The frame (4) has at least one lug (441) and advantageously two lugs (441, 442) arranged on the sides of a central, inverted V-shaped, projecting, and hollowed portion into which the key (52) is inserted during the opening and closing movement. The frame (4) has at least one flat surface and an oblong opening advantageously arranged in the center of the cylindrical shape, directly above said central hollowed portion.

[0031] Fig. 6 represents a 3D view of the key (52), also acting as a hinge pin or spindle or pivot of a hinge, of the unclipping device of an opening by rotation against a frame.

[0032] With reference to [Fig. 6], said key (52) comprises three zones or parts, typically along its main dimension, having three different purposes. The key (52) comprises, at one of its ends, at least one rim with an opening (521) (or cavity) intended to allow the connection of the return means (53), and then from this end, a flat leading to the S-shape (525) of which a flattened curve or ramp has at least one lug (522) and advantageously two lugs (522, 523) arranged on the sides of the edges of the key (52), and intended, during the closing movement, in particular to cooperate with the lugs (441, 442). Finally, the key (52) comprises at least one flat (524) slightly formed at its end opposite said rim; said plate is advantageously arranged and intended to cooperate with said central part hollowed out in the center of the cylindrical shape of the frame (4). How the device works

[0033] The operation of the maneuvering device or rope and its method of use will now be described.

[0034] Starting from a container, equipped with the invention as a hinge, when the user wishes to use this container to open it, he proceeds to open said container by lifting the opening (2) upwards.

[0035] Said opening (2) drives the insertion mechanism (5) integral with the opening (2). When the opening (2) or cover is rotated, the flattened curvature, or The ramp, connected to the key (52), and the lugs (522, 523) pass freely under the projecting V-shaped central portion and the lugs (441, 442) (or the ramp) of the frame (4) or the box. The flexible part of the closing means (54) deforms (reversibly) to allow the lugs (441, 442) of the frame (4) to pass through, in the case of a fully open position selected by the user.

[0036] By stopping its rotational movement before the deformation of the closing means (54), the user has the possibility of leaving the opening (2) in connection with the fixed part (3).

[0037] Starting from a container, equipped with the invention as a hinge, when the user wishes to use this container to close it, he proceeds to close said container by placing the opening (2) on the top of said rim of the frame by matching the flat (524) of the key with the housing provided at the level of said central part hollowed out in the center of the cylindrical shape of the frame (4).

[0038] Then, the user closes the opening (2) onto the fixed part (3) by translation and / or rotation on this hinge axis. Said opening (2) drives the insertion mechanism (5) which is integral with the opening (2). During the translation and / or rotation of the cover and therefore of the opening (2), the flattened curve, or ramp, linked to the key (52) as well as the lugs (522, 523) pass over the central V-shaped part protruding as well as the lugs (441, 442) (or the ramp) of the frame (4) or the box and pushes, in translation along the axis of the key (52), said key (52) so as to disengage the lugs (441, 442) to allow them to pass over the lugs (522, 523) of the key (52). At the end of the translation and / or rotation of the opening (2), the return means (53) brings back and holds the key (52) in its housing against said central part hollowed out in the center of the cylindrical shape of the frame (4) or pivot.

[0039] Thus the container (not shown) is closed with the opening (2) which now remains attached to the frame (3).
