Title:
TRANSPORT DEVICE HAVING MULTI-AXIS CONNECTOR FOR SMOOTH BALANCE MAINTENANCE
Document Type and Number:
WIPO Patent Application WO/2018/066758
Kind Code:
A1
Abstract:
The present invention relates to a transport device having a multi-axis connector for smooth balance maintenance and, more specifically, is useful since a connector (300) for connecting a movable frame (200), of the transport device, having a balance maintenance function and a main frame (100) substantially performing a loading function is formed to have multiple axes such that the movable frame (200), during movement, is not restricted and can freely move due to the multiple axes, and when a trailer (500) is selectively coupled to the rear of the transport device, a connection part (400), which has a rotary shaft part (410) axially provided at one side of the main frame (100) positioned farther in front of a wheel axis of the transport device, and the trailer (500), which has a space formed at the rear thereof and enabling loading therein and has one side connected to one side of the connection part (400), are provided such that when a path is changed during movement, the center of gravity of the trailer (500) is positioned farther in front of the axis of a wheel (201) so as to enable forward sliding to be prevented, and thus, during movement on uneven ground, a moving part can freely move so as to ensure smooth movement instead of a restricted movement, the center of gravity is positioned farther in front of the axis of the wheel during a directional change so as to prevent sliding, thereby preventing a rollover, and restoring force is provided by means of to an elastic member so as to provide stability and convenience of use.
