• HINGE PROVIDED WITH AN AUTOMATIC OPENING AND CLOSING DEVICE FOR A FURNITURE PIECE DOOR
• the present invention relates to a hinge provided with an automatic opening and closing device for a furniture piece door, particularly, but not exclusively, a hinge of the push self-closing type, i.e. one which enables the door to be both opened and subsequently closed in an automatic manner.
• opening means which, following a push on the closed door by the user, generate a movement of the door in the opening direction by a first distance that is sufficient in order for the user to grasp it and open it completely, is well known.
• an opening device comprising an expulsion member for the door, which member is subjected to an elastic force, and means for retaining the expulsion member itself, which can generally be released by the user by pressing on the closed door to impose a backward movement of a few millimetres.
• the opening device must then be reloaded, for example by means of a push exerted by the user in the opposite direction on the door in the final part of the closing movement thereof, or by special reloading means actuated by the movement of the door itself.
• the technical task that the present invention has set itself, therefore, is to realize a hinge provided with an automatic opening and closing device for a furniture piece door which allows the aforementioned technical drawback of the prior art to be overcome.
• one object of the invention is to provide a hinge provided with an automatic opening and closing device for a furniture piece door which enables the expulsion member to be released even in the presence of movements of the door on the order of a few tenths of a millimetre.
• Another object of the invention is to provide a hinge provided with an automatic opening and closing device for a furniture piece door which can function in a lasting manner without any deterioration in performance and which can be applied to the furniture piece without requiring any particular processes or operations.
• the technical task according to the present invention is achieved by realizing a hinge provided with an automatic opening and closing device for a furniture piece door, said opening device comprising an expulsion member movable in opposition and under the action of first elastic means which subject it to a force in the opening direction of the door, and releasable retaining means for the expulsion member comprising a hooking element for the expulsion member, movable between a position of engagement and a position of disengagement with the expulsion member, said hooking element being held in the engagement position by the push exerted by the expulsion member via said first elastic means, characterized in that it comprises second elastic means for actuating the hooking element configured and disposed in such a way as to move the hooking element toward the disengagement position as a result of pressure exerted on the expulsion member in the direction opposite to the opening direction of the door.
• figure 1 shows a median longitudinal cross section of the hinge in the closing configuration of the door
• figure 2 shows a side view of the hinge of figure 1 in a configuration assumed during the push exerted by the user on the closed door;
• figure 3 shows a partial cross section of the hinge in the configuration illustrated in figure 2;
• figure 4 shows a side view of the hinge of figure 1 in a configuration assumed after the push exerted by the user on the closed door, at the moment of release of the expulsion member;
• figure 5 shows a partial cross section of the hinge in the configuration illustrated in figure 4;
• figure 6 shows a side view of the hinge of figure 1 in a configuration assumed at the end of the extraction of the expulsion member
• figure 7 shows a partial cross section of the hinge in the configuration illustrated in figure 6;
• figure 8 shows a side view of the hinge of figure 1 in a configuration in cui the expulsion member has been reset, and an enlargement of a detail thereof;
• figure 9 shows a partial cross section of the hinge in the configuration illustrated in figure 8.
• a hinge 2 provided with an automatic opening and closing device for a furniture piece door.
• the hinge 2 has a hinge box 3 applied to the door 1, a hinge arm 4 applied to a base 5 for fastening to a fixed part of the furniture piece, in particular to a shoulder
• rocker arms 7 and 8 which operatively connect the hinge box 3 to the hinge arm 4.
• the hinge 2 in a known manner, comprises pins 10, 1 1 articulating with the rocker arms 7 and 8 with the hinge arm 4, pins 12 and 13 articulating with the rocker arms
• the opening device comprises an expulsion member 17 movable in opposition and under the action of first elastic means 18, which subject it to a force in the opening direction of the door 1, and releasable retaining means for the expulsion member 17.
• the retaining means comprise a hooking element 19 for the expulsion member 17.
• the hooking element 19 is movable between a position of engagement and a position of disengagement with the expulsion member 17.
• the hooking element 19 is held in the engagement position by the push exerted by the expulsion member 17 via the first elastic means 18.
• the retaining means further comprise second elastic means 20 configured and disposed in such a way as to move the hooking element 19 toward the disengagement position as a result of pressure exerted on the expulsion member 17 in the direction opposite to the opening direction of the door 1.
• the opening device has a base body 21 applied to the hinge arm 4 and translatably supporting the expulsion member 17.
• the base body 21 supports a lever 23 pivotable in opposition and under the action of the second elastic means 20.
• the hooking element 19 is fashioned at one end of a first arm 22 of the lever 23.
• the first arm 22 of the lever 23 extends beyond the rear end of the base body 21 , where the hooking element 19 is engageable with a catch 24 present on the rear end of the expulsion member 17.
• the lever 23 has a pivot fulcrum 25 oriented orthogonally to the translation direction of the expulsion member 17.
• the second elastic means 20 comprise a torsion spring, interposed between the base body 21 and the lever 23, which in particular is wrapped around a pin constituting the pivot fulcrum 25 and has one end coupled to the first arm 22 of the lever 23 and one end positioned against a stop 26 present on the base body 21.
• the base body 21 has a box-like configuration for containing the expulsion member 17, whose rear end 26 extends out through a rear aperture 27 of the base body 21 and whose front end 28 extends out through a front aperture 29 of the base body 21.
• the base body 21 internally defines a housing 30 for the expulsion member 17 and the first elastic means 18, which in this case are represented by a helical spring deformable in the direction of movement of the expulsion member 17.
• the lever 23 extends adjacent to a side 31 of the base body 21 and has a first lever arm 22 of greater length and a second lever arm 32 of less length, which extends on the side opposite that of the first lever arm 22 relative to the pin 25.
• the base body 21 has an elongated hole 47 at the top for front adjustment of the fixing thereof to the hinge arm 4 by means of the screw 48.
• the hole 47 is elongated in the translation direction of the expulsion member 17, so that the fixing position of the base body 21 in the translation direction of the expulsion member 17 can be calibrated by loosening the screw 48 to modify the fastening position thereof in the hole 47 and subsequently re-tightening the screw
• the resetting device comprises a pivotable member 33 for the combined driving of the expulsion member 17 and lever 23.
• the driving member 33 is fulcrumed to the hinge arm 4 at 40 and has a drive cam 34 suitable for interfering with the wall of a recess 35 present on the expulsion member 17 so as to transform the pivoting of the driving member 33 into a backward translation of the expulsion member 17; the driving member 33 further has a pin 36 for driving a transmission rod 37 which at one end is fulcrumed to the pin 36 and at the opposite end has a pin 39 slidingly engaged in a slot 38 present on the second lever arm 32 so as to transform the pivoting of the driving member 33 into a pivoting of the lever 22 toward the engagement position of the hooking element 19.
• the pin 36 slidingly and freely extends through a curved slot 45 centred at 40 and fashioned on a side 31 of the box-like body 21.
• the driving member 33 can be directly or indirectly actuated by a mobile part of the hinge during the opening of the door 1.
• the driving member 33 can be actuated by a lever 8 * solidly joined to the rocker arm 8 by means of a transmission member 42 fulcrurned to the hinge arm 4 at 44.
• the pivot fulcrums 40 and 44 of the driving member 33 and the transmission member 42 are parallel to each other and to the pivot fulcrum of the lever 23 and in turn to the pivot fulcrums 10, 1 1, 12, and 13 of the rocker arms 7 and 8 which connect the hinge arm 4 to the hinge box 3.
• the hooking element 1 and/or preferably the catch 24 present on the expulsion member 17 is provided with a slanting surface 46 suitable for causing, when the hooking element 19 goes into the engagement position, an additional backward movement of the expulsion member 17 relative to the position reached under the action of the resetting device, in such a way as to increase the contact pressure of the hooking element 19 against the catch 24 determined by the first elastic means 18.
• the opening device is integrated into the hinge 2 in a position such that the front end of the expulsion member 17 can interfere with the edge 49 of the hinge box 3, which projects from the thickness of the door 1, or directly with the inside surface of the door 1.
• the door 1 is initially closed (figures 2 and 3) and the edge 49 of the hinge box 3 is resting against the front end of the expulsion member 17, which posteriorly restrains the hooking member 19 with the catch 24.
• the retaining force of the hooking member 19 in the engagement position is substantially determined by the pushing action that the first elastic means 18 exert on the expulsion member 17 in the extraction direction and in particular it is proportional to the degree of compression of the helical spring.
• the expulsion member 17 can freely snap forward due to the expansion of the first elastic means 18 and thereby give rise to the first opening phase of the door 1 (figures 6 and 7).
• the resetting of the opening device takes place during the subsequent phase of completion of the opening of the door 1 imposed by the user and is due to the rocker arm 8, which actuates the kinematic chain comprising the transmission member 42 and driving member 33 in cascade fashion.
• the rocker arm 8 pivots in a direction (anticlockwise in the figures) which determines the pivoting of the transmission member 42 in the opposite direction (clockwise in the figures) 42 and the pivoting of the driving member 33 in a concordant direction (anticlockwise in the figures).
• the driving member 33 by virtue of the pivoting thereof, performs a dual action: on the one hand, with the drive cam 34 it engages and pushes against the rear wall of the recess 35, generating a backward movement of the expulsion member 17, opposed by the first elastic means 18, which are compressed; on the other hand, with the pin 36, the driving member 33 actuates the transmission rod 37, which, with the pin 39, first slides in the slot 38 and finally pushes against the rear end of the slot 38, generating a pivoting movement of the lever 23 toward the engagement position of the hooking element 19, opposed by the second elastic means 20, which are compressed.
• the actuation of the lever 23 is thus time-delayed relative to that of the expulsion member 17, so that the lever 23 is made to pivot only after the catch 24 has passed over the hooking member 19 in its retraction movement.
• the rocker arm 8 reverses the pivoting direction and this simply causes the disengagement of the drive cam 34 from the rear wall of the recess 35 and the disengagement of the pin 39 from the rear end of the slot 38, while the opening device remains in the reset configuration since the hooking element 19 remains held in the engagement position thanks to the prevalence of the retaining action generated by the first elastic means 18 over the release action generated by the second elastic means 20.
• a particularly advantageous aspect of the invention consists in the fact that the automatic opening and closing device has a special configuration, thanks to which it can be integrated directly into the hinge, the retaining means being capable of achieving a correct release of the expulsion member even when the door pivots by a few tenths of a millimetre. This undoubtedly results in a simplification of the installation of the opening device, which does not require specific operations and improves the exploitability of the internal spaces of the furniture piece.
