Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
Winder safety device, particularly for ski boots, comprising an operating knob (2) provided with a stem (3) rotatably associated with a supporting element (5), associable with a ski boot (6), and whereto is pivoted a winder (9, 18) for traction elements (13,21), characterized in that a drive wheel (7) is keyed to said operating knob (2) and is axially movable relatively to said stem (3) and is provided with a first gear (10) meshing unidirectionally, in the direction of winding of said traction element (9,18), with a facing second gear (14) rigidly associated with said winder (9,19), said drive wheel (7) engaging without meshing with said second gear (14) upon a rotation opposite to the one for the winding of said traction element (9,18).
Claim 2
Dependent Claim
124 words
Winder safety device, particularly for ski boots, comprising an operating knob (2) provided with a stem (3) rotatably associated with a supporting element (5), associable with a ski boot (6), and whereto is pivoted a winder (9, 18) for traction elements (13,21), characterized in that a drive wheel (7) is keyed to said operating knob (2) and is axially movable relatively to said stem (3) and is provided with a first gear (10) meshing unidirectionally, in the direction of winding of said traction element (9,18), with a facing second gear (14) rigidly associated with said winder (9,19), said drive wheel (7) engaging without meshing with said second gear (14) upon a rotation opposite to the one for the winding of said traction element (9,18).
Claim 3
Dependent Claim
58 words
Device, according to claim 1, characterized in that said stem (3) of said operating knob (2) is provided with at least one planar faceting for the coupling of said drive wheel (7), said at least one planar faceting rigidly associating in the rotation said stem (3) with said drive wheel (7) and simultaneously allowing a mutual axial motion.
Claim 4
Dependent Claim
80 words
Device, according to claim 2, characterized in that said first gear is constituted by a plurality of teeth (10), identical and equally spaced with respect to one another and having a polygonal cross section, each of said teeth (10) being provided with a first face (11) protruding perpendicular from said drive wheel (7) and at least one second face (12) connected to said drive wheel on an opposite side with respect to said first face (11), along an inclined plane.
Claim 5
Dependent Claim
83 words
Device, according to claim 3, characterized in that said second gear (14), facing said first gear (10), is rigidly associated with said winder (9, 18), the teeth (14) of said second gear being provided with a first face (15) protruding perpendicular from said winder (9, 18) and with a second face (16) connected to said winder (9, 18) along an inclined plane, respectively interacting with said first face (11) and with said second face (12) of said teeth (10) of said first gear.
Claim 6
Dependent Claim
50 words
Device, according to one or more of the preceding claims, characterized in that an elastically deformable means (8) is interposed between the facing surfaces of said drive wheel (7) and of said operating knob (2) to provide a releasable engagement of said first gear (10) with said second gear (14).
Claim 7
Dependent Claim
25 words
Device, according to claim 1, characterized in that it comprises means (17, 22) for a releasable locking of the rotation of said winder (9, 18).
