Shock-absorbing wheels are arranged at four corners of a bottom of the trolley bag.

An exemplary embodiment of the present invention provides a rod rotation apparatus, including: a rod having at least one first helix or at least one second helix coupling portion; a movable member having at least one first helix coupling portion or at least one second helix coupled with the at least one first helix or the at least one second helix coupling portion; a handle extender having a structure of one or more stages, including a first-stage extender; a handle coupled to the top of the handle extender; and a traction member connected between the movable member and the handle or between the movable member and the handle extender.

A stabilized luggage article is disclosed. In one practice, the luggage article comprises a plurality of swiveling wheel assemblies, each assembly comprising one or more wheels having a horizontal axis of rotation and mounted to a pivot member, such as a pivot post that has a vertical axis of wheel rotation; the vertical axis of rotation is laterally spaced from the horizontal axis of rotation and is projected outwardly toward the front wall of the luggage but not beyond it, the pivot post extending downwardly at least to the level of the horizontal axis of wheel rotation, preferably beyond it for further increased stability.

A system of interconnecting luggage includes first and second luggage items. The first luggage item has a handle about an upper end and rolling elements about a base, and is tiltable about a rotational axis of the rolling elements by the handle. The second luggage item also has rolling elements about a base. Each of the first and second luggage items have integral mutual engagement and disengagement elements configured to provide, when the first and second luggage items are mutually engaged, a substantially rigid mechanical connection that maintains the first and second luggage items in relative spatial arrangement such that when the system is in a stable arrangement, the rolling elements of the first and second luggage items contact an underlying planar substrate, and the first luggage item is maintained at a tilt angle relative to the underlying planar substrate.

A support device for wheels of transportable containers, such as trolley cases or the like, has at least two parts fixed to each other, including a first and a second part, so that the two parts have a relative movement therebetween, from a condition of maximum approach to a condition of maximum distancing. The first part is integral with the container and the second part is formed by an arm adapted to support at least one wheel, rotatably fixed to the arm. Furthermore, the first and the second part each have at least one magnetic element, and the at least two magnetic elements are arranged in opposite positions so as to generate a magnetic force of repulsion between the two parts, aimed at permanently maintaining the two parts in a condition of maximum distancing.

According to an embodiment, a carrier with retractable wheels comprises a main body including a storage space and an inlet hole formed in a bottom to be open or closed by a sliding plate and a moving unit having a body pivotably provided in the inlet hole and a wheel attached to an end of the body. When the inlet hole is closed by the sliding plate, the moving unit is pivoted up, the wheel is supported by the sliding plate to be positioned inside the inlet hole and, when the inlet hole is open, the moving unit is pivoted down to stick out of the inlet hole.

The invention provides a luggage apparatus (10, 110) capable of being used in normal mode and alternately in child carrying mode. Luggage apparatus (10, 110) has a top (12, 112) a bottom (14, 114), a front (16, 116), a rear (18, 118) and opposing sides (20, 120) and (22, 122). The dimension between the front (16, 116) and the rear (18, 118) is longer than the dimension between the opposing sides (20, 120) and (22, 122). A first wheel means (24, 124) is located in the vicinity of the front (16, 116). The first wheel means (24, 124) is used to wheel luggage apparatus (10, 110) in normal mode. A second wheel means (28, 128) is located in the vicinity of the rear (18, 118) and, in conjunction with the first wheel means (24, 124), can be used to wheel the luggage apparatus (10, 110) in child carrying mode. A child seat (44, 144) is foldable within the luggage apparatus (10, 110) in normal mode and unfoldable in child carrying mode to be positioned on or above the top (12, 112) of the luggage apparatus (10, 110). In child carrying mode, the longer dimension is substantially parallel to the ground supporting the luggage apparatus (10, 110) and the unfolded child seat (44, 144) is positioned so that the centre of gravity of the child seat (44, 144) and any child thereon is substantially between the front (16, 116) and the rear (18, 118).

The present invention is directed to a suitcase which is made of a metal material such as aluminum or made of synthetic resin or fabric, is formed in a quadrangular shape, and is provided with a zipper or one-touch locking device along a center thereof so that a suitcase body can be selectively opened and closed, and in which a handle is installed to be retractable on the top surface of the suitcase body, wherein an auxiliary moving means configured such that auxiliary casters are rotated and deployed by the extension of a handle is installed on the suitcase body so that the suitcase body can be laid down and moved, and a loading guide is installed to be foldable on the suitcase body so that a load can be loaded thereonto in the state where the suitcase body is laid down.

A travel bag is provided. The travel bag comprising: a frame having at least three wheels attached thereto, each of the wheels being configured to be contact to a ground; a case being configured to have an empty space to receive objects and also being configured to be disposed on the frame; and a pivot axis being located on or above the frame, the pivot axis being defined by two contact points or a contact line connecting the case and the frame. The case disposed on the frame is allowed to pivot on the pivot axis to draw a trajectory of an arc or a circle. All of the wheels are configured to be maintained as being continuously contact to the ground, regardless of the case's pivoting around the pivot axis.

An method and system of and for releasably affixing a luggage to a column via brackets including posts and apertures either permanently or releasably affixed to the luggage and column.
