Description

PRESENTATION DEVICE Description of the invention The invention relates to a presentation device with a base, with bars, connectable or connected by means of a transverse post, for a flexible platform connectable or connected to the base by means of a plug-type connection, and with a retention means for a presentation carrier, for example a poster, film or the like for the connection of the latter to the base and to the platform. Presentation devices of this type are used for the presentation or visual representation of documents, such as cartels, advertising materials, graphics, photographs etc., a paper, a fabric, a film or such a similar presentation carrier is retained, stressed , between the base and the upper end of the platform. The flexible platform is, in this case, flexed, using its elasticity, in order to keep the presentation device tensioned. The presentation bearer can be provided directly with printed signs This may also take the form of a presentation carrier in the form of a sheet or in the form of a film, to which documents, such as photographs, etc., are fixed, as mentioned above. The document AT 1 857 U of the corresponding document WO 97/14132 A describes a presentation device consisting of an equipment for constructing elements to be connected to each other, so that, in the dismantled state, this presentation device can be accommodated in a compact package, comparatively small. In particular, here, a base capable of being connected together from two lateral parts and a transverse part is provided, and the platform is composed of bars interconnected in an X-shaped manner. It has been shown, on the other hand, that this known presentation device is relatively unstable in the erected state and, on the other hand, it is generally time consuming and it is problematic to plug the components of the display device into each other. On the other hand, the German patent DE 9? 01 769 U describes a presentation device of the type mentioned in the introduction, in which the base consists of two lateral parts that are connected by means of two transverse rods screwed to them; two relatively long one-piece rods are connected to this base when being inserted therein, in order to form with this the platform, the holding carrier being held, tensioned on ropes between the upper ends of the rods and the base. The rods are connected to each other approximately in the middle part of their length by means of a transverse post which is fixed to the rods with the aid of rings and fixing screws. As is clear, this presentation device is somewhat complicated to be erected and disassembled, above all because a tool must also be used for this purpose; In addition, due to the length of the rods of the platform, it is also not possible to have a small, compact package for transport purposes. The object of the invention then is to provide a display device of the type mentioned in the introduction, which can be constructed and disassembled again unusually by medium of few manual actions and without the help of tools, which, at the same time can nevertheless be accommodated in the dismantled state in a small, compact package, and which also has high stability or firmness in the assembled state.

The presentation device according to the invention, of the type mentioned in the introduction, is characterized in that the platform has individual bars, which are plug-in together or joined together, and at least two transverse posts to achieve a structure of double H of the platform. As a result of the double H structure provided with the help of the two transverse poles, high stability of the platform is achieved, even though this double H platform is assembled from relatively short single bars via multiple plug connections. For assembly, it is particularly beneficial, at the same time, if the lower individual bars are first fixed to the base when being inserted into the corresponding receptacles, after which the first lower transverse post is engaged thereon and then assembled the following intermediate longitudinal bars. Notwithstanding jj ^ Éfeg this, the individual or longitudinal bars of the upper part are connected to the upper end of the presentation carrier via the retaining means, and the upper transverse post is coupled to the lower ends of these higher bars; this transverse post subsequently has a stabilizing effect when the unit having the highest bars and the display carrier is coupled onto the intermediate bars, so that even this part of the assembly operation can be carried out in an extremely simple manner and fast In this case, in particular, even the short bar elements, for example with a length of 50 cm or 75 cm, can be connected to each other longitudinally for the platform, in order to achieve the platform heights for example of 1.5 m. even higher than 2 m; however, the length of the bar may of course also be shorter or longer, and, in particular, bar elements having a length of, for example, 1 m may be used. The bars may have a solid cross section, but tubular bars may also be used, as is preferred by 2 ^ g ^ i-fr-pi -n- HE. In principle, tubular rods telescopically accommodated one inside the other can also be used, but preferably identical rods, in particular with equal lengths, are used, which can be connected to one another via pin correction elements. In order to secure the individual components of the platform with the effect of a particularly rigid structure of the latter against displacement, it has also been proven to be advantageous if the transverse posts are provided at their ends with T-pieces for the plug in the support bars. Correspondingly, it is advantageous if the T-pieces are pushed with their transverse nets on an upper transverse bar of the retaining means, the holes for the plug on the upper support bars are provided on the legs of the T-shaped pieces. In addition, a stable retention of the platform on the base has proven to be advantageous, in addition, if the bars of the platform are plugged into or plugged into the plug receptacles of an elongated transverse member of the -------------- i ájj ^^ íjjK base. For manufacturing reasons, it is also beneficial at the same time, if plug receptacles are provided in separate plug inserts. The plug inserts can, in this case, either be pre-assembled in the corresponding recesses in the transverse member or its end portions, for example simply plugged into these recesses, and a narrow fit or press fit can be provided. . At the same time, the adaptation to different bar sections, using different plug inserts, can also be carried out, without changes that have to be made on the rest of the base itself, so that fewer or smaller different components have to be produced and kept in reserve for different sizes of presentation devices. For the high stability of the platform after assembly, it is also advantageous if the plug receptacles are formed by oblique holes, the axes of which in each case run in a plane perpendicular to the longitudinal axis of the transverse member. It can be noted that, according to the German patent DE 93 01 769 U, previously mentioned, the parallel rods of the ----to------------_ Display devices are plugged into tubes on the side portions of the base, specifically in the immediate vicinity of the securing points of the tension ropes for the display carrier at the front end of the base. In contrast, in the embodiment mentioned at the end of the presentation device according to the invention, the coupling point of the platform is moved towards the center of the base, since, as a rule, the transverse member will be present in the middle part of the base, with the result that an additional increase in the firmness and stability of the platform can be achieved. For specific applications, it is advantageous if, in the position of use, the platform is placed on the base by means of lower bars extending vertically in the upward direction. This can be considered, for example, in the case of comparatively low platforms and a light, elastic, outward flexing of the platform structure when the display carrier is fixed. It is therefore beneficial here if the plug receptacles are formed by holes perpendicular to the longitudinal axis of the transverse member. A particularly advantageous design with a double arrangement of back-to-back presentation carriers can be achieved by fitting combined TY parts to the upper ends of the platform bars plugged into the plug receptacle, and each provided with two. higher blind holes, so that in each case they receive a pair of additional support bars to produce the double-H platform structures. In this mode, therefore, the platform structure is divided above the TY parts. combined, to obtain two double H structures which, however, have in common the lower bars connected to the base and the first lower crossbar that connects the two TY parts combined. In order to achieve a stable base capable of being assembled quickly, it is also advantageous here if at least two, preferably four elongated folded feet are hinged on the transverse member and are capable of being pivoted out of a reclined upward position of rest parallel to the transverse member in a operating position at least essentially at right angles to the transverse member and back again. In this presentation device, therefore, a preassembled base is provided which, in the resting position of its collapsible feet, when these are folded against the transverse member, nevertheless requires only a small amount of space within the package , but it makes it possible to have high stability or firmness when the folding feet are folded outwards, since the articulated connections between the folding feet and the transverse member can ensure the high stability and firmness of the connection. In this case, the base can be erected, and the folding feet folded out at the same time, in the shortest possible time. The bars that form the platform can be simply plugged in. The folding legs are articulated on the transverse member as far outwards as possible, ie at their ends, and as mentioned, four folding legs are preferably fixed together, in each case two folding legs are present on a longitudinal side of the member transverse so that, when the base is in the unfolded state, a shape is obtained of I, with the transverse member as the longitudinal leg of the I and with the folding legs, taken together in pairs, as the transverse lines of I. If desired, the folding legs can also be pivoted out of the rest position towards the position deployed by more than 90 °, for example from 100 to 110 °, thereby obtaining a greater expansion for greater stability, for example in the case of relatively short transverse members, by means of the ends of the collapsible feet. The articulated connection between the collapsible feet and the transverse member may be rigid per se, so that the collapsible feet reside in a relatively stable manner in the deployed position and in the upwardly folded position, the collapsible feet being able to be moved in pivot only by the friction in the joints that are overcome. Since this can sometimes be problematic, it has proven to be particularly beneficial if the collapsible feet are insurable at least in the deployed operating position, preferably also in the reclined upward rest position. In this case, the conventional means per se, such as the spikes of ------------- plug, but also the spring retainers etc., can serve to secure the folding feet. However, a possibility that is simple in terms of production and operation, is provided if the collapsible feet are vertically adjustable relative to the transverse member along the joint pins, being freely pivoted in a vertical position relative to each other. to the transverse member, for example in a lowered position, and which are secured in their respective positions in another vertical position, for example a raised position relative to the transverse member, when resting against a stop of the transverse member. The stop of the transverse member can, in this case, be formed, for example, by means of a suitably shaped connecting strip, against which the respective collapsible feet come to rest with a stop or a shoulder. If the collapsible feet are vertically adjustable relative to the transverse member, therefore, by means of this vertical adjustment, the interlocking can be achieved in the respective folding position for example by the flat shoulder which is supported for example against the face of flat stop, while in the other vertical position •-__-----3-. ^ ggjM relative, the shoulder and the stop lie at different levels, so that the pivoting movement of the collapsible feet relative to the transverse member is possible. In order to ensure a fixed articulated connection despite the possibility of vertical adjustment of the collapsible feet, it is advantageous if the connecting pins are fixed in connecting strips of the transverse member with a snap fit. Only the limited vertical adjustment of the folding feet and their pivoting movement relative to the connecting pins and the transverse member is thus possible. For a stable articulated connection, if appropriate with the possibility of simple vertical adjustment of the folding feet relative to the transverse member, it is also advantageous, in addition, if each folding foot has a plurality of tie strips arranged one above the other and the associated connecting strips are arranged one above the other on the transverse member, the joining strips of the foldable foot and the transverse member engage one another. In addition, for production reasons, it has been proven to be beneficial if the cross member is _. ¿___--. formed by a square profile with end parts of hollow profile of push, which take strips of union. In this case, at least the end portions of the hollow profile can be produced as plastic injection molding, so that cheap manufacture is ensured despite the elements necessary for the articulated connection. It is also advantageous, furthermore, if hooks for suspending a lower transverse bar of the retaining means are provided on the upper side of the two folding feet provided on a longitudinal side of the transverse member. If at the same time the folding feet are formed with the upper sides descending towards their outer ends, the hooks, which are at a distance from the joints, can be provided in such a way that they do not project beyond the upper side of the transverse member when the collapsible feet are in the folded-up state so that, in this respect as well, the compact unit of the base is preserved for packaging purposes. In the present presentation device, an advantageous development is also obtained since the transverse bars in projection, higher and lower than are provided to retain the respective display carrier, and which belong to the adjacent display devices, can be connected to each other in a simple manner by means of suitable connecting pieces. As a result, two or more display devices can be erected side by side and connected to one another, in order to achieve, in general, an enlarged, composite display surface, by means of the individual display carriers. This presentation surface can be made uniform by coupling the display devices, since the coupling takes place virtually in the plane of the individual display carriers so that, in general, the individual display carriers are also present in one and the same plane of the presentation surface. Accordingly, an advantageous development of the present display device is characterized by connecting pieces with axially aligned blind holes, for the connection of the upper and / or lower transverse bars of two double H structure platforms erected side by side. Also, in this mn ^^^ « case, to ensure the uniform complete presentation surface that is formed by the presentation carriers, it is beneficial if the presentation carriers on the two platforms of the double H structure are releasably connected to one another at their mutually adjacent longitudinal edges, for example by means of touch and closure clips. The invention encompasses in the same way a presentation device in the unmounted state, as a team of construction elements, and a presentation device in the assembled state. The invention is explained in more detail below by means of the preferred exemplary embodiments, which are illustrated in the drawings, but to which they are not restricted.

In the presentation device 1 according to figures 1 and 2, a platform, designated generally by the number 2, is provided as an effective, elastically flexible carrying structure. This platform 2 is composed of vertical upright individual bars 3, for example 2 x 3 bars 3, which are identical to each other and are preferably tubular bars, but, if appropriate, also bars with a solid cross section. These rods 3, which consist for example of plastic reinforced with carbon fiber or even aluminum, are in the unstressed state, see also figure 14, and are connected to each other in the carrying structure of the assembled platform , by means of two transverse posts 4, so that a type of double H structure is obtained, as is apparent from Figure 15, as well as from Figure 1. The bars 3 and the transverse posts 4 are to be connected or are releasably connected to each other via connections of plug, as will be explained in more detail later with reference to figures 12 to 15. In the assembled state, platform 2 is supported on the floor via a base 5, the two lower individual bars 3 of platform 2 double H simply have to be plugged into the corresponding receptacles of the base 5, as explained in more detail below with reference to figures 6, 9 and 15. Finally, a flexible element, for example a poster, a film, a fabric or the like, generally designed as a display carrier 6, is also provided, its upper and lower edge being wrapped around 7 and 8 (see also figure 14), so that the crossbars 9 and 10 can be s er pushed therein as a retaining means or connection for fixing the presentation carrier 6 to the upper end of the platform 2 and to the base 5 respectively. When the presentation carrier 6 is fixed from this In this manner, the platform 2 is flexed out elastically, as is evident from FIGS. 1 and 2, after which the display carrier 6 is held in tension in this operating position. As is apparent particularly from Figures 3 to 5, as well as from Figure 1, the base 5 consists of a transverse member 11, to the end portions 12 and 13 of which the collapsible feet 14 to 17 are fixed pivotably around the vertical axes, in each case on longitudinal sides opposite for example also from the arrows 18 in figures 3 and 4. The folding feet 14 to 17 have a generally triangular shape in elevation, as is apparent from the Figures 5 to 7, but, in a top view, are elongated, and their free outer ends, are provided with the foot projections 19 to be placed on the floor. Two folding feet fixed to a longitudinal side of the transverse member 11, specifically the foldable feet 14, 15 evident in the upper part of Figures 3 and 4 (see also the view in Figures 5), are provided on their oblique upper side with hooks 20 that do not project beyond the upper side of the member -_-, ^ ¡^ ^ cross section 11 when the foldable feet 14, 15 are in the folded upward state, see figure 5, so that, when the base 5 is in the folded state together, according to figure 3, a small unit is achieved and compact both laterally and upwards and downwards, and can be accommodated, together with the other elements of the construction equipment of the presentation device, see figure 14, in a small package, it should also be noted that, here, the presentation carrier 6 is of course coiled together in the usual manner per se for packaging. However, when the folding feet 14 to 17 are in the unfolded state, see Figure 4, a large vertical surface, with the free outer ends and the projections 19 present there, is defined, to ensure that the display device 1 has high stability in the erected state according to figure 1. As can be seen from figure 5, and also from figures 6 and 7, the joints, by means of which folding feet 14 to 17 are articulated on the transverse member 11, are defined by connecting strips 21 (on the foldable feet) and 22, 23 (on the end portions 12, 13 of the transverse member 11) which engage one inside the other. In the assembled state, these connecting strips 21 to 23 engage one within the other, the connecting pins 26 are plugged through the holes 24 and 25 provided therein and which are then aligned with one another. These connecting pins 26 are seated in the holes 25 of the connecting strips 22, 23 of the transverse member 11 with a snap fit, but are received in the holes 24 of the connecting strips 21 of the folding feet 14 to 17 with a slight play, so that these collapsible feet 14 to 17 can be rotated about of them and can also be adjusted vertically along these connecting pins 26. For this purpose, the distance between the connecting strips 21 and 22, 23 of the folding feet 14 to 17 and of the transverse member 11, i.e. width cleared, is approximately twice as large as the thickness of the connecting strips 21 or 22, 23, as can be gathered in particular, from the illustration in figures 6 and 7. The vertical adjustment of the folding feet 14 to 17 is provided so that, in one position vertical of the folding feet 14 to 17 relative to the transverse member 11, specifically in the lower position (see the folding foot 14, illustrated only partially in figure 7, on the left hand side), the respective folding foot, for example 14, can be moved from side to side with an upper shoulder 27 which is attached to the upper tie strip 21, below the upper tie strip 23 of the transverse member 11, said rectangular tie strip being in a top view. The remaining strips 21 and 22 are essentially semicircular in a top view. In contrast, when the respective foldable foot 14 to 17 is in the unfolded or folded upward position, specifically when this foldable foot is in its raised position relative to the transverse member 11, the highest rectangular connecting strip 23 of the transverse member forms with its vertical side faces 28 and 29 a stop. As mentioned, so that the folding feet 14 to 17 can be pivoted, the latter must be moved downwardly along the respective connecting pin 26, so that the shoulder 22 'can be moved further. beyond the bottom of the stops 28, 29, and in the respective extreme position of according to the figures. 8a or 8b, the folding foot, for example 17, can be pushed again, so that it is secured, ie interlocked, by its shoulder 27 which rests "against the stop face 28 or 29. This ensures that, in these two positions of the folding feet 14 to 17, these are held firmly in relation to the transverse member 11. Furthermore, in the folded upward position of the folding feet 14 to 17, the collapsible feet are, with their outer longitudinal sides, see Figures 3 and 8b, adjacent to and essentially level with the connecting strips 23 on the outer side, in order to avoid the protruding parts in the joined and folded position obtaining a compact unit, as can be deduced, in particular from Figures 4 and 6, the transverse member 11 consists of a square profile 30, on the end faces of which the end portions 12, 13 designed in the form of hollow profile parts are pushed and fixed with an adjustable you press. However, it would also be possible, of course, to manufacture the transverse member 11 in one piece with the end portions 12, 13.

As mentioned, the end portions 12, 13 not only carry the connecting strips 22, 23 which in each case project on their end faces to both sides, these are also provided with recesses 31, inside which the inserts are inserted. of cap 32, -see further Figures 6 and 7, particularly also Figure 9, in which a plug insert 32 of this type is shown graphically. Each of these plug inserts 32 injection molded from plastic are designed with an oblique hole 33 for plugging or sealing the lower bars 3 of the platform 2 (Figure 1). For production reasons, in order to avoid stresses during the cooling of the plastic of the plug insert 32, a corresponding recess 34 can also be co-formed on the lower side, in order to achieve comparable material thicknesses in any site. For this reason, the plug insert 32, instead of being completely in the form of a block, is also designed with upper and lower positioning plates that can be seen in Figure 9. In the assembled state, the oblique holes 33 in each case they run with their axes in a plane ig ^ Bg | H | U perpendicular to the longitudinal axis of the transverse member 11, as indicated diagrammatically at 35, for example, on the right hand side of FIG. 4. As a result, when the display device 1 is mounted, the axes of the lower bars of FIG. the platform 2 also runs in these perpendicular planes 35, and the bars 3 on the two longitudinal sides of the platform 2 are therefore parallel to each other (in the state still not flexed outwards); the same also applies similarly to the bars 3 which are subsequently coupled and which are likewise parallel to each other. As already mentioned, the transverse posts 4 are provided, which in each case are inserted between the lower ends of the upper bars 3 and the upper ends of the lower bars 3. With a view to facilitating the assembly and disassembly, a plug connection or plug for this connection, the pieces T 36 are used, which are designed identically to each other and which can expeditiously be preassembled on the transverse posts 4, as is evident from figure 12. according to figure 13, each of these T-shaped parts 36 are designed with three blind holes 37, 38 and 39, the transverse post 4 is pushed into the blind hole 37 and the longitudinal bars 3 to be connected are pushed into the blind holes 38 and 39. The similar T pieces 40, but with a continuous hole 41 instead of the blind holes 38, 39 are used to connect the upper transverse bar 9 which is pushed into the fully wrapped, upper tab 7 of the display carrier 6. , towards the upper bars 3 of the platform 2. In this case, the transverse bar 9 is pushed through the continuous hole 41, as is evident from FIG. 10, and the upper longitudinal bars 3 of the platform 2 are inserted. with its upper ends inside the blind holes 37 of these T-shaped pieces 40. In order to make the plug possible in this way, the holes 42, see figure 14, are provided in the tongue 7 of In the corresponding positions, the T-shaped parts 40 project with their legs 43 through said holes.

Correspondingly, the orifices 44 are made in the lower wrapping tongues 8, through whose holes the hooks 20 can be coupled on the folding legs 14, 15 (and at the same time be coupled around the lower transverse bar 10), in order of retaining with this the display carrier 6 firmly at the lower end. It is apparent from FIG. 15 that, when the present display device, which is distributed as the element construction equipment according to FIG. 14, is erected, first the base 5 is erected, with the folding feet 14 to 17 which are displayed at the same time, see also the arrows 18 in Figure 15. Subsequently, the lower longitudinal bars 3 of the platform 2 are plugged into the socket receptacles of the base 5 which are formed by the holes 33, after which the lower transverse post 4, with the T-shaped parts 36 on it, is coupled to these lower longitudinal bars 3, the intermediate longitudinal bars 3 are then plugged into the T-shaped parts 36 on this transverse post lower 4.

The upper bars 3 of the platform 2 are plugged into the T-shaped pieces 40 previously pushed on the upper transverse bar 9, the trisverse bar 9 which has already been pushed previously into the wrapping tabs 7 of the display carrier 6. After the bars 3 have been plugged into the T-shaped parts 40, the upper transverse post 4 is fixed to these upper bars 3 with the help of the upper part 36 in the form of a T. The unit obtained in this way having the presentation carrier 6, the upper bars 3 and the upper transverse post 4, is then coupled as a whole on the upper ends of the intermediate longitudinal bars 3 of the platform 2, this being extremely simple and not presenting problems due to the stabilization by the two transverse posts 4. Finally, the presentation carrier 6 is suspended on the hooks 20 of the folded feet 14, 15 of the base 5 by means of the transverse bar 10 already previously pushed into the lower wrapping tongue 8, the rods 3 are flexed out elastically in the manner aaa »- - evident in figures 1 and 2. The display device 1 is thus already assembled. When the presentation device 1 is disassembled, the corresponding procedure is carried out in the reverse order and, in exactly the same way as the assembly, this can be carried out quickly and simply with only a few manual actions. The individual elements 3, 4, 5, 9, 10 and in the coiled state, also the display carrier 6 have longitudinal dimensions corresponding to each other so that all these elements can be packaged in a compact small unit. It is of course also possible to provide other plug correction elements instead of the pre-assembled, separate pre-assembled pieces 36 and 40 for the above-described plug connections of the individual bars and the transverse posts; in particular, it would be conceivable to form comparable plug bushings in one piece with the corresponding elements, for example the transverse posts 4 or the upper transverse bar 9. It could also be conceivable, in a similar manner, to produce the transverse member 11 in one piece with the end portions 12, 13 and in particular, the receptacles or plug holes 33 can also be provided directly on the end portions 12 and 13, rather than on the separate plug inserts 32, as It is described. As is also clear, in the unfolded state, the base 15 is supported on the floor only with the outer foot projections 19 and, when the display device 1 is in the erected state, the cross member 11 runs at a distance above from the floor. A comparable standing projection (not illustrated) can, however, also be fixed to the lower part of the transverse member 11, for example in the intermediate part of the longitudinal extension of the latter, in order to obtain thereby an element of additional support Instead of the previously described vertical adjustment of the folding feet 14 to 17 to be secured at the respective folding positions or to be released for pivoting movement, other securing means known per se could also be conceivable and, in particular, could be possible make the articulated connection rigid in such a way that the folding feet 14 to 17 remain relatively reliably in the respective pivot position solely due to friction. On the other hand, thrust securing pins or the like could be provided as alternative securing means, as is known per se and need not be explained in more detail here. Figures 16 to 23, also explained below, show various other modifications that are particularly advantageous for specific applications, particularly with a view to increasing the display surface. Thus, Figures 16 and 17 show a display device with a double-H, double platform structure 2, in which, in the position of use shown, when two display carriers 6 are fixed back to back, the bottom bars 3 plugged into the base 5 are oriented vertically. The combined TY (or V) parts 36 'are coupled to the upper ends of these lower bars 3, so that, on the one hand, as already described above, the lower transverse bar 4 can be received and, on the other hand , in each case two Intermediate longitudinal bars 3 can be plugged in. The possible shapes of these combined coupling pieces 36 'of T-Y- can be observed in more detail; from Figure 19 and Figure 20 explained in more detail below. The T-shaped parts 36 are then in each case coupled to the intermediate bars 3 in the manner already described above, in order to receive the upper transverse bars 4 and the upper longitudinal bars 3. These upper or higher bars 3, in turn, in each case, the upper transverse bars 9 (see figure 17), in which the two presentation carriers 6 are fixed with the aid of an edge, are carried in pairs, via the upper T-shaped part 40. 7 of involvement. As described above with reference to Figures 1 to 15, the cross bars 10 are plugged in the lower wrapping edge region, at the lower end of the display carrier 6 in a corresponding manner, the hooking taking place on the hooks 20 on base 5, as described. In contrast to the modality according to figures 1 to 15, in the modality according to the Figures 16 and 17, the hooks 20 for suspending the lower cross bars 10 are provided on all the folding feet 14, 15, 16, 17. In order to achieve vertical alignment of the lower longitudinal bars 3 of the platform structure of double H, double, according to figures 16 and 17, the plug inserts 32 'inserted in the transverse member 11 of the base 5, specifically within the gaps 31 located there (see figure 7), are provided with vertical holes 33 ', see also figure 18.

Figure 19 shows a version of the piece 36 'combined in T-Y, and it is clear that, together, the four plug-in bushings or blind holes 37', 38 'and 39A, 39B are provided in an elaborate piece of plastic. In this case, in a modification of the T-shaped piece 36 according to FIG. 13, there are two mutually parallel upper plug-in bushings 39A, 39B, which serve to be plugged into the two intermediate longitudinal bars 3 in each case, in order to achieve with this the structure of double H, double, of the platform according to figure 16.

Figure 20 illustrates this connection region of the lower transverse bar 4 and in each case of the two intermediate longitudinal bars 3 by plugging into the combined TY shaped parts 36 'and the coupling to the lower bars 3, showing the 20 shows two coupling parts 136 and 136 'somewhat different, with the upper plug bushings being displaced relative to each other. Figure 21 shows two display devices 1 according to figure 1 erected directly next to each other, the platforms 2 of these display devices 1 are identically designed and carry identical display carriers 6, so that in the position of use shown, two identical height structures are obtained. In order to ensure the uniformity of the entire presentation surface defined by the two presentation carriers 6, even though there are some different joining properties of the bars 3, etc., the transverse bars of the higher part 9 and the bars cross sections of the lower part 10 of the two display devices 1 are coupled by means of simple connecting pieces for example cylindrical with axially aligned blind holes 46, 47, see, in addition to Figure 21, in particular Figures 22 and 23. Figure 22 also diagrammatically illustrates, at various sites 48, that presentation carriers 6 can be connected to each other additionally, for example via the touch-and-close securing tapes (sailboat belts) or via magnetic fastening means, in order to additionally secure the uniform presentation surface. Of course, the connection, instead of being made of individual discrete pieces 48, can also be elaborated on the full height of the two display carriers 6, for example by means of a touch and close fastener. Furthermore, by means of the connecting pieces 45 described, it is possible to couple more than two display devices 1, as shown in Figure 21, depending on the complete, desired display surface. Also, the double platforms according to figures 16 and 17, arranged next to one another can, of course, also be coupled to each other.
