Abstract
Abstract Release device for reception into the sole of a ski boot. An engaging unit is provided for location in the sole of a ski boot and same cooperates with upstanding means fixedly related to the upper surface of a ski. When the ski boot is parallel with the longitudinal axis of the ski, the holder operates in a normal manner to resist forces tending to urge the ski boot directly upwardly. However, when the ski boot is partially turned with respect to the center line of the ski, then the latching mechanism is moved partway toward its release position and a less total force is required to effect the safety release. Thus, in a twisting or diagonal fall, when the bone of the skier is subjected to both bending and torsional forces, the release takes place at lesser force and the skier''s safety is thereby enhanced.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
262 words
A releasable ski binding for releasably securing the sole of a ski boot to a ski, comprising: post means fixedly secured to said ski and extending upwardly therefrom and having means defining a pair of locking recesses thereon each facing in opposite longitudinal directions relative to said ski; housing means mounted on the sole of said ski boot; abutment means mounted on said housing means; first locking means mounted on said housing means and adapted to move longitudinally of said ski boot toward and away from said abutment means, an opening being defined between said abutment means and said first locking means when said first locking means is moved away from said abutment means for receiving said post means therein, said first locking means being adapted to engage said post means, while in said opening, in one of said locking recesses; second locking means mounted on said housing means and adapted to releasably engage said post means in the other of said locking recesses when said first locking means is engaged with said post means and effecting a coupling of said housing means to said post means when the longitudinal axis of said sole of said ski boot is parallel to the longitudinal axis of said ski; and means for effecting a separation of said second locking means from said post means to thereby effect a decrease in the coupling force holding said ski boot on said ski whenever said longitudinal axis of said sole of said ski boot is twisted out of parallel relationship with the longitudinal axis of said ski.
Claim 2
Dependent Claim
262 words
A releasable ski binding for releasably securing the sole of a ski boot to a ski, comprising: post means fixedly secured to said ski and extending upwardly therefrom and having means defining a pair of locking recesses thereon each facing in opposite longitudinal directions relative to said ski; housing means mounted on the sole of said ski boot; abutment means mounted on said housing means; first locking means mounted on said housing means and adapted to move longitudinally of said ski boot toward and away from said abutment means, an opening being defined between said abutment means and said first locking means when said first locking means is moved away from said abutment means for receiving said post means therein, said first locking means being adapted to engage said post means, while in said opening, in one of said locking recesses; second locking means mounted on said housing means and adapted to releasably engage said post means in the other of said locking recesses when said first locking means is engaged with said post means and effecting a coupling of said housing means to said post means when the longitudinal axis of said sole of said ski boot is parallel to the longitudinal axis of said ski; and means for effecting a separation of said second locking means from said post means to thereby effect a decrease in the coupling force holding said ski boot on said ski whenever said longitudinal axis of said sole of said ski boot is twisted out of parallel relationship with the longitudinal axis of said ski.
Claim 3
Dependent Claim
77 words
A releasable ski binding according to claim 1, wherein said second locking means comprises a cylindrical rod rotatably mounted on said housing means about a substantially horizontal axis and positioned adjacent said abutment means; and wherein said other of said locking recesses comprises a semicircular recess opening outwardly of said post means, the axis of which extends perpendicular to the vertical axis of said post means and is of a diameter adapted to receive said rod therein.
Claim 4
Dependent Claim
45 words
A releasable ski binding according to claim 2, wherein said abutment means includes means defining a recess therein opening outwardly of said abutment means in a direction facing said post means and aligned with said semicircular recess, said recess having said rod rotatably mounted therein.
Claim 5
Dependent Claim
97 words
A releasable ski binding according to claim 3, wherein said rod has means defining a flat part on one side thereof, said flat part, when in a first position facing said post means, permitting an obstacle free relative vertical movement between said post means and said housing means and when said flat part is rotated to a second position 180* from said first position, the cylindrical part of said rod being received in said other of said locking recesses to define an obstacle to resist any relative vertical movement between said post means and said housing means.
Claim 6
Dependent Claim
49 words
A releasable ski binding according to claim 1, wherein said first locking means comprises a locking element, means supporting said locking element for sliding movement on said housing means in the longitudinal direction of said ski boot and resilient means for urging said locking element toward said abutment means.
Claim 7
Dependent Claim
46 words
A releasable ski binding according to claim 5, wherein said one of said locking recesses comprises a first vertically extending channel having a pair of horizontally spaced sidewalls; and wherein said locking element is urged into said first channel between said sidewalls by said resilient means.
Claim 8
Dependent Claim
45 words
A releasable ski binding according to claim 6, wherein said other of said locking recesses comprises a second vertically extending channel having a pair of horizontally spaced sidewalls; and wherein said abutment means is adapted to be received in said second channel between said sidewalls.
Claim 9
Dependent Claim
96 words
A releasable ski binding according to claim 5, wherein said first locking means further comprises a slide member separate from said locking element and adapted to slide on said housing means in said longitudinal direction and stop means for limiting the longitudinal sliding movement of said slide member toward said abutment means; and wherein said resilient means comprises a first spring positioned between said housing means and said slide member to urge said slide member toward said stop means and said abutment means and a second spring positioned between said slide member and said locking element.
Claim 10
Dependent Claim
18 words
A releasable ski binding according to claim 8, wherein said second spring is weaker than said first spring.
Claim 11
Dependent Claim
55 words
A releasable ski binding according to claim 1, including a pair of supports slidably secured to said ski on opposite longitudinal sides of said post means and slidable in the longitudinal direction of said ski and clamp means for fixedly clamping said supports into a desired position on said ski relative to said post means.
Claim 12
Dependent Claim
58 words
A releasable ski binding according to claim 10, wherein each of said supports includes a surface spaced upwardly from the upper surface of said ski; and wherein said supports are positioned inwardly from the toe and heel of said sole of said ski boot to support said ski boot in a vertically spaced relation from said ski boot.
Claim 13
Dependent Claim
44 words
A releasable ski binding according to claim 11, wheRein the longitudinal spacing between said supports and said post means defines a leverage arrangement and thereby the moment required to effect a release of the engagement between said post means and said second locking means.
