Definitions

  • the present invention relates to a coupling hinge, in particular a coupling hinge for seats and covers of hygienic bowl.
  • seats and covers for closing hygienic bowl are hinged to the hygienic bowl by hinges that allow rotating the seat or cover relative to the bowl from a horizontal closed position, resting on a support surface of the bowl, to a substantially vertical open position, wherein the seat or cover forms an angle not smaller than 90 degrees with said support surface.
  • hinges which envisage means for damping the movement of rotation of the seat or cover, so as to cushion the movement of fall back of the cover or seat on the bowl.
  • Such prior art solutions envisage the use of hinges that comprise viscous liquids arranged inside the hinges for obtaining a damping effect.
  • the problem of the present invention is to provide a hinge which should solve the disadvantages mentioned with reference to the prior art.
  • figure 1 shows a side view of a hinge according to an embodiment of the present invention
  • figure 2 shows a section view of the hinge of figure 1 , along the section line II-II of figure 1 ;
  • figure 3 shows an exploded perspective view of the hinge of figure 1 ;
  • figure 4 shows a section view of the hinge of figure 1 , along the section line IV-IV of figure 1 , in a first operating position
  • figure 5 shows a section view of the hinge of figure 1 , along the section line IV-IV of figure 1 , in a second operating position;
  • figure 6 shows an application of the hinge of figure 1 to a hygienic bowl in a first operating position
  • figure 7 shows an application of the hinge of figure 1 to a hygienic bowl in a second operating position.
  • reference numeral 4 generically denotes a coupling hinge for a hygienic bowl 8, suitable for obtaining a rotary coupling along a first axis of rotation (X-X) between a hygienic bowl 8 and a seat 12 or cover 14 associated thereto.
  • cover 14 or seat 12 can rotate from a closed position wherein they abut against a support surface 16 of the hygienic bowl 8 to an open position wherein said seat or cover form an angle not smaller than 90 degrees with support surface 16.
  • hinge 4 comprises a first coupling element 20, suitable for being integrally constrained in rotation to sad seat or cover 12, 14 so as to rotate with the seat or cover, and a second coupling element 24 suitable for being integrally constrained to said hygienic bowl 8 so as to not rotate relative to said first axis of rotation X-X.
  • hinge 4 comprises a guiding element 30 fixed relative to said first axis of rotation X-X, and having a guiding portion 34 defining at least one cam profile 38.
  • the first coupling element 20 comprises a cup portion 42 at least partly fit on said guiding portion 34 and comprising contrast means 46 suitable for abutting against said guiding cam profile 38 and for following said profile in the movement of rotation of the first coupling element 20, so as to oppose the rotation of said first coupling element 20.
  • the cup portion 42 comprises at least one seat 48 suitable for turnably seating said contrast means 46 relative to a second axis of rotation Y-Y, parallel to said first axis of rotation X-X.
  • the contrast means may comprise at least one roll 50 turnably seated in said seat 48 so as to protrude from said seat 48 radially, that is, relative to a direction incident with the second axis of rotation Y-Y and contained in a plane perpendicular to the second axis of rotation Y-Y, so as to abut against said guiding cam profile 38.
  • the cup portion 42 comprises three seats 48 and three corresponding rolls 50 arranged angularly at a pitch relative to said first axis of rotation; in other words, preferably the rolls and the respective seats are arranged at 120 degree relative to said first axis of rotation X-X.
  • the first coupling element 20 comprises, opposite said cup portion 42, a coupling head 54 suitable for being integrally connected in rotation to said seat or cover 12, 14.
  • said coupling head 54 may be inserted in a pin 55 for connecting the seat or cover 12, 14 to bowl 8.
  • the coupling head 54 comprises at least one levelling 56 suitable for favouring the connection in rotation between the first coupling element 20 and the seat or cover 12, 14.
  • the guiding portion 34 comprises at least one cam profile 38, said profile 38 having a curvilinear pattern from a portion of maximum radial distance 60 relative to the first axis of rotation X-X to a portion of minimum radial distance 64 from the first axis of rotation X-X.
  • the portion of maximum radial distance 60 in an assembled configuration wherein the cup portion 42 is at least partly fit on said guiding portion 34, touches an inside diameter of the cup portion 42.
  • the cam profile 38 comprises a rise 68 that is jointed to the portion of maximum radial distance 64 of an adjacent profile 38; said rise 68 determines a stop position for said contrast means 46.
  • the guiding element 30 preferably comprises a shoulder 72, axially opposite the guiding portion 34, so as to stop the axial introduction of the cup portion 42 on the guiding portion 34.
  • shoulder 72 is coaxial with said guiding portion 34.
  • the guiding element 30 comprises, opposite shoulder 72 relative to the guiding portion 34, a pin 76 suitable for being at least partly seated in a cavity 75 of said first coupling element 20, so as to coaxially centre the guiding element 30 relative to the first coupling element 20.
  • said hinge 4 comprises a collar 80, preferably elastic, suitable for being fitted coaxially to the first axis of rotation X-X, on the guiding portion 34, so as to arrange in contact with said contrast means 46, the contrast elements 46 being arranged between the guiding element 30 and collar 80.
  • collar 80 has such axial extension as to be fitted on both the guiding portion 34 and shoulder 72.
  • collar 80 is fitted with interference on the guiding portion 34 and on shoulder 72.
  • the elastic collar 80 has a radial thickness at least equal to the difference of radial thickness between the contrast means 46 and the cup portion 42.
  • the elastic collar 80 is of polymeric material.
  • the second coupling element comprises a coating 84, suitable for coating said first coupling element 20.
  • the coating preferably has such inside diameter as to be fitted with interference on said collar 80 so as to lock in rotation the guiding element 30 relative to the first axis of rotation X-X.
  • coating 84 comprises a coupling hole 88 suitable for allowing the passage of a pin 90 for obtaining a mechanical connection between a fixing portion of said hygienic bowl and said hinge 4.
  • said guiding element 30 comprises a fixing hole 92 suitable for allowing the introduction and locking of said pin 90, so as to lock in rotation the guiding element 30 relative to the hygienic bowl 8.
  • the roll position in order to carry out correct assembly, the roll position must be calibrated relative to the guiding portion so as to ensure correct stops of the opening and closing movement of the seat or cover relative to the bowl.
  • the hinge is mounted with the cover in open position, that is, in a position wherein the cover forms an angle of at least 90 degrees with the bowl, and preferably an angle comprised between 90 and 120 degrees, the rolls must be substantially positioned at the recesses of the guiding portion ( figure 4 ).
  • the cam profile 38 may comprise a portion that exerts no friction or interference action with the contrast means 46 by a first portion of the travel of the seat or cover and then it exerts a contrast action only in the last travel portion.
  • the profile may have such radial distance from the first axis of rotation as to prevent contact between the contrast means and profile 38 of the guiding portion 34.
  • the hinge according to the present invention allows overcoming the disadvantages of the hinges of the prior art.
  • the hinge according to the present invention is simple and inexpensive to manufacture.
  • the hinge of the present invention is not subject to any loss of inside liquids since it is provided with no hydraulic damping system of the movement of rotation.
  • the hinge of the present invention exhibits limited overall dimensions and may be easily applied also to existing hygienic bowl, without interfering with the bowl, the seat or the cover in any way.
  • the damping determined by friction by the present hinge allows the movement of fall back of the seat or cover to be perfectly controlled preventing any violent collision with the hygienic bowl.
