Definitions

  • the present invention relates to a roller skate, and in particular of the in-line wheel type, constituted by a chassis comprising an upper plate on which is adapted to be fixed the sole of a shoe and comprising a lower longitudinal part on which the castors or wheels.
  • This type of skate can be intended for the training of skaters on ice, except skating rink, but also for all sportsmen wishing to maintain or improve on a hard, tarred, cemented ground, ... etc. the techniques used in sliding sports such as downhill skiing, cross-country skiing, ice skating, ... etc.
  • the object of the present invention is to provide a simple and inexpensive construction allowing height adjustment of the wheels without having to resort to additional parts and making it possible to avoid the above drawbacks.
  • the invention relates to a shoe of the in-line wheel type constituted by a chassis comprising an upper plate on which a shoe is capable of being fixed and comprising a lower part on which the wheels are arranged, characterized in that at least one of the wheels comprises means for adjusting the height of said wheel relative to the chassis, which are constituted by at least one eccentric zone interposed between the hub of said wheel and a fixed part of the chassis, and carried by the hub itself so as to modify the running surface of the wheels on the ground according to the skater, depending on the type of skating to be practiced, by simply pivoting said hub.
  • the means for adjusting the height of said wheel are constituted by two end zones of the hub of said wheel, which are an integral part thereof, which are offset from the axis of said hub, and which are capable of bearing, in a chosen orientation, in the corresponding housings of the fixed part of the chassis.
  • the height of the wheels can be adjusted without adding or manipulating intermediate parts, by simply removing the wheel hub and turning it over. - even by 180 ° rotation, of said hub with eccentric ends.
  • 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 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 chassis 5 on which the wheels are arranged 6, soles from which extends a rod 7, covering the entire foot and generally extending in the direction of the skater's ankle.
  • the sole 3 of the shoe 2 is made integral with said horizontal upper plate 4 by means of fixing means, such as screws, or by riveting, bonding, etc..
  • the chassis 5 also includes a lower part extending perpendicular to the plate 4, and constituted for example by two vertical lateral wings 10 parallel to each other.
  • the lateral wings 10 are extended respectively at their upper parts by a perpendicular return, each of them being directed inward 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 mounted a plurality of wheels 6, for example four in number, the wheels being mounted by means of central hubs 11 of axis XX 'secured to the chassis 5 to constitute a running train.
  • At least one of the wheels 6 comprises means for adjusting the height relative to the chassis 5 which are formed by eccentric zones interposed between the ends 12 of the central hub of said wheel 6 and a fixed part of the chassis 5 so as to modify the running surface of the wheels 6 on the ground at the discretion of the skater, depending on the type of skating to be practiced.
  • the adjustment means are provided on the two central wheels, they could also be provided on each of the end wheels.
  • the means for adjusting the height of said central wheels 6 are constituted by two end zones 12 of the central hub 11 forming an integral part thereof, which are eccentric with respect to its axis XX ' and are likely to bear, in a chosen orientation, in corresponding fixed housings 13 formed in the inner wall of the chassis 5.
  • the eccentrics 12 forming the end zones of the hub 11 of each wheel 6 are constituted by two opposite lateral end faces 12a, 12b, arranged on the same diametrical axis DD ' wheel 6, and located relative to the center 0 of the hub thereof, at different distances, so that according to the direction of mounting of the eccentrics 12 in the corresponding fixed housings 13 of the chassis 5, the wheel 6 concerned found offset or not in height, relative to the chassis 5.
  • each of the eccentrics are inscribed in a circle whose radius is less than that of the cylindrical hub 11 of the wheel 6, and whose center 0 'is offset from the center 0 of the hub according to the offset value "h" to be obtained.
  • each eccentric 12 is the same as the circle in which the hub 11 is inscribed.
  • the rounded end faces 12a, 12b, of each eccentric 12 are delimited by two parallel and symmetrical flats 12c, 12d, relative to the diametrical axis DD 'of said faces 12a, 12b.
  • each fixed housing 13 of the chassis 5 intended for positioning the eccentric 12 of the wheel hubs 6 is formed by a vertical groove of width l substantially equal to the width l 'of the eccentric between the two flats 12c, 12d, and open at its lower part to allow the introduction of said eccentric.
  • Each housing 13 forms at its upper part a stop of rounded profile 13a corresponding to that of the opposite end faces 12a, 12b, of said eccentrics 12.
  • the means for immobilizing each wheel 6 relative to the chassis 5 are constituted by threaded holes 14 made at each front end of the eccentric parts 12 of the hub 11 of wheels 6 and intended to be put in gaze of corresponding fixed holes 15 made on each lateral wing 10 of the chassis 5 and opening out inside the groove 13, whatever the chosen position of the eccentric 12 from where the wheel 6, in order to allow the passage of a fixing screw 16.
  • the means for immobilizing each wheel 6 with respect to the chassis 5 are constituted by a screw 17 passing through a hole 18, formed in one of the lateral wings 10 of the chassis 5, in look of a cylindrical hole 19 passing right through the hub 11, so that the screw 17 passes freely through it and comes to be screwed into a threaded hole 20 of the other side flange 10 of the chassis 5, whatever the chosen position of the eccentric.
  • the length of the hub 11 of wheels 6, eccentric 12 included is substantially less than the spacing of the internal faces of the positioning grooves 13 of said eccentrics 12 so as to provide, when tightening the screws 16 or 17, a pressure on the inner ring of each of the ball bearings 21, carried by the means 11, via an associated bearing surface 10a of the chassis.
  • the hubs used will have a diameter of the order of at least 8mm to allow sufficient height adjustment of the wheels.
