The invention relates to a connecting device in the preamble of claim 1 mentioned Art.

DE-OS 2 448 758 discloses a connecting device for connecting two load-bearing profile components have become known, e.g.

for connecting a post to a transom, the profile components have undercut grooves running in the longitudinal direction on their outside, in which two claws of a clutch can engage. Both the claws of the clutch as well as the undercut grooves have sloping contact surfaces, which cause the coupling claws in the grooves during the assembly of the coupling get drawn into it. After tightening a clamping screw serving as a fastening means the post is rigidly connected to the transom via the coupling.

The essence of this previously known construction is that the Coupling has two claws which can be moved towards one another and which are located behind the self-supporting Clamp the T-profile sections of two adjacent grooves when the clamping screw is tightened will. The disadvantage of this known construction is that the means The surface construction element flanged to the post of the coupling only in the right Angle can be attached to the post. The construction leaves no angular Adjustment of the surface construction element in relation to the post to, as well how no continuous change of a once set angle is possible is. In addition, with the relatively wide coupling element on each one Side of the post only a latch can be attached, so that the known construction Variations in the creation of stand units are only permitted to a limited extent and therefore in itself is not suitable for exhibition stand construction. As the coupling element each overlaps a plurality of undercut grooves on one side of the post, is causes a considerable loss of space, so that only a few surface construction elements can be attached to a profile body or post.

DE-OS 2 535 388 is a connecting device for with variable angles in one another fixable surface construction elements with to the Butt edges of the surface construction elements each definable profile rails, each having an open profile piece with an arcuate cross-section and are hereby brought into mutual engagement, become known, with several Profile rails plugged into one another in this way can be fixed by bolts that can be inserted at the front are. In this known arrangement, the arcuate profile pieces have the shape a spiral. However, since the spiral has one over its entire arc length continuously changing radius, the interlocking ones lie around A certain angle q against each other offset arc pieces due to each different Curvatures in the same place do not fit neatly together, but rather gape apart. This causes a considerable loss of space, so that only a few arc pieces can be nested. Since a mutual clean system only then can be achieved if the interlocking elbow pieces are bent accordingly, pressure pieces are required, the corresponding radial forces on the bend pieces exercise. This creates the risk that the radial explosive forces that occur cannot be absorbed by the arc pieces to be fixed to one another. This therefore requires relatively large arc lengths, so that only a few profile pieces are connectable to each other. On the other hand, there is also the risk that the radial explosive forces break the form fit, so that the rails fall apart.

Another disadvantage is that when the pressure hulls are tightened a subsequent angle change or angle adjustment of the surface construction elements is no longer possible, whereby the assembly effort can be increased. If nevertheless, if a torque is accidentally applied, it can be as a result of the Pressure hulls prevented rotational movement leading to a pincer-like tilting movement of the nested Elbow pieces come, whereby the form fit can be broken and the connection as a result, falls apart. It can also be assumed that the above Existing rubber pressure body only a locally limited, mutual system effect and the rails thus only the desired in the area of their ends have mutual contact, which is especially true for rails with relative long length can have a detrimental effect on the stability and security against shaking. The known arrangement therefore requires a not inconsiderable assembly and Control effort if assembly errors are to be excluded. In this regard It must also be taken into account that arrangements of the generic type are particularly important in Trade fair and exhibition construction are used and thus usually non-specialist People are exposed.

Finally, there is another disadvantage of the known construction in that there are fewer profile rails in certain angular positions when they are put together result in open joints that have to be covered by appropriate cover pieces, so as not to adversely affect the optics. After all, the familiar demands Construction involves the use of many individual parts, such as bolts, fasteners and frames to put up a wall. Any breakthrough in a wall around showcases or Door inserts or other objects to be attached require additional, new elements, which did not fit into this system.

The invention is therefore based on the problem of avoiding the Disadvantages of the known solutions a connecting device of the generic type Kind to improve so that a quick and easy to assemble, hinge-like Connection can be created, which allows a variable setting of the interconnected Surface construction elements to each other as well as one after the setting made feasible fixation of the surface construction elements allows, at the same time the number of components used is reduced and the manufacture thereof is simplified and the variability in the creation of stand units is to be increased.

This object is achieved according to the invention in that the profile longitudinal grooves of the profile body in the area of the undercuts on the flank side of circular arcs are limited, and that the respective engagement profile a in cross section to a Has undercut adapted, curved profile piece, which is inserted in the State can be fixed by means of a locking device relative to the profile body is.

Due to the design of the connecting device according to the invention the disadvantages existing in the known constructions become more advantageous Way eliminated. The measures according to the invention result in a hinge-like connection, with a subsequent change in the angle of the interlocking profile parts the surface construction elements attached to it is easily possible. By the connecting device according to the invention becomes the system for creating more variable Stand units essentially on two profiles as well as the one used for fixation Closure device reduced. The connecting device according to the invention enables the connection of finished panel elements by laterally nesting and Locking the curved profile pieces in the profile longitudinal grooves of the profile body, whereby a flawless, statically resilient connection is created, without larger ones Having to compromise. It will now without the use many individual parts with just two extruded profiles, including hinges for whole Doors, etc. to be made flawlessly. Corner profiles are omitted, and when using a post profile in the form of a closed tube profile becomes statically high Resilient construction achieved without limiting the variability. The post profile can be connected to the surface construction elements in such a way that that it is set up in the middle or with an off-center offset.

A single post profile enables multiple walls to be attached in continuously adjustable angles, so that showcases or chests can be steplessly up to a polygon can be assembled. There are also no profile millings and / or cuts are required, so that the manufacturing costs are significantly reduced will.

The connecting device according to the invention enables the creation of double walls, between which a groove remains free, in which specialist supports, Drawers or other anchors can be attached. The one between Two double walls resulting cavity can be used for the passage of lines or for Taking advantage of showpieces.

The fixation of the profile pieces engaging in a profile body takes place via the versatile closure device according to the invention, which Profile piece retracted into the profile longitudinal groove in any angular position stuck against the profile body. The two extruded profiles are almost uncompromising Can be further connected with screws, i.e. a post profile for a flat ceiling or sliding ceiling by means of a simple angle screw connection to be assembled. The post profile is simply cut off and by means of a Screw can be rotated again and thus serves as a stable door linkage, if necessary also a double door linkage, without additional standing in the area Needing profiles. the The door can easily be double-walled run and has the advantage that you cannot go through the door gap without a door seal can see through. Conventional locks are also included in this so-called double door in the simplest way without millings etc.

to be attached, the closing body engaging in a longitudinal profile groove can. First of all, there is a trade fair stand using the connecting device according to the invention has been created, then it is easily possible despite the static load the ceiling and other fixtures, subsequent specialist editions or other attachments to be attached regardless of the type. The connecting device enables the execution various ceiling systems in which the ceiling is either placed on top or between is mounted on the upright profiles. The connecting device according to the invention facilitates in addition, the creation of walls. The edging of the stand construction elements Walls used previously had to be carried out with frames in order to achieve the necessary stability to achieve. When using the connecting device according to the invention are such frames in the horizontal direction are not necessary.

The walls created using the post profiles are flawless Can be connected by pulling and pushing by means of screws simply attached to the end. Through bolts, as they were previously necessary and also a bad compromise are completely omitted.

In the double-walled construction, the connecting device according to the invention enables a mutual locking function of the surface construction elements and facilitates thus putting up a long straight wall. But with this locking function worked, every second post profile must be inserted at the front. In the Execution of showcases is done by inserting a plastic tape into the existing ones Frames without that Tape must be visible. The sliding glass doors As is usual with glass showcases, you can simply go through without additional elements the double wall system can be achieved. Grooving the surface construction elements to achieve closed stand construction elements can be done using a simple hand plane can be achieved.

The longitudinal profile grooves even enable drawer guides horizontal use of the profile body if the locking device without pressure body is used. The hanging of the elements connected to the surface construction Profile pieces in the upright profile is itself a horizontal arrangement for one Cover very easy because the profile piece as well as the locking device despite the pivoting movement when inserting when tilting by hanging no torque generated, i.e.

that by leaving such a surface construction element hanging an opposite pivoting moment is generated between above and below, which As a result, the surface construction element simply stops when it is released.

The new connecting device is therefore due to the simplicity of its Elements, high stability, easy assembly and very large application possibilities characterized, the device for connecting stand components without Frames, stand construction elements with frame edging for the purpose of further connections and can be used to form double-walled designs, especially with large Exhibition stands have the advantage of making cables disappear in the double wall or to incorporate a one-sided shop window into the system.

Further advantageous refinements and developments result based on the following description of preferred exemplary embodiments the drawing in conjunction with the subclaims. Show in it: Fig. 1 shows a schematic horizontal section through a post profile with two longitudinal grooves in the profile engaging engagement profiles; Fig. 2 is a horizontal sectional view through a Part of the post profile with an inserted engagement profile, which by a Locking device is fixed; 3 shows a schematic side view of a post profile with inserted engagement profiles, the left engagement profile by a locking device is fixed on a different scale; 4 shows a further preferred embodiment for the connecting device, consisting of an engagement profile and a profile body similar to the engagement profile; Fig. 5 is a schematic sectional view by a central frame, which is used for long walls, and FIG. 6 shows a schematic sectional view through a ceiling frame.

Fig. 1 shows a first preferred embodiment for the Connection device 1 according to the invention, which essentially consists of only two extruded Profiles, namely in this embodiment from the upright profile 2 and engagement profiles 3, 4 is formed.

The upright profile 2 is an aluminum hollow profile and has in his Edge area of longitudinal profile grooves 5 which have undercuts 6, 7. Any undercut 6.7 is in its flank area by two arcs with the radii R1 and R2 limited. Silk radii have a common center point M.

This center point falls in the exemplary embodiment shown with the geometric center of the cantilevered section 8 between two adjacent ones Profile longitudinal grooves remaining T-flange 9 together. The bottom of the profile longitudinal groove 5 is therefore limited by two arcs R1, which are on the symmetry Cut S for the undercuts 6, 7.

The groove width, which is drawn in in the upper right part of FIG is, results from the difference of the radii R1 minus R2, so that the arc-shaped Profile pieces 10, 11 of the engagement profiles 3, 4, the cross-sections of which are adapted to the respective Cross-sections of the undercuts 6, 7 are adapted, laterally in the post profile 2 can be introduced. This makes assembly easier.

However, it would also be conceivable that the cantilevered sections 8 of the T-flanges 9 are somewhat elongated at their outer edge, so that the once The engagement profiles 3, 4 introduced into the upright profile at the end are no longer sideways can be pulled out of the profile longitudinal grooves 5, since the cross-section of the profile pieces 10, 11 would have a greater width than the then existing groove width.

Due to the arched design of the flanks of the undercuts 6, 7, and a corresponding arcuate design of the profile pieces 10, 11 of the Engagement profiles 3, 4 to which the surface construction elements 12 are attached, There is the possibility that these surface construction elements compared to the Upright profile can be pivoted in a certain angular range without thereby the profile pieces come out of engagement with the associated intercuts. The limit positions result from the fact that the profile pieces against the face of the in each case in Ilintcrsclinci dung and with i also llalsbereich against a load bearing Section 8 of a T-flange 9 come to rest.

Such a limit position is, for example, determined by the two intervention profiles 3, 4 taken according to FIG. 1, and it can be clearly seen that the surface construction elements 12 then assume a parallel position.

With the connecting device 1 it is possible in this way e.g.

create a double door or a closed shop window, whereby in the case of the double door, the hinge is formed by the profile pieces 10, 11, which engages in the corresponding longitudinal profile grooves 5.

The profile longitudinal grooves enable the locking bolt or the bolt pin of a conventional door lock, so that with the invention connecting device lockable doors can be produced. Another application the connecting device according to the invention could be used to create a drawer find, in which the in the profile longitudinal grooves of a e.g. horizontally arranged Profile body 2 sliding profile pieces 10, 11 serve as guide parts of the drawer could.

The space 13 between two adjacent surface construction elements can also be used to accommodate cables and the like. Use while the middle hollow chamber 14 of the post profile 2 for receiving a leveling screw or the like

can serve.

In contrast to the exemplary embodiment according to FIG. 1, the engagement profile engages 4 according to FIG. 4 not in a post profile, but in a profile body 15 which e.g. also be attached to the face of a surface construction element can.

This type of connection device can be used, for example, during manufacture of walls or ceilings are used, the sections arranged at an angle to one another own. In Fig. 4 two positions of the profile body 15 are shown, whereby the swivel range is made clear.

In the schematic horizontal section shown in FIG a post profile 2, in the profile longitudinal groove 5 a profile piece (not shown) engages, the angular position of the surface construction element 12 is opposite fixed to the upright profile 2 by a locking device 16. This locking device 16 consists essentially of three parts, which are connected to one another by a threaded bolt 17 be braced.

The closure device 16 consists of a pressure body 18 and a split engagement profile piece 19, 20, the portion 20 also as a pressure plate should be designated.

From Fig. 2 it can be seen that the engagement profile piece 19, 20 likewise a section 21 adapted to the cross section of an undercut which corresponds to the profile pieces 10, 11. So this section can as well as the profile pieces 10, 11 are introduced into the profile longitudinal groove 5 and perform the same angular movement together with the engagement profiles 3, 4.

The pressure body 18 has a spherical sliding surface 22, which a corresponding sliding surface 23 of the pressure plate 20 is assigned. The pressure hull 18 also has a passage opening 24 for the section 21, dle in i tlrer I 'riti i <is rartly developed, <let it eirlc angular movement of the vessel construction 12 with the locking device 16 attached thereto. The Fig. 2 also leaves recognize that the pressure body 18 engages in part in the profile longitudinal groove 5 and is adapted at its tlntcrscite to the curvature of the post profile 2, so that the Pressure body serves as an additional guide for section 21.

To fix the surface construction element 12 in any Angular position with respect to the upright profile 2 now only needs the To be tightened threaded bolt 17, so that the pressure plate 20 with its spherical Sliding surface 23 is drawn against the spherical sliding surface 22 of the pressure body 18 and thus tensioning takes place.

The closure device 16 has a recess 26 in which the head of a threaded bolt 27 can be received to the locking device 16 to be connected to the surface construction element 12 on the end face.

The side view according to FIG. 3 shows the advantageous one particularly clearly emerge visual impression of the connecting device according to the invention. It it can be seen that between the upright profile 2 and the engagement profile 4 no open joint remains, so that the space between two surface construction elements, for example 12 is completely closed and thus as a window or to accommodate cables suitable is. From Fig. 3 it can also be seen that the hollow chamber 14 of the Upright profile 2 may have an internal thread 29, which is used to connect a further Upright profile or to accommodate a leveling screw or the like. Can serve.

Fig. 5 shows a central frame 30, which can be used, for example, as an enclosure frame for Surface construction elements 12 can serve, so that larger with the help of this frame Walls can be created.

The double frame 31 shown in FIG. 6 can be used in conjunction with find the connection device according to the invention as a ceiling frame use.
