Anti-slide shoe

Abstract

The invention relates to a sole arrangement (10) for an anti-slid shoe (1). Said sole arrangement (10) comprises an upper and a lower sole member (20, 50) wherein the lower sole member (50) is vertically movable in relation to the upper sole member (20). Spike holding units (15) are arranged at the upper sole member (20) and are configured to hold spike members (8) extending in a vertical direction inside the sole arrangement (10). The sole arrangement (10) further comprises a locking system comprising spacing means (12) and a movable locking plate (30) arranged between the upper and lower sole members (20, 50), configured to control the vertical distance between the sole members (20, 50) to prevent the spike member (8) from protruding through the lower sole member (50). The spike holding unit (15) extends downwards through an opening (17) in the locking plate towards a spike opening (16) in the lower sole member (20).

Sole arrangement ( 10 ) for an anti-slid shoe ( 1 ), said sole arrangement comprising an upper and a lower sole member ( 20 ,  50 ) wherein the lower sole member ( 50 ) is positioned closer to the ground during normal use of the sole arrangement and may form an outer sole of the shoe ( 1 ), wherein the lower sole member ( 50 ) is movably arranged in relation to the upper sole member ( 20 ) allowing the lower sole member ( 50 ) to move in a vertical direction in relation to the upper sole member ( 20 ),
 at least one spike holding unit ( 15 ) configured to hold a spike member ( 8 ) in such a way that the spike member ( 8 ) extends in a substantially vertical direction inside the sole arrangement ( 10 ) and is movable in relation to the lower sole member ( 50 ),   at least one spike opening ( 16 ) in the lower sole member ( 50 ) allowing a spike member ( 8 ) arranged in the spike holding unit ( 15 ) to protrude downwards through the lower sole member ( 50 ),   a locking system comprising spacing means ( 12 ) and a movable locking plate ( 30 ) arranged between the upper and lower sole members ( 20 ,  50 ), said locking system being configured to control the vertical distance between the upper and lower sole members ( 20 ,  50 ) so as to, when set in a locked mode, prevent the spike member ( 8 ) from protruding through the lower sole member ( 50 ),   characterized in   that the spike holding unit ( 15 ) is arranged at the upper sole member ( 20 ),   wherein the spike holding unit ( 15 ) extends downwards through an opening ( 17 ) in the locking plate or at a side thereof towards the spike opening ( 16 ).   
     
     
         2 . Sole arrangement according to  claim 1 , wherein the spike holding unit ( 15 ) is provided with attachment means ( 22 ) allowing a spike to be detachably attached to the spike holding unit. 
     
     
         3 . Sole arrangement according to  claim 1 , wherein the locking plate is fixed in a vertical direction in relation to the upper sole member, preferably the locking plate is attached to upper sole member. 
     
     
         4 . Sole arrangement according to  claim 1 , wherein the spike holding unit ( 15 ) is fixed to an underside of the upper sole member ( 20 ), preferably the spike holding unit ( 15 ) forms an integrated part of the upper sole member ( 20 ). 
     
     
         5 . Sole arrangement according to  claim 1 , wherein the lower sole member ( 50 ) comprises a flexible membrane ( 4 ), wherein the spike opening ( 16 ) is arranged in the membrane ( 4 ). 
     
     
         6 . Sole arrangement according to  claim 1 , wherein the spacing means ( 12 ) are arranged between the locking plate ( 30 ) and the lower sole member ( 50 ). 
     
     
         7 . Sole arrangement according to  claim 1 , wherein a spike member ( 8 ) is attached to the spike holding unit ( 15 ). 
     
     
         8 . Sole arrangement according to  claim 1 , wherein the spike holding unit ( 15 ) comprises an inner element ( 19 ) provided with threads ( 22 ) for connection to corresponding threads of the spike member ( 8 ). 
     
     
         9 . Sole arrangement according to  claim 1 , wherein the upper sole member ( 20 ) comprises an upper part ( 20   a ) and a lower part ( 20   b ), wherein the lower part is made of a more rigid material than the upper part, wherein the two parts are moulded together. 
     
     
         10 . Sole arrangement according to  claim 9 , wherein the spike holding unit ( 15 ) forms an integral part of the lower part ( 20   b ) of the upper sole member ( 20 ). 
     
     
         11 . Sole arrangement according to  claim 1 , wherein the locking plate ( 30 ) is movable in a longitudinal direction of the sole arrangement between at least a first and a second position, wherein the spacing means ( 12 ) defines a minimum distance between the upper and lower sole members ( 20 ,  50 ) in one of these positions. 
     
     
         12 . Sole arrangement according to  claim 1 , wherein the upper sole member ( 20 ) is provided with at least one connection element ( 3   a ,  13   a ) and wherein the lower sole member ( 50 ) is provided with a corresponding connection element ( 3   b , 13   b ) configured to be connected with the connection element on the upper sole member to provide a stabilizing connection between the two sole members.
