Definitions

  • the invention relates to a roadway system for toy vehicles according to the preamble of patent claim 1.
  • lane systems are also known in which the individual lane sections or track sections are not only among themselves, but at the same time mechanically connected to a base plate or building board, which has a uniform, preferably square grid.
  • Such base plates form basic elements for toy building systems, in which the assembly of individual, numerous components is based on the fact that the components have primary and secondary coupling members, as a result of which the components can be mechanically connected to one another by being plugged on one another and can also be separated from one another again.
  • components are known in this regard that are box-shaped or plate-shaped and are provided on one main surface with coupling pins and on the opposite surface with mating coupling elements, for example correspondingly shaped wall projections.
  • the base plate is then also provided with primary coupling elements, for example coupling pins, with all coupling elements naturally being arranged in the same manner and at the same intervals in accordance with a construction module on which the relevant construction system is based.
  • the object of the present invention is to provide a roadway system of the type mentioned in the introduction, in which at least the two ends of each curved roadway section correspond to grid points of the square grid of the base area.
  • the carriageway system has the features specified in the characterizing part of patent claim 1 for fulfilling this task.
  • the design according to the invention of the straight and curved lane sections makes it possible for them to be exactly matched to a base plate provided with a square grid of coupling members without difficulty with this grid, so that a connection that can only be brought about by force is completely avoided.
  • the curved road sections are different, depending on whether it is a right-hand bend or a left-hand bend, and since the straight road sections can also differ in length by a factor of ⁇ 2, depending on whether these road sections are parallel or are used diagonally to the grid of the base area, it is advantageous to use a mechanical, ie formal, or to be provided with a visual coding. As a result, the assembly of several pieces of roadway to the roadway system is made possible automatically and without any consideration, which makes the use of the roadway system accessible even to inexperienced persons, in particular small children.
  • FIG. 1 shows a square grid 1 with a grid module M, the module M having the unit size, that is to say the side length of each square of the grid 1 has the unit value one.
  • Circular arcs 2 are drawn into this grid, the radii of which start from a centrom Z0 lying in the corner of a square.
  • three different angular ranges for circular arc pieces of 22.5 °, 30 ° and 45 ° are indicated in FIG. 1 by correspondingly inclined straight lines 3, which also start from the center Z0.
  • Symmetry points of the square grid 1 are corner points, center points or bisecting points of the squares of the grid.
  • these lane sections must be designed so that at least their two ends, defined by a center line of each lane section, geometrically coincide with a point of symmetry of one of the squares of grid 1. Since such a covering with arc-shaped road sections and a square 1 is to be shown below with reference to FIG. 1 how large the deviations from the desired geometric coverage are as a function of the size (radius and angular range) of the circular arc pieces.
  • FIG. 2 This figure relates to cases I to IV of FIG. 1, the case V being omitted on the one hand for reasons of clarity and on the other hand because it is based on an already considerable circular arc radius of 5.5 m.
  • FIG. 2 shows, on a larger scale, again the square grid 1 with the grid module M, which is referred to below as the roadway module. Furthermore, FIG. 2 contains the straight line 3 starting from the grid center Z0, which is inclined at 45 ° and therefore diagonally, and the circular arcs RI to RIV which are decisive for the four cases I to IV in FIG. 1.
  • the points of intersection of the straight line 3 with this circular arc are again denoted by rings, while the points of symmetry of the grid 1, with which reference points located at the ends of the carriageway sections are intended to cover, are shown with full points.
  • each piece of roadway 4 according to the invention consists of a circularly curved section 8 and a straight section 9, which is shown hatched.
  • the circular section 8 of each track section 4 is determined by the following definition of its center.
  • a tangent condition must be fulfilled by in the present case of a lane section extending over an angular range of 45 °, the tangent to the lane section or its center line in one end point of the lane section must be parallel or perpendicular to the grid 1 and in the other end point of the lane section in the diagonal direction of the grid 1, so that further lane sections fit get connected.
  • the geometrical location for the fulfillment of the above-mentioned tangent condition is the bisector of the two tangents placed in an end point 6 or 7 of the lane section 4. These tangents are designated T in FIG. 2 for case I. In FIG. 2, the respective bisector WI to WIV of these tangents are also shown for all cases I to IV.
  • each lane section 4 results from the intersection of the relevant bisector with one of the radii delimiting the angular range of the lane section, that is to say with reference to FIG. 2, from the intersection of the respective bisector WI to WIV with the straight line 3 or horizontal radial line 3 ′.
  • each lane section consists of a curved and a straight section and therefore one end of the lane section is the end of its curved section, which consequently coincides with one of the limiting radii mentioned.
  • intersection points which define the centers of the arcuate sections 8 of the lane sections 4, are denoted by ZI to ZIV.
  • Decisive for these intersections is the fact that virtual intersections of the bisector WI to WIV with extensions of the straight line 3 and the radial line 3 'beyond the center Z0 are no solutions, since in any case the corrected radius from the specified center ZI to ZIV to End point 6 or 7 of the lane section 4 must be smaller than the uncorrected radius of the original circular arcs RI to RIV.
  • the bisector WI and WIII of the lane sections 4 of the cases I and III intersect the straight line 3 in the centers ZI and ZIII, while the bisector WII and WIV of the lane sections 4 of the cases II and IV intersect the radial line 3 'in the centers ZII and ZII, respectively. ZIV cut.
  • each arcuate section 8 of the lane sections 4 is also fixed, since each circularly curved section 8 extends over an angular range of 45 ° around its center ZI to ZIV.
  • each arcuate section 8 is supplemented at that end by a straight section 9, which is opposite to the other end coinciding with the radius containing the center in question.
  • the straight section 9 extends here to the other radius and has a length that is equal to the vertical distance of the center in question from this other radius.
  • Fig. 2 the resulting straight sections 9 of the road sections 4 for cases I to IV are shown hatched. From this it can be seen in particular that when the intersection of the relevant original arc RI ... RIV with the center ZO with the 45 ° straight line 3 comes to lie radially inward from the next point of symmetry of the grid 1, the straight section 9 is on the Side of the horizontal radial line 3 'is located, and vice versa. It can also be seen that the greater the deviation from the geometric coverage, the greater the length of the straight section 9. As explained below, this circumstance can be a criterion for the selection of a specific design of the lane section for a lane system.
  • FIG. 3 again shows the square grid 1 with the roadway module M corresponding to FIG. 2.
  • the curved lane section 4, which has the lane width 5, corresponds to that of case I in FIG. 2, which is explained here for example.
  • Z0 in turn denotes the center of the original circular arc RI of FIG. 2, not shown in FIG. 3.
  • the track section 4 has a first end point 6 with respect to a center line 10, which is at a distance of 3.5 M from the center Z0 on the radial line 3 ', that is to say in a point of symmetry of the grid 1.
  • the other end point 7 of the track section 4 lies in the center of a square of the grid 1 on the diagonal straight line 3. Furthermore, in FIG the two tangents T to the center line 10 in the end points 6 and 7 are shown. Its bisector WI intersects, as already explained with reference to FIG. 2, the straight line 3 at point ZI, which forms the center of the arcuate section 8 of the road section 4.
  • x also denotes the distances of the end point 7 from the center ZI measured in the directions of the grid 1.
  • the size of the roadway module M can be determined by the component system for toy building models in which a roadway system of the present type is to be built.
  • Such a roadway module is in a component system, for example, by the modular assignment of streets, groups of houses and the like on the Base area determined. It follows that for curved track sections 4 according to FIG.
  • the corrected radius y of the arcuate section 8, based on its center line 10 has a length of 218.5 mm, and that the displacements z and z 'of the center ZI of the arcuate section 8 or the length of the straight section 9 have a value of 5.5 mm.
  • values y and z or z ′ can also be determined for other cases, in particular cases II to IV according to FIG. 2.
  • This dimensionless ratio is a useful indicator for the section of road in question by indicating what percentage the straight section has with respect to the arcuate section.
  • This ratio number is therefore a measure of the relative deviation of an impossible geometrical coverage of the intersection of the arc in question with the 45 ° straight line and the assigned point of symmetry of the lane grid for the reference point at one end of the lane section, cf. Fig. 1. With a complete, but not possible geometric coverage, this ratio would be zero.
  • curved road sections according to Case I offer the most advantages.
  • the following description of embodiments of curved lane sections is therefore restricted to lane sections of the configuration according to Case I in FIG. 2, but without the present invention being restricted to this case.
  • Fig. 4 are in the lane grid 1 with the lane module M all possible curved lane pieces in this grid according to Case I and all straight lane pieces, in each case positions rotated by 45 °.
  • the curved road sections shown do not require any further explanation following the preceding description.
  • the straight lane sections shown have a length which, according to the invention, is in a fixed relationship to the lane module M of the lane grid 1.
  • all straight lane sections that are parallel to the lane grid 1 have a length of 3 M, and those straight lane sections that lie diagonally to the lane grid 1 have a length of 2 ⁇ 2. M.
  • other factors k can also be used for the lengths of the straight lane sections, insofar as this fulfills the condition that reference points at the ends of the lane sections come to coincide with points of symmetry of the lane grid 1.
  • the factor k can accordingly have the values 0.5-1-1.5-2-2.5, etc., so that the reference point previously defined for the curved road sections in the layers according to FIG. 4 is always in a point bisecting point, a center point or a corner point of a square of the lane grid 1 comes to lie.
  • coding elements 11, 13 and 12, 14 are indicated schematically at the ends of all straight and curved road sections.
  • the purpose of these coding elements is to ensure that a specific lane section of the type according to the invention can only be connected to a lane section of this type if, owing to the design of the further lane section, the correspondence of the defined reference point at the end of the first-mentioned lane section with a point of symmetry of the lane grid 1 is continued by the further lane section.
  • the curved lane sections can be divided into two groups of different designs, namely right and left lane sections, and that this also applies to straight lane sections, namely whether they are intended for grid-parallel or grid-diagonal laying.
  • a carriageway installation of the type according to the invention insofar as it is built up in a single plane, will basically comprise four different groups of carriageway sections, half of which relate to the curved and one straight carriageway sections.
  • the coding elements consist of projections 11, 12 arranged at each end of the road sections and depressions 13, 14 corresponding to these projections. Any two road sections of Fig. 4 can therefore only be connected to one another if the desired one Composing the projecting coding element 11, 12 of the one lane section opposite the recessed coding element 13, 14 of the other lane section in order to bring these mutually corresponding coding elements into mutual engagement. If this is not possible because a protruding coding element 11, 12 of one lane section is opposite a likewise protruding coding element 11, 12 of the other lane section, the user merely has to select the other of the two different and differently encoded lane sections of the same group of curved or straight lane sections and add. So the structure is a roadway system according to the invention possible without any training, knowledge or experience.
