ABSTRACT:

The present invention relates to a track section for use in an electric toy racing car track system.
BACKGROUND OF THE INVENTION
In a conventional construction, an electric toy racing car track system is formed by a loop of track sections which are connected end-to-end together to form a pair of coextending lanes for respective toy cars to race with each other. Each lane is provided with a central groove for guiding a respective toy car by its bottom guide pin and a pair of conductive rails on opposite sides of the guiding groove for supplying electrical power to the toy car via respective brush contacts on the bottom of the car. The track sections have, invariably, a flat upper surface for the toy cars to run along in a manner which is smooth but monotonous.
The subject invention seeks to provide a track section for a toy racing car track system, which adds variation and fun to the game.
SUMMARY OF THE INVENTION
According to the invention, there is provided a track section for use in a toy racing car track system formed by a loop of track sections connected end-to-end together to form at least one lane for an electric toy car to run along and including a groove for guiding the movement of and a pair of conductive rails on opposite sides of the groove for supplying electrical power to the toy car, which track section comprises a body having a substantially flat upper surface formed with formations on at least one outer side of the rails for removably positioning respective obstacles for riding over by the wheels of the toy car.
Preferably, the formations are formed on opposite outer sides of the rails.
More preferably, the formations on each side of the rails are out of lateral alignment with the formations on the opposite side of the rails.
Further more preferably, the formations on each side of the rails are regularly spaced to form a row and are staggered with the formations of the row on the opposite side of the rails.
It is preferred that the formations are in the form of recesses for receiving bottom parts of the respective obstacles.
More preferably, the stone pieces are capable of providing a smooth transit for the wheels of the toy car to ride over them from the track section surface.
Further more preferably, the obstacles have a leading surface which is positioned or self-positioning to take the wheels of the toy car, thereby providing the smooth transit.
In a first preferred embodiment, the leading surface of at least one of the obstacles is pivotable to provide the smooth transit.
More preferably, the at least one obstacle has a body presenting the leading surface and including a pair of hinge pins on opposite sides for engaging with opposite sides of the respective recess.
In a second preferred embodiment, the leading surface of at least one of the obstacles is inclined or curved from the track section surface to provide the smooth transit.
More preferably, the at least one obstacle is fixed and has a body presenting the leading surface and including a bottom protrusion for press fitting into the respective recess.
The invention also provides a toy car racing track system including the aforesaid track section.
