Abstract: An in-line roller skate with a braking device including a certain number of wheels (11) disposed longitudinally between two plates of a frame (22) of the skate. A control lever (1) articulated at the rear of the boot about a pivot shaft (19) can be actuated by a backward movement of the skate cuff. When rotating, the lower part (2) of the lever (1) pushes a rod (3) forwards and lengthways against return means (10a, 10b), said rod carrying brake pads (5) in an equal number to the number of the discs (6) placed on the wheels 8 (11) and ramps (7a, 7b) co-operating with complementary parts of the frame guiding the rod in order, during a forward movement, to bring the pads into contact with an upper part of the rotating discs. The ramps are positioned between two wheels so as to assure gentle and gradual braking.

Abstract: An in-line roller skate including a main chassis (1) supporting at least two rollers (5, 6), and an auxiliary chassis (8) which is articulated onto the main chassis and bears at least the rear roller (10). The skate includes a pair of discs (13) which are mounted so as to rotate and the frustoconical faces of which are applied onto the two rear rollers (6, 10) when the skate tilts rearward, braking being ensured by friction of the discs on the rotationally fixed parts of the skate.

Abstract: The device for fastening safely a shoe onto a snow board according to the invention includes two lateral jaws (2) carried by arms (15) mounted pivotally at their free ends on a first journal (17) perpendicularly to the plane of the board and movable in a direction parallel to this plane by the action of a resilient member (4) between a closed operative position, in which these jaws cooperate with a profiled pattern of the sole of the shoe and an open position, in which the same is released. Each jaw (2) is connected mechanically to the resilient urging member (4) via a rocking member (6) mounted in such a manner that it exhibits two stable positions, corresponding respectively to the open and to the closed position of the jaws (2).

Abstract: An in-line roller skate having a boot fixed releasably to a chassis. The fastening device uses the toggle effect and comprises a latch which is articulated to the chassis and has a point which interacts with a housing on the boot. This latch is kept engaged by the blocking of a toggle joint which can be actuated by means of a lateral lever. The boot is fixed at an opposite position (A) by a hook.The latch may be in the form of a pedal actuable by the boot.

Abstract: The roller skate is fitted with a brake comprising at least one pair of disks (16, 17) supporting, through their tapered side, the two sides of at least the rear wheel (6) when the skater displaces his or her weight backwards. Braking is effected through the friction of the disks on the wheel, i.e. through the friction of the flat side of the disks on a brake lining. In one system of operation, the disks are fitted on a support fixed to the boot and joined to a frame bearing the wheels. In another system of operation, the disks are fitted on a main frame bearing the boot and the front wheels, the two rear wheels being fitted on an auxiliary frame joined to the main frame.

Abstract: The central binding for a ski with a mounting support having separated elements includes, in its lower part, pins (6,7,8,9) which are intended to cooperate with corresponding bayonet openings (12,16,20) provided within the elements constituting the support, as well as screws (40) which are intended to cooperate with screw threads (10) provided in the elements constituting the support. This support is composed of several separated elements which are mounted on the ski (21) with spaces between them. The elements each include a rigid or semi-rigid upper plate (11,14,17) and a resilient lower plate (13,15,18).

Abstract: A safety binding of a boot on a ski, which comprises two lateral clamps (1) displaceably mounted under the effect of a resilient member between a closed service position, in which the clamps cooperate with the sole of the boot, and an open position. Each lateral clamp is pivoted at the end of an arm (12) on a pivot axle (14) perpendicular to the plan of the ski, said arm being itself pivotaly mounted by its other end on an axle (13) perpendicular to said plan of the ski.

Abstract: The present invention relates to a safety binding of a boot on a ski which comprises two lateral jaws (2) mounted for movement under the force of an elastic member (5) between a closed service position in which these jaws coact with the sole of the boot (C) and an open position. It also comprises structure (3) interacting with the heel of the ski boot and having a sole grip member (29) mounted for movement by the force of the same elastic member between a service position in which this member maintains the rear end of the sole of the boot on the ski and an open position, the whole being so arranged that the opening or the closing of the lateral jaws effects the opening or the closing respectively of the sole grip member, and vice versa.

Abstract: A ski binding comprising two lateral clamps (4, 4') mounted displaceably under the action of a resilient member parallel to the plane of the ski (3) between a closed position in which the clamps coact with the sole of the boot and an open position. These clamps have when viewed from above a forwardly converging shape flaring rearwardly; the portion of each clamp adapted to coact in closed position with a medial portion of the sole of the boot forms a ramp that makes with the plane of the ski an acute angle increasing from the front (.alpha.) to the rear (.beta.). These clamps are carried by arms pivotally mounted on the ski behind the clamps. The ski boot (8) adapted to be maintained in operative position on a ski by the above binding comprises a sole (9) whose medial portion (10) has lateral edges forming ramps (11) corresponding to those of the clamps of the binding.

Abstract: The present invention relates to a safety binding of a boot on a ski comprising two lateral clamps (4) movably mounted under the action of an elastic member (28) parallel to the plane of the ski (3) between a closed position in which the clamps coact with the sole of the boot and an open position. Each clamp (4) is connected to one end of a longitudinally slidable strip (45) by means of articulatedly interconnected rods. The other end of the strip coacts with a crank (29-30) subjected to the action of the resilient member, whereby this crank has two stable positions corresponding to the respective open and closed positions of the clamps.

Abstract: The present invention relates to a brake device for skis which comprises two lateral arms (1, 1') resiliently connected to each other by a spring loop (2) and each bearing as a result of this resilient action against an incline (4, 4') forming an angle with the upper surface of the ski and which has an element (6) secured to the ski. The spring loop connecting the two lateral arms serves as a lever and is adapted to be actuated by the boot to control the movement of the arms between an active position, in which they extend below the sole of the ski (7) and are outwardly directed from the latter, and an inactive position, in which they are retracted substantially parallel and above the lateral edges of the ski.
