Abstract
Abstract A rear safety boot binding for skis with two-stage recocking requiring much less effort for recocking the binding. The boot heel retaining jaw has a slot accommodating a shaft and a spring abutting against the shaft and the end of the slot. The jaw forms a cam profile in its portion opposed to the boot heel receiving portion with a notch for receiving a stud or the like carried by a lever pivoted on the binding base, a spring constantly urging the stud in contact with the cam profile and being the spring of the safety locking mechanism. When the stud engages the notch, the jaw pivots upwardly about said stud as a first center of rotation and causes compression of the first-named spring, thereby allowing raising of the boot heel up to a certain limit, this constituting the elastic play of the jaw. Upon additional raising of the boot heel, the first-named spring is completely compressed and the jaw pivots about the shaft, causing the safety locking mechanism to release the jaw, thereby resulting in the safety opening of the binding. During this release, the spring of the safety locking mechanism is compressed, thereby constituting the first recocking stage of the binding, while the second recocking stage occurs during downward closing movement of the jaw when a sector-shaped member causes upward movement of the jaw with consequent compression of the first-named spring.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
384 words
A rear safety boot binding for skis comprising a base adapted to be secured to a ski, a boot heel engaging jaw rotatably mounted on said base for vertical movement between closed boot heel clamping position and open boot heel releasing position, said jaw having a boot engaging front portion and a first cam profile with a notch at its back portion, a lever pivoted on said base, a lever spring urging said lever towards said jaw back portion, a stud carried by said lever and engageable with said notch, said lever having a portion accessible exteriorly of said binding, whereby pressure exerted on said portion in one direction will cause compression of the lever spring and release of said stud from engagement with said notch, said cam profile, when said jaw is rotated with said notch out of register with said plunger, engaging said stud and maintaining said lever spring in compressed condition, said jaw having an elongated slot nearly vertical and located intermediate its front portion and its cam profile back portion, a horizontal shaft carried by said base extending through said slot, a second spring disposed within said slot underneath said shaft and abutting said shaft and the lower end of said slot to urge said jaw downwardly relative to said base, a spring-urged pawl carried by said base underneath said jaw, said jaw having a bottom lower portion forming a step and second cam profile extending from said step towards said notch, said cam profile progressively approaching said slot in a direction towards said notch, said pawl engaging said step in the closed position of said jaw, thereby releasing said second spring, upward movement of the front portion of said jaw causing rotation of the latter about a center of rotation defined by the stud engaging said notch and thereby causing compression of said second spring, and further upward movement of said jaw front portion causing maximum compression of said second spring, release of said pawl from engagement with said step, rotation of said jaw about said shaft, release of said stud from said notch and riding of said stud on said first cam profile to maintain the lever spring in compressed condition, and riding of said pawl on said second cam profile to allow decompression of said second spring.
Claim 2
Dependent Claim
384 words
A rear safety boot binding for skis comprising a base adapted to be secured to a ski, a boot heel engaging jaw rotatably mounted on said base for vertical movement between closed boot heel clamping position and open boot heel releasing position, said jaw having a boot engaging front portion and a first cam profile with a notch at its back portion, a lever pivoted on said base, a lever spring urging said lever towards said jaw back portion, a stud carried by said lever and engageable with said notch, said lever having a portion accessible exteriorly of said binding, whereby pressure exerted on said portion in one direction will cause compression of the lever spring and release of said stud from engagement with said notch, said cam profile, when said jaw is rotated with said notch out of register with said plunger, engaging said stud and maintaining said lever spring in compressed condition, said jaw having an elongated slot nearly vertical and located intermediate its front portion and its cam profile back portion, a horizontal shaft carried by said base extending through said slot, a second spring disposed within said slot underneath said shaft and abutting said shaft and the lower end of said slot to urge said jaw downwardly relative to said base, a spring-urged pawl carried by said base underneath said jaw, said jaw having a bottom lower portion forming a step and second cam profile extending from said step towards said notch, said cam profile progressively approaching said slot in a direction towards said notch, said pawl engaging said step in the closed position of said jaw, thereby releasing said second spring, upward movement of the front portion of said jaw causing rotation of the latter about a center of rotation defined by the stud engaging said notch and thereby causing compression of said second spring, and further upward movement of said jaw front portion causing maximum compression of said second spring, release of said pawl from engagement with said step, rotation of said jaw about said shaft, release of said stud from said notch and riding of said stud on said first cam profile to maintain the lever spring in compressed condition, and riding of said pawl on said second cam profile to allow decompression of said second spring.
Claim 3
Dependent Claim
21 words
A rear safety binding as claimed in claim 1, further including means to adjust the pressure exerted by said lever spring.
Claim 4
Dependent Claim
185 words
A safety boot binding for skis comprising a base structure adapted to be secured to a ski, a jaw articulated relative to said base structure and having a front portion adapted to cooperate with a booth sole, said jaw capable of vertical displacement between closed and open positions, a jaw safety locking member mounted on said base structure at the back of said jaw and spring urged towards said jaw, said jaw having a locking profile facing rearwardly of said jaw and cooperating with said locking member, whereby said locking member can lock said jaw in closed position, an elastic member acting between a part which is fixed to said base structure and said jaw, and urging said jaw towards said base structure in an elastic vertical limited movement of said jaw, a jaw guiding member mounted on said base structure below said jaw, said jaw having a bottom portion defining a cam profile cooperating with said jaw guiding member to cause guiding of said jaw, with compression and then release of said elastic member during safety release of the jaw and during boot clamping.
