Definitions

  • the present invention relates to a bushing assembly for hinges and a hinge provided with such a bushing assembly, which can be used, for example, for doors or windows or for furniture doors.
  • Hinges of the type shown in Figure 1 are currently known to be used to articulate doors and windows in building, frames, the hinge being generically referred to as 1.
  • the hinge 1 comprises a pin 3, a male wing 5, into which the pin 3 is forcibly inserted or otherwise locked with an essentially irreversible coupling, and a female wing 7, which is designed to fit over the pin 3 so that it can rotate about it.
  • the pin 3 and male 5 and female 7 wings are usually made of metal.
  • the "male wing” of a hinge means a wing that is fixed integrally to the hinge pin, preventing relative rotation between the wing and the pin;
  • the "female wing” means a wing that is not fixed integrally to the hinge pin so that it can at least rotate about such pin. It is clear that this indication cannot in any way constitute a limitation of the scope of protection of the present invention.
  • a known anti-wear bushing 9 has a hollow tubular body 90 and a flange 92 that extends around either end of the tubular body 90 projecting radially therefrom.
  • a wear-resistant bushing 9 is threaded onto the pin 3 and inserted into a suitable female seat (not shown) obtained in the female wing 7, allowing the female wing 7 to rotate about the pin 3, avoiding direct metal-on-metal sliding during such rotation.
  • This second solution although effective in solving the above-mentioned problem of metal-on-plastic rubbing of the first known solution, eliminating, or at least considerably limiting, the wear on the bushings 9, increases the axial distance between the male wings 5 and female wings 7, so that the flanges 92 constitute a higher, and therefore visible, element, with an inevitable impact on the aesthetics of the hinge.
  • an object of the present invention is to provide a bushing assembly and hinge that can address and solve the above-mentioned problems typical of prior art hinges, both with regard to wear on their wear-resistant bushings and with regard to the aesthetic appearance of the hinge itself.
  • Figures 2-6 relate to a bushing assembly according to an embodiment of the present invention, and to a hinge provided with said bushing assembly.
  • Such a hinge indicated by the overall reference 100, comprises a pin 103, a first male wing 105 and a second male wing 105', into which the pin 103 can be inserted, and at least one female wing 107 arranged to fit onto the pin 103 so as to be able to rotate about it.
  • the hinge 100 may comprise, for example, a single male wing 105 and/or two or more female wings 107.
  • the pin 103 and male wings 105, 105' and female wings 107 can be made, for example, of steel, aluminium or other suitable metal materials.
  • the hinge 100 comprises one or more bushing assemblies 109, each of which in turn comprises a bushing 190 and a ring 192, wherein both the bushing 190 and the ring 192 are preferably made of a suitable plastic material.
  • the bushing 190 and ring 192 can be made of the same or different plastic material.
  • the bushing 190 has a substantially tubular shape that is hollow and open at opposite ends, with a first open end 190' delimited by a first end edge 190".
  • the ring 192 substantially has a shape corresponding to the first open end 190' of said bushing 190 in order to be coupled with the first open end 190' of the bushing 190 by resting against at least part of the first end edge 190", and more preferably against the entire end edge 190", also being able to protrude radially beyond it ( Figure 5 ).
  • the bushing 190 also has a second end edge 190′′′ at the second open end thereof ( Figures 3 and 4 ).
  • the inner cavity 194 of the bushing 190 has a longitudinal axis AR, which preferably coincides with the axis of mutual rotation between the male wings 105 and female wings 107 of the hinge 100 and/or with the longitudinal axis of the pin 103.
  • Said bushing 190 and said ring 192 have means for being reversibly and rotatably attached to each other.
  • the bushing 190 and the ring 192 in the illustrated embodiment provide for a snap-fit coupling system, consisting of one or more axial coupling projections 198, 199.
  • the ring 192 may be provided with one or more first axial coupling projections 199, for example of two, three, four, five or more projections 199.
  • the bushing 190 provides for an equal number of second axial projections 198.
  • Each first axial coupling projection 199 can be in the form of, for example, a tongue or a protruding, relatively elastic and deformable rib. Each first axial coupling projection 199 will have a shape complementary to that of the second axial coupling projections 198.
  • the female wing 107 in its rotation, drags the bushing 190, inserted therein so as to come into contact with the pin 103.
  • the bushing 190 thus rotates with respect to the ring 192, which is substantially integral with the top of the male wing 105, ensuring plastic-on-plastic sliding of the former on the latter, rather than plastic-on-metal when the hinge 100 rotates.
