State of the art

For industrial installations with heavy loads, eg. As for large pipes, steel structures are created. The individual components of the steel structure are usually welded together. Welds may only be made by specialized craftsmen and are expensive to manufacture. Subsequent adjustments and modifications of the construction are only conditionally possible. In explosive areas no welds may be made without a complex approval procedure and additional provisional structural measures.

There are known mounting systems for medium and heavy loads, comprising the system carrier, the system carrier having on the outer walls openings at a predetermined distance. At these openings, a plurality of connecting elements for connecting the individual components together along the system carrier in a, the spacing of the openings corresponding grid can be arranged.

A disadvantage of the known solution is that the known system carrier and the corresponding connecting parts have a high weight and the assembly requires a high manpower. Furthermore, one is bound to the given grid (eg 50 mm) with the known mounting systems. Fine adjustments are not possible with these systems. To ensure the flexibility of the known systems, these comprise a multiplicity of different connecting elements designed for special conditions.

From the DE 44 12 505 C1 is a device for fixing facade elements with a first and a second angle profile piece, which are composed to form a profile element with a substantially U-shaped or Z-shaped cross-section known. The juxtaposed legs of the two angle sections are provided with slots and with grooves, and on the juxtaposed legs of the angle section pieces are provided with grooves adjustment plates. The FR 2 552 174 A1 teaches an L-shaped holder for facade elements, which is also grooved.

Presentation of the invention

The object of the invention is to provide a connecting element for a mounting system, which ensures a simple and flexible installation of the carrier to be connected to the mounting system, as well as subsequent changes and additions to the created construction allows.

The object is solved by the features of claim 1. An inventive connecting element is characterized in that the connecting element has at least one bead, and that the toothing is arranged in at least one of the bead walls of the at least one bead

The latching means and the latching means engaged with counter-locking means provide a positive connection, so that a high level of security against failure of the compound created with the inventive connection element is given. The engaging in the locking means counter-locking means of the fastener prevents accidental slipping of the positioned connecting element. With the at least one elongated hole, the connecting element can be advanced over its length along the carrier, wherein the positioning and fastening of the connecting element from the grid the openings of the carrier is largely detached. The distance between the individual locking elements of the locking means specifies the individual, possible adjustment steps for the connecting element. In addition to the arrangement of the inventive connecting element on a support, the connecting element can be mounted with one of its legs on a substrate, such as a floor, a wall or a ceiling of a building, and serve as a connection for the carrier on this substrate. With suitable fasteners, the assembly of the connecting element on different materials, such as concrete masonry, natural stone and the like, possible. According to the three-dimensional shape of the construction to be created, the legs are angled to each other. Preferably, the connecting elements are a few standard parts covering the main types of connection used.

In order to be able to arrange the connecting element over the entire length of the carrier, the length of the at least one elongated hole corresponds at least to the sum of the distance of the openings in the outer wall of the carrier and the clear width, or the diameter of these openings. Thus, a stepless, along the screening of the locking means tuned adjustment of the connecting element is provided on the carrier. For large loads, the connecting cross section of only one fastener is often not sufficient to remove the load through the connection. To increase the connecting cross section therefore two or more fastening means are provided. If no adjustment possibility of the connecting element on the carrier is required, a maximum of two fastening means can be arranged in the previously described embodiment of the elongated hole. For example, to place two fasteners and still be able to position the fastener along the full length of the wearer in the preferred manner, the minimum length of the appropriate slot corresponds at least to the sum of twice the distance of the holes in the wearer's outer wall and the clear Width, or the diameter of these openings. If no adjustment possibility of the connecting element on the carrier is required, a maximum of three fastening means can be arranged in the previously described embodiment of the elongated hole.

In a preferred embodiment, all legs of the connecting element according to the invention have a slot. If the length of at least one leg is a multiple of the predefined spacing of the openings in the carrier, more than one slot can be provided on this leg. The remaining material portion between the slots improves the strength of the provided with two slots leg, compared to a provided with a long, continuous slot leg. To ensure the flexibility of the possible uses of the inventive connecting element latching means are provided in the region of all arranged slots. The first leg and the at least second leg preferably have a different length, which additionally increases the possible uses of the connecting element. If, for constructional reasons, the positioning of a connecting element at the height of the openings in the outer walls of the carrier is desired, one of the legs may have a slot instead of a slot, preferably the openings in the outer walls having the carrier corresponding, opening. This opening may have an area surrounding the opening with locking means, so that the counter-locking means of the fastening element can engage in this locking means.

Since the predefined distance of the openings in the carrier is preferably the same for all carriers and the openings are arranged on all outer walls of the carrier and the locking means of the connecting element locking elements having a predefined distance, the assembly and planning of the construction to be created is simplified. Measurement of distances for positioning of the connecting elements and special adjustments of the connecting elements are reduced to a minimum. An adaptation to the planning, a subsequent change and an extension of the construction is possible at any time. In addition, a simple disassembly of the construction and the reuse of the individual components is given. When the fastener is released or removed, the fastener may be reused at a different position of this or other construction.

Preferably, the second leg is aligned substantially perpendicular to the first leg, wherein optionally both legs each have at least one slot and at least over the length of the at least one slot locking means. The connecting element is formed in this embodiment as an angle element. A leg of the connecting element is arranged for example on a vertically oriented carrier and positioned by means of the locking means to the desired height. The carrier to be connected to the vertically oriented carrier is placed on the second leg and fixed. If the second leg of the connecting element likewise has a slot, the assembly of the carrier to be connected is substantially simplified since component and component tolerances can be compensated. If the region of the oblong hole of the second leg additionally provided with a locking means, a temporary support is ensured by the positive connection to the final fixation of the carrier to be connected to the vertically aligned carrier during the entire assembly process by means of engaging in the latching means Gegenrastmittels. In addition to the advantageous installation, the safety for all parties involved in the construction to be created at the same time improved. This connecting element is particularly advantageous for constructions that are created in the so-called framework. If the system carriers described above are used to create the construction, the connection element can be arranged at any height and in any direction of the system carriers. Any designs of three-dimensional constructions are possible.

The angle-shaped connecting element can for example also be used as a connection of a carrier to a substrate, as a so-called foot element for the construction, wherein preferably at least two connecting elements for fixing the carrier are arranged on the substrate. Depending on a connecting element z. B. on the opposite outer sides of the carrier or a respective connecting element is provided on at least one of the outer sides of the carrier in the X and Y axis of the carrier.

Advantageously, the second leg is designed as a connection element, wherein the connection element is made of a profile section, preferably of a hollow profile section, and the connection element has openings for fixing a carrier by means of fastening means, which can be passed through the openings in the connection element. The connecting element is designed in this embodiment as a substantially self-supporting bracket. The first leg is attached as already stated on a first carrier or a substrate. If the first limb is fixed, for example, to a vertically oriented support, an end-side connection of the support to be connected to the vertically oriented support can be created. The length of the connection element depends on the loads to be transferred. Preferably, at least two fastening means are provided for fixing the carrier to be connected to the connection element. In addition to the preferred production of the connection element from a hollow profile section, the connection element may have a U-shaped configuration, wherein the legs of the U-shaped connection element comprise, for example, a web or flange of the carrier to be connected. Next profile sections of an L-shaped profile or a flat steel can be arranged as a connection element. Preferably, a pair of these profile sections in the X and Y direction of the carrier to be connected is preferably provided on the first leg of the connecting element, for. B. by means of a weld. The configuration of the connection element is essentially dependent on the cross-sectional shape of the carrier to be connected and the existing loads.

Preferably, the connecting element has a third leg, wherein the third leg is optionally arranged in the same plane as the first leg, at least one slot and at least over the length of the at least one slot locking means, into which counter-locking means of a fastener can be brought into engagement. The first leg and the third leg form the so-called base plate of the connecting element, which can be connected to a carrier or on a substrate. The carrier to be connected is fastened to the second leg. With the size of the base plate and the axis distance of the fastening means, this embodiment of the connecting element has better leverage ratios than a two-legged version of the connecting element on. Higher torque forces can be transmitted via the connecting element to the first carrier or to the ground, for which reason this connecting element is particularly suitable as a foot element of a construction. With the elongated holes arranged in the first and third legs, the fastening means guided through these slots can be positioned corresponding to the openings in the first carrier or in the ground. If the connecting element is arranged, for example, on a vertically oriented carrier, the latching means provided in the region of the oblong holes prevent unintentional slipping of the positioned connecting element and make assembly much easier. In this case, for example, in the third leg provided with the counter-locking fastener can be provisionally passed through the slot and one of the openings of the carrier for temporary support of the connecting element and the at least one, further fastener without additional support or support of the connecting element during this setting process by the slot of the first leg and the corresponding opening in the carrier are passed.

Preferably, the outer contour of the connecting element is formed substantially complementary to the inner contour of the carrier, so that the carrier is slidable over the connecting element, whereby the carrier to be connected is already held provisionally in this assembly step. If the carrier to be connected is a hollow-profile system carrier with a substantially rectangular cross-sectional shape, the connection element preferably has a rectangular cross-section whose outer dimensions are preferably only slightly smaller than the inner dimension of the hollow profile system carrier. The fastening means is preferably braced to partial deformation of the pushed over the connecting element carrier, so that there is a positive and non-positive connection and a game is taken out of the connection.

In a variant according to the invention, the inner contour of the connecting element is formed substantially complementary to the outer contour of the carrier, so that the carrier can be inserted into the connecting element. Also in this embodiment of the connecting element, the carrier to be connected is already provisionally held in this assembly step. The connecting element has, for example, a rectangular cross-section whose internal dimensions are only slightly larger than the external dimensions of the carrier to be connected. If the carrier to be connected is a system carrier, the inner contour of the connection element can be designed to be complementary to the outer contour of the system carrier. The fastening means is preferably up clamped to the partial deformation of the connection element, so that there is a positive and non-positive connection and a game is taken out of the connection.

Preferably, the connection element has a substantially rectangular configuration, wherein the connection element has an X and Y axis in cross-section with respect to its center of gravity. The parallel aligned outer walls of the connecting element have opposite openings, so that the fastening element can be passed through the connecting element and the carrier to be connected. Each of the outer walls of the connecting element are preferably provided with openings for attachment of the carrier to be connected. The openings for the passage of the fastening means are arranged substantially parallel to a plane which is formed by the first leg of the connecting element and preferably have a configuration which prevents a twisting of the fastening means during bracing of the fastening means without the use of a counter-holding means. If the connection element is a solid profile, instead of a through opening, a bore can be provided which has an internal thread for arranging a screw as a fastening means. Furthermore, in the case of a connecting element made of a hollow profile, the opening in its outer wall can be provided with an internal thread for engagement of a screw as fastening means. The opening may also be provided with a collar which allows the arrangement of a sufficient number of threads to ensure the connection. As a variant of this, a nut for receiving a screw can be welded as fastening means on the inside of the connection element made of a hollow profile at the openings.

Preferably, several, optionally aligned perpendicular to each other, openings are provided in a plurality of mutually parallel planes. In the case of an end-side connection of a carrier, fastening in at least two axes is preferred for reasons of the load which is usually present and for structural reasons. The section of the connecting element therefore preferably has a length, so that at least one fastening means in the X direction and at least one fastening means in the Y direction, in each case based on the cross section of the connecting element, can be provided. With the crosswise and the preferred positive and non-positive connection of the connected to the connection element carrier is fixed in all degrees of freedom. In a variant of this, the connecting element has slots in its longitudinal direction on the outer walls, which simplifies the alignment of the carrier to be connected to the connecting element, since the fastening means can be infinitely positioned. A positive connection of the compound is not given. The ends of the slots prevent slipping of, connected to the connection element carrier when the forces acting on the connection for these are too large.

Advantageously, the locking means are arranged on the side facing away from the carrier of the leg. The connecting element can slide during displacement along the carrier on the outer surface. A fastening means having a counter-locking means is passed after reaching the desired position of the connecting element on the carrier through the opening of the connecting element and the one or more openings of the carrier and fixed by means of clamping the fastening means. In a first variant of this, the latching means may be provided on the side of the leg facing the carrier or the ground. When bracing the fastener, the locking means is pressed into the surface of the carrier, or the substrate and creates a positive connection. In a further variant, the support may preferably have the counter-locking means over its entire length, in which engages the locking means arranged on the side of the leg facing the support and thus enables the creation of a positive connection.

Preferably, the locking means comprise a toothing, wherein the tooth pitch of the toothing is preferably 2.5 mm. With this division, individual rest steps of 2.5 mm or a multiple thereof are possible. This design of the locking means covers a large part of the occurring in practice, design requirements for the execution of a Montagesys-tems. The toothing is preferably matched to the desired Verstellraster and the existing load. This results z. B. the required number of engaged teeth of the teeth of the locking and counter-locking means, the geometry, the width and the depth of the arranged teeth. If, for example, a finer graduation of the grid resulting from the latching and counter-latching means is desired, the pitch of the latching and counter-latching means can be reduced. For large loads, the pitch of the locking and counter-locking means z. B. also enlarged and formed with a deeper configuration of the teeth. For example, the latching means is a so-called prism toothing. Other ways to form the locking means are arranged on a leg racks or spaced wells, such. B. grooves and the like.

According to the invention, the connecting element has at least one bead. With the bead, a maximum rigidity of the connecting element is achieved with a minimal use of material. In other words, with a certain material thickness of the leg, a higher load can be taken over by this, as it is possible, for example, in a flat configuration of the leg.

According to the invention, the toothing is arranged in at least one of the bead walls of the at least one bead. The teeth can be rolled or embossed on the bead wall. By this machining operation, the material of the connecting element is compressed in the region of the toothing, which leads to an increase in the strength. For the engagement of the counter-locking means and to provide a positive connection, the available surface of the bead walls usually sufficient so that a secure attachment of the connecting element and, connected by these connecting elements carriers is ensured.

Preferably, the locking means are parallel to each other, transverse to the at least one slot. If the connecting element is arranged, for example, on a vertically oriented support, the load is applied transversely to the orientation of the locking means. In particular, in a combination of a toothing transversely to the direction of force and arranged on the side facing away from the carrier toothing and a communicating with the locking means geometry of the rear grip part results in a secure, positive connection that allows a finingerasterte positioning of the connecting element on the carrier.

Advantageously, the outer contour of at least one leg is complementary to the outer contour of at least one, connectable to the connecting member carrier. System carriers of a mounting system often have contoured outer surfaces. Despite a minimal material thickness, high loads can be absorbed by the connecting element. The leg formed complementary to the outer contour lies flat against the outer contour of the system carrier. When mounting the connecting element on the first carrier is given by the interlocking configuration of the two elements a guide, which facilitates assembly.

Preferably, the fastening element for fastening the connecting element to a carrier comprises a screw means with a rear engagement part, wherein the rear engagement part comprises the counter-locking means, and wherein the counter-locking means optionally comprises a toothing. The rear engagement part is, for example, a separate metal plate, which has the counter-latching means corresponding to the latching means. The rear grip part may further be a washer or a screw head on which the counter-locking means formed directly is. Preferably, the rear grip part is rotationally engaged with the screw means or is connected to this fixed, for example, insoluble. By the engagement of the locking means with the counter-locking means, the screw means is held against rotation during clamping of the same. To guide the screw means when placed in the openings of the connecting elements and the carriers connected by these guide surfaces can be provided on the screw, which allow a predefined leadership of the screw already during the setting process. For example, the openings in the carriers are formed as square holes. The screw means therefore preferably has plane surfaces which are matched to these square holes in the carriers. The width of the slots provided on the connecting elements, in this embodiment, preferably corresponds to the clear width of the square holes.

Preferably, the fastening element comprises a spring-loaded pressure mechanism for clamping the fastening element with the connecting element. A spring element is preferably arranged between a nut and the side of the carrier on the screw means, which is opposite to the side of the carrier on which the connecting element is arranged. The spring element is for example a spiral spring, a leaf spring, a conically wound spring or the like. The spring element is provided on the guided through the openings of the carrier part of the fastener, before arranging the nut for clamping the fastener on the support. Before the final fixation of the, to be arranged on the carrier connecting element, the element formed as a rear engagement part and provided with the counter-locking means can be lifted from the locking means of the connecting element by pressure on the nut. With a one-handed movement, the connecting element can be repositioned. By releasing the nut of the fastener, the counter-locking means engages in the locking means and the connecting element is held on the carrier. The attachment means can be designed in a variant of this, such as so-called quick release nuts, which can be inserted into corresponding openings in the connecting element or in the carriers. Such quick-release nuts are formed, for example, like quick release nuts of installation systems for pipe fittings on C-shaped mounting rails.

Ways to carry out the invention

Fig. 1 shows a perspective view of a first, not embraced by the invention embodiment of a connecting element. The angle element 1 is formed unequal-shaped and comprises a first leg 2 and a second leg 3, wherein the first leg 2 has a length which is longer than the length of the second leg 3. The angle element is made for example of a flat steel or sheet metal as a punched / bent part. In the first leg 2, a slot 4 is arranged, whose minimum length corresponds to the sum of the length of twice the distance between the openings in the carrier, on which the first leg 2 is arranged, and the clear width of the opening of the carrier. Preferably, the carriers described are system carriers for a mounting system. The carriers have for example openings in the form of a square hole with a clear width of 13.5 mm and a grid spacing of the openings of 50.0 mm. The length of the slot 4 is approximately in accordance with the above conditions 115.0 mm, which in the slot 4, two fasteners can be arranged.

In the second leg 3, a slot 5 is also provided, the minimum length of the sum of the length from the distance of the openings in the carrier, on which the second leg 3 is arranged, and the clear width corresponds to the opening of the carrier. Preferably, the same type of support is used throughout the design to be created. Thus, a smaller number of different components for the construction to be created is needed, which has an advantageous effect in storage and installation. The length of the slot 5 is in accordance with the above conditions about 65.0 mm, which can be arranged in the slot 5, a fastener. The width of the angle element 1 preferably corresponds at most to the width of the outside of the carrier on which the angle element 1 is arranged. Does the carrier in cross-section different dimensions, z. B. two angle elements with different, tailored to the dimensions of the carrier cross-section widths available or on the outside with the larger dimension an angle element is provided with a width corresponding to the shorter dimension of the carrier cross-section.

At the, the slot 4 and the slot 5 surrounding surface areas, the locking means 6 and 7 are formed in the counter-locking means of a fastener can be brought into engagement. The angle element 1 is z. B. used for a right-angled connection of a vertically and a horizontally oriented carrier. Since the load in such an application of the angle element 1 in the vertical direction is usually greater than in the horizontal direction of the construction, the first leg 2 is preferably arranged on the vertically oriented support, whereby two fastening elements for fixing the angle element 1 can be arranged on this support , The compared to the arrangement of only one fastener enlarged connection cross-section allows removal of higher loads.

For fixing the angle element 1 to the vertically oriented carrier, the angle element 1 is roughly positioned on the outside of the carrier at the height at which the other carrier adjoins. A first, provided with a counter-locking fastener is pushed through the slot 4 and through the openings on the outside of the carrier. A possible embodiment of a fastener is detailed in the Fig. 6 described. Before the final tightening of the fastener, the angle element 1 is aligned to the exact height and the second fastener in the same manner in the slot 4 and passed through the openings in the outer wall of the carrier, which leads to the openings in the outer wall of the carrier are adjacent to the first fastening element. The support resting on the second leg 3 of the angle element is fastened to the angle element 1 after it has been aligned by means of a further fastening element, which is passed through the oblong hole 5 and through the openings in the outer walls of the support.

The latching means are formed for example as prism teeth and have in this embodiment, a tooth pitch t of 2.5 mm. With the combination of elongated holes 4 and 5 formed openings of the angle element and the engageable latching and counter-locking means, the angle element 1 can be gradually shifted in a grid of, for example, 5.0 mm along the carrier, although the carrier has a grid spacing of the openings of 50.0 mm. This training covers the constructions usually created in practice.

In Fig. 2 is a perspective view of a second, inventive embodiment of a connecting element shown. Like the angle element 1, the angle element 11 is unequal in shape and comprises a first leg 12 and a second leg 13. The angle element 11 also serves to connect two system carriers of a mounting system, which have the previously described arrangement of the openings in their outer walls. The length of the slot 14 in the first leg 12 is therefore about 115.0 mm. The length of the elongated hole 15 in the second leg 13 is about 65.0 mm. On the first leg 12, a bead 16 and on the second leg 13, a bead 17 is formed. The system carrier has depressions on its outer walls, for example. The beads 16 and 17 are preferably complementary to the recesses in the outer walls of the carrier, so that the angle member 11 fixed to the carriers rests completely against the surface of an outer side of the carrier. At the Sickenwandungen 18.1 and 18.2 and at the Sick walls 19.1 and 19.2, the locking means 20 and 21 is formed by rollers. In the locking means 20 and 21 engage the counter-locking means of the fasteners.

A plan view of a third, inventive embodiment of a connecting element is in the Fig. 3 shown. The Stirnanbindeelement 31 comprises a base plate 32 and a connecting element 33. The to be connected to the Stirnanbindeelement 31 carrier is pushed over the connecting element 33 and fixed thereto with fastening means. The outer contour of the connecting element 33 is substantially complementary to the inner contour of the carrier to be connected. The base plate 32 has two elongated holes 34 and 35 for attachment of the Stirnanbindeelements 31 on a system carrier described above, wherein the arrangement of two fasteners in a respective slot 34 and 35 whose length, analogous to the above statements, is about 115.0 mm. The connecting element 33 is welded between the oblong holes 34 and 35 on the base plate 32. On the base plate 32, a bead 36 is formed over its entire length, which is preferably complementary to at least one of the outer contours of the carrier on which the Stirnanbindeelement 31 is arranged. The locking means 37.1 and 37.2 of the Stirnanbindeelements 31 are formed on the bead walls. If the face-binding element 31 is used as a foot element of a construction, for example for placement on a concrete floor, the bead 36 in the base plate 32 is dispensed with, so that the face-binding element 31 rests flat on the concrete floor.

Fig. 3a shows a detail of the Fig. 3 , The formed on the bead wall of the bead 36 locking means 37.2 has a tooth pitch t of 2.5 mm, which allows the counter-locking means of the fastener a grid adjustment of the Stirnanbindeelements 31 of 2.5 mm or a multiple thereof.

In Fig. 4 is shown a side view of the formed according to the third embodiment of the connecting element. In the connection element 33 a plurality of openings 41.1 to 41.4 are provided, through which the fastening means for fixing the connection element 33 are passed to the carrier to be connected. The openings 41.1 to 41.2 are formed as square holes and have the same inside width as the openings in the carriers. The distance between the openings 41.1 to 41.4 is 25.0 mm, which corresponds to half the distance of the openings in the outer walls of the carrier. Since the carrier on its outer sides offset from each other arranged openings at a distance of 50 mm, which passed through the openings in the X and Y direction of the carrier fastening means can not interfere with each other. If at each opening 41.1 to 41.4 in the connection element 33 there is a passage of fastening means in the X and Y direction of the carrier, the carrier can be provided with additional openings in its outer walls corresponding to the spacing of the openings 41.1 to 41.4.

Fig. 5 shows a longitudinal section of the connecting element formed according to the third embodiment along the section line VV of Fig. 3 , The connecting element 33 has openings (for example 41.1, 41.3, 51.2, 51.4, 52.1, 52.3) on all four outer walls 53.1 to 53.4. In the openings 41.1 and 52.1, or 41.3 and 52.3, the fastening means 54.1 and 54.2 are arranged in the X direction of the connection element 33. In the openings 51.2 and 51.4 and, not shown in this illustration, arranged in the outer wall 53.4 openings, the fastening means 55.1 and 55.2 are provided in the Y direction of the connecting element 33. The fastening means 54.1 comprises a threaded rod 56, at the ends of each a nut 57.1 and 57.2 is arranged for bracing the fastener 54.1. The fastening means 54.1, 54.2, 55.1, 55.2 are identical in this embodiment. With the crosswise arrangement of the fastening means 54.1, 54.2, 55.1 and 55.2 a positive and non-positive, advantageous connection for the carrier to be connected with the Stirnanbindeelement 31 is created.

A plan view of a fourth, inventive embodiment of a connecting element is in the Fig. 6 shown. The Stirnanbindeelement 91 comprises a base plate 92 which is formed substantially like the base plate 32 of the Stirnanbindeelements 31, and a connection element 93. The to be connected to the Stirnanbindeelement 91 carrier is pushed over the connection element 93 and fixed thereto with fastening means. The connecting element 93 comprises four connecting flanges 94.1, 94.2, 95.1 and 95.2, which are manufactured from flat steel sections. In each case, the opposing connection flanges 94.1 and 94.2 or 95.1 and 95.2 are identical. The outer contour of the connecting element 93 is substantially complementary to the inner contour of the carrier to be connected. The connection flanges 94.1, 94.2, 95.1 and 95.2 of the connection element 93 are welded between the oblong holes on the base plate 92. As on the connecting element 33, a plurality of openings are provided in the connecting flanges 94.1, 94.2, 95.1 and 95.2 of the connecting element 93, through which the fastening means are passed for fixing the carrier to be connected to the connecting element 93.

In the Fig. 7 a view of a fastener is shown. The fastening element 61 comprises a screw 62, which has a rear engagement part 63 integrally formed on one end and a threaded portion 64 at the other end. The fastening element 61 is guided for fastening a connecting element 65 through its oblong hole 66 and the opening 67.1 in the outer wall 68.1 of the carrier as well as through the opening 67.2 in the outer wall 68.2 of the carrier. The counter-detent means 69.1 and 69.2 arranged on the rear engagement part 63 engage in the detent means 70.1 or 70.2 arranged on the connection element 65 and create a positive-locking connection. As an anti-rotation and to guide the fastener 61, the screw 62 has a complementary to the configuration of the opening 67.1 designed guide portion 71.

At the threaded portion 64 of the screw 62 a, a leaf spring comprehensive spring element 72 is placed and a nut 73 is screwed. The spring element 72 is designed such that it can be arranged, for example, in a recess of the contoured outer surface of the outer wall 68.2. If the fine positioning of the connecting element 65 to take place, is by pressing the nut 73, the rear grip part of the lifted positive connection with the connecting element and the connecting element can be moved with one hand. If the nut 73 is released, engage the counter-locking elements 69.1 and 69.2 in the locking elements 70.1 and 70.2 and restore the positive connection forth. The connecting element 65 is held in its position. If this position coincides with the desired position of the connecting element 65, the fastening element is clamped to the nut 73 and the connecting element 65 is fixed to the outer wall 68.1 of the carrier.

A view of a rear engagement part of the fastener is in the Fig. 8 shown. The rear grip part 63 has a rectangular configuration and is fixedly connected to one end of the screw 62. At two mutually parallel edges 81.1 and 81.2, the counter-locking means 69.1 and 69.2 are formed, which engage in the locking means of the connecting element.

In summary, it should be noted that a connecting element has been created for a mounting system, which ensures a simple and flexible mounting of the carrier to be connected to the mounting system, as well as subsequent changes and additions to the created construction. A large number of previously complex designs can be created with a few standardized individual parts. Most connections can be made in a one-man assembly with a high level of installation comfort and eliminates the use of special tools or machines.
