Abstract
Abstract A safety ski binding with a sole plate having structure facilitating a connection of a ski boot thereto. The two ends of the sole plate each engage a ski-fixed holding part and, through the provision of a locking mechanism prevents the sole plate from rotating and lifting off from the ski in the area of the ends of the sole plate. The sole plate is rotably supported approximately in its center about a ski-fixed pin which extends perpendicularly with respect to the upper surface of the ski and the pin is received in a recess in the sole plate and has structure for preventing removal of the sole plate. A sleeve is provided between the exterior surface of the pin and the interior wall of the recess in the sole plate, which sleeve is movable telescopically along the wall of the recess, and the maximum path of movement of the sleeve in the recess is fixed by stops.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
166 words
In a safety ski binding for use on a ski comprising a sole plate having first means thereon for fastening a ski boot thereto and second means operatively releasably coupled to the longitudinal ends of said sole plate for releasably securing said sole plate against rotation and against a lifting off from said ski, a pin means secured to said ski and extending perpendicularly with respect to the upper surface of said ski, and a recess in said sole plate receiving said pin means therein, the improvement comprising wherein said pin means includes a pin secured to said ski and a hollow sleeve movable telescopically along the length of said pin and along the length of said recess and stop means for limiting the maximum path of movement of the sleeve relative to said pin and said recess and to limit the amount of separation between said sole plate and said ski adjacent said recess and said pin when said ski is flexed into an arc.
Claim 2
Dependent Claim

In a safety ski binding for use on a ski comprising a sole plate having first means thereon for fastening a ski boot thereto and second means operatively releasably coupled to the longitudinal ends of said sole plate for releasably securing said sole plate against rotation and against a lifting off from said ski, a pin means secured to said ski and extending perpendicularly with respect to the upper surface of said ski, and a recess in said sole plate receiving said pin means therein, the improvement comprising wherein said pin means includes a pin secured to said ski and a hollow sleeve movable telescopically along the length of said pin and along the length of said recess and stop means for limiting the maximum path of movement of the sleeve relative to said pin and said recess and to limit the amount of separation between said sole plate and said ski adjacent said recess and said pin when said ski is flexed into an arc.
Claim 3
Dependent Claim
122 words
The ski binding according to claim 1, wherein said stop means includes an annular flange on the free end of said pin having a diameter which is greater than the diameter of said pin and corresponds substantially with the inner diameter of said hollow sleeve, said stop means further including an inwardly projecting flange on the end of said sleeve adjacent said upper surface of said ski, the inside diameter of which corresponds substantially with the diameter of said pin, said sleeve having at its other end an outwardly projecting rim, the outside diameter of which is equal to or slightly smaller than the diameter of said recess, the inside diameter of which corresponds substantially with the outside diameter of the sleeve
Claim 4
Dependent Claim
51 words
The ski binding according to claim 1 or 2, wherein both said pin with its flange and also said sleeve with the upper surface of its outwardly projecting rim lies in the normal and unflexed condition of said sole plate in one plane with the upper surface of said sole plate.
Claim 5
Dependent Claim
42 words
The ski binding according to claim 1, wherein between said pin and said sleeve, there is arranged a spring which prevents a lifting of said sleeve from the upper surface of said ski in the normal and unflexed condition of said ski.
Claim 6
Dependent Claim
47 words
The ski binding according to claim 1 or 2, wherein said recess in said sole plate is covered on the upper side of said sole plate with a disk which has a hole therein, the central axis of which is concentric with the axis of said pin.
Claim 7
Dependent Claim
23 words
The ski binding according to claim 5, wherein upper surface of said disk is flush with the upper surface of said sole plate.
Claim 8
Dependent Claim
21 words
The ski binding according to claim 5, wherein the diameter of said hole corresponds substantially with the diameter of said flange.
Claim 9
Dependent Claim
32 words
The ski binding according to claim 5, wherein the upper end surface of said pin terminates flush with the upper surface of said disk and the upper surface of said sole plate.
Claim 10
Dependent Claim
48 words
The ski binding according to claim 5, wherein said flange on said pin lies in the normal and unflexed condition of said ski in said hole in said disk, said disk thereby preventing in this position of the ski a rattling movement of said sleeve in said recess.
