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.
Claims14
An in-line roller skate including at least three wheels mounted on a frame on which is secured a boot and a braking device which includes a lateral rod carrying brake pads for coming into contact with discs mounted on a lateral surface of the wheels during a braking operation, said rod being guided lengthways on the frame, return means to bring the rod into a rest position, and a control lever articulated on the skate frame, a backward movement of the boot or leg of a user allowing the lever to push the rod longitudinally forwards against return means into a wheel braking position, wherein at least one ramp on a guide path of the rod is mounted on the rod or at least on a guide member of the frame between two axles of neighboring wheels for bringing said brake pads into contact with said discs when the rod moves forwards against said return means so that the braking force imposed on the brake pads against the discs of said neighboring wheels is applied at a point of the rod in the ramp region, the rod being resilient in order to be able to bend between the brake pads in contact with the discs of said neighboring wheels to assure gradual braking, and wherein the rod carrying the brake pads is placed above axles of the wheels so that the brake pads touch an upper surface of each disc of the wheels so that at the moment of contact of the pads on the discs, the rotation of the wheels in the direction of movement of the skate can drive the rod forwards in the direction of the wheels, independently of the action of the control lever, via friction of the pads on the discs to assist braking and to cause the rod pads to clamp against the disc.
An in-line roller skate including at least three wheels mounted on a frame on which is secured a boot and a braking device which includes:
- a lateral rod carrying brake pads for coming into contact with discs mounted on a lateral surface of the wheels during a braking operation, said rod being guided lengthways on the frame,
- return means to bring said rod into a rest position, and
- a control lever articulated on the skate frame, a backward movement of the boot or leg of a user allowing the lever to push the rod longitudinally forwards against return means into a wheel braking position,
- wherein at least one ramp on a guide path of the rod is mounted on the rod in contact with at least one abutting element of guide members of the frame between two axles of neighboring wheels for bringing said brake pads into contact with said discs when the rod moves forward against said return means so that the braking force imposed on the brake pads against the discs of said neighboring wheels is applied at a point of the rod in the ramp region, the rod being resilient in order to be able to bend between the brake pads in contact with the discs of said neighboring wheels to assure gradual braking,
- wherein the rod carrying the brake pads is placed above axles of the wheels so that the brake pads touch an upper surface of each disc of the wheels so that at the moment of contact of the pads on the discs, the rotation of the wheels in the direction of movement of the skate can drive the rod forwards in the direction of the wheels, independently of the action of the control lever, via friction of the pads on the discs to assist braking and to cause the rod pads to clamp against the disc, and
- wherein said abutting element of the guide members is a housing having a complementary shape to the ramp of the rod to allow a stop to be provided for the rod in a rest position and to guide the rod in the direction of the wheels during braking.
