Description

The invention relates to containers, in particular as work or living space, according to the generic terms of claims 1 and 2.

For the quick availability of Transportable containers are used today, the inside according to the intended Purpose are equipped, for example with medical Device for the care of injured and sick people or with sleeping places. Such containers may so that they remain portable, not standard dimensions exceed. In addition, the total weight is limited, for example the air pollution on the helicopter or secure on the plane.

To still have a large volume available To be able to provide, containers have been designed (see DE-A-39 11 511), which consists of a main box element and one or two additional box elements exist, with the additional box elements during of the transport nested within the Main box element arranged and on site from the main box element to two opposite Pages are extendable, which extends the floor area almost triples. The additional box elements have rigid walls and are each open to the main box element.

These types of containers can be passed through seal the corresponding sealing elements easily and well, what especially for use in military Area is important. However, they have the disadvantage that after pushing out the additional box elements, level differences between the floors of the main box element and additional box elements exist. In the known solution, they are compensated by that in the extended state of the additional box elements correspondingly high floor slabs in particular be placed in the main box element. Apart from the fact that the usable height in Main box is restricted, hinders one such solution also the setting up of medical Devices, cabinets or the like.

A generic container is the BE-A-491 328. It also has a main box element as well as one or two additional box elements which are extendable from the main box element, to enlarge the container. The respective Additional box element after extending the main box element detached from it and lowered so that the bottom wall of the main and Additional box element to be at the same height come. When the container can be transported again , the additional box element must be raised and be inserted into the main box element. How the raising and lowering should take place not to be found in the document.

The invention has for its object a To design containers of the type described in the introduction that the provision of the container with extended Additional box element faster and easier can be carried out.

This object is achieved according to the invention solved the characteristics of claims 1 and 2.

The basic idea of the invention is To use additional box elements with rigid floors, which is also during the extension and retraction keep well sealed in the main box element let and which are made simple and stable can. Lifting devices ensure that the additional box elements be raised before or when retracted into the main box element, and vice versa for the fact that when the Additional box elements are lowered so far that the floors of the main box element and additional box elements lie in one plane.

In a further embodiment of the invention suggested that for each additional box element extendable guideways are provided, for example in the form of rail supports, and the additional box elements Have roles when moving the additional box elements over the guideways roll. There is a simple form of Lifting devices or a part thereof in that the guideways slope downwards to lower the additional box elements at Extend or have to lift when retracting. This can expediently be done in such a way that at the beginning and at the end of each guideway Inclined steps are provided and that the additional box elements outside roles that around the height of the inside inclined step is lower are as the inside roles. This ensures that the respective additional box element under Extends maintaining its horizontal position and both just before reaching the end position Inclined levels are reached and then at the same time rolls down.

Alternatively, it is provided that the guideways consist of beams and rail elements, the rail elements via lifting devices are vertically movable. Such lifting devices can each over the length of the rail elements distributed and via a common spindle drive be coupled. It lends itself to the spindle drives to connect via a common drive shaft that preferably at the free ends of the guideways is arranged.

According to a further feature of the invention it is provided that the lifting device lowering elements has that when opening the relevant additional box element lowering due to gravity enable and furthermore at least a resistance element to delay the lowering movement of the additional box element is present.

The lifting devices are designed so that the additional box element that up to a starting position extended from the main box element is from this starting position via lowering elements especially without further manual operation in particular up to the level of the end position of the additional box element is lowerable. A special resistance element, the one essentially contrary the lowering direction acting on the additional box element Resistance creates, prevents the additional box element when lowering over the Measures accelerated so that when braking when reaching only slight vibrations occur in the end position.

The resistance element can be a spring and in particular have an elastic coil spring. If the spring hardness and the length to the expected Load from the additional box element is adjusted, bumps when lowering the additional box element effectively avoided. It is also special advantageous that when lowering the additional box element energy is stored in the spring used when retracting the additional box element can be. Lifting the additional box element when entering is because of the effect the spring supports.

The resistance element can also also an attenuator, such as an as Gas pressure damper or oil damper designed friction damper exhibit. This makes it special quiet lowering of the additional box element achieved.

In a further embodiment of the invention Extendable guideways for each additional box element provided, the additional box elements Have roles that when moving the additional box elements roll over the guideways, and where the guideways outside, movable end areas to lower the additional box elements, each with at least one resistance element stay in contact. The end areas of the guideways represent part of the Lifting devices according to the invention, so that Additional box element with a roller on the end area rests against the resistance of the End area related resistance element is gently lowered.

The resistance elements are on or arranged in the guideways, wherein they are preferably extend in the longitudinal direction of the guideways. This ensures that the resistance elements do not take up any additional installation space, so that the provided according to the invention Lifting device is particularly compact.

The ones provided on the outside of the guideways Lowering elements are according to the invention from a horizontal starting position to a downward position inclined end position can be lowered, the end regions advantageously pivotally mounted downwards are. Such training ensures that at the bottom of the auxiliary box element intended roles over the horizontal Guideways reach the end areas and only from there by swiveling the lowering elements be lowered into the end position.

If the lowering elements on the outside each a stop for a role of an additional box element have the guideways advantageously from the role at the stop the additional box element when extending the additional box element with extended. This makes it special faster container construction possible because the guideways are not separate from the additional box element need to be extended. In addition is precise guidance of the additional box element by the stop possible when lowering.

The weight of the additional box element in question and the properties of the resistance element are preferably coordinated so that the associated lowering elements essentially lower only when a roll of the additional box element when fully extended the guideway reaches the stop. The The guideway then remains together with the lowering elements in a horizontal position until the additional box element almost completely from the Main box element is extended so that the floor the additional box element also during assembly of the container in a horizontal position remains.

In a further development of the invention, the lowering elements guided with lowering mechanisms that are designed so that the end areas when they are lowered a combination of translational movements especially in the downward direction and pivoting movement To run. This can be done, for example done that the lowering mechanism is a combination from a sliding guide both in the longitudinal direction of the guideways as well as in the lowering direction of the additional box element and from a swivel for pivoting in a direction transverse to the Has guideways. According to the invention, the Lowering mechanism, however, as a slide guide one guide groove and one in each Guide groove movable molded cams. This configuration results in a more precise kinematic Relationship between translation and Swiveling the lowering elements, what in the design with sliding guide and swivel joint only with high construction effort is to be achieved. The shape cam is according to a preferred embodiment attached to the pivotable lowering element while the guide groove is provided on the guideway is.

In a particularly preferred embodiment is the backdrop guide according to the invention provided that the cooperating guide surfaces of guide groove and molded cam each as Sub-segments of circular rings with matching Radii are formed. Such a backdrop tour is particularly easy to manufacture.

In a further embodiment of the invention the guideways each sloping outwards Inclined steps as lowering elements for lowering the Additional box elements. Then when the scenery tours are designed so that one in the end area roll of the additional box element lying against the stop makes a movement when lowered, which with the movement of at least one in the area of one Oblique role of the additional box element matches, there is a particularly precise Lowering of the additional box element. In particular in one embodiment, in the beginning an inclined step is provided for each guideway and in which the additional box elements roll on the outside have the depth of the inclined step lower are arranged as the inside roles, the remains Bottom wall of the additional box element when sinking always aligned horizontally.

In an embodiment of the invention, that each have a resistance element at one end with a Guideway is connected, with a rope connection for connecting a lowering element to the serves other end of the resistance element. Thereby there is a particularly simple structure of the containers according to the invention.

Finally, it is provided that the lifting device one between each additional box element and main box member extending, manually actuatable winch especially for retracting the additional box element has in the main box element. With such a winch, the additional box element can on a simple and energy-saving Drive way into the main box element, in particular when executing the guideways with Incline the winch to overcome the incline serves. Alternatively, the winch can also be used for Lowering an additional box element can be used.

The container shown in Figures 1 to 5 1 has a cuboid main box element 2 and two additional box elements 3, 4. The main box element 2 has two end walls 5, 6, two Side walls 7, 8, a ceiling wall 9 and one Bottom wall 10. The side walls 7, 8 have openings 11, 12 to the cross sections of the additional box elements 3, 4 are adapted.

The first additional box element 3 has one Side wall 14, two opposite end walls 15, 16 and a bottom wall 17 and one Ceiling wall 18. For the second additional box element 4 applies accordingly, i.e. here are also a side wall 19, two opposite end walls 20, 21 and a bottom wall 22 and a ceiling wall 23 available. The additional box elements 3, 4 are in the transport state of the container 1, as he results from Figures 1 and 2, completely in the Main box element 2 retracted, in such a way that that the side walls 14, 19 are flush with the side walls 7, 8 of the main box element 2 lie. The additional box elements 3, 4 are nested, i.e. the second additional box element 4 retracted into the first additional box element 3. For this is the second additional box element 4 dimensioned so small that it is straight in the first additional box element 3 fits. The second additional box element 4 has an entrance door 24 in its end wall 21 on.

There are guide tubes in the bottom of the main box element built-in. There is a in these guide tubes extendable rail system installed, of which in 1 on one side four rail supports 25, 26, 27, 28 can be seen in the extended state. they are for supporting the first additional box element 3 determined when this is extended. A corresponding one Rail system exists for the support of the second additional box element 4 and is to the opposite Extendable to the side, as shown in Figure 3 is seen. In this view are the four rail supports, of which only the front rail support here 29 can be seen in a row. The rail brackets everyone Side are connected to each other by a connecting profile 30 connected.

As can also be seen from FIG. 1, the outer rail supports 25, 28 of stabilizing supports 31, 32 flanked. You are appropriate the arrows shown can be pivoted about vertical axes and serve when pulling out the rail supports 25, 26, 27, 28 as a guide and for interception the loads acting on the rail supports 25, 26, 27, 28. In this way, an additional one can usually be found Support and leveling of the rail supports 25, 26, 27, 28 to the floor are dispensed with. The fold-out stabilizer bars 31, 32 guarantee an absolute parallelism of the extendable rail supports 25, 26.2 7, 28 to the bottom wall 10 of the main box element 2. At the same time, the second additional box element 4 when extending on the side of the stabilization bars 31, 32 out. It is understood that corresponding for the opposite rail system Stabilizing beams are provided.

The additional box elements 3, 4 are supported their undersides on roller systems. Here is for each rail support 25, 26, 27, 28, 29 a roller system provided, of which only in Figures 2 to 5 one roller system can be seen. The first additional box element 3 is four apart per roller system support rollers 33 lying at the same level with one another, 34, 35, 36, which cover almost the entire width of the Containers 1 are distributed. In addition there is an outer Support roller 37 is provided in the area of the side wall 14, which are somewhat lower than the other support rollers 33, 34, 35, 36 is arranged.

The second additional box element 4 has pro Roller system also four across its width on the same Height distributed support rollers 38, 39, 40, 41. additionally are two additional support rollers 42, 43 on the outside arranged at a lower level than the support rollers 38, 39, 40, 41 lie, the outermost support roller 43 is at the lowest level.

The bottom wall 10 of the main box element 2 is in the area of its side walls 7, 8 from the outside slopes 44, 45 limited. According to Figures 2 to 5 is on the right side additional a triangular bar 46 is provided which is removable rests on the bottom wall 10 and its right-side sloping surface also the right-side Sloping 45 of the bottom wall 10 continues upwards. The height of the triangular bar 46 corresponds to that the bottom wall 17 of the first additional box element Third

Pulling out the additional box elements 3, 4 happens as follows. First, the stabilizers 31, 32 in the position shown in Figure 1 swung. Then the rail supports 25, 26, 27, 28, 29 extended on both sides. On them rails 47, 48 are attached. After that, first pushed out the second additional box element 4. The support rollers 38, 39, 40, 41 roll here on the bottom wall 17 of the first additional box element 3, while the outermost support rollers 43 on the rails 48 run. The level difference corresponds between the top edges of the rails 48 and the top of the bottom wall 17 of the first Additional box element 3 the level difference between the outermost support rollers 43 and the support rollers 38, 39, 40, 41. In this way, the second additional box element moves 4 initially remain horizontal, d. H. there is no canting.

Shortly before the end of the extension movement the second additional box element 4 only from the outermost Support rollers 43 and the innermost support rollers 38 carried. The rail supports point at their outer ends 29 and thus also the rails 48 to the outside descending inclined steps 49. The inclined steps 49 are reached by the outermost support rollers 43, if the innermost support rollers 38 in front of the outside Bevel of the triangular ledge 46 and the bevel 45 the bottom wall 10 are. When extending further simultaneously move the innermost support rollers 38 over the Triangle bar 46 and the slope 45 and the outermost Support rollers 43 down the inclined steps 49. As a result, the second additional box element lowered while maintaining its horizontal position and now also the support rollers 39, 40, 41, 42 come to rest on the rail 48. Here is the Dimension the height of the upper edge of the rails 48 so that the lowering takes place so far that the tops the bottom walls 10 of the main box element 2 and the bottom wall 22 of the second additional box element come to an equal level.

Following this, the first additional box element 3 are extended, the outer Support rollers 37 initially alone on the rails 47 support the rail support 25, 26, 27, 28. there corresponds to the level difference between the outer ones Support rollers 37 and the other support rollers 33, 34, 35, 36 the level difference between the top edges the rails 47 and the top of the bottom wall 10 of the main box member 2. This causes also the first additional box element 3 while maintaining extends its horizontal position. The rail supports 25, 26, 27, 28 and also the ones lying on it Rails 47 also have free ends outward sloping steps 50, with their Distance to the slope 44 of the bottom wall 10 is dimensioned so that the innermost support roller 33 Bevel 44 and the outer support roller 37 the inclined step Reach 50 at the same time and also over at the same time both roll off. This lowers the first additional box element 3 so far that the support rollers 33, 34, 35, 36 come to rest on the rails 47. The height the upper edge of the rails 47 is dimensioned such that the lowering takes place to a level at which the top the bottom wall 17 of the first additional box element 3 at the same height as the top of the bottom wall 10 of the main box element 2 to lie comes.

After removing the triangular bar 46 is a themselves about both additional box elements 3, 4 and that Main box element 2, flat floor created. Possibly for the main box element 2 certain and in the second additional box element 4 assembled devices, for example an operating table, can then over rails not shown here after releasing a lock in the main box element 2 pushed and fixed there.

The insertion of the additional box elements 3, 4 happens essentially in reverse. As far as 2 devices mounted in the main box element are, these are about those already described above Rails inserted into the second additional box element 4 and fixed there. Then the triangle bar 46 placed on the bottom wall 10. Subsequently first with traction means not shown here the first additional box element 3 in the main box element 2 retracted. The inclined steps ensure this 50 and the slope 44 that the first additional box element 3 is raised to a level in which the support rollers 33, 34, 35, 36 on the bottom wall 10 of the main box element 2 can roll up. The first additional box element 3 is retracted, when it has reached the position shown in Figure 2.

Finally, the second additional box element 4 retracted. Again, it is rolled up the further support rollers 42, 43 on the inclined steps 49 and the innermost support rollers 38 on the slope 45 and then continued in the form of Triangle bar 46 raised so far that drive the second additional box element 4 into the first one and the support rollers 33, 34, 35, 36 on its bottom wall 17 can drive up.

It is understood that means for fixing the Positions of the additional box elements 3, 4 available are. All-round seals are also provided, the interior of the container 1 even when pulled out the additional box elements 3, 4 with respect to the outside atmosphere keep sealed.

Another container is shown in FIGS. 6 to 12 61 similar structure shown. He has like that Container 1 is a cuboid main box element 62 and two additional box elements 63, 64. The main box element 62 corresponds to that of container 1 and accordingly has a bottom wall 65, a top wall 66, side walls not visible here as well End walls 67. The side walls have matching ones Openings for the additional box elements 63, 64.

The first and therefore larger additional box element 63 has a side wall 68, a top wall 69, a bottom wall 70 and two end walls 71, of which the one in front is cut away. The main box element 62 is first additional box element 63 is open. The second and smaller additional box element 64 also has a side wall 72, a top wall 73, a bottom wall 74 and two end walls 75, the front of which is also cut away is. In the cut shown in Figure 6 The additional box elements are in the transport position 63, 64 nested within each other Main box member 62 with the side walls 68, 72 of the additional box elements 63, 64 flush with the Side walls of the main box element 62 lie.

The first additional box element 63 is resting Support roller systems, each consisting of four in the roll direction support rollers 76 arranged one behind the other, 77, 78, 79, on the bottom wall 65 of the main box element 62. Corresponding support roller systems also the second additional box element 64, respectively consisting of four support rollers 80, 81, 82, 83, wherein it about these support roller systems on the bottom wall 70 of the first additional box element 63 rests. Similar as in the container 1 according to FIGS. 1 to 5 in the bottom wall 65 of the main box element 62 four rail supports on each side - vertical to the drawing level one after the other - arranged, in Figures 6 and 7 and 12 only those present rail support 84, 85 to see are. The rail supports 84, 85 are on each side their outer ends via a box profile 86, 87 connected. The rail supports 84, 85 are after open at the top. There are horizontal lines in them Rails 88, 89 guided, which are vertically movable. How this is done in detail follows from the Description of Figures 9 to 12 below.

In Figure 7, the rail supports 84, 85 are extended, the rails 88, 89 in each case top position. The top edge of the left side Rails 88 are found on the same Level as the top of the bottom wall 65 of the Main box member 62. The right side rails 89 are raised further, so that their upper edges at the level of the top of the bottom wall 70 of the first additional box element 63. In this position of the rails 88 and 89 can initially the second additional box element 64 to its end position be extended. This situation is in figure 7 shown. Then the same can be done with the first additional box element 63 happen. After reaching the end positions are the rails 88, 89 lowered so far into the rail supports 84, 85, that the tops of the bottom walls 70, 74 of the Additional box elements 63, 64 the level of the top reach the bottom wall 65 of the main box element 62. A flat surface is created across the entire width Ground. The situation can be seen in FIG. 8.

For pushing the additional box elements together 63, 64 is reversed accordingly. First, the rails 88, 89 again raised to the levels shown in Figure 7. before may be in the main box member 62 on the Bottom wall 65 mounted devices in the second additional box element 64 inserted and fixed there Service. Then the first additional box element 63 retracted so that the shown in Figure 7 Situation is reached again. Then you can then the second auxiliary box member 64 into the first Additional box element 63 can be retracted. To Lowering the rails 88, 89 then become the rail supports 84, 85 in the bottom wall 65 of the main box element 62 inserted so that the container 61 maintains its original standard dimensions and thus is transportable.

In Figures 9 to 12 are next to the rail support 84 two more rail supports 90, 91 with Rails 92, 93 shown. The rail supports 84, 90, 91 represent U-profiles open at the top, into which the Rails 88, 92, 93 as U-profiles open at the bottom one upstanding rail track 94, 95, Border 96. On the rail tracks 94, 95, 96 is a support roller 79, 97, 98 can be seen.

A drive shaft runs through the box section 86 99 from the outside with the help of a crank 100 can be rotated. Via bevel gear sets 101, 102, 103 becomes the movement of the drive shaft 99 on spindle shafts 104, 105, 106 transferred, each one extend axially parallel within the rail supports 84, 90, 91. In the example shown in Figure 9 acts the spindle shaft 104 via a spindle nut lever mounted on the bottom of the rail support 84 107, which carries a lifting roller 108 on the top, which the bottom of the rail 88 rests. Depending on the direction of rotation the spindle 107 is aligned with the lever 107 up or down, with the rail 88 following it.

The example shown in FIG. 10 acts the spindle shaft 105 onto a in the rail support 90 rotatably mounted lifting wheel 109 and puts it in a Rotation. The lifting wheel 109 is arranged on both sides Bolt 110 with the flanks of the rail 92 connected. This has the consequence that one by one the spindle shaft 105 caused rotation of the lifting wheel 109 one up or down depending on the direction of rotation directional movement of the rail 92 is effected.

In the embodiment shown in Figure 11 the spindle shaft 106 acts on a scissor lifting device 111, which is on the one hand on the floor of the Rail support 91 and on the other hand on the inside the rail 93 supports. Depending on the direction of rotation of the spindle shaft 106 the scissors are closed and thus the Rail 93 raised or it opens and the Rail 93 lowers.

It is understood that several such Lifting devices over the length of the rail supports 84, 90, 91 are distributed and that they are all through the Spindle shafts 104, 105, 106 are driven. The different types of lifting equipment the rails 88, 92, 93 are for illustration only drawn from examples. So far it is understood that in a concrete execution only matching lifting devices be provided.

In Figures 13 to 15 are parts of another container 115 according to the invention shown. The container 115 has a cuboid main box element 116 and two additional box elements 117, 118. From the main box element 116 is in this View shown only a bottom wall 119. As well is only one bottom wall of the first additional box element 117 120 shown while from the second additional box element 118 a bottom wall 121 and an end wall 122 is shown.

In the bottom wall 119 of the main box element 116 guide tubes are provided. In these Guide tubes is an extendable rail system for guiding and supporting the additional box elements 117, 118 when moving out of the main box element 116 installed. In Figures 13 and 14 is only the rail system for the second additional box element 118 shown. The rail system for the second Auxiliary box element 118 has four, in Figures 13 and 14 consecutive rail supports, of which here only the front rail support 123 in complete undressed condition can be seen.

The rail support 123 has on its from Main box element 116 facing away from the end Resetting device 124. The resetting device 124 has a movable end element 125, which is via a link guide 126 can be swiveled up and down is mounted in the rail support 123. The end element 125 stands above one not shown in this view Cable with a first end 128 of a cylindrical Coil spring 129 in connection, in the rail support 123 is performed. A second end 130 of the coil spring 129 is supported on two side walls of the slide guide 126, of which in this view only a sidewall 131 is shown. That way the end member 125 against the action of itself compressing coil spring 129 from its 13 in the position shown in Figure 14 Swivel position downwards.

The second auxiliary box element 118 supports on its underside on roller systems. there a roller system is provided for each rail support 123, in Figures 13 and 14 only that first rail support 123 assigned roller system you can see. The second auxiliary box member 118 has per roller system four at the same distance from each other Support rollers 132, 133, 134, 135 located at height, which almost over the entire width of the additional box element 118 are distributed. In addition there is an outer Support roller 136 is provided in the region of the side wall 122, which is slightly lower than the other support rollers 132, 133, 134, 135 is arranged.

The bottom wall 119 of the main box element 116 becomes an additional box element in the area of your 118 facing end of an outwardly sloping Sloping 137 limited. In addition, is on the top surface of the bottom wall 119 a triangular ledge 138 removably provided, the right-side sloping surface also the right-side Incline 137 continues upwards. The height of the triangle bar 138 corresponds to that of the bottom wall 120 of the first additional box element 117 via the bottom wall 119.

Pulling out the in the main box element 116 retracted additional box element 118 happens at completely in the main box member 116 inserted rail supports 123 as follows. Provided on the main box element 116 stabilizing support for the rail supports 123 are provided, these will be swung out into the extended position. Then it will Additional box element 118 from the main box element 116 pushed out. The outer occurs Support roller 136 with a provided on the end member 125 Stop horn 139 so engaged that when Pushing out the additional box element 118 of the Rail support 123 forcibly extended becomes. The support rollers 132, 133, 134, 135 roll up the bottom wall 120 of the first additional box element 117 from. The level difference between the Top edges of the rail support 123 and the top the bottom wall 120 of the first additional box element 117 corresponds to the level difference between the outermost support rollers 136 and the support rollers 132, 133, 134, 135. In this way, the second additional box element moves 118 remaining horizontal from the Main box member 116 so that it is between these no canting occurs.

Shortly before the end of the extension movement the second additional box element 118 only from those outermost support rollers 136 and the innermost support rollers 135 worn, as can be seen in Figure 13. At a the innermost support roller 135 continues to extend over the triangle bar 138 and the slope 137 after down from. At the same time, the end element 125 pivots under the load of the auxiliary box member 118 and under the one on the innermost support roller 135 on the triangular ledge 138 and the slope created towards the Longitudinal force downwards in the position shown in Figure 14. As a consequence, that the second auxiliary box member 118 while maintaining its horizontal position is lowered and now the support rollers 132, 133, 134 on the rail support 123 come to rest. When swiveling of the end element 125 from that shown in FIG Position is in the position shown in Figure 14 the coil spring 129 compressed so that with progressive lowering of the second additional box element 118 a greater resistance to that Lowering acts on this. This is done lowering in a particularly gentle way. The coil spring 129 is tuned so that the above braked lowering movement with additional box elements take place in a wide weight range can.

The height of the top edges of the rail supports 123 is dimensioned so that the lowering takes place so far that the tops of the bottom walls 119 of the Main box member 116 and the top of the bottom wall 121 of the second additional box element 118 come to the same level.

Following this, the first additional box element 117 can be extended, whereby after Removal of the triangle bar 138 one over both Additional box elements 117, 118 and the main box element 116 extending, flat bottom results.

The insertion of the additional box elements 117, 118 happens essentially in reverse Wise. First, the triangle bar 138 is on the bottom wall 119 put on and the first additional box element 117 retracted into the main box element 116. The first additional box element 117 is retracted, if it is the one shown in Figures 13 and 14 Has reached position.

Finally, the second additional box element 118eingefahren. This is the second additional box element 118 with no closer in this view shown traction means with one on the main box element 116 directed force that the innermost support roller 135 from that shown in FIG Position moved up the slope 137. Thereby the second additional box element 118 is raised. This movement is due to the on the end element 125 acting spring force of the coil spring 129 supports, their force acting on the stop horn 139 acts on the outer support roller 136 and via this into the second additional box element 118 is initiated. Due to the special training of Backing guide 126 ensures that during the movement of the auxiliary box member 118 led up and down the outer support roller 136 will that with the bevel 137 and the triangle bar 138 moving to the top left Support roller 135, the bottom wall 121 substantially always parallel to the top surface of the bottom wall 119 of the main box member 116 remains.

Once the innermost support roller 135 is the top one Edge of the triangle bar 138 has moved also the end element 125 in its in FIG. 13 shown starting position. Then the additional box element 118 on the innermost support roller 135 and rolling on the outer support roller 136 into the main box member 116 inserted, the outer Support roller 136 rolls on the rail support 123. at fully inserted second additional box element 118 are finally the rail support 123 in the Inserted into the bottom wall 119 of the main box element 116, whereupon the container 115 in transportable Condition.

It is understood that means for fixing the Positions of the additional box elements 117, 118 and for fixing the rail support 123 in the inserted Condition are present. There are also round seals provided the interior of the container 115 also when pulling out the additional box elements 117, 118 sealed from the outside atmosphere hold.

Figure 15 shows a detailed representation of the end region of the rail support 123 with the movable End element 125, both in the in Figure 13 shown starting position and in the in Figure 14 shown, pivoted downward position is shown.

The link guide 126 has one in this View of particularly visible mold cams 140 in the shape of a segment of a circular arc rounded at its ends, formed on the side wall 131 is. One also runs on the molding cam 140 circular segment-shaped guide groove 141, which in one Part of the end member 125 is provided. The End element 125 moves when pivoting by moving the guide groove over the molding cam 140, so that there is an obliquely right bottom Translation movement as well as a swivel movement around an axis perpendicular to the plane of the drawing. The pivoting movement of the end element 125 takes place so that the abutting on the homing 139 outer support roller 136 substantially the same movement executes how the on the triangle bar 138 and innermost support roller 135 rolling off slope 137 the end element 125 is formed on its upper side in such a way that it is flush with the top surface of the Rail support 123 closes, so that when inserted of the second additional box element 118 in the Main box member 116 which on the top surface of the end element 125 rolling outer support roller 136 bump-free on the upper surface of the rail support 123 can roll up.

For more rigid training of the scenery guide 126 is a second side wall, not shown in this view provided, the shape of which essentially with the first side wall 131 matches and the over the mold cam 140, via not shown in this view Spacer sleeves and a base plate 142 connected with this.

A guide tube connects to the base plate 142 143 for the coil spring 129. In the guide tube 143 the coil spring 129 is inserted, with its second end 130 on base plate 142 is applied. At the first end 128 of the coil spring 129 is a stop disc 144 slidably into the guide tube 143 used. The stop washer 144 has a through hole 145 through which the threaded end a rope thimble 146 is guided, on the side of the coil spring 129 Stop washer 144 on one end of the thimble 146 two lock nuts 147 are provided. To the the other end of the rope thimble 146 closes a cable 148 through an elongated hole 149 in the base plate 142 via an articulated on the side wall 131 Guide roller 150 is guided and in an eye tab 151 opens with an eye hole 152. The eye tab 151 stands with one through the eye hole 152 extending bolt, not shown in this view connected to the rear end of the end member 125. The length of the cable 148 is with the lock nuts 147 set so that the coil spring 129 when the end member 125 is in the starting position 13 is located under a slight bias.

When the end element is pivoted 125 down, as shown by that in Figure 13 and Figure 14 described lowering of the second additional box element 118 occurs, the eye hole 152 moves the eye tab 151 in the drawing to the right. Thereby becomes the cable 148 and with it the stop disc 144 moved to the right, causing the coil spring 129 is increasingly compressed. When the end element 125 is released, it will snap through the force of the coil spring 129 back to its original position back. After swiveling the End element 125 not only the eye tab in the direction of the longitudinal beam 123, but also across is moved up, ensures the deflection of the Cable 148 on the guide roller 150 that the cable 148 always substantially in the area of the coil spring 129 runs parallel to its axis of symmetry, so that both a frictional contact between the cable 148 and base plate 142 in slot 149 as well Tilting the stop disc 144 in the guide tube 143 is avoided.

The link guide 126 is over in this view screw connections not shown by the Side walls 131 connected to the rail support 123. To replace the link guide 126, for example if the coil spring 129 by a Coil spring with a different hardness can be replaced the screw connections between Side walls 131 and rail support 123 released, whereupon the link guide 126 together with the guide tube 143 and the scenery guide 126 and the components provided in the guide tube 143 the rail support 123 can be pulled out, in particular when inserted the additional box element 118 and the rail support 123 in the main box member 116.
