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.
• figure 1 three-dimensional view of the hinge according to the invention in its first embodiment
• figure 2 section of the hinge mounted on a door and a jamb in the fully closed position in its first embodiment
• figure 3 three-dimensional view of the hinge according to the invention in its second embodiment
• figure 4 three-dimensional exploded view of the hinge according to the invention of its second embodiment
• figure 5 three-dimensional view of the second adjustable body (8)
• figure 6 front view of the second adjustable body (8) with A-A section indicated figure 7: A-A section of the second adjustable body (8)
• figure 8 section of the hinge in its second embodiment mounted on a door and a jamb in the fully closed position.
• the present invention relates to a concealed hinge (100) for furniture doors and/or doors.
• 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).
• 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.
• 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.
• 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.
• 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).
• 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.
• 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).
• 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).
• 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)."
• 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).
• 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.
• 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.
• 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.
• 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.
• 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).
• 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.
• 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.
• 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).
• 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).
• 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).
• 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.
• 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).
• 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).
• 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).
• 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).
• 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.
• 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).
• 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).
