Abstract: The device has a box-like body rotatably supporting a spool for winding one or more cables, a pivot rigidly connected to the spool, and a knob engaging the pivot in screw thread engagement relationship for actuating the spool. The pivot is connected to a toothed ring which interacts with a ratchet mechanism for preventing cable from being unwound from the spool upon a rotational movement being imparted thereto by turning the knob in one direction, and which permits cable to be unwound from the spool upon turning the knob in another direction. A pawl element has one portion which slides within a helical seat defined by a flange rigidly associated with the spool, and another portion which slides within a guide formed radially on the box-like body, for limiting the stroke of the rotational movement of the spool.

Abstract: The device includes a box-like body associated with a ski boot, an actuating knob rotatably associated with the body and acting on two winding spools adapted to wind traction elements, such as cables. The knob univocally controls the spools through mechanical reduction means. Means being furthermore provided to finely adjust the tensioning of at least one cable independently.

Abstract: The ski boot incorporating a flex control device comprises a boot shell with which a front quarter and rear quarter are associated. An interference element is provided including a wedge-like body which is active between the shell and front quarter. The wedge-like body may be positioned adjustably by means of position adjusting means operative between the shell and the quarter to adjust the bias and displacement of the front quarter relatively to the shell.

Abstract: The device for varying the inclination in ski boots comprises, on either of the two mutually movable parts of a ski boot, a detent block releasably lockable at a presettable position of said part and engageable by contact with an abutment detent defined on the other of said parts.
