Definitions

  • the present invention relates to a hinge, in particular for armour-clad doors.
  • the hinges particularyly intended for armour-clad doors, or the like show a particularly strong structure, in order to be able to resist to the stresses they undergo whenever the heavy door they support is opened or closed.
  • the present hinges comprise a female element integral with the door, and a male element integral with the doorpost, provided with a pivot on which a rolling thrust bearing is slid, with said bearing resulting thus compressed between the female element and the male element
  • the overall dimensions of the bearing must mandatorily be limited within narrow limits, in that said bearing must be housed inside the small toroidal room existing between the outer surface of the pivot on which it is slid, and the external surface of the hinge, which coincides with both the outer surface of the male element, and the outer surface of the female element which, when assembled with each other, compose the same hinge.
  • the diameter of the rolling bodies of the bearing is very small, so that said rolling bodies generate high specific pressures on the relevant races, with the result that such races wear out very early, requiring the whole bearing to be frequently replaced.
  • an improved type of such a hinge is provided with means of adjustment of the position of the pivot along the axis of the same hinge.
  • the desired position of the pivot is obtained by revolving the same pivot inside the relevant screw­threaded seat destined to be fastened to the doorpost.
  • the rotation of the pivot when the hinge is mounted in its operative position is carried out by acting on the first, hexagonal end of an idle spindle, coaxial with the same pivot, and provided with a second end having a blade shape, which engages a slot provided in the pivot.
  • blocking means constituted by a blocking grub screw, constrain the pivot, so as to prevent it from rotating around the axis of the hinge when the door is opened and closed.
  • the adjustable hinge contrarily to the non-­adjustable hinge, while is capable of obviating the early wear of the bearing due to the overcharges applied to said bearing due to settlings of the doorposts, is not anyway capable of obviating the wear deriving from missed lubrication and to the penetration of foreign bodies inside the bearing.
  • the bearing acts as a coupling interposed between the female element of the hinge and the ring-shaped surface associated with the pivot of the male element, applying to this latter such a high twisting tor-que, as to easily exceed the strength of the pivot blocking means, in particular the above mentioned grub screw, which gets broken during the rotation of the hinge.
  • a type of adjustable hinge which houses the friction undergoing means inside the female element.
  • Such a hinge is provided with a ball placed atop the pivot, which may or may not be adjustable along the axis of the same hinge, and resting against the bottom surface of the bore the female element is provided with.
  • the ball can be: - realized with a rather high diameter, because said diameter is no longer dictated by pressing problems relating to overall dimensions; - sheltered, because it is housed on the bottom of the bore of the female element.
  • hinges have resulted to be not free from drawbacks due to the excessive wear the top surfaces of the pivot, the bottom surface of the female element, and the same ball are subjected to.
  • the purpose of the present invention consists in providing a hinge capable of obviating all the drawbacks which are due to the above types of hinges, wherein the elements under relative motion stressed by the load are: - of a relatively large diameter, so as to validly counteract the stresses due to the weight of the door, even if increased due to phenomena of settling of the doorposts; - sheltered, and therefore well-lubricated over time, by a tight seal, so as to enable the hinge to be used also outdoor and/or in corrosive environments; - submitted to rolling friction, and not to sliding friction.
  • a hinge in particular for armour-clad doors or the like, comprising a male element and a female element, respectively formed by a cylindrical pivot provided with a top plane, and a cylindrical bore provided with a bottom plane, with said pivot and said bore revolving the one inside the other according to a common revolution axis which constitutes the revolution axis of the hinge, characterized in that the top plane of the pivot and the bottom plane of the bore interact along ring-shaped areas equipped with low-­friction-coefficient elements.
  • the hinge for armour-clad doors and the like comprises a male element 2 and a female element 3.
  • the male element 2 is formed by a cylindrical base 4, and a pivot 5, also cylindrical, and constituting one single body with the same base, with which it joins defining a ring-shaped plane 6.
  • the cylindrical base 4 is provided with a flange 7 which constitutes a means for it to be fastened to a door (not shown in the figures).
  • the pivot 5 is provided with a top plane 8 provided with a first ring-shaped area 16, wherein a first race 9 is provided, which is engaged by rolling elements, e.g., balls 10, running along said race 9 with low values of friction coefficient.
  • the female element 3 is provided as well with a cylindrical base 11 provided with a flange 12, identical to the flange the cylindrical base 4 of the male element 2 is provided with, and destined to be fastened to the doorpost (not shown in the figures).
  • Said female element 3 is associated with a cylindrical bore 13 ending with a bottom plane 14, also provided with a second ring-shaped area 17 wherein a second ring-shaped race 15 is provided, which is identical to race 9, and is destined as well to be occupied by the balls 10.
  • either, of both, of ring-shaped areas 16 and 17 are constituted by removable elements bearing the races 9 and 15, which, in this way, can be more easily submitted to the hardening thermal treatments, or replaced when their wear degree so requires.
  • the removable elements of the ring-shaped areas 16 and 17, and the balls 10 can be replaced by at least a washer 24 made from an anti-­friction material, and acting as a bushing.
  • the hinge In order to secure a sufficient and constant lubrication of the balls or of the bushing, the hinge must be installed in such a way that the female element directs upwards its concavity, so as to also act as a sump for the lubricant of the hinge.
  • the hinge is completed by a tight-sealing gasket 22 placed between the edge 23 of the bore 13, and the ring-­shaped plane 6 of the pivot 5, which simultaneously prevents the lubricant from escaping, and foreign bodies from entering the hinge.
  • a tight-sealing gasket 22 placed between the edge 23 of the bore 13, and the ring-­shaped plane 6 of the pivot 5, which simultaneously prevents the lubricant from escaping, and foreign bodies from entering the hinge.
  • the hinge 1 is endowed with the possibility of stably adjusting the position along the revolution axis A-A of the same hinge, of the second ring-shaped area by means of screw/counterscrew means.
  • Such screw/counterscrew means comprise a nut screw 18, coaxial with axis A-A and provided inside the cylindrical base 11 of the female element 3, which is enganged by a first screw 19 totally contained inside the same nut screw, and provided, at a first endsthereof, with a drive element 20 of embedded-octagon configuration.
  • the second sliding race 15 is provided, on which the balls 10 run.
  • a second screw 21 is housed, whose structure is at all similar to that of the first screw, and acts on said first screw so as to block it inside the same nut screw.
  • the position of the race 15 can be adjusted along the axis A-A, thus enabling the hinge to compensate for possible settlings of the doorpost or of the door on which it is installed, making is possible the loads to be equally subdivided on each hinge of the same door.
