Detailed Description

With reference to the figures, a control unit 1 will be described herein, which will be particularly suitable for controlling the flow of a working fluid, preferably an incompressible working fluid, such as oil.

The control unit 1 may be used for any purpose, for example it may be used as a single-sided retarder, as shown in 59-60B, or as a double-sided retarder, as shown in fig. 61-64B.

The control unit 1 can also be used in any device. For example, the decelerator shown in fig. 59-64B may be used with a machine tool or a slidable door.

In particular, the control unit 1 may be used to close or control the hinge device 100, as shown in fig. 5 to 8, 15 to 28B, 33 to 41, 47 to 51, 56 to 58 and 65 to 69B.

It is apparent that reference to one or more of the drawings in relation to particular embodiments of the invention is to be regarded as illustrative and non-limiting examples of the invention. The same embodiments may be shown in other drawings but are not specifically mentioned.

Basically, the control unit 1 can consist of a main body 10 into which two or more guide rods 20', 20 "are slidably inserted.

Although reference will be made hereinafter to a control unit 1 having two guide rods 20', 20", it is clear that the control unit 1 may also comprise more than two guide rods without departing from the scope of protection of the appended claims. Obviously, a control unit 1 comprising more than two guide rods will thus be configured.

The invention may comprise various components and/or similar or identical elements. Unless otherwise specified, single reference numerals will be used to designate similar or identical parts and/or elements, it being apparent that the technical features described are common to all similar or identical parts and/or elements.

The body 10 may comprise two working chambers 11 and 12 arranged side by side and defining respective axes Y' and Y ", which may preferably be substantially parallel and substantially coincident, as shown in the embodiment of fig. 63-64B, or substantially perpendicular, as shown in the embodiment of fig. 59-60B and 61-62B.

Such axes Y 'and Y "may also define the sliding axes of the two guide rods 20', 20". The working chambers 11, 12 may contain a working fluid which will flow therein under the thrust of the guide rods 20', 20 ".

Each working chamber 11, 12 may comprise a respective end opening 13', 13 "and 14', 14", which may preferably be arranged along axes Y ' and Y ".

Two guide rods 20', 20 "can be inserted through the openings 13', 14' into the working chambers 11, 12 so that the ends 21', 22' are inside the working chambers 11, 12 and the opposite ends 21", 22 "are outside said working chambers.

On the other hand, the openings 13", 14" may be fluidly connected to each other by means of a conduit 15, which may preferably be substantially perpendicular to the axes Y' and Y ", but also parallel to only one of said axes, as shown in the embodiment of fig. 61-62B.

The geometries and relative positions of the components shown above should not be considered limiting, but merely as illustrations of the invention. The geometry and relative position of the components may be of any type without departing from the scope of protection of the appended claims.

Due to the above characteristics, sliding of the guide 20 'along the axis Y' from the opening 13 'towards the opening 13 "will correspond to sliding of the guide 20" along the axis Y "in the opposite direction from the opening 14" towards the opening 14', and vice versa.

The flow of working fluid through the fluid connection line defined by openings 13", 14" and conduit 15 will in fact ensure that sliding of guide bar 20 'along axis Y' from distal position (e.g. shown in fig. 3A) of tip 21 'from opening 13' towards one proximal position (e.g. shown in fig. 3B) thereof will correspond to sliding of guide bar 20 "along axis 20" in the opposite direction from proximal position (e.g. shown in fig. 3A) of tip 22 'from opening 14' towards one proximal position (e.g. shown in fig. 3B) thereof and vice versa.

Basically, the working fluid will transmit the thrust exerted from the outside on one of the two guides 20', 20 "towards the inside of the body 10 to the other guide, which will be pushed from the inside towards the outside.

In a preferred, but not exclusive, embodiment, the control unit 1 may comprise one or more elements 40 for regulating the flow of working fluid between the working chambers 11, 12.

Although reference will be made hereinafter to a single adjustment element 40, it is clear that the control unit 1 may also comprise more than one adjustment element without departing from the scope of protection of the appended claims. Obviously, a control unit 1 comprising more than one adjustment element will thus be configured.

Suitably, the adjustment element 40 may be at least partially inserted into the fluid connection line defined by the openings 13", 14" and the duct 15 to interact with at least one passage section thereof, thus adjusting the flow of the working fluid.

In a preferred but not exclusive embodiment, such as shown in fig. 1 to 8, the adjustment element 40 may be a baffle element, such as a pin having a diameter D40, movable between two upper and lower passage sections 15 "and 15 'of the duct 15, having diameters D15" and D15', respectively.

Suitably, the diameter D40 is slightly smaller than the diameter D15', for example a few tenths of a millimeter, and the diameter D15' is slightly smaller than the diameter D15", for example still a few tenths of a millimeter.

Due to the above configuration, when the pintle 40 is in the lower passage section 15', the flow rate of the working fluid flowing through the gap between the pintle and the lower passage section is less than the flow rate of the working fluid flowing through the gap between the pintle 40 and the upper passage section 15 ".

Alternate sliding of the pivot 40 between the two upper passage sections 15 "and the lower passage section 15 'may occur due to the oil pressure imparted by the movement of the guide rods 20', 20".

In a further preferred but not exclusive embodiment, such as shown in fig. 11 to 64B, the adjustment element 40 may comprise a screw element 41 which engages in the nut screw 17 for widening/narrowing the passage section 15' "of the duct 15.

It is also possible to provide a plug element 42 which is resiliently forced against the end 41 "of the screw element 41 by means of a spring 43, which screw element furthermore may have an opposite hollow end 41' which can be controlled from the outside by an operator. It is clear that the plug element 42 can also be simply slid without the spring 43, without departing from the scope of protection of the appended claims.

Suitably, the passage section 15' "of the conduit 15 may have a substantially frustoconical shape, the same applies to the distal end 41" of the screw element 41. Preferably, the passage section 15' "may be calibrated.

An access opening 44 "may be provided at the end 41" that may be placed in fluid communication with the opening 13 "and may be selectively closed by the plug element 42.

Further, an access opening 44' may be provided at the end 41' that may be placed in fluid communication with the opening 14 '.

Furthermore, the screw element 41 may comprise an inner conduit 45 extending between the passage openings 44', 44 "for placing said passage openings in fluid communication with each other.

Suitably, the plug element 42 may have a substantially mushroom-like shape with an enlarged tip 42' at the tip 44 "and a guide rod 42" slidably inserted into the inner channel 45 of the screw element 41.

The spring 43 may be sized appropriately such that when the guide rod 20 "is slid from a distal position, such as shown in fig. 13A, to a proximal position, such as shown in fig. 14A, the plug element 42 opens, evacuating the passage opening 44" and allowing a controlled flow of working fluid through the gap between the inner conduit 45 of the plug element 42 and the guide rod 42".

On the reverse path, however, plug element 42 will close, thereby inserting passageway opening 44 "and forcing the working fluid to controllably flow through passageway section 15'".

Thus, basically, the spring 43-plug element 42 assembly acts as a one-way valve member for controlling the flow of the working fluid.

The flow of working fluid through the conduit 15 will always be controlled in both directions. The difference in diameter between the inner conduit 45 and the guide rod 42 "of the plug element 42 will in fact control the flow of the working fluid in one direction, while the size of the passage section 15'" will control the flow of the working fluid in the opposite direction.

In order to protect the control unit 1 from a possible sudden pressure increase therein, an overpressure valve element 50 in the conduit 18 fluidly connected to the conduit 15 may be provided.

The overpressure valve element 50 may comprise a spring 51 and a shutter 52, for example a ball shutter, which is elastically forced against a seat obtained in the duct 18. The spring 51 and the flap 52 may be held in an operative position by a grub screw 53.

Suitably, the spring 51 may be sized so that the flap 52 opens exclusively when the pressure inside the working chamber 11, 12 or in the duct 15 exceeds a predetermined threshold value calculated for the damage of the control unit 1.

Advantageously, the control unit 1 may comprise an elastic resistant member, such as one or more helical springs 30.

The one or more springs 30 may be a push spring or a return spring depending on the function of the device in which the control unit 1 is to be inserted.

Advantageously, each spring 30 can be inserted coaxially onto the respective guide rod 20', 20 "and between the abutment surface 16 of the body 10 and the abutment surface 23 of such springs 20', 20". Alternatively, the spring 30 may be disposed inside the guide rod, as shown in fig. 59-60B.

Suitably, the one or more springs 30 may act exclusively on one of the guide rods, for example guide rod 20", while the other guide rod, for example guide rod 20', may slide freely along the respective axis Y' without elastic resistant members.

For this purpose, in the case of a control unit 1 comprising two springs 30, for example in the embodiment shown for example in fig. 29, 43 and 52, a docking element 31 may be provided, which is fixed to a guide bar, for example guide bar 20, acted upon by the springs 30.

The abutment element 31 may comprise an abutment surface 23 for the spring 30 and may also comprise a through seat 32 for the guide rod 20'. In this way, the guide rod can slide freely along the axis Y' without elastic resistant members.

Advantageously, as better shown below, the docking element 31 may comprise a cam follower member 25", while the guide rod 20 'may comprise or be integrally engaged with the cam follower member 25'.

In view of the above, the action of the one or more springs on the guide bar 20 "will be independent of the action for controlling the fluid flow applied by the control unit 1 on the two guide bars 20', 20".

Thus, due to the functional independence between the springs and the guide rods, even in case of sudden pressure externally applied to one of the guide rods, the other guide rod will always be controlled and the guide rod acted upon by the springs will always return to the maximum distal position.

In a preferred but not exclusive embodiment, the control unit 1 may be particularly adapted to control the flow of working fluid in the hydraulic hinge device 100.

The hydraulic hinge device may be particularly suitable for controlled rotational movement of a closure element P, such as a door, a door leaf or the like, relative to a stationary support structure S, such as a floor, a frame or the like.

Although reference will be made below to the door P and the floor or frame S depending on the various embodiments of the hinge device 100, it is clear that said hinge device can be connected with any closing element and any stationary support structure without departing from the scope of protection of the appended claims.

The control unit 1 in the hinge device 100 can hydraulically control the movement of the door P between a closed position, as shown for example in fig. 8, 18A, 31A and 49, and an open position, as shown for example in fig. 7, 20A, 32A and 50.

Depending on the configuration, the hinge device 100 may be a closing hinge, such as shown in fig. 5A or 15, or a hydraulically controlled hinge, such as shown in fig. 6, 23, 65-69B.

In the former case, the hinge device 100 may contain one or more thrust springs 30, while in the latter case the hinge device 100 may contain a return spring, which preferably may not have a spring.

In use, two or more hinge devices 100, such as two closure hinges or one closure hinge and one hydraulic control hinge, or the closure and control hinge devices 100 and hinges may be mounted on the door P without particular limitation.

By way of non-limiting example, one or more hydraulically controlled hinge devices 100 may be mounted on a fold glass table TP, as shown in fig. 28A and 28B.

In a preferred, but not exclusive, embodiment, such as shown in fig. 5A to 10C, the hinge device 100 may be a flat hinge particularly suited for hidden insertion into a tubular frame of a refrigerator door.

In yet another preferred, but not exclusive, embodiment, such as shown in fig. 15 through 27 and 65 through 69B, the hinge apparatus 100 may be a side-to-side flexible hinge for a frameless glass door.

In a further preferred but not exclusive embodiment, as shown for example in fig. 33 to 41, the hinge device 100 may be a hinge for an inner door that can be tilted to make it laterally flexible, known per se, to be anchored to the floor S by means of the bushing B.

In yet another preferred but not exclusive embodiment, such as shown in fig. 47 to 51, the hinge device 100 may be a left and right flexible hinge for a pivotally mounted frameless glass door to anchor to the floor S.

In a further preferred but not exclusive embodiment, as shown for example in fig. 56 to 58, the hinge device 100 can be a left and right flexible recessed door closure for an interior door known per se, to be anchored to the frame S of the door by means of a pivot arm a.

Advantageously, according to the figures, the hinge device 100 may generally comprise a hinge body 110, which may be integrally anchored to the door P or to the stationary support structure S, depending on the embodiment. For example, in the preferred but non-exclusive embodiment shown in fig. 15 to 27, the hinge body 110 may be anchored to the frame S, while in the preferred but non-exclusive embodiment shown in fig. 47 to 51, the hinge body 110 may be anchored to the door P.

As better shown below, the hinge body 110 may have various configurations depending on the embodiment.

In the embodiment shown in fig. 1 to 58, the control unit 1 can be inserted in a removable manner into the compartment 112 to define a hydraulic section in which the ends 21", 22" of the guide rods 20', 20 "protrude from the body 10 so as to be held in the dry section 113 of the compartment 112 in which they will interact with the pivot 200.

In such embodiments, the hinge body 110 may comprise or consist of a housing 111, possibly of two or more half-housings 111', 111", such as shown in the preferred but not exclusive embodiment shown in fig. 47 to 51. The housing 111 may internally contain at least one compartment 112 into which the control unit 1 and the pivot 200 may be inserted.

On the other hand, as shown for example in the embodiments of fig. 65 to 69B, the control unit 1 may be integrated in the compartment 112 to define the aforementioned hydraulic section. In other words, the control unit 1 can be obtained in the hinge body 110 such that the hinge body contains the control unit.

The pivot 200 may define an axis X that will also act as a mutual axis of rotation between the pivot 200 and the hinge body 110.

The pivot 200 may have one or more portions 201 for coupling to the door P or stationary support structure S and first 210 and second 215 cam members.

The first and second cam members may be arranged side by side or in superposition with each other and they may have this configuration to selectively and alternately interact with the guide bars 20 "and 20', and preferably have corresponding first and second cam follower members 25' and 25" integrally coupled with the first and second cam members, respectively, as better explained below.

In particular, the first and second cam follower members 25', 25 "may be obtained as a single piece with the first and second guide bars 20', 20" to define respective opposite ends 22', 22", as shown in the embodiments of fig. 1-10C or fig. 65-69B, or they may be integrally coupled with the first and second guide bars, as shown in the embodiments of fig. 11-58.

This will facilitate the reciprocating movement of the guide rods 20', 20", such that a sliding movement of the guide rods 20' from the opening 13' towards the opening 13", i.e. from the distal position towards the proximal position, corresponds to a sliding movement of the guide rods 20 "from the opening 14" towards the opening 14', i.e. from the distal position towards the distal position, and vice versa, a sliding movement of the guide rods 20 "from the opening 14' towards the opening 14", i.e. from the distal position towards the proximal position, corresponds to a sliding movement of the guide rods 20' from the opening 13 "towards the opening 13', i.e. from the distal position towards the distal position, of the distal end 21".

As indicated above, during such passage, the working fluid will hydraulically attenuate the door closing and/or opening movement.

Although reference will be made below to a hinge device 100 that automatically closes a door P and hydraulically dampens its closing and opening movements, it is clear that the hinge device 100 can solely hydraulically dampens the closing and opening movements of the door P, such as shown in the embodiments of fig. 6 or 23, 65-69B, without departing from the scope of the appended claims.

The pivot 200 and the control unit 1 may be configured such that the distal and proximal positions of the guide bars 20", 20 'respectively correspond to the closed position of the door P, and the proximal and distal positions of the guide bars 20", 20' respectively correspond to the open position of the door P.

The cam members 210, 215 may be suitably configured for this purpose. In particular, depending on the embodiment of the hinge device 100 and the relative pivot 200, the cam members 210, 215 may define respective axes or planes that are substantially perpendicular to each other.

In any event, the cam members 210, 215 and the guide rods 20", 20' can interact and rotate with each other about the axis X between a door closed position and a door open position in which the guide rods 20", 20' can take the positions described above, sliding along the respective axes Y ", Y '. It is apparent that depending on the embodiment, the one of the cam members 210, 215 and the guide rods 20", 20' will rotate and the other will be stationary.

In particular, when opening the door P, the cam member 210 may push the guide bar 20 "to slide along the axis Y" from a distal position to a proximal position of its tip 22 ". At the same time, the oil present in the chambers 11, 12 will push the guide bar 20 'to slide along Y' from its proximal position at the end 21 "to the distal position. During this movement, the cam member 215 will rotate relative to the guide rod 20' to allow the aforementioned sliding, and the one or more springs 30, if present, will compress from the maximum extended position to the maximum compressed position.

Suitably, the cam member 215 and the distal end 21 "of the guide rod 20' may be spaced apart from each other and not in contact during this movement.

The pressure inside the circuit will bring the plug element 42 to open or bring the pin 40 in the portion 15 "of the pipe 15 to a larger diameter to allow oil to flow through the pipe 15.

In embodiments where the spring 43-plug element 42 assembly is present, as indicated above, such passage would occur through a tubular gap between the inner conduit 45 and the guide rod 42 "of the plug element 42.

Thus, this tubular gap will define a maximum opening force acting on the door P, even in case of sudden stress, for example due to a gust or an careless user. Indeed, even in this case, the door will always be controlled and protected from undesired impacts and possible damages.

Conversely, when closing the door P, the one or more springs 30, if present, may facilitate movement of the guide bar 20 "along the axis Y" from a proximal position to a distal position of the tip 22 "thereof and rotation of the door P toward the closed position. At the same time, cam member 215 will push guide bar 20 'to slide along Y' from its distal position at tip 21 "to its proximal position.

The pressure inside the circuit will bring the plug element 42 to close or bring the pin 40 in the portion 15' of the duct 15 to a smaller diameter, allowing the oil to act to hydraulically attenuate the closing movement of the door P, as described above.

It is apparent that in embodiments in which the hinge device 100 is spring-less, the pushing force may be applied by an external force, such as an external closing hinge or gravity, and the hinge device 100 will essentially act as a hydraulic brake to hydraulically attenuate the closing movement of the door P.

In this way, the movement of the door is always controlled to open and close, even in the event of sudden forces acting on the door P, such as a gust of wind or the thrust of an careless user. On the other hand, if such a pushing force poses a risk to the whole of the hinge device 100, the overpressure valve element 50 will open, thereby protecting the hinge device.

When the door is closed, the one or more springs 30, if present, will act on the cam follower member 25", which in turn will act on the cam member 210 to move the pivot 200 and the door P. This movement is independent of the hydraulic movement of the guide rods 20', 20 ".

In particular, the spring 30-cam follower 25 "-cam 210 assembly will be independent of movement of the guide rod 20". In fact, the guide rod will be pushed to slide along the axis Y "solely by the action of the other guide rod 20', which in turn will be pushed by the cam 215 acting on the cam follower 25'.

Such independent movement, together with the particular configuration of the cam follower 25', will allow to obtain a closing mechanical snap, as better shown below.

The hinge device 100 may advantageously be substantially planar. In particular, the axes Y', Y″ may define a plane pi substantially perpendicular to the axis X, as shown in the embodiments of FIGS. 5A-10C and 33-42, or a plane parallel to the axis, as shown in the embodiments of FIGS. 15-27, 48-51, 56-58 and 65-69B.

In the latter embodiment, the first and second cam members 215, 210 and the first and second cam follower members 25', 25 "may be superimposed on each other along a plane pi defined by axes Y', Y".

In particular, the cam member 210 may comprise or consist of a compartment having a planar surface 211 that is substantially perpendicular and parallel to the plane pi in the position for closing and opening the door P, respectively, as shown for example in fig. 18C and 20C, respectively.

On the other hand, the cam follower member 25 "may comprise or consist of a flat face 260, which is substantially perpendicular to the plane pi, both in the position for closing the door P and in the position for opening said door, for example still shown in fig. 18C, 20C and 69A, respectively.

Furthermore, the cam member 215 may comprise or consist of a compartment having a pair of opposite flat walls 216, substantially parallel and perpendicular to the plane pi in the position for closing and opening the door P, respectively, as shown for example in fig. 18B, 20B and 69B, respectively.

An end portion 217 designed to contact the cam follower member 25' in a closed position, such as shown in fig. 18B, and to be spaced apart from and not in contact with the cam follower member in an open position, such as shown in fig. 20B, may be disposed between the two walls 216. More precisely, the contact area 217 'of the end portion 217, which may be arranged in a central position with respect to the two flat and conical surfaces 217 "and 217'", may be substantially flat and perpendicular to the wall 216.

On the other hand, the cam follower member 25 'may comprise or consist of a flat face 26' which is substantially perpendicular to the plane pi both in the position for closing the door P and in the position for opening said door, for example as still shown in fig. 18B and 20B, respectively.

This flat face 26 'may be positioned in a central position with respect to the two conical flat surfaces 26", 26'" and may be in contact with the cam member 215 to define a stop position at 0 ° and 90 °.

More precisely, the flat surface 26 'may be in contact with the contact area 217' of the end portion 217 in a closed position, for example as shown in fig. 18B, and with one of the walls 216 in an open position, for example as shown in fig. 20B.

This will allow not only to obtain a stable stop position in both the closed and open position, but also to obtain a mechanical snap of the door P towards the closed position.

Starting from the open position shown for example in fig. 20B, the cam member 215 initially in contact with one of the walls 216 will actually rotate about the axis X, pushing on the cam follower member 25'. Due to this rotation, the flat surface 26' may first contact one of the surfaces 217 "or 217 '" and then contact the contact area 217' of the end portion 217, depending on the opening direction.

After passing from one of the surfaces 217 "or 217 '" to the contact region 217', the planar surface 26' will no longer be in contact with the surface but in point contact, as shown in fig. 20D.

Thus, the cam member 215 will experience a sudden and uncontrolled tilting about the point of contact with the cam follower member 25' until the planar surface 26' and the contact region 217' will not contact each other to define the closed stop position. This results in a mechanical snap of the hinge device 100 towards the closed position, due to the fact that the thrust of the spring 30 is continuous and independent of the hydraulic control.

Properly configuring the profile of cam member 215 and cam follower member 25' will allow the point at which such snapping occurs to be predetermined. On the other hand, the force of the buckle will be determined by the force of the spring 30.

It will also be apparent that configuring the cam follower members 25 'or the cam members 215 such that they are free of the flat surfaces 26' will allow the hinge device to eliminate the need for a snap.

In the embodiment of fig. 5A-10C and 33-42, the cam members 215, 210 and cam follower members 25', 25 "may lie in a plane substantially parallel or coincident with a plane pi identified by axes Y', Y".

Suitably, the cam members 215, 210 may extend perpendicularly from the first axis X to contact the first and second cam follower members 25', 25 "and move the guide rods 20', 20" as described above.

In particular, cam members 215, 210 may have surfaces 26, 26 "and 260 designed to interact with surfaces 217 and 211 of cam follower members 25', 25".

Similar to above, in the vicinity of the closed position, cam member 215 will tilt about the point of contact between surfaces 26 and 26 "until surface 26' will not contact surface 217, defining a closed stop position.

It is clear that the profiles of the cams and cam followers of the embodiments are shown herein by way of example only, and they may be configured depending on the motion to be imparted to the opening or closing of the door P.

With particular reference to the embodiment of fig. 33-38, the block 31 may include a cam member 25", and the cam follower 25 'may be removably coupled to the guide rod 20'. This simplifies the installation of the hinge to a maximum extent.

In this embodiment, the pivot 200 may be configured to impinge on the housing 111 to open and close, as shown in fig. 35 and 37. For closing, this allows to give a preload to the door P which pushes against the opposite door leaf. Subsequently, for opening, this solution acts as a system for preventing the door P from disengaging the hinge, thus preventing it from striking any obstacle. For this purpose, the cam followers 25', 25″ can each be provided with a system for ejecting the cams 210, 215.

Instead of cam and cam follower members, in a preferred but non-exclusive embodiment such as shown in fig. 39-40B, pivot 200 may have a pinion member 220 that readily interacts with a corresponding rack and pinion member 27', 27 "integrally coupled with guide rods 20', 20", respectively. The rack and pinion member 27 "may be contained in a block 31 which in turn may be inserted onto the guide bar 20" by means of a pin. On the other hand, the rack and pinion member 27 'may be removably inserted into the guide bar 20' which may freely slide through the opening 32.

Such an embodiment allows maximum control of the door P, which will always be closed from any open position.

The hinge device 100 is extremely easy to install if the control unit 1 with the cam follower member and the pivot 200, which is pre-assembled as a whole as a package, is essentially inserted into the compartment 112 and then the housing 111 is closed using the closing element. A finished cap may be provided.

Advantageously, the adjustment element 40 may be accessible even with the hinge device installed, possibly with the removal of the finished cover.

In the embodiments of fig. 15-27, 33-38, 39-40B, 56-58 and 65-69B, the adjustment element 40 may be practically accessible through the opening 160, whereas in the embodiments of fig. 48-51 the adjustment element 40 may be accessible by removing the cover 161.

With particular reference to the embodiment of fig. 15-27, the housing 111 may have sliding guides 125', 125 "into which the cam follower members 25', 25" are slidably inserted. This will make the mounting of the hinge very easy and make the movement particularly smooth.

Still referring to this embodiment, after inserting the pivot 200 into the housing 111 and the cam follower members 25', 25 "into the guides 125', 125", it would be sufficient to screw the control unit 1 to the housing 111 using the screws 130 through the body 10.

At this time, it is sufficient to screw the aforementioned assembly to the fixing plate 140 by means of the screw 141 in order to complete the installation. This type of mounting makes such hinge devices particularly versatile, provided that the assembly can be mounted on various types of plates 140.

The screw 130 may pass through the fixed plate 140 such that, once in the operating position, its head rests against the plate 140, so that said plate carries the weight of the plate P.

In the embodiment of fig. 65-69B, where the control unit 1 is integrated in the hinge body 110 to define means for hydraulically controlling the flow of working fluid, this embodiment may eliminate the need for screws 130, however it may comprise pins 131 through the plate 140 to carry the weight of the door P.

Suitably, this embodiment may implement an adjustment element similar to the configuration in fig. 68, comprising an adjustment screw 41, a plug element 42 and a spring 43, or just an adjustment screw 41.

Further, this embodiment may provide a completion cover 162.

From the foregoing, it will be apparent that the present invention achieves the intended aim.

The invention is susceptible of numerous modifications and variations, all of which are within the scope of protection of the appended claims. All the details may be replaced with other technically equivalent elements and the materials may be different, as required, without departing from the scope of protection defined by the attached claims.
