Abstract: A luggage item, a luggage item system and a luggage item adaptor are provided. The luggage item is for use in luggage system comprising a luggage trolley and another luggage item. The luggage item comprises a first side, a second side, a first coupling element and a second coupling element. The second side is opposite the first side and is separated by flanks from the first side. The first side and the second side have an area larger than the areas of the flanks. The first coupling element is arranged at the first side. The second coupling element is arranged at the second side for engaging with a first coupling element of the other luggage item to releasably attach the other luggage item to the luggage item and for engaging with a trolley coupling element of the luggage trolley to releasably attach the luggage item to the luggage trolley.

Abstract: Some embodiments are directed to a foldable vehicle for use as a vehicle if being unfolded, and for use as a trolley if being folded. The vehicle in its folded configuration may also be placed in an upright parking position. The vehicle includes a first side frame coupled to a first wheel, a second side frame coupled to a second wheel and a coupling frame. The coupling frame includes a hinge joint between a first end and a second end of the coupling frame. The first end is hinged to the first side frame and the second end is hinged to the second side frame. When the first wheel translates towards the second wheel, the hinge joint moves from one side of the second wheel to the other side of the second wheel.

Abstract: A foldable vehicle 100 is provided for use as a vehicle if being unfolded and for use as a trolley if being folded. The vehicle 100 in its folded configuration may also be placed in an upright parking position. The vehicle comprises a first side frame 108 coupled to a first wheel 124, a second side frame 102 coupled to a second wheel 112 and a coupling frame 104. The coupling frame comprises a hinge joint 120 between a first end and a second end of the coupling frame. The first end is hinged to the first side frame and the second end is hinged to the second side frame. When the first wheel translates towards the second wheel, the hinge joint moves from one side 128 of the second wheel to the other side 126 of the second wheel.

Abstract: An appliance for making coffee, tea and the like comprises an automatic adjustment unit (22) for adjusting the desired quantity ratio between the quantity of water in a water reservoir (2) and the quantity of substance in a filter holder (4). The adjustment unit (22) can adjust the loadable length of a resilient element (50a) in response to the level of the water in the reservoir 2. The resilient element (50a) is pivotally attached to a lever (5) of the filtering system (3). The rotation of the lever (5) is indicated on a strength indicating scale (10, 11, 12).

Abstract: An appliance for making coffee, tea and the like comprises a simple strength control system (20) having an adjustment unit (22) for adjusting the desired quantity ratio between the quantity of water in a water reservoir (2) and the quantity of substance in a filter holder (4). The adjustment unit (22) can adjust the water level 23 in the water reservoir (2) and the level of immersion (25) of a movable element (6) in a water reservoir (2). The water in the water reservoir exerts a buoyancy force on the movable element (6). The movable element exerts a force (21) on a lever (5). The lever (5) is balanced by a quantity of substance to be filtered in a filter holder (4) and the force (21). The strength of the brew is indicated on a strength indicating scale (10, 12, 12a, 12b).
