Description

The invention relates to a mounting ring for a transport container and to a transport container which is provided for transporting goods.

From the DE 10 2015 105 030 B3 a transport container is known which is designed as a collapsible container. This container consists of a base, a lid and an interposed attachment ring, which is formed, for example, from four side walls. For a return transport of such transport containers after the goods have been delivered, the attachment ring can be folded up and placed on the floor so that the cover subsequently rests on the floor with the attachment ring interposed.

There are also known transport containers in which such attachment rings are designed in two or more parts and are divided into ring sections. In this way, for example, a ring section comprising a front side wall and a side wall section can be removed, with a further ring section comprising at least the rear wall remaining on the floor to protect the goods stored on the floor. Nevertheless, the goods are accessible from the front. The ring sections forming the attachment ring are connected to one another by Velcro fasteners.

The invention is based on the object of proposing a mounting ring for a transport container and a transport container which enables the mounting ring to be constructed in a simple manner and to be easily transferred into a position of use for unloading goods.

This object is achieved by a mounting ring for a transport container, in which the at least two ring sections that form a closed mounting ring have an end edge at the respective end of the ring sections that extends between an upper and lower end face of the ring sections and can be connected to one another by a retaining profile are, the main profile being the opposite end edges of the two adjacent ring sections absorbs and aligns with each other. The retaining profile can be easily plugged onto an end edge of the one ring section and this ring section can be positioned on the floor. The end edge of the further ring section can then also be connected to the retaining profile and placed on the floor. As a result, a closed attachment ring can be created in a simple manner by assembling the at least two ring sections. The same applies to the removal of one ring section from the other ring section. This enables short assembly and dismantling times.

The retaining profile preferably has a first U-shaped receptacle and, opposite this, a second U-shaped receptacle, which are aligned along a common outer leg. As a result, when the respective adjacent end edges of the side sections of the ring section are inserted into the holding profile, an aligned arrangement of the outer sides of the side wall sections with respect to one another can be created. Only a slight protrusion over the outer sides of the side wall sections can also be achieved by the outer leg. As a result, the attachment ring formed by the ring sections can be inserted together with the retaining profile into a groove on the floor and secured therein.

In addition, a latching element, preferably a latching lug, pointing into the U-shaped receptacle is preferably provided, which can be locked with one provided on the end edge of the side wall section of the ring section. As a result, the holding profile can be held on a ring section by a plug-in latching connection. Opposite, the U-shaped receptacle of the retaining profile can only be designed as a plug connection with the front edge of the adjacent ring section.

Furthermore, the at least one side wall section and / or the side wall of the ring section is preferably made of a multi-layer plate, in particular a hollow-chamber plate or three-layer plate, and the front edge compared to the thickness of the side wall section and / or the Sidewall reduced in thickness. As a result, a connection point can be created with the retaining profile which only corresponds to the thickness of the side walls or protrudes only slightly and on one side opposite an inside or outside of the side wall sections or side walls. The ring sections can be formed from so-called hollow-chamber plates or triplex plates, which have a high degree of rigidity. As a result, the load capacity can also be increased when transport containers are stacked on top of one another.

Furthermore, the front edge of the side wall section is preferably formed by heat forming and the front edge is aligned centrally with the thickness of the side wall section or aligned with the outside of the side wall section, so that a wall section of the front edge lies in the extension of a flat section of the side wall. This enables inexpensive production while maintaining a closed side wall, especially when using so-called hollow chamber panels.

Furthermore, the U-shaped receptacle of the retaining profile with the latching element preferably has a width that corresponds to the wall thickness of the front edge. As a result, the holding profile can be received and arranged with an exact fit on the one ring section.

Furthermore, the U-shaped receptacle, which is opposite the receptacle with the latching element, preferably has a width that is greater than the wall thickness of the front edges. This enables the front edges to be easily threaded or inserted into the hollow profile. The width of this U-shaped receptacle preferably corresponds to twice the thickness of the wall thickness of the front edge.

Furthermore, the width of the U-shaped receptacles of the retaining profile is preferably narrower than the thickness of the side wall sections. As a result, an inner volume of the transport container can be formed exclusively by the inner surfaces of the ring sections, and the holding profile does not protrude into the interior with respect to these inner surfaces.

Furthermore, the respective inner legs of the U-shaped receptacle of the retaining profile preferably have a length that corresponds to the width of the Wall section of the end edge, which is reduced in thickness compared to the side wall sections, corresponds to or is made shorter. As a result, with the same length of the inner leg and the width of the wall section of the front edge, additional support of the side wall section on the inner legs of the U-shaped receptacle can take place.

Advantageously, the one ring section of the attachment ring is designed as a so-called U-ring, which comprises a rear wall and a side wall section adjoining it laterally, which are preferably integrally connected to the rear wall by hinges. Such a U-ring can be folded up in a simple manner. This can also be set up on a floor, in particular in a groove in the floor.

Furthermore, the at least one further ring section is designed as a so-called C-ring, which has a front side wall and a side wall section adjoining it laterally, which are preferably integrally connected to the front side wall by a hinge. The C-ring differs from the U-ring in that the side wall sections of the C-ring are preferably made shorter than those of the U-ring. For example, the width of the side wall sections of the C-ring is one third of the length of a side wall and the side wall sections of the U-ring are two thirds of the corresponding side wall. The position of the two side wall sections is preferably identical. As a result, in the case of a mounting ring made of two ring sections, the connection points are in one plane, and the ring sections can be sprayed onto the floor without a specific orientation.

A latching element, in particular a recess, is preferably provided on the respective end edge of the U-ring, so that the retaining profile is held with the U-shaped receptacle which the latching element has by means of a plug / latching connection. The respective front edges of the C-ring are preferably designed free of latching elements. These only form a plug connection with the U-shaped receptacle of the retaining profile. As a result, the retaining profile can remain on the U-ring when the attachment ring is built up or dismantled. This has a simplified handling. Thus, on the one hand, the C-ring can be removed in a simple manner, with the U-ring remaining on the floor in order to protect the goods or goods that are still stored on the floor of the transport container for subsequent removal. On the other hand, simple handling can thereby be made possible in order to separate ring sections from one another in order to then fold them together for return transport.

The object on which the invention is based is further achieved by a retaining profile for a mounting ring, which comprises at least two ring sections, which includes the features relating to the retaining profile according to one or more of the above embodiments.

The object on which the invention is based is further achieved by a transport container with a base and a lid and a mounting ring arranged in between and consisting of at least two ring sections, the mounting ring being designed according to one of the embodiments described above. Advantageously, the floor and /
or the cover is also made of plastic.

• Figure 4 a schematic sectional view along the line IV-IV in Figure 1 .

In Figure 1 FIG. 11 is a perspective view of a shipping container 11 shown. This transport container 11 consists of a base 12, an attachment ring 14, which comprises several side walls 15, and a cover 16 that can be placed on the attachment ring 14. A circumferential groove or recess 17 is preferably provided on the base 12 along the outer edge area, which is intended for receiving and positioning of the attachment ring 14 is used. A circumferential recess is provided on an underside of the cover 16 so that the cover 16 rests securely on the attachment ring 14.

The attachment ring 14 comprises ring sections 18, 19. In the exemplary embodiment, the attachment ring 14 consists of two ring sections 18, 19. A connection point 22 is formed between the two ring sections 18, 19. The ring sections 18, 19 are each connected to one another in the connection point 22 by a retaining profile 21. Alternatively, the attachment ring 14 can also be constructed from several ring sections 18, 19.

To transfer the transport container 11 for a return transport, the cover 16 is first lifted off, the ring sections 18, 19 separated from one another and folded together. These folded-up ring sections 18, 19 are then placed on the floor 12. The cover 16 is then positioned thereon. This enables a small transport volume for the return transport, as shown in Figure 2 is shown.

The attachment ring 14 comprises the first and second ring sections 18, 19. The connection point 22 is provided, for example, in a left and right side wall 23, 24. Alternatively or in addition, a connection point 22 can also be in a rear wall 25 or a front side wall 26.

According to the exemplary embodiment, the first ring section 18 comprises the rear wall 25 as well as right and left side wall sections 27, 28. These side wall sections 27, 28 are preferably connected in one piece to the rear wall 25 by a hinge 29. The hinge 29 can be introduced by stamping or hot forming.

The ring section 19 comprises the front side wall 26 as well as right and left side wall sections 31, 32 arranged laterally thereon, which are preferably connected in one piece to the front side wall 26 with a hinge 29. The size of the right side wall sections 27, 31 and the left side wall sections 28, 32 correspond to the side walls 23, 24 with the interposition of the retaining profile 21 at the connection point 22.

The right and left side wall sections 27, 28 of the first ring section 18 are wider than the right and left side wall sections 31, 32 of the front ring section 19. The ring sections 18, 19 have a common upper end face 33 and a lower end face 34. The lower end face 34 of the attachment ring 14 rests in the recess 17 in the base 12. The cover 16 rests with its recess on the upper end face 33 of the attachment ring 14.

In Figure 3 is a schematic sectional view along the ring portion 18 shown in an unfolded position. This ring section 18 comprises the rear wall 25 and the two right and left side wall sections 27, 28 each connected to it by the hinge 29, one of the two hinges 29 not being shown. The side wall 15 and the side wall sections 23, 24 consist, for example, of two outer plastic layers 47, 48, between which a third plastic layer 49 is formed. This can be a knobbed film or the like, which has raised areas or depressions formed on one or both sides. These plastic layers 47, 48, 49 are welded to one another. The embossed sections 18 have an end edge 37 at each end. This end edge 37 extends between the upper and lower end faces 33, 34 of the ring sections 18, 19. This end edge 37 is tapered in wall thickness compared to the side wall 15 and the side wall sections 27, 28. The front edge 37 can be produced by heat forming in that the outer plastic layers 47, 48 are pressed together. This creates a wall section 58 which is rigid and closes the side walls 15 or side wall sections 26, 27. The wall thickness of the Wall section 58 is determined by the thickness of the plastic layers 47, 48, 49 and the pressing force. Preferably, an outer side of the end edge 37 is aligned flush with the outer side 57 of the side wall 15 or the side wall sections 27, 28. A latching element 55 is provided on the end edge 37. This latching element 55 is designed, for example, as a recess. The latching element 55 is provided opposite the outside 57 on the wall section 58. Such a latching element 55 can take place at the same time as the end edge 37 is produced. The latching element 55 is adapted to the shape and / or contour of a further latching element 66 in the retaining profile 21.

The side wall 15 and the right and left side wall sections 27, 28 are connected by the hinge 29. This can in turn be produced by heat forming, which makes it possible for the side wall sections 26, 27 to be pivotable or collapsible relative to the side wall 15.

The ring section 18 has the latching element 55 at the respective end of the right and left side wall sections 27, 28, which, after being set up on the floor 12, preferably faces the inside.

The structure of the ring section 19 preferably corresponds to that of the ring section 18. The ring section 19 differs from the ring section 18 in that no latching element 55 is introduced at the end edge 37. Furthermore, the ring section 19 can differ from the ring section 18 in that the right and left side wall sections 31, 32 are designed to be narrower than the side wall sections 27, 28 of the ring section 18.

In Figure 4 FIG. 4 is a schematic sectional view taken along line IV-IV in FIG Figure 1 shown. This sectional view shows the connection point 22 with the holding profile 21 and the two ring sections 18, 19 arranged adjacent to one another. The right side wall section 27 of the ring section 18 is connected to the right side wall section 31 of the ring section 19 by the holding profile 21. A closed side wall 15 is thereby formed.

The holding profile 21 has two opposing U-shaped Recordings 61, 62 on. These two U-shaped receptacles 61, 62 extend along a common outer leg 63. The two U-shaped receptacles 61, 62 are separated from one another by a common web 64. This web 64 each forms a base for the U-shaped receptacles 61, 62, which are aligned opposite to one another. The receptacle 61 comprises a latching element 66 which points toward the inside of the receptacle 61 and which is designed, for example, as a projection. This latching element 66 forms a plug-in / latching connection with the latching element 55 on the end edge 37. The width of the U-shaped receptacle 61 is preferably adapted to the wall thickness of the wall section of the end edge 37. An inner leg 68 of the U-shaped receptacle 61 has a length which preferably corresponds to the width of the wall section 58. As a result, an outwardly directed end face 69 of the inner leg 68 can be set back with respect to an inner wall surface of the side wall section 27 and / or the side wall 15. In addition, the end face 69 can be supported in the transition area between the end edge 37 and the non-tapered flat section 56 of the side wall 15.

The outer leg 63 is longer than the inner leg 68 in the area of the U-shaped receptacle 61.

The second U-shaped receptacle 62 is made wider than the first U-shaped receptacle 61. The second U-shaped receptacle 62 preferably has twice the width of the first U-shaped receptacle 61. The inner leg 68 of the second U-shaped receptacle 62 preferably runs flush with the inside of the flat section 56 of the side wall section 31 or is set back in relation to it. An end face 69 of the inner leg 68 of the second U-shaped receptacle 62 can also be supported in the transition area between the end edge 37 and the flat section 56 of the right side wall section 31. The outer leg 63 is longer than the inner leg 68 in the second U-shaped receptacle 62.

This arrangement allows that between the retaining profile 21 and the Ring section 18 a plug / latching connection is created so that the retaining profile 21 remains on the ring section 18 during normal use. The ring section 19 can be connected to the retaining profile 21 by a plug connection. To facilitate the formation of this plug-in connection, the U-shaped receiving section 62 is therefore made wider than the end edge 37 of the right side wall section 31.

The above statements apply analogously to the retaining profile 21, which connects a left side wall section 28 of the ring section 18 to a left side wall section 32 of the ring section 19. It is decisive that a plug / latching connection is formed between the retaining profile 21 and one of the ring sections 18 and only one plug connection is formed with the opposite ring section 19.

The retaining profile 21 extends completely along the end edge 37 of the first and second ring sections 18, 19.

The retaining profile 21 is preferably designed as a extruded / pressed profile or an extrusion profile made of plastic.
