Detailed description of a preferred embodiment

With reference to the cited figures, an embodiment of a hydraulic hinge 1 is illustrated for closing a closing element, such as for example a door, a leaf or the like, preferably made of glass, in particular glass doors of the frameless type .

Even if in the continuation it will be described? a hydraulic closing hinge, it is understood that the hinge of the present invention could also be a control hinge, that is? be devoid of one or more closing springs, cos? how can i be hydraulic or mechanical, without thereby leaving the scope of protection of the attached claims.

A control hinge can be hydraulic or mechanical, and could? or less be equipped with a reset spring and/or means of cushioning in closing and/or opening, for example one or more? elements in polymeric or elastomeric material, and/or braking means acting for example by friction.

The closing element can be anchored to a stationary support structure, for example of the vertical type such as for example a glass or plasterboard wall or a door frame, or of the horizontal type, such as a floor.

Even if frameless glass doors and a vertical wall as a stationary support will be considered hereinafter, it is however understood that other types of closing elements and stationary supports may be considered without thereby departing from the scope of protection of the attached claims.

Given that the stationary support structure and the closing element are in themselves? known, have not been illustrated in the accompanying figures.

The present invention could include various similar or equal parts and/or elements. 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.

Hinge 1 can comprise a fixed element 2 which can be anchored to the wall and a mobile element 3 which can be anchored to the door.

According to a preferred but not exclusive embodiment, the fixed element 2 can include a hinge body 2?, while the mobile element 3 can? include a 10 pin.

However, it is understood that it may the opposite also occurs without thereby leaving the scope of protection of the attached claims.

Preferably, the? fixed element 2 will be able? be defined by a base 7 that can be applied to the wall by means of screws 8 to be inserted in special holes, while the mobile element 3 can? in turn comprising two cheeks 9 to be tightened together by means of suitable screws.

Conveniently, the pin 10 and the hinge body 2? they will be able to rotate around an X axis between an open and closed position.

Advantageously, the pin 10 will be able have a pair of ends? 13?, 13?? opposite and which can be coupled to the door by means of the cheeks 9 and a central operative portion 14 interposed between these.

This central operative portion 14 will be able to include a shaped area 11 with a side surface 110.

The latter can include a curved portion 111, an opposite flat portion 113, and a pair of corner recesses 112? and 112??, each placed between the two aforementioned surfaces.

Scans 112? and 112?? will they be able to include a respective internal surface 1121? and 1121?? essentially semi-spherical.

In addition, the pin 10 will be able to include a pair of swivel elements 12? and 12?? inserted in the corner scans 112? and 112??, for example leaning against the surfaces 1121? and 1121??.

In particular, the elements 12? and 12?? will they be able to rotate together around the X axis, while will they be able to rotate one independently of the other around their respective X axes? and X?? passing through the center C?, C?? of the same, how will it come? more explained in detail later.

Advantageously, the surfaces 1121? and 1121?? may respectively include a boss 1122? and 1122??, identified along the edge of the same scans 112? and 112??, in order to prevent the elements 12? and 12?? during movement of the door, in particular when the latter rotate idly or in any case are not in contact with the surface 212.

In other words, the surfaces 1121? and 1121?? will be able to extend for at least half? of the surface of the elements 12? and 12?? in order to limit its leakage from the 112 offices? and 112?? when pin 10 and hinge body 2? they will rotate around the X axis as described below.

Fittingly, the elements 12? and 12?? may they include a respective outer surface 120? and 120??.

In particular, when the elements 12? and 12?? will they be included in scans 112? and 112??, potr? be identified a distance d1, defined between the portions 1200? and 1200?? externally identified with respect to the 112 scans? and 112??, as particularly evident in FIG.5.

Preferably, the pin 10 will be able to be symmetrical with respect to a median plane ?10 on which the X axis lies and with respect to which the X?, X?? they are parallel.

According to a preferred but not exclusive embodiment, the elements 12? and 12?? they could be a pair of pins, preferably made of metallic material and commonly known, which could help to contain the costs of the hinge 1 itself.

On the other hand, the hinge body 2? can I include a slider 20 sliding along a Y axis incident with respect to the X axis.

Preferably, the X axis and the Y axis can be perpendicular to each other, as particularly illustrated in the attached figures.

In particular, cursor 20 could include a cylindrical wall 22 with an end wall? 23 which ? integrally connected to an annular element 21, defining a through seat 213 for the pin 10.

The element 21 and the wall 23 can be made in one piece.

According to a preferred but not exclusive embodiment, the annular element 21 can have a triangle shape in plan view, especially a shield shape.

Consequently, the annular element 21 itself can include a flat wall 210 connected with the wall 23 or could? be a portion of the latter, and a substantially "U" curved wall 211.

However, it is understood that the annular element 21 could have any other form without thereby departing from the scope of protection of the attached claims.

Preferably, the annular element 21 can be symmetrical with respect to a median plane ?21 on which the Y axis lies.

In addition, the annular element 21 could include an internal surface 212 which delimits a through annular seat 213.

In essence, the surface 212 potr? define a closed path.

Conveniently, the through annular seat 213 can house the operating portion 14 of the pin 10.

Pi? in particular, the surface 212 potr? completely surround the latter in such a way that the portion 14 is completely contained within the seat 213.

Advantageously, the internal surface 212 can include two ends? 212? and 212?? opposite with respect to the Y axis, in correspondence with the wall 210.

Also, the internal surface 212 will be able to include two ends? 221? and 221?? opposite and defined along the Y axis, where the extremity? 221?? ? at wall 210.

Preferably, the extremities? 212? and 212?? will have a distance d2 equal to the distance d1, while the extremities? 221? and 221?? they may have a distance d3 greater or slightly greater than the latter.

In fact, at the end? 221?? can I can a recess 25 be made with dimensions suitable for at least partially accommodating the plug 12? or 12??, as evident in FIG.6B.

Furthermore, the scansion 25 potr? include side block portions 26 which will be able to prevent pin 12 from coming out? or 12?? from the recess 25, or they will be able to prevent it from being exceeded during the movement of the pin 10 and of the hinge body 2?, as better explained below.

From an operational point of view, the pin 10 potr? be inserted in the annular seat 213 of the annular element 21 positioned inside a cylindrical seat 4 of the hinge body 2?.

In this way, the hinge 1 will be able to be extremely compact.

In particular, the central portion 14 of the pin 10 will be facing the surface 212 of the annular element 21.

Also, the plugs 12? and 12?? can they be included in scans 112? and 112?? in such a way that everything can be assembled ?in a package?.

even more in particular, the surface 212 potr? define a substantially circular path, which can be traversed by the pins 12? and 12?? to allow the reciprocal movement of the pin 10 and of the hinge body 2?.

It is understood, therefore, that the annular element 21 could act as a cam, while the shaped portion 11 will be able to act as a follower.

In fact, the same annular element 21 could transforming the circular motion of the pin 10 into a rectilinear motion of the slider 20 in the manner described below.

It is also understood that the continuous contact of the cam and cam follower elements could favor a complete control of the movement of the pin 10 and of the hinge body 2?.

In particular, the hinge body 2? can I include an internal wall 200 that could? define a working chamber 6 with a working fluid, for example oil, within which it can? scroll the cursor 20.

Wall 23 will be able dividing the working chamber 6 into two compartments 61 and 62 with variable volume and fluidly communicating, where the compartment 62 contains the cam elements 21 and cam followers 11.

For the purpose, can be provided a valve 24 mounted in the slider 20 and could? allow the passage of the oil from the first compartment 61 to the second compartment 62 during the opening of the door and prevent it from flowing back during the closing of the same.

In other words, hinge 1 will be able to be of the hydraulic type, with operation in s? known, where the return of?oil from the compartment 62 to the compartment 61 potr? take place via a dedicated circuit.

In this way, the transition from open to closed position will be? damped and controlled to prevent possible damage to the door.

Furthermore, according to a preferred but not exclusive embodiment, the compartment 61 can include contrasting elastic means 5, for example a closing spring 51 or a closing spring 51 and a reset spring 52, so as to make the passage from the open to the closed position automatic and controlled.

Even if in the continuation of the description it will be considered? the hinge 1 in the form of a hydraulic hinge with contrast means 5, in particular two springs 51 and 52, however it is understood that the hinge 1 will be able to even be without it without thereby leaving the scope of protection of the attached claims.

With particular reference to FIGS. 6A to 6E, different positions of the pins 12 will be described below? and 12?? along the path defined by the wall 212 during the movement of the pin 10 and of the hinge body 2? around the X axis.

In particular, at the positions shown in FIGS. 6A, 6B, 6C and 6D, on the closing element can? do not act on any unwanted external load, such as for example a gust of wind, forced closing and/or opening by an inattentive user or the like.

On the other hand, at the position shown in FIG. 6E, on the closing element can? act the aforementioned unwanted external load.

In the closed position, particularly evident in FIG. 6A, plugs 12? and 12?? could they both be in contact with two contact surfaces 212? and 212??, i.e. the portions 1200? and 1200?? will they be in contact with the latter at a respective point of tangency P? and P??.

It is therefore understood that the portions of? extremity? 212? and 212?? could they include the same contact surfaces 212? and 212??.

This position can be identified as zero position.

In particular, the plugs 12? and 12?? they will be able to exert an equal and opposite force to that exerted by the springs 51 and 52 which will push the slider 20 so that the wall 211 of the annular element 21 is in full contact with the wall 200.

Following the action of a user on the door, pin 10 will be able to rotate around the X axis up to a position, illustrated in FIG. 6B, opening 90? approximately with respect to the closed position, in correspondence with which one of the two pins 12? or 12?? you can insert at least partially in the scansion 25, while the other can? move away for an infinitesimal distance from the wall 112 to rotate in an idle manner before reaching stasis.

It is understood, therefore, that plug 12? or 12?? and the wall 112 will come into contact at a single point of tangency P?, for example at a contact surface 221??.

It is therefore understood that the portion d? extremity? 221?? can I include the contact surface 221??.

Although in FIG. 6B ? highlighted in particular the?insertion of plug 12?? in the scansion 25, however, it is understood that it could? also happen the opposite, or the latter? potr? accommodate the 12? plug.

Indeed, in an extremely advantageous way, the hinge 1 can be of the ambidextrous type, since the symmetry of the annular element 21 and of the pin 10 will allow the door to be opened both to the right and to the left.

With particular reference to FIG. 6C, does the path taken by the pins 12 show? and 12?? during the transition from the open position to the closed position where, under the thrust of the springs 51 and 52, they can return to the zero position.

In particular, one of the two plugs may be pushed against the wall 212 at the point of tangency P?, while the other one could? rotate idly and be held in place by the respective holding protrusion 1122? or 1122??.

In FIG. 6D ? an operational lockout position is shown. In particular, when a user will attempt? to further open the door, plug 12? or 12?? can I be pushed by the cam 21 against the block portion 26 which will not allow? overcoming it.

In particular, the? opening potr? be 95? - 100? compared to zero.

If so, both plugs 12? or 12?? will they be in contact with the surface 212, for example the pin 12?? at surface 221?? at point P? and plug 12? at the surface 212 at the point P<IV>.

A last configuration, particularly illustrated in FIG. 6E, can I correspond to an attempted forced closing of the door.

In this case, the pin in contact with the surface 212 during the entire movement of the pin 10, can? move away from the same surface 212, while the other spine will be able to? make contact at the point of tangency P<???>.

Thus, the contact between the surface 212 and the pin 12? can I act as a mechanical brake on the reciprocal movement of the pin 10 and of the hinge body 2?.

In addition, in the event of forcing the door from the open position to the closed position, it may be provided an overpressure valve 30, in itself? known, with a respective hydraulic circuit, so as to allow a further passage of the oil from the compartment 62 to the compartment 61, facilitating its return and preventing possible damage to the door.

It is understood, therefore, that the inner surface 212 could include a plurality? of intermediate portions 2000 on which the plugs 12? and 12?? they will be able to scroll.

The intermediate portions 2000 can be interposed between the end portions 212?, 212??, 221?, 221?? and may include the points of tangency P?, P??, P???, P<IV>.

From what has been described above, it is evident that the hinge according to the invention achieves the intended aims, and in particular that of guaranteeing a controlled movement of the door both in opening and in closing, thus to ensure l?integrit? and its long duration.

Furthermore, this hinge can achieve all the pre-established purposes with minimum overall dimensions and a limited number of constituent parts.

The hinge according to the invention ? susceptible to numerous modifications and variations, all of which are within the scope of the inventive concept expressed in the attached claims. All the details may be replaced by other technically equivalent elements and the materials may be different according to requirements, without departing from the scope of the invention, as defined in the attached claims.

Even if the zipper? been described with particular reference to the accompanying figures, the reference numbers used in the description and in the claims are used to improve understanding of the invention and do not constitute any limitation to the claimed scope of protection.
