DETAILED DESCRIPTION OF THE INVENTION

[0021] Referring to the foregoing figures, in this specification, a hinge 1 for the rotational movement of a closing element A, such as a leaf, preferably made of glass, a door, etc., with respect to a fixed support structure S such as a wall, floor, frame, etc. will be described.

[0022] Preferably, the closing element A may be a glass door defining a plane π, but the fixed support structure S may also be the floor, ceiling, or the upper part of the door sub-frame.

[0023] In the following, reference is made to door A and floor S, it being understood that the closing element and the fixed support structure may vary without departing from the scope of protection of the appended claims.

[0024] The present invention can include various parts and / or similar or identical elements. Unless otherwise specified, similar or identical parts and / or elements are denoted using a single reference number, it being clear that the technical features described are common to all similar or identical parts and / or elements.

[0025] In the present specification, FIGS. 1 to 6B show a first embodiment of the hinge 1 and its relative fixing system 4 for the door A, and FIGS. 7 to 11 show further embodiments thereof. Unless otherwise specified, the features referred to in the following description are intended to be common to both embodiments.

[0026] The door A can rotate between at least one closed position and at least one open position.

[0027] As particularly shown in FIGS. 3A to 3B, the hinge 1 can be a mechanical hinge, i.e., a hinge without hydraulic damping means.

[0028] According to a preferred but non-exclusive embodiment, the hinge 1 can be a hinge for a swing door A.

[0029] Such a hinge 1 can comprise a fixed element 2 that can be fixed to the floor or ceiling, and a movable element 3 that can be fixed to the door A.

[0030] Preferably, the movable element 3 can include a hinge body 30 that defines an axis Y'.

[0031] As particularly shown in FIG. 2, the fixed element 2 can comprise a plate 10 that can be fixed to the floor, and a pin 20 that is coupled to each other.

[0032] Suitably, the hinge body 30 and the pin 20 can be coupled to rotate relative to each other about the longitudinal axis X to define the open and closed positions of the door A.

[0033] It is clear that, without departing from the scope of protection of the appended claims, the fixed element 2 can include the hinge body 30 while the movable element 3 can include the pin 20.

[0034] Preferably, the pin 20 can define the axis of rotation X and can comprise a body 27 having a cam element 22.

[0035] The body 27 can further comprise a coupling zone 23 suitable for coupling the pin 20 to the plate 10.

[0036] Preferably, the pin 20 can be positioned in the coupling zone 23 and can include a pair of opposing longitudinal protrusions 21', 21'' that preferably extend perpendicular to the axis X along the axis Y''.

[0037] According to a preferred but non-exclusive embodiment, the aforementioned opposing longitudinal protrusions 21', 21'' can correspond to the ends of a substantially cylindrical pin 21 that is integrally joined to and projects from the pin 20.

[0038] Preferably, the aforementioned pin 21 can be inserted into the through-hole 211 of the coupling zone 23 of the pin 20. This embodiment is particularly simple to implement.

[0039] Although reference is made hereinafter to a through-pin, it is clear that, without departing from the scope of protection of the appended claims, the opposing longitudinal protrusions 21', 21'' can be made as a single part with the pin.

[0040] Furthermore, the coupling zone 23 of the pin 20 can include a curved coupling end 24.

[0041] In particular, the curved coupling end 24 may be a substantially spherical cap having a diameter φ24.

[0042] Suitably, the plate 10 can have a substantially longitudinal extension along the axis Y and can include a surface 11' for contacting a fixed support structure S that defines a plane π'' substantially coinciding with the floor or ceiling surface.

[0043] To fix the plate 10 to the ceiling surface, a suitable fixing sleeve 100 passing through the elongated slot 101 can be provided.

[0044] The plate 10 may comprise two opposing faces 11 and 12, of which the face 11 may be fixed to the floor or ceiling.

[0045] It may also comprise a pair of opposing side faces 15.

[0046] In particular, as shown in FIGS. 1-2, the face 12 can comprise a seat 16 suitable for receiving the coupling zone of the pin 20.

[0047] For this purpose, the seat 16 can have a central portion 16'' suitable for receiving the curved coupling end 24 and a pair of longitudinal portions 16' suitable for receiving the opposing longitudinal protrusions 21', 21''.

[0048] It is clear that the seat 16 may have only the central portion 16'' without the longitudinal portions 16' without departing from the scope of protection of the appended claims.

[0049] It is also clear that the seat 16 may have only one of the central portion 16'' and the longitudinal portions 16' without departing from the scope of protection of the appended claims.

[0050] It is clear that the central portion 16'' of the seat portion 16 may have such a geometric shape as to receive the curved coupling end 24. Such a geometric shape may vary and may be, for example, cylindrical, parallelepiped, etc., provided that it is suitable for performing the function of receiving the curved coupling end 24.

[0051] The upper opening 16''' of the central portion 16'' of the seat portion 16 can have dimensions and / or a configuration that allows the passage of the curved coupling end 24. For example, it may be rectangular, square, circular, or elliptical.

[0052] On the other hand, the bottom wall 16'''' of the central portion 16'' of the seat portion 16 can have dimensions and / or a configuration such that the curved coupling end 24 can rotate. For example, it may be flat, convergent, or curved. In some cases, the central portion 16'' of the seat portion 16 may not have a bottom wall 16''''.

[0053] Preferably, the portion 16'' can have a shape that is substantially complementary to the shape of the curved coupling end 24. Thus, it can be substantially in the shape of a spherical cap and can have a diameter φ16'' that is substantially equal to or slightly larger than the diameter φ24.

[0054] It is clear that the foregoing embodiments are provided only as non-limiting examples of the present invention.

[0055] For example, as shown in FIG. 1C, the bottom wall 16'''' of the central portion 16'' of the seat portion 16 can have a curved shape, particularly a spherical cap, while the coupling end 24 can be flat or any other shape as long as it is suitable for rotating on the bottom wall 16''''.

[0056] Optionally, both the bottom wall 16'''' of the central portion 16'' of the seat portion 16 and the coupling end 24 can be curved, for example, in the shape of a spherical cap.

[0057] Furthermore, for example, as shown in FIG. 1D, one or more curved or spherical interface elements can be provided between the bottom wall 16'''' of the central portion 16'' of the seat portion 16 and the coupling end 24, even if neither of them is curved or spherical.

[0058] Generally, at least one of the bottom wall 16'''' of the central portion 16'' of the seat portion 16 or the coupling end portion 24 may be curved or spherical without departing from the scope of protection of the appended claims.

[0059] It is also clear that the seat portion 16 may have an inner surface that includes or consists of the bottom wall 16''''. For example, in the case of a seat portion 16 in the shape of a spherical cap, the inner surface may be constituted by the bottom wall 16''''.

[0060] Preferably, as shown in FIG. 1B, the distance L16' between the opposing bottom surfaces 163, 164 of the portion 16' may be substantially equal to or slightly greater than the length L21 of the pin 21.

[0061] Preferably, each portion 16' can have a width W16' that is slightly larger than the diameter φ21 of the pin 21, whereby the pin 21 is movable inside each portion 16'.

[0062] In particular, each portion 16' can include a pair of opposing side surfaces 165, 166 parallel to a plane π having a distance defined by the width W16'.

[0063] Each portion 16' can also include a bottom surface 17. In some cases, the aforementioned bottom surface 17 may be substantially flat as in the embodiments shown in FIGS. 7 - 11, or may be inclined defining an axis that substantially converges with respect to the axis X as in the embodiments shown in FIGS. 1 - 6B.

[0064] The dimensions shown above may be such as to allow proper movement of the pin 20 inside the seat portion 16, for example as shown in FIGS. 10B to 10E.

[0065] When performing such movement, there is a possibility that the ends 21′, 21″ and the surfaces 163, 164 and / or the ends 21′, 21″ and the surfaces 165, 166 come into contact with each other.

[0066] Thanks to the above, the assembly between the pin 21 and the pin 20 and the curved connecting end 24 of the elongated slot 16 can function as an adjusting means 28 for adjusting the spatial position of the hinge body 30 relative to the fixed plate 10.

[0067] Furthermore, the slot 101 can function as a means for adjusting the relative position of the fixed plate 10 - hinge body 30 assembly relative to the fixed support structure S.

[0068] Thereby, the position of the door A relative to the fixed support structure can be accurately adjusted.

[0069] Such adjustment is carried out along various directions, particularly as shown in FIGS. 10A to 10E.

[0070] Particularly as shown in FIG. 10A, by using a special wrench W to loosen and then tighten the pin 100′ of the sleeve 100, it is possible to facilitate the translation of the fixed plate 10 along the axis Y so as to actually move the fixed plate 10 relative to the floor or ceiling. The length of this translation is defined by the length of the elongated slot 101.

[0071] Particularly as shown in FIGS. 10B and 10D, by utilizing the specific shapes of the curved connecting end 24 of the pin 20 and the central portion 16″ of the seat portion 16, it is also possible to facilitate the rotation of the pin 20 respectively about the axis Z perpendicular to the axis Y and about the axis Y″ defined by the pin 21.

[0072] In particular, as shown in FIG. 10C, the dimensional relationship between pin 21 and portion 16' of seat 16 also allows for promoting the rotation of pin 20 about the axis X of pin 20.

[0073] This particular geometric shape of the curved coupling end 24 of pin 20 and the central portion 16'' of seat 16 also enables the generation of the aforementioned movement, and as a result, the assembly of pin 20 - hinge body 30 can be adjusted at various positions.

[0074] The adjusting means 28 can suitably comprise two pairs of adjusting grub screws 14, 14'.

[0075] The adjusting grub screws 14, 14' may be arranged at both ends 161, 162 of seat 16. More specifically, the adjusting grub screws 14, 14' may be inserted through surfaces 165, 166 so as to interact with pin 21 arranged on seat 16.

[0076] Thereby, the rotation of pin 20 about the axis X of pin 20 can be promoted.

[0077] The pair of adjusting grub screws 14, 14' can be suitably inserted into their respective female screw holes 13, 13'. The female screw holes may be formed two - by - two on the opposing surfaces 15 of plate 10.

[0078] Thereby, it becomes possible to guide the movement of pin 21 within seat 16 with high precision.

[0079] As particularly shown in FIG. 10E, the grub screws 14, 14' and the screw holes 13, 13' can also function as stopping means for locking the movement of pin 21 when the spatial position of hinge body 30 is adjusted with respect to plate 10.

[0080] The adjustment means 28 can preferably comprise a single pair of adjustment grub screws that can be coupled to a single pair of threaded holes made at a position facing the axis Y of the side surface 15 of the plate 10, without departing from the scope of protection of the appended claims.

[0081] In particular, as shown in FIGS. 12 to 15C, the upper hinge 1 can also include a hinge body 30 and a pin 20 that are interconnected so as to rotate about a rotation axis. A fixing plate 10 that can be fixed to the upper part of the door frame or the ceiling by a dowel 100 may be connected to the pin.

[0082] Such a fixing plate 10 can suitably include a rear hole 200 and three adjacent front holes 201.

[0083] This configuration of the fixing plate 10 makes it possible to change the type of door A without having to drill the wall and without changing the hinge, rather, as shown in FIGS. 15A to 15C, by removing the pin 100´ of the front sleeve 100 from one of the adjacent holes 201 and reinserting it into another one of the holes 201.

[0084] In particular, FIG. 15A shows the positioning of the fixing plate 10 in the case of a swing door opening to the right, FIG. 15B shows the positioning of the fixing plate 10 in the case of a swing door opening to the left, and FIG. 15C shows the positioning of the fixing plate 10 in the case of a free door without a leaf.

[0085] Advantageously, the positioning of the fixing plate 10 according to FIGS. 15A and 15B makes it possible to apply a preload to the hinge 1 without acting on its mechanical parts.

[0086] According to a further aspect of the invention, the hinge body 30 may be substantially box-shaped and may comprise an upper surface 31 having a predetermined width L31.

[0087] Furthermore, as particularly shown in FIG. 4, the hinge body 30 can include a pair of side surfaces 33 facing the sliding surface 31 and adjacent to the sliding surface 31.

[0088] In a preferred but non-exclusive embodiment, the hinge body 30 can consist of two half-shells 30', 30'' that can be coupled to each other by sliding along the axis Y' with the pin 20 interposed therebetween.

[0089] For example, the hinge body 30 can be manufactured according to the disclosure of International Application Publication No. WO 2017 / 195180 in the name of the applicant, and reference is made thereto for examination purposes.

[0090] The hinge body 30 can suitably be provided with a seat 50 for inserting the pin 20 therein.

[0091] Additionally, the hinge body 30 can be provided with an operating chamber 55 that defines the axis Y'.

[0092] The operating chamber 55 can be provided with a slider element 51 that is slidable between two end-stroke positions that define the opening and closing of the door A.

[0093] The slider element 51 can include a housing zone 51' into which a cam follower element 52 and an opposing housing zone 51'' can be inserted.

[0094] The cam follower element 52 can be substantially spherical or cylindrical and can contact the cam element 22.

[0095] It is obvious that the operating chamber 55 can also be provided with elastic reaction means such as a spring 56, for example, to facilitate the automatic opening and closing of the door A and to facilitate the passage of the plunger 51 from one end-stroke position to the other.

[0096] The aforementioned spring 56 may comprise two opposite ends 56', 56'', one of which may be inserted into the housing zone 51''.

[0097] Preferably, the seat 50 can comprise damping means 54 that interact with the contact surface 25 of the cam element 22.

[0098] The damping means 54 can cooperate with the eccentricity inherent in the cam element 22 to appropriately damp the rotation of the fixed element 2 and the movable element 3 about the axis X in a differentiated manner.

[0099] The damping means 54 can preferably have a contact surface 54' that contacts the contact surface 25 of the cam element 22.

[0100] It is clear that the damping means may, without departing from the scope of protection of the appended claims, be an integral part of the pin 20, or be coupled to the pin, and interact with the inner wall of the chamber 50, for example as shown in Figure 3C.

[0101] In particular, the damping means 54 may comprise or consist of, for example, a polymer element having a flat or parallelepiped shape.

[0102] In particular, a polymer having high elasticity and high resistance to wear, tearing and permanent deformation caused by the frictional force generated by the interaction between the polymer element 54 itself and the surface 25 of the cam 22 can be used.

[0103] Advantageously, the material of the polymer element 54 may be an elastomer.

[0104] More specifically, the polymer element 54 may be a polyurethane elastomer having a hardness of 60 Sh A to 100 Sh A (between 60 and 100 Shore A hardness), preferably 80 Sh A to 95 Sh A (between 80 and 95 Shore A hardness).

[0105] For example, the elastomer may be Brooklan (registered trademark).

[0106] Preferably, the seat part 50 may include a wall 53 facing an operating chamber 55 to which the polymer element 54 is coupled.

[0107] This makes it possible to optimize the differentiated damping action resulting from the interaction between the polymer element 54 and the surface 25.

[0108] The hinge 1 can be fixed to the fixed support structure S, for example, on the floor, ceiling or upper part of the frame, by means of a suitable fixing system 4, as will be described in more detail below.

[0109] For example, as shown in FIG. 7, the fixing system 4 can include the hinge 1 and a pair of clamp elements 40 designed to lock the door A on both sides. For this purpose, a suitable substantially rectangular pocket T may be provided in the door A in a manner known per se.

[0110] Each of the clamp elements 40 may include a first inner surface 46 suitable for remaining facing the door A, a second inner surface 46' suitable for remaining facing the hinge body 30, and an outer surface 49 and a lower surface 41 facing the hinge body 30.

[0111] In the case of a glass door, an interface element A1 made of a polymer or elastomer material may be arranged in a manner known per se between each clamp element 40 and the glass surface.

[0112] The clamp elements 40 may be suitably coupled to each other by coupling means 48 so that the door A remains integrally joined therebetween.

[0113] Advantageously, the distance d between the side surfaces 46 may vary according to the thickness s of the door A.

[0114] This allows doors A of different thicknesses s, having a size substantially smaller than the width L31 of the sliding surface 31, to be supported in the same way as larger sizes.

[0115] The door A may also be properly placed on the sliding surface 31 of the hinge body 30.

[0116] In this way, the weight of the door A can contribute to fixing the door A to the floor.

[0117] The coupling means 48 may be defined by screw and nut-screw means 45, 44´´.

[0118] In particular, the screw 45 may be provided through a completely smooth through-hole 44´ of the first clamp element 40 and engage with a corresponding nut-screw provided inside the hole 44´´ of the other clamp element 40.

[0119] Advantageously, for each screw 45 to engage with the corresponding screw hole 44´´, it must pass through the hinge body 30.

[0120] For this purpose, one of the screws 45 can pass above the surface 31 and through a hole A1´ made in the interface element A1. For this purpose, the pocket T can provide a suitable passage for the screw 45.

[0121] The other screw 45 can also pass through a suitable smooth hole 45´ passing through the hinge body 30.

[0122] However, it is clear that the coupling means 48 can comprise a single screw that can be screwed into a single nut-screw without departing from the scope of protection of the appended claims.

[0123] In order to guide the movement of the clamp element 40, appropriate guiding and centering means can be provided when the screw 45 is screwed in and when the clamp element 40 is centered with respect to the hinge body 30.

[0124] In a preferred but non-exclusive embodiment, the aforementioned guiding and centering means can comprise one or more male elements, such as elongate elements 32', 32'', protruding from the side face 33 of the hinge body 30 so as to engage corresponding female seats, such as the guiding and centering holes 320 provided in the clamp element 40.

[0125] According to a preferred but non-exclusive embodiment, the elongate elements 32', 32'' can be provided symmetrically with respect to a plane of symmetry π' passing through the axis Y'.

[0126] However, it is clear that only one of the side faces 33 of the hinge body 30 can contain one or more male elements without departing from the scope of protection of the appended claims.

[0127] Furthermore, it is clear that one or more male elements can be provided on the second surface 46' of the hinge body and / or on one or both of the female seats without departing from the scope of protection of the appended claims.

[0128] Furthermore, it is clear that the hinge body and the clamp element may include male and female elements.

[0129] Preferably, as particularly seen in FIGS. 6A and 6B, the elongate elements 32', 32'' may be provided by a pin 32 passing through the hinge body 30. This makes it possible to provide the elongate elements 32', 32'' in a simple and cost-effective manner.

[0130] When the clamp elements 40 are interconnected and the door A is locked therebetween, the hinge body 30 must be locked to the clamp element 40 by suitable locking means 47.

[0131] For this purpose, in a preferred but non-exclusive embodiment shown for example in FIG. 7, the locking means 47 can include or consist of an annular spacer 300 that can be inserted into the elongated elements 32', 32'' so as to remain interposed between the hinge body 30 and the clamping element 40.

[0132] One or more spacers having a length that can be at least equal to the distance between the second inner surface 46' and the opposing side surface 33 of the hinge body 30 can be inserted into the elongated elements 32', 32''.

[0133] According to a further embodiment shown for example in FIG. 4, the locking means 47 can comprise one or more pairs of adjusting grub screws 43, 43', 43'' that can be inserted into the threaded holes 42, 42', 42'' provided in the surfaces 46 and 49.

[0134] Such an embodiment of the locking means 47 can properly and evenly space the clamping element 40 with respect to the hinge body 30. On the other hand, by properly acting on the grub screws, the door A can be moved with respect to the hinge body 30.

[0135] The fixing system 4 enables the door A of any thickness to be easily and quickly coupled to the hinge 1. The fixing system 4 actually enables a door A that is even thicker than the width L31 of the surface 31 to be fixed.

[0136] A further advantage of the fixing system 4, particularly shown in FIG. 11, lies in the fact that the element 350 for covering the clamping element 40 is always adhered to the door A regardless of its thickness.

[0137] In light of the above, it is clear that the present invention achieves the preset objectives.

[0138] The present invention can accept numerous modifications and variations that are all included in the concept of the present invention outlined in the appended claims. All details can be replaced with other technically equivalent elements, and the materials can vary according to technical requirements without departing from the scope of protection of the present invention.

[0139] Although the present invention has been particularly described with reference to the accompanying drawings, the reference numbers used in the specification and claims are for the purpose of improving the understanding of the present invention and, therefore, do not limit the scope of protection claimed in any way.
