Definitions

  • the present invention relates to a toilet hinge arrangement comprising a toilet cover assembly for fastening to a toilet bowl.
  • a further aspect is that in many cases it is desirable to be able to easily remove the toilet cover assembly and for this reason a number of systems exist where the hinge mechanism may easily be manipulated in order to release the hinge mechanism from the toilet bowl in order to remove the toilet cover assembly.
  • toilet cover assemblies tend to be very closely assembled in the hinge arrangements in order to provide a stable and controlled movement of the seat/cover relative to the toilet bowl in order to give the user a feeling of quality.
  • the invention addresses this by providing a toilet hinge arrangement according to claim 1.
  • the adaptor ring will centrally have an opening adapted to accommodate the shaft of the damper in such a manner that the rotational forces from the cover/seat will be transferred to the damper shaft if the adaptor ring is engaging the engagement surfaces on the seat/cover as explained above.
  • the damper may be suitable for use with a number of various seats or covers and at the same time the apertures and cavities provided in the ear lugs of the seat/cover may be formed substantially freely in that the catch ring and/or adaptor ring shall be shaped such that they will work as interface between the damper shaft and the interior surfaces and engagement surfaces of the ear lugs.
  • the catch cavities have a substantially partly spiral surface initiating at the inner surface of the through-going aperture with increased distance to the rotation axis said substantially spiral surface terminating in a further engagement side arranged radially relative to the rotation axis, such that as the catch ring is inserted into the through-going aperture the spring action catches will expand into the catch cavities and the terminal ends of the spring catches will engage the engagement side.
  • At least two catch cavities are provided, and where the substantially partly spiral surfaces are arranged with opposite orientation.
  • the feature of having the spiral surfaces in opposite directions/orientation is advantageous in that the spring action catches when engaging the engagement sides of the cavities will engage and thereby block rotation in both directions of the ear lug relative to the catch ring.
  • the adaptor ring has two parallel engagement surfaces arranged symmetrically around the axis of rotation, and where two corresponding engagement surfaces are provided on the inner side of the cavity of the outermost ear lug.
  • the engagement means for engaging fastening means on the toilet bowl, provided in the opposite end of the damper comprises a radial bore adapted in use to receive a mounting pin mounted on the toilet bowl, where said pin adjacent a distal end is provided with at least one circumferential groove, and where the damper in the end opposite from the end from where the damper shaft extends is provided with a slit perpendicular to the axis of the bore, such that when the pin is inserted in the bore, the circumferential groove will be positioned superposed the slit, such that a lock tab may be inserted in the slit, and engaging at least a part of said circumferential groove, thereby retaining the pin relative to the damper.
  • damper shaft and the catch ring and/or adaptor ring are removably fitted on the damper shaft by a snap feature.
  • This snap feature may for example be in the shape of grooves or indentations provided in the shaft of the damper and corresponding protrusions or ridges provided in the catch ring and/or adaptor ring.
  • the catch ring, and the adapter ring and the resilient member are one integrated unit.
  • the catch ring comprises a body section and a separate resilient member, where the separate resilient member is fitted in tracks in the body section, such that a part of the separate resilient member extends past the periphery of the body section, in use extending into catch cavities in an ear lug.
  • figure 1 is illustrated the rear side of a part of a seat 10 and a cover 12 where the rear part of the seat and cover respectively is provided with ear lugs 11, 13.
  • the ear lugs 11, 13 are provided with a cavity 14, 15.
  • the cavity is suitable to accommodate a damper assembly 20 as will be explained with reference to figures 3a-3b .
  • the damper assembly 20 is illustrated in an assembled situation in figure 3a and in an exploded view as illustrated in figure 3b .
  • the damper assembly comprises five main parts.
  • the damper 22 is provided with a damper shaft 24 which extends from one end of the damper 22.
  • the damper shaft 24 may rotate around a central axis 100 illustrated by a dashed line.
  • a toilet cover assembly will be provided with two hinge arrangements and as such the central axis 100 will pass through the rotation axis of both hinges in order to create a coordinated pivotable movement of the toilet cover assembly, i.e. the toilet seat and the toilet seat cover.
  • damper 22 In the opposite end of the damper shaft 24 the damper 22 is provided with engagement means 26 such that the damper may be fastened to a corresponding fastening means extending from the toilet bowl.
  • This fastening concept will be explained with reference to figure 4, 5 and 6 .
  • a catch ring 28 and an adaptor ring 30 On the damper shaft 24 is arranged a catch ring 28 and an adaptor ring 30.
  • the seat may now only be rotated by also rotating the damper shaft 24 such that the dampening action provided by the damper 22 is transferred to the seat.
  • the adaptor ring 30 which is also mounted on the damper shaft 24 is not provided with engagement rings such that the cover may pivot freely relative to the adaptor ring.
  • ridges 36, 38 may be provided in the catch ring and the adaptor ring respectively, and corresponding grooves 40, 42 are provided in the damper shaft 24.
  • the engagement means 26 are as will be explained with reference to figures 4, 5 and 6 suitable to engage and lock onto a hinge pin 50.
  • the hinge pin 50 has a diameter such that it may be inserted into the aperture 26' provided in the damper 22.
  • the hinge pin 50 has a number of grooves 51, 52, 53 which serve various purposes.
  • the lowermost groove 53 accommodates a stabilizing O-ring such that as the hinge pin 50 is inserted in the aperture 26', the stabilizing O-ring 53' having an outer diameter slightly larger than the diameter of the hinge pin will engage the walls of the aperture 26' thereby creating a stable fit between the hinge pin and the damper 22.
  • a friction spring which as the hinge pin 50 is inserted in the aperture 26' will be slightly compressed thereby offering a slight resistance, but once the hinge pin is completely inserted into the damper aperture 26' the friction spring will help to retain the hinge pin in a stabilized manner relative to the aperture 26'.
  • the groove 51 is a locking groove such that when the hinge pin 50 is completely inserted into the aperture 26' as illustrated in figure 5 a lock tab 56 may be inserted radially relative to the hinge pin in a direction corresponding to the central axis 100 such that the lock tab 56 will engage the locking groove thereby fixing the damper relative to the hinge pin 50.
  • the damper 22 is mounted to the hinge pin 50 in a firm and stable manner.
  • the hinge pin 50 is fully inserted into the aperture 26' and the stabilizing O-ring 53' engages the sides of the aperture and the friction spring accommodated in the groove 52 furthermore stabilizes and assists in holding the hinge pin relative to the aperture 26'.
  • the lock tab 56 is fully inserted and engaging the locking groove 51 such that the damper 22 is held by the hinge pin 50.
  • the hinge pin is by its own means mounted to the toilet bowl and in this manner the toilet cover assembly is fixed in a releasable manner due to the releasable action of the lock tab to the toilet bowl.
  • FIGS 2a and 2b is illustrated how the catch ring 28 co-operates with an ear lug 11, 13.
  • the ear lug 11 one or more, in this embodiment two catch cavities 34 are provided.
  • Each catch cavity has a spirally curved surface 41 connecting with an engagement side 43.
  • the resilient spring action catches 32 provided on the catch ring will when assembled as illustrated in fig 2b expand into the catch cavities 34, thereby coupling the ear lugs 11, 13 to the catch ring 28.
  • the resilient member 35 may be seen centrally in the assembly.
  • figure 9 is illustrated a cross section of part of a left-hand and a right-hand damper assembly where the damper shaft 24 is provided with both a catch ring 28 and an adaptor ring 30.
  • FIG 10 an isometric schematic illustration of the left-hand side damper assembly illustrated in figure 9 is illustrated in a situation where it is ready to be mounted on the ear lugs 11, 13 of same side of the cover and the seat respectively.
  • the through-going aperture 14 provided in the ear lug 11 is provided with catch cavities 34.
  • the catch ring 28 will therefore when inserted in the through-going aperture 14 be expanded such that the spring action catches 32 will expand into the catch cavities 34 thereby locking the ear lug 11 relative to the catch ring 28 whereby any rotation of the ear lug 11 due to the engagement of the catch ring 28 by means of the spring action catch's 32 engagement with the catch cavities 34 transfer any rotational force to the damper 22.
  • the ear lug 13 is provided with a cavity which in a cross-section has a circular cross-section such that the engagement surfaces 31 of the adapter ring 30 are not locked relative to the ear lug 13 such that the ear lug 13 may rotate freely with respect to the adaptor ring 30. Therefore, in this embodiment the left-hand side as illustrated in figure 10 will transfer rotational forces from the seat's ear lug 11 to the damper 22 whereby the left-hand side cover ear lug 13 is not influenced by the damper and therefore may move freely with respect to the damper mounted in the left-hand side of the toilet seat arrangement as illustrated in figure 9 .
  • the adaptor ring 30 will fit inside a cavity having parallel sides 31', 33' such that the engagement surfaces 31, 33 will engage and be held by corresponding surfaces 31', 33' provided inside the cavity provided in the ear lug 13'.
  • the catch ring 28 is comprises a body section 28' provided with a track or groove 55 in a peripheral side face.
  • a separate resilient member 58 fits inside the track/groove 55, such that in use the resilient member 58 being provided with a bend 57, where said bend 57 engages one or more catch cavities provided in the ear lug 11, 13.
  • fig. 13 a similar embodiment is depicted where the separate resilient member 58' is a clip-structure, but has the same function as described above with respect to fig. 12a, fig. 12b and fig. 12c .
