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...

An improved device (2, 2') for automatic closing of a door, to be applied to a hidden hinge (4) comprising two bodies (8, 1 0) which are articulated with each other by means of at least one pair of arms (48, 60) and are constrainable to a leaf (5) and to a fixed structure (6), respectively, said device (2, 2') being intended to be constrained to one (8) of said two bodies of said hinge (4) and tobe inserted, together with said body, into a corresponding cavity (7) obtained in said leaf (5), said device (2, 2') being characterized in that it comprises: _ a translating element (34) which can beengaged with an articulation arm (48) of said hinge (4), _ elastic means (42) interposed between a first element (44) associated with said translating element (34) and a second element (47) associated with said body (8) of hinge (4) to which said device (2, 2') is intended to be constrained, said elastic means (42) being configured to be loaded during the opening rotation of said leaf (5) associated with said hinge (4) and to return the mechanical energy stored in said opening step to said translating element (34) in order to cause the automatic closing of said leaf (5) associated with said hinge (4), _ means (50, 51, 52, 53, 55, 57) for varying the preloading of said elastic means (42), and therefore the automatic closing speed of said leaf (5), said means (50, 51, 52, 53, 55, 57) beingconfigured to modify the distance between said first (44) and said second (47) elements between which said elastic means (42) are interposed, and in that said means (50, 51, 52, 53, 55, 57) for varying the preloading of said elastic means (42) can be controlled from a base (75) of said body (8) of hinge (4) which is visible also once said closing device (2, 2') has been inserted into said cavity (7) obtained in said leaf (5).
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...
