Ski Brake

Abstract

The invention relates to a ski brake ( 1 ) for braking a ski ( 2 ) detached from a sports shoe, with a bearing device ( 3 ) for a brake lever arrangement ( 4 ) for placing on the upper side ( 5 ) of a ski ( 2 ). The brake lever arrangement ( 4 ) comprises brake levers ( 8, 9 ) arranged essentially symmetrically relative to the longitudinal middle axis ( 7 ) of the ski ( 2 ), which each have actuating arms ( 10, 11 ) and brake arms ( 12, 13 ). The brake arms ( 12, 13 ) project relative to the bearing device ( 3 ) and are pivotable over at least one pivot axis ( 15, 16 ) from a position of readiness located above the running surface ( 17 ) of the ski ( 2 ) by the force of a spring device ( 18 ) into a brake position projecting under the running surface ( 17 ). The actuating arms ( 10, 11 ) extend from the bearing device ( 3 ) in a direction facing away from the brake arms ( 12, 13 ) and are connected by a pivot bearing arrangement ( 21 ) with a foot plate ( 22 ) that can be loaded by the sole of a sports shoe. In this way an adjusting device ( 26 ) is formed whose adjusting force ( 28 ) forces the foot plate ( 22 ) continually into a pivot position ( 27 ) angled as far as possible relative to the actuating arms ( 10, 11 ).

1 . Ski brake for braking a ski detached from a sports shoe, with a bearing device for a brake lever arrangement, which is to be fitted onto the upper side of a ski, whereby the brake lever arrangement comprises brake levers arranged essentially symmetrical to the longitudinal middle axis of the ski which comprise respectively activating arms and brake arms, and whereby the brake arms project relative to the bearing device and are pivotable by at least one pivot axis from a position of readiness located above the running surface of the ski by the force of a spring device into a brake position projecting under the running surface, and whereby the actuating arms extend from the bearing device in a direction facing away from the brake arms and are connected via a pivot bearing arrangement with a foot plate that can be loaded by the sole of a sports shoe, wherein an adjusting device is formed, the adjusting force of which forces the foot plate continually into a pivot position that is angled as far as possible relative to the activating arms.  
   
   
       2 . Ski brake according to  claim 1 , wherein the adjusting device comprises an elastically flexible spring element that restores itself automatically, which is connected at its first end section to at least one spring arm of the spring device adjoining the actuating arms in one piece or directly to the activating arms and is connected at its second end section to the foot plate.  
   
   
       3 . Ski brake according to  claim 2 , wherein the spring element is designed to be essentially L-shaped and the transition section between the legs of the L-shaped spring elements is designed to be an elastically restoring deformation zone.  
   
   
       4 . Ski brake according to  claim 2 , wherein at the first end section of the spring element a coupling extension is formed for the form-closed connection with at least one spring arm of the spring device or with the actuating arms.  
   
   
       5 . Ski brake according to  claim 2 , wherein the second end section of the spring elements is secured between an upper and a lower plate part of the foot plate.  
   
   
       6 . Ski brake according to  claim 2 , wherein the spring element is formed by an injection moulded part made from an elastomeric plastic.  
   
   
       7 . Ski brake according to  claim 4 , wherein the form-closed connection is designed as a length compensation guide between the coupling extension and the spring arms or the actuating arms in their longitudinal direction.  
   
   
       8 . Ski brake according to  claim 1 , wherein the adjusting device is formed by a weight distribution of the foot plate that is uneven in relation to the pivot bearing arrangement between the foot plate and the actuating arms or by a one-sided overweight of the foot plate.  
   
   
       9 . Ski brake according to  claim 8 , wherein the front part section of the foot plate has a greater mass relative to the pivot bearing arrangement than the rear part section of the foot plate lying behind the pivot bearing arrangement.  
   
   
       10 . Ski brake according to  claim 8 , wherein the front part section of the foot plate is designed to be longer in relation to the pivot bearing arrangement than the rear part section of the foot plate lying behind the pivot bearing arrangement.  
   
   
       11 . Ski brake according to  claim 1 , wherein the adjusting device is formed by at least one permanent magnet.  
   
   
       12 . Ski brake according to  claim 11 , wherein at least one permanent magnet is secured to the foot plate in particular onto the underside.  
   
   
       13 . Ski brake according to  claim 11 , wherein a functional pair is formed from a first permanent magnet and a second permanent magnet, whereby a first permanent magnet is arranged on the foot plate and a second permanent magnet on the actuating arms or on the adjoining spring arms and said permanent magnets are in mutually repelling interaction.  
   
   
       14 . Ski brake according to  claim 13 , wherein the first permanent magnet of the functional pair is arranged in relation to the pivot bearing arrangement in the rear part section of the foot plate.  
   
   
       15 . Ski brake according to  claim 11 , wherein the at least one permanent magnet is in magnetically attracting interaction with the actuating arms or with at least one spring arm adjoining the actuating arms which is made of ferromagnetic material, in particular a steel wire.  
   
   
       16 . Ski brake according to  claim 11 , wherein the at least one permanent magnetic is arranged in relation to the pivot bearing arrangement in the front part section of the foot plate.  
   
   
       17 . Ski brake according to  claim 11 , wherein the at least one permanent magnet is secured to the actuating arms or to at least one spring arm of the spring device connected thereto and is in magnetic force effect with a foot plate consisting of ferromagnetic materials.
