Kit for exhibition stands and the like

Boiler stands and exhibition stands, especially in shops, have so far been made of construction parts for the statics and accessories, for example wall elements, lighting elements and the like, pastry together. These accessories are also called the technical expansion a trade fair stand, which also includes the electrical power supply, telephone lines and, if necessary, also includes the water supply for the exhibition stand.

The construction parts for the statics, or statics parts for short, are used to create a conventional exhibition stand built like normal house construction. Then it will again be similar to building a house with the necessary technical expansion. This also includes partitions,

Doors and other non-structural parts. Such exhibition stands

often appear as permanent structures, although they are only of temporary duration. This becomes particularly clear when if they have to be dismantled again after a short time. Because of the more or less massive construction, this leads to the especially with the connecting elements between the individual components so that the static parts are no longer properly separated from each other under the time pressure usually prevailing during dismantling, but the exhibition stand more being demolished or canceled. Then ins special the statics parts usually either at all

no longer or at most after costly repair work reusable. These repair costs are often the same as the costs of building a new exhibition stand.

The known kits for exhibition stands require due to their design and because of it resulting assembly method a considerable amount of time for the construction and then for the dismantling. In addition, there is usually a not inconsiderable amount of time for the repair the structural parts and the technical expansion, if the parts are to be used again later.

In the case of the known kits for exhibition stands, the Supply lines always laid afterwards, either with the help of pipe or cable clamps or in Pipe or cable ducts, which in turn are fastened to the structural parts and to the expansion parts with clamps have to. The junction boxes for the individual energy consumers are also individually attached to the static parts or attached individually to the parts of the other technical expansion. For this purpose, trained specialists are the ones concerned Specialization required, i.e. electrical installations may only be carried out by trained and approved electrical installers be relocated. These installations must each be individually checked and approved by the responsible test centers will. A type test of the technical expansion is not possible because it does not apply to the individual parts of the technical The only thing that matters is its installation and its connection with the supply lines. These The way of installation, its construction and its dismantling also require a lot of time and care. They cause considerable costs, especially in view of the fact that only skilled workers are required to do this can be used.

Exhibition stands, which are usually set up in halls, inevitably require a considerable amount of lighting, to put the exhibition goods in the right light.

This requires a correspondingly large number of lighting units, which are arranged in the most varied of ways 1 and need to be aligned * These lighting fixtures'

are either clamped to the analysis parts or 1

by means of suspension devices on the structural components or the Removal parts suspended and aligned. The electric one The connection of these lighting fixtures must in turn be carried out by specialists, which in turn also includes the laying "

normal structural parts and expansion parts. Supplying the Individual sections of these busbar systems are made again in a conventional manner by laying the the supply lines required for this by specialists. j

Are known kits for exhibition stands the node body and; Have truss rods that are used when building an exhibition stand be screwed together. There are node bodies from steel bars, which by folding to a Polyhedra are shaped, in which at the polyhedron through jj through holes are present in the appropriately shaped and

screw-threaded end sections of the framework f rods are put in and on the other side be screwed in the middle of a nut. These statics parts also require the construction and dismantling of a Hesse

It was a not inconsiderable amount of honing and expenditure of time, because every single connection point is meticulous must be screwed and then loosened again. Here can it can happen that the connecting elements are so jam that the later expansion of the exhibition stand either

is considerably more difficult or, in the worst case, even becomes impossible, so that the components are partially cut to be able to dismantle the booth.

The invention specified in claim 1 has the object based on creating a kit for Hessestände, in which both greater freedom of design for the exhibition stand as well as a lighter and simpler assembly and Disassembly of the booth is possible.

The fact that the connecting elements at the ends of the truss rods and at the node bodies as smooth insertion holes gijRORhiiriet are - and thereby - that these parts are by means

Coupling bodies are connected to each other, their

Coupling heads simply have to be inserted into the insertion holes on the static parts, and that only the hooks on the coupling heads must be activated, i.e. brought from the rest position to the operating position

must be, is the structure of the structural parts of such a Booth very much simplified. The time required for the The construction of such a booth and the subsequent dismantling is considerably shortened. Since the analysis parts have simple and robust connectors are connected to each other is

ZO practically eliminates the risk of damage or even destruction of the individual structural components during dismantling. the Parts can therefore also be restored later without difficulty can be used without the need for complex and costly repair work beforehand. Such a

The exhibition stand is therefore set up in a very short time paid, even if individual parts of the Static parts, such as the coupling body, higher Have manufacturing costs than, for example, simple screw connections in some known kits.

Due to the simple assembly method, it is also possible to use a | already partially or fully set up booth to be changed if this should subsequently prove necessary or desirable. For this, too, the time is

wall considerably less than with the known kits.

In one embodiment of the kit according to claim 2 with circular cylindrical plug-in holes and appropriately designed coupling heads, it is possible to use the truss rods in any direction with the node body connect to. This means that when setting up a trade fair stand, you are not restricted to certain levels or certain orientations Truss rods set in the room. It is also possible to twist the truss rods, for example when on it other parts such as BeleuehtunciBkHrnRr are clamped. When the truss rods in a special configuration with fastening devices and / or plug connections for other parts, in particular for lighting fixtures, are provided, these can be made easier can be set to a different orientation than before.

If the insertion holes on the truss rods and the i

If node bodies have the same diameter, the coupling bodies can be used in any orientation will.

\ 20 In an alternative embodiment of the insertion holes according to

L claim 3 or in the development according to claim 4 is it

Conversely, it is possible to use the truss rods in a certain Orientation to connect with the node bodies in terms of their rotational position, this orientation also in the Load is maintained immovably with a torque. This makes it possible to work on the truss bars too To attach cantilevered expansion parts, which under their weight a possibly considerable torque exercise on the associated truss rod. If, in the further development according to claim 4, the polyhedron surfaces are designed in this way are that the circular cylinder inscribed in them has the same diameter as the circular cylindrical version which has insertion holes, then such truss rods can optionally be connected to the node bodies with coupling bodies are coupled, their coupling heads either also Have polyhedron surfaces and thus a certain orientation ensure or the coupling heads with circular cylindrical

Outside, so that the selection and the assembly method of the truss rods are decided at the place of construction of the exhibition stand or can be modified.

In an embodiment of the kit according to claim 5, the contact surfaces can be produced very easily. Also is thereby the assignment of the parts to each other always in the same way guaranteed.

In an embodiment of the kit according to claim 6 one obtains lattice bars that have a low weight and a combine high rigidity. This makes it easy to set up even large exhibition stands without that Personnel must struggle with high weights of the individual parts and without major transport and storage problems occurring. When forming the framework bars with a C-profile the truss rods can easily be used to connect elements of the clamping elements for the inside Attachment of expansion parts to be attached. By designing the kit according to claim 7, the end caps be manufactured in lightweight construction, i.e. with a very low weight, without the construction principle must be abandoned or modified.

In one embodiment of the kit according to claim 8 is there is a great variety in the construction of a trade fair stand.

In one embodiment of the kit according to claim 9, the hooks can be used as a connecting element within the Place the coupling heads so that they can be joined together of the parts do not interfere and they are only actuated afterwards in order to complete the connection of the joined parts. In a further development of the kit according to claim 10, the transferable connecting forces are doubled and also a symmetrical power transmission is achieved in the plane of the two hooks, the one-sided Avoids loads on the interconnected parts.

By a development of the kit according to claim 11 is created a very simple storage of the hooks, in which the hooks are very strong and robust. aside from that allows this type of formation of the hooks and their storage a relatively easy assembly of these parts too.

An embodiment of the kit according to claim 12 results in a very simply constructed actuating device created, the parts of which can be produced relatively easily and cheaply. It is also an easy one and robust operation of the hooks possible. Due to the length of the actuating arm for itself as well as in relation to the length of the hook shank and a certain design of the cam surface, it is possible to use a

Ii; relatively large power transmission with regard to the adjustment movement of the hook into the operating position, creating a secure connection between the parts to be coupled is guaranteed. In the development of the kit according to claim 13, through the use A very simple operation of the coupling body is achieved by rotary sleeves. It also makes the parts the actuator very easy to manufacture. In one embodiment of the kit according to claim 14, the The safety of the connection of the parts to be coupled is increased in that the rotary sleeves each up to the one of the two rotary stops can be rotated, so that for the operator without increased attention It is immediately noticeable whether the actuating device is either in the rest position or in the operating position is located. The parts of the rotary stops are very easy and cheap to manufacture and assemble. In the alternative embodiment of the Bo'-rate according to claim 15 is also a simple ΒιϊλΆ; inclination of the coupling body enables.

By designing the kit according to claim 16 is a Conceivably simple and inexpensive to manufacture feedback device created, especially when the Spring member is hung on the front sides of the hook lugs. This also has the great advantage that the spring member is easily broken or damaged can be exchanged and that this is also possible with otherwise fully assembled coupling bodies. In the alternative embodiment according to claim 17, the spring member is housed more in the interior of the coupling head and therefore less susceptible to damage.

By an embodiment of the kit according to claim 18 is the actuation of the actuating device facilitates. if the stop pin of the two rotating sleeves and the Securing element are arranged on the handle part so that they are in the rest position of the hook in a plane, i.e. on in a straight line, and vice versa in the operating position of the hooks the stop pins of the rotary sleeves half of the common setting level in relation to the The stop pin is on the handle, then it is with Immediately recognizable at a glance whether the coupling body is in the coupling position or just in the joining position is located. This is a check of the correct structure of a trade fair stand in the shortest possible time with the greatest possible Reliability possible.

In an embodiment of the kit according to claim 19, the hooks and possibly parts of the return device are also protected from damage if a The coupling body falls once on the ground and hits the coupling head first.

In an embodiment of the kit according to claim 20, other static parts such as a cable guy, can be arranged on the Hessestand, whereby the Freedom of design for the Hess stand is increased considerably.

In one embodiment of the kit according to claim 21, the parts of the technical expansion can be attached to the static parts in a very simple and quick manner and can be removed again later. There is the greatest possible freedom of design in terms of arrangement and alignment the expansion parts given. This applies to walls and doors as well as to frame and shelf parts and also to others Parts.

15th

In an embodiment of the kit according to claim 22, greater freedom of design is created for the construction of a Hessestand. This applies in particular to a development of the support columns according to claim 23 by the

Support pillars in relatively close height graduation other

Expansion parts can be arranged easily and simply. In one embodiment of the kit according to claim 24, the Hessestand can be easily and quickly aligned in a vertical direction even on uneven ground. By an award design of the kit according to claim 25 is the attachment other expansion parts on the support pillars are greatly facilitated and simplified. These expansion parts, for example platforms and the like, can be easily opened different swivel positions and at different heights place. The hanging and unhooking of the hanging supports is very easy to do.

An embodiment of the kit according to claim 26 means that practically no supply lines have to be laid freely at the exhibition stand, but rather they

a are largely housed in the framework bars.

'By using the truss rods with integrated

Supply lines, especially the electrical supply lines, and by using the short ones Coupling lines for connecting the supply lines from one truss to another is mainly used the subsequent laying of the supply lines on The fully assembled Hessestand is no longer necessary, as is well known Skilled workers would have to be used. Here it is now possible to supply the exhibition stand at any Place, for example, with the normal mains voltage and / or to effect with Te. Telefonlinien and the like by simply inserting the coupling lines. This is a Considerable savings in working time, especially for skilled workers, and in time for checking and inspecting the exhibition stand. In addition, changes can be made at any time can be carried out in an equally simple and quick manner. In the development of the ßausatzes according to claim 27 can These advantages come into their own because they help in the arrangement and alignment of lighting fixtures is very free. This allows for example the

ZO lighting of individual exhibits also during the course of the exhibition can change slightly if a different arrangement or orientation of the exhibition item proves necessary or desirable and the original lighting is no longer sufficient for this ·., odor it was not sufficiently effective.

The stand 40 shown in Fig. 1 is from a j

larger number of different construction parts for the statics and different parts for the technical structure built. The main parts of the structural parts for the statics, or statics parts for short, are truss rods 41, supporting columns 42 and node body 43 which are connected to one another by means of coupling bodies 44. To the parts for the Technical expansion, or expansion parts for short, include, among other things, clamp holders 45 and suspension supports 46 to the Truss rods 41 and / or can be clamped or hooked onto the support pillars 42 and then further expansion parts can accommodate, such as support rods 47 to which wall elements 48 are attached.

** · ¹³ * ■

At the junction shown in FIG. 2 there are four framework bars 41 arranged in a common horizontal plane and coupled in this plane by means of a coupling body 44 to the node body 43. Below the Node body 43 a vertically aligned truss rod 41 is arranged, which serves as a support for the other parts « Instead of this vertical truss rod 41, a support column 42 can also be imagined.

The node body 43 is a ball made of some light metal or a high strength plastic and _s having a

Toughness. The node body 43 has eight insertion holes 51 each in three meridian planes aligned at right angles to one another, that is to say a total of eighteen insertion holes, which are arranged evenly distributed in the three meridian planes. The circumferential surface 52 of the insertion holes 51 is a smooth circular cylinder surface. On the outside, each insertion hole 51 is surrounded by a flat, annular outer contact surface 53 (FIG. 3). On the inside, the insertion holes 51 are surrounded by a likewise flat, annular contact surface, the inner contact surface 54 (FIG. 4). The outer opening of the insertion holes 51 is provided with a small chamfer 55 which serves as an insertion aid.

25th

If, with this number and arrangement of the insertion holes 51, the insertion holes 51 are made continuous, they e.g. be drilled through, and if, in addition, certain proportions are adhered to, namely the diameter the ball of the nodal body 43 with 120 mm, the diameter the insertion holes 51 with 20 mm, the distance between the outer contact surface 53 and the inner contact surface 54 with 25 mm the outer diameter of the outer contact surface 53 with 40 mm and the outer diameter of the inner contact surface 57 with 27 mm, then in the interior of the spherical nodal body 53 a cavity 56 automatically results (Fig. 4 and 5). If then the inserted holes 51

stuck heads of the coupling body 44 within the cone surface remain, which is indicated in Fig. 5 by the dashed lines 57, then any mutual Obstruction of the coupling body 44 avoided. 5

The truss rods 51 are each formed by a hollow body 61 and two end caps 62, which are generally detachable from one another are connected. The hollow body 61 can be designed as a tube, as shown in FIGS. 5 and 6. This

1Ö hollow body can also have an open profile, for example ^ wise a C-profile that is open over a certain central angle. In this case it is useful if along the edges of the profile parts are present, in which a cover profile can be inserted and / or clamped On the outside, the C-profile is added to a complete tubular profile. The hollow body 61 are both in the execution with a closed circular ring profile as well as with the design with a C-profile generally as light metal pressed steel parts manufactured. For half-timbered members that are not subject to stress, the manufacture of plastic also comes in Consideration. If the diameter of the ball of the node body 43 is 120 mm, the hollow body has a diameter 61 by 100 mm has a particularly good aesthetic effect.

The end caps 62 are also largely hollow. They have an edge or collar part 63 that is circularly cylindrical and the outer diameter of which is equal to the outer diameter of the hollow body 61. The end caps 62 also have a flat, annular base part 64.

The collar part 63 has a reinforcement 65 in the region of its edge, which is offset towards the edge. This shoulder 66 has an outer diameter which is equal to the inner diameter of the hollow body 61, so that there the two

β · a · - * ■ «ail

- 15 -

Parts can overlap one another, as shown in FIG. 6. In the area of this shoulder 66 there are fastening elements 67 which are shown in FIG. 6 as countersunk screws. The fastening elements 67 can, however, also be designed as projections and recesses in the manner of a bayonet lock or bayonet lock, in particular when the hollow body 61 has profile parts on its inside which protrude inward from its cylindrical inner surface 6B and which are caused by the incision of a Circumferential groove can be machined so that they can serve as parts of a Renk ^ closure.

In the middle of the bottom part 64 there is a circular through hole 69 into which a plug-in socket 71 is inserted. is set. The plug-in socket 71 has a sleeve part and a flange part 73. The outside diameter of the The sleeve part 72 is matched to the inside diameter of the through hole 69 in such a way that the plug-in socket 71 is guided on the bottom part 64. The flange part 73 is used for the fixed Connection of the plug-in socket 71 with the end cap 62. The The connecting elements used for this are not shown in FIG. 6. You can use or as fastening screws be designed without a nut or as a rivet. The connection of the plug-in socket 71 with the end cap 62 can also thereby caused that on the outside of the sleeve part 72 a screw thread is attached, on which a nut is screwed on, between which and the flange part 73 the edge region of the through hole 69 is then firmly clamped will.

If the end caps 62 are made as a cast part, in particular as a light metal cast part, the sleeve part surrounding the insertion hole 75 can be molded directly onto the bottom part of the end cap. Then there is no need for a special plug-in socket including the connecting elements between it and the end cap.

In Fig. 5, two of the coupling body 44 are shown in section, of which for better differentiation from the other coupling bodies the one on the left as the coupling body 44.1 and the one on the right located is designated as the coupling body 44.2. Of the Coupling body 44.1 is in the rest position of its parts shown, in which it can be assembled with a truss rod 41 and / or with a node body 43. Of the Coupling body 44.2 is in its operating position Parts shown in the one hand on the node body 43 and on the other hand, is coupled immovably to the truss rod 41 located on the right in the longitudinal direction. In Fig. 6 is the coupling body 44.2 shown again. In Figo 7 is the coupling body 44 in the rest position of its parts ent corresponding to the coupling body 44.1 shown.

A coupling body 44 has a core 81 which is generally made of metal. The core 81 largely has the shape of an elongated circular cylinder. Of the Core 81 has a central part 82 and two coupling heads 83.

In the longitudinal center of the middle part 82 there is a radially aligned blind hole 84. On the middle part 82 is a handle part 85 pushed on, which has the shape of a circular ring Cylinder has. The inside diameter of the handle part 85 is at least approximately equal to the outer diameter of the central part 82. Its axial dimension is somewhat smaller than the middle part 82. This handle part 85 is made of plastic. Its outer peripheral surface is knurled equipped with an increased grip. The handle part 85 has a cross-sectional plane in its middle Through hole 86 for receiving an adjusting screw 87. The through hole 86 has two sections. The outside located section is on the inclusion of the screw head the adjusting screw 87 matched * The subsequent

Section of the through hole 86 is internally threaded

provided, into which the threaded shaft of the adjusting screw 87 is screwed will. The adjusting screw 87 is provided with a cylindrical extension 88 which is connected to the blind hole 84 in the Middle part 82 of the core 81 is matched, in which it engages when the set screw 87 in the through hole is screwed in.

The two coupling heads 83 each have a diametrically continuous one Recess 91, the two side walls 92 of which are flat and are aligned parallel to one another. They have a certain clear distance from each other. The recesses 91 are used to receive two hooks 93 each Width matched to the clear width of recess 91 so that the hooks are guided laterally in it.

The two hooks 93 of a pair of hooks are designed to be identical to one another. They have a hook nose 94 on a hook shank 95 ai f. The hook surface 96 is arranged on the side of the hook nose 94 facing the hook shank 95. The outer surface 97 of the hook lugs 94 is designed as a section of a circular cylinder surface which is at least approximately the same as the outer surface of the core 81 and which in the rest position of the hooks 93, which is shown on the right in FIG. 8, are aligned parallel to the outer surface of the core 81 so that they do not protrude beyond the axial projection surface of the coupling heads 83.

At a certain distance from the hook nose 94, on the rear side of the hook shaft 95 facing away from it, a recess 98 is arranged as a bearing surface, which recess has the shape of a hollow circular cylinder section. The central angle of this circular cylinder section is smaller than IBO ⁰ , namely by at least the pivoting angle of each hook 93, which results when the hooks 93 from the in

- IB -

f Fig. B rest position shown on the right in their operating

j position, which is shown in Fig. 8 on the left

; is. This pivot angle is indicated on the left in FIG. 6.

The rear side of the hook shaft 95 is aligned obliquely with respect to the front side by precisely this pivot angle (Fig. 14). The back of the hook shank 95 is a flat surface. The front side 99 is a circular cylinder section formed, which is matched to the inner surface of the insertion holes 57 and in the operating part of the hook 93 (in Fig. 8 x left) is aligned parallel to this circumferential surface.

For mounting the hooks 93 of a pair of hooks, there is a right angle on each coupling head 83 in the region of the recess 91 there is a circular through hole 101 aligned with the side winds 92 of the recess 91, into which a matching circular cylindrical bearing pin 102 is inserted. The hooks 93 are thereon with their recess or storage area 98 created. The bearing surface 98 and the bearing pin 102 together form the pivot bearing 100 of Hank 93.

To operate the pairs of hooks, that is, to pivot the hooks from their rest position (Fig. 8 right) into their Operating position (FIG. 8 left) there is an actuating device 105 for each pair of hooks.

An actuating arm 106 belongs to the actuating device 105 on each hook 93. It is designed in an extension of the hook shafts 95 protruding beyond the bearing surface 98. At the side facing away from the hook nose 94 at the end of the actuating arm 106 is a Nachführglied 107 in the form of a lateral extension of the actuating arm 106 forward "'hands. At the end of 107 is a ground Nachführgliedes

surface 108 arranged as a section of a circular cylinder surface is trained. Si & is in the operating position of the

-.19 -

two hooks (Fig. 6 and Fig. B left) aligned parallel to the outer surface of the core 81 and arranged so that in this operating position they do not over the axial Pröjek- i

tiönsflache of the core 81 protrudes. The contact surface 108 has the same curvature as the peripheral surface of the core 81.

As a further part of the actuating device 105 is a Actuation giied iti available. It has the shape of a on the outside Circular cylinder section, the outer diameter of which is at least approximately equal to the outer diameter of the handle part 85. This outer diameter is also at least approximately the same as the outer diameter of the outer contact surface 53 on the node bodies 43 uf i of the outer contact surface surfaces 77 on the framework bars 41. The actuating member is designed as a plastic part similar to the handle part 85, the circumferential surface of which is increased by knurling Has grip.

Part of the actuating member 111 is a rotary sleeve 112

educated. It has an axial through hole 113 which is matched to the core 81 of the coupling piece 44 so that a light running seat or a sliding seat is given. Of the The second part of the actuating member is a cam carrier 114 formed, which is made in one piece with the rotary sleeve 112. The through hole 113 of the rotary sleeve 112 goes into full width also through the cam carrier 114.

On the inside of the cam carrier 112, around the through hole 113, there is a cam surface 115 as an inner circumferential surface of the cam carrier 114 . This has on the one hand a smallest radial distance from the longitudinal axis 116 of the actuating member 111 , which is at least equal to the radius of the through hole 113, and on the other hand a largest radial distance which corresponds to the maximum actuation travel of the tracking member 107. This

. ä »« nt- -

The actuation path depends on the radial elevation of the hook nose 94 opposite the front side 99 of the hook shaft 95 and the ratio of the lever arms on the one hand to the hook nose and on the other hand of the actuating member 107, based on the bearing surface 89. This actuation travel is generally approx. 3.0 ... 3.5 mm. The cam surface 115 is arranged twice on the cam carrier 114 because both hooks 93 of a pair of hooks are to be actively actuated by them. The NccksnfIschs is accordingly formed point sync-h 2ϋΓ · longitudinal axis · For the sake of simplicity, this cam surface 115 is designed as the circumferential surface of a long, circular recess (Fig. 13). Since this cam surface, which is easy to manufacture, is axially symmetrical with respect to two axes crossing at right angles, a cam track for a point on the central plane of the tracking element extends over a central angle of 90 °. Because of the finite width of the tracking element 107, at the ends of the cam track, one half of it and the other half protrude beyond the theoretical end point of the cam track. Since the

ZO at least approximately the radius of curvature of the contact surface 108 is the same as the smallest radius of curvature of the cam surface 115, but this does not interfere with surviving.

So that the cam surfaces 115 and the tracking members 107 always have the correct axial assignment to one another are, the actuating members 111 are rotatably mounted on the core 81, but non-displaceable in the longitudinal direction guided. For this purpose, each rotary sleeve 112 enters radially aligned through hole 117 for receiving an adjusting screw 118. This is similar to the adjusting screw 87 formed on the handle part 85. The through hole 117 again has two sections, one of which The section with smooth surfaces receives the head of the set screw, while the other section has an internal thread is provided, in which the threaded shaft of the adjusting screw 118 is screwed, similar to that in the Handle part 85 and its adjusting screw 87 is the case. the

Adjusting screw 118 also has a thread-free end section here in the form of the cylindrical extension 119. This engages in a circumferential groove 121 on the core 81. Of the The diameter of the extension 119 and the width of the circumferential groove 121 are matched to one another in such a way that the actuating members 111 can be rotated, but not displaced permit.

The end face located on the side of the cam carrier 114 of the two actuating members 111 each forms an outer contact surface 120 for the coupling body 44. The outer diameter these contact surfaces 120 is at least approximately equal to the outer diameter of the outer contact surfaces 53 the node bodies 43 and the contact surfaces 77 on the truss rods 41. The inside diameter of the contact surfaces 120 is determined by the contour of the cam surface 115. There this one here has a long course is the smallest The inner diameter of the outer contact surfaces 120 at two points is still equal to the diameter of the core 81.

Since the actuating body 111 have a whole specific axial length, which is 30 mm, for example, and there also the handle part 85 located between them also has a certain axial length, for example 20 mm is, and since, in addition, the two actuating members 111 in the axial direction on both sides of the handle part 35 this results in an external distance between the two outer contact surfaces 120 of the coupling body 44 of, for example 80 mm. The distance between the end faces of the truss rods 41 and the node body 43 is then determined that they are coupled. Taking into account the dimensions of these parts given above, this leaves us the truss rods 41 within the conical surface, which are indicated by the dashed lines 57 in FIG are.

For each actuator 111 there are two rotation stops 122 and 123 are present, which limit the rotary travel of the actuators 115 on the one hand in that rotary position, in which the cam surface 115 in the relative position to the Tracking members 107 for the rest position of the hooks 93 is, and on the other hand, limit it in those rotational position in which the cam surface 115 in the relative position to the follow-up members 107 for the operation of the hook 93 stands. The two rotary stops 122 and 123 are on the one hand by the extension 119 of the adjusting screw 118 and, on the other hand, each formed by a dowel pin 124 or 125, which is inserted into a blind hole 126 or 127, respectively are mounted in the groove bottom of the circumferential grooves 121 are. The adjusting screws 118 accordingly act on the actuators 111 in the longitudinal direction and in the Circumferential direction as stop pins.

The angular position of the blind holes 126 and 127 is chosen so that in the rest position of the hook 93 (Fig. 6) the adjusting screw 87 of the handle part 85 and the adjusting screws 119 of the two actuators 111 are in the same diametrical plane and they are thus along a common cylinder surface line of the three cylinder bodies with one another cursing. This means readiness for joining or readiness for plugging in or, conversely, readiness for pulling out a coupling body 44 clearly indicated. When one or both of the actuators 111 from the rest position are rotated out into the operating position, whereby the hooks 93 pivoted into their operating position are, this is also clearly indicated by the fact that the relevant adjusting screw 119 of the actuator 111 with the adjusting screw 87 is no longer aligned with the handle part 85.

A common back-filling device is used for the hooks 93 of a pair of hooks 128 available, which the hook 93 from the operating position (Fig. 8 left) in their rest position (Fig. 8 right) returns as soon as the associated

- 23 -

Actuating member 111 from the rotary position for the operating position into the rotary position for the rest position of the Hook 93 is turned back. This return device 128 has a spring member 129 in the form of a helical tension spring. One end of each is attached to a suspension element 130 hung on each hook 93. These suspension elements 130 are in the form of a pin-shaped extension of the end face of the hook shaft 95 is formed. These pin-shaped suspension elements 130 are expediently with at least one on the outside of the corresponding hook provided a circumferential groove into which the suspension eyelet of the helical tension spring 129 is hung in order to prevent it from slipping off the pin-shaped hanging member 130. Instead of an extension made in one piece with the hook shaft 95, a pin-shaped body can also be used, which is inserted into a corresponding blind hole in the hook shaft 95 and therein, for example, by means of an upsetting process is secured. To secure it, such a pin can also be soldered or welded to the hook shaft 95 will.

16 is a modified core 131 for a Coupling body can be seen, the only one coupling head 133 in addition to the central part 132 in the construction described so far having. At the other end of the middle part 132, instead of a coupling head, there is a connecting element in The form of a threaded blind hole 34 is present. This means that other structural components, e.g. parts of a rope guy, can be screwed on by means of which pure tensile forces can be exerted on the node to which the coupling body is coupled. That comes first of all to creation of diagonal struts into consideration, t: «i which only tensile forces occur, for the transfer of which the normal truss rods 41 would be too bulky with regard to their weight or also with regard to the aesthetic effect. On one Coupling bodies with the modified core 131 can of course also be attached to expansion parts.

The clamp holders 45 have two half rings 136 and 137 which have an almost semicircular plan. Of the inner radius of the half-rings is at least approximately equal to the outer radius of the truss rods 141 or the Support pillars 142. The two half-rings 136 and 137 are at an adjacent end portion 138 and 139, respectively articulated to one another by means of a hinge clip 141. At the other end, they can be clamped against one another by means of a clamping device 142.

The half rings 136 and 137 are designed as sections of a circular ring cylinder which have a certain height. in the In the area of the end sections 138 and 139 there is an axially aligned through hole 143 and 144, respectively. The A- the other facing end faces of the half-rings 136 and 137 are Rounded in the shape of a circular cylinder, the cylinder axis of this rounding at least approximately with the perpendicular The longitudinal axis of the through holes 143 and 144 is aligned.

The hinge clip 141 has a U-shaped curved bracket 145, the two straight legs 146 and 147 of which are aligned parallel to each other and have a certain mutual distance. The web portion 148 of the bracket is at least approximately straight and each at right angles aligned with legs 146 and 147. At both Legs 146 and 147 each have a circumferential groove 149 on the end portion facing away from the web part 148, such as it is common for circlips · :. To the hinge clip 141 still includes a chain lock link 151, which is seen from the side is inserted into the circumferential grooves 149 and then therein snaps into place. Therefore, the axial clear distance between the circumferential grooves 149 and the inside of the web part 48 is at least equal to the axial height of the half rings 136 and 137.

The tensioner 142 has two pairs of tangentially aligned and aligned holes 152 and 153 on. Each of the two holes 152 is accommodated in a respective tab, which is attached to one at the end of the half-ring 136 whose end faces are present as an axial extension. In a corresponding manner, the holes 153 are each one Tab 155 attached to half-ring 137. The holes 154 are once removed and have smooth peripheral walls. she

take the head of one clamping screw 156 each. the

Holes 153 in the tabs 155 on the half-ring 137 are as

Threaded holes formed. The threaded shaft of the tensioning screws 154 is screwed into it.

In the middle plane of the half rings 136 and 137 are as Connecting elements for the coupling of other parts A number of radially aligned threaded holes 157 and 158 are available. Dia Geuindelholes 157 and 158 are on the circumference of the Half rings 136 u '\ d 137 are generally evenly spaced arranged, the arrangement pattern opposite the dividing joints of the two half-rings 136 and 137 by at least half a division is twisted. The clamp holder 45 shown has four threaded holes 157 and 158, so a total of eight threaded holes. Depending on the intended use and location of this clamp holder, the number of Threaded holes can also be smaller or larger. In addition, some or all of the threaded holes can be arranged irregularly, in particular as required on a case-by-case basis.

For the connection with a clamp holder 45 are suitable before all those coupling parts that have a collar bolt 161 or 162. On one side of the covenant 163 or 164 is a threaded bolt 165 and on the other side a smooth shaft 167 or 168 is present. This is closed a hook end 169 bent or with an eyelet 170 Mistake. This ring eyelet 170 can either be on the shaft 168 be welded on, or it is bent from a corresponding longitudinal section of the shaft 168 *

Truss rods can be used for vertically aligned parts of the truss as well as for horizontally and / or inclined parts of the framework. Since vertical truss parts are ideal for to attach not only parts of the technical expansion, but also exhibits in one way or another, it may be expedient to use one or more support columns 42 instead of half-timbered bars 41.

The Qi drschnittsform a support column 42 has an inside located ring part 171, the one at least approximately has a circular plan. Central to the ring part 171 are a plurality of ring sections 172 arranged evenly distributed, each having a radially aligned web part 173 with the Ring part 171 are connected. Between those facing each other Longitudinal edges of two adjacent ring sections 172 are each one running in the axial direction and one in the radial direction Direction of a continuous longitudinal gap 174 is present. The longitudinal gaps 174 have a certain width. The one at a longitudinal gap adjoining area of the inner wall 175 of the Ringahschnitte 172 is flat and oriented so that the inner walls 175 located on both sides of a Lätigsspaltes are at least approximately aligned with one another.

In the central radial plane of alignment of each longitudinal gap 174 there is a number of through holes ″! 76 on the ring part 171. They are circular. Their diameter is smaller than the width of the longitudinal gap 174. The through holes 176 are in the longitudinal direction of the support column 42 arranged distributed evenly (Fig. 25 and 26).

The support columns 42 are provided (in a manner not shown) on at least one end face with an end cap which has an insertion hole for the coupling of a coupling body 44, as in the case of the framework bars 41 on both

End faces is the case. The second face of the supporting pillars 42, with which it is placed on the floor, can be without such an end cap. To compensate for Unevenness in the floor on which a trade fair stand 40 is to be set up is used to support pillars 42, which to the effect are modified that in the lower end portion 177 of the ring member 171, an internal thread 178 is attached, namely is generally incised. For such support pillars 42 ' a foot IBl is available. This has a base plate 182 on, which is generally designed as a circular disk. In the middle of the footplate 102 a shaft 183 is arranged, either over its entire length or at least at an end portion facing away from the base plate 181 with a Screw thread 184 is provided, which is on the internal thread 178 in the support column 42 'is matched * With the help of this foot 182 height differences of the floor up to to be balanced to some extent.

The suspension supports 46, which can be suspended from the support columns 42, have an upper coupling part 185 and a lower coupling part 186, which are firmly connected to one another via a strut 187. With these A support arm 188 is connected to parts.

The upper coupling part 185 has an upper rod part 191 which is produced in one piece with the support arm 188 is. These two parts are formed by a metal rod with a circular cross-section. Your outside diameter is at least in the area of the upper rod part 191 is somewhat smaller than the width of a longitudinal gap 174 of the support columns 42. At the end of the upper rod part 191 facing away from the support arm 188, a double hook 192 is arranged. It is formed by a length of a metal rod with a circular cross-section. He's with the top one Rod part 191 inextricably linked, in general welded on, provided that both parts are made of a weldable metal such as steel or aluminum. Of the

-.28 -

Double hook 192 is at right angles both to the upper rod part 191 and the support arm 188 as well as to the strut 187 out ^ directs. The length of the double hook 192 is less than that clear distance between two adjacent web parts 173 of the support pillars 42.

The lower coupling part 186 is formed by a lower rod part 193 and a pin 194. The lower Stanyentcii 193 is aligned parallel to the upper rod part 191 and is preferably formed in one piece with the strut 187, with respect to which it is bent at right angles. At the free end of the lower rod part 193, the pin 194 is arranged in the center thereof. It is formed by an extension of the lower rod part 193, which is offset in diameter in the rod part 193. This diameter of the pin 194 is matched to the diameter of the through holes 176 on the ring part 171 of the support columns 42, so that it can be easily inserted into it ^ (Fig. 26). Between the pin 194 and the lower rod part 193 there is a flat, annular contact surface 195 with which the lower rod part 193 rests against the outside of the ring part 171 of a support column 42 when its pin 194 is inserted into one of the through holes 176 in the | Ring part 171 is inserted (Fig. 26).

The upper coupling part 185, the lower coupling part 186 and the strut 187 together form a holding device the hanging support 46 for hanging on a support column 188.

A suspension support 46 is hung in such a way that initially with the strut 187 aligned horizontally upper rod part 191 with the then parallel to the longitudinal gap 174 aligned double hook 192 is inserted first into the relevant longitudinal gap 174. After that, the Suspension support 46 rotated about the longitudinal axis of the upper rod part 191 so far that the strut 1B7 is the

parallel alignment to the longitudinal gap 174 approaches. At the same time, the suspension support 46 on the support arm 188 is raised so far that the pin 194 can move along the outside of the support column 42 until it is in the middle plane of alignment of the longitudinal gap 174. Then the support arm 188 is lowered again and the horizontal position is approached ^ whereby the pin 194 either first abuts the outside of the ring part 171, or, in the case of the Γ IC11 υ j. y B Π nüäriCiiuÜMy 5Ui uic r lüCiaii Γι icil uE5 5 ü 3 y 5 'η Η ι Ij. υ 6 Π through hole 176, immediately enters the relevant through hole 176 until the contact surface 195 rests on the outside of the ring part 171. A vertical force component that loads the support arm 188 is supported on the hole wall of one of the through holes 176 by the pin. The load moment resulting from the off-center application of the load is supported on the one hand by the double hook 192 on the upper rod part 191 on the inner walls 175 on both sides of the longitudinal gap 174 and, on the other hand, by the contact surface 195 on the lower rod part 193 on the outside of the ring part 171.

The apparent from Fig. 26 horizontal alignment of the support arm 188 is achieved in that between the Rod part 188 facing surface line of the double hook and the contact surface 195 at least approximately the same Distance is maintained, the inner walls 175 from the to they have parallel tangential plane of the ring part 171. If a different orientation of the support arm 188 is desired is, it can either be bent towards its holding device or it can be the distance between the Contact surface of the double hook 192 and the contact surface to be changed.

A particularly advantageous embodiment of the kit is shown in FIG. There are the truss bars 41 ' compared to the other Fachirerkstäben 41 modified by in the bottom part 196 of their end caps 197 one or more

Connection elements 189 attached for supply lines are. These connection elements 198 are single-pole or multi-pole Outlets trained. In addition, there are a number of coupling lines 199 at both ends are each provided with a plug 200 which are matched to the sockets 198. The type of coupling lines 199 and the type of sockets 198 as well as dje The type of connector 200 depends on the type of supply medium, that through sis from a truss .Turn should be forwarded to others.

The length of the connecting lines 199 is expedient once on the connection of a truss rod 41 ' matched to a second truss rod 41 'aligned at an acute angle up to a right angle to it and on the other hand to a connection of a truss rod to a truss rod 41 diametrically opposite it tuned out. The arrangement of the connecting lines 199 is then restricted entirely to the very immediate vicinity of a node. The supply lines are continued within the framework bars 41 ', u.ld either up to the opposite end of the relevant truss or up to a point of consumption in between or Branch point. The latter applies above all to truss rods 41 'which have a hollow body with an open profile. In the interior of such truss rods 41 ', for example, busbars of commercially available busbar systems are accommodated, at which then at any point along the length of a truss e.g.

Lighting fixtures can be connected by clipping them into the power rail with appropriate connection feet will. With this configuration of the kit, exposed supply lines are practically complete avoided.
