Definitions

  • the present invention has as its subject-matter a hinge for pieces of furniture, which can be used for example in doors or shutters of furniture or electrical appliances such as refrigerators, freezers and so on.
  • movable-axis hinges As is known, for the purpose of satisfying requirements of movement and juxtaposition between the various panel-shaped units that constitute a piece of furniture or an electrical appliance equipped with one or more doors/shutters, use is very frequently made of what are known as “movable-axis hinges", which generally connect a “fixed part” to a “moving part” and allow the latter to be moved in space using a rotary-translational movement action in which the axis of rotation itself does not have a fixed position but moves in its turn.
  • movable-axis hinges therefore have two coupling units for the fixed parts and the moving parts, and within these two coupling units there is an appropriate kinematic mechanism that defines the action of moving the moving part and, consequently, the (ideal) axis of rotation around which the moving part (or "door”) moves when opening and/or closing.
  • movable-axis hinges of the known type are generally somewhat complex in the structure of the kinematic mechanism, which in turn is based on a large number of parts hinged together: for example, it is not infrequent to find movable-axis hinges provided with seven pivots, which therefore suffer from great structural complexity and high cost.
  • WO 83/02299 A1 discloses a hinge according to the preamble of the attached main claim.
  • the main aim proposed by the present invention is, therefore, to devise a movable-axis hinge for furniture doors and the like capable of overcoming the above-mentioned disadvantages.
  • the aim of the present invention is to devise a movable-axis hinge that allows the structure to be definitely simplified, while ensuring said functionality with respect to the more complex hinges of the known type (either in terms of maximum angle of opening, or in terms of identifying the trajectory of the ideal axis of rotation of the door, or indeed in terms of adaptability to various types of doors for furniture or refrigerators or similar objects).
  • the present invention also has the aim of producing a movable-axis hinge that allows greater efficiency of the actual assistance device and, in particular, makes it possible to achieve improvements in either the closing movement or the opening movement.
  • a further aim of the present invention is to provide a hinge that is economical and reliable to manufacture, and is also very easy to assemble (also taking account of the need for an assistance device to be installed inside) and to be implemented inside a piece of furniture or an electrical appliance such as a refrigerator or the like.
  • the hinge according to the present invention is designated as a whole by the number 1 in the attached figures, and it mainly comprises a first coupling unit 2 (connectable to a fixed part of a piece of furniture or the like) and a second coupling unit 3 (connectable instead to a moving part of a piece of furniture or the like); a kinematic movement mechanism 4 is also present, interposed and hinged between the first coupling unit 2 and the second coupling unit 3 and is capable of reversibly configuring what is known as the "moving part" (in other words, the "door”) between a closed state and an open state.
  • a kinematic movement mechanism 4 is also present, interposed and hinged between the first coupling unit 2 and the second coupling unit 3 and is capable of reversibly configuring what is known as the "moving part" (in other words, the "door”) between a closed state and an open state.
  • an assistance device 5 that acts, operationally, on the kinematic movement mechanism 4, which is reversibly configurable between an assisted closing state shown in figure 6 (in which it exerts an action of drawing back the moving part towards the fixed part) and a stable state shown in figure 5 (in which instead it exerts at least an action of holding the moving part in position at at least a given angle of opening with respect to the fixed part).
  • the present invention incorporates two functions that are complementary with one another, and this functional integration is implemented in a single device mounted inside said hinge.
  • the assistance device 5 is reversibly configurable between the above-mentioned “assisted closing” and “stable” states corresponding to at least one predetermined critical angle of partial opening of the moving part with respect to the fixed part: in particular, the assisted closing state occurs (and remains “active") between a minimum angle of closing of the moving part with respect to the fixed part (or in other words, starting from a minimum or zero angle of opening) and within the above-mentioned critical angle of partial opening, while the stable state occurs (and remains "active") between the critical angle of partial opening and a maximum angle of full opening of the moving part with respect to the fixed part.
  • the assistance device 5 can be reversibly configurable (also) in a state of assisted opening corresponding to what is known as a "complementary threshold angle".
  • this further function of the present invention can be implemented in correspondence to a complementary threshold angle that coincides with the critical angle of partial opening: in this way, while the simple "holding” function provides for the moving part (or “door”) to be held in a stable position of partial opening, the (additional and optional) assisted opening function facilitates movement of said door, which can then be opened with less effort.
  • any critical angle of partial opening (and/or, if necessary, any complementary threshold angle) can be chosen: for example, the critical angle of partial opening can correspond substantially to half the value of the maximum angle of full opening.
  • the kinematic movement mechanism 4 comprises (and preferably includes, for the purposes of introducing the maximum structural simplicity), a first pivot 4a and a second pivot 4b, which are connected to the first coupling unit 2; a first arm 4e is then present (mounted rotatably on the second pivot 4b and having a third pivot 4c at one of its ends opposite said second pivot 4b) and a second arm 4f is also present (which in turn is rotatably mounted on the first pivot 4a and has a fourth pivot 4d at one of its ends opposite said first pivot 4a).
  • the second coupling unit 3 is connected to the third pivot 4c and the fourth pivot 4d (and consequently is connected to the first and second arms described above).
  • the assistance device 5 comprises an elastic reaction unit 5a, preferably pre-loaded and even more preferably constituted by an axial spring (or also by a pressurised fluid): such an elastic reaction unit 5a is interposed operationally between the first arm 4e and the second arm 4f, and its dynamic/kinematic action varies, as already stated, when the angular position of said two arms varies with respect to the coupling units 2 and 3.
  • an elastic reaction unit 5a preferably pre-loaded and even more preferably constituted by an axial spring (or also by a pressurised fluid): such an elastic reaction unit 5a is interposed operationally between the first arm 4e and the second arm 4f, and its dynamic/kinematic action varies, as already stated, when the angular position of said two arms varies with respect to the coupling units 2 and 3.
  • the elastic reaction unit 5a is capable of generating an elastic reaction force aligned along an operating direction, and the course of application of such an elastic reaction force can conveniently be inverted (or even cancelled out, if need be) in correspondence to the critical angle of partial opening and/or in correspondence to the complementary threshold angle.
  • the assistance device 5 can also comprise motion-damping means, preferably of the viscous type, which can be activated operationally between the first coupling unit 2 and the second coupling unit 3 and preferably between the first arm 4e and the second arm 4f: these damping means can in turn comprise a fluid-type damper or can be based on surfaces in mutual friction.
  • the motion-damping means comprise a damper mounted coaxially with the elastic reaction unit 5a and composed of a sleeve and a stem, as will be explained in detail below: in effect, the assistance device 5 comprises the following list of parts:
  • the assistance device 5 also to comprise assembly means 8 that can be activated operationally between the support sleeve 5b and the support stem 5c and are capable of supporting and pre-loading the elastic reaction unit 5a.
  • such assembly means 8 ( figures 8 and 9 ) comprise a predetermined number of reciprocally countershaped engagement units, and the engagement units in turn can comprise undercuts and/or expansions and/or threads and/or counter-threads that are mutually complementary.
  • the above-mentioned engagement units are made in the support sleeve 5b and the support stem 5c respectively, so that partial assembly of said sleeve and said stem allows the coupling and pre-loading of the elastic reaction unit 5a to be produced simultaneously.
  • pretensioning means can also be present, capable of minimising and/or cancelling out any persistent play between the pivots 4a, 4b, 4c, 4d, the arms 4e and/or 4f and the coupling units 2 and/or 3 in operating states.
  • the above-mentioned pretensioning means can coincide with the assistance device 5).
  • the present invention can comprise travel-limitation means 6 for the opening and/or closing of the moving part with respect to the fixed part: structurally, these travel-limitation means 6 can comprise at least one matching body mounted on the first arm 4e (or, according to the demands of the moment, on the second arm 4f) and capable of interfering with the assistance device 5 corresponding to a limiting angle of opening of the moving part with respect to the fixed part.
  • the present invention can finally provide the presence of appropriate assembly means 7, which are capable of allowing said hinge 1 to engage with a fixed part and/or a moving part.
  • these assembly means 7 are capable of permitting the engagement of the hinge 1 in one of its partial or full closing configurations (as distinct from the known type of hinges, which can be mounted only if they are in the fully open or fully closed configuration) and preferably comprise through-holes and/or cavities made in the coupling units 2, 3 and/or in the arms 4e, 4f , suitably aligned.
  • the aforementioned cavities are capable of defining an access and operation axis 7a for a tool (a powered screwdriver or the like) corresponding to a partially or fully closed configuration of the hinge 1, so that an operator/assembler can handle the hinge 1 with the greatest freedom and can operate efficiently and conveniently through this access and operation axis 7a in order to insert first screws or nails and, later on, the tool itself.
  • a tool a powered screwdriver or the like
  • the movable-axis hinge passes from the closed configuration of figure 6 (in which the assistance device 5 is not shown for sake of clarity) to the open configuration of figure 5 .
  • the elastic reaction unit or spring 5a is progressively compressed up to a predetermined degree of rotation corresponding roughly to the configuration in which both pivots 4a and 4b are substantially aligned with the fourth pivot 4d.
  • the force of the spring 5a contributes towards such opening (i.e. the spring 5a expands) up to the full opening configuration of figure 5 in which the spring 5a keeps the hinge in an open configuration.
  • Such “inversion” of the action of the spring is due to the geometry and shape of the arms 4e and 4f and the position of the pivots.
  • the first pivot 4a and the second pivot 4b of the first coupling unit 2 reach a position (not shown) in which they are substantially aligned with the fourth pivot 4d of the second coupling unit 3.
  • the distance between the feet 5d and 5e of the assistance device 5 is the lowest (i.e. maximum force action of the spring 5a).
  • the first pivot 4a moves towards a position which is further with respect to a line joining the second pivot 4b and the fourth pivot 4d, on the side far from the second coupling unit 3 (configuration shown in figure 5 ).
  • the invention achieves advantages that are of interest.
  • the present invention has a further, remarkable advantage in that the assistance device can be utilised in either the opening movement or the closing movement of the door, considerably increasing operational flexibility and, consequently, the freedom of action of the end user of the piece of furniture (or refrigerator) when he acts on the door.
  • the present invention permits rapid and efficient assembly of the hinge, and at the same time permits equally easy assembly thereof on the fixed and/or moving parts.
  • the present invention makes it possible to achieve great reliability, considerable structural simplification and minimisation of production and maintenance costs.
