Driving circuit for toy cars

Abstract

A playing field for cars guided by hand. The playing field consists of a plurality of rectangular plates ( 1 ) on which drive tracks ( 2 ) recessed like grooves are delimited by areal sections ( 3 ) not intended for driving and in which the plates are designed for mating engagement at their sides for joining the individual plates ( 1 ) together to form a larger travel course. The plates ( 1 ) can also be arranged one over the top of another plant by means of spacing holders ( 7 ). Insertion holes ( 6 ) for additional toys are provided on the plate ( 1 ).

         4 . The playing field according to    claim 1    wherein the plates consist of solid wood, plywood or chip wood and the drive tracks are produced by removal of material.  
     
     
         5 . The playing field according to    claim 2    wherein the plates consist of solid wood, plywood or chip wood and the drive tracks are produced by removal of material.  
     
     
         6 . The playing field according to    claim 1    wherein the plates consist of plastic and the drive tracks are produced by casting or stamping technology.  
     
     
         7 . The playing field according to    claim 2    wherein the plates consist of plastic and the drive tracks are produced by casting or stamping technology.  
     
     
         8 . The playing field according to    claim 1    wherein the plates consist of wood or of plastic and are built up in two layers consisting of a base plate and a plurality of areal plate sections attached to it.  
     
     
         9 . The playing field according to    claim 2    wherein the plates consist of wood or of plastic and are built up in two layers consisting of a base plate and a plurality of areal plate sections attached to it.  
     
     
         10 . The playing field according to    claim 1   , further comprising connection means are provided on the sides of the plates to provide for mating engagement of two adjacent plates.  
     
     
         11 . The playing field according to    claim 10   , wherein the connection means formed on the sides of the plates in a one-piece manner are provided as an insertion connection with dovetailed projections and recesses.  
     
     
         12 . The playing field according to    claim 10   , wherein the connection means formed on the sides of the plates in a one-piece manner are designed as irregular insertion connections having the shape of the projections and recesses known from puzzle games.  
     
     
         13 . The playing field according to    claim 10   , wherein the connection means are designed as insertion connections having the shape of those known from wooden tracks.  
     
     
         14 . The playing field according to    claim 10   , wherein bores for fixing pins are provided in the joint edges of the plates.  
     
     
         15 . The playing field according to    claim 1   , wherein the areal sections comprise insertion holes for attachment of an accessory part selected from the groups consisting of barriers, trees, pedestrians, and houses.  
     
     
         16 . The playing field according to    claim 15   , further comprising a plurality of vertical supports with which the plates can be arranged and held over each other at an interval in two or more planes.  
     
     
         17 . The playing field according to    claim 15   , further comprising a ramp which can be placed or folded down as a transition between two levels of drive tracks, which ramp can be provided within a plate or on an outer edge of said plate.  
     
     
         18 . The playing field according to    claim 12   , further comprising the drive tracks, the connection means and the supports are arranged in such a manner that the plates can be joined together in a grid in which the edge lengths of the plates form the grid.  
     
     
         19 . The playing field according to    claim 18   , further comprising the drive tracks, the connection means and the supports are arranged in such a manner that the plates can also by joined to each other offset by half a grid.
