Hinge for doors

Abstract

Door hinge, configured by a base body (3) having a flat surface (4), to be joined, by means of an adhesive or screws, to the upper and lower base of the piece of furniture, and a circular cavity (8) to receive, fitted therein, the lower or upper edge end (2a) of the door, either directly through insertion of a projection (9) of the door, dimensioned for that purpose, or through a rotation cylindrical part (11). The rotation cylindrical part (11) is an independent piece or it is joined integrally to the upper or lower edges end (2a) of the door (2) or it is part of the door itself. The edge of the base body (3) of the hinge (1) is provided with a recess (13) suitable for receiving, fitted therein, a projection (14) of the door in a matching position, intended to secure closing thereof.

(3) FIG. 2 shows an exploded isometric representation another example of the hinge object of the invention, in this case being provided for the direct attachment of the door at the base, without the rotation cylindrical part.

(4) FIG. 3 shows an exploded isometric representation of the hinge according to the invention, in this case in an example with the rotation cylindrical part fixed to the door.

(5) FIG. 3A shows an isometric view of the wall with cylindrical part (11) at the upper and lower ends.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(6) In view of the aforementioned figures, and according to the reference numbering chosen, it can be observed in them a non-limiting example of the door hinge, object of the invention, which comprises parts and elements indicated and described in further detail below.

(7) Thus, as it can be observed in said figures, the hinge (1), designed to couple both in the lower and in the upper section of the door (2) for which it is intended, is configured from a base body (3) featuring a flat surface (4), susceptible to be integrally joined, by means of an adhesive (5) or a screw (6) inserted in an orifice (7) provided therein for that purpose, to the upper and lower bases (15) and (16) of the piece of furniture (not shown) to which the door is coupled (2), and where the existence of a circular cavity (8) is contemplated, being said cavity suitable for receiving, fitted therein, the upper or lower edge end (2a) of the door.

(8) Obviously, as it can be observed in FIG. 1, the upper edge end (2a) of the door will be fitted in the cylindrical cavity (8) of the hinge (1) fixed to the upper base of the piece of furniture, and the lower edge (2a) of the door will be fitted in the cylindrical cavity (8) of the hinge (1) fixed to the lower base of the piece of furniture and the base bodies (3) of both hinges (1) will be fixed to the upper and lower section of the piece of furniture fastened to the previous edge thereof.

(9) In an example of an embodiment, shown in FIG. 2, said attachment of the upper/lower edge end (2a) of the door (2) in the circular cavity (8) is performed directly by inserting in said cavity a projection (9), determined by the existence of a stepped notched section (10) made respectively in said upper and lower end edges of the door, which is precisely dimensioned to fit in tightly in the circular cavity (8) and, upon rotation therein, to enable rotation of the door (2).

(10) Preferably, however, the attachment of the upper/lower edge end (2a) of the door (2) in the circular cavity (8) is carried out by means of a rotation cylindrical part (11) which is fastened inside of the cylindrical cavity (8) and improves sliding between both parts.

(11) In an embodiment example, the rotation cylindrical part (11), shown in FIG. 1, is an independent part which couples to the circular cavity (8) of the base body (3) of the hinge, so that it freely rotates therein, and it comprises a groove (12) that is accessible through its facing area, so that it is suitable to have the projection (9) of the upper and lower edges (2a) of the door (2) fitted therein and, thus, facilitate the rotation thereof.

(12) Alternatively, the rotation cylindrical part (11) is integrally joined, by means of any fastening system, for example bonded, to the lower and upper edges end (2a) of the door (2), as it is sown in FIG. 3.

(13) Finally, in another possible embodiment, there is a possibility contemplated for said cylindrical part (11) to be located in the upper and lower edges end (2a) of the door (2), being a part of the piece itself which makes up said door.

(14) Additionally, and in any of the embodiments described, the circular cavity (8) features an interior step (8a) which prevents the circular part (11) to come out of the housing thereof, when it is mounted in the upper section of the piece of furniture.

(15) Furthermore, also additionally, there is a possibility contemplated of having a recess (13) provided in the edge of the base body (3) of the hinge (1), intended to receive a projection (14) provided in the door, which has been placed next to the edge (2a) thereof in a matching position when closing the door, acting as a retention system to secure closing thereof upon pressure-fitting said projection (14) in said recess (13).

(16) As it has been stated above, to allow assembling the door in the hinges (1) described, the door (2) is made of a material with a certain grade of flexibility, such as plastic, methacrylate or a similar material, and further featuring little thickness so as to bend it slightly and enable the coupling thereof to the upper and lower hinges.

(17) Having sufficiently described the nature of the present invention, as well as the way it should be put into practice, it is considered unnecessary to describe it any further for a person skilled in the art to understand the scope thereof and the advantages that can be derived from it, stating that under the essential content of the present invention, it can be put into practice following other embodiments differing in detail from that indicated as an example, and which will lie under the protection scope procured, provided it does not alter, change or modify the fundamental principle thereof.
