Abstract
Abstract A ski binding to releasably hold a ski boot has a mechanism for holding the toe of the skier''s boot which releases the boot when the lateral or upward forces of the boot toe in the binding reach predetermined levels. The ratio between the lateral and vertical forces necessary for release of the boot toe is fixed by the toe release mechanism and may be varied by substituting interchangable parts in the mechanism.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
231 words
A ski binding having a toe release mechanism comprising: a toe post member having: a first portion adapted to engage a toe plate of a ski boot; and a second portion adapted to engage resilient means; resilient means contacting said second portion of said toe post member to urge said first portion of said toe post member toward engagement with said toe plate; fulcruming means connected to said toe post member and having two side surfaces, said fulcruming means coacting with said resilient means to urge said first portion of said toe post member into position for operative engagement with said toe plate; a housing adapted to be secured to a ski and enclosing at least a portion of said toe post member and said resilient means, said housing having; a front wall providing a fulcruming surface for said fulcruming means; a rear wall engaged by said resilient means; and two side walls disposed on opposite sides of said front wall and continuous with said rear wall; said fulcruming means dimensioned to provide a ratio of fulcrum effect against vertical and lateral displacement of said first portion of said toe post member; and said housing dimensioned so that the said side walls of the housing coact with the said surfaces of the fulcruming means to prevent rotation of the fulcruming means with relation to the said front wall of the housing.
Claim 2
Dependent Claim
231 words
A ski binding having a toe release mechanism comprising: a toe post member having: a first portion adapted to engage a toe plate of a ski boot; and a second portion adapted to engage resilient means; resilient means contacting said second portion of said toe post member to urge said first portion of said toe post member toward engagement with said toe plate; fulcruming means connected to said toe post member and having two side surfaces, said fulcruming means coacting with said resilient means to urge said first portion of said toe post member into position for operative engagement with said toe plate; a housing adapted to be secured to a ski and enclosing at least a portion of said toe post member and said resilient means, said housing having; a front wall providing a fulcruming surface for said fulcruming means; a rear wall engaged by said resilient means; and two side walls disposed on opposite sides of said front wall and continuous with said rear wall; said fulcruming means dimensioned to provide a ratio of fulcrum effect against vertical and lateral displacement of said first portion of said toe post member; and said housing dimensioned so that the said side walls of the housing coact with the said surfaces of the fulcruming means to prevent rotation of the fulcruming means with relation to the said front wall of the housing.
Claim 3
Dependent Claim
231 words
A ski binding having a toe release mechanism comprising: a toe post member having: a first portion adapted to engage a toe plate of a ski boot; and a second portion adapted to engage resilient means; resilient means contacting said second portion of said toe post member to urge said first portion of said toe post member toward engagement with said toe plate; fulcruming means connected to said toe post member and having two side surfaces, said fulcruming means coacting with said resilient means to urge said first portion of said toe post member into position for operative engagement with said toe plate; a housing adapted to be secured to a ski and enclosing at least a portion of said toe post member and said resilient means, said housing having; a front wall providing a fulcruming surface for said fulcruming means; a rear wall engaged by said resilient means; and two side walls disposed on opposite sides of said front wall and continuous with said rear wall; said fulcruming means dimensioned to provide a ratio of fulcrum effect against vertical and lateral displacement of said first portion of said toe post member; and said housing dimensioned so that the said side walls of the housing coact with the said surfaces of the fulcruming means to prevent rotation of the fulcruming means with relation to the said front wall of the housing.
Claim 4
Dependent Claim
231 words
A ski binding having a toe release mechanism comprising: a toe post member having: a first portion adapted to engage a toe plate of a ski boot; and a second portion adapted to engage resilient means; resilient means contacting said second portion of said toe post member to urge said first portion of said toe post member toward engagement with said toe plate; fulcruming means connected to said toe post member and having two side surfaces, said fulcruming means coacting with said resilient means to urge said first portion of said toe post member into position for operative engagement with said toe plate; a housing adapted to be secured to a ski and enclosing at least a portion of said toe post member and said resilient means, said housing having; a front wall providing a fulcruming surface for said fulcruming means; a rear wall engaged by said resilient means; and two side walls disposed on opposite sides of said front wall and continuous with said rear wall; said fulcruming means dimensioned to provide a ratio of fulcrum effect against vertical and lateral displacement of said first portion of said toe post member; and said housing dimensioned so that the said side walls of the housing coact with the said surfaces of the fulcruming means to prevent rotation of the fulcruming means with relation to the said front wall of the housing.
Claim 5
Dependent Claim
52 words
The ski binding according to claim 1, wherein said resilient means comprise: a thrust member contacting said second portion of said toe post member; and spring means contacting said thrust member and said rear wall of the housing to urge said thrust member against said second portion of said toe post member.
Claim 6
Dependent Claim
31 words
The ski binding according to claim 2, wherein: said second portion of said toe post includes pin means; and the thrust member has socket means adapted to receive said pin means.
