Definitions

  • the present invention relates to roller skates such as in-line skates and particularly to a braking system using as breaking means a rear wheel that rotates as long as other wheels rotate.
  • 5,505,469 shows a braking device activated by a quarter which is pivotally attached to the shoe. As the quarter rotates rearwardly a cable is activated which in FIGS. 1 and 2 tilts a block into contact with the skating surface. In FIGS. 3, 4, 5, and 6 the cable activate the movement of a braking pad 332 against the hub, and in FIGS. 7 through 12 the quarter may be moved either rearwardly or forwardly to cause a braking element to rub against the tire portion of the wheel.
  • the present invention is for a brake assembly for in-line roller skates.
  • This brake assembly has an arm which is pivotally hinged and has its forward and rearward parts at the ends of which are respectively hinged the forward and rearward bracket-shaped brake elements.
  • the rearmost wheel is pivotally connected to its preceding wheel by two link members. In this roller skate system there are five wheels in-line. The rearmost wheel plays the function of a pad like that of the brake pad braking system.
  • FIG.l shows a side view of an in-line roller skate partly in cross-section at the rear part of the skate.
  • FIG.2 shows a top view of a cross-section at the rear part of the skate.
  • FIG.3 shows a side view of a cross-section of U-shaped channel of arm in which are positioned the heads of the bracket-shaped brake and of the plate spring.
  • FIG.4 show a top view of a cross-section at the rear part of the skate without the brake assembly.
  • FIG.5 shows a side view of a cross-section at the rear part of the skate in a braking posture.
  • FIG.6 shows a view of the elements being accommodated within the U- shaped channel and the way how they are accommodated.
  • FIG.7 shows a side view of a cross-section of the portion where the torsion springs are anchored.
  • the in-line skate of this invention includes a boot 1, a chassis 2, wheels 3, wheel 14 and wheel 15.
  • Wheel 14 is pivotally connected to wheel 15 through link members 9 at points 23.
  • Arm 4 is pivotally hinged at point 16.
  • Bracket-shaped brake 5a and plate spring 13a are connected to arm 4 at point 18a and bracket-shaped brake 5b and plate spring 13b are connected to arm 4 at point 18b.
  • Limiting element 6 is fixed to frame 50 underneath the boot.
  • Torsion springs 8 are anchored to chassis 2 on both sides at points 10. The ends of springs 8 are attached to forward ends 19 of link members 9.
  • Limiting elements 20 are fixed to both sides of chassis 2.
  • Torsion spring 7 is anchored to point 17 on chassis 2 and its end is attached to the rear part ofarm4 at point 31.
  • arm 4 has a U-shaped channel 30 on both sides of its ends.
  • the opposing walls of each channel 30 have opposing holes 34 co-axially positioned on both sides of each channel 30.
  • Bracket-shaped brakes 5a and 5b have a hole 35 at their head 33.
  • Plate springs 13a and 13b have a hole 36 at their head 32.
  • bracket-shaped brake 5 and plate spring 13 are accommodated within the opposing sides of inner walls of U- shaped channel 30 by screw 27 which has two nuts 25 and 26 positioned to rear face surface of outer walls of U-shaped channel 30.
  • the head 32 of plate spring 13 is positioned within the inner walls of U-shaped channel 30 so as its front face surface to come into contact with the inner wall of U-shaped channel 30 and the back face surface of head 32 of plate spring 13 to come into contact with the front face surface of head 33 of bracket-shaped brake 5.
  • the longitude 37 of head 32 of plate spring 13 is equal to longitude 38 of side walls of arm 4.
  • the head 32 of plate spring 13 is positioned so as its back face surface is longitudinally in-line with the back face surface of curve body 39 of plate spring 13.
  • the width 42 of head 32 of plate spring 13 is calculated so as the distance from the front face of head 32 of plate spring 13 to front face of curve body 39 of plate spring 13 to be equal to width 40 of one of the opposing walls of U-shaped channel 30.
  • the width 44 of head 33 of bracket-shaped brake 5 together the width 42 of head 32 of plate spring 13 are calculated so as their sum to be a bit smaller than the distance between the two opposing faces of inner walls of U-shaped channel 30.
  • the distance 45 from the center of the hole 35 of head 33 of bracket-shaped brake 5 to uppermost point of head 33 of bracket-shaped brake 5 is shorter than the distance 46 from the center of opposing holes 34 of U-shaped channel 30 to face of base wall of U shaped channel 30. So, the bracket-shaped brake 5 is able to swing sideways within the channel 30 like a pendulum. This movement of the head 33 of bracket-shaped brake 5 is determined by the angle of the front part of boot, lifted by the skater when braking is desired, with the skating surface.
  • the stem of screw 27 is fixed in the opposing holes 34 by two nuts 25 and 26. It is important to have two nuts in order that the force of fixing the stem of screw 27 in opposing holes 34 not directly be exerted to the rear face surface of outer walls of U-shaped channel 30 as in case of a single nut.
  • the explanation done in this paragraph is the same for each U-shaped channel 30 on both sides of arm 4.
  • arm 4 swings free over the screw 47 which is fixed on both sides of chassis 2 by two nuts 21 and 22.
  • FIG. 7 represents anchoring zone of torsion springs 7 and 8 which have the same nature. They are anchored on chassis 2 by the screws 48 fixed by nuts 49.
  • the method of use of the brake system of this invention includes a bracket- shaped brakes 5a and 5b of the same nature.
  • FIG.1 shows a non-braking posture of the skate in-line.
  • Plate springs 13a and 13b having their heads anchored in the body of screws 27a and 27b, are tensioned so as not to let the bracket-shaped brake 5a and 5b make uncontrolled movements while the skater is skating free over the skating surface.
  • the skater tilts rearward the skate by lifting the wheels 3 off the skating surface.
  • the weight of the skater is positioned over the wheels 14 and 15.
  • the wheel 14 is pivotally movable at point 23, so the weight of the skater forces the rearmost wheel 14 to move upwards while it is still in contact with the skating surface. So, the wheel 14 comes into contact with the bracket-shaped brake 5b.
  • the moment the rearmost wheel comes into contact with the bracket-shaped brake 5b it shifts arm 4 at point 18b upward position.
  • Arm 4 is pivotally hinged at point 16.
  • the forward point 18a of arm 4 is forced to swing downward position, so the bracket-shaped brake 5a comes into contact with wheel 15 and braking is applied.
  • bracket-shaped brakes 5a and 5b The shape of bracket-shaped brakes 5a and 5b is of that form that the inner walls of the bracket- shaped brakes, when braking is applied, come into contact with wheels 14 and 15 through all braking surface of bracket-shaped brakes 5a and 5b.
  • the skater wishes to stop braking, he lowers the front wheels 3, which have created a certain angle with the skating surface while braking is applied, down onto the skating surface.
  • the plate springs 13a and 13b do not let the bracket- shaped brakes 5 a and 5b do uncontrolled movements.
  • the torsion springs 10 maintain the contact of wheel 14 to skating surface while skating happens and limiting elements 20 do not permit the torsion springs 8 to pull the link members 9 above a certain level.
  • Arm 4 is returned to its open position by torsion spring 7 anchored to chassis 2 and having its end attached to arm 4, when the forward wheels 3 are brought into contact with the skating surface, after the brake elements 5a and 5b are disengaged from the wheels 14 and 15, so the torsion spring 7 pulls the backward part of arm 4 downward position and the limiting element 6 comes into contact with the forward end of arm 4 and as a result of these two events the arm 4 remains in a balanced predetermined position, as shown in FIG.1.
  • the method of this invention further includes the option of using two brakes, one on each skate.
  • the bracket-shaped brake of this invention is triggered by the skater's foot, uses the rearmost wheel on the skating surface to start braking, uses two rearmost wheels and two bracket-shaped brakes as braking means, has an effective braking area in contact with the skating surface, provides effortless braking force onto the skating surface by the disposition of the weight of the skater over the rearmost wheel, can be fitted on both skates and is of light weight.

Abstract

L'invention concerne un ensemble de freinage pour des patins à roulettes en ligne, comprenant une paire d'éléments de freinage en forme d'étriers placée par dessus les deux roues arrières de chaque patin. La roue située à l'extrémité arrière est reliée de manière pivotante à la roue qui la précède par l'intermédiaire d'éléments de liaison afin de permettre le déplacement ascendant de la roue située à l'extrémité arrière. Lorsque le freinage est souhaité, le patineur relève la partie avant de la bottine de telle sorte que le poids du patineur se reporte sur les deux roues arrières et que la roue située à l'extrémité arrière soit, à son tour, déplacée dans une position ascendante, tandis qu'elle reste en contact avec le sol et qu'elle prend appui sur l'élément de freinage en forme d'étrier. La partie arrière du bras, dans laquelle est installé l'élément de freinage, est déplacée dans une position ascendante, ce qui a pour effet d'abaisser la partie avant dudit bras dans une position descendante, entraînant l'élément de freinage en forme d'étrier jusqu'à ce qu'il entre en contact avec la roue pour permettre le freinage.
