  • FIG. 14 a perspective view of a rocking support as modified with respect to that in FIG. 13;
  • FIGS. 15 and 16 two exploded perspective views for alternative structural details
  • FIG. 17 a view similar to that of FIG. 9, but showing the hinge at a closed position
  • FIG. 18 a sectional detail for spring adjustment.
  • the quadrilaterally articulated invisible hinges generally comprise a fixed hinge portion 19 and a moving portion 20, the former being secured to the fixed furniture portion 21, and the latter being made fast with the door or flap and the like to be closed or opened by the user.
  • the two portions are connected and articulated as a. quadrilateral by two equalizer plates 23 and 24 respectively pivoted at 25 and 26 on fixed portion 19 and at 27 and 28 on the moving portion of the hinge.
  • the spring member for the hinge device comprises a cylindrical helical spring, designated at 29 and seating within a cap 30 fast with the fixed portion 19 of the hinge and projecting therefrom.
  • a small ball 31 is acconnnodated, this small ball 31 being held by rivetting 32 on the lower opening of cap 30, so that under the action of spring 29 said small ball 3-1 only slightly projects from said rivetting.
  • Cap is provided with a retaining collar 30 for locking thereof with respect to said fixed element 19 of the hinge.
  • Cap 30 can be made by bar turning, die-casting or injection moulding.
  • the cap, carrying in this case a mark or reference 31, may be made by sheet drawing.
  • the cap here designated at 32 has the bottom thereof comprising a screw 33 allowing, even when the hinge has been installed, to adjust the reaction strength of spring 29, as desired, by compressing it through more or less screwing of screw 32 relative to the side walls of cap 32.
  • the spring returns a portion of the spring potential energy which, as set forth in the following, it had stored during the last closing preceding the opening being involved, imparting a moment to equalizer 24 which tends to close and to retain the hinge closed and hence the door or flap connected thereto.
  • equalizer 24 rotates about its pivot 26 in the direction bringing its cam 24' to press against said small ball 31 causing it to re-enter its cap 30, compressing spring 29, thus storing energy available for locking the door or flap at the end of a next closing movement.
  • FIGS. 9-18 there is shown a different embodiment of the device.
  • the automatic locking assembly comprises a cylindrical helical spring 33 inserted on a guide stem 34, the latter being slidable within a hole 35 in the end wall of the fixed element 19 of the hinge, at its area facing the roller said stem 34 having an enlargement 34 serving as abutment for an end of spring 33 and at its end carrying a sag 36 for coupling with pin 37 of roller 38.
  • the spring assembly may comprise two stems 34a on which two springs 33 are inserted. These stems are parallel to each other and provided similarly to the above with enlargements 34' with sags 36, said two stems being connected by bridge 39.
  • roller 38 is freely rotatable about its pin 37 fast with support 40 which is freely rockable about pin 41 fast with the fixed element 19 of the hinge.
  • Said rocking support 40 has two symmetrical side walls provided with holes 42, through which said pin 41 passes, said support being capable of rocking about the latter, and holes 43 passed through by pin 37 of roller 38.
  • Support 40 also has inclined sections 44 allowing for accommodating the head and riveting of pin 37, and bridge 45 connecting the above-mentioned two symmetrical side walls to each other.
  • FIG. 14 shows a modified form of support 40" with respect to support 40: therein, the two side walls are connected by a bridge 45' which is sidewise located relative to said side walls.
  • support 40 it being however understood that the matter as set forth also applies for support 40'; thus, whatever its shape may be, support 40-40 always performs a guide function for the roller.
  • a sleeve 46 preferably of antifriction material, adapted to be inserted between roller 47 and pin 37.
  • two identical bushes 48 also of antifriction material and provided at an end with a flange are adapted to be symmetrically inserted in roller 47 between the roller itself and pin 37.
  • sleeves or bushes of antifriction material can be applied to one or more of pivotings 25, 26, 27 and 28 forming the knots of the articulated quadrilateral incorporated in the hinge.
  • FIG. 18 there is shown a threaded bush 49 adapted to be screwed within a threaded hole 35' in the end wall of the fixed element 19' of the hinge.
  • the end of spring 33 bears against this bush 49 and, accordingly, by more or less screwing down said bush, a more or less precompression and hence a more or less strength of said spring will be achieved.
  • said equalizer 24 When the hinge begins to close, said equalizer 24 first rotates almost imperceptibly about its pin 26, then with increasing speed until, adjacent the closed position of the hinge, roller 38 commences to go beyond the rim of cam 24 and accordingly, as urged by spring 33, tends to approach the axis of pin 26. At the same time, support 40 rocks about its fixed pin 41 maintaining said roller 38 in contact with the rim of cam 24'.
  • An articulated invisible hinge for a door comprising a stationary hinge element to be secured .to the internal surface of a stationary member adjacent the door, said stationary hinge element having the form of an elongated channel closed at one end and having fixed thereto a pair of spaced transverse pivots at the opposite end thereof, a swingable hinge element to be secured in a cavity of the door to be opened and closed, said swingable hinge element having fixed thereto a second pair of spaced transverse pivots, a pair of arch-shaped spacing links interconnecting one pivot of the first pair to one pivot of the second pair, the innermost spacing link being provided with an extension beyond the stationary pivot which acts as a cam surface, a guide located in the closed end of the stationary hinge element, a shaft slidable in said guide and having an enlarged terminal portion the leading surface of which forms a seat, an elastic compressible means positioned on said shaft between the enlarged terminal portion thereof and the closed end of the stationary hinge element, an oscillating member mounted in said stationary hinge element substantially perpendicular to said shaft, a
