The present disclosure relates to a toy vehicle and a toy track system.
Many toy track systems are open top track systems where toy vehicles, especially those travelling at relatively high speed can easily fall out or shoot off.
It is known to provide a closed track system. U.S. Pat. No. 9,731,212 (Cheung). That system is not flexible in use and is restrictive of vehicle traffic patterns and speeds.
The disclosure overcomes the problems of existing toy vehicle and toy track systems.
There is provided a toy vehicle and track system within which one or more toy vehicles move along. The disclosure relates to a toy tube track set.
A plurality of toy vehicles can race together in this track set. The track system comprises of different types of plastic tubes, toy vehicles and a transmitter. The toy tube can be in different shapes such as straight type, curved type, X-type, Y-type and open-type. In the disclosure, most of the tubes can be assembled by end users by simply snapping two symmetrical half tubes together.
The tubes are inter-engageable with each other to be freely rotatable relative to each other, the rotatability being about a central axis running through each tube end.
A vehicle runs through the tubes without being pressed against the inner sidewall of the tubes. The vehicle has a drive wheel resiliently urged towards an inner surface of the tube for moving frictionally along the inner surface.
A toy kit comprising the toy vehicle and the toy track system.
The disclosure is described, by way of example only, with reference to the accompanying drawings, in which:
The disclosure is described in further detail with reference to the drawings.

The principal and auxiliary guides include rotatable elements.
There is a transceiver system between a vehicle and a transmitter whereby the vehicle is controllable by signals from the transmitter.
The first and second tubes are provided at one end of the first and second tube sections respectively at which they are connectable endwise.
The first tube is insertable into the second tube for inter-engagement of the first and second tubes to connect axially between the first and second tube sections.
The coupled first and second tubes inter-engage towards their ends to connect axially between the first and second tubes. They interlock and can be relatively freely rotatable relative to each other.
A toy vehicle moves in and along a toy track system having a longitudinal central axis. The vehicle includes a body having opposite first and second end and opposite first and second sides. There is a driving wheel provided at the first end on the first side of the vehicle body for frictional engagement with an inner surface of track system to move the vehicle body.
A motor in the vehicle body rotates the driving wheel. There are gears in the vehicle body for transmitting a drive from the motor to the driving wheel for rotating the driving wheel.
The vehicle is free to move in the tube. A driven geared wheel in the vehicle is urged by the internal suspension to engage the tube and the driving wheel propels the vehicle in the tube. The driving wheel is mounted to be relative movable towards and away from the vehicle body and be rotatable relative to the vehicle body.
The toy vehicle includes guides are disposed on the top end and a bottom end and first and second sides of the vehicle, and are fixedly mounted to the vehicle body to be fixedly spaced relatively to the body. The principal guides are located on a first plane which extends-removed from and relative to a second plane on which the driving wheel is located. The guides include freely rotatable elements.

Generally, the tubes are in a plane of symmetry design so that they can be assembled by snapping the hooks 9 of a first half tube to the latches 8 of a second half tube at one side and snapping the latches 8 of a first half tube to the hooks 9 of a second half tube at the other side. Alternatively, all hooks and latches are put on first half tube and second half tube respectively.
With this tube design, it is possible to stack up all half tubes with same shape for close packing.
The first end of the tube includes a flexible snap joint 6 while the other end of the tube includes a notched ring segment 7.
To connect two tubes together to form part of the track set, the snap joint of first tube is plugged into the notched ring segment of second tube.
After snapping the first tube to second tube, both tubes can be free to rotate along their longitudinal axis.
By cascading many different tubes with this method and rotating the tubes at any desired angular position, an open or closed loop track set can be constructed.
While racing, users should put their vehicles with different ID inside the track set through the inlet of open-type tube. They can drive their vehicles by corresponding transmitters and change their lanes inside X-type or Y-type tube.
A set of plastic tube which can be used to construct at least one complete open or closed loop in 2D or 3D pattern.
The vehicle 100 comprises:
The transmitter 200 comprises:
Different vehicles and transmitters have their ID.
The IR signal from transmitter embedded at least one of the following information:
Alternatively, the transmitter can have Forward, Backward, Left and Right buttons. In this way, it supports full function control and it is possible to play with the car off the track set.
Alternatively, the whole smart driving system can work properly without a transmitter.
The control method of transmitter is not limited to Infra-red. It can be radio controlled, Bluetooth or WiFi controlled.
Upon receipt the IR signal from transmitter, if its ID is match, the vehicle will move or stop according to the signal command.
The vehicle is equipped with at least 4 guide rotatable elements to ensure it can run smoothly inside the tube.
The vehicle is driven inside the tube in an extreme case, for instance, vertically upward or downward without slip. Firstly, there is the rear driving wheel which associates with the suspension system to provide sufficient friction between the rear driving wheel and the tube surface at different angular positions. This occurs even though the tube is not a perfect cylinder or a cylinder. Secondly, when the motor is in a high speed turning mode, the driving wheel provides high torque and hence works to overcome the gravitational force of the vehicle itself.
The vehicle can be equipped with over-current detection design. When a player holds at least one of the driving rotatable elements or wheels and leads to a motor stall, the MCU can measure this unexpected high current and stop the motor power automatically.
The vehicle can be recharged by a USB cable and external charger or through transmitter
Alternatively, the car can be driven by plurality or number of button cells, alkaline or heavy-duty batteries.
The disclosure has been set out by way of example only. For instance, one or more of the driving wheel, front wheel and one or more of the rotatable guiding elements can be sized larger or smaller radially and/or laterally relative to the vehicle body. Various other modifications of and/or alterations to the described embodiment may be made without departing from the scope of the disclosure as set out in the following claims.
