  • Patent number: 5890948
    Abstract: A toy bridge comprising a stand and, supported thereby, a bridge road element having a roadway on each of two opposite flat sides. The stand is turnable and can optionally be placed on a base in a first or second position, in which the bridge road element is arranged at a first or a second distance from the base and its one or other flat side faces upwards. A supporting yoke is arranged at each end of the bridge to form a support for a ramp road element connected to the bridge road element. The supporting yoke is pivotable relative to the bridge road element by the force of gravity between a first and a second stop position, in which it forms a subjacent support for the ramp road element when the stand is in its first and its second position, respectively.
