Definitions

• the present invention relates to a bottom-dump container comprising a container portion having at least two bottom doors located opposite to each other and hingedly connected to said container portion and fork tubes for supporting said container portion, said fork tubes during changing of their relative distance, by e.g. a fork truck which has an adjust ⁇ able fork distance in the horizontal plane, allow opening or closing of the bottom doors.
• the container portion now includes fewer parts than the containers mentioned above and other which are common on the market and also a much more rigid design. Furthermore the bottom doors according the invention have been integrated with the sides of the container, which results in that during dumping the lower part of the container is separated in an opposite direction so that the content is dumped very quickly and effectively.
• FIG. 1 schematically shows a perspective view of a bottom-dump container according to the present invention where the .bottom doors are in their closed position
• Fig. 2 schematically shows a perspective view of the container illustrated in Fig. 1, where the bottom doors are totally open.
• the container 1 according t a preferred embodiment according to the present inventio consists of a container portion 2 which at its lower par comprises two opposite bottom doors 4,5, which are hingedl connected to the container portion 2 by a hinge mounting i the form of a hinge 3 and fork tubes 6,7 supporting th container portion 2 and which are located at the lower par of the bottom doors 4,5 of the container portion 2.
• the for tubes 6,7 are provided to open the bottom doors 4,5 b increasing the horisontal distance of the fork tubes 6, from each other e.g.by aid of a fork truck having adjustabl fork distance in the horizontal plane.
• the horizontal distance of the fork tube 6,7 is instead decreased in a direction from each other
• the fork tubes 6,7 are preferabl integrally connected to the bottom doors 4,5 e.g. by weldin against their bottom sides 8,9.
• the fork tube 6,7 have a cross section, which does not permit turnin around the forks of a fork truck, the respective fork tub 6,7 can be hingedly connected to bottom doors 4,5 along th corner portion of the fork tubes 6,7 facing towards eac other.
• Each bottom door 4,-5 has an openig line 10, which over it extension along the hinge 3 from its ends 23 forms a border line between adjacent edge portions of the end walls 15,1 of the container portion 2 and the side walls 11,12,-13,14 o the bottom door 4,-5,said border line from a direction mainl preferably parallel to the bottom plane of the container or bottom sides 8,9 can take a direction which exten obliquely downwards up to the lower, free edge or corne portion 24 of the bottom door 4;5.
• the side walls 11,12;13,14 have a triangular design and the end walls 15,16 of the container 2 have a pointed, lower portion.
• the bottom doors 4,5 have the same size and extend over the whole length and width of the container portion 2.
• Respective bottom door 4;5 is formed by the bottom side 8;9, at the underside of which one of the fork tubes 6;7 is fixed, two opposite side walls 11,12;13,14, which are perpendicular to the bottom side 8;9, said side walls in the closed position of the bottom door 4;5 being a part of the end walls 15;16 of the container portion 2, and a connecting wall 19;20 connecting the side walls 11,12;13,14 to the bottom side 8;9 and forming lower parts of the longitudinal sides 17;18 of the container portion 2, at the upper portion of said connecting wall and at the longitudinal sides 17;18 of said conatainer portion 2 the hinge 3 is located.
• the connecting wall 19;20 on respective bottom door 4,5 has a height, which in the embodiment illustrated, is about 1/3 of the total height of the sides 17 ,18 of the container portion 2.
• a cross bar 21 articulately fixed to respective side wall 11,12;13,14 of the bottom doors 4;5 near the hinge 3, the one end of the cross bar 21 being directly articulated in the upper portion of one of the side walls 11,12 while the other opposite end of the cross bar 21 is indirectly articulated via a distance bar 22 extending above the opening line 10 and at its upper portion a short distance above the opening line 10, when the bottom doors are in their closed position, in the other side wall 13,14. In this way it always occurs simultaneous an opening and a closing respectively of the bottom doors 4,5 and an eventual tilting danger for the container l is eliminated.
• the fork tubes 6,7 can be designed with a cross section which admits that they are rotatable around the forks of a fork truck during dumping the container 1.
