With this construction, the raised portion of the wheel bracket substantially has the same thickness in its longitudinal cross-section. Further, the wheel bracket may be manufactured in a single injection molding with a smooth surface of the front plate.

Abstract: A handle assembly of luggage comprises a handle grip with a push button, two first sliding tubes, at least one pair of second sliding tubes, two support tubes, two first locking means each provided below each first sliding tube, at least one pair of second locking means each provided below each second sliding tube, and a flexible steel cable attached between handle grip and first locking means. This ensures a fully extended handle, a significant increase of the ratio of extendible maximum length to retractable minimum length of handle, and the retracted handle grip rested on the bezel without any gap.

Abstract: A combination carrying handle and retractable handle of luggage is provided wherein the carrying handle is provided on the top center while retractable handle is provided within the compartments. This eliminates protruding tubes of prior art retractable handle system, resulting in an aesthetic design. Further, the combination is capable of being either upright to serve as carrying handle/retractable handle when in use or laid down on either side for saving space in storage.

Abstract: A multi-step positioning device of a trunk pull rod has a pair of pull rods at two sides thereof. Each pull rod has an inner upper rod and an outer lower rod therein. The rod body has two sides of round arc shapes. After engaging, the round arc portions of the two rods are formed with gaps. Porous pieces are placed in the gaps. The porous piece passes through the outer lower rod. The upper end of the outer lower rod is connected to an upper rod sleeve. Protruding buckles at two sides of the upper rod sleeve buckles with the buckling holes with respect to the outer lower rod. The lower end of the inner upper rod is connected to a lower rod sleeve. The slender end of the lower rod sleeve passes through the inner upper rod. Part of the enlarged end portion thereof having an outer diameter identical to that of the inner upper rod passes through the outer lower rod. The top end surface of the lower rod sleeve serves to be inserted by the sliding piece.
