Description

The invention relates to a connecting device for connecting, preferably similar, profile elements, in particular a frame, pedestal, stage and / or grandstand construction, with a profile element, a sliding block for engaging in a groove between the profile elements to be joined and a gag for connecting the profile elements, wherein the knob has a handle portion and a pin member, wherein the pin member of the knob passes through the profile element and being held in an initial position of the knob on the handle portion remote from the side of the profile element in the extension direction positively on the sliding block. Furthermore, the invention relates to a connection between, preferably similar, profile elements, in particular a frame, pedestal, stage and / or grandstand construction, comprising a corresponding connection means.

To provide various constructions, profile elements must be interconnected. The profile elements may in particular be elongated profile elements which have an at least substantially constant cross section. In many cases, as modular a construction of the construction is also desirable, which is why the profile elements to be joined together can be designed to be similar. Like means in this context that the cross sections of the profile elements are at least similar or substantially identical to each other. This is often the case in the production of frame, pedestal, stage and / or grandstand constructions, as they often occur for example in theaters, the case.

Such and proven in practice connection is in the DE 94 077 18 described. The invention serves to fix two elongated profile elements against each other. The profile elements can each be part of different frame structures. The profile elements have two box-shaped hollow profile sections, which are interconnected by a web portion. The web portion is offset from the sides of the box-shaped hollow profiles inwards and arranged there approximately centrally. Thus, the two profile elements to be connected each form outwardly open grooves. In these grooves, a correspondingly formed sliding block can be used, which has a central threaded bore. The profile elements have in the opposite web portions openings, can be inserted through the knob from the outside and screwed into the central thread of the sliding block. In this way, a positive and non-positive connection between the two elongated profile elements is obtained.

A disadvantage of the known compound that for the provision of the compound a number of items must be stored. This can lead to the fitter accidentally carrying an insufficient number of sliding blocks and gags. However, the subsequent procurement of additional sliding blocks and / or gag is associated with a high time and thus cost.

In addition, sliding blocks and toggles can be easily lost during assembly or disassembly of frame structures, which also leads to increased costs.

The present invention is therefore based on the object, the above-mentioned and previously described in more detail connecting devices or compounds such and further develop that their handling is simplified.

This object is achieved with a connecting device according to the preamble of claim 1, characterized in that the pin element has a connection means for connection to a further profile element.

The connecting device thus comprises at least one profile element, a sliding block and a gag. The profile element is preferably elongated and formed with a substantially constant cross-section. The connecting device serves to connect the corresponding profile element with a further profile element, which may be formed in particular similar. The required for the connection of the profile elements sliding block and also required gag are pre-assembled on a profile element. For this purpose, the pin element of the knob is inserted through an opening of the profile element. In an initial position of the connecting device, in which the two profile elements are not yet connected to each other, the toggle is held in a form-fitting manner on the sliding block. Thus, both the toggle and the sliding block is captively connected to the one profile element of the connection to be produced. The positive connection is achieved by the gag, in particular the pin member of the knob, on the side remote from the handle portion of the profile element engages behind a portion of the sliding block. Preferably, the handle portion of the knob is provided on the side facing away from the sliding block of the profile element so that the handle portion can not slide through the accessed by the pin element opening in the profile element therethrough.

However, the pin element of the knob is not only designed to produce a positive connection with the sliding block in the starting position. The pin element is also provided with a connecting means with which the knob can be connected to the other profile element to produce a connection between at least two profile elements. As a result, ultimately two things can be achieved. On the one hand, a pre-assembly of gag and sliding block on a profile element is possible, so that the gag and the sliding block can always be used for connection with another profile element. In addition, pre-assembled sliding blocks and toggles can not be lost accidentally. On the other hand, it is achieved in particular by the connection means of the pin element that, without additional individual parts starting from the starting position of the connecting device, a connection with the further profile element can be established. Since the corresponding connecting means is provided on the pin element of the pre-mounted on the profile element knob, if necessary, can be dispensed with further connecting elements. The pin element, in particular the connecting means, thus ultimately serves together with the sliding block both the pre-assembly of sliding block and toggle and the provision of the actual connection between the two profile elements.

In a first preferred embodiment of the connecting device, the connecting means can be arranged and / or received in the starting position in the sliding block. The connecting means is thus not facing the sliding block outwards and so can not obstruct or interfere with the approach of the further profile element to the connecting device, in particular the sliding block. This is particularly advantageous if the sliding block to engage in the formation of a positive connection both in a groove of a profile element and in a groove of the other profile element.

For a simple connection of at least two profile elements, it offers itself alternatively or additionally, if the toggle can be pushed further out of the starting position against the extension direction of the toggle. The gag, in particular the pin element, can thus be pushed further than in the starting position through the opening of the profile element. The displaceability of the toggle ensures that the connecting means can protrude on the side of the sliding block facing away from the grip portion of the toggle. The correspondingly protruding connecting means can then be used without interference from the sliding block for connection to a further profile element. The connection of the profile elements can preferably be made such that initially the two profile elements are approximated to each other. Subsequently, the knob can be moved in the direction of the further profile element, so that the connecting means protrudes relative to the sliding block in the direction of the further profile element and can be connected there to the further profile element. In other words, it is possible to allow the connecting means to protrude outward with respect to the sliding block in the direction of the further profile element only if this protrusion is actually required for connecting the further profile element via the connecting means.

According to a particularly simple structural design of the connecting device, the sliding block and the pin element each have a thread. If necessary, the threads may be formed corresponding to each other so that they engage with each other. But it can also be provided that the thread of the pin member engages behind the thread of the sliding block on the side remote from the handle portion of the thread of the sliding block. Then, the thread of the pin element in the extension direction can be held positively on the thread of the sliding block. It then follows that the gag is held in total positive fit on the thread of the pin member on the thread of the sliding block.

Such a configuration, in particular of the pin element, is particularly suitable when the connecting means is designed to form a screw connection. For this purpose, the connecting means may be formed, for example in the form of a thread which on the one hand represents the connecting means for forming a connection with the further profile element and on the other hand allows a positive connection with the sliding block in the starting position. As a result, a structurally simple and cost-effective connection device can be provided. Alternatively or additionally, however, the connection means can also be designed to form a bayonet closure or a camlock closure. For example, for this purpose, the connecting means may comprise at least one lateral projection and / or at least one lateral groove, which can form a positive connection in the extension direction of the toggle with a corresponding object. In particular, in the case of a lateral projection, such as in the form of a pin or bolt, this projection can be used simultaneously to provide in the initial position with the sliding block a positive connection in the extension direction of the toggle.

So that the installer can operate the connecting device intuitively and as usual or accidentally release the toggle from the Sliding block is prevented, the sliding block and the pin element of the knob can each have corresponding threads. In this case, the threads correspond in particular when the one thread can be screwed into the other thread. In order to simultaneously provide a structurally simple embodiment of the connecting device, the described thread of the pin member may be simultaneously the connecting portion of the pin member. By the two corresponding thread, for example, the circumstance can be taken into account that the installer is accustomed to mount the knob by screwing. In addition, it could be ensured by the appropriate choice of the thread that the gag can not be solved by a slight twist of the sliding block.

In order to simplify the connection of the connecting means to the further profile element and in particular to align the toggle for this operation beforehand in a suitable manner, a spring means can be provided between the grip portion of the toggle and the first profile element. Preferably, the spring means exerts in the initial position of the connecting device a restoring force, in particular in the extension direction, on the gag, which aligns this in the desired manner. In this case, a simple handling of the connecting device can be achieved in that the pin element is aligned parallel to the extension direction of the knob due to the restoring force of the spring means.

In order to be able to provide, for example, a simultaneously positive and non-positive connection between at least two profile elements, it is expedient if the at least one profile element has two hollow profiles and a web provided therebetween. The hollow profiles may preferably be box-like, d. H. with a square or rectangular cross section, be formed. The web is alternatively or additionally a rod-shaped cross-section element, which can be connected either directly or indirectly via other components with the two outer hollow sections. It is further preferred if the cross section of the profile element is formed substantially mirror-symmetrical. This can be achieved, for example, in that the web is arranged centrally in the extension direction with respect to the two outer hollow profiles. In this way, a groove can be formed between the hollow profiles and the web on at least one side of the web, in which the sliding block can at least partially engage.

In order to facilitate the connection of the one profile element to the further profile element and / or to be able to form-fit, it is preferred if the sliding block protrudes relative to the profile element. The sliding block can therefore have an extension transversely to the profile element, which extends beyond the depth of the groove in the profile element.

In order to increase the flexibility for the handling of the connecting device and to be able to ensure a substantially modular construction of a frame construction, openings can be provided in the profile element at regular intervals. Through the openings pin elements of gags can be passed, such as pre-assemble connecting devices on the profile element. With regard to the further profile element, openings may alternatively or additionally also be provided at regular intervals. These openings can serve, for example, connections with connecting means of the toggle.

The above object is also achieved in a compound according to the preamble of claim 11, characterized in that the pin member has a connection means and that in the connected state of the profile elements, the profile elements are connected to each other via the connecting means.

In this way, the advantages already mentioned in connection with the connecting device can be achieved. In this case, the connection may preferably comprise connection means of the aforementioned type. Their possible features have already been set out above, so that they are made in the present case by references to the subject of the aforementioned compound.

In a first preferred embodiment of the connection it is provided that the profile elements are non-positively and positively connected with each other. In this way, the requirements for frame, pedestal, stage and / or grandstand designs can be met structurally simple.

Alternatively or additionally, the sliding block may be provided in a gap formed by the connected profiles. In this way, structurally simple a positive connection of the two profile elements can be achieved. At the same time, the sliding block can be accommodated in this way but also space-saving in the connection of the two profile elements. This is especially the case when the two interconnected profile elements touch each other laterally. Alternatively or additionally, it can be provided that the gap formed by the two profile elements is formed by in each case an outwardly open groove of the two profile elements. In this case, the transverse extent of the sliding block to the width of the gap or the depths of the two forming the gap Be adapted to grooves. The sliding block can be adjusted in terms of its dimensions to the width of the groove, such as the distance between the hollow profiles.

In order to be able to achieve a connection between the toggle, in particular the connecting means, and the further profile element in a structurally simple manner, the further profile element can have a thread for receiving the connecting means of the toggle. The thread may, if necessary, be formed integrally with the profile element. This can be achieved, for example, by cutting the thread directly into the profile element. Alternatively or additionally, however, the thread can also be provided by a threaded element, which is connected by a suitable connection with the further profile element. It is particularly appropriate if the threaded element is held captive on another profile element. The connection of the further profile element with one or more threaded elements can preferably take place by way of pre-assembly at predetermined sections of the further profile element.

In order to provide a space-saving connection between at least two profile elements and to improve the power transmission from one profile element to the other profile element, the two interconnected profile elements in the connected state, preferably with their sides, abut each other. In this way, the closed connection can be further stabilized, since forces can be transmitted not only on the sliding block but also partially directly from profile element to profile element.

The invention is explained in more detail below with reference to a drawing showing only one embodiment. In the drawing shows

1 a frame construction with connections according to invention in a schematic plan view,

2 a connection 1 in a cross section along the section plane II-II 1 .

3 the connection off 2 in a longitudinal section along the section plane III-III 2

4 a connecting device according to the invention for forming the compound gem. 1 to 3 in a cross section gem. 2 ,

In the 1 is a frame construction 1 in the form of a pedestal construction made of profile elements 2 . 2 ' shown in a plan view. The profile elements 2 . 2 ' are in the illustrated and so far preferred frame structure 1 formed in the form of frames. The frame construction 1 is also made up of several frames 3 Together, the side over connecting devices 4 connected to each other. This in turn creates a frame structure.

In the illustrated and insofar preferred frame construction 1 are those using the connecting devices 4 formed compounds 5 shown schematically. In addition, in some corners of the frame 3 the frame construction 1 Recordings 6 provided in which legs 7 are held, with which the frame construction 1 gets up on a substrate.

The interconnected profile elements 2 . 2 ' are elongated and laterally using appropriate connecting means 4 connected with each other. About the connecting devices 4 Both positive and non-positive connections 5 provided. In the illustrated and insofar preferred frame construction 1 are the connecting devices 4 in each case only one of the two interconnected profile elements 2 intended. The connecting devices 4 but could alternatively also on both profile elements 2 . 2 ' , For example, be provided alternately.

In the 2 is a cross section through a corresponding connection 5 shown. The two interconnected profile elements 2 . 2 ' are similar to each other. Each of the two profile elements 2 . 2 ' is part of an adjoining frame 3 , The two profile elements 2 . 2 ' each have outer box-shaped hollow profiles 8th with a rectangular cross section. The two box-like hollow profiles 8th of each profile element 2 . 2 ' are centered on the box-like hollow sections 8th arranged bridge 9 connected with each other. The jetty 9 is in particular centrally between the two outer sides 10 the box-like hollow profiles 8th arranged. The box-like hollow profiles 8th form together with the footbridge 9 on both sides of the profile elements 2 . 2 ' similarly formed grooves 11 , The jetty 9 is present also parallel to the outer sides 10 of the profile element 2 . 2 ' aligned.

Approximately in the middle between the box-like hollow sections 8th is in the jetty 9 an opening 12 provided by a gag 13 with a pin element 14 can reach through. The opening 12 is not big enough for your passage of a handle section 15 of the gag 13 , The grip section 15 of the gag 13 is thus the side of the bridge 9 a first profile element 2 arranged. The pin element 14 of the gag 13 reaches through the openings 12 the two interconnected profile elements 2 . 2 ' , The profile elements 2 . 2 ' lie in the illustrated connected state on the sides facing each other 10 the profile elements 2 . 2 ' to each other. The mutually facing and outwardly open grooves 11 between the box-shaped hollow profiles 8th and the jetties 9 the respective profile elements 2 . 2 ' then form a common gap 16 or cavity within the connection 5 , In this form-fitting is a sliding block 17 added.

In the illustrated and so far preferred compound 5 shows the sliding block 17 a central hole 18 on, through which the pin element 14 of the gag 13 can be passed through. Sectionwise, on the handle section 15 of the gag 13 facing side of the sliding block 17 is a thread 19 provided with a at the front end of the pin element 14 provided connecting means 20 in the form of a thread corresponds. The connecting means 20 can therefore into the thread 19 of the sliding block 17 be screwed. With sufficient number of turns reach the threads 19 of the bonding agent 20 and the Kulissenstein 17 but again out of engagement. The thread of the lanyard 20 is then through the thread 19 of the sliding block 17 screwed through. The two threads 19 then form a positive connection in the extension direction of the gag 13 so that the gag 13 or the connecting means 20 not in the opposite direction from the Kulissenstein 17 can be pulled out.

In the illustrated and so far preferred connecting device is the thread 19 of the sliding block 17 provided in a metallic sleeve. This sleeve is captive in the base body of the sliding block formed of plastic 17 added. For transmitting high forces is also the pin element 14 of the gag 13 and at the front end of the pin element 14 provided connecting means 20 made of a metallic material. The grip section 15 of the gag 13 For the sake of simplicity, it is also essentially made of a plastic.

The pin element 14 can starting from the previously described and in the 4 illustrated starting position further against the extension direction of the gag 13 in the first profile element 2 be inserted. So can be achieved that at the front end of the pin element 14 of the gag 13 provided connecting means 20 , for example, completely, on the handle portion 15 opposite side of the sliding block 17 opposite the Kulissenstein 17 protrudes. The opposite the Kulissenstein 17 above connecting means 20 can thus with the second profile element 2 ' get connected.

In the illustrated and so far preferred compound 5 grips the connecting means 20 in the form of a thread in a corresponding thread 21 one on the other profile element 2 ' attached threaded element 22 , The further the connecting means 20 in the threaded element 22 further profile element 2 ' is screwed, the more becomes a between the first profile element 2 and the handle portion 15 of the gag 13 provided spring means 23 compressed in the form of a coil spring. With the compression of the spring means 23 increases the restoring force of the spring means 23 so that using the connection device 4 a both non-positive and positive connection 5 between the two interconnected profile elements 2 . 2 ' can be achieved. In the illustrated and so far preferred connection of the gag 13 be screwed up to an end stop, making it for the frictional connection 5 the profile elements 2 . 2 ' not on the presence of the spring means 23 arrives. The spring means 23 So mainly serves the pre-assembly of the connection device 4 and the orientation of the gag 13 in the starting position of the connecting device 4 ,

How, for example, from the 3 results is in the illustrated and so far preferred compound 5 the threaded element 22 captive, in this case via a screw connection 24 , on the further profile element 2 ' established. This leaves the threaded element 22 even after solving the illustrated and so far preferred compound 5 continue firmly with the other profile element 2 ' connected. But it could also be provided that both profile elements 2 . 2 ' both connecting devices 4 as well as threaded elements 22 wear. The connecting devices 4 and threaded elements 22 could then, for example, alternately or otherwise regularly distributed along the profile elements 2 . 2 ' be provided. Thus, for example, a possible modular construction of the frame construction 1 be created.

The illustrated connection is solved 5 simply in that the handle section 15 of the gag 13 until the thread is turned in a suitable direction 21 of the threaded element 22 and the thread of the connecting means 20 disengage. Now the two profile elements 2 . 2 ' be separated from each other. In addition, the restoring force of the spring means 23 between the first profile element 2 and the handle portion 15 of the gag 13 for that the thread of the lanyard 20 at the handle section 15 opposite side of the thread 19 of the sliding block 17 is present and remains there form-fitting in the extension direction. In this position, referred to as the starting position, the connecting means 20 at the front end of the pin element 14 of the gag 13 completely in the sliding block 17 recorded, in a recording section 25 between the thread 19 of the sliding block 17 and the handle section 15 opposite side of the sliding block 17 , This results in particular from the illustration according to 4 ,

In the illustrated and so far preferred connection device 4 is between the first profile element 2 and the spring means a washer 26 intended. The compressed spring means 23 is therefore supported in the direction of the first profile element 2 at the washer 26 from. In addition, form the washer 26 and the handle section 15 of the gag 13 a common end stop when the gag 13 completely screwed in. There are then the handle section 15 and the washer 26 to each other. But it could also rest other components to form an end stop together. In addition, could basically on the washer 26 be waived if the spring means 23 in a satisfactory manner on the first profile element 2 supported.
