    Description: The invention relates to a connecting device according to the preamble of independent claim 1.
    The present invention is intended to create a device for releasable connection of hollow profiles that is simple both in terms of construction and in terms of handling. In particular, the connecting device should enable a simple corner connection of hollow profiles.
    The solution to this problem on which the invention is based consists in the connecting device according to the features of independent claim 1.
    Further expedient and particularly advantageous embodiments of the connecting device according to the invention are the subject of the dependent claims.
    The essence of the device according to the invention consists in the following: A connecting device for hollow profiles comprises two clamping elements for insertion into one of two hollow profiles to be connected. The clamping elements each have a fixed wedge part with a first wedge surface and a movable wedge part with a second wedge surface and a tension screw. The two fixed wedge parts are connected to each other and the two movable wedge parts can be adjusted relative to the fixed wedge parts by means of the clamping screws, the second wedge surface of a movable wedge part sliding on the first wedge surface of a fixed wedge part.
    The adjustment of the movable wedge parts in a first direction relative to the fixed wedge parts results in a spreading of the wedge parts transversely to their direction of adjustment, so that they are clamped in the hollow profiles. The clamp connection can be released again by adjusting in the opposite direction.
    Advantageously, the fixed wedge parts and the movable wedge parts each comprise two parallel plates, each of which is held at a mutual distance by at least one preferably bolt-shaped spacer. This leads to a simple construction of the connecting device.
    [0008] The spacers are advantageously designed as flat spacer plates. The flat spacer plates are advantageously provided with projections which engage in receiving openings provided in the plates.
    Advantageously, the spacers (about perpendicular to the plates axes) are rotatably mounted in the plates. This prevents the clamping screws from jamming when they are tightened.
    Advantageously, the spacers have at their two longitudinal ends cylindrical pins which engage in receiving holes provided in the plates. This is a structurally particularly simple positive connection between the spacers and the plates.
    Advantageously, the clamping screws each connect a spacer of a movable wedge part with a spacer of a fixed wedge part. This is a structurally simple solution for the relative adjustment of the wedge parts.
    Advantageously, a first spacer with a through hole for the threaded shaft of a clamping screw and a second spacer with a threaded bore for the threaded shaft of the clamping screw is provided in each clamping element. This simplifies the assembly of the device.
    Advantageously, the spacers are each loosely arranged between two parallel plates, with spacers each provided with a through hole and spacers provided with a threaded bore being mutually interchangeable. This allows the tightening or loosening of the clamping screws from one side or the other, as required.
    For the production of immovable connections, the fixed wedge parts are expediently rigidly connected to one another or formed in one piece.
    For the production of profile connections with rounded corners or arcuate transitions, the parallel plates of the fixed wedge parts are advantageously connected to each other by arcuate plate sections.
    For the production of movable or articulated connections, the fixed wedge parts are expediently articulated together.
    [0017] The first and / or second wedge surfaces of the wedge parts can expediently also be designed in a stepped manner. As a result, the angle of the wedge surfaces can be reduced and the overall length of the clamping elements can be reduced. The reduction in the wedge angle has the consequence that the clamping force becomes greater and that from a certain wedge angle the parts wedge so much that they become practically unsolvable.
    Particularly advantageously, the movable wedge parts are each connected to the fixed wedge parts by means of webs, which are designed so that they allow a relative movement between the movable wedge parts and the fixed wedge parts. The webs preferably connect the parallel plates of the movable wedge parts to the parallel plates of the fixed wedge parts.
    CH 714 373 A2 Advantageously, two fixed plates, two movable plates and the webs connecting the movable plates to the fixed plates are each formed in one piece.

    The following convention applies to the following description: If not all parts in a figure are provided with reference numerals, reference is made to the respective other figures in connection with the respectively associated description parts. In the present context, hollow profiles are to be understood as meaning at least at one longitudinal end open tubular elements with, in particular, a rectangular or square inner cross section. Of course, hollow profiles with other cross-sectional shapes are also possible, as long as sufficient dimensional stability is ensured transversely to the longitudinal direction.
    According to the first exemplary embodiment shown in FIGS. 1-6, the connecting device comprises two clamping elements, designated as a whole with 10 or 20, which are adapted in terms of their outer dimensions to the inner cross section of the hollow profiles to be connected (FIGS. 3 and 4) , The two clamping elements 10 and 20 are firmly connected to one another and (here in the example) are at an angle of 90 ° to one another.
    The clamping elements 10 and 20 each have a fixed wedge part consisting of two parallel plates 11 and 12 or 21 and 22 and each also consisting of two parallel plates 13 and 14 or 23 and 24 existing wedge part movable relative to the fixed wedge part on. The parallel plates 11 and 12 or 21 and 22 or 13 and 14 or 23 and 24 are held by four bolt-shaped spacers 31, 32, 33 and 34 at a mutual distance, the distances of all plate pairs 11 and 12 or 21 and 22 or 13 and 14 or 23 and 24 are all the same size. The bolt-shaped spacers 31, 32, 33 and 34 are each provided at their two longitudinal ends with a cylindrical pin 31 a, 31b, 32a, 32b, 33a, 33b, 34a, 34b, which in continuous receiving bores 1 la, 12a, 13a, 14a , 21a, 22a, 23a, 24a in the plates 11, 12, 13, 14, 21, 22, 23 and 24 are loosely inserted, so that the bolt-shaped spacers are rotatably mounted about their pins in the plates. This can be seen in more detail in the sectional illustration in FIG. 2. In the remaining figures, the receiving bores and the pins of the spacers are only partially shown or only partially provided with reference numerals.
    CH 714 373 A2 The plates 11, 12 and 21, 22 of the fixed wedge parts and the plates 13, 14 and 23, 24 of the movable wedge parts each have a wedge surface 11b, 12b or 21b, 22b or 13b, 14b or 23b, 24b, wherein the wedge surfaces 13b, 14b and 23b, 24b of the movable wedge parts face the wedge surfaces 11b, 12b and 21b, 22b of the fixed wedge parts and slide against them.
    The spacers 31 and 33 in the plates 13, 14 and 23, 24 are each with a through hole 31c, 33c and the spacers 32 and 34 in the plates 11, 12 and 21, 22 are each with a threaded bore 32c , 34c. A clamping screw 41 or 42 extends through the through hole of the spacers 31 or 33 and engages with its threaded shaft in the threaded bore of the spacers 32 or 34. This can be seen in more detail in the sectional illustration in FIG. 2. In the remaining figures, the through holes and threaded bores in the spacers are not shown or are not provided with reference numerals.
    In Fig. 7, a tool W is shown in the form of a hexagon wrench with which the clamping screws 41 and 42 can be tightened or loosened. 1 and 2 and the above explanations immediately illuminate that by tightening the clamping screws 41 and 42, the spacers 31 and 32 or 33 and 34 are brought closer to one another, the movable plates 13, 14 and 23, 24 with their Wedge surfaces 13b, 14b or 23b, 24b slide on the wedge surfaces 11b, 12b or 21b, 22b of the fixed plates 11, 12 or 21, 22 and thereby an adjustment movement both in the longitudinal direction of the clamping screw 41 or 42 and transversely thereto perform. The clamping elements 10 and 20 are thus spread. 3 and 4, this is illustrated schematically on the basis of the plates 22 and 24. Fig. 3 shows the clamping element 20 in the unexpanded state, Fig. 4 shows the clamping element in the expanded state. By loosening the clamping screws 41 and 42, the spacers 31 and 32 or 33 and 34 are moved apart, the movable plates 13, 14 and 23, 24 again with their wedge surfaces 13b, 14b and 23b, 24b on the wedge surfaces 11b, 12b or 21b, 22b of the fixed plates 11, 12 or 21, 22 slide.
    To connect two hollow profiles P1 and P2, these are pushed onto one of the clamping elements 10 and 20 or the clamping elements 10 and 20 are inserted into one of the hollow profiles P1 and P2 to be connected. 5 shows the connecting device, the clamping element 20 being pushed into the hollow profile P1 (and therefore not visible). The hollow profile 1 is fastened to the clamping element 20 by tightening the clamping screw 42, which, as described above, causes the plates of the clamping element 20 to expand, so that the plates of the clamping element 20 are pressed against the inner wall of the hollow profile P1 or wedged with it and a clamp connection is created. Conversely, the clamp connection can be released again by loosening the clamping screw 42.
    In Fig. 6, two hollow profiles P1 and P2 to be connected to each of the clamping elements 10 and 20 are shown pushed. The clamping elements 210 and 220 located in the interior of the two hollow profiles P1 and P2 are shown in broken lines. As described above, the clamp connection is produced by tightening the tensioning screws 41 and 42 or loosened again by loosening the same.
    As shown in FIG. 1, the fixed plates 11 and 21 or 12 and 22 of the two clamping elements 10 and 20 are each formed in one piece. However, they can also be designed as separate parts and in some form (rigidly) connected to one another.
    Furthermore, in the exemplary embodiment shown, the two clamping elements 10 and 20 are mutually arranged at an angle of 90 °, so that the hollow profiles connected to the device are also at an angle of 90 ° to one another. Of course, the two clamping elements 10 and 20 can also be arranged at any other angle - in extreme cases also 0 ° - to each other.
    The spacers 31, 32, 33 and 34 are all identical on the outside and the plates 11, 12, 13, 14, 21, 22, 23 and 24 are only loosely on the pins 32a, 31b, 32a, 32b, 33a , 33b, 34a, 34b of the spacers 31, 32, 33 and 34. When assembling the connecting device, the spacers can therefore be interchanged as needed, i.e. a spacer with a through hole can be used instead of a spacer with a threaded hole and vice versa. 1, the (heads of) the tensioning screws 41 and 42 are accessible from above and from the left front. If the spacers were interchanged, the clamping screws would be accessible from below or from the rear on the right. Depending on the type and mutual configuration of the hollow profiles to be connected, one or the other of these variants can be more advantageous.
    Fig. 7 shows a second embodiment of the connecting device according to the invention. The only difference from the embodiment of FIGS. 1-6 is that the plates of the clamping elements are designed with stepped wedge surfaces. All other parts of this exemplary embodiment of the connecting device are the same as in the exemplary embodiment of FIGS. 1-6 and therefore each have the same reference symbols as in FIG. 1. The stepped wedge surfaces are, as can be seen in FIG. 7, with the reference symbols 111b, 112b , 112c, 113b, 114b, 114c, 122b, 122c, 124b and 124c. With regard to the mode of operation, this exemplary embodiment does not differ from the exemplary embodiment of FIGS. 1-6.
    The stepped design of the wedge surfaces of the wedge parts allows the angle of the wedge surfaces to be reduced and a smaller overall length of the clamping elements to be achieved. The reduction in the wedge angle has the consequence that the clamping force becomes greater and that from a certain wedge angle the parts wedge so much that they become practically unsolvable.
    CH 714 373 A2 [0034] FIG. 8 shows a third exemplary embodiment of the connecting device according to the invention. It comprises two clamping elements 210 and 220, which, in contrast to the embodiments described above, are not fixed or rigid, but are connected to one another in an articulated manner.
    The clamping elements 210 and 220 each have two fixed plates 211, 212 or 221, 222 and two movable plates 213, 214 or 223, 224 adjustable relative to these by means of clamping screws 41 and 42. In this respect, the clamping elements 210 and 220 do not differ in the basic structure and in the mode of operation from the clamping elements 10 and 20 according to the exemplary embodiments described above, so that no further explanations are required in this regard.
    The difference compared to the clamping elements 10 and 20 of the embodiments described above is that the fixed plates have tab-like extensions 251,252 and 261,262, respectively, the extensions 261 and 262 of the fixed plates 221 and 222 into a space between the extensions 251 and 252 of the plates 211 and 212 protrude. In the extensions 251 and 252 of the fixed plates 221 and 222, an elongated hole 253 and 254 are provided. A pivot pin 263, which is rotatably mounted in the elongated holes 253 and 254 and displaceable along this, extends through the extensions 261 and 262 of the fixed plates 221 and 222, so that the two clamping elements 210 and 220 are rotatable about the pivot pin 263 and thus pivotable relative to one another , In Fig. 8, the two clamping elements 210 and 220 are shown in an extended position in which the two clamping elements are in line (aligned), that is, they are not angled against each other. 9 shows the two clamping elements 210 and 220 in a position angled relative to one another.
    The hinge pin 263 is slidably arranged in the longitudinal direction of the elongated holes 253 and 254. As a result, hollow profiles connected by means of the connecting device can be pushed together in an extended (aligned) mutual arrangement and brought into mutual contact. To bend one hollow profile relative to the other hollow profile, one hollow profile is first pulled away from the other in the longitudinal direction of the other hollow profile and then pivoted by the desired angle.
    10-12 a fourth embodiment is shown, which differs from the embodiment shown in FIGS. 1-6 mainly by the cross-sectional shape of the hollow profiles designated here with P11 and P12. The clamping elements themselves are of the same design as shown in FIGS. 1-6. A clamping element is in the first hollow profile P11, the second clamping element is arranged in the second hollow profile P12 and is not visible in the illustration in FIG. 10.
    11 shows the cross-sectional shape of the hollow profiles P11 and P12. Each hollow profile roughly has a square outer contour with four side walls, with an outwardly open longitudinal groove being formed in each of the four side walls. Overall, this results in an X-shaped profile.
    The sectional view of FIG. 12 shows how the clamping elements are arranged within the hollow profiles P11 and P12. It can be seen that the plates 21 and 22 or 23 and 24 of the clamping element 20 are guided laterally on the side walls or the bottom walls of the longitudinal grooves of the hollow profile P12. Analogously, the plates 11 and 12 or 13 and 14 of the clamping element 10 are guided on the side walls or the bottom walls of the longitudinal grooves of the hollow profile P11, the latter, however, not being shown.
    The clamping elements can of course also be designed in combination with the hollow profiles shown in FIGS. 10-12 in accordance with the embodiments shown in FIGS. 7 and 8-9.
    13 shows a further exemplary embodiment, which differs from the exemplary embodiments illustrated in FIGS. 1-12 primarily by the design of the spacers. All other components of the device are the same as e.g. 1 and therefore provided with the same reference numerals as in Fig. 1.
    The connecting device again comprises two clamping elements, which are adapted in terms of their outer dimensions to the inner cross section of the hollow profiles to be connected (FIGS. 3 and 4). The two clamping elements are firmly connected and are (here in the example) at an angle of 90 ° to each other.
    The clamping elements again each have a fixed wedge part consisting of two parallel plates 11 and 12 or 21 and 22 and a respective wedge part also consisting of two parallel plates 13 and 14 or 23 and 24, movable relative to the fixed wedge part. The parallel plates 11 and 12 or 21 and 22 or 13 and 14 or 23 and 24 are held at a mutual distance by four here plate-shaped spacer plates 531, 532, 533 and 534, the spacing of all plate pairs 11 and 12 or 21 and 22 or 13 and 14 or 23 and 24 are all the same size. The spacer plates 531, 532, 533 and 534 are each provided on two opposite sides with tab-like projections 531a, 531b, 532a, 532b, 533a, 533b and 534a, 534b, which in receiving openings 511 in the plates 11, 12, 13, 14, 21, 22, 23 and 24 are loosely inserted. Analogous to the spacer bolts 31-34, two of the four spacer plates are each provided with a through hole and two with a threaded bore. A clamping screw 41 or 42 extends through the through hole of the spacer plates 531 or 533 and engages with its threaded shaft in the threaded bore of the spacer plates 532 or 534.
    CH 714 373 A2 It also applies to this exemplary embodiment that the fixed plates 11 and 21 or 12 and 22 of the two clamping elements are each formed in one piece. However, they can also be designed as separate parts and connected to one another in any form (rigid or articulated).
    14-16 shows a fifth embodiment of the connecting device according to the invention, which is constructed similarly to the embodiment of FIG. 13, but in which the plates of the fixed wedge parts are connected to the plates of the movable wedge parts by means of deformable webs are. All other components of the device are essentially the same as in the exemplary embodiment in FIG. 13 and are therefore provided with the same reference symbols as in FIG. 13.
    The connecting device again comprises two clamping elements, whose outer dimensions are adapted to the inner cross section of the hollow profiles to be connected (FIGS. 3 and 4). The two clamping elements are firmly connected and are (here in the example) at an angle of 90 ° to each other.
    The clamping elements again each have a fixed wedge part consisting of two parallel plates 11 and 12 or 21 and 22 and a respective wedge part also consisting of two parallel plates 13 and 14 or 23 and 24, movable relative to the fixed wedge part. The parallel plates 11 and 12 or 21 and 22 or 13 and 14 or
    and 24 are held at a mutual distance by four plate-shaped spacer plates 531, 532, 533 and 534, the spacings of all plate pairs 11 and 12 or 21 and 22 or 13 and 14 or 23 and 24 all being the same size. The spacer plates 531, 532, 533 and 534 are each provided on two opposite sides with tab-like projections, which are loosely inserted into receiving openings 511 in the plates 11, 12, 13, 14, 21, 22, 23 and 24. For the sake of clarity, the projections and the receiving openings are not provided with reference numerals in FIG. 14. Of the four spacer plates 531, 532, 533 and 534, two are provided with a through-hole and two with a threaded bore, in analogy to the spacer bolts 31-34 in FIGS. 1-2. As in the embodiment of FIG. 13, a clamping screw 41 or 42 extends through the through hole of the spacer plates 531 or 533 and engages with its threaded shaft in the threaded bore of the spacer plates 532 or 534. The clamping screw 41 is not shown in Fig. 14.
    Similar to the embodiment of FIG. 7, the wedge surfaces of the plates 11-14 and 21-24 are designed in stages, but here not in two stages but in three stages. On the plates 11, 13, 21 and 23 which are fully visible in FIG. 14, the three sections of the stepped wedge surfaces are designated by the reference symbols 111b, 111c, 111d, 113b, 113c, 113d, 121b, 121c, 121d, 123bc, 123c and Designated 123d. The corresponding reference numerals are not shown on the only partially visible plates 12, 14, 22 and 24 which are identical to the fully visible plates 11, 13, 21 and 23.
    The main difference of this embodiment of the connecting device according to the invention compared to the embodiments of FIGS. 1-13 is that the plates 11, 12, 21 and 22 of the two fixed wedge parts each with the plates 13, 14, 23 and 24 of the movable Wedge parts are connected, the fixed plates 11, 21 and 12, 22 each lying in one plane with the movable plates 13, 14 and 23, 24. The connection between a fixed plate 11, 12, 21 and 22 with the respectively assigned movable plate 13, 14, 23 and takes place by means of two webs. In Fig. 14 only the webs between the plates 11 and 13 or 21 and 23 are visible and there designated by the common reference numeral 600. The corresponding webs between the plates 12 and 14 or 22 and 24 are not visible. The webs are each arranged between two wedge surface sections.
    The fixed plates 11 and 21, the webs 600 and the associated movable plates 13 and 23 are integrally formed. The same applies to the fixed plates 12 and 22, the webs 600 and the associated movable plates 14 and 24. The entire connecting device thus consists of two levels of plate elements 11, 21, 600, 13, 23 and 12, 22, 600, 14, 24), the four spacers and the two clamping screws.
    The slightly curved webs 600 are designed to be deformable, so that they enable a relative movement between the plates connected via them, so that the movable plates with their wedge surface sections can be adjusted along the corresponding wedge surface sections of the fixed plates. As in all other exemplary embodiments, this is done by means of the clamping screws 41 and 42.
    The side view of Fig. 15 shows two movable plates 12 and 22 in the initial state of the connecting device before insertion into the hollow profiles (not shown here). This view corresponds to the oblique view of FIG. 14.
    The side view of Fig. 16 shows the two movable plates 12 and 22 in the final state of the connecting device after wedging in the hollow profiles (not shown here). The webs were deformed by the inward movement of the movable plates relative to the fixed plates.
    The main advantage of this embodiment of the connecting device according to the invention is that it consists on the one hand of fewer (a total of eight) individual parts and on the other hand that it is easier to handle. After the eight individual parts have been put together, they can be fixed in their mutual position by slightly tightening the clamping screws, so that the connecting device can be easily (pre) assembled and inserted as a whole into the hollow profiles to be connected.
    CH 714 373 A2 The connecting device according to the invention serves primarily as a corner connector for hollow profiles, the connection e.g. can also be articulated, as is explained with reference to the embodiment shown in connection with FIGS. 8 and 9. However, the connecting device is also suitable for the realization of round “corners”, two (e.g. straight) hollow profiles P21 and P22 being joined together at a distance and the distance being bridged by curved shaped pieces, as illustrated for example in FIG. 18.
    17 shows a further exemplary embodiment of the connecting device according to the invention, which is specifically designed for the implementation of such hollow profile connections with arc-shaped “corners”. Apart from a single difference, the connecting device of FIG. 17 is configured in the same way as the exemplary embodiment shown in FIG. 14, so that no further explanation is necessary. The difference to the exemplary embodiment of FIG. 14 is that the plates 11 and 21 or 12 and 22 are each connected by an arcuate plate section 1121 or 1222. The two hollow profiles P21 and P22 are clamped by tightening the clamping screws in the manner already described.
    18 shows how the space between the two hollow profiles P21 and P22 is bridged by two segment-shaped cover plates P23a and P23b. The segment-shaped cover plates P23a and P23b are screwed to the arcuate plate sections 1221 and 1222 (screws not shown).
    Of course, apart from the arcuate plate sections, the other parts of the connecting device can also be designed as described in the exemplary embodiments according to FIGS. 1 and 7.
