Abstract: A clamping device for two telescopic tubes (1, 2) comprises a ring (7) which is longitudinally split and thus defines a longitudinal spacing (8) located in a plane intersecting the ring (7) longitudinally, said ring (7) being extended towards the outside by two wings (9, 11) facing each other on either side of the longitudinal spacing (8), at least one rod forming an axis (A) arranged transversely in relation to the plane and passing through the two wings (9, 11), and an arm (12) which is fixed and pivots in relation to the rod forming an axis (A), so as to make possible clamping of the ring (7) by reduction of the longitudinal spacing (8), the two wings (9, 11) being brought towards one another. The arm (12) is divided into two branches (13, 14) each having a free end through which the rod forming an axis (A) passes, the two branches (13, 14) and also the free ends coming to lie on either side of the two wings (9, 11) of the ring (7) in order to enclose said two wings (9, 11).

Abstract: A platform (1) for raising the binding intended for fitting on a board for gliding (4), one free end (6) of which has the ability to slide longitudinally relative to the board, which also comprises: a stud (20) intended for securing to the board (4) in order to form a fixed point; a movable member (40) capable of being displaced within the free end (6) of the platform and through the action of the user, said movable member being able to adopt two positions, namely: a “blocked” position in which it has a portion (43) abutting against the fixed stud (20), so as to prevent the movement of the end (6) of the platform relative to the stud (20); a “free” position in which it can slide freely relative to the stud (20) and thus allow the longitudinal sliding of the platform (4) relative to the stud (20).

Abstract: Cross-country ski binding for a boot equipped with two bars (61, 62), comprising a latch (2) that can be actuated by a lever (5) to hold the front bar (61) and a link rod (3) equipped with a hook (4) for catching on the rear bar (62) of the boot. The link rod (3) is urged by a tension spring (6) and is articulated to a point (26) located between the two bars of the boot, preferably on a spindle (26) secured to the latch. This construction is particularly compact and allows the boot a great deal of movement.

Abstract: The brake is constituted by a cylindrical body (18) mounted rotatably and movably radially to its axis (17) in relation to the chassis (1) of the skate so as to come into contact with the two rear wheels (4, 5) on backward flexion of the leg. The cylindrical body (18) is preferably mounted with vertical play on a lever (11) actuated by a collar (9) of the boot.

Abstract: A skate is provided, consisting of an upper chassis (3) which supports a boot (4) and which is articulated onto a lower chassis (1) provided with rollers (2), about a pin (5) located in the front half of the lower chassis. The upper chassis (3) is elastically supported. The inclination of the upper chassis (3) can be modified using an adjustment device with prepositioning, comprising a wedging part and a prepositioning member (12) that arms a spring whose relaxation brings the wedging part into the desired position when it is released by the upper chassis. A relatively weak actuation spring is sufficient.
