A self-propelled toy, includes a “drive and control” module and a housing in the shape of a dinosaur, animal or human sliding sports player. An axle with wheels is attached to the drive and control module in the housing. A pull-back mechanism includes a motor drive/driven gear that drivingly connects to the axle drive/driven gear, wherein upon pulling back the toy body with the wheels touching the ground, the pull-back mechanism generates and stores mechanical potential energy. Upon release of the toy body, kinetic energy drives the toy in a direction opposite that of the pull-back direction. A controller is connected to the pull-back mechanism and is electrically connected to at least one light emitting diode (LED) in the toy body. When the toy is released to allow the toy to move forward, the LED is powered to generate a light signal and optionally a sound transducer generates a sound.

A toy truck having a crane arm, comprising multiple telescopic components to form a crane extension mechanism. The crane arm extension mechanism includes a crane arm that is capable of telescopically extending based on the air pressure manually provided to fill telescopic members of the crane arm. To telescopically extend the crane arm, a crank is rotated which causes an air pump to pump air into the crane arm. As the air pressure in the crane arm increases, the crane arm telescopically extends.

A walking toy in which if a torso is moved forward walking motion is performed has the torso, two legs. The walking toy includes a crank member having a pair of crank eccentric shafts. Each of the legs has a motion member giving rotational force to the crank member when the torso moves forward. Each of the motion members has an eccentric shaft connecting part pivotably connected to the corresponding crank eccentric shaft, a torso cooperation part, and an action part on which force received from the walking surface act. Projections are formed at the torso cooperation part, while grooves are formed at the torso. If the action part of the one leg moves rearward, the motion member moves to thereby impart rotational force to the crank member and, the other leg is moved forward due to rotation of the crank member, and then contacts the walking surface.

The present invention relates to a toy gun having a bolt configured to move forward or backward such that a recoil and a following thrill can be experienced as in the case of an actual gun. The toy gun according to the present invention comprises: a body for firing dummy bullets; a bolt assembly provided inside the body so as to move forward or backward in the process of loading and firing the dummy bullets; and a driving portion provided inside the body so as to drive the bolt assembly in order to load and fire the dummy bullets, wherein the driving portion comprises a ratchet gear configured to receive power from a driving motor that drives the driving portion, a piston gear that receives power from the ratchet gear and moves the bolt assembly backward, and a ratchet assembly that selectively transfer power, which is transferred to the ratchet gear, to the piston gear; the ratchet assembly comprises a piston gear cap that penetrates the ratchet gear and is coupled to the piston gear while the ratchet gear remains fitted to the center of the piston gear cap and a ratchet pole configured to slide in a direction with regard to the piston gear cap; and an engaging groove, into which the ratchet pole is inserted, is provided on the inner surface of the piston gear such that, as the ratchet pole is inserted into and released from the engaging groove, power is selectively transferred from the driving motor to the piston gear.
