Abstract

The invention relates to a component for a commercial vehicle structure, in particular wall element (10) and / or floor element (11) and / or roof element (12), with at least one functional chamber (13), the holding plate limiting the interior (14) of the commercial vehicle body in use (15), wherein profile openings (16) for receiving fastening means for fixtures, in particular loading bars, locking bars, lashing straps, clothes rails and the like in the holding plate (15) can be introduced or introduced.

Description

The invention relates to a wall element or a roof element for a commercial vehicle body, to a commercial vehicle with such a wall element or roof element and to a method for producing such a wall element or roof element.

Usually, for different transport goods, which are packaged on pallets, in lattice boxes or otherwise, different design variants have to be provided with regard to the attachment and securing.

For example, for goods that can only be stacked on a limited number of panels, load bars are used in deck rails to place a second pallet over a lower first pallet, thus taking advantage of the room height of the structure.

Such a structure is for example from the DE 94 05 528 U1 known to the applicant.

For height-adjustable mounting of the loading beam or support beam, this construction has on the side walls opposite each other arranged vertical rails, each comprising a plurality of slot-shaped pockets. Bolts provided at the ends of the loading bars are hooked into the pockets to allow storage of the loading bars at different heights. The vertical rails are embedded on the inside of the insulated side walls.

Furthermore, the load must be secured during transport against slipping in the longitudinal direction. For this purpose, anchor rails for the use of locking bars are provided in the side walls.

An example of such a construction is in DE 92 06 036 U1 which is also due to the Applicant.

In this document, a horizontal rail is described which comprises a longitudinal channel with two opposite longitudinal grooves for receiving fasteners. On the top and bottom of the rail two extending in the longitudinal direction of the rail receiving slots are provided, in which an upper and lower wall element can be used, so that the rail not only for receiving securing means (locking bars, lashing straps, etc.), but also for Connection of the individual wall elements is used.

If goods are transported that require neither a double-decker load nor a load securing, a smooth side wall is sufficient without the above-mentioned fastening means.

It follows that due to the different transport requirements a variety of different commercial vehicle bodies must be provided in order to meet the respective specific customer requirements. The required modifications increase the planning and production costs significantly.

In addition, many goods require temperature-controlled transport. In particular, for the transport of perishable food, which must be transported deep-frozen in the chain of producers, processors and sellers, as well as for the transport of cold-sensitive goods, insulated box bodies are used. In these insulated box bodies, it is important that a removal of the heat penetrated into the vehicle body takes place before the product itself undergoes a temperature change. This is usually done by means of a fan in a refrigerator, which removes the warmer air and cold air flows into the interior of the structure. Systems are known for better air distribution, which allow the cold air to flow in under the build-up roof by means of suitable distributors and distribute them to the side and to the rear. The cold air introduced at the top of the body falls down and is sucked in again by the blower.

If not correctly loaded, d. H. if the load is applied to the side wall, the washing of the goods is interrupted. To prevent this, side walls are known, which release the way down through a complex profiling or by attaching spacer strips the air flow.

An example of such a construction is in DE 100 29 355 A1 given to the applicant.

Another construction of this kind is in the DE 697 02 740 T2 disclosed. In this case, slot slotted rails are used for the air supply, which are inserted into the inner wall of the structure.

The safe rinsing of the transported goods is achieved by spacers, which are provided on the side walls of the structure.

In the known insulated box bodies thus occurs in addition to the above-mentioned fastening problem, the problem of the safe cooling of the goods. It must therefore be provided in addition to the different fasteners still special cooling systems, which further increases the variety of bodies to be provided.

The invention has for its object to provide a wall or roof element for a commercial vehicle body, which can be prefabricated as independent as possible from the particular customer requirements in particular with regard to the different types of fastening or cooling systems standardized. Furthermore, a commercial vehicle with such a wall or roof element and a method for producing such a wall or roof element to be specified.

According to the invention the object is achieved with respect to the wall or roof element by the subject matter of claim 1 and alternatively by the subject matter of claim 11. With regard to the commercial vehicle or the manufacturing method, the object is achieved in each case by the subject matter of claims 11 and 12, respectively.

The invention is based on the idea of specifying a wall element or roof element for a commercial vehicle structure which has at least one functional chamber with a holding plate delimiting the interior of the commercial vehicle body in use. In the holding plate profile openings for receiving fasteners for fixtures, in particular loading bars, locking bars, lashing straps, clothes rails and the like and / or introduced for the introduction of circulating air in the interior.

The invention has the advantage that a multifunctional component is created, which can be flexibly adapted to the respective customer requirements by slight modifications. In particular, the wall or roof element according to the invention allows a standardized production, whereby the planning and manufacturing costs can be significantly reduced. The wall or roof element according to the invention is generally disclosed as a component and can also be realized as a floor element.

In contrast to the previous constructions, which use conventional fastening means, such as floor rails or anchor channels to store loading bars or locking bars, the wall or roof element according to the invention is based on a completely different concept. Essential for this is the function chamber with the interior of the commercial vehicle in use limiting retaining plate.

In the event that the goods to be transported require neither air conditioning nor fastening or securing means, the holding plate remains unprocessed, so that a continuous smooth inside of the structure is provided. This variant is particularly inexpensive.

In the event that goods to be secured are transported, profile openings for receiving fastening means are arranged in the holding plate. The profile openings are created by milling. This can be done easily and precisely at the factory prior to assembly of the device. The introduction of the profile openings is carried out according to the invention subsequently after the device is mounted in the commercial vehicle body.

The holding plate is adapted to perform a holding function for fixtures, in particular loading bars, locking bars, lashing straps and the like. This means that the holding plate or the functional chamber is sufficiently stable to safely store the aforementioned internals including goods arranged thereon. In the case of the use of lashing straps or locking bars, the holding plate or the entire functional chamber has sufficient stability to accommodate the introduced via the lashing straps or locking rods tensile forces that are finally introduced via the device in the substructure.

Conventional inner cover layers of commercial vehicle structures, for example made of plastic or thin aluminum sheets, do not exhibit this stability and therefore can not be used as a retaining plate in the sense of the invention.

The invention has the advantage that on the commonly used rail rails, anchor rails, u. s. w. can be waived. For securing cargo, only suitable profile openings are introduced into the retaining plate, if necessary, to which the desired installations, for example loading bars or locking rods, are fastened.

The arrangement of the profile openings according to the invention can be chosen freely, so that the placement of the internals can be very flexibly adapted to the particular customer requirements.

In addition, the type of load securing (loading bars, locking bars, lashing straps and the like) can be selected as desired by adapting the shape of the profile openings to the desired attachment or securing.

It follows that the previously required different construction variants can be replaced by a structure with the wall or roof element according to the invention, without having to dispense with the variety of mounting and securing options. The production of commercial vehicle bodies can therefore be standardized, whereby the planning and production costs are significantly reduced.

As an alternative to the use of a functional chamber with a holding plate, it can be provided apart from the invention that the component, In particular, wall element and / or floor element and / or roof element, at least one the interior of the commercial vehicle body defining functional chamber, wherein in the function chamber fastening means for fixtures, in particular rails, perforated plates, brackets, threads and the like are arranged.

Instead of the holding plate are in this alternative in the function chamber conventional fasteners for internals, d. H. Rails, perforated plates, brackets, threads and the like arranged. These fastening means are connected in the function chamber behind a plate bounding the interior of the structure, wherein the plate does not assume a holding function and therefore is not subject to any special requirements in terms of stability.

In order to use the desired fastening means, the plate is locally removed in this alternative only in the region of these fasteners, for example by milling, so that they are accessible from the interior of the structure. The rest of the plate remains in place, so that the unneeded fastening means arranged in the function chamber continue to be concealed.

Due to the factory pre-assembled and exposed as needed fasteners, different customer requirements can be met without major modifications.

Further improvements and structural details of the invention are specified in the subclaims.

In a preferred embodiment of the invention, the holding plate is locally reinforced in the region of the profile openings to be introduced or introduced by connecting webs between the inner sides of the functional chamber.

Since due to the largely standardized load securing (pallet size, height of the grid boxes ...), the arrangement of the internals and thus the arrangement of the profile openings in the holding plate is substantially fixed, it is possible in advance, d. H. prior to introducing the profile openings to strengthen the relevant areas of the holding plate locally. This can be done for example by connecting webs which are arranged between the inner sides of the functional chamber.

Specifically, due to the substantially known position of the profile openings to be introduced, the connecting webs can be attached adjacent to the areas which are to be kept free for the profile openings. Within the freely held areas between the connecting webs the profile openings are easily introduced if necessary.

The strength of the retaining plate and thus the stability of the construction can be further improved by a suitable material selection and / or dimensioning of the wall thickness. The holding plate can be made, for example, from high-strength GFK or CFRP composite materials. Other materials may be used, such as steel or aluminum sheets, the wall thickness is interpreted in terms of the required stability accordingly.

The profile openings may have slots for the formation of particular floor rails and partition wall rails. In the slots guide bolts or T-sliding blocks of loading beams or suitable carriages can be used. The slots correspond in their function floor or partition wall rails.

Furthermore, the profile openings can be designed to receive locking rods. For this purpose, the profile openings may have a round or oval cross-section for receiving spring-loaded axially movable retaining bolts of the locking rods.

In a further embodiment, the profile openings are designed to receive lashing strap fastenings. In this case, the profile openings may be provided as short slots in the retaining plate, are used in the appropriate bracket, which are connected to the lashing straps.

In a particularly preferred embodiment, channel openings are provided in the retaining plate for connection to an air conditioning system. The channel openings can be designed both as inlet and outlet openings and allow safe flushing of the transport goods arranged in the structure. This ensures a good and as complete as possible air conditioning of the interior of the structure.

Alternatively, the air conditioning of the structure can take place in that the air conditioning air is not introduced into the interior, but is used to actively cool the functional chamber. This means that there is no air connection between the function chamber and the interior, so no channel openings are arranged in the holding plate. Rather, the functional chamber is connected to the air conditioning system such that the air conditioning air flows through the entire functional chamber and thus provides improved heat dissipation in the region of the component. For this purpose, the function chamber is integrated into the climatic air circulation of the air conditioning system.

This applies to the design of the component as a wall element, floor element and roof element, so that the entire wall of the structure is actively cooled.

Furthermore, it can be provided that a circulating air chamber with supply channels is arranged on an outer side of the functional chamber, which is connectable or connected to the interior of the commercial vehicle body. With the recirculation chamber is an additional level for the air supply available, whereby a particularly effective air conditioning of the structure is made possible with large air currents.

An improvement in the insulation of the structure can be achieved in that the circulating air chamber has insulating elements between the supply channels.

The supply channels can be optionally closed to set different temperature ranges. This embodiment is particularly suitable for structures whose useful space can be changed, for example, by drawing in a partition, since different temperature ranges can be set by the optional closeability of the supply channels in the various utility rooms. In this way, a particularly energy-efficient air conditioning of the structure is possible.

The insulation of the structure can be further improved by providing an isolation chamber on an outer side of the circulating air chamber.

Furthermore, a commercial vehicle is claimed with a wall element or roof element according to the invention.

The inventive method for producing a wall element or roof element for a commercial vehicle body based on the fact that at least one functional chamber is made with a holding plate which limits the interior of the commercial vehicle body in use. If necessary profile openings are introduced into the holding plate for receiving fasteners for installations. This implies that the holding plate is sufficiently stable to absorb the forces that are introduced by the internals on the profile openings in the holding plate.

Furthermore, a circulation system for a commercial vehicle structure is disclosed, which comprises at least one loading beam with a plurality of air openings arranged along the longitudinal axis of the loading beam.

With the additionally disclosed air circulation system, the problem is solved that in conventional air circulation systems, such as from the DE 100 29 355 A1 known, the circulating air is introduced via the side walls in the interior of the commercial vehicle body, so that the arranged in the middle of the interior of transport goods are less washed around, as arranged on the side walls of transport goods.

The circulating air system described here, however, allows distributed over the entire width of the structure distributed supply of circulating air, so that all transport goods located in the interior are evenly washed and cooled.

This advantage is achieved in that a plurality of air openings arranged along the longitudinal axis of the loading beam are provided in the loading bar or in all loading bars. In use, each loading bar is connected to the recirculation system. This can be done by connecting the loading bar to a supply channel which is arranged in a side wall of the commercial vehicle body. Other feeding possibilities of the circulating air to the loading bar, for example by hoses, are possible.

The advantage of the circulating air system disclosed here is that the loading bar acts as an air distributor, so that a uniform cooling of all transport goods in the structure is achieved.

The circulating air system is disclosed independently of the component, specifically the wall element and / or roof element, with the functional chamber. A combination of the functional chamber with the recirculation system is also possible.

The invention will be described below with reference to embodiments with reference to the accompanying drawings with further details.

12 an interior perspective view of a commercial vehicle body with a front wall and two side walls, for reasons of clarity to represent the circulating air chamber, the function chamber is omitted.

In the 1 . 2a and 2 B is a cross section through a component according to an embodiment of the invention shown. This component, which is a wall element or roof element according to the invention, is used for the production of commercial vehicle superstructures, in particular insulated box bodies.

In general, the invention includes all possible structures, especially box bodies on motor vehicles, trailers with drawbar and semitrailers. Another area of application of the invention are exchangeable cases and transport containers.

The device according to the 1 . 2a and 2 B comprises three chambers, namely a functional chamber 13 , a circulating air chamber 23 as well as an isolation chamber 27 , A different number of chambers is possible, wherein for the load securing the function chamber 13 is mandatory. For example, could on the recirculation chamber 23 be waived if a cooling of the goods in the commercial vehicle body is not required. The same applies to the isolation chamber 27 ,

The functional chamber 13 is arranged on the inside of the component, that is to say on the side facing the interior of the assembly, and comprises a stable holding plate 15 that the interior 14 (S. 7 ) limited. The holding plate may also be composed of several part holding plates in a modular manner, wherein the individual part holding plates are connected by a known per se clip system.

The stability of the functional chamber 13 , in particular the holding plate 15 is sufficiently large to ensure the storage of internals including the transport goods arranged thereon. As in particular in 2 B to recognize, therefore, is the holding plate 15 through connecting bridges 18 reinforced, extending between the two insides 19 extend the functional chamber and connect them. In the 2a . 2 B is only one of the two insides 19 to recognize.

The connecting bridges 18 are designed as angle profiles and have three plane-parallel legs 18a . 18b . 18c on, with the middle leg 18b at the holding plate 15 opposite arranged inside 19 the functional chamber 13 is applied. The two outer thighs 18a . 18c lie against the retaining plate. The thigh 18a . 18b . 18c are with the respective walls of the functional chamber 13 firmly connected.

Another embodiment of the connecting webs 18 is in 10 shown in which the middle leg 18b is interrupted, so that the angle-shaped and integrally formed connecting web 18 according to 2 B in 10 is formed in two parts. This allows the distance between the perpendicular to the mounting plate 15 arranged web parts are changed.

Another training of the connecting bridges 18 is possible, for example as a double-T-carrier or -Stege.

Alternatively to reinforcement of the functional chamber 13 or holding plate 15 through connecting bridges 18 can also change the wall thickness of the retaining plate 15 be increased to the strength of the retaining plate 15 to improve. An improvement in the strength of the retaining plate 15 can also be achieved by a suitable selection of materials. Usually, the holding plate 15 designed as a steel or aluminum sheet with a suitable wall thickness. In addition, it is also possible to use modern materials, such as GRP / CFRP composites, which have excellent strength properties at a low specific gravity. The strength of the retaining plate 15 depends on the force to be initiated. Since this force depends substantially on the weight of the cargo to be transported, it is at the discretion of the skilled person, the stability of the functional chamber 13 , in particular the holding plate 15 sufficiently interpreted, wherein, as explained above, the use of connecting webs 18 to reinforce the functional chamber 13 is recommended.

In the 1 . 2a . 2 B It can also be seen that on the outside 22 the functional chamber 13 a convection chamber 23 is arranged. Furthermore, on the outside 26 the circulating air chamber 23 an isolation chamber 27 intended. Both the convection chamber 23 as well as the isolation chamber 27 each have connecting webs 28 on that both the individual chambers 23 . 27 strengthen as well as the entire structure of the component. Thus, the rigidity of the component is increased, so that even heavy goods can be easily transported or secured.

The component according to the invention can define a one-piece wall element or roof element. In this sense, the term "chamber" a corresponding planar structure understood, the longitudinal or vertical extent is considerably greater than the thickness of the component. It is also possible that the component forms only a part of a complete wall or roof, so that the wall of the structure is composed of several individual components in a modular manner.

In the 3 to 6 different embodiments are shown, with reference to which the various security systems are explained, which can be realized in the device, the illustrated embodiments, the use of the device as a side wall 10b affect.

In 3 is the unprocessed execution of the holding plate 15 shown. It can be seen that it is an inside smooth side wall on which no fastening means are provided. This embodiment of the invention differs from conventional commercial vehicle structures in that the retaining plate 15 is in principle suitable for absorbing forces which occur during charge transport or load securing. In conventional side walls or inner cover layers such a force is not possible directly into the wall, as this separate fasteners, such as floor rails or anchor rails are provided which absorb the introduced forces. The increased stability of the retaining plate 15 or the entire functional chamber 13 is through the already described connecting webs 18 ensures that the retaining plate 15 reinforced locally, especially in the area of forces to be deployed. Alternatively, the retaining plate can 15 differ by a corresponding dimensioning of the wall thickness or by a suitable choice of material in view of the increased strength of conventional side walls.

In 4 is shown in the retaining plate 15 profile openings 16 for mounting fasteners for installations 17 are introduced. At these profile openings 16 these are anchorages 16a , which are designed to receive locking bars. These anchors 16a are formed as circular openings, in the axially movable locking pins of the (not shown) locking rods are used. These bolts are acted upon by a spring force and can be withdrawn for disassembly or removal of the locking rods.

As further possible internals, which can be arranged transversely to the longitudinal direction of the structure, clothes racks are to be mentioned, which are anchored in a similar manner as the locking bars described above in matching profile openings in the holding plate 15 are introduced.

Furthermore, in 4 short slits 16b to recognize, can be used in the bracket or brackets for lashing straps in general.

The profile openings 16 . 16a . 16b according to 4 So act as horizontally arranged anchor rail and can at any height and any distance in the holding plate 15 introduced, milled according to the invention, be.

According to 5 are the profile openings 16 as vertically arranged slots 20 executed, which extend substantially over the entire inner height of the interior and are provided for guiding and storage of loading beams for a double-decker load. In the slots 20 are led (not shown) T-sliding blocks of the loading bars.

Next are in the retaining plate 15 Not shown detent openings provided, engage in the provided on the bar shoe of the loading beam pawls and thus lock the loading bar in the desired height. The latching openings (profile openings) are arranged at a certain distance and thus form a grid that allows a step-like height adjustment of the loading bars.

In the embodiment according to 6 are in addition to the slots 20 according to 5 channel openings 21 in the holding plate 15 intended, which allow an air connection between an air conditioning system and the loading bar ( 9 ). This embodiment is related to 9 described in more detail.

To reinforce the retaining plate 15 are the connecting bridges 18 the arrangement of profile openings 16 arranged or formed accordingly. For example, the connecting webs 18 in the case of floor loading ( 5 . 6 ) arranged perpendicular to the plate. The connecting bridges 18 for the load securing of standard pallets, roll containers, etc. are provided in standard heights, so that between these connecting webs 18 after introduction of the profile openings 16 Locking bar or lashing straps can be anchored. In this case, the connecting bridges 18 arranged horizontally.

For a flexible and at the same time very stable attachment or securing of cargo are the connecting webs 18 arranged in the form of a grid with horizontal and vertical grid lines, wherein the distance between each two subsequent vertical or horizontal grid lines substantially defines the minimum distance between two floor or anchor rails.

In the event that the device according to the invention is used as a roof element, can in the function chamber 13 further functional profiles, such as slots are incorporated, can accommodate the carriage for a sliding partition (not shown). The particular advantage of this is that with simultaneous floor loading the support beams can be raised to below the ceiling, without affecting the loading process and the air circulation.

In a further embodiment, not shown, thickening in the inner skin or the holding plate are for the transport of hanging meat in the standard distance thickening 15 provided the roof element, in which are incorporated for the assembly of Kragkonsolen of pipe runs thread. These threads are closed with a thin cover layer and can be easily opened if necessary.

In an analogous manner, as in connection with the side walls according to the 4 to 6 described, also the roof elements or floor elements may contain functional profiles, which in the holding plate 15 are introduced accordingly to receive vertical locking rods with locking pin.

Subsequently, the climate air control system based on the 7 to 12 described. This climate air guidance system can be used together with the functional chamber explained above.

The climatic air guidance system is in the circulating air chamber 23 accommodated. For the sake of better representability is in the 7 and 8th the functional chamber 13 omitted, around the rear air circulation chamber 23 to be able to recognize.

In the 7 . 8th are two wall elements 10 , in particular a front wall 10a and a side wall 10b as well as the floor element 11 shown. In the front wall 10a is a cooling unit 29 integrated with heat exchanger and blower. The front wall 10a is according to the patent application "Construction for a trailer of a truck and trailer of a truck" DE 10 2005 061 963 whose content is fully incorporated by reference into this application. The front wall 10a is accordingly thermally designed so that the insulation is given for the goods and the cooling of the cooling unit is guaranteed.

As in the 7 . 8th to recognize are in the front wall 10a supply channels 24a designed for climatic air, which is arranged vertically and with the cooling unit 29 are connected. In the supply channels 24a are channel openings 21 provided that the supply channels 24a with the interior 14 connect the commercial vehicle body. The canal openings 21 serve in this case as air inlet openings, sucked by the air under construction and the cooling unit 29 is transported. On the concrete formation of the channel openings in Einsaugbereich or in the air outlet area is in connection with 10 returned.

The integration of the supply channels 24a in the front wall 10a has the particular advantage that it can be dispensed with the required in the prior art air return profiles, in particular hat profiles. Since the hat profiles projecting into the cargo compartment are eliminated, the loading area is increased so that more standard pallets than previously possible can be placed in the cargo space.

Instead of below the cooling unit 29 arranged supply channels 24a can in the front wall 10a a storage space can be integrated, which serves for example for receiving tools. The return air is through appropriately arranged inlet openings in the top layer of the front wall 10a introduced into this storage space. The storage space opens into a collection hood, via which the return air to the cooling unit 29 is supplied.

The refrigeration unit 29 are two distribution channels 24b downstream, each in the front wall 10a are integrated. The two distribution channels 24b on both sides of the cooling unit 29 are provided, the conditioned air lead to the supply channels 24c in the side walls 10b as well as to the supply channels 24d in the roof element 12 ( 12 ). The in the roof element 12 provided supply channels 24d have openings opening into the cargo space 21 on, through which the climate air can flow into the hold. The climate air in the supply channels is thereby 24d transported to the end of construction (not shown).

The same applies to the climatic air in the side walls 10b passing through the horizontally arranged supply channels 24c is passed to the end of construction. The horizontal supply channels 24c are with the vertically arranged slots 20 or profile openings 16 connected for the double-decker loading, so that, as in 7 indicated by the inwardly curved arrows, the climatic air at these points in the interior 14 of commercial vehicle construction can flow. At the bottom of the inside functional chamber 13 are also channel openings 21 provided by the climatic air from the side wall 10b in the interior 14 can get. The air conditioning is in the 7 and 8th illustrated by arrows.

A particularly good rinsing of the goods to be transported is achieved in that, as in 9 shown, the climatic air from the side wall 10b in the stringers 17 is initiated. These are the stringers 17 with the channel openings 21 of the air conditioning control system according to 6 connected. The stringers 17 include further channel openings 30 through which the climate air into the interior 14 flows. The distribution of climate air in the interior 14 through the stringers 17 has the advantage that the climate air not only in the area of the side walls, so laterally from the outside into the interior 14 is initiated, but over the entire width of the interior 14 ,

Specifically, the channel openings 30 or louvers on a vertical side wall of the loading beam 17 or supporting beam 17 intended. It is understood that the channel openings 30 or the louvers on each free side surface of the support beam 17 can be arranged so that an unhindered leakage of air is made possible. In particular, it is also possible, the channel openings 30 or air slots at the bottom of the support beam 17 to arrange. As further in 9 to recognize, are several channel openings 30 or louvers along the longitudinal direction of the support beam 17 arranged. It is also conceivable to provide a continuous ventilation slot which extends in the longitudinal direction over the complete or at least approximately complete supporting beam. It is possible to use all the free side walls of the supporting beam 17 with channel openings 30 or louvers at the same time.

In 10 is good to see that the convection chamber 23 or in the circulating air chamber 23 arranged supply channels 24 with those in the function chamber 13 arranged channel openings 21 are connected. The same applies to 11 in which the connection between the chambers 13 and 23 indicated by corresponding arrows. The supply channel 24 the circulating air chamber 23 that with the canal opening 21 is connected, includes one as a spoiler 31 trained footbridge, which the climatic air to the canal opening 21 deflects, so that the climatic air with the least possible loss in the interior 14 can flow. The on the front wall 10a arranged inlet openings 21 can be designed accordingly.

For the application of the device as a side wall or front / rear wall element is that the horizontally extending supply channels 24 can be connected to one or more vertically extending air channels, through which the circulating air from the above the bottom arranged supply channels 24 down to the arranged in the region of the bottom channel openings 21 can be transported.

In the event that the circulating air is introduced only into the functional chamber and flows through it completely, it may further be provided that the vertically extending reinforcing webs or connecting webs allow a flow of air from top to bottom, for example in that the vertically arranged connecting webs at several points interrupted or formed as perforated plates.

Furthermore, it is possible between the individual supply channels 24 Isolation elements (not shown) to arrange, through which the insulation effect of the structure is improved overall.

When using a partition, the supply channels 24c in the sidewall 10b controlled closed, so that a second temperature range is created. The supply of conditioned air for the first temperature range then takes place exclusively via the roof supply, which is sufficient with a reduced internal volume for the desired cooling. The continuing air ducts or supply channels 24d in the roof element 11 are closed by locking units of the vertical partition (not shown).

In order to improve the cooling effect in the rear wall (not shown), further supply channels can be arranged in the rear wall door, which are arranged via the supply channels 24c in the sidewall 10b be fed. The same applies to an optional partition, in which supply ducts for the recirculation system are also integrated, for example those in the roof element 12 arranged supply channels 24d be fed. The same applies to the floor element 11 , In this way, a transport space enclosed on all sides is formed, the entire wall of which is actively cooled.

The external insulation by means of the isolation chamber 27 can by suitable insulating media, for. B. be carried out by foam or by vacuum chambers. The same applies to the insulating elements in the circulating air chamber between the supply channels 24 are arranged.

The aforementioned embodiments comprise modular components with insulation, air conditioning and a functional chamber for the attachment and securing of goods to be transported. The function chamber allows a multifunctional arrangement of the fasteners or fixtures in the holding plate 15 because the arrangement or the type of attachment by flexible introduction of profile openings 16 in the holding plate 15 is achieved by milling. The introduction of the profile openings can be made at the factory before assembling the structure. According to the invention, however, is advantageous that the introduction of the desired profile openings is possible later in the assembled structure.

The concept of the functional chamber thus leaves the usual procedure, commercial vehicle bodies according to the particular customer requirements with fasteners, such as floor rails or anchor rails to provide, but offers the advantage of a standardized component, concrete a wall element or a roof element to provide, by minor modifications (introduction of profile openings) can be adapted to the respective customer requirements.

The module structure of the device according to the invention also offers in the form of an independent aspect of the invention, the possibility that the circulating air chamber is used without the function chamber when a fastening and securing the charge is not required, but only an air conditioning. In this case, it would be sufficient, the device with the circulating air chamber 23 and optionally with an externally disposed isolation chamber 27 equip, wherein the inner wall of the circulating air chamber 23 the interior 14 limited. In the circulating air chamber 23 are supply channels 24 arranged for the conditioned air circulating through the duct openings in the circulating air chamber 23 with the interior 14 are connected. Alternatively, it can also affect the air connection between the recirculation chamber 23 and interior 14 be waived if only a cooling of the component without flushing the transported in the structure charge is desired. In this case, the circulating air flows through the complete circulating air chamber, which is integrated in the climatic air circulation.
