Abstract: The device comprises a ratchet lever associated with the rear portion of the rear quarter, and coupled to a rack plate. The rack plate is longitudinally slideable on the quarter and engages with the mid-portion of a cable, connected at least one of its ends to the front quarter.

Abstract: The device comprises a lever, pivotally coupled at its upper end to a ski boot rear quarter, adapted for entraining a cable. The cable is arranged for interconnecting the front and rear quarters of a ski boot in two separate zones, spaced apart from each other along the longitudinal extension of the quarters.

Abstract: The locking device comprises an operating lever, pivotally connected to one of the elements to be brought together, and supporting a take-up spool for a joining element, connected at a fixed point to the other of the elements to be brought together. The spool is rotatable about an axis spaced from and lying substantially parallel to the pivot axis of the lever. There are also provided members for releasably blocking rotation of the spool at least in the direction of unwinding of the joining element.

Abstract: The ski boot comprises a shell to which is associated at least one quarter. An electric motor is contained in the boot and has at least a controlling portion accessible from the outside. The electric motor is electrically connected to an electric power source accommodated inside the boot and is mechanically connected with a speed reducer. The output shaft of the speed reducer is operatively associated with straps for closing the boot and/or with cables or mechanism for securing the foot inside the boot. In the controlling portion accessible from the outside, push-buttons are provided for selective actuation of the electric motor with the possibility of rotation in one direction and with the possibility of rotation in the opposite direction to vary accordingly the rotation of said output shaft.

Abstract: The present invention relates to a ski boot with a device for securing the foot of the skier. The device has the peculiarity of comprising an minicompressor associated with the boot, which can be connected to an electrical power source and operated by controls to feed compressed fluid into an inflatable chamber which can draw close to the foot of the skier for the securing thereof in said boot.

Abstract: The closure device comprises a lever having a recessed area, being articulated on the rear portion of a ski boot rear quarter and oscillable about a substantially perpendicular axis with respect to the longitudinal extension of the rear quarter and the shell. To said lever there being slidably connected a block, releasably securable on preset points of said lever and being associated with at least one cable having a fixed point on the boot's front quarter, and at least partially accommodated in the recessed area.

Abstract: This ski boot comprises a boot shell having a front gaiter and a rear gaiter associated therewith, as well as a lever element which is pivoted at one end to either of said gaiters, preferably the rear gaiter, for rotation about the pivot axis. Journalled to a middle portion of the lever element is an adjustment assembly for adjusting the working length of a pair of cables which are attached with the other ends thereof to the other gaiter, e.g. the front gaiter, at a point away from the pivot axis. The lever element may be moved to an open position, whereat said adjustment assembly is made accessible for operation and the working length of the cables can be adjusted without pulling them, and to a closed position, whereat the cables tighten the gaiters against each other, and the adjustment assembly cannot be reached from the outside.

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: A foot retaining device in a ski boot comprises a pressure element arranged within an outer shell of the ski boot at the neck area of the user's foot, and a cable embracing the pressure element and having one end fixed to the outer shell and another end wound on a winding reel operable by a knob accessible from the outside of the ski boot. The reel and knob are arranged at a rear portion of the ski boot. Rotation of the winding reel causes the pressure element to increase or decrease pressure on the user's foot. Ratchet gears are provided for retaining the winding reel and cable in position in use.

Abstract: The device comprises an adjusting element having a variable working length and being associated, at the ends thereof, with two separate and mutually movable points on a boot, the adjusting element including a cylindrical body on the interior whereof a piston is slidably mounted which acts on a fluid and a valve controlling the passage opening of the fluid for varying the elastic bias developed by the adjusting element as it is adjusted in one direction independently from the bias applied during an adjustment in the opposite direction.

Abstract: The hydraulic device comprises a pumping element which, through a selector assembly, is caused to communicate with one or more driving members provided on a boot and wherewith there is connected a respective hook element for effecting the fastening of the boot, the selector assembly being adapted to allow the releasing of one or all the fastening elements by connecting the respective driving members to a reservoir of a selected working fluid.

Abstract: The closure device comprises a box-like body associated with one of the ski boot flaps to be brought together and provided with a knob for actuating a spool whereon at least one small cable associated with the other of the flaps to be brought together is wound. Also provided is a ratchet gear mechanism driven by the knob to lock the spool at any selected position as the knob is turned in one direction, and to release the spool as the knob is rotated in the opposite direction.
