A luggage article comprising a body including a top face, a bottom face, an a plurality of side faces. A first pair of wheels is disposed at the bottom face of the body. A handle has a first operative orientation wherein the handle is disposed within the body and a second operative orientation wherein the handle extracted from the body. A central wheel is functionally associated with the handle, such that in the first operative orientation of the handle, the central wheel is retracted and disposed in or adjacent a face of the body, and in the second operative orientation the central wheel is extracted and extends outwardly from the body.

A castor assembly includes a base, a wheel unit and a rotation shaft. The wheel unit is located under the base and includes a pivot member, an elastic member biased and exposed between the base and the pivot member, and two rollers mounted on the pivot member. The rotation shaft is mounted between the base and the wheel unit and extends through the elastic member. The rotation shaft has a periphery provided with an operation slot. A positioning pin extends through the pivot member and is slidable in the operation slot of the rotation shaft. Thus, the elastic member is exposed outward so that the user clearly sees the elastic member and knows the shock-absorbing function provided by the elastic member.

A wheeled luggage case comprises (a) a storage chamber, (b) a cover defining an opening on at least one side of the storage chamber for providing ready access therein and at least two labyrinth axle-free wheels operatively connected to the chamber for towing the case along a ground surface. The labyrinth axle-free wheel comprises an internal rim, an external rim provided with a ground interface, rollers being rotatably disposed within a roller spacer between the internal and external rims in a uniform circumferential manner by means of a spacer and external covers. A labyrinth type dust passage in the wheel is defined by the rims and the external plates mechanically connected to the internal rim.

A wheel mechanism (10) is disclosed as including an outer wheel (12), two inner wheels (36) received in the outer wheel, and two rubber dampers (24) each separating a respective outer wheel and inner wheel, the rubber dampers being deformable between a first configuration in which the entire outer periphery (37) of the inner wheel is in contact with an inner wall (29) of a recess (28) of the rubber damper and a second configuration in which a part of the outer periphery of the inner wheel is out of contact with the inner wall of the recess of the rubber damper.

A self-propelling item of luggage, for example a suitcase, includes at least a storage area, a drive, a camera, and a data processing device which is designed to recognize an authorized user in a predefined distance range by means of at least one image captured with the camera and on the basis of at least one visual feature extracted from the image, and to actuate the drive so that the item of luggage follows the authorized user in a self-propelling manner at a distance, where the at least one visual feature is characteristic of at least one item of clothing of the authorized user. A method for operating such a self-propelling item of luggage is also described.

A releasable wheel assembly is presented. The releasable wheel assembly includes a base plate and a bracket coupled to the base plate. The bracket includes multiple bosses and each boss includes a hole. An axle passing through the hole of each boss. The axle includes a circumferential groove adjacent to each end of the axle. Additionally, a brace is coupled to the base plate and the axle.

The present disclosure relates to a universal wheel assembly and a suitcase including the universal wheel assembly. The universal wheel assembly includes: a base structure including an upper base and a lower base which form a cavity therebetween; and a wheel bail locked in the cavity in a manner such that the wheel ball is capable of rolling in all directions, wherein a bottom of the lower base is provided with an opening enabling a part of the wheel bail to protrude out of a lower end face of the lower base to form an exposed rolling spherical surface, and an inner diameter of the opening is smaller than a diameter of the wheel ball.

A removable caster system includes a roller, a roller frame and a roller seat, the roller being positioned on the frame via a horizontal axis, the frame being inserted into the vertical shaft hole of the seat through the vertical shaft to form a detachable position; wherein a chute is installed on the upper surface with a trapezoidal stopper; a wire retainer is placed in the chute and is controlled by the movement of its narrowing section or the vertical axis to achieve removable function.
