Brake for roller skis

Abstract

In one aspect, a leg activated brake for a foot supporting rolling device, such as a roller ski. Roller skis generally have one wheel mounted to each end of the foot supporting frame which houses a ski binding for the skier's boot. The brake system mounts to the frame of the roller ski and when the brake is activated by the leg, the brake applies frictional force to the rear wheel to stop the roller ski.

1 . A roller ski comprising: an elongated foot supporting platform having one or more wheels at each end of the platform, the platform having a ski binding for the users ski boot. A roller ski with a leg activated pivotal brake structure which, when leg activated, provides sufficient frictional force to the rear wheel to stop the ski.  
   
   
       2 . The rolling device of  claim 1 , with at least two articulated members, joined in such a manner that when the leg pushes against the structure the structure pivots backward.  
   
   
       3 . The rolling device of  claim 1 , with at least two articulated members, where one member has a brake pad which contacts the rear wheel when the leg activates the pivotal structure.  
   
   
       4 . The rolling device of  claim 3 , where the brake pad can be moved vertically to accommodate various wheel sizes.  
   
   
       5 . The rolling device of  claim 3 , where the brake pad is of a minimum hardness of Rockwell 50C.  
   
   
       6 . The rolling device of  claim 2 , where the upper articulated member is configured to capture the back of the leg when the leg is pushed against the brake.  
   
   
       7 . The rolling device of  claim 1 , with a spring loaded pivotal structure configured so that when in the locked upright braking position, the structure can only be pivotally moved in the direction of the rear wheel.  
   
   
       8 . The rolling device of  claim 2 , where the uppermost member of the structure can be rotated in the pivotal connection of the adjoining member to fit the skiers leg anatomy and when properly adjusted, be suitably fastened to the adjoining member to form an integral unit.  
   
   
       9 . The rolling device of  claim 2 , where the upper member has more than one position for connecting the adjoining lower member.  
   
   
       10 . The rolling device of  claim 1 , where the braking structure is mounted to the top, or to the sides, of the roller ski foot supporting platform.  
   
   
       11 . The rolling device of  claim 7 , where the pivotal structure can be unlocked and the brake structure folded over the foot supporting platform.
