Description

(1) Further features, details and advantages of the invention become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings, in which:

(2) FIG. 1 shows a schematic perspective view of a light box, wherein a front part is being shown lifted up from a rear part;

(3) FIG. 2 shows a schematic view of a light box, wherein a front part and a rear part are shown lying next to one another;

(4) FIG. 3 shows a schematic cross section through a light box;

(5) FIG. 4 shows a schematic perspective view of a rear part of a light box, which is being rolled up to form a roll;

(6) FIG. 5 shows a schematic perspective view of a light box, wherein its front part and its rear part are being rolled up together to form a roll; and

(7) FIG. 6 shows a schematic perspective view of a light box group having two light boxes.

(8) FIG. 1 shows a light box 1 in a schematic perspective view. The light box has a front part 10 with a rectangular front side 11 and a rear part 20 with a rectangular rear side 21.

(9) The front part 10 is shown lifted up from the rear part 20. The main element of the front part 10 is a printable, translucent, and rollable front plastics plate 12, which forms the front side 11 and which has a perimeter edge 13. The front plastics plate 12 can be printed, for example with a motif, a logo and/or text. Furthermore, the front plastics plate 12 is folded using folding lines 16 to form a box-like body 17 having side parts 18. It cannot be seen from this perspective that a first connecting strip (cf. reference sign 14 in FIGS. 2 and 3) is fixed on the side parts 18. The front side 11 adjoins the side parts 18 along the folding lines 16, wherein the side parts are brought into a position standing perpendicularly away from the front side 11 along the folding lines 16 in order to fix the front part 10 in front of the rear part 20.

(10) The four side parts 18 of the front plastics plate 12 have a uniform width B1 orthogonal to the respective corresponding folding line 16, as can be seen in particular in FIG. 2. The corners between the four side parts 18 are each cut out. FIG. 2 also shows that the peripheral first connecting strip 14 of the front part 10 is fixed on an inside 15 of the front plastics plate 12 opposite the front side 11 and extends at least substantially along the entire perimeter edge 13 of the front plastics plate 12. The first connecting strip 14 is flexible or elastically deformable and is composed of four first strip segments 14a, 14b, 14c, 14d, which are lined up one behind the other and each fixed on one of the four side parts 18. The first connecting strip 14 is a magnetic strip. The width B2 of the first connecting strip 14 is slightly smaller than the width B1 of the side parts 18, with the result that the widths B1, B2 substantially correspond.

(11) The rear part 20 according to FIGS. 1 and 2 has a rollable rear plastics plate 22, which forms the rear side 21. The rear plastics plate 12 is opaque and/or light-proof and has a perimeter edge 23. In addition, the rear part 20 has a peripheral second connecting strip 24, which is fixed on the rear plastics plate 12, in particular on the rear side 21 according to FIG. 1 and, in deviation from this, on an inside 25 of the rear plastics plate 22 opposite the rear side 21 in FIG. 2. The second connecting strip 24 extends at least substantially along the entire perimeter edge 23 of the rear plastics plate 22.

(12) According to FIG. 1, the rear plastics plate 22 is folded using folding lines 26 to form a box-like body 27, wherein the box-like body 27 has, adjacent to the rear side 21, side parts 28 on which the second connecting strip 24 is fixed. According to FIG. 2, the side parts 28 lie in the plane with the rear side 21. The corners between the four side parts 28 are each cut out. In particular, the rear plastics plate 22 is rectangular with four side edges, wherein, adjacent to the four side edges, in each case a folding line 26 for forming the side parts 28 extends, wherein the four side parts 28 are able to be brought into a position standing perpendicularly away from the rear side 21 along the folding lines 26 in order to fix the front part 10 in front of the rear part 20. The side parts 28 of the rear plastics plate 22 have a uniform width B3 orthogonal to the respectively corresponding folding line 26. The width B4 of the second connecting strip 24 is slightly smaller than the width B3 of the side parts 28 and thus at least substantially corresponds to this width B3 of the side parts 28. At the same time, the width B1 of the side parts 18 of the front plastics plate 12 corresponds at least substantially to the width B3 of the side parts 28 of the rear plastics plate 22.

(13) The second connecting strip 24 is flexible or elastically deformable and is composed of four second strip segments 24a, 24b, 24c, 24d, which are lined up one behind the other and each fixed on one of the side parts 28 of the rear part 20. The second connecting strip 24 is also a magnetic strip.

(14) Furthermore, an electrical light-emitting unit 30 consisting of LEDs distributed over the rear side 21 is fixed on the inside 25 of the rear plastics plate 22. The light-emitting unit 30 is, in particular, LED strips that extend parallel to one another.

(15) How the front part 10 and the rear part 20 according to FIG. 2 can be assembled can be seen from the schematic cross section according to FIG. 3. Here, the front part 10 is fixed in front of the rear part 20 by way of the first and second connecting strips 14, 24. In this assembly, the side parts 18 of the front plastics plate 12 lie on the outside of the side parts 28 of the rear plastics plate 22.

(16) With an arrangement of the second connecting strip 24 as shown in FIG. 1, it would theoretically be possible that the fixing of the front part 10 in front of the rear part 20 comprises direct contact between the first and second connecting strips 14, 24. According to the variant according to FIGS. 2 and 3, however, the fixing of the front part 10 in front of the rear part 20 comprises a spacer between the first and second connecting strips 14, 24, with the spacer being the rear plastics plate 22 and in particular its side parts 28.

(17) The fixing of the front part 10 in front of the rear part 20 by way of the first and second connecting strips 14, 24, here both magnetic strips, makes a connection V possible that is releasable without damage and is based on magnetism. In the case of an arrangement according to FIG. 1, adhesion or a hook-and-loop fastening connection could be used as a connection V between the first and second connecting strips 14, 24, which is releasable without damage.

(18) The extension of the connecting strips 14, 24 almost completely along the side parts 18, 28 results in a connection V between the first and second connecting strips 14, 24, which is releasable without damage and extends at least substantially around the perimeter.

(19) FIG. 4 shows a schematic perspective view of a rear part 20 of a light box, which is being rolled up to form a roll R2. With regard to the technical features, this rear part 20 corresponds to the refinement according to FIG. 2, for which reason reference is made to the passages of the description belonging to FIG. 2 in order to avoid repetition. As can be seen, the LED strips of the light-emitting unit 30 extend transversely to the rolling direction.

(20) FIG. 5 shows a schematic perspective view of a light box 1, which, however, is not mounted. Rather, its front part 10 and its rear part 20 are rolled up together, lying one on top of the other, to form a roll R3.

(21) FIG. 6 shows a schematic perspective view of a light box group 50 having two light boxes 1. The two light boxes 1 adjoin one another in an adjacent manner in such a way that the front sides 11 of the two light boxes 1 are arranged next to one another. By way of their first and second connecting strips 14, 24, both magnetic strips, the light boxes 1 are fixed to one another via a connection V2, which is releasable without damage.

(22) The invention is not restricted to one of the embodiments described above, but can be modified in a wide variety of ways.

(23) All of the features and advantages, including structural details, spatial arrangements, and method steps, arising from the claims, the description, and the drawing may be essential to the invention, both individually and in a wide variety of combinations.
