Abstract
Abstract Ski boot with a rigid or flexible sole. In a ski boot provided normally with a relatively flexible sole, there is provided a stiff insert which is interrupted in the zone of the ball of the foot and is there provided with one or more cross members. Said cross members are contoured to having easy rolling movement with respect to each other or with respect to the adjacent surfaces of the insert. Tension wires are arranged in the sole in the tension zone thereof which wires are anchored at the forward end of the boot and attached to suitable tensioning means at the heel end. These tensioning means may be manually operated or may be operated automatically by the heel binding of the ski, whereby same when actuated will hold the boot sole rigid in condition for effective skiing but when released will permit the boot its normal flexibility.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
In a ski boot having a sole which resists bending, wherein the improvement comprises a pressure-resisting and bendingresisting insert (10), of corrosion-resisting metal, is embedded entirely in the sole member (2), intO which insert, in the zone of the ball of the foot, there is provided at least one link member (11-11) which is positioned transversely over the entire width and which is profiled for rolling movement and that said reinforcing insert (10) is connected to a tensioning device which acts in longitudinal direction and can be externally operated, by means of which tensioning device the entire, reinforced sole member (2-10) is selectively during skiing fixed rigidly, selflockingly (rigid sole) or remains flexible during walking without skis.
Claim 2
Dependent Claim
117 words

Claim 3
Dependent Claim
93 words
The improvement according to claim 1, wherein the tensioning device for the hingedly assembled reinforcing insert (10) consists of two steel wires (21) which are inserted in its tension zone in a longitudinal direction, which steel wires are secured adjustably on the front end of the sole (2), and are fixedly connected, through a tensioning bar (24), on the heel end, and that this tensioning device can be locked in the extended position of the boot sole (2) by means of a lockable tensioning member (25) which cooperates with the tensioning bar (24).
Claim 4
Dependent Claim
71 words
The improvement according to claim 2, wherein the tensioning member of the tensioning device consists of a two-arm lever (25) which is supported in the heel end of the reinforcing insert (10), which engages (at 25'') on one end the steel wire (21), or the tensioning bar (24), and on the other end is held in locking position by its upwardly projecting second arm (25'''') by means of a tensioning means.
Claim 5
Dependent Claim
49 words
The improvement according to claim 3, wherein the tensioning lever (25) is held in locking position by means of a separate lever tensioning means (51-52) which is mounted on the ski boot (1) and grips around the heel and which engages the upwardly projecting lever arm (25'''') (FIG. 5).
Claim 6
Dependent Claim
48 words
The improvement according to claim 3, wherein during insertion of the ski boot (1) into the ski binding the tensioning lever (25) is held automatically in locking position by means of the heel clamp (41) of the ski binding, which heel clamp engages its upwardly projecting arm (25'''').
Claim 7
Dependent Claim
35 words
The improvement according to claim 1, wherein the sole member (2-10) which is reinforced with the metallic reinforcing insert (10) is slightly curved, concavely when viewed from above, in longitudinal direction in relaxed rest position.
