The present disclosure is about assemblies containing shiftable parts like three sided open-frames or independent bars with stub-axles. In some embodiments shiftable parts are designed to slide within encompassing tubes. In other embodiments shiftable parts are designed to be turnable by attaching them on pivots. These shiftable components are used for mounting general wheels or multi-wheel star assemblies on them. Such assemblies can be either attached to or built into movable objects like luggage or robots to facilitate their movement over stairs. When the wheels are positioned to keep the body of the movable object away from the edges of the stairs, the object can be moved upstairs and also downstairs without getting scratched. When the wheels are shifted to another position, the objects can be easily moved over flat surfaces. One of these positions will be for storing the object in lesser space.

The present invention relates to a transport device (2) for overcoming a step-like obstacle (1), wherein the transport device (2) is movable in a traveling position and has a support structure (3) for supporting a load (4) to be transported. The task of the transport device (2) according to the invention is to overcome the difference in height of the step-like obstacle (1) by means of a leverage effect, whereby the transport device (2) should be usable on short stair steps. This task is accomplished in that via a tilting movement of the support structure (3) towards the step-like obstacle (1) a support element (10) of the transport device (2) can be set down on an upper surface (1a) of the step-like obstacle (1) and the support structure (3) can be tilted over the support element (10) set down in this way, and in that the transport device (2) has a connecting element (11), and in that the transport device (2) has a guide element (12) connected to the support structure (3), and in that the connecting element (11) is guided by the guide element (12), and in that the support element (10) is connected to the connecting element (11) in an articulated manner, and in that the connecting element (11) can be pivoted from a first into a second position relative to the support element (10) and brought from a first into a second position relative to the guide element (12), while the support structure (3) is supported against the upper surface (1a) of the step-like obstacle (1) via the support element (10).

Provided is a transportation device for loading a cargo and moving in a moving direction, comprising: a bed for loading a cargo thereon; four leg parts for being able to receive a part of a weight of the bed individually; a movable part for moving the leg parts individually to change relative positions with respect to the bed individually; and a control part for controlling the movable part for the four leg parts individually, wherein the control part is for changing the relative position of at least one of the four leg parts with respect to the bed within a range in which a center of gravity of the bed is located inside a profile of a horizontal triangle made by three leg parts among the four leg parts as apexes, causing the three leg parts to support the bed and releasing one remaining leg part from supporting the bed.

A foldable box body and a shopping cart using same are provided. The foldable box body includes a box plate, which forms an accommodating space. The box plate includes a front box plate and a rear box plate. A flexible folding portion is provided between the front box plate and the rear box plate. The front box plate and the rear box plate are foldable by means of the flexible folding portion. The foldable box body is provided on the shopping cart.

A transport device, in particular for transporting luggage, includes a support structure, a coupling element or a handle and a rolling body in addition to a transport container for receiving objects, in particular luggage. The rolling body has a rotational symmetry and is configured such that it tapers in diameter towards the ends along the axis of symmetry. Because of the arrangement and design of the transport container, the transport device is self-stabilizing in operative use.

A pallet lift includes a base and a deck extending forward of the base. Load wheels support the deck. A platform above the deck is pivotable relative to the base. The platform has an upper support surface for supporting objects thereon. The platform may be pivoted as the pallet lift travels on an inclined surface, such as a truck ramp, in order to keep the platform relatively level relative to gravity to increase stability.

Provided is a lightweight crawler unit which is capable of swiveling, suitable for a trolley for bad roads, and used for transportation in muddy places such as snowy roads, sandy ground, and fields, and disaster sites. A crawler includes a plurality of inner attachments provided inside thereof toward a frame to have a band-shape, overhang edges 70 protruding in a left and right direction of a rail provided on a circumference of the frame, and overhang edges 34 protruding in a left and right direction of each of the inner attachments, in a space K enclosed between the overhang edges 34 facing each other, the overhang edges 70 are inserted, the overhang edges 34, 70 are set in a positional relation in which they overlap with each other in an up and down direction, and the crawler circulates around pulleys, while the inner attachments are restricted along the rail.
