Sports Shoe Comprising a Sole Provided with a Grip Enhancing Structure

Abstract

Sports shoe ( 1 ) comprising a sole ( 2 ) provided with a grip enhancing structure ( 3 ), wherein the shoe comprises at least one detector ( 51, 52 ) arranged for detecting movement of said shoe and a processor, wherein the grip enhancing structure is moveable between an increased gripping state and a decreased gripping state, wherein the processor is arranged to move the grip enhancing structure between the states based on the detected movement by said detector.

1 . Sports shoe comprising a sole provided with a grip enhancing structure, wherein the shoe comprises at least one detector arranged for detecting movement of said shoe and a processor, wherein the grip enhancing structure is moveable between an increased gripping state and a decreased gripping state, wherein the processor is arranged to move the grip enhancing structure between the states based on the detected movement by said detector, wherein the detector is arranged to detect at least one of a rotational or a translational movement of said shoe, wherein the processor is arranged to move the grip enhancing structure to the increased gripping state upon detection of a translational movement and/or wherein the processor is arranged to move the grip enhancing structure to the decreased gripping state upon detection of a rotational movement. 
     
     
         2 . Sports shoe according to  claim 1 , wherein the detector is arranged to detect a movement with a component in a plane substantially parallel to the plane of the sole. 
     
     
         3 . Sports shoe according to  claim 1 , wherein the grip enhancing structure is further moveable to an intermediate gripping state. 
     
     
         4 . Sports shoe according to  claim 1 , wherein the processor is arranged to hold the grip enhancing structure in a resting state chosen from one of the states of the grip enhancing structure, wherein the processor is arranged to move the grip enhancing structure to another state upon detection of a movement by the detector. 
     
     
         5 . Sports shoe according to  claim 1 , wherein the detector extends on the sole, wherein the detector is arranged to detect movement between the sole and a surface, in particular the ground. 
     
     
         6 . Sports shoe according to  claim 1 , wherein the detector is arranged to detect deformation of at least a part of the grip enhancing structure. 
     
     
         7 . Sports shoe according to  claim 5 , wherein the sole comprises at least a first and a second detector, wherein the detectors are arranged to detect respectively a first and a second direction of movement of the shoe, and wherein the detector is arranged to detect a translational movement if the first direction is substantially equal to the second direction and/or wherein the detector is arranged to detect a rotational movement if the first and second direction are substantially different. 
     
     
         8 . Sports shoe according to  claim 1 , wherein the detector comprises at least one piezoelectric element in the grip enhancing structure. 
     
     
         9 . Sports shoe according to  claim 5 , wherein the grip enhancing structure comprises studs, wherein at least two of the studs are provided with at least one detector. 
     
     
         10 . Sports shoe according to  claim 1 , wherein the grip enhancing structure comprises at least one piezoelectric element, wherein the processor is arranged to supply electrical signals to said piezoelectric element for moving the grip enhancing structure between the states. 
     
     
         11 . Sports shoe according to  claim 10 , wherein the piezoelectric element is arranged to change the mechanical properties of the grip enhancing structure upon receipt of electrical signals supplied by the processor. 
     
     
         12 . Sports shoe according to  claim 10 , wherein the piezoelectric element is arranged to change the structural properties of the grip enhancing structure upon receipt of electrical signals supplied by the processor.
