Provided are a versatile track block for creating a track that is capable of securing a more dynamic range of motion for toy mobile object, rather than merely a toy block moved around by hand, and a track plan in which the order of colors or patterns of blocks on the track is recorded as a program. Projecting parts 100, 100 and recessed parts 101, 101 capable of mating with the projecting parts 100 are provided clockwise around the four sides of a block 1. A step part 16 is formed on the upper face of the block 1, and a magnetic plate 2 is set into this step part 16. A track can be created using a plurality of blocks 1 of this sort. In addition, blocks 6 comprising curved magnetic plates 24 and the like can be used to create a three-dimensional track that can be traveled in three dimensions.

A clearance compensation device for a model car includes: a guide part which is provided on the bottom surface of the model car and has a guide rail formed along the vertical direction; a clearance compensation part which is provided to the guide part, has a bottom surface that is in contact with the upper surface of a panel having a runway formed therein, ascends and descends along the guide rail in response to the shape of the upper surface of the panel when the model car travels, and is configured to compensate for a clearance between the bottom surface of the model car and the upper surface of the panel; and a magnetic body which is provided to the clearance compensation part and provided at the lower side of the panel with the panel therebetween to be coupled with the lead member movable in the horizontal direction.

The utility model discloses a universal splicing track and a toy car, comprising a plurality of I-shaped track bodies which can be assembled end to end and a toy car mounted on the track bodies, wherein a first step surface of a base is overlapped with a second step surface of another base, an upper end of the track body is provided with a bar-shaped block, one end of the bar-shaped block is provided with a spherical body, and the other end is provided with a connecting groove matched with the spherical body; and both sides of the bar-shaped block are provided with racks, a power mechanism is provided with output gears meshing with the racks at the two sides of the bar-shaped block, and one end of the output gear is provided with a guide wheel for clamping the bar-shaped block.

A vehicle configured to move through a network of interconnected tubes includes a body, a motor, a motorized wheel, a biasing assembly, and a first element. The motorized wheel directly engages an inner surface of the tubes. The biasing assembly causes the motorized wheel to maintain continuous contact with the inner surface of the tubes during operation. A waist of the vehicle is constrained by an inner diameter (D) of the curved tube, a radius of curvature (R) of the curved tube, and a length (L) of the wheelbase of the vehicle. The waist of the body is sized such that the vehicle can freely move within any of the tubes without getting stuck therein.

A track vehicle for traveling through a toy track system which includes pipe track sections connected together. The track vehicle includes a body having opposite ends and two sides; two diverting pulleys on the sides; a motor in the vehicle; a drive wheel, connected to the motor, at an end of the body; a battery; a control connected to the motor and the battery; two driving pulleys on the sides of the body, at an end of the body, wherein the driving pulleys and the drive wheel allow the track vehicle to stand and run on a plane; and a biasing wheel on top of the track vehicle for applying a force to an inner wall of a pipe track section, that is in contact with the drive wheel, to maintain the drive wheel in contact with the inner wall for driving the track vehicle along the pipe track section.

A toy track system for a track vehicle moving within the system includes a track section having pipe track section that are tightly connected to allow the track vehicle to pass through, and a non-track section formed by arrangement other than the track section. The track section includes an outlet end for the track vehicle to temporarily exit the track section and enter into the non-track section, and an inlet end for the track vehicle to return to the track section from the non-track section. A guiding device is provided at the inlet end for guiding the track vehicle to enter a pipe opening of the inlet end from the non-track section. The guiding device includes an end opening that is wider than the pipe opening. The track section further includes connecting devices having two connecting ports for detachably connecting the pipe track sections.
