As an embodiment of the present disclosure, a connection member of an assembly toy includes: a body formed as a solid figure similar to a rectangular parallelepiped, the body including a circular opening in a center of an upper surface and openings of oval shapes in a left side surface and a right side surface; a leg protruding out of the body through the openings of the oval shapes in the left and right side surfaces of the body; and foot models respectively connected to left and right end portions of the leg.

Provided is a wheel-shaped self-assembly connection member including a wheel of a circular shape, and having an internal space that is partitioned into a plurality of fan-like shapes; a protruding circular connector of a cylindrical shape protruding from a center axis of the wheel in a direction to perform as a driving axis, the cylindrical shape having a female void performing as a connector; and circular connectors located in the fan-like shapes in directions of north, south, east, and west in the wheel, each of the circular connectors having a center void performing as a connector.

Provided is an assembly toy including an internal cylindrical body, an external cylindrical body surrounding the internal cylindrical body and having a spiral recess in an internal side surface thereof, and an insertion member inserted to a void in the internal cylindrical body to be engaged with and coupled to the internal cylindrical body. When the insertion member is rotated, the internal cylindrical body moves along the spiral recess in the internal side surface of the external cylindrical body.

A 3-dimensional high-speed track car toy comprises a track body and a toy car. Straight tracks, curved tracks, centripetal tracks and centrifugal tracks are assembled to form a 3-dimensional closed track. The track body stands on the ground fixedly through support rods and support seats. The track body is paved with a track along which the toy car runs. Components of the track body have fastener-containing groove structures to fix an iron axis onto the track. The toy car is placed on the track body. The track is equipped with an iron axis. The bottom of the toy car is equipped with magnets. Thereby, a sufficient attractive force is generated to overcome gravity of the toy car. Therefore, the toy car can run on the track disposed on a ceiling or a vertical wall. Thus, the user can enjoy more amusement from playing the present invention.

Provided is a toy block. The toy block includes a first rotator formed on a body, a second rotator on an outer portion of the first rotator, and a gear portion switching a rotation movement of the first rotator to a rotating movement in an opposite direction to transfer the rotating movement to the second rotator.

A track tension device and a track moving device are provided. The track tension device includes an upper transmission belt, a lower transmission belt, an upper tension portion, a lower compression portion and a resilient support portion. The track moving device includes the track tension device.

A portable, lightweight racer vehicle. The racer includes a body, a motor and a battery powering the motor, a motorized wheel, a first wheel, and a spring-loaded wheel to cause the motorized wheel to maintain contact with a surface upon which the motorized wheel rotates. The first wheel is larger than the motorized wheel and the spring-loaded wheel. A tube section includes a first half section having a pair of interlocking fingers and a pair of notches; and a second half section having a pair of interlocking fingers and a pair of notches. The two halves are removably snap-fit or press-fit together by joining the pair of interlocking fingers of the first half section with the pair of notches of the second half section while simultaneously joining the pair of interlocking fingers of the second half section with the pair of notches of the first half section. A splitter pipe includes a body having an input port and at least two output ports, and a remotely controlled valve between the input port and the at least two output ports. The splitter pipe is non-opaque, and an inner diameter of the input port does not exceed 2 inches.

This double-sided toy car is capable of vertical turning within a sealed track. The double-sided toy car includes a car body, a front wheel, and a rear wheel. The rear wheel includes a pair of upper driving wheels and a pair of lower driving wheels. A maximum distance between an upper end and a lower end of the front wheel is less than or equal to a maximum distance between the upper and lower driving wheels after the rear wheel is maximally elastically contracted. The maximum distance is less than or equal to a height of the sealed track, therefore ensuring that the double-sided car can smoothly pass through a vertical turning segment. However, the maximum distance between the upper and lower driving wheels before the rear wheel is elastically contracted is greater than the height of the sealed track.
