Definitions

  • the present invention concerns a perfected invisible hidden door hinge.
  • hinges of this type comprise two connecting bodies, one on the jamb side and one on the door side, respectively insertable in the jamb or in the leaf of the door.
  • the two connecting bodies are connected to each other by an articulation device, generally composed of hinge arms structured in such a way to ensure the relative movement of the two connecting bodies (and, therefore, of the door with respect to the jamb). With the door closed, the hinge arms are received in a housing compartment formed in combination by the two connecting bodies which face one another, thus making the hinge invisible from both sides of the door.
  • a support structure of the connecting bodies is the intermediate means between the articulation device and the door or the jamb, in particular interacting with and/or supporting, in correspondence of two of its end portions, fixing means for fixing the hinge to the jamb or the door.
  • Said fixing means can be engaged directly to the support structure or acting between it and the jamb or the door by means of one or more intermediate elements.
  • the hinge provides a limited number of components: the connecting body is reduced substantially to the relevant support structure (apart from the fixing means and possible intermediate elements) and the hinge, therefore, substantially reduces to the two support structures connected to one another via the articulation device.
  • the hinge has a greater number of components, especially when one or more adjustments of position along one or more respective directions in space is realized in it.
  • one or both of the connecting bodies comprise, in addition to the support structure, one or more movable bodies and/or one or more movable inserts associated in various ways to the support structure (and by this directly or indirectly supported), each being movable with respect to the other and/or to the support structure for a respective adjustment position.
  • a generally nested structure in which the articulation device is engaged to each connecting body directly on the movable body or movable inserts which are most distal from the support structure.
  • the structure of support and movable bodies therein nested generally have a central cavity and, on opposite sides of the latter, flat flange portions for the engagement of fixing and/or adjusting means.
  • the movements of various movable bodies and/or movable inserts with respect to each other, and/or with respect to the support structure, are realized by means of respective adjusting means.
  • Even the articulation device can be more or less complex, depending on the elements that compose it and on their shapes.
  • each of the main components of the hinge (the support structures, the movable parts and/or movable inserts, the arms or arm elements that compose the articulation device) must have geometrically complex shapes and are characterized by numerous details, each of which must be made with precision to ensure the correct operation of the hinge.
  • a hinge provided with movable bodies and/or movable inserts presenting a certain complexity is a detail useful for a position adjustment.
  • a seat for inserting the head of an adjusting actuator which allows the rotation of the adjustment actuator about an axis and, at the same time, prevents its translation along the same axis.
  • This is generally a housing groove locally complementary to the shape of the actuator itself.
  • the injection molding using the of molten steel is a complex technology, which requires numerous processing steps and, since it does not ensure the accuracy of the various parts, it requires an injection molding by subsequent stages and/or mechanical machining performed on the workpiece subsequently to its formation by injection molding.
  • the use of non-negligible material thicknesses occurs, with the consequent use (and loss) of considerable amounts of material.
  • One or more metal sheets can be placed over one another to realize the support structure and the relevant movable bodies (in particular by nesting the "U” portions of the metal sheets one inside the other and leaning the remaining portions of the metal sheets that are located on opposite sides of said "U"-shape on one another).
  • the used metal sheets must have a very high thickness, thus making necessary the use of a large amount of material and making very difficult (because of the stiffness of the material to be machined) the production of the thus constructed hinge components.
  • the obtained hinges then, have an open structure which, in addition to being aesthetically unpleasant, can cause installation problems in the jamb or in the door leaf.
  • hinges are known wherein a plastic casing (generally obtained by molding) is added to the supporting structure, realized in the above manner, to the purpose of protection and aesthetic improvement. While partially solving the inconvenience, this solution requires the use of a further processing and a specially made component of a different material.
  • the arms that make up the articulation device have complex three-dimensional shapes that are also made by a metallic material injection molding, with all the problems described above.
  • one partially abandons the complexity of the shape of the arms, and realizes the same as packs of stacked metal flat sheets one is left however with the disadvantage of having to use a large amount of material in an aesthetically poorly appreciable configuration.
  • One object of the present invention is to obviate the above drawbacks, by providing an invisible hidden hinge for doors, which is structurally perfected and wherein at least one of the main components presents a structure that is simply obtained from a material having high mechanical performance and obtaining a considerable saving of the same material.
  • One object of the present invention is to obviate the above drawbacks, by providing an invisible hidden hinge for doors, which is structurally perfected and wherein at least the support structure is configured so as to be simply obtained from a material having high mechanical performance and obtaining a considerable saving of the same material.

  • One object of the present invention is to obviate the above drawbacks, by providing an invisible hidden hinge for doors, which is structurally perfected and wherein at least the structure of a movable insert and/or of a movable body is configured in such a way as to make possible to simply realize therein a seat for the insertion of a head of an adjusting actuator, the movable insert and/or the movable body and said seat being obtained from a material having high mechanical performance, at the same time realizing a considerable saving of same material.
  • One object of the present invention is to obviate the above drawbacks, by providing an invisible hidden hinge for doors, which is structurally perfected and wherein at least a part of the articulation device is configured so as to be simply obtained from a material having high mechanical performance and obtaining a considerable saving of the same material.

  • the second connecting body 2b develops: in depth along a fourth direction X2 in space coincident with the direction of insertion in the respective housing cavity in the door jamb or leaf; in width along a fifth Y2 direction in space perpendicular to the fourth direction X2; in length along a sixth Z2 direction in space perpendicular to both the fourth X2 and the fifth Y2 direction.
  • the first direction X1 is then the direction of the depth X1 of the first connecting body 2a, while the fourth direction X2 is the direction of the depth in the second connecting body 2b;
  • the second direction Y1 is the direction of the width of the first connecting body 2a, while the fifth Y2 direction is the direction of the width of the second connecting body 2b;
  • the third direction Z1 is the length direction of the first connecting body 2a, while the sixth direction Z2 is the length direction of the second connecting body 2b.
  • the first 2a and the second 2b connecting body define, in mutual combination, a seat in which the articulation device 3 is enclosed.
  • the first 2a and the second 2b connecting body have two sides 21a, 22a; 21b, 22b opposed to each other with respect to a plane defined by the direction of the depth X1, X2 and by the direction of the length Z1, Z2.
  • the inner one 21a, 21b is the side that, in the movement of opening-closing of the hinge 1, travels a shorter path, the outer one being the other 22a, 22b.
  • the first 2a or the second 2b connecting body comprises a supporting structure 4a, 4b.
  • both the first 2a and the second 2b connecting body comprise a respective supporting structure 4a, 4b.
