Description

Technical field

[0001] The invention relates to a waste paper stand that is particularly easy to assemble and whose construction kit is as space-saving as possible. State of the art

[0002] Paper recycling bins typically have a rectangular base and four corner walls that define the boundaries of a stack of waste paper to be collected. These bins are very bulky and impractical for transport and shipping, as they cannot be stacked. Even if the four corner walls and the base are packaged separately, the rectangular shape of the corner walls still requires considerable space. Furthermore, complex fastening mechanisms, such as screws, are necessary for assembly, as buyers of such bins do not have the means to weld or rivet the corner walls to the base.

[0003] DE 200 04 017 U1, for example, shows a waste paper rack made of wood or plastic comprising a rectangular base and four side walls, wherein each side wall forms a first side part and a second side part by means of a right-angled bend of the side wall along an edge and is arranged at a corner of the base such that the first side part is arranged parallel to a first side of the base adjacent to the corner and orthogonal to the base, and that the second side part is arranged parallel to a second side of the base adjacent to the corner and orthogonal to the base. Description of the invention

[0004] One aim of the invention is to provide a waste paper rack that is easy to manufacture, easy to assemble, and space-saving in transport.

[0005] According to the invention, this objective is achieved by a waste paper stand, a construction kit for a waste paper stand and a method for assembling a waste paper stand according to the independent claims.

[0006] The perforated bend lines of the side panels allow them to be stacked flat over the base panel for packaging and transport. This enables highly optimized transport of the wastepaper rack, for example, by mail in a reinforced envelope. At the same time, the customer assembling the wastepaper rack can easily bend the side panels along the perforations to create right-angled corner walls for the rack.

[0007] The dependent claims relate to further aspects of the invention.

[0008] The fastening of the corner walls by inserting fastening tabs of the side panels into fastening recesses of the base panel and the subsequent bending of the fastening tabs allows for stable fastening and extremely uncomplicated assembly of the waste paper stand.

[0009] At the same time, the bent fastening tabs can serve as feet for the wastepaper stand. Brief description of the characters

[0011] Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. Figure 5 shows different views of an exemplary embodiment of a waste paper rack 1.

[0012] The waste paper rack has a base plate 2 and four side plates 3. The side plates 3 are bent at right angles along a perforated bending line 5 for easier bending, thus forming a corner wall with two side plate parts 3.1 and 3.2 arranged at right angles to each other. Each corner wall is arranged at one of the four corners along the two sides of the base plate 2 adjacent to the corner. Each side plate part 3.1 and 3.2 is arranged so that it rests at right angles on the base plate, and the side plate parts 3.1 and 3.2 are each arranged parallel to one of the two sides adjacent to the corner. The second side plate part 3.2, arranged on the longer side of the base plate 2, is wider (in the direction perpendicular to the bending line) than the first side plate part 3.1, which is arranged along the shorter side of the base plate 2. Between two side plate parts 3.1 or 3.There is a gap between the 2, which are arranged on one side of the base plate 2 and belong to two side plates 3, so that the fill level of the waste paper stand can be seen from all four sides.

[0013] Fig. Figure 6 shows a top view of the base plate 2 before assembly. The base plate 2 is flat and space-saving. It has two mounting recesses 7 at each corner. The first of the two mounting recesses 7 is arranged parallel to the first side of the base plate 2 adjacent to the corner. The second of the two mounting recesses 7 is arranged parallel to the second side of the base plate 2 adjacent to the corner, so that it is perpendicular to the first of the two mounting recesses 7. Both mounting recesses 7 are designed as slots. The width of the slot is greater than or equal to the thickness of the side plate. The length of the slot corresponds to the length of a [missing information - likely a specific component or element] associated with [missing information - likely a specific component or element]. Fig. 7 corresponding fastening tab 4 of the corresponding side plate 3, which is yet to be described. Preferably, the width of the slot is such that the fastening tabs 4 guided through the fastening recess 7 are prevented from moving at right angles to the longitudinal axis of the slot, since the slot edges abut the fastening tab 4 through which it passes.

[0014] Fig. Figure 7 shows a top view of the side panel 3 before it is bent. The flat side panel 3 has a thickness corresponding to the side panel thickness and can be transported in a particularly space-saving manner. The side panel 3 is perforated along a bending line as described above by the cutouts 5. This facilitates bending along the intended bending line. At the same time, it prevents the side panel 3 from being bent along the wrong bending line. By bending the bending line by 90°, a corner wall of the waste paper rack 1 is created. Four such side panels 3 must be bent for the four corner walls of the waste paper rack 1. Two must be bent by +90° (e.g., into the plane of the drawing). Fig. 7) and two must be bent by -90° (in the example mentioned, from the drawing plane of the Fig. 7).

[0015] The first side panel part 3.1 has a first fastening tab 4, which can be produced from the same side panel 3, e.g., by punching. The first fastening tab has a first part 4.1, which is connected to the first side panel part 3.1. Adjoining this on both sides, perpendicular to the bending line, are a second part 4.2 and a third part 4.2, which is separated from the first side panel part 3.1 by a slot. This slot corresponds to the thickness of the base panel 2. The first part 4.1 is separated from the second part 4.2 and the third part 4.2 by a fastening bending line, which also has an optional perforation 6. This first fastening tab 4 can now be inserted into the corresponding first fastening recess 7 of the base panel 2, thereby securing the first side panel part 3.1.1. The mounting bracket 1 can no longer be moved perpendicular to the longitudinal axis of the slot in the mounting recess 7 in the plane of the base plate 2. By bending the second part 4.2 and / or the third part 4.2 of the mounting tab 4, vertical movement of the side plate part 3.1 is prevented, since the slot between the side plate part 3.1 and the second / third part 4.2 corresponds to the thickness of the base plate. Preferably, the second and third parts 4.2 of the mounting tab 4 are bent inwards by 90°, so that the mounting tabs 4 each form a U-shaped base of the waste paper rack 1.

[0016] The second side panel section 3.2 has a second fastening tab 4, which is constructed analogously to the first fastening tab 4. By fastening the second fastening tab 4 analogously in the second fastening recess 7 of a corner, the right-angled bent corner wall is held in its shape. The length of the first fastening recess 7 is different from, preferably shorter than, that of the second fastening recess 7, and correspondingly the length of the first fastening tab is different from, preferably shorter than, that of the second fastening tab, so that the corner walls only fit into the two fastening recesses 7 of a corner in the correct orientation.

[0017] Alternatively, the fastening tabs could also be bent differently, e.g., directly after passing through the slot. However, the embodiment shown here is particularly suitable because, due to the vertical bend lines, the bent fastening tabs 4 are not at risk of being forced back into their untucked position by a vertical force on the side plates 3.

[0018] Thus, the waste paper rack 1 can be packed in a construction kit as a stack consisting of a base plate 2 and four identical side plates 3. Since both the flat base plate 2 and the four flat side plates are only the thickness of the sheet metal, optimal packing density is achieved. Additionally, no extra fasteners, such as screws, need to be included, as the fastenings are provided directly by the mounting tabs integrated into the side plates. The waste paper rack can be packed so flat that it can be sent by mail in an envelope.

[0019] Assembly is extremely simple thanks to the described design. The four side panels are bent 90° along the perforated bend line and, at each of the four corners, the two fastening tabs 4 are inserted through the two fastening recesses 7 in the base panel 2 of one of the corners. By bending the two parts 4.2 of the fastening tabs 4, the side panels 3 are locked in their assembled position.
