Description

The invention relates to a stackable container for forming a container stack of stacked and in particular coupled containers along a vertical stacking axis according to the preamble of claim 1 and a base plate for forming the container stack according to the preamble of claim 21 and accessories for forming an upper end of the container stack.

From the EP 2013099 B1 a stackable container is known, with which it is possible to form a container stack, wherein the stacked containers can be coupled together. As a connection elements in the bottom area, such a container has a circumferential collar with at least one locking device. As a locking device, such a container has a hinged snap hook, which engages for locking behind a corresponding counter-locking edge in the ceiling region of a second container. A carrying transport of two such containers is only possible if the locking device, that is the snap hook (in the EP 2013099 B1 with the reference number 11 designated) is reliably locked. In the snap hook is a movably mounted with respect to the container component which is exposed in everyday use such stackable boxes high loads and thus subject to high wear. It has been observed that such movable locking elements have an increased probability of failure.

In case of failure of the locking element is a stacking connection of two containers according to the EP 2013099 B1 no longer so possible that a vertical upward lifting or lifting force can be transferred from a container to an underlying container. A common transport of several stacked containers is thus no longer guaranteed.

In addition, in a container according to the above-mentioned document, the locking device must be designed so stable and solid that it is able to accommodate high weight forces of several stacked containers can.

Furthermore, it is disadvantageous in such a container that for releasing the connection of two containers, these have to be tilted relative to one another. For this purpose, especially if the container as a stackable Werkbehälterturm in a motor vehicle z. B. a service vehicle are installed, not always the necessary space available. Usually, such container towers are arranged in such service vehicles near the vehicle wall of a box body. Thus, a partial container stack according to the EP 2013099 B1 have a certain clearance in a tilting direction to even reliable stacked and separated from each other. This makes an increased space requirement in the vehicle necessary.

The object of the invention is therefore to provide a stackable transport container, with which the formation of a container stack is possible and is designed to be particularly robust and resistant in everyday operations. A further object of the invention is to keep a container movable in the stacked state locking device of weight forces in the vertical direction.

Furthermore, it should be ensured that even with a failure of a locking device still a carrying transport of a container stack formed from a plurality of containers is possible.

These objects are achieved with a stackable container having the features of claim 1. Advantageous embodiments are specified in the subclaims.

According to the invention, a stackable container for forming a container stack along a vertical stacking axis has a plurality of stackable containers with a body having at least one container bottom and a container cover, wherein the body has connecting elements on the bottom side for forming a connecting device, which cooperate with counter-connecting elements in the region of the container ceiling a second stackable container are formed and the container has a with respect to the body movably mounted locking means for cooperating with a counter-locking device of the second stackable container, such that each of the connecting elements and the counter-connecting elements immovable with respect to the body are formed and the connecting means alone at least for positive locking Recording of vertical tensile forces is formed. According to the invention, therefore, in particular the absorption of vertical tensile forces, which occur forcibly when a container stack is lifted at its uppermost container, are transferable from one container to the other solely by the connection means. According to the invention, the locking device is not involved in such a force transmission, which preferably also concerns at least tilting moments about spatial axes perpendicular to the stacking axis. The connecting device is designed rigidly with respect to the body, so that the connecting device does not have any parts which are movable relative to the body, which are subject to increased wear in everyday life, has.

According to an expedient embodiment of the invention, the connecting device is engageable by an exclusively translatory engagement movement along an engagement movement direction perpendicular to the stack axis of a first container relative to the second container. This means that first a container is placed with its bottom on the ceiling of a second container and engage only by translational displacement movement of a container relative to the other container, the connecting means and thus provide a connection that can transmit vertical tensile forces along the stacking axis.

For this purpose, the connecting elements are preferably hook-like projections and the counter-connecting elements pocket-like recesses. However, it is alternatively also possible to form the connecting elements as pocket-like recesses and the counter-connecting elements as hook-like projections. Thus, the connecting device may be designed in the manner of a linear bayonet closure and / or be formed at least for receiving tilting moments about spatial axes perpendicular to the stacking axis.

For power transmission in the vertical direction, that is to say in the direction parallel to the stacking axis, the connecting elements and the mating connecting elements expediently have active surfaces and counter-acting surfaces which can transmit forces in engagement in a form-fitting manner parallel to the stacking axis. Here, the terms "active surfaces" and "counter-acting surfaces" is also understood to mean web-like formation in which geometrically no planar elements interact but, for example, the connecting elements and the counter-connecting elements interact in the form of line contact or point contact.

In a further advantageous embodiment, the locking device is designed as a detachable latching connection with at least one locking element and at least one counter-locking element and configured such that by means of the locking device, a relative movement of two containers to each other at least against the translatory engagement movement can be blocked. With such an embodiment of the locking device, it is thus possible to block only the engagement movement, which is necessary for the interaction of the connecting device, in their opposite direction. However, the locking device itself is not involved in the load transfer in the vertical direction or on a load receiving due to tilting moments of two containers to each other, which are aligned at least about a spatial axis perpendicular to the stacking axis. The locking device thus preferably represents only a barrier for a translational movement against the engagement movement.

For example, the locking element is a locking slide with locking projections, which is displaceable for locking and unlocking parallel to the stacking axis.

In this case, locking projections may be arranged on the bottom side with respect to the body and counter-locking elements may be arranged in the region of the container ceiling.

In order to facilitate the connection between two stackable containers, the connecting elements of one container and the mating connection elements of the other container may have respective corresponding, inclined to the stacking axis inclined surfaces as determination surfaces, so that the container can be positioned and centered in the stacking process along the inclined surfaces. Optionally, the inclined surfaces are selected with respect to their geometric arrangement and assignment to each other such that by placing a container on a second container according to the invention already engagement of the connecting elements and the counter-connecting elements is generated by the sliding along the determination surfaces.

Conveniently, a container according to the invention has at least two connecting elements and correspondingly at least two counter-connecting elements, which are arranged distributed over the container bottom and the container cover and are designed such that they are capable of at least one vertical force along the stacking axis and moments about spatial axes perpendicular to the stack axis take. Conveniently, the connecting elements and corresponding thereto, the counter-connecting elements can also be designed so that they can absorb all forces and moments with the exception of one of the engagement direction opposite translational force. For receiving this one of the engagement movement opposite direction of force, the locking device is provided.

For ergonomic and convenient operation, it is expedient to arrange the locking slide accessible for actuation on a container side wall, wherein an outer side of this container side wall facing in an opposite direction to the engagement movement.

The container according to the invention is particularly suitable as a stackable plastic container, in particular a stackable plastic tool container and is preferably suitable for equipping workshop vehicles.

The container according to the invention can also be designed as a slide-in frame for receiving drawers.

Of course, it is also possible to form the container according to the invention as a container having a base body and a lid formed as a container ceiling, which forms the body together with a container body, wherein the container lid is positively connected to the container body.

Of course, in the case of a container having a container body and a container lid, the container lid can be closed by means of suitable closure mechanisms with respect to the body. However, these closure mechanisms for connecting the lid to the container body are not used according to the invention to form a connection between two stackable containers in the staple case.

The locking device is expediently designed such that the locking element of the particular container is to be actuated for unlocking a particular container of the container stack from the remaining container stack.

This means that the container or the lowest container of a part stack to be removed has the locking device, which must be actuated to release the connection. Solutions are also known from the prior art, in which a locking device of a subsequent next container must be actuated in order to solve the overlying container can. This is perceived as impractical and is improved with the above-mentioned expedient embodiment of the invention.

Furthermore, it is expedient to form the locking device in particular exclusively for blocking the relative movement of two containers to one another against the engagement movement. These forces are only shear forces z. B. are aligned perpendicular to the stack axis and in terms of amount in everyday operations are rather low, so that the locking device can be constructed extremely durable with little effort. Since no weight forces acting on the locking device and the wear is limited.

The locking slide can be suitably biased resiliently mounted with respect to the container body and when engaging two containers to each other along the engagement movement at a predetermined location in the, z. B. snap as trained counter locking device. Thus, an automatic locking is guaranteed with correct positioning of stacked containers to each other. This facilitates in particular the ease of use when stacking.

Furthermore, the invention relates to a base plate for forming a container stack of stackable containers, wherein the base plate has mating connecting elements and counter locking elements, which are formed corresponding to connecting elements of the container and to locking elements of the container.

In a preferred manner, the base plate fastening means for anchoring the base plate on a ground surface.

In a particularly simple manner, the counter-connecting elements of the base plate and the counter-locking elements of the base plate are formed identical to the counter-connecting elements of the container and counter-locking elements of the container.

It is particularly expedient that the base plate has mating connecting elements and counter-locking elements, which allows a locked placing of a container in the direction of engagement by 180 ° about the stacking axis S (z-axis) turned counter to the direction of engagement.

The invention further relates to accessories for forming a top closure of a container stack of stackable containers, wherein the accessory for forming a connecting device with counter-connecting elements of the container has corresponding connecting elements and a relative to the accessory movably mounted locking element for cooperation with the counter-locking element of the container. Such accessories only need to have on the bottom side of the accessory those elements that are necessary for locking and coupling the accessories with the last upper container.

As an accessory may conveniently be provided a worktop attachment or an open-topped bulk container. According to the invention, the accessory is preferably not provided on the upper side with counter-connecting elements or counter-locking elements.

In the following the invention will be explained in more detail by way of example with reference to the figures. Show it:

1 a stackable plastic container according to the invention in a perspective view, inter alia, on a container ceiling;

2 : the container according to 1 in a perspective view, inter alia, on a container bottom;

3 a section through a container stack of two containers according to the invention in a sectional plane A parallel to a stacking axis (vertical axis, z-axis) containing connecting elements and mating connecting elements;

4 a section through a container stack of two containers according to the invention in a sectional plane B parallel to a stacking axis S (= vertical axis, = z-axis) containing locking elements and counter-locking elements and

5 : a section in the plane A according to 3 by a container according to the invention and a base plate, which serves as a positioning element for a container stack.

An inventive container 1 ( 1 . 2 ) has a container body 2 with a container bottom 3 and a container ceiling 4 , In the present embodiment, the container ceiling 4 as a hinged lid 5 formed, which has an upwardly open container body 6 makes it lockable. The container 1 has two mutually spaced parallel Längsseitenwandungen 7 and two spaced parallel transverse sidewalls 8th on. In the container ceiling 4 or in the hinged lid 5 is a folding handle 9 Arranged out of the container ceiling 4 for the purpose of carrying the container 1 can be unfolded.

For the further description, the following coordinate system is defined:
An x-axis runs parallel to the Längsseitenwandungen 7 , A y-axis is parallel to the narrow side walls 8th and a z-axis is vertically aligned and forms a stacking axis S along the plurality of containers 1 stackable on each other. The x-axis and the y-axis each run horizontally when the container 1 standing on a horizontal surface.

For the purpose of further description, the longitudinal side wall is that 7 , in the 1 and 2 is visible, as a front longitudinal boundary wall 7 Are defined. In the area of the front boundary wall 7 sit lock devices 10 by means of which the hinged lid 5 relative to the main body 6 can be determined. In the area of one of the front Längsseitenwandung 7 opposite Längsseitenwandung 7 is the hinged lid 5 hinged hinged.

Bodenseitig stand from the tank bottom 3 hook-like connecting elements 11 down before. The connecting elements 11 have hook-like bars 12 that of Domen 13 the connecting elements 11 from the front Längsseitenwandung 7 point away. These hook-like bars 12 thus have in the positive y-direction and thus in a - as will be explained in more detail below - engagement direction 14 which is aligned parallel to the y-direction. The dome 13 also point to the bottom of the container 3 outgoing inclined surfaces 15 on, with corresponding inclined surfaces 15a in the container ceiling 4 Finding surfaces for centering and positioning a first container 1 on a second container 1 contribute.

The connecting elements 11 that with the jetties 12 and the Domen 13 as hook-like projections 16 are formed, possess as active surfaces 17 horizontal, that is perpendicular to the stack axis S (z-axis) extending surfaces.

The hook-like projections 16 together with the active surfaces 17 form a connection device 18 in the area of the container bottom 3 , Over the surface of the container bottom 3 are distributed in the embodiment according to the 1 and 2 each 4 connecting devices 18 arranged. The four connecting devices 18 are in corner areas of the tank bottom 3 arranged, in each case two connecting devices 18 aligned with each other parallel to the y-axis and parallel to the x-axis.

In such an arrangement, the connection means act 18 also as leveling feet for the container 1 ,

Corresponding to the connecting devices 18 are in the container ceiling 4 Against fasteners 19 provided, in which the hook-like projections 16 can intervene. For the formation of the counter-connecting elements 19 are trough-like depressions 20 provided, with regard to their distribution over the container ceiling 4 corresponding to the connection means 18 at the bottom of the container 3 are arranged. The wells 20 own in the direction of engagement 14 seen on lateral boundary walls pocket-like recesses 21 into which the footbridges 12 are pluggable. The trough-like depressions 20 are dimensioned in terms of their areal extent in the plan view such that the connecting elements 11 into the wells 20 can submerge, leaving the bottom of the container 3 on the container ceiling 4 seated. In this stacked position can the webs 12 upon a displacement of a first container 1 standing on a lower second container 1 is placed in engagement with the pocket-like recesses 21 are brought when the upper container relative to the lower container in the engagement direction 14 is moved. The dome forms 13 the connecting elements 11 Stops that are positioned such that in a position in which the webs 12 until it stops in the pocket-like recesses 21 retracted, the container 1 a container stack consisting of several containers 1 are aligned over one another.

In this joining position are the active surfaces 17 with corresponding counteracting surfaces 22a ( 3 . 5 ) of the pocket-like recesses 21 For example, their ceiling bars 22 engaged, so that already a so-formed container stack on the carrying handle of the upper container 1 vertical, that is in the z-direction, can be raised without a release of the positive connection takes place in the vertical direction. Through the interaction of the connecting elements 11 and the mating connection elements 19 are thus vertical forces when lifting an upper container 1 on a lower container 1 be exercised, alone by the fasteners 11 and the mating connection elements 19 So the connecting devices 18 collected.

Furthermore, about the distributed arrangement of the connecting devices 18 over the tank bottom 3 or over the container ceiling 4 also tilting moments My about the y-axis and tilting moments Mx supported around the x-axis, so that an upper container 1 standing on a lower container 1 sitting, not alone relative to the lower container 1 can be tilted without tilting this too.

To prevent inadvertent separation of the upper container 1 from the bottom tank 1 by carrying by a carrier to prevent possesses the container according to the invention 1 on its front Längsseitenwandung 7 as a locking device 30 a locking slide 31 , The locking slide 31 is relative to the container 1 stored in the vertical direction (z-direction) resiliently biased and displaced. On its underside has the locking slide 31 locking projections 32 , which is a bottom surface of the container bottom 3 overhanging below. The locking slide 31 and the locking projections 32 are preferably formed in one piece and form a locking element 33 , The locking element 33 , in particular its locking projections 32 act with a corresponding counter-locking device 34 at a top of the container ceiling 4 together. The counter locking device 34 has as a counter locking element 35 groove-like recesses into which the locking projections 32 can snap. Are the locking projections 32 the locking elements 33 in the counter-locking elements 35 resiliently snapped, so is a relative movement of two stacked containers 1 against the direction of engagement 14 prevented. Thus, the upper container 1 a container stack determined statically determined relative to a lower container of the container stack.

If a vertical tensile force F is now applied to the upper container of a container stack and a partial container stack consisting of two or more containers is lifted, then the vertical tensile forces F are produced exclusively via the connecting device 18 that is about the fasteners 11 and the mating connection elements 19 transfer. The locking device 30 remains mechanically unloaded.

The connection device 18 that is, the fasteners 11 and the mating connection elements 19 function by design as a hook and corresponding pocket recess in the manner of a linear bayonet lock. An upper container 1 is first offset to the lower container 1 on the lower container 1 put on, by moving the upper container 1 the connecting elements 11 into the wells 20 plunge.

By an exclusively translatory engagement movement 36 along the direction of engagement 14 get the fasteners 11 with the mating connection elements 19 in operative connection, so that vertical tensile forces F are transferable. Is also the locking device 30 in operative connection with the counter-locking device 34 been brought, so is an unintentional release of the connection between a lower container 1 and an upper container 1 prevented. The containers are statically determined, that is to say also with regard to tilting moments Mx, My about the x-axis or about the y-axis or with regard to torque Mz about the z-axis statically determined connected to each other. In this way, along a stacking axis S, a plurality of containers 1 be stacked, creating a vertical stacking tower.

A stacked situation of two containers 1 shows one above the other 3 in a sectional view through a plane A. The plane A is a plane perpendicular to the x-axis, which the connecting means 11 and the counterconnection devices 20 cuts.

The sectional plane B is a sectional plane parallel to the sectional plane A and passes through the locking device 30 ,

4 shows a section through two stacked containers 1 according to the invention in the cutting plane B.

3 shows two containers according to the invention 1 in section along the plane A in the connected state, that is in a state in which the connecting device 18 are engaged. In this state, the webs under attack 12 the ceiling bridges 22 and thus form in a vertical direction (z-direction) a positive connection for vertical forces F.

To release the connection device 18 , which after unlocking the locking device 30 can be done is the upper container 1 a piece opposite to the direction of engagement 14 opposite the lower container 1 to move until the webs 12 out of engagement with the ceiling bars 22 or their counteracting surfaces 22a get on their subpages. In such a position is the upper container 1 within the trough-like depressions 20 in the illustration according to 3 moved a bit to the left. In this position, the upper container 1 vertically from the bottom tank 1 be lifted off.

The operation of the locking device 30 in interaction with the counter-locking device 34 is based on the sectional view according to 4 along the plane B shown. In a locked state in which the connecting devices 18 are engaged, are locking projections 32 of the locking element 33 in the counter locking element 35 snapped. The counter locking element 35 is a recess for receiving the locking projections 32 , The locking projections 32 and the counter locking element 35 are designed such that they counter to the direction of engagement 14 a relative movement of the upper container 1 relative to the lower container 1 can block. A lifting of the locking slide 31 in the vertical direction, that is in the z-direction, by an operator gives the locking device 30 free, so the above related to 3 described relative movement of the stacked containers 1 for decoupling the connection device 18 is released.

In the invention is of particular advantage that the locking device 30 , in particular by means of the locking slide 31 on that container 1 is operable and unlockable, which is to be unlocked as the only or bottom container of a stack of containers arranged above it from an underlying container. Thus, it is particularly easy for the operator by vertical lifting of the locking element 33 that is the locking slide 31 to accomplish the unlocking. At the same time can be on the operating handle of the locking slide 31 also immediately after unlocking a force against the direction of engagement with the container to be unlocked and to be solved 1 be applied, so that an offset of the upper container 1 relative to the lower container 1 without a subsequent release of the container is possible. Such an arrangement thus greatly facilitates the operability and is an ergonomically advantageous measure. For this purpose, it is particularly advantageous, the locking slide or, more generally, the locking element on that longitudinal side wall 7 or narrow side wall 8th to arrange the container, which is opposite to the direction of engagement 14 has.

With reference to 5 now becomes a connection between a container 1 and a base plate 50 explained in more detail. The base plate 50 thus serves as a basic structure for building a container stack of several containers 1 , being the lowest, directly on the base plate 50 standing containers 1 with the above-described connecting devices 18 and locking devices 30 with the base plate 50 connectable and configured with respect to this lockable. The base plate 50 thus also analogous to the container ceiling 4 Against fasteners 19 on, being in the trough-like depression 20 the pocket-like recesses 21 available. Opposite lying to the pocket-like recesses 21 as they are in 5 are shown has the base plate 50 additional pocket-like recesses 21a so that putting on and connecting the container 1 on the base plate 50 even in a rotated position by 180 ° about the z-axis so opposite to in 5 drawn engagement direction is possible. Corresponding to counter-locking elements (not shown in FIG 5 ) has the base plate 50 additional counter-locking elements, the lock in the twisted position of the container 1 enable.

In the case of the container according to the invention is of particular advantage that it can be easily connected to a stack of multiple containers and also single or multiple containers from this stack ergonomically easy and easy to be solved again. A further advantage is that the type chosen according to the invention for producing a positive connection, at least in the z direction, is rigid and immovable to the container 1 molded fasteners 11 and mating connectors 19 a particularly robust design is possible. The locking device used in the invention is arranged and designed such that it is not loaded with vertical tensile forces in the case of carrying one or more containers locked to each other. Even in the case of a tilting moment My, Mx on one of the containers about a y-axis or about the x-axis, the locking device remains load-free. As a result, they for example, even at a vertical stacked container stack, for example, in a crooked workshop vehicle in which such a stack of containers is arranged for unlocking free of reaction forces is operated, so that the operating forces of the locking device, in particular the locking slide 31 remain constantly low even with an inclination of the tower, as act by the inclination of the tower no forces on the locking device.
