A luggage item (1) comprising a rigid, essentially rectangular box (3), comprising an essentially planar floor and two longer and two shorter sides, there being mounted on the major axis of the floor a telescopic pulling member (17) equipped with a pulling handle (18), characterised in that (a) the pulling member is mounted externally on the floor by means of a pivot (8) and can move through a fixed arc, the extremities of which arc are appropriate for sliding a luggage item on a staircase, the pulling member being lockable in a position coinciding with the major axis; (b) the luggage item comprises a secondary retaining means that prevents the pulling member being pulled out of the plane of the arc; and (c) the longer sides are provided with means (14) allowing sliding movement on a staircase. The luggage item can easily be pulled up and down stairs.

An object transfer system (OTS) for a flight of steps for transporting an object on the flight of steps is disclosed. The OTS may include a rail positioned in place of a handrail on the flight of steps, a trolley assembly movably attached to the rail, and an object carrier attached to the trolley assembly. The rail has a rail length and the object carrier is configured to hold the object. Additionally, the trolley assembly is configured to transport the object held by the object carrier along the rail length.

Device for manually lifting a load with a lever for a cart, suitcase and the like, making it easier to ascend and descend staircases and various obstacles, said device comprising two parts:a first part comprising: a frame (1) secured to wheels (2), the wheels (2) and the handles (3) being fixed to the frame (1),a second part comprising: a load support (4) secured to wheels (5), the wheels (5) and a load (12) being mounted in a fixed manner on the load support (4), the second part being able to slide with respect to the first part by the action of a telescopic lever arm (10) in order to ascend a step of a staircase in two phases, the telescopic lever arm (10) being fixed to the handles (3) by an articulation (9), a second articulation (8) connecting the telescopic lever arm (10) to a transmission (6) which is in turn connected by a third articulation (7) to the load support (4) of the second part.

An extendable sled device for transporting luggage or other bulky objects up sets of stairs with less effort. The extendable sled device is integrated with, or attached to, the object being transported. The extendable sled device has an extendable sled controlled by an extension mechanism. The extendable sled is lowered by the extension mechanism when in use, and retracted when not in use. The extendable sled can also have one or more stopper mechanisms, which are used to arrest the luggage on a set of stairs if a user accidentally releases the luggage midway up the flight. The stopper mechanisms prevent the luggage from falling back down the steps and potentially injuring people.

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.
