Assembly for connecting a boot to a ski, and an adapter to be used in said assembly

Abstract

The invention relates to an assembly ( 1 ) for connecting a boot to a ski ( 2 ), including a binding ( 3 ) arranged to be connected to the boot, and a section ( 4 ) of the top surface ( 5 ) of the ski ( 2 ) arranged to be connected to an essentially plate-like adapter ( 6 ) between the binding ( 3 ) and the section ( 4 ), the adapter ( 6 ) being arranged to increase the distance between at least a part of the underside ( 7 ) of the binding ( 3 ) and the top surface ( 5 ) of the ski ( 2 ). A first locking device ( 9 ) is arranged on the underside ( 7 ) of the binding ( 3 ) for locking the binding ( 3 ) to the adapter ( 6 ) via a corresponding second locking device ( 10 ) on the top side ( 11 ) of the adapter ( 6 ). Furthermore, a third locking device ( 13 ) is arranged on the underside ( 12 ) of the adapter ( 6 ) for locking the adapter ( 6 ) to the section ( 4 ) via a corresponding fourth locking device ( 14 ). The first locking device ( 9 ) on the binding ( 3 ) corresponds in addition to the fourth locking device ( 14 ) on the section ( 4 ) in order to permit direct connection of the binding ( 3 ) to the ski ( 2 ) without the use of the adapter ( 6 ). The invention also relates to an adapter ( 6 ) for use in the assembly ( 1 ).

1 . An assembly for connecting a boot to a ski, including a binding arranged to be connected to the boot, and a section of the top surface of the ski arranged to be connected to an essentially plate-like adapter between the binding and the section, the adapter being arranged to increase the distance between at least a part of the underside of the binding and the top surface of the ski, comprising:
 a first locking device arranged on the underside of the binding for locking the binding to the adapter via a corresponding second locking device on the top side of the adapter;   that a third locking device arranged on the underside of the adapter for locking the adapter to the section via a corresponding fourth locking device,   the first locking device on the binding corresponding in addition to the fourth locking device on the section in order to permit direct connection of the binding to the ski without the use of the adapter, the adapter including corresponding sliding grooves and locking catches for slide-guiding to a fastening position via said sliding grooves, in order to permit locking in the sliding direction by means of snap engagement via said locking catches.   
     
     
         2 . The assembly according to  claim 1 , wherein the fastening position between the adapter and the section is adjustable in the longitudinal direction of the ski, a plurality of locking notches being provided along the length of the section for locking in a corresponding number of fastening positions. 
     
     
         3 . The assembly according to  claim 2 , wherein the fastening position between the binding and the adapter is fixed and cannot be adjusted. 
     
     
         4 . The assembly according to  claim 1  further comprising including a separate adapter for connection between the section and a separately arranged heel piece of the binding, the adapter having an essentially identical thickness along its longitudinal direction. 
     
     
         5 . The assembly according to  claim 1  wherein the adapter has a steadily diminishing thickness or wedge shape along its longitudinal direction, and diminishing from a forward part of the adapter which corresponds to a forward part of the binding, the wedge shape allowing connection of the separately arranged heel piece of the binding directly on the section without the use of adapter. 
     
     
         6 . The assembly according to  claim 1  wherein on the underside of the adapter there is provided at least one weakened portion extending transverse to the longitudinal direction of the adapter to facilitate the bending motion of the ski in its longitudinal direction. 
     
     
         7 . The assembly according to  claim 1  wherein on each side of the long side of the adapter there is arranged an edge extending in the longitudinal direction which projects sideways beyond the width of the section, a longitudinal groove being provided in the edge for sliding accommodation of a corresponding longitudinal edge on each of the respective sides of the section. 
     
     
         8 . The assembly according to  claim 1  wherein a number of weight-saving cut-outs are provided in the adapter, and where X-shaped reinforcing ribs are arranged in the cut-outs. 
     
     
         9 . The assembly according to  claim 1  wherein the adapter is made of plastic. 
     
     
         10 . The assembly according to  claim 1  wherein the section is of plastic and is integrally configured with the top surface of the ski. 
     
     
         11 . The adapter for use in an assembly as disclosed in  claim 1 .
