Connector for decorative or advertising boards

The invention relates to an E-shaped connector for the clamping connection of printed decorations or Cardboard billboards.

Such panels have texts, images or the like on their front for decorative and / or advertising purposes. Included the arrangement is often made so that on a single panel there are only partial images that are continue on the neighboring boards. With that you can

create diverse combinations of text and images for display purposes. With the one on the back The edge bead not only gives the board the necessary rigidity, but also appears optically as a solid part. Through the Bulges that appear massive are also used when punching or punching the front side opens up a wide range of decorative options for depth = design.

Various elements are known for connecting such panels. For example, U-shaped brackets are used, which overlap the inside of the edge bulges of two adjacent panels and the two edge bulges and thus the two Press the panels together. Elements are also known which are pierced into the edge beads between the panels and so keep the boards in place. Finally, E-shaped connecting pieces are known, the upper and lower Bars encompass the edge bulges of neighboring panels and the middle bar is pushed between the two edge bulges. In this way, a space corresponding to the width of the Ε-beam is created between the plates. This E-shaped Connectors have long been used in solid or partially hollow plastic.

All known embodiments have the disadvantage of comparatively high material and manufacturing costs. This disadvantage is particularly serious because the connecting piece only fulfills a technical puncture, without in any way the decorative and pursued with the panels Support advertising effect. So it is technically necessary, but exclusively expensive acting element. In addition, they require a relatively large packaging and storage space.

These disadvantages are according to an earlier suggestion

(G 7 l4? 755.9) eliminated by the fact that the connecting piece

from a rectangular blank with two parallel, elongated cutouts by bending two perpendicularly for this purpose arranged at a small distance from each other and at the same distance from the marginal edges of the blank FaI * lines is formed. The entire production process exists practical in cutting and punching as well as bending bz «. Folding the blank to form a connecting piece which is U-shaped in cross section and E-shaped in view. The material and production costs are therefore low.

For panels with a large area in particular, which therefore have a correspondingly greater weight and less torsional rigidity, the connecting piece described above can be used may be weak. The invention is therefore based on the object of providing the connecting piece with greater stability with only insignificantly greater material expenditure and demand To lend packing or storage space.

To solve the problem, the invention is based on the latter called connecting piece. from, that is, from a rectangular blank with two parallel elongated cutouts by bending by two perpendicular to this at a small distance from each other and at the same distance from the to them crease lines arranged parallel to the cut edges are formed into a U-shaped cross section, the U-legs and webs of which, next to the cutouts, form the crossbeams form. According to the invention, this connecting piece is characterized in that at least one long cutting edge each section is interrupted in the area between the two kink lines and replaced by a material-Schwäcbiungslinie, around which the remaining, in cross section turn U-shaped parts in the space between the

Ε-crossbars forming U-legs are pivotable.

The parts remaining between the cut edges are consequently immediately used for Veisteifüng dsr E = Qusrbslksn used, so that a total of a rigid structure arises. The connecting piece can therefore be produced without material waste and can be packaged in a flat form and be kept. By folding it into a U and pushing it onto the edge bulges, it fulfills the connection purpose, with the remaining between the cut edges Swivel parts automatically into the space of the Ε crossbar.

According to a further feature of the invention, both can long cut edges of each cutout in the area between the crease lines and one parallel to them middle «cut edge should be provided continuously so that the parts remaining on both sides of this continuous cutting edge can be pivoted in the direction of one of the two adjacent Ε crossbars. That way will every Ε crossbeam stiffened.

To further stiffen the connecting piece, the invention provides that the cardboard blank is parallel to the Has crease lines extending edge tabs, which are glued together after folding the blank to form a U, so that a closed sleeve is created.

According to the invention, the connecting piece described above can also be used as a stand for the panels, in that it consists of a cardboard blank which is folded into a closed, rectangular cross-section and has only one cutout, with a cut edge of the cutout between two adjacent rectangular edges

Foil coated panel 5 on the edges too an edge bead 6 of e.g. square cross-section is folded over. The bead 6 runs out, as in particular Figure 2 recognizable to the entire plate. The entire stand stands on feet 7.

Adjacent panels are held together by the E-shaped connecting pieces 9, which can be seen in a side view in FIG. These connecting pieces 9 accordingly have an upper transverse beam 10, a middle transverse beam 11 and a lower transverse beam 12, which are connected to one another by a longitudinal beam 13. The middle bar 11 engages between adjacent plates 1, 2 or 3t ^ or · I ₁ 3 and 2, k. In contrast, the two outer bars 10 and 12 encompass the bead on the inside.

FIG. 3 shows the blank from which the connector is formed. This blank Ik is rectangular and has two elongated rectangular cutouts which are arranged parallel to one another at a small distance. Each section is delimited by two long cut edges 15'16 and two short cut edges 17'18 running perpendicular thereto, which are indicated by strong solid lines. Crease lines 19, 20, drawn in dot-dash lines, are provided perpendicular to the longitudinal extent of the cutouts or perpendicular to the long cut edges 15, 16, which are arranged a short distance from one another and at the same distance from the short cut edges 17, 18 parallel to them. By bending the blank around these lines 19 '20 of these can form U are placed in an as k in Figure recognizable) thereby forming the existing between the fold lines 19, 20 face ends U-web 21, and the right and left of them existing surfaces the U-legs 22, 23.

In the embodiment shown, the U-profile is closed on its usually open side. For this purpose, the blank 1k (FIG. 3) also has edge tabs 24, 25 which are delimited by crease lines 26, 27. By bending the edge tabs 2 ^, 25 around these kink lines and gluing them together, a sleeve 28 with a rectangular cross-section is produced (see FIG. K) .

One long cutting edge 15 of each section is interrupted in the area between the folding lines 19, 20 and replaced by a weakening line 29, 30, which is shown in phantom in FIG. In FIGS. 5 and 6 it is shown how the piece which is U-shaped or rectangular in cross-section becomes an E-shaped connecting piece. The parts 31, 32 bounded by the cut edges 15 to 18 via the Schwäcbungslinien 29ι 30 still connected to the blank, as can be seen in Figure 5 li-aJcs, initially also have a U-shaped cross-section. By folding in these parts 31 * 32 - an intermediate position is shown on the right in FIG. 5 - rectangular recesses (33 * 3 ^) * are created in the space between the crossbars 10, 11, 12 and the longitudinal bar 13 of the E-piece 9 are delimited (Figures 1 and 6). In the left view in FIG 6, the part 31 is complete, as folded in the right illustration half · The U-crosspieces of these parts stiffen in the folded-L & S ^e, the legs 22, 23 of the sleeve 28. Before engaging the parts 31, 32, the sleeve 28 can be brought into a flat, double-layered shape according to FIG. 7 by pressure on diagonal folding lines 19, 27 or 20, 26.

In Figures 8 and 9 the connector is for use as a Stand 7 shown. In this case it only indicates something
