Hinged door leaves for wardrobes, walk-in closets and pieces of furniture in general, provided with magnetic damping and return devices

Abstract

A device for moving folding door leaves that open completely and are adapted for wardrobes or pieces of furniture in general include a single door leaf or one pair of door leaves hinged to each other, configured to be rotated from a completely closed configuration to a completely open configuration. The door leaves include a guiding device, the action of which is damped during the opening and closing movement by magnetic devices and damping systems that counteract their attraction force.

(5) FIGS. 11, 12, 13, 14, 15 show a detail of the solution with one door leaf (A) with guiding device (D1) in six different positions, from the closed position, shown in FIG. 11, to the completely open position, shown in FIG. 15.

(6) FIG. 16, instead, shows a top view of the wardrobe with magnetic damping and return device on the door leaf.

(7) Figures from 1 to 6 show, by way of non-limiting example, a wardrobe, walk-in closet, piece of furniture in general comprising at least two folding door leaves opening completely, with magnetic damping and return device and guide (D) for said first door leaf (A) and said second door leaf (B).

(8) Said first door leaf (A) is hinged to the fixed structure (F) of the wardrobe (M). In the example of FIGS. 1-6, said first door leaf (A) is hinged to a vertical door leaf (F) fixed in any way to the wardrobe (M), while the second door leaf (B) is hinged to said first door leaf (A).

(9) Said door leaves (A, B) rotate in order to pass from the closed configuration of the compartment (V) defined in the wardrobe, schematically shown in FIG. 1, to the completely open configuration of the compartment (V), schematically shown in FIG. 6.

(10) In said specific closed configuration, said door leaves (A, B) are substantially aligned with each other in such a way as to form a plane and are also aligned with the fixed structure of the wardrobe (M), in such a way as to perfectly close the compartment (V) defined in the wardrobe.

(11) In the completely open configuration, said door leaves (A, B) are folded, that is, they face each other and are parallel to each other.

(12) Said first door leaf (A) is hinged to said fixed door leaf (F) of the wardrobe (M), preferably through hinges of the concealed type, which are suited to allow a complete 180° rotation and mounted in apposite seats created between the adjacent upper edges of said first door leaf (A) and said fixed door leaf (F).

(13) Said wardrobe (M) is also provided with guiding devices comprising at least one first magnetic damping and return rod (D1), hinged between the external side of the top (C) of the wardrobe (M) and the upper edge of said first door leaf (A), and at least one second guiding rod (D2) hinged between the external side of the top (C) of the wardrobe (M) and the upper edge of said second door leaf (B), said rods being suited to guide the rotation movement of the door leaves (A, B) between said closed and open configurations.

(14) Said first rod (D1) can be directly or indirectly hinged to a bracket or spacer (S1), in turn fixed to said external side of the top (C) of the wardrobe (M) and suited to maintain said rod (D1) raised and to make it rotate on a plane which is parallel and close to the top (C) of the wardrobe (M).

(15) Said second rod (D2) can be directly or indirectly hinged to a bracket or spacer (S2), in turn fixed to said external side of the top (C) of the wardrobe (M) and suited to maintain said rod (D2) raised and to make it rotate on a plane that is parallel and close to the top (C) of the wardrobe (M).

(16) Said brackets or spacers (S1, S2) are fixed to said top (C) of the wardrobe (M) in a specific position according to the two open and closed configurations of the door leaves (A, B).

(17) The ends of the rods (D1, D2) are fixed to the upper edges of said first door leaf (A) and second door leaf (B) preferably through plates (S3) provided with holes (O1, O2) for the insertion of fixing screws, positioned on the upper edge of said first door leaf (A) and second door leaf (B), and wherein said holes (O1, O2) are preferably slot-shaped in order to allow the adjustment of the position of the rotation point of the end of the rod (D1, D2) with respect to the upper edge of said first door leaf (A) and second door leaf (B), thus making it possible to adjust the position of the point of rotation of the rods (D1, D2).

(18) More specifically, in order to correctly align the two door leaves (A, B) it is sufficient to translate one or both of said plates (S3) on the free edge of the door leaves (A, B).

(19) Said first rod (D1) comprises two half rods (D11, D12) (FIG. 7) which slide with respect to each other thanks to the presence of guides (G1, G2), in such a way as to allow the end hinged to the door leaf (A) to be moved near to and away from its point of constraint on the top of the wardrobe (M).

(20) According to the invention, said first rod (D1) is hinged to said top (C) of the wardrobe (M) through a bushing or a locking or coupling device (S1).

(21) The first half rod (D11) comprises cylindrical hollow bodies (G4) which are integral with the half rod (D11) itself, while said second half rod (D12) comprises pins (P1), the inside of which is provided with magnetic bodies, and wherein said pins (P1) are suited to slide in the holes of said cylindrical hollow bodies (G4) of said first half rod (D11).

(22) Said first rod (D1) comprising said two half rods (D11, D12) is also provided with shock absorbing elements or braking and damping devices which are combined with a magnetic return device, are integral with the rod (D1) itself and are suited to facilitate the return of the first door leaf (A) and to brake it in its closing and opening movement, and wherein said first rod (D1) is hinged to said bushing or coupling device (S1).

(23) Therefore, said first rod (D1) serves the function of damping the movement of the door leaf (A) during opening and closing and at the same time of facilitating the return of said door leaf (A), holding it in the open and closed configurations.

(24) The action of moving the ends of said first rod close to each other will thus be facilitated and they will be held in their final position by said magnetic elements which, in the completely retracted position of the half rods, keep said two ends of the rod with variable length (D1) near each other, thus closing the door leaves (A, B) in a stable manner and keeping them aligned with the fixed part of the wardrobe, and also keeping them folded in a compact manner in the completely open configuration.

(25) Both in the totally closed configuration of the piece of furniture, with said two door leaves (A, B) aligned with each other, and in the totally open configuration, in which the two open door leaves are superimposed, said pins (P1) will be at least partially introduced in said hollow cylinders (G4), exerting a constant attraction force during the opening and/or closing movements thanks to the presence of the magnets and thus keeping said door leaves (A, B) in a stable position.

(26) According to the invention, elastic or pneumatic elements (CP1) can be provided, which are placed inside the hollow cylinders (CC1) and are compressed due to the attraction force exerted by the magnetic elements (P1) with the purpose of damping the force exerted by said pins (P1) when accompanying said door leaves (A, B), during the opening and/or closing movement, with a constant and soft movement.

(27) Said damping elements (CP1), always placed inside the hollow cylinders (CC1), during the closing movement are compressed by the action of the magnetic elements (P1).

(28) The above can be applied also in the case of a wardrobe provided with a single door leaf suited to rotate by 180°. In this case, the device will thus comprise said first rod (D1) with variable length, in any way provided with the already mentioned adjusting and moving devices.

(29) Therefore, with reference to the above description and the attached drawings, the following claims are expressed.
