Definitions

  • Object of the present invention is a closing device, in particular for containers of vehicles such as trucks or similar.
  • the invention is of the type which comprises a cover having two or more segments or rigid sheets hinged consecutively one to the other.
  • a cover having two or more segments or rigid sheets hinged consecutively one to the other.
  • it finds profitable use in raisable and/or removable containers used in the transport of materials which by their nature require particular precautions when transported, such as by-products of meat processing or more generally of materials which could be termed pollutants, possibly already closed in sealed containers (for example hospital refuse) which for safety reasons must be further sealed in rigid leak-free containers.
  • Loading of such materials is usually effected from above into appropriate containers mounted on trucks, using for said loading means which are often arranged on said trucks, or alternatively using external means such as small loading trucks, buckets, silo-type chutes etc.
  • loading on to the trucks is performed by tipping the refuse through hatches either posteriorly or laterally.
  • the primary condition to be satisfied is to be sure that there is a completely hermetic closure of the container for the polluting material, thus sealing it against exteranl agents and avoiding escape of the contents, including the emanation of any toxic fumes.
  • the present invention aims to solve the problem of how to provide a closing (and opening) system for the container which on the one hand permits of obtaining a complete hermetic closure, while on the other hand permits of removing said closure in a way which is both simple and involves the taking up of as little space as possible, to permit of an easy and sure performance of the loading and unloading operations.
  • One of the advantages provided by the invention consists in the fact that it is applicable to whatever type of container without the need for special adaptation or modification.
  • 1 indicates a container of a truck or trailer
  • 3 indicates the cover with a plurality of segments or sheets.
  • the container 1 comprises a metallic tub and is equipped with a posterior hatch 28 which is openable since it is hinged to the crossbar 2, to permit of unloading. Superiorly the container 1 is equipped with a cover, here indicated in its entirety by 3, which latter is arranged to fall into a close contact position on the upper edges of the container 1, the seal being completed by the interpositioning of a continual perimetral seal 29 on said upper edges of the container 1.
  • the cover 3 comprises two rigid sheets or segments reciprocally hinged by means of a hinge 7.
  • the posterior segment 4 is mounted to the container 1 by means of two parallel mechanisms each of which comprise an angled lever 9, two coupled cogged wheels 11 and 13 and a linear hydraulic actuator comprising a cylinder 16 which interacts between the angled lever 9 and the forked bracket 18 which is solid to the support 8 which is in its turn solid to the gearing 11 and the posterior segment 4.
  • the angled lever 9 is pivoted on the pivot 12 which is parallel to the crossbar 2 of the container 1 and coaxial to the gearing 12 solid to the crossbar 2.
  • the angled lever 9 is furthermore hinged to the posterior segment 4 by means of a second pivot 10 which is parallel to the pivot 12 and coaxial with the gearing 11.
  • the angled lever 9 is hinged to the end of the stem 15 of the hydraulic cylinder 16 whose other end is hinged to the forked bracket 18 of the support 8 by means of the pivot 17.
  • Gearings 11 and 13 having straight cogs, are similarly proportioned and arranged in such a way as to permit of correct meshing.
  • the gearings which are always enmeshed, are arranged so that gearing 11 envelops gearing 13 during rotation through the angle indicated by ⁇ in Fig.2, involving therefore a limited number of cogs only, for which reason the gearings could be equipped with only partial cogging.
  • Segment 5 is hinged consecutively to posterior segment 4 by means of a hinge 7.
  • Said segment 5 has at its anterior end two lateral and external idle wheels 19 destined to run along the lanes 20 solid to the superior lateral edges of the container 1, into which are anteriorly sunk the oblique housings 21 destined to house the idle wheels 19, one each side, when the cover is in the closed position.
  • the initial rotation of the posterior segment 4, induced by the start of functioning of the hydraulic cylinder 16 leads to the drawing of the anterior segment 5 and in particular determines the exit of the two idle wheels 19 from the housings 21 of the lanes 20 and their successive running along the lanes 20 up to the point indicated in Fig.3 where the idle wheels 19 enter exactly the housings 24 of the arms 22, said arms 22 being hinged to the upper edges of the container 1 by means of pivots 23.
  • the process of the pulling action of the hydraulic cylinder 16 determines the process of the envelopment of the gearing or sector of gearing 13 by gearing or sector of gearing 11 and thus a further clockwise rotation of posterior segment 4.
  • Said posterior segment 4 acting through segment 5, which is hinged to it, draws in rotation the arms 22, which, by climbing from the horizontal position, determine the descent of the latches 25, in this way making it impossible for the idle wheels 19 to exit from the housings 24 without blocking their relative rotation, as indicated in Fig.4.
  • the cover 3 With the complete opening of container 1, the cover 3 is therefore folded and compacted into a very small space behind the posterior hatch 28, leaving the areas behind, at the side and above the container 1 completely free.
  • the closing manoeuvre is made with the same movements in a contrary order, by means of the extension of the hydraulic cylinder 16.
  • the hermetic closing of the cover 3 is performed when the extension of the cover 3 on the container 1 is almost complete; at this point the idle wheels 19 are in proximity to the entrances of the housings 21, for which reason the final extension of the hydraulic cylinder 16 between the joint pivot 14 and the pivot 17 determines on the one hand the pressure of the posterior segment 4 on the seal 29, on the other hand the forcing of the idle wheels 19 into the housings 21, with a consequent pressure of the segment 5 on the seal 29.
  • One feature of the device illustrated is that of forming an independent group, pre-assembled inside the support 8, and therefore particularly suited to easy installation on existing tubs or containers.
  • the system permits of reaching a configuration of complete folding of the cover with very small encumbrance, and thus not creating any obstruction to the loading manoeuvre.
  • the invention also has the characteristic of permitting with a single hydraulic action, and therefore with a single manoeuvre, the closing and blocking of the cover (and the same for the opening and the unblocking).
  • two identical groups could be used side-by-side instead of a central group, to give a better distribution of the initial loads on the support structure of the posterior segment 4.
  • the base of the hydraulic cylinder 16/1 can be anchored to the bottom of the container, in the example to the posterior hatch 28, which is in its turn hinged to the pivot or pivots 12.
  • the cover 3 interacts with the posterior hatch 28 in the sense that the said hydraulic cylinder 16 /1 is able to activate the opening of the posterior hatch 28 while the cover 3 is closed, or the opening of the cover 3 while the posterior hatch 28 is closed.
  • the posterior hatch 28 has autonomous closing devices which press the hatch against the seal 30 to ensure a perfect sealed closure.
  • the closing system for the container 1 can be installed on the upper edge of one of the two sides.
  • the segments have their mutual hinging axis arranged in a longitundinal direction with respect to the container 1 itself, thus realising a lateral evolution of the device.
  • the above-described system with two segments can be added to by a third, anterior segment 6, equipped with an autonomous folding system on segment 5, for example by means of a hydraulic system 27 or equivalent systems.
  • a three-segment system could be used to permit of covering containers of greater length, without changing in any way the movement system of segments 4 and 5.
