Assembly for holding a foot on a sports item

Abstract

The invention relates to a hinged, adjustable assembly for holding a foot ( 33 ) on a sports item ( 40 ). The inventive assembly is characterised by a shell ( 5 ) which pivots around a shaft ( 6 ) which is fitted into a plate ( 4 ). According to the invention, two torsion springs ( 7 ), which are mounted to the aforementioned shaft, are blocked in rotation and used to maintain an adjustable pressure ( 39 ) between the shell ( 5 ) and the foot ( 33 ) which is introduced into the assembly at a curve ( 12 ). The upper raised end ( 11 ) of the shell ( 5 ) and the tensioning ( 38 ) of the torsion springs ( 7 ) enable said shell ( 5 ) to move upwards when the user wants to insert/extract a foot ( 33 ) into/from the assembly. The aforementioned plate ( 4 ) comprises a notched slot ( 19 ), which is housed in the notched slot ( 16 ) of a disk ( 3 ), and can be used to adjust the shell ( 5 ) in translation ( 35 ). Moreover, the other face of said disk ( 3 ) comprises a notched circular ring ( 13 ), which is housed in the notched circular ring ( 22 ) of the base, and can be used to adjust the shell ( 5 ) in rotation ( 36 ). Another disk ( 2 ) comprises a notched circular ring ( 23 ), which is housed in the notched circular ring ( 21 ) of the base, and can be used to adjust the device in rotation ( 34 ). The aforementioned adjustments enable the user to adjust the shells ( 5 ) to the feet ( 33 ) comfortably, using the associated pins.

1 ) Retention assembly ( 60 , 61 , 58 ) of a foot ( 33 ) on a sport item ( 40 ) of the sliding board type, characterized in that it is adjustable to the feet ( 33 ) of different users and in that it permits an instantaneous insertion and withdrawal of the feet ( 33 ). The retention assembly ( 60 , 61 , 58 ) comprises a shell ( 5 ) in pivotal connection about an axle ( 6 ) ensleeved in a plate ( 4 ) and resilient members ( 7 ) which exert a pressure ( 39 ) on the foot ( 33 ) introduced into the retention device ( 60 , 61 , 58 , 90 ), and characterized in that an upper disc ( 33 ) establishes a connection between said plate ( 4 ) and the base ( 1 ) to adjust the position of the assembly ( 3 , 4 , 5 , 6 , 7 ) relative to said base ( 1 ) and in that a lower disc ( 2 ) which retains said base ( 1 ) on the item ( 40 ) permits adjusting the position of the assembly relative to the item ( 40 ).  
   
   
       2 ) Retention assembly ( 60 , 61 , 58 , 90 ) according to  claim 1  characterized in that the raised circular curve ( 11 ) of the upper region of said shell ( 5 ), gives rise to the raising of said shell ( 5 ) during lateral introduction ( 38 ) of the foot ( 33 ) of the user into the retention assembly ( 60 , 61 , 58 , 90 ).  
   
   
       3 ) Retention assembly ( 60 , 61 , 58 , 90 ) according to  claim 1  characterized in that the circular curve ( 12 ) of said shell ( 5 ), tangent to the raised circular curve ( 11 ), completely envelopes the top of the introduced foot ( 33 ) of the user.  
   
   
       4 ) Retention assembly ( 60 , 61 , 58 ) according to  claim 2  characterized in that the torsion springs ( 7 ) are in tension ( 37 ) about the axle ( 6 ) which ensures the pivotal connection between said shell ( 5 ) and said plate ( 4 ), and permit the shell ( 5 ) to rise upon lateral introduction ( 38 ) of the foot ( 33 ) of the user into the device ( 60 , 61 , 58 ) at the level of the raised circular curve ( 11 ).  
   
   
       5 ) Retention assembly ( 60 , 61 , 58 ) according to  claim 1  characterized in that the torsion springs ( 7 ) are mounted on the axle ( 6 ) on opposite sides of the upper portion of said plate ( 4 ), with the feet ( 35 ) disposed in regions ( 30 ) of said shell ( 5 ) and the other feet ( 26 ) immobilized in rotation against said plate ( 4 ), such that they transmit an adjustable energy rotation ( 39 ) to said shell ( 5 ) when the foot ( 33 ) of the user is completely introduced into the retention assembly ( 60 , 61 , 58 ) at the level of the ergonomic circular curve ( 12 ).  
   
   
       6 ) Retention assembly ( 60 , 61 , 58 , 90 ) according to  claim 1  characterized in that said base ( 1 ) comprises on its lower portion ( 80 ), a first region in the form of a notched circular ring ( 21 ) adapted to receive the notched circular ring ( 23 ) of said lower disc ( 2 ), which permits the adjustment in rotation ( 34 ) about the axis Oz and in translation ( 65 , 66 ) of the retention assembly ( 60 , 61 , 58 , 90 ) relative to the board ( 40 ), by manipulation of the corresponding pins ( 70 ).  
   
   
       7 ) Retention assembly ( 60 , 61 , 58 , 90 ) according to  claim 1  characterized in that said base ( 1 ) comprises on its upper portion ( 81 ), a second region in the form of a notched circular ring ( 22 ), adapted to receive the notched circular ring ( 13 ) of the surface ( 85 ) of the upper disc ( 3 ), this system associated with the two circular oblong holes ( 14 ) of the upper disc ( 3 ), permits the user to adjust the position of the upper disc ( 3 ) in rotation ( 36 ) relative to the base about the axis Oy and hence permits the user to carry out an adjustment in rotation ( 36 ) of said shell ( 5 ) on its foot ( 33 ), by manipulation of the corresponding pins ( 71 ).
