Definitions

  • the invention relates to a kit for a structure or scaffolding, in particular a truss structure, with struts, beams, supports or the like. Bars and with couplings for connecting at least two or more bars at corners, nodes or the like. Connection points of the supporting structure, coupling openings and coupling projections being releasably connectable to one another.
  • Spherical couplings are provided, which have a plurality of radially inwardly directed threaded holes as coupling openings. Threaded pieces protrude on the end faces of the rods, the threads of which fit into the threaded holes of the spherical coupling parts. By rotating these threaded parts relative to the bars, they can be screwed into these threads and thereby axially pushed out of the bars.
  • hexagonal sleeves are provided in a complex manner on the outside of the threaded projections, within which the threaded parts are mounted, these being rotatably connected to the sleeves, so that the rotation of the sleeve also causes entrainment of the screw part in the direction of rotation.
  • an axial guide between the sleeve and the threaded part is provided at the same time, in this way the threaded pieces are screwed into the screw holes of the ball couplings. Appropriate storage and mounting of the threaded pieces in the end areas of the rods is required.
  • the overall result is a relatively complex construction, in which, in particular, the assembly of a space frame with a large number of connection points and coupling parts is very time-consuming, since numerous screw connections have to be made. Disassembly is correspondingly time-consuming. This time requirement is particularly unfavorable when it comes to supporting structures that are only required for a relatively short time, for example for the design of exhibition stands, and that have to be assembled and dismantled accordingly often.
  • hammer head screws are provided at the front ends of the rods, the threads of which engage in a nut rotatably mounted on the end face of the rod.
  • the hammer-head-shaped end can be introduced into the coupling part in one orientation direction through an elongated hole coupling opening and anchored after rotation by 90 °. Then, by turning the nut mentioned, this hammer head screw is tightened relative to a sleeve located between the end face of the rod and the surface of the coupling part.
  • the inclined surfaces can thereby simplify the compression of the latching elements, but a corresponding force-consuming compression by the user is required during disassembly.
  • the compression-preventing locks In order to avoid unwanted loosening, the compression-preventing locks must be inserted in the coupling area, the removal of which is also time-consuming.
  • a correspondingly long slot is required at the end of the rod, which not only weakens this rod, but also results in an unsightly picture overall.
  • this type of coupling practically does not eliminate any play required within the coupling parts for their actuation, so that the overall construction does not permit the desirable rigidity.
  • kits There are also a number of other examples of such kits known, which are based more or less on a comparable principle and an extensive effort by experts to obtain a support structure with coupling points for the individual rods that can be set up safely.
  • the invention has for its object to provide a kit with rods and coupling of the type mentioned, in which the connection of the rods with the coupling part and the release can be carried out more quickly, but the forces occurring can still be transmitted well. At the same time, slitting of the rod ends should be avoided.
  • the coupling projection in the one position in which the recess and the retaining pin fit together can be inserted and automatically locked by the springing back of the retaining pin, while it is simply rotated by about 90 ° to disengage, whereby the coupling pin by the not recessed area of the coupling projection is in turn deflected, after which the coupling projection can be withdrawn again without any problems.
  • Coupling and uncoupling can therefore be carried out very quickly and easily. Due to the axially adjustable threaded or sliding sleeve, the respective coupling position can be fixed and a clearance important for assembly can be eliminated.
  • Screwing movements for fixing the coupling and for switching off its play for the actual coupling connection are of no importance, so that only relatively few rotations or even less than one rotation on the sleeve or a short sliding path can suffice. It is particularly expedient if two, preferably parallel, holding pins are provided in the coupling opening, if the coupling projection has a rounding, tapering or the like at its front end in the insertion direction. has, which can be inserted between the two retaining pins if or the like following the sharpening.
  • the axial dimension of the lateral recess of the coupling projection can be greater than the thickness of the retaining pin or pins and the adjustment path of the clamping, threaded sleeve or sliding sleeve can correspond to at least this difference in the dimension of the recess compared to that of the retaining pin or be greater.
  • This axially larger extension of the recess results in the desired axial play of the rod with respect to the coupling, so that such a rod can also be inserted with its two coupling ends between two coupling points and coupling parts.
  • the corresponding axial play can then be due to the corresponding sliding or Screw path of the clamping or threaded sleeve can be eliminated in the position of use.
  • This form fit between the recess and the retaining pin can be designed particularly inexpensively and yet effectively if the retaining pin or pins have a round cross section and the limitation of the coupling recess facing the insertion tip of the coupling projection from the outside or top of the coupling projection to the recess base - forming the undercut - runs obliquely at an acute angle to the recess base and is preferably rounded at the transition to the recess base, in particular with a radius of curvature which corresponds to the radius of the cross section of the retaining pin.
  • the retaining pin comes to rest under the tensile load of the clamping or threaded sleeve at this transition between the bottom of the recess and the lateral boundary of the coupling recess and is fixed there by the oblique course of the recess boundary.
  • the additional coupling part cooperating with the bars can be provided with an approximately spherical, ring-shaped, cross-shaped, angular, T-shaped or the like. Outside contour can be provided and the coupling counterpart interacting therewith can be arranged on the end faces of the rods.
  • a reverse arrangement would also be conceivable, in which the coupling opening with the retaining pins on the end faces of the rods and the coupling projections are provided on the coupling part, but this would result in a complex coupling part and possibly in the event that not all coupling points of this coupling part are required , the need for disassembly of the coupling projections.
  • the part having the coupling projection or the part containing the retaining pins could be rotated when disengaging, in order to deflect the retaining pins out of the recesses and then to be able to pull the coupling parts apart.
  • the cheaper and optically cheaper solution is that the coupling opening (s) containing the retaining pins are arranged on the coupling part and the coupling projection on the end face of the rods.
  • Embodiments of the invention and in particular the coupling and thereby both the arrangement of the clamping or screw sleeve as well as that of the holding brackets and also the resilient and deflectable mounting of the holding rods are the subject of claims 8 to 22.
  • Claim 23 relates to a solution in which the coupling projections are provided on the surface of the coupling part and the coupling openings on the end faces of the rods, but the design of the coupling opening and the coupling projections corresponds to those of the reverse arrangement and thus the type of assembly and disassembly remains the same.
  • Claim 24 contains alternatives to the screw or threaded sleeve.

  • an area 9 is provided on the coupling projection 5, which, when the coupling projection 5 is rotated relative, i.e. either an actual rotation of the coupling projection 5 or of the part having the coupling opening 4, radially extends the retaining pin 6 to the outer dimension of the Coupling projection 5 deflects, because this area 9 has the outer dimension of the coupling projection 5.
  • a threaded portion 10 is provided, on which one in the longitudinal direction of the Rod 2 and the coupling projection 5 is arranged by screwing adjustable threaded sleeve 11, but which is not used to produce a screw connection as a coupling, but rather in the coupling position, that is, when the coupling projection 5 is connected within the coupling opening 4 with the retaining pin 6, against that of the coupling connection adjacent surface area in the Sensed screwed and countered is that the coupling projection 5 and its recess 8 is braced against the retaining pin 6 against the direction of insertion.

  • the coupling projection 5 has at its front end in the insertion direction as the already mentioned inclined surface 7 a rounding or tapering or according to FIG. 4 a combination of both, which can be inserted between the two retaining pins 6 of each coupling opening 5.
  • two mutually opposite, radially recessed recesses 8 are provided on the coupling projection 5 for snapping in the two retaining pins 6 and in the circumferential direction between the two recesses 8 in each case regions 9, the radial extent of which is the lateral adjustability and adjustment of the retaining pins 6 and the greatest radial extent of the coupling projection 5 in the area of its insertion end.
  • This symmetrical arrangement of the holding pins 6 and the matching recesses 8 on a coupling projection can be seen, for example, in FIG. 3.
  • the dimensional relationships and diameter relationships of the areas 9 in the circumferential direction next to the recesses 8 can be seen, for example, in FIG.
  • the axial dimension of the lateral recesses 8 is gem. 4 greater than the thickness of the holding pins 5 and the adjustment path of the clamping threaded sleeves 11 corresponds at least to this difference in the dimension of the recess 8 compared to that of the holding pin 6 or is expediently somewhat larger in order to achieve a very secure bracing. Since the coupling openings 4 are deeper than the length of the coupling protrusions 5, these can also be inserted deeper into the coupling openings 4 in accordance with the larger dimension of the recess 8, which is helpful if, after coupling one end of a rod 2, the opposite End to be inserted into a coupling part 12 already held on rods 2.

  • the transition 13 to the recess base 8b is rounded approximately with the radius of curvature which corresponds to the radius of the cross section of the retaining pin 6, so that it fits well into this undercut and rounding of the transition 13.
  • Fig. 4 illustrates that thereby the recess 8 engages over the holding pin 6 in the use position hook-like, so that even at peak loads an unwanted deflection of the holding pin 6 is avoided.
  • an additional coupling part 12 cooperating with the rods 6 is provided, which in the exemplary embodiments according to FIGS. 1 to 15 is provided with an approximately spherical outer contour, while in the exemplary embodiment according to FIGS. 16 to 19 a coupling part 12 with an annular contour is provided.
