Abstract
Abstract A safety binding for a ski has a vertical post 4 over which a plate 5 having front and rear boot engaging ridges 32, 33 is rotatably mounted. The post has a rear transverse groove 15 which accomodates a spring piston biased half-axle 16. A retention lever 18 is secured to the half-axle and extends forward over the post to engage and urge downwardly a transverse pin 23 mounted in a recess 29 in the bottom of a boot. The binding is operated by a pivoted cam lever 38 which withdraws the piston 10 and allows spring 26 in the center of the post to push the lever 18 upwards about the half-axle. Quick release in case of accident is facilitated by the rocking of the boot about the toe or heel whereby pin 23 is forced up and out from under the lever 18.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
227 words
A safety binding assembly for releasably securing a boot to a ski, comprising: a. a base plate (1) integral with a ski, b. a vertical axle post (4) upstanding from the base plate and having a transverse groove (15), c. a rotating plate (5) pivoted about the axle and having front and rear catches (32, 33)thereon, d. a boot (6) having two transverse grooves (30, 31) in its sole (28) adapted to engage the front and rear catches, and a transverse pin (23) mounted in a recess (29) in the sole, e. a transverse axle (16) partially lodged in the transverse groove of the vertical axle and having a surface (20), f. a lever (18) integral with the transverse axle for engaging the transverse pin and urging it toward the rotating plate, g. a housing (9) integral with the rotating plate, h. a sliding piston (10) mounted in the housing and having a front surface (21) bearing against the surface of the transverse axle and forming an acute angel ( Alpha ) therewith, and i. a spring (12) mounted in the housing for urging the piston against the transverse axle and the lever against the transverse pin, the transverse pin and the lever being capable of manual disengagement from each other to detach the boot from the ski, and automatic disengagement in the event of an accident.
Claim 2
Dependent Claim
227 words
A safety binding assembly for releasably securing a boot to a ski, comprising: a. a base plate (1) integral with a ski, b. a vertical axle post (4) upstanding from the base plate and having a transverse groove (15), c. a rotating plate (5) pivoted about the axle and having front and rear catches (32, 33)thereon, d. a boot (6) having two transverse grooves (30, 31) in its sole (28) adapted to engage the front and rear catches, and a transverse pin (23) mounted in a recess (29) in the sole, e. a transverse axle (16) partially lodged in the transverse groove of the vertical axle and having a surface (20), f. a lever (18) integral with the transverse axle for engaging the transverse pin and urging it toward the rotating plate, g. a housing (9) integral with the rotating plate, h. a sliding piston (10) mounted in the housing and having a front surface (21) bearing against the surface of the transverse axle and forming an acute angel ( Alpha ) therewith, and i. a spring (12) mounted in the housing for urging the piston against the transverse axle and the lever against the transverse pin, the transverse pin and the lever being capable of manual disengagement from each other to detach the boot from the ski, and automatic disengagement in the event of an accident.
Claim 3
Dependent Claim
59 words
A safety binding assembly according to claim 1, characterized in that the state of compression of said spring (12) depends on the position of a cam lever (38) for the attachment and detachment of the boot forming a cam (37) having two positions, the one for the attachment of a boot and the other for removal of a boot.
Claim 4
Dependent Claim
34 words
A safety binding assembly according to claim 2, characterized in that the cam (37) acts on a regulating nut (36) disposed on a screw (35) against which abuts an end of said spring (12).
Claim 5
Dependent Claim
62 words
A safety binding assembly according to claim 2, characterized in that the vertical axle (4) is provided with a central hole (24) in which are disposed a piston (25) and a spring (26) pushing said piston against said lever (18) to move it away from the transverse pin (23) when the cam lever (38) is in position for removal of the boot.
Claim 6
Dependent Claim
43 words
A safety binding assembly according to claim 1, characterized in that, in the event of a forward or backward fall, the sole pivots about the front catch or the rear catch (32 and 33 respectively), the transverse pin (23) raising the lever (18).
Claim 7
Dependent Claim
68 words
A safety binding assembly according to claim 1, characterized in that, in the case of a torsional movement between the boot and the ski, the transverse axle (16) partially leaves the transverse groove (15) of the verticle axle (4), pivoting at an intersection (42) of this groove (15) with a peripheral groove (14) of the verticle axle (4) and consequently displacing the lever (18) is a rearward direction.
Claim 8
Dependent Claim
27 words
A safety binding assembly according to claim 1 characterized in that a sliding zone (7) is disposed between the base plate (1) and the rotating plate (5).
