Hinge device for appliances with top loading

Abstract

A hinge device for appliances with top loading has a first fixing means (3) assigned to be fixed to a body (S) or framework of an appliance and pivotally connected, by means of a hinge pin (4), to a second fixing means (5) assigned to be fixed to a top door (P) or hatch of the appliance to allow the opening and closing strokes between extreme opening and closing conditions of said door. In an operative condition, the rotation axis of said hinge pin (4) and the plane of the door in the closed condition are horizontal or almost horizontal. The second fixing means (5) is provided with a first connection pin (6) parallel to and spaced from the hinge pin (4),said first connection pin (6) is connected to an end of a transmission means (9) whose opposite end has a second connection pin (10) parallel to the first connection pin (6) and which can slide in a second slot means (35) of a shaped guide means (19) of the first fixing means (3) and nearly rectilinear and parallel to the path portion (21).Such second connection pin (10) is connected to a shaped body means (13) comprising at least a roll means (14) and a coupling means (16) for and end of a resilient means (17) acting at least in adirection according to the opening direction. Said shaped guide means (19) has a path portion (21) delimited between a first extremity (22) and a second extremity (23) thereof (21) and having at leasta recess means (24) placed between said extremities (22, 23) where the roll means (14) abuts with said path portion (21) and moves along it in the opening stroke starting from the closed condition, in which the roll means (14) abuts the first extremity (22). The roll means(14) reaches at least a metastable opening condition where it (14) is in the at least one recess means (24) and it (14) abutswith one edge of said recess means (24) facing the second extremity (23) until, due to a thrust towards the opening direction sufficient to leave the recess means (24), the roll means(14) reaches thecondition of extreme opening in which it (14) abuts against the second extremity (23) and vice versa in the closing stroke.

Description

technical field [0001] This application relates to the field of household appliances and furniture, and relates to hinge devices for top loading or top entry appliances, especially for household appliances such as clothes dryers, washing machines, box refrigerators and the like which are equipped with horizontal pivots The door and the door is configured horizontally to close the case. [0002] With respect to the situation from closed to fully open of the hinge device, the hinge device is configured to allow the door to rotate or swing open and close, respectively, and vice versa, so that the rotation from closed to fully open is preferably within Between 86°-90°, but can be smaller or larger. Background technique [0003] The word "stroke" mentioned hereafter in this document, such as opening swing and closing swing, refers to the rotation or movement of the parts of the hinge device around the rotating needle of the device, or refers to the door fixed to the part. Or th...

Problems solved by technology

[0005] Disadvantages of such known hinge devices include that they do not allow the door to be in a half-open position, they are only stable when the door is fully open or closed

[0006] Another disadvantage of said known devices consists in the fact that they allow considerable weight to counterbalance the weight of the door, so that although only a little force is required to open the door, since the movable part of the device is fixed to the door of the device, the The action of opening the door will finally hit the opening position of the device to limit the lock or the action of opening will end up in a high-speed emergency stop and cause collisions, which will damage the device and the corresponding equipment, or such devices will ensure that the opening action has a low tail speed. It does take a lot of effort at first to open it.

[0007] Other disadvantages of some known devices include excessive complexity, high cost and / or not robust and reliable
