Abstract

The trunk (1) has a set of intermediate base plates (16a, 16b), which are rotatably fastened to inner sides of side walls (5a, 5b) in such a manner that the base plates are tiltable between a horizontal, activated position and a vertical, deactivated position. A set of double level bars runs in a set of bar rails, which run at opposite side walls. A roller conveyor (2) is fixed in a deep end position and a high end position, where the intermediate base plates are downwards rotatable from the horizontal position into the vertical position.

Description

I. Field of application

The The invention relates to a change case according to the preamble of the claim 1.

II. Technical background

at Constructions for Trucks, especially on exchangeable cases, the interior design is aimed according to the intended application. Just in the general cargo traffic to be able to use a change case variably, has already been tried to combine several types of use: For simplified storage from Z. B. packages in the exchange case, it is already known, a longitudinal running roller conveyor z. B. to arrange in the bottom of the exchange case, extending along the longitudinal center extends.

In the US 2,411,133 A is a roller conveyor arranged in the floor, which is fixable at least in a deep, deactivated end position and in a high, activated end position. Furthermore, from the DE 44 31 141 A1 a raised roller conveyor is known, which consists of a first and a second section, wherein the first section can be pushed under the second section, so as to save space.

At the Loading boxes or packages at the open back end of the Change case placed on the roller conveyor and by hand so far accelerates that they roll automatically to the front end of the roller conveyor, if the exchangeable case is not loaded there yet.

For the package traffic with individual, different sized packages, it is also known by on the side walls fastened, in particular fold-up, false bottom plates by folding down into the horizontal position an intermediate floor to create the piece goods in two layers, So on the actual floor and on the shelf, store to be able to. Partially was up the false floor also a roller conveyor available.

Furthermore, the double-decker insert was already known, if standard pallets were loaded:
Here are mounted on a selectable intermediate height, which allows a laying a filled standard pallet both above and below, in defined longitudinal distances from the left to the right side wall continuous double-decker beams whose distance in the longitudinal direction corresponds to the length of the standard pallets.

The Standard pallets are only with their front and rear End deposited on one of the double-decker beams, of which he thus two abutting each other Standard pallets in the longitudinal direction bears, in width next to each other according to the vehicle width usually two or three standard pallets, depending on whether the pallets are in longitudinal or Transverse direction are applied.

there is the change case from front to back always at the same time filled up and down, because of lack of continuous false floor loading area of the forklift pallets only on the bottom of the swap body can approach. Accordingly, the required double-decker bars are also in the same Rhythm from front to back mounted or activated, so after To fill the previous section with standard pallets.

The Lower the double-decker bars from their deactivated position below the roof along the beam rails down into the activated Central position, however, was folded up when deactivated False bottom plates not possible then these over the middle, activated level of the double-decker beams protruded.

III. Presentation of the invention

a) Technical task

It is therefore the object according to the present Invention, a cost-effective To create a change case, which can be used for both double-deck use as well as intermediate floor use using a roller conveyor allowed, with the conversion easy to perform is.

b) solution the task

These The object is solved by the features of claim 1. advantageous embodiments emerge from the dependent claims.

By the presence of double-decker beams on the one hand and one in the height adjustable roller conveyor on the other hand, the exchangeable case both in double-deck operation for Package loading are used, for then preferably the Roller conveyor is lowered into the deep end position, so that too lower level is usable by means of pallets, or for package loading be used for then the double-decker rails disabled, so under the roof parked, and the roller conveyor in the high end position and thus spent in the activated position and for the forward transport the packages in the swap body can be used.

Thus, the roller conveyor does not interfere in the deep end position even with double-deck operation, has the Bottom of the case a recessed track gutter, in which the roller conveyor is completely sunk in its deep end position. The track gutter can be covered by gutter covers, so that then a flat, even drivable, floor surface results on the z. B. loaded by forklift or a lifting device standard pallets can be parked.

These Trough covers are preferably on the side of the web gutter attached by hinges and are opened to open on one side and deposited on the surrounding soil.

Of course they can Gutter covers also without hinges be laid loosely on the gutter in positive fit therefor provided lateral shoulders.

The Web gutter is preferably located in the longitudinal center of the exchange case and extends over the entire length the bottom of the suitcase. The roller conveyor on the other hand reaches in the activated, in the high end position folded up, from the open end not to the front end of the exchange box, but ends in a pivot distance in front of the front end that is needed around those on articulated supports then standing roller conveyor Completely accommodate by folding to the front in the railway channel to be able to.

To For this purpose are the supports articulated about transverse axis with its lower end on the floor of the railway channel and fastened with its upper end on the underside of the roller conveyor and designed so that in the folded state over the vertical position can not be worked out, but in this activated Location are fixable.

Around at the height The fold-down, activated roller conveyor can conveniently take off parcels to be able to can additionally an intermediate floor at height of Roller conveyor are created, which then covers the entire area inside covering the exchange case around the roller conveyor. This is achieved by articulating intermediate bottom plates on the insides of the side walls are attached so that they are activated between a horizontal Able and one vertical, in particular hanging down along the side walls deactivated position are pivotable and have a length in the activated Location the transverse distance between the roller conveyor and the inside the side wall covered.

To are not the intermediate bottom plates at their wall end only articulated but preferably also movable in vertical Intermediate floor rails guided and lie with their web - end on the side legs of the Roller conveyor on.

In longitudinal direction Close the exchange case in the activated state, the intermediate bottom plates as possible close together and thus form a continuous surface.

The longitudinal free space between the front end of the activated, folded up Roller conveyor and the front wall of the Wechselkoffers covered in the same way and Way a central plate that works like the false bottom plates, However, attached to the front wall of the change case and up extends to the front end of the roller conveyor and is placed there.

in the disabled state - before all to avoid rattling - the false floor panels with its web-end towards the bottom or the bottom Fixed at the end of the side wall. They lie close to the side wall and are viewed in the plan between the intermediate floor rails, opposite those they are hinged, taken up and have at their front and rear end edge - in Direction of the exchange case considered - one forward or backward on the upper edge of the plate projecting spacer leg whose Projection just under half the width of the intermediate floor rails corresponds to the activated State no gap between the individual intermediate bottom plates according to the width of To create intermediate floor rails.

The Intermediate floor panels are opposite the intermediate floor rails guided, by these in their front and rear end one each vertically, ie a slot, extending slot, in which in each case one protruding from the intermediate bottom plate pin, on which possibly a suitable slider sits, protrudes.

The lower end of the guide slot is at height the roller conveyor, and on this lower end of the pin is the Plate in the activated state.

For the deactivated Condition pushes the pin in the guide slot up, until the web-side end of the plate initially out of engagement with the support on the roller conveyor and subsequently Completely can be folded up to the lower area of the side wall.

The intermediate floor rails terminate just above the upper end of the guide slot, and the bar rails also fastened to the side walls for vertically guiding and fixing the double-decker bars extend maximally to the upper end of the guide slots in the intermediate ground rails down to avoid collisions between the two systems.

As well they are in the walls of the exchange case usually inset on the insides or mounted horizontally extending lashing rails, the one Load securing by lashing, especially of piece goods, allow, only in the height range above the intermediate floor rails available, but also in the lower Be mounted area, then preferably only in the area between the intermediate floor rails.

c) embodiments

embodiments according to the invention in the following example closer described. Show it:

1 : the exchangeable case with intermediate bottom,

2 : after folding away the false floor,

3 when lowering the roller conveyor,

4 with lowered roller conveyor,

5 : with covered roller conveyor,

6 : in double-deck use and

7 : Detailed views of the intermediate floor panels.

The 1 show the use of the exchange suitcase 1 with intermediate bottom:
In the ground 6 the exchange case 1 runs in the longitudinal direction 10 on the longitudinal center 10 ' a railway channel 7 which can be covered but is now open to the very forefront. On the floor of the railway gutter 7 sit props 9a , B on, which are formed as juxtaposed double supports and the roller conveyor 2 wear.

The roller conveyor 2 extends from the rear, open for loading by opening the door, not shown, end of the exchange suitcase 1 not quite to the front wall 15 but ends in a swing distance 13 in front of this end wall, the pivoting distance 13 equal to or slightly larger than the length of the columns 9a , b, the longitudinal direction 10 spaced apart are arranged one behind the other.

The longitudinal direction 10 extending support profiles 2a , b of the roller conveyor 2 , in which the lateral ends of the rollers are mounted, consist of an angle section whose horizontal leg of the roller conveyor 2 protrudes laterally outward, and on the to the longitudinal center 10 ' indicative free ends of false floor panels 16a , b rest with their other, outer ends in intermediate floor rails 22 guided and articulated on the inside of a side wall 5a , b are attached.

In the 1 is only one side between the roller conveyor 2 and the side wall 5a , b throughout with intermediate bottom plates 16a , b, whereby a continuous intermediate floor is formed in this half, however, can also in the same way, the left side of the exchange suitcase 1 be equipped with a false floor.

The swing distance 13 from the front end of the roller conveyor 2 to the front wall 15 is also closed in the intermediate floor, in which a to the support profile 2a , b analogous profile in front of the front end of the roller conveyor 2 in the transverse direction 11 extends and on the front wall 15 an intermediate floor central plate 17 in an analogous way to the other intermediate bottom plates 16a , B is attached to the on this cross profile and thus at the front end of the roller conveyor 2 rests.

If all intermediate floor panels on the roller conveyor 2 are applied, this results in one to the surface of the roller conveyor 2 even continuously closed intermediate floor.

However, this complete creation of the false floor is often completed only during the loading, either with increasing loading of the false floor and the space under the false floor with packages 20a , b, ... on both sides evenly from front to back, or first on one side and then on the other side from front to back, such as in 1c shown.

If the intermediate floor is not needed, the intermediate floor plates 16a , b on the insides of the side walls 5a , b spent in vertical position and thus disabled, as in 2 shown.

This is done by - as in the 7a and b - those at the wall-side end of the false bottom plates 16a , B arranged, parallel to the outer end edge of the plate 16 extending and outwardly freely projecting hinge pin 24 protrude into oblong holes that run vertically in the sides of the intermediate floor rails 22 are arranged, which on the insides of the side walls 5a , b are attached.

These are rectangular profiles closed off from the cross-section, their light off stood to each other the actual width of the intermediate bottom plates 16a , b corresponds.

As a result, in the activated horizontal state of the intermediate floor joints in the width of the intermediate floor rails 22 would protrude from the false bottom plates 16a , fore and aft horizontal thighs 16 ' at the height of the top of the intermediate bottom plates 16a , b, whose projection is just under half the width of the intermediate floor rails 22 equivalent.

The intermediate floor rails 22 extend in the vertical direction at least from just below the height of the false floor to at least a height equal to the distance of the extension of the false bottom plate 16a , b measured from the ground 6 out, but in the simplest case, they already extend from the ground 6 out to the highest point mentioned.

In the front and rear directed intermediate floor rail 22 extend the slots 23 for the hinge pins 24 only from the height of the activated intermediate floor to a height which is slightly higher than that vertically against the side wall 15 folded-up shelf plate 16a , b rises to the top.

Starting from the in 7 illustrated activated state of a false bottom plate 16a , b it must be raised only at its outer end, by pushing up their hinge pin 24 in the two receiving oblong holes 23 , whereby first the interior, the roller conveyor 2 facing, end of the plate 16 no longer in engagement with the support profile 2a , b of the roller conveyor 2 stands and can be lowered down, with increasing pushing the hinge pin 24 in the slot 23 until the inside, now facing down, end of the plate 16 on the ground 6 can be put on and secured there.

Once with all the plates 16 was carried out, the in 2 achieved state shown. Only the intermediate floor central plate 17 must still be disabled, which by folding up hinges at the front end of this central plate 17 to the front wall 15 he follows.

Likewise, if necessary, the previously usually the swing distance 13 the railway channel 7 Covering front gutter cover 8a be removed.

If now also the roller conveyor 2 from its high end position, as in 2 is shown, it will be in the railway channel 7 Folded forward, as in 3 shown:
For this purpose, the supports 9a , b of the roller conveyor 2 each at the top under the roller conveyor 2 and at the bottom at the bottom of the track gutter 7 about transverse axes 11 ' pivoted, but can not be pivoted further back in the fully erected position to a stable position of the roller conveyor 2 to cause in the upper end position, because independently can move forward and down the roller conveyor 2 Alone due to the between the front end and the end wall 15 located intermediate bottom central plate 17 and not due to other security elements.

Because the railway gutter 7 preferably to the front end wall 15 goes through completely in the bottom of the railway channel 7 Stored state, the lower end position of the roller conveyor 2 whose front end just before the front wall 15 while the back end is about the length of a prop 9a , b, the swing distance 13 , from the rear end of the exchange case 1 is spaced.

The height of the railway channel 7 is enough for the roller conveyor 2 completely in height.

Around the railway gutter 7 now cover and thus a consistently flat floor 6 to create, the in 4a next to the railway channel 7 on one side over the entire length of the railway channel 7 lying gutter covers 8a , b over the railway channel 7 placed for this purpose against the top of the rest of the floor 6 around the thickness of the gutter covers 8a , b lowered edges 7a , b over the entire length of the railway channel 7 having.

The gutter covers 8a , b are along one side of the railway channel 7 - as best in 4b to recognize - with hinges 14a , b hinged and around the longitudinal direction 10 swiveling and can access the railway channel 7 be folded, resulting in a consistently flat floor 6 as in 5 shown results.

In this state, the removable case 1 be loaded in any way, but only one layer.

However, if filled standard pallets are to be loaded, a double-deck operation is recommended:
For this - see 6 - from the left margin 5a to the right margin 5b across the interior of the exchange case 1 leading, stable double-decker beams 3 about half, each same, height in the exchange case 1 fixed and in such a longitudinal distance that standard pallets each with their front and rear end on a double-decker beam 3 rest, whose width, however, only half cover, so that on each Double-deck bar 3 - up to the first on the front wall 15 - longitudinal 10 two adjoining standard pallets 21 rest.

The one in the longitudinal direction 10 measured distance of the double-decker beams 3 depends on whether the standard pallets 21 should be placed in the longitudinal or transverse direction. In the former case, there are usually three standard pallets 21 space next to each other, in the latter case two, as in the front area of the exchange suitcase 1 of the 6 shown with empty standard pallets.

The later location of the standard pallets 21 must be in advance during the construction of the exchange suitcase 1 be decided because in the desired longitudinal distances of the double-decker beams 3 are also the vertical along the insides of the side walls 5a , b running bar rails 4a , b mounted in which the double-decker beams 3 can be moved vertically and fixed in height.

These extend from the area just above the intermediate floor rails 22 up to the ceiling 18 - or just below the ceiling 18 if the change case has a roll-up door - the change case 1 as the double-decker beams 3 if not needed in a parking position below the ceiling 18 pushed up and fixed there.

The lower end position for the double-decker beams 3 for example, through the lower end of in the beam rails 4a , b vertically extending guide slots can be determined, is chosen so that below the double-decker beam 3 on the ground 6 another lower layer of standard pallets 21 Can find space in 6 only shown in the empty state.

6 further shows that over the height range of the beam rails 4a , b in the longitudinal direction 10 extending between them on or in the insides of the side walls 5a , b lashing rails 25 are recessed, which serve by means of depressions and over extending webs for passing and securing lashing straps or for attaching locking bar.
