Description

ADJUSTABLE BASE FOR MOUNTING HINGES WITH DOUBLE ARTICULATED QUADRILATERALS, FOR DOOR LEAVES OF FURNITURE The present invention relates to an adjustable base for mounting hinges with double articulated quadrilaterals, for door leaves of furniture. With specific, but not exclusive, reference to the furniture sector, hinges with double quadrilaterals are known, which are substantially constituted by a system of articulated levers with associated springs which make it possible to move door leaves that swing with respect to the fixed structure of an item of furniture, between a closed configuration and an open one. Such hinges generally have perforated mounting coupling elements, using threaded elements or the like, inside the door leaf and the structure of the item of furniture. Holes are provided on the door leaf and on the structure of the item of furniture, and the distribution of these holes mirrors that of the holes of the coupling elements of the hinge to be mounted, by inserting threaded connecting elements. Typically these hinges are used to move door leaves that extend horizontally, and they are interposed between the lower face of the upper horizontal wall of the structure of the item of furniture and the upper portion of the inner face of a door leaf. During assembly of the item of furniture, it is necessary to correctly position the door leaf with respect to the structure of the item of furniture, in particular centering it horizontally with respect to them. This requirement is even more evident if two or more wall cupboards are placed horizontally side by side, and their door leaves must not interfere with each other. Furthermore, if at least three wall cupboards are hung side by side, it is necessary to position the respective door leaves so as to space them apart evenly, in pairs. In order to perform the horizontal centering of the door leaf with respect to the compartment of the item of furniture, currently it is necessary to dismount the hinge by unscrewing the corresponding threaded elements and reattach it, if necessary making new holes in the structure of the item of furniture and/or in the door leaf. This mode of operation is not devoid of drawbacks, in that it entails a considerable lengthening of furniture assembly times and consequent increase in the labor costs for centering the door leaf with respect to the item of furniture, since the worker has to proceed by attempts until the optimal position of the hinge is identified. Furthermore the rapidity and precision with which these interventions are performed are considerably influenced by the experience and practicality of the workers. The aim of the present invention is to eliminate the above-mentioned drawbacks in the background art by providing an adjustable base for mounting hinges with double articulated quadrilaterals for door leaves of furniture that enables a horizontal adjustment of the position of the door leaf with respect to the structure of the item of furniture without requiring the dismounting, repositioning and reattachment of the component parts, and therefore with reduced labor times and costs. Within this aim, an object of the present invention is to provide an adjustable base for mounting hinges with double articulated quadrilaterals for door leaves of furniture that enables an easy and reliable adjustment independently of the level of experience of the workers. Another object of the present invention is to provide an adjustable base for mounting hinges with double articulated quadrilaterals for door leaves of furniture that has a structure that is simple and compact, so as to not substantially modify the overall bulk and outline of the hinge in which it is incorporated, and not complicate its installation. Another object of the present invention is to provide an adjustable base for mounting hinges with double articulated quadrilaterals for door leaves of furniture that is able to adapt it to different types of hinges with double articulated quadrilaterals. Another object of the present invention is to provide an adjustable base for mounting hinges with double articulated quadrilaterals for door leaves of furniture that has a simple structure that is easy and practical to implement, safe in use and effective in operation, and of low cost. This aim and these and other objects that will become more apparent hereinafter are all achieved by the present adjustable base for mounting hinges with double articulated quadrilaterals for door leaves of furniture according to claim 1, and optionally provided with one or more of the characteristics recited in the dependent claims. This aim and these and other objects are likewise achieved by a hinge for items of furniture that incorporates the base according to the invention. Further characteristics and advantages of the present invention will become more apparent from the detailed description of a preferred, but not exclusive, embodiment of an adjustable base for mounting hinge
