SLOT CAR WITH SPIN-OUT RECOVERY SYSTEM
A slot car and track system that can simulate a slot car spin-out delay while avoiding the need to manually re-align the slot car on the track. The spin-out delay is created using a guide that extends from the slot car into the slot car track. The guide triggers electronics when the slot car chassis achieves a turning angle near that necessary to cause a spin-out. Once triggered, the electronics cease power to the slot car motor for a specified period of time. Once the time has elapsed, power is once again restored to the slot car motor. Because power to the slot car motor is ceased before the slot car spins-out or becomes detached from the track, manual re-alignment of the slot car on the track is unnecessary.

BACKGROUNDSlot car racing is a hobby using powered miniature automobiles guided by grooves or slots on a track. Competitive slot car racing occurs in a variety of settings, including casual congregations at home to advanced competitions where contestants compete with slot cars built for maximum performance. These advanced competitions resemble other competitive motor sports and include series of races culminating in a national championship.
Slot car racing includes a roadway having a network of continuous slotted tracks around which one or more slot cars race. The roadways are generally laid out in such a manner that at least two tracks are directly adjacent to one another to permit competition between several slot cars. Continuous electrical contact strips adjacent to each slotted track provided continuous electrical power to the slot cars and their electric drive motor.
An inherent problem with slot car racing is the manner in which the tracks are arranged to simulate actual road racing conditions. The tracks are laid out with numerous sharp curves that require a high degree of skill to negotiate at high speed. Since many slot cars are highly powered, it is common for a slot car entering a curve at high speed to spin-out of control. When a slot car spins out of control, it may disengage from the track, or in cases where only the rear end of the car swings out, it may lose contact with the electrical contact strips. In either case, the slot car loses power and the racing is temporarily interrupted while the participant manually realigns the slot car on the track.
Several attempts have been made to avoid or minimize the slot car racing interruptions caused by spin-outs. One attempt to address these problems is to reduce the available power to the slot car to more closely match its weight. However, in some instances, this has resulted in the slot car swinging broadside upon the application of additional power when entering a curve. Another approach to prevent loss of slot car control was to provide a differential front wheel drive slot car. Still, another approach was to automatically realign the slot car after a spin-out or other loss of power. However, these attempts result in overly complicated slot car and track arrangements.
For the foregoing reasons, there is a need for a slot car and track that can avoid racing interruption by managing spin-out and therefore provide for continuous slot car racing. The solution is found in the present invention that comprises a feature to lock the slot car into the track and a feature to simulate vehicle spin-out by causing the slot car to momentarily lose power when the slot car reaches its limit of traction.
SUMMARYThe present invention is directed to a system that satisfies this need for a slot car and track that can simulate a slot car spin-out delay while avoiding the need to manually re-align the slot car on the track. The system includes a slot car with chassis comprising a radius slot and guide that triggers a set of electronics to temporarily cease power to the slot car's motor. The radius slot and guide further prevents the car from separating from the track and limits lateral movement of the slot car so that manual re-alignment of the slot car on the track is no longer necessary.
In traditional slot car racing, the slot car is guided along a track having a slot while the operator adjusts power to the slot car's electric motor. The power is delivered to the motor through electrical contact strips in the track, alongside the track's slot. If the user applies too much power to the slot car when entering a turn in the track a “spin-out” can occur. A “spin-out” is when the rear of the slot car slides laterally to such a degree that the car is no longer in contact with the electrical contact strips in the track. In some instances, a “spin-out” causes the slot car to become completely disengaged from the track. In either instance, the slot car must be manually replaced on the track in a forward direction in order to resume racing.
The present invention, a slot car with chassis and front guide similar to those typically used for slot car racing, further comprises a secondary middle guide that is capable of lateral movement within chassis. Instead of separating from the track or shifting to such a degree as to need manual re-alignment on the track, the slot car will instead remain attached to the track and lose power for a set period of time, thus simulating the time lost during a spin-out.

The distal end of the front guide 110 (shaft) comprises a larger cross section than the shaft so that the slot car 110 can remain attached in the track 200 bottom slot 204. In a preferred embodiment, the front guide 110 is an inverse T-shape, with the distal end being rectangular in shape. The distal end further comprises electrical contacts 116 to transfer electricity from the electrical contact strip 206 to the slot car 100 electronics 104. Two electrical contacts 116 are affixed to the distal end of the front guide 110. Comprised of an electrically conductive material, such as metal, the contacts remain in contact with the electrical contact strip 206 within the track bottom slot 204. In a preferred embodiment, the electrical contact 116 lead wires enter the slot car chassis 102 through the front guide 110, where they attach to the slot car electronics 104 as illustrated in
