Description

The invention relates to a bracket for attachment to an outer surface of a roof, wall or floor element, wherein the console comprises a support portion which has a greater length than width and on which is provided for abutment against the respective outer surface bearing surface and wherein at least one mounting portion is provided on the support portion, on which acts in use a fastener via which the bracket is held on the outer surface.

Likewise, the invention relates to a compound of such a console with a roof, wall or floor element.

Finally, the invention also relates to a commercial vehicle for the transport of goods, comprising a structure with a roof, wall or floor element, with which a console of the type in question is connected.

The brackets of the type in question are arranged on the outside of the respective roof, wall or floor element, which faces the space bounded by the element in question. The roof, wall or floor elements are typically panels extending over a large area, as are required, for example, for constructing box bodies of commercial vehicles for the transport of temperature-sensitive goods. In such a box bodies, the cargo is conveyed hanging, for example, via a console connected to the roof panel on the ceiling of the box body. For this purpose, several brackets can be connected at regular intervals with the ceiling, which together carry a support rod to which the cargo is hung by means of suitable hooks.

The ceiling, wall or floor elements comprise in addition to a conclusion to the space limited by the respective element forming, for example, steel or an Al-material existing cover layer usually further layers, including a so-called insulating layer, for example, a foamed, thermally insulating material exists and is arranged at the back of the cover layer facing away from the space in question. The cover layer itself can also be constructed in several layers in order to give it the respectively required properties, such as high buckling stiffness, optimized tightness and the like.

In order to sufficiently reinforce the generally thin and therefore less resilient cover layer in the areas in which the load of the cargo to be transported is struck over the brackets, profiles which have the required stiffening of the roof, wall Take over or soil element in the loaded area, and provided reinforcing elements over which the intended for the connection of the console with the respective roof, wall or floor element fastener is held on the element in question.

A problem arises from the fact that in the production of the respective roof, wall or floor element, the foam of the insulating layer penetrates as a result of the forces resulting from its expansion in the joining zones between the cover layer and the profiles or reinforcing elements. The cover layer is then no longer close to the respective profile or the respective reinforcing element, but is supported by a, albeit thin, yet resilient cushion of insulating foam against the relevant profile or reinforcing element. When mounting the console to the respective roof, wall or floor element, the insulating foam is indeed compressed, but remains present. Thus, for example, as a result of further compression or displacement of the foam present in the respective joining zone, which may be caused by the frequent high loads encountered in use, the compound may "settle" in use Thus, the joint gap between the contact surface of the console and the outer surface widened, where the console is applied. This leads to a certain mobility of the console. This can in particular when the console is unloaded, lead to rattling noises and endanger the secure hold of the console to the respective roof, wall or ceiling element in extreme cases.

In a proven in constructions for commercial vehicles embodiment of a console of the type described above, this problem is eliminated in that each console is attached with two screws serving as fastening means to the respective roof, wall or floor element. In the event that one of the screw fastenings comes to rest, the other screw still holds the console firmly to the respective element.

Against the background of the above-described prior art, the object of the invention to provide a console in which an attachment to the respective roof, wall or floor element with minimal effort is possible and at the same settling phenomena are compensated.

Likewise, a connection between a roof, wall or floor element and a console should be created, in which even, when the connection is made, the width of the joint gap is minimized.

Finally, a commercial vehicle should be mentioned with a structure in which with minimal effort loosening the connection between a console and a roof, wall or floor element of the structure is safely avoided.

To solve this problem with respect to the console of the type mentioned, the invention proposes to equip such a console with the features mentioned in claim 1.

To solve this problem with respect to the compound, the invention proposes a compound formed according to claim 11.

To achieve the object with respect to a commercial vehicle for the transport of goods with a structure which has a roof, wall or floor element with an exterior bounded by the structure of the cargo space, the solution of the above object according to the invention is that an inventive Console is held by means of a compound according to the invention.

A bracket according to the invention for attachment to an outer surface of a roof, wall or floor element accordingly comprises, in accordance with the prior art mentioned above, a support section which has a greater length than width and on which a contact surface provided for abutment against the respective outer surface is formed is, wherein on the support portion at least one mounting portion is provided, acts on the in use a fastener over which the console is held on the outer surface.

According to the invention, the support section is now elastically yielding at least in a spring section extending over its length in the manner of a leaf spring against a compressive force acting against the contact surface and is shaped such that the spring section releases its relaxed condition when mounted on the outer surface during assembly on the outer surface is brought into a tense state in which he elastically yielding a compressive force against the outer surface.

In a console according to the invention thus on the support portion a resiliently elastic region is formed, which is stretched during assembly of the console on the respective outer surface of the roof, wall or floor element by an elastic deformation so that it is an elastically resilient, against the contact surface directed contact force exerts on the roof, wall or floor element to which the console is attached. The shape of the support portion is chosen so that the support portion initially comes, for example, only with two mutually spaced apart in the longitudinal direction of the support portion areas for mounting on the outer surface of the respective roof, wall or floor element during assembly of the console. When tightening the fastener then the spring portion of the support portion is elastically deformed until the contact surface rests flat close to the outside of the roof, wall or floor element. If the outside of the roof, wall or floor element sinks in, then the elastically prestressed spring section pushes in and the contact surface of the console maintains its tight contact with the outer surface. The console thus still retains its firm seat on the outer surface, when the connection of the console with the respective roof, wall or floor element sets. The danger that the connection loosens or rattling noises in the area of this connection is thus safely eliminated.

The particular advantage of the invention consists in accomplishing a secure connection between it and the respective roof, wall or floor element with only a single fastener with the inventively provided at least partially elastic support of the console. Typically, this fastener will be a screw or the like which acts with its screw head against a face opposite the abutment surface on the support portion.

For this purpose, the attachment region of the console can be formed by a through opening formed in the support section and the region of the support section surrounding the passage opening, in which a screw provided as a fastening means is supported with its screw head in use.

In principle, it is conceivable that the support portion is formed overall as a spring portion in the manner of a leaf spring and, for example, is bent so that its contact surface has uneven console evenly curved, in the side view arcuate course. However, a particularly high load-bearing capacity of the bracket can be ensured by the fact that the support section has a stable support section to which the spring section is connected. "Stable" means that the support section during assembly of the console maintains its shape, while the spring section is elastically deformed. Again, it proves to be advantageous in terms of mountability and effect when viewed in its longitudinal direction, the spring portion has a uniformly curved course when not mounted console.

The security of the attachment can thereby be optimized in that the fastening region is arranged between the support section and the spring section. Optimally, the fastening region is assigned to the support section for this purpose, that is, it is located in an equally stable region of the support section.

In order to couple a cargo or the like in a simple manner to the console, the console according to the invention as in the prior art may comprise a holder portion which is integrally formed on the side remote from the contact surface of the support portion. If such is present, the holder portion is expediently formed on the support portion. The holder portion may be formed in an equally known L-shape, with its one leg of the contact surface pioneering the support portion is formed, while the angle arranged to the first leg second leg of the holder portion with its free end facing in the direction also has the spring portion of the support portion with its free end.

In principle, all materials are suitable for the manufacture of a console according to the invention, on the one hand sufficient resilience and on the other hand can be shaped so that they can form a spring portion of the console in the context of the invention. Particularly inexpensive and at the same time functionally optimized, a console according to the invention can then be produced if it is manufactured in one piece from a metal material, in particular a light metal material, such as an Al material.

In accordance with the above explanations, a connection according to the invention between a roof, wall or floor element and a console according to the invention rests with its contact surface on the outer surface of the roof, wall or floor element and by means of an acting against its mounting area and on the roof. , Wall or floor element is held fixed fastener, characterized in that the spring portion of the support portion of the bracket exerts an elastic compressive force on the outer surface as a result of an elastic tension.

In this case, the invention proves to be particularly effective when the outer surface of the roof, wall or floor element is flat and the console rests flush with its contact surface flush with the outer surface. It is also conceivable, however, any other shape of the coming together in the compound in contact surfaces of the console and roof, wall or floor element, as long as it is ensured that the spring portion of the console in the course of assembly of the connection is braced so that he in the Connection finished assembled state exerts a compressive force on the outside of the roof, wall or floor element.

Ideally, the compound of the invention for the connection of a console according to the invention to a roof, wall or floor element comprising a cover layer of a solid material and an insulating layer, which is formed of a foam, which faces away from the outside back of the Cover layer is foamed, wherein at least one of the foam of the insulating layer surrounded reinforcing element is arranged on the back of the cover layer, which forms an abutment for the fastening element, which holds the console to the roof, wall or floor element. The reinforcing element can be a profile which gives the roof, wall or floor element in the region of the connection to the console such a high load-bearing capacity that the forces introduced via the console into the roof, wall or floor element are safe can be taken and endured permanently. The reinforcing element may additionally or alternatively also be a seated in the insulating screw, in which a screw for fixing the console can be screwed.

The invention will be explained in more detail with reference to a drawing illustrating an exemplary embodiment. Each show schematically:

1 a connection between a bracket and a roof element in a partially cutaway perspective view from below;

2 a console in a side view in the unstressed (solid line) and strained (dashed line) state;

3 a section of the ceiling element with attached console in a cross section.

The one-piece, for example, made of a light metal material console 1 is in a connection 2 on one side 3 a ceiling element 4 attached.

The ceiling element 4 is part of a construction not further shown here for a commercial vehicle, with the temperature-sensitive goods on the ceiling element 4 is transported hanging.

The ceiling element 4 includes one of the console 1 assigned cover layer 5 , on the outside 3 the console 1 is attached. The top layer 5 also indicates the outside 3 opposite side of the top layer 5 a back 7 on, to which a thermally insulating foam is foamed, to the insulating layer 8th of the ceiling element 4 to build. At her the top layer 5 opposite side is the insulating layer 8th through another cover layer 9 covered, like the top layer 5 , consists of a thin sheet steel.

The cast in one piece from an aluminum material or extruded console 1 has a support section 10 on, which has an elongated basic shape with a length L which is substantially greater than the width B of the support portion 10 ,

The supporting section 10 is functionally divided into a support section 11 and one to the support section 11 molded spring section 12 ,

Between the spring section 12 and the support section 11 sits a mounting area 13 the console 1 , which is a continuation of the support section 11 forms and approximately in the middle between the support section 11 and the spring section 12 is arranged.

The stable support section 11 exists like the attachment area 13 made of solid material and has a compact shape, which gives it a lasting dimensional stability even under the high loads acting in practice.

On one side of the support section 10 is a contact surface 14 trained with the console ready assembled 1 is flat and over the entire length L of the support section 10 extends.

In the attachment area 13 is a passage opening 15 molded, that of the contact surface 14 opposite side of the mounting area 13 to the contact surface 14 leads. The longitudinal axis of the passage opening 15 is essentially perpendicular to the contact surface 14 aligned.

At the of the contact surface 14 opposite side of the support section 11 is a holder section 16 formed. The holder section 16 has an L-shape and stands with its first leg in the mounting position of the console 1 from the support section 11 down, whereas its second leg with its free end facing in the same direction as the free end of the spring portion 12 , On the second leg is in a conventional manner a support tube 17 on, to which the goods to be transported, for example by means of a hook 18 can be coupled.

On the first leg of the holder portion 16 the console 1 is additionally a locking element 19 slidably mounted, resulting from a retracted waiting position in which the hook 18 along the support tube 17 can be moved into an extended locking position can be moved, in which the locking element 19 in the sense of a stop, a longitudinal movement of the hook 18 on the support tube 17 prevented.

The spring section 12 is much thinner dimensioned than the support section 11 and is in the manner of a tongue laterally from the attachment area 13 from. As a result of this dimensioning and shaping behaves the spring section 12 at a perpendicular to the contact surface 14 aligned direction to a certain extent resiliently. Affects a compressive force on the area 20 the contact surface 14 extending over the spring section 12 extends, so the spring section 12 thus in the manner of a leaf spring, with its one narrow side in the attachment area 13 is clamped elastically yielding to this load, wherein the relevant load counteracting resilient reaction force is formed.

This effect is at the console 1 reinforced by the fact that the spring section 12 when the console 1 in the relaxed, unassembled state (indicated in 2 through the console shown as a solid line), viewed in its longitudinal direction LR starting from the mounting area 13 bent so that it is viewed in side view ( 2 ), describes an arc. Alternatively, the spring section 12 in terms of the attachment area 13 be aligned at an angle, so that, in side view of the console 1 considered ( 2 ), which is on the support section 11 attributable area 21 the contact surface 14 with the on the spring section 12 attributable area 20 the contact surface 14 includes an angle that is less than 180 °.

When mounting the console 1 becomes the console 1 with its contact surface 14 to the outside 3 of the ceiling element 4 stated. It is in the ceiling element 4 a passage opening 22 molded, in the area at the back 7 the top layer 5 a stiffening profile 23 is glued on. The stiffening profile 23 has an alignment with the passage opening 22 aligned cutout in which a reinforcing element designed in the manner of an internally threaded screw sleeve 24 sitting. The reinforcing element 24 has a circumferential collar, with which it is on the cover layer 5 opposite side of the stiffening profile 23 is supported.

In still unstressed, but on the outer surface 3 attached state touches the contact surface 14 the console 1 due to the still bent or angled orientation of the spring section in this state 12 the outer surface 14 only with the free ends of their spring section 12 and their support section 11 , Will now be the console 1 by means of a serving as a fastener, with its threaded shaft through the through holes 15 and 22 pushed and into the reinforcing element 24 screwed in screw 25 against the outside 3 of the ceiling element 4 pressed, so deforms the spring section 12 elastic until the contact surface 14 as flat surface flat close to the outside 3 of the ceiling element 4 is applied. The shape of the console 1 in the fully assembled, strained state is in 2 indicated by a dashed line.

If it occurs during assembly or later use in the area created in the above-described manner connection 2 between the cover element 4 and the console 1 to settling, ie a slight yielding of the top layer 5 in a direction perpendicular to the contact surface 14 the console 1 aligned direction, so remains the spring section 12 due to its resilient elastic tension still in close contact with the outside 3 of the ceiling element 4 and thus provides the stable hold of the console 1 on the ceiling element 4 even then sure if the console 1 only with the single fastener, namely the screw 25 , on the ceiling element 4 is attached.

For example, settling may occur because of the attachment of the stiffening profile 23 at the back 7 used adhesive yields or insulating foam of the insulating layer 8th in the joining zones between the stiffening profile 23 and the top layer 5 or between the reinforcing element 24 and the profile 23 has passed, in consequence of the screw 25 applied force is compressed.
