Presentation system

Description

The present invention relates to a presentation system according to the preamble of claim 1.

Such presentation systems, also called displays, are used primarily at exhibitions or trade fairs to present graphic information in particular on primarily flexible information carriers such as paper, cardboard, plastic films, fabric or material strips, etc. in large quantities. They often also serve as room dividers.

There is no shortage of suggestions in the prior art as to how such presentation systems should be designed. For example, the generic EP 0 231 447 A1 discloses a presentation system with a flexible presentation section that is attached between an upper and a lower tubular rod, each of which consists of a plurality of differently designed sections connected by a cable. When the presentation system is assembled, the rods are braced against one another by several elastically bent elements that engage the rods at right angles, whereby a pre-tension is applied to the presentation section and this assumes a flat shape. When the presentation system is assembled, the lower rod is attached to a foot in the middle on both sides. The foot, which rests on the floor at a right angle to the lower rod, is connected at the end to one end of a telescopic rod that extends vertically upwards from the foot and also runs at a right angle to the lower rod. The other end of the telescopic rod has a fastening section for the respective outer elastically bent element.

Although it is possible with this state of the art to tilt the presentation section according to the respective lighting conditions by adjusting the length of the telescopic rods, this adjustment option, among other things, requires a relatively complicated structure of the presentation system. In addition, there is a risk that the presentation section, if made from a sensitive material such as paper, will tear under excessive pre-tension.

From DE 89 07 326 Ul a device for presenting curtains, blinds, vertical blinds, roller blinds or the like is known, which has at least two frames. Each frame consists of two parallel, vertically extending side sections, a foot section connecting the side sections and an upper connecting section provided between the side sections, which is arranged parallel to the foot section or inclined at an angle to the side sections.

The frames are connected at the top and bottom by means of spacers and can be pivoted relative to each other.

Due to the pivoting connection between the frames, this device can be set up in different arrangements of the frames relative to one another. However, a disadvantage of this state of the art is that this device is not sufficiently flexible with regard to the size of the objects presented on the frames.

Furthermore, DE 90 01 742 Ul discloses a display panel arrangement with at least two frames, both of which have legs running parallel to one another on their sides, which are connected at the top and bottom by a cross member. One leg of a frame is connected to one leg of the adjacent

Origon Presentation Systems GmbH ,; .·* _# .; .; ."..··. 334/1

Frame by means of two vertically spaced pivot connections, each with a gear pair.

This display panel arrangement is also not very flexible in terms of the size of the individual frames. In addition, the design of the swivel connections in particular is relatively complex.

From DE 30 26 305 A1, a partition wall is also known, which is composed of support posts and partition wall elements. The partition wall elements have a rigid partition plate, which is surrounded by a frame. The frame is made of four U-shaped beam ends, the abutting ends of which are attached to one another by means of connecting pieces. These connecting pieces are designed as angle pieces, the legs of which protrude into the beam ends and are braced to them on the one hand and clamped on the other. Hooks are formed on the connecting pieces of the partition wall elements, by means of which the partition wall elements can be hung in eyelets attached to the support posts.

The partition wall according to this state of the art does have a stable structure. However, due to the weight and the specified size of its elements as well as its relatively complex assembly, it is only suitable to a limited extent for flexible use at trade fairs in particular. With regard to size and weight, the same applies to the wall disclosed in DE 85 28 710 Ul, which consists of several wall elements detachably coupled together using coupling elements.

Based on the prior art according to EP 0 231 447 A1, the invention is based on the task of creating a simply designed presentation system that is as flexible as possible and can be easily and safely assembled and dismantled.

This object is achieved by the features specified in claim 1. Advantageous or expedient further developments of the invention are the subject of claims 2 to 16. 5

According to the invention, in a presentation system with at least one pair of posts,

a lower and an upper cross element assigned to the pair of posts,

at least one foot element connected to one of the posts, and

a flexible presentation section extending between the posts and the associated cross members, which is attached at its upper end to the upper cross member,

the posts and the cross elements are detachably connected to one another in a frame-like manner, with a rod-shaped tensioning element being attached to the lower end of the presentation section, the ends of which are arranged so as to be displaceable relative to the posts in the longitudinal direction of the posts and are fixed to the posts in a form-fitting manner perpendicular to the posts.

The result is a visually appealing, simply designed presentation system that can be easily and safely assembled and dismantled due to the detachable connection between the posts and the cross elements, with little risk of the presentation section being damaged when assembling or dismantling the presentation system because the presentation section does not have to be under pre-tension due to the arrangement of the tension element ends that can be moved along the posts when the frame made of posts and cross elements that supports the presentation section is assembled or dismantled. When the presentation system is assembled, the tension element that can be moved along the posts tensions the presentation section due to its own weight.

Origon Presentation Systems GmbH .:.**. .'· ,1 ·",·"» 334/1

· i

section, so that a smooth, visually appealing presentation surface is created. The form-fitting fastening of the clamping element ends to the posts in a direction perpendicular to the posts prevents the lower end of the presentation section from swinging back and forth due to, for example, drafts, and the presentation section from possibly being damaged in the process. The great flexibility of the presentation system according to the invention is not only due to the fact that the presentation system can be folded up in such a way that it has compact dimensions when dismantled due to the detachable connection between the posts and the cross elements, and can therefore be easily transported to different installation locations. Rather, the arrangement of the clamping element, which can be moved along the posts, also allows the presentation section to be lengthened or shortened as required, which can also be done when the posts and cross elements are connected, i.e. without the entire presentation system having to be dismantled.

According to the teaching of claim 2, each post consists of at least one tubular element with a circular cross-section. The posts therefore not only have an attractive appearance, but are also lightweight, which is an advantage in terms of easy transport of the presentation system. In addition, by varying the number of tubular elements, the length of the posts and thus the height of the presentation system can be easily changed to suit the respective requirements, so that a multitude of design options arise, particularly in conjunction with the movable arrangement of the tensioning element.

Claim 3 provides that the tensioning element has a base body, preferably a solid one, attached to the presentation section. Here, the weight of the

Origon Presentation Systems GmbH _&bgr; · ·· _# j _# j .·*..·*. 334/1

Depending on the material of the presentation section, a defined pre-tension of the presentation section must be ensured in order to counteract the risk of the presentation section tearing. 5

According to protection claim 4, a pipe segment with a circular ring-shaped cross-section is attached to each end of the base body of the clamping element, which forms the respective end of the clamping element, which can be considered favorable in terms of production costs, among other things, because standard parts, i.e. for example sections or segments of standardized pipes, can be used, which are easily available on the market.

According to the teaching of claim 5, the inner diameter of the tube segments of the clamping element is slightly larger than the outer diameter of the tube elements of the posts, with the center axes of the tube segments running parallel to one another in a common plane, essentially coinciding with the center axes of opposing tube elements and standing perpendicular to the center axis of the base body of the clamping element. This ensures that the arrangement of the presentation system can be moved vertically and that the clamping element is positively attached to the posts in a horizontal direction in a structurally simple manner.

If the tensioning element is in frictional engagement with the posts in the longitudinal direction of the posts, so that the tensioning element can only be moved relative to the posts by applying a predetermined force, as stated in claim 6, a pre-tension can advantageously be applied to the presentation section beyond the tensioning element's own weight, so that a substantially smooth, non-bulging presentation surface is ensured even in windy installation locations.

Origon Presentation Systems GmbH „j .··. .; ,: ,**..*·. 334/1

Claim 7 provides that the pipe segments of the tensioning element are each provided with an elastic lining, preferably a felt section, on the inner circumference in order to bring about frictional engagement with the posts. This is not just a simple measure to bring about frictional engagement. Rather, felt sections can, for example, also be advantageously provided subsequently on the pipe segments of the tensioning element or can simply be replaced in the event of wear as a result of repeated assembly and disassembly of the presentation system.

According to claim 8, at least one, preferably two system connectors are provided to connect adjacent posts of two pairs of posts with a force fit, with two system connectors one being arranged at the lower end of the adjacent posts and one at the upper end of the adjacent posts. The provision of system connectors in itself further increases the flexibility of the presentation system, because the width and arrangement of the presentation system can be adapted to the respective requirements by connecting independent units, each consisting of a pair of posts, a lower and an upper cross element and a presentation section with an associated tensioning element. The stability of the presentation system can be increased by arranging the units so that they enclose an angle of less than 180°. If adjacent posts of independent units are connected at the top and bottom with a force fit using system connectors, the adjacent posts can also easily be brought into a visually appealing and stable parallel alignment.

Claim 9 provides that the tubular element is symmetrical with respect to a plane perpendicular to its central axis.

Origon Presentation Systems GmbH _# j »· _# ,; _# ; .·*.·'*· 334/1

is metric and has an internal thread section at each end. This has the advantage that the pipe element is easy to manufacture. On the other hand, the pipe element can be installed in any direction, which makes it easier to set up the presentation system.

According to the teaching of claim 10, the adjacent pipe elements of a post are connected seamlessly by means of a connecting element, whereby the connecting element has an external thread section that is screwed into the adjacent internal thread sections of the corresponding pipe elements. The seamless connection of the pipe elements enables the tensioning element to be moved easily along the entire length of the posts. In addition, such a connecting element allows simple and safe assembly or extension/shortening of the posts as required with little effort and in particular without the need to use special tools.

If the connecting element has a centering section which adjoins the external thread section and whose outer diameter is smaller than the outer diameter of the external thread section, as specified in claim 11, assembly is further simplified since the connecting element does not first have to be angularly positioned with respect to the corresponding pipe element so that the external thread section of the connecting element can enter into screw engagement with the internal thread section of the pipe element.

According to claim 12, the connecting element has an internal thread section for fastening the base element or the system connector to the corresponding post. This reduces the overall production costs of the presentation system because only a few different parts are required,

Origon Presentation Systems GmbH .!·*'· ·· ·· * **..* 334/1

i.e. the same connecting element can be used not only to connect the pipe elements, but also to connect other parts, namely the base element or the system connector. In addition, this reduces the risk of errors being made by using the wrong parts when setting up the presentation system.

Claim 13 provides that the lower and upper cross-elements each have a hollow profile section, at the ends of which a pipe section with a circular cross-section is attached, with the central axes of the pipe sections running parallel to one another in a common plane and perpendicular to the central axis of the hollow profile section. The cross-elements thus not only have an advantageously low weight while being sufficiently stable, but are also inexpensive and easy to manufacture because standard parts, i.e. standardized profiles or pipes, can be used that are easily available on the market. Furthermore, the symmetrical design of the cross-elements enables non-directional assembly (no left or right or upper or lower side of the cross-element), which simplifies assembly of the presentation system.

Claims 14 and 15 specify advantageous designs which, among other things, serve to detachably connect the cross elements to the posts in a frame-like manner. According to claim 14, the base element or the system connector is clamped to the respective pipe section of the corresponding cross element by means of a screw part, whereby the screw part is in screw engagement with the internal thread section of the connecting element, which in turn is screwed with its external thread section into the internal thread section of the nearest pipe element of the corresponding post and protrudes into the respective pipe section of the corresponding cross element.

Origon Presentation Systems GmbH .!.**'· ·· ·· ;**i*..* 334/1

In a structurally simple manner compared to the state of the art according to, for example, DE 90 01 742 Ul, these features also ensure that no unintentional relative rotation can occur between the base element or system connector on the one hand and the corresponding post on the other, which contributes to the stability of the presentation system. According to protection claim 15, the upper cross element is connected to the nearest pipe element of the corresponding post at an upper, free corner of the presentation system by means of a plug, which rests with a shoulder section on the respective pipe section of the upper cross element, reaches closely through this with a shoulder and is inserted into the nearest pipe element with its end, the outer diameter of which is slightly smaller than the inner diameter of the internal thread section of the pipe element. Thus, to connect the upper cross element to an outer post, it is only necessary to insert a simply designed plug into the pipe section of the upper cross element and the corresponding pipe element, for which no tools are required.

Finally, according to claim 16, the preferably rectangular presentation section is provided with a loop at each diametrical end, with one loop serving to hold the upper cross element and the other loop serving to hold the tensioning element. The loops can be formed in a simple manner, for example by sewing or gluing the folded-over presentation section. In addition, loops also help to simplify the assembly of the presentation system, since the upper cross element or the tensioning element only has to be inserted into the associated loop.

In Figs. 1 to 3, a presentation system 10 according to a first embodiment is shown in the assembled state. The presentation system 10 has a pair of posts 12, a lower cross element 14 and an upper cross element 16, which are assigned to the pair of posts 12, two foot elements 18, each of which is connected to one of the posts 12, and a flexible presentation section 20 extending between the posts 12 and the assigned cross elements 14, which is attached to the upper cross element 16 with its upper end 22. As will be described in more detail below, the posts 12 and the cross elements 14, 16 are detachably connected to one another in a frame-like manner. Furthermore, a rod-shaped tensioning element 26 is attached to the lower end 24 of the presentation section 20, the ends 28 of which are arranged so as to be displaceable relative to the posts 12 in the longitudinal direction of the posts 12 and are fixed to the posts 12 in a form-fitting manner perpendicular to the posts 12, which will be discussed in more detail below.

Each of the posts 12 has at least one tubular element 30 made preferably of aluminum or an aluminum alloy, which has a circular cross-section. In Fig. 12

Origon Presentation Systems GmbH '.**. ·· ·· '**'*** 334/1

the pipe element 30 is shown in a top view. The pipe element 30, which is deburred on its edges, preferably has an anodized surface and is designed symmetrically with respect to a plane running perpendicular to its central axis 32, so that it can be easily manufactured and non-directional assembly is possible. At each end, the pipe element 30 has an internal thread section 34 that is short in relation to the total length of the pipe element 30 (shown in dashed lines in Fig. 12), which serves to connect adjacent pipe elements 30 or to attach further parts. If a post 12 consists of a plurality of pipe elements 30, i.e. at least two pipe elements 30, as shown in Figs. 10 and 11, the adjacent pipe elements 30 are in flat contact with their end faces and are seamlessly connected by means of a connecting element 36, which is shown in Fig. 13 in a top view and is preferably made of a plastic such as polyamide. For this purpose, the connecting element 36 has an external thread section 38 which, as Figs. 10 and 11 illustrate, is screwed into the adjacent internal thread sections 34 of the corresponding pipe elements 30. The external thread section 38 is followed by a cylindrical centering section 40, the outside diameter of which is smaller than the outside diameter of the external thread section 38. Finally, the connecting element 36 also has an internal thread section 42 (shown in dashed lines in Fig. 13) extending over the entire length of the connecting element 36, which serves to attach the foot element 18 or a system connector 44 to the corresponding post 12, as will be described later. In this context, it should be noted that Fig. 17 shows a plan view of a variant 36' of the connecting element 36 with external thread section 38', centering section 40' and internal thread section 42' (shown in dashed lines), which is used primarily at the upper end 4 6 of such posts 12, which are connected to another post 12 by means of the system connector 44'.

Origon Presentation Systems GmbH ^ _# ·* _&phgr; .; .: ·";·..* ^334/1

are (see in particular Fig. 6 top right), and which differs from the connecting element 36 only in that the external thread section 38' is shorter, so that the connecting element 36' can be screwed more quickly into the internal thread section 34 of the corresponding tube element 30 of the post 12 when assembling the presentation system 10, i.e. it does not have to be screwed in as deeply.

In Fig. 22 and 23, the lower cross element 14 is shown in a front view and a top view, respectively. The lower cross element 14, which is preferably made of steel and has a powder-coated outer surface, has a hollow profile section 48 with a rectangular outer cross section, to the correspondingly recessed ends 50 of which a pipe section 52 with a circular cross section is flush-mounted, for example soldered or welded, with the center axes 54 of the pipe sections 52 running parallel to one another in a common plane and perpendicular to the center axis 56 of the hollow profile section 48, so that the lower cross element 14 is symmetrical with respect to a plane perpendicular to the center axis 56 of the hollow profile section 48. The inner diameter of the pipe sections 52 is slightly larger than the outer diameter of the external thread section 38 of the connecting element 36.

The upper cross member 16, which is shown in Figs. 14 and 15 in a top view and a front view, preferably made of steel and has a powder-coated outer surface, also has a hollow profile section 58, which, however, has a circular cross section. A pipe section 62 with a circular cross section is attached to the correspondingly recessed ends 60 of the hollow profile section 58, which protrudes slightly beyond the hollow profile section 58 on each side in the direction of its central axis. The central axes 64 of the pipe sections 62, which are preferably attached to the hollow profile section 58, are each connected to the hollow profile section 58.

Origon Presentation Systems GmbH . .* ; .J .·*..**. 334/1

welded or soldered pipe sections 62 run parallel to one another in a common plane and are perpendicular to the central axis 66 of the hollow profile section 58, so that the upper cross element 16 is symmetrical with respect to a plane perpendicular to the central axis 66 of the hollow profile section 58. The inner diameter of the pipe sections 62 is slightly larger than the outer diameter of the external thread section 38' of the connecting element 36'.

The detachable, frame-like connection of the posts 12 with the lower cross element 14 and the upper cross element 16 is described in more detail below.

As shown in particular in Figs. 1 to 3, the upper cross element 16 is connected to the nearest pipe element 30 of the corresponding post 12 at an upper, free corner 68 of the presentation system 10, i.e. on both sides in Figs. 1 to 3, by means of a plug 70, which is shown in more detail in a plan view in Fig. 16. The plug 70, which is preferably made of aluminum or an aluminum alloy and has a powder-coated surface, has a cylindrical shoulder section 72, to which a cylindrical shoulder 74 of smaller diameter is connected, which in turn merges via a 45° bevel into a chamfered, cylindrical end 76 of even smaller diameter, into which a blind hole 78 (shown in dashed lines in Fig. 16) can be made starting from its front side, also for weight reasons. As shown in particular in Fig. 3, the outer diameter of the shoulder section 72, which is relatively short in the direction of the central axis 80 of the plug 70, corresponds essentially to the outer diameter of the tube section 62 of the upper cross element 16, while the outer diameter of the shoulder 74 is slightly smaller than the inner diameter of the tube section 62. The shoulder 74 is slightly shorter in the direction of the central axis 80 of the plug 70 than the tube section 62. The

Origon Presentation Systems GmbH . ·* · ♦ ."..**. 334/1

The outer diameter of the end 76 of the plug 70, which is longer than its shoulder 74, is ultimately slightly smaller than the inner diameter of the internal thread section 34 of the pipe element 30. As a result, in the assembled state of the presentation system 10, the shoulder section 72 of the plug 70 rests flat on the respective pipe section 62 of the upper cross element 16, while the plug 70 with its shoulder 74 closely reaches through the pipe section 62, which in turn rests flat on the nearest pipe element, and is inserted with its end 76 into the nearest pipe element 30, so that the central axis 80 of the plug 70 coincides with the central axis 32 of the nearest pipe element 30. In Figures 1 and 3, the nearest pipe element 30, the pipe section 62 of the upper cross element 16 and the plug are shown slightly spaced apart in the direction of the central axis 32 of the pipe element 30 for the sake of better clarity.

According to Figs. 1 and 3 in particular, the lower cross element 14 is fastened in the area of a lower, free corner 82 of the presentation system 10, i.e. on both sides in Figs. 1 and 3, to the respective lower ends 84 of the corresponding posts 12 with the aid of the foot element 18. For this purpose, the foot element 18, which is shown in Figs. 24 and 25 in a top view or a front view, preferably made of sheet steel and has a powder-coated surface, has a diagonally countersunk through hole 86 in the middle (shown in dashed lines in the figure) for receiving a screw part 88 (for example a countersunk screw), which has a correspondingly beveled head 90 with preferably a hexagon socket and an adjacent external thread section 92 for screw engagement with the internal thread section 42 of the connecting element 36. By means of the screw part 88, the elongated foot element 18, which is provided with rounded ends, is connected to the respective pipe section 52 of the lower

Origon Presentation Systems GmbH · _# ·· _# .J .: ·*";·*** ^334/1

lower cross element 14 is clamped in a force-fitting manner, with the screw part 88 being in screw engagement with the internal thread section 42 of the connecting element 36, which in turn is screwed with its external thread section 38 into the internal thread section 34 of the nearest pipe element 30 of the corresponding post 12 and protrudes into the respective pipe section 52 of the lower cross element 14. In other words, the described screw engagement clamps the pipe section 52 of the lower cross element 14 at its end faces between the foot element 18 and the pipe element 30, with the center axes 32, 54 of the pipe element 30 and the pipe section 52 coinciding because the pipe section 52 is centered via the external thread section 38 of the connecting element 36. It is clear that in this way the foot element 18 can be fixed in a certain angular position with respect to the lower cross element 14. In Figures 1 and 3, the nearest pipe element 30, the pipe section 52 of the lower cross element 14 and the foot element 18 are shown slightly spaced apart in the direction of the central axis 32 of the pipe element 30 for the sake of better clarity, but in fact these parts lie against one another.

The preferably rectangular presentation section 20, made of a flexible material such as a natural or synthetic fabric, foil, paper, etc., is attached to the frame thus composed of the posts 12 and the lower cross element 14 as well as the upper cross element 16 in such a way that the upper end 22 of the presentation section 20 wraps around the hollow profile section 58 of the upper cross element 16 or the upper end 22 of the presentation section is designed as a loop into which the upper cross element 16 is inserted. The lower end 24 of the presentation section 20, diametrically opposite the upper end 22, is correspondingly designed as a loop into which the tensioning element

Origon Presentation Systems GmbH . ♦* j .; ,**..**. 334/1

26 is inserted. In Fig. 1 and 3, seams 94 for forming the loops are shown in dashed lines. However, the loops can also be formed by gluing the respective end 22, the presentation section 20 or by connecting them in some other way, which can also be done after the frame described above has been assembled.

Figures 20 and 21 show the clamping element 26 in a top view and a front view, respectively. The clamping element 26, which is preferably made of steel and has a powder-coated surface, has a preferably solid base body 96 with a round cross-section, which is attached to the lower end 24 of the presentation section 20 as described above. A pipe segment with a circular ring-shaped cross-section and a segment angle of less than 180° is attached to the correspondingly recessed ends 98 of the base body 96, which protrudes slightly on each side in the direction of its central axis 100 over the base body 96 and forms the respective end 28 of the clamping element 26. The center axes 100 of the pipe segments 28, which are preferably welded or soldered to the base body 96, run in a common plane parallel to one another and are perpendicular to the center axis 102 of the base body 96. The clamping element 26 is thus designed symmetrically with respect to a plane perpendicular to the center axis 102 of the base body 96. The inner diameter of the pipe segments 28 of the clamping element 26 is slightly larger than the outer diameter of the pipe elements 30 of the posts 12, whereby in the assembled state of the clamping element 26 the center axes 100 of the pipe segments 28 essentially coincide with the center axes 32 of opposite pipe elements 30 of the pair of posts 12, so that the clamping element 26 is fixed to the posts 12 in a form-fitting manner perpendicular to the posts 12, but is arranged so as to be displaceable in the direction of the posts 12. As a result, the presentation section 20

Origon Presentation Systems GmbH · ** _# J .; .**..**· 334/1

tensioned by the weight of the tensioning element guided on the post 12 2 6.

In addition, the clamping element 26 can also be in frictional engagement with the posts 12 in the longitudinal direction of the posts 12, so that the clamping element 26 can only be displaced relative to the posts 12 by applying a predetermined force. For this purpose, the tube segments 28 of the clamping element 26 can each be provided on the inner circumference with an elastic lining (not shown), preferably a felt section, which brings about the frictional engagement with the posts 12.

In Figs. 4 to 6, a second embodiment of the presentation system 10 is shown in the assembled state, whereby parts corresponding to the first embodiment described with reference to Figs. 1 to 3 in particular are provided with the same reference numerals and will not be described again below. The second embodiment differs from the first embodiment in that several pairs of posts 12 are connected to each other with associated cross elements 14, 16, presentation section 20 and tensioning element 26 to enlarge the presentation area. In Figs. 4 to 6, for the sake of clarity, only one end of the presentation system and the first connection of two pairs of posts 12 are shown; further pairs of posts 12 can be connected accordingly. For the force-locking connection of adjacent posts 12 of two pairs of posts 12, two system connectors 44, 44' are provided in the illustrated embodiment, one 44 of which is arranged at the lower end 84 of the adjacent posts 12 and one 44' at the upper end 46 of the adjacent posts 12. Figs. 28 and 29 as well as 18 and 19 show the system connectors 44, 44' in a top view and a front view. The only differences in their

Origon Presentation Systems GmbH . «· · j .**..*"· 334/1

The system connectors 44, 44', which differ in external dimensions, are preferably made of a sheet steel with a powder-coated surface and each have two diagonally countersunk through holes 104, 104' (shown in dashed lines in Figs. 29 and 19) in a symmetrical arrangement for receiving screw parts 88. The connection of the system connectors 44, 44' to the corresponding posts 12 is carried out analogously to the connection of the foot elements 18 described above, i.e. under a screw engagement of the screw parts 88 extending through the through holes 104, 104' with connecting elements 36, 36' screwed into the nearest pipe elements 30, the pipe sections 52, 62 of the corresponding cross elements 14, 16 are clamped at their end faces between the respective system connector 44, 44' and the respective pipe element 30. This allows adjacent posts 12 to be reliably connected in an exactly parallel alignment to one another, whereby it is also possible to fix adjacent lower cross elements 14 or upper cross elements 16 in a predetermined angular position to one another. It should be noted in this context that the lower system connectors 44, like the foot elements 18, rest on the base of the presentation system 10 or the floor.

In Figs. 7 to 9, a third embodiment of the presentation system 10 is shown in the assembled state, whereby the parts corresponding to the embodiments described with reference to Figs. 1 to 6 in particular are provided with the same reference numerals and are not described again below. The third embodiment differs from the second embodiment in that a different foot element 18' is provided at the free, lower corners 82 of the presentation system 10, which is shown in Figs. 26 and 27 in a top view and a front view. The foot element 18', which preferably consists of a sheet steel with a powder-coated surface, has

a circular shape in plan view and is provided with a through hole 86' (shown in dashed lines in Fig. 27) in the middle corresponding to the foot element 18 for receiving the screw part 88. The foot element 18' is attached to the outer post 12 in the same way as the foot element 18 described above and is therefore not explained again. This foot element 18', which offers a lower moment support, is used in particular when several pairs of posts 12 are connected to each other with associated cross elements 14, 16, presentation section 20 and tensioning element 26 and the stability of the presentation system 10 is achieved by the fact that adjacent cross elements 14, 16 of at least two pairs of posts 12 enclose an angle of significantly less than 180° in plan view.

Fig. 30 to 35 show, in a basic representation, arrangement or construction variants of the presentation system 10, which each has at least one unit E consisting of a pair of posts 12, a lower cross element 14, an upper cross element 16, a presentation section 20 and a tensioning element 26. Several units E are connected as described above by means of system connectors 44 or 44', whereby the presentation system 10 has foot elements 18 or 18' at the end depending on the installation variant (open installation variants according to Fig. 32, 34 and 35) or the system connectors 44 serve as foot elements (closed installation variants according to Fig. 30, 31 and 33). The great flexibility of the presentation system 10 is evident, whereby the size of the presentation area can also be easily adapted to the respective requirements by extending / shortening the presentation sections 20 (changing the height of the posts 12 by adding / removing tubular elements 30 or by sliding the connection of the tensioning elements 26 to the posts 12).
