Definitions

  • the present invention relates to a skate of the roller or in-line type comprising a shoe, the sole of which is associated with an upper plate of a chassis on which the skating wheels are arranged.
  • This type of brake is very effective for performing an emergency stop but it has a big disadvantage for beginners or inexperienced skaters because it requires lifting all the wheels of the skate except the last one on which the skater stays balanced.
  • the braking block is mounted articulated on the chassis and is brought in action against the ground by an arm connected to the shoe collar.
  • the purpose of the present invention is to remedy the various drawbacks which have just been mentioned by allowing an experienced skater to brake effectively, while allowing a beginner or inexperienced skater to brake also easily but while retaining a certain stability.
  • the invention achieves a compromise between the two solutions mentioned above by making it possible to keep a larger number of wheels on the ground during braking, this being effected by lifting the other part of the wheels of the undercarriage. wheels.
  • the invention also makes it possible to reduce the lifting height of the front of the pad necessary for braking, as will be seen below.
  • the present invention also relates to the characteristics which will emerge during the description which follows and which should be considered in isolation or according to all their possible technical combinations.
  • the inline skate 1 designated as a whole and partially shown in Figure 1, comprises a shoe 2 consisting of an outer sole 3, intended to be made integral with the upper plate 4 of a frame 5 on which are arranged the wheels 6, sole 3 from which extends a rod covering the entire foot and extending in the direction of the skater's ankle.
  • the sole 3 of the shoe 2 is made integral with the frame 5 forming the horizontal upper plate 4 on which said sole 3 is fixed by means known per se and which will not be described here because they are not the subject of the present invention.
  • the chassis 5 has at its rear part a braking block 7 which is integral with it and which is capable of coming into contact by friction with the ground for effective braking, by an action in lifting the front of the skate , caused by the skater.
  • the brake block 7 can be made removable by means of fixing screws so as to allow its interchangeability in the event of wear.
  • Such a skate according to the invention also comprises means for limiting the angular movement of the first part 5A of the chassis 5 relative to the second 5B, so as to not allow the pivoting of the part 5A of the chassis 5 relative to the second part 5B only in one direction, starting from an alignment position of all the wheels 6A, 6B, when they are in contact with the ground, to a lifting position chosen according to the efficiency braking desired.
  • the means for limiting the angular movement of the first part 5A of the chassis 5 relative to the second 5B consist of a stop 8 integral with said first part 5A and arranged on the latter so as to be in contact with a corresponding stop part 9 of the second part 5B when all the wheels 6A, 6B, of the skate are aligned on the ground.
  • a stop 8 integral with said first part 5A and arranged on the latter so as to be in contact with a corresponding stop part 9 of the second part 5B when all the wheels 6A, 6B, of the skate are aligned on the ground.
  • the chassis 5 comprises an elastic return member 10 of the first part 5A of the chassis 5 relative to the second part 5B, or of the second part 5B relative to the first part 5A in an anti rotation direction -time of this second part relative to their mutual axis of articulation 11 so as to bring all the wheels back into alignment once the braking phase has ended.
  • Said elastic return member 10 is arranged in corresponding zones of said parts 5A, 5B, of chassis 5 situated behind their articulation 11.
  • the second auxiliary part 5B or C1 of the chassis 5, carrying the two rear wheels 6B is constituted by a metal yoke mounted inside the main chassis part 5A.
  • This second auxiliary part 5B connects the two rear wheels 6B to the chassis.
  • This connection takes place via a part of the hinge pin 11 simultaneously passing through said main chassis part 5A and the lateral flanks of the yoke constituting its auxiliary part 5B, in an upper zone of the latter.
  • This axis 11 is preferably arranged in the extension of the axis of the tibia of a user for more stability.
  • connection is made on the other hand by means of two axes of rotation 12, 12A, of the two rear wheels 6B crossing free lower zones of the sidewalls located opposite.
  • the three axes 11, 12, 12A ensure both the connection of the two rear wheels 6B to each other and relative to the main chassis part 5B, via its auxiliary part 5A.
  • Braking with such a pad is effected by causing an upward rotation of the part 5A of the chassis 5 relative to its part 5B.
  • the brake block 7 then comes into contact with the ground, for effective braking while retaining good stability, since the two rear wheels 6B are always in contact with the same ground.
  • FIGS. 3 to 5 show particularly well the braking principle and the advantages provided by a chassis 5 as described above.
  • FIG 3 there has been shown a one-piece chassis as known in the prior art and with which it is necessary to brake to raise the front wheel O4 by a value H1, H1 representing the distance to the ground from the axis of said wheel O4. In this case, only the rear wheel O1 remains in contact with the ground.
  • Lifting the front wheel O4 by a value H1 corresponds to bringing the brake F into contact with the ground, initiating braking.
  • Figure 4 shows a skate according to the invention in the skating phase, and the four wheels O1, O2, O3, O4, are in contact with the ground.
  • the rear wheels O1 and O2 are mounted on an auxiliary chassis part C2 which is itself articulated on the main chassis part C1 by the hinge pin D.
  • the auxiliary part C2 of the chassis is therefore movable relative to its main part C1, because it has the possibility of pivoting about the axis D.
  • the braking stability thus obtained using the pad according to the invention will be all the greater when the axis D of articulation is aligned with the tibial axis of a user.
  • the invention is of course not limited to the type of skate described but can be applied to any sporting article having to solve the same problem.
