Abstract
Abstract A ski binding comprising an interengaging mechanism between the ski boot and the ski, allowing the skier to transfer his weight to the ski. The essential elements of the binding consist of a plug member and an interengaging socket member, one of the members being associated with the ski boot and the other with the ski. In a preferred form, the plug member is removably secured to the ski and the socket member is associated with the boot; it may be integrally formed with the sole or removably inserted in a recess formed therein. The ski binding has a central rotational member journaled in the plug member for selectively loading and at least partly unloading detent elements by means of interposed parts, such as pawls and supports therefor. The detent elements are either balls or plunger-like elements, by which the two members are allowed to become detached from one another. The socket member has an opening sufficient to receive the plug member. The latter may be made with flat outer sides so as to allow additional clearance between the interengaging members. A plurality of recesses are spaced on the inner wall of the socket member to register with the detent elements of the plug member. Any force whether longitudinal of the ski, or as a torque about the skier''s body or legs, will develop a reactive force through or about the area of the geometric center of the binding. If the force is sufficient in magnitude and duration an automatic separation of the interengaging members is effected in response to the force. The invention also provides an over-center action lever arrangement by which the loading force on the detent elements can be selectively applied and at least partly removed when the skier attaches or removes the ski.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
265 words
A ski binding for removably attaching a skier''s boot to a ski, comprising: an interengaging mechanism between the boot and the ski, said mechanism having engaging portions forward of the heel portion of the boot and rearward of the toe portion thereof, operatively secured to coextensive but opposing portions of said interengaging mechanism; said engaging portions being constituted by a plug member and a socket member, the former removably secured to the ski and the latter associated with the boot; detent means forming part of said plug and socket members for positive indexing therebetween in their respective planes as well as in angular directions with respect to the longitudinal axes of the boot and the ski; said plug member having at least three outwardly directed passages; said detent means including the same number of captive detent elements protruding from said passages, and the same number of recesses on the inner periphery of said socket member; said engaging portions reacting by relative rotational movement, movement out of said planes of the engaging portions, and a combination of said movements, upon occurrence of a force of predetermined magnitude and duration, thereby allowing release of said engaging portions from each other and of the boot from the ski when the skier encounters a major obstacle which results in said force; a central rotational zig-zag) in said plug member with freedom of at elements partial angular movement; associated with said detent elements for symmEtrically and simultaneously applying loading force thereto; and non-radially disposed pawl members in at least one plane, interposed between said rotational member and said detent elements.
Claim 2
Dependent Claim
265 words
A ski binding for removably attaching a skier''s boot to a ski, comprising: an interengaging mechanism between the boot and the ski, said mechanism having engaging portions forward of the heel portion of the boot and rearward of the toe portion thereof, operatively secured to coextensive but opposing portions of said interengaging mechanism; said engaging portions being constituted by a plug member and a socket member, the former removably secured to the ski and the latter associated with the boot; detent means forming part of said plug and socket members for positive indexing therebetween in their respective planes as well as in angular directions with respect to the longitudinal axes of the boot and the ski; said plug member having at least three outwardly directed passages; said detent means including the same number of captive detent elements protruding from said passages, and the same number of recesses on the inner periphery of said socket member; said engaging portions reacting by relative rotational movement, movement out of said planes of the engaging portions, and a combination of said movements, upon occurrence of a force of predetermined magnitude and duration, thereby allowing release of said engaging portions from each other and of the boot from the ski when the skier encounters a major obstacle which results in said force; a central rotational zig-zag) in said plug member with freedom of at elements partial angular movement; associated with said detent elements for symmEtrically and simultaneously applying loading force thereto; and non-radially disposed pawl members in at least one plane, interposed between said rotational member and said detent elements.
Claim 3
Dependent Claim
