Definitions

  • the present invention refers to a device for snap coupling and releasing a movable part to/from a fixed part of a furniture piece, and in particular it refers to a ratchet device.
  • Known ratchet devices permit coupling and releasing the movable part, such as a shutter or drawer, to/from the fixed part, by accumulating mechanical energy during the coupling step which is returned during the releasing step in order to facilitate the opening of the movable part .
  • a magnetic ratchet device which is adapted to interact with a ferromagnetic plate attached to the movable part .
  • Such device has several drawbacks, including the fact that the magnetic coupling force can be insufficient when the movable part is very heavy, and the fact that after many opening and closing operations of the movable part, the magnetic plate can be detached from the movable part to which it is glued. Recently, there has been a widespread tendency to employ one such magnetic ratchet device in combination with hinges, which in closed shutter position exert a thrust on the shutter towards its open position. Such push-opening system however opposes the magnetic coupling force, penalising the performances of the magnetic ratchet.
  • the technical task which the present invention proposes is therefore that of making a ratchet device for snap coupling and releasing a movable part to/from a fixed part of a furniture piece which permits eliminating the lamented technical drawbacks of the prior art .
  • one object of the invention is that of making a ratchet device for snap coupling and releasing a movable part to/from a fixed part of a furniture piece which is easy and quick to assembly, compact, secure and economical .
  • Another object of the invention is that of making a ratchet device for snap coupling and releasing a movable part to/from a fixed part of a furniture piece which can versatilely be used in different applications .
  • the device disclosed by the present invention offers a more secure seal, since the coupling is of mechanical type .
  • the device is capable of permitting the fine adjustment of the hinging system (for a shutter) or guide system (for a drawer) of the movable part with respect to the fixed part without losing effectiveness.
  • the coupling travel and the releasing travel are the same, such that the overall bulk of the device can be extremely limited.
  • the device has a high versatility of use, the tubular container being able to be inserted in an adapter or in a blind hole of the movable body or attached on a wall, on a shelf, on the top or on the base of the furniture piece.
  • the adapter permits the adjustment of the air present between the movable part and the fixed part of the furniture piece, and advantageously can be of the type already present for other devices .
  • the device has a snap assembly system of its tubular container which is extremely simple and quick. Moreover, the device of the present invention is well adapted for use in combination with a hinge with push-opening system.
  • Figure 1 shows an axial section of the snap coupling and releasing device mounted on a furniture piece by means of an adapter, in the position in which the head of the slider is released from the stop,-
  • Figure 2 shows the same section of figure 1 in the position in which the head of the slider is coupled to the stop
  • Figure 3 shows a perspective view of the coupling and releasing device in assembled position
  • Figure 4 shows a perspective view of the coupling and releasing device in exploded condition
  • Figure 5 shows a perspective view of an axial section of the central part of the tubular container
  • Figure 6 shows a perspective view of the stop.
  • a device 1 for coupling and releasing a movable part
  • the movable part 2 can be a slidable drawer or a shutter hinged to the fixed part 3.
  • the device 1 comprises a tubular container 4 in which a slider 5 is positioned, such slider 5 having a longitudinal axis 6 with respect to which it is rototranslatable.
  • the slider 5, outside the container 4, has a shaped head 7 which can be oriented into at least one first angular position around the longitudinal axis 6 for coupling the movable part 2 to the fixed part
  • the device 1 has a stop 8 having a shaped opening 9 in which the head 7 is adapted to be coupled when it assumes the first angular position, and from which the head 7 is adapted to be released when it assumes the second angular position.
  • the container 4 is attached to the fixed part 3, while the stop 8 is attached to the movable part 2.
  • the stop 8 has a cylindrical body with helical thread 10 on the side surface, so to be housed in its own impression 11 made in the movable part 2, with the possibility for adjusting the orientation of the shaped opening 9.
  • the screw connection type of the stop 8 in the impression 11 allows avoiding damaging the generally wood material constituting the movable part 2.
  • the opening 9 of the stop 8 is rectangular and the head 7 of the slider 5 is in the form of a hammer. In such case, there exists only one first angular coupling position and only one second angular releasing position of the head 7 from the opening 9 of the stop 8.
  • the opening of the stop 8 could have a star shape, in order to obtain multiple first angular coupling positions and multiple second angular releasing positions of the head 7 from the opening of the stop.
  • the width of the rectangular opening 9 is appropriately greater than the width of the hammer head 7, as is clearly visible in figure 1, in order to freely permit the fine adjustment of the hinging system (for a shutter) or guide system (for a drawer) of the movable part 2 with respect to the fixed part 3.
  • the tubular container 4 has an open end 12 through which the head 7 of the slider exits outward, a part 13 (tubular part open at one base thereof and closed at the other base thereof defining the bottom of the container 4) which is distal with respect to the open end 12, a part 14 (tubular part open at both bases, one of which defining an open end 12) which is proximal with respect to the open end 12 and a central part 15 (tubular open at both its bases) arranged between the distal part 13 and the proximal part 14.
  • the container 4 moreover has quick snap connection means between the distal part 13 and the central part 15, and between the central part 15 and the proximal part 14.
  • the quick connection means comprise at least one tooth 16 of the distal part 13 adapted to be inserted in a corresponding window 17 of the central part 15, and at least one tooth 18 of the central part 15 adapted to be inserted in a window 19 of the proximal part 14.
  • the elastic means comprise a helical spring 21, arranged coaxially with the slider 5.
  • the spring 21 at one end thereof supports the pusher 20, and at the other end thereof is supported by the bottom of the tubular container 4.
  • the pusher 20 has a head 22 equipped with a hemispherical protuberance 23 which ensures the punctiform contact with the round front surface 30 of the end 24 of the slider 5, in order to limit to a minimum the friction which is generated during the rotation of the slider 5 on the pusher 20 (in contact with the slider 5 through its protuberance 23) .
  • the pusher 20 and the spring 21 are entirely- contained in the central part 15 and in the distal part 13 of the container 4, while the slider 5 is predominantly contained in the proximal part 14, the slider 5 exiting outward from the opposite ends 12 and 29 of the proximal part 14.
  • the side surface of the end 24 of the slider 5 has a groove 26 in which a ring 27 is snap-associated, such ring 27 adapted to interfere with a shoulder 28 made inside the end 29 of the proximal part 14 in order to block the extraction of the slider 5 from the container 4 after the assembly of the latter.
  • the slider 5 has a cylindrical body, with spacers 31 extended along its generatrices, such spacers 31 adapted to limit the contact points with the inner side surface of the proximal part 14 in order to reduce to the minimum the friction generated when the slider 5 rotates.
  • the rotation means of the slider 5 are of known type already used for ball-point pens and thus are not described here in detail. In practice, they provide for, on the perimeter of the slider 5, a first pair of identical projections 32 diametrically aligned with each other and a second pair of identical projections 33 diametrically aligned with each other and placed at a different axial height of the slider 5 from the first pair of identical projections 32, from which they are angularly offset in a suitable manner with respect to the axis 6 of the slider 5 itself.
  • the rotations also provide for, on the inner perimeter of the proximal element 14, a series of four identical, angularly equispaced cam elements 34, interposed between the first pair of projections 32 and the second pair of projections 33, with which they are adapted to interact so to generate the axial rotation of the slider.
  • the device 1 is positioned in an adapter fixed to the fixed part 3, which also permits the adjustment of the air present between the movable part 2 and the fixed part 3 when the movable part 2 is coupled thereto.
  • the adapter has a box body 35 equipped with suitable means for housing the container 4, and the box body 35 bears an adjustment screw 36 positioned coaxially with the slider 5.
  • the end of the adjustment screw 36 has a snap connection tooth 37 into a hole 38 of the distal part 13 for the movement of the container 4 along the axial direction 6.
  • the container 4 is integral with the adjustment screw 36 in the latter' s only translational movement component, thus by actuating the adjustment screw 36, the container 4 is axially moved in the longitudinal direction with respect to the adapter .
  • the adapter is an accessory, it being conceivable for example to position the container 4 in a blind hole of the fixed part 3.
  • the container 4 is assembled in the following manner: the pusher 20 is inserted in the coils of the spring 21, which is inserted through the central part 15 so to be abutted against the bottom of the distal part 13; the slider 5 is inserted through the proximal part 14 and the ring 27 is attached to the end 24 of the slider 5, which exits from the end 29 of the proximal part 14; the distal part 13 is snap-joined to the central part 15, and the central part 15 is snap-joined to the proximal part 14.
  • the head 7 of the slider 5 is length-wise arranged parallel to the long sides of the rectangular opening 9, with which it does not interfere .
  • the movement of the slider 5 for coupling the movable part 2 to the fixed part 3 comprises a translational travel along the axis 6 which is formed overall by a first translational component in the direction of insertion in the container 4 and a second translational component in the direction of extraction 5 from the container 4.
  • Each translational component is associated with a rotation of 45° around the axis 6 at the same time as the translational travel, for an overall rotation of 90° .
  • the translational insertion component is activated by the thrust of the bottom of the opening 9 of the stop 8 against the hammer head 7 of the slider 5; the translational extraction component is activated by the extension of the spring 21, which is loaded by being compressed during the translational insertion component; while the rotational component is activated by the rotation means of the type used for ball-point pens, described above.
  • the translational extraction component creates a distance between the front facing surfaces of the movable part 2 and the fixed part 3, which allow the subsequent releasing movement.
  • the 90° rotation permits the hammer head 7 to be length-wise arranged transverse to the long sides of the rectangular opening 9, with which it interferes.
  • the double arrow 39 in figure 2 illustrates the size of the translational component of the slider 5, in the insertion and extraction direction.
  • the subsequent movement of the slider 5 for releasing the movable part 2 from the fixed part 3 is carried out with the same modes and comprises a translational travel and a simultaneous rotational travel of size equal to those of the preceding movement .
  • the materials used, as well as the sizes, can be of any type according to the needs and the state of the art.
