Abstract
Abstract A heel clip for releasably attaching a heel of a ski boot to a ski includes a framework pivotally mounted on the ski. A first member is pivotally connected to the framework for movement between first and second positions. In the first position, a second member pivotally connected to the first member engages a stop member and a clamp connected to the second member firmly engages the heel of a ski boot. When the heel exerts a sudden force sufficient to overcome a spring biasing the first member in the first position, the first member moves to the second position whereupon a groove in the second member receives therein the stop member thereby permitting the second member to pivot relative to the first member. This pivotal movement causes the clamp to release the heel of the ski boot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
245 words
A heel clip for releasably attaching a heel of a ski boot to a ski comprising: a framework rotatably mounted on the ski, a first member pivotally connected to the framework for pivotal movement between a first position and a second position, a seconD member having means therein defining a groove and pivotally connected to said first member for movement with said first member, a clamp connected to said second member having means for releasably engaging with the heel of the ski boot for maintaining the ski boot in an operative position on the ski when said first member is in said first position, a stop member engageable with a portion of said second member to prevent pivotal movement of said second member relative to the first member when said first member is in said first position and movable into said groove in said second member thereby permitting sufficient pivotal movement of the second member relative to the first member to release the clamp from the heel when said first member is moved into said second position, and resilient biasing means biasing said first member into said first position with a predetermined biasing force capable of being overcome by an external force applied by the heel of the ski boot having a force component greater in magnitude than said biasing force and acting in a direction opposite to said biasing force whereupon said first member is moved from said first position into said second position.
Claim 2
Dependent Claim
245 words
A heel clip for releasably attaching a heel of a ski boot to a ski comprising: a framework rotatably mounted on the ski, a first member pivotally connected to the framework for pivotal movement between a first position and a second position, a seconD member having means therein defining a groove and pivotally connected to said first member for movement with said first member, a clamp connected to said second member having means for releasably engaging with the heel of the ski boot for maintaining the ski boot in an operative position on the ski when said first member is in said first position, a stop member engageable with a portion of said second member to prevent pivotal movement of said second member relative to the first member when said first member is in said first position and movable into said groove in said second member thereby permitting sufficient pivotal movement of the second member relative to the first member to release the clamp from the heel when said first member is moved into said second position, and resilient biasing means biasing said first member into said first position with a predetermined biasing force capable of being overcome by an external force applied by the heel of the ski boot having a force component greater in magnitude than said biasing force and acting in a direction opposite to said biasing force whereupon said first member is moved from said first position into said second position.
Claim 3
Dependent Claim
26 words
A heel clip according to claim 1, wherein said stop member comprises a shaft mounted on said framework, and a roller rotatably mounted on said shaft.
Claim 4
Dependent Claim
37 words
A heel clip according to claim 1, wherein said resilient biasing means comprises a screw threadably engaged on said framework, a nut adjustably threaded on said screw, and a spring engaging a surface portion of said nut.
Claim 5
Dependent Claim
28 words
A heel clip according to claim 1, including a spring for biasing said second member against said stop member when said first member is in said first position.
Claim 6
Dependent Claim
57 words
A heel clip according to claim 1, including a slide connected to the ski, a pin rigidly connected to the slide and having pivotally mounted thereon said framework, a flange on said pin having means therein defining a groove, and a ball disposed within said groove between said flange and a surface portion of said first member.
Claim 7
Dependent Claim
18 words
A heel clip according to claim 5, wherein said groove comprises a radial groove for engaging the ball.
Claim 8
Dependent Claim
78 words
A heel clip according to claim 1, including a lever pivotally connected to said framework, a projection projecting outwardly from said lever engageable with the pivotal connection between said first and second members in response to pivotal movement of said lever to permit said stop member to enter said groove in said second member thereby permitting pivotal movement of said second member relative to said first member to release said clamp from the heel of the ski boot.
Claim 9
Dependent Claim
14 words
A heel clip according to claim 7, including a strap connected to said lever.
Claim 10
Dependent Claim
67 words
A heel clip according to claim 1 including a sole rigidly connected to the ski, means defining a plurality of equi-spaced grooves in a surface portion of said sole, a worm screw having threads in meshing engagement with said grooves, and means connecting said worm screw to said framework for effecting movement of said framework along said sole in response to rotational movement of said worm screw.
Claim 11
Dependent Claim
29 words
A heel clip according to claim 9, including a manipulating head accessible from outside said framework and connected to said worm screw for effecting rotation of said worm screw.
