the sole holder including a hollow portion forming a control cam on an upper wall of the hollow portion;
• a snap-in device for releasing the binding provided in the housing, the snap-in device comprising a snap-in rocker pivotably mounted in the housing about a pivot pin arranged parallel to the cross-pin and a control member pivotably mounted on the snap-in rocker and perpendicular to the pivot pin, the snap-in rocker including a horizontal bar and a vertical bar, the horizontal bar having a free end and a fixed end, the free end comprising a snap-in protrusion, the vertical bar having a free end a fixed end and a center point substantially midway therebetween, the control member being substantially U-shaped in configuration and including a pair of horizontal legs and a vertical leg joining the horizontal legs, the vertical leg including a longitudinal slot engaged by the center point of the snap-in rocker vertical bar such that the control member pivots about the center point of the vertical bar, the snap-in rocker engaging the control cam of the sole-holder and the control member engaging the at least one base plate extension;
• and
• a spring for loading the snap-in device, the spring being capable of applying a force for releasing the binding wherein the snap-in device reduces the spring force required for releasing the binding during both vertical pivoting of the sole-holder and horizontal pivoting of the housing.

A heel-holder for a safety ski binding comprising:

• a base plate adapted to be mounted to the upper surface of a ski, the base plate including a raised pin at a first end and a vertical stud at a second end thereof;
• a housing horizontally pivotable about the raised pin, the housing including a cross-pin disposed outside an upper wall thereof;
• a sole-holder vertically pivotable about the cross-pin, the sole holder including a hollow portion forming a control cam on an upper wall of the hollow portion;
• a snap-in device for releasing the binding provided in the housing, the snap-in device comprising a snap-in rocker pivotably mounted in the housing about a pivot pin arranged parallel to the cross-pin and a control member pivotably mounted on the snap-in rocker and perpendicular to the pivot pin, the control member being substantially U-shaped in configuration and including a pair of horizontal legs and a vertical leg, the snap-in rocker engaging the control cam of the sole-holder and the control member engaging the vertical stud of the base plate, wherein the vertical stud rests between the horizontal legs of the control member;
• and
• a spring for loading the snap-in device, the spring being capable of applying a force for releasing the binding wherein the snap-in device reduces the spring force required for releasing the binding during both vertical pivoting of the sole-holder and horizontal pivoting of the housing.

A heel-holder for a safety ski binding comprising:

• a base plate adapted to be mounted to the upper surface of a ski, the base plate including a raised pin at a first end and a plurality of vertical studs at a second end thereof;
• a housing horizontally pivotable about the raised pin, the housing including a cross pin disposed outside an upper wall thereof;
• a sole-holder vertically pivotable about the cross pin, the sole-holder including a hollow portion forming a control cam on an upper wall of the hollow portion;
• a snap-in device for releasing the binding, the snap-in device comprising a snap-in rocker pivotally mounted in the sole-holder about a pivot pin arranged parallel to the cross-pin and a control member pivotally mounted on the snap-in rocker and perpendicular to the pivot pin, the control member being substantially U-shaped in configuration and including a pair of horizontal legs and a vertical leg, the snap-in rocker engaging the control cam of the sole-holder and the control member engaging the vertical studs of the base plate at the outer peripheral surfaces of the horizontal legs of the control member;
• and
• a spring capable for loading the snap-in device, the spring being capable of applying a force for releasing the binding, wherein the snap-in device reduces the spring force required for releasing the binding during both the vertical pivoting of the sole-holder and the horizontal pivoting of the housing.
