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.
  • Such skates are generally provided with a braking device both to be able to meet safety criteria and to allow certain artistic or acrobatic figure skating figures to be produced.
  • This type of brake is very effective in making an emergency stop.
  • the object of the present invention is to remedy these drawbacks by proposing a braking device in which the friction element can be as far as possible from the ground during the rest phase and thus allow it to offer a greater braking surface, by compared to the prior art where, its proximity to the ground, required the biases given to these lateral edges as mentioned above.
  • the invention relates to a skate of the wheel or in-line wheel type comprising a shoe, the sole of which is associated with an upper plate of a chassis on which the skating wheels are arranged and having a device for braking consisting of a friction element in connection with actuating means interposed between an articulated rear part of the shoe and said friction element, so as to bring the latter into friction contact with the ground for a effective braking during a rearward tilting of said articulated part of the shoe caused by the skater, characterized in that the friction element is connected to the means actuation by means of amplification capable of increasing its stroke relative to that of said actuating means.
  • 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 intended to be made integral with the upper plate 4 of a frame 5 on which are arranged wheels 6.
  • the shoe comprises a shell 8 covering the entire foot and extending in the direction of the skater's ankle by an articulated part 7 surrounding the skater's ankle, this articulation on the shell 8 taking place via 'an axis 9.
  • the shell 8 of the shoe 2 is made integral with the horizontal upper plate 4 of the chassis 5 by means of fixing means, known per se and not shown in the drawing, such as screws.
  • the chassis 5 also comprises a lower part perpendicular to the plate 4, along a longitudinal axis, consisting for example of two vertical lateral wings 10 parallel to each other and arranged on either side of the longitudinal axis.
  • the lateral wings 10 extend respectively to their upper parts by a perpendicular return, each of them being directed towards the outside and constituting a plane corresponding to the horizontal plate 4.
  • the vertical lateral wings 10 define generally with the sole 3 of the shoe 2 an inverted U between the wings of which are arranged a plurality of wheels 6, for example four in number, via the transverse articulation axes 12, integral with the chassis 5, in order to constitute a running gear.
  • Such a shoe has a braking device consisting of a friction element 13 in connection with actuating means 14 constituted by an arm interposed between an articulated rear part 7 of the shoe 2 and said friction element 13, of so as to bring it into contact by friction with the ground for effective braking during a rearward tilting of said articulated part 7 of the shoe 2 caused by the skater.
  • the friction element 13 is connected to the actuation means 14 by means of amplification means 15, generally designated, capable of increasing the stroke of said friction element 13 relative to the stroke of the actuating means 14, this without increasing the amplitude of movement of the latter, and therefore without increasing the amplitude of movement of the collar actuated by the skater.
  • the invention therefore makes it possible to improve the braking effect without, however, requiring on the part of the user a greater tilting of the ankle towards the rear which could be detrimental to the balance of said user.
  • these means 15 for amplifying the stroke of the friction element 13 are constituted by a reduction system comprising on the one hand, a fixed rack 16 produced (or fixed) on an inner wall of a housing 7, open at its lower part and secured to a rear part of the chassis 5 by means of a fixing lug 18 extending rearwardly relative to said chassis.
  • the reduction system comprises a movable rack 19 secured to the friction element 13 by means of a fixing screw 20.
  • the movable rack 19 is housed in said housing 17 opposite the fixed rack 16.
  • the driving movement of the friction element 13 towards the ground, for a braking operation, is carried out by means of a drive pinion 21 interposed between said fixed rack 16 and said movable rack. 19.
  • the drive pinion 21 is controlled in translation between the fixed and movable racks 16 by means of the arm 14 at the free end of which it is fixed and which is in connection with the articulated part 7 of the shoe 2. From in this way, the movable rack 19, and therefore the friction element 13, is driven relative to the fixed rack 16, and therefore relative to the chassis 5, according to a value equal to that of the stroke of the link arm 14 to which is added that of the additional stroke of the movable rack 19 caused by the pinion 21 carried by the arm 14.
  • the housing 17 is of quadrangular section and comprises on each of its faces 17a, 17b, perpendicular to those 17c, 17d, carrying the racks respectively fixed 16 and movable 19, an oblong guide light 22 of an axis 23 integral of the end of the link arm 14 and on which the drive pinion 21 is rotatably mounted.
  • the rotation of said pinion 21 causes, by unwinding on the fixed rack 16, the displacement in translation of the movable rack 19.
  • the end of the link arm 14 is connected to the horizontal branch 24a of a U-shaped yoke 24 overlapping externally the closed upper part 17e of the housing 17 and the free ends of its two vertical branches 24b, 24c, constitute bearings of rotation of the axis 23 of the drive pinion 21.
  • the yoke 24 thus makes the connection between the link arm 24 and the drive pinion 21.
  • an elastic return member 25 of the friction element 13 in the initial position after braking is interposed between the horizontal branch 24a of the U-shaped yoke 24 and the upper bottom 17e of the housing 17 .
  • the elastic return member 25 is a compression spring.
  • the longitudinal axis X, X ', of the elastic return member 25 is offset in the direction of the articulated part 7 of the shoe 2 relative to the axis Y, Y', of the link arm 14 so as to ensure the support of the latter against said articulated part 7.
  • the movable rack 19 is connected to the friction element 13 via a support plane 26 whose surface is at least equal to the cross section of the housing 17 and on the end lower open which it abuts in an inactive position.
  • the drive pinion 21 of the movable rack 19 relative to the fixed rack 16 is constituted by a simple drum toothed longitudinally according to a constant diameter and extending between two faces 17a, 17b, of the housing 17 along an axis Z, Z '(cf. FIG. 3), parallel to said racks 16, 19, which have a toothing corresponding to that of the pinion 21.
  • the toothing of the pinion 21 and of said racks 16 and 19 is calculated for a selected and predetermined reduction ratio.
  • the drive pinion 21a, 21b, of the movable rack 19a relative to the fixed rack 16a is constituted by a double drum comprising a central toothed part 21a, of reduced diameter compared to the diameters of two end parts 21b also toothed, the central part 21a cooperating with a corresponding part of the fixed rack 16a of the housing 17 and the end parts 21b cooperating with corresponding parts of a movable rack 19a secured to the element friction 13, so as to obtain a gear ratio greater than that obtained with a single-toothed pinion of constant diameter, as previously described in the example of FIG. 1.
  • FIG. 4 illustrates this increased gear well in which it can be seen that according to a stroke C corresponding to the stroke of the link arm 14 and causing the rotation A of the small diameter part 21a of the pinion, a displacement B of the part of large diameter 21b of the pinion, and therefore of the movable rack 19a.
  • the stroke of the friction element 13 is not equal to the value A (equivalent to the value C) corresponding to the stroke of the link arm 14, but to the sum of the values A + B. It this is indeed an amplified race according to the invention.
