Definitions

  • the present invention relates to an elastic assembly of a rail on a support, not involving screwing means for tightening the rail on the support.
  • the elastic fasteners of rails constituted by leaf springs, for example, described in French patent No. 2,411,920 and its certificate of addition No. 2,426,770, in which the springs are bent parallel or perpendicular to the axis of the rail, ensure the fastening of the rail on its support by tensioning the blade between a support on the shoe of the rail and a support on the support.
  • This tensioning is traditionally carried out by means of a nut screwed onto a bolt passing through the blade via a hole, and sealed or anchored by any means in the support.
  • a washer is placed between the nut and the blade to distribute the pressures on the latter.
  • screwed fasteners present the risk of over-tightening, insufficient tightening or accidental loosening.
  • FR-A-2096274 has proposed, for example, an elastic assembly of a rail on a support, of the type comprising a spring means such as a blade capable of exerting pressure on the shoe of the rail by means of an intermediate element and cooperating with a valet-shaped holding element, anchored in the support in the vicinity of a rear part or heel of the blade, said blade bearing on the intermediate element and the holding element vertically bearing on the blade so as to allow the insertion of the intermediate element and the blade under the holding element, in a direction parallel to the rail.
  • a spring means such as a blade capable of exerting pressure on the shoe of the rail by means of an intermediate element and cooperating with a valet-shaped holding element, anchored in the support in the vicinity of a rear part or heel of the blade, said blade bearing on the intermediate element and the holding element vertically bearing on the blade so as to allow the insertion of the intermediate element and the blade under the holding element, in a direction parallel to the rail.
  • the subject of the invention is an elastic assembly of a rail on a support of the type comprising a spring-forming means such as a blade capable of exerting pressure on the shoe of the rail by means of an intermediate and cooperating element. with a valet-shaped holding element and anchored in the support in the vicinity of a rear part or heel of the blade, said blade bearing on the intermediate element and the holding element vertically bearing on the blade so to allow the insertion of the intermediate element and of the blade under the holding element in a direction parallel to the rail, characterized in that the holding element comprises in its front part an element applicable to the blade, by its part or lower surface which has a boss or circular shapes forming a boss cooperating with a hollow imprint of corresponding shape, of the blade in order to prevent longitudinal and t of the latter.
  • the intermediate element and the leaf spring form a unitary assembly by virtue of a hollow housing of trapezoidal shape provided on the intermediate element and with two snaps.
  • the intermediate element and the leaf spring can constitute a unitary part obtained by molding the intermediate element in which the leaf spring is incorporated.
  • the holding element consists of an insert comprising in its middle part an element intended to receive a stop for lateral positioning of the rail.
  • the intermediate element constitutes an insulating case in which is threaded at least partially the leaf spring.
  • the leaf spring has a horizontal part threaded into the case mentioned above and extended by a curved S-shaped part cooperating with the holding element.
  • the aforementioned leaf spring forms at its free end a circular part comprising two inclined surfaces directed downwards and cooperating with corresponding surfaces of the aforementioned element of the holding element to put the blade in tension under the effect of a thrust exerted on the blade, parallel to the rail.
  • the element of the middle part of the insert has two lateral parts, the inner faces of which form a dovetail and cooperate with corresponding surfaces of the stop to prevent vertical movements of this stop.
  • the retaining element comprises a rebate serving as a reaction support for the rear part or heel of the leaf spring and the support side of which is located at a constant distance from the underside of the upper element of the holding element.
  • the device according to the invention comprises a rail 1 supported by a cross member or support 2 by means of an elastic sole 3 disposed between them.
  • the lateral position of the rail is ensured by an intermediate element 4 which abuts on the one hand, against the pad 5 of the rail 1 , and on the other hand against a shoulder 6 of the support 2.
  • This intermediate element 4 comprises two wings 7 and 8 respectively partially enveloping the shoe 5 of the rail 1 and the shoulder 6 of the support 2.
  • a spring leaf 9 applies a vertical force directed from top to bottom on the intermediate element 4 and thus builds on it.
  • the blade 9 is held on the intermediate element 4 to form therewith a unitary assembly, on the one hand in a horizontal position, thanks to a recess of trapezoidal surface formed by rims 4a of the intermediate element 4, and on the other hand in a vertical position by two snaps 4b.
  • the snaps 4b can be produced by ultrasonic forging of two bosses after positioning of the blade 9 on the intermediate element 4.
  • the intermediate element can be made of insulating material, such as polyamide or the like.
  • the blade-insert assembly 9, 4 to constitute a unitary piece can be produced by the molding of the intermediate element 4 with the leaf spring 9 taken as an armature, the leaf spring 9 then being incorporated during the molding operation with the intermediate element.
  • the blade 9 is held by one or more flanges 4c bent horizontally on the blade 9 towards the rear part 9a thereof.

  • the lower recess 13, anchored and sealed inside the support 2, is partly active in the pull-out resistance of the insert 10.
  • the upper recess 12 allows the passage of a gripping means intended on the one hand, for the handling of the support 2 during its manufacture, and on the other hand for the exact positioning of the support 2 relative to the rail 1.
  • the two sails 11 are made integral with each other by through a rebate 15 and a circular element 17.
  • the rebate 15, parallel to the rail, constitutes a dihedral whose horizontal face 16 is in the same plane as the upper face 14 of the support 2 and serves as a reaction support for the rear part or heel 9a of the blade 9.
  • the circular element 17, located at the front of the valet on the side closest to the rail, has a horizontal lower face 18 coming into contact with the blade 9 and maintaining the latter in the working position, the valet thus taking vertically support on the blade 9.
  • a boss 19 directed towards the support and located in the center of the lower face 18 of the circular element 17 cooperates with a recess 20 of the blade 9, of corresponding shape, to prevent longitudinal and transverse displacements of this blade.
  • this distance is constant and makes it possible to obtain a very great homogeneity of the tightening of the rail on the support, by the elastic assemblies arranged along, and on either side of each rail.
  • the horizontal faces 22 and 24 of the T-shaped elements 21 are located in the same plane as the upper face 14 of the support 2.

  • a vertical movement is then applied from the bottom upwards to firmly hold the support 2 against the underside of the shoe 5 of the rail 1.
  • a vertical movement directed from top to bottom is applied, inducing a vertical pressure on the blade to bring the latter into the working position and to preposition the blade-insert assembly 9, 4 in this same position, then apply a longitudinal movement parallel to the rail to the blade-insert assembly 9, 4 in order to introduce it into its final position under the holding element in the form of a valet or insert 10.
  • the elastic assembly comprises a holding element or insert 31 in the form of a valet made up of a single vertical veil 32 of appropriate sections, having good resistance to spillage under the effect of the vertical forces generated by the blade 33 in the working position.
  • the vertical veil 32 of the insert 31 is provided with an upper recess 31a and with a lower recess 31b, the latter being sealed and anchored in the support or cross 2, while the first allows, among other things, the passage of a gripping means.
