EXTRACTABLE BASKET-HOLDER STRUCTURE FOR FURNITURE

Abstract: The present invention concerns an extractable basket-holder structure for furniture that comprises a metal rectangular frame (1) supported by a pair of brackers (2) fixed at the internal ends of the frame crosspieces (16) and pivoted to the cabinet (M), while the external ends of the crosspieces (16) are provided with a vertical pin (4) that is inserted and slides inside an horizontal guide (5) fixed on the internal wall of the cabinet door (S).

Description: Description Extractable basket-holder structure for furniture The present patent application concerns an extractable basket-holder structure for furniture, designed to be positioned and hooked in the internal wall of the cabinet door, so that it is automatically extracted when the door is opened and it remains on the internal wall of the cabinet door while moving. Similar structures have been used in kitchen * furniture for a long time, but the mechanisms that are currently used to support and articulate them are quite complex, with high production costs and long installation. To better understand the drawbacks of the current models of extractable basket-holder structures for furniture, it is necessary to describe their structural configuration and fixing method on the internal wall of the cabinet door. First of all, it must be said that the structure is composed of a metal rectangular frame, formed by a lateral pair of rods, usually of telescopic type, connected by two crosspieces at the base and top. The dimensions of the frame are such that it can be exactly housed inside the cabinet on the internal wall of the door. The presence of telescopic rods allows for adjusting the height of the frame in order to use the structure in cabinets with same width, but different height. Series of regularly spaced hooks are located along the two rods, to which wire baskets are hung. On one side the frame is fixed to the cabinet and on the other side it is hooked to the door in an articulated way, so that the door opening or closing causes a simultaneous rotation of the frame in the same direction with respect to the cabinet. The means that are currently used to connect the structure to the cabinet comprise a vertical torsion bar and an identical pair of oscillating levers - one lower and one upper lever - whose end is fixed to hinging pins with vertical axis. One hinging pin is applied on the cabinet base, and the other hinging pin is applied on the cabinet top, both behind the door hinges. The other end of the levers is pivoted at the base and top of the torsion rod, which is inserted through the pair of crosspieces of the metal frame, at little distance from the door hinges. The means that are currently used to connect the structure to the door comprise a pair of cursors coupled with guide rails with horizontal axis, which are screwed at the base and top of the internal wall of the door. Each cursor is joined by means of a connection bolt to one of the crosspieces of the frame near the external end of the crosspiece, that is from the side facing the cabinet door. The rotation of the door causes the simultaneous rotation of the structure located on it because of the connection ensured by the bolt, which in turns can slide freely in horizontal direction with respect to the door, guided by the cursors, which are in turn guided by the rails fixed on the internal wall of the door. The torsion bar synchronises the oscillation of the two levers used to hinge the frame to the cabinet. From the description above it appears evident that the current models of extractable basket-holder structures for furniture are characterised by complex construction and difficult installation, since they require a pair of cursors with guide rails, a pair of connection bolts between the structure and the cursors, a vertical torsion bar and a pair of levers articulated to the torsion bar. Moreover, a functional inconvenience of the models of known type is represented by the fact that most of the weight of the extractable structure is discharged directly on the door, because of the connection bolts by which the weight of the structure stresses the cursors, which in turn discharge the stress on the guide rails that are screwed onto the door. It must be noted that the stress is a considerable one, since the weight of the articles contained in the baskets is added to the weight of the metal structure. This means that the door is subjected to significant harmful stress of flexure, capable of impairing the correct position of the door and its correct articulation. In view of the above, an extractable basket-holder structure for furniture has been devised, characterised by inexpensive manufacturing and easy rapid installation. Moreover, the structure according to the present invention is capable of eliminating any stress of flexure for the door, discharging its entire weight on the cabinet bearing structure. These objectives are met by the extractable basket-holder structure for furniture according to the present invention, which comprises a metal rectangular frame, supported by a pair of brackets rigidly fixed to the internal ends of the crosspieces, whose external end is provided with a vertical pin that is inserted and slides inside a horizontal guide fixed on the internal wall of the door. The two brackets are pivoted to pins with vertical axis fixed at the base and top of the cabinet slightly behind the door hinges. This means that the entire weight of the structure is supported by the two brackets, which in turn discharge it on their pivoting pins. The cabinet does not need to support the structure, since the only connection between the cabinet and the structure is represented by the two pins that protrude from the two crosspieces of the basket-holder structure, which slide inside the guide and transfer no vertical load on the guide, being simply inserted into a horizontal guide slot. For major clarity the description of the basket-holder structure according to the present invention continues with reference to the enclosed drawings, which are intended for purposes of illustration and not in a limiting sense, whereby: - fig. 1 is an axonometric view of the basket-holder structure according to the present invention installed inside a cabinet; - fig. 2 is an exploded axonometric drawing of the basket-holder structure according to the present invention. With reference to the aforementioned figures, the structure according to the present invention comprises a metal rectangular frame (1) formed by a lateral pair of telescopic rods (1a) connected at the base and top by two crosspieces (1b). The dimensions of the frame (1) are such that it can be exactly housed inside the cabinet on the internal wall of the door (S). Series of regularly spaced hooks (1c) are provided along the two rods (1a) and used to hang baskets (C). The peculiarity of the structure according to the present invention consists in the fact that the frame (1) is supported by a pair of identical brackets (2) rigidly fixed at the internal ends of the 'crosspieces (1 b), whose external end is provided with a vertical pin (4) that is inserted and slides in a horizontal guide (5) fixed on the internal wall of the door (S). The two brackets (2) are pivoted on pins (6) with vertical axis fixed at the base and top of the cabinet (M) slightly behind the door hinges. More precisely, each (6) pin is inserted and tuns inside a bush (7) that protrudes from a base (8) with holes (8a) for the passage of screws used to fix the base to the cabinet. The guide (5) consists in a plastic profile with L-shaped section, whose horizontal wing (5a) features a long slot (5b) in which the pins (4) that protrude from the crosspieces (1a) of the frame (1) are inserted and slide.
