A toy is disclosed for a segmented tube track kit. The toy comprises a tube, comprised of reversibly attachable tubes. In one embodiment, the tube segments are held together frictionally. In another embodiment, tube segments are held together by locking mechanisms consisting of projections and cutouts. The toy vehicle in the kit has a drive wheel which is forced up away from the body of the car and against the inner walls of the tube by resilient members. In another embodiment, the vehicle has a tumbler wheel at the front of the car.

A form changing toy includes a power source, a power transmission mechanism, an operation part, a switch, a movable part, a locking mechanism, and a connecting part. The operation part is configured to perform a predetermined operation by the power. The switch is configured to be moved between a first position to a second position, and being urged to the second position. The locking mechanism is configured to lock the movable part at the first position when the movable part is manually moved from the second position to the first position, and is configured to release locking by the power when the predetermined operation continues. The connecting mechanism is configured to operate the movable part by connecting the movable part and either one of the power transmission mechanism and the operation part when the movable part moves to the second position.

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.

A gear mechanism having a shuttle gear adjacent both an auxiliary gear and an action gear and a cam plate, having a shuttle lock adjacent the shuttle gear and including a cam follower riding back and forth along a first cam pathway with an action element in mechanical communication with the action gear. A motor operates the shuttle gear with rotation of the motor in a first direction rotating the shuttle gear into engagement with the auxiliary gear, activating the shuttle lock to maintain the engagement throughout a predetermined rotational range of the cam plate and rotating the cam plate back and forth driving controlled back and forth movement of the auxiliary elements, with rotation of the motor in a second direction rotating the cam plate beyond the predetermined range releasing the shuttle lock.

A gear assembly for a toy vehicle is disclosed. The gear assembly may be selectively placed in a drive position in which a first set of wheels and a second set of wheels are connected to the motor through a first gear train and a second gear train, respectively. The gear assembly may be selectively placed in a freewheel position in which the first set and second set of wheels are disconnected from the motor. The gear assembly is switched from the drive position to the freewheel position using a lever that pivots to move a gear in the first gear train to disconnect the gear and break the first gear train when a gear is moved in the second gear train to disconnect the gear and break the second gear train. Through the lever, the first and second gear trains are positioned in concert.

Provided is an assembly connection member including a body, and a cylindrical rotary insertion member inserted in the body. The cylindrical rotary insertion member includes a first cylindrical rotary insertion member inserted to an opening of a circular shape formed in a center of an upper body, a second cylindrical rotary insertion member inserted to an opening of a circular shape formed in a center of a side surface of the upper body, and a third cylindrical rotary insertion member inserted to an opening of a circular shape formed in a center of an opposite side surface of the upper body.
