Definitions

• the invention relates to a roller skate, in particular an inline wheel.
• roller skates are either autonomous, that is to say independent of the shoe, or integrated, that is to say forming a single piece with the shoe.
• the invention aims to improve skates of the first category, that is to say autonomous skates.
• the invention overcomes these drawbacks.
• the skate according to the invention is characterized in that it comprises a plate provided with means of attachment, preferably of the quick type, to a shoe, a running gear comprising a chassis and wheels fixed to this chassis, and means for detachably fix the running gear to the plate.
• the removable base and undercarriage give the skate a modular character.
• This modularity brings many advantages.
• the skater may have a single plate and a plurality of running gear, two running gear differing either in the number of wheels or in the diameter of the latter.
• the plate and the running gear are configured in such a way that the running gear can be fixed indifferently in one direction or the other. In this way the skater can turn the running gear in particular to compensate for asymmetrical wear of the wheels.
• the chassis is for example constituted by a simple profile having two longitudinal walls receiving the axes of the wheels.
• the plate preferably comprises, in its lower part, at least two tabs located on the longitudinal sides of the plate.
• the removable fixing means are provided for attaching the legs of the plate to the longitudinal walls of the chassis.
• connection of the plate to the chassis is, in one embodiment, carried out in such a way that the flexibility of the plate ensures damping between the shoe and the running gear. It is also possible to provide damping means, such as “silent-block” type bodies, between the plate and the running gear.
• the plate can be fixed in variable positions relative to the running gear.
• the plane of the plate is parallel to the plane containing the axes of the wheels and, in another position, the plane of the plate is inclined relative to the plane containing the axes of the wheels. This inclination is for example directed downwards from the rear or is directed downwards from the outside.
• the plate is connected so as to be able to pivot, at a limited angle, relative to the chassis.
• braking means comprising a braking element controlled so that it comes into action, against the ground or against a wheel, when the skater exerts a tending action. to tilt the plate relative to the chassis.
• This brake control is particularly simple and ergonomic. It can be done under the effect of the skater's weight.
• the braking control means is preferably such that in normal operation, without braking control, the plate has a fixed position (not pivoting) relative to the chassis and the tilting controlling the braking is effected by an effort of the skater, who uses his weight.
• this control means there is provided, between the chassis and the plate, a leg formed by two rods, one of which is articulated to the plate and the other to the chassis; these links are hinged together, and the leg can only bend in one direction. Without control or braking force the leg remains straight.
• the brake control allows you to bend your leg. The latter returns to its upright position in the absence of braking force; preferably a spring is provided to assist in returning to the extended position of the leg.
• the braking element is either fixed to the plate or is pivotally connected to the chassis. In this way, the wheels can stay in contact with the ground when braking.
• a command for tilting the plate in the opposite direction to the tilt controlling the braking authorizes a metering of this braking.
