Description
- The present invention is generally applicable to the technical field of the closing or damping/control hi nges, and particularly relates to a concealed hinge for the contolled rotatable movement of a door, in particular a reinforced door, connected to a tubular support structure which includes a rear counterframe anchored to a wall or a similar support and a front frame anchored to the counterframe.
- As known, the closing or damping hinges generally include a movable member, usually fixed to a door, a shutter or the like, pivoted onto a fixed member, usually fixed to the support frame thereof, or to a wall and/or to the plate.
- More particularly, the fixed member of the concealed hinges for reinforced doors or the like is inserted into a tubular support structure that includes a rear counterframe anchored to a wall or a similar support and a front frame anchored to the counterframe.
- The movable member generally further includes a connecting plate fixable to the door susceptible to extend from the tubular support structure in the open position and to completly retract within the tubular support structure in the closed position.
- Generally, such hinges are merely of the mechanical type, and do not allow any kind of adjustment of the opening angle of the door or in any case no control of the movement of the same door.
- The absence of any control makes such hinges extremely dangerous, since due to the considerable mass of the reinforced door there is the danger of unhinging of the same door or the bending of the tubular support structure to which the hinge is anchored.
- Still due to the considerable mass of the door the hinge further tends to lose the initial position and/or to became misaligned.
- The adjustment of the position of the door is further difficult and complicated. Moreover, in order to do so, at least two operators are needed.
- Another recognized drawback of these hinges is in the high friction between the fixed and movable member, which leads to premature wear and frequent breakages, thus resulting in the need for continuous maintainance.
- From
US5075928 a hinge is known having all the features of the preamble of theindependent claim 1. - An object of the present invention is to overcome at least partly the above mentioned drawbacks, by providing a hinge high functionality, simple construction and low cost.
- Another object of the invention is to provide a hinge which allows controlling the movement of the door upon its opening and/or its closing.
- Another object of the invention is to provide a strong and reliable hinge.
- Another object of the invention is to provide a hinge having extremely small dimensions.
- Another object of the invention is to provide a hinge which ensures the automatic closing of the door from the open door position.
- Another object of the invention is to provide a hinge that can support very heavy doors and shutters.
- Another object of the invention is to provide a hinge that has a minimum number of constituent parts.
- Another object of the invention is to provide a hinge suitable to maintain the exact closing position during time.
- Another object of the invention is to provide a hinge that is safe.
- Another object of the invention is to provide a hinge that is easy to install.
- Another object of the invention is to provide a hinge that simplifies the operations of maintenance and/or replacement thereof.
- Another object of the invention is to provide a hinge which allows a simple adjustment of the door to which it is connected.
- Another object of the invention is to provide a hinge that is reversible, i.e. to be used straight or upside down without changing its behavior.
- These objects, as well as other which will appear clearer hereafter, are fulfilled by a hinge according to
claim 1. - Essentially, the hinge includes a fixed member and a movable member, the latter being rotatably coupled with the fixed member to rotate between an open position and a closed position about a first longitudinal axis.

- Preferably, the first adjustment means may include a first passing-through opening made at the central projecting portion of the backplate and an actuating member susceptible to interact with the first passing-through opening to adjust the sliding of the mounting bracket along the second axis in response to the operation of the actuating member by a user.
- In a first preferred but not exclusive embodiment, the actuating member may include a plurality of first peripheral shaped cogs, while the passing-through opening of the central projecting portion of the backplate may include a pair of side walls substantially parallel to the first and/or the second axis comprising a plurality of second cogs complementarily engaged with the first cogs.
- On the other hand, alternatively, the actuating member may include an eccentric engaged with the passing-through opening of the central projecting portion of the backplate.
- Preferably, the second adjustment means may include a pair of elongated shaped passing-through slots in correspondence of the third plate-shaped end elements of the mounting bracket, the slots having maximum length equal to the maximum possible offset of the mounting bracket along the third axis. The second adjustment means may further include a pair of second locking screws passing through the first plate of the connecting plate and through the elongated slots of the mounting bracket, the second locking screws being engageable in respective counterthreaded seats in correspondence of the guide elements.
- In a preferred but not exclusive embodiment of the invention, the first central portion and the second end portions of the connecting plate may be monolithic. Moreover, the first and the second plate-shaped portion of the mounting bracket may preferably be monolithic.
- Preferably, one of the second portions of the connecting plate of the hinge may include a curvilinear cam element rotating unitary with the connecting plate about the first axis.
- Suitably, the box-shaped hinge body may further include at least one working chamber defining a fourth axis spaced apart from the first longitudinal axis and substantially parallel thereto.
- The at least one working chamber may include a plunger element slidable along the fourth longitudinal axis and elastic means operatively connected to the plunger element.
- The latter may include a front face facing the curvilinear cam element and interacting therewith so that the rotation of the cam about the first axis corresponds to the sliding of the plunger element along the fourth axis and vice-versa.

- Suitably, the curvilinear cam element may have a generally triangular shape with an operating surface having a predetermined inclination so that upon the opening of the door the plunger element moves from the distal position to the proximal one, respectively from the proximal position to the distal one.
- Preferably, the front face of the plunger element may have a generally rounded shape to come in contact with the substantially flat operating surface of the curvilinear cam element.
- In a preferred but not exclusive embodiment of the invention, the front face of the plunger element may be made of a first metal material that has a hardness greater than the one of the second metal material in which the operative surface of the cam element mat be made, so that the front face of the plunger element is susceptible to made during use a guide channel along the operatve surface of the cam element.
- In a preferred but not exclusive embodiment of the invention, the working chamber may further include a working fluid acting on the plunger element to hydraulically counteract its action.
- The plunger element may separate the working chamber in at least one first and second variable volume compartments fluidically communicating each other and preferably adjacent. The elastic contrast means may be placed in the first compartment so that the at least one first and second compartments have respectively the maximum and minimum volume at the distal position of the plunger element and respectively minimum and maximum volume at the proximal position thereof.
- Suitably, the plunger element may comprise one-way valve means for the control of the passage of the working fluid between the at least one first and second compartments upon the passage of the front face from one of the distal or proximal positions to the other of the proximal or distal positions. A hydraulic circuit may further be provided for the flow of the working fluid between the at least one first and second variable volume compartments upon the passage of the front face from the other of the distal or proximal positions to the one of the distal or proximal positions.
- In a preferred but not exclusive embodiment, the plunger element may include a seat for the valve means fluidically connected with both the first and the second compartment. The valve means may include a control element sliding within the seat along the fourth axis to selectively open/close the fluid communication between the first and the second compartment. The selective opening of the valve means may allow fluid communication between the first and the second compartment. The selective closure of the valve means may prevent fluid communication between the first and the second compartment and may force the passage of the working fluid through the circuit.
- Advantageously, the plunger element may include a tubular element with a front portion placed in the second compartment, a rear portion placed in the first compartment and a side wall facing the side wall of the working chamber. The front and rear portions may be in fluid communication each other and with the seat of the valve means.
- The plunger element may further include a rod with a first end unitary coupled with the front portion of the tubular element and a second end which may include the front face faced to the curvilinear cam element.
- In a preferred but not exclusive embodiment of the invention, regardless of the fact that the hinge is a concealed hinge or not, the hydraulic circuit may be made internally to the box-shaped hinge body externally to the work chamber and may have at least one first inlet/outlet opening in the second compartment and a second and a third inlet/outlet opening both in the first compartment, the first opening being upstream of the second one.
- In a first embodiment, the valve means may be configured to open upon the passage of the front face from the proximal position to the distal one, so as to allow the passage of the working fluid from the second compartment to the first one, and close upon the passage of the front face from the proximal position to the distal one, so as to force the working fluid to pass from the first compartment to the second compartment by entering the hydraulic circuit through the second and third opening and exiting therefrom through the first opening.
- In this embodiment, the third opening may remain fluidically decoupled from the side wall of the tubular element throughout the stroke of the plunger element from the distal position to the proximal one, said second opening remaining fluidically decoupled from the side wall of the tubular element for a first starting part of the stroke of the plunger element and remaining fluidically coupled with the side wall of the tubular element for a second final part of the stroke thereof, so that the door has a first resistance to the movement upon closing/opening for a first angular portion of the rotation thereof about the first axis corresponding to said first starting part the stroke of the plunger element and a second resistance to the movement upon closing/opening of the door for a second angular portion of the rotation thereof about the first axis corresponding to second final part of the stroke.
- Advantageously, the hinge may include first and second means for regulating the cross-sectional flow area of respectively the second and the third openings, so as to allow a user to independently adjust the first and/or the second resistance to the movement upon the closing/opening of the door.
- Suitably, the elastic means may include a restoring spring, so that the hinge is a damping hinge for the control of the rotational motion of the door. It is understood that the term "restoring spring" means a spring whose size and/or configuration is sufficient to move back the plunger element from the proximal position to the distal one, but is not sufficient to automatically close the door once opened.
- In a preferred embodiment, the cam element may be configured in such a manner that upon the opening of the door the plunger element moves from the distal position to the proximal one, the first and second adjustment means being adapted to adjust the first and the second resistance to the movement of the door along the first and the second angular portion upon its opening.
- In another alternative embodiment, the cam element may be configured in such a manner that upon the opening of the door the plunger element moves from the proximal position to the distal one, the first and second adjustment means being adapted to adjust the first and the second resistance to the movement of the door along the first and the second angular portion upon its closure.
- On the other hand, in a second embodiment, the valve means are configured to open upon the passage of said front face from the proximal position to the distal one, so as to allow the passage of the working fluid from the first to the second compartment, and to close upon the passage of said front face from the proximal position to the distal one, so as to force the working fluid to pass from the second compartment to the first compartment by entering in said hydraulic circuit through said first opening and exiting therefrom through said second and third openings.
- In this embodiment, the third opening may remain fluidically decoupled from the side wall of the tubular element throughout the stroke of the plunger element from the proximal position to the distal one, so that the door has a third predetermined opening /closing speed, the second opening remaining fluidically coupled with the side wall of the tubular element for a first starting part of the stroke of the plunger element and remaining fluidically decoupled from the lateral wall of the tubular element for a second final part of the stroke thereof, so as to impart a opening/closing latch action to the door.
- Suitably, the hinge may include third means for the regulation of the cross sectional flow area of the second opening, so as to allow a user to adjust the force by which the door latches toward the opening/closing position, fourth means being further provided for the regulation of the cross sectional flow area of said third opening, so as to allow a user to adjust the opening/closing speed of the door.
- Suitably, the cam element may be configured in such a manner that upon the opening of the door the plunger element moves from the proximal position to the distal one, the elastic means including an actuating spring so that the hinge is a closing hinge, said third and fourth regulating means being susceptible to adjust the latching force of the door toward the closed position and the speed thereof upon its closure.

On the other hand, themovable element 20 includes a connectingplate 21, which can be anchored to the door D, susceptible to extend from the tubular support structure in the open position, shown in FIGa. 4a and 4b, and retract within the same tubular support structure in the closed position, shown inFIGs. 3a and 3b . - The connecting
plate 21 has a substantially "C" shaped, with acentral portion 22 adapted to be connected with the door D by means of the mountingbracket 30 and a pair ofend portions 23, 23' mutually faced to each other and operatively connected with the box-shapedbody 11. - Preferably, the
central portion 22 andend portions 23, 23' may be monolithic to each other, with thecentral portion 22 which consists of a plate-shaped element defining a first plane π substantially parallel to the axis X and theend portions 23, 23' which are constituted by a pair of plate-shaped elements defining respective second plates π', π" substantially parallel to each other and perpendicular to the first plane π. The mountingbracket 30 has a first plate-shapedportion 31 operatively anchored to the door D by suitable screws inserted into theholes 32, first plate-shapedportion 31 being monolithically coupled with a second plate-shapedportion 33, formed by the two end plate-shapedelements 34, 34'. - Preferably, the plate-shaped elements of the
ends 34, 34' may be substantially perpendicular to the first plate-shapedportion 31, and may be operatively connected to thecentral portion 22 of the connectingplate 21 by means of thebackplate 40, whose function will be better explained later. - Once operatively connected, the end plate-shaped
elements 34, 34' will be interposed between the inside of thecentral portion 22 of the connectingplate 21 and thebackplate 40. - In order to allow the coupling with the connecting
plate 21, the box-shapedhinge body 11 includes a pair ofend seats 12, 12' defining the axis X. The box-shapedhinge body 11 includes a longitudinal passing-throughhole 13 defining the axis X adapted to join together the end seats 12, 12'. - As particularly shown in
FIG. 7b , within the passing-throughhole 13 is inserted with minimal clearance ashaft 24 having opposite ends 25, 25' mutually connected with theend portions 23, 23' of the connectingplate 21 by appropriate fastening screw means 26. In this way, theshaft 24 will be unitary movable with the connectingplate 21 between the opening and closing positions. Theend portions 23, 23' of the connectingplate 21 include respective operative surfaces 27, 27' susceptible to remain faced during use to the end seats 12, 12' of the box-shapedhinge body 11. - In correspondence of the latter end seats 12, 12' respective
annular housings 14, 14' are formed adapted to receive respectiveanti-friction elements 15, 15', for example bearings. Theannular housings 14, 14' and therespective bearings 15, 15' are mutually configured so that the operative surfaces 27, 27' of the connectingplate 21 come into contact engage with theanti-friction bearings 15, 15' and remain spaced apart from the box-shapedbody 11, as shown inFIG. 23 . This will allow themovable element 20 to rotate about the axis X with minimum friction, so that thehinge 1 is able to support also very heavy doors D. - More particularly, while the inner diameter D1 of the
annular housings 14, 14' may be substantially equal to the outer diameter D2 of theanti-friction bearings 15, 15', the height h2 of the latter may be slightly higher than the one h1 of the former, in the order of a few tenths of a millimeter. - On the other hand, the
shaft 24 has a height h3 slightly greater than the distance d1 between the upper surfaces of theanti-friction bearings 15, 15', so that when one of the operating surfaces of the connectingplate 21, for example theupper one 27, come in contact engage with the respective anti-friction bearing 15, the other operating surface 27' remains spaced apart from the respective anti-friction bearing 15'. - Thanks to this feature, the antifriction effect is maximized. Moreover, the
hinge 1 is reversible, i.e. it can be used in both directions, that is the one shown in the figures or upside down, without changing its behavior. - The
shaft 24 may further have a diameter DS substantially coincident with the diameter DH of the passing-throughhole 13. The difference between the two diameters DH and DS may be minimal, in the order of a few hundredths of a millimeter. Preferably, theshaft 24 may have a cylindrical shape and be made of metallic material, e.g. steel. - The passing-through
hole 13 may further have a substantially cylindrical shape with a diameter DH constant throughout its length. In this manner, theshaft 24 has the peripheral wall 24' which is in contact engage with the inner surface 13' of the passing-throughhole 13. - Thanks to this feature, the
shaft 24 is laterally supported by the inner surface 13' of the passing-throughhole 13 substantially along its entire height h3, less the portions of a few mm projecting therefrom. This prevents any misalignment of theshaft 24 and, consequently, of the closing element D. - In this way, the
hinge 1 can support even very heavy closing elements D without misalignments. - In fact, the
anti-friction bearings 15, 15' support the whole weight of the closure element D through the operative surfaces 27, 27' of the connectingplate 21. - On the other hand, the minimum clearance between the
shaft 24 and the passing-throughhole 13 prevents any misalignment of the closure element D from the original position, usually the vertical one. This maximizes the duration of the hinge over time, and also minimizes the need of maintenance therefor. - In order to allow the stop of the hinge in the desired position, at least one of the end portions of the connecting
plate 21, for example the lower one 23', may include a projection 28' axially directed towards the inner side of the same connectingplate 21, while thehinge body 11 may include at least one end portion, for example the bottom one 16', which may comprise a respective adjustable stop set screw 17'. - This way, it will be possible for a user to adjust the opening angle of the connecting
plate 21, and then the one of the door D connected thereto. - In fact, the at least one projection 28', that rotates unitary with the connecting
plate 21 around the axis X, abuts against the at least one stop set screw 17', and stops. - Suitably, the at least one stop set screw 17' may include a first end 170' susceptible to selectively interact with the projection 28' and a second end 171' operateable from the outside by a user to adjust the stroke of the same stop set screw 17' along a direction d substantially orthogonal to the first axis X.
- Advantageously, the at least one stop set screw 17' may be screwed into the
hinge body 11 in correspondence of the at least one end portion 16' thereof. Therefore, the user acting on the end 171' screws and unscews the at least one stop set screw 17' from its seat 160'. - In a preferred but not exclusive embodiment, the end portion 16' of the
hinge body 11 may include curvilinear slot 18' defining the path of the projection 28' upon its rotation about the axis X. Appropriately, the curved slot 18' may be concentric with respect to the axis X. - In this way, the projection 28' moves within the curvilinear slot 18' throughout its angular rotation about the axis X.
- Preferably, the passing-through seat 160' of the at least one stop set screw 17' can be made in correspondence of the curvilinear slot 18'.
- In some embodiments, such as the ones shown in FIGs. from 7a to 9b, two blocking
projections 28, 28' may be suitably provided arranged at bothend portions 23, 23' of the connectingplate 21 and adapted to abut against the corresponding stop setscrews 17, 17' which are at bothend portions 16, 16' of thehinge body 11. - In a particularly preferred but not exclusive embodiment, both
end portions 16, 16' of thehinge body 11 may include respectivecurvilinear slots 18, 18'. - Suitably, such as particularly shown in
FIG. 9a , the latter may define means for guiding and centering the lockingprojections 28, 28' upon their rotation about the axis X. - As better explained later, the same
curvilinear slots 18, 18' may further define means for guiding and centering thecurvilinear cam element 60 in the embodiments that include this feature. - Preferably, the plate-shaped
portion 33 of the mountingbracket 30 may be movably mounted on the central plate-shapedelement 22 of the connectingplate 21 to slide along a substantially vertical axis X' parallel to the vertical axis X and along a substantially horizontal axis Z substantially perpendicular to the vertical axis X. - To this end, the
backplate 40 may have an overall height h4 slightly less than the distance d2 between theoperative surfaces 27, 27' of the end plate-shapedelements 23, 23' of the connectingplate 21, so that it can slide vertically internally to the central plate-shapedelement 22 of the connectingplate 21. - The
backplate 40 may have a pair ofend portions 41, 41' and acentral portion 42 outwardly protuding with respect to the latter. - The
central portion 42 of thebackplate 40 may have a height h5 substantially equal to the distance d3 between the plate-shapedelements 34, 34' of the mountingbracket 30 and a thickness S1 slightly greater than the thickness S2, S3 of the latter, so that the mountingbracket 30 has a minimum clearance when sandwiched between thebackplate 40 and the inner side of the central plate-shapedelement 22 of the connectingplate 21. - In this manner, the
upper surface 43 of the central protrudingportion 42 of thebackplate 40 guides the sliding of the mounting bracket along the horizontal axis Z. - On the other hand, a pair of
guide elements 44, 44' may be provided each inserted in arespective opening 45, 45' passing through theend portions 41, 41' of thebackplate 40. - Advantageously, the height h6, h7 of the
guide elements 44, 44' may be less than the height h8, h9 of the passing-throughopenings 45, 45' of thebackplate 40, while their length l1, l2 may be substantially equal to the one l3, l4 of the latter. - This way, the side surfaces 46, 46' of the
guide elements 44, 44' guides the sliding of the mountingbracket 30 along the vertical axis X'. - Advantageously, first means for adjusting the position of the mounting
bracket 30 along the substantially vertical axis X' and second means for adjusting the position of the mountingbracket 30 along the substantially horizontal axis Z may be provided, which may be selectively operateable by a user to allow the independent adjustment of the position of the door D in the vertical and/or the horizontal direction when anchored to the same mountingbracket 30. - In a preferred but not exclusive embodiment, the first means for adjusting the sliding of the door D along the horizontal axis Z may include an
aperture 47 passing through the central protrudingportion 42 of thebackplate 40, an actuatingmember 48 and afirst locking screw 50 passing through the plate-shapedelement 22 of the connectingplate 21 and through the central protrudingportion 42 of thebackplate 40 to complementarily engage with a counterthreaded seat 50' in the actuatingmember 48. - By unscrewing the first locking screw 50 a user can leave free the actuating
member 48 to interact with the passing-throughopening 42 to adjust the sliding of the mountingbracket 30 along the vertical axis X, for example by rotating around its axis by means of a suitable wrench. Once reached the desired position, the user can tighten thefirst screw 50. - In a first embodiment, shown for example in
FIGs. 5a to 5d , the actuatingmember 48 may include a plurality of first peripheral shapedcogs 49 engaged with second countershaped cogs 49' in correspondence of theside walls 47', 47" of the passing-throughopening 47. - In a second alternative embodiment, shown for example in
FIGs. 6a to 6c , the actuatingmember 48 may include an eccentric member 48' engaged with the passing-throughopening 47. - Suitably, the second means for adjusting the sliding of the door D along the vertical axis X' may include a pair of elongated slots shaped 35, 35' passing through the end plate-shaped
elements 34, 34' of the mountingbracket 30 and a pair of second locking screws 51, 52 passing through the plate-shapedelement 22 of the connectingplate 21 and through theelongated slots 35, 35' to engage with respective counterthreaded seats 51', 52' of theguide elements 44, 44'. - By unscrewing the second locking screws 51, 52 a user can leave the end plate-shaped
elements 34, 34' of the mountingbracket 30 and the relative shapedelongated slots 35, 35' free to move horizontally along the axis Z guided by theupper surface 43 of the central protrudingportion 42 of thebackplate 40. Once reached the desired position, the user can tighten the second locking screws 51, 52. - Suitably, the shaped
elongated slots 35, 35' can present maximum length l5, l6 equal to the maximum possible offset of the mountingbracket 30 along the horizontal axis Z. - The
hinge 1 can assume various configurations. For example, it may be purely mechanical, such as the embodiment shown inFIGs. 7a to 9b , or may be mechanical with a closing mechanism of the door from the open position, or may be hydraulic, such as the embodiments shown inFIGs. 10 to 22b . - More particularly, the hydraulic hinge may be a closing hinge, such as the embodiment shown in
FIGs. 10 to 14b , or a hinge for controlling the rotatable motion of the door both upon opening, such as the embodiment shown inFIGs. 15 to 18b , or closing, such as the embodiment shown inFIGs. 19 to 22b . - Therefore, one of the end portions of the connecting
plate 21, for example theupper one 23, may advantageously include a generally triangularcurved cam element 60 rotating unitary with the same connectingplate 21 about the axis X. Thecurved cam element 60 may be attached to itsend portion 23 in a removable or unremovable manner. - In this case, the
cam element 60 may be guided and centered in its rotation around the axis X by thecurvilinear slot 18. - Conveniently, the box-shaped
hinge body 11 may further include a workingchamber 70 with abottom wall 71. The workingchamber 70 may have elongated shape to define a longitudinal axis Y spaced apart from the first axis X, and substantially parallel thereto. - A
plunger member 80 andelastic means 90, for example a compression spring, may be inserted within the workingchamber 70 for mutually interacting, thus promoting the sliding along the axis Y between a position proximal to thebottom wall 71 and a position distal therefrom. - To this end, the
plunger member 80 may include afront face 81 having a generally rounded shape susceptible to come into contact with an substantially flatoperative surface 61 of thecurved cam element 60 so that the rotation of the latter around the axis X corresponds to the sliding of theplunger 80 along the axis Y and vice-versa. - To allow the reciprocal action of the
plunger member 80 onto thecam element 60, the elastic means 90 may act on the former to move it back from the proximal position to the distal one. To this end, the elastic means 90 may be placed in the workingchamber 70 so that their position of maximum elongation corresponds to the distal position of theplunger 80, while the one of minimum elongation corresponds to the proximal position of the latter. - On the other hand, in another embodiment, the elastic means may be placed in the working
chamber 70 so that their position of maximum elongation corresponds to the proximal position of theplunger 80, while the one of minimum elongation corresponds to the distal position of the latter. In this case, theplunger member 80 and the cam one 60 may be mechanically connected each other. - Depending on the configuration and/or the size of the elastic means 90, in this way it will be possible to automatically close the door D from the open position or simply return the
plunger member 80 to the distal position so that it interacts with thecam element 60 upon the opening or closing of the door. - This action depends on the configuration of the
cam element 60, and more particularly by the inclination of itsoperative surface 61. In fact, depending on the latter upon opening of the door D theplunger member 80 may move from the distal position to the proximal one, such as in the embodiment shown inFIGs. 10 to 18b , or from the proximal to the distal position, such as in the embodiment shown inFIGs. 19 to 22b . - Advantageously, the
front face 81 of theplunger member 80 may be made of a metallic material, for example steel, which may be harder than the metal material in which the workingsurface 61 of thecam element 60 is made. In this way, thefront face 81 will create a guide channel along theoperative surface 61 during use. - In a preferred but not exclusive embodiment, the working chamber may further include a working fluid, such as oil, acting on the
plunger member 80 to hydraulically counteract the action thereof. In this case, theplunger member 80 may separate the workingchamber 70 in a first and a secondvariable volume compartment - A
hydraulic circuit 100 may further be provided for the flow of the working fluid between the first and the secondvariable volume compartment front face 81 from the other of the distal or proximal positions to the initial one. - Advantageously, the
plunger member 80 may include one-way valve means for controlling the passage of the working fluid between the first and thesecond compartment front face 81 from one of the distal or proximal positions to the other of the proximal or distal positions. - Suitably, the valve means may include a control element, such as a
stopper 82, sliding in aseat 83 unitary movable with theplunger member 80. Thestopper 82 slides along the axis Y for selectively stopping/release a first inlet/outlet port 84 of theseat 83, so as to selectively open/close the fluid connection between the first and thesecond compartment - In particular, the
seat 83 may include, besides the first inlet/outlet port 84, a second inlet/outlet port 85, which may have a flow section greater than the one of the first inlet/outlet port 84. Suitably, theseat 83 may be dimensioned to allow the sliding of thestopper 82 along the axis Y. - The
stopper 82, the first inlet/outlet port 84 and the second inlet/outlet port 85 may be dimensioned so that when thestopper 82 frees the first inlet/outlet port 84, the working fluid leaks through the second inlet/outlet port 85 to put in fluid communication the first and thesecond compartment stopper 82 stops the first inlet/outlet port 84, the working fluid is forced to pass through thecircuit 100. - In a preferred but not exclusive embodiment, the
plunger member 80 may include atubular element 86 with afront portion 87 placed in thesecond compartment 73, arear portion 88 placed in thefirst compartment 72 and aside wall 89 facing theside wall 74 of the workingchamber 70. - The front and
rear portions tubular element 86 may be in fluid communication to each other and with theseat 83 of the valve means. To this end, thetubular element 86 may include a disk-shaped element 88' interposed between therear portion 88 thereof and the elastic means 90 which may include theseat 83, thestopper 82, the first inlet/outlet port 84 and the second inlet/outlet port 85. - In a preferred but not exclusive embodiment, the
plunger member 80 may further include astem 110 with afirst end 111 unitary coupled with thefront portion 87 of thetubular element 86 and asecond end 112 that includes thefront face 81. - More particularly, the
stem 110 may include a longitudinal passing-throughhole 113 with a first inlet/outlet opening 114 and a pair of second inlet/outlet openings 115, 115'. - The
stem 110 may be inserted through thefront portion 87 of thetubular element 86 so that theopening 114 is put in fluid communication with the first and second inlet/outlet port seat 83 of the valve means and so that the second inlet/outlet openings 115, 115' are put n fluid communication with thesecond compartment 73. - In this manner, the first and the
second compartment hole 113 of thestem 110, which may be connected with thetubular element 86 by means of thepin 116. - Advantageously, the
hydraulic circuit 100 may be made within the box-shapedhinge body 11 externally to the workingchamber 70 and may have a first inlet/outlet opening 101 in thesecond compartment 73 and a second and a third inlet/outlet opening first compartment 72. - In a preferred but not exclusive embodiment, shown for example in
FIGs. 15 to 22b , the valve means may be configured to close upon the passage of thefront face 81 of theplunger member 80 from the distal position to the proximal one, so as to force the working fluid to pass from thefirst compartment 72 to thesecond compartment 73 by entering in thehydraulic circuit 100 through the second andthird opening first opening 101. - In this case, the valve means may open upon the passage of the
front face 81 from the proximal position to the distal one, so as to allow the passage of the working fluid from thesecond compartment 73 to thefirst compartment 72 therethrough. To this end, the second inlet/outlet port 85 of theseat 83 may be faced to thefirst compartment 72, while the first inlet/outlet port 84 may be faced to thesecond compartment 73. - In such embodiments, the
third opening 103 may remain fluidly decoupled from theside wall 89 of thetubular element 86 over the entire stroke of theplunger member 80 from the distal position to the proximal one. - On the other hand, the
second opening 102 may remain fluidly decoupled from theside wall 89 of thetubular element 86 for a first starting part of the stroke of theplunger member 80, shown inFIGs. 17a and21a , and may be fluidly coupled with theside wall 89 for a second final part of said stroke, shown inFIGs. 18a and22a . - This way, the door D will have a first resistance to the closing/opening movement for a first angular portion α1 of the rotation thereof around the axis X corresponding to the first starting part of the stroke of the
plunger member 80, and a second resistance to the closing/opening movement of the door D for a second angular portion α2 of the rotation thereof around the axis X corresponding to the second final part of the stroke of thesame plunger member 80. - Suitably, first and
second means third opening - Thanks to this features, it will be possible for a user to independently adjust the first and the second resistance to the opening/closing movement of the door D.
- In such embodiments, the elastic means 90 may include a restoring spring, i.e. a spring whose size and/or configuration is sufficient to move the plunger member from the proximal position to the distal one but not to ensure the automatic closing of door D from the open position.
- The hinge so configured is a control hinge for controlling the rotatable movement of the door D.
- In particular, in the embodiments in which the
cam element 60 is configured in such a manner that upon opening of the door D the plunger member moves from the proximal position to the distal one, such as in the embodiments shown inFIGs. 15 to 18b , thehinge 1 is designed to control the rotatable movement of the door D upon its opening. - On the other hand, in the embodiments in which the
cam element 60 is configured in such a manner that upon opening of the door D the plunger member moves from the proximal position to the distal one, such as in the embodiments shown inFIGs. 19 to 22b , thehinge 1 is designed to control the rotatable movement of the door D upon its closure. - In an alternative embodiment, shown for example in
FIGs. 10 to 14b , said valve means may be configured to open upon the passage of thefront face 81 of theplunger member 80 from the distal position to the proximal one, so as to allow the passage of the working fluid from thefirst compartment 72 to thesecond one 73, and to close upon the passage thereof from the proximal position to the distal one, so as to force the working fluid to pass from thesecond compartment 73 to thefirst compartment 72 by entering thehydraulic circuit 100 through thefirst opening 101 and by exiting therefrom through the second and thethird openings - To this end, the second inlet/
outlet port 85 of theseat 83 may face thesecond compartment 73, while the first inlet/outlet port 84 may face thefirst compartment 72. - In this embodiment, the
third opening 103 of thecircuit 100 may remain fluidly decoupled from theside wall 89 of thetubular element 86 over the entire stroke of theplunger member 80 from the proximal position to the distal one, so that the door D has a third predetermined closing speed. - On the other hand, the
second opening 102 of thecircuit 100 may be fluidly coupled with theside wall 89 of thetubular element 86 for a first starting part of the stroke of theplunger member 80, shown for example inFIG. 14a , so that the door D has a predetermined closing speed. - The
second opening 102 may remain fluidly decoupled from theside wall 89 of thetubular element 86 for a second final part of the stroke of theplunger member 80, shown for example inFIG. 13a , so as to impart to the door D a latch action towards the closed position. - Advantageously, third means 122 may be provided for the regulation of the flow section of the
second opening 102, for example a suitable screw, so as to allow a user to adjust the force by which the door D latches towards the closed position. - fourth means 123 may further be provided for the regulation of the flow section of the
third opening 103, so as to allow a user to adjust the closing speed of the door D. - In this embodiment, the
cam element 60 may be configured so that upon opening of the door D theplunger member 80 moves from the proximal position to the distal one. - Suitably, the elastic means 90 may include an actuating spring, i.e. a spring whose size and/or configuration is sufficient to ensure the automatic closing of the door D from the open position.
