Abstract
Abstract An improved ski binding assembly includes front and rear magnetic coupling units which are attachable to a ski and boot attachments which coact with the coupling units to hold the boot to the ski. Each coupling unit comprises means for providing an adjustable magnetic field as well as means for providing adjustable pressure relief. The boot attachments include a magnetically sensitive material so that when the ski boot is secured between the units the magnetic field provided by each unit will couple the unit and the adjacent boot attachment as a result of magnetic attraction.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
169 words
A ski binding unit for binding a ski to a ski boot that is equipped with magnetically conductive means, said unit comprising: a housing having first and second ends and means for attaching said housing to said ski so that said first and second ends are aligned lengthwise of said ski; two magnetically conductive pole pieces disposed within and mounted to said housing so that an end surface of each pole piece projects out of said first end of said housing for engagement by said ski boot; a permanent magnet disposed within said housing between and proximate to said pole pieces so as to induce a magnetic field in said pole pieces for magnetically binding said magnetically conductive means to said pole piece end surfaces; said magnet being movable relative to said housing and said pole pieces so as to permit adjustment of the intensity of the magnetic field at said pole piece end surfaces; and means for moving said magnet relative to said housing and said pole pieces.
Claim 2
Dependent Claim
169 words
A ski binding unit for binding a ski to a ski boot that is equipped with magnetically conductive means, said unit comprising: a housing having first and second ends and means for attaching said housing to said ski so that said first and second ends are aligned lengthwise of said ski; two magnetically conductive pole pieces disposed within and mounted to said housing so that an end surface of each pole piece projects out of said first end of said housing for engagement by said ski boot; a permanent magnet disposed within said housing between and proximate to said pole pieces so as to induce a magnetic field in said pole pieces for magnetically binding said magnetically conductive means to said pole piece end surfaces; said magnet being movable relative to said housing and said pole pieces so as to permit adjustment of the intensity of the magnetic field at said pole piece end surfaces; and means for moving said magnet relative to said housing and said pole pieces.
Claim 3
Dependent Claim
15 words
A unit according to claim 1 wherein said housing is made of a non-magnetic material.
Claim 4
Dependent Claim
17 words
A unit according to claim 1 further including means resiliently coupling said pole pieces to said housing.
Claim 5
Dependent Claim
19 words
A unit according to claim 1 further including vibration damping means disposed between said pole pieces and said housing.
Claim 6
Dependent Claim
27 words
A unit according to claim 1 wherein said last-mentioned means is accessible from the outside of said housing for moving said magnet relative to said pole pieces.
Claim 7
Dependent Claim
19 words
A unit according to claim 1 including means for moving said pole pieces toward and away from said housing.
Claim 8
Dependent Claim
202 words
A ski binding assembly for binding a ski to a ski boot, said assembly comprising (1) magnetically conductive means attachable to the toe and heel ends of said ski boot and (2) a pair of binding units attachable to said ski, each of said binding units including: a housing having first and second ends and means for attaching said housing to said ski so that said first and second ends are aligned lengthwise of said ski; means for attaching said housing to said ski; two magnetically conductive pole pieces disposed within and mounted to said housing so that an end surface of each pole piece projects out of said first end of said housing for engagement by said ski boot; a permanent magnet disposed within said housing between and proximate to said pole pieces so as to induce a magnetic field in said pole pieces for magnetically binding said magnetically conductive means to said pole piece end surfaces; said magnet being movable relative to said housing and said pole pieces so as to permit adjustment of the intensity of the magnetic field at said pole piece end surfaces; and means for moving said magnet relative to said housing and said pole pieces.
Claim 9
Dependent Claim
202 words
A ski binding assembly for binding a ski to a ski boot, said assembly comprising (1) magnetically conductive means attachable to the toe and heel ends of said ski boot and (2) a pair of binding units attachable to said ski, each of said binding units including: a housing having first and second ends and means for attaching said housing to said ski so that said first and second ends are aligned lengthwise of said ski; means for attaching said housing to said ski; two magnetically conductive pole pieces disposed within and mounted to said housing so that an end surface of each pole piece projects out of said first end of said housing for engagement by said ski boot; a permanent magnet disposed within said housing between and proximate to said pole pieces so as to induce a magnetic field in said pole pieces for magnetically binding said magnetically conductive means to said pole piece end surfaces; said magnet being movable relative to said housing and said pole pieces so as to permit adjustment of the intensity of the magnetic field at said pole piece end surfaces; and means for moving said magnet relative to said housing and said pole pieces.
