Description

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

Such presentation systems, also called displays, can be found primarily at exhibitions or trade fairs for presentation from graphic information in particular to primarily flexible information carriers such as paper, cardboard, plastic films, Fabric or fabric panels etc. in large quantities Use. They often serve as room dividers at the same time.

In the prior art there are no shortages of proposals such as such Presentation systems are to be trained. So the reveals generic EP 0 231 447 A1 with a presentation system a flexible presentation section between one upper and a lower tubular rod is attached, each consisting of a plurality of differently trained sections connected by a cable. The Poles are in the assembled state of the presentation system through several elastic at right angles to the bars curved elements braced against each other, creating a Bias is applied to the presentation section and it takes on a flat shape. The lower rod is in the assembled Condition of the presentation system on both sides attached to one foot in the middle. The one on the floor in the The foot resting on the right angle to the lower bar is at the end connected to one end of a telescopic rod, which itself extends vertically from the foot upwards and also at right angles runs to the bottom bar. The other end of the telescopic pole has a mounting section for each outer elastically curved element.

Although it is possible with this prior art, the respective Lighting conditions according to the presentation section tilt by adjusting the length of the telescopic rods, inter alia this adjustment option is a relatively complicated one Structure of the presentation system. There is also the risk that the presentation section during training made of a delicate material such as paper strong bias tears.

DE 89 07 326 U1 describes a device for presentation of curtains, stores, vertical blinds, roller blinds or the like known that has at least two frame frames. Each frame consists of two parallel, vertically extending side sections, a foot section connecting the side sections and one upper connecting section provided between the side sections, the parallel to the foot section or below is arranged at an angle to the side sections. The frame frames are at the top and bottom using spacer elements connected and pivotable relative to each other.

Although this device can due to the pivotable connection between the frames in a different arrangement the frames are set up to each other. On However, the disadvantage of this prior art is that that this device in terms of the size of the frames presented objects not sufficiently flexible is.

DE 90 01 742 U1 also discloses a display panel arrangement with at least two frames, both on their sides have parallel legs, which are connected above and below by a cross member. On Leg of one frame is on one leg of the adjacent one Frame by means of two height-spaced swivel connections connected, each having a gear pair.

This display panel arrangement is also in terms of size the individual frame little flexible. Beyond that is special the formation of the swivel connections is proportionate complex.

A partition is also known from DE 30 26 305 A1, composed of support posts and partition elements is. The partition elements have a rigid partition plate that is surrounded by a frame. The frame is made of four a U-profile having spar ends formed, their abutting Ends attached to each other by means of connecting pieces are. These connecting pieces are designed as elbows, whose legs protrude into the spar ends and with these are on the one hand tense and on the other hand jammed. Hooks are formed on the connecting pieces of the partition elements, by means of which the partition elements in on the support posts attached eyelets can be hung.

According to this prior art, the partition has one stable construction. However, it is suitable due to its weight and the given size of their elements as well as their relative complex assembly only conditionally for flexible use especially fairs. In terms of size and weight The same finally applies to those in DE 85 28 710 U1 disclosed wall, which consists of several by means of coupling elements there are detachably coupled wall elements.

Other similar devices are from the publications FR 2 587 606 A2, US 5 791 391, DE 38 01 772 C2, DE 88 15 358 U1, DE 91 03 993 U1 and DE 31 20 656 C1 are known.

The invention is based on the prior art according to the EP 0 231 447 A1 is based on the object of a simple design To create a presentation system that is as flexible as possible is and can be easily and safely assembled and disassembled.

This object is achieved by the specified in claim 1 Features resolved. Advantageous or expedient further training the invention are the subject of claims 2 to 16.

mindestens einem Paar Pfosten,

einem unteren und einem oberen Querelement, die dem Paar Pfosten zugeordnet sind,

mindestens einem Fußelement, das mit einem der Pfosten verbunden ist, und

einem sich zwischen den Pfosten und den zugeordneten Querelementen erstreckenden, flexiblen Präsentationsabschnitt, der mit seinem oberen Ende an dem oberen Querelement befestigt ist,
die Pfosten und die Querelemente rahmenartig lösbar miteinander verbunden, wobei am unteren Ende des Präsentationsabschnitts ein stabförmiges Spannelement befestigt ist, dessen Enden in Längserstreckungsrichtung der Pfosten relativ zu den Pfosten verschiebbar angeordnet und senkrecht zu den Pfosten formschlüssig an den Pfosten festgelegt sind.

According to the invention are in a presentation system

at least one pair of posts,

a lower and an upper cross member associated with 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 and having its upper end attached to the upper cross member,
the posts and the transverse elements are releasably connected to one another in a frame-like manner, a rod-shaped tensioning element being fastened to the lower end of the presentation section, the ends of which are slidably arranged in the longitudinal direction of extension of the posts relative to the posts and are positively fixed to the posts perpendicular to the posts.

The result is an optically appealing, simple design Presentation system created that due to the detachable Connection between the posts and the cross elements can be assembled and disassembled easily and safely, hardly there is a risk that the presentation section when opening or Dismantling the presentation system is damaged because of the presentation section as a result of along the post sliding arrangement of the clamping element ends not under Prestress must be independent of the presentation section load-bearing frame made of posts and cross elements is assembled or disassembled. In the assembled state of the presentation system clamps the slidable along the posts Clamping element due to its own weight the presentation section, so that there is a smooth, visually appealing Presentation space results. The form-fitting prevents Fixing the ends of the tensioning elements to the posts Vertical post that the lower end of the presentation section due to e.g. Drafts oscillate back and forth and the presentation section may be damaged becomes. Great flexibility of the presentation system according to the invention does not follow solely from the fact that the presentation system due to the detachable connection between the posts and the cross members can be folded such that it has compact dimensions when dismantled and thus can be easily transported to different locations. Rather, the arrangement that can be moved along the posts permits of the tensioning element also meet the respective requirements corresponding extension or shortening of the presentation section, the moreover in the connected state the posts and cross members can be made, i.e. without that entire presentation system would have to be dismantled.

According to the teaching of claim 2, each post consists of at least one tubular element with an annular cross section. This means that the posts are not just attractive Exterior, but also have a low weight, which in the With regard to easy transportation of the presentation system is an advantage. In addition, by varying the number of pipe elements, the length of the posts and thus the level of the presentation system to the respective requirements can be easily changed accordingly, so that in particular in interaction with the sliding arrangement of the Clamping element gives a variety of design options.

The claim 3 provides that the tensioning element on Presentation section attached, preferably massive Has basic body. Here can about the own weight of the Basic body depending on the material of the presentation section for a defined preload of the presentation section be taken care of in particular the danger counter the tearing of the presentation section.

According to claim 4 is at the ends of the base body of the clamping element each have a tubular segment with a circular segment Cross section attached, which the respective end of the clamping element forms what, among other things with regard to the production costs can be rated as cheap because standard parts, i.e. for example sections or segments of standardized pipes can be used that are readily available on the market.

According to the teaching of claim 5, the inner diameter the pipe segments of the clamping element slightly larger than that Outside diameter of the tubular elements of the posts, with the central axes of the pipe segments parallel in a common plane run to each other, with the central axes facing each other Pipe elements essentially coincide and perpendicular to the central axis of the base body of the clamping element stand. Thus, the vertical direction of the presentation system sliding arrangement and the horizontal Directional fixing of the clamping element to the Post guaranteed in a structurally simple manner.

If the clamping element in the longitudinal direction of the post is in frictional engagement with the post, so that the clamping element only with the application of a predetermined force relative to the Post is slidable, as specified in claim 6, can be advantageous beyond the weight of the clamping element a bias is applied to the presentation section be, so that even in windy construction sites for a essential smooth, not bulging presentation area is.

The claim 7 provides that the pipe segments of the Clamping element on the inner circumference each with an elastic Lining, preferably a felt section, to effect the rubbing engagement with the posts. This is about it is not just a simple measure to the frictional engagement to effect. Rather, for example, felt sections advantageous on the pipe segments of the clamping element also provided retrospectively or in the event of repeated wear Easy assembly and disassembly of the presentation system be replaced.

According to claim 8 are at least one, preferably Two system connectors are provided to two adjacent posts To connect pairs of posts by friction, being at two system connectors one at the bottom of the adjacent one Posts and one placed at the top of the adjacent posts is. The provision of system connectors causes on a further increase in the flexibility of the presentation system because the width and arrangement of the presentation system by connecting independent, each from a pair of posts, a lower and an upper cross member as well a presentation section with an associated clamping element existing Units according to the respective requirements can be adjusted. There is an increase in stability of the presentation system possible by arranging the units so be that they enclose an angle less than 180 °. If neighboring posts of independent units above and below be connected by means of system connectors with frictional connection, the neighboring posts can also be easily visually attractive and stable parallel alignment.

Claim 9 provides that the tubular element with respect symmetrical about a plane perpendicular to its central axis is formed and each end has an internal thread section having. On the one hand, this has the advantage that the tubular element is easy to manufacture. On the other hand, there is one non-directional assembly of the tubular element possible, which is the structure of the presentation system.

According to the teaching of claim 10, the contiguous Pipe elements of a post by means of a connecting element seamlessly connected, the connecting element has an externally threaded portion which is in the adjacent Screwed internal thread sections of the corresponding pipe elements is. Due to the seamless connection of the pipe elements is a problem-free sliding along the tensioning element the entire length of the posts possible. Furthermore allows such a connecting element a simple and safe installation or extension according to requirements / Shortening the posts with little effort and especially without the need to use special Tools.

If the connecting element has a centering section, which connects to the external thread section and its Outside diameter is smaller than the outside diameter of the Male thread section, as specified in claim 11, assembly is further simplified because the connecting element not only angularly positioned with respect to the corresponding tubular element must be so that the external thread section of the Connecting element with the internal thread section of the tubular element can engage in screw engagement.

According to claim 12, the connecting element has one Internal thread section for fastening the foot element or of the system connector on the corresponding post. This diminishes therefore the total production costs of the presentation system, because only a few different parts are needed i.e. here the same connecting element not only for connecting the pipe elements, but also for the connection of further Parts, namely the foot element or the system connector used can be. Furthermore, this reduces the risk that errors caused by using wrong parts when building the Presentation system.

Claim 13 provides that the lower and the upper Cross element each have a hollow profile section whose ends each have a tubular section with an annular Cross section is fixed, the central axes of the pipe sections run parallel to each other in a common plane and perpendicular to the central axis of the hollow profile section stand. The cross elements thus have sufficient stability not just an advantageous light weight, but are also inexpensive and easy to manufacture because standard parts, i.e. standardized profiles or pipes are used that are easily available on the market. Furthermore is by the symmetrical design of the transverse elements is an undirected one Assembly possible (no left or right or upper or lower Side of the cross member) what the assembly of the presentation system simplified.

Claims 14 and 15 give advantageous designs which, among other things the detachable frame-like connection of the Serve cross members with the posts. So is according to the claim 14 provided that the foot element or the system connector by means of a screw part with the respective pipe section of the corresponding cross element clamped non-positively is, the screw part with the internal thread portion the connecting element is in screw engagement, which in turn with its external thread section in the Internal thread section of the nearest pipe element of the corresponding post is screwed in and in the respective Pipe section of the corresponding cross member protrudes. On compared to the prior art according to example DE 90 01 742 U1 is structurally simple these features also ensure that no accidental Relative rotation between foot element or system connector on the one hand and the corresponding post on the other hand can, which contributes to the stability of the presentation system. According to claim 15, the upper cross member at an upper, free corner of the presentation system with the nearest pipe element of the corresponding post using a plug connected to a shoulder portion rests on the respective pipe section of the upper cross element, engages tightly with one paragraph and with his End whose outer diameter is slightly smaller than that Inner diameter of the internally threaded section of the tubular element, is inserted into the nearest pipe element. So is it to connect the upper cross member to an outer one Post only necessary, a simple plug in the pipe section of the upper cross member and the corresponding Insert pipe element, no tools is needed.

Finally, according to claim 16 which is preferred rectangular presentation section with diametrical ends with each provided a loop, the one loop of the Inclusion of the upper cross member and the other loop of the Includes the tensioning element. The formation of the loops is easy by sewing or gluing, for example of the turned over presentation section possible. Also wear Loops also to simplify the assembly of the presentation system at, since the upper cross element or the clamping element can only be inserted into the assigned loop got to.

1 to 3 is a presentation system 10 according to one first embodiment shown in the assembled state. The presentation system 10 has a pair of posts 12, a lower one Cross member 14 and an upper cross member 16, the pair Posts 12 are assigned two foot elements 18, each are connected to one of the posts 12, and one between the post 12 and the associated cross members 14, 16 extending, flexible presentation section 20 which with attached its upper end 22 to the upper cross member 16 is. As will be described in more detail below the posts 12 and the transverse elements 14, 16 releasably like a frame connected with each other. Also at the bottom is 24 of the presentation section 20 a rod-shaped clamping element 26 is attached, whose ends 28 in the longitudinal direction of the posts 12 slidably disposed relative to the posts 12 and perpendicular to the posts 12 on the posts 12 are specified, which will be discussed in more detail below becomes.

Each of the posts 12 has at least one tubular element 30 preferably aluminum or an aluminum alloy, which has an annular cross section. In Fig. 12 is the tubular element 30 is shown in a plan view. That on has preferably deburred tubular element 30 deburred an anodized surface and is perpendicular to one its center axis 32 extending plane is symmetrical, so that it can be easily manufactured and an undirected Assembly is possible. At each end the pipe element faces 30 one in relation to the total length of the tubular element 30 short internal thread section 34 (dashed in Fig. 12 shown), the connection of adjacent pipe elements 30 or the attachment of other parts. Exists Post 12 made of a plurality of tubular elements 30, i.e. at least two pipe elements 30, as shown in FIGS. 10 and 11 is shown, there are the adjacent pipe elements 30 with their end faces in a flat arrangement and are by means of a connecting element 36, which in Fig. 13 in A plan view is shown and preferably made of a plastic like polyamide, seamlessly connected. To do this the connecting element 36 has an externally threaded section 38 which, 10 and 11 illustrate, in the neighboring Internally threaded sections 34 of the corresponding tubular elements 30 is screwed in. Closes on the external thread section 38 a cylindrical centering section 40 whose outer diameter is smaller than the outside diameter of the outside thread section 38. Finally, the connecting element 36 another one over the entire length of the connecting element 36 extending internal thread section 42 (dashed in Fig. 13 shown), the attachment of the foot element 18th or a system connector 44 on the corresponding post 12 serves as will be described. In this context it should be noted that FIG. 17 is a plan view Variant 36 'of the connecting element 36 with an external thread section 38 ', centering section 40' and internal thread section 42 '(shown in dashed lines) shows that primarily at the top End 46 such post 12 is used with a further posts 12 connected by the system connector 44 ' are (see in particular Fig. 6 top right), and which are only differs from the connecting element 36 in that that the male thread portion 38 'is shorter so that the connecting element 36 'when the presentation system is assembled 10 faster in the internal thread section 34 of the corresponding Pipe element 30 of the post 12 are screwed in can, i.e. does not have to be screwed in as deep.

22 and 23, the lower cross member 14 is in one Front view or a plan view shown. That is preferable made of steel and powder-coated on its outer surface lower cross member 14 has a hollow profile section 48 with a rectangular outer cross-section, corresponding to it recessed ends 50 each have a tube section 52 fixed flush with an annular cross section, for example is soldered or welded, with the central axes 54 of the pipe sections 52 parallel in a common plane run to each other and perpendicular to the central axis 56 of the Stand hollow section 48, so that the lower cross member 14 with respect to the central axis 56 of the hollow profile section 48 vertical plane is symmetrical. The The inner diameter of the pipe sections 52 is slightly larger than the outer diameter of the male threaded portion 38 of the Connecting element 36.

14 and 15 in a plan view and one Front view shown, preferably made of steel and an upper cross member having a powder-coated outer surface 16 has a hollow profile section 58, but one has an annular cross section. To the corresponding recessed ends 60 of the hollow profile section 58 is in each case fixed a pipe section 62 with an annular cross section, the one on each side in the direction of its central axis 64 protrudes slightly beyond the hollow profile section 58. The central axes 64 which is preferably on the hollow profile section 58 welded or soldered pipe sections 62 run in a common plane parallel to each other and are perpendicular to the central axis 66 of the hollow profile section 58, so that the upper cross member 16 with respect to the central axis 66 of the hollow section 58 vertical plane symmetrical is. The inside diameter of the pipe sections 62 is slightly larger than the external diameter of the external thread section 38 'of the connecting element 36'.

In the following the releasable, frame-like connection of the Post 12 with the lower cross member 14 and the upper cross member 16 described in more detail.

As shown in FIGS. 1 to 3 in particular, the upper cross member 16 at an upper, free corner 68 of the presentation system 10, i.e. 1 to 3 on both sides, with the nearest pipe element 30 of the corresponding post 12 is connected by means of a plug 70 which in FIG. 16 is shown in more detail in a top view. The preferred made of aluminum or an aluminum alloy, one Plug 70 having a powder-coated surface has a cylindrical shoulder portion 72 to which a cylindrical Paragraph 74 of smaller diameter, which in turn over a 45 ° bevel into a chamfered, cylindrical At the end of 76 even smaller diameter passes into the starting from its front, also for weight reasons Blind bore 78 (shown in dashed lines in Fig. 16) introduced can be. As shown in FIG. 3 in particular, corresponds the outside diameter in the direction of the central axis 80 of the plug 70 relatively short shoulder portion 72 substantially the outer diameter of the pipe section 62 of the upper Cross member 16, while the outer diameter of the paragraph 74 slightly smaller than the inside diameter of the pipe section 62 is. Paragraph 74 is in the direction of the central axis 80 of the plug 70 somewhat shorter than the pipe section 62. The Outer diameter of end 76 of plug 70 that is longer than whose paragraph is 74 is finally slightly less than the inner diameter of the female threaded portion 34 of the tubular member 30. The result is the assembled state of the presentation system 10 the shoulder portion 72 of the plug 70 flat on the respective pipe section 62 of the upper cross element 16, while the plug 70 with its shoulder 74 which in turn is flat on the nearest tubular element 30 overlying pipe section 62 engages closely and with his End 76 is inserted into the nearest pipe element 30, so that the central axis 80 of the plug 70 with the central axis 32 of the closest tubular element 30 coincides. In the Figures 1 and 3 are the closest pipe element 30, the Pipe section 62 of the upper cross member 16 and the plug 70 only for the sake of clarity towards the central axis 32 of the tubular element 30 shown slightly spaced.

According to FIGS. 1 and 3 in particular, the lower cross element 14 in the area of a lower, free corner 82 of the presentation system 10, i.e. 1 and 3 on both sides, on the respective lower ends 84 of the corresponding posts 12 below Using the foot element 18 attached. That has in 24 and 25 in a plan view and a front view shown, preferably made of sheet steel and a foot element 18 having a powder-coated surface in the middle an obliquely countersunk through hole 86 (in FIG. 25 shown in dashed lines) for receiving a screw part 88 (for example a countersunk screw), which one accordingly beveled head 90, preferably with a hexagon socket and an adjoining 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 is the elongated one with rounded ends Foot element 18 with the respective tube section 52 of the lower one Cross member 14 clamped non-positively, which is Screw part 88 with the internal thread section 42 of the connecting element 36 is in screw engagement, which in turn with its external thread section 38 into the internal thread section 34 of the closest tubular element 30 of the corresponding one Post 12 is screwed and in the respective Pipe section 52 of the lower cross member 14 protrudes. With others Words are said by the screw engagement described the pipe section 52 of the lower cross member 14 at its End faces between the foot element 18 and the tubular element 30 clamped, the central axes 32, 54 of the tubular element 30 or the pipe section 52 coincide because the pipe section 52 via the external thread section 38 of the Connecting element 36 is centered. It can be seen that in this way the foot element 18 in a certain angular position be set with respect to the lower cross member 14 can. In Figures 1 and 3 are the closest pipe element 30, the tube section 52 of the lower cross member 14 and the foot element 18 only for better clarity for the sake of the central axis 32 of the tubular element 30 shown slightly spaced, actually these parts lie however to each other.

On the so from the post 12 and the lower cross member 14th and the upper cross member 16 composite frame the preferably rectangular one, made of a resilient material, like a natural or synthetic fabric, a film, Paper etc., existing presentation section 20 attached in such a way that the upper end 22 of the presentation section 20th wraps around the hollow profile section 58 of the upper cross member 16 or the upper end 22 of the presentation section 20 is designed as a loop into which the upper cross element 16 is plugged in. The one diametrically opposite the upper end 22 lower end 24 of the presentation section 20 accordingly designed as a loop into which the tensioning element 26 is inserted. 1 and 3 are seams 94 for training the loops are shown in dashed lines. The loops can, however, also by gluing the respective end 22, 24 of the presentation section 20 or by another connection be formed, which also after assembly of the above Framework can be done.

20 and 21 show the clamping element 26 in a plan view or a front view. The preferably made of steel and having a powder coated surface Clamping element 26 has one at the lower end 24 of the presentation section 20 attached as described above, preferably massive base body 96 with a round cross section. On the correspondingly recessed ends 98 of the base body 96 each have a tubular segment with a circular segment Cross-section and a segment angle less than 180 °, which is slightly on each side in the direction of its central axis 100 protrudes over the base body 96 and the respective Forms end 28 of the clamping element 26. The central axes 100 that is preferably welded or soldered to the base body 96 Pipe segments 28 run in a common plane parallel to each other and perpendicular to the central axis 102 of the base body 96. The clamping element 26 is thus related one perpendicular to the central axis 102 of the base body 96 Level symmetrical. The inside diameter of the pipe segments 28 of the clamping element 26 is slightly larger than the outer diameter of the tubular elements 30 of the posts 12, wherein in the assembled state of the clamping element 26, the central axes 100 of the pipe segments 28 with the central axes 32 opposite one another Pipe elements 30 of the pair of posts 12 in essentially coincide, so that the clamping element 26 perpendicular fixed to the posts 12 in a form-fitting manner on the posts 12, arranged in the direction of the posts 12 but slidably is. As a result, the presentation section becomes 20th by the weight of the tensioning element guided on the post 12 26 excited.

In addition, the clamping element 26 in the longitudinal direction the post 12 with the post 12 additionally in frictional engagement stand so that the clamping element 26 only with application a predetermined force relative to the post 12 is. For this purpose, the tube segments 28 of the clamping element 26 on the inner circumference each with an elastic lining (not shown), preferably a felt section, be provided, the frictional engagement with the post 12 causes.

4 to 6 is a second embodiment of the Presentation system 10 shown in the assembled state, with reference to in particular FIGS. 1 to 3 described first embodiment corresponding parts are provided with the same reference numerals and in the following not be described again. The second embodiment differs from the first embodiment in that several pairs of posts 12 are associated with each Cross elements 14, 16, presentation section 20 and clamping element 26 to enlarge the presentation area with each other are connected. 4 to 6 are for clarity only one end of the presentation system 10 for the sake of it and the first connection of two pairs of posts 12 is shown; further pairs of posts 12 can be connected accordingly become. For the positive connection of neighboring Posts 12 of two pairs of posts 12 are shown in FIG Embodiment two system connectors 44, 44 'is provided, one of which 44 at the lower end 84 of the adjacent Posts 12 and a 44 'at the top 46 of the adjacent one Post 12 is arranged. 28 and 29 as well 18 and 19 show the system connectors 44, 44 'in a top view or a front view. Which are only in their System connector 44, 44 'differing in external dimensions preferably made of a steel sheet with powder-coated Surface and point in a symmetrical arrangement each two obliquely countersunk through holes 104, 104 '(in the 29 and 19 shown in dashed lines) for receiving Screw parts 88 on. The connection of the system connector 44, 44 'to the corresponding posts 12 is carried out analogously to that above described connection of the foot elements 18, i.e. under a Screw engagement through the through holes 104, 104 'extending screw parts 88 with in the nearest pipe elements 30 screwed connecting elements 36, 36 ', the pipe sections 52, 62 of the corresponding Cross elements 14, 16 on their end faces between the respective system connector 44, 44 'and the respective Pipe element 30 clamped. This allows adjacent posts 12 reliably connected to each other in an exactly parallel alignment be, it is also possible to neighboring lower cross elements 14 or upper cross elements 16 in a predetermined Fix the angular position to each other.
