Sports shoe, in particular alpine ski shoe

Abstract

The invention relates to a sports shoe, in particular an alpine ski shoe, comprising an upper part and a sole formation. A stiffening element for influencing the stiffness of the sole formation extends between a toe side and a heel side of the sole formation. A detachable fixing element is assigned to the stiffening element and is exclusively disposed at the heel side of the sole formation, so that said fixing element can be operated from the entry for the user's foot into the sports shoe and in the detached state permits removal of the stiffening element from the interior of the upper part of shoe via the entry for the user's foot.

1 . A sports shoe, in particular alpine ski shoe, comprising a shell like upper part having an access opening for entry of a user's foot into the sports shoe, an inner lining at least partially accommodated in the shell-like upper part, a sole formation having a toe side and a heel side and being disposed beneath the shell-like upper part, at least one stiffening element arranged in the sole formation extending between the toe side and the heel side, and a fixing element arranged at the heel side of the sole formation to secure the at least one stiffening element in the sole formation, the fixing element being at least partially removable from the sports shoe, so that said fixing element can be operated from the access opening for the user's foot into the sports shoe and can be detached to permit removal of the stiffening element with respect to the interior of the upper part of shoe via the access opening for the user's foot. 
     
     
         2 . The sports shoe according to  claim 1 , wherein the fixing element is secured in an active state and provides a lift lock for the stiffening element with respect to the sole formation, which lift lock being provided for preventing vertically directed relative motions between the stiffening element and the sole formation. 
     
     
         3 . The sports shoe according to  claim 1 , further comprising supports at the toe and heel sides, wherein the stiffening element is supported without clearance on the supports. 
     
     
         4 . The sports shoe according to  claim 1 , further comprising a positive-locking plug connection arranged to attach the stiffening element to the support on the toe side, with said plug connection in its active state being designed in perpendicular direction with respect to the contact plane for a user's foot for preventing relative movement between the toe side of the stiffening element and the support. 
     
     
         5 . The sports shoe according to  claim 1 , wherein the support on the toe side is embodied as an integral component of the shell-like upper part. 
     
     
         6 . The sports shoe according to  claim 1 , wherein the shell-like upper part and the sole formation are embodied as an integral plastic injection molding component and form the support on the heel side as an integral component in the end section on the heel side of the sole formation. 
     
     
         7 . The sports shoe according to  claim 1 , wherein the stiffening element is directly supported on at least a portion of the sole formation. 
     
     
         8 . The sports shoe according to  claim 1 , wherein the fixing element in an active state, prevents the heel side of the stiffening element from lifting with respect to the sole formation. 
     
     
         9 . The sports shoe according to  claim 1 , wherein the fixing element is designed as bayonet connector, which allows an optional detaching and fixing of the stiffening element with respect to the sole formation by a combined plug and rotary movement of a holding pin. 
     
     
         10 . The sports shoe according to  claim 9 , wherein the bayonet connector comprises a holding pin fixed to the sole formation and essentially oriented perpendicular to a contact plane of a user's foot, and the holding element can be plugged and rotated with respect to the holding pin to create a positive-locking and detachable coupling between the holding element and the holding pin. 
     
     
         11 . The sports shoe according to  claim 9 , wherein the holding element comprises at least one supporting collar. 
     
     
         12 . The sports shoe according to  claim 9 , wherein the holding element comprises at least one positive-locking coupling medium including a slot for a connection coupled by turning motion with an auxiliary tool, and wherein the positive-locking coupling medium can be reached from an entry for the user's foot into the sports shoe. 
     
     
         13 . The sports shoe according to  claim 3 , wherein the support on the heel side has at least one bearing surface running transversely to a longitudinal axis of the sole formation, which bearing surface is oriented in an inclined manner at an angle with respect to a transverse plane oriented perpendicular to the longitudinal axis of the sole formation.
