Definitions

  • bearing means the whole device formed by the supporting metallic tie plate for attaching the stock rail and operating as sliding surface for the blade; locking devices of the stock rail with respect to said metallic tie plate; possible devices for facilitating the sliding of the stock rail onto the supporting metallic tie plate.
  • figure 5 depicts phases from 1 to 4, generally carried out for the insertion and assembly of such a spring 60 and then to lock the stock rail.
  • the aim of the present invention is yet to provide a bearing for switch points which solves the above-mentioned technical inconveniences.
  • Such a bearing (100, 190, 200) comprises:
  • said locking assembly further comprises a pivot (109, 195) passing at least in part through said housing (170, 180) and arranged in rotatable manner, the pivot having such an eccentricity (195) that, through a predetermined rotation thereof, said eccentricity (195) operates on the flexible element, by setting it in a load condition.
  • the eccentric pivot i.e. a cam
  • the eccentric pivot allows to set the laminar element in load condition (bending condition) in easy and rapid manner, thus allowing it to generate the locking load on the flange of the stock rail.
  • a simple counter-rotation lets such a flexible element pass to a released condition.
  • Such a support component (100) comprises a housing (170, 180) in which the element (200) can be inserted and having a transversal hole (181) intercepting at least in part said housing (170, 180) through which the eccentric pivot (190, 195) can be held.
  • the metallic tie plate 100 comprises a housing 300, according to prior art, where the stock rail is arranged (not depicted only for clarity purposes), for being locked elastically.
  • tie plate 100 comprises at the ends thereof the holes for locking bolts to the ground, as per prior art.
  • the surface 150 is obviously a flat surface, perfectly coplanar with the base of the tie plate 100. It is worked in such a manner as to have a good level of surface finish.
  • FIG. 6 depicts with number 180 the opening of such an inner housing 170, apparent in section of figure 9 , for example.
  • a transversal hole 181 (apparent from figure 6 ), intercepting at least in part the housing 170, is then obtained in the raised block forming the sliding surface 150.
  • the eccentric pivot is generally cylindrically shaped and the central area thereof, as shown in figure 7 , is provided with a suitable shaping, in order to obtain a reduction of diameter and form a tooth 195, going along the length of such a central area.
  • a tooth determines the eccentric form and so the shaping of eccentric cam in the "operative" area of the pivot.
  • such a nut-shaped head can be of any type, i.e. hexagonal, octagonal nut etc., according to the new regulations concerning nuts and bolts in general.
  • the metallic tie plate 100 comprises said opening 180, through which the leaf spring 200 can be easily inserted inside the housing, being the opening clear from any obstacle.
  • a fulcrum could be obtained also by the only shoulder 220, of adequate height, integral with the housing, i.e. obtained on the top of the housing 170.
  • This solution of fulcrum is generally applied in prior art and it is not considered optimal here with respect to the previously described one.
  • the height of the potential tooth 210 on the small elastic plate 200 would be lower than that one of the shoulder 220, in such a manner that the only shoulder or tooth 220 functions as fulcrum and with the shoulder 210 or tooth 210 with the only aim of end stroke.
  • the created system realizes a simple class 1 lever, as per prior art.
