Description

[0001] The invention relates to a multiple fastening device with at least two differently designed sections for connecting the multiple fastening device to at least two elements or devices, wherein the multiple fastening device has at least one positive-locking connection section and at least one fastening section, wherein the at least one fastening section is provided for force-locking fastening of an element or device to the multiple fastening device and the positive-locking connection section of the multiple fastening device is connectable to another element, another device or another fastening device, as well as a fastening system for fastening at least two elements or devices to each other or to at least one fastening device, such as a bolt, or a rail element.

[0002] Multiple fasteners, as well as fastening systems for attaching at least two elements or devices to each other or to another fastener or a rail element, are known in the prior art. A multiple fastener, as defined here, is a fastener that has at least two sections, which are designed differently to allow connection to at least two elements or objects, e.g., rail elements. For example, such multiple fasteners are known in the form of sliding nuts, which enable the fastening of, for example, cables to rails. The sliding nuts are inserted into profile rails and are dimensioned accordingly to be slidably mounted within the profile rail.Furthermore, they feature a through-hole with an internal thread, allowing a clamp or other component to be attached via a screw connection, which in turn can be used to attach a pipe or cable. The sliding nut can also be equipped with a welded-on threaded bolt, onto which a pipe clamp or series clamp with a welded-on nut can be screwed. Thus, a connection section enabling a positive fit is always provided on the sliding nut. Solutions are also known in which lateral longitudinal grooves are provided in the base area of ​​a fastening element, allowing the fastening element to be inserted into a slot in a profile rail and slid onto the opposing legs of the profile rail.

[0003] Another embodiment of such a multi-point fastening device is known, for example, from DE 91 12 138 U1. This consists of a slider that can be slid onto mutually parallel sections of a profile rail and fixed to the profile rail by means of a clamping element, wherein the installation elements are either held on the slider or formed integrally with it. A so-called locking tongue is also held on the slider, the free edge of which rests against the surface of the mutually parallel sections of the profile rail, with the locking tongue forming an acute angle with the surface of the profile rail.

[0004] Also known are so-called hook-head screws, which engage with a C-profile rail with their projecting head and can thus be fastened within it. The screw section of the hook-head screw serves to fasten objects or other fasteners, which can be connected to the hook-head screw via the screw connection. One part of such a multi-purpose fastener, namely the hook-shaped projecting head of the screw, is therefore used for fastening to a profile rail, while the threaded part of the hook-head screw is used for fastening to any other object or fastener.

[0005] For example, EP 1 087 151 A2 discloses a fastening system, particularly for pipes or the like, on a ceiling or wall, comprising a holder and a threaded bolt onto whose free end a sliding nut can be screwed. This nut can be inserted into a C-shaped support rail and secured under preload to the slotted wall of the support rail by means of a clamping nut, a washer, and a spring element. The threaded bolt is permanently connected to the fastening element.

[0006] From CH 231 336 A, a fastening device for cable conductors is known, wherein it serves for slidable fastening to a C-shaped profile rail on which clamp bodies are slidably mounted, holding the conductor between them by means of lateral indentations. For the installation of pipe and measuring cables, moisture-resistant cables, and lamp cables, multiple clamps are known, which are mounted and fastened on row or U-rails by means of so-called sliding nuts, locknuts, or wedge-like nuts. According to this prior art, it is considered a disadvantage that the sliding nut, the screw, and the clamp body are three separate parts, and that the sliding nuts are threaded into the rail before the cables are laid, then the clamp body is placed on top and screwed on, or that the sliding nuts and clamp body are screwed together before installation and then threaded into place.According to this prior art publication, this disadvantage is overcome by each clamping piece body having a bore extending in the direction of the longitudinal axis, into which a thread is cut in the area of ​​the attachment piece, into which a screw inserted into the bore can be screwed until it rests on the web of the c-shaped rail and thereby clamps the attachment piece to the flange of the rail.

[0007] WO 2013 / 150 016 A1 also discloses a fastening arrangement with tolerance compensation, wherein the fastening arrangement serves to fasten a component B to a component A with self-adjusting tolerance compensation between components A and B. The fastening arrangement comprises a definable base element, which has a fastening screw that can be screwed in via a first thread pair, and an adjusting element with an external thread that can be screwed into the base element via a second thread pair. A first and a second anti-rotation device are provided between the base element and the adjusting element, which prevent the adjusting element from loosening from the base element during transport and from locking the adjusting element against the base element.

[0008] From DE 41 27 162 C1, a cable gland with a screw sleeve and a corresponding counter sleeve or union nut is known. The cable gland has a clamping insert with clamping fingers formed by slots, which, in the case of a plastic cable gland, are integrally molded onto the screw sleeve. Screwing the screw sleeve to the counter sleeve causes the clamping fingers to deform radially towards the cable via an annular pressure surface on the counter sleeve or union nut, or via a tapered shape in the screw sleeve or in the counter sleeve or union nut.At least part of the clamping fingers has two axially adjacent sections of different thicknesses. In a one-piece design of the screw sleeve, a thinner section adjoins the screw sleeve directly, while the thicker section, starting at the free end of the clamping insert, extends at its longest extent to the end of the slot. The clamping finger can still be bent with reduced force at the radially thinned wall at the end of the slot. The radial thickness of the thicker section of the clamping finger is at least approximately two-thirds of the dimension that extends between the core diameter of the screw sleeve thread and the corresponding thread of the counter sleeve or union nut, and the end face opening for the cable through the screw sleeve and counter sleeve—that is, the largest cable diameter.The clamping fingers can be recessed, hollowed out and / or profiled on their clamping or pressure surfaces and / or on their end face, which allows a seal projecting into this area to be well gripped and fixed, and better prevents unwanted retraction or deformation movement due to constriction, especially on smaller cable diameters.

[0009] DE 10 2014 008 166 A1 discloses a fastening device for attaching a mounting element to a threaded bolt, comprising a nut with a threaded bore and a clamping element with an opening that interacts with the nut. The nut has an outer conical bearing area with which, in the assembled state, it engages at least partially in the opening of the clamping element and rests there on a complementary inner cone that the clamping element has. The nut has at least one slot that interrupts the nut wall over a portion of its axial extent, the at least one slot opening at the axial end of the nut that is closer to the larger diameter than to the smaller diameter of the conical bearing area. The at least one slot extends from there over a length that is between 20% and 95% of the total axial length of the nut.The clamping element has an external thread in one section, which allows it to be screwed into a mounting element.

[0010] From JP 2005 121 154 A, a lock nut is known for providing a relatively inexpensive locking nut with a high locking effect when an object to be fastened in combination with a bolt is attached to vibrating points, such as a machine tool, construction machine, or transport machine. The lock nut consists of a nut body, an inclined seat surface, and a slot. The inclined seat surface is specifically designed on the underside of the nut body to have the required angle of inclination. Furthermore, the slot is formed on the upper surface of the nut body to divide the upper half of the nut body, allowing it to deform elastically.

[0011] The present invention is based on the objective of providing a multiple fastening device with at least one positive locking connection section and a fastening system in which the multiple fastening device can be used or is used, by means of which a high degree of modularity and speed is possible when fastening elements or objects, such as cables or pipes, or devices to a rail element or similar.

[0012] The problem is solved for a multiple fastening device according to the preamble of claim 1 in that the multiple fastening device is segmented in the area of ​​the positive locking connection section and the fastening section and wherein at least one clamping device is provided for exerting a clamping force directed at least towards the fastening section to change the opening width of an inner through-opening of the multiple fastening device and at least one spring element is provided for exerting a spring force directed opposite to the clamping force exerted by the clamping device, wherein the at least one clamping device and the at least one spring element interact together so that they hold together the segments of the multiple fastening device which is segmented in the area of ​​the positive locking connection section and the fastening section.For a fastening system according to the preamble of claim 9, the problem is solved in that at least one such multiple fastening element, with its at least one positive-locking connection section and / or its at least one fastening section, can be fastened or attached to one of the at least two elements or devices or to the at least one fastening element, or in or on the rail element. Further developments of the invention are defined in the dependent claims.

[0013] This creates a multi-fastening device by means of which, for example, pipes or conduits can be fastened to the fastening section of the multi-fastening device using a force-fit, in particular clamping, connection, while the positive-locking connection section of the multi-fastening device can be connected to another element, device, or fastening medium, in particular a rail element. Here, an element or device is understood to mean any element or device that is to be connected to one another via a positive-locking and / or force-fit connection. By providing a positive-locking connection section, it is possible for this section to engage positively with the rail element or to engage with a fastening medium and be held in or on it.Advantageously, the positive-locking connection section can be a polygonal connection section. Furthermore, particularly with a polygonal design of the positive-locking connection section of the multiple fastening element, longitudinal displacement of the polygonal connection section within the rail element, in particular at least one groove of the rail element designed as a profile rail element, especially a C-shaped profile rail element, is also possible.

[0014] Advantageously, the multi-point fastener with its polygonal connecting section can be slidably inserted into at least one groove of the profile rail element. Particularly with a C-shaped profile rail element, the polygonal connecting section of the multi-point fastener is held in place within the profile rail element by the positively engaging legs of the fastener. The polygonal connecting section can either be inserted laterally into the C-shaped profile rail element, with the fastening section of the multi-point fastener advantageously protruding from the C-shaped profile rail element and being used to fasten other elements, fixtures, fasteners, etc.

[0015] Particularly advantageous is the hexagonal design of the positive-locking or multi-sided connecting section in plan view, ensuring that two opposing sides of the multi-sided connecting section are always approximately parallel to each other and can thus be securely held between the typically parallel legs of the profile rail element. For example, the multi-fastener can have three segments forming the positive-locking connecting section and the fastening section; thus, three segments, each configured as a multi-sided connecting section in one section and as a fastening section in another. The segments are held together by the clamping device and at least one spring element.

[0016] A further advantage is that the positive-locking connection section and / or fastening section is provided with at least one internal thread. By providing such an internal thread, a screw connection is possible using, for example, a screw bolt as a fastening element, to which the positive-locking connection section of the multi-fastener engages in a positive-locking manner. Furthermore, an adapter or another system, such as a clamp, can be screwed in there for extension or directly. Thus, by providing an internal thread, a positive-locking or screw connection is possible with other elements or systems that have an external thread matching the internal thread of the positive-locking connection section.Depending on the design, the positive locking connection section thus enables, alternatively or cumulatively, an external positive locking connection when forming a polygonal profile and an internal positive locking connection through the internal thread.

[0017] The positive-locking connection section and the fastening section are advantageously formed as a single piece. Since individual segments held together by the clamping device and the at least one spring element are provided in the longitudinal direction of the multiple fastening element, it proves advantageous if the positive-locking connection section and the fastening section are formed as a single piece.

[0018] Furthermore, it is generally possible to detachably connect the segments of the multi-fastener, particularly in the transition area between the fastening section and the positive-locking connection section, for example, by means of a plug connection and / or screw connection and / or swivel connection and / or expansion connection, etc. If a detachable connection is provided for separating the fastening section and the positive-locking or multi-sided connection section, even greater differentiation and modularity regarding the design of the at least one fastening section and the at least one positive-locking connection section is possible. However, to ensure particularly fast connection with elements, devices, and / or rail elements, it proves advantageous to design the at least one fastening section and the at least one positive-locking connection section as already connected or as a single unit.

[0019] It is further advantageous if the segments of the multi-fastener and the at least one clamping device and / or the at least one spring element are detachably connected to one another. The clamping device and spring element can be arranged on the individual segments of the multi-fastener in such a way that subsequent detachment of the individual segments from one another is not possible, but of course, the distance between the individual segments, and thus the opening width of the inner through-hole of the multi-fastener, can be increased or decreased.The clamping device allows the distance between the individual segments of the multiple fastener to be reduced in both the fastening section and the positive locking connection section, while the action of the spring element, which is directed in the opposite direction to the clamping force of the clamping device, makes it possible to increase the distance between the individual segments.

[0020] An element, component, etc., to be attached to the multi-fastener can be connected to it by positive locking via at least one internal thread. Additionally, such an element, component, etc., can be clamped or secured using the clamping device of the multi-fastener. This enables a secure and quick connection between the multi-fastener and the element, component, etc., to be attached. The element, component, etc., may, but does not necessarily have to, have an external thread, as it can be held on the multi-fastener solely by the clamping device.

[0021] The clamping device can advantageously be designed in the form of a clamping ring which is arranged in the area of ​​the fastening section so as to be displaceable in the longitudinal direction of the multiple fastening element, so that the individual segments of the fastening section can be displaced against the acting spring force of the at least one spring element with respect to their distance to each other, i.e. the distance between the individual segments of the fastening section can be reduced.

[0022] The advantageous modular design of the multi-fastener allows the internally threaded positive-locking connection section and / or fastening section to be detached from the clamping device and the at least one spring element and replaced, in particular, with a different internal threaded positive-locking connection section and fastening section. This enables the multi-fastener to be adapted to different thread sizes of the elements to which it is to be connected. For example, the at least one internal thread of the at least one positive-locking connection section can be an M6, M8, M10, or M12 thread.Due to the fact that the multi-fastener is segmented, simple assembly and tolerance compensation are possible in a simple way, since such tolerance compensation can be achieved by varying the position of the clamping device, thus the distance left between the individual segments and therefore the opening width or clear width of the inner through-hole of the multi-fastener.

[0023] For example, this makes it possible to connect the multi-fastener to an adapter and / or clamp in the area of ​​the internal thread of its positive-locking or multi-sided connecting section, provided that the adapter, part of the clamp, or a part connected to it has an external thread. If these have no external thread or only a partial external thread, the threaded part can be positively connected to the internal thread of the positive-locking connecting section, while the remaining part is securely held by friction by the fastening section and / or positive-locking section equipped with the clamping device. This allows for the connection of a wide variety of elements, components, or devices to the multi-fastener, both at the fastening point of the positive-locking connecting section and at least one fastening section equipped with the clamping device and the spring element.In particular, the internal thread of the multi-fastening device allows for height adjustment of an element, component, or device received therein relative to a profile rail element to which this element, component, or device is to be attached, wherein the multi-fastening device is supported at least on or in the profile rail element and / or received in it.

[0025] The Fig. Figures 1 to 4c show an open position of a multi-point fastener 1, while the Fig. Figures 5 to 8c show a closed position of this. The multi-point fastener has three segments 10, 11, 12 around its circumference. In the longitudinal direction, the multi-point fastener has a polygonal connecting section 2 and a fastening section 3. An internal thread 20 is provided inside polygonal connecting section 2 and fastening section 3. As shown in particular by the Fig. 2, Fig. 3, Fig. 6, Fig. As can be seen from Figure 7, segments 10, 11, and 12 in the area of ​​the polygonal connecting section 2 are additionally marked with reference numerals 21, 22, and 23 to identify this section. Since, as can be seen in particular, Fig. Since the multi-sided connecting section 2 and the fastening section 3 are formed in one piece, the individual segments 10, 11, 12 of the multi-fastening device 1 are also formed in one piece.

[0026] To hold the individual segments 10, 11, 12 together even in the open position and to enable them to be moved from an open to a closed position, and vice versa, a combination of a clamping ring 4 and a spring element 5 is provided. These are particularly well suited to the Fig. 1 and Fig. 2, Fig. 4a, Fig. 4b as well as 5, 6, 8a and 8b. The clamping ring 4 surrounds the three segments 10 to 12 on the outside in the area of ​​the fastening section 3, while the spring element 5 is arranged inside the multi-fastener 1 in the area between the fastening section 3 and the polygonal connecting section 2. As shown in particular Fig. The spring element 5, which can be removed from section 2, is arranged in a groove 33 inside the fastening section 3 in an area where the fastening section 3 tapers conically on the outside. The tapered section 34 is arranged between two concentric circumferential surfaces of the multi-fastener 1. The clamping ring 4 rests on the circumferential surface with the smaller radius in the open position and on the circumferential surface with the larger radius in the closed position. The clamping ring 4 rests in the open position of the multi-fastener 1, as is particularly evident in the Fig. As shown in Figures 1 to 4c, the clamping ring 4 is moved over the tapered chamfer 34 onto the straight, annular section 24 of the multiple fastener 1 for stacking the segments 10 to 12 of the multiple fastener 1. The end position on the straight section 24 is the closed position, which is shown in the Fig. 5 to 8c is shown.

[0027] By providing the clamping ring 4 in conjunction with the spring element 5, it is thus possible to move the individual segments 10, 11, 12 of the multi-fastening device 1 towards each other and away from each other by sliding the clamping ring 4 from its position on the straight, annular section 35, over the tapered section 34, onto the straight, annular section 24. The open position of the multi-fastening device 1 is particularly advantageous to the Fig. 2 and Fig. 3 and 4a to 4c, while the corresponding Fig. Figures 5 to 8c show the closed position of the multi-fastener 1, in which segments 10, 11, 12 of the same are positioned with their lateral flanks 110, 111, 112, 210, 211, 212 closely abutting each other. The distance a between the lateral flanks of segments 10, 11, 12 of the multi-fastener 1 is changed by moving the clamping ring 4, as shown by comparing the Fig. 2, Fig. 3 and Fig. 6, Fig. 7 can be taken from the diagram. After the segments 10, 11, 12 have been completely brought together by moving the clamping ring 4 into position on the straight, annular section 24, the distance between the lateral flanks 110 and 211, 210 and 112, 111 and 212 of the segments 10, 11, 12 of the multiple fastening device 1 becomes approximately zero. This is particularly evident in the Fig. 6, Fig. 7 and Fig. 8a and 8c can be seen. By moving the clamping ring 4, an inner through-opening 13 of the multi-fastener 1 is changed, between a maximum clear width W max , as they are in Fig. 2 can be seen and a minimum clear width W min , as they are in Fig. 6 can be seen.

[0028] As in Fig. As indicated in Figure 6, the force F1 exerted by the clamping ring 4 acts in the opposite direction to the compressive force F2 exerted by the spring element 5. The compressive force F2 exerted by the spring element 5 pushes the segments 10 to 12 apart, while the force F1 exerted by the clamping ring 4, both in its position on the straight, annular section 24 and also when traversing the tapered section 34, acts in the opposite direction to the force F2, i.e., inwards with respect to the multiple fastening element 1. The segments 10 to 12 are held together by the clamping ring 4 and by the interaction of the spring element 5. However, it is also possible, for example, to provide segments with a different thread or internal thread 20, to replace the segments 10 to 12 with other segments that are, for example, without an internal thread or with a different internal thread.For example, common threads M6, M8, M10, or M12 can be provided. Of course, any other thread sizes and non-metric threads are also possible. The internal thread 20 allows the multi-fastener 1 to be connected, for example, to a bolt or another element, component, etc., with an external thread. In the area of ​​the fastening section 3, another element, component, etc., can be held in a force-fit or clamping manner. Alternatively, an element, component, etc., can be provided that has an external thread at one end that engages positively with the internal thread 20, and another section without a thread, which is then held in a force-fit, particularly clamping, manner by the fastening section 3. Furthermore, the combination of the internal thread 20 and the fastening section 3, which force-fits an element, component, etc., can also be used.It can accommodate multiple fastenings via the multiple fastening device 1 on different elements, components, equipment, etc.

[0029] Regarding the provision of the polygonal connecting section 2, as the Fig. 3, Fig. 4c, Fig. 7, Fig. 8a, Fig. 8c can be particularly well removed, e.g. in the design as a hexagonal connecting section, in particular the insertion of the multiple fastening element 1 into a profile rail element, such as a C-shaped profile rail element 6 with an internal groove 60, is possible. This is in Fig. 14 indicated. Here, the parallel outer side surfaces 100, 101, 102, 103, 104, 105 of the polygonal connecting section 2 are positioned, as shown in particular in Fig. 3 and Fig. 87 can be seen on the inside of the outer walls 61, 62, 63 surrounding the groove 60, or legs of the profile rail element 6. Various components or elements can be attached to the multi-fastener and thus connected to the profile rail element, such as a threaded rod, a pipe, etc.

[0030] Furthermore, it is possible, as in the Fig. Figures 10a to 10c and 11a to 11c show the use of the multi-point fastener 1 for height adjustment of a threaded rod 50, which is to be attached to such a profile rail element 6. The multi-point fastener 1 bears with its front surface 25 against a perforated plate 64, which in turn is supported on the outside of two legs 65, 66 projecting inwards into the groove 60 of the profile rail element 6. A sliding nut element 67 is arranged on the inside of the two legs 65, 66, thus in the groove 60, and is supported on the inside of the legs 65, 66. This is particularly advantageous in Fig. Figure 10b shows that a threaded rod 50 is received in the multi-point fastener 1 and extends through it into the interior of the profile rail element 6, into its inner groove 60, i.e., through the perforated plate 64 and the sliding nut element 67. The threaded rod 50 is held by the multi-point fastener 1, and the fastener 1 is held by the profile rail element 6 by its interaction with the perforated plate 64 and the sliding nut element 67. By providing such a connection, it is possible to move the multi-point fastener 50 longitudinally in the groove 60 of the profile rail element 6 while simultaneously holding the polygonal connecting section 2, and thus the threaded rod 50, to it, as shown. Fig. 10a to 10c, 11a to 11c and Fig. As can be seen in section 14. Even without a sliding nut, adjustment of the sliding nut element, primarily in the longitudinal direction of the profile rail element, and height adjustment with respect to the threaded rod and the profile rail element are possible. Furthermore, mounting the threaded rod to the profile rail element 6 is easy, since the multi-point fastener, in its open position, simply needs to be moved along the threaded rod to the appropriate position and then, by sliding the clamping ring, brought into its clamping or positive-locking, closed position, thus securely holding the threaded rod to the profile rail element.

[0031] The Fig. Figures 11a to 11c show an alternative embodiment for fastening the threaded rod 50 to the profile rail element 6. In this embodiment, instead of the perforated plate 64, a counter element 69 is arranged that encompasses the profile rail element 6 on its open side 68, which is provided with the two legs 65, 66. The multi-point fastener is supported on the outside of the counter element 69 with its front surface 25, while the sliding nut element 67 is supported against the legs 65, 66 in the groove 60 of the profile rail element 6. The profile rail element 6 is thus encompassed on the outside by the counter element 69, enabling a particularly stable hold of the threaded rod 50 on the profile rail element 6, oriented perpendicular to the open side of the profile rail element.

[0032] The Fig. Figures 12a to 12c show the hook-head screw 300, which is provided with a hook head at one end and with the multi-point fastener 1 along its longitudinal extent. A projecting hook head 301 of the hook-head screw 300 can be positioned on or engaging with a component, such as the profile rail element 6. By changing the position of the multi-point fastener 1 along a threaded rod section 302 of the hook-head screw 300, a clamping connection to the respective component, or in particular to the profile rail element 6, can be achieved through the interaction of the hook head 301 and the multi-point fastener 1, similar to the arrangement shown in the following figures. Fig. Figures 10a to 10c or 11a to 11c show such a hook head 301 can prevent rotation inside the profile rail element and thus provides a counter-position when inserting the hook head 301 into a profile rail element 6, particularly when the outer dimensions of the hook head 301 are dimensioned according to the inner dimensions of the profile rail element 6 between its outer walls 61, 62. The combination of the hook head screw 300 and the multi-fastener 1 can also be used advantageously in other applications besides with the profile rail element 6.

[0033] Before the multi-sided connecting section 2 is attached to such a profile rail element 6, the externally threaded element, component, etc., such as a threaded rod, a threaded rod section, or a bolt, is positively connected to the internal thread 20 of the multi-fastener 1 by interlocking and fastened to it. Furthermore, a bolt without an external thread or another element, component, etc., can be frictionally attached to the multi-fastener 1 via the fastening section 3. Height adjustment relative to the profile rail element 6 can be achieved via the internal thread of the multi-fastener 1, and sliding adjustment along the profile rail element is also possible via the multi-fastener when inserted into a profile rail element.By providing the multi-sided connecting section 2, this can engage and be held in place inside the profile rail element 6 instead of a conventional hook-head screw, allowing, for example, a bolt, threaded rod section, threaded rod, etc., to engage and be held in the fastening section 3. A suitably designed element can then be attached to the bolt, etc., or directly to the fastening section 3, just as with a hook-head screw. However, the assembly time of the multi-sided fastener 1 is significantly shorter than that of a hook-head screw.

[0034] Elements, components, etc., that can be connected using the multi-fastener 1 include, for example, clamps on profile rail elements, by means of which, for example, pipes, lines, cables are to be attached to them, or adapters for extending or connecting to the multi-fastener 1, whereby further elements, components, etc., can be attached to the adapters. As in Fig. As shown in Figure 13, a pipe 8 can be attached to the profile rail element 7 shown there by means of a U-bolt clamp 9. The U-bolt clamp 9 is attached to the profile rail element 7 by two multi-point fasteners 1, namely in the area of ​​the angled ends 90, 91 of the U-bolt clamp 9. Instead of such a U-bolt clamp 9, which attaches the pipe 8 to the profile rail element 7 from the outside, surrounding or encompassing it, another element, in particular another clamp, can be used, which, for example, is connected to the profile rail element 7 only at one point via the multi-point fastener 1. For fastening, the multi-point fastener 1 rests, in particular, on the U-bolt clamp 9 in the area of ​​its angled ends 90, 91, which are provided with a through-opening, whereby a threaded rod, which is in Fig. 13, which is not visible, passes through the inner through-opening 13 of the multi-fastening device 1, the respective openings 90, 91 of the U-bolt clamp 9, and an opening 70, which is provided along the profile rail element 7 in its outer sleeve, into the interior of the profile rail element 7. Inside the profile rail element 7, a sliding nut for locking can be arranged on the threaded rod, in particular loosely arranged, which, however, in Fig. 13 is not visible. Thus, for example, it is possible to use only the multi-fastener 1 to attach the U-bolt clamp 9 to the profile rail element via a threaded rod held in the multi-fastener, wherein the multi-fastener rests on the respective angled end 90, 91 of the U-bolt clamp 9 and the threaded rod extends through the opening therein and the opening 70 of the profile rail element 7 and is connected inside the profile rail element 7 with a nut or the aforementioned sliding nut. Through the U-bolt clamp thus attached to the profile rail element 7, for example, a pipe, such as the pipe 8, can be enclosed on the outside over its entire circumference and attached to it, thus enabling a connection between the profile rail element 7 and the pipe 8.

[0035] To attach a bolt to a profile rail element, such as a rectangular hollow profile element 40, as is done in Fig. As shown in 9, the multiple fastening device 1 can again be used. This can be, as shown in Fig. As indicated in Figure 9, the bolt is inserted through a corresponding opening 41 in the circumferential outer wall 42 of the rectangular hollow profile element 40. The multiple fastening element 1 is supported, in particular, on the outside of the outer wall 42 which has the respective opening 41, with the bolt to be fastened to it being encompassed by the multiple fastening element and received in its inner through-opening 13. The bolt can be a screw bolt that can be connected to the multiple fastening element 1 by screwing it into the internal thread 20 of the polygonal connecting section 2. If the bolt is not a screw bolt, but rather a bolt without an external thread, or with an incompatible or only partially external thread, it can be held clamped in the fastening section 3 of the multiple fastening element 1.A sliding nut can be arranged on the inside of the outer wall 42 of the rectangular hollow profile element to provide counter-holding when attaching the bolt to the outer wall 42 of the rectangular hollow profile element via the multi-point fastener. Accordingly, it is also possible to arrange the multi-sided connecting section 2 on the inside of the circumferential outer wall 42, i.e., inside the rectangular hollow profile element 40, whereby the bolt can be inserted from the outside into the fastening section 3 by clamping. Such an arrangement is shown in . Fig. 9 is also indicated, specifically in the upper left area. The ones in the Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13 to Fig. The 14 application possibilities shown for the multi-point fastener 1 can be used in the sanitary sector or in plant and mold construction.

[0036] The multi-fastener 1 can also be used advantageously in the construction industry, for example, when a threaded rod is cast into a concrete surface or element, protruding above the surface. The multi-sided connecting section 2 with its internal thread 20 of the multi-fastener 1 can be screwed onto the threaded rod, so that the fastening section 3 can be used for the quick fastening of further elements to the concrete element or surface.

[0037] This allows for a secure and quick connection of the multi-point fastener 1 to a wide variety of elements, components, etc., to be attached to it, whereby both the positive-locking or multi-sided connection section 2 with or without internal thread 20 and the force-locking, clamping, fastening section 3 can be used in conjunction with the clamping ring 4 and the spring element 5 for fastening. As particularly Fig. As can be seen from Figure 7, the polygonal connecting section 2 is specifically hexagonal, a shape that proves particularly advantageous for installation in profile rails due to the parallel outer side walls 100 to 105. The modular design of the multi-fastening device 1, namely its individual segments 10, 11, 12 comprising the polygonal connecting section 2 and the fastening section 3 in conjunction with the clamping ring 4 and spring element 5, allows for effortless and simple replacement of segments 10, 11, 12 to adapt to different applications.On the one hand, this allows for adjustments with regard to the internal thread 20, and on the other hand, with regard to the external and internal dimensions of the closed and open multi-fastener, its external and internal shape, and also by omitting the internal thread 20 if this is not required, but rather a longer clamping surface is needed for the clamping reception of one or more elements, components, etc. Thus, numerous variations are possible with regard to the segments 10 to 12, which are always held together by the clamping ring 4 and spring element 5 and can be positioned and separated.

[0038] The multi-point fastener 1, in particular its segments 10, 11, 12, can be made of a metal, a metal alloy and / or a plastic material, whereby any combination of materials can be provided for specific applications. If necessary, only individual surfaces can be made harder or softer, in particular by varying and combining the materials used.

[0039] In principle, it is not only possible to provide one-piece segments 10, 11, 12, but also to design the polygonal connecting section 2 and the fastening section 3 of each segment 10, 11, 12 to be detachable from one another, so that the segments 10, 11, 12 only come into being after the segments 21 to 23 are joined with the segments of the fastening section 3. Such a connection is possible, for example, by plugging, clamping, a swivel joint, etc. However, a one-piece solution for the segments 10, 11, 12, as shown in the Fig. 1 to 8c is shown.

[0040] In addition to the embodiments of multiple fasteners described above and shown in the figures, numerous other embodiments can be provided, each comprising at least one positive-locking connection section and at least one fastening section for the force-locking attachment of an element to the multiple fastener. The multiple fastener is segmented in the area of ​​its positive-locking connection section and its fastening section. Furthermore, at least one clamping device is provided for exerting a clamping force directed towards the fastening section to compress it, and at least one spring element is provided for exerting a spring force opposing the clamping force exerted by the clamping device.
