Definitions

  • the present invention relates to a cover arrangement for a waggon according to the preamble to claim 1 and to a waggon according to the preamble to claim 8.
  • cover arrangements for waggons When transporting goods by rail, it is often desirable to cover the goods so as to protect them against moisture.
  • cover arrangements for waggons There are different types of cover arrangements for waggons.
  • the most common type is a steel-sheet super-structure with two longitudinally displaceable side doors for loading and unloading the goods. This arrangement yields a maximum opening for loading which is almost half the length of the waggon. This makes it difficult to load the loading area for certain types of goods that are elongate.
  • a common example is parcels of timber, of which three are often accommodated in the longitudinal direction of the waggon. Since only half the length of the waggon is available at a time, it will be very difficult to load the parcels of timber that are to be positioned in the centre of the waggon.
  • Another type of cover arrangement in which one has tried to solve this problem, comprises a cover which is supported by arches extending between the long sides of the waggon.
  • the arches are displaceable in the longitudinal direction.
  • more than half the space can be opened for loading by pushing the arches towards one end of the waggon.
  • at least 2/3 preferably constitute the opening, for transporting the above-mentioned type of parcels of timber, which in theory does not involve any problem.
  • the cover cloth between the arches causes a problem since it does not fold in a satisfactory, uniform manner but instead fairly randomly, above all along the sides. It is therefore very difficult to use the theoretical openability.
  • An object of the invention is to provide a cover arrangement for a waggon, said cover arrangement being of the above-mentioned cover type and having arches which are easy to push together.
  • the waggon 1 comprises a platform 3, two wheel assemblies 5 with axles 7 and axle suspensions 9, and load supports 11.
  • the load supports 11 are posts 11 which are equidistantly spaced from each other along the long sides of the platform 3 and project from the platform 3. Their purpose is to prevent the load from sliding off the platform 3.
  • the arrangement comprises two end walls 13, 14, a cover 15, cover arches 17 and members 19 for extending the cover cloth 15 between the arches.
  • the cover cloth 15 is partly cut away in Fig. 1 to illustrate how the arches 17 and the members 19 are arranged and operate.
  • the end walls 13, 14 are rigid and are made up mostly of steel parts.
  • the end walls 13, 14 are fixedly connected to the waggon 1 at either end thereof and have the same width as the platform 3.
  • Each end wall 13, 14 comprises locking means 21, 23 for releasable locking of end arches 25, 27 into sealing engagement with the end walls 13, 14.
  • Each cover arch 17, except the end arches 25, 27, comprises a tube 29 which extends arcuately from one long side of the waggon 1 to its other long side.
  • the tube 29 is bent in several places to form a roof portion 31 of a suitable shape.
  • Each of the end arches 25, 27, however, comprises in this embodiment two tubes 29 which are interconnected by means of rigid crossbars 33.
  • End pieces 35 are connected to the ends of each tube 29.
  • Each end piece 35 comprises a holder 41 and four rolls 37, 39 which are carried in the holder 41 and which are arranged in the form of a square.
  • the rolls 37, 39 can be said to engage a bar 43 which is fixed to the platform 3 and run along its longitudinal side edge.
  • Two of the rolls 37 run on top of the upper edge of the bar 43 and are formed with a central groove which receives the edge of the bar 43 for guiding and retaining the rolls 37 on the bar 43.
  • the other two rolls 39 run under the bar 43.
  • the cover arches 17 are thus displaceable along the waggon 1.
  • the cover arches 17 are covered with the cover 15, such that a covered, loadable space forms under the arches 17, and more specifically between the arches 17 and the platform 3.
  • the cover 15 is fixed to the arches 17 by means of conventional clamps 51 which are fixed to the cover cloth 15 and fitted round the arches.
  • the cover 15 is further fixed to the holders 41.
  • Each holder 41 has a lip 42 which extends obliquely downwards inwards and to which the cover 15 is attached.
  • the clamps 51 are placed such that suitable spaces are obtained between the arches 17.
  • a distance between two juxtaposed, i.e. successive, arches 17 is as great as possible for the number of arches 17 required for the entire waggon 1 to be as small as possible. This is above all important in view of the wish to provide a maximum opening in a waggon with a cover arrangement. However, it is also important when taking the cost of the cover arrangement in consideration.
  • the opening should be greater than half the length of the waggon 1, and preferably at least 2/3 of the length of the waggon 1.
  • each member 19 is arcuate and extends, like the arches 17, between the long sides.
  • the member 19 extends movably through sleeves 20 which are formed of cover cloth and which are fixed at regular intervals on the inside of the cover 15 and indicated by dashed lines in Fig. 1.
  • the distance between the arch 17 to which the member 19 is attached and the sleeves 20 through which the member 19 extends is about 1/3 of the distance between two arches 17.
  • the member 19 has for its main purpose to control the folding to be even and effective.
  • the controlling takes place by the member 19 forcing the cover cloth 15 outwards and forming an outwardly directed fold. It makes the cloth 15 on both sides of the member 19, or in front of and behind seen from the waggon perspective, fold inwards. Consequently, the cloth folds in a predetermined, flexible manner.
  • the maximum opening of the preferred, shown embodiment of the invention is about 2/3 of the length of the waggon 1.
  • each member 19 is pretensioned in a closed position, in which the end arches 25, 27 are locked in the end walls 13, 14 and the cover 15 is extended between the arches 17. This position is illustrated with the left half of the waggon in Fig. 1.
  • the member 19 applies an outwardly directed pretensioning force on the cover cloth 15.
  • the member 19 is at its ends bent in the longitudinal direction of the waggon since it is forced into its mountings 47 from the lowermost of the sleeves 20 on each side, see Fig. 4. More precisely, a first portion 45 of the member 19 is in the pretensioned position curved such that the member 19 bends away from the cover arch 17 to which it is attached.
  • the first portion 45 is positioned close to the end 47 of the member 19 and can be said to extend from the point where the member 19 leaves its mounting 47 in the end piece 35 and a distance upwards, even if the most marked curvature is positioned a distance above the mounting.
  • the first portion 45 passes upwards into a second portion 49 which is also curved, although in the opposite direction, i.e. towards the arch 17.
  • the curvature of the second portion 49 is such that the member 19 above the portion 49, i.e. from the lowermost sleeve 20 upwards, is essentially parallel with the arch 17.
  • the member 19 has corresponding first and second portions at its other end. The member thus moves away from the arch 17 seen from the end 47 towards the lowermost sleeve 20 while bending elastically.
  • the bending is at least partly elastic.
  • the first portion 45 can have a plastic, i.e. permanent bending.
  • the portion of the member 19 which is positioned between said second portions 49 is thus parallel, or largely parallel, with the arches 17 and extends along the major part of the walls 53 of the cover and along the roof 55 of the cover.
  • the first and second portions 45, 49 are straight, or essentially straight, seen sideways, and the cover cloth 15 is maximally folded.
  • the cloth 15 folds naturally inwards since the members 19 extend the cloth 15.
  • the members 19 operate in this fashion essentially along the sides of the cover.
  • the roof has owing to gravity a certain natural tendency to fold between the members 19 and the arches 17. Thanks to the operation of the members 19 on the sides, this tendency is supported to such an extent as to ensure a flexible folding also of the roof.
  • the members 19 can be designed in various ways, for instance, other materials, such as other plastics or a suitable resilient metal, other modes of attachment, such as hinged attachments or spring-biased attachments, and other geometric shapes can be used.
  • the basic thing is their function of acting, between the arches 17, on the cover cloth 15 such that it folds in a predetermined and flexible way.
  • the preferred, shown embodiment has of course its special advantages.
  • the locking means, the slide means of the arches, the connection of the end arches to the end walls etc. can be designed in a manner to be chosen by one skilled in the art.
