Detailed description of some preferred embodiments

With reference to the attached figures, is a unit described? control 1, which will be? particularly useful for controlling the flow of a working fluid, preferably an incompressible working fluid, e.g. oil.

The unit of control 1 potr? have any use, for example potr? be used as a single-sided shock absorber, as illustrated in FIGS. 59 ? 60B, or bilateral, as illustrated in FIGS. 61? 64B.

The unit of control 1 potr? otherwise? be used in any device. For example, the shock absorbers illustrated in FIGS. 59 - 64B can be used in machine tools or sliding doors.

In particular, the unit? of control 1 potr? be employed in a hinge device 100, as illustrated in FIGS. from 5 to 8, from 15 to 28B, from 33 to 41, from 47 to 51 and from 56 to 58.

It is understood that the mention of one or more? figures in relation to particular embodiments of the invention ? to be considered as an example and not a limitation of the same invention. The same embodiment could be illustrated in other figures, even if not specifically mentioned.

Essentially, the unit? of control 1 potr? be composed of a main body 10 in which two or more? stems 20?, 20??.

Even if in the following we will refer? to a?unit? of control 1 with two stems 20?, 20??, it is understood that the unit? of control 1 potr? include also pi? of two stalks without thereby departing from the scope of protection of the attached claims. Of course, a? unit? of control 1 which includes pi? of two stems will be? configured accordingly.

The present invention could include various parts and / or elements that are similar or the same. Where not otherwise specified, similar or equal parts and/or elements will be indicated with a single reference number, it being understood that the technical characteristics described are common to all similar or equal parts and/or elements.

The main body 10 will be able to include two working chambers 11 and 12 side by side and defining respective axes Y? and Y??, which may preferably be substantially parallel, but also substantially coincident, as illustrated in the embodiment of FIGS. 63 ? 64B, or substantially perpendicular, as illustrated in the embodiment of FIGS. 60B and 61 ? 62B.

Those Y axes? and Y?? will they be able to define the sliding axes of the two rods 20?, 20??. The working chambers 11, 12 will be able to include the working fluid, which will flow? within the same under the thrust of the stems 20?, 20??.

Each work chamber 11, 12 will be able to include respective openings of ends? 13?, 13?? and 14?, 14??, which can preferably be placed along the axes Y? and Y??.

The two stems 20?, 20?? can be inserted into the working chambers 11, 12 through the openings 13?, 14?, so as to present ends? 21?, 22? internal to the work chambers 11, 12 and extremity? opposite 21??, 22?? to these external.

On the other hand, the openings 13??, 14?? can be fluidly connected to each other through the duct 15, which can preferably be substantially perpendicular to the Y axes? and Y??, but also parallel to only one of them, as illustrated in the embodiment of FIGS.61 ? 62B.

The geometry and relative positions of the components illustrated above are not to be understood as limiting, but only as illustrative of the invention. The geometry and relative positions of the components may be any, without thereby departing from the scope of protection of the attached claims.

Thanks to the above characteristics, the sliding of the rod 20? along the Y axis? from?opening 13? towards that 13??, will correspond? to sliding in the opposite direction of rod 20?? along the Y axis?? from?opening 14?? towards that 14?, and vice versa.

The working fluid flow through the fluidic linkage defined by the openings 13??, 14?? and from duct 15, in fact, far? so that the sliding of the stem 20? along the Y axis? from the distal position of the extremity? 21? from the opening 13?, illustrated for example in FIG. 3A, towards the one proximal thereto, illustrated for example in FIG. 3B, will correspond? sliding in the opposite direction of the stem 20?? along the Y axis?? from the proximal position of the extremity? 22? to the opening 14?, illustrated for example in FIG. 3A, towards the one proximal thereto, illustrated for example in FIG.3B, and vice versa.

In practice, the working fluid will transmit? the thrust exerted on one of the two rods 20?, 20?? from the outside to the inside of the main body 10 on the other stem, which will come? pushed from inside to outside.

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

Even if in the following we will refer? to a single adjustment element 40, it is understood that the unit? of control 1 potr? include also pi? of a regulating element without thereby departing from the scope of protection of the attached claims. Of course, a? unit? of control 1 which includes pi? of an element of regulation sar? configured accordingly.

Conveniently, the adjustment element 40 can be at least partially inserted into the fluidic connection line defined by the openings 13??, 14?? and from the duct 15 to interact with at least one passage section thereof, thus regulating? the flow of the working fluid.

In a preferred but not exclusive embodiment, illustrated for example in FIGS. from 1 to 8, the adjustment element 40 can? be a shutter element, for example a pin having diameter D40, movable between two lower and upper passage sections 15?, 15?? of the duct 15, having diameters D15 respectively? and D15??.

Conveniently, the diameter D40 ? slightly lower than the diameter D15?, for example by a few tenths of a millimetre, and the diameter D15? ? slightly smaller than the D15?? diameter, always a few tenths of a millimeter for example.

Thanks to the configuration above, when the plug 40 ? in the lower passage section 15?, the flow of working fluid passing in the interspace between the latter ? lower than the one passing in the interspace between the same pin 40 and the upper passage section 15??.

The reciprocating sliding of the pin 40 between the two lower and upper passage sections 152, 15?? can I take place thanks to the oil pressure imparted by the movement of the rods 20?, 20??.

In a further preferred but not exclusive embodiment, illustrated for example in FIGS. from 11 to 64B, the adjustment element 40 can? include a screw element 41 engaged in a nut 17 to widen / narrow the passage section 15??? of duct 15.

could moreover, a cap element 42 is provided elastically forced by a spring 43 against the end? 41?? of the screw element 41, which could? also present a? extremity? free opposite 41? controllable from the outside by an operator. It is understood that the plug element 42 could also simply slide without spring 43, without thereby departing from the scope of protection of the attached claims.

Fittingly, the step section 15??? of the duct 15 potr? present substantially truncated cone shape, cos? as the? extremity? 41?? of the screw element 41. Preferably, the passage section 15??? can I be calibrated.

At the end? 41?? can I be provided for a passage light 44??, which could? be fluidly communicating with the opening 13?? and can be selectively closed by the plug element 42.

At the end? 41?, moreover, could? be provided for a passage light 44?, which could? be fluidly communicating with the opening 14??.

Furthermore, the screw element 41 can include an inner conduit 45 extending between passage ports 44?, 44?? to place them in mutual fluidic communication.

Conveniently, the plug element 42 can substantially present the shape of a mushroom, with a? extremity? enlarged 42? at the end? 44?? and a stem 42?? slidably inserted into the inner duct 45 of the screw element 41.

The spring 43 will be able be suitably sized so that when the stem 20?? flows from the distal position illustrated for example in FIG. 13A to the proximal one illustrated for example in FIG. 14A the plug element 42 opens, freeing the passage port 44?? and allowing the working fluid to pass in a controlled manner through the gap between the internal conduit 45 and the stem 42?? of the plug element 42.

Upon the reverse passage, however, the cap element 42 will close, plugging the passage port 44?? and forcing the working fluid to pass in a controlled manner through the passage section 15???.

In fact, therefore, the spring assembly 43 ? plug element 42 acts as a one-way valve means for controlling the flow of the working fluid.

The passage of the working fluid through the conduit 15 will be always checked both ways. The difference in diameters between the internal duct 45 and the stem 42?? of the cap element 42, in fact, controller? the passage of the working fluid in one direction, while the size of the passage section 15??? controller? the passage of the working fluid in the reverse direction.

In order to protect the unit? control 1 against any sudden increases in pressure in the same, can? a pressure relief valve element 50 should be provided lying in a conduit 18 fluidly connected to the conduit 15.

The overpressure valve element 50 could? include a spring 51 and a shutter 52, for example a ball shutter, elastically forced against a seat formed in the duct 18. The spring 51 and the shutter 52 can be held in the operating position by a grub screw 53.

Conveniently, the spring 51 can be sized so that the obturator 52 only opens when the pressure inside the working chambers 11, 12 or in the duct 15 exceeds a predetermined threshold value, calculated so as to avoid damage to the unit? control 1.

Advantageously, the unit? of control 1 potr? include elastic means of contrast, such as one or more? coil springs 30.

Depending on the function of the device where the unit? control 1 will be? inserted, the one or more? springs 30 could be thrust or reset springs.

Advantageously, each spring 30 can be inserted coaxially on the respective stem 20?, 20?? and interposed between an abutment surface 16 of the main body 10 and an abutment surface 23 of this rod 20?, 20??. Alternatively, the spring 30 could be placed inside the stem, as illustrated in FIGS.59 ? 60B.

Conveniently, the one or more? springs 30 can act exclusively on one of the stems, for example the stem 20??, while the other stem, for example the stem 20?, can be free to scroll along its respective Y-axis? without elastic contrast.

For the purpose, in case of unity? control 1 which includes two springs 30, such as for example in the embodiments illustrated for example in FIGS. 29, 43 and 52, can I a matching element 31 may be provided which is fixed to the stem on which the springs 30 act, for example the stem 20??.

The matching element 31 could? include the abutment surfaces 23 for the springs 30 and could? further include a through seat 32 for the stem 20?. In this way, the latter can? scroll freely along the Y axis? without elastic contrast.

Advantageously, as better illustrated below, the matching element 31 can include the cam follower means 25??, while the stem 20? can I include or be integral with the cam follower means 25?.

Thanks to the above, the action of one or more? springs on stem 20?? will be independent from the fluid flow control action exerted by the unit? of control 1 on both stems 20?, 20??.

Consequently, thanks to the functional independence between the springs and stems, even in the event of sudden pressure exerted from the outside on one of the stems, the other stem will be? always checked, and the stem on which the springs will return? always in the maximum distal position.

In a preferred but not exclusive embodiment, the unit? of control 1 potr? be particularly useful for controlling the flow of a working fluid in a hydraulic hinge device 100.

The latter can be particularly useful for the controlled rotational movement of a closure element P, such as for example a door, a wing or the like, with respect to a stationary support structure S, such as a floor, a frame or the like.

Even if in the following we will refer? to a door P and to a floor or frame S depending on the various embodiments of the hinge device 100, it is understood that the latter could? be connected to any closure element and any stationary support structure without thereby departing from the scope of protection of the attached claims.

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

Depending on the configuration, the hinge device 100 will be able to be a closing hinge, as for example illustrated in FIG. 5A or 15 , or a hydraulic control hinge, such as illustrated in FIG. 6 or 23. In the first case, the hinge device 100 can include one or more thrust springs 30, while in the second case the hinge device 100 could include a reset spring or be without springs.

In use, ? is it possible to mount two or more on a door P? hinge devices 100, for example two closing hinges or one closing and one hydraulic control, or a closing or control hinge device 100 and a hinge, without particular limitations.

For illustrative and non-limiting example, ? Is it possible to mount on a TP glass folding table one or more? hydraulic control hinge devices 100, as illustrated in FIGS. 28A and 28B .

In a preferred but not exclusive embodiment, illustrated for example in FIGS. from 5A to 10C, the hinge device 100 can be a flat hinge particularly suitable for being inserted into the tubular frame of a refrigerator door.

In a further preferred but not exclusive embodiment, illustrated for example in FIGS. from 15 to 27, the hinge device 100 can? be a two-handed hinge for frameless glass doors.

In a further preferred but not exclusive embodiment, illustrated for example in FIGS. from 33 to 41, the hinge device 100 can be a folding hinge for internal doors to make it ambidextrous, to be anchored to a floor S by means of a compass B, in itself? Note.

In a further preferred but not exclusive embodiment, illustrated for example in FIGS. from 47 to 51, the hinge device 100 can be an ambidextrous hinge for pivot mounted frameless glass doors, to be anchored to a floor S.

In a further preferred but not exclusive embodiment, illustrated for example in FIGS. from 56 to 58, the hinge device 100 can be an ambidextrous recessed door closer for internal doors, to be anchored to the door frame S by means of an articulated arm A, in itself? known.

Advantageously, the hinge device 100 can generally comprise a hinge body 110, which can be integrally anchored to the door P or to the stationary support structure S depending on the embodiment, as shown in the accompanying figures. For example, in the preferred but not exclusive embodiment illustrated in FIGS. from 15 to 27, the hinge body 110 can be anchored to the frame S, while in the preferred but not exclusive embodiment illustrated in FIGS. from 47 to 51, the hinge body 110 can? be anchored to port P.

As better illustrated pi? ahead, the hinge body 110 will be able to comprise various pieces, depending on the embodiment. In general, however, can comprise or be constituted by at least one shell 111, possibly composed of two or more? half shells 111?, 111?? as in the preferred but not exclusive embodiment illustrated in FIGS. from 47 to 51, which internally includes at least one compartment 112, in which the unit? pin 1 and a pin 200.

In the embodiments illustrated in FIGS. from 1 to 58 the unit? of control 1 potr? be removably inserted in the compartment 112 to define the hydraulic portion, with the ends? 21??, 22?? of the stems 20?, 20?? protruding from the main body 10 to remain in the dry portion 113 of the compartment 112, where they will interact with the pin 200.

The latter can define an X axis, what will it do? also from the axis of mutual rotation between the pin itself 200 and the hinge body 110.

The pin 200 could? present one or more portions 201 for coupling with the door P or the stationary support structure S and first and second cam means 210, 215.

The latter may be mutually placed side by side or superimposed, and may have such a configuration as to mutually interact in a selective and alternative manner respectively with the stem 20?? and that 20?, and preferably with corresponding first and second cam follower means 25?, 25?? integrally coupled respectively with the latter, as better explained below.

In particular, the first and second cam follower means 25?, 25?? they can be monolithic with the first and second stem 20?, 20?? to define their respective ends? opposite 22?, 22??, as for example in the embodiments of FIGS.1? 10C, or could they be integrally coupled with the latter, as for example in the embodiments of FIGS.11? 58.

There? promote? the reciprocating motion of the rods 20?, 20??, so that the sliding of the rod 20? from?opening 13? towards? opening 13??, cio? of? end? 21?? from the distal to the proximal position, corresponds to the sliding of the stem 20?? from?opening 14?? towards? opening 14?, cio? of? end? 22?? from the proximal position to the distal one, and vice versa, the sliding of the stem 20?? from?opening 14? towards? opening 14??, cio? of? end? 22?? from the distal to the proximal position, does it correspond to the sliding of the stem 20? from?opening 13?? towards? opening 13?, the cio? of? end? 21?? from the proximal to the distal position.

As illustrated above, during these passages the working fluid will dampen? the closing and/or opening movement of the door hydraulically.

Even if in the following we will refer? to a hinge device 100 which automatically closes the door P and hydraulically dampens its closing and opening movement, it is understood that the hinge device 100 could only hydraulically dampen the closing and opening movement of the door P, as for example illustrated in the embodiments of FIG. 6 or 23, without thereby leaving the scope of protection of the attached claims.

The pin 200 and the unit? of control 1 can be configured in such a way that the distal and proximal positions respectively of the stems 20??, 20? corresponds to that of closed port P and the proximal and distal positions respectively of the stems 20??, 20? corresponds to that of door P open.

For this purpose, the cam means 210, 215 can be suitably configured. In particular, depending on the embodiment of the hinge device 100 and of the relative pin 200, the cam means 210, 215 will be able to define respective axes or planes that are substantially perpendicular to each other.

In any case, the cam means 210, 215 and the stems 20??, 20? will be able to interact and rotate reciprocally around the X axis between a closed door position and an open door position in which the stems 20??, 20? they will be able to assume the positions described above, scrolling along the respective axis Y??, Y?. It will be understood that depending on the embodiments one of the cam means 210, 215 and the stems 20??, 20? they will rotate and the others will be stationary.

In particular, during the opening of the door P the cam means 210 will be able to push the stem 20?? to scroll along the Y axis?? from the distal position of its extremity? 22?? to the proximal one. At the same time, the oil present in the chambers 11, 12 will push? the stem 20? to flow along Y? from the proximal position of its extremity? 21?? to the distal one. During this movement will the cam means 215 rotate in relation to the stem 20? to allow scrolling above, and one or more? springs 30 will be compressed from the position of maximum extension to that of maximum compression.

Conveniently, during this movement the cam means 215 and the end? 21?? of stem 20? may be mutually spaced and not in contact.

The pressure inside the circuit will carry? the cap element 42 to open or the pin 40 in the portion 15?? of the duct 15 with a larger diameter, allowing the oil to pass through the duct 15.

In embodiments where ? present the spring assembly 43 ? plug element 42, as illustrated above, this passage will take place? through the tubular gap between the internal duct 45 and the stem 42?? of the plug element 42.

This tubular cavity, therefore, will define? the maximum opening force acting on door P, even in the event of sudden forcing due, for example, to a gust of wind or an incautious user. Even in this case, in fact, the door will be? always controlled and protected from unwanted shocks and possible damage.

On the other hand, during the closing of the door P, one or more? springs 30 will be able to promote the movement of the rod 20?? along the Y axis?? from the proximal position of its extremity? 22?? to the distal one and rotation of the door P towards the closed position. At the same time, will the cam means 215 push the rod 20? to flow along Y? from the distal position of its extremity? 21?? to the proximal one.

The pressure inside the circuit will carry? the cap element 42 to close or the plug 40 in the portion 15? of the duct 15 with a smaller diameter, allowing the oil to act to hydraulically dampen the movement of the closing door P, as described above.

It will be understood that in the embodiments wherein the hinge device 100 is without springs the pushing force can? be given by an external force, for example an external closing hinge or gravity, and the hinge device 100 will act? essentially as a hydraulic brake to hydraulically dampen the closing movement of door P.

Thus, the movement of the door ? always controlled both in closing and in opening, even in the event of sudden forces acting on door P, for example a gust of wind or the push of an incautious user. On the other hand, in the event that this thrust endangers the integrity? of the hinged device 100 the overpressure valve element 50 would open, protecting it.

During the closing of the door, one or more? springs 30 will act on the cam follower means 25??, which in turn will act on the cam means 210 to move the pin 200 and the door P. This movement ? independent from the hydraulic one of the rods 20?, 20??.

In particular, the movement of the spring unit 30 ? cam follower 25?? ? cam 210 will be? independent of stem movement 20??. The latter, in fact, sar? driven to scroll along the Y axis?? only by the action of the other rod 20?, which in turn will be? driven by cam 215 acting on follower 25?.

This independent movement, together with the particular configuration of the cam follower 25?, will allow to obtain a mechanical click in closing, as better illustrated pi? after you.

The hinge device 100 can be advantageously substantially planar. In particular, the Y?, Y?? Will they be able to come up with a plan? substantially perpendicular to the X axis, as for example in the embodiments of FIGS. 5A ? 10C and 33 ? 42, or to this parallel, as for example in the embodiments of FIGS. 15 ? 27, 48 - 51 and 56 ? 58.

In the latter embodiments, the first and second cam means 215, 210 and the first and second cam follower means 252, 25?? Can they be mutually superimposed along the plane? defined by the Y?, Y?? axes.

In particular, the cam means 210 could include or consist of a space with a planar surface 211 substantially perpendicular and parallel to the plane ? respectively in the closed and open positions of the door P, as for example illustrated respectively in FIGS.18C and 20C.

On the other hand, the cam follower means 25?? may include or consist of a flat face 260 substantially perpendicular to the plane ? both in the closed position and in the open position of the door P, as for example again illustrated respectively in FIGS.18C and 20C.

Furthermore, the cam means 215 could include or consist of a space with a pair of opposite flat walls 216 substantially parallel and perpendicular to the plane ? respectively in the closed and open positions of the door P, as for example illustrated respectively in FIGS.18B and 20B.

Between the two walls 216 potr? be placed a portion of the end? 217, intended to come into contact with the cam follower means 25? in the closed position, illustrated for example in FIG. 18B, and be spaced apart from and not touching in the open position, illustrated for example in FIG. 20B. Pi? precisely, the contact area 217? , which can be placed in a central position with respect to two flat and tapered surfaces 217?? and 217???, of the portion of the extremity? 217 can be substantially flat and perpendicular to the walls 216.

On the other hand, the cam follower means 25? will they be able to include a flat face 26? substantially perpendicular to the plane ? both in the closed and in the open position of the door P, as for example again illustrated respectively in FIGS.18B and 20B.

This flat face 26? can I be positioned centrally with respect to two flat tapered surfaces 26??, 26???, and may contact the cam means 215 to define the stop positions at 0? and 90?.

Pi? precisely, the flat surface 26? can I come in contact with the contact area 217? of the portion of extremity? 217 in the closed position, illustrated for example in FIG. 18B, and with one of the walls 216 in the open position, illustrated for example in FIG.20B.

There? allow? not only to obtain a stable stop position in the closed and in the opening positions, but also to obtain a mechanical click of the door P towards the closed position.

Starting from the open position illustrated for example in FIG. 20B, in fact, the cam means 215, initially in contact with one of the walls 216, will rotate around the axis X, pushing on the cam follower means 25?. As a result of this rotation, the flat surface 26? can I first come into contact with one of the surfaces 217?? or 217???, depending on the opening direction, and then with the contact area 217? of the portion of extremity? 217.

When passing from one of the surfaces 217?? or 217??? to the contact area 217?, the flat surface 26? will not have more a contact with a surface but with a point, as illustrated in FIG. 20D .

Consequently, the cam means 215 will undergo a sudden and uncontrolled rocking about the point of contact with the cam follower means 25? the flat surface 26? and the contact area 217? they will not be in mutual contact to define the stop position in closing. There? causes, thanks to the fact that the thrust of the spring 30 ? continuous and independent of the hydraulic control, a mechanical click of the hinge device 100 towards the closed position.

By suitably configuring the profile of the cam means 215 and of the cam follower means 25? will be It is possible to predetermine the point at which this shot occurs. On the other hand, the force of the shot will be? determined by the force of the spring 30.

Is it also understood? than by configuring the cam follower means 25? or those with cam 215 so that they lack the plane 26? hinged devices may not have a snap.

In the embodiments of FIGS.5A ? 10C and 33 ? 42, the cam means 215, 210 and the cam follower means 25?, 25?? will they be able to lie on a plane substantially parallel or coincident with the plane? identified by the axes Y?, Y??.

Conveniently, the cam means 215, 210 may extend perpendicularly from the first axis X to contact the first and second cam follower means 252, 25?? and move the stems 20?, 20?? as described above.

In particular, the cam means 215, 210 could have surfaces 26, 26?? and 260 intended to interact with the surfaces 217 and 211 of the cam follower means 25?, 25??.

Similarly to the above, in the vicinity? of the closed position the cam means 215 will rock about the point of contact between the surfaces 26 and 26?? until? surface 26? not go in contact with the surface 217, defining the closed stop position.

It will be understood that the profile of the cams and cam followers of the embodiments illustrated herein only exemplary, and could? be configured according to the motion to be imparted to door P in opening or closing.

With particular reference to the embodiment of FIGS. 33 ? 38, block 31 will be able to include the cam means 25??, while on the stem 20? can I be fitted on the cam follower 25?. There? simplifies the installation of the hinge as much as possible.

In this embodiment, the pin 200 can be configured to impact against the shell 111 in both opening and closing, as illustrated in FIGS. 35 and 37. In closing, there? allows you to give a preload to the door P, which will push? against its leaf. During opening, this device also acts as an anti-unhinging device for door P, preventing it from impacting any obstacles. For this purpose, both followers 25?, 25?? they can be equipped with an exhaust for the cams 210, 215.

As an alternative to the cam and cam follower means, in a preferred but not exclusive embodiment illustrated for example in FIGS. 39 ? 40B the pin 200 will be able? have pinion means 220 capable of interacting with corresponding rack means 27?, 27?? integrally coupled respectively with stems 20?, 20??. The rack means 27?? may be included in block 31, which in turn may be inserted by means of a pin on the stem 20??. On the other hand, the rack means 27? can be removably inserted on stem 20?, which can slide freely through the opening 32.

This embodiment allows maximum control over port P, which will close? always from any opening position.

The assembly of the hinge device 100 ? very simple, since? base in the compartment 112 must be inserted?unit? control 1 with the cam follower means and the pin 200, all pre-assembled as a pack, and then the shell 111 is closed with a closure element. Eventually, finishing covers may be provided.

Advantageously, the adjustment element 40 can be accessible even with the hinge device mounted, possibly by removing a finishing cover.

In the embodiment of FIGS. 15 ? 27, 33? 38, 39? 40B and 56 ? 58, in fact, the adjustment element 40 could? be accessible through an opening 160, while in the embodiment of FIGS. 48 ? 51 the adjustment element 40 could? be accessible by removing the cover 161.

With particular reference to the embodiment of FIGS. 15 ? 27 the shell 111 will be able present slide guides 125?, 125?? into which to slidably insert into cam follower means 25?, 25??. There? render? the assembly of the hinge extremely simple, and the movement exceptionally smooth.

Again with reference to this embodiment, after inserting the pin 200 and the cam follower means 25?, 25?? into the shell 111 in the guides 125?, 125??, sar? sufficient to screw to the same shell 111 the?unit? control 1, by means of the screws 130 passing through the body 10.

At that point, to complete the assembly, it is sufficient to screw the above assembly to the fixing plate 140 using the screws 141. This type of assembly makes this hinged device particularly versatile, because it can be used in many ways. the same assembly? mountable on various types of 140 plates.
