Abstract
Abstract In a mounting device for the heel of a ski boot, a sole depressor is lockable in a heel-engaging pivoted position irrespective of the sole thickness or any snow packed beneath the sole. A locking arm carried by the sole depressor or a frame member passes through a hole in a clamping plate pivoted to the frame member or depressor, respectively. A spring acts on the clamping plate so that the locking arm is canted in the hole and binds on the edges of the hole, thereby locking the sole depressor against movement to a heel-releasing position. A handle can deliberately unlock the sole depressor by straightening the clamping plate against the action of the spring so that the locking arm is no longer canted and no longer binds on the edges of the hole.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
216 words
A mounting device for the heel of a ski boot in a ski binding for a ski, comprising a frame member securable to the ski, a sole depressor pivotable on the frame from an inoperative position to a sole-engaging operative position about a pivot shaft disposed behind the heel transversely to the length of the ski, a first spring biassing the sole depressor to its operative position, a locking arm disposed in the pivoting plane of the sole depressor and carried at one end portion by said sole depressor, a clamping lever disposed in the pivoting plane of the sole depressor and pivoted to said frame member about a pivot pin parallel to said pivot shaft, said clamping lever containing a hole through which said locking arm passes with little play and said clamping lever being biassed by a second spring towards said one end portion of the locking arm so that the clamping lever normally assumes a clamping position in which the locking arm is canted in the hole, and a handle for deliberately freeing the sole depressor for movement to the inoperative position by acting on the clamping lever to pivot same against the action of said second spring to a releasing position in which the locking arm is not canted in the hole.
Claim 2
Dependent Claim
216 words
A mounting device for the heel of a ski boot in a ski binding for a ski, comprising a frame member securable to the ski, a sole depressor pivotable on the frame from an inoperative position to a sole-engaging operative position about a pivot shaft disposed behind the heel transversely to the length of the ski, a first spring biassing the sole depressor to its operative position, a locking arm disposed in the pivoting plane of the sole depressor and carried at one end portion by said sole depressor, a clamping lever disposed in the pivoting plane of the sole depressor and pivoted to said frame member about a pivot pin parallel to said pivot shaft, said clamping lever containing a hole through which said locking arm passes with little play and said clamping lever being biassed by a second spring towards said one end portion of the locking arm so that the clamping lever normally assumes a clamping position in which the locking arm is canted in the hole, and a handle for deliberately freeing the sole depressor for movement to the inoperative position by acting on the clamping lever to pivot same against the action of said second spring to a releasing position in which the locking arm is not canted in the hole.
Claim 3
Dependent Claim
58 words
A mounting device according to claim 1, wherein the locking arm is fixed to said sole depressor and its other end portion is arcuate with the centre of curvature at the axis of said pivot shaft, said clamping lever being mounted on the pivot pin for radially limited displacement or the pivot pin itself being displaceable within limits.
Claim 4
Dependent Claim
25 words
A mounting device according to claim 1, wherein said locking arm is pivoted to said sole depressor about an axis parallel to said pivot shaft.
Claim 5
Dependent Claim
64 words
A mounting device according to claim 1, wherein said handle is adapted to be swung to engage an abutment of said sole depressor for pivoting same to said inoperative position and wherein said handle acts on said clamping lever through a movable transmission member which is carried along by the handle to engage the clamping lever as the handle is swung towards said abutment.
Claim 6
Dependent Claim
40 words
A mounting device according to claim 4, wherein said transmission member comprises one limb of a third spring which is stronger than said second spring, is coiled on said pivot shaft and has its other end bearing on the handle.
Claim 7
Dependent Claim
51 words
A mounting device according to claim 1, wherein said clamping lever is pivoted to said frame member by way of an intermediate lever biassed to a normal position by a fourth spring against the action of which the said sole depressor is able to execute limited motion towards said inoperative position.
Claim 8
Dependent Claim
18 words
A mounting device according to claim 6, including an abutment disposed in the path of the clamping lever.
Claim 9
Dependent Claim
22 words
A mounting device according to claim 7, wherein the abutment for the clamping lever is in the form of an adjustable screw.
Claim 10
Dependent Claim
210 words
A mounting device for the heel of a ski boot in a binding for a ski, comprising a frame member securable to the ski, a sole depressor pivotable on the frame from an inoperative position to a sole-engaging operative position about a pivot shaft disposed behind the heel transversely to the length of the ski, a first spring biassing the sole depressor to its operative position, a locking arm disposed in the pivoting plane of the sole depressor and carried at one end portion by said frame member, a clamping lever disposed in the pivoting plane of the sole depressor and pivoted to said sole depressor about a pivot pin parallel to said pivot shaft, said clamping lever containing a hole through which said locking arm passes with little play and said locking arm being biassed by a second spring towards said clamping lever so that the clamping lever normally assumes a clamping position in which the locking arm is canted in the hole, and a handle for deliberately freeing the sole depressor for movement to the inoperative position by acting on the locking arm to pivot same against the action of said second spring to a releasing position in which the locking arm is not canted in the hole.
Claim 11

210 words
A mounting device for the heel of a ski boot in a binding for a ski, comprising a frame member securable to the ski, a sole depressor pivotable on the frame from an inoperative position to a sole-engaging operative position about a pivot shaft disposed behind the heel transversely to the length of the ski, a first spring biassing the sole depressor to its operative position, a locking arm disposed in the pivoting plane of the sole depressor and carried at one end portion by said frame member, a clamping lever disposed in the pivoting plane of the sole depressor and pivoted to said sole depressor about a pivot pin parallel to said pivot shaft, said clamping lever containing a hole through which said locking arm passes with little play and said locking arm being biassed by a second spring towards said clamping lever so that the clamping lever normally assumes a clamping position in which the locking arm is canted in the hole, and a handle for deliberately freeing the sole depressor for movement to the inoperative position by acting on the locking arm to pivot same against the action of said second spring to a releasing position in which the locking arm is not canted in the hole.
