    "POLIVALENT ARTICULATED SUPPORT FOR FURNITURE DOORS" FIELD OF THE INVENTION
    This invention concerns a multi-purpose articulated support
    5 for furniture doors, those used in doors that beat vertically (around a horizontal axis) and are designed to keep the door in any intermediate opening position, without risk of closing or opening (depending on the case ) suddenly and may cause damage to the user, the furniture,
    10 to objects contained therein, or to other external objects close to it; At the same time, these supports allow a smooth and effortless handling of the door in one way or another, based on compensating the weight of the door by excess or by default depending on whether the opening is ascending or descending. 15 STATE OF THE PREVIOUS TECHNIQUE
    At present and as a reference to the state of the art, it is usual and known to use polyvalent articulated supports for furniture doors designed to keep the door in any intermediate opening position, without risk of
    20 to close or open (depending on the case) at once. This kind of swinging doors around a horizontal axis receives two different denominations; lift doors, when they are vertical doors with pivot axes on their upper edge (for example, a closet attic), or when they are
    25 horizontal doors with pivot axis at the rear edge (for example, a refrigerator chest); and swing doors; when they are vertical doors with axis of rotation in their inferior edge (for example a furniture-bar). In lifting doors (that open upwards) a support
    30 articulated must allow to open without more effort than is necessary to overcome the weight of the door and must retain it in any opening position when the lifting action on the part of the user ceases; retention that is performed automatically by an antagonistic action exerted by a clutch device
    35 which compensates in excess the weight of the door so that with a slight effort on the part of the user the closing of the door can be verified smoothly; The clutch device has the possibility of regulating its antagonistic action depending on the weight of the lifting door.
    5 However, when it comes to swing doors (which open downwards), the operation must be reversed, that is, in the opening the door weight must be compensated by default, so that it does not fall suddenly and, nevertheless , can continue to open with a slight effort applied by the user; and in the
    10 close the user must only overcome the weight of the door without other antagonistic action. Therefore, an articulated support for lift doors is not suitable for swing doors, and vice versa. According to a typical constitution, a support
    15 articulated for lifting doors consists of two arms, first and second, which have two free ends provided with means for mooring the door and the furniture, and at its other end they form an articulation composed of respective first and second articulation heads, by a lid that with interposition
    20 of the second articulation head is permanently coupled in rotation with the first articulation head, by a friction brake, by a rotation axis and by tensioning means capable of selectively varying the frictional effort exerted by this brake.
    In response to this typical constitution, an articulated support for raised doors is known in which the clutch device is based on the fact that the second articulation head has an internal configuration with two axes of rotation; one, coaxial with the axis of rotation and with that of a wheel externally
    30 toothed which is housed in this second articulation head and is rotatably connected with the friction brake; and the other, which refers to a teeth made only in a small internal area of the second articulation head, whose teeth are conjugated to that of said gear wheel and have a smaller radius
    35 with respect to this second axis of rotation which is equal to that of the wheel
    toothed with respect to the axis of rotation. All this, in such a way that (considering that the second arm is tied to the door and that at the closing it descends closing the angle with the first arm) the weight of the door itself carries the mechanism of the position of free rotation to the coupling position in which the toothed area of the second articulation head engages or engages with the gearwheel; with which to lower the door towards its closing, it will be necessary for the user to press lightly with an effort that, added to the weight of the door, manages to overcome the antagonistic effort for which the friction brake has been regulated. On the other hand, when opening, it is enough to start the maneuver so that the second arm moves radially separating the second axis of rotation from the axis of rotation and producing the consequent disengagement of the teeth that allows the opening in ascent
    15 of the door just by winning the weight of it.
    Obviously, if it were to apply this support to a hinged door, it would open only if it were not held by the user and, instead, the frictional antagonist effort would have to be overcome to be able to close it.
    20 EXPLANATION OF THE INVENTION AND ADVANTAGES In the face of this state of affairs, the present invention refers to polyvalent articulated support for furniture doors, in which there are at least two coaxial friction brakes with the axis of rotation, between the faces
    Adjacent friction brakes an inter-disk washer that remains motionless with respect to one of the first or second arms during the relative movement of the first and second arms; said friction brakes having an annular configuration of smooth stepped periphery which is defined by a first
    30 annular sector, which has free rotational adjustment with respect to the virtual cylinder corresponding to the smaller radius of a crown gear in the inner circular wall of the second articulation head, and by a second ring sector of smaller radius that delimits a hollow crown with said toothed crown annular sector; and because it exists
    35 a swinging ratchet of width width noticeably
    similar to the sum of the thicknesses of the existing friction brakes, an arc-circular tilt ratchet housed within said annular sectorial recess and externally incorporates a section of peripheral toothing which is conjugated to that of the crown
    5 toothed of the second arm and incorporating means for selective coupling / decoupling between such partial peripheral teeth and toothed crown, which are conjugated to other means incorporated in the friction brakes dependent only on the direction of rotation of said friction brakes.
    10 Thanks to this configuration, the support is applicable to elements of greater mass and / or height, since the resistant torque increases due to the use of at least two friction brakes in the joint formed by the first and second articulation heads; heavy duty bracket pair that is in charge of
    15 keep the furniture door to which it is attached in an intermediate position without allowing the closing or abrupt opening of the same. In addition, the use of inter-disc washers between each pair of friction brakes, which remain fixed during the movement with respect to the first arm, allows
    20 friction brakes perform their function independently of each other, and in addition to improving the reliability and durability of these brackets, since direct friction between adjacent faces of friction brakes is avoided and provides a more suitable friction surface for those brake faces,
    25 obtaining a longer useful life of the support. Another feature of the invention is that there is a transverse pin, the length of which is substantially similar to the sum of the thicknesses of the friction brakes, between the concave side of the swinging ratchet and the friction brakes, said pin
    30 transverse is located in the housing recesses existing in the second annular sectors of the friction brakes and positioned between the front barriers and the rear barriers that incorporate the friction brakes in the second annular sectors.
    Thanks to this configuration, the mounting of the support is facilitated and improved. This pin is responsible for performing the coupling / decoupling maneuver of the peripheral toothed section of the ratchet with the toothed crown that incorporates the head of
    5 second joint. Being a mechanism that requires great precision and that is based on the friction between the different elements, it is convenient that during the assembly of the elements the elements are handled with the greatest possible hygiene, avoiding the contamination of said elements with fatty substances that
    10 significantly alter the braking quality and cause that the necessary resistant torque cannot be reached. The introduction of a pin between the concave face of the ratchet and the contour recesses of the friction brakes to perform the function of coupling and decoupling the partial teeth of the ratchet
    15 with the crown gear is a solution that requires less manipulation of the elements, compared to other solutions such as the use of springs or similar.
    Another feature of the invention is that the existence of first and second end washers is provided,
    20 said first end washer being placed between the inner face of the first articulation head and the outer face of the first friction brake, and said second extreme washer being placed between the inner face of the cover and the outer face of the second friction brake.
    25 Thanks to this configuration, the external faces of the friction brake assembly contact the surfaces of these external washers during operation, so that friction is carried out against them instead of against the finishes of the inner face of the cover and of the inner face of the
    30 head first joint. In general, the finishes of the surfaces of the cover and of the first and second arm are not smooth enough and may have imperfections that can be detrimental to friction brakes, causing both irreparable damage and malfunction of the brakes. This
    Thus, with the use of external washers, it is expected to increase the reliability and durability of the support. Another feature of the invention is that repetition in number and size of friction brakes with their
    5 respective inter-disk washers to identify the articulated support in destination, configuration or size with the force to counter lifting and / or folding elements.
    Thanks to this characteristic, it is possible that the articulated support can be used in furniture elements that
    10 require a greater resistant torque, since the friction surface is increased, individualizing the support with the number of friction brakes required by each element. DRAWINGS and REFERENCES

    With regard to the drawings and references listed above, a preferred embodiment 25 of the object of the invention is illustrated in the attached drawings, referring to polyvalent articulated support for hinged furniture doors or raised interchangeably, of the supports consisting of two arms, first (1) and second (2), which have two free ends provided with means for mooring the door and the furniture, and at its other end they form a rotating joint composed of respective first articulation heads (3) and second (4) and by a cover (5), articulation that incorporates friction brakes (6a) (6b) with a rotation axis (7) and by means of tensioning means (8-9) capable of selectively varying the effort of friction exerted by these brakes of
    35 friction (6a) (6b).
    An object of the invention is a particular constitution of a device capable of coupling and decoupling the action of the friction brakes (6a) (6b) in relation to the relative direction of rotation of the first (1) and second (2) arms. . To do this, as
    5 is seen in Figure 1, there is a support in which there are at least two friction brakes (6a) (6b) coaxial with the rotation axis (7), being placed between the adjacent faces of the friction brakes (6a ) (6b) an inter-disk washer (18) that remains motionless with respect to the first arm (1) during movement
    10 relative of the first (1) and second (2) arms; said friction brakes (6a) (6b) having an annular configuration of smooth stepped periphery which is defined by a first annular sector (11), which has free rotational adjustment with respect to the virtual cylinder corresponding to the smallest radius of a toothed crown (10 ) in the
    15 internal circular wall of the second articulation head (4), and by a second annular sector (12) of smaller radius that delimits with said toothed crown (10) an annular sectorial recess (13); and because there is a swinging ratchet (14) of amplitude in width substantially similar to the sum of the thicknesses of the
    20 existing friction brakes (6a) (6b), swinging ratchet (14) of an arc-circular shape housed within said annular sectorial recess (13) and externally incorporating a section of peripheral toothing (15) which is conjugate of the the toothed crown (10) of the second arm (2) and incorporating means for the
    25 selective coupling / decoupling between such partial peripheral teeth (15) and crown gear (10), which are conjugated to other means incorporated in the friction brakes (6a) (6b) dependent only on the direction of rotation of said friction brakes ( 6a) (6b).
    30 The friction brakes (6a) (6b) have a first annular sector (11) that rotates freely with the virtual cylinder corresponding to the smallest radius of the toothed crown (10). The use of at least two friction brakes (6a) (6b) between which an inter-disk washer (18) is interposed allows
    35 use of articulated supports in furniture elements that require a greater resistant torque to be able to stay in intermediate positions during opening or closing. The inter-disk washer (18) remains fixed with respect to the first arm (1) during the relative movement of the first arms (1) Y
    5 seconds (2), giving friction brakes independence (6a) (6b).
    The toothed crown (10) is formed by rotationally asymmetric teeth that have a major paratangential side (16) and a minor para-radial side (17), as
    10 looks at the coupling / decoupling details of Figures 5b and 6b. Observing Figures 3 and 4, it is seen as the first annular sector (11) of the friction brakes (6a) (6b) at one of its ends, forming a first radial front outwards.
    (19) which is oriented in confrontation with the second front
    15 radial (24) of the swinging ratchet (14) and said first radial front (19) extends until reaching the periphery of the second annular sector (12); said second annular sector (12) has peripherally protruding a pin (20) defined between a tangential side (21) and two substantially radial sides
    20 (22, 23), said tangential side has an intermediate radius between those of the first (11) and second (12) annular sectors, and said substantially radial sides are designated as forward
    (22) and rear (23) according to its smaller or greater distance to the first radial front (19) of the first annular sector (11); said swinging ratchet 25 (14), at one of its ends, forms a second radial front inwardly (24), which is conjugated to said first radial front (19) of the first annular sector (11). Other details constituting the swinging ratchet (14) are that (figures 3, 4, 5a, 5b, 6a and 6b): it has at its end an active functional configuration formed by the front oblique plane (26) that faces and is parallel to the front radial side (22) of the pin (20) when the swinging ratchet (14) is in its position closest to the axis of rotation (7); and in the position of the swinging ratchet (14) furthest from the axis of rotation (7), said
    The front oblique plane (26) has its end at a radial distance somewhat smaller than that of said front radial side (22) of the stud (20); said tilting ratchet (14) forms an oblique rear plane (27) facing said rear radial side
    (23) of the stud (20) and is parallel to it when the ratchet
    5 swingarm (14) is in its position furthest from the axis of rotation (7); in the position of the swinging ratchet (14) furthest from the axis of rotation (7), said rear oblique plane (27) has its end at a radically smaller distance than that of said rear radial side (23); at its opposite end to the radial front
    10 (24), on the concave side of said tilting ratchet (14) is the transverse pin (29) located in the housing recess (30) which has the second annular sector (12) of the friction brakes (6a) (6b) at the end opposite the first radial front (19), said cross pin (29) being
    15 between the front (31) and rear (32) barriers emerging from said housing recess (30) of the second annular sector (12) and designated as front (31) and rear barrier
    (32) according to its distance to said first radial front (19) of the second annular sector (12).
    The operation of this device is illustrated by figures 5a, 5b, 6a and 6b: by rotating the first arm (1) counterclockwise according to figure 5a due to the tensioning means (8-9) the friction brakes ( 6a) (6b) are dragged so that by wedging between the rear side (23) of the
    25 stud (20) and the oblique rear plane (27) of the swinging ratchet (14); this ratchet (14) couples its partial peripheral teeth (15) with a corresponding section of the crown gear (10) while the first (19) and second (24) radial fronts of said first annular sector (11) and tilting ratchet (14) butt
    30, from which moment the continuation of the rotation of the first arm (1) can only be carried out by overcoming the antagonistic action of the friction brakes (6a) (6b), which are trapped with the appropriate force (regulated with the tensioning means 8-9) between the first arm itself (1) and the cover (5); from
    35 so that this mutual stop between the radial fronts first
    (19) And second (24) establishes a limitation to the wedging action that begins a little earlier between the rear radial side (23) of the stud (20) and the oblique rear plane (27) of the swinging ratchet (14); These two coupling and 5-stop effects favor coupling reliability and provide robustness in the action against friction brakes (6a) (6b). Starting from this coupling position, at the beginning of the counter-clockwise rotation (figure 6b) the front radial side (22) of the pin (20) reaches the tip of the front oblique plane (26) of the swinging ratchet 10 (14) forcing it to disengage from the crown gear (10). In the angular relative displacement of the swinging ratchet (14) with respect to the friction brakes (6a) (6b), the transverse pin (29) located between the concave side of the end opposite the second radial front (24) of the
    15 tilting ratchet (14) and housing recesses (30) provided at the opposite end to the first radial front (19) of the second annular sector (12).
    The toothed crown (10) of the second arm (2) continuously governs the angular displacement of the swinging ratchet 20 (14) with respect to the friction brakes (6a) (6b) and there is a permanent contact between the swinging ratchet (14) and the crown gear
    (10) both in the direction of rotation corresponding to the coupled ratchet position (with friction brake antagonistic action); as, in the decoupled ratchet position (no action
    Friction brake antagonist); the extreme location of the cross pin (29) and away from the partial peripheral teeth
    (15) existing on the convex side of the swinging ratchet (14); makes the contact of the crown in the direction of rotation corresponding to the position of the swinging ratchet (14)
    30 toothed (10) is with the smooth area that exists on the convex side of the swinging ratchet (14) because it is located close to the transverse pin (29) and (as seen in Figure 6b) the partial peripheral teeth (15) does not rub the crown (10) and avoid both noise and tooth wear.
    35 The operation of this coupling device is the same in
    anywhere in the 3600 of the joint; so that, for example, the counterclockwise rotation of the first arm (1) corresponds to the coupled state, in the first 1800s this coupling takes place with the first arm (1) moving away from the second arm (2), while in the 1800s the coupling takes place with rotational approach of the first arm (1) to the second (2); the same can be said about the decoupled state with clockwise rotation. In other words, this means that the same articulated support can be
    10 used interchangeably for lifting and folding doors by working only in the first or second 1800 of the joint.
    Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essence of this invention.
