Definitions

  • the invention refers to a building block game consisting of building blocks for assembly with each other and in turn to rotating elements, for example wheels, wheel rims and/or gears to be mounted on shafts or axles.
  • the blocks may be secured fixedly together by pegs, preferably of square cross section and fitted into corresponding holes, and some blocks have internal coaxial bores extending transversely of the peg holes for receiving correspondingly dimensioned coaxial shafts or axles.
  • the invention is based on the principle of creating a building-block game of the above general type but wherein it is possible to selectively establish non-rotating and rotating connections between either shafts and rotating elements or between shafts and building blocks.
  • the non- 3,6132% Patented Get. 19, 1971 rotating and/or rotating connection is provided within the rotating element and/or building block and is thus to be incorporated directly into assembly of the buildingblock game.
  • the invention preferably accomplishes this by providing at least one peripheral recess extending essentially in the axial direction over the entire length of a shaft.
  • the invention further provides for non-rotating assembly of the building blocks and rotating elements to the shaft, connecting and hub elements of non-rotating external shape in relation to the peg receiving hole and/or the axial opening of the rotating elements and with at least one internal projection entering the recess or groove of the shaft; as well as providing for rotating assembly, corresponding rotating and hub element without internal projections and/or essentially cylindrical external surfaces.
  • the rotating or non-rotating connection between a shaft and a building block and/or a rotating element is disposed within the building block and/or rotating element, so that the rotating and non-rotating connections can be assembled directly into a design model without affecting the assembly system of other building elements utilized in the design model.
  • the rotating and/ or non-rotating connections utilizing shafts can be made in many ways between only building blocks, between only rotating elements, and also between building blocks and rotating elements.
  • each shaft can possess at its periphery at least one flat segment extending over its entire length and the connecting and hub elements intended for non-rotating connection can have a projection fitting this flat segment in the bore receiving the shaft.
  • each shaft has at its periphery at least one, preferably two, diametrally opposite grooves extending axially over the entire shaft length, and the related connecting and hub elements intended for non-rotating connection have at least one, preferably two, diametrally opposite internal ribs in the bore receiving the shaft.
  • This arrangement of the axially grooved shaft and the connecting and hub elements with internal ribs provides a particularly reliable fixed connection between the shaft and the connecting and hub elements even when the latter are made of relatively weak plastic.
  • the axial grooves of the shafts may be relatively narrow to occupy only a relatively minor segment of the shaft periphery so that the shafts, in spite of these axial grooves, may rotate smoothly in the corresponding bores of building blocks and/ or other building elements.
  • each axial groove is widest at its outer lateral edges and is rounded off at the junction with the shaft periphery.
  • Each rib is preferably rounded at the junction with the surface of the internal bore of the connecting and hub elements and shaped to fit the groove. This rounded transition of the groove edges has the further advantage that, in rotating assemblies, the shafts have a low coefficient of friction in the respective bores.
  • the connecting and hub elements provided for non-rotating assembly are formed for at least a part of their length with a non-rotating external cross section corresponding to the pegged connections of the building blocks.
  • the connecting and hub elements provided for non-rotating assembly are thus directly adapted to associate with the peg assembly system of the building blocks.
  • a corresponding adaptation of the connecting and hub elements provided for rotating assembly to the peg assembly system of the building blocks can be accomplished if the connecting and hub elements for rotating assembly have cylindrical bores with no projecting ribs for at least a part of their length, the bore diameter being adapted to bushings inserted in the peg hole.
  • connecting elements such as bushings can correspond in their overall length to about half the depth of the peg receiving holes and about half the thickness of the related rotating elements, and can be provided over their entire length with the non rotating and/or rotating form of cross section adapted to the peg hole. It is of particular advantage when the sum of the overall length of a bushing-like connecting element and the height of a peg is slightly less than the depth of the peg receiving hole. This enables a bushing-like connecting element to be introduced into the peg hole of a building block and then covered by the peg of another inserted building block, so that the bushing-like connecting element behind the peg in the peg receiving hole retains sufficient axial play for rotation but nevertheless mintains satisfactory axial support of the shaft. It is of particular advantage here that it is possible in a very simple manner, to utilize a building block with its assembly peg as a gauge for axial adjustment of the bearing created by the bushing-like connecting elements.
  • the hub elements with a peg whose length is slightly greater than half the thickness of the rotating elements and also with a narrow collar adjoining the peg hole of the building blocks and/or the internal bore of the rotating elements in assembly.
  • This makes possible a rotary suspension of the rotating elements on the hub elements by inserting, on each side, a hub element into the axial bore of a rotating element. Due to the length of the inserted section of these hub elements, there then remains between the faces of the rotating element and the collars of the hub elements sufficient axial play for rotation but still providing satisfactory axial guidance of the rotating element.
  • the hub elements with their collar have the advantage that they limit not only the depth of insertion into a peg hole but also they close the respective peg hole and/or rcspective axial bore of a rotating element.
  • the axial bore of the rotating elements is formed with essentially the same cross section as the peg receiving holes of the building blocks.
  • the same connecting and hub elements may then fit both the peg receiving holes of the building blocks and also the axial bores of the rotating elements.
  • the shafts from a suitable metal, for example, brass, and the connecting and hub elements of shearresistanat plastic, for example of polyamide. It is of particular advantage if the bushing-like connecting elements and the hub elements for rotating assembly are formed to slide into fixed position on the shafts and formed for loose and/or rotary fit in the peg holes of the building blocks and/or the axial bore of the rotating elements, whereas the hub elements for non-rotating connection are designed for fixed position both on the shafts and also in the peg holes and/ or axial bores.
