Definitions

  • the invention relates to a node part for connecting adjacent components, preferably for model construction, which is provided with recesses for fastening elements of a surface or space lattice work.
  • Such node parts can e.g. find use in scaffolding or model construction and generally have approximately the shape of a ball, into which radial recesses for screwing in or other fastening of scaffolding rods or threaded pins or the like arranged on any components are incorporated.
  • Such node parts are shown e.g. DE-C 876 977, DE-C 901 955, or DE-A 2 905 638.
  • node parts are usually solid and therefore very heavy, there is also the further difficulty that such node parts generally require mechanical processing, which increases or increases their production costs and thus the price.
  • the object of the present invention is therefore to create a node part which on the one hand has only a low weight but on the other hand is made of a material having sufficient strength and rigidity, e.g. Aluminum or plastic, can be manufactured inexpensively.
  • this object is achieved in the case of a node part mentioned at the outset by means of two identical, cylindrical or prismatic structures, each of which essentially has a plurality as recesses for fastening Lichen radially directed bores or channels and a recess extending from the central axis of the respective structure to the edge of the same, the width of which is so equal to the height of the structure that these two structures are crisscrossed together a node part with four offset by 90 0 to each other, radially Form outward-projecting ribs.
  • these two structures can not only be essentially rotationally symmetrical, but can also be completely identical, they can easily be made from aluminum by die casting or from plastic by injection molding. The only important thing here is that these two structures, which together form the junction part, have sufficient rigidity and strength to be able to withstand the mechanical stresses that occur.
  • these structures have a hexagonal or octagonal cross section, the adjacent bores or channels then enclosing an angle of 60 ° or 45 °.
  • the loads occurring here are only relatively small, which makes it possible to manufacture the structures according to the invention each from an elastic material, in particular from plastic.
  • this elastic material also allows that at a distance from the respective outside of the relevant node part in each of the radially directed bores, an undercut forming annular groove is incorporated, the bottom of which is expediently designed such that the annular groove has a shape a cavity having a spherical section.
  • each of the two structures is composed of two identical halves of the structure, which lie snugly against each other and glued together in the central plane determined by the longitudinal axes of the radial bores or channels , welded or connected in some other way, the radial bores or channels located in a structure being formed in each case by mutually opposing longitudinal cross-sections which are preferably semicircular in cross-section and located on the opposite sides of the two halves of the structure.
  • This division of a structure into two structure halves has the particular advantage that the tool required for the injection molding of these structure halves can now be made much easier, in particular if the radial bores or channels of both structure halves in the structure in question have the shape of open channels, which form the radially directed bores or channels after the two halves of the structure have been joined together.
  • cylindrical recesses are formed in the abutting sides of the two structural halves, the longitudinal axes of which are relative to the longitudinal axes of the radial bores or channels are directed vertically and fully engage in the pegs or the like formed on the opposite side of the other half of the structure.
  • protruding ribs, feet, pins or the like are formed on at least one of the two opposite sides of the two halves of the structure, whereby the cross section of contact between the two halves of the structure is considerably reduced and thus the effect of ultrasound is significantly increased .
  • a node part made of plastic By means of such a node part made of plastic, completely arbitrarily designed components and rods can be connected to one another. These components and rods each have a spigot engaging in a radial bore located in the relevant node part, in which case at least this spigot is also made of an elastic material, e.g. made of plastic. Furthermore, a reinforcement projecting in the radial direction and engaging in an annular groove located in the radial bore is expediently attached to the outer circumference of such a pin. This reinforcement is advantageously integrally formed on the pin end and spherical.
  • the node part 1 shows a node part designated by 1, which serves to connect elements designated by 2, here in the form of bars.
  • the node part 1 is composed of the two structures 3 and 4 shown in FIGS. 2 and 3, each of which has the shape of an octagonal prism.
  • each structure 3, 4 has a rectangular recess, designated 7, which extends from its outer edge 9 to its central axis 8. The width b of this recess 7 is equal to the height h of each of the two structures 3 and 4.
  • each of the two structures 3, 4 again consists of two halves of the structure designated by 13 and 14, with their mutually opposing inner surfaces pages 15 and 16 bear against each other and are glued or welded together, for example by ultrasonic welding.
  • FIG. 6 shows a view of one half of the structure 13, viewed in the direction of arrow A in FIG. 5.
  • these channels 17 each form a channel similar to the bore or channel 6 with the counter channels 18 located in the opposite inner side 16 of the other half 14 of the structure, the cross section of these channels 17, 18 is each semicircular.
  • These channels 17, 18 meet in the central axis 8 and each run out into an opening denoted by 19, which widens outwards like a cone.
  • an annular groove designated 20 is formed in each of the channels 17 and 18, which together with the channel 17 and 18, as shown, forms a hemispherical cavity 21 forms.
  • cylindrical recesses 22 are machined between these channels 17 and 18 in the inner side 15 of the body half 13, into which protrusions 23 of the same dimensions formed on the opposite inner side 16 of the other body half 14 project.
  • cylindrical recesses 24 are also machined in the inside 16 of the other half of the structure 14 and associated with pins 25 formed on the inside 15 of the half of the structure 13. These pins 23, 25 serve to connect and correctly position the two halves of the structure 13, 14.
  • the plastic halves 13 and 14 When assembling the node part 1 shown in Fig. 1, the plastic halves 13 and 14 are placed together with their inner sides 15 and 16, the cylindrical pins 23 and 25 engaging in the opposite cylindrical recesses 22 and 24 and so the Secure both halves of the structure 13 and 14 against rotation. Thereafter, the two halves 13, 14 of the structure are intensively glued, welded or otherwise connected, whereby the structures 3, 4 shown in FIGS. 2 and 3 are formed. These two structures 3 and 4 are then inserted into one another in the manner mentioned above in the direction of arrows 10 and 11 and, if appropriate, glued or otherwise connected, as a result of which the node part 1 is formed.
  • This hub part 1 serves to connect the BE 2 - recorded bars whose bar ends 27 each having in its axial extension a pin 28 to be inserted in the axial direction in one of the bores located in the hub part 1.
  • the pins 28 each end in spherical ends 29, the diameter D (FIG. 6) of which is greater than the diameter d of the bores or channels 6.
  • Holes 6 must therefore each dodge the elastic plastic material of the annular mouth region 30, to allow the passage of the spherical pin end 29.
  • the annular region 30 returns to its original shape and encloses the neck 31 of the pin 28, designated 31, such that the spherical pin end 29 no longer comes out of the bore 6 able to solve. But this ensures a secure fit of the pin end 29, the rod end 27 and thus the entire rod 2.
  • node part 1 described in detail above is made of plastic, it is very light and elastic, which opens up the special possibility of using it both in model construction and in toys of various kinds, but in particular in toy building sets.
