Definitions

  • the present invention in its most general aspect, relates to articulated hinges with snap-type movement in the opening and closing phases.
  • hinge-supported doors Such movement is used for keeping hinge-supported doors more firmly in the opening and closing conditions; the use of this type of hinges is known above all for applications where furniture (wardrobes, hanging cabinets, etc) is installed in environments subject to shocks and vibrations, such as road transport means (vehicles, vans, trailers, caravans and the like), boats and so on.
  • furniture downwardrobes, hanging cabinets, etc
  • shocks and vibrations such as road transport means (vehicles, vans, trailers, caravans and the like), boats and so on.
  • Hinges of the type mentioned above allow the cabinets to be opened or closed by rotating the door by about 90° with respect to a horizontal axis, such to bring it in a opened and raised condition, leaving it in such condition even in case of small shocks or vibrations due to the movement of the vehicle where the cabinet is located.
  • hinges different than those intended for home furniture are used, since they must have small dimensions as the spaces available on vehicles, and therefore on wardrobes, are usually quite limited; however at the same time hinges have to provide a force suitable for supporting the weight of the door even in the opened condition such as a door leaf, in addition to keeping it firmly closed in spite of the shocks and vibrations to which a transport vehicle can be subjected.
  • the hinges to which the present invention particularly relates have mechanisms composed of articulated polygons (quadrilaterals and the like) secured to a door and to a wall of the piece of furniture, connected to each other by elements in common, such as connecting rods, rocker arms or the like.
  • hinges have been known for a long time and an example can be found in the European patent EP 1138857 , where an hinge is described whose snap movement opening and closing the door is the result of the action of two springs acting on respective articulated quadrilaterals that compose the hinge; while as regards the efficiency of the opening and closing phases of the door of the piece of furniture such hinge provides satisfactory performances, the provision of two springs one of which in addition provided outside the hinge mechanism, is a limit both as regards hinge costs, and as regards safety aspects of the mechanism. It can be appreciated that the provision of a spring outside the hinge mechanism is an element of possible interference with the hands of the users opening and closing the cabinet door.
  • This application describes a hinge with no springs outside the hinge mechanism, namely arranged outside the assembly of levers and other elements constituting the articulated quadrilaterals, by the use of an insert 19' that under the elastic action of some springs 21' housed therein, allows a pivot 17' to be engaged which helps in stabilizing the configuration of the hinge in the opened and closed condition of the door.
  • this hinge avoids providing springs outside the hinge (as in EP 1138857 ) with the advantages that derive therefrom; however, the use of an insert 19' and of elastic means 21' cooperating with the other elements of the hinge in order to guarantee the performances required by the latter, is an aspect that requires an additional cost as regards the production, with reference both to its manufacturing per se, and with reference to the general assembling of the hinge.
  • the technical problem at the base of the present invention is to provide a snap-type articulated hinge of the type mentioned above, which has such structural and functional features to overcome the drawbacks set forth above.
  • the present invention provides to make a hinge with a snap-type movement which has a structure simplified with respect to the known hinges, at the same time achieving improved performances as regards the opening and closing movements, suitable for hinges for furniture intended particularly but not exclusively for transport means in general such as vehicles, caravans, vans, boats and the like.
  • the idea solving the problem set forth above is to make a hinge with elastic means that mainly act upon the opening and closing conditions of the door, such to guarantee such conditions to be reliably maintained, however without exerting a significant force in conditions intermediate between these two extreme ones.
  • a hinge according to the invention is generally denoted by 1, which is of the snap-type with two articulated quadrilaterals having some elements in common.
  • the hinge I has two fastening plates 2 and 3 intended to be secured (by means of screws) to a wall P and to the door A respectively of a piece of furniture, such as a hanging cabinet or the like; generally two hinges are provided for mounting the door and the opening and closing movements of the door occur by means of a roto-translation with respect to a horizontal axis (that is perpendicular to the plane of the sheet).
  • the door is raised and lowered likewise a door leaf for being opened and closed; however what is described below shall be considered as valid also if the axis of rotation of the door is vertically arranged.
  • the plates 2 and 3 of the hinge I are arranged perpendicularly each other, while with the door in the open condition (shown in fig.6 ) they lie substantially coplanar to each other.
  • a base 4 is integral with the plate 2, which represents the frame or fixed side of an articulated quadrilateral and that comprises two rocker arms 5 and 7 connected to each other by a connecting rod member 6, which is the end portion of one of the rocker arms 8 of the second articulated quadrilateral of the hinge.
  • the second quadrilateral comprises two rocker arms 8, 10 connected by a connecting rod member 9 composed of a portion of the rocker arm 7, and the plate 3 represents the last side thereof; since the connecting rod member 9 is a portion of the rocker arm 7 of the first quadrilateral, it is clear that the two quadrilaterals have some elements in common which connect them kinematically to each other. Therefore, to summarize, the first quadrilateral comprises the base 4, the rocker arms 5, 7 and the connecting rod member 6, articulated at the vertex pivots 11, 12, 13 and 14; the second quadrilateral comprises the rocker arms 8, 10 and the connecting rod member 9, articulated at the vertex pivots 13,15,16 and 17.
  • the latter in this example are composed of a spring housed into the usual telescopic enclosure known for such applications (see EP 1 138 857 ); however different elastic means can be provided, such as those obtained by elastomeric members instead of the spring, or in combination thereto.
  • the spring 20 cooperates in such a manner to cause the hinge to stop with a snap action in the opening and closing conditions of the door A of the piece of furniture; concerning this it has to be pointed out how in the hinge 1 of the invention only one of the articulated quadrilaterals is associated to the elastic means 20, such to simplify the overall structure of the hinge and consequently, its assembling.
  • the base 4 has a projecting head 22, shaped with a cam profile 23 faced outwardly of the hinge and a concave seat 24 in the part faced inwardly.
  • the spring 20 during the opening and closing phases of the hinge 1, cooperates with the head 22 such to exert an elastic force on the quadrilateral articulated with the base 4, since it is integral with the first rocker arm 5 and it is articulated at the vertex 12 of the quadilateral having the articulation pivots 11, 12, 13 and 14.
  • the shape and the dimensions of the head 22 and those of the elements of the articulated quadrilaterals, namely the base 4, the rocker arms 5, 7 and the connecting rod member 6 for one quadrilateral, and the plate 3, the rocker arms 8, 10 and the connecting rod member 9 for the other quadrilateral, are such that the elastic force exerted by the spring 20 has a substantially constant trend in a prevalent central part of the rotation of the hinge 1, while it increases at the extremes upon the opening and closing conditions.
  • fig.8 is a diagram where the abscissa shows the opening angle of the hinge (for convenience purposes the condition of the hinge in the several steps is shown under the diagram), while the ordinate shows the elastic force exerted by the spring (that in practice is proportional to the deformation of the spring according to the known Hooke's Law).
  • the trend of the force reaches the maximum value with the door in the opened condition, namely for an angle of about 90°; from the diagram it can be appreciated how such value is about 2,5 times higher than that of the force exerted by the spring at the central opening (or closing) area of the hinge; this allows the door to remain firmly opened, even in case of shocks or vibrations such as those that may affect furniture on vehicles.
  • the force exerted by the spring after its deformation however increases upon the closing condition of the door, as it can be seen in the left area of the diagram; this allows the door to be kept firmly closed, preventing it from being undesirably opened due to accidental reasons.
  • the change in the force applied by the spring 20 is mainly due to the cam mechanism composed of the profile 24 of the head 22, cooperating with the spring 20; the seat 23 in addition gives stability to the door closing condition, since it is engaged by the spring 20 when reaching such condition.
  • Figures 9 and 10 show diagrams showing in an enchanced comparative manner the behaviour of the hinge 1 according to the invention and that of a prior art hinge as those mentioned above, with the door in the opening and closing conditions respectively.
  • the force for opening the door that in the hinge I is determined by the cam mechanism composed of the spring 20 and the profile 24, takes a maximum value after few degrees of rotation (about 10°), that is very lower than that of the known hinge.
  • the elastic means 20 can be different than the spring with telescopic enclosure mentioned above, which however has the benefit of being simple and, therefore, inexpensive.
  • the spring may be replaced by elastic means made of elastomer (rubber), or can be integrated with a roller arranged at the end and intended to act on the cam profile 24.
  • Other variants can be obtained by modifying the number and/or the shape of the articulated members.
  • the behaviour of the hinge is adjusted by a screw 30, passing through the head 22 with the cam profile 24: by tightening or loosening the screw 30, one acts on the spring 20, which is more or less urged.
  • lever 32 carries out the same functions of the screw 30 as in the previous variant, it is just that instead of tightening or loosening the screw in this case it is the lever 32 to be rotated.
