Definitions
- the invention relates to a concealed hinge for furniture doors and doors and windows; it finds application in the field of furnishings as well as interior and exterior doors.
- the technical field of interest in the present invention concerns in particular concealed hinges, which allow the furniture door or the door to be opened up to an angle of approximately 180° in relation to an angle of 0° when the door is closed in relation to the jamb or upright of the door frame.
- the hinges for the door sector and particularly of furniture comprise two bodies, one fastened to the jamb and one to the door leaf, said bodies joined together by one or more connecting arms.
- hinges are also known that are fitted with means of adjustment along the three Cartesian axes as described for example in EP2110502 (Ceam), in EP2390446 (Otlav) or in DE10239446 (Simonswerk), for the purpose of allowing - once mounted on the door and on the jamb - small adjustments to allow optimal opening of the door, without the possibility of interference with the structure of the actual furniture.
- the known concealed hinges generally have one body recessed on the flat of the jamb, that is at right angles to the main face of the actual jamb, while the other body is recessed onto the door edge, that is, on the surface which represents the thickness of the actual door.
- offset hinges are also known, which are applicable in installations where in the closed hinge position the recessed bodies of the actual hinge are not aligned.
- Such a type of hinge is described in DE102011000150 (Simonstechnik) where in fact an offset hinge is described, not adjustable along any of the Cartesian axes and which has guide paths inside the actual hinge along which the pins of the articulating arms slide, said paths whose characteristic is that they are not parallel to any reference axis and in certain cases are in the shape of an arch, thereby allowing, according to the drafter, the dimensions of one of the two fastening elements of an offset hinge to be reduced, in particular the dimensions of the element that is intended to be fastened to the jamb.
- a first technical problem is represented by the fact that the current concealed hinges, that is, in EP2110502 (Ceam), in EP2390446 (Otlav) or in DE10239446 (Simonswerk), due to the way they are structured, require that the slots in which both hinge bodies will be housed, must necessarily be made at a limited distance from the outer edge of the jamb or the door leaf, this distance generally being around 4 mm.
- This technical necessity stems from the need to combine a smooth and non-interfering movement of the door with the reduced gap between leaf and jamb during closing and opening, said gap being enforced by dimensional factors of the hinge itself.
- the present invention relates to a concealed hinge for furniture doors and doors and windows, comprising two fixed bodies that will be recessed in the jamb and in the openable door, two arms connecting the two bodies, where each of the two arms has one end pivoted to one of the two bodies while the opposite end is engaged in a guide path of the other body, of which at least one of said guide paths is not straight.
- a first object of the present invention is to make a concealed hinge for furniture doors and/or doors, which due to its technical characteristics is able to be installed in a slot made in the door and in the jamb, said slot made with an external wall - the thickness of which is shown in figures 2 and 8 by the dimension Q5 - a thickness that is greater than the state required by known hinges of prior art, although maintaining a reduced gap between door and jamb in operating conditions of full opening and closing of the hinge.
- a second object of the present invention is to make a concealed hinge for furniture doors and/or doors characterised in that it reduces the dimensions, particularly the width and depth, of the bodies of the same hinge that will be recessed in the jamb and the door, without prejudice to the performance in terms of strength, duration and therefore reliability and smoothness of movement of the same hinge, or to the stability of the hinge in the stage of complete closure of the same.
- Another object of the present invention is to make a concealed hinge for economical furniture doors and/or doors and which provides an alternative to prior art.

Description
Description of the patent having as its title:
CONCEALED HINGE FOR FURNITURE DOORS AND DOORS
[0001] The invention relates to a concealed hinge for furniture doors and doors and windows; it finds application in the field of furnishings as well as interior and exterior doors.
Scope and prior art
[0002] In prior art hinges are known that allow the opening and closing of furniture doors and hinges for the opening and closing of doors and therefore within the scope of the technical sector of doors and windows.
[0003] The technical field of interest in the present invention concerns in particular concealed hinges, which allow the furniture door or the door to be opened up to an angle of approximately 180° in relation to an angle of 0° when the door is closed in relation to the jamb or upright of the door frame.
[0004] In prior art, the hinges for the door sector and particularly of furniture comprise two bodies, one fastened to the jamb and one to the door leaf, said bodies joined together by one or more connecting arms.
[0005] In the technical sector of concealed hinges, hinges are also known that are fitted with means of adjustment along the three Cartesian axes as described for example in EP2110502 (Ceam), in EP2390446 (Otlav) or in DE10239446 (Simonswerk), for the purpose of allowing - once mounted on the door and on the jamb - small adjustments to allow optimal opening of the door, without the possibility of interference with the structure of the actual furniture.
[0006] Further to the aim of providing support for the door and simultaneously guaranteeing a smooth swivelling movement of the same in opening and closing, at the same time combining the aesthetic factor with the purpose of limiting the overall size of the actual hinge inside the furniture to a minimum, mechanisms have been actuated, the so-called concealed hinges, that is, hinges whose parts are recessed into the furniture frame and the furniture door or the door and the jamb, there being - in this specific prior art - only portions of the arms connecting the two bodies of the same hinge protruding beyond the outer edge of the door or the jamb.
[0007] The known concealed hinges generally have one body recessed on the flat of the jamb, that is at right angles to the main face of the actual jamb, while the other body is recessed onto the door edge, that is, on the surface which represents the thickness of the actual door.
[0007bis] Concealed hinges called offset hinges are also known, which are applicable in installations where in the closed hinge position the recessed bodies of the actual hinge are not aligned. Such a type of hinge is described in DE102011000150 (Simonswerk) where in fact an offset hinge is described, not adjustable along any of the Cartesian axes and which has guide paths inside the actual hinge along which the pins of the articulating arms slide, said paths whose characteristic is that they are not parallel to any reference axis and in certain cases are in the shape of an arch, thereby allowing, according to the drafter, the dimensions of one of the two fastening elements of an offset hinge to be
reduced, in particular the dimensions of the element that is intended to be fastened to the jamb.
[0007ter] A hinge is also known that is described in EP1754848 (Simonswerk), which does not allow optimal adjustments and moreover not along all the Cartesian axes and which presents guide paths fully curved in an "S" shape as indicated in paragraph 21 of the text of the same patent.
Drawbacks and problems of the known art
[0008] In the technical sector of concealed hinges, prior art presents a series of drawbacks and technical problems that the present invention intends solving.
[0009] A first technical problem is represented by the fact that the current concealed hinges, that is, in EP2110502 (Ceam), in EP2390446 (Otlav) or in DE10239446 (Simonswerk), due to the way they are structured, require that the slots in which both hinge bodies will be housed, must necessarily be made at a limited distance from the outer edge of the jamb or the door leaf, this distance generally being around 4 mm. This technical necessity stems from the need to combine a smooth and non-interfering movement of the door with the reduced gap between leaf and jamb during closing and opening, said gap being enforced by dimensional factors of the hinge itself.
[0010] This circumstance is often remedied by the technician resorting to increasing the thickness between the external wall of the recess slot and the outer edge of the jamb or door, being obliged, however, to bevel and/or radius the sharp edges of the external side face of the jamb and the door to avoid interference between door and jamb during operation, this being a
circumstance, however, that reduces the strength of said bevelled and/or radiused edges, making it possible for there to be breakages or chipping of the material of which the actual furniture is made. Whereas in other cases architrave panels are installed as indicated in DE102011000150 (Simonswerk) to offset the installation of the element flush with the jamb, being obliged to create an offset hinge.
[OOlObis] Also with regard to the guide paths described in the hinge forming the subject matter of patent DE102011000150 (Simonswerk), in the opinion of the drafter, since for their whole length they must necessarily have a certain inclination in relation to the Cartesian axes of reference, whether the path made in the element applied onto the door or the one made in the element applied onto the jamb and again, whether in the 45° version or the arched version, they do not have a straight portion of path parallel to any axis of reference and in particular provide for the initial portion of the guide path nearest the bottom of the housing element of the frame (6) to be totally curved - being a portion of arch - and even more so for it not to be parallel to the Y axis of reference indicated in patent DE102011000150 (Simonswerk),
It is also pointed out that the excessive inclination of the guide path of the jamb in both versions illustrated in patent DE102011000150 (Simonswerk) in which the initial and final position in any case are located along a line at almost 45° does not allow the depth of the element that is installed on the jamb to be reduced, at variance with the latest demands of the furniture industry.
[0011] A further problem of known prior art also concerns the application of concealed hinges to plasterboard or dry walls; insistence on having such reduced thickness of material enclosing the hinge slot results in it being exposed to breakages, even immediately upon mounting the hinges or to wear from the very first use.
[0012] Lastly, another problem of known prior art lies in the fact that the depth of the hinge body which must be accommodated in the jamb is too great for it to be mounted on jambs of limited thickness, since the path of the ends of the arms, which slide in suitable guides made in the hinge bodies, must have dimensions that cannot be avoided in order to guarantee 180° opening of the same hinge.
[0013] A similar circumstance as described in the preceding paragraph also concerns the width of the bodies of current hinges, which cannot fall to below established tolerances.
Summary of the invention
[0014] The present invention relates to a concealed hinge for furniture doors and doors and windows, comprising two fixed bodies that will be recessed in the jamb and in the openable door, two arms connecting the two bodies, where each of the two arms has one end pivoted to one of the two bodies while the opposite end is engaged in a guide path of the other body, of which at least one of said guide paths is not straight.
Objects of the invention
[0015] A first object of the present invention is to make a concealed hinge for furniture doors and/or doors, which due to its technical characteristics is able to be installed in a slot made in the door and in the jamb, said slot made with an external wall - the thickness of which is shown in figures 2 and 8 by the dimension Q5 - a thickness that is greater than the state required by known hinges of prior art, although maintaining a reduced gap between door and jamb in operating conditions of full opening and closing of the hinge.
[0016] A second object of the present invention is to make a concealed hinge for furniture doors and/or doors characterised in that it reduces the dimensions, particularly the width and depth, of the bodies of the same hinge that will be recessed in the jamb and the door, without prejudice to the performance in terms of strength, duration and therefore reliability and smoothness of movement of the same hinge, or to the stability of the hinge in the stage of complete closure of the same.
[0017] Lastly, another object of the present invention is to make a concealed hinge for economical furniture doors and/or doors and which provides an alternative to prior art.

Description of the preferred embodiments
[0019] With particular reference to the detailed but non-exhaustive figures given, the present invention relates to a concealed hinge (100) for furniture doors and/or doors.
[0020] By way of example, with particular reference to figure 2, a system of reference X, Y, Z is used, with axis of reference Z vertical and parallel to the axis of rotation of the door (200) in relation to the jamb (300), axis of reference X which identifies the full depth of the two bodies (1,2) of the hinge as well as the slots that will house said bodies (1,2) on the jamb (300) and on the door (200), and axis of reference Y which completes the indicated Cartesian group of three (cf. fig. 2).
[0021] The concealed hinge (100) in the embodiment shown in figures 1 and 2 has a first body (1) destined to be housed in a special slot made in the edge of door (200), that is, on the smaller surface of the door (200) as indicated in figure 2, and a second body (2) destined to be housed in a special slot made on the flat of the jamb (300), that is, on the larger internal surface of the jamb (300) as shown in figure 2.
[0022] The first body (1) has a pair of slotted housings (12) projecting from the opposite side faces (13) of the first body (1); said slotted housings (12) lie along the axis of reference Z and allow the movement and the adjustment of the hinge (100) along the axis of reference Z fastening it with conventional screws.
[0023] The first body (1) also has holes (37) aligned with each other along the direction of the axis of reference Z designed to receive a pin (5) designed to pivot the end of a first arm (6) which connects the first body (1) to the second body (2) with a pivot-sliding movement.
[0024] The first body (1) has a pair of equal and opposite first guides (36) running straight and parallel to the axis of reference X with particular reference to figure 2; a pair of opposite teeth (71), made at the free end of the second arm (7), are obliged to slide inside said opposite first guides (36) from a fully open position of the hinge (100), in which the teeth (71) are placed in a position at the top of the opposite first guides (36) in relation to the increasing direction of the axis of reference X, to a fully closed position of the hinge (100) in which the teeth (71) are placed in the exact opposite position in relation to the increasing direction of the axis of reference X of the opposite first guides (36), and therefore in the
exact opposite position compared to that of the fully open position of the hinge (100).
[0025] The second body (2) also has holes (82) aligned with each other along the direction of the axis of reference Z designed to receive a second pin (5) designed to pivot the end of a second arm (7) which connects the second body (2) to the first body (1) with a pivot-sliding movement.
[0026] The first arm (6) is also pivoted to the second arm (7) through another pin (51) and a bearing (52), said pin (51) parallel to the axis of reference Z and which allows the relative rotation between the two arms (6,7).
[0027] The second body (2) has a pair of opposite second guides (83); a pair of opposite teeth (61) of the first arm (6) are obliged to slide inside said opposite second guides (83) from a fully open position of the hinge (100), in which the teeth (61) are placed in a position at the top in relation to the increasing direction of the axis of reference X of the opposite second guides (83), to a fully closed position of the hinge (100).
[0028] With particular reference to figure 2 the opposite second guides (83) consist of a curving path comprising a first straight portion parallel to the X axis, said first straight portion near the bottom of the second body (2), and comprising a curved intermediate portion similar to an open letter C adjacent to the first straight portion and adequately connected thereto, in which said intermediate portion deviates from the ideal line joining the exact opposite positions of the curving path inside the second guides (83)." In the embodiment the path of each of the second guides (83) is curved, that is, it comprises curved and straight
portions, and the curved intermediate portion is made with concavity facing the decreasing direction of the axis of reference Y (cf. figure 2 and figure 8).
[0029] All the positions taken by the teeth (61) when they travel along the second guides (83) recreate a gradual curved geometry and not a broken line, this being a condition which guarantees the smooth movement of the hinge (100) in all its operating stages.
[0030] The curving line of the path of the second guides (83) can differ in reference to the initial and final positions, but always has a more or less pronounced deviation of the intermediate position from the ideal line joining the initial and final position, thereby making it possible to change - in particular reducing - the dimension, designated by Ql in figure 2 and figure 8, of the second body (2), so as to adapt it to the door or jamb in which it will be installed and at the same time making it possible to increase the dimension Q5 of figure 2 and figure 8, that is, the external wall of the recess slot for the hinge (100) on the door (200) and on the jamb (300), therefore reinforcing the critical points against possible deterioration of the material.
[0031] In a second embodiment shown in figures 3, 4, 5, 6, 7, 8, the invention provides that the concealed hinge (100) has a first body (1) comprising a first cup (10) and an adjustable first body (3), said first cup (10) intended to be housed in a special slot made in the door edge (200), that is, on the smaller surface of the door (200) as shown in figure 8, and a second body (2) comprising a second cup (20) and an adjustable second body (8), said second cup (20) intended to be
housed in a special slot made in the flat of the jamb (300), that is, on the larger internal surface of jamb (300) as shown in figure 8.
[0032] The first cup (10) has a pair of slotted housings (12) projecting from the opposite side faces (13) of the first cup (10); said slotted housings (12) lie along the axis of reference Z and permit the movement and adjustment of the hinge (100) along the axis of reference Z fastening it with conventional screws.
[0033] Inside the first cup (10) in the relative housing is inserted an adjustable first body (3) with two crests (31) projecting from the opposite side faces (33) which lie along the direction of the axis of reference X and which are designed to slide along the direction of the axis of reference X inside joined seats (11), this sliding allowing the adjustment of the installed hinge along the axis of reference X, with particular reference to figure 8.
[0034] The adjustable first body (3) also has a flared hole (32) designed to accommodate a screw (4) whose vertical movement in relation to the adjustable first body (3) along the axis of reference X is prevented by a pair of pins (53) inserted parallel to the Y axis in the relative holes (34) made on the side surface (35) of the adjustable first body (3), said pins (53) designed to hold back the head (41) of the screw (4) from possible movements along the axis of reference X in relation to the adjustable first body (3). Fully aligned with the axis of reference X in relation to the hole (34,) a threaded hole is made on the cup (10) into which the screw (4) is screwed, the degree of tightening of which guarantees the adjustment of the depth of the adjustable first body (3) inside the first cup (10), therefore allowing the adjustment of the hinge (100) along the X axis.
[0035] The adjustable first body (3) has a pair of equal and opposite first guides (36) running straight and parallel to the axis of reference X; a pair of opposite teeth (71), made at the free end of the second arm (7), are obliged to slide inside said opposite first guides (36) from a fully open position of the hinge (100), in which the teeth (71) are placed in a position at the top of the opposite first guides (36) in relation to the increasing direction of the axis of reference X, to a fully closed position of the hinge (100) in which the teeth (71) are placed in the exact opposite position in relation to the increasing direction of the axis of reference X of the opposite first guides (36), and therefore in the exact opposite position compared to that of the fully open position of the hinge.
[0036] The adjustable first body (3) also has holes (37) aligned with each other along the direction of the axis of reference Z designed to receive a pin (5) designed to pivot the end of a first arm (6) which connects the adjustable first body (3) to the adjustable second body (8), accommodated inside the relative housing in the second cup (20), with a pivot-sliding movement.
[0037] The adjustable second body (8) has a pair of slotted housing (81) parallel to the axis of reference Y, made on the opposite faces (84) of the adjustable second body (8) inside each of which is inserted a screw (42) and a washer (43), each said screw (42) is screwed into a threaded hole not shown in the figures and made on second cup (20). By loosening the screws (42) the adjustable second body (8) is released from the second cup (20) allowing the position of the adjustable second body (8) to change in relation to the second cup (20) along the axis of reference Y within a certain range defined by the shape of the slotted
housings (81) which move parallel to the axis of reference Y inside seats (22) made inside the second cup (20).
[0038] The adjustable second body (8) also has holes (82) aligned with each other along the direction of the axis of reference Z designed to receive a second pin (5) designed to pivot the end of a second arm (7) which connects the adjustable second body (8) to the first body (3), accommodated inside the relative housing in the first cup (10), with a travel-sliding movement.
[0039] The first arm (6) is also pivoted to the second arm (7) through another pin (51) and a bearing (52), said pin (51) parallel to the axis of reference Z and which allows the relative rotation between the two arms (6,7).
[0040] The adjustable second body (8) has a pair of opposite second guides (83); a pair of opposite teeth (61) of the first arm (6) are obliged to slide inside said opposite second guides (83) from a fully open position of the hinge (100), in which the teeth (61) are placed in a position at the top in relation to the increasing direction of the axis of reference X of the opposite second guides (83), to a fully closed position of the hinge (100) in which the teeth (61) are placed in the exact opposite position in relation to the increasing direction of the axis of reference X of the opposite second guides (83).
[0041] With particular reference to figure 5 the opposite second guides (83) consist of a curving path comprising a first straight portion parallel to the X axis, said first straight portion near the bottom of the adjustable second body (8), and comprising a curved intermediate portion similar to an open letter C adjacent to the first straight portion and adequately connected to it, in which said
intermediate portion deviates from the ideal line joining the exact opposite positions of the curved section inside the second guides (83). In the embodiment the path of each of the second guides (83) is curved, that is, it comprises curved and straight portions, and the curved intermediate portion is made with concavity facing the decreasing direction of the axis of reference Y (cf. figure 2 and figure 8).
[0042] All the positions taken by the teeth (61) when they travel along the second guides (83) recreate a gradual curved geometry and not a broken line, this being a condition which guarantees the smooth movement of the hinge (100) in all its operating stages.
[0043] The curving line of the path of the second guides (83) can differ in reference to the initial and final positions, but always has a more or less pronounced deviation of the intermediate position from the ideal line joining the initial and final position, thereby making it possible to change - in particular reducing - the dimension, designated by Ql in figure 2 and figure 8, of the second body (2), so as to adapt it to the door or jamb in which it will be installed and at the same time making it possible to increase the dimension Q.5 of figure 2 and figure 8, that is, the thickness of the external wall of the installation slot of both bodies (1,2) of the actual hinge, therefore reinforcing the critical points against possible deterioration of the material with which they are made.
[0044] In a third embodiment the invention provides that a circular housing is made on the adjustable second body (8) to accommodate a cam (9) with a tooth (91) designed to engage with a longitudinal seat parallel to the axis of reference
Y and made on the bottom of the second cup (20), this being a condition which would allow the position of the adjustable second body (8) to be adjusted in the direction of the axis of reference Y in relation to the second cup (20), by turning the cam (9) once the screws have been loosened (42).
[0045] In a fourth embodiment also the first guides (36) present the same curving path of the second guides (83) described in the first embodiment, that is, in a further embodiment both the first guides (36) and the second guides (83) have the same curving path as the second guides (83) described in the first and second embodiment, therefore reducing the dimension both of the first body (1) and of the second body (2).
[0046] The concealed hinge forming the subject matter of the invention is therefore made according to all that is described in the claims from No. 1 to No.
