Such purposes, as well as others which will appear more clearly hereinafter, are fulfilled by a system according to what is herein described, claimed and/or shown. Advantageous embodiments of the invention are defined in accordance with the dependent claims.

Brief description of the drawings

Further features and advantages of the invention will become more evident by reading the detailed description of some preferred but not exclusive embodiments, shown by way of non-limiting example with the help of the annexed drawing, wherein:

FIG. 1 is an exploded view of the system 1;

FIGs. 2 and 3 are side views of the system 1 at different operating phases;

FIGs. 4 and 5 are schematic views of the system 1 in further operating phases;

FIGs. 6 and 7 are enlarged schematic views of some details of system 1.

Detailed description of a preferred embodiment

With reference to the figures, a system 1 for the rotatable coupling of at least one closing element D, such as a door, a shutter, a gate, a window or the like and a stationary support structure S for example such as a wall and/or frame of a door or window and/or a support pillar and/or the floor is described.

In particular, the closing element D may rotate between at least one closing position and at least one opening position.

Thus the system 1 may comprise a hinge device 5 anchorable to one of the stationary support structure S and the closing element D and an mounting plate 100 anchorable to the other of the stationary support structure S and the closing element D.

Preferably, as shown in the annexed figures, the hinge device 5 may be anchored to the closing element D, for example the door, while the mounting plate 100 may be anchored to the support structure S, for example to the floor or ceiling.

The hinge device 5 may be of any type. For example, it may be an opening and/or closing hinge of the closing element D, or a control hinge, or a simple movement hinge. In particular, in case the closing element D is a glass door or shutter, the hinge device 5 may be a patch fitting.

The hinge device 5 may particularly comprise a hinge body 10 and at least one pivot 20 which may define an axis X.

The hinge body 10 and the pivot 20 may be reciprocally coupled to reciprocally rotate around said axis X between at least one open position corresponding to the open position of the closing element D and at least one closed position corresponding to the closed position of the closing element D.

The hinge device 5 and the mounting plate 100 may be reciprocally coupled.

Suitably, the pivot 20 may include at least one coupling portion 21 protruding from the hinge body 10, while the mounting plate 100 may comprise at least one seat 111 for such coupling portion 21 of the pivot 20.

In particular, as shown in FIG. 1, the mounting plate 100 may comprise a plate- shaped body 110 which may include the seat 111. Preferably, the mounting plate 100 may consist only of the plate-shaped body 110.

In this case, the mounting plate 100 may be extremely low-cost and easy to mount.

On the other hand, the mounting plate 100 may consisting of several constituent parts assembled each other to form a unitary plate-shaped body 110.

According to a particular aspect of the invention, the plate-shaped body 110 may have an elongated shape so as to define an axis Y substantially perpendicular to the axis X. In particular, the hinge body 10 may have a predetermined width LI, while the plate-shaped body 110 may have a width L2 substantially equal to or less than the width LI of the hinge body 10.

For example, the width LI of the hinge body 10 may be 20 mm to 30 mm, preferably may be about 25 mm, equal to the width L2.

In this way, the system 1 may be particularly low-bulkiness and may give to the same system 1 a high aesthetic appeal.

According to a particular aspect of the invention, the seat 111 may have an elongated shape so as to define an axis Y' substantially perpendicular to the axis X. Possibly, the axis Y' may be substantially parallel to the axis Y of the hinge body 110. Preferably, the axes Y and Y' may coincide each other, as in the annexed claims.

The coupling portion 21 of the pivot 20 and the seat 111 may be reciprocally configured so that the former may be mobile within the latter along the axis Y'.

In particular, as schematically shown in FIG. 7, the seat 111 may have a pair of guide walls 112, 113 for guiding the sliding of the portion 21 of the pivot 20 along the axis Y'. More in detail, each of the guide walls 112, 113 may be reciprocally faced to a corresponding side wall 22, 23 of the coupling portion 21. According to a particular aspect of the invention, the seat 111 and the coupling portion 21 may be reciprocally dimensioned so as to allow only the reciprocal sliding along the axis Y' and therefore the slider of the hinge device 5 along the same axis Y'.

In other words, once the seat 111 and the pivot 20 are coupled, the guide walls 112, 113 of the former and the side walls 22, 23 of the latter may be reciprocally in contact so as to prevent the reciprocal movement both in a direction transverse to the direction defined by the axis Y' and in a rotary direction.

In particular, the coupling portion 21 may have a predetermined thickness W2, and the seat 111 may have a width Wl substantially equal to the thickness W2 of the coupling portion 21.

For example, the width Wl of the seat 111 and the thickness W2 of the coupling portion 21 may be 6 mm to 12 mm and preferably may be about 9 mm.

In particular, the width Wl of the seat 111 may be significantly lower than the width L2 of the plate-shaped body 110. For example, the ratio between the width Wl of the seat 111 and the width L2 of the plate-shaped body 110 may be less than 0,5, preferably less than 0,4.

As shown in Figs. 4 and 5, the seat 111 may further comprise at least one pair of bottom walls 115, 116 which may define the end position for the coupling portion 21 of the pivot 20. In other words, the pivot 20 may slide along the axis Y' between a first end stroke position in which abuts the bottom wall 115 and a second end stroke position in which abuts the opposite bottom wall 116.

According to another aspect of the invention, the plate-shaped body 110 may comprise means 120 to fasten the sliding of the portion 21 within the seat 111 passing through the guide walls 112, 113.

In particular, said fastening means 120 may comprise at least one adjusting screw

121 having a working end 122 susceptible to engage a corresponding side wall 22, 23 of the coupling portion 21 of the pivot 20 and a operateable end 123 accessible from outside by an operator.

Preferably, as particularly shown in FIG. 7, the fastening means 120 may comprise a plurality of adjusting screws 121, 121', for example a pair of them, placed on opposite sides with respect to the seat 111. More specifically, each adjusting screw 121, 121' may have a respective working end 122, 122' facing a respective side wall 22, 23 and a respective operating end 123, 123' accessible from outside by the operator.

The adjusting screws 121, 121' may act along a respective axis Z, Z' substantially transverse to the axis Y' and preferably perpendicular to the axis Y'.

Suitably, the plate-shaped body 110 may comprise passing through holes 114, 114' passing therethrough for the adjusting screws 121, 121' which may in turn have an axis corresponding to respectively the axis Z and the axis Z' to guide the latter.

In particular, when at least one of the ends 122, 122' of the adjusting screws 121, 121' abut the respective side wall 22, 23 of the coupling portion 21 of the pivot 20, the latter may be fastened inside the seat 111 in any position between the first and second end stroke position.

Thanks to these features, an accurate adjustment of the sliding along the axis Y' and more generally along the hinge device 5 may be possible.

The plate-shaped body 110 may be solidly coupled with the stationary support structure S and may include means 140 for adjusting its position with respect to the same stationary support structure S.

The adjustment means 140 may comprise an element for the rotatable fastening of the plate-shaped body 110 to the stationary support structure S, for example a pivot or a screw 141 interacting with a corresponding circular slot 119. In particular, such screw 141 may define a rotation axis X' for the plate-shaped body 110, which may be essentially parallel to the axis X.

Thanks to the features above mentioned, the pivot 20 (thus the hinge device 5) may slide along the axis Y' (FIGs. 2 and 3) and may rotate around the axis X' (FIGs 4 and 5).

According to a further aspect of the invention, the adjustment means 140 may include means 142 for limiting the rotation of the plate-shaped body 110 around the axis X'.

Such a feature may be particularly advantageous if the system 1 is mounted on a frameless glass door.

For example, the limiting means 142 may include an elongate slot 143 on the platelike body 110 to remain facing the stationary support structure S. In particular, an elongated slot 143 may be defined by a recess in the plate-shaped body 110.

Suitably, the limiting means 142 may comprise an abutment element 144, such as a pivot, fixed to the stationary support structure S and interacting with the elongated slot 143. To this end, the abutment pivot 144 may have the expanded upper part into the elongated slot 143.

In particular, the latter and the abutment element 144 may be reciprocally coupled so that upon the rotation of the plate-shaped body 110 around the axis X' the elongate slot 143 moves with respect to the abutment element 144 between at least one first end stroke position (FIG. 4) and at least one second end stroke position (FIG. 5).

More specifically, as shown in FIGG. 4 and 5, the plate-shaped body 110 and thus the axis Y may rotate of a predetermined angle a around the axis X' with respect to the axis Y" passing through the abutment element 144 and the screw 141.

According to a further aspect of the invention, as particularly shown in FIG. 6, the limiting means 142 may include at least one adjusting screw 145, preferably a pair of adjusting screws 145, 145' passing through the plate-shaped body 110 and acting within the row 143 to vary the position of one and/or both the end stroke positions.

As stated above for adjusting screws 121, 121', the adjusting screws 145, 145' may have a respective working end 146, 146' facing the slot 143 and a respective operating end 147, 147' accessible from outside by the operator so that the latter may vary one and/or both the end stroke positions.

In particular, the adjusting screws 145, 145' may act along a respective axis Z", Z'" substantially transversely to the axis Y' and preferably perpendicular to the axis Y'. Possibly, such axis Z", Z'" may be substantially coincident.

Suitably, the plate-shaped body 110, similar to the through holes 114, 114', may comprise passing through holes 118, 118' for the adjusting screws 145, 145' which may thus have an axis which coincides with, respectively, the axis Z" and the axis Z'".

From the above description, it appears evident that the hinge according to the invention fulfils the intended objects.

The invention is susceptible of numerous modifications and variations, all falling within the annexed claims. All the details may be replaced with other technically equivalent elements, and the materials may be different according to requirements, without departing from the scope of the invention defined by the annexed claims.
