Definitions

  • the present invention relates to the field of hinges for doors of pieces of furniture and the like.
  • the hinge of the invention is of the so-called “single-pin” type, wherein the two wings of the hinge (one connected to the shoulder of the piece of furniture and the other to the door) are rotatingly associated around a single pin which defines the rotation axis of one with respect to the other.
  • the hinges referred to are those with an "outer" single pin, i.e. those in which the pin - when the hinge is assembled - is situated outside the piece of furniture, in an accessible position also when the door is closed.
  • the present invention can in any case also be applied with an "inner" single-pin hinge, i.e. those in which the pin - when the hinge is assembled - is situated inside the furniture, in a non-accessible position when the door is closed.
  • This hinge comprises a first element - or base - fixed to the wall (or shoulder) of the piece of furniture, a second element - or wing - fixed to the rotatable door and an intermediate element hinged to the base and destined for oscillatingly connecting the base to the wing;
  • the intermediate element of this hinge carries an adaptor which is inserted in a seat incorporated in the wing by means of a straight "drawer-type" sliding movement;
  • the adaptor is blocked by means of reciprocal engagement of a tooth provided on the adaptor with a recess and an abutment, provided on a lid hinged by means of a hinge along the edge of a fixing plate incorporated inside the wing so that it can be overturned from a closed position in contact with the fixing plate to an open position obtained by a rotation around the hinge ranging from a few degrees to 90 degrees.
  • hinges are extremely useful and widespread, the presence of the outer rotation pin, moreover, avoids occupying precious space inside the furniture and allows rotations of the door even greater than 180°.
  • the objective of the present invention is to overcome the drawbacks of the known art.
  • an objective of the present invention is to provide a single-pin hinge for pieces of furniture that has a dampened movement at least for a section of the overall rotation range.
  • a further objective of the invention is also to provide such a hinge also having a stable retaining position of the door.
  • the general idea at the basis of the present invention envisages damping the closing run of the door with respect to the wall of the piece of furniture using a damper; the closing run develops between an open position of the door and a closed position, in which the wall and the door have a substantially perpendicular arrangement; the invention provides the following steps:
  • the open position of the door is that in which the door does not close the piece of furniture: using this type of hinge, the door can be substantially positioned parallel to the wall (90° rotation) or even perpendicular to the wall (180° rotation) or more.
  • An idea at the basis of the invention is also to provide a single-pin hinge provided with a damper suitable for acting at least in correspondence with a terminal rotation phase of the door near said closed position.
  • a first object of the invention correspondingly relates to a single-pin hinge according to the first enclosed claim and a functioning method of said hinge according to the respective enclosed independent claim.
  • the single-pin hinge of the invention for fixing a door to a wall of a piece of furniture comprises
  • the damper is interposed between the intermediate element and the base and suitable for acting between the two, in correspondence only with a terminal rotation phase of the door close to said closed position.
  • the wing rotates without translating with respect to the base around said rotation axis (X).
  • the intermediate element can be coupled removably from the wing and contains an adapter suitable for being inserted in a seat, incorporated in the wing, by means of a straight sliding movement, said adapter being blockable in said seat by the reciprocal engagement of a tooth provided on said adapter with a recess and an abutment, provided on a lid hinged on the wing, said lid being tiltable from a closed position in which it blocks said adapter in the seat to an open position in which it releases said adapter from said seat.
  • the intermediate element is integral with the wing from which it extends, making the construction simpler on the whole and with a reduced cost of the hinge.
  • the intermediate element comprises a sleeve which surrounds and defines a seat of a pin coinciding with the rotation axis, the sleeve is integral with the rotation with the intermediate element and is provided with a first cam profile destined for cooperating with said damper.
  • the hinge comprises return and stable withholding means in a closed position of the door.
  • the return and stable withholding means comprise a second cam profile integral with the intermediate element, preferably positioned on said sleeve, at least one return and spring withholding element which protrudes from the base in the direction of the second cam profile so as to draw the door towards the closed position and firmly hold it in this position until an external force (e.g. following the action of the user) re-opens it.
  • the damper is incorporated in the base and extends towards the intermediate element.
  • the closing run develops between an open position of the door and a closed position, in which the wall and the door have a substantially perpendicular arrangement
  • the method comprises the following steps:
  • said method comprises the step of activating return and stable withholding means in a closed position of the door in a non-activated condition of the damper, i.e. in step a.
  • the closing run of the door is divided into three phases:
  • the enclosed figures show two non-limiting variants of a single-pin hinge indicated as a whole, in the two variants, with the reference numbers 1 and 10.
  • the two embodiments relate to outer single-pin hinges, but it should be understood that in other embodiments the pin can be internal, without being excluded from the scope of the invention.
  • the hinge 1 is generally used for fixing a door A to a wall P of a piece of furniture, as shown in figures 1 and 2 .
  • the hinge 1 is an outer single-pin hinge, as, as is known, it has only one rotation axis (pin) which is positioned, in a visible and accessible way, outside the volume of the furniture closed by the door A.
  • the hinge 1 comprises a base 2 and a wing 3, in addition to an intermediate element 4 which extends from the wing 3 and is hinged to the base 2.
  • the base 2 is fixed to the wall of the piece of furniture, whereas the wing 3 is fixed to the door; in practice and as a variant, their arrangement can be reciprocal.
  • the intermediate element 4 is destined for rotatingly connecting the base 2 to the wing 3 for making the door A rotatable with respect to the wall P of the piece of furniture around the single rotation axis X, coinciding and defined by the pin B of the hinge 1; it should be noted that in this hinge, the wing 3 rotates without translating with respect to the base 2 around the rotation axis X, very differently from the hinges in which articulation quadrilaterals are provided.
  • the door A moves rotatingly around the axis X between an open position ( figure 1 ) in which the base 2 and the wing 3 are, in this example, perpendicular, and a closed position of the door A ( figure 2 ) in which they are again perpendicular, but the door closes the cavity of the furniture; in this example, in fact, the hinge 1 allows a rotation of the door of about 180°.
  • the hinge 1 also comprises a damper 5 interposed between the intermediate element 4 and the base 2.
  • Said damper 5 is characteristically suitable for acting between the intermediate element 4 and the base 2 at least in correspondence with the terminal rotation phase of the door A close to the closed position, in order to obtain the advantages discussed above.
  • the damper 5, in this preferred embodiment, is a cylinder 51 with a stem 52, wherein the latter moves in the cylinder 51 in a damped way, for example thanks to oil, grease or the like which slow down its movement.
  • the damper 5 is interposed between the intermediate element 4 and the base 2 and one of its parts (cylinder or stem) is in contact with the intermediate element 4 only in correspondence with a terminal rotation phase of the door A close to said closed position.
  • the rotation of the door A comprises - from the point of view of the damper - two consecutive phases: a first phase in which the movement of the door A is not slowed down (as the damper 5 is deactivated, as it is not in contact with the intermediate element 4) and a second phase in which the movement of the door A is slowed down (as the damper 5 is activated, as it is in contact with the intermediate element 4 and compressed between this and the base 2).
  • damper 5 to the advantage of the overall compactness, is included in the encumbrance of the base 4, of which it - substantially - forms an integral part.
  • hinges 1 of the type described above must have compact and reduced dimensions, otherwise the pin could not be positioned outside the furniture.
  • the intermediate element 4 is advantageously provided with a first cam profile 41, formed in the area of the intermediate element which is facing (in an assembled condition) the damper 5, in particular on axis with its stem 51 on the side of the cylinder 52.
  • Said first cam profile 41 is positioned on the sleeve 45 of the intermediate element 4 which surrounds and defines the seat of the pin B of the rotation axis X and is therefore integral with the rotation with the intermediate element 4 itself.
  • the end 59 of the damper 5 facing and cooperating with the first cam profile 41 is correspondingly shaped, in order to facilitate the relative movement and sliding between the parts when they engage with each other.
  • the hinge 1 is provided with return and stable withholding means in a closed position of the door A.
  • the intermediate element 4 comprises a second cam profile 42 also positioned on the sleeve 45 of the intermediate element 4.
  • the first and second cam profile 41, 42 are preferably positioned at different angles with respect to each other, for the functionalities described hereunder.
  • the second cam profile 42 rotates integrally with the intermediate element 4 and has a different form with respect to the latter, as can be clearly understood hereunder.
  • the base 2 comprises two return and spring withholding elements 25, which protrude from the base 2 in the direction of the second cam profile 42.
  • Said return and spring withholding elements 25 cooperate with the second cam profile 42 to draw the door towards the closed position.
  • the return and spring withholding elements 25 are directed towards the cam profile 42 and, in a closed-door position, are engaged in a seat 44 of the latter in a closed-door position, as can be clearly seen in figures 9, 10 , so as to stably hold the door A in a closed position (or until a contrary force is applied, sufficient for overcoming the force of the springs), and, at the same time, act with a contrary force with respect to that of the damper 5, in order to assist the user in the last phase of the final portion of the closing run of the door A.
  • the intermediate element 4 and the wing 3 are in a single piece.
  • the intermediate element 4 can be coupled removably from the wing 3 and contains an adaptor 7 suitable for being inserted inside a seat 8, incorporated in the wing 3, by means of a straight sliding movement.
  • the adaptor 7 can therefore be blocked in the seat 8 by the reciprocal engagement of a tooth 71 provided on said adaptor 7 with a recess 83 and an abutment 84, provided on a lid 81 hinged on the wing 3.
  • the lid 81 can be tilted from a closed position in which it blocks the adaptor 7 in the seat 8 to an open position in which it releases the adaptor 7 from the same seat 8; the rotation axis of the lid 7 is preferably parallel to the axis X of the hinge 1.
  • the hinge 1 of the type described above can therefore, inter alia, be easily assembled; further advantages of this feature are described in the above-mentioned patent application MI2002A000297 in the name of the same Applicant, to which reference should be made for more detailed information.
  • the base 2 also comprises a first and a second plate-like extension parallel to each other, one of which is provided with coupling holes (with an axis perpendicular to the plate) with the wall P of the furniture, whereas the other ends with a slot in which the pin B of the axis X is housed and is connected by this to the intermediate element 4.
  • the intermediate element 4 has an overall "L" form with two substantially perpendicular plate-like extensions - one of which is provided with the sleeve 45 equipped with the cams 41 and 42 and cooperating with the slot of the base 2 thanks to the pin B - and the other provided with the above-mentioned adapter 7.
  • the adaptor 7 would be substituted by a fixed connection between the two parts.
  • the hinge 10 has the same parts describe above for the hinge 1 with the same functionalities and indicated with the same reference numbers, to which no further reference will be made for the sake of brevity, except for the fact that the hinge 10 differs from the hinge 1 with respect to the position of the damper 50.
  • This damper 50 preferably of the same type as the damper 5 described above, although in fact always positioned on the base 2, is incorporated in the same and its stem 52 extends towards the intermediate element 4.
  • the stem 52 (which is shown herein provided with a protection cap), does not come into contact with the intermediate element 4 except in a terminal phase of the closing run of the door A ( figure 22 ), as it is distant from the intermediate element in the first phase of the closing run ( figure 21 ).
  • the hinge 10 is provided with return and stable withholding means in a closed position of the door A, which comprise a second cam profile 42 positioned on the sleeve 45 of the intermediate element 4 itself; the second cam profile 42 therefore rotates integrally with the intermediate element 4.
  • the base 2 comprises a return and spring withholding element 250, which protrudes from the base 2 in the direction of the second cam profile 42.
  • the return and spring withholding element 250 (of which in this embodiment there is only one, but there can generally be one or more) is directed towards the cam profile 42 and cooperates with this to effect a return action in a closed position of the door.
  • the return and spring withholding element 250 in a closed-door condition, is engaged in a seat 44 of the latter, as can be clearly seen in figure 23 , so as to stably withhold the door A in a closed position (or until a contrary force is applied, sufficient for overcoming the force of the springs), and, at the same time, act with a contrary force with respect to that of the damper 50, in order to assist the user in the last phase of the final portion of the closing run of the door A.
  • the method of the invention comprises the following steps:
  • the method also comprises the step of activating return and stable withholding means in a closed position of the door A in a non-activated condition of the damper.
