Hinge device for refrigerators and furnishings

Abstract

An hinge device for refrigerators, other appliances and furnishings, in an operating condition of assembly to refrigerator or to other, comprises a first member (3) fixed to a refrigerator body and asecond member (5) fixed to a door of said refrigerator or obtained in such a door where said first member (3) and second member (5) are mutually connected by means of a hinge pivot (7) for the rotation of the door. The hinge pivot (7) is constrained to rotate in a first seat (9) obtained in a shelf means (11) fixed to the first member (3) and has at least one connection portion (13) with a polygonal section engaged in a complementary connection seat (15) of a connecting means (17) and in a complementary housing (18) of the second member (5) so as to prevent the mutual rotation between the hinge pivot (7), the second member (5) and the connecting means (17) which is rotatably connected to a first end of a connection rod means (21) whose second end is rotatably connected to a crank means (25) revolving around an own rotation pin (27) fixed to the first member (3). The crank means (25) has at least a first cam contour (29) onto which acts a roller (31) with an elastic force of a resilientmeans (33) having a first end connected to the first member (3) and a second end connected to said roller (31) by means of drive means (35). The first cam contour (29) is shaped to transmit to hingepivot (7) and to door a closing couple in an end closing condition and close to said closing condition.

Description

technical field [0001] The invention relates to the field of hinges, to a hinge device for furniture and appliances, in particular for refrigerators, with doors, windows or revolving doors around a vertical or horizontal hinge axis and capable of imparting spring force to such prefixed doors . Background technique [0002] Known hinges for vertical refrigerator doors generally each consist of a shelf fixed to the refrigerator frame or body and having a vertical axis hole for a vertical hinge pin engaging in a corresponding Has a vertical axis and is fixed into a cylindrical seat of a door or refrigerator door. [0003] A disadvantage of these known hinges is that they do not contribute in any way to the closing of the door, for example the door may remain ajar, with obvious consequences. [0004] Another disadvantage of these known hinges is that they do not limit or inhibit the closing and opening rotation of the door, mainly in the second case, posing a risk of damage to...
