Description

The invention relates to a component for attachment to flat Structures such as sheets, panels or the like.

Such a component is used, for example, in the motor vehicle technology for noise reduction and / or for stiffening the surface structure used. The flat structures are with Vehicle in particular bonnet, trunk lid, roof, Parcel shelf or the like. These are each relatively large cheeky and thin-walled. The component is on an inside that means on one opposite of the outer visible surface Side, attached to the flat structure.

To increase the rigidity of the roof of a motor vehicle Ges forming roof sheet is already known, a normal Cardboard on the inside of the roof facing the passenger compartment stick on the sheet. Such a box is known to be formed by two flat paper webs, between which sand a wavy profile made of paper is also arranged. This makes the box both relatively stiff when loaded in Normal direction as well as relatively stiff in the box plane.

A disadvantage of the carton has been found to be that already during manual attachment to the roof panel or during exercises a normal force for irreversible bending of the carton Kink lines in the top and bottom and deformations of the wel lenprofile occur. These kink lines affect the Stei ability of the carton and its appearance.

The invention is therefore based on the object of a component Attach to flat structures to provide that easy is manageable and through which in addition to noise insulation the rigidity of the flat structure in a simple manner and is specifically increased.  

This object is achieved in that the component as a reinforcement fungboard with a two-dimensional arrangement of protrusions and recesses for absorbing tensile forces in the panel plane and with Be arranged at least on one side on the board planking is formed.

The two-dimensional arrangement of protrusions and depressions serves in particular to stiffen the flat structure, since this arrangement stiffened the component in the board level. Simultaneously The component can work in the normal direction, i.e. perpendicular to Blackboard level to be relatively flexible, which, for example, a good adaptation to curved flat structures is given. The arrangement of protrusions and depressions is varied tiger both in terms of the geometric shape of Vor jump and deepen, their relative arrangement, their Hö he or depths or the like can be varied. To do that Component specifically in its rigidity or in its ability change to absorb tensile forces in the board level, the stiffening panel has at least one side on the Ta arranged paneling. This can be, for example a lower or upper flat side of the stiffening panel be educated. The planking can be strip-shaped and only extend along certain directions in the plane of the board. Next individual planking strips can be parallel to each other and arranged in the same direction or in strip groups be at a certain angle to each other. For example, a group of strips can be perpendicular to egg ner further strip group of the planking can be arranged.

The projections of the stiffening panel can also be used bring to the flat structure to be used. Depending on the mate rial of the component can be connected to the flat structure structure by gluing, welding or the like. When gluing you can glue on a selection of protrusions be applied so that the connection of component and Structure both in terms of position and in terms of Size of the connection area between the board and the structure can be determined beforehand.  

The size of the connection area can thus be selected the that the projections to be connected a greater height than have the other projections. That way, both the depressions as well as those not used for the connection NEN projections spaced from the flat structure.

Depending on the formation of the projections, these are with the structure punctiform or over one of the flat structure connected flat planar area. The geometri The shape of the investment areas is almost arbitrary angular, round, teardrop-shaped, oval, dumbbell-shaped, fish-shaped can have mige or other cross sections. In this To it is beneficial if at least the investment areas of the projections used for the connection flush are arranged so that they are overall on the flat structure issue.

The planking can be made in one piece with the stiffening panel be put. The planking can also be used, as already mentioned above believes to be formed from individual planking strips that subsequently and to increase the rigidity of the Stiffening panel are attached to this. Another The exemplary embodiment is the cladding as a separate cladding training board trained. This overlaps the stiffening panel for example partially and is in the overlap area with this connected. The board can also be compared to Stiffening panel should be made smaller so that it is only egg part of the stiffening panel and covered with the is connected.

The planking can be made of a flat material with essentially Chen flat surfaces are formed, one of these flat sides of the stiffening panel and connected to it that is. The Beplan can be used to further increase the rigidity kung advantageously at least one-sided two-dim Sional arrangement of projections and depressions. These can be compared to the protrusions and depressions the stiffening plate has a different geometric shape, under  different highs or lows and another two have dimensional arrangement.

To produce a component with a sandwich-like structure, is it is convenient if there are idles on both sides of the stiffening panel table boards are arranged. Such a sandwich Like structure is also by arranging various tarpaulins Produce kung boards on both sides of the stiffening board bar.

To the connection between the cladding panel and the stiffening panel to simplify the field and to ensure an accurate relative position To be able to do without each other, it is in this together mangle is an advantage if the paneling is on a level Flat side of the stiffening panel is arranged. The connection between flat sheets can be done by creating flat flat sides probably from planking board as well as from stiffening board as well in another advantageous embodiment Connection of at least a selection of projections of the Beplan kung board with the stiffening board. Assigns the ver stiffening panel on the flat facing the paneling panel If there are protrusions and recesses on the side, this can correspond de Connection also by connecting protrusions of both Ta fields.

The arrangement of depressions and projections can be depending on the Be may be done, it may be cheap, stiffening board and / or cladding panel on both flat sides with one two-dimensional arrangement of protrusions and depressions to train. As already said, there are multiple variations regarding their training and arrangement possible.

In a simple embodiment, together protrusions and depressions on one flat side complementary depressions and protrusions on the other Flat side formed. In this way, the boards at for example with all projections and depressions in one area beitsgang manufactured by appropriate shaping the. It should be noted that the stiffening panel and  Cladding panel also in one step and in one piece can be manufactured.

In a simple embodiment are stiffening panels and cladding panel are identical. That means that at de sheets can be taken from a material supply and For example, a planking board in one stiffening tape already attached to the flat structure fel can be attached. This then proves to be expedient ßig if the rigidity of the flat structure due to anbrin only the stiffening panel cannot be increased sufficiently could. The cuts of the stiffening board and / or tarpaulin Kungstafel can have the same or different dimensions exhibit.

The relative arrangement of the cladding panel and the stiffening panel fel can be done in such a way that the respective Projections are interconnected. With an arrangement al ternative are the projections of the planking panel in the vertical the stiffening panel.

Are projections and / or depressions of both panels with each of the same geometric shape result in arrangement directions of the projections and depressions isotropic eigen create. Should the properties of the panels along we change at least one direction in the board level can in ent speaking the geometric shapes of the projections and / or depressions and their height or depth can be varied. For example, the investment areas of Projections become smaller or larger, the number of projections ge can increase or decrease or the like, wherein a variation along a direction continuously or dis can be done continuously.

To connect with the flat structure, both Ver stiffening board as well as the planking board who the, these each at least partially on the flat Structure and are connected to it. The Connection, as already mentioned above, via a selection  the projections or by means of all the projections or via one flat flat side of a board.

In a simple embodiment are protrusions and / or depressions each with the same geometric shape and / or trained the same height or depth det. A particularly simple arrangement of projections and / or Deepening results in a row-by-column approach order, creating a network-like two-dimensional arrangement given is.

A simple embodiment for projections and recesses gene with, for example, complementary training of upper and lower flat side of the plates is given by the fact that the front jump a flat top egg on the top flat side of the board te and are surrounded by groove-shaped depressions. The Grooves can have, for example, a U-shaped cross section a right-angled or rounded transition between the U-bridge and associated U-legs. The grooves in the top Flat side form correspond to the lower flat side de projections and the projections on the upper flat side bil the depressions in an analogous manner on the lower flat side.

The geometric shapes of protrusions and / or depressions and / or their height or depth along little at least one direction in the plane of the stiffening plate and / or planking board can change to the own properties, such as rigidity, depending on the direction shape.

An inexpensive material for the production of the component is art fabric, the plastic directly or with an embedded Fibrous material, filler or the like in the corresponding Form of stiffening or cladding panel are brought can. Compared to cardboard, such a material is longer durable and does not rot or mold under moisture influence of temperature or heat. The boards are directly with certain Dimensions or can also be produced as running rolls, the sheets from the roll goods with the required dimensions  can be cut out. By adding different fiber or Fillers can vary the thermal expansion of the panels and, for example, the thermal expansion of the flä structure to be adapted. To improve the optical Appearance of the panels can be at least one-sided Show lamination. The lamination can also be used between Ver stiffening and planking panel can be attached.

As a rule, stiffening and cladding panels are made of fabric connected with each other. The connection can be made by se apply an adhesive or by heat follow, in the latter case the connection of both panels before attaching to the flat structure, for example in a appropriately trained press can take place.

Show planking and stiffening board at least on theirs mutually facing flat sides protrusions and depressions , as already stated, these can be closed exactly be assigned to each other. In this case, each lies Projections or depressions of both panels against about. It is also possible to have protrusions and / or depressions to arrange both panels offset to one another or to a gap. in the the latter case there is a protrusion of the stiffening ta against a corresponding recess in the paneling about.

In this case, the connection of both panels can be along Lines of contact of the protrusions and depressions, rel wise with different sized projections and Wells, by means of the Be rich of the protrusions are made.

In the simplest case, the stiffening panel and the planking panel are shown same dimensions and the two-dimensional network protrusions and / or depressions form a two-dimen- sion sional closed way. That means that everyone can be sweet lead or deepening along a path and ent long further protrusions or recesses to each another lead or depression. Be there  again noted that the protrusions on the top Flat side of a chalkboard the depressions on the lower flat side and vice versa.

To attach to the flat structure in this together menhang, for example, the crossing points of the two dimes sional network-like arrangement of the projections serve.

For example, the component for air flow and thus for loading Ventilation and / or cooling of a motor vehicle in the area of To be able to use flat structure, it proves in particular another as an advantage if projections and / or depressions of Stiffening board and planking board between them Form openings that are open at their ends. Thereby these bushings can be used to guide air the, with a corresponding at the ends of the bushings Air can be supplied and / or discharged.

Corresponding to Fig. 5, the thickness of Beplan can of course kung panels 8 may be different. Likewise, the thickness of one or both cladding panels can increase or decrease from left to right in FIG. 6.

The stiffening panel 7 has complementary upper and lower flat sides, depth 19 of the recesses 4 on the upper flat side and height 18 of the projections 5 on the upper flat side along the section being constant. It should be noted once again that depressions 4 and before projections 5 form complementary projections or depressions on the underside of the stiffening panel 7 in FIG. 6, see also FIG. 4.

Depth or height of the corresponding depressions and projections are the same in both panels 7 , 8 , so that overall the contact surface formed essentially by lower flat side 14 and upper flat side 13 of stiffening plate 7 and cladding plate 8 forms a plane of symmetry for that shown in FIG. 7 Component forms.

FIG. 8 shows a seventh exemplary embodiment analogous to FIG. 2. Stiffening plate 7 and cladding plate 8 are again of the same design. However, in contrast to FIG. 7, both plates are connected to one another with their flat flat sides, the alternating arrangement of projections 4 , 10 and depressions 5 , 11 being formed on opposite flat sides of both panels. Furthermore, the projections 4 of the stiffening board 7 are offset from the projections 10 of the paneling board 8 . Of course, the degree of displacement can be arbitrary, so that for example a projection 10 of the cladding plate 8 in the union union at any point between two adjacent jumps 4 of the stiffening plate 7 can be arranged.

Fig. 9 shows a single stiffening or Be plankung 8 with corresponding projections 4 , 10 and Ver recesses 5 , 11th The panel is designed like the stiffening panel 7 according to FIG. 7. Such a panel can, for example, be additionally arranged on the component according to FIG. 8, in that the depressions 5 , 11 are plugged onto corresponding projections 4 , 10 of one of the panels 7 , 8 shown there. The ent speaking projections 4 , 10 of FIG. 9 lie on the corresponding recesses 5 or 11 of FIG. 8. Analogously, the panel 7 , 8 according to FIG. 9 can also be arranged, for example, on the lower flat side of the paneling panel 8 according to FIG. 10.

Corresponding projections 4 or depressions 5 are arranged opposite to recesses 11 and projections 10 of the loading plan 8 . As a result, approximately tunnel-shaped bushings 25 are formed between the stiffening and planking panels 7 , 8 .

In FIG. 11, stiffening panel 7 and cladding panel 8 are designed analogously to stiffening panel 7 according to FIG. 6. Both panels are in the cutting direction of FIG. 11 to each other so ver arranged sets that projections 4, 10 or Vertie levies 5, 11 are plugged into one another in the plug-sixteenth The offset of the two panels is at least so large that the projections or depressions of both panels 7 , 8 can be inserted into one another by friction. In general, the panel 8 is offset relative to the stiffening panel 7 to egg NEN projection or a recess, so that just a projection of the panel 8 from un th into a corresponding next larger projection of the stiffening panel 7 can be inserted.

FIG. 12 shows a tenth exemplary embodiment analogous to FIG. 2. The stiffening panel 7 is formed analogously to the stiffening panel 7 according to FIG. 5. The board 8 essentially corresponds to the board 8 according to FIG. 7, the height 20 of the projections 10 decreasing from left to right in FIG. 12. In an analogous manner, the depth 21 of the recesses 11 of the cladding plate 8 decreases from left to right. Furthermore, the depressions 11 of the cladding panel 8 are arranged approximately in the center of projections 4 on the lower flat side of the stiffening panel 7 . In this way, bushings 25 are formed between projections 10 and depressions 5 or depressions 11 and projections 4 of the respective panels 7 , 8 .

FIG. 13 shows an eleventh embodiment analogous to FIG. 2. The stiffening panel 7 corresponds to that shown in FIG. 5 and the cladding plate 8 corresponds to the stiffening panel 7 shown in FIG. 8.

The cladding panel 8 is designed analogously to the panel according to FIG. 9. Wells in the paneling 8 are arranged at the corresponding locations of the wells of the stiffening board 7 . In the twelfth embodiment, a lamination 24 is applied to the top of the panel 8 . A corresponding lamination can be arranged at least on one side on one of the panels 7 or 8 and on both panels 7 , 8 in each of the exemplary embodiments described.

Fig. 15 shows a thirteenth embodiment analogous to Fig. 2. Stiffening panel 7 and cladding panel 8 are essentially the same as Fig. 8, but there is no offset between projections or recesses. There is a further paneling 8 angeord net, so that the first, provided with projections formed on its lower flat side paneling 8 is sandwiched between the stiffening panel 7 and the second side just formed second paneling 8 .

It goes without saying that the second cladding panel 8 can also be used in each of the preceding exemplary embodiments and can also be designed corresponding to the stiffening or cladding panels 7 , 8 shown .

Fig. 16 shows a detail of a plan view of a component according to the inven tion, with various geometric shapes for projections 4 , 10 and depressions 5 , 11 of the stiffening or cladding panel 7 , 8 being arranged along the longitudinal direction 22 . A first type of protrusions has a square and a second type of protrusions a three corner cross section. Two directly adjacent triangular projections are rotated by 180 ° to each other.

While the arrangement of projections along a row, see FIG. 1, is shown in FIG. 16, other geometric shapes or columns can be used for the projections in further rows. Accordingly, such an arrangement of different projections can be used for each of the different exemplary embodiments according to FIGS. 2 to 15.

In Figs. 17 to 25, a choice of exporting is approximately examples of two-dimensional arrays of protrusions and recesses shown, the page on the lower and upper flat of the inventive component 1 and auctioning Fung panel 7 and / or are formed Beplankungstafel. 8 The cutouts shown can be parts of the lower and / or upper flat side of the panels. As already stated, the lower and upper flat sides can each be complementary to one another. In the following, the same reference numerals denote the same parts of the panels.

In FIG. 17, the two-dimensional arrangement 3 , 9 for the panels 7 , 8 comprises square projections 4 , 10 and depressions 5 , 11 each surrounding them. In the following, the various exemplary embodiments are explained only for stiffening panels 7 , it being understood that corresponding arrangements can also be selected for the cladding panels.

According to FIG. 17, the projections in rows and columns are arranged, in which FIG. 2 is a section along the line II-II. The further FIGS. 4 to 15 represent analog sections through appropriate stiffening and planking panels 7 , 8 .

Between the individual projections 4 , 10 intersect the recesses 5 , 11 , whereby corresponding crossing points 17 are formed ge. The two-dimensional arrangement 3 , 9 formed in this way extends both uniformly in the longitudinal direction 22 and in the transverse direction 23rd

In Fig. 18, the arrangement of adjacent rows of projections 4 is arranged by about half a transverse extent of a projection 4 to each other. In this way, the recesses 5 are no longer continuous in a direction parallel to the transverse direction 23 . The recesses 5 running in the longitudinal direction 22 are still straight.

In Fig. 19, the protrusions 4 have circular cross sections. Correspondingly, a network of depressions 5 is formed between these spaced circles, each of which has 4 intersection points 17 between three adjacent projections.

In Fig. 20, a fourth embodiment for a two-dimensional array of protrusions 4 and recesses 5 is shown. The depressions are each triangular and two adjacent projections 4 along a row are rotated by 180 ° to each other. Two rows adjacent in the transverse direction 23 are each mirror images of one another.

In Fig. 21 a fifth embodiment for a two-dimensional array of protrusions 4 and recesses 5 is shown. This corresponds essentially to the arrangement of FIG. 18, wherein the projections 4 have a rectangular cross section with the shorter side of the rectangle parallel to the transverse direction 23 .

In Fig. 22 hexagonal projections 4 are surrounded by corresponding hexagonal recesses 5 arranged. Before the jumps 4 in adjacent columns are offset by half a dimension of a projection 4 to each other. The width of the depressions 5 is constant in each case, wherein again corresponding crossing points 17 are formed between three adjacent projections 4 .

In Fig. 23, the protrusions 4 have a dumbbell-shaped outline. As in the previous figures, the protrusions 4 are arranged in rows 35 and 36 and in corresponding columns. In the rows 36 , the projections are each arranged in the same columns, wherein they are arranged in the rows 35 between them, each offset by half a transverse extent of a projection 4 in the longitudinal direction 22 . In this way, the projections 4 are interleaved, with linear recesses 5 not being formed either in the longitudinal direction 22 or in the transverse direction 23 .

Fig. 24 shows a further network of protrusions 4 and Ver recesses 5 , both of which run ver wave-shaped in the longitudinal direction 22 .

In the ninth embodiment for a two-dimensional arrangement of projections and depressions according to FIG. 25, two different types of projections 4 and correspondingly adapted depressions 5 are arranged in a network. One type of protrusion 4 is circular and is surrounded by a circular recess 5 . Between each four these circular projections 4 are arranged substantially quadratic projections, concave edge regions being formed in the corresponding square corners. These concave edge areas are surrounded by the circular projections and cut out circular depressions. A rectilinear depression 5 connecting them is formed between each two adjacent circular depressions. Essentially, the depressions between the circular projections 4 run diagonally to the stiffening panel 7 , circular projections 4 of adjacent rows being arranged in a gap.

With regard to the arrangement of projections and depressions according to FIGS. 17 to 25, it should again be noted that a number of variations are possible. For example, the structures referred to as “protrusions” can be formed analogously as depressions and vice versa. The illustrated Ausführungsbei games can be formed only on one side and on both sides of the stiffening and planking panel. The two-dimensional arrangements or networks on the upper and lower flat sides of the panels can differ from one another, since, for example, an arrangement according to FIG. 19 on an upper flat side can be combined with an arrangement according to FIG. 21 on a lower flat side of a panel. Likewise, the projections and depressions can be formed in addition to a variation in their geometric shape with un different width, height and depth along a direction in the respective panel plane. So it is possible that the width of the projections or the recesses varies, for example, in the transverse direction of a board, while in the longitudinal direction height or depth of jumps and depressions varies.

Of course, only one stiffening or Be planking board alone and directly on the flat structure ana log as described above. The whole Variety of combination and variation options, like them at this point is partly described above not specifiable, but obvious to a specialist.
