Rotary attachment device for snowboards

Abstract

The present invention relates to a binding device for snowboards which allow binding a boot onto the snowboard, comprising a base plate ( 4 ) which is attached to the board by means of an anchoring disc ( 3 ) and a support plate ( 2 ) forming the support for the attachment of the boot, where said base plate ( 4 ) in turn comprises in its first section anchoring grooves ( 9 ) allowing a relative anchoring position of the support plate ( 2 ) through an anchoring part ( 6 ) and a guiding part ( 5 ) which are attached to the support plate ( 2 ) by means of bindings, said anchoring part ( 6 ) and guiding part ( 5 ) being what allow the relative longitudinal forward and backward movement for engaging and disengaging said support plate ( 2 ) with respect to the base plate ( 4 ) once the anchoring part ( 6 ) is released by releasing at least one anchoring tooth ( 7 ) belonging to said anchoring part ( 6 ) from the anchoring grooves ( 9 ) of the base plate ( 4 ) through locking means with at least one retention bolt ( 23 ) which is activated by pulling on a pulling member ( 22 ); and where when said support plate ( 2 ) reaches the relative free position by performing the longitudinal forward movement, being able to thus perform a relative rotational movement between both plates facilitated by at least one curved section both of the base plate ( 4 ) and of the anchoring part ( 6 ) and guiding part ( 5 ).

1 . Rotary binding device for snowboards comprising a base plate which is attached to the board by means of an anchoring disc, and also comprising a support plate, wherein said base plate comprises in its first section anchoring grooves, and the device further comprises a guiding part and an anchoring part which comprises at least one anchoring tooth, where said anchoring part and guiding part are attached to the support plate by means of bindings, and where said parts allow engaging and disengaging the support plate with respect to the base plate through locking means with at least one retention bolt and a pulling member; and where at least one curved section of the base plate and at least one curved section of the anchoring part and guiding part facilitates the relative rotational movement between both plates. 
     
     
         2 . Rotary binding device for snowboards according to  claim 1 , characterized in that it comprises bolt tracks, and in that the retention bolts are located in at least one section of the perimeter of the anchoring groove. 
     
     
         3 . Rotary binding device for snowboards according to  claim 1 , characterized in that the anchoring disc is connected to a first oval recess of the support plate. 
     
     
         4 . Rotary binding device for snowboards according to  claim 3 , wherein the support plate contains a second oval recess housing a cover with a male projection which is coupled to a female projection of the anchoring disc. 
     
     
         5 . Rotary binding device for snowboards according to  claim 1 , wherein the base plate has at least one lower guide track located on the outside of at least a second section of the base plate. 
     
     
         6 . Rotary binding device for snowboards according to  claim 1 , wherein the support plate contains at least one rail the shape of which is defined by the trajectory of the movement of the support plate and which extends along the surface of the support plate, with at least one engaging section at at least one end. 
     
     
         7 . Rotary binding device for snowboards according to  claim 1 , wherein the base plate contains at least one channel the shape of which is defined by the trajectory of the movement of the support plate and which extends along the surface of the base plate, with at least one engaging section at at least one end. 
     
     
         8 . Rotary binding device for snowboards according to  claim 1 , wherein the guiding part comprises an upper guide track, and in that said guiding part further has a tongue located on the outer side of at least one section of the perimeter of said guiding part. 
     
     
         9 . Rotary binding device for snowboards according to  claim 1 , wherein the anchoring teeth are located in at least one inner section of the perimeter of the anchoring part. 
     
     
         10 . Rotary binding device for snowboards according to  claim 1 , wherein the base plate comprises a movement delimiting member. 
     
     
         11 . Rotary binding device for snowboards according to  claim 1 , wherein the base plate comprises at least one support plug. 
     
     
         12 . Rotary binding device for snowboards according to  claim 1 , wherein the support plate comprises cushioning foam.
