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.
Claims17
A locking and adjusting device, particularly for ski boots of the type having a substantially rigid shell and a plurality of movable portions including at least a pair of movable quarters and one movable foot presser, said device comprising:
- a box-like body rigidly associated with a ski boot;
- one first flexible traction element arranged to a first movable foot presser;
- at least one second flexible traction element arranged to actuate a respective movable quarter of the boot;
- a first spool freely pivoted to said box-like body internally thereof for winding said first flexible traction element;
- a second spool freely pivoted to said box-like body internally thereof for winding said at least one second flexible traction element;
- mechanical transmission means located internally of said box-like body for simultaneously driving said first and said second winding spools;
- - a first control knob rotatably mounted externally of said box-like body for operating said mechanical transmission means;
- tension adjustment means for finely adjusting the tension exerted on at least one of said first and said second flexible traction elements;
- whereby rotation of said first knob is simultaneously transmitted with a reduced effort of the skier to said first and said second winding spools to thereby univocally adjust the tension exerted on said first and at least one second flexible traction element, and whereby operation of said tension adjustment means allows said first and said at least one second flexible traction elements to be locked at different tension values.
A tensioning and locking device, particularly for ski boots of the type having a substantially rigid shell movably supporting at least one inner foot presser and a pair of quarters, said device comprising a box-like body fixed to said boot shell, a first traction cable for actuating said at least one foot presser, a second traction cable for actuating one first movable quarter, a third traction cable for actuating a second movable quarter, a first winding spool for winding said first traction cable, a second winding spool for simultaneously winding said second and said third traction cables, mechanical transmission means for simultaneously driving said first and said second winding spool, a first control knob for operating said mechanical transmission means, wherein said mechanical tansmission means comprise a pinion partially supported internally of said box-like body, said pinion having an outer end connected to said first control knob and the other end toothed to form a first toothed wheel, a second toothed wheel being coaxially associated with said first winding spool, a third toothed wheel being coaxially associated with said second winding spool, said second and said third toothed wheels having a diameter smaller than that of said first toothed wheel and being in mesh engagement therewith, and wherein said device further comprises controllable ratchet means interengageable with at least one of said first and second winding spool to allow rotation thereof in a winding direction of said first and at least one second traction cables while preventing accidental unwinding thereof, whereby rotation of said operating knob is simultaneously transmitted with a reduction ratio to said first and said second winding spools in said winding direction to thereby univocally lock said first and said at least one second traction cable in any desired position.
