Description

The invention relates to a presentation device according to the introductory part of claim 1.

Such and similar presentation devices are used Presentation or demonstration of documents, such as posters, Promotional materials, graphics, photographs, etc., used a paper, a canvas, a film or the like. Presentation support between the base and the top of the Stand is kept excited. The flexible stand will be there bent out using its elasticity to the To keep presentation carriers excited. The presentation medium can be provided with appropriate imprints directly, it can however also a sheet or foil-shaped presentation medium on which documents, such as photographs, etc., are available mentioned above.

In FR 2 754 929 A there is a presentation device disclosed, of which in the introductory part of claim 1 State of the art is assumed. At this Presentation device is a single central stand rod provided that is put together from individual rods. Through the elastic bending of the rod elements and thus the stand a tension in this known presentation device achieved for the presentation carrier, so that this excited is held without a separate spring, such as in Combination with a sheeter would be required. The individual rod stands bring this tension approximately in the middle of the presentation medium. The base consists of a Frame made of composite rods.

From AT 1 857 U or the corresponding WO 97/14 132 A is known a presentation device that consists of a Kit consists of elements to be plugged together, so that these Presentation device in a disassembled state in one comparatively small compact packaging can be accommodated can. Specifically, there is one of two side parts and one Cross section of pluggable base provided, and the stand is made up of X-shaped rods. It has shown that this known presentation device on the one hand is relatively unstable when set up, and that on the other hand, the assembly of the presentation device components overall is relatively time consuming and tedious.

DE 93 01 769 U, on the other hand, is one Presentation device known in which the base consists of two Side panels are made by two screwed to them Cross bars are connected; with this base two become relative long, one - piece rods connected by insertion, so that the Stand to form, being between the top ends of the rods and the base of the presentation support strained on ropes is held. The rods are approximately in the middle of their length connected to each other by a cross strut, which with the help of Rings and clamping screws on the rods is fixed.

As can be seen, this presentation device is quite complex when setting up or dismantling, especially there a tool must be used for this; moreover is due to The length of the stand poles is also a compact little one Packaging for transport purposes not possible.

The aim of the invention is now a presentation device of the type mentioned at the outset, with extraordinary in a few simple steps and without the use of tools can be assembled or disassembled, the thereby nonetheless in a compact, small package in the disassembled state can be accommodated, and the above in addition, when assembled, high stability or Stability.

The invention provides a solution to this problem Presentation device with the specified in claim 1 Features before. Advantageous embodiments and further developments are specified in the subclaims. By using the Two cross struts provided double H structure will be high Stability of the stand achieved even when this double H stand from relatively short single bars over multiple Plug connections is assembled. For assembly it is it is particularly cheap if the first on the base lowest individual rods by inserting them into the corresponding open took place, after which the first, lower cross strut put on and then the next, middle longitudinal bars to be assembled. Regardless, the top single or Longitudinal rods over the holding device with the upper end of the presentation support, and at the lower ends the top cross strut is attached to this top bar; this cross strut then has a stabilizing effect when the Unit with the top bars and the presentation support the middle rods, so this part of the assembly too extremely easy and quick to accomplish can be. For the stand in particular can also short rod elements, e.g. with lengths of 50cm or 75cm, the Can be plugged lengthways to stand heights of, for example To achieve 1.5m or even over 2m; the bar length can of course also be shorter or longer, and in particular, e.g. 1m long bar elements used become.

The bars can have a full cross section, it However, tubular rods can also be used, as is per se is preferred. In principle, they can also telescope into one another arranged tubular rods are used, but are preferred identical rods, in particular with the same lengths, are used, which are plugged together using connector elements can.

To the individual components of the stand in the sense of special rigid structure of the same against displacement secure, it has also proven to be advantageous if the Cross struts at their ends with T-pieces for inserting Stand rods are provided.

In a corresponding manner, it is advantageous if on one upper crossbar of the holding device T-pieces with their crossbars are pushed, with holes in their legs for Inserting the upper stand rods are provided.

It has been found for a stable hold of the stand on the base also proven to be advantageous if the stand rods in insertion receptacles an elongated cross member of the base can be inserted or inserted. For manufacturing reasons it is also cheap if the plug-in recordings in separate Plug inserts are provided. The plug inserts can already in corresponding recesses in the cross member or be preassembled in its end parts, for example by simply plugging it in in these recesses, with a tight fit or a Press fit can be provided. An adjustment can also be made different bar cross sections by using different Plug inserts are made without changes to the rest of the base itself would be made so that fewer or smaller different Components, for different sizes of presentation device, manufactured and kept in stock have to.

For a high stability of the stand after assembly it is also an advantage if the plug-in receptacles are inclined Bores are formed, the axes of which are each perpendicular in one plane run to the longitudinal axis of the cross member. It should be mentioned that the parallel rods according to the presentation device the aforementioned DE 93 01 769 U in tubes on the side parts of the base are plugged in, in immediate Neighboring the fastening points of tension cables for the Presentation support at the front end of the base. In the case of the invention Presentation device in the latter Embodiment, however, is the point of attack of the stand Relocated towards the center of the base because the crossbeam usually will be in the middle of the base, creating an additional Increased stability and stability of the stand can be achieved.

For certain applications it is advantageous if the Stand in the use position with lower bars on the Base is placed, which extend vertically upwards. This is the case with comparatively low stands and a slight elastic deflection of the stand structure conceivable when attaching the presentation support. Accordingly, it is cheap here if the plug-in recordings through to the longitudinal axis vertical holes are formed in the cross member.

A particularly advantageous training with a double arrangement back to back of presentation media can be achieved be when at the top ends of the plug-in receptacle inserted stand-rods combined T-Y pieces attached are, which are each provided with two upper blind holes to a pair of additional stand rods for the realization of to accommodate two double H-column structures. In this embodiment thus divides the stand structure above the combined T-Y pieces on so that two double H structures are obtained, however, the lower ones, which are inserted into the base Rods as well as the first, lower cross rod, which is the connects the two combined T-Y pieces, have them together.

To achieve a stable, quickly mountable base it is also advantageous here if at least on the cross member two, preferably four elongated folding feet are hinged, the from a folded rest position parallel to the cross member in an operating position at least substantially at right angles are pivotable to the cross member and back. With this presentation device is therefore a pre-assembled base provided that in the rest position of its folding feet when this are folded against the cross member, nonetheless only a little Space within the packaging is required, but with the unfolded Folding feet provide high stability and stability enables because of the articulated connections between the folding feet and the cross member a high stability and strength of the Can guarantee connection. The installation of the The base by unfolding the folding feet in no time accomplish. The rods forming the stand can then just plug it in.

The folding feet are on the cross member as far out as possible, i.e. at the ends, articulated, and as mentioned are preferred four folding feet attached, two each There are folding feet on one long side of the cross member so that an I-shape with the crossbeam when the base is open as I-longitudinal leg and the folding feet taken together in pairs as I-crossbars is obtained. if desired can the folding feet over more than 90 °, about 100 ° or 110 °, pivoted from the rest position into the extended position be, so with the ends of the folding feet larger spread, for a higher stability about relatively short cross members.

The articulated connection between the folding feet and the cross member can be stiff in itself, so the folding feet in the extended position as well as in the folded position Position remain relatively stable, and with the folding feet only be pivoted while overcoming the friction in the joints can. Since this can be tedious at times, it has turned out to be special proved favorable if the folding feet at least in the unfolded operating position, preferably also in the folded Rest position, are noticeable. To determine the Folding feet can be conventional means such as insertable Pins, but also spring clips, etc., are used. One of manufacturing as well as easy to use results, however, if the folding feet along Hinge pins are adjustable in height relative to the cross member, wherein at an altitude relative to the cross member, e.g. in a lowered position, freely swiveling and at a different altitude, e.g. a position raised in relation to the cross member, by resting on a stop of the cross member in her position. The stop of the cross member can each be suitable, for example, by a Shaped hinge plate to be formed on the respective Folding foot with a heel or shoulder comes to rest. If the folding feet are adjustable in height relative to the cross member are locked by this height adjustment in the respective folding position by creating the e.g. flat shoulder on e.g. flat stop surface be achieved, whereas in the other relative altitude Shoulder and stop are at different levels so that the pivoting movement of the folding feet relative to the cross member is possible is.

To despite the possibility of height adjustment of the folding feet to ensure a firm articulation, it is advantageous if the pivot pin in the link plate of the cross member in one Press fit are attached. This way, only the - limited - Height adjustment of the folding feet and their pivoting possible relative to the pivot pin and the cross member.

For a stable articulation, if necessary with the Possibility of easy height adjustment of the folding feet relative to the cross member, it is also advantageous if each folding foot has several articulated brackets arranged one above the other has and on the cross member associated link plates one above the other are arranged, the hinged tabs of the folding foot and the Intermesh crossbeam.

For manufacturing reasons, it has also proven to be cheap proven if the cross member with a square profile pushed-on hollow profile end parts, which carry hinge plates, is formed. At least the hollow profile end parts can are manufactured as plastic injection molded parts, so that despite the elements necessary for the articulation inexpensive manufacturing is ensured.

It is also an advantage if two are connected to one Longitudinal side of the cross member provided folding feet on their Top hook for hanging a lower crossbar Holding device are provided. If the folding feet with sloping tops are formed at the outer ends thereof, can the hooks - which are at a distance from the joints - be provided such that the Folding feet do not protrude over the top of the cross member, see above that the compact unit of the base for Packaging purposes is preserved.

In the present presentation device results an advantageous further training in that the for intended to hold the respective presentation medium, protruding top and bottom cross bars adjacent the Presentation devices simply through suitable connectors can be connected. This allows two or more presentation devices placed side by side and connected to each other so that a total of one compound, enlarged presentation area by the individual presentation medium is achieved. This presentation space can be done by coupling the presentation devices be designed uniformly, since the coupling is practically in the Level of the individual presentation media takes place so that the individual presentation media in one and the same Level, the presentation area. Accordingly an advantageous development of the present presentation device characterized by connectors with axial aligned blind holes for connecting upper and / or lower crossbars of two double H structure stands placed side by side. It is for ensuring the uniform overall presentation area by the Presentation carrier is formed, moreover, if the Presentation supports on the two double H structure stands their mutually adjacent longitudinal edges detachable with one another, e.g. are connected by means of Velcro fasteners.

In the same way, the invention comprises a presentation device in the unmounted state, as a set of components, such as also a presentation device in the assembled state.

In the presentation device 1 according to Fig.1 and 2 is a stand generally designated 2 as an elastic flexible actual supporting structure provided. This stand is 2 constructed from upright individual bars 3, for example 2 x 3 rods 3, which are identical to each other and preferred Pipe rods, but possibly also rods with a full cross-section are. These rods 3, e.g. made of carbon fiber reinforced plastic or made of aluminum, are relaxed State straight, cf. also Fig.14, and they are assembled Stand support structure connected by two cross struts 4, so that a kind of double H structure arises, like except can also be seen from Fig.1 from Fig.15. The bars 3 as well Cross struts 4 are releasable to one another via plug connections connect or connected, as below with reference to Fig.12 to 15 will be explained in more detail.

The stand 2 is supported in the assembled state a base 5 on the floor, the two lower individual rods 3 of the double H stand 2 in corresponding shots of the Socket 5 are easy to insert, as shown below using the Fig. 6,9 and 15 will be explained in more detail.

Finally, there is also a general presentation 6 designated flexible element, such as a poster, a Foil, a canvas or the like. Provided, the upper and the lower margin at 7 or 8 (see also Fig. 14) is turned over, around there cross bars 9 or 10 as a holding or connecting device for fixing the presentation support 6 at the upper end of the stand 2 or on the base 5. at this attachment of the presentation support 6 becomes the stand 2 elastically bent out, as can be seen from Fig.1 and 2, whereupon the presentation support 6 excited in this operating situation is held.

The base 5 consists, as in FIG. 1, in particular of 3 to 5 can be seen from a cross member 11 the end parts 12 and 13 respectively on opposite Longitudinal folding feet 14 to 17 can be swiveled around vertical axes are appropriate, cf. also the arrows 18 in Fig.3 and 4. Die Folding feet 14 to 17 have an elevation, as shown in Fig. 5 to 7 is a generally triangular shape, but are in Top view elongated, and at their outer free ends they are provided with foot projections 19 to be placed on the ground. Two attached on one long side of the cross member 11 Folding feet, namely the folding feet shown in Fig. 3 and 4 above 14, 15 (cf. also the view in FIG. 5), are at their sloping top with hook 20, which in the folded Condition of the folding feet 14, 15, see Fig. 5, not over the top of the cross member 11 protrude, so that both laterally and up and down in the folded state of the 3 a compact, small unit is achieved, which together with the other elements of the kit of Presentation device, see Fig. 14, in a small packaging can be accommodated; it should also be noted that the Presentation carrier 6 of course for packaging in is rolled up in the usual way.

In the unfolded state of the folding feet 14 to 17, see Fig. 4, however, there will be a large footprint - with the outer, free ones Ends and the existing foot projections 19 - defined, so that a high level of stability of the presentation device 1 in installed state is ensured according to Fig.1.

As can be seen from Fig. 5 and also from Figs. 6 and 7 is, are the joints over which the folding feet 14 to 17 on the cross member 11 are articulated by interlocking hinge plates 21 (on the folding feet) or 22, 23 (on the end parts 12, 13 of the cross member 11) defined. These link plates 21 to 23 engage in the assembled state, being through in them provided holes 24 and 25, which are then aligned with each other are, pivot pins 26 are inserted. This hinge pin 26 sit in the bores 25 of the link plates 22, 23 of the cross member 11 in a press fit, but they are in the Bores 24 of the hinge plates 21 of the folding feet 14 to 17 with little play added, so these folding feet 14 to 17 um it pivots and also along the height Hinge pin 26 can be adjusted. That is the distance between the hinge plates 21 and 22, 23 of the folding feet 14 to 17 or the cross member 11, i.e. the clear width, approximately dimensioned twice as large as the thickness of the articulated brackets 21 or 22, 23, as shown in particular in FIGS. 6 and 7 evident.

The height adjustment of the folding feet 14 to 17 is provided thus in one height position of the folding feet 14 to 17 relative to Cross member 11, namely in the lower position (see only in Fig.7 partially shown folding foot 14 on the left side) of respective folding foot, for example 14, with one on top Joint strap 21 adjoining the upper shoulder 27 below the top, in plan view rectangular hinge bracket 23 of the cross member 11 can be moved. The remaining hinge plates 21 and 22 are substantially semicircular in plan view. The top rectangular hinge bracket 23 of the cross member forms however, with its vertical side surfaces 28 and 29 in the unfolded or folded position of the respective folding foot 14 to 17, when this folding foot is in is in its raised position in relation to the cross member 11, a stop. As mentioned, the folding foot 14 to 17 to be able to pivot it along the respective pivot pin 26 are moved downward so that the shoulder 22 can be moved below the stops 28, 29, and in the respective end position according to FIGS. 8a and 8b, the folding foot, e.g. 17, can be pushed up again so that it passes through Contact of his shoulder 27 against the stop surface 28 or 29, i.e. is locked. Doing so in these two Positions of the folding feet 14 to 17 hold the same firmly ensured relative to the cross member 11.

Close the folding feet 14 to 17 in the folded position otherwise the folding feet with their then outer long sides, s.Fig.3 and Fig.8b, essentially flush with the hinge plates 23 on the outside, so in the folded position in To avoid projecting parts in the sense of a compact unit.

As can be seen in particular from FIGS. 4 and 6, there is Cross member 11 from a square profile 30, on the front Ends the end parts designed in the form of hollow profile parts 12, 13 pushed on and attached in a press fit. Of course, it would also be possible to use the cross member 11 in one piece with the end parts 12, 13 to manufacture.

The end parts 12, 13 not only carry the link plates as mentioned 23.22, each at their foreheads to either side stand out, they are also provided with recesses 31 into which Insert 32 are used, cf. except Fig. 6 and 7 in particular also FIG. 9, in which such a figure is shown Plug insert 32 is shown. Each of these made of plastic molded plug inserts 32 has an oblique bore 33 for inserting the lower rods 3 of the stand 2 (Fig.1) educated. For manufacturing reasons, to reduce tension when cooling to avoid the plastic material of the insert 32, can also have a corresponding recess on the underside 34 be molded, so that comparable material thicknesses can be found everywhere to achieve. For this reason, the insert 32 also instead of entirely block-shaped with those shown in Fig. 9 upper and lower fitting plates.

The oblique bores 33 run in the assembled state with their axes in a normal plane on the longitudinal axis of the cross member 11, such as in Figure 4 on the right Page is indicated schematically at 35. This will cause the Assemble the presentation device 1 also the axes of the lower rods 3 of the stand 2 in these normal planes 35, and thus the rods 3 are on the two long sides of the stand 2 (not yet bent out) parallel to each other; something similar also applies to the rods 3 that are attached afterwards are also parallel to each other. As already mentioned Cross struts 4 are provided, each between the lower ends of upper bars 3 and the upper ends of lower bars 3 be inserted. With regard to easy assembly and disassembly a plug connection is provided for this connection, using T-pieces 36, one below the other are of the same design, and the appropriate already to the Cross struts 4 can be preassembled, as shown in Fig.12 is. According to Fig. 13, each of these T-pieces 36 is with three blind holes 37, 38 and 39 are formed, the cross strut 4 into the blind bore 37 and the longitudinal rods to be connected 3 are inserted into the blind bores 38 and 39.

Similar tees 40, but with a through hole 41 instead of the blind holes 38.39, are used for the connection of the upper cross bar 9 - in the upper envelope flap 7 of the Presentation support 6 is inserted - with the upper rods 3 of the stand 2 used. The crossbar 9 is by the through hole 41 pushed through, as shown in Fig.10 is, and the upper longitudinal rods 3 of the stand 2 with their upper ends in the blind holes 37 of these T-pieces 40 inserted. To enable this plugging in, the Envelope flap 7 of the presentation support 6 on the corresponding Positions openings 42 are provided, see Fig. 14 through which the Project T-pieces 40 with their thighs 43.

Similarly, are in the lower envelope flaps 8 openings 44 attached through which the hooks 20 on the folding feet 14,15 reach through (and thereby the lower cross bar 10 can grasp), so the presentation support 6 at the bottom Hold on end.

From Fig. 15 it can be seen that when the present Presentation device according to the elements kit Fig. 14 is delivered, first the base 5 by unfolding the folding feet 14 to 17 is set up, see also arrows 18 in Fig. 15. Then the lower longitudinal bars 3 of the stand 2 into the plug-in receptacles formed by the bores 33 Socket 5 inserted, after which the lower cross strut 4 with the T-pieces 36 attached to this lower longitudinal rods 3 becomes; then the middle longitudinal rods 3 in the T-pieces 36 inserted into this lower cross strut 4.

The upper rods 3 of the stand 2 are in the at the top Cross bar 9 previously pushed on T-pieces 40, wherein the cross bar 9 previously in the envelope flap 7 of the presentation medium 6 had been inserted. After inserting the Rods 3 in the T-pieces 40 on these upper rods 3 Upper cross strut 4 attached using the upper T-pieces 36.

The unit thus obtained with the presentation support 6, the upper rods 3 and the upper cross strut 4 is then as Whole on the upper ends of the central longitudinal rods 3 of the Stand 2 plugged in, which is due to the stabilization the two cross struts 4 are extremely simple and unproblematic is.

Finally, the presentation medium 6 with the previous one already inserted in the lower envelope flap 8 crossbar 10 hung on the hook 20 of the folding feet 14, 15 of the base 5, the rods 3 on the visible in Fig.1 and 2 Be bent out elastically. This is the presentation device 1 fully assembled.

When dismantling the presentation device 1 is accordingly proceeded in the reverse order, which is just like the Installation can be done quickly and easily with just a few simple steps.

The individual elements 3,4,5,9,10 as well - rolled up Condition - the presentation support 6 also has roughly corresponding length dimensions so that all of these Items packed in a compact little unit can.

Of course it is also possible, instead of separate pre-assembled T-pieces 36 and 40 for the described Plug connections of the individual rods or cross struts too to provide other connector elements; in particular it would be conceivable, comparable sockets in one piece with the corresponding Elements, such as the cross struts 4 and the upper Cross bar 9 to shape. Similarly, it would also be conceivable to produce the cross member 11 in one piece with the end parts 12, 13, and in particular the plug-in receptacles or Bores 33 also directly in the end parts 12 and 13 - instead as described in the separate plug inserts 32 - provided become. As can also be seen, the base 5 is supported in the opened state only with the outer foot projections 19 on the floor, and the cross member 11 extends in the erected State of the presentation device 1 at a distance above the floor. But it can also be at the bottom of the Cross member 11, e.g. in the middle of the longitudinal extent, a comparable foot projection (not shown) attached in order to obtain an additional support element.

Instead of the height adjustment of the folding feet 14 described to 17 for the determination in the respective folding positions or for the release for pivoting would also be others known locking means conceivable, and in particular it would be possible to make the joint so stiff that solely due to the friction, the folding feet 14 to 17 in each Swivel position remain relatively safe. As alternative Locking means could on the other hand insertable locking pins or the like. As is known per se is and need not be explained further here.

16 to 23 are explained below various other modifications shown for certain Applications, especially with a view to increasing the Presentation space, are particularly advantageous.

16 and 17 is a presentation device shown with a double double H-stand structure 2, in which the inserted into the base 5 lower rods 3 in the shown position of use, when attaching two presentation carriers 6 back to back, aligned vertically. At the upper ends of these lower bars 3 are combined T-Y (or V-) pieces 36 'attached to one hand as above already described to record the lower crossbar 4 and on the other hand insert two middle longitudinal rods 3 each can. Possible forms of these combined T-Y coupling pieces 36 'result in more detail from the following Fig. 19 explained in more detail and also from Fig. 20.

On the middle rods 3 are then already in the each described T-pieces 36 attached, around the upper cross bars 4 and the uppermost longitudinal bars 3 take. These uppermost rods 3 in turn each carry in pairs over the top T-pieces 40 the top cross bars 9 (see Fig. 17), on which the two presentation supports 6 with the help of the folded edge 7 are attached.

At the bottom of the presentation support 6 are in corresponding Way as above with reference to FIGS. 1 to 15 described, cross bars 10 in the folded lower edge area inserted, as described a hook on hook 20 on Socket 5 is done. In contrast to the embodiment according to Fig.1 to 15 are in the embodiment according to FIGS. 16 and 17 at all Folding feet 14, 15, 16, 17 hooks 20 for hanging the lower one Cross bars 10 are provided.
