A retaining device, particularly for a door of a household appliance

摘要

The device (1, 4) comprises a support structure (2) secured to the door (D) and in which a hook member (3) is mounted to oscillate, and a door locking device (4) secured in the domestic electrical appliance (A) facing an opening (5) provided in this appliance (A). The hook member (3) is mounted in the support structure (2) such that it may move in translation between a retracted position and a forward position, and may oscillate about a moving axis (12a, 12b). When the door (D) is closed the hook member (3) engages with the retaining formation (6a) of the appliance (A), oscillates about the axis (12a, 12b) against the action of a recall spring (13), leaving the rest position but remaining in the retracted position, and thus enters and passes through the opening (5), and then oscillates towards the rest position and engages with the retaining formation (6a) under the action of the recall spring (13). When the door (D) is urged to open while a locking slider (7) of the door locking device (4) is in the rest position, the hook member (3), initially retained by the retaining formation (6a), moves from the retracted position to the forward position, as a result of the relative displacement of the support structure (2), and oscillates about the axis (12a, 12b) against the action of the recall spring (13), becoming disengaged from the retaining formation (6a) and thus passing through and leaving the opening (5) of the appliance (A).
