Abstract
Abstract The device comprises an adjusting element (1) 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 (2) on the interior whereof a piston (5) is slidably mounted which acts on a fluid and a valve (11) controlling the passage opening of the fluid for varying the elastic bias developed by the adjusting element (1) as it is adusted in one direction independently from the bias applied during an adjustment in the opposite direction.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
96 words
A device for controlling the flex of a ski or the like boot, comprising a variable length adjusting element (1) associated, at the ends thereof, with two mutually movable points on a boot, said adjusting element (1) including a cylindrical body (2) on the interior whereof a piston (5) is slidably mounted to act on a fluid, characterized in that it comprises calibration means (11) adapted to vary the elastic bias. exerted by said adjusting element (1) when dimensionally adjusted in one direction independently of the elastic bias exerted when dimensionally adjusted in the opposite direction.
Claim 2
Independent Claim
96 words
A device for controlling the flex of a ski or the like boot, comprising a variable length adjusting element (1) associated, at the ends thereof, with two mutually movable points on a boot, said adjusting element (1) including a cylindrical body (2) on the interior whereof a piston (5) is slidably mounted to act on a fluid, characterized in that it comprises calibration means (11) adapted to vary the elastic bias. exerted by said adjusting element (1) when dimensionally adjusted in one direction independently of the elastic bias exerted when dimensionally adjusted in the opposite direction.
Claim 3
Dependent Claim
55 words
A device according to Claim 1, characterized in that said calibration means (11) are effective to vary the bias exerted by said adjusting element (2) when dimensionally adjusted in one direction, return means (20) being further provided effective to remove said bias during the dimensional adjustment of said adjusting element (2) in the opposite direction.
Claim 4
Independent Claim
74 words
A device according to the preceding claims, characterized in that said calibration means (11) com---prises valving means (11) controlling the passage opening for said fluid in an external circuit (10) interconnecting, externally to said cylindrical body (2), the upper chamber and lower chamber defined in said cylindrical body (2) by said piston (5), said valving means (11) being adapted to vary the pressure losses of said fluid while flowing through said external circuit (10).
Claim 5
Independent Claim
94 words
A device according to one or more of the preceding claims, characterized in that said return means (20) comprise a one way valve (20) provided in said piston (5) and being adapted to close, thus discontinuing the communication between the upper chamber and lower chamber of said cylindrical body (2), during said dimensional adjustment of said adjusting element (1) in said one direction, and to open, thus communicating said lower chamber and said upper chamber directly together through said piston (5), during the dimensional adjustment of said adjusting element (2) in said opposite direction.
Claim 6
Independent Claim
64 words
A device according to one or more of the preceding claims, characterized in that it comprises an elastic element (31) secured to two mutually movable points on said boot and adapted to exert a calibrated bias action on the mutual translation in one direction between said two mutually movable points, said adjusting element including a decelerator (40) independently adjustable of said elastic element (31).
Claim 7
Independent Claim
34 words
A device according to one or more of the preceding claims, characterized in that said elastic element (31) comprises two springs (32,33) serially arranged with respect to each other and having different elastic rates.
Claim 8
Independent Claim
102 words
A device according to one or more of the preceding claims, characterized in that said decelerator (40). comprises a cylindrical body (41) on the interior whereof a piston (42) is mounted slidably in sealed relationship which devides said cylindrical body into a lower chamber (43) and an upper chamber (44) wherein a fluid is contained, there being further provided a first one way conduit (45) interconnecting said lower chamber (43) to said upper chamber (44).and a second one way conduit (46) connecting said upper chamber (44) to said lower chamber (43), in said conduits (45,46) there being provided calibration valving means (47,48).
Claim 9
Independent Claim
50 words
A device according to one or more of the preceding claims, characterized in that said adjustable valving means (48)interposed on said second one way conduit (46)connecting said upper chamber (44) to said lower chamber (43) is effective to control the return movement to the starting position of said two points.
Claim 10
Independent Claim
70 words
A device according to one or more of the preceding claims, characterized in that said valving means (47) interposed on said first one way conduit (45) interconnecting said lower chamber (43) to said upper chamber (44) is effective to contribute to said calibrated bias action together with said elastic element (31), said calibrated bias action exerted by said valving means (47) being dependent on the force or pulse application. rate.
