9 cl, 8 dwg

The invention concerns a container for the transportation and storage of cargoes, including bottom of the container and at least two folding each other side of the wall according to the restrictive part of the clause 1 of the claims.

Foldable containers are well known from the prior art. This kind of foldable containers have at least one bottom of the container with a rectangular contour of the projection on the horizontal plane, with the edges of which is pivotally connected by hinges folding side of the wall, and these hinges with adjustable finger jointed, i.e. with the possibility of rotation, installed in the sockets for pivot pins.

In the folded up position lateral walls happens coupling side walls among themselves, which can again break to, for example, the folding of empty containers for transportation, and it is optional.

Many of foldable containers side walls are made higher than half the width of the bottom of the container, so that when the two opposing side walls of the stack is an " overlapping side walls. Of US 6460717 B1 known container, which lowered the side wall can be operated with the two end positions, namely in the bottom, which lowered the side wall is tight to the bottom of the container, and in the top, where the side wall is offset relative to the lower end position perpendicular to the bottom of the container in parallel up adjacent to the opposite lowered the side wall. From the upper end position the side wall can be installed in a vertical position. In the US 6460717 B1 is also provided socket hinge pin, which takes place in the form of an arcuate oblong holes from the bottom of the container up with the lowered side wall of the hinge pin freely movable slot hinge pin in an oblong hole.

The disadvantage of this collapsible container is that let down the side wall should rise from its lower end position first in the upper stop position, which can then be turn to the side wall in vertical position. If, by mistake, try to install the side wall in vertical position of its lower end position, it can happen when you hold a hinge pin in the hinge pin, which can lead to damage of the container.

In the basis of the invention is to create having a simple design and durable folding mechanism container with folding side walls, which has a possibility especially easy maintenance in comparison with the known mechanisms of folding.

The task in accordance with the invention is solved using the characteristics of the distinctive part of the clause 1 of the claims. Preferred improvement of the invention are different signs of dependent claims.

However, hinge designed in such a way that pivoted up the side wall of the lower end position, i.e. when rotating hinge pin in the hinge pin, articulated finger reported would be sent onward movement to the side wall is shifted in the direction perpendicular from the container's bottom up.

Articulated fingers are installed in vertical position of the side wall are located in the upper area of the grooves in swivel pin and when folded side wall can be placed at the bottom or in the upper pane of the seizure. Due to this, on the one hand, it is possible that when folding the opposite side walls do not require any sequence of folding, because there are two end positions for lowered the side wall. On the other hand, it is ensured that installed in a vertical position the side wall is always in the same position as swivel movement of a finger during installation in vertical position or, respectively, folding up the side wall occurs on a certain path. The clamping of the hinge pin in the lower end position prevented, as it in turn forcibly performs translational motion.

One of the preferred options for the implementation of slot hinge pin is passing on the merits in the longitudinal direction perpendicular to the bottom of the container notch in the form of an oblong hole that was narrowed down, i.e. in the direction of the bottom of the container, and narrowed the scope pivoted up the side wall of the lower end position forms push the paper guide for the hinge pin.

Especially preferably, if the groove is in the narrowed area is limited to an inward trunking tilting-pad or inclined surface. Hatchback Playground can be made in the form of both direct and linear surface, but can also be curved, convex or concave surfaces, which take place from the outer area of the boxes to the inner area of the boxes up and make a side wall of the narrowed area.

Especially preferably, if hatchback Playground performed direct or, accordingly, of the linear and inclined at an angle from + 30 degrees to 70 degrees, preferably from 50 degrees to 60 degrees-especially preferably approximately 53° relative to the surface of the seabed, or, respectively, the bottom of the container. And found out that with these angles are particularly well prevented from holding a hinge pin in the hinge pin.

One of the preferred options for implementation of the hinge pin has a structure that is different from run round in cross-section swivel pin, in particular, cross section, which includes a round or having the shape of a circle segment, the main part of the ledge, which may include preferably rounded the edge of a ledge or flattening, or oviform, if necessary complemented with a flattening, cross section, or may be performed with the cross-section in the shape of an eccentric. Thanks to the structure, differing from circular cross-section, articulated finger particularly well communicated progressive movement.

It was found that, preferably with the lowered side wall tab or, respectively, the main axis of the hinge pin essentially directed downwards, preferably with an inclination of approximately 100 degrees relative to the bottom of the container or, respectively, the main surface of the seabed, in particular, on 10° towards the outer area of the box.

Hinge pin 6 includes round in cross-section the main part 15 and projection 16. Projection 16 when folded side wall 4, as shown in figure 2, is aimed essentially down, i.e. to the bottom of the 2 container, and when folded-up the side wall of 4, as shown in Fig.6, essentially in the direction of the inner area of a container. More precisely, the lug 16 when folded side wall 4 tilted against the bottom 2 container approximately 100 degrees, namely, about 10° in the direction of the external area of the box.

Figure 3-6 describes the process of folding side of the wall 4. When folding lateral wall of 4 she commits swivel movement around resides essentially in the centre of the hinge pin 6 center-17 rotation. Thanks to this, the implementation of joint swivel movement, starting from the lower end position of the side wall 4, causes the translational motion of the center of rotation, the side panel 4 when installed in a vertical position is shifted upwards.

More precisely, pivoted up the side of the wall 4 hatchback Playground 14 outer side wall 11 recess 7 forms push the paper guide for the swivel pin 6 round the main part 15 rolls up on the outer side wall of 11, and projection 16 slides upwards on the inclined platform 14.

Figure 3 shows a lean up approximately 30 degrees side panel 4, which ledge 16 swivel pin 6 adjoins the inclined platform 14, and the round main part 15 swivel pin 6 is adjacent to the outer side wall of 11 recess 7. Figure 4 and 5 show the relevant provisions at 45 degrees or, respectively, 60-degree becomes visible forced guide swivel pin 6.

As shown in figure 4 the folded-up of 45 degrees position of the side wall 4 forced guide projection 16 ends approximately at the inclined platform 14. Side panel 4, as shown in figure 5 and 6, goes on to shoulder 18, and the area of the lower edge of 19 main surface of the lateral wall of 4 attaches to shoulder 18. Rotation of the side wall 4 limited are located on the side wall of 4 resistant element 27, which abuts the regional bar 3, when the side panel 4 is installed in vertical position.

Figure 7 shows a side view of folded-up of the side wall 4 inside the boxes. The lower edge of the 19 side wall of the 4 adjacent to the upper edge of the 20 regional straps 3. Side panel 4 for example, here is joined by two hinges, with this, however, is not a constraint. In addition, it is represented, that articulated fingers 6 are located on both sides continue 21 side of the wall 4 on the bottom. On their ends articulated fingers have 6 tabs 16, which are directed into the inside of the box, i.e. from the plane of the drawing out. Each of the four depicted here projections 16 engages in located on the inner side of the edge trims 3 positioning recess 21, and act as the positioning of elements, which prevent the raising installed in vertical position of the side wall 4 against the bottom 2 container.

On fig.8, 8b, 8c and 8d shown different examples of the implementation of the hinge pin 6. In accordance with the variants of implementation, shown in fig.8, 8b and 8c, hinge pin 6 includes round or having the shape of a circle segment, the main part 15 and the protruding part 16 of the ledge. Projection 16 may be preferable rounded edge of 22 or preferably even flattening 23, wall hanging 24, as shown in the fig.8b and 8c, can be made straight, or may have curves, as shown in the fig.8b and 8c with a reference sign 25.
