Description

The invention relates to a flat carrier, in particular for the inclusion and presentation of goods, at least an upper and a lower plate, being in the lower plate a number of between a starting position and one Use position swiveling, hinge-like, on the Lower plate hinged retaining tabs are formed and the Top plate a corresponding number of holding openings has, from which the retaining tabs for holding the goods in project their use position.

Such a carrier is known from practice Bottom plate and top plate manufactured separately, in the Lower plate the holding tabs and in the upper plate slot-shaped holding openings are formed, in which in their Use position pivoted retaining tabs are inserted.

In the known carrier is disadvantageous in that Assembling the top and bottom plate an exact assignment of holding tabs and slot-shaped holding openings necessary is. Furthermore, the retaining tabs must be completely in their Use position aligned to assemble them of the flat carrier in the corresponding holding openings to be able to plug in. For example, shows the material of the The base plate has a certain elasticity, which remain Holding tabs not independently in their position of use, but at least partially move into theirs Starting position back. This is the correct alignment of the holding tabs relative to their holding openings labor intensive and time consuming.

Furthermore, for the manufacture of the surface carrier from and top plate usually a connection of both plates, for example by gluing. In this case the flat carrier to a customer only with already in Delivered in the use position pivoted holding tabs become. Otherwise, the assembly and connection of the Plates made by the customer, which is what this usually does is unreasonable. But if the carrier is already in delivered ready for use, so the Retaining tabs damaged or even unusable during transport become.

The invention is therefore based on the object mentioned carrier to improve that Assembly is simplified and done in less time can, at the same time the carrier without risk of a Damage to the retaining tabs can be transported.

To solve this problem, the above is distinguished Carrier characterized in that the top and bottom plate with the Holding tabs lie one on top of the other in their starting position and each holding opening is part of a passage opening, through which swivels the retaining tab into its use position are and in which at least one in the swiveling path of the Holding tabs arranged, the holding tabs in their Supporting locking projection protrudes into the use position.

In this way, the carrier with the holding tabs in Starting position to be transported to the customer. The Assembly of the carrier from the top and bottom plate is simplified because the retaining tabs in their starting position are and an exact assignment to the corresponding Holding openings is in no way necessary. Top and The base plate is simply placed on top of one another and accordingly connected with each other. By training the The holding tabs are only opened when they are used the wearer swiveled into their position of use, for what only less time and effort is required. The corresponding holding opening is part of the Passage opening, with the holding tabs in the pivoting path a locking projection is arranged, the holding tab in their Support position of use, taking it out of the holding opening protrudes. The pivoting of the retaining tabs in the Use position can, for example, simply manually be done by holding each tab individually from their Starting position through the passage opening in the Use position is pressed.

Around the passage opening with the smallest possible size to be able to train, it proves to be an advantage if the Locking projection partially limits the holding opening. In the As a rule, the holding opening is in an end region of the Passage opening formed, the locking projection the Holding opening opposite the rest of the passage opening partially delimited.

Depending on the size of the retaining tab and for better stabilization the retaining tab in its position of use it is still of advantage when locking projections in opposite to each other protrude the passage opening. The locking projections can be constructed in the same way.

In the simplest case, the retaining tab and passage opening are in the essentially geometrically similar. That is, the outlines of Holding tab and passage opening are except for the Locking projections of the same shape, with the passage opening is usually larger in cross-section than the retaining tab.

In a simple embodiment, the holding tab has a U-shaped outline and is in the area between theirs U-leg ends pivotally connected to the lower plate. In the position of use, the retaining tab thus has one reverse U-shaped shape.

Various materials can be used for such a carrier, which can be used, for example, as a shelf, tray, installation surface or the like. For ecological and economic reasons, it is advantageous if the top and / or bottom plate are made from a single or multi-layer cardboard or corrugated cardboard, the through openings being punched out of the top plate and the retaining tabs being cut out of the bottom plate.

To simplify manufacturing and to simplify Recording and presentation of goods are holding tabs and Through openings arranged in parallel rows.

For connecting the top and bottom plate and thus for Manufacture of the flat carrier are different Connection techniques applicable. For example, the Plates are tacked together. The cheapest is one at least in places, the panels are glued together.

The manufacture of the carrier continues simplified that top and bottom plate from a single Blanks are made, with bottom plate and top plate for folding the lower plate onto an underside of the upper plate are connected to each other via at least one creasing. In this way, a complete carrier is made of one Cut can be produced, with regard to the assignment of Retaining tabs and passage openings when stacked no problems occur from the top and bottom plate, because the Folding is specified and the correct assignment guaranteed.

The lower plate does not have to be in one piece, but can for example from two foldable, with the top plate connected plate halves can be formed.

For essentially rectangular beams it turns out to be in this connection continues to be advantageous if the top plate is also substantially rectangular and the lower plate or the bottom plate halves along one or both longer sides of the rectangle is connected to the top plate or are. It is also possible to use the shorter rectangular sides of the top plate. As well For example, the top plate can be divided into two parts one-piece base plate or both plates can be made accordingly be divided.

To be folded over on the underside of the top plate Subplate halves are essentially complete Obtaining the base plate, it is advantageous if the Halves of the lower plate when folded onto the underside of the Top plate facing edge or butt edges are complementary to each other.

For example, a cover or on the flat carrier to arrange another flat beam suggested that at least in the top plate Insert slots for inserting supports for the cover or the further carrier are formed.

In order to set up and present goods through the supports in to influence the least amount, the Insertion slots parallel and / or perpendicular to the rows of Passage openings.

Around the retaining tabs, especially with a lower plate Simply swivel the cardboard or corrugated cardboard in a hinge-like manner to be able to, is in the lower plate between the U-leg ends a groove is formed on the retaining tab.

The pivoting of the retaining tab can continue be simplified that the creasing approximately in the middle Includes cutting line. Creasing and cutting line can already when making the one-piece blank or together with punching out the openings or cutting out the Retaining tabs are made.

In a preferred embodiment, the Through openings a substantially closed U-shaped Outline, each with a locking projection of opposite points of the U-leg protrudes.

The locking projections can have different shapes. The locking projections preferably have essentially the shape a right triangle, the hypotenuse of which is Locking slope is formed, the locking projection by means of of the longer cathets with the associated U-legs of the Passage opening is connected.

To the holding tabs in the use position safely and with to support little play, the holding opening has a width or length that is at least equal to the material thickness or Width of the retaining tab is.

Should be a flat beam using the supports mentioned above be arranged above a wider flat beam, So it is an advantage if the slots are also in the Bottom plate are formed with those in the top plate trained insertion slots can be brought into cover. On in this way the flat carrier can be stacked Carriers both as a lower, middle or upper carrier be used.

It has already been mentioned that the retaining tabs are only at Use of the carrier for receiving and presenting goods in the position of use can be pivoted manually. It can for example, only a selection of holding tabs in the Use position pivoted or a number of Retaining tabs pivoted back to their starting position become. This allows for variations in the performance of the Goods and a use of the carrier for goods different sizes. Small goods can for example, all retaining tabs in the use position be pivoted. The goods will then be sent to the Holding tabs, for example, attached. For larger goods can only arrange every second along a row Retaining tabs are pivoted in the position of use.

To pivot the retaining tabs into their use position to simplify is a device suggested that at least a number of with the Retaining tabs from the back of the base plate of the carrier has stamps which can be brought into the system and which have a Comparison to a cross section of the passage openings in the Upper plate of the carrier have a smaller cross section, wherein the row arrangement of the stamps is at least partially one Row arrangement of retaining tabs and passage openings equivalent. For example, are four retaining tabs and Through openings arranged per row, for example a device with two stamps can be used on the two retaining tabs in the starting position and Appropriate through openings of each row can be placed are. Then the carrier can be manually postponed along the stamp pressed down, causing the stamps to hold the tabs in swivel the position of use. In the extreme case it is Device with only one stamp is sufficient.

When all holding straps are swiveled into the position of use it is advantageous if the stamps with the Holding tabs and passage openings of the appropriate number and arrangement are formed.

The device can be constructed very simply from for example a base plate and the stamps, the Stamp from the base plate essentially vertically protrude.

At their tips, the stamps can be flat, concave or convex be formed, with convex, i.e. rounded, Stamp tips are preferred.

The pivoting of the retaining tabs and the assignment of the Carrier to the stamps can also be automated by for example, a counter stamp is assigned to the stamps, on which the carrier is releasably attached and relative to the Stamping is movable, being between stamp and Counterstamp guides for the counterstamp and / or the Carriers are arranged. The counter stamp shows corresponding openings for receiving the stamp and the in Use position pivoted holding tabs.

In the following an advantageous embodiment of the Invention based on the figures enclosed in the drawing explained and described in more detail.

The lower plate halves 20 and 21 are complementary to one another trained what in particular the course of the corresponding Edge or butt edges 24 and 25 relates. In every Subplate half 20, 21 is at least one row of four Holding tabs arranged in the longitudinal direction of the carrier 1. The Retaining tabs 6 are in their initial position 4, in which they arranged flush in the corresponding plate halves are. The retaining tabs are essentially U-shaped with U-legs 12, 13 and a connecting U-web 14. Zur hinge-like linkage to the respective Lower plate half, is in an intermediate area 15 between U-leg ends 49, 50 of the respective U-legs 12, 13 a Groove 28 formed. In the groove 28 can be approximately in the middle a cutting line 29 may be arranged as in the lower one Holding tab 6 of the lower plate half 21 is shown enlarged is.

In addition to the four-row of retaining tabs, each has Lower plate half 20, 21 another and parallel to Row of four arranged two rows of retaining tabs 6.

Furthermore, there are two in each subplate half 20, 21 Insert slots 40, 41 formed, of which the Insertion slots 40 parallel to the rows of retaining tabs and between these and the insertion slots 41 perpendicular to the Extend rows of retaining tabs.

The bottom plate halves 20 and 21 are along one side via a double folding groove 19 with the top plate 2 connected.

In the representation according to FIG. 1, it should be noted that at upper and base plate 2, 3 made of cardboard or corrugated cardboard corresponding fiber / shaft direction parallel to Longitudinal direction, i.e. parallel to the row arrangement of Retaining tabs is aligned. The plates 2, 3 1 at their upper and lower ends in FIG Wave cut on by the double-dash lines is shown.

The top plate 2 is essentially rectangular with longer rectangular sides 22 in the longitudinal direction and shorter Rectangular sides 23 transverse to the longitudinal direction. On the longer ones Rectangular sides 22 is the top plate 2 with the Subplate halves 20 and 21 connected.

In the top plate 2 are three rows of four in each Longitudinal openings 8 are arranged. These have an approximately U-shaped cross section with U-legs 30, 31 and a U-web 32 connecting them. In Each passage opening 8 protrudes two locking projections 10, 11th These are from opposite locations of the U-legs 30, 31 in the passage opening 8 before. The locking projections 10, 11 have the shape of a right triangle. Whose Hypotenuse 33 is inclined from the respective U-legs 30, 31 protruding inlet or locking slope and its shorter Catheter 35 as a stop for one in a holding opening 7 inserted retaining tab 6 in the use position 5 according to FIG. 3 educated. The corresponding longer catheter 34 Locking projections 10, 11 run in the direction of the U-legs 30, 31, being part of these U-legs.

The passage openings 8 are geometrically similar to that Retaining tabs 6 formed, both in the longitudinal direction the top 2 and larger dimensions in the transverse direction than the retaining tabs.

Between and parallel to the longitudinal ones Rows of retaining tabs 8 are two insertion slots 26 and transverse to the longitudinal direction and in the middle row arrangement of holding tabs are two further insertion slots 27 in the Top plate 2 formed. These are also geometric similar to the respective insertion slots 40 and 41, respectively the insertion slots in the lower plate halves 20, 21 a have greater length and width.

The holding openings 7 are part of the passage openings 8, the holding openings 7 at one end of the Passage opening 8 arranged and partially through the shorter cathets 35 of the locking projections 10, 11 are limited.

The length 37 or width 36 of the holding openings 7, see middle row of retaining tabs in Fig. 1, is larger or equal to the corresponding width 39 or material thickness 38, see Fig. 3, the holding tabs 6th

In the longitudinal direction of the top plate 2 are on the in Fig. 1st visible underside 17 five adhesive strips 51 applied. By means of these adhesive strips, the top sides 18 of the Subplate halves 20, 21 with the underside 17 of the Top plate 2 can be glued. For this purpose, the lower plate halves 20 and 21 can be folded and folded along the double folding groove 19 the bottom 17 of the top 2 can be created.

Such glued together lower plate halves 20, 21 and Top plate 2 are in Fig. 2 in a bottom view of the shown carrier 1 according to the invention. Same reference numbers identify the same parts and are only partially mentioned.

2 are still in their Starting position 4 arranged according to FIG. 1. Lies accordingly the corresponding passage openings 8 in the top plate 2 opposite and from below on the locking projections 10, 11. Similarly, the respective insertion slots 40 and 41 are the Bottom plate 3 in register with insertion slots 26 and 27 in the top plate 2. Due to the lower Dimensions of the insertion slots 26 and 27 with a Part of their border in the insertion slots 40 and 41 visible.

In Fig. 2, the bottom 44 is the from Subplate halves 20, 21 composite subplate 3 or the underside of the carrier 1 visible. How to recognize is, the passage openings 8 are larger than that Retaining tabs 6, the groove 28 of the retaining tabs in the Holding opening 7 is arranged and except for the locking projections 10, 11 an approximately constant distance between the passage opening 8 and retaining tab 6 is present.

The two abutting edges 24 and 25 of the two halves of the lower plate 20, 21 are roughly in contact with each other. The butt edges run complementary to each other and have similar abutting edge sections 52, 53, 54, 55, 56 and 57 on. Overall, there is an approximately polygonal course for the butt edges, two due to the polygon different sides with respect to a central axis 59 arranged edge points of the shorter sides of the rectangle 23 are interconnected. The directly the shorter ones Rectangular sides of adjacent abutting edge portions 52 and 57 are offset parallel to one another and to the central axis 59 and run approximately above the second and fourth Adhesive strip 51. At these abutting edge sections 52 and 57 a sloping one closes Butt edge section 53 or 56. These are essentially collinear and steeper than a diagonal of the rectangular support 1.

Between the two oblique butt edge portions 53 and 56 two further abutting edge sections 54 and 55 are arranged, that are connected. The one on the butt edge section 53 adjoining edge section 54 runs parallel to Butt edge section 52 and is opposite to this in the direction Longitudinal central axis 59 offset in parallel. The last Butt edge portion 55 extends between Butt edge portion 56 and butt edge portion 54 and extends perpendicular to the central axis 59.

The different abutting edge sections 52, 53, 54, 55, 56, 57 are placed so that none of the retaining tabs 6, Through openings 8 or insertion slots 26, 27, 40, 41 in Upper or lower plate 2, 3 is cut.

In Fig. 3 is a pivoting device 42 for simultaneous Swiveling all retaining tabs 6 from Fig. 2 in their Position 5 shown. The pivoting device 42 is made of a flat and rectangular base plate 48 and a number of them protruding vertically upwards Stamp 43 formed. The number and arrangement of stamps 43 corresponds to the number and arrangement of the retaining tabs 6 and through openings 8 according to FIG. 2. A cross section 46 of each stamp 43 is smaller in size as a corresponding outline 45 of the passage openings 8.

The flat carrier 1 is in the upper part of FIG. 3 shown, in which only one transverse row of shown in use position 5 holding tabs 6 shown is. These are by contact and pressing on the stamp 43 with stamp tips 48 along the pivot path 9 from it Starting position 4, see Figures 1 and 2, in their Use position 5 pivoted. The stand accordingly Holding tabs 6 from the holding openings 7 via an upper side 58 of the wearer and are in their position of use the locking projections 10, 11, see also Fig. 1, held. The Pivot path 9 corresponds essentially to a pivot angle of 90 °, so that the retaining tabs 6 in the use position 5 in are arranged approximately perpendicular to the top 58.
