Claim 1
Independent Claim
243 words
A ski safety binding for connection to a ski board which comprises heel holding means for holding the heel of a ski boot; said heel holding means including base plate means for connection to a ski board, magnetic holding means supported by said base plate means, soft iron plate means associated with said magnetic holding means and adapted to be magnetically secured thereby though capable of being opened from all directions while tilting moments are hindered from being effective on said magnetic holding means, heel grasping means for grasping the heel of a ski boot, and connecting means connecting said heel grasping means at one end thereof to said soft iron plate means, said heel grasping means comprising tongue means rigidly connected to the other end thereof for supporting a ski boot from below and also comprising a mechanical clamping member connected to said other end and positioned above said tongue means for tightly grasping a ski boot heel therebetween, and means provided in the forward portion of said base plate for restricting a lateral movement of said tongue means to permit only vertical lifting off of said magnetic holding means so that tilting moments cannot arise and so that always the entire holding force of said magnetic holding means must be overcome before the binding opens and that further opening of the binding occurs as a result of each loading that is too strong independently thereof from which direction the loading arises.
Claim 2
Dependent Claim
243 words
A ski safety binding for connection to a ski board which comprises heel holding means for holding the heel of a ski boot; said heel holding means including base plate means for connection to a ski board, magnetic holding means supported by said base plate means, soft iron plate means associated with said magnetic holding means and adapted to be magnetically secured thereby though capable of being opened from all directions while tilting moments are hindered from being effective on said magnetic holding means, heel grasping means for grasping the heel of a ski boot, and connecting means connecting said heel grasping means at one end thereof to said soft iron plate means, said heel grasping means comprising tongue means rigidly connected to the other end thereof for supporting a ski boot from below and also comprising a mechanical clamping member connected to said other end and positioned above said tongue means for tightly grasping a ski boot heel therebetween, and means provided in the forward portion of said base plate for restricting a lateral movement of said tongue means to permit only vertical lifting off of said magnetic holding means so that tilting moments cannot arise and so that always the entire holding force of said magnetic holding means must be overcome before the binding opens and that further opening of the binding occurs as a result of each loading that is too strong independently thereof from which direction the loading arises.
Claim 3
Dependent Claim
68 words
A ski safety binding according to claim 1, in which said base plate means is provided with a longitudinal recess having said tongue means held therein, width of said tongue means corresponding to width of the recess having at least some side offset therebetween so that upon encountering too strong lateral loading there occurs pressing out and simultaneous vertical lifting of said tongue means out of the recess.
Claim 4
Dependent Claim
61 words
A ski safety binding according to claim 2, in which said tongue means and said clamping member together form a clamp of U-shaped cross-section in the plane of symmetry of said base plate means perpendicularly to the top and bottom surfaces thereof, and bolt means substantially coaxial with said magnetic means and connecting said clamp to said soft iron plate means.
Claim 5
Dependent Claim
21 words
A ski safety binding according to claim 3, which includes elastic washer means interposed between said clamp and said bolt means.
Claim 6
Dependent Claim
24 words
A ski safety binding according to claim 3, in which said clamp is provided with a longitudinal hole for introducing said bolt means therethrough.
Claim 7
Dependent Claim
73 words
A ski safety binding according to claim 1, in which said base plate means for connection to a ski board is provided with longitudinal bores extending in the longitudinal direction of said base plate means and provided with transverse groove means, and which includes toothed washer means having the teeth thereof in engagement with said groove means, and screw means extending through said washer means for connecting the same to a ski board.
Claim 8
Dependent Claim
197 words
A ski safety binding for connection to a ski board which comprises heel holding means for holding the heel of a ski boot, said heel holding means including base plate means for connection to a ski board, magnetic means supported by said base plate means, soft iron plate means associated with said magnetic means and adapted to be magnetically held thereby, heel grasping means for grasping the heel of a ski boot, and connecting means connecting said heel grasping means to said soft iron plate means, said heel grasping means comprising tongue means for supporting a ski boot from below and also comprising a clamping member for grasping a ski boot heel from behind and holding the same in position, hollow bolt means forming said connecting means and extending through said soft iron plate means, the outer end of said bolt means having an inner thread, detachable screw means in threaded adjustable engagement with said inner thread, slidable pin means arranged within said hollow bolt means and having one end in engagement with said magnetic means, and spring means interposed between said screw means and said pin means and continuously urging the latter toward said magnetic means.
Claim 9
Dependent Claim
197 words
