Definitions

  • the invention relates to a prismatic toy module made of plastic, which has an undercut connecting pin made of a different material than the module on at least one end face and undercut grooves on the other surfaces intended for engagement with the connecting pin of adjacent modules, the connecting pin in the module is used with an extension, are arranged on the longitudinal ribs to prevent rotation.
  • connection between the connecting pin and the undercut grooves requires maximum dimensional stability, on the one hand to keep the frictional forces at a value that can still be easily overcome by a child and on the other hand to achieve a connection quality that is also effective in the longitudinal direction of the groove.
  • Higher dimensional stability is controllable with a solid building block, but in addition to the higher proportion of material and the longer injection times, it has the disadvantage that due to the rigidity, the connection pin is difficult to attach to the insertion area of the grooves.
  • a tubular design of the block according to DE-PS 1 290 696 could possibly solve this problem because of the higher elasticity of the profile, but this elasticity exists over the entire length of the block, so that the pull-out strength of an inserted in a groove by springing away the corner areas Connecting pin is reduced to a dimension that is no longer portable.
  • the dimensional accuracy of the grooves can no longer be controlled in such a way that all four grooves of the module have the same sliding conditions.Furthermore, in the known equipment specification of the module with an undercut connecting pin, a stiffening of the hollow structure occurs precisely in the insertion area of the grooves stone profile, so that the difficulties in inserting the connecting pin still exist.
  • the invention has for its object to improve a prismatic plastic toy block of the type mentioned in the preamble such that with the same connection quality as a solid block on the one hand the insertion of the connecting pin is improved in the undercut groove and on the other hand, a saving effect is achieved.
  • the module at least from one end face, is largely hollow over a part of its length corresponding to the outer contour, the width of the narrowing of the cavity resulting between two mutually perpendicular grooves being adapted to the thickness of the longitudinal ribs.
  • the depth of the cavity can correspond to the length of the extension. This results in a depth stop for pressing the extension having the connecting pin with the module.
  • the hollowing out of the four corner regions resulting between the longitudinal grooves can extend over the entire length of the module.
  • a steel core can be pressed into the extension in a manner known per se, which is anchored with a part projecting beyond the extension in a core bore of the component. This measure serves to increase the mounting of the connecting pin in the module.
  • the prismatic module 1 shown in Figures 1 and 2 is provided with longitudinal grooves 2 and on one end face with a spigot 3.
  • the connecting pin 3 is equipped with an extension 4 which has cross-shaped longitudinal ribs 5.
  • These ribs 5 have, on the side facing the connecting pin, bearing surfaces 6 which, after the extension 4 has been pressed into the receptacle 8 formed by the wall J of the longitudinal grooves 2, protrude slightly above the level of the end face of the component and thus form a counter bearing.
  • the longitudinal ribs 5 are received by the resulting between two grooves 2 cavity narrowing 9, the inside width corresponds to the thickness of these ribs 5. This results in a rotation lock for the connecting pin 3.
  • the depth of the cavity 10 corresponding to the outer contour of the block 1 is equal to the height of the extension 4, so that there is a depth limitation when the extension is pressed into the end face of the block.
  • a steel core 11 is pressed into a bore of the extension 4, which projects beyond the extension 4 with a part 11 a. This roughened section 11 a of the steel core is anchored in a corresponding bore 12 of the block 1.
  • the cavity 10 extending from one end face and extending over part of the length of the building block results in an elasticity in the insertion area of the longitudinal groove 2, which facilitates the attachment of a connecting pin 3 by reducing the friction.
  • the high rigidity is then again desired in order to prevent the connecting pins from being easily clipped out of the longitudinal grooves.
  • This rigidity is achieved by connecting the groove walls by correspondingly fully spraying out the component core 13, while the four corner regions 14 that result between the grooves 2 are hollowed out over the entire length of the component.
