Abstract:
Provided herein is an infant wagon having improved convenience of use, wherein the infant wagon includes a front frame, a rear frame, a support frame, side frames, a front handle frame, and a rear handle frame, and is configured such that the axial distance between front wheels and rear wheels thereof is reduced, whereby it is possible to easily switch between a usage mode and a storage mode, such that the structure of the wagon wheel unit is simplified to reduce production costs, whereby it is possible to achieve product competitiveness, such that, when the wheels are worn or damaged, it is possible to easily replace the wheels, and such that the front wheels and the rear wheels are compatible with each other and are interchangeable.

Claim (Index 1):
A wagon having improved convenience of use, configured for carrying a baby, the wagon comprising a foldable main body frame, a wagon wheel assembly, a seat assembly, and a canopy assembly, wherein\n the foldable main body frame ( 100 ) comprises: a front frame, which is a square or rectangular shaped frame disposed at a front end of the foldable main body frame so as to stand up straight in order to support a front of the foldable main body frame; a rear frame, which is a   polygonal shaped frame having an upper frame part, a left side frame part connected to one end of the upper frame part, a right side frame part connected to another end of the upper frame part, and a lower end frame part connected to the left and right side frame parts, and disposed at a rear end of the foldable main body frame so as to stand up straight, the lower end frame part of the rear frame being bent upwards so as to have a trapezoidal shaped recess, the rear frame being configured to support a rear of the foldable main body frame; a support frame, which is a rectangular frame coupled to inside lower ends of the front frame and the rear frame respectively, the support frame comprising a wagon middle shaft disposed at a middle thereof with respect to a forward-rearward direction, the support frame further comprising a front support frame and a rear support frame configured to be folded or unfolded in a symmetrical fashion in order to vary a shape of the support frame according to upward and downward movement of the wagon middle shaft; side frames, each side frame having an upper side frame disposed horizontally and axially coupled to an upper end of the front frame and to an upper end of the rear frame in a symmetrical fashion, a lower side frame disposed horizontally and axially coupled to a lower end of the front frame and to a lower end of the rear frame in a symmetrical fashion, and a vertical connection frame, which stands up straight, having an upper end and a lower end axially coupled to a middle of the upper side frame and to a middle of the lower side frame, respectively; a front handle frame, which is   an inversed U-shaped frame located in front of the front frame, the front handle frame being coupled to a left and a right front portions of the front frame via handle fixing clips so as to stand up straight; and a rear handle frame, which is   an inversed U-shaped frame located at a rear of the rear frame, the rear handle frame being coupled to a left and a right rear portions of the rear frame via handle fixing clips so as to stand up straight, the rear handle frame being configured such that rotation control buttons are coupled to outsides of rotating shafts disposed at a left and a right upper ends of the rear handle frame in order to control an angle of a rear angle adjustment handle in a stepwise manner wherein the wagon wheel assembly comprises: a front wheel drive assembly configured such that a distance between front wheels, coupled to a rear of a left and a right lower ends of the front frame such that support shafts of the front wheels move in a rearward direction to support a front of the wagon, and a center of gravity of the wagon is reduced by 7 to 10 cm; and a rear wheel drive assembly configured such that a distance between rear wheels, coupled to a front of a left and a right lower ends of the rear frame such that support shafts of the rear wheels move in a forward direction to support a rear of the wagon, and the center of gravity of the wagon is reduced by 7 to 10 cm, and wherein the rear wheel drive assembly comprises one of a first rear wheel drive assembly or a second rear wheel drive assembly, wherein the first rear wheel drive assembly is integrally coupled to one side of the front of the left and right lower ends of the rear frame, and has first rear wheels for supporting a lower end of the rear of the wagon detachably coupled to ends of a left and a right rotating shafts of the first rear wheel drive assembly, and wherein the second rear wheel drive assembly is detachably coupled to one side of the front of the left lower end of the rear frame and to one side of the front of the right lower end of the rear frame, and has second rear wheels for supporting the lower end of the rear of the wagon disposed at a rotating shaft coupled to a middle of a lower end of the second rear wheel drive assembly.
