#CMT# #/CMT# The device has a connecting unit (L2) connecting a chassis (3b) and a carrier (2) to ensure characteristics that include minimum degree of freedom of a ball-joint connection of an origin point (B), an angle between a segment (AB) connecting the origin points (A, B) and a horizontal plane (H) ranges between 15-75 degrees, the point (B) is not confound with the point (A), and a ratio of length (X-G) to length (X-B) is less than 0.5, where former length is a length between the point (A) and a center of gravity (G) on a horizontal plane (H) and latter length is a length between the points (A, B). #CMT# : #/CMT# The origin point (B) is not confound with the origin point (A) when the segment (AB) is perpendicular to a segment (AC) connecting the origin point (A) and an intersection point (C), and center of gravity (G) is below a normal plane (k). #CMT#USE : #/CMT# Device for maintaining a load between a support and a carrier in stable equilibrium for a baby stroller, golf bag or caddie, wheelbarrow, tow dolly, and luggage carrier (all claimed). #CMT#ADVANTAGE : #/CMT# The configuration of the device permits to use and fold the device in an easy and safe manner. The device is compact, inexpensive, stable and reliable, and has reduced weight and encumbrance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a load maintaining device.
