Patin à roulettes selon les revendications 1 à 4, caractérisé en ce qu'il est prévu un bras de réglage (20) pivotant indépendamment du bras de prise (12) et du bras d'actionnement, de préférence autour de l'axe de pivotement (13) du levier de freinage pivotant, qui repose par son extrémité libre (43) sur la coulisse de freinage (6) coulissante et qui est en contact actif avec le bras de prise (12) par l'intermédiaire d'un élément d'ajustement, de préférence une vis d'ajustement (16"'), de telle sorte que lors d'un pivotement du bras de prise (12), celui-ci pousse l'extrémité libre du bras de réglage (20) contre la coulisse de freinage (6) coulissante.
  6. Patin à roulettes selon la revendication 5, caractérisé en ce que le bras de prise (12) est à peu près deux fois moins long que le bras de réglage (20).
  7. Patin à roulettes selon les revendications 1 à 4, caractérisé en ce qu'il est prévu un bras de réglage (20) à deux bras pivotant indépendamment du bras de prise (12) et du bras d'actionnement (11), de préférence autour de l'axe de pivotement (13) du levier de freinage pivotant, dont une extrémité libre vient en contact bout à bout avec une extrémité de la coulisse de freinage (6) coulissante et qui est en contact actif avec le bras de prise (12) par l'intermédiaire d'un élément d'ajustement, de préférence une vis d'ajustement (16'''), et dont la deuxième extrémité libre est articulée sur une tête excentrique (22) d'un levier excentrique (14) qui retient de manière permanente le bras de prise dans la position de freinage de la coulisse de freinage (6) avec sa tête excentrique (22) lorsqu'il est pivoté dans sa position excentrique.
  8. Patin à roulettes selon l'une quelconque des revendications 1 à 7, caractérisé en ce que le bras de prise présente le long de sa longueur une pluralité d'encoches (19) ouvertes vers le bord et espacées les unes des autres.
  9. Patin à roulettes selon la revendication 1, 2 ou 3, caractérisé en ce que le bras d'actionnement est formé de deux parties (11, 11') articulées l'une avec l'autre, l'extrémité d'une partie de bras d'actionnement (11') étant prolongée au-delà du point d'articulation et reposant par l'extrémité du prolongement du bras (11") sur une languette élastique (17) formée sur l'autre partie de bras d'actionnement (11) qui peut d'abord se déformer de façon élastique lors du pivotement du bras d'actionnement (11, 11') avant qu'une adhérence s'établisse entre les parties de bras d'actionnement (11, 11').
  10. Patin à roulettes selon l'une quelconque des revendications précédentes, caractérisé en ce qu'il est prévu une coulisse de freinage supplémentaire (9) indépendante de la coulisse de freinage (6), avec de préférence deux surfaces d'appui en forme de coin, au niveau de la roulette arrière, et en ce que la coulisse de freinage (6) et la coulisse de freinage supplémentaire (9) peuvent être déplacées par un levier pivotant (14) de telle sorte que dans la position excentrique du levier pivotant (14), les surfaces d'appui de la coulisse de freinage supplémentaire et les surfaces d'appui de la coulisse de freinage (6) soient retenues de façon permanente dans la position de freinage.
  11. Patin à roulettes selon la revendication 10, caractérisé en ce que la coulisse de freinage (6) et la coulisse de freinage supplémentaire (9) sont disposées de façon à coulisser dans un plan.
  12. Patin à roulettes selon la revendication 11, caractérisé en ce qu'il est prévu entre la coulisse de freinage (6) et la coulisse de freinage supplémentaire (9) un disque d'excentrique à ailettes (22', 22") qui peut pivoter autour d'un axe de pivotement (15', 15") de préférence parallèle aux axes de rotation des roulettes (5), l'écartement entre la coulisse de freinage (6) et la coulisse de freinage supplémentaire (9) augmentant lorsque le levier pivotant (14') du disque d'excentrique à ailettes (22', 22") est dans la position excentrique et diminuant lorsque le levier pivotant (14') est dans la position libre.
  13. Patin à roulettes selon la revendication 12, caractérisé en ce que le disque d'excentrique à ailettes (22') présente dans sa position excentrique des zones d'engagement (45) rectilignes.
  14. Patin à roulettes selon la revendication 10, caractérisé en ce qu'un mandrin de réglage (23) avec des épaulements en forme de coin est guidé perpendiculairement au sens de translation de la coulisse de freinage (6) et de la coulisse de freinage supplémentaire (9) entre la coulisse de freinage (6) et la coulisse de freinage supplémentaire (9) et en ce que le mandrin de réglage (23) est articulé avec la tête (22''') du levier pivotant à excentrique (14'), les épaulements en forme de coin étant appuyés, dans la position excentrique du levier pivotant à excentrique (14'), contre des surfaces d'appui (25) de forme identique et opposée de la coulisse de freinage (6) et de la coulisse de freinage supplémentaire (9), de sorte que celles-ci sont retenues de façon permanente dans la position de freinage.
