Sports shoe, in particular for cycling

Abstract

A sport shoe includes a first lacing strip, a second lacing strip, an intermediate strip and a closing device. The closing device includes a first winder and a second winder for stressing the first lacing strip and the second lacing strip so as to bring them closer together, and an actuator unit for selectively rotating the first winder or the second winder. The first winder, the second winder and the actuator unit are rotatably supported on a single support unit. The shoe further also includes a plug-in member of the support unit on the intermediate strip.

1 . Sport shoe, in particular for cycling, comprising a first lacing strip, a second lacing strip, an intermediate strip, positioned between the first lacing strip and the second lacing strip and a closing device, the closing device comprising:
 a first winder for a first tightening cord and a second winder for a second tightening cord, the first tightening cord and the second tightening cord each being capable of stressing the first lacing strip and the second lacing strip so as to bring them closer together by means of relative winding on the first winder and on the second winder, respectively;   selectively engageable locking devices for locking the first winder and the second winder, which locking devices are capable of preventing or limiting the rotation of the winders;   an actuator unit for selectively rotating the first winder or the second winder; wherein the first winder, the second winder and the actuator unit are rotatably supported on a single support unit, the sport shoe comprising a plug-in holding device for removably holding the support unit on the intermediate strip.   
     
     
         2 . Sport shoe according to  claim 1 , wherein the support unit comprises a box-shaped body, inside which the first winder, the second winder and the actuator unit are supported. 
     
     
         3 . Sport shoe according to  claim 1 , wherein the plug-in holding device comprise a projection and a complementary recess formed on the support unit and on the intermediate strip, respectively, or vice versa, and capable of reciprocal engagement. 
     
     
         4 . Sport shoe according to  claim 1 , wherein the intermediate strip comprises a support element, a seating being defined in the support element for housing the support unit. 
     
     
         5 . Sport shoe according to  claim 1 , comprising a first pair of cord-feed supports and a second pair of cord-feed supports, each cord-feed support of the first pair of cord-feed supports and second pair of cord-feed supports being placed on the first lacing strip and on the second lacing strip, respectively, the first tightening cord being at least partly wound around the first pair of cord-feed supports and the second tightening cord being at least partly wound around the second pair of cord-feed supports. 
     
     
         6 . Sport shoe according to  claim 1 , comprising a cord-feed seating fixed to the intermediate strip and capable of slidably holding the first tightening cord. 
     
     
         7 . Sport shoe according to  claim 1 , wherein the first winder and the second winder have parallel axes of rotation that are spaced apart in the longitudinally extending direction of the shoe. 
     
     
         8 . Sport shoe according to  claim 1 , wherein the actuator unit comprises a first gripping element and a second gripping element, which rotate together with and are coaxial with the first winder and the second winder, respectively. 
     
     
         9 . Sport shoe according to  claim 1 , wherein the actuator unit comprises a single gripping element rotatably connected to the support unit, and transmission means capable of selectively transmitting the rotation of the single gripping element to the first winder and the second winder. 
     
     
         10 . Sport shoe according to  claim 9 , wherein the actuator unit further comprises an actuating ring gear which rotates together with the single gripping element, the first winder and the second winder comprising a respective ring gear, the actuator unit being moveable on the support unit in such a way as to selectively engage the actuating ring gear with a ring gear of the first winder or a ring gear of the second winder.
