Detailed description of some preferred embodiments

With reference to the mentioned figures, the hinge 1 shall be advantageously suitable to be used for the controlled rotary movement of at least one closing element D, such as for example a door, a leaf or the like, which may be anchored in a per se known manner to a stationary support structure S, such as a wall, a floor, a frame or the like.

By way of non-limiting example, the hinge 1 may be used for doors made of glass, interior doors made of wood, aluminium or PVC, shower doors or fridge doors.

Advantageously, the closing element D may have a main extension plane nD, while the stationary support S may define a main extension plane nS.

Such planes may be mutually incident, for example perpendicular, as shown in fig. 12A and 12B, or not perpendicular as shown in fig. 12C to 12F.

In this case, the closing element D will be inclined.

Preferably, the hinge 1 will be anchorable to the stationary support structure S in any manner and will lie above the plane of the floor underlying the closing element.

In a preferred but non-exclusive embodiment, the hinge 1 may comprise a fixed element 10 anchorable to the closing element D or to the stationary support structure S and a movable element 20 anchorable to the closing element D or to the stationary support structure S.

In the embodiment described herein, the movable element 20 may include a pin 21.

However, it is clear that the hinge 1 may also be without the pin 20, for example as disclosed by the international application PCT/IB2015/052183, on behalf of the Applicant in question, to which reference shall be made for consultation. In this case, the operative connection between the movable part and the fixed part of the hinge is guaranteed by a lever assembly.

In the embodiment described herein, the fixed element 10 may include a hinge body 11 anchorable to the stationary support structure S, while the movable element 20 may include a pin 21 which can be connected with the closing element D.

Thus, the box-shaped hinge body 11 will be fixed, while the pivot 21 will be rotatable.

However, it is clear that the opposite may also occur, that is a fixed element 10 may include a pin 21 anchorable to a stationary support structure S, while the movable element 20 may include a hinge body 11 which can be connected with the closing element D without departing from the scope of protection of the attached claims.

In particular, the hinge body 11 may be box-like, with an extension along an axis Y, and it may include an end 11' with a cylindrical seat 12 with extension along an axis Z, with an inner side wall 12'.

In a preferred but non-exclusive embodiment, the hinge body 11 may be particularly compact, that is it may have dimensions with side measuring 25 mm by way of non-limiting example, considering the section of the hinge body 11 taken along a median plane nM thereof, perpendicular to the axis Y.

In the seat 12 there may be advantageously inserted the pin 21 or a part thereof.

Specifically, the pin 21 may extend along an axis X which may coincide with the axis Z and it may include a lateral surface 21' which may be arranged at least partially facing the side wall 12'.

However, it is clear that in the event there is no pin, the end 11' may however house the means which allow the rotary connection with the movable element 20.

On the other hand, the hinge body 11 may include an end 11" with an inner threaded portion 110 and susceptible to house a closing cap 80.

The latter may include a lateral surface 81 that is counter-threaded specifically so as to be screwed at the portion 110.

The cap 80 may also include a bottom wall 82 which is arranged facing the inner part of the hinge body 11.

Advantageously, the hinge body 11 may include a working chamber 13 which extends along the axis Y, which may therefore be substantially horizontal.

In the working chamber 13 there may slide along the axis Y a slider element 50 operatively connected with the pin 21, where present, or the rotary connection means with the movable element 20.

Depending on the configuration of the slider element 50, the hinge 1 may be a closing hinge or a control hinge.

The slider element 50 may include or not include elastic counteracting means 95.

Depending on the configuration thereof, such elastic counteracting means 95 may include a thrust spring, that is adapted to return the closing element D to the closed position from the open position and vice versa, or a return spring, that is adapted to restore the initial position of the slider element 50 but not adapted to return the closing element D to the closed position from the open position and vice versa.

On the other hand, the hinge 1 may be without elastic counteracting means.

Irrespective of the presence or absence of the elastic counteracting means 95, the slider element 50 may slide along the axis Y between a position proximal to the bottom wall 82, which may define the bottom wall of the working chamber 13, and a position distal therefrom.

In the embodiments shown in the figures, the proximal position corresponds to the closing element open position D, while the distal position corresponds to the closing element closed position D.

Where present, the proximal position corresponds to the maximum compression of the elastic counteracting means 95, while the distal position corresponds to the maximum elongation thereof.

The pin 21 and the slider element 50 may be mutually engaged so that the rotation of the of the former around the axis X corresponds to the sliding of the latter along the axis Y between the proximal and distal positions, and vice versa the sliding of the latter along the axis Y between the proximal and distal positions there corresponds the rotation of the former around the axis X.

To this end, the hinge 1 may include appropriate motion transmission means 30, in particular with a rotary portion integrally joined with the movable element 20 and a translating portion integrally joined with the slider 50. In the examples shown in the attached figures, the pin 21 may include or may be connected with a pinion element 22 with a plurality of shaped teeth 22' which may define the rotary portion mentioned above, while the slider element 50 may include or may be connected with a rack element 51 substantially parallel to the axis Y comprising a plurality of counter-shaped teeth 51' which may define the translating portion mentioned above.

As particularly clear in FIGS. 1 and 10, the shaped teeth 22' of the pin 21 and the counter-shaped teeth 51' of the slider element 50 may be operatively coupled to each other.

In this manner, the pin 21 and the slider element 50 may be always engaged to each other, so that there is the maximum control of the closing element D both when opening and closing.

As a matter of fact, in the event of a sudden opening for example due to a gust of wind or an incautious user, the constraint between the pin 21 and slider element 50 will prevent the closing element D from moving freely ending up impacting against its frame, being damaged irreparably.

This makes the hinge 1 extremely safely and reliably, for example as especially disclosed by the international application PCT/IB2014/063556, on behalf of the Applicant in question, to which reference shall be made for consultation.

However, it is clear that other motion transmission means 30 other than the pinionrack mechanism described above so as to allow the mutual rotation of the fixed element 10 and of the movable element 20 may be taken into account without departing from the scope of protection of the attached claims.

Furthermore, suitably the pin 21 may include at least one central operative portion in the working chamber 13.

Preferably, the pin 21 may include connection means 23 with the closing element D.

In the case of a unilateral hinge 1, the connection means 23 may include a male element 230, as particularly shown in FIG. 1.

In the case of an ambidextrous hinge 1, the connection means 23 may include a pair of female elements 231, as particularly shown in FIG. 11B.

According to a particular aspect of the invention, there may be provided for a system 2 for preventing the pin 21 from slipping off from the seat 12.

Below is the description of the anti-slip-off system 2 in case of a unilateral or ambidextrous hinge 1.

In the embodiment in particular shown in figs. 1 and 9B, that is in case of a unilateral hinge 1, the lateral surface 21' of the pin 21 may include an edge area 24' protruding with respect to the axis X in a direction radial therefrom.

Suitably, the system 2 may include a ring nut 40' with an outer lateral surface 41' with a threaded portion 410', an inner lateral surface 46', a lower surface 44' and possibly an upper flange 45'.

On the other hand, the side wall 12' of the seat 12 may include a threaded portion 120', while the seat 12 may include an edge area 121'.

From an operative point of view, the pin 21 may be inserted into the ring nut 40' so that the edge area 24' impacts the lower surface 44'.

Such first assembly may therefore be inserted into the seat 12 and the threaded portions 410' and 120' may be screwed to each other.

Therefore, it is clear that even the ring nut 40' may be arranged at least partially facing the side wall 12'.

If present, the flange 45' may come into contact with the edge area 121' of the seat 12.

It is therefore clear that the interaction between the edge area 24' and the lower surface 44', as well as the integrally joined coupling between the ring nut 40' and then hinge body 11 by screwing between the threaded portions 410' and 120' may prevent the pin 21 from slipping off from the seat 12.

Advantageously, in order to guide the rotation of the pin 21, as well as centre it in the seat 12, the system 2 may include a bushing 31.

The latter may include an inner surface 31', an outer surface 31" and possibly an upper flange 32.

Preferably, the bushing 31 may be made of polymeric material, for example marketed by IGUS®.

Specifically, the bushing 31 may be inserted between the surface 21' of the pin 21 and the surface 46' of the flange 40', at a portion 411' of the latter.

Even more specifically, the flange 32 may lie on the flange 45' of the ring nut 40'.

In this manner, the bushing 31, ring nut 40' and pin 21 may form a unitary assembly which can be inserted into the seat 12.

Should the hinge 1 be of the hydraulic type, as particularly explained below, the system 2 may include hydraulic sealing means 90.

For example, the latter may include an elastomeric gasket 91' and an oil seal 92'.

In order to ensure the hydraulic sealing of the working fluid, the surface 41' of the ring nut 40' may include a housing 42' for the gasket 91', while the surface 46' may include a housing 43' for the oil seal 92'.

It is therefore clear that the bushing 31, ring nut 40', pin 21 and the relative sealing means 90 may form a unitary assembly which can be inserted into the seat 12.

The description outlined above relating to the anti-slip-off system 2 for a unilateral hinge 1 may also apply to the embodiment shown in figs. 10 to 11B, that is in case of an ambidextrous hinge 1, with the addition of the characteristics below.

In this case, the pin 21 may include a half-pin 210 with the lateral surface 21' mentioned above and the edge area 24' and a half-pin 211 with a lateral surface 21" and an edge area 24" protruding with respect to the axis X in a direction radial therefrom.

Specifically, the half-pin 210 and the half-pin 211 may be symmetrical with respect to the axis Y and the rotary portion of the motion transmission means 30 may be interposed therebetween.

In the example mentioned above, the pinion 22 may remain interposed between the half-pin 210 and the half-pin 211 and it may be connected or connectable therewith in a per se known manner.

In addition, the edge areas 24' and 24" may remain arranged facing each other.

Suitably, the system 2 may include a ring nut 40" with an outer lateral surface 41" with a threaded portion 410", an inner lateral surface 46", a lower surface 44"and possibly an upper flange 45".

On the other hand, the seat 12 may be of the type passes through the hinge body 11 and the side wall 12' of the seat 12 may include a threaded portion 120", while the seat 12 may include an edge area 121".

In this case, the threaded portions 120' and 120" and the edge areas 121' and 121"may be positioned in an opposite manner along the axis Z, that is they may be mutually symmetrical with respect to the axis Y. In addition, the pin 21, that is the two half-pins 210 and 211, may be fully contained in the hinge body 11 so that the outer surface of the latter and the upper and lower surfaces of the pin 21 are flush.

Operatively, the half- pin 210 may be inserted into the ring nut 40' so that the edge area 24' impacts the lower surface 44'.

Such assembly may be inserted into the seat 12, as described above, and the threaded portions 410' and 120' may be screwed to each other.

On the other hand, the half- pin 211 may be inserted into the ring nut 40" so that the edge area 24' impacts the lower surface 44".

Such assembly may be inserted into the seat 12 as described above, and the threaded portions 410" and 120" may be screwed to each other.

Therefore, it is clear that even the ring nut 40" may be arranged at least partially facing the side wall 12'.

Furthermore, if present 45" the flange may impact the edge area 121".

It is therefore clear that the half-pins 210 and 211 may be inserted - from opposite sides - into the seat 12 along the axis Z.

Advantageously, in order to guide the rotation of the half-pins 210 and 211, as well as a centring them in the seat 12, the system 2 may include a bushing 31 as described above and a bushing 310 with an inner surface 310', an outer surface 310" and possibly an upper flange 320.

Preferably, also the bushing 310 may be made of polymeric material, for example marketed by IGUS®.

Specifically, the bushing 310 may be inserted between the surface 21" of the halfpin 210 and the surface 46' of the flange 40', at a portion 411" of the latter.

Even more specifically, the flange 320 may lie on the flange 45" of the ring nut 40".

In this manner, the bushing 310, ring nut 40" and half- pin 211 may form a unitary assembly which can be inserted into the seat 12.

Should the hinge 1 be of the hydraulic type, the hydraulic sealing means 90 may include a further elastomeric gasket 91" and a further oil seal 92".

In order to ensure the hydraulic sealing of the working fluid, the surface 41" of the ring nut 40" may include a housing 42" for the gasket 91", while the surface 46" may include a housing 43" for the oil seal 92".

It is therefore clear that the bushing 310, ring nut 40", half- pin 211 and the relative sealing means 90 may form a unitary assembly which can be inserted into the seat 12.

It is clear that the rotary portion of the motion transmission means 30, for example the pinion 22 mentioned above, may be connected to the half-pin 210 or to the half-pin 211 before they and their respective assemblies are inserted into the seat 12.

In this manner, the pack-pin assembly 21, understood as each of the assemblies described above comprising the pin 21, will be extremely easy.

Irrespective of the anti-slip-off system 2 described above, the hinge 1 may be mechanical or hydraulic.

Should the hinge 1 be hydraulic, the working chamber 13 may include a working fluid, generally oil, acting on the slider element 50 to counter-act the action thereof, therefore hydraulically controlling the closing and/or opening movement of the closing element.

In this case, the slider element 50 may be sealingly inserted into the working chamber 13.

In the present document, the expression "sealingly inserted slider" and derivatives is used to indicate that the slider 50 is inserted into the working chamber 13 with minimum clearance, such to allow it to slide therein but such to prevent the flow of the working fluid through the interspace between the lateral surface of the slider and the inner surface of the working chamber.

The slider 50 may act as a partitioning element of the working chamber 13 in a first and a second variable volume compartment 18, 19.

The latter, which will be placed in mutually fluidic communication as described below, may preferably be adjacent.

Advantageously, the first compartment 18 and the second variable volume compartment 19 may be configured to have - at the open position of the closing element D - the maximum and the minimum volume respectively. To this end, if present, the elastic counteracting means 95 may be arranged in the second compartment 19.

Furthermore, it is clear that the pin 21 may be at least partially inserted into the compartment 19 so as to be immersed into the working fluid, for example in oil bath.

In addition, also the motion transmission means 30 may be immersed into the working fluid, for example in oil bath.

This will allow to minimise the wear of the components and allow a facilitated and safe operation of the hinge 1 in the long-term.

In order to allow the through-flow of the working fluid between the first and the second compartment 18, 19, upon the opening and closing the closing element D, the hinge body 11 may include two cavities defining two hydraulic circuits 60, 70.

Such circuits may be fluidically independent and they may have a longitudinal extension, each parallel to the axis Y.

Preferably, such circuits 60, 70 may be substantially circular in plan view, that is they may have a cylindrical extension along axes parallel to the axis Y.

It is however clear that the circuits 60, 70 may have other shapes in plan view, without departing from the scope of protection of the attached claims.

The circuit 60 may include two opposite ends 60' and 60", in which the end 60' is fluidically connected with the compartment 18, while the end 60" is fluidically connected with the compartment 19.

On the other hand, the circuit 70 may include two opposite ends 70' and 70", in which the end 70' is fluidically connected with the compartment 18, while the end 70" is fluidically connected with the compartment 19.

In the preferred but not exclusive embodiments shown in the attached figures, upon opening the closing element D, the slider 50 may force the working fluid to flow from the compartment 19 to the compartment 18 exclusively through the circuit 60, while upon closing the closing element the slider 50 forces the working fluid to flow from the compartment 18 to the compartment 19 exclusively through the circuit 70.

However, it is clear that upon opening the closing element D, the slider 50 may force the working fluid to flow from the compartment 18 to the compartment 19exclusively through the circuit 60 or 70, while upon closing the closing element the slider 50 may force the working fluid to flow from the compartment 19 to the compartment 18 exclusively through the circuit 70 or 60, without departing from the scope of protection of the attached claims.

In order to ensure the exclusive flow of the working fluid through the circuit 60 during the opening of the closing element D, the former may be provided with check valve means 61 configured to make the circuit 60 always open from the compartment 19 to the compartment 18 and closed from the compartment 18 to the compartment 19.

However, it is clear that also the contrary may occur, without departing from the scope of protection of the attached claims.

At the same time, in order to ensure the exclusive flow of the working fluid through the circuit 70 during the closing of the closing element D, the former may be provided with check valve means 71 configured to make the circuit 70 always open from the compartment 18 to the compartment 19 and closed from the compartment 19 to the compartment 18.

In a preferred but non-exclusive embodiment, the valve means 61, 71 may be symmetrical with respect to the median plane nM of the hinge body 11, perpendicular to the axis Y.

Even more specifically, the circuit 60 may include a seat 62 for the valve means 61 at the end 60', while the end 60" may be without valve means.

Such seat 62 may have a diameter larger than that of the remaining portion of the circuit 60 so as to define an annular step 62'.

In other words, the annular step 62' may extend along a direction perpendicular to the axis Y.

Suitably, the valve means 61 may include an internally perforated manifold 63 fixed in the seat 62 and an obturator 64 movable parallel to the axis Y between the step 62', therefore defining an abutment surface 62', and the manifold 63.

Suitably, the seat 62 may include an inner lateral surface 62" which includes a threaded portion 620.

On the other hand, the manifold 63 may include an outer lateral surface 630 with a counter-threaded portion 6300 which can be screwed - in a per se known manner - to the threaded portion 620 of the surface 62".

Advantageously, the manifold 63 may include a head 63", for example flanged, arranged facing the pin 21 and an end wall 63' arranged facing the obturator 64.

Preferably, the obturator 64 may be internally hollow and it may include a closed bottom wall 64' arranged facing the abutment surface 62', a side wall 64" with one or more openings 640 and an opening 6400 arranged facing the end wall 63'.

It is clear that the translation of the shutter 64 will be due to the movement of the working fluid in the circuit 60.

Specifically, upon opening the door, the working fluid may flow through the circuit 60 from the end 60" to the end 60'.

In this manner, the obturator 64 will impact the manifold 63, ensuring an interspace for the through-flow of the working fluid between the bottom wall 64' and the abutment wall 62'.

As a result, the working fluid may flow into the seat 62, into the hole of the manifold 63, as well as reach the compartment 18.

Vice versa, upon closing the closing element D, the working fluid will flow through the space inside the manifold 63 to push the obturator 64 to impact the abutment surface 62'.

The working fluid present in the cavity of the obturator 64 may therefore flow out from the side openings 640 to return to the compartment 18.

On the other hand, the circuit 70 may include a seat 72 for the valve means 71 at the end 70", while the end 70' may be without valve means.

Such seat 72 may have a diameter larger than that of the remaining portion of the circuit 70 so as to define an annular step 72'.

Also in this case, the annular step 72' may extend along a direction perpendicular to the axis Y.

Suitably, the valve means 71 may include an internally perforated manifold 73 fixed in the seat 71 and an obturator 74 movable parallel to the axis Y between the step 72', therefore defining an abutment surface 72', and the manifold 73.

Suitably, the seat 72 may include an inner lateral surface 72" with an abutment step 720.

Suitably, the manifold 73 may include a head 73" with an upper surface 730' in contact with the wall 82 and a lateral surface 730" which has an abutment step 7300 interacting with the step 720.

In this manner, the manifold 73 may be fixed in the seat 72.

Preferably, the head 73" may include a housing adapted to interact with a common screwdriver to facilitate the insertion of the manifold 73 into the seat 72.

On the other hand, the manifold 73 may include an end wall 73'arranged facing the obturator 74.

Furthermore, the portion 110 of the end 11' of the hinge body 11 may include a pocket 111 to allow the through-flow of the working fluid between the compartment 19, the hydraulic circuit 70 and said first and/or second valve seat 62, 72.

Preferably, the obturator 74 may be internally hollow and it may include bottom wall 74' arranged facing the abutment surface 72', a side wall 74" with one or more openings 740 and an opening 7400 arranged facing the end wall 73'.

It is clear that also the translation of the obturator 74 will be due to the movement of the working fluid in the circuit 70.

Specifically, upon closing the door, the working fluid may flow through the circuit 70 from the end 70' to the end 70".

In this manner, the obturator 74 will impact the manifold 73, ensuring an interspace for the through-flow of the working fluid between the bottom wall 74' and the abutment wall 72'.

In this manner, the working fluid may flow into the seat 72, into the hole of the manifold 73, as well as reach the compartment 19.

On the other hand, upon opening the closing element D, the working fluid will flow through the space inside the manifold 73 to push the obturator 74 to impact the abutment surface 72'.

The working fluid present in the cavity of the obturator 74 may therefore flow out from the side openings 740 to return to the compartment 19.

Advantageously, there may be provided for means for adjusting the flow of the working fluid.

Such means may include grooves 16 and 17 which may extend perpendicularly to the axis Y and they may respectively intersect the circuit 60 and the circuit 70.

In order to adjust the through-flow section thereof, the flow adjustment means may include adjustment elements 160, 170, for example common adjustment screws of the to the prior art.

It is clear that such adjustment elements 160, 170 may be inserted perpendicularly to the axis Y, along the grooves 16 and 17 to intersect respective axis 60 and 70 so as to adjust the through-flow section of the circuits 60 and 70 independently with respect to each other, so as to adjust the through-flow rate of the working fluid through the two circuits.

Therefore, it is clear that the opening and closing speed may be equal or different from each other.

It is clear that the hinge 1 described heretofore may include or not include the anti- slip-off system 2 as described above.

Therefore, should the hinge 1 include the anti-slip-off system 2, the latter may be an aspect of the invention relating to the hinge 1.

Vice versa, should the hinge 1 not include the anti-slip-off system 2, the latter may be an invention independent therefrom.

In this latter case, the anti-slip-off system 2 may be suitable to be used in a hinge having the characteristics described herein in relation to the hinge 1 or in any hinge for the controlled rotary movement of a closing element having a hinge body with a cylindrical shaped seat defining an axis and a side wall with at least one threaded portion.

In light of the above, it is clear that the hinge according to the invention attains the pre-set objectives.

The hinge according to the invention is susceptible to numerous modifications and variants all falling within the inventive concept outlined in the attached claims. All details can be replaced by other technically equivalent elements, and the materials can be different depending on the technical needs, without departing from the scope of protection of the invention.

Even though the hinge has been described with reference to the attached figures, the reference numbers utilised in the description and in the claims are meant for improving the intelligibility of the invention and thus do not limit the claimed scope of protection in any manner whatsoever.
