Definitions

  • the present invention relates to a roller skate assembly with a braking device, equipped with a system for compensating the wear of the brake pad.
  • the pad When the user tilts the shoe backwards or forwards, respectively, depending on the brake type, the pad interacts with the ground and performs braking.
  • the support on which the pad is mounted is integral or rigidly coupled with the rest of the wheel-supporting frame and, as the pad wears down, the user, in order to brake, must tilt the skate more and more, with consequent difficulty in keeping balance.
  • European Patent Application EP 687 487 proposes a system for adjusting the distance of the braking surface of the brake pad relative to ground, so as to compensate the pad wear.
  • the brake pad is secured to a pivoting support pivotally connected to the rest of the skate so as to pivot about the rotation axis of the rearmost skate wheel.
  • the tilt of the pivoting support is adjusted by an assembly of two toothed bars or levers and a locking cam lever.
  • the cam lever may spontaneously unlock while the skate is being used, or it can be too stiff and difficult to open while keeping the skate on.
  • the cam locking system requires, for a good operation, considerably precise working tolerances. Such a difficulty increases if the skate is to be manufactured by molding and generally at low cost as a mass product.
  • FIG. 2 is a side view of the skate of FIG. 1 , with the locking lever in locked condition;
  • FIG. 3 is a side view of a detail of the locking lever of the wear compensation system of the skate of FIG. 1 ;
  • FIG. 4 is a perspective view of the heel portion of the skate of FIG. 1 .
  • reference numeral 1 generally denotes a roller skate with in-line wheels according to an embodiment of the present invention.
  • in-line wheels is to be intended as meaning that wheels 9 enabling the skate to roll on ground T are arranged in a single row parallel to the rolling direction of the same wheels.
  • Skate 1 comprises a boot or skate shoe 3 and a bogie frame, generally denoted by reference numeral 5 , arranged to secure and support shoe 3 on its top portion.
  • Bogie frame 5 also defines, in its bottom portion, a bogie portion 7 to which there are secured a plurality of wheels 9 , enabling skate 1 to rest and roll upon the ground, a floor or another rolling surface T.
  • lever 21 By pivoting about rotation axis AL ( FIGS. 3, 4 ), lever 21 can reversibly move from an unlocking position ( FIG. 1 ), in which support 19 freely rotates about rotation axis AR of rearmost wheel 9 relative to the rest of bogie frame 5 , to a locking position ( FIG. 2 ), in which such rotation of support 19 is prevented.
  • lever 21 To move from the locking position to the unlocking position, lever 21 turns in a so-called “unlocking” direction, that is, with reference to the views of FIGS. 1 and 2 , it turns in clockwise direction, as shown by arrow FL 1 .
  • lever 21 Conversely, to move from the unlocking position to the locking position, lever 21 turns in a so-called “locking” direction, that is, with reference to the views of FIGS.
  • Locking lever 21 and fastening slots 23 are so shaped that they mutually engage so as to substantially prevent a mutual pivotal movement between pad support 19 and the rest of bogie frame 5 due to the push of pad 17 during braking.
  • locking lever 21 and fastening slots 23 are moreover so shaped that, due to the push of pad 17 during braking (arrow FS in FIG. 2 ), locking lever 21 is pushed further in the locking direction, or at least is maintained in the locked condition, against the portion of support 19 adjacent to lever 21 itself.
  • lever 21 and support 19 are so arranged and shaped that pad support 19 , when it tends to rotate to become lifted and presses against tooth 25 inserted in a slot 23 during braking, causes tongue 27 to rest against support 19 itself, thereby preventing further counterclockwise rotation of lever 21 and hence further clockwise rotation of support 19 .
  • the forces applied by support 19 to lever 21 in locked condition and during braking produce a resultant moment on lever 21 tending to more strongly fasten the lever to support 19 .
  • locking tooth 25 has an height H ( FIG. 3 ) that substantially is not lower than about 2 mm. More preferably, height H of locking tooth(s) 25 is not lower than about 3 mm. Still more preferably, height H of locking tooth(s) 25 is not lower than about 4 mm.
  • locking tooth 25 or another locking projection 25 of movable fastening member 21 , has a contact surface 31 onto which pad support 19 pushes during braking thereby discharging the braking forces.
  • contact surface 31 is so arranged, more particularly inclined, that the resultant of the forces applied to it by support 19 tend to rotate the tooth downwards or, more generally, to push tooth 15 towards the locking position.
  • the resultant of the forces applied to contact surface 31 by support 19 passes in a space region between rotation axes AL of lever 21 and AR of pad support.
  • tooth 15 improve the fastening reliability.
  • wear compensation system 13 In use, wear compensation system 13 , and in particular lever 21 , is in its locking position illustrated in FIG. 2 .
  • the user lifts locking lever 21 by its fingers, by grasping it by means of grasping tongue 27 and turning it upwards, with reference to FIGS. 1 and 2 .
  • Tooth 25 comes out of fastening slot 23 in which it was inserted, and releases pad support 19 .
  • the user can now turn pad support 19 in counterclockwise direction about the pivotal axis of the support (which, as said, coincides in the present example with the rotation axis of rearmost wheel 9 ) so as to bring the pad closer to ground T to the extent the user deems suitable for compensating the size reduction caused by wear, and to bring tooth 25 in correspondence of the most suitable fastening slot 23 .
  • return spring 29 FIG.
  • the different fastening slots 23 are arranged at a suitable mutual spacing, corresponding to a wear amount that is optimum for a new positioning of pad support 19 by means of the compensating device.
  • pad 17 has one or more notches or other marks, each corresponding to a pad wear limit whose attainment makes it advisable, according to the manufacturer, to move pad support 19 to a new position by means of the compensating device.
  • movable fastening member 21 may be equipped with a suitable recess, opening or hole in place of tooth 25 or other kind of projection. Furthermore, movable fastening member 21 may rest against pad support 19 , or another fastening part 23 , not only by means of grasping portion 27 but also by means of a different kind of suitably shaped projection or recess. While in the example of FIG. 3 locking lever 21 is indicatively Y- or fork-shaped, in other embodiments it may have a different shape, e.g. an L, T, cross or more or less rounded shape.
  • lever 21 may move from the locked to the unlocked condition, and vice versa, not only through a rotation relative to each other and relative to the rest of bogie frame 5 of the skate, but also through a translational or roto-translational movement.
  • lever 21 has a single tooth 25 , but in other embodiments it may have multiple fastening teeth or projections 25 , e.g. two, three or four teeth or projections.
  • Return spring 29 may be replaced by a different return member, e.g. a different kind of resilient member.
  • brake pad 17 and pad support 19 may be integrally formed as a single piece, for instance by simultaneous molding.
