Patent ID: 7748800

Claim:
A device for automatic shock-absorbed closing of pull-out furniture elements, in combination with the pull-out elements, comprising: a support ( 2 ) provided with first brackets ( 2 a ) for stable anchoring to a fixed part of a cabinet and frontally ending with two parallel prongs ( 2 b ), said prongs ( 2 b ) having longitudinal slots ( 3 ) having an inverted U-shape, a hydraulic cylinder ( 1 ) containing an oil and having a front bottom proximal to said prongs ( 2 b ) and back bottom distal to said prongs ( 2 b ), said hydraulic cylinder ( 1 ) being supported by said support ( 2 ), a stem ( 70 ) having a front section ( 70 a ) coming out of the front bottom of the cylinder ( 1 ) and a back section ( 70 b ) coming out of the back bottom of the cylinder ( 1 ), an internal piston ( 8 ) connected to said stem ( 70 ) and slidably mounted inside said cylinder ( 1 ) defining a first chamber ( 1 b ) and a second chamber ( 1 a ), the internal piston ( 8 ) of the cylinder having a first series of spaces ( 9 ) for the passage of oil from the first chamber ( 1 b ) to the second chamber ( 1 a ) and an additional series of through holes ( 10 ), a small plate ( 11 ) constantly subjected to the action of a return spring ( 12 ) in order to close one side of said internal piston ( 8 ) and prevent the oil from seeping through the holes ( 10 ) of the piston during the retraction of the stem ( 70 ) that coincides with the closing travel of the pull-out element, a sliding pin ( 4 ) having a horizontal axis being disposed in the longitudinal slots ( 3 ) of the prongs and connecting a parallel pair of identical oscillating plates ( 5 ), the oscillating plates being connected to a pivoting pin ( 6 ) applied at an end of said front section ( 70 a ) of the stem ( 70 ) of the cylinder ( 1 ), an helical cylindrical spring ( 13 ) being disposed around said back section ( 70 b ) of the stem ( 7 ) of the piston ( 8 ), a second bracket (S) attached to the pull-out element having a deep hook-like notch (P) that receives the sliding pin ( 4 ) and cooperates with said pin.
