Abstract
Abstract The safety release ski boot system comprises a ski boot having a boot upper body, a fixed upper sole attached to the upper body, a detachable lower sole releasably secured to the upper sole, and a safety release mechanism contained within the detachable lower sole which releasably secures the lower sole to the fixed upper sole of the ski boot. The safety release mechanism comprises at least two rotatable latch members one of which is pivotally mounted at the forward end and another of which is pivotally mounted at the rearward end of the lower sole. Each latch member is rotatable about its pivot axis from a lowermost ski boot release position to an uppermost ski boot engaging position and return. Separately adjustable spring means engage each rotatable latch member at a pivot point eccentric with respect to the pivot axis of the latch member. Each rotatable latch member is urged by the adjustable spring means associated therewith to its ski boot engaging position when the eccentric pivot point is positioned below the pivot axis of the latch member and is urged to its ski boot release position when the eccentric pivot point is positioned above the pivot axis of the latch member.

Total Claims: 19
Claim 1
Independent Claim
241 words
Safety release ski boot system comprising a ski boot assembly having a boot upper body, a fixed upper sole attached to the upper body, a detachable lower sole normally secured to the upper sole and a safety release mechanism contained within the detachable lower sole of the ski boot assembly, said detachable lower sole being releasably secured to the fixed upper sole of the ski boot assembly by said safety release mechanism, said safety release mechanism comprising: at least two rotatable latch members one of which is pivotally mounted on the lower sole at the forward end thereof and another of which is pivotally mounted on the lower sole at the rearward end thereof, each of said latch members being rotatable about its pivot axis from a lowermost ski boot release position to an uppermost ski boot engaging position and return, and separately adjustable spring means engaging each rotatable latch member at a pivot point eccentric with respect to the pivot axis of said latch member, each adjustable spring means urging the latch member with which it is associated to its uppermost ski boot engaging position when the latch member is rotated so that the eccentric pivot point is positioned below the pivot axis and said spring means urging said latch member to its lowermost ski boot release position when said latch means is rotated so that the eccentric pivot point is positioned above the pivot axis of the latch member.
Claim 2
Dependent Claim
241 words
Safety release ski boot system comprising a ski boot assembly having a boot upper body, a fixed upper sole attached to the upper body, a detachable lower sole normally secured to the upper sole and a safety release mechanism contained within the detachable lower sole of the ski boot assembly, said detachable lower sole being releasably secured to the fixed upper sole of the ski boot assembly by said safety release mechanism, said safety release mechanism comprising: at least two rotatable latch members one of which is pivotally mounted on the lower sole at the forward end thereof and another of which is pivotally mounted on the lower sole at the rearward end thereof, each of said latch members being rotatable about its pivot axis from a lowermost ski boot release position to an uppermost ski boot engaging position and return, and separately adjustable spring means engaging each rotatable latch member at a pivot point eccentric with respect to the pivot axis of said latch member, each adjustable spring means urging the latch member with which it is associated to its uppermost ski boot engaging position when the latch member is rotated so that the eccentric pivot point is positioned below the pivot axis and said spring means urging said latch member to its lowermost ski boot release position when said latch means is rotated so that the eccentric pivot point is positioned above the pivot axis of the latch member.
