Abstract
Abstract A device for securing a skier's foot to a ski omits the necessity for the typical rigid ski boot and enables the skier to wear non-rigid shoes or boots. The invention relates to a device which is detachably connectible to the bindings of a ski and which includes a foot-receptive framework having interior expandable pads which may be inflated to press firmly against the skier's foot. The pads are inflated by a pump within the device which is operated by the user's foot in response to skiing motion and forces. The extent to which the pads are inflated is controlled by a pressure relief device interposed between the pump and the chocks.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
141 words
A device for securing a skier's foot to a ski, said ski having a binding mounted thereto, the device comprising: a base member detachably connectible to the ski binding; framework means mounted to the base member, the framework means being adapted to receive a skier's foot within the framework; expandable chock means mounted to the interior of the framework to engage and clamp the skier's foot; pump means carried by the framework and in communication with the chock means to supply the chock means with a fluid medium to expand the chock means; said pump means being located within the framework to be operative by motions and forces of the skier's foot on the pump means; and valve means interposed between the pump means and the chock means to control the pressure applied to the chock means by the pump means.
Claim 2
Independent Claim
141 words
A device for securing a skier's foot to a ski, said ski having a binding mounted thereto, the device comprising: a base member detachably connectible to the ski binding; framework means mounted to the base member, the framework means being adapted to receive a skier's foot within the framework; expandable chock means mounted to the interior of the framework to engage and clamp the skier's foot; pump means carried by the framework and in communication with the chock means to supply the chock means with a fluid medium to expand the chock means; said pump means being located within the framework to be operative by motions and forces of the skier's foot on the pump means; and valve means interposed between the pump means and the chock means to control the pressure applied to the chock means by the pump means.
Claim 3
Dependent Claim
13 words
A device as defined in claim 1 wherein the fluid medium is gaseous.
Claim 4
Dependent Claim
43 words
A device as defined in claim 1 wherein the pump means is located within the framework at the heel region thereof so as to be disposed below the skier's heel and to be responsive to vertical movements and forces of the skier's heel.
Claim 5
Dependent Claim
85 words
A device as defined in claim 1 wherein the framework means comprises a pair of shells secured to the base and including a front shell and a rear shell, the front shell being pivoted at its toe region to the base and the rear shell being pivoted at its heel region to the base, the shells being pivotable between a closed, foot-encompassing configuration and an open, foot-receptive configuration; said chock means including at least one chock mounted to the interior of each of the shells.
Claim 6
Dependent Claim
13 words
A device defined in claim 1 wherein the fluid medium comprises a liquid.
Claim 7
Dependent Claim
