Description

Stackable system container and transport system

The invention relates to a stackable system container according to the preamble of claim 1, a further container according to the preamble of claim 8 and a transport system according to the preamble of claim 15.

From DE 10 2013 110 496 a stackable system container with an upwardly open storage space having bottom part and a pivotally mounted on the bottom part and the storage space upwardly bounding lid part is known. In addition, the system container two on opposite side walls of the bottom part movably mounted coupling devices which serve to couple the system container with other Systembehältem and thus allow a secure stacking of such system containers. The coupling devices are designed to be movable between a rest position in which the coupling device is out of engagement with the further system container and a coupling position in which the coupling devices can be brought into engagement with the further system container, and with corresponding upwards over an upper side cooperating holding the projecting coupling element of the system container or the lid part of a similar container arranged underneath. The coupling elements are an integral part of the corresponding bottom part and each comprise at least one latch for engaging the coupling device. The coupling elements are also arranged at opposite ends of the top of the system container and allow the centering, positioning and stacking of several such system container each other. After aligning several Systembehältem these can be dimensionally stable, but releasably connected via the coupling devices and the coupling elements. In order to achieve a simple and fast connection of the system container, the coupling devices are biased, for example via a spring element in each case in a coupling position, so that the coupling devices automatically connect to the coupling elements of the other system container, as soon as they are assembled with sufficient pressure. This form and frictional connection allows comfortable carrying several interconnected system container in one hand. Furthermore, from the prior art, a distribution box from the house Peddinghaus is known, the cover has outer guide rails for introducing further, smaller boxes, the smaller boxes are pushed by clamping into corresponding guide grooves on the lid.

The US 2009/0236255 Al shows a stackable system container having a bottom part and a fastened to this lid part, wherein the two parts are connected to one another via fastened to the bottom part wings and these wings are attached via film hinge on the bottom part.

DE 7244356 has a container for storing and transporting goods needed in hospitals to the object, wherein a plurality of similar containers with locking devices are connected to each other. WO 2017/001083 shows a stackable storage container with a body and a lid, wherein side walls of the body are provided with latching arms, wherein the body has feet and wherein the lid has latching cams on the upper side.

From Hitachi also accessory boxes for storage and transport of small parts are known, the lid of a box has a plurality of guide rails, in which more overlying boxes can be inserted. The guide rails each have a catwalk, which is under the other, arranged on the container further inserted during insertion. The catwalks point away from each other, so each catwalk points to an opposite outside of the box. This requires a very precise placement of the two boxes on each other to allow a secure locking. In addition, the projecting towards the outside of the box walkways are not visible when placing the container to be arranged above, whereby the placement and insertion of the overlying box is difficult. The object of the invention is to provide a stackable system container and a transport system, which allows a particularly stable and intuitive mutual attachment of a container on a system container. This object is achieved, which relates to the stackable system container, with the characterizing features of claim 1, which relates to the second container arranged above, by the characterizing Features of claim 8 and in terms of the transport system by the characterizing features of claim 15. Advantageous embodiments of the invention can be taken from the respective subclaims.

The stackable system container according to the invention is characterized in that the cover part has two guide rails spaced apart from one another on an upper side. The guide rails, which are preferably aligned parallel to each other, allow a positive reception of another system container. To connect the system container, the upper system container is inserted into the guide rails of the lower system container, resulting in a particularly stable form-fitting composite. The guide rails can each be formed on the edge of the cover part adjacent to two opposite side walls of the cover part or also spaced therefrom.

The guide rails each have a Faufsteg, wherein the Faufstege project toward each other. The Faufstege can be taken under another from a container. By this rear grip a particularly stable mutual attachment is possible.

In order to accelerate the insertion of a container into the guide rails of the system container, the Faufstege each having a recess, so that the insertion process does not have to be done over the entire catches of the guide rails, but can be done only over a part and thus much faster.

In a preferred embodiment, stacked system containers can be provided for mutual locking, that at least one upwardly projecting Arretiemase is provided on the cover part. The Arretiemase, which may be arranged between the guide rails or integrally incorporated in one of the guide rails, forms a stop in the retracted locking position, so that the connected system container not readily solve.

It can also be provided that at least one further guide rail is arranged on the cover part between the two guide rails, so that a plurality of smaller system containers can be fixed side by side on the cover part. The middle guide rail can for this purpose have two Faufstege, one of which projects in the direction of the lateral guide rails. In a manufacturing technology favorable embodiment, the guide rails can be formed integrally with the cover part, but it is also possible to form the guide rails separately, so that they can be retrofitted or modified.

In a particularly advantageous embodiment, two rails may be arranged on the bottom part, which are in particular designed to be complementary to the guide rails on the cover part. As a result, a plurality of such system containers can be stacked on one another in a particularly simple manner and detachably connected to one another.

In a structurally favorable embodiment, the rails can be formed by the bottom plate edges of the bottom part, which project laterally from opposite side walls of the bottom part.

In order to accelerate the insertion of the further container in the guide rails, the rails can each have a recess corresponding to the catwalks. The recesses preferably extend over a distance which is greater than the elongated extension of the sections of the catwalks delimited by the recesses.

In order to ensure a stable mutual locking of the system container with the container, at least one of the rails may have a locking stop corresponding to Arretiemase on the cover part. Due to the positive engagement between locking stop and Arretiemase a particularly stable locking in the retracted position is possible.

In an advantageous embodiment, the distance between the upper edge of the running rail and the lower edge of the Arretieranschlags be greater than the height of Arretiemase. In order for the Dearretieren in the retracted position, the upper system container can be raised in a front portion and thus tilted about an axis transverse to the pull-out, so that the locking stop can be raised and moved over the Arretiemase. In a structurally favorable embodiment, the locking stops can be formed in a side recess of the corresponding side wall of the bottom part. As a result, the locking stops are protected from external influences and hidden visually appealing.

In addition, a transport system with a system container and a further container is claimed, wherein the system container arranged on a cover part guide rails, each having a catwalk, which can be engaged behind by complementary rails of the container to be arranged above holding.

In an advantageous embodiment, the transport system may comprise a locking device with at least one Arretiemase and a corresponding locking stop for locking the second system container in an inserted rear locking position.

Preferably, in each case an arresting lug can be arranged on the guide rails for guiding the second system container in the pull-out direction. As a result, a mutual tilting of the container and the system container is avoided.

Other features and advantages of the invention will become apparent from the following

Fig. 3 is a perspective view of another transport system with two spaced apart alternative containers or system containers;

4 is a perspective view of an alternative embodiment of a

System container with additional central catwalk; FIG. 1 shows a perspective view of a transport system 1, comprising an upper container 2 and a lower system container 3 detachably connected thereto. The upper container 2 comprises a bottom part 4 and a lid part 5 pivotably connected thereto, by means of which a storage space of the container 2 is delimited. The cover part 5 can be fixed by means of closure tabs 6 relative to the bottom part 4 in the closed position shown in order to prevent unintentional opening of the upper container 2. At the front, the upper container 2 also has a carrying handle 7, which is pivotally attached to the bottom part 4. Similarly, the (lower) system container 3 is formed, which comprises a bottom part 8 and a lid member 9 pivotally connected thereto, which by means of

Locking tabs 10 are mutually fixable in the closed position shown. In addition, a carrying handle 11 is pivotally attached to the front of the bottom part 8 of the lower system container 3. The upper container 2 has pivotally arranged coupling devices 12 on opposite side walls of the bottom part 4 and coupling elements 13 corresponding thereto on the upper side of the cover part 5. By such a configuration of the upper container 2, a plurality of identical containers can be stacked on one another and be detachably connected by means of the coupling device and the coupling elements. For the design of the coupling device, reference is made to the disclosure of DE 10 2013 110 496 and DE 10 2016 112 853, the content of which is incorporated into this application.

The lower system container 3 also has corresponding coupling devices and coupling elements for stacking and securely connecting multiple system containers.

Both the upper container 2 and the lower system container 3 are mirror-inverted, so that the corresponding elements of the containers 2, 3 are identical on the left and right sides, as can be seen from the figures. Even though only one page is described for the sake of simplicity, the description also applies to the opposite mirror-image side of the containers 2, 3.

Figure 2 shows a perspective view of the transport system 1 of Figure 1 with two spaced apart containers 2, 3. As can be seen from the illustration shows the cover part 9 of the lower system container 3 has two spaced apart parallel guide rails 14, 15, which are designed for the positive reception of the upper container 2. The guide rails 14, 15 extend over the entire depth of the cover part 9 and are also spaced from the opposite side walls, in particular the corresponding coupling elements formed there formed on the cover part 9. This ensures that the lower system container 3 as required with the slightly smaller upper container 2 by means of the guide rails 14, 15 or alternatively by means of the described with respect to the upper container 2, but the lower system container 3 identically formed coupling elements with other identical Systembehältem is connectable.

The guide rails 14, 15 each have a catwalk 16, 17, which extend horizontally and thus parallel to the top cover and in the direction of each other by the guide rails 14, 15 protrude. Corresponding to this, the upper container 2 on the opposite side walls of the bottom part 4 depending on a running rail 18, 19, which are formed, the catwalks 16, 17 of the guide rails 14, 15 holding vertically behind.

The connection of the container 2, 3 takes place in such a way that the upper container 2 with the rails 18, 19 is inserted into the guide rails 14, 15, so that the rails 18, 19, the catwalks 16, 17 engage under. The rails 18, 19 are formed by the bottom plate edges of the bottom part 4 of the upper container 2, which project laterally from the opposite side walls of the bottom part 4. In order to prevent inadvertent release of the upper container 2 from the lower system container 3, a locking device for locking the upper container 2 is provided in an inserted rear locking position relative to the lower system container 3, which is attached to the cover part 9 of the lower system container 3 Arretiemase 20 and a fixed to the bottom part 4 of the upper container 2 locking stop 21 comprises. In the embodiment shown, in each case an arresting lug 20 is arranged on the guide rails 14, 15 and in each case one arresting stop 21 on the rails 18, 19, so that the described mirror-image construction of the containers 2, 3 is maintained. In the embodiment shown, the guide rails 14, 15 have a front open end and an opposite rear closed end, so that the insertion of the upper container 2 can only take place from the front. The Arretiemasen 20 are integrally formed at the open end of the guide rails 14, 15 at the top of the catwalks 16, 17 and project vertically upwards. Complementarily, the locking stops are formed in a side recess of the corresponding side wall of the bottom part 4, which is shown by way of example with reference to the locking stop 21 in the side recess 22. The locking stops are like the locking stop 21 in the side recess 22 vertically downward.

In order to ensure a secure locking of the upper container 2 in the guide rails 14, 15 of the lower system container 3, the locking stops 21 are just so far down that the distance between the upper edge of the rails 18, 19 and the lower edge of the locking stops is greater Thus, for dearreturning in the retracted position, the upper system container 2 can be raised in a front section, for example on the carrying handle 7, and thus tilted about an axis transverse to the withdrawal direction, so that the Arretieranschläge 21 can be raised over the locking lugs 20 and moved away. For a simple insertion and locking of the upper container 2 can also be provided that the Arretiemasen 20 and / or the locking stops 21 in the insertion direction have a flattening, which in contact of Arretiemasen 20 and locking stops 21 during insertion to an automatic lifting of the upper system container 2 lead and thus the Arretiemasen 20 can be overcome particularly easily by the Arretieranschlägen 21 during insertion process.

As can be seen further from FIG. 2, the lower system container 3 has no further carrying handle between the guide rails 14, 15, as is provided, for example, in the upper container 2 in the form of the further carrying handle 23. In an alternative Ausfühmngsform, however, such a further carrying handle may be provided at the lower system container 3 between the guide rails 14, 15.

Figure 3 shows a perspective view of another transport system 1 with two spaced apart alternative containers 2, 3. In contrast to the previously described Ausfühmngsform here have the catwalks 16, 17 of the lower System container 3 each have a recess 24a, 24b. The other elements are identical to the previously described embodiment and provided with the same reference numerals. As in the first embodiment in Figures 1 and 2, the rails 18, 19 are each interrupted by a recess in which the coupling device is arranged, as exemplified by the recess 25 can be seen on the slide rail 18, in which the coupling device 12th is arranged. A particularly rapid attachment of the upper container 2 to the lower system container 3 can in this case take place in that the rails 18, 19 of the upper container 2 does not have to be inserted over the entire length of the catwalks 16, 17, but only to a smaller extent. Thus, in this embodiment, the rear portions of the rails 18, 19 are vertically inserted from above through the recesses 24a, 24b in the guide rails 14, 15 and then inserted to the locking position in the insertion direction along the guide rails 14, 15. Advantageously, the recesses 24a, 24b are arranged approximately centrally between the front open end and the rear closed end of the guide rails 14, 15, so that over the front and rear portions of the catwalks 16, 17 equally holding force is transferable. For ease of assembly it is provided that the length of the recesses 24a, 24b in the direction of insertion at least the extension of the rear portions of the catwalks 16, 17 corresponds, allowing a vertical insertion. However, it may also be provided that the length of the recesses 24a, 24b is less than the extension of the rear portions of the catwalks 16, 17, so that insertion is possible only at an angle by tilting.

In an embodiment, not shown, it may also be provided that the coupling devices 12 in the retracted locking position with corresponding counter-elements in the guide rails 14, 15 cooperate, so that thereby an additional or alternative locking device is formed. This can be solved in a known manner by compressing the coupling devices 12. By corresponding inclined sliding surfaces can also be provided that the coupling devices 12 automatically engage in corresponding counter-elements, such as traps, when the upper container is inserted into the rear locking position. In this way, the already existing coupling devices 12 in addition to the mutual locking similar system tray can be used intuitively for releasable fixation on the guide rails 14, 15. In addition, in the embodiments shown also on the cover part 5 of the upper container 2.2 also guide rails corresponding to the guide rails 14, 15, but only with a smaller mutual distance, be arranged so that on the upper container 2, 2 another smaller system container stackable and attachable. About the other carrying handle 23 of the upper container 2, 2 and the carrying handle of the uppermost container so that the entire transport system can be easily grasped and transported.

A further embodiment of the invention is shown in FIG 4. In this embodiment, a further guide rail 27 is arranged between the two guide rails 14 and 15 and parallel to this, which is also equipped with Faufstegen 28 and 29, the cover part 9 of the lower system container 3, the the Faufstegen 16 and 17 of the outer guide rails 14 and 15, respectively. In this way, a plurality of smaller upper container side by side on the cover part 9 of the lower system container 3 can be fixed.
