A toy vehicle includes a chassis, at least two wheels, and an actuating mechanism configured to couple the at least two wheels to the chassis and to move the at least two wheels between a retracted position and an extended position in which a width of each wheel of the at least two wheels is increased. The actuating mechanism includes a lever configured to be moved between a first position corresponding to the retracted position of the at least two wheels and a second position corresponding to the extended position of the at least two wheels. The actuating mechanism further may include an actuator configured to move the lever from the first position to the second position and from the second position to the first position.

Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

A propulsion system for a vehicle or toy vehicle is disclosed. The system comprises rotary drive means for driving the vehicle along ground, the rotary drive means operating in a plane and having a peripheral ground-engagement part. The system further comprises a rotor comprising one or more rotor blades rotatable about a rotor axis for producing thrust, wherein the rotary drive means and the rotor are positioned relative to each other so that during rotation of the rotor, the rotor blades pass through the plane of the rotary drive means, inside the peripheral ground-engagement part. In this way, the rotor blades are protected by the peripheral ground-engagement part.

The present invention provides a self-righting model vehicle.

A modular robot system includes N (N is an integer that is 2 or greater) cube-type unit robots, each of the N cube-type unit robots comprising: a housing in the shape of a regular hexahedron; a step motor installed in the housing; and a controller installed in the housing and for controlling the step motor. The housing has, on one surface thereof, a mounting groove in which a rotary body rotating by means of a rotating shaft of the step motor can be mounted, and, on the other surface of the housing, a connection groove in the same shape, so that by means of a connector to be mounted in the connection groove, connection to another cube-type unit robot is possible, and the housing has identification marks with different shapes from one another on the respective surfaces thereof.

The invention relates to producing kits for games and souvenirs. The invention consists in a node for connecting moving elements thereof in order to perform a connecting action using two groups of components. A first group of components and a second group of components are connected by means of inserting protrusions, which are positioned along opposing edges of at least two individual components of the second group, in at least two rectangular connecting apertures of one of the individual components of the first group, and which are disposed symmetrically relative to a central aperture on each of the individual components of the first group. The second group of components contains at least two individual components which are made in the form of symmetrical pairs. The result consists in the fastest and most-reliable assembly of the node.

A support assembly for a vehicle includes at least two spherical tires travelling on a road surface and rotating relative to the road surface and the vehicle and a drive system magnetically driving rotation of the tires relative to the drive system itself such that no portion of the drive system physically contacts the tires or the road surface. The tires each have an outer tread layer comprising a material having a first stiffness when dry and a second stiffness when wet, the first stiffness being greater than the second stiffness.

A toy vehicle includes at least a chassis, a front wheel base, and a suspension system. The suspension system adjustably secures the front wheel base to the chassis in a manner that provides two operational modes. In a first mode of the two operational modes, the front wheel base is freely, resiliently supported below the chassis. In a second mode of the two operational modes, the front wheel base is selectively posable by a user over a range of orientations for different types of vehicle mobility. The suspension system retains poses when the toy vehicle is operating in the second mode.

The present disclosure relates to a method of manufacturing a model car body, including preparing a steel mold comprising a core plate with an inner core, a top plate and at least two side plates; attaching at least one pre-fabricated plastic block to a side of the inner core of the core plate; combining the core plate, the top plate and the at least two side plates with each other, wherein a cavity is formed among the top plate, the side plates, the inner core of the core plate and the at least one pre-fabricated plastic block; injecting melted plastic material into the cavity, wherein the melted plastic material is filled with the cavity and the at least one pre-fabricated plastic block is encased by the melted plastic material; solidifying the melted plastic so as to form the model car body, wherein the at least one pre-fabricated plastic block is integrated with the plastic model car body; separating the core plate, the top plate and the at least two side plates from each other; and releasing the model car body with the at least one pre-fabricated plastic block from the mold.

A toy track system for a toy car to move therein and along having a plurality of tube sections including at least first and second tube sections which are connectable endwise together to form part of the toy track system; and a connection module comprising: coupling means having first and second coupling parts which are provided on the first and second tube sections respectively and are inter-engageable with each other to prevent axial separation between the first and second tube sections; and interlocking means having first and second interlocking parts which are provided on the first and second tube sections respectively and are inter-engageable with each other to fix the first and second tube sections in one predetermined angular position relative to each other selected from at least two predetermined angular positions. The car has a wheel, a motor, gears, a presser, principal guiding members and auxiliary guiding members.
