  DEVICE FOR TILTING A GARBAGE CONTAINER TO

  THE INTERIOR OF A DUMP FOR A GARBAGE COLLECTION VEHICLE.

  The invention relates to a device for tilting a garbage container towards the inside of the bucket of a garbage removal vehicle. This device is of the type comprising a pair of guide rails capable of being approached and distant from the bucket of the garbage removal vehicle and a carriage, mobile on said rails, provided with means for

  grabbing said garbage container and releasing it.

  Several solutions have so far been proposed for discharging the contents of a garbage container into the bucket of a garbage removal vehicle. However, these known solutions have certain drawbacks of

different nature.

  The known solutions of the type referred to above require, to achieve the tilting of a container, the use of means

  which are of complicated construction,

expensive and expensive.

  The object of the present invention is to provide a device by means of which the tilting of a container is carried out in an easy and reliable manner, solely by the effect of lifting

of a cart.

  - 2 - More particularly, the device according to the invention, of the type comprising a pair of guide rails capable of

  to be approached and removed from the body of a pick-up vehicle

  garbage container, and a mobile carriage along said guide rails, provided with gripping means and release of a garbage container, is characterized in that said guide rails comprise a curved end portion provided with stops end, said carriage comprising pairs of rollers capable of cooperating with said guide rails, one of said pairs of rollers cooperating with said stops for tilting the carriage

  as a result of the uprising.

  According to an important characteristic of the invention, said guide rails have a cross section in C consisting of a flat and a wing placed in opposition with this flat, a first pair of said rollers cooperating with said flat and said opposite wing, and a second pair of said rollers

  cooperating only with said plate, the first pair of rollers-

  your being arranged so as to overcome the second pair, the latter being carried at the ends of the uprights of a frame or chassis provided with pads controlled to move on the guide rails by a driving means, advantageously a

  hydraulic cylinder and cable system.

  The invention is shown schematically, by way of

  non-limiting example, in the accompanying drawings, in the-

  which: FIG. 1 is a front view of the lower part of a device according to the invention; Figure 2 is a side view of the device, when mounted on the bucket of a garbage removal vehicle; Figure 3 shows the device in the lowered position and in the raised (tilting) position; and - 3 - Figures 4, 5 and 6 are sectional views along the

  lines A-A, B-B and C-C in Figure 3.

  Referring to the figures, there is shown a device generally designated by 1, which comprises a pair of guide rails 2 mounted on a bucket 3 of a vehicle by means of a connection

  in pantograph 4. Device 1 is liable to move

  cer, under the effect of a control cylinder 6, from a first position next to the bucket 3 which allows dumping

  in it garbage contained in a garbage container

  res 5, up to a second position which allows the grip and

  return to position of said container 5.

  The guide rails 2 have a cross section in C each defining a flat or sliding surface 7 and an opposite wing 8, the two rails being interconnected by intermediate spacers 9 and base 10, the latter

  serving as a support for a hydraulic cylinder 11. The extremi-

  upper tees of the guide rails 2 have a part

curved 12.

  The rod 13 of the cylinder 11 carries a pair of pulleys 14 around which pass cables 15 having one end anchored at 16 on said cylinder 11 (FIG. 3) and the other end anchored

  on a chassis or frame 17 associated with a generally designated carriage

generally by 18.

  This carriage 18 comprises a first pair of oppo-

  sées 19 intended to roll in the guide rails 2 between the rail elements 7 and 8 (FIG. 6), a second pair of opposite rollers 20 intended to roll in the guide rails 2, but only in contact with the flat element 7 of

  these rails (Figure 6) and a third pair of oppo-

  sées 21, also intended to roll in the rails 2, only in contact with the flat element 7 thereof (Figure). The frame 17 carries, on each side of this frame, a shoe 22 intended to slide on the guide rails 2 between the rail elements 7 and 8 (FIG. 4), each shoe 22 being secured to one end d an upright 23 of the frame 17, the other end of which is articulated at 24 on the carriage 18,

  the articulation 24 having the same axis as the roller shafts-

your 20.

  As can be seen in FIG. 3, the curved part 12 of each guide rail 2 carries a stop 25 capable of cooperating with a nose 26 presented by the carriage 18, as well as an appendage 27 intended to cooperate with a corresponding cavity 28 formed close to the nose 26. An arched stop

29 is also planned.

  In the illustrated embodiment, the gripping device of a container 5 by the carriage 18 is generally designated by the reference 30; this device has not been illustrated in detail, because it is capable of being produced in a way

any known.

  During operation, the cylinder 11-being actuated causes the extension at the outlet of the rod 13, which results in a traction exerted on the cables 15, therefore a displacement

  up the frame 17 and the pads 22. These pads 22 push

  then feels upwards the carriage 18 through the uprights 23, said carriage 18 being at this stage in abutment by all of its wheels 19, 20 and 21 on the flat elements 7 of the rails 2 and being prevented from overturning towards outside by

  the engagement of the wheels 19 with the wings 8 of said rails.

  At the end of the uphill stroke, the pair of wheels 19 (FIG. 3) press against the arc stops 29, while, as the pads 22 continue to climb, the carriage 18 tilts (arrow F) and container 5 carried

  -by this one. It should be noted that during the rocking phase-

  -5 - ment, appendix 27 will engage in cavity 28 of the carriage

  18, which prevents it from moving in the direction

  tion of the arrow E. The engagement of the nose 26 with the stop 25 limits said tilting stroke in the direction of the arrow F. - 6 -
