Abstract:
1. A device for positioning a shelf at different heights within a cell of an appliance having shelf supporting guides arranged at predetermined distances from a bottom of the cell, said device comprising: a coupling element having opposite a first side and a second side, said first side being adapted to engage with the respective supporting guide; an adjusting element coupled to the second side of said coupling element while being moveable vertically with respect to the coupling element, said adjusting element being adapted to receive a respective one of lateral sides of the shelf; and at least a pin which is slidably mounted inside an elongated slot located on the second side of the coupling element and extends outward from said slot; wherein said adjusting element has a closed retaining groove having a plurality of blocking structures corresponding to a plurality of relative vertical positions between the adjusting element and the coupling element; and said pin extends from the slot into said retaining groove and is moveable, in a predefined path inside the retaining groove until said pin is retained by one of the blocking structures, thereby displacing the adjusting element among said relative vertical positions of the adjusting element and the coupling element and thereby facilitating vertical movement of the shelf to a plurality of heights within the cell without having to move the coupling element to the other supporting guides, wherein, when said pin is retained by any one of the blocking structures, said pin is only dislodgeable from said blocking structure by an upward force exerted by a user on the adjusting element.
