A braking control device for skates including a shoe having a toe portion at a forward location and a heel portion at a rearward location, and a pivoting quarter, and the shoe being connected with a chassis having a plurality of wheels at least one of which interacts with a brake device. The braking control device has structure allowing to transfer a braking force to the at least one wheel up to a presettable value, which is preferably close to the value required to lock the at least one wheel and beyond which an excess force is substantially not transferred to the at least one wheel. The brake device includes: a traction element connected at a first end to sliding trapezoidal elements which activate pivoting breaking bars engageable with wheel hubs, and the traction element being connected at a second end with a cylinder which is slidably accommodated in a seat provided at the rear of the shoe; and a pin protruding from the quarter of the shoe for engaging a disk which is slidingly seated in the cylinder and biased upwardly by a spring. Alternatively, the cylinder is slidingly accommodated in a seat formed in the quarter of the shoe.
A braking control device, particularly for skates comprising a shoe having a quarter and associated with a chassis having a plurality of wheels, at least one of said wheels interacting with brake means, wherein it comprises means allowing to transfer energy to said brake means up to a presettable value, which is preferably close to the value required to lock said wheels and beyond which an excess energy is dissipated, said brake means comprising a cable, provided with a portion passing below a flat base of said chassis and connected, at one end approximately at said wheels, to trapezoidal elements which can slide in an interspace between said base and a straight profile of a bar which is pivoted to a first rod at one end and can slide, at the other end, in a slot formed on a second rod, said first and second rods protruding below said base and said bar interacting at an underlying hub of each of said wheels, said cable, proximate to the rear end of said chassis, being slidingly associated at an adapted sheath associated at said shoe and then curved so that the tip faces the heel region of the user.
A brake device in a roller skate having a shoe and a quarter pivoted to the shoe and wheels rotatably supported below the shoe, the brake device comprising:
