Disclosed is a self-closing device for a drawer or for a moveable part of a piece of furniture that includes a support body for a slider moveable within a guide between a rear and a front position and vice versa by the action of a first elastic element. The slider is actuated by a drawing element integral with an extractable part affixed to the drawer or the like, the guide, at the area corresponding to the rear position of the slider, includes an element for moving the slider, suitable for engaging with an element for guiding the slider during its engagement with a drawing part present on the drawing element. There is further provided a stop element against which the slider lies directly or indirectly before engaging with a first guide element.

1. A self-closing device for a moveable part of a piece of furniture comprising: a slider adapted to be affixed to a fixed part of the piece of furniture, a support body for the slider, said slider moveable back and forth within a guide between a rear position and a front position by action of a fir
1. A self-closing device for a moveable part of a piece of furniture comprising: a slider adapted to be affixed to a fixed part of the piece of furniture, a support body for the slider, said slider moveable back and forth within a guide between a rear position and a front position by action of a first elastic device, said slider adapted to being actuated by a drawing element integral with an extractable part associated with a moveable part of the piece of furniture, said guide, at a zone corresponding to said rear position of said slider, comprises a first movement device for moving said slider, suitable for engaging with a first guide device for guiding said slider during its engagement with a drawing device present on said drawing element;a stop element against which said slider lies directly or indirectly before engaging with said first guide device in said first movement device of said guide,wherein said first movement device and said first guide device of said slider allow releasing the engagement of said slider with said drawing element when said slider is stressed so as to compress said stop element. 2. The self-closing device according to claim 1, wherein said stop element is mechanical and comprises a step of said support body against which said slider lies with a wall of said slider. 3. The self-closing device according to claim 2, wherein said slider has a surface inclined with respect to said wall against which said drawing device provided on said drawing element lies. 4. The self-closing device according to claim 1, wherein said stop element is elastically yielding. 5. The self-closing device according to claim 1, wherein said drawing device comprises a first pin and a second pin spaced from each other and adapted to be alternatively engaged with said slider. 6. The self-closing device according to claim 5, wherein said first pin and said second pin have different lengths. 7. The self-closing device according to claim 5, wherein said first guide device further comprises a third pin and a fourth pin engaged in said intermediate lateral cavity and said rear curve of said guide. 8. The self-closing device according to claim 5, wherein said slider comprises a tooth, and wherein said first pin and said second pin of said drawing element are alternatively engaged. 9. The self-closing device according to claim 5, wherein said slider comprises a projection by which it is engaged with said second pin, said projection having a cam-shaped lateral surface. 10. The self-closing device according to claim 1, wherein said guide has a groove and said first movement device comprises an intermediate lateral cavity and a rear curve of said guide. 11. The self-closing device according to claim 10, wherein said guide further has a front curve arranged, with respect to its axis, on the same side where said first movement device is present. 12. The self-closing device according to claim 10, wherein said first elastic device has a first spring, wherein said drawing device comprises a first pin and a second pin spaced a distance from each other and adapted to be alternatively engaged with said slider, and wherein interaction between at least said slider with said drawing element, at least said first spring, said intermediate lateral cavity and said rear curve leave the drawer or the moveable part of the piece of furniture free to slide in proximity to its closed position by a small extraction portion whose length is substantially equal to the distance of said first and said second pin. 13. The self-closing device according to claim 1, wherein said first elastic device has a first spring. 14. The self-closing device according to claim 13, wherein said stop element that is elastically yielding has a second spring, said first spring exerting on the slider at contact with said stop element a weaker elastic force than that of said second spring. 15. The self-closing device according to claim 13, further comprising a translation device for moving said moveable part of the piece of furniture along a small extraction portion with a force weaker than a force of said first spring. 16. The self-closing device according to claim 15, wherein said translation device comprises an ejector suitable for interacting with a stop element integral with said extractable part. 17. The self-closing device according to claim 15, wherein said translation device comprises at least one tilted guide along which said guide slides due to gravity. 18. A method for operating the self-closing device according to claim 1, wherein in a first step said slider is at a first idle position and holds with a tooth of a first pin of said drawing element, a second return step wherein said slider is drawn back by an external thrust exerted on said first pin of said drawing element in a second position, wherein a third pin and a fourth pin are engaged in an intermediate lateral cavity and in a rear curve of said guide concurrently releasing said first pin from said tooth and leaving said drawer free to move along a small extraction portion until a second pin engages with a projection of said slider, said projection through a cam moving said slider once back within said guide, a third extraction step wherein said slider is drawn into said guide in contrast to a first spring until said third pin engages into a front curve of said guide moving said slider into a third position wherein said first pin is released from said tooth leaving said drawer free, a fourth closing step wherein said drawing element extends beyond said slider with said second shorter pin, while said first pin engages with said projection releasing said third pin from said front curve and engaging said first pin with said tooth so that said slider returns to said first position due to the action of said first spring, moving said drawer to closed position.
