ABSTRACT:
A carriage rack has two posts, two swivel arms, two elastic elements, a luggage holding rod, a bracket, and casters. The two posts are spaced in a parallel manner and provided with pivoting portion. Each of swivel arms is composed of a cylindrical portion and inner and outer lugs extending rearwards from the cylindrical portion, which is provided with an opening. The inner lug is furnished with a recess, a slant, and a baffle. The swivel arm is fastened to the bottom end of the post by means of its cylindrical portion which receives the post in such a manner that the pivoting portion of the post extends out of the opening of the cylindrical portion so as to permit the positioning of the swivel angle of the swivel arm. The elastic elements are used to drive the two swivel arms to move. The luggage holding rod has two upright legs pivotally fastened to the pivoting portions of the posts in such a manner that they urge the slants of inner lugs of the swivel arms so as to enable the swivel arms to move outwards. The bracket is fastened to the luggage holding rod in such a way that it keeps the two upright legs of the luggage holding rod to remain perpendicular to ground surface at the time when the carriage rack is in use.
