DETAILED DESCRIPTION OF THE INVENTION

[0066] With particular reference to FIGS. 1-9, a hinge for swing doors according to the invention, denoted globally by reference number 10, comprises a fixed body or part 11 which is to be inserted in a seat formed in a horizontal plane of furniture (base or top, not shown), and a movable body or part 12 which instead is to be inserted into a seat of the door, also not shown in the figures.

[0067] The fixed part 11 is generally made of two enclosures or half-shells, a lower one, indicated by the reference numeral 20 in FIGS. 1-9, and an upper one 20, which in said figures has been removed to show the components provided in the fixed body. The half-shells receive a pair of plates, substantially identical to each other, specifically an upper plate 22a and a lower plate 22b, between which the various components of the hinge are arranged.

[0068] The hinge 10 is of the so-called four-pin type 14, 15, 16 and 17, better shown in the cross-sectional view of FIG. 5B, wherein the movable part 12 intended to be inserted in a door is constrained to the fixed part 11 by means of a pair of rockers or connecting rods 18, 19, so as to accompany the door during the opening and closing movement. Preferably, the two connecting rods 18, 19, which join the two parts 11, 12 of the hinge 10, have a slightly arched shape in the same direction.

[0069] As will be understood, the hinges illustrated in the figures are all of the fully concealed or completely invisible type, in that they have a flat fixed part so as to be fully insertable into the thickness of the base or top of a piece of furniture and the connecting rods extend along a plane perpendicular to the articulation axes.

[0070] The hinge shown in the figures is designed to be mounted in the upper left corner or in the lower right corner of a piece of furniture. Clearly, by specularly varying the arrangement of the components, the same hinge is adapted to be mounted in the other two corners of the piece of furniture.

[0071] With reference to the plan views of FIGS. 3-5A and to FIG. 5B, which is a sectional view along the line B-B of the side view of FIG. 5A, the main components of the hinge 10 will be briefly described, although not essential and not binding for the purposes of the invention.

[0072] The ends of the connecting rod 18, which we shall also call inner connecting rod, are articulated respectively to a pivot point 15 provided in the movable part 12 of the hinge and to a pivot point 14 in the fixed part 11.

[0073] The connecting rod 19, which we shall also call outer connecting rod, is instead articulated to the pivot pin 17 carried by the movable part 12 of the hinge at one of its ends and to the pin 16 of the fixed part 11 to be inserted in the body of the piece of furniture at an intermediate point thereof.

[0074] Conventionally, one of the two connecting rods can be operatively connected to elastic means provided to guide the door during closing movement. In the figures, a hinge 10 is shown in which one end of the outer connecting rod 19 is under the action of a compression spring (not shown) provided in a seat 28 formed in the fixed body 11. This arrangement is purely indicative, being the provision of elastic means operatively connected to one of the connecting rods well known to one skilled in the art.

[0075] In a still conventional manner, in order to prevent the door from slamming against the fixed structure of the piece of furniture during closure, due to the force exerted by the spring, at least one deceleration device 50 can be provided in the hinge 10, which is configured to soften the closing movement of the door.

[0076] In particular, in the embodiment shown in the figures, without any limitation, the deceleration device 50 is represented as a damper comprising a cylinder-piston assembly, constrained to slide linearly in a seat 40 formed between the two plates 22a, 22b, and is actuated by a nose 53 of the inner connecting rod 18, which acts against a suitably shaped extension 58 of the damper cylinder.

[0077] Again, the presence of a decelerating device in hinges of the type described herein is an aspect known to the person skilled in the art, and various other configurations can be provided without limiting the scope of the invention.

[0078] The hinge 10 comprises, in a fully integrated manner, means for adjusting the position of the door with respect to the structure of the cabinet along the three Cardinal axes X, Y, Z, shown in FIG. 1, in which Y represents the vertical direction of the door, while X and Z, orthogonal to the axis Y, indicate the lateral and front directions, respectively.

[0079] The front adjustment means, which allow to modify the position of the door along the axis Z, conventionally comprise a screw-and-nut system provided in the fixed body 12. In particular, a nut body 24 completely housed in the fixed part 12 is constrained to the plates 22a, 22b and a screw 26 is inserted therein, accessible from the outside for adjustment by the user by means of a tool 91 as shown in FIG. 2.

[0080] FIGS. 2A and 2B are schematic representations showing the nut body 24 in two different positions along the axis Z, having made a front adjustment by means of the screw 26.

[0081] The means for adjusting the door with respect to the structure of the piece of furniture along the vertical axis, which are to be considered substantially known in themselves, are best evident with reference to FIGS. 8 and 9. They are entirely housed in the movable part 12 of the hinge with which they interact and conventionally comprise an at least partially threaded pin 31 and a pair of support flanges 36, in this case obtained from a U-shaped folded sheet metal, on which the ends of the connecting rods 18, 19 are pivoted at the pivot points 15, 17 described above. The threaded pin 31 passes through holes 37 formed in the flanges 36 and is constrained to the movable part 12 so that it can only rotate with respect to it. Between the flanges 36 there is a threaded ring 39, possibly made in a single body with the flanges, with which the thread of the pin 31 engages.

[0082] As shown in the figures, the movable part of the hinge 10 has a slotted opening 33 for the access of a tool 92 for vertical adjustment, which allows the threaded pin 31 to be rotated. Screwing the threaded pin 31 into the threaded ring 39, which is arranged in a fixed position between the flanges 36, causes a vertical translation of the moving part 12, obtaining, in a standard way, a vertical adjustment of the door.

[0083] In a completely innovative way with respect to the known hinges, the hinge 10 has means for adjusting the lateral position also provided in the movable part 12 and no longer in the fixed part.

[0084] For this purpose, the movable part 12 of the hinge is advantageously formed by joining a first body 12 and a second body 12, as better shown in FIG. 6 and in FIG. 9.

[0085] The first body 12 has a substantially elongated box-like shape and a first end thereof is intended to receive the flanges 36 to which the connecting rods 18, 19 are pivoted.

[0086] The second body 12 also has a hollow box-like shape such that it accommodates and wraps around the first body 12 and generally has a classic L-shaped configuration for being fixed by means of screws in a seat formed in a door.

[0087] The first body 12 has a protruding flange 13 at the end opposite to that intended to receive the connecting rods 18, 19 in which a hole 25 is provided for the insertion of an eccentric body 25, which will be better illustrated shortly.

[0088] The conformations of the two bodies 12, 12 are such that the coupling takes place with lateral sliding, as is clearer from the representation of FIG. 9.

[0089] The second body 12 in turn has at the end of the hollow space a housing 23 provided with a hole or window 25 such that, after the sliding coupling between the first body 12 and the second body 12 has occurred, the hole 25 on the flange 13 is located behind the window 25, through which the eccentric body 25 is mounted to engage the hole 25.

[0090] With this arrangement, by acting on the eccentric body 25 it is possible to obtain a sliding of the second body 12 with respect to the first body 12.

[0091] For example, by rotating the eccentric body 180 starting from the position shown in FIG. 7A, the configuration of FIG. 7B is obtained, in which the second body 12 has undergone a translation in the direction indicated by the arrow F1 (substantially equivalent to the X direction in FIG. 1). Starting from the position of FIG. 7B, a rotation of the eccentric body 25, in the opposite direction to the previous one, produces a linear sliding of the second body 12 with respect to the first body 12 in the direction of the arrow F2, which is brought back into the configuration of FIG. 7a.

[0092] Recalling that the second body 12 is fixed to the door and the first body 12 is integral with the body of the piece of furniture (by means of the connecting rods 18, 19 that articulate the movable part 12 of the hinge and the fixed part 11, which is installed in the piece of furniture), the movement illustrated above results in a horizontal movement of the door relative to the piece of furniture. This movement, when the piece of furniture is closed, is equivalent to obtaining a lateral adjustment of the door, i.e. the closed door moves along the direction X shown in FIG. 1.

[0093] The hinge according to the present invention, therefore, is able to achieve the intended objects, allowing to carry out an efficient adjustment of the door along the three Cartesian axes, even without lateral adjustment means arranged in the fixed part. The transferal of such means in the movable part of the hinge allows space previously substantially unused in the movable part to be exploited, so that the space previously intended for lateral adjustment in the fixed part can be reduced or destined for other use.

[0094] This space can be used, for example, for the provision of a seat for a second decelerator, according to another aspect of the invention.

[0095] FIG. 10 is an axonometric view of a hinge 110 for a piece of furniture with swing doors comprising a movable part 112 connected to a fixed part 111 by means of a pair of connecting rods 118, 119. In the figure the fixed part is inserted in a seat provided in the base or in the top 130 of a piece of furniture, shown only partially for illustrative purposes.

[0096] The hinge 110 generally features a structure and components similar to the hinge 10, which will therefore not be described in detail. In addition, the hinge 110 provides a decelerator 155 which, when the door is open, projects substantially from the fixed body 111.

[0097] The configuration of the decelerator 155 is best shown in FIGS. 11A and 11B, which are sectional views of the hinge 110 taken along a horizontal plane when the movable part is in the closure phase and when the movable part is closed, respectively.

[0098] As shown in these figures, the decelerator 155 is housed in a vertical seat 145 provided between the pivot point 116 of the connecting rod 119 and a front adjustment screw 126 of the hinge, similar to the screw 26 described above.

[0099] The decelerator 155 is actuated during closing phase directly by the movable part 112, with the contact which preferably occurs at a groove 156 formed at the access point to an eccentric body provided for lateral adjustment as described with reference to the hinge 10.

[0100] Advantageously, the hinge 110 also maintains the arrangement for using a partially protruding damper 150 to be applied to a seat 140, which is entirely similar to the damper 40 described with reference to the hinge 10, as shown in the sections of FIGS. 12A and 12B, showing the hinge with the door in the closing phase and fully closed, respectively.

[0101] With such a configuration, the hinge 110 can alternatively provide a first damper 150 housed in a first seat 140 provided at one end of the fixed body and operable by means of a nose 153 of the connecting rod 118 and a second damper 155 housed in a second seat 145 provided beyond the pivot point 116 of the connecting rod 119 and operable directly from the movable part 112 through the motion of the door.

[0102] This dual arrangement for the decelerator allows to have a single product which can adapt to the most various applications, depending on the required damping performance and customer preferences, simply by installing the decelerator in one seat or in the other.

[0103] Moreover, while a protruding damper 155 might present an aesthetic disadvantage compared to the partially protruding damper 150, on the other side the customer would have the advantage of being able to replace only the damper in case of breakage thereof, or to replace it for a more or less powerful unit depending on the weight of the door.

[0104] In the cross-sectional views of FIGS. 13A and 13B an alternative version of the hinge 110 is shown in which the damper 150 no longer protrudes, but an intermediate roller 158 is applied at its end, partially protruding from the fixed part 111, in order to more gently transmit the motion from the connecting rod 118 to the decelerator, thereby reducing the friction between said elements.

[0105] Advantageously, the hinge 110 can have all or some of the vertical, front and lateral adjustment means as described above with reference to the hinge 10. In particular, advantageously, the hinge 110 has lateral adjustment means provided in the movable part 112, preferably in the form of an eccentric body 125.

[0106] According to a further aspect of the invention, with particular reference to FIGS. 14 to 23, a swing door hinge is now described having the characteristics described so far and allowing an innovative mounting of the fixed part to the furniture structure.

[0107] FIG. 14 shows a hinge 110 before being inserted in a seat 132 formed in the thickness of a top or base of a piece of furniture. The seat 132 has an elongated cross-section for receiving the flat fixed body of the hinge, with two rounded side edges 133, 134, and is typically obtained by milling, as conventional in this field.

[0108] The hinge 110, as already discussed, has a fixed part 111 and a movable part 112 connected together by a pair of connecting rods 118, 119. Hinge 110 may include all the components of hinge 10 described above, to which reference is made for the similarities between the components provided.

[0109] In particular, as described above, the fixed body 111 of the hinge 110 is formed by two half-shells, a lower half-shell 120 and an upper half-shell or cover 120 which enclose and contain, at least partially, the components of the fixed part, and which can comprise, as already described, elastic means, deceleration devices, adjusting means, and so on.

[0110] The two half-shells 120, 120 have a substantially specular shape with respect to each other so that, once assembled, they give the fixed part 111 of the hinge the flat configuration shown in FIGS. 14-23. As clearly seen in these figures, the fixed part 111, unlike known hinges of this type, does not include flanges or extensions with holes for securing the hinge to the furniture seat.

[0111] The fixed part 111 of the hinge according to the present invention has a flattened shape such as that of the standard hinges, with a flattened cross section and a rounded lateral edge 173 so as to mate with the edge 133 of the seat 132. Unlike the standard hinges, however, the assembly of the two half-shells 120, 120 defines on the opposite lateral edge a sort of groove or recess 170, so that once the hinge has been inserted in the seat 132, a free space remains between the groove 170 of the fixed body 111 and the edge 134 of the seat 132.

[0112] FIG. 15 shows the hinge 111 applied in the seat 132 (shown in section for better visualization). From this figure it is appreciated that there is a space 160, with a substantially circular profile, defined between the groove 170 and the edge of the corresponding seat, while substantially no space is created at the other edge 173.

[0113] The space 160 is intended solely to receive a dedicated fixing screw 172 for mounting the hinge to the structure of the piece of furniture. In practice, the proposed solution allows to eliminate the conventional fastening method via holes and flanges protruding from the fixed part of the hinge, since the lateral edge 170 of the fixed part itself is used to ensure the fixing. In fact, the screw 172 is driven into the furniture material, pressing the hinge into the milled seat 132, thus ensuring a stable coupling between the furniture body and the hinge.

[0114] FIG. 16 is a front view showing the hinge with the fixed part 111 inserted in the seat of the piece of furniture 130, fixed by means of the screw 172, while FIG. 17 is a top plan view substantially corresponding to the axonometric view of FIG. 15, with the screw 172 inserted in the seat 160.

[0115] From these figures, as well as from the section view 17B taken along the broken line B-B of FIG. 17 and from FIG. 18, which is an enlargement of the area indicated by A in FIG. 17, the coupling between the hinge 110 and the seat 132 by means of the screw 172 is better visible.

[0116] As mentioned, once the fixed body 111 has been inserted into the seat 132, a space 160 is created between the grooved edge 170 and the edge of the seat 134, suitable for the insertion of the fixing screw. By screwing the screw 172 into this space 170, the screw 172 is caused to engage with the groove 170 and the edge 134 of the seat. The pressure generated between these elements tends to push the fixed part of the hinge to the left, locking it in the seat 132, and is such as to ensure the fastening of the hinge to the piece of furniture.

[0117] A further variant of the fastening mode is shown in FIGS. 19 to 23. In this variant, the mounting of the hinge 110 does not take place directly in the seat 132, but rather a kind of tray or container 180 is interposed between them.

[0118] The tray 180 is generally flattened as shown in FIG. 19, with a front opening 181 of such a section as to receive the fixed part 111 of the hinge 110, as defined above. For this purpose, the tray has an elongated section with two rounded side edges 183, 187 such as to be in turn complementarily inserted and enveloped by the seat 132, which is sized to accommodate it.

[0119] The tray 180 has a bottom or abutment surface 186 opposite the opening 181 on which a pair of holes is provided to allow the tray to be secured to seat 132 by means of a pair of screws 192, as shown in the axonometric section view of FIG. 19a.

[0120] Advantageously, moreover, the tray has on the inner surface of the lateral edge 183 a protrusion or indentation 185 substantially complementary to a dedicated fixing groove 127 provided on the edge 173 of the fixed part of the hinge, as shown in FIG. 20, in which the insertion of the hinge in the seat of the piece of furniture to which a tray 180 has been previously applied is schematically shown.

[0121] The mounting of the hinge 110 in the seat by means of the tray 180 is further schematized in the plan views according to FIGS. 21A to 22C.

[0122] FIG. 21A, which is a schematic top view with the portion of the piece of furniture 130 in section, and FIG. 22a which is a corresponding front view, illustrate a situation in which the fixed part 111 has been inserted into the tray 180, but has not yet been fixed to the seat.

[0123] In this situation, since the longitudinal dimension of the opening 181 of the tray 180 is slightly greater than the length of the fixed part 111, the coupling between the fixed part and the tray is such as to allow a lateral sliding of the fixed part. FIG. 22A shows a space between the edge 183 of the tray and the side edge 173 of the fixed part.

[0124] After insertion, the fixed part is laterally translated into the position shown in FIGS. 21B and 22B. In this situation, the space between the lateral edges 173 and 183 is reduced, while a space 160 has been created between the groove 170 and the opposite lateral edge 187 of the tray, intended to accommodate a screw 172.

[0125] In this condition, moreover, the groove 127 of the lateral edge 173 of the fixed body engages and couples with the indentation 185 provided on the edge of the tray, to which it is complementary.

[0126] The fixed part of the hinge is secured to the tray by screwing the screw 172 into the space 160 between the groove 170 and the edge 187. FIGS. 21C and 22C show this condition. As in the previous case, screwing the screw results in coupling in part on the hinge and in part on the tray, which are put under mutual pressure in order to eliminate any movement. Secure fastening is further ensured, on the opposite edge, by the engagement between the indentation 185 and the groove 127, which prevents movement in the front direction.

[0127] A hinge fully coupled to the housing of the piece of furniture by means of a tray and a fixing screw is illustrated in the axonometric view of FIG. 23.

[0128] From the above description, the advantages of a hinge for furniture with swing doors according to the invention, and its alternative embodiments, are evident.

[0129] In particular, a hinge with the lateral adjustment means in the movable part allows, on the one hand, to reduce the size of the fixed body, positively impacting the production thereof and the installation process, which is an extremely important aspect in this field, and on the other hand, to free up space for the provision of other components, such as the provision of an additional damper.

[0130] Not least, a hinge according to a further aspect of the invention has undoubted installation advantages, providing a fixed part that can be directly fixed to the milled seat in the thickness of the piece of furniture, thus eliminating the flange protruding from said fixed part and avoiding additional and unesthetic fixing holes.

[0131] Naturally, the present invention is not limited to the particular embodiments described above and illustrated in the accompanying drawings, but numerous modifications and variations may be made by a person skilled in the art without thereby departing from the scope of the invention as defined in the appended claims.
