Definitions

  • the present invention relates to a hinge system configured to move a door, shutter or similar element.
  • the present invention relates to a hinge system configured to move a door from a closed configuration to an open configuration and vice versa.
  • the present invention relates to a hinge system configured to move a flush type of door, for example, in the case of a door of a sunroof of a car or a door of a storage compartment of a motorhome, caravan or boat.
  • door, shutter or similar element refers here to an element for closing an opening or a passage in a wall, for example, of a motor or self- propelled vehicle where there is the need for a closure that meets certain aesthetic criteria in addition to those of efficiency and comfort.
  • Hinge systems for moving doors and shutters of an opening that substantially comprise two fastening plates or elements, fixed, respectively, one to the door and one to the fixed frame of the opening and joined to one another by means of a pin so as to form the pivotal joint to permit a pivotal movement of the door with respect to a fixed frame, are known in the prior art.
  • the prior art hinge systems may have a somewhat complex architecture and comprise numerous components to enable the equally complex kinematic control of doors which must perform rotational-translational movements when opened/closed.
  • the prior art hinge systems are generally large with an overdimensioned structural architecture, also to improve the mechanical strength of the components.
  • the prior art hinge systems have a number of drawbacks which limit their use and reliability.
  • the prior art hinge systems are never completely hidden from view, that is to say, they are configured in such a way that when the door is open or closed some elements of the system are always visible or exposed on the outside of the door.
  • the prior art hinge systems are also rather delicate and fragile: if one of the external, exposed components of the system is hit or damaged, it might prevent the correct closing and/or opening of the door. It is worth noting that flush hinge systems have been developed, that is hinge systems which are aligned with the window or door surface without protruding externally from this surface, but these have a number of drawbacks including, for instance, the fact that they cannot guarantee a perfectly watertight and dust-proof seal and are not theft and/or sabotage- proof.
  • flush type hinge systems are known in the prior art which do not prevent the ingress of water, especially the fine water spray generated by high-pressure washers and/or fixed automatic washing plants.
  • the build-up and penetration of water through the known flush hinge system results in damage to the parts close to the door and oxidation of the mechanical components of said hinge system.
  • the purpose of the present invention is to overcome the problems that have been found in the prior art by proposing a hinge system configured to move a door that is compact and completely enclosed.
  • the purpose of the present invention is to provide a hinge system configured to move a door that comprises only a few elements which are easy to produce, so as to limit production costs.
  • a further purpose of the present invention is to provide a hinge system configured to move a door which makes it possible to reduce the costs and time required for maintenance.

  • the hinge system comprises at least a first pin extending along a first axis of the connecting body and configured to provide a pivotal connection about the first axis between the first coupling element and the connecting body.
  • the hinge system comprises a second pin extending along a second axis configured to provide a pivotal connection about the second axis between the second coupling element and the connecting body.
  • the first axis and the second axis are staggered so as to be arranged at respective different distances from a closing plane defined by the door and by the fixed frame in a closed configuration of said door.
  • the door and the fixed frame In order to move relative to each other without interfering with each other, the door and the fixed frame, in a closed configuration of the door, present a passage or little distance between them. This distance is, in some parts along the perimeter of the door, filled by the hinged system of which only the top profile is visible, while remaining in a flush configuration with the closing plane of the door aligned with the fixed frame.

  • the compact structure of the hinge system according to the present invention is extremely robust thanks to the arrangement of the coupling elements at the free ends of the connecting body of said hinge: the large distance between the coupling elements compared with the prior art hinges enables a better distribution of the forces and loads on the connecting body and on all the elements of said hinge, which is thus more resilient to any uncontrolled opening of the door, for example in the case of the door being pushed by a gust of wind.
  • the hinge system according to the present invention has a simplified structure which means production costs can be kept low despite achieving numerous advantages in terms of functionality and use, as listed below.
  • the hinge system according to the present invention has coupling elements with at least one point for fixing/assembly (by means of screws or other systems) and is therefore more robust and has a greater load capacity (in terms of weight of the movable door) than the prior art hinge systems.
  • the hinge system according to the present invention is more secure and resilient to possible break-ins and sabotage by ill- intentioned people attempting to force the door open, thanks to the very small opening between the door and the fixed frame.
  • the hinge system according to the present invention is configured to provide very good protection against bad weather conditions (rain, freezing conditions and draughts) and/or against high-pressure jets of water or water sprayed by automatic car-wash systems or high-pressure washers, thus also protecting the internal components of the system and other fittings of the door.
  • the hinge system according to the present invention is configured to offer a high level of comfort in terms of airflow and other noises that could enter through the door. Thanks to the extremely limited opening between the movable door and the fixed frame, the annoying and undesirable aerodynamic and/or airflow noises, for example when the vehicle is travelling at high speed, can be considerably reduced and in some cases eliminated.
  • the hinge system according to the present invention incorporates effective power assistance means so that the user is required to apply less force when performing the manual operation to close and/or open a door of a luggage compartment or of an opening.

Le système de charnière (1) comprend au moins une première broche (30) s'étendant le long du premier axe (X) et une seconde broche (40) s'étendant le long d'un second axe (Y). Le premier axe (X) et le second axe (Y) sont décalés de manière à être disposés à des distances respectives différentes (D1, D2) depuis un plan de fermeture (F) défini par la porte (100) et par le cadre fixe (200) en configuration fermée de la porte (100).
