Description

Articulation between two relatively rotatable wall parts of a transport container

The invention relates to an articulation according to the preamble of claim 1 between two relatively rotatable wall parts, in particular of a box-shaped transport container.

In a known container as described in DE 9308051.4U, the top wall and the side wall are hinged on the bottom by means of a pivot bearing structure and it is fixed in the assembled position by a releasable lock to form the container. After the locking element has been released, the side walls and/or the top wall are swiveled outwards into a position flush with the bottom by means of the swivel bearing. Thus, the container has a small transport volume when it is empty. In this case, it is disadvantageous that the containers in this state occupy a large base area and thus take up undue space on the transport pallet for recycling the empty containers. In another known collapsible transport box as described in EP 0443327A2, the side walls can be connected to the bottom via hinges in such a way that the side walls in the stacked state can be pivoted inwards parallel to the bottom. In this case, the cost-intensive hinged connection of the side walls to the base and the unstable support of the side walls, thereby reducing the fill volume of such transport containers, is disadvantageous.

The object of the present invention is to devise a hinged structure of a transport container which can withstand high loads and which can selectively pivot the longitudinal and/or transverse side walls into a position flush with or parallel to the bottom.

This task is achieved by the technical features of claim 1 . Since the two hinges of an articulated body each have at least one degree of freedom, in addition to the flush position, it is also unexpectedly and advantageously possible for the wall to be selectively turned relative to each other into a parallel position, where the wall and the The inner surface or its outer surface, in particular the outer surface, is superimposed on one another.

An embodiment as claimed in claim 2 is also advantageous, as a result of which a simple replacement of the wall and/or the hinged body and also an easy assembly of a transport container designed in this way is possible.

The refinement as claimed in claim 3 is also possible, since this reduces the number of parts required for the transport container.

According to a preferred development as claimed in claim 4 , a highly loaded hinge structure is obtained.

The configurations as claimed in claims 5 and 6 are also advantageous, whereby a variable adjustment of the configuration of the parts of the transport container is achieved.

According to a preferred development according to claim 7, a centering effect in the hinged structure is achieved.

The development as claimed in claim 8 allows a disengagement movement in order to release the hinged structure.

According to the preferred developments according to claims 9-12, a preselected rotatability between the wall parts or between the wall parts and the articulation body can be achieved.

An embodiment according to claim 13 is also possible, wherein unintentional disengagement of the side wall parts from each other or from the articulation body is prevented.

Claims 14 and 15 describe preferred developments in which a securing structure against axial movement is obtained irrespective of the disengagement behavior of the hinged structure.

The development as claimed in claim 16 is also advantageous in that a locking device is obtained which prevents the wall from turning in a specific position.

Finally, the refinement as claimed in claim 17 is also advantageous, since in this way it is effectively avoided that excessive forces are exerted on the joint.

In order to better understand the present invention, the present invention will be further described in conjunction with the embodiments shown in the accompanying drawings. in:

FIG. 6 is a cross-sectional view of the hinge structure according to line VI-VI of FIG. 5 .

FIG. 1 shows a container 1 , in particular a box-type transport container 2 . This container is formed by a bottom 3, two opposite longitudinal side walls 4 and two opposite transverse side walls 5 perpendicular to the longitudinal side walls and forming relatively rotatable wall portions 6 . The longitudinal side walls 4 and the transverse side walls 5 are formed by wall parts 7 having inner surfaces 8 facing each other. In the assembled state in which the longitudinal side walls 4 or the transverse side walls 5 are perpendicular to the bottom 3 , the inner surface 8 forms an interior space 9 for accommodating various transport items.

An outer surface 10 delimiting the wall 7 opposite the inner chamber 9 is parallel to the inner surface 8 . The wall part 7 is also surrounded by a web 11 integral with the wall part, which protrudes from the inner surface 8 opposite the inner space 9 by a web width 12 measured parallel to the base 3 . The edge 11 is delimited by an edge outer surface 13 facing away from the inner surface 8 . In the plane of the strip outer surface 13 whose distance from the inner surface 8 is equal to the strip width 12, the outer shell surface 14 is parallel to the inner surface 8 and surrounds the transverse side wall 5 or the longitudinal side wall on the outside opposite the inner space 9 4. A webbing 15 and preferably a reinforcement is formed integrally on the outer surface 10 of the wall part 7 , wherein the wall part 7 has recesses 16 in order to reduce the transport weight of the transport container 2 . The recess 16 is designed in this case as a handle opening 17 , which is delimited by a handle edge 18 formed on the wall part 7 and protruding vertically opposite the interior 9 .

The end faces 19 delimiting the longitudinal side walls 4 and/or the transverse side walls 5 are perpendicular to the inner surface 8 or outer surface 10 and perpendicular to the bottom 3 . A centering and/or locking element 20 is provided on this end face, in particular integrally formed. A centering and/or locking notch 21 located in an imaginary footprint 22 is associated with the centering and/or locking element 20 . The covering area 22 is a section of the inner surface 8 of the wall part 7 which is perpendicular to the wall part 7 with the centering and/or locking means 20 . The cover area 22 thus has a cover width 23 approximately equal to the strip width 12 and is measured from an end side 24 perpendicular to the lateral side walls 5 and/or longitudinal side walls 4 of the base 3 towards the interior 9 of. The strip edge 11 preferably has a centering notch 26 on the longitudinal side 25 perpendicular to the end face 19 or the end side 24 and parallel to the bottom 3, the longitudinal side 25 is parallel to the bottom 3 and defines the border of the strip edge 11, and the centering recess The opening 26 prevents relative movement of these transport containers during transport, especially in the case of a plurality of transport containers 2 stacked on top of each other.

Of course, the centering and/or locking element 20 can also be installed in the cover area 22, which is thus preferably formed in one piece with the wall part 7 and which is opposite to the housing face 14 in the direction of the end face 19 such as the longitudinal side wall 4. The direction protrudes from the inner surface 8 . In this variant, centering and/or locking notches 21 can be provided on the end face 19 .

The base 3 is formed by a planar base 27 which may likewise have a number of recesses 16 for reasons of weight. The outer surface of the base plate 27 is surrounded by a bottom bar edge 28 whose upper side 29 is parallel to the base plate 27, and the upper side 29 also forms a shoulder height 30 measured perpendicular to the base plate 27 than the base plate 27. inner surface8. The outside of the base strip 28 is delimited by an annular side 31 facing away from the interior 9 . The bottom 3 also has a web 15 , not shown, aligned opposite the cavity 9 , which is bounded in the opposite direction to the cavity 9 by the shell face 14 parallel to and facing away from the upper side 29 .

For example, the two wall portions 6 will be defined as the first wall portion 32 and the second wall portion 33 below.

The first wall portion 32 such as the lateral side wall 5 and the second wall portion 33 such as the bottom 3 can relatively rotate around at least one rotating shaft 34 . The axis of rotation 34 is parallel to the bottom 3 and the inner surface 8 . In this embodiment, the axis of rotation 34 can not only be in the longitudinal side wall 4 , it can also be in the transverse side wall 5 . However, it is also possible, for example, to connect the transverse side walls 5 rigidly to the bottom 3 and only the longitudinal side walls 4 rotate about the axis of rotation 34 oppositely and relative to the bottom 3 .

Between the walls 6 of the two transport containers 2 which rotate relative to each other about at least one axis of rotation 34, there is a hinged structure 35 which has at least one joint, such as formed by a swivel pin 36 and a swivel pin seat 37 or by a film hinge. And it has a hinge 38 with at least one degree of freedom. In this case, the axis of rotation 34 is parallel to a side 39 of the wall 6 , which is formed, for example, by the longitudinal side 25 and the edge outer surface 13 . Thus, the first wall portion 32 can be adjusted relative to the second wall portion 33 to a vertical position that is flush or aligned with the second wall portion 33 or vice versa. The hinge structure 35 has two hinges 38 each having at least one degree of freedom, which are arranged at a distance from each other via a joint body 40 , and the axes of rotation 34 of the two hinges 38 are arranged parallel to each other. In this way, the first wall part 32 can be brought into a position against the inner surface 8 and/or the outer shell surface 14 of the second wall part 33 .

At a position close to and/or perpendicular to the second wall portion 33 , the first wall portion 32 and/or the hinge body 40 are arranged to extend from the inner surface 8 along the direction of the outer shell surface 14 of the second wall portion 33 Inside the side 31 of. The pivot axis 34 of the hinge 38 is arranged between the inner surface 8 and the outer surface 14 of the wall 6 , ie between the base 3 of the longitudinal side wall 4 and the transverse side wall 5 . The rotating shaft 34 passes through the centers of the rotary pin 36 and the rotary pin seat 37 .

The joints 38 separated from one another by the joint body 40 or their parallelly arranged rotational axes 34 are spaced from one another by an axial distance 41 measured perpendicular to the base 3 .

In this way, the first wall portion 32 is turned from a position perpendicular to the bottom 3 to a position parallel to it by a total of 270 degrees of rotation. If the wall height 42 of a wall portion 6 measured perpendicularly to the bottom 3, such as the longitudinal side wall 4, is not greater than half the inner width 43 that separates two inner surfaces 8 facing each other and/or as two With the inner sides 44 of the bottom strip edges 28 facing each other, the wall part 6 , ie the two longitudinal side walls 4 , can be turned in the direction of the inner chamber 9 into a position parallel to the bottom 3 and flush with each other. The lateral sidewall 5 can also rotate relative to the bottom 3 via the rotating shaft 34 . In this case, the hinged body 40 can be moved from a position perpendicular to the bottom 3 and facing the inner chamber 9 by 180° into a position perpendicular to the bottom 3 and facing away from the inner chamber 9 . Thereby, wall portion 6 namely lateral side wall 5 can turn 90 degree angles relative to hinge body 40 from a position perpendicular to bottom 3 and protruding from the bottom in the direction opposite to inner chamber 10 into a position parallel to bottom 3. Location.

The transport container 2 can be configured in the empty transport state or in the returned transport state in such a way that the longitudinal side walls 4 are folded in the direction of the bottom 3, that is, against the inner surface 8 or upper side 29, and the transverse side walls 5 are turned outwards and It rests against the web 15 running opposite the inner surface 8 or the upper side 29 or against the outer shell surface 14 delimiting the interior space 9 opposite to it.

FIG. 2 shows an end view of the container 1 or transport container 2 . The longitudinal side walls 4 have a length 45 , measured parallel to the base 3 , which separates the end faces 19 from one another. The base 3 has a base length 46 which is greater than the length 45 and which separates the sides 31 . A bottom side 47 parallel to the longitudinal side 25 of the wall part 6 , eg facing away from the longitudinal side wall 4 , is spaced from the upper side 29 of the bottom strip 28 by a dimension greater than a wall height 48 of the articulation body 40 measured parallel thereto. A number of articulation structures 35 are provided, for example, in a section of length 45 which also delimits articulation body 40 . The swivel pin 36 is connected to the wall 6 and to the web 11 of the articulation body 40 by means of webs 49 . The web 49 has a web length 50 , measured parallel to the inner length 44 , which protrudes from a pin shoulder 51 of the pivot pin 36 by a shoulder length 52 in both directions.

For example, the web 49 of the hinge structure 35 is integrally formed on the side 11 of the wall 6 . The webs 49 of the hinge structure 35 arranged between the base 3 and the hinge body 40 are formed (in one piece) on the strip edge 11 of the hinge body 40 . The limb 11 of the articulation body 40 preferably has, on the side facing the wall 6 , two centering elements 53 spaced apart from one another in the direction of the inner side 44 . The centering element 53 should prevent relative movement when the folded transport containers 2 are stacked and preferably prevent such movement during transport of the transport container 2 . For example, two openings 54 spaced from each other along the length 45 are located on the side facing the sides 11 of the hinged body 40 of the bottom 3, and the openings 54 are smaller in the direction of the wall 6 than the sides of the hinged body 40 facing the bottom 3. The bottom side 55 of 11 protrudes by an opening depth 56 .

Formed at the opening 54 is a pin 57 and a stop 60 , which protrude over a section on the bottom side 58 of the bottom side 28 facing away from the top side 29 of the bottom side 28 and in the direction opposite to the hinge body 40 . The pin height 59 measured perpendicularly to the base 3 acts like a base 61 of the opening 54 which is spaced from the bottom side 55 of the bottom strip edge 28 by the opening depth 56 . In the case of a preferred 180° rotation of the articulated body 40, the stop device 60 touches a stop surface 62 which is spaced from the bottom side 58 by the pin height 59 and it prevents the articulated body 40 from further turning 180°.

FIG. 3 shows a section of a transport container 2 in section, in which the centering element 53 is shown more clearly. It is formed by a support member 63 preferably integrally formed on the longitudinal side 25 of the hinge body 40 sides 11, the support member 63 has a supporting web 64 protruding from the longitudinal side 25 opposite to the bottom 3 and A bottom web 65 perpendicular thereto and parallel to the longitudinal side 25 . On the surface of the base web 65 facing away from the base 3 is preferably integrally formed a centering pin 66 which is approximately semicircular in an end region 67 facing away from the base 3 . The bottom web 65 is also connected to the side 11 by a web 68 perpendicular to the supporting web 64 .

As can also be seen from this figure, the bottom strip edge 28 is approximately semicircular in an end region facing away from the interior space 9 . The bottom 3 also has one or more bottom webs 70 forming the webs 15 on the bottom side 69 of the bottom 27 facing away from the top side 29 of the bottom side 28 , which is supported against the interior 9 with a web height 71 69 on the underside of the bottom. On the bottom web 70 forming the side opposite to the bottom web 15 of the bottom plate 27, a shell surface 14 mounted parallel to the bottom plate 27 is arranged, which delimits the web 15 or bottom web 70 in the direction opposite to the inner chamber 9. borders and thus defines the bottom 3 .

Another detail of the transport container 2 is shown in detail in FIG. 4 , wherein in particular the hinge structure 35 between the wall 6 and the hinge body 40 or between it and the bottom 3 is shown. The swivel pin 36 has a diameter 72 and it is connected to the web 11 via webs 49 as shown. The web 49 has an inner surface 73 perpendicular to the strip edge 11 and facing the inner chamber 9 and an inclined surface 74 inclined relative to the strip edge 11 and facing away from the inner chamber 9 .

The hinge structure 35 arranged between the wall 6 and the hinge body 40 and in particular its swivel pin 36 has, as shown, an axis of rotation 34 passing through its center, which is spaced from the 6 sides 11 of the wall in the direction of the bottom 3 Distance 75. This distance is selected such that it is slightly greater than the distance 76 which is the distance from the axis of rotation 34 away from the bottom 3 to the longitudinal sides 25 of the 40 sides 11 of the articulation body. The longitudinal side 25 has a circular arc-shaped curve with a circular arc surface 77 in a region facing the interior 9 . It projects in the direction of the interior 9 from a cam 78 which has a cam outer surface 79 at a cam distance 80 from the rotational axis 34 .

The cam spacing is substantially equal to the distance 75 and greater than the spacing 76 , thereby preventing the wall 6 from automatically rotating in the direction of the bottom 3 . Such a rotation is only possible by elastically deforming the cam 78 such that the cam distance 80 is equal to the distance 75 , which can be achieved by an additional force on the wall 6 in the direction of the cavity 9 . The swivel pin 36 is located in a swivel pin seat 37 , which forms, for example, a bearing bush for the swivel pin 36 .

In case the hinge structure 35 is arranged between the base 3 and the hinge body 40 , its function is similar to that of the hinge structure 35 already described. In this case, the axis of rotation 34 of the articulation structure 35 is likewise at a distance 75 from the bottom side 55 of the sides 11 of the articulation body 40 which faces away from the longitudinal side 25 . This distance is greater than the distance 76 , which is the distance measured from the axis of rotation 34 to the upper side 29 . Thus, a 180° rotation of the hinged body 40 is ensured, wherein the bottom side 55 faces the bottom side 58 of the bottom strip leg 28 in the rotated position. The swivel pin 36 is likewise located in a bearing sleeve arranged in the bottom strip edge 28 , but this bearing sleeve only completely delimits the swivel pin 36 in the region of the pin shoulder 51 shown in FIG. 2 .

A hinge structure 35 between the wall parts 32 , 33 , such as between the wall part 6 and the bottom 3 , is shown in FIGS. 5 , 6 . In this figure, the wall portion 6 is shown with a solid line at its planar position flush with the bottom 3 and with a broken line at its position at a 90° angle with respect to the bottom 3 . The base 3 has a groove 81 running parallel to the annular side 31 through an outer surface 10 facing away from the inner surface 8 . The groove bottom 82 facing the inner surface 8 is semicircular, wherein the depth 83 of the groove 81 is greater than the width 84 . A longitudinal center axis 85 parallel to the side surface 31 and the inner surface 8 forms the axis of rotation 34 of the articulation 35 , which at the same time lies approximately in the vicinity of the thickness 86 of the bottom 3 . The side 31 is rounded in a direction extending transversely to its longitudinal extension, with a radius starting from the longitudinal center axis 85 equal to the distance 88 between the inner surface 8 of the base 3 and the longitudinal center axis 85 . Concentric with the longitudinal center axis 85, in the groove 81 extending in the direction of the longitudinal center axis 85, a swivel pin 36 is provided, which is connected to the wall 6 or a strip edge 90 delimiting the wall 6 in the direction of the bottom 3 via a web 49. , the side 89 facing the bottom 3 is flexibly connected. In this case, the distance 91 between the side surface 89 and the longitudinal center axis 85 is approximately equal to the radius 87 of the rounded side surface 31 . In the region of the hinge body 40 , a leg 92 of a receiving groove 81 has a recess 93 for receiving the hinge body 40 except for half the thickness of the hinge body 40 in the direction assigned to the region of the bottom 3 of the interior space 9 , the notch also protrudes from the side 31 by a distance 91 . In the direction of its longitudinal extension, the pivot pin 36 has a length 94 approximately equal to twice the width 95 of the web 49 . In this way, end regions 96 , 97 of the swivel pin 36 protruding from the hinge body 40 are formed, by means of which end regions the wall part 6 is held rotatably in the groove 81 . In this case, the groove 81 is closed in one of the end regions 96, 97 (as shown in the end region 96) in the direction of the outer surface 10 by a clamping shoulder 98, thereby forming a Receptacle 99 of end region 96 of swivel pin 36 .

An end face 100 of the swivel pin 36 arranged opposite the receiving chamber 99 is provided with a locking element 101 which delimits the groove 81 in a direction extending longitudinally along the groove 81, which is formed on the base 3 and which extends from the inner surface 8 to the longitudinal direction. In the region of the central axis 85 and facing the end face 100 , a stop surface 102 is formed which prevents the axial movement of the pivot pin 36 . Opposite the base 3 , in a weakened region formed by the slot 103 , the locking element 101 is elastically deformable in the vertical direction as indicated by the double arrow 104 . In connection with the conical shoulder 105 , a plug-fitting of the joint structure 35 by inserting the swivel pin 36 into the groove 81 and the receiving space 99 is achieved. Since the locking member 101 is turned away from the locked position of the swivel pin 36 in the direction of the inner surface 8 , the swivel pin 36 can move axially in the direction of the arrow 106 into the disengaged position of the wall portion 6 . In this position, the webs 49 lie outside the end faces 107 of the cutouts 108 of the bottom 3, which are centered on both sides of their longitudinal extension. In this way, the wall portion 6 can be separated from the bottom portion 3 .

According to a preferred embodiment, the transport container according to the invention is in particular made of plastic, but other embodiments such as wood, metal or the like can be used here.

In order to better understand the present invention, the main parts of the present invention are drawn partly not to scale in the various drawings.

Finally, it should be pointed out that the combinations described in the above embodiments, especially the solutions indicated in the dependent claims can be combined freely, and each technical feature can form an independent design solution of the present invention.
