Abstract
Abstract A ski boot with adjustable flex control includes a substantially rigid cuff portion and a substantially rigid boot portion pivotally coupled to a lower portion of the cuff portion. A groove defined between the cuff and boot portions receives a movable cursor whose movement along the length of the groove varies the flexure characteristics of the boot. The cursor is wholly located within the groove for shielding by the cuff and boot portions from engaging a ski. A detent mechanism within the cursor engages recesses in the groove to lock the cursor selectively in a series of discrete, predetermined positions. The detent mechanism comprises a spring biased bolt member mounted in a bore and movable axially within the cursor such that the bolt mechanism and its movement are wholly located within the groove. The locking and unlocking operations are accomplished by axial movement of the bolt member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
170 words
A ski boot, comprising: a substantially rigid cuff portion having a first curved outer surface and a first support member; a substantially rigid boot portion pivotally coupled to a lower portion of said cuff portion, said boot portion having a second curved outer surface and a second support member, said support members being generally parallel and defining an elongated groove therebetween, said groove having a base surface between said support members, a groove longitudinal axis, and an outer periphery defined by said outer surfaces; and a cursor mounted in said groove for movement along a length thereof, said cursor having an inner surface in contact with said base surface and an outermost surface, opposite said inner surface, wholly within said outer periphery of said groove, such that no portion of said cursor extends outside of said groove; whereby, flexure characteristics of the ski boot can be varied by moving said cursor to various positions in said groove, and said cursor is shielded by said cuff portion and said boot portion.
Claim 2
Dependent Claim
170 words
A ski boot, comprising: a substantially rigid cuff portion having a first curved outer surface and a first support member; a substantially rigid boot portion pivotally coupled to a lower portion of said cuff portion, said boot portion having a second curved outer surface and a second support member, said support members being generally parallel and defining an elongated groove therebetween, said groove having a base surface between said support members, a groove longitudinal axis, and an outer periphery defined by said outer surfaces; and a cursor mounted in said groove for movement along a length thereof, said cursor having an inner surface in contact with said base surface and an outermost surface, opposite said inner surface, wholly within said outer periphery of said groove, such that no portion of said cursor extends outside of said groove; whereby, flexure characteristics of the ski boot can be varied by moving said cursor to various positions in said groove, and said cursor is shielded by said cuff portion and said boot portion.
Claim 3
Dependent Claim
42 words
A ski boot according to claim 1 wherein one of said support members comprises a plurality of recesses opening into said groove; and said cursor comprises a detent means, movable into and out of said recesses, for locking said cursor in position.
Claim 4
Dependent Claim
56 words
A ski boot according to claim 2 wherein said detent means comprises an elongated bolt member having a longitudinal bolt axis extending substantially parallel to said groove axis and axially slidable in said cursor, and a latch member mounted for movement into and out of said recesses in response to axial movement of said bolt member.
Claim 5
Dependent Claim
28 words
A ski boot according to claim 3 wherein said bolt member is biased by a spring towards a position forcing said latch member into one of said recesses.
Claim 6
Dependent Claim
84 words
A ski boot according to claim 4 wherein said bolt member comprises a depression and a projection selectively locatable adjacent said latch member upon axial movement of said bolt member, said latch member being receivable in said depression to allow withdrawal of said latch member from one of said recesses and into said cursor, said projection being engagable with said latch member preventing withdrawal of said latch member from one of said recesses and locking said cursor in a desired position in said groove.
Claim 7
Dependent Claim
34 words
A ski boot according to claim 5 wherein said bolt member is received in a bore in said cursor, said bore having means preventing rotation of said bolt member about said longitudinal axis thereof.
Claim 8
Dependent Claim
29 words
A ski boot according to claim 1 wherein said cursor and one of said cuff portion and said boot portion are slidably engaged by a tongue and groove arrangement.
Claim 9
Dependent Claim
30 words
A ski boot according to claim 1 wherein said groove has an enlarged width at a lowermost portion thereof where said cursor is spaced from one of said support members.
Claim 10
Dependent Claim
158 words
A ski boot, comprising: a substantially rigid cuff portion having a first support member; a substantially rigid boot portion pivotally coupled to a lower portion of said cuff portion, said boot portion having a second support member, said support members being generally parallel and defining an elongated groove therebetween with a groove longitudinal axis; a cursor mounted in said groove for movement along a length thereof, one of said support members having a plurality of recesses opening into said groove; and detent means for locking said cursor in position, said detent means having an elongated bolt member with a longitudinal bolt axis extending substantially parallel to said groove axis and axially slidable in said cursor, and having a latch member mounted for movement into and out of said recesses in response to axial movement of said bolt member; whereby, flexure characteristics of the ski boot can be varied by moving said cursor to various positions in said groove.
Claim 11
Dependent Claim
158 words
A ski boot, comprising: a substantially rigid cuff portion having a first support member; a substantially rigid boot portion pivotally coupled to a lower portion of said cuff portion, said boot portion having a second support member, said support members being generally parallel and defining an elongated groove therebetween with a groove longitudinal axis; a cursor mounted in said groove for movement along a length thereof, one of said support members having a plurality of recesses opening into said groove; and detent means for locking said cursor in position, said detent means having an elongated bolt member with a longitudinal bolt axis extending substantially parallel to said groove axis and axially slidable in said cursor, and having a latch member mounted for movement into and out of said recesses in response to axial movement of said bolt member; whereby, flexure characteristics of the ski boot can be varied by moving said cursor to various positions in said groove.
