The present invention relates to a furnishing element hinge, as well as to a furnishing element.
In particular, the present invention relates to a furnishing element hinge adapted to connect at least rotatably a door to a fixed structure of a furnishing element.
In the field of furnishing elements provided with movable doors, at least rotatably connected to a fixed structure resting on a support surface, a particularly felt need is the balanced adjustment and alignment of each door with respect to another one and/or with respect to the fixed structure.
Usually, the doors are connected to the fixed structure of the furnishing element by a plurality of hinges which connect the door to the fixed structure rotatably or in roto-translation.
The hinges of the known type comprise mechanisms for the adjustment of the relative position between the movable hinge part and the fixed hinge part so as to align the position of the door with respect to another door and/or to the fixed part of the furnishing element.
The alignment of a door to another door and/or to the fixed structure involves, on one hand, a geometric alignment between the doors and/or the geometry of the fixed structure, and, on the other hand, a balanced distribution of the load of the doors with respect to the support surface of the furnishing element.
The doors lose the alignment thereof both due to the natural wear of the hinges and of the position adjustment mechanisms, as well as due to slight geometric variations of the fixed structure of the furnishing element and/or of the support surface on which the furnishing element rests.
The geometric alignment alone is not sufficient to ensure the balanced distribution of the door loads, in fact, if the support surface of the furnishing element is not perfectly flat, it may happen that the doors, although geometrically aligned with the geometry of the fixed structure, do not maintain the opening position or, vice versa, the closing position of the fixed structure defined compartment.
Over time, and as the number of opening and closing cycles of the doors of a furnishing element increases, the alignment of the doors is lost, and a periodic adjustment of the hinges is required.
Furthermore, usually, the hinges of the known type are connected in a plurality of points to the shoulder of the fixed structure, and thus they stress such shoulder by disadvantageously accelerating the variations of the geometric type of the fixed structure, thus making the adjustments of the hinges for aligning the door more frequent.
A correct adjustment of the hinges of the known type is far from simple, since it must ensure not only a geometric alignment between the doors and the fixed structure, but also a distribution of the loads of the doors as balanced as possible with respect to the planarity conditions of the support surface of the furnishing element.
Such adjustment is therefore so complicated that many users are forced to turn to highly expensive specialized furniture assemblers.
In the context of furnishing elements, the need is therefore felt to devise devices for opening and closing doors with respect to the fixed structures which they are connected to, which maintain the alignment of the doors as much as possible over time and which thus reduce the frequency of the adjustments of the alignment and which are easily adjustable by an average user.
Therefore, the problem underlying the present invention is that of devising a furnishing element hinge which has structural and functional features such as to satisfy the aforesaid needs while overcoming the drawbacks mentioned with reference to the prior art.
The present invention aims to provide a furnishing element hinge which allows an adjustment of the position of a door with respect to the fixed structure to which it is connected and with respect to the support surface on which the furnishing element rests which is, on the one hand, simplified and, on the other, which allows to maintain the correct adjustment of the position of the door in a permanent manner, limiting the number of interventions required to adjust such position over time.
This and other objects and advantages are achieved by a furnishing element hinge according to claim 1, as well as by a furnishing element according to claim 8.
Some advantageous embodiments are the subject of the dependent claims.
From the discussion of the claimed solution, it emerges that the suggested solution allows to simplify the adjustment of the position of the door by freeing, with a single device, the adjustment of the position of the door with respect to the support surface of the furnishing element from the adjustment of the position of the door with respect to the geometry of the fixed structure.
Furthermore, the suggested solution maintains the geometric alignment between a door and the fixed structure to which it is permanently connected, preventing the door from stressing the fixed structure with the weight thereof and limiting the occurrence of geometric variations in the fixed structure, which would lead to an increase in the frequency of the maintenance of the door position alignment with the geometry of the fixed structure.
The suggested solution allows to easily and intuitively correct planarity defects on the support surface of the furnishing element and provides highly precise and easy-to-use door position adjustment mechanisms.
Further features and advantages of the invention will become apparent from the following description of preferred embodiments thereof, given by way of non-limiting example, with reference to the accompanying drawings, in which:
In accordance with a general embodiment, a furnishing element hinge is indicated by reference numeral 1.
Said furnishing element hinge 1 is adapted to movably connect a door 102 to a fixed structure 101 of a furnishing element 100.
Said structure 101 rests on a support surface 104 and delimits a compartment 103.
Said furnishing element hinge 1 comprises a fixed hinge part 2, adapted to be connected to the fixed structure 101.
Said furnishing element hinge 1 further comprises a movable hinge part 3, adapted to be connected to the door 102.
Said movable hinge part 3 is movable at least rotatably with respect to the fixed hinge part 2 at least between a first position, adapted to open said compartment 103 and a second position, adapted to close said compartment 103.
In other words, in said second position of the movable hinge part 3, the door 102, to which the movable hinge part 3 is connectable, is positioned, with respect to the fixed structure 101, closing the compartment 103, while in said first position of the movable hinge part 3, the door 102 is at least rotated with respect to the fixed structure in one of the possible opening positions of said compartment 103.
Said furnishing element hinge 1 comprises a support foot 4.
Said support foot 4 is connected to a fixed hinge part 2.
Said support foot 4 is adapted to rest on said support surface 104 to unload at least the weight of said door 102 directly onto the support surface 104.
In accordance with an embodiment, said fixed hinge part 2 is adapted to unload the weight of the door 102 onto the support foot 4, avoiding unloading the weight of the door 102 onto the fixed structure 101.
Therefore, the furnishing element hinge 1 also acts as a support structure for the door 102 and thereby the weight of the door 102 weighs on the support foot 4 and not on the fixed structure 101, thus avoiding stressing it.
According to an embodiment, said fixed hinge part 2 comprises a hooking portion 5 adapted to be connected to said fixed structure 101.
Said hooking portion 5 has an apical surface 5a adapted to be connected to said fixed structure 101.
Said hooking portion 5 has a basal surface 5b diametrically opposite with respect to said apical surface 5a.
Said basal surface 5h is adapted to face said support surface 104.
In accordance with an embodiment, said hooking portion 5 has a shaped lateral surface 5c adapted to be housed in an undercut of said fixed structure 101.
In accordance with an embodiment, said hooking portion 5 comprises a plurality of fastening holes 22, passing through a direction transverse between said apical surface 5a and said basal surface 5b.
Said plurality of fastening holes 22 are adapted to house a respective plurality of fastening elements to the fixed structure 101 of said furnishing element 100.
In accordance with an embodiment, said support foot 4 protrudes from said basal surface in the direction of said support foot 104.
In accordance with an embodiment, said support foot 4 is movable between a minimum extension position and a maximum extension position with respect to said basal surface 5b.
According to an embodiment, said support foot 4 is adjustable in a direction transverse with respect to said support surface 104.
In accordance with an embodiment, said support foot 4 is adapted to unload at least one part of the weight of said fixed structure 101 onto said support surface 104.
In accordance with an embodiment, said support foot 4 comprises a stem 19 connected to a flat support base 20 configured to rest on said support surface 104.
In accordance with an embodiment, said stem 19 is connected to said flat support base 20 in a jointed manner.

According to an embodiment, said threaded hole 21 is a hole passing through said hooking portion 5 in a direction transverse to the basal and apical surface.
In accordance with an embodiment, said support foot 4 is movable in rotation in the respective threaded seat between said minimum extension position and said maximum extension position with respect to said basal surface 5b.
Therefore, when the furnishing element hinge 1 is connected to the furnishing element 100, the support foot 4 acts, on the one side, as a structure supporting said fixed structure 101 by unloading the weight of a part of it on the support surface 104, and, on the other side, it acts as an element for the adjustment under load of the distance between said fixed structure 101 and said support surface 104.
