DETAILED DESCRIPTION OF THE INVENTION

(8) Referring to FIGS. 1 to 3, a first embodiment of toilet seat hinge according to the disclosure includes a hinge base 10 comprising a fixing part 11 and a cover 12, a threaded fixing bolt 13, and a pillar 14. The fixing part 11 is fixed to the upper surface of a toilet pan 15 by an adhesive, preferably a very high bond (VHB) double sided tape 16, which adheres on one side to a contact surface 17 of the fixing part 11, and on the other side to the toilet pan 15. A protective paper covering 16a is provided to cover the VHB tape on that surface that is to bond to the pan, prior to installation of the hinge.

(9) At installation with the fixing part 11 secured in position, the cover 12 is located over the fixing part and is secured in position by the threaded fixing bolt 13. In the conventional manner, the bolt 13 is engaged at one end in the cover 12, is passed through locating holes (not shown) in the pan 15, and is secured on the underside of the pan using a nut 18 and washer 19. Tightening of the nut 18 clamps the contact surface 17, with attached VHB tape 16, against the toilet pan and thus ensures that a very secure connection is achieved between the hinge and the pan.

(10) In the embodiment shown in FIG. 1, the hinge is what is referred to in the trade as a bottom-fixing hinge. In the embodiment shown in FIGS. 4 & 5, the hinge is a top-fixing hinge. The disclosure described herein is applicable to both forms of hinge.

(11) A characterising feature of the disclosure is that the hinge can be moved freely and located in the desired position relative to the pan, and then secured in position on the pan, without the need for any trial assembly. To this end a spacing facility is provided that is configured to space the contact surface 17, and the VHB tape (with cover paper 16a removed therefrom) from the pan while the hinge base is positioned in the correct location. When in the correct location, the hinge base is displaced toward the pan, and the spacing facility is displaced or deformed until the VHB tape comes into contact with the pan. The displacing force applied to the hinge base may be applied manually and/or may be effected by tightening the nut 18.

(12) Referring to the embodiment shown in FIGS. 1 to 3, the spacing facility is formed as an integral part of the hinge base and projects from the periphery of the contact surface 17. As can be seen most clearly in FIG. 2, three projections 20 are spaced around the periphery of the contact surface 17 and project outwardly from the plane of the surface. The projections are preferably equi-spaced around the periphery to provide the necessary support function, and each has a vee-shaped central formation 21 to assist deformation and/or fracturing. Underlying each of the projections is a recess 22.

(13) As can be seen in FIGS. 3a to 3c, when the hinge base is first located against the toilet pan 15, and with the protective covering 16a removed, the projections 20 maintain the under-surface of the VHB tape clear of the pan. As can be seen in FIG. 3c, with only the projections 20 contacting the pan, the fixing part 11 may be displaced over the pan surface until the final fixing position is established. Thereafter, as shown in FIG. 3c, a downward displacing force is applied to the fixing part 11 which causes the projections to distort and possibly to fracture. The distorted or fractured remnants of the protections are then received in the recesses 22. It will be appreciated that, as the projections distort or fracture, the VHB tape contacts the pan and bonds the fixing part 11 to the pan 15.

(14) Referring now to FIGS. 4 and 5, parts of a second embodiment of hinge are shown, this embodiment including a hinge base 30, a hinge connector 31 projecting upwardly from the base, a fixing bolt 32, and a spacer 33. A disc 34 of VHB tape is fixed to the underside of the base 30 and the underside of this disc is maintained out of contact with the surface of the toilet pan, while the base is positioned in the desired location relative to the pan.

(15) In this particular embodiment the spacer comprises a ring having an inner annular surface 35 that engages a downward spigot 36 forming part of the base 30. The spigot 36 may be a firm frictional fit within the spacer 33 or the surfaces 35 and 36 may be formed with complimentary projection and socket. Whatever the case, the inter-engagement of base and spacer is configured to ensure the VHB tape is held clear of the pan during positioning of the base 30 but, once the base is correctly positioned, the application of manual pressure, or pressure applied by tightening the fixing bolt 32, will overcome any resistance between the base 30 and the spacer 33, causing the spigot 36 to slide within the spacer until the VHB tape contacts and bonds to the surface of the pan. FIG. 5a shows the base 30 in the raised position relative to the pan 15 while FIG. 5b shows the base 30 displaced so that the VHB tape is bonded to the pan.

(16) Referring now to FIGS. 6a and 6b, parts of a third embodiment of the disclosure are shown comprising a hinge base 40 for connection to a surface 15 of a toilet pan using a disc 41 of VHB tape. During positioning of the base 40 relative to the pan 15 the base is maintained clear of the pan by a spacer 42 which comprises a base plate 43 having a number of spikes 44 projecting downwardly therefrom. The base 40 and VHB tape 41 are formed with holes 45 in positions that correspond to the positions of spikes 44 and thus the spikes can be engaged through the holes 45 to engage the surface 15 of the pan. It will be seen that the length of the spikes 44 is greater than the thickness of the base 40 and thus with the spacer 42 fully engaged with the in the desired location, it may be displaced downwardly whereupon the spikes 44 disengage from holes 45 and the VHB disc can engage and bond to the surface 15 as shown in FIG. 6b. The spacer 42 can then be removed completely.

(17) Any suitable means can be provided to maintain the base 40 in the upward position shown in FIG. 6a, during positioning of the base 40. For example the spikes 44 and holes 45 may be configured to provide friction between the two when in the position shown in FIG. 6a. Other means such as engaging projections and recesses could be used and a further option would be to use a relatively low bond double-sided adhesive tape between the under side of plate 43 and the upper side of the base 40.

(18) Whilst the embodiments described herein conveniently incorporate an adhesive in the form of a VHB tape, it will be appreciated that other forms of adhesive including liquids and pastes could be used without departing from the scope of the disclosure.

(19) Referring back to FIG. 1, in another aspect the disclosure provides a novel and useful means of mounting the hinge pillar 14, to the hinge base and, in particular, to the cover 12.

(20) When installing toilet seat hinges, the positions of hinge fixings 11, covers 12 and pillars 14 must be manipulated to ensure that the seat is correctly located along fore and aft, and lateral, axes. Generally, changing the position of one component affects the positions of the others and so a trial installation is undertaken in which the components are loosely interconnected, the correct positions are established and noted, and the components then disassembled, tightened and fixed back in the established positions. The present disclosure proposes methods and apparatus which eliminate the need for pre-assembly and allow correct positioning of components, and secure fixing, from the outset.

(21) In the foregoing we have described a method for correct positioning and fixing of the hinge base relative to the pan. Further adjustment is required between the pillar 14 and the cover 12. Previously, with the pillar directly attached to cover 12 using a fixing screw 25 any rotation of the pillar relative to the cover, to establish correct positioning, would loosen the fixing screw 25. Thus, once the correct positions had been established, the cover 12 would have to be removed and the screw 25 re-tightened as part of final assembly. This problem is addressed in a further aspect of the disclosure by mounting pillar 14 on an intermediate mount 26 using fixing screw 25. The intermediate mount 25 is configured to be a firm rotating fit within the cover 12 and thus the pivotal position of the pillar 14 relative to the cover can be established without any loosening of the connection between the pillar and the cover.

(22) It will thus be appreciated that the disclosure, as least in the case of the various embodiments described, allow toilet seat hinge components to be positioned and fixed to a toilet pan effectively and without significant, or possibly any, trial assembly.

(23) The above disclosure is described with reference to some embodiments. However, it is realized that other embodiments may be provided without departing from the scope of the disclosure.
