Description

SYSTEM FOR REDUCING THE CLOSING AND/OR OPENING SPEED OF REVOLVING OR TRANSLATABLE ELEMENTS.

TECHNICAL FIELD OF THE INVENTION

The present invention concerns the field of speed reducing systems. More particularly, the present invention concerns the field of systems for reducing the opening and/or closing speed of revolving or translatable elements, for example door leaves, panels of windows and of furnishing elements.

PRIOR ART

It is known that several devices available on the market can be used in order to reduce the opening and/or closing speed of a door or a window and at the same time avoid opening and/or closing the same abruptly.

The devices of known type, however, pose some drawbacks. They are often very cumbersome, noisy during use, hard to open, difficult to assemble and unreliable. Furthermore, their mechanical structure is often complicated and therefore they are expensive to produce. An example of a device of this type is disclosed in the Italian Patent Application no. VI2006A000216.

It is therefore the object of the present invention to provide a system for reducing the closing and/or opening speed of revolving or translatable elements, such as door leaves, panels of windows, of pieces of furniture, furnishing elements or similar elements, which at least partially solves the above mentioned problems. In particular, it is the object of the present invention to provide a silent system, easy to make, economical to produce, with reduced size and therefore suited to be applied also in the cases in which there are problems of space, while at the same time being reliable.

It is furthermore the object of the present invention to provide a system that can be easily adapted to different types of revolving or translatable elements with different needs in terms of use.

Finally, it is the object of the present invention to provide a system that does not require frequent maintenance and is such that maintenance procedures are easy, rapid and inexpensive.

SUMMARY OF THE INVENTION

The present invention is based on the new and inventive idea of providing a system for reducing the opening and/or closing speed of revolving and translatable elements like doors, windows, pieces of furniture or similar elements, both revolving and sliding, comprising a housing chamber and a movable element suited to move inside the housing chamber in such a way that the movement of the movable element inside the housing chamber is slowed down by a viscous fluid contained in the system.

The invention provides a system for reducing the closing and/or opening speed of revolving or translatable elements, for example door leaves, panels of windows or of furnishing elements, comprising a first element provided with a housing chamber and a movable element suited to move inside the housing chamber; the first element comprising connection means connected to the movable element in such a way that the movement of the revolving or translatable element causes the relative movement of the connection means and the movable element, in such a way that the movable element moves inside the housing chamber; the system being such that the housing chamber and the movable element are configured so that they define a circulation area suited to allow the circulation of a fluid, and such that the movement of the movable element inside the housing chamber is slowed down by the fluid. The fluid can be a gas, for example air, or a viscous fluid, for example oil or similar substances. The speed reducing system created in this way is silent, small-sized, easy to produce and economical.

According to an embodiment of the present invention, the same provides a system for reducing the closing and/or opening speed of revolving or translatable elements, such as doors, suited to be mounted on a door frame and comprising a first element suited to be mounted on the door leaf; the first element being provided with a housing chamber and a movable element suited to move inside the housing chamber; the first element comprising connection means suited to connect the door leaf to the movable element, in such a way that when the door leaf is connected to the movable element through the connection means the movement of the door leaf causes the movement of the movable element inside the housing chamber; the system being such that the housing chamber and the movable element are configured so that they define a circulation area suited to allow the circulation of a viscous fluid, for example oil, inside it, and such that the movement of the movable element inside the housing chamber is slowed down by the viscous fluid.

According to a further embodiment of the present invention, the same provides a system that is such that the size and/or the shape of the circulation area are variable, in such a way as to adjust the slow-down action exerted by the system on the revolving element. In this way the system can be easily adapted to different types of doors used for different purposes.

According to a further embodiment of the present invention, the same provides a system that is such that the movable element and/or the housing chamber comprise one or more drawn elements.

The movable element and the housing chamber can therefore comprises one or more drawn elements that may comprise rings, elastic rubber elements, bars, traces, grooves or similar elements applied to or made on the inner wall of the housing chamber and/or on the walls of the movable clement facing towards the housing chamber. In this way, the one or more drawn elements can determine the shape and/or the size of the circulation area. If the drawn elements are also made in such a way that their size can vary when a force is applied to them, then they can not only determine the shape and/or the size of the circulation area, but also vary them. The speed reducing system comprising one or more drawn elements is, therefore, easily adaptable to different types of revolving or translatable elements to be used for different purposes.

According to a further embodiment of the present invention, the same provides a system that is such that the movable element and the connection means are coupled through a cam system. In this way, the rotation or translation movement of the revolving element is easily transformed into a translation of the movable element of the system.

According to a further embodiment of the present invention, the same provides a system that is such that the connection means comprise a connecting rod system. Also in this case, the rotation or translation movement of the revolving element is easily transformed into a translation of the movable element of the system.

According to a further embodiment of the present invention, the same provides a system that is such that the movable element moves inside the housing chamber perpendicularly to the rotation axis or to the direction of translation of the revolving or translatable element.

According to a further embodiment of the present invention, the same provides a system that is such that the movable element moves inside the housing chamber parallel to the rotation axis or to the direction of translation of the revolving or translatable element.

According to a further embodiment of the present invention, the same provides a system that is such that the movable element rotates inside the housing chamber. According to a further embodiment of the present invention, the same provides a system that is such as to comprise a second element and/or assembly means suited to complete the assembly of the system.

According to a further embodiment of the present invention, the same provides a system that is such as to comprise one or more O rings suited to seal the viscous fluid inside the system.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is described here below with reference to particular embodiments, as illustrated in the attached drawings. However, the present invention is not limited to the particular embodiments illustrated in the following detailed description and represented in the figures, rather, the embodiments described herein simply exemplify the various aspects of the present invention, the scope of which is defined in the claims. Further modifications and variants of the present invention will be clear to the expert in the art.

Figure 1A schematically shows an exploded 3D view of a system for reducing the closing and/or opening speed of revolving or translatable elements according to an embodiment of the present invention. The revolving or translatable element can be, for example, a door leaf, the panel of a window, of a piece of furniture or of a furnishing element .

The system is suited to be mounted on the frame of the revolving or translatable element, for example the frame T of a door or of a window, or the bearing structure of a piece of furniture, and comprises a first element 1 made in any suitable material, for example metal, plastic, a combination of the same or similar materials.

For the sake of simplicity, in the following description reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements that is mounted on a revolving element, wherein the revolving element is a door leaf and the bearing structure is the door frame T. It is clear, however, that the description provided herein is valid also in the case where the revolving or translatable element is the panel of a window, of a piece of furniture or the like, and the bearing structure is the frame of a window or the bearing structure of a piece of furniture or a similar element.

The first element 1 comprises a housing chamber 4 and a movable element 3 suited to move inside the housing chamber 4. The movable element 3 can slide inside the housing chamber parallel to the axis of symmetry X of the housing chamber 4. In fact, the length of the movable element 3, meaning its extension along the axis X, is smaller than the length of the housing chamber 4. For this reason, the movable element 3 defines, inside the housing chamber 4, two translation areas 16a and 16b (clearly visible, for example, in Figure 2E) defined as areas of the housing chamber 4 not occupied by the movable element 3. The size and the position of the translation areas 16a and 16b depend, as is clearly shown in the figure, on the position of the movable element 3 inside the housing chamber 4. The difference in size between the movable element 3 and the housing chamber 4 along the axis X can also determine the maximum opening angle of the door leaf A. More particularly, the movable element 3 and the housing chamber 4 can have such a size as to allow a clockwise and/or counterclockwise rotation of the door leaf A by an angle included between 0° and 180°. According to the embodiment shown in the figure, the movable element 3 and the housing chamber 4 are cylindrical in shape, but they can be in any suitable shape, for example the shape of a cube, a parallelepiped, or a similar shape.

The first element 1 furthermore comprises connection means 5 suited to connect the door leaf A to the movable element 3. The connection means 5 comprise, in fact, in the embodiment shown herein, a cavity 8 suited to accommodate one end of the door leaf A. The end of the door leaf A and the connection means 5 are properly fixed through fixing means 15 and the element 1 is closed through closing elements 25. The fixing means 15 can be suitable sealing rings, hooks, a combination of the same or similar means, and the closing means 25 can be, for example, a metal bushing or similar means. The connection means 5 are inserted in the first element 1 in such a way that they can rotate inside it. The connection means 5 are positioned parallel to the rotation axis Y of the door leaf A, which in this embodiment of the invention is perpendicular to the axis of symmetry X of the housing chamber 4. When the door leaf A rotates around the axis Y to bring the door from an open configuration to a closed configuration and vice versa, the connection means 5 move integrally with it. In the embodiment of the invention shown herein, the connection means 5 are in a cylindrical shape, too, with central axis corresponding to the rotation axis Y of the door leaf A, but they can be in any other suitable shape. The portion of the connection means 5 opposite the cavity 8 and completely inserted in the first element 1 of the system comprises a first component 12a of a cam system. According to the embodiment shown herein, the first component 12a of the cam system consists of a cylinder, decentered with respect to the rotation axis Y of the door leaf A. The first component 12a of the cam system is suited to be at least partially inserted in the housing chamber 4. The movable element 3 comprises the second component 12b of the cam system. More particularly, in the embodiment shown herein, the second component 12b of the cam system comprises a recess suited to accommodate the first component 12a of the cam system of the connection means 5. More particularly, the profile of the first component 12a is made in such a way that it can be inserted in the second component 12b of the cam system. Therefore, when the system is assembled, both the movable element 3 and the portion of the connection means 5 opposite the cavity 8 are inside the housing chamber 4 and are positioned in such a way that the first component 12a of the cam system of the connection means 5 is properly inserted in the second component 12b of the cam system of the movable element 3. In this way, when the door leaf A is connected to the movable element 3 through the connection means 5, the rotation of the door leaf A causes the rotation of the connection means 5 around the axis Y, in particular the rotation of the first component 12a of the cam and thus the movement of the movable element 3 inside the housing chamber 4 (the dynamics of these movements is described more clearly with reference, for example, to Figures from 2A to 2E). When, as in the case illustrated in the figure, a cam system is used to transform a rotary movement into a linear movement, at the beginning the speed at which the door leaf can rotate is higher and successively it tends to decrease. This is due to the fact that the movable element 3 covers a longer linear path.

The first element 1 of the system and more particularly the housing chamber 4 and the portion of the element 1 that houses the connection means 5 contain a viscous fluid V, for example oil or a similar substance, which at least partially fills them up. The fluid F is sealed inside the element 1 thanks to one or more O rings 13 that seal the first element 1 when the system is assembled. The one or more O rings can be made in any suitable material, for example rubber, silicone, a combination of the same or similar materials.

Furthermore, the system is such that the housing chamber 4 and the movable element 3 are configured in such a way as to define a circulation area 6 suited to allow the circulation of the viscous fluid V from a translation area 16a to the other 16b and vice versa, and such that the movement of the movable element 3 inside the housing chamber 4 is slowed down by the viscous fluid V. More particularly, according to the embodiment shown in the figure, the diameter d2 of the housing chamber 4, defined along any cross section of the housing chamber 4 along a plane perpendicular to the axis of symmetry X, is larger than the diameter dl of the movable element 3 defined along any cross section of the movable element 3 along a plane perpendicular to the axis X, in such a way that an area 6 is formed between the two, in which the viscous fluid V can circulate, moving from a translation area 16a to the other 16b, and vice versa. More particularly, the circulation area 6 is defined by the inner wall of the housing chamber 4 and the outer wall of the movable element 3.

The movable element 3 and/or the housing chamber 4 may comprise one or more drawn elements 7, obtained through a drawing process (better visible, for example, in Figure 5B or 1 1 ). The drawn elements include rings, elastic rubber elements, helical bars and/or profiles, grooves, traces, a combination of the same or similar elements. In some embodiments of the invention illustrated here below, the one or more drawn elements 7 can have variable size. The one or more drawn elements 7 can, therefore, determine the shape and/or the size of the circulation area 6. Furthermore, if the drawn elements have variable size, then they can not only determine the shape and/or the size of the circulation area, but also vary them.

The system may comprise just one first element 1 or it can furthermore comprise a second element 2. The second element 2, in the embodiment shown, serves to complete the assembly of the system. In particular, the second element 2 comprises a plate 14 with one or more holes 9. The one or more holes 9 are suited to receive the assembly means I I , for example screws, hooks, a combination of the same or similar means. The assembly means 1 1 connect the first element 1 and the second element 2 of the system in a stable and safe manner.

The element 10a is, instead, a first element of the top-up means. It may comprise a hole made in the plate 14. The viscous fluid V can be introduced through the first element 10a of the top-up means, if this is necessary after a prolonged period of use of the system. The first element 10a of the top-up means can be sealed using a second element 10b of the top-up means. The second element 10b of the top-up means can be a screw, a cap, a combination of the same or similar elements.

The door leaf A can furthermore be provided with a return system, for example a spring or similar elements, suited to bring the door leaf A back to the closed configuration of the door. In alternative embodiments of the invention, the return system can also be installed inside the housing chamber 4.

It should be finally underlined that the system can also be installed in an opposite manner than described above, that is, in such a way that the connection means are fixed to the door frame T and the element 1 is connected to the door leaf A, so that the rotation of the door leaf A causes the rotation of the housing chamber 4 and thus the relative movement of the two components 12a and 12b of the cam system.

Figure I B schematically shows a 3D view of the system shown in Figure 1A. The system is shown assembled.

The figure clearly shows the first element 1 and the second element 2 of the system, the outside of the housing chamber 4, the portion of the connection means 5 comprising the cavity 8, the closing means 25, the assembly means 1 1 and the second element of the top-up means 1 Ob.

The door frame T is mounted at the side and on top of a supporting element S, for example a wall, and under the floor P. The door leaf A is mounted on the door frame T in such a way that it rotates around the axis Y. In the configuration shown in the figure, the system is mounted on the door frame T in such a way that it is completely inserted in a suitable slit made in the floor P and that one end of the door leaf A can be inserted in the cavity 8 of the first element 1 of the system. The end of the door leaf A inserted in the cavity 8 of the first element 1 of the system is the one at the level of the rotation axis Y of the door leaf and facing towards the floor P.

Figure 2B schematically shows the system shown in Figure 2A, along the direction CC.

In the figure, it is possible to observe the supporting element S of the door, the frame T of the same and the door leaf A in the closed configuration, meaning parallel to the plane defined by the door frame T.

The figure shows the first element 1 and the second element 2 of the system. In particular, it is possible to observe the outside of the housing chamber 4 and the closing means 25 of the first element 1. It is furthermore possible to observe the plate 14, the top-up means 10b and the assembly means 1 1 of the second element

2.

In particular, it is possible to observe a sectional view of the movable element 3, a portion of the housing chamber 4, the connection means 5, the fixing means 15, the closing means 25 and the O ring 13. As regards the connection means 5, the first component 12a of the cam system and the cavity 8 are shown in the figure. Figure 2E schematically shows the system shown in Figure 2C, along the direction AA.

The figure shows the first element 1 and the second element 2 of the system. As regards the second element 2, the top-up means 10a and 1 Ob, the assembly means 1 1 and the plate 14 are visible in the figure. As regards the first element 1, it is possible to observe the housing chamber 4, the movable element 3, which defines the two translation areas 16a and 16b in the housing chamber 4, and the two components 12b and 12a of the cam system, in greater detail, respectively, the recess of the movable element 3 and the decentered cylinder of the connection means 5.

In the closed configuration of the door, the connection means 5 are in configuration of rest, meaning that they are positioned inside the first element, in such a way that the first component 12a of the cam system is completely inserted in the second component 12b of the cam system, that is, in the cavity of the movable element 3.

The structure shown in the figure is identical to that shown in Figure 2A, but in this case the door leaf A is in a possible open configuration of the door. More particularly, the door leaf A is rotated by 90° clockwise with respect to the plane defined by the door frame T.

Figure 3B schematically shows the system shown in Figure 3A, along the direction CC.

In the figure, it is possible to observe the supporting element S of the door, the frame T of the same and the door leaf A, in a position perpendicular to the plane defined by the door frame T, in a possible open configuration of the door.

In the figure it is possible to observe the first clement 1 and the second element 2 of the system. In particular, it is possible to observe the outside of the housing chamber 4 and the closing means 25 of the first element 1. Furthermore, it is possible to observe the plate 14, the top-up means 10b and the assembly means 1 1 of the second element 2.

In particular, it is possible to observe a sectional view of the movable element 3, a portion of the housing chamber 4, the connection means 5, the fixing means 15, the closing means 25 and the O ring 13. As regards the connection means 5, the first component 12a of the cam system and the cavity 8 are shown in the figure. The differences between Figure 2D and Figure 3D lie in that in Figure 3D the system is shown in a configuration corresponding to an open configuration of the door, while in Figure 2D it is shown in a configuration corresponding the closed configuration of the same. More particularly, in Figure 3D the connection means 5 that connect the door leaf A to the movable element 3 are rotated clockwise, inside the element 1 , by 90° with respect to the rest position of the system, following the rotation of the door leaf A from the configuration in which the door is closed to a possible configuration in which the door is open. The movements to which the other elements of the system are subjected can be more easily understood making reference to Figure 3E.

The figure shows the first element 1 and the second element 2 of the system. As regards the second element 2, it is possible to observe the top-up means 10a and 10b, the assembly means 1 1 and the plate 14. As regards the First element 1, it is possible to observe the housing chamber 4, the movable element 3 that defines the two translation areas 16a and 16b in the housing chamber 4, and the two components 12b and 12a of the cam system, in greater detail, respectively, the recess of the movable element 3 and the decentered cylinder of the connection means 5.

Differently from Figure 2E, where the system is shown in the rest configuration, here the system is shown in a configuration corresponding to a possible configuration in which the door is open. More particularly, the connection means 5 that connect the door leaf A to the movable element 3 are rotated clockwise, inside the element 1, by 90° with respect to the rest configuration, following the rotation of the door leaf A from the configuration in which the door is closed to a configuration in which the door is open. This implies that also the first component 12a of the cam system is rotated clockwise by 90° with respect to the rotation axis Y of the door leaf A. Considering that the first component 12a of the cam system is coupled with the second component 12b of the cam system, meaning the recess of the movable element 3, the movable element 3 translates inside the housing chamber 4. In the embodiment shown in the figure, following the rotation of the door leaf A the movable element 3 has been moved towards the translation area 16a. In this way, in this possible configuration of open door, the volume of the translation area 16a decreases, while the volume of the translation area 16b increases due to the translation of the movable element 3. During this translation movement of the movable element 3, the viscous fluid V contained in the housing chamber 4 has moved from the translation area 16a to the translation area 16b passing through the circulation area 6 included between the movable element 3 and the housing chamber 4. It is clear that the forced passage of the viscous fluid V through the circulation area 6 slows down the rotation of the door leaf A from a configuration in which the door is closed to a configuration in which the door is open and vice versa. It is also clear that by adjusting the size of the circulation area 6 it is possible to adjust the slow-down action with which the system reduces the rotation speed of the door leaf A. More particularly, increasing the size of the circulation area 6 means decreasing the slow-down action and vice versa.

Figure 4A schematically shows a door with the system shown in Figure 1A installed thereon. The door comprises a door leaf and a door frame. The door is shown along the direction perpendicular to the plane defined by the door frame. The door is shown in a further open configuration.

The structure shown in the figure is identical to that shown in Figure 2A, but in this case the door leaf A is in a further open configuration of the door. More particularly, the door leaf A is rotated counterclockwise by 90° with respect to the plane defined by the door frame T.

Figure 4B schematically shows the system shown in Figure 4A, along the direction CC.

In the figure, it is possible to observe the supporting element S of the door, the door frame T and the door leaf A, in a position perpendicular to the plane defined by the door frame T, in a further possible open configuration of the door.

The system is shown in a configuration corresponding to a further possible open configuration of the door on which the system is installed.

The figure shows the first element 1 and the second element 2 of the system. In particular, it is possible to observe the outside of the housing chamber 4 and the closing means 25 of the first element 1. Furthermore, it is possible to observe the plate 14, the top-up means 10b and the assembly means 1 1 of the second element 2.

In particular, it is possible to observe a sectional view of the movable element 3, a portion of the housing chamber 4, the connection means 5, the fixing means 15, the closing means 25 and the O ring 13. As regards the connection means 5, the first component 12a of the cam system and the cavity 8 are shown in the figure. The differences between Figure 2D and Figure 4D lie in that Figure 4D shows the system in a configuration corresponding to an open configuration of the door, while Figure 2D shows the system in a configuration corresponding to the closed configuration of the door. More particularly, in Figure 4D the connection means 5 that connect the door leaf A to the movable element 3 are rotated counterclockwise, inside the element 1 , by 90° with respect to the rest position of the system, following the rotation of the door leaf A from the configuration in which the door is closed to a further possible configuration in which the door is open. The movements to which the other elements of the system are subjected can be more easily understood making reference to Figure 4E.

Figure 4E schematically shows the system shown in Figure 4C, along the direction AA.

Differently from Figure 2E, in which the system is shown in a configuration corresponding to the closed configuration of the door, here the system is shown in a configuration corresponding to a further open configuration of the door. More particularly, the connection means 5 that connect the door leaf A to the movable element 3 are rotated counterclockwise by 90° inside the element 1, following the rotation of the door leaf A from the configuration in which the door is closed to a further configuration in which the door is open. This implies that also the first component 12a of the cam system is rotated counterclockwise, inside the element 1, by 90° with respect to the rotation axis Y of the door leaf A. Considering that the first component 12a of the cam system is coupled with the second component 12b of the cam system, meaning the recess of the movable element 3, the movable element 3 translates inside the housing chamber 4. In the embodiment shown in the figure, following the rotation of the door leaf A the movable element 3 translates towards the translation area 16b. In this way, in the open configuration of the door, the volume of the translation area 16b decreases, while the volume of the translation area 16a increases due to the translation of the movable element 3. During this translation movement of the movable element 3, the viscous fluid V contained in the housing chamber 4 moves from the translation area 16b to the translation area 16a passing through the circulation area 6 included between the movable element 3 and the housing chamber 4. It is clear that the forced passage of the viscous fluid V through the circulation area 6 causes a slowdown in the rotation the door leaf A performs to pass from a configuration in which the door is closed to a configuration in which the door is open and vice versa. It is also clear that by adjusting the size of the circulation area 6 it is possible to adjust the slow-down action with which the system reduces the rotation speed of the door leaf A. More particularly, increasing the size of the circulation area 6 means decreasing the slow-down action and vice versa.

According to the embodiment shown in the figure, the drawn elements 7 comprise a ring 17, interrupted by a tubular element 18 made of an elastic material. The ring 17 can be made in any suitable material, like for example metal, plastic, a combination of the same or similar materials. The tubular element made of an elastic material can be in rubber, silicone, a combination of the same or similar materials. The ring 17 is made in such a way that its side walls 19 are not perpendicular to the internal and external walls of the ring 17 itself, but in such a way that the former are inclined with respect to the latter. The ring 17, furthermore, is made in such a way that by applying a force to the inclined walls 19 it is possible to reduce the inner diameter d3 of the ring 17, thanks to the compression of the tubular element made of an elastic material 18. The bottom panels in the figure show the ring 17 in position of balance (left bottom panel) and in position of compression (right bottom panel). The inner diameter d3 of the ring 17 in position of balance is larger than the diameter d3 ' of the ring in position of compression.

Figure 5B schematically shows a 3D view of a system for reducing the closing and/or opening speed of revolving or translatable elements according to a further embodiment of the present invention. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can also be used in the case where the revolving or translatable element is the panel of a window or of a piece of furniture or of similar elements and the bearing structure is a window frame or the bearing structure of a piece of furniture or similar elements.

The figure shows the system comprising, furthermore, the drawn element 7 of the ring type 7, shown in Figure 5 A, in which the plate 14 of the second element 2 of the system furthermore comprises a projecting element 20. The projecting element 20 is in the shape of a cylinder and the part of the end not connected to the plate 14 can be inclined, with respect to the plate 14, by an angle equal to the inclination of the side walls 1 of the ring 17.

When the system is assembled, the drawn element 7 is applied to the end of the movable element 3 that is directed towards the second element 2 of the system and the projecting element 20 rests on the side walls 19 of the ring 17. In this way, by using the assembly means 1 1, more precisely by tightening or loosening them, it is possible to vary the force with which the projecting element 20 pushes the side walls 19 of the ring 17, so as to vary its inner diameter d3. In this way, it is also possible to vary the size of the circulation area 6 and thus to vary the slow-down action exerted by the system.

Figure 6A schematically shows a sectional view of the system shown in Figure 5B, along a plane perpendicular to the rotation axis of the revolving element. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can also be used in the case where the revolving or translatable element is the panel of a window or of a piece of furniture or of similar elements and the bearing structure is a window frame or the bearing structure of a piece of furniture or similar elements.

The figure shows the first element 1 and the second element 2 of the system. More particularly, as regards the first element 1, it is possible to observe the movable element 3, the housing chamber 4, the first component 12a and the second component 12b of the cam system, the translation areas 16a and 16b, the circulation area 6 and the ring 17. As regards the second element 2, it is possible to observe the plate 14, the top-up means 10b, the fixing means 1 1 and the projecting element 20.

In the configuration shown in the figure, the ring 17 is positioned around the movable element 3, at one of its ends, more particularly at the end of the movable element 3 directed towards the second element 2 of the system. In this position, the ring 17 determines the size of the circulation area 6 as, in the configuration in which the system is assembled, it is positioned between the movable element 3 and the internal wall of the housing chamber 4. More particularly, in the configuration shown in the figure, the portion of the circulation area 6 that is nearest to the second element 2 of the system is formed by the movable element 3 and the internal wall of the ring 17. In the figure, the projecting element 20 of the second element 2 is shown partially inserted in the first element 1. In this position, the inclined wall of the end of the projecting element 20 not fixed to the plate 14 does not rest on the inclined walls 19 of the ring 17. The ring 17 is, therefore, in position of balance. In this position, the inner diameter d3 of the ring 17 is as large as possible and consequently the system is in a configuration in which the circulation area 6 is as large as possible, and thus, if the door leaf A is brought from an open to a closed configuration of the door, the slow-down effect generated by the passage of the viscous fluid V through the circulation area 6 is as limited as possible.

The projecting element 20 of the second element 2 is shown, in the figure, further inserted in the first element 1. The movement of the second element 2 towards the first element 1 is obtained, for example, by further tightening the assembly elements 1 3 , for example screws or similar elements. In this position, the inclined wall of the end of the projecting element 20 not fixed to the plate 14 rests on the inclined side wall 19 of the ring 17 facing towards the second element 2 of the system, and thus exerts a force F^' on it. The ring 17 is thus in a first position of compression. In this position, the inner diameter d3 ' of the ring 17 is smaller than the inner diameter d3 of the ring 17 in position of balance. Consequently, the system is in a configuration in which the circulation area 6 is smaller than in the configuration in which the ring 17 is in position of balance, and therefore, in the case where the door leaf A is brought from a configuration in which the door is open to a configuration in which the door is closed and vice versa, the slow-down effect generated by the passage of the viscous fluid V through the circulation area 6 is greater than in the case where the ring 17 is in position of balance.

Figure 6C schematically shows the system shown in Figure 6 A, in a further configuration of the system.

The projecting element 20 of the second element 2 is shown, in the figure, further inserted in the first element 1. The movement of the second element 2 towards the first element 1 can be obtained, for example, by further tightening the assembly elements 1 1 , for example screws or similar elements. In this position, the inclined wall of the end of the projecting element 20 not fixed to the plate 14 rests on the inclined side wall 19 of the ring 17 facing towards the second element 2 of the system, and thus exerts on it a force F" that exceeds F\ The ring 17 is thus in a second position of compression. In this position, the inner diameter d3 " of the ring 17 is smaller than the inner diameter d3 of the ring 17 in position of balance, and smaller than the diameter d3 ' of the ring 17 in the first position of compression. Consequentiy, the system is in a configuration in which the circulation area 6 is even smaller compared to the configurations in which the ring 17 is in position of balance and in which the ring 17 is in the first position of compression, and therefore, in the case where the door leaf A is brought from a configuration in which the door is open to a configuration in which the door is closed and vice versa, the slow-down effect generated by the passage of the liquid through the circulation area 6 is greater than in the case where the ring 17 is in condition of balance or in the first position of compression.

According to the embodiment of the invention shown in the figure, the drawn elements 7 comprise an elastic ring 21a, provided with two circular elements respectively connected to each other along one of their circumferences. The elastic ring 21a can be made in any suitable elastic material, for example rubber, plastic, a deformable metal, a combination of the same or similar elements. The elastic ring 21a is made in such a way that by applying a force to the external walls 22a it is possible to cause a compression of the ring. This compression reduces the inner diameter d4 and increases the outer diameter d5 of the elastic ring 21 a with respect to the position of balance. The left panels in the figure show the elastic ring 21a in condition of balance (in the left panel) and in position of compression (centre panel). The inner diameter d4 of the elastic ring 21 a in position of balance is larger than the diameter d4' of the elastic ring 21a in position of compression and the outer diameter d5 of the elastic ring 21a in position of balance is smaller than the diameter d5' of the elastic ring 21 a in position of compression.

Figure 7B schematically shows the system according to a further embodiment of the present invention, in a sectional view along a plane passing through the rotation axis of the revolving element. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can also be used in the case where the revolving or translatable element is the panel of a window or of a piece of furniture or of similar elements and the bearing structure is a window frame or the bearing structure of a piece of furniture or similar elements.

In the figure it is possible to observe the first element 1 and the second element 2 of the .system. More particularly, as regards the first element 1, it is possible to observe the movable element 3, the housing chamber 4, the connection means 5 comprising the first component 12a of the cam system, the translation areas 16a and 16b, the circulation area 6 and the elastic ring 21 a. As regards the second element 2, it is possible to observe the plate 14, the top-up means 10b, the assembly means 1 1 and the projecting element 20.

In the configuration shown in the figure, the elastic ring 21 a is positioned around the movable element 3, at one of its ends, more particularly at the end of the movable element 3 facing towards the second element 2 of the system. In this position, the elastic ring 21 a can determine the size of the circular area 6 as, in the configuration in which the system is assembled, it is positioned between the movable element 3 and the internal wall of the housing chamber 4. More particularly, in the configuration shown in the figure, the portion of the circulation area 6 that is nearest to the second element 2 of the system is formed by the movable element 3 and by the internal wall of the elastic ring 21a. In the figure, the projecting element 20 of the second element 2 is shown partially inserted in the first element 1. In this position, the wall of the end of the projecting element 20 not fixed to the plate 14 rests on the side wall 22a of the elastic ring 21a facing towards the element 2 and thus exerts a force F^' on it. The elastic ring 21 a is thus in a first position of compression. In this position, the inner diameter d4' of the elastic ring 21 a is smaller than the inner diameter d4 of the elastic ring 21a in position of balance. Consequently, the system is in a configuration in which the circulation area 6 is smaller compared to the configuration in which the elastic ring 21a is in position of balance. Therefore, in the case where the door leaf A is brought from a configuration in which the door is open to a configuration in which the door is closed and vice versa, the slowdown effect generated by the passage of the viscous fluid V through the circulation area 6 is greater than in the case where the elastic ring 21a is in position of balance.

The system shown is identical to the system shown in Figure 7B, but in this case the projecting element 20 of the second element 2 is shown, in the figure, further inserted in the first element 1. In this position, the wall of the end of the projecting element 20 not fixed to the plate 14 rests on the side wall 22a of the elastic ring 21a facing towards the second element 2 of the system, and thus exerts on it a force F" that exceeds F'. The elastic ring 21a is, therefore, in a second position of compression. In this position, the inner diameter d4 " of the elastic ring 21 a is smaller than the inner diameter d4 of the elastic ring in position of balance, and smaller than the inner diameter d4^' of the elastic ring 21a in the first position of compression. Consequently, the system is in a configuration in which the circulation area 6 is even smaller compared to the configurations in which the elastic ring 21a is in position of balance and in which the elastic ring 21 is in the first position of compression. Therefore, in the case where the door leaf A is brought from a configuration in which the door is open to a configuration in which the door is closed and vice versa, the slow-down effect generated by the passage of the viscous liquid V through the circulation area 6 is greater than in the case where the elastic ring 21a is in position of balance or in the first position of compression.

Figure 8A schematically shows side views of drawn elements according to a further embodiment of the present invention.

According to the embodiment shown in the figure, the drawn elements 7 comprise an elastic ring 21b, comprising a single circular element. The elastic ring 21 b can be made in any suitable elastic material, for example rubber, plastic, a combination of the same or similar materials. The elastic ring 21 b is made in such a way that by applying a force to the external walls 22b it is possible to cause a compression of the elastic ring 21b. This compression reduces the inner diameter d6 and increases the outer diameter d7 of the elastic ring 21 b with respect to the position of balance. The left panel in the figure shows the elastic ring 21 b in configuration of balance and the right panel shows the elastic ring 21b in position of compression. As already explained, the inner diameter d6 of the elastic ring 21 b in position of balance is larger than the diameter d6' of the elastic ring 21 b in position of compression and the outer diameter d7 of the elastic ring 21b in position of balance is smaller than the diameter d7' of the elastic ring 21b in position of compression.

Figure 8B schematically shows the system according to a further embodiment of the present invention, in a sectional view along a plane passing through the rotation axis of the revolving element. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can be used also in the case where the revolving or translatable element is the panel of a window, of a piece of furniture or of similar elements and the bearing structure is the frame of a window or the bearing structure of a piece of furniture or of similar elements.

The figure shows the first element 1 and the second element 2 of the system. More particularly, as regards the first element 1, it is possible to observe the movable element 3, the housing chamber 4, the connection means 5 comprising the first component 12a of the cam system, the translation areas 16a and 16b, the circulation area 6 and the elastic ring 21 a. As regards the second element 2, it is possible to observe the plate 14, the top-up means 1 Ob, the assembly means 1 1 and the projecting element 20.

In the configuration shown in the figure, the elastic ring 21 b is positioned around the movable element 3, at one of its ends, more particularly at the end of the movable element 3 facing towards the second element 2 of the system. In this position, the elastic ring 21b can determine the size of the circulation area 6 as, in the configuration in which the system is assembled, it is positioned between the movable element 3 and the internal wall of the housing chamber 4. More particularly, in the configuration shown in the figure, the portion of the circulation area 6 that is nearest to the second element 2 of the system is formed by the movable element 3 and the internal wall of the elastic ring 21b. In the figure, the projecting element 20 of the second element 2 is shown partially inserted in the first element 1. In this position, the wall of the end of the projecting element 20 not fixed to the plate 14 rests on the side wall 22b of the elastic ring 21b facing towards the element 2 and thus exerts a force F' on it. The elastic ring 21b is thus in a first position of compression. In this position, the inner diameter d6' of the elastic ring 21b is smaller than the inner diameter d6 of the elastic ring 21b in position of balance. Consequently, the system is in a configuration in which the circulation area 6 is smaller than in the configuration in which the elastic ring 21b is in position of balance. Therefore, in the case where the door leaf A is brought from a configuration in which the door is open to a configuration in which the door is closed and vice versa, the slow-down effect generated by the passage of the viscous fluid V through the circulation area 6 is greater than in the case where the elastic ring 21 b is in position of balance. Figure 8C schematically shows the system shown in Figure 8B, in a further configuration of the system.

The system shown is identical to the system shown in Figure 8B, but in this case the projecting element 20 of the second element 2 is shown, in the figure, further inserted in the first element 1. In this position, the wall of the end of the projecting element 20 not fixed to the plate 14 rests on the side wall 22b of the elastic ring 21 b facing towards the second element 2 of the system, and thus exerts on it a force F" that exceeds F'. The elastic ring 21b is thus in a second position of compression. In this position, the inner diameter d6" of the elastic ring is smaller than the inner diameter d6 of the elastic ring in position of balance, and smaller than the inner diameter d6' of the elastic ring in the first position of compression. Consequently, the system is in a configuration in which the circulation area 6 is even smaller compared to the configurations in which the elastic ring 21b is in position of balance and in which the elastic ring 21 b is in the first position of compression. Therefore, in the case where the door leaf A is brought from a configuration in which the door is open to a configuration in which the door is closed and vice versa, the slow-down effect generated by the passage of the viscous liquid V through the circulation area 6 is greater than in the case where the elastic ring 21 b is in position of balance or in the first position of compression.

Figure 9 schematically shows the closing and/or opening system for revolving or translatable elements according to a further embodiment of the present invention, in a sectional view along a plane passing through the rotation axis of the revolving element. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can be used also in the case where the revolving or translatable element is the panel of a window, of a piece of furniture or of similar elements and the bearing structure is the frame of a window or the bearing structure of a piece of furniture or of similar elements. In the embodiment of the present invention shown in the figure, the system comprises only the first element 1. The first element 1 is, in fact, suited to be mounted simultaneously on a door frame T and on the corresponding door leaf A. The first element 1 comprises a housing chamber 4, a movable element 3 that can move inside the housing chamber 4 along the rotation axis Y of the door leaf A. In fact, the length of the movable element 3, meaning its extension along the axis Y, is smaller than the length of the housing chamber 4. For this reason, the movable element 3 defines, inside the housing chamber 4, two translation areas 16c and 16d defined as areas of the housing chamber 4 not occupied by the movable element 3. The size and the position of the translation areas 16c and 16d depend, clearly, on the position of the movable element 3 inside the housing chamber 4. In the embodiment shown, the housing chamber 4 and the movable element are cylindrical in shape, but they can be in any suitable shape, for example the shape of a cube, a parallelepiped or a similar shape.

The first element 1 comprises, furthermore, connection means 5 suited to connect the door leaf A to the movable element 3. More particularly, the movable element 3 is fixed to one end of the connection means 5 and the door leaf A is fixed to the other end, in such a way that, when the door leaf A rotates around the axis Y in order to bring the door from an open configuration to a closed configuration and vice versa, the connection means 5 rotate integrally with it and consequently also the movable element 3 rotates integrally with the door leaf A inside the housing chamber 4.

The element 1 contains a viscous fluid V, for example oil or similar substances, which fills it up. The viscous fluid V is sealed in the element 1. Furthermore, the system is such that the housing chamber 4 and the movable element 3 are configured in such a way as to define a circulation area 6 suited to allow the circulation of the viscous fluid V from a translation area 16c to the other 16d and vice versa, and such that the movement of the movable element 3 inside the housing chamber 4 is slowed down by the viscous fluid V. More particularly, according to the embodiment shown in the figure, the diameter d'2 of the housing chamber 4, measured along a perpendicular to the rotation axis Y of the door leaf, is larger than the diameter d' l of the movable element 3, in such a way that an area 6 is formed between the two, in which the fluid F can circulate, moving from a translation area 16c to the other 16d and vice versa.

In the embodiment shown in the figure, the movable element 3 comprises a drawn element 7, for example a helical bar 23a. In this case, the housing chamber 4 can comprise a helical profile 23b, in which the helical bar 23a can move. The helical bar 23a is such that the revolving movement of the door leaf A is transformed into a rotation-translation movement of the movable element 3. Therefore, thanks to the helical bar 23a, when the door leaf A is brought from a configuration in which the door is open to a configuration in which it is closed and vice versa, the movable element 3 rotates and at the same time translates inside the housing chamber 4. As a consequence of the rotation-translation movement of the movable element 3, the viscous fluid V is forced to flow from the translation area 16c to the other translation area 16d and vice versa, passing through the circulation area 6 and thus reducing the opening and/or closing speed of the door leaf A.

A return system, for example a spring, suited to bring the door leaf back to the position in which the door is closed, can be installed inside the housing chamber 4. Figure 10A schematically shows the closing and/or opening system for revolving or translatable elements according to a further embodiment of the present invention, in a sectional view along a plane that is perpendicular to the rotation axis of the revolving element. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can be used also in the case where the revolving or translatable element is the panel of a window, of a piece of furniture or of similar elements, and the bearing structure is the frame of a window or the bearing structure of a piece of furniture or of similar elements. In the embodiment of the present invention shown in the figure, the system comprises only the first element 1 , which is cylindrical in shape. The first element 1, in fact, is suited to be simultaneously installed on a door frame T and on the corresponding door leaf A. The first element 1 comprises a housing chamber 4, a movable element 3 suited to rotate inside the housing chamber 4 around the rotation axis Y of the door leaf A (the axis Y is the axis that goes out of the sheet perpendicularly to it). In this embodiment of the invention, the movable element 3 has the shape of a plate that extends parallel to the axis Y, but it can be in any other suitable shape. The movable element 3 comprises two components. The first component 3a is fixed to the internal wall of the housing chamber 4, the second component 3b is connected to the free end of the first component 3a in such a way as to be able to rotate inside the housing chamber around the rotation axis Y of the door leaf A. The movable element 3 defines two translation areas 16e and 16f inside the housing chamber 4. The size and the position of the translation areas 16e and 16f depend, as is clear from the figures, on the position of the second component 3b of the movable element 3 inside the housing chamber 4.

The first element 1 furthermore comprises connection means 5, not shown in the figure, suited to connect the door leaf A to the movable element 3. More particularly, the second component 3b of the movable element 3 is fixed to one end of the connection means 5 and the door leaf A is fixed to the other hand, in such a way that, when the door leaf A rotates around the axis Y to bring the door from an open configuration to a closed configuration and vice versa, the connection means 5 rotate integrally with it and consequently also the second component 3 b of the movable element 3 rotates integrally with the door leaf A inside the housing chamber 4.

The element 1 contains a viscous fluid V, for example oil or similar substances, which fills it up. The viscous fluid V is sealed inside the element 1. Furthermore, the system is such that the housing chamber 4 and the second component 3b of the movable element 3 are configured so as to define a circulation area 6 suited to allow the circulation of the viscous fluid V from a translation area 16e to the other 16f and vice versa, and such that the rotation of the second component 3 b of the movable element 3 inside the housing chamber 4 is slowed down by the viscous fluid V.

A return system, for example a spring, suited to bring the door leaf back to the position in which the door is closed, can be installed inside the housing chamber 4.

The system shown is identical to that shown in Figure 10A. In this case, however, the second component 3b of the movable element 3 is rotated counterclockwise by 90° with respect to the previously shown configuration. Figure 11A schematically shows a sectional view of the closing and/or opening system for revolving or translatable elements according to a further embodiment of the present invention, along a plane perpendicular to the rotation axis of the revolving element. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving clement is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can also be used in the case where the revolving or translatable element is the panel of a window or of a piece of furniture or of similar elements and the bearing structure is a window frame or the bearing structure of a piece of furniture or of similar elements.

In the embodiment of the present invention shown in the figure, the system comprises only the first element 1, which in cross section has the shape of an arc of a circle that subtends an angle larger than 180°. The first element 1 is suited to be mounted simultaneously on a door frame T and on the corresponding door leaf A. The first element 1 comprises a housing chamber 4, a movable element 3 suited to rotate inside the housing chamber 4 around the rotation axis Y of the door leaf A (the axis Y is the axis that goes out of the sheet perpendicularly to it). In this embodiment of the invention, the movable element 3 has the shape of a plate that extends vertically along a portion of the housing chamber 4, but it can be in any other suitable shape. The movable element 3 is connected to the internal wall of the housing chamber 4 in such a way that it can rotate inside the housing chamber around the rotation axis Y of the door leaf A. The movable element 3 defines two translations areas 16g and 16h inside the housing chamber 4. The size and the position of the translation areas 16g and 16h depend, as clearly shown in the figures, on the position of the movable element 3 inside the housing chamber 4.

The first element 1 comprises, furthermore, connection means 5, not shown in the figure, suited to connect the door leaf A to the movable element 3. More particularly, the movable element 3 is fixed to one end of the connection means 5 and the door leaf A is fixed to the other end, in such a way that, when the door leaf A rotates around the axis Y to bring the door from an open configuration to a closed configuration and vice versa, the connection means 5 rotate integrally with it and consequently also the movable element 3 rotates integrally with the door leaf A inside the housing chamber 4.

The element 1 contains a viscous fluid V, for example oil or similar substances, which fills it up. The viscous fluid V is sealed inside the element 1. Furthermore, the system is such that the housing chamber 4 and the movable element 3 are configured in such a way as to define a circulation area 6 suited to allow the circulation of the viscous fluid V from a translation area 16g to the other 16h and vice versa, and such that the rotation of the movable element 3 inside the housing chamber 4 is slowed down by the viscous fluid V.

Figure 1 1B schematically shows the system shown in Figure 1 1 A, in a further configuration of the system.

The system shown is identical to that shown in Figure 1 1A. In this case, however, the movable element 3 is rotated clockwise by 180° with respect to the previously shown configuration.

Figure 12 schematically shows a closing and/or opening system for revolving or translatable elements, according to a further embodiment of the present invention, in a sectional view along a plane perpendicular to the rotation axis of the revolving element. Also in this case, reference is made to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a revolving element, in which the revolving element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can also be used in the case where the revolving or translatable element is the panel of a window or of a piece of furniture or of similar elements, and the bearing structure is a window frame or the bearing structure of a piece of furniture or of similar elements. In the embodiment of the present invention shown in the figure, the system comprises only the first element 1, which is cylindrical in shape. The first element 1 is suited to be simultaneously installed on a door frame T and on the corresponding door leaf A. The first element 1 comprises a housing chamber 4, a movable element 3 suited to move inside the housing chamber 4 along the axis X perpendicular to the rotation axis Y of the door leaf A. In this embodiment, the movable element 3 has the shape of a cylinder, but it can be in any other suitable shape. The movable element 3 defines two translation areas 16i and 161 inside the housing chamber 4. The size and the position of the translation areas 16i and 1 1 depend, as is clear from the figures, on the position of the movable element 3 inside the housing chamber 4.

The first element 1 furthermore comprises connection means 5 suited to connect the door leaf A to the movable element 3. More particularly, the connection means 5 comprise two components. The first component comprises the rod 24a of a connecting rod system, and the second component comprises the head 24b of a connecting rod system. The connecting rod system furthermore comprises two pins 27a and 27b for the relative movement of the two components 24a and 24b of the same. One end of the connection means 5 is fixed to the movable element 3 and the other end is fixed to the door leaf A, in such a way that, when the door leaf A rotates around the axis Y to bring the door from an open configuration to a closed configuration and vice versa, the head 24b of the connecting rod system rotates integrally with it and consequently the movement of the rod 24a of the connecting rod system causes a translation of the movable element 3 inside the housing chamber 4.

The element 1 contains a viscous fluid V, for example oil or similar substances, which fills it up. The viscous fluid V is sealed inside the element 1. Furthermore, the system is such that the housing chamber 4 and the movable element 3 are configured in such a way as to define a circulation area 6 suited to allow the circulation of the viscous fluid V from a translation area 16i to the other 161 and vice versa, and such that the translation of the movable element 3 inside the housing chamber 4 is slowed down by the viscous fluid V.

A return system, for example a spring 26, suited to bring the door leaf back to the closed position of the door, can be installed inside the housing chamber 4.

Figure 13 A schematically shows the closing and/or opening system for revolving or translatable elements according to a further embodiment of the present invention, in a sectional view along a plane that is parallel to the sliding plane of the translatable element.

The top panel of Figure 13, in this case, makes reference to a system for reducing the opening and/or closing speed of revolving or translatable elements, mounted on a translatable element, in which the translatable element is a door leaf and the bearing structure is the door frame T, but it is clear that the system described can also be used in the case where the revolving or translatable element is the panel of a window or of a piece of furniture or of similar elements and the bearing structure is a window frame or the bearing structure of a piece of furniture or of similar elements.

In the embodiment of the present invention shown in the figure, the system comprises only the first element 1, which is cylindrical in shape. The first element 1 is suited to be simultaneously installed on a door frame T and connected to a component Ac of the door leaf A. More particularly, the component Ac of the door leaf A can be stably connected to the first element 1 or can come into contact with it when the door leaf A passes from a position corresponding to a closed configuration of the door to a position corresponding to an open configuration of the door and vice versa. The first element I comprises a housing chamber 4, a movable element 3 suited to move inside the housing chamber 4 along the axis X parallel to the sliding plane of the door leaf A. In this embodiment, the movable element 3 is in the shape of a cylinder, but it can be in any other suitable shape. The movable element 3 defines two translation areas 16m and 16n inside the housing chamber 4. The size and the position of the two translation areas 16m andl 6n depend, as clearly shown in the figures, on the position of the movable element 3 inside the housing chamber 4.

The first element 1 comprises, furthermore, connection means 5 suited to connect the component Ac of the door leaf A to the movable element 3. More particularly, the connection means 5 comprise a rod. One end of the connection means 5 is fixed to the movable element 3 and the other end is fixed to the component Ac of the door leaf A, in such a way that, when the door leaf A translates along the direction X to bring the door from an open configuration to a closed configuration and vice versa, it causes a translation of the movable element 3 inside the housing chamber 4.

The element 1 contains a viscous fluid V, for example oil or similar substances, which fills it up. The viscous fluid V is sealed in the element 1. Furthermore, the system is such that the housing chamber 4 and the movable element 3 are configured in such a way as to define a circulation area 6 suited to allow the circulation of the viscous fluid V from a translation area 16m to the other 16n and vice versa, and such that the translation of the movable element 3 inside the housing chamber 4 is slowed down by the viscous fluid V. In the embodiment illustrated, the system comprises a return system, for example a spring 26, installed in the housing chamber 4 and suited to bring the door leaf back to the position in which the door is closed. The system is shown in the configuration in which it is not in use, with the spring 26 in rest configuration.

More particularly, the system is shown in configuration of use, with the spring 26 in configuration of compression.

Figures 14A and 14B schematically show a door with the system shown in Figure 13 A installed thereon. The door comprises a door leaf and a door frame. The door is shown along the direction perpendicular to the plane defined by the door frame. The door is shown in the open configuration in Figure 14A (closing panel on the left) and in the closed configuration in Figure 14B (closing panel on the right).

In the figures it is possible to observe the door leaf A, comprising the component Ac, the frame T and the element 3 provided with a housing chamber 4 that is substantially as long as the door leaf A.

Even though the present invention has been described with reference to the embodiments illustrated above, it is clear for the expert in the art that several modifications, variants and improvements of the present invention can be carried out in the light of the explanations provided above and within the scope of the attached claims, without departing from the subject of the invention and by the scope of protection provided by the same.

For example, the housing chamber 4 and the movable element 3 can be in shapes different from the cylindrical shape described in the embodiments illustrated above, and for example, where possible, they can be in the shape of a cube or a parallelepiped or a similar shape.

Finally, the fields of application that are considered known to the experts in the art have not been described herein, in order to avoid uselessly putting the illustrated invention in the shade.

Consequently, the invention is not limited to the embodiments described above, but is only limited by the scope of protection defined by the attached claims.
