Description

Technical area

The invention relates to a display with a forwardly open stand of a folded and glued blank or stamped corrugated cardboard and at least one resting on lateral supports tray. Such a display is eg off DE 202 05 627 U1 known.

State of the art

Displays are used for the presentation and display of piece goods for sale, in particular flat-shaped piece goods. They include in addition to a forwardly open stand with side walls and also serving for the stabilization rear wall and possibly intermediate walls and trays and / or trays. These are arranged at different or the same distance depending on the type and quantity of the piece goods. The trays or trays are supported and / or suspended.

Trays are essentially self-supporting module elements, usually in the form of boxes, which are inserted or suspended in a display.

Unit loads distributed in large quantities are arranged or filled in displays by the distributors and provided after putting on a covering hood mentioned in the technical language Stülper, so that they survive unscathed the exertions of a transport.

The use of displays made of corrugated board with folded and glued trays and / or trays has opened up new perspectives. Space-saving and easily transportable blanks or punched items can be transported palletized to the distributor, folded and loaded there. After transport, they can only be put down at the retailer and the stropper removed.

Displays made of corrugated cardboard require special support at high loads, these must be charged relatively wide area. Moreover, the vertical beam positions must be predetermined, and replacement of the beams, if possible, is usually relatively cumbersome and delicate in terms of carrier loss.

Presentation of the invention

The invention has for its object to provide a display of the type mentioned, in which the carrier are more flexible.

The object is achieved according to the invention that the side walls of the stand are folded at least three layers, and that are pulled out of the middle layer on one side, reversibly punched out by a corresponding recessed from the inner layer window extractable tabs which form inwardly abkragende carrier for trays or as a hook serve. Specific and further developing embodiments of the invention are the subject of dependent claims.

For the sake of simplicity, only trays are mentioned here and below. Instead of trays, always or exclusively self-supporting trays can be used.

Although in particular folded and glued corrugated board trays are suitable for the displays according to the invention, it is within the scope of the present invention to insert trays of wood, plastic and / or metal, for example if it requires the carrying capacity, the stability, the mechanical or chemical resistance ,

The outermost layer of the three-ply sidewalls of a stand usually remains unchanged, the outermost cover sheet is used in particular as easily printable advertising space. From the middle layer, the aus-zuglaschen are punched, which are pulled out by a corresponding, punched out of the inner layer window.

When punching out enough space for pulling out must be created, on the one hand for moving the pull tab and on the other hand for reaching behind.

Like the other two layers and the middle layer of corrugated cardboard is relatively stiff, there are measures taken to facilitate the extraction of the pull tab. A proven means is the attachment of grooves, z. B. a center groove in the direction of the window and two laterally mounted groove in the direction away from the window. A lateral groove is attached to the middle layer in the region of the molding of the pull tab, a second side groove towards the free end of the pull tab. Thanks to the groove, the pull-out tab can, for example, be grasped and pulled out with a forefinger. Alternatively or additionally, in the punching machine the groove of the pull-out tab can be broken, certain zones of the middle and / or inner layer squeezed in the region of the Auszuglasche and so the withdrawal can be facilitated.

The mentioned three grooves have a common virtual intersection in their extension. The tips of the triangles formed by the groove have an angle α and the cutting lines form substantially trapezoidal surfaces with the grooves. The angle α between the middle and the two side grooves is suitably in the range of 20 ° to 45 °, in particular about 30 °.

The extracted extension tabs form a top and bottom open, tapering down truncated cone with an approximately equilateral triangular base. In this case, a horizontal stable support surface for trays is formed. These carriers are reversible because they can easily be pushed back into the side wall when not in use. By the tapered, underlying truncated cone border, which is supported on the lower edge of the window, the stability and the load capacity of the carrier is further increased.

The sliding guide of the extension tabs between the inner and outer layers of the side wall causes the pull-tab in each position is self-locking positionable. In particular, no special measures for stabilization must be made in the maximum extension position.

The two side grooves are positioned so that the pull tab lies in the area of downwardly tapered punched edges of the window. More precisely, the lower part of the window tapers in a trapezoidal shape, as a result of the folding in this area, the projecting truncated cone lateral surfaces lie laterally on the window and are thus stabilized in an optimum position. The windows must have a free space for engaging behind the extension tabs.

The mentioned trapezoidal, lateral boundaries of the windows form an angle β of (0.3 - 0.7) α, in particular about 0.5 α. The best ratio of the angle α to the angle β is determined case by case by calculation and / or by experiments.

As a rule, the stand of a display according to the invention has an interior which is open towards the front. It can also be arranged one or more partitions, creating a multi-part display. The intermediate walls suitably comprise six layers, which stabilizes the display as a whole. On both sides of the partitions can be formed by pulling out of pull tabs carrier and removed if necessary by simply pushing away without an item of the display must be added, replaced or removed.

Purely functionally, an intermediate wall could also comprise only five or even only three layers, but this would be complicated in terms of production technology and, in particular, less stable in three layers and restricted with regard to the position of the trays.

In a display, the windows with the extension tabs are usually arranged vertically above one another in the front and rear area of the side and any partitions. It is expediently formed a regular grid, in which the windows with the underlying extract tabs have a distance of in particular half to double window height.

As a rule, the laterally stabilized trays are placed forward on the unfolded carrier without slip-protection. It can also be taken special measures to prevent slipping forward, for example, by a comb in the insertion of the trays a form-fitting engages in correspondingly recessed corresponding slots of the inner layer.

Furthermore, the extension tabs in the area of the center groove can have a latching nose which engages in a form-fitting manner in a corresponding recess of the shelves and thus forms a secure position against slippage of the shelves. As mentioned, the position safeguards can be formed individually or cumulatively.

Finally, when inserting the trays abkragende parts can be performed in the carrier.

With a locking lug single or all abkragenden pull tabs can be used instead of a shelf support as a hanger. Such hangers can also be on the Be provided outside of the side walls of the display, if their windows and pull-tabs are arranged accordingly, ie outside the range of the tray carrier.

Although the shelves are usually inserted horizontally, they can also be used obliquely for special purposes, for example, for presentation purposes without great burden on the trays. At higher load and predictable insertion of the shelves in an inclined position, the cut of the pull tab can be adjusted accordingly.

The inventive display allows a versatile use, carriers can be arranged as required by pulling out the extension tabs and removed by pushing in again. It is a variable arrangement of trays, possibly also trays, possible without inserting or removing of separate carriers, so without additional material costs. It can also be produced carriers with relatively large load surface, which can be a major advantage in corrugated board.

The invention will be explained in more detail with reference to embodiments shown in the drawings, which are also the subject of pending claims.

Ways to carry out the invention

A display 10 made of corrugated cardboard substantially comprises a stand 12 with six horizontally inserted trays 14, a bottom 16 and a claw 18, the latter as a decorative design element.

The stand 12 is viewed from above substantially U-shaped, with two side walls 20, 22 and a rear wall 24. The likewise folded and glued corrugated trays 14 are placed on pulled-out, designed as a carrier 26 Auszuglaschen 54, which hereinafter in detail are shown and described.

The inner layer 32 of the side walls 20, 22 has horizontal longitudinal slots 28, in which an optionally formed comb of the tray 14 positively engages and prevents slipping forward. The region of these longitudinal slots 28, like all other recesses of the inner layer 32 of the side walls 20, 22 thanks to a virtually invisible, corresponding perforation of the inner layer 32 easily removable with a finger. Optionally, the inner layer 32 of the side walls 20, 22 with a cover sheet 106 (FIG. Fig. 5, 7 ) obscured. Along the contours of the recesses runs a perforation, which is only pressed in when needed. Between the uppermost and second uppermost tray 14, the region of the horizontal slot 28 is not yet removed or still covered and therefore not visible.

Fig. 2 shows a blank or diecut for a side wall 22 of the stand 12. The blank is formed substantially in three parts and comprises a middle layer 30, an inner layer 32 and an outer layer 34. These layers are separated by double grooves 36, 38, wherein the distance between the two lines of double rill 38 is bigger than at Double groove 36. When folding, first the middle layer 30 is placed on the inner layer 32 and then the outer layer 34 on the middle layer 30. Finally, the adhesive flap 40 is folded over a wider wider double groove 42 and glued in a recess 31 of the inner layer 32 with the middle layer 30 , whatever Fig. 1 is apparent.

Another longitudinally integrally formed via a single groove 44 on the outer layer 34 adhesive flap 46 is used to connect to the rear wall 24 (FIG. Fig. 1 ). Finally, a third adhesive tab 48 is integrally formed on the inner layer 32 on the lower narrow side via a single groove 50, which the connection to the bottom 16 (FIG. Fig. 1 ) serves.

From the inner layer 32 grid-shaped two vertically superimposed series of windows 50 are punched out. The distance a of these windows 50 is expediently constant; it is generally (0.5-2) h, the height h of the windows 50.

In a pattern corresponding to the windows 50 horizontal, elongated openings 52 are recessed from the inner layer 32 or bounded by a perforation. Optionally, a pinch zone may be formed in this area.

In the region of the grooves 52, longitudinal glue tracks L extend for bonding to the middle layer 30, which likewise has corresponding glue traces L.

From the middle layer 30 are shown below ( 3 and 4 ) shown Ausauslaschen 54 punched out, which pass through the window 50 after lying around the double groove 36 and rest below.

The outer layer 34 has neither punched holes nor other changes, it remains intact and is finally folded around the double groove 38.

The waves of the corrugated board run in the longitudinal direction, which is indicated by 56. Also indicated is a glue trace L on the tab 46 of the outer layer 34.

The side wall 20 thus consists of three superimposed and glued individual layers of corrugated board. In the Fig. 2a shown in cross-section single layer has a double shaft 58.60. The corrugated cardboard has two cover sheets 62, 64 and a release sheet 66. The larger shaft 58 in this case has a wave height of about 3 mm, the smaller shaft 60 has a wave height of about 1.5 mm.

A Ausluflasche 54 punched out of the middle layer 30 is in Fig. 3 shown in detail. This extension flap 54 is integrally formed on the present right side of the middle layer 30. The punching line 72 extending from the corner 68 to the corner 70 remains closed when the flat pull tab 54 is flat. From the corner 70 to the corner 74, two punching lines 76, 78 extend, which create a free space 80 for displacing the free end 82 of the extension latch 54 and a clearance 84 for engaging behind the extension latch 54.

The extension flap 54 has three grooves, the extension of which has a virtual intersection point S. A center groove 86 extends to two side grooves 88, 90 at an angle α of about 30 ° in the present case. The three grooves facilitate the extraction of the pull tab 54 or make this possible.

In the area of the center groove 86, a detent 92 is formed. The two limited by the center grove 86 faces of the extension flap 54 between the side grooves 88, 90 are cut off in the direction of the virtual intersection point S so that they form two support edges 94 for the carrier 26.

The side groove 90 forms the molding of the extension tab 54 to the middle layer 30, this groove extends between the corners 68 and 74th

Fig. 4 corresponds to Fig. 3 However, the substantially trapezoidal shaped surfaces of the extension tab 54 are raised between the grooves 86, 88 and 86, 90, while the surface with the free end 82 in the plane of the middle layer 30 remains. Due to the crest-forming raising of the area between the side grooves 88, 90, the free end 82 of the extension tab 54 has moved with a pivoting movement in the direction of the arrow 96. This pivoting movement is limited by a fixed stop surface 98 and a mobile stop surface 100.

In practice, behind the middle layer 30, the outer layer 34, which is visible in the region of the free spaces 80, 84, and the inner layer 32 lying in front of the middle layer 30 with a corresponding window 50 (FIG. Fig. 2 ) arranged.

Fig. 5, 6 show a not yet pulled out or a back pushed back into the side wall 20 Auszuglasche 54, Fig. 7, 8 one of the side wall 20 abkragende pull-tab 54 with a support surface 102 for trays 14th

In the window 50 of Fig. 6 the extension tab 54 with the Mittelrill 86 is visible. It is according to Fig. 5 substantially flat in the side wall 20. The window 50 is trapezoidal in the region of the extension tab 54, downwardly at an angle β to a support surface 104 tapers, which carries the support edges 94 of the extension flap 54.

Out Fig. 5, 7 is a cover sheet 106 recognizable, which according to Fig. 5 extends over the entire interior of the side wall 20 before use. This cover sheet 106 has in the region of the peripheral outer contour 108 of the window 50, a perforation 109, which before pulling out the extension flap 54 according to Fig. 7, 8 is pressed. If no cover film 106 is arranged, a perforation extends beyond the outer contour 108 of the window 50 of the inner layer 32.

The extraction of the pull tab 54 according FIGS. 7 and 8 is first limited when the mobile side grill 88 ( Fig. 4 ) reaches the corresponding outer contour 108 'of the window 50. The angle α / 2 between the center groove 86 and the side groove 88 (FIG. Fig. 3 ) and the angle β ( Fig. 6 ) are arranged in the trapezoidal area 108 ', 108 "of the window 50 in such a way that the pull tab 54 rests and is angled with the side groove 88 of the contour 108'. ,

The carrier 26 formed in this position has optimum properties, if according to Fig. 4 the stop surfaces 98 and 100 lie on each other.

If no tray 14 ( Fig. 1 ) is inserted, the carrier 26 can also serve as a hook. Even in the outer layer 34 may occasionally blind, ie hidden carrier 26 according to Fig. 7 be arranged, which are pulled out when needed and used as a hook can. If they are no longer needed, they can be sunk and possibly covered again.

The FIGS. 9 and 10 show blanks for a tray, where Fig. 9 on the tray shell 110, Fig. 10 refers to the tray insert 112.

To achieve a high load capacity, the tray insert 112 is folded from corrugated cardboard three times and glued along glue tracks L. The finished four-layer tray insert 112 is packed with the layer 114 down in the tray shell 110. This lowermost layer 114 has on both end faces a comb 116 which passes through the applied tray shell 110 through the long-rectangular slots 118 and upon insertion of the tray 14 in the stand 12 in the longitudinal slots 28 (FIGS. Fig. 1 ) is introduced. The holes 120 mounted in the end-side corners of the lowermost layer 114 of the tray insert 112 serve to receive latching noses 92 (FIG. Fig. 6, 8 ) of the pull-tabs 54. The front-side fold-over pockets 122 of the tray shell 110 have corresponding holes 124. The end-side and the longitudinal-side fold-over tabs 122, 126 are glued together in the usual way.
