Embodiment Construction

[0033] As shown in the figures, the improved device 2, 2' for self-closing doors according to the invention will be associated with a hinge 4 for articulating the door leaf 5 relative to a fixed structure, for example relative to a jamb 6 of the door hinged and this device 2 , 2 ′ will be recessed relative to said fixed structure in a corresponding housing cavity 7 obtained in the hinged door leaf 5 .

[0034] Preferably, the hinge 4 is of the concealed type, since it is concealed when the door leaf 5 is closed. Furthermore, the hinge 4 is preferably of the type enabling a rotational movement of the door leaf 5 relative to the fixed structure 6 up to approximately 180°.

[0035] In particular, the hinge 4 comprises two hinge bodies 8 , 10 interconnected by a pair of rocker-shaped arms 48 , 60 , which enable the door leaf 5 to rotate relative to the jamb 6 .

[0036] The hinge body 8, 10 comprises: two flanged receptacles 14, 15, both cup-shaped, recessed in the thickness of t...

Abstract

The present application discloses an improved device (2, 2') for self-closing doors, which is to be applied to a concealed hinge (4) comprising two bodies (8, 10), which Hinged to each other by at least one pair of arms (48, 60) and constrained respectively to the door leaf (5) and the fixed structure (6), said means (2, 2') will be constrained to said hinge (4) on one (8) of said two bodies and inserted together with said bodies in a corresponding cavity (7) obtained in said door leaf (5), said means (2, 2') are characterized in that It comprises: - a translating element (34) able to engage with the articulating arm (48) of said hinge (4), - elastic means (42) placed between the first element (44) and the second between the elements (47), the first element being connected to the translation element (34), the second element being connected to the body (8) of the hinge (4), the means (2, 2') constraining On said body (8), said elastic means (42) are arranged to be loaded during the opening rotation of said door leaf (5) connected to said hinge (4) and will be stored during said opening step Mechanical energy returned to the translation element (34) in order to automatically close the door leaf (5) connected to the hinge (4) - for changing the preload of the elastic device (42) and thus changing the means (50, 51, 52, 53, 55, 57) for the automatic closing speed of the door leaf (5), said means (50, 51, 52, 53, 55, 57) being arranged to change the (44) and the distance between the second element (47), the elastic means (42) is inserted between the first element and the second element, wherein, for changing the elastic means ( 42) said means (50, 51, 52, 53, 55, 57) of preload can be controlled from the base (75) of said body (8) of hinge (4), once said closing means (2 , 2') has been inserted into said cavity (7) obtained in said door leaf (5), this base can also be seen.

Description

technical field [0001] The present invention relates to an improved device for automatically closing a door leaf, such as a closet or door, hinged by hinges to a fixed structure or jamb, such as a closet or door. Background technique [0002] Devices are known for automatically closing a door leaf provided with a movable external arm hinged on the door leaf itself. These devices are not entirely satisfactory as they are cumbersome and do not have a very pleasing appearance. [0003] Also known are recessed and concealed devices in the thickness of the door leaf, also known as concealed door closing devices. They are rather complicated to manufacture and install; moreover, once they are mounted on the leaf, the device is no longer adjustable, in particular the speed of automatic closing of the leaf, unless the device itself and the connection to it are removed from the leaf hinge. [0004] For example, in the door closing device of WO2015 / 145364, the adjusting device for t...
