    TECHNICAL FIELD
    [01] The present invention relates to a decelerated hinge for furniture doors and, specifically, to a hinge suitable for pieces of furniture provided with a face frame for fixing the hinges themselves. BACKGROUND OF THE INVENTION
    [02] In the furniture industry, with the purpose of supporting furniture doors in an oscillating way, hinges are conventionally used, comprising a fixed part connected to the body of the piece of furniture and a moving part consisting of a box, connectable to the door.
    [03] In the case of furniture pieces that have a face structure for fixing the hinges, normally used in the American market, the hinges themselves usually require that the box be connected to an arm of the fixed part through a single hinge pin. .
    [04] For the purpose of keeping the door in a closed position, the hinges also comprise suitable spring means, which can, for example, take the form of two torsion springs positioned in the vicinity of the side walls of the box, or form of a leaf spring fixed inside the box in a central position, and tensioned in such a way as to pull the arm of the fixed part in the direction of the hinge closure.
    [05] In order to slow down the hinge closing movement, in the presence of the lateral torsion closing springs, a linear deceleration device can be placed inside the box, depending on the available space left by the closing springs themselves, said device comprising a centrally arranged fluid type deceleration cylinder and two return springs positioned on opposite sides of the deceleration cylinder itself.
    [06] On the other hand, with the presence of a leaf closing spring or any other constructive element installed in the central position of the box, it is impossible, due to the lack of space, to accommodate the known deceleration device inside the the box itself or, in any case, it would be necessary to further reduce the dimensions of a deceleration device of this type, already of critical size due to the limited space available.
    [07] The main objective of the present invention, therefore, is to reveal a decelerated hinge for furniture doors, specifically for pieces of furniture equipped with a face frame for fixing, which feature a deceleration device configured to be suitable to be associated with closing means placed centrally in the hinge box.
    [08] Another objective of the present invention is to reveal a hinge of the type considered, which is capable of exerting an effective deceleration action along a particularly long arc of oscillation.
    [09] Yet another objective of the present invention is to reveal a hinge of the type considered, in which the deceleration device is of simple construction and which has components that can be easily assembled together.
    [010] The precedent described above is achievable by means of a hinge for mounting a door on a piece of furniture, comprising:
    [011] - a hinge arm that can be fixed to a fixed part of the piece of furniture;
    [012] - a box fixed to a door of the piece of furniture, the box being oscillatingly connected to the mentioned hinge arm at a rear longitudinal end of the box, and having side walls extending longitudinally on opposite sides of the box, starting the from the aforementioned rear end;
    [013] - a spring means for closing the hinge; and
    [014] - a linear type deceleration device arranged inside the box, the device comprising a fluid type deceleration cylinder and a return spring means, operationally connected to each other, and characterized by the fact that said cylinder fluid-type deceleration means and said return spring means extend parallel and spaced from each other, said fluid-type deceleration cylinder being positioned in proximity to a first of the said side walls of the box and said means of spring being positioned in the vicinity of the opposite side wall of the box.
    [015] The additional features of the present invention are further defined in the subsequent claims.
    [016] The characteristics and advantages of the present invention will become more evident from the description that follows, of a preferred modality, but not limiting the execution of the hinge with a deceleration device for pieces of furniture, with reference to the attached figures.

    [026] The hinge according to the present invention, indicated in general in the attached figures with the numerical reference 10, is particularly suitable to be configured for application in an American type piece of furniture, equipped with a face frame 11 to which the hinges are attached.
    [027] This type of hinge 10 generally comprises an arm 12 for fixing the hinge itself to a fixed part of the furniture piece, particularly to the face frame 11, and a box 13 to be fixed to the door 14 of the furniture piece.
    [028] As best illustrated in Figures 3 and 7, the housing 13 is oscillatingly connected to the fixing arm 12 at a rear longitudinal end of the housing itself 13, preferably with the use of a single oscillating pin 15 that extends transversely across with respect to the longitudinal axis of the fixing arm 12, in such a way that the box 13 can rotate between an open position of the door, shown in Figure 7, and a closed position of the door, shown in Figure 9, under the action of the closing means spring of a known type, for example at least one leaf spring 16, arranged centrally and longitudinally within the housing 13.
    [029] As illustrated in Figure 3, the hinge box 13 comprises a bottom wall 17 and side walls 18 ', 18' 'that extend longitudinally on opposite sides of the box, starting at the rear end.
    [030] In a front area, the bottom wall 17 has a bridge 17 ', which can be obtained by cutting and plastic deformation of the metal plate, and which defines an insertion seat for a front end of the leaf spring 16 ; the rear end of the spring 16 is, however, curved in the direction of the pivot pin 15 and rests on a cam 19 inserted in the lower edge of an opening 20 formed in the front part 21 of the hinge arm 12.
    [031] The hinge 10 also comprises a linear type deceleration device 22, positioned inside the box 13, which comprises a fluid type deceleration cylinder 23 and a spring return means 24, operationally connected to each other.
    [032] According to the present invention, the fluid type deceleration cylinder 23 and the spring return means 24 extend parallel and spaced from each other, the fluid type deceleration cylinder being positioned in proximity of a first side wall 18 'of the box 13, and the spring return means 24 are positioned in the vicinity of the opposite side wall 18' of the box 13, the cylinder 23 and the return means 24 are consequently arranged separately from each other. other.
    [033] Specifically, with respect to the illustrated execution mode, in which the spring closing means has the shape of a leaf spring 16, the fluid type deceleration cylinder 23 and the spring return means 24 extend parallel and spaced from each other along respective opposite sides of the leaf spring 16.
    [034] In general, the deceleration device 22 comprises a retaining body or housing 25 that can be fixed inside the hinge box 13 at a front end thereof, and a slide 26 arranged in a sliding way at least partially inside the body. retaining plate 25 parallel to the bottom wall 17 of the box 13, or otherwise slidably arranged between the retaining body 25 and the bottom wall 17 of the box 13.
    [035] Slider 26 can be moved between a first extended portion, corresponding to the open position of the hinge shown in Figure 7, and a second contracted position corresponding to the closed portion of the hinge shown in Figure 9.
    [036] As best illustrated in Figure 5, the deceleration cylinder 23 comprises a piston 27 movable within a chamber 28 for the fluid, preferably consisting of oil or other viscous fluid.
    [037] Preferably, the slider 26 comprises a first 26 'and a second 26' 'hollow cylindrical parts which are operationally connected to each other, for example, with the aid of a transverse connection element 29, and extend parallel and spaced each other; the first hollow cylindrical part 26 'defines the chamber 28 for the piston 27 of the deceleration cylinder (23), while the second hollow cylindrical part 26' 'defines an accommodation seat for the spring return means 24.
    [038] For the purpose of actuation of the deceleration device, the first and second cylindrical parts 26 ', 26' 'of the slider 26, at one end extending from the retaining body 25 towards the rear end of the box 13, present respective closing walls 30 ', 30' 'provided with molded contact surfaces or cams 31', 31 '' to contact the corresponding drive surfaces 32 ', 32' 'provided on the hinge arm; particularly, with reference to the preferred embodiment illustrated, the drive surfaces 32 ', 32' 'extend in the folded sections of the front part 21 of the arm 12, on the sides of the opening 20 for the leaf spring 16.
    [039] Preferably, the molded contact surfaces 31 ', 31' 'are shaped like an arc, with the concavity facing the actuation surfaces 32', 32 '' of the hinge arm 12; with the appropriate configuration of the contact surfaces 31 ', 31' 'and particularly with the modification of their curvature, it is possible to modulate the brake action according to the need and the type of application of the hinge, for example, providing a curvature of the surfaces in such a way as to impose a practically constant movement of the slider along the hinge oscillation arc 15 during which braking occurs, or otherwise, providing an increase in the movement of the slider along the hinge oscillation arc at the closing direction.
    [040] For the purpose of guiding the slide of the slide 26, the closing walls 30 ', 30' 'of the cylindrical parts 26', 26 '' of the slide have lateral projections of guide 33 shaped and arranged so as to slide along respective side walls 18 ', 18' 'of box 13.
    [041] In turn, the cylindrical parts 26 ', 26' 'of the slide 26 have lateral guide surfaces 34 shaped and arranged so as to slide along the internal surfaces 35 of the retaining body 25.
    [042] In this way, regardless of the asymmetry of the arrangement of the spring return means 24 in the deceleration device 22, a good sliding of the slider 26 is obtained, thereby avoiding its interference or blocking.
    [043] As illustrated in Figures 5 and 6, with reference to the preferred embodiment in which the slider comprises the aforementioned hollow cylindrical parts 26 ', 26' ', the deceleration cylinder 23 comprises the first hollow cylindrical part 26' itself defines chamber 28 for the piston.
    [044] The piston 27 comprises, on its front side, a blind axial hole for the insertion of a rod 36 under pressure, and peripherally has an annular groove 37 to accommodate a gasket ring 38; the annular groove 37 is located between the front wall 27 'and the rear wall 27' 'of the piston, which have respective peripheral passages 39', 39 '' for the fluid, the rear passages 39 '' having an opening larger to facilitate the return of the device.
    [045] For the same purpose, the aforementioned gasket ring 38 is located in the groove 37 with axial and radial clearance, the outer surface of the gasket ring 38 being adhered to the internal surface of the chamber 28 of the deceleration cylinder.
    [046] The cylinder 23 also comprises a volume compensating ring element 40, preferably in the form of a closed cell rubber ring, as well as a sealing ring 41, for example, of the type with a flap, to ensure the seal between the piston rod 36 and the inner surface of the piston chamber 28.
    [047] Finally, the cylinder 23 comprises a closing cover ring 42 for closing the chamber, which can be fixed on the front end of the first cylindrical part 26 ', for example, using a recess in the form of a ring that can be snapped under pressure in a peripheral edge of the cover 42.
    [048] In this configuration, the piston rod 36 successively extends through the cover 42, the sealing ring 41 and the volume compensating element 40, so as to be inserted under pressure in an axial orifice of the piston 27; with the purpose of obtaining a better retention, the rod 36 has peripheral teeth or a knurling on the end to be fitted under pressure in the axial orifice of the piston 27.
    [049] The piston rod 36 protrudes from a front end of the first cylindrical part 26 'of the slide 26, ending with a head 36' engaging the retaining body 25 of the device.
    [050] Preferably, the retaining body 25 has a top wall and two side walls 43 that extend according to a U-shaped cross section, and comprises a front wall 44 equipped with an engaging seat 44 'for the piston rod head 36 '.
    [051] As illustrated in Figure 5, in order to obtain smooth and linear operation of the deceleration cylinder 23, the chamber 28 preferably has at least one passage groove 45 for the fluid extending longitudinally along at least a part of the inner surface of the first cylindrical part 26 '.
    [052] For the purpose of modulating the braking action of cylinder 23, the opening of the passage groove 45 for the fluid presents a variable cross section along its longitudinal extension.
    [053] As illustrated in Figure 4, the return means 24, which has the function of returning the slide 26 from its contracted position to its extended position, preferably comprises a helical spring extending between a reference projection 46 provided on the wall front 44 of the retaining body 25 and the bottom of the second cylindrical part 26 '' of the slider.
    [054] With the intention of enabling a simple and quick fixation of the deceleration device 22, the retaining body 25 preferably has side latches 47 with a spring effect that are pressable into corresponding side openings 48 in the hinge box 13, or vice versa.
    [055] The side walls 18 ', 18' 'of the box 13 preferably have a first lateral locking projection 49 for the retaining body 25 in a central area, and a second stroke limiting projection 50 for the slide 26 in an area rear, both protruding from the inside of box 13.
    [056] As illustrated in Figure 8, during the closing movement of the hinge according to the present invention, the drive surfaces 32 ', 32' 'of the hinge arm 12 come into contact with the molded surfaces 31', 31 ' 'of the slide 26 at an angle of the hinge comprised, for example, between 30 ° and 40 °, from the completely closed position of the same illustrated in Figure 9; for this reason, when starting from this angle of oscillation of the hinge, the driving surfaces 32 ', 32' 'cause the slide 26 to move from the previously mentioned extended position to the contracted position, resulting in a wide arc of deceleration for the hinge.
    [057] From the previous description it becomes evident that the decelerated hinge according to the present invention has a deceleration device configured in a suitable way to be associated with closing means that are centrally positioned in the hinge box; in addition, the deceleration device is simple to build and has components that can be easily assembled together.
    [058] The hinge according to the present invention is susceptible to numerous modifications and variations falling within the scope of the inventive concept; in addition, all construction details can be replaced by technically equivalent ones.
