Abstract
Abstract A releasable heel hold-down device is mounted on a ski so that a base part and a housing pivotally mounted on the base part extend in the longitudinal direction of the ski. A crank pivotally mounts the housing on the base part so that the crank pivots about a first axis on the base part and is pivotally connected to the housing about a second axis spaced forwardly of the first axis. Further, a journal extending laterally from the housing, is connected into an L-shaped slot in the base part and moves through the slot as the housing is displaced between a heel holddown position, a heel release position and a locked release position. The journal is spaced rearwardly from the first and second axes. In these different positions, the journal and the first and second axes define the corners of a triangle. In the hold-down position and the locked released position of the housing the connecting line between the second axis and the journal is located below the first axis, however, in the heel release position the first axis is located below the connecting line.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
387 words
A releasable heel hold-down device for a ski binding including a base part arranged to be mounted on a ski surface and to extend in the longitudinal direction of the ski, a housing extending in the longitudinal direction of the ski and having a first end arranged to be located adjacent the portion of the heel of a ski boot on the ski and a second end spaced rearwardly along the ski from the first end, a heel hold-down member secured to the first end of said housing, a crank extending in the longitudinal direction of the ski and pivotally connected to said base part about a first axis and to said housing about a second axis, the first and second axes of the pivotal connection of said crank being spaced apart in the longitudinal direction of the ski, an elongated adjustable spring mounted on one end on said crank at the end thereof closer to the first end of said housing and extending toward the second end of said housing, abutment means in said device located adjacent the second end of said housing for supporting the other end of said adjustable spring, means for displaceably mounting said housing relative to said base part, wherein the improvement comprises that said means for displaceably mounting said housing comprises an L-shaped slot in said base part and a journal attached to said housing and movably displaceable through said L-shaped slot, said L-shaped slot comprising a first leg extending generally in the longitudinal direction of the ski and a second leg extending downwardly from one end of said first leg and at an angle to the longitudinal direction of the ski, said L-shaped slot spaced in the longitudinal direction of the ski from said first and second axes, said first and second axes and said journal forming three corners of a triangle and said second axis and said journal defining the opposite ends of a connecting line, said housing being displaceable between a holding position for securing the heel of a ski boot on a ski, a release position for releasing the heel of the ski boot and a locked release position so that in the holding position and the locked release position said first axis is located above the connecting line extending between said second axis and said journal.
Claim 2
Dependent Claim
387 words
A releasable heel hold-down device for a ski binding including a base part arranged to be mounted on a ski surface and to extend in the longitudinal direction of the ski, a housing extending in the longitudinal direction of the ski and having a first end arranged to be located adjacent the portion of the heel of a ski boot on the ski and a second end spaced rearwardly along the ski from the first end, a heel hold-down member secured to the first end of said housing, a crank extending in the longitudinal direction of the ski and pivotally connected to said base part about a first axis and to said housing about a second axis, the first and second axes of the pivotal connection of said crank being spaced apart in the longitudinal direction of the ski, an elongated adjustable spring mounted on one end on said crank at the end thereof closer to the first end of said housing and extending toward the second end of said housing, abutment means in said device located adjacent the second end of said housing for supporting the other end of said adjustable spring, means for displaceably mounting said housing relative to said base part, wherein the improvement comprises that said means for displaceably mounting said housing comprises an L-shaped slot in said base part and a journal attached to said housing and movably displaceable through said L-shaped slot, said L-shaped slot comprising a first leg extending generally in the longitudinal direction of the ski and a second leg extending downwardly from one end of said first leg and at an angle to the longitudinal direction of the ski, said L-shaped slot spaced in the longitudinal direction of the ski from said first and second axes, said first and second axes and said journal forming three corners of a triangle and said second axis and said journal defining the opposite ends of a connecting line, said housing being displaceable between a holding position for securing the heel of a ski boot on a ski, a release position for releasing the heel of the ski boot and a locked release position so that in the holding position and the locked release position said first axis is located above the connecting line extending between said second axis and said journal.
Claim 3
Dependent Claim
69 words
A releasable heel hold-down device, as set forth in claim 1, wherein said journal is located in said first leg of said slot when said first axis is located above the connecting line between said second axis and said journal and in the release position of said housing said first axis is located below the connecting line and said journal is located in said second leg of said slot.
Claim 4
Dependent Claim
59 words
A releasable heel hold-down device, as set forth in claim 2, wherein said second leg of said slot extends substantially perpendicularly to said first leg of said slot and the wall of said second leg closer to the second end of said housing serves as a locking support for said journal in the locked release position of said housing.
Claim 5
Dependent Claim
58 words
A releasable heel hold-down device, as set forth in claim 1, wherein the perpendicular distance of the first axis from the connecting line between the second axis and said journal in the holding position of said housing is greater than the perpendicular distance of said first axis from said connecting line in the release position of said housing.
Claim 6
Dependent Claim
63 words
A releasable heel hold-down device, as set forth in claim 1, wherein a support connects one end of said spring on said crank adjacent the first end of said housing and a support is located at the opposite end of said spring adjacent the second end of said housing and said support is mounted on one of said housing and said base part.
Claim 7
Dependent Claim
50 words
A releasable heel hold-down device, as set forth in claim 5, wherein said support for said spring mounted on said crank is located in the holding position of said housing above said first and second axes and forwardly of said first axis relative to the first end of said housing.
Claim 8
Dependent Claim
62 words
a releasable heel hold-down device, as set forth in claim 1, wherein said crank forms an elongated lever extending from adjacent the first end of said housing to a position rearwardly of the second end of said housing so that the end of said crank projecting from the second end of said housing can be operated for releasing the heel hold-down member.
Claim 9
Dependent Claim
157 words
A releasable heel hold-down device, as set forth in claim 1, wherein a two-arm lever is pivotally mounted on said base part for rotation about a third axis extending transversely of the longitudinal direction of said housing and located between the first end of said housing and said journal thereon, said lever having a first lever arm extending forwardly from said third axis to a position projecting outwardly from the first end of said housing and forming a heel plate and a second arm extending in the opposite direction from said third axis relative to said first lever arm and arranged below said journal so that in the released position of said housing when a downward force is exerted on the forward end of said first lever arm said second lever arm is pivoted upwardly about said third axis for displacing said journal from the second leg of said slot into the first leg of said slot.
