Definitions

  • the present invention relates to improvements in elevator mechanisms of the type used on lorries for operating tilting buckets or the like.
  • the object of the invention is to produce such a device capable of being mounted as a superstructure on an existing chassis, and occupying a minimum height between the chassis and the bucket, while the tilting angle of the latter may be large without producing undue stresses necessitating reinforcement of the chassis.
  • An elevating mechanism comprises a tie rod pivoted at one end on the chassis of the vehicle and, at its other end, on the first apex of a triangular lever, the second apex of which pivots about an axis provided under the bucket while the third apex of this lever, preferably an obtuse angle, is mounted to rotate on one of the ends of a lifting jack, the other end of which is linked to the chassis at a point different from that of the articulation of the tie rod, so that the centre lines of the lifting jack and the tie rod intersect.
  • Such a device makes it possible to increase the leverage of the jack, particularly at the beginning of the lifting action; the lifting force is applied to the bucket while the direction of application of this force passes through the articulating point of the triangular lever on the bucket and through the point of intersection of the centre lines of the tie rod and the jack.
  • FIG. 1 is a side elevation of a lorry fitted with an elevating mechanism according to the invention, the bucket being shown in its lowest position;
  • FIG. 2 is a partial view on a magnified scale showing details of the mechanism in the process of tilting the bucket;
  • FIG. 3 shows the bucket at the end of the tilting operation
  • FIG. 4 is a view similar to FIG. 3 but showing a modification.
  • the elevating mechanism shown in FIGS. 1 to 3 is 3,363,944 Patented Jan. 16, 1968 adapted to be mounted between the chassis A of the vehicle and a tiltable bucket B which is pivotable about an axis C.
  • This mechanism is formed by three main members, a tie rod 1, a lifting jack 2 and a triangular lever 3. Only the triangular lever 3 carries a bending moment, the tie rod operating in tension while the jack operates in compresslon.
  • the lever 3 is constructed with a triangular profile, the first apex of which carries a pivot pin 4, while the second apex pivots about a pin 5, the third being provided with a pivot pin 6.
  • the triangular profile of the lever 3 has an obtuse angularity at the third apex.
  • the pin 5 pivotably connects the corresponding apex of the lever 3 with a plate on the lower face of the bucket B.
  • the tri angular lever 3 When the bucket B is in a lowered position, the tri angular lever 3 extends substantially horizontally above the chassis A the pin 4 being located forwardly of the pin 5.
  • the pin 4 is located on the front end of the tie rod 1, the other end of which pivots about a pivot pin 7 carried by the chassis A.
  • the pin 6 is located between the pins 4 and 5 and above the line which connects them. It is articulated to the front end of the jack 2, the rear end of which is pivoted on a pin 8 carried by the chassis A.
  • the shaft 8 is located forwardly of the pin 7 and at a lower level so that the axes of the jack 2 and the tie rod 1 intersect when the mechanism is viewed in elevation, as shown in FIGS. 1 to 3. Their point of intersection is displaced to a limit position shown in FIG. 3, in which the three pins 746 are approximately in alignment.
  • An elevator mechanism for tilting a bucket carried on a vehicle comprising a tie rod pivoted on the chassis of the vehicle, an extending jack pivoted on the chassis at a different point from that of said tie rod, and ahead thereof with respect to the vehicle, a triangular lever, pivot points at two of the apices thereof for said link and said jack, a tilting bucket, a pivot for the rear of said bucket, and a pivot interconnecting said bucket and said triangular lever, the locations of said pivots being such that the centre lines of said link and said jack intersect during initial bucket movement.
