Definitions

  • Frame structure for skates with longitudinally aligned wheels.
  • This invention relates to a frame structure for skates with longitudinally aligned wheels.
  • Roller skates comprising a boot of substantially rigid plastic material, to the sole of which there is fixed a substantially inverted U-shaped frame, in the flanges of which there are mounted a plurality of horizontal pivot pins for longitudinally aligned wheeis.
  • An object of the invention is to provide a frame for skates with aligned wheels, comprising a vibration damping device which is effective but at the same time simple from the constructional and functional viewpoint.
  • Figure 1 is a schematic si ⁇ e view of a frame accor ⁇ ing to the invention with relative boot Figure 2 shows it in the same view as Figure 1 but with the wheels stressed Figure 3 shows a different embodiment thereof in the same view as Figure 1
  • Figure 4 is a front view thereof without the boot
  • Figure 5 is a longitudinal section through that part of the frame which supports the boot Figure 6 in an exploded front view of a wheel support fork
  • Figure 7 is a side view of a further embodiment of the frame
  • Figure 8 is a partly sectional side view of a frame provided with a braking device
  • Figure 9 is a partly sectional front view of a modification of the fork element and
  • Figure 10 is a side view thereof
  • the skate frame according to the invention comprises a substantially inverted U-shaped structure 2 preferady of aluminium formed from flanges 4 a plate 6 for fixing the toe of the boot 8 and a plate 10 for fixing its heel
  • the flanges 4 comprise a plurality of holes 12 of horizontal axis for engagement by pins 14 on which corresponding inverted U-shaped forks 16 are pivoted and are provided at the free ends of their arms 17 with holes 18 for engagement by pivot pins 20 for the wheels 22
  • Each fork 18 is arranged within the U-shaped structure 2 substantially with its arms inclined so that the pins 14 20 by which the fork 16 is pivoted to the structure 2 and the wheels 22 are pivoted to the fork 16 respectively are not vertically aligned with each other
  • the arm inclination can generally vary from 10° to 40°
  • Each fork arm 17 comprises a seat 32 for housing a block 34 constructed of elastomer material
  • the purpose of the block 34 is to damp the blow transmitted by the fork 16 to the frame following a stress undergone by the wheel during skate operation on encountering roughness 35 present on the ground
  • the rear wheels have their pivot pins 20 to the rear of the vertical passing through the pins 14 by which the corresponding fork 16 is pivoted to the frame, the term rear being understood with respect to the normal direction of advancement of the skate
  • the arms 17 of each fork 16 consist of two portions forming a contained angle such that again in this case the pin 20 by which the wheels 22 are pivoted to the fork 16 is not vertically aligned with the pin 14 by which the fork 16 is pivoted to the frame 2
  • FIG. 8 shows a particular braking system for the described skate frame
  • each arm 17 is provided with a peg 36 connected by a slotted annular element 38 to a further peg 40 mounted on an appendix 42 projecting lowerly from a slide 50 longitudinally slidable in suitable horizontal seats provided on the facing inner surfaces of the skate structure
  • Said appendices 42 have their lower ends corresponding in shape to the shape of the wheels and are provided with brake shoes (not shown on the drawings)
  • the distance between the pegs 36 and 40 is less than the distance between the ends of the slotted annular element 38 In this configuration the ends of the appendices 42 are spaced from the wheels If the user exerts a downward pressure on the plate 10 by means of his heel the arms 17 tend to rotate about the pins 14 the oegs 36 secured to them rotating in consequence
  • an elastic element 52 consisting for example of an elastomer pad the presence of which opposes the movement of the slide
  • the frame consists of a tubular metal section 54 fixed to the underside of the boot support plate
  • a plurality of suoport elements 60 for the wheels 22 are secured by pins 58 to the outer edges 56 of the tubular section said elements being in the shape of two opposing forks 62 74
  • the fork 62 wnich has its cavity facing downwards and supports the wheel pivot pins 64, has a first portion 66 which is vertical and a second portion 68 which is inclined to one side Between the upper surface of the horizontal portion rod 70 which connects together the arms 72 of the fork 74 pivoted to the tubular element and the tubular element itself there are provided two coil so ⁇ ngs 76 positioned on opposite sides of the pin 58 and housed in corresponding seats 78 provided in the lower surface
  • the springs 76 act as the damping means for the movements of the wheels each time these encounter ground roughness
  • a plate 82 rigid with a setscrew 84 so that on rotating the setscrew the plate is able to correspondingly compress the spring which it faces ln a different embodiment
  • the tubular section consists of a corresponding rib of rectangular cross-section projecting from the lower surface of the boot sole

Abstract

Cette structure de cadre pour patins à roues en ligne est caractérisée en ce qu'elle comprend: un cadre longitudinal (2) solidaire de façon rigide avec une chaussure, une pluralité de fourches (16, 60), dont les branches sont dirigées vers le bas, et qui sont montées pivotantes sur le cadre au moyen de broches horizontales (14, 58), une pluralité de roues (22) montées au niveau des extrémités inférieures des branches des fourches, les broches sur lesquelles les fourches pivotent et les broches sur lesquelles les roues tournent n'étant pas verticalement alignées, des moyens (28, 30) associés au cadre, afin de limiter le pivotement des fourches (16, 60) par rapport au cadre, ainsi que des éléments d'amortissement (34, 76) placés entre les branches (17, 70) des fourches et au moins une partie des moyens de rotation.
