Description
- This invention relates to an attachment mechanism for a toilet seat/lid arrangement and a method of using the same.
- Conventionally, a toilet seat and/or toilet lid are attached to a toilet pan using one or more bolts that are inserted through apertures defined on an upper surface of the toilet pan adjacent a rear edge or cistern thereof. One or more washers and nuts are used to secure the one or more bolts to the toilet pan on a lower surface of the toilet pan. It is often the case that a decorative location disk is provided on the upper surface of the toilet pan for association with each aperture. The decorative location disk includes an aperture therethough and a user typically has to align the bolt with the decorative location disk and the aperture on the toilet pan prior to securing the bolt with the washer and nut from the underside surface of the toilet pan. This process can be fiddly and time consuming for a user to undertake. It can also be difficult for a user to access the underside surface of the toilet pan, particularly if the toilet is located in a confined space. In addition, since there are a number of components used in the attachment of the toilet seat/lid to the toilet pan, and each of these components may have screw threads or non-planar surfaces and the like associated with the same, these components can be difficult to keep clean. This is undesirable for a toilet where maintenance of hygiene is important.
- Document
WO 90/15565 A1 Further document DE 20 2013 102982 U1 discloses an equipment series characterized in that an instant mounting fastener is provided and the fastener and can be matched to and used for all items of equipment, e.g. in the bathroom, kitchen, WC etc. whereby the fastener could comprise a suction cup and the suction cup could build up the vacuum effect via an integrated pump. - It is therefore an aim of the present invention as defined in claim 1, to provide an attachment mechanism which overcomes the abovementioned problems.
- The invention further comprises a method claim 8 defining steps for attaching a toilet seat to a toilet pan. In the appended claims preferred embodiments of the invention are defined.
- According to a first aspect of the present invention there is provided an attachment mechanism for attaching a toilet seat to a toilet pan, the attachment mechanism comprising: a body portion having engagement means for engaging part of a toilet seat; attachment means for attaching the body portion to the toilet pan, wherein the attachment means comprises a suction cup having a suction cavity; and an actuation mechanism to allow the suction cup to be moved between a first engaged position and a second disengaged position; wherein the actuation mechanism comprises a pump and the pump has a conduit that connects with the suction cup to allow fluid to be removed from the suction cavity of the suction cup; wherein the actuation mechanism is provided in or associated with the engagement means of the attachment mechanism, such the movement of the engagement means actuates movement of the actuation mechanism.
- Thus, the present invention uses vacuum/suction means for attaching a toilet seat to a toilet pan in use. This has the advantage that no apertures are required to be formed in the toilet pan for the location of toilet seat/lid attachment bolts as is conventionally required. This simplifies the tooling required for manufacturing the toilet pan and improves the aesthetic appearance of the resulting toilet. The toilet seat can be fitted and/or removed by a user entirely from an upper surface of the toilet pan and so the problem associated with the prior art of gaining access to the underside surface of the toilet pan for securing/releasing attachment of the toilet seat is removed. The process of fitting and/or removing the toilet seat with respect to the toilet pan is significantly simplified, no special tools or user skill is required, and the time for undertaking the fitting/removing process is significantly reduced. There are no, or at least a reduced number, of exposed non-planar attachment parts to be kept clean in use, thereby making the resulting toilet arrangement easier to clean. In addition, the toilet seat can be positioned wherever the user wishes on an upper surface of the toilet pan and the positioning is not limited to the location of toilet seat attachment apertures, as is conventionally the case with prior art toilets. The attachment mechanism therefore offers a universal fit, irrespective of the design, shape and/or dimensions of the toilet pan and/or toilet seat.

Figure 8 shows a perspective view of a toilet seat and lid arrangement including the attachment mechanism offigures 4a-4e . - Referring firstly to
figures 1a and 1b , there is illustrated a toiletseat attachment mechanism 2 comprising anelongate body portion 4 having atop surface 6, abase surface 8,end walls rear side walls - Engagement means 18 are provided to allow engagement of a toilet seat (not shown) to the same in use. The engagement means can take any suitable form to allow a toilet seat to be pivotably or hingedly connected to the
attachment mechanism 2. - Vacuum or suction means in the form of two
suction cups base surface 8adjacent end walls inner surface 24 of thesuction cups mechanism 2 is to be attached to in use is curved, as shown bydotted line 26. Thesuction cups - User actuation means 28 are associated with each
suction cup suction cups inner surface 24 is moved towards the surface to which themechanism 2 is to be attached to in use, so that theinner surface 24 forms a relatively planar or substantially horizontal position; and a disengaged position, wherein theinner surface 24 is moved away from the surface to which themechanism 2 has been attached to and forms a relatively curved or non-planar position. - The user actuation means 28 includes an
operating lever 30 which is pivotably connected to one end of an actuatingarm 32 at apivot point 34. Resilient biasing means in the form of aspring 36 is associated with each actuatingarm 32. Theother end 38 of the actuatingarm 32 is attached centrally to the outer surface of thesuction cup -

The user actuation means 28 are typically in a disengaged position. In the disengaged position, a longitudinal axis of theoperating lever 30 is vertical or substantially vertical and/or is perpendicular or substantially perpendicular to thetop surface 6 of the attachmentmechanism body portion 4. Theinner surface 24 of thesuction cups inner surface 24 of the cup and thetoilet pan surface 40 on which the attachment mechanism is located. - With the attachment mechanism in the user selected required position, a user grips each
operating lever 30 and pivots thelevers 30 outwardly (or inwardly) of each other towards thetop surface 6 of the attachmentmechanism body portion 4. This brings theoperating levers 30 to an engaged position, wherein a longitudinal axis of the levers is substantially parallel, parallel, horizontal or substantially horizontal with respect to thetop surface 6. The user has to apply sufficient force in moving theoperating lever 30 from the disengaged position to the engaged position to overcome the biasing force ofspring 36. During this movement, theinner surface 24 of thesuction cup upper surface 40 oftoilet pan 42. This movement forces the air contained in the cavity 39 outwardly of the peripheral rim of the suction cup to form a partial vacuum, such that the air pressure on the outer wall of thesuction cup attachment mechanism 2 andtoilet seat 44, to theupper surface 40 of thetoilet pan 42. - If a user requires removal of the toilet seat, such as for cleaning purposes, replacement and/or repair, a user simply moves the operating levers 30 from the engaged position, to the disengaged position, thereby pulling the
inner surface 24 of the suction cup away from theupper surface 40 of the toilet pan and allowing air at atmospheric pressure to enter the cavity now formed (or enlarged) adjacent theinner surface 24 of the suction cup. - The suction cups can be covered by the body portion or cover means so as to hide the same from view from a user when the
attachment mechanism 2 is viewed externally when in an engaged position. - Referring to
figures 2a-2c , there is illustrated a further embodiment of anattachment mechanism 100 not according to the present invention. The same features are referred to by the same reference numerals used in the embodiment shown infigures 1a-1b . - Whereas the embodiment shown in
figures 1a-1b required a toilet pan to be formed where no existing toilet seat attachment apertures are provided on theupper surface 40 of thetoilet pan 42, any toilet seat attachment apertures provided are covered up using cover means, or the spacing between thesuction cups figures 2a-2c has locatingpins 102 which are for location in the existing toilet seat attachment apertures present on theupper surface 40 of atoilet pan 42. - The locating
pins 102 are provided onbase surface 8 of theattachment mechanism 100 and protrude outwardly and downwardly thereof. Asingle suction cup 20 is provided centrally between the locatingpins 102 onbase surface 8. Apump 104 is associated with thesuction cup 20 for removing air that may reside in the cavity formed between theinner surface 24 of the suction cavity and the upper surface of the toilet pan when in the disengaged position, in order to form the engaged position. User actuation means in the form of a pump operating lever orpiston 106 is accessible viaupper surface 6 of theattachment mechanism 100 to allow actuation of the pump to help remove air from the suction cavity of the suction cup. - In this embodiment, engagement means in the form of
hinge support straps 108 are providedadjacent ends upper surface 6 to allow a toilet seat to be hingedly mounted to the same. Thehinge support straps 108 protrude outwardly fromupper surface 6 and each have anaperture 110 defined therein for the location of a hinge pin therethrough in use. The hinge pin is associated with the toilet seat to be fitted to theattachment mechanism 100 in use. - It will be appreciated that any or any combination of the features in the embodiments shown in
figures 1a-1b andfigures 2a-2c can be provided to form an attachment mechanism not forming part of the present invention. - Referring to
figures 4a-8 , there is illustrated an embodiment of the present invention wherein the vacuum or partial vacuum in the suction cup is created, maintained and/or released by a vacuum pump that is actuated by movement of the toilet lid. - In this embodiment, the
attachment mechanism 200 includes ahousing 202 having a base 204 to which asuction cup 206 is attached. Asleeve member 208 is provided on a top 210 of thehousing 202 in which avacuum pump mechanism 212 is associated. In use, thesuction cup 206 is located on an upper surface of a toilet pan to which the toilet seat and lid is to be attached to in use. - An
aperture 214 is defined in thesuction cup 206 and this aperture is in communication withsuction conduit 216 attached to avacuum pump 218. Activation of the vacuum pump causes air or fluid to be sucked from the area between thesuction cup 206 and the toilet pan surface viasuction conduit 216 in use. - A cam head or
member 220 is associated with an end of the vacuum pump. Thecam head 220 cannot undergo rotational movement but is capable of undergoing linear reciprocal movement in a direction parallel to the longitudinal axis of thesleeve member 208 in which it is located. This linear reciprocal movement of thecam head 220 allows activation and deactivation of the vacuum pump in use. - A
shaft 222 is provided having afirst end 224 with acam member 226 provided thereon. Asecond end 228 ofshaft 222 has a profile that is complementary to the profile of a toilet seat attachment. In particular,second end 228 is provided with a plurality of teeth arranged adjacent the peripheral edge ofend 228 which engage with complementary recesses provided on an interior wall of asleeve element 230 associated with atoilet seat 232. Thus,shaft 222 is engaged to thetoilet seat 232 viasecond end 228. As thetoilet seat 232 is raised and lowered, this causesshaft 222 to pivot around its longitudinal axis 'x'. -
Cam member 226 is an eccentric cam member, such that rotation or pivoting ofshaft 222 causeseccentric cam member 226 to rotate.Eccentric cam member 226 does not undergo longitudinal movement alongsleeve member 208. However, due to the profile of theeccentric cam 226, which is complementary in shape to the profile ofcam head 220, rotation ofcam member 226 causescam head 220 to move longitudinally alongsleeve member 208, thereby activating or deactivating thevacuum pump 218. - In the illustration, opening of the
toilet seat 232 causes deactivation of the vacuum pump or the vacuum pump to be fully open or relatively extended in terms of its travel capability, as shown infigures 6a and 7b . Closing of the toilet seat causes activation of the vacuum pump or the vacuum pump to be fully closed or relatively depressed or recessed in terms of its travel capability, as shown infigures 6b and 7a . Activation of the vacuum pump, sucks air or fluid from thesuction cup 206, thereby increasing the suction force of the suction cup to the toilet pan in use. - The toilet seat mechanism can be used to replenish the vacuum in the
suction cup 206 during use or it can be used to create the vacuum in the suction cup. If the toilet seat mechanism is being used to replenish the vacuum in the suction cup only, user actuation means can be provided to allow the initial vacuum to be created and/or released as described previously. - It will also be appreciated that instead of the mechanical cam activation mechanism, a pressure sensor and/or switch can be provided to detect a pressure or pressure change in the suction cup. If the vacuum in the suction cup needs to be replenished, improved, reduced and/or the like, a battery operated mechanism can be used to activate or deactivate the vacuum pump to increase or decrease the vacuum in the suction cup. It will also be appreciated that the above mechanism can be used with the toilet lid and the toilet seat. A soft
