Abstract: An angular adjustment device particularly for a snowboard binding, comprising a toothed disk which is rigidly connected to the snowboard and a supporting base for a shoe and is constituted by a plate which is slidingly associated with the base. The plate selectively interacts with means for connection to the toothed disk which allow the connection or disconnection of the disk with respect to a complementarily toothed seat formed below the base.

Abstract: Lever for sports shoes, constituted by a free lever arm, one end whereof engages an abutment associated with a first flap to be fastened. A toothed strap is freely pivoted to the lever arm and selectively interacts, in a ratchet-like manner, with a first tooth of a pawl rigidly coupled to a second flap to be joined. The strap has a larger last tooth adapted to interfere with the first tooth of the pawl. The pawl has a second safety tooth for locking the larger last tooth of the strap once it has disengaged from the first tooth, so as to prevent its extraction.

Abstract: Lever, particularly usable in ski boots of the type including a shell with which at least one quarter is associated, including a freely movable lever arm and a support which is associated with the quarter. The lever arm and the support have at least one seat for guiding at least two cables which are connected, at their ends, respectively to the quarter or to the shell and to the support. The two traction elements connect the lever arm to the support in a hinge-like manner, so as to give the lever arm the required orientation in open condition.
