Definitions

  • the present invention concerns a recessed hinge or retractable hinge, to articulate a mobile part, such as for example a door, or the closing element of a piece of furniture, with respect to a fixed part, such as for example the corresponding door jamb, or the fixed frame of the furniture, so that, in the closed position, the hinge is substantially not visible from the outside.
  • recessed or retractable hinges In the field of door or window frames and furniture, so called recessed or retractable hinges are known, which, as well as allowing the articulation of a mobile part with respect to a fixed part, have their components disposed inside the two articulated parts, fixed and mobile, so that when the mobile part is in the closed position, the components of the hinge are not visible from the outside.
  • a hinge in which a connection element is pivoted, along vertical pivoting axes, both to the first containing body and to the second containing body, the latter both associated to the mobile and fixed parts.
  • the connection element comprises two toothed wheels engaging with each other, pivoted along respective axes of rotation parallel to the two vertical pivoting axes as above.
  • Each containing body comprises a circular toothed sector, which develops around the vertical pivoting axes.
  • the toothed wheels engage with each other and each one also engages with one of the circular toothed sectors.
  • this known hinge has the disadvantage that it leaves too marked a gap between the fixed part and the mobile one, when the latter is in the closed position, which in practice renders the components of the hinge visible from the outside. This occurs because the pivoting axes of the end parts of the connection element are fixed with respect to the containing bodies.
  • One purpose of the present invention is to obtain a hinge, of the recessed type which as well as allowing an aperture of 180° of the mobile part with respect to the fixed part, reduces to a minimum the gap between the two mobile and fixed parts, even when the latter is in the closed position, so the components of the hinge are practically not visible from the outside.
  • Another purpose of the present invention is to obtain a hinge provided with simple components to make, which is able to support relatively high loads, and which is not very bulky or costly.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a hinge of the recessed type according to the present invention which overcomes the limits of the state of the art and eliminates the defects present therein, is able to articulate a mobile part, such as for example a door, or the closing element of a piece of furniture, with respect to a fixed part.
  • the hinge according to the present invention comprises two containing bodies, shaped so as to each have a compartment and suitable to be associated one to the fixed part and the other to the mobile part.
  • An articulation member articulates the containing bodies with respect to each other.
  • each of the containing bodies, inside the corresponding compartment is provided at least with a rack, with a support surface, which acts as a sliding block, parallel to the rack, and with a guide parallel to the support surface.
  • the articulation member comprises a connection element with two ends, each of which is provided at least with a first toothed sector, engaging with the corresponding rack of one of the containing bodies.
  • a toothed element is mounted, with a pin able to slide inside the corresponding guide and provided with a flat surface which cooperates with the support surface, in order to slide with respect to it, and a second toothed sector.
  • the two toothed elements located at the two ends of the connection element are connected to each other by means of a train of gears.
  • This transmission system with its toothed wheels renders coherent the movement of the two ends of the connection element, so that the linear movement of one of the ends of the connection element, with respect to the corresponding containing body, is identical to that of the other end with respect to the corresponding containing body.
  • the recessed hinge according to the present invention unlike those in the state of the art, causes the mobile part to be disposed, in the closed position, at a greatly reduced distance with respect to the fixed part. Moreover, there is also the advantage that, in said closed position, the connection element, including the train of gears, is practically all inside the compartments made in the containing bodies, and therefore not visible from the outside.
  • the hinge according to the present invention obtains a greater distance of the mobile part with respect to the fixed part.
  • a hinge 10 of the recessed or retractable type comprises two containing bodies 11 and 12, one solid to a fixed part 13 ( figs. 5 , 6 and 7 ), such as for example a door jamb, or the structure of a cupboard, and the other solid to a mobile part 14, such as for example the corresponding door or closing element.
  • the hinge 10 is symmetrical, and therefore it is irrelevant which of the containing bodies 11 and 12 is associated to the fixed part 13 or to the mobile part 14.
  • connection element 18 substantially C-shaped and which will be described in detail hereafter.
  • the two containing bodies 11 and 12 comprise two corresponding compartments 23 and 24, in which the connection element 18 is disposed, only partly when the hinge 10 is in the open position and completely when the hinge 10 is in the closed position.
  • Two racks 35 and 36, parallel to each other, are made on two lateral walls 29 and 30 of the two compartments 23 and 24.
  • a support surface 41 is made, respectively 42, which in the specific case is about half way up the height of the corresponding compartment 23 and 24.
  • two rectilinear guide eyelets 43 and 44 are made ( fig. 2 and figs. from 5 to 10), aligned and parallel to each other, which act as a guide for two corresponding pins 61, respectively 62 of the connection element 18.
  • connection element 18 is shaped so as to have two ends 49 and 50 of a partly circular shape and provided with corresponding first toothed sectors 53 and 54, the teeth of which constantly engage with the respective racks 35 and 36.
  • each first toothed sector 53 and 54 is substantially the same as that of the corresponding rack 35 and 36 with which it engages.
  • the pins 61 and 62 are positioned substantially at the center of the ends 49 and 50 of the connection element 18 and are free to slide inside the pairs of guide eyelets 43 and 44.
  • Two toothed elements 65 and 66 are also pivoted on the pins 61 and 62, each of which toothed elements 65 and 66 has substantially the shape of a toothed wheel, from which a part has been removed, tracing a chord which defines a flat surface 69, respectively 70, and a second toothed sector 71 and 72. In this way the toothed elements 65 and 66 are coaxial to the toothed sectors 53 and 54.
  • the flat surfaces 69 and 70 of the two toothed elements 65 and 66 are suitable to slide on the support surfaces 41 and 42 made inside the compartments 23 and 24.
  • connection element 18 also comprises a compartment 76, inside which a train of gears 75 is disposed, in this case comprising six intermediate toothed pinions 74 and two end toothed pinions 74a and 74b.
  • a train of gears 75 in this case comprising six intermediate toothed pinions 74 and two end toothed pinions 74a and 74b.
  • all the toothed pinions 74, 74a and 74b are disposed in sequence, engaging with each other, and connecting the toothed element 65 with the toothed element 66.
  • Each toothed pinion 74, 74a and 74b is mounted on pins 77 mounted on the connection element 18 and parallel to the pins 61 and 62.
  • the compartment 76 of the connection element 18 is closed with a lid or guard 80 at the front part.
  • the hinge 10 as described heretofore functions as follows.
  • the hinge 10 ( figs. 4 and 5 ) is completely inside the fixed part 13 and the mobile part 14, including the connection element 18.
  • the two containing bodies 11 and 12 are gradually distanced from each other, while the toothed elements 65 and 66 slide, with their flat surfaces 69 and 70, on the support surfaces 41 and 42.
  • the pins 61 and 62 are guided by the guide eyelets 43 and 44, and because the two toothed elements 65 and 66 are connected to each other by means of the train of gears 75, a rotation-translation of the ends 49 and 50 of the connection element 18 is obtained, until, remaining constantly in symmetric positions with each other, that is, with their pins 61 and 62 both positioned inside the guide eyelets 43 and 44, in the maximum open position, the connection element 18 is almost all outside the two compartments 23 and 24 of the containing bodies 11 and 12.
