Definitions

  • the present invention relates to a single-pin hinge for doors and/or panels of furniture or furnishing items.
  • doors and/or panels are provided which must or can be moved between a closed position and an open position to give access to or close a compartment or part of the furniture.
  • hinges For this purpose, different types of hinges can be used, such as the older and more classic ones consisting of a pair of wings extending from an intermediate axis. One wing is connected to the furniture and the other wing to the door and the pin serves as an intermediate articulation element. For these hinges there are generally no adjustments except for the presence of fixing slots in the wings.
  • the general objective of the present invention is to provide a single-pin hinge for doors and/or panels of furniture and/or similar furnishing items that is capable of solving the above-mentioned drawbacks of the prior art in an extremely simple, economical and particularly functional manner.
  • a further objective of the present invention is to provide a single-pin hinge for doors and/or panels of furniture and/or similar furnishing items that has an easy and guaranteed closure in the presence of openings less than or equal to 90°.
  • Another objective of the present invention is to provide a single-pin hinge for doors and/or panels of furniture and/or similar furnishing items which can be adjustable despite its constructive simplicity.
  • Yet another objective of the present invention is to provide a single-pin hinge for doors and/or panels of furniture and/or similar furnishing items which can have openings even greater than 90° without generating any type of collision.
  • Figures 1 and 2 show completely schematic perspective views which illustrate the type of movement that can be effected with a hinge according to the present invention, showing it in the closed position and in the maximum opening position respectively;
  • Said figures 1 and 2 show how this type of single-pin hinge, indicated as a whole with 11, is arranged between a door 12 and a bottom 13 of a piece of furniture or similar furnishing item.
  • Figures 3 to 7 show a first embodiment of a hinge according to the present invention.
  • FIG. 4 in particular shows this hinge 11 in a plan view from above with the single-pin hinge according to the invention connected in a fixed part thereof within a recessed seat 14 of a bottom 13 of a piece of furniture and in one of its movable parts connected to a door 12, at least in one of its corners S.
  • the hinge 11 is represented with the door 12 in an initial closing phase. It is in this phase that it can be seen how the damping phase is initiated.
  • the recessed seat 14 is suitable for receiving a box-like element, produced in two parts 15, 16, which in turn at least partially receives a shaped arm 17 supporting a rotation pin 18.
  • the rotation pin 18 is the point around which the articulation of the hinge 11 is effected, or around which the door 12 is caused to rotate with respect to the bottom 13 of the furniture.
  • the box-like element has a lower housing part 15, or female part, and an upper covering part 16, or male part.
  • the lower part 15 of the box-like element there is at least a plate portion 19 of the supporting arm 17.
  • a shaped connecting rod 20 of which a first end carries a pin 21.
  • a second end of the shaped connecting rod 20 is rotatably connected to the door 12.
  • the shaped connecting rod 20 in fact houses in a hole 22 thereof, formed at this second end, a plug 23 which is housed in a hole 24 formed in a block 25 associated with an L-shaped joint 26 of the door 12.
  • This L-shaped joint 26 is associated with a horizontal portion and a vertical portion of the door 12 and is arranged in correspondence with the edge S of door 12.
  • the shaped connecting rod 20 is kept in the recessed seat 14 above the plate portion 19 by a further plate 27 in which a guiding slot 28 is formed.
  • the pin 21 is positioned in the guiding slot 28 and causes the movement of the shaped connecting rod 20.
  • a depth-adjustment block 29 and a horizontal- or side- adjustment block 30 are arranged in the recessed seat 14 next to and alongside the further plate 27 above the plate portion 19.
  • Hexagon socket screws 31 and 32 that can be positioned frontally in respective holes 33 and 34 on one side of the two parts 15 and 16 of the box-like element, when coupled, allow the above-mentioned adjustment actions of the two blocks 29 and 30.
  • this stop element includes a threaded pass-through hole 35 which extends from a lower side of the plate 27 facing the outside of the bottom as far as the guiding slot 28 ( figure 4 ).
  • a long grub screw or hexagon socket headless screw 36 is inserted in this threaded hole 35, which can be actuated in front of the bottom 13, which limits the translation of the pin 21 in the guiding slot 28.
  • a sliding cursor 136 can be provided in the seat, equipped with a return spring with the possibility of insertion and disengagement. Consequently, by limiting the run of the pin 21 inside the slot 28, the movement degree of the shaped connecting rod 20 and therefore of the opening of the door, or the rototranslation of the connecting rod 20, can be selected.
  • this shows the angle of inclination according to which the pass-through threaded hole 35 is formed for limiting the run in the plate 27 according to an axis x.
  • the threaded pass-through hole 35 is in fact arranged according to an angle ⁇ with respect to an edge 55 of the plate 27 facing outwardly.
  • This edge 55 of the plate 27 is parallel to an end side of the bottom 13 of the piece of furniture on which the door 12 is abutted so as to define a selected maximum opening for the door 12.
  • This takes place specifically due to the fact that the grub screw or hexagon socket headless screw 36 is arranged at least with one of its free ends protruding inside the guiding slot 28 so as to prevent the free sliding of the pin 21 as far as the run end.
  • Figures 5 and 6 show two selectable positions of the door in maximum opening. More specifically, from a position of figure 4 that can also be considered a position of the door just opened, the arrangement provided in the hinge of the invention allows two extremely precise and advantageous open-door positions to be obtained for the use of the furniture.
  • Figure 5 shows a position in which the door 12 is open to a maximum of 95° and this position is reached in the following way.
  • This limitation prevents the shaped connecting rod 20 from moving outwardly from the position contained in the bottom 13 of the furniture and consequently the door 12 from opening further.
  • Figure 6 shows what happens if the grub screw 36 remains contained in the threaded hole 35 of the plate 27. The free end does not protrude into the guiding slot 28 and therefore does not prevent the pin 21 from sliding in the same for its entire length.
  • the shaped connecting rod 20 can be brought outwards from its initial position (for example figure 4 ) contained in the bottom 13 of the furniture with the pin 21 constrained to it, which moves to the bottom of the guiding slot 28 ( figure 6 ).
  • the pin 21, completely covering the guiding slot 28, thus reaches the stop and fixes the maximum protrusion of the shaped connecting rod 20 and the maximum rotation of the door 12 which opens at an angle of 140-160°, preferably 150° from its initial position flanked to the outer edge of the bottom 13.
  • This can be defined as the standard opening position, in any case having the certainty that the door 12 has an opening limitation.
  • a hinge according to the present invention it is therefore possible with a hinge according to the present invention to select the maximum opening of the door/hinge in two positions, according to the use or the user's preferences. It is clear that more than one stop element can be envisaged, thus defining various differentiated openings of the door 12, if necessary and required.
  • the selection of the maximum opening of the door shown in the exemplary but non-limiting figures can be 95° or 150°, it can be selected by adjusting the above-mentioned grub screw 36 or other stop element according to its positioning.
  • the hinge of the present invention therefore allows at least a double opening position depending on the positioning of one or more run-stop elements arranged along the slot.
  • the stop elements shown in the form of a grub screw can however be a lever, a cam or other stop elements having various forms that block the sliding of the pin in the guiding slot 28.
  • a damping group is associated with said shaped connecting rod or lever 20 which prevents the door 12 from hitting the furniture, closing too rapidly on the same.
  • This damping group is obtained thanks to the presence of a cylinder 37, whose stem 38 is normally extended at rest, on one end of which a side portion of the shaped connecting rod 20 acts. More specifically, said cylinder 37 with its relative stem 38 is positioned inside a housing or cap 39 which contains and guides it. And both are arranged at one end of a horizontal side of the L-shaped joint 26 of the door 12.
  • the housing or cap 39 provides side slots 40 arranged on facing sides in which final parts of a shaft 41 are inserted, that slides within the same.
  • the shaft 41 in turn acts on the free end of the cylinder 37 and on moving, it can cause the compression of the stem 38, therefore slowing down the closing run of the door.
  • Figure 4 shows the position of the parts in an initial damping phase when closing the door on the piece of furniture.
  • the damping group according to the invention described therefore prevents the door/hinge from hitting the furniture and, as seen, is always present, but is only actuated before the door/hinge closes completely.
  • This damping unit according to the invention is in fact actuated by the contact of the long connecting rod 20 on the pin 41, or on the end of the cylinder 37.
  • the hinge 11 according to the invention has been seen to provide two adjustments, namely one in the frontal direction or depth and one in the side or horizontal direction.
  • the front adjustment is effected by adjustment of the screw 31 which acts on the front adjustment block 29.
  • the side adjustment is effected by means of the screw 32 which acts on the side adjustment block 30.
  • a third adjustment in a vertical direction is provided in this hinge 11 through a vertical adjustment group, as will be seen hereunder with particular reference to figure 7 .
  • the block 25 is provided in the L-shaped joint 26 of the door 12, a hole 42 being formed in said block, where a part of the rotation pin 18 is housed around which the door 12 is caused to rotate with respect to the bottom 13 of the furniture.
  • This rotation pin 18 in another portion thereof is arranged pivoted to the supporting arm 17, more specifically in a hole 43 of a right-angled extension 44 of the plate portion 19 of the supporting arm 17.
  • Said right-angled extension 44 of the plate portion 19 of the supporting arm 17 is such that it extends outside the box-like element 15, 16.
  • said right-angled extension 44 is arranged so as to be able to be positioned below the horizontal portion of the L-shaped joint 26 of the door 12, when the door 12 approaches the bottom 13 of the furniture for closure.
  • the block 25 is housed in a vertical portion of the L-shaped joint 26 of the door 12 in correspondence with the joining of the two sides of said joint in a housing 45.
  • the block 25 has a horizontal threaded hole 46 which receives an adjusting screw 47.
  • a free end of this adjusting screw 47 acts in contact on an adjustment cam 48 oscillating around a pin 49 inserted in a hole 50 of the block 25.
  • the vertical adjustment is carried out by acting on the adjusting screw 47 which, in contact with the adjustment cam 48, forces the latter to rotate.
  • the adjustment cam 48 rotating on the pin 49 comes into contact with an upper end 51 of the rotation pin 18.
  • This rotation causes a downward thrust which causes the vertical translation of the block 25 and therefore of the whole door that is associated with the L-shaped joint 26.
  • this adjustment group or rather the block 25, is firmly fixed to the L-shaped joint 26 by means of a screw 52. Furthermore, the fixing is ensured by an interlocking present, as a seat on the L-shaped joint 26 and as a key on block 25. This allows a rigid junction of the two parts, thus avoiding a possible misalignment on the rotation pin 18.
  • the part of the hinge 11 positioned in the recessed seat 14 of the bottom 13 of a piece of furniture is contained, as already mentioned, in the box-like element, produced in two parts 15, 16, which is kept closed by means of a pair of screws 54.
  • FIGS 8 to 12 show a second embodiment of a hinge according to the present invention in which identical elements are indicated with the same reference numbers used for the embodiment shown in figures 3 to 7 .
  • a spring 56 which causes the forced closing of the door with respect to the bottom 13 of a piece of furniture or similar furnishing item, when the door is open and has an opening equal to or less than 90°.
  • This spring 56 is actuated in the example shown, directly by the shaped connecting rod 20, or by the pin 21, as can be seen from the attached figures.
  • a slide 57 above the plate 27 is provided.
  • This slide 57 slides inside a guiding channel 58 formed in the body of the depth-adjustment block 29.
  • the slide 57 is U-shaped in the form of a profiled section, as is also the guiding channel 58 which is complementary to it in shape.
  • a first eyelet end 59 of the spring 56 is attached to a first pin 60 which extends inside the slide 57.
  • a second opposite end 61 of the spring 56 also in the form of an eyelet, is hooked to a second pin 62 which extends from plate 27.
  • the slide 57 moreover, almost in correspondence with one of its ends facing the second pin 62, extends below into a tooth 63, protruding towards the inside of the plate 27 and sliding both with respect to the plate 27 and to the body of the depth-adjustment block 29 within respective recesses (not shown).
  • Figure 9 shows how, in the closed hinge position, with the door close to the bottom 13 of the furniture, the pin 21 arranged in the slot 28 is still detached from the tooth 63. In this way the slide 57 is in the rest position and the spring 56 is at minimum load as previously determined.
  • the pin 21 then slides into the slot 28 and the spring 56 only produces a certain resistance to opening up to 45°, which is however allowed.
  • the pin 21 then tends to move from the position shown in figure 10 to the run end in the slot 28 as shown in figure 11 when the door is opened up to about 150°.
  • the hinge of the present invention in addition to possible adjustments according to a front and side direction, also allows the hinge to be adjusted in a vertical direction, improving and increasing its possible applications.
