Detailed description of some preferred embodiments

With reference to the above-mentioned figures, the hinge device 1 is particularly useful for the rotatably moving and/or controlling of at least one closing element D, such as a door, a shutter, a gate or the like, that may be anchored to a stationary support structure W, such as a wall and/or a door or window frame and/or a support pillar and/or the floor.

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

Preferably, the closing element D may be a glass shutter or a glass door.

It is understood that depending on the configuration, as better explained later, the hinge 1 may allow the automatically opening and/or closing of the closing element D and/or the control during the opening and/or closing of the same closing element D. Possibly, the control may be performed by hydraulic damping means.

The hinge 1 may thus comprise a fixed element 10 which may be anchored to one of the wall W and the closing element D and at least one movable element 20 that may be anchored to the other of the wall W and the closing element D.

In particular, as schematically illustrated in Fig. 1, the fixed element 10 may be coupled to the wall W, for example by the base 3, while the movable element 20 may be coupled to the closing element D, for example by anchoring means 4.

Suitably, as better explained later, the movable element 20 and the fixed element 10 may be rotatably coupled each other to reciprocally rotate around a longitudinal axis X between an open position and a closed position, i.e. so that the reciprocally rotation of the same movable element 20 and fixed element 10 corresponds to the rotation of the closing element D between the closed position (Fig. 2) and the open position (Fig. 3).

One of the movable element 20 and the fixed element 10, preferably the former may comprise an elongated hinge body 21 defining an axis Z while the other of the movable element 20 and the fixed element 10, preferably the latter may comprise at least one pivot 11 defining the axis X which may be substantially perpendicular to the axis Z.

In particular, the hinge body 21 may comprise at least one working chamber 13 for the pivot 11 substantially coaxial to the axis X and a working chamber 23 defining an axis X'. More specifically, the latter working chamber 23 may include at least one slider 30 slidable along the axis X' between a first end stroke position corresponding to one of the open and closed positions of the closing element D and a second end stroke position corresponding to the other of the open and closed positions of the closing element D.

Suitably, the pivot 11 and the slider 30 may be reciprocally configured so that the rotation of the movable element 20 between the open and closed position corresponds to the sliding of the slider 30 between the first and the second end stroke positions.

The hinge 1 may thus comprise cam means 40 and cam follower means 50 reciprocally engaged so that the rotation of the former corresponds to the translation of the latter.

For example, the pivot 11 may include cam means 40 rotating around the axis X, while the cam follower means 50 may interact with the slider 30 so as the rotation of the movable element 20 around the axis X corresponds to the sliding of the slider 30 along the axis X'.

According to a particular embodiment, the axis X' of the working chamber 23 may be substantially parallel to the axis X of the pivot 11 and spaced apart from the latter. In other words, as particularly shown in Fig. 3, the chamber 13 and the chamber 23 may be substantially parallel to each other.

Thanks to this feature, the hinge 1 may have low bulkiness. More in detail, the particular configuration of the working chamber 23 may allow to manufacture a hinge body 21 having a minimum length along the axis Z.

Possibly, in order to improve the aesthetic appeal of the hinge 1, the hinge body 21 may have a decreasing thickness along the axis Z starting from the working chamber 23 towards the opposite end.

As particularly shown in Figs. 6, 8A and 8B, the cam means 40 may comprise at least one annular element 41 having a tubular wall 41' configured so that the outer annular surface 42 thereof is substantially coaxial with an axis Y while the annular inner surface 43 is substantially coaxial to an axis Y' transverse to the axis Y. In particular, the annular element 41 may be configured so that once inserted on the pivot 12, the axis Y' may coincide with the axis X of the pivot 12, while the axis Y may be inclined with respect to the latter.

The pivot 11 and the annular element 41 may be joined each other, for example as shown in the annexed figures the latter may be coupled by a pin 45 passing through the tubular wall 41'.

Suitably, the latter may include a passing through hole 46 inclined with respect to the axis Y so that the pin 45, once inserted in the passing through hole 46 is substantially perpendicular to the axis X.

On the other hand, the cam follower means 50 may comprise at least one annular element 51 which may be coaxially coupled with the annular element 41 so that the rotation of the movable element 20 around the axis X promotes the reciprocal rotation of the annular elements 41, 51 around the axis Y.

Once coupled the annular elements 41, 51, the annular element 51 may thus have a substantially cylindrical tubular wall 51' having an inner surface 53 reciprocally facing the outer surface 42 of the annular element 41 and preferably in contact therewith.

Advantageously, the tubular wall 51' of the annular element 51 may comprise a groove or an hole 54 to allow the insertion of the pin 45 in the annular element 41 once the annular element 51 and the annular element 41 are coupled.

Suitably, the annular element 41 may comprise an annular projection 44, while the tubular wall 51' of the annular element 51 may have an inner diameter less than the annular projection 44 so that the latter may act as abutment for the tubular wall 51' during the coupling and may guide the same annular element 51 during the reciprocal rotation.

For example, as shown in the annexed figures and better described later, during the rotation of the hinge body 21 around the axis X, the annular element 41 may remain stationary integrally with the pivot 12, while the annular element 51 may rotate around the axis Y. In this way, the same annular element 51 may move along the axis X.

Suitably, the follower cam means 50 may comprise means 60 for reciprocally connecting the annular element 51 and the slider 30 so that the sliding of the former along the axis X corresponds to the axial sliding of the latter along the axis X'.

In particular, the connecting means 60 may have an end 61 operatively connected with the slider 30 to slide along the axis X' between a lowered position (Fig. 2) and a raised position (Fig. 3).

More particularly, the connecting means 60 may comprise a rotating joint 62 operatively connected with the slider 30 and a rod 65 for the connection with the annular element 51.

Possibly, the rod 65 may be integral with the annular element 51, preferably may be monolithic as shown in Fig. 7, and for example the rod 65 may be consisting of a tubular element extending from the outer surface 52 of the tubular wall 51' of the annular element 51.

The rotating joint 62 may comprise a cylindrical element 63 perpendicularly coupled with the connecting rod 65 to move between the raised and lowered positions.

The cylindrical element 63 may comprise a seat 64, for example a passing through hole, for at least partially housing the rod 65.

On the other hand, the slider 30 may comprise a portion 31 having a cylindrical surface 31' operatively in contact with the cylindrical element 63.

In this way, after the rotation of the hinge body 21, the connecting means 60 may rotate around the axis X thereby promoting the rotation of the annular element 51. Upon the rotation of the latter with respect to the annular element 41, the annular element 51 may axially slide thereby promoting the axial slide of the connecting means 60 and therefore the slide of the slider 30 from the first end stroke position to the second end stroke position.

According to an aspect of the invention, the working chamber 23 may include elastic counteracting means 70 acting on the slider 30 to promote the slide thereof from the second end stroke position to the first end stroke position.

For example, the elastic counteracting means 70 may comprise at least one spiral spring 71, while the slider 30 may comprise a substantially tubular portion 32 defining a seat for housing at least one end portion 71' of the coil spring 71.

In other words, the spring 71 may remain interposed between the tubular portion 32 of the slider 30 and the bottom wall 24 of the working chamber 23.

According to a particular aspect of the invention, the spring 71 may be a closing spring so that the hinge 1 is a hinge for the automatic closing of the closing element D.

Although not shown in the annexed figures, it is understood that the working chamber 23 may comprise braking and/or damping means acting on the slider 30 of a type known per se, which may be of a mechanical and/or hydraulic type.

It is further understood that according to different embodiments not shown in the annexed figures, the chamber 13 and the chamber 23 may be transversal to each other, preferably substantially perpendicular to each other.

According to a particular embodiment, the chamber 13 may comprise means 100 for braking the rotation of the closing element D during the rotation between the open and the closed positions. More particularly, the braking means 100 may act on the pivot 11 to brake the rotating movement of the movable element 20 between the open and closed positions.

Suitably, the braking means 100 may comprise at least one first braking element 110 integral with the pivot 11 which may frictionally engage against at least one second brake element 120 integral with the hinge body 21.

For example, the braking elements 110, 120 may include or consist of at least one respective first and second annular disk-shaped braking elements 111, 121 both inserted in the working chamber 13.

In particular, a plurality of first and second annular disk-shaped elements 111, 121 mutually superimposed may be provided and preferably alternately staked to one another as shown in Fig. 5.

More particularly, the annular disk-shaped elements 111, 121 may all be coaxial to the pivot 12. Suitably, each annular disk-shaped elements 111, 121 may thus include a passing through opening 112, 122 for the pivot 12.

According to a particular aspect of the invention, the first annular elements 111 may be integral with the pivot 12, while the second annular elements 121 may be integral with the hinge body 21.

Thus, during the rotation of the movable element 20 around the axis X, the annular elements 111, 121 may be in reciprocal contact so that the friction between them may brake the reciprocal rotation of the movable element 20 and the fixed element 10.

Suitably, the braking means 100 may comprise pressing means 130 for mutually pushing the braking elements 110, 120, so as to force them in reciprocal contact.

Pressing means 130 may comprise a fixed abutment element 131 and elastic counteracting means 135.

Suitably, as shown in Fig. 2, the braking elements 110, 120 may be interposed between the fixed abutment element 131 and the elastic counteracting means 135 so that the latter forces the first and second annular disk-shaped elements 111, 121 against such fixed abutment element 131.

As particularly shown in FIG. 6, in case of a plurality of alternately annular elements

111, 121 are provided to form a column of annular elements, the latter may be interposed between the fixed abutment element 131 and the elastic counteracting means 135 so that one 111' of the first annular elements is in contact with the elastic means 135, whereas one 121' of the second annular elements is in contact with the abutment element 131.

However, it is understood that any couple of annular elements 111, 121 may abut the elastic means 135 and the abutment element 131.

The latter may comprise, possibly may be consisting of a radial annular appendix of the working chamber 13 which may comprise an abutment surface 131' for the annular element 121'.

Suitably, such annular appendix 131 may thus define an opening 132 for the passing of the pivot 12.

On the other hand, the elastic element 135 may include thrust springs or at least one disc spring 136, preferably a pair of cup springs, which may thus be interposed between the bottom wall 14 of the working chamber 13 and the braking elements 110, 120. For example, as shown in the annexed figures, the disc spring 136 may be abut the annular element 111'.

According to a particular aspect of the invention, the pressing means 130 may be of adjustable type. In particular, the operator may act thereon to vary the friction intensity between the braking elements 110, 120 and thus the intensity of the braking action.

Suitably, the pressing means 130 may thus comprise a partially threaded cylindrical element 138, while the working chamber 13 may comprise a counter-threaded portion 15 with respect to the cylindrical element 138.

The cylindrical element 138 may be interposed between the bottom wall 14 and the braking elements 110, 120, preferably between the bottom wall 14 and the disc spring 136.

In this way, the force exerted on the braking elements 110, 120 may be increased/decreased by the screwing/unscrewing of the cylindrical element 138.

Suitably, the latter may comprise a portion 138' susceptible to be maneuvered by the operator so that the operator may vary the braking action intensity of the braking means 100.

Such portion 138' may remain accessible to the same operator even after the movable element 20 is mounted on the closing element D.

Advantageously, also the cylindrical element 138 may have a passing through opening 139 for the pivot 11 so as to be coaxially placed thereon.

In order to make integral the second annular elements 121 with the hinge body 21, the working chamber 13 may comprise at least one peripheral axial groove 16, while the second annular elements 121 may include at least one radial projection 123. In particular, the latter may be inserted in the peripheral axial groove 16 so as to make reciprocally integral the second annular elements 121 and the hinge body 21.

Preferably, the working chamber 13 may comprise a pair of opposed peripheral axial grooves 16, while the second annular elements 121 may include a pair of radial projections 123 susceptible to be inserted in the respective axial grooves 16. On the other hand, in order to make integral the first annular elements 111 with the pivot 11, the latter may comprise means 140 for the coupling with the former so as to make reciprocally integral the first annular elements 111 and the pivot 11.

In particular, the coupling means 140 may include at least one guide element 141 operatively coupled with the pivot 11 to remain integral therewith.

More in detail, the guide element 141 may have a shaped outer surface 142, while the first annular disk-shaped elements 111 may have an inner surface 113 counter-shaped with respect to the shaped outer surface 142.

On the other hand, the guide element 141 may have an inner surface 143 configured so as to be integrally coupled with the pivot 12.

Suitably, the maximum external diameter of the guide element 141 may be substantially lower or coincident with the diameter of the aperture 122 of the second annular disk-shaped elements 121 so that the guide element 141 and the latter may reciprocally rotate, while the outer surface 114 of the first annular elements 111 may be substantially cylindrical so as not to interact with the grooves 16 of the working chamber 13.

In this way, the second annular disk-shaped elements 121 and the first annular disk- shaped elements 111 may be integral respectively with the hinge body 21 and the pivot 11, so that during rotation of the movable element 20 with respect to the fixed element 10, the first and second disc-shaped annular elements 111, 121 may reciprocally rotate so as to exert a braking action as above described.

According to a particular aspect of the invention, the guide element 141 may be of a unidirectional type so that the same guide element 141 is integral with the pivot 11 only during one of the opening or closing of the closing element D.

In other words, during one of the opening and the closing, i.e. upon the rotation of the hinge body 21, the first annular elements 111 may be integral with the pivot 11 to reciprocally rotate with respect to the second annular elements 121 to exert a braking action, while upon the other of the opening and the closing the first annular elements 111 may rotate integrally with the second annular elements 121 with respect to the pivot 11 so as not to exert a braking action.

Possibly the guide element 141 may include a one-way guide bearing 144 of a known type, including the inner surface 143 and a cylindrical element 145 including the outer surface 142. In particular, the one-way guide bearing 144 and the cylindrical element 145 may be coaxially reciprocally coupled, preferably by interference, and may include a respective aperture 144' 145' for the pivot 11.

During use, as shown in Fig. 4, the one-way guide bearing 144, the cylindrical element 145, the annular disk-shaped elements 111, 121, the disc spring 136 and the cylindrical element 138 may be coaxially inserted on the pivot 11.

Possibly the latter may include an annular projection 17 susceptible to abut the oneway guide bearing 144 once coaxially coupled with pivot 11.

It is understood that the hinge 1 having any configuration of the cam means 40 and the cam follower means 50 and/or the working chamber 23 and the slider 30 may comprise the braking means 140 above described.

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