Definitions

• the invention relates to a roller skate, in particular an in-line skater, with a brake device that can be actuated from the shoe.
• US-A-5 403 021 shows a roller skate with a braking device, which has a recess in a sole, via which pressure can be exerted on a brake lever with the front toes.
• This brake lever is pivotally fixed at the rear end of the shoe and the braking device acts on the front rollers of the roller skate.
• roller skates The disadvantage of these roller skates is that, on the one hand, the braking force is very difficult to meter and the deceleration places additional strain on the front rollers of the roller skate, although the front rollers of this roller skate are loaded by the brake lever, so that the roller skater can easily move the Control of the roller skate loses, especially since it is unable to control the roller skate, as this would require the front rollers, which are currently being used for the deceleration.
• a roller skate with a braking device in which a slidable in the direction of the extension of the shoe Rod with brake blocks on the middle two rollers of a total of four rollers can be braked.
• the operation of this type of brake is relatively difficult since the driver has to move the push or brake rod forwards or backwards with his toes, which in practice is hardly possible even for the experienced driver.
• a cross-country scooter is known from DE-A-2924778, which comprises a relatively complicated and complex braking device, but because of its size it cannot be integrated into a roller skate.
• the first lever acts on an actuating device which acts on a brake body which can be moved in the direction of at least one of the rear rollers in order to bring it into operative connection with the at least one roller.
• the interaction of the first lever with the actuating device, in particular a second lever, both levers being mounted in a central region via an axis of rotation makes it possible, on the one hand, to apply the necessary actuation paths in order to carry out controlled braking, and on the other hand to make the required braking Provide braking force to brake. Since the brake body acts on the rear rollers, the front rollers do not lock and are still available to the driver for steering. In addition, the braking force applied far to the rear can help to keep the center of gravity in a controllable range during the braking process.
• the actuating device is preferably a second lever, the force arm of which can be articulated from the load arm of the first lever in order to pivot the second lever about a pivot axis in the direction of the brake body.
• the brake body is pressed against one or two rollers or their axes in order to develop the desired braking effect.
• the pivot axis is preferably above the brake body, on the one hand to take advantage of the space between the sole of the shoe and the rollers and on the other hand to keep the brake body away from the ground so that it cannot collide with bumps, which could lead to the driver falling.
• the brake body or the actuating device can, as already indicated above, individually or collectively by elastic sections or spring devices, for. B. rubber bands or the like, in the direction of a rest position in which no braking function is exercised, can be preloaded.
• the actuating device can also be designed as a cable pulling device which acts on the braking body via deflection points.
• An elastic device can be provided on the load arm of the first lever or on the power arm of the actuating device in order to be able to bring about a movement into a rest position in order to end a braking operation.
• the brake body is preferably arranged between the roller axles and the shoe sole.
• the brake release device can be designed as a pedal in the shoe compartment, or an external one be operable Bowden cable device or the like, but training as a pedal could be preferred, since em Bowden cable could be a hindrance when roller skating.
• the brake release device can be fixed or switched off by means of a mechanism, so that braking in this state is not possible or the skater's ride cannot be inhibited or disrupted by inadvertent actuation of the brake device.
• a further brake body is attached to the power arm of the first lever, which is arranged in such a way that when the pedal is actuated it acts on one or more front rollers and brakes them. This means that not only the rear rollers but also the front rollers are braked and an improved braking effect is achieved.
• This additional brake body is in the same way as the brake body assigned to the rear rollers above the rollers, i. H. arranged between rollers and shoe body.
• a further brake body extends vertically downward between the front rollers and is brought into engagement with the roller from the front. As a result, the rotating roller pulls the brake body and thus the associated power arm downwards and increases the braking effect.

• the four rollers are rotatably attached to the roller holder 4 by means of four axes of rotation 12 arranged parallel to one another and one behind the other.
• the roller skater exerts a force on a brake pedal 16 of the braking device 10 via the big toe 14 of his foot or over several or all of the toes of the foot, the rest of the skater's foot being supported on a shoe sole 3 of the shoe body 2.

• the first lever 20 is shown in perspective in FIG. 3.
• the load arm 20b of the first lever 20 is in engagement with an actuating device in the form of a second lever 24, which presses a first brake body 26 onto the two rear rollers 6 and 7 and thus brakes.

• the load arm 24b of the second lever 24 is connected to the first brake body 26 via a swivel joint 34. As soon as a force is exerted on the brake device 10 via the brake pedal 16, the first brake body 26 is moved in the direction of the rollers 5 and 7 by pivoting the lever arrangement 20, 24 relative to one another, as a result of which a braking effect is achieved.

• the pedal 16 When the pedal 16 is actuated by the toes 14, the force arm 20a is pressed down and the second brake body is also pressed down between the two front rollers 8 and 9. Since the braking force of the second brake body 36 is limited by a spring device 39 and takes place without leverage, greater braking of the front rollers 8 and 9 and the associated risk of rollover are excluded.
