Definitions
- the present invention relates to a toilet seat lifting apparatus for promoting hygiene and cleanliness in public and/or domestic environments.
- the invention particularly, though not exclusively, relates to a lifting apparatus which is retrofittable between existing toilet bowls and seats and which employs a resilient spring for supplying a continuous lifting force to urge a toilet seat upwards away from the toilet bowl.
- a toilet seat lifting apparatus comprising:
- the helical spring has a variable internal and/or external diameter along its length between its opposite distal ends, and is connected between the first member and the underside of a toilet seat in order to urge the toilet seat away from the first member.
- a consequence of the invention is that a prospective seated toilet user must make physical contact with the toilet seat to lower it into a position for sitting.
- a prospective seated toilet user must make physical contact with the toilet seat to lower it into a position for sitting.
- a scenario is already commonly encountered in conventional toilet apparatus.
- a second member is provided for attachment to the underside of a toilet seat, and for connection to the energy storage member.
- the helical spring is a conical spring.
- the conical spring is telescopically compressible into a planar spiral.
- the helical spring when fully compressed the three-dimensional spatial volume occupied by the conical spring should be minimised to allow a toilet seat to adopt its intended horizontal orientation upon a toilet bowl.
- other technical aspects of the helical spring may be varied to provide desired energy storage and behavioural characteristics such as, for example: wire pitch, coil gap, helix angle, wire material, and wire diameter.
- wire diameter may vary along the length of the coil spring in a manner which delivers a more even and/or gentle release of stored energy (with a view to enabling it to raise a toilet seat weight of at least 1kg), i.e. thus mimicking conventional soft-close mechanisms, but in reverse.
- the aforementioned technical aspects of the helical spring may be altered in isolation or in combination over all or part(s) of the helical spring.
- the helical spring has a continuously curving central longitudinal axis.
- the continuously curving central longitudinal axis does not trace the arc of a circle.
- the first member comprises a generally C-shaped bracket to facilitate its attachment to a rear part of a toilet bowl rim.
- At least a lowermost part of the C-shaped bracket is adjustable and/or inclined to enable it to grip to toilet bowl rims of differing shapes and/or depth and/or thickness dimensions.
- the lowermost part of the C-shaped bracket includes two spaced apart gripping surfaces for securing it in position within a recess on a rimless or non-conventional toilet bowl structure.
- the second member comprises an elongate load-spreading bar for attachment across a lower part of the underside of a toilet seat.
- the elongate load-spreading bar includes one or more securing members for securing it in position on the underside of a toilet seat.
- the C-shaped bracket and elongate load-spreading bar may be formed from metallic and/or plastics materials (or plastic coated metallic materials to facilitate cleaning and prevent corrosion) and secured in position in a number of different ways including, but not limited to, via screw fixings, resilient clips or fasteners, self-sealing suction cups, adhesives, including epoxies, welding etc.
- opposite distal ends of a conical spring are secured to the C-shaped bracket and elongate load-spreading bar, respectively.
- the conical spring is provided with a flexible sleeve or cover.
- the sleeve or cover will provide a physical barrier preventing ingress of liquid or solid contaminants or detergents that may otherwise compromise the functioning or longevity of the spring and be difficult or impossible to properly clean thus countering the hygiene and cleanliness credentials of overall apparatus.
- the cover or sleeve may be compressible - e.g. in a concertina fashion.
- the cover or sleeve may be washable and/or removable.
- the cover or sleeve may be provided in a range of colours to match or compliment the colour scheme of the toilet seat and/or toilet bowl.
- the cover or sleeve may comprise surface indicia such as branding and/or marketing messages.
- the cover or sleeve can therefore be provided as a low cost consumable item that is replaceable on a regular basis. This may reduce or avoid the necessity for cleaning; and provides an opportunity to change or update marketing messages over the lifetime of the product to generate revenue.
- the widest distal end of the conical spring is secured to the C-shaped bracket, and the narrowest distal end of the conical spring is secured to the elongate load-spreading bar.
- the narrowest distal end of the conical spring is secured to the C-shaped bracket, and the widest distal end of the conical spring is secured to the elongate load spreading bar.
- this alternative orientation further distributes the load applied to the toilet seat across a wider surface area thus minimising the risk of structural damage thereto.
- a toilet seat lifting apparatus according to the first aspect to a toilet, the method comprising:
- the method includes securing a second member to the underside of the toilet seat, and connecting it to the energy storage member.
- a toilet comprising a toilet seat lifting apparatus according to the first aspect.
- a toilet comprising a toilet seat lifting apparatus according to the first aspect comprising a toilet bowl rim, wherein the energy storage member is connected between the first member, which is integrally connected to the toilet bowl rim, and a seat of the toilet in order to urge the toilet seat away from the toilet bowl.
- a second member is provided for attachment to the underside of the toilet seat, and for connection to the energy storage member.
- a computer-readable medium having computer-executable instructions adapted to cause a 3D printer to print the components of a toilet seat lifting apparatus according to the first aspect.

- Figs. 6a-c show three alternative flexible sleeve members for covering the conical helical spring of a toilet seat lifting apparatus according to the present invention
- Figs 7a-c show diagrammatic side schematic views of a toilet seat lifting apparatus of the present invention in a fully open position; an intermediate (partially open) position; and a fully closed position.
- the toilet seat lifting apparatus 10 of the present invention comprises an assembly of three main parts.
- a first member 12 in the form of a C-shaped or G-shaped bracket is provided for engagement with a toilet bowl rim (see Fig. 3).
- the bracket 12 comprises a substantially planar base wall 12a; a substantially planar upper wall 12b extending perpendicularly from the uppermost edge of the base wall 12a; and a relatively shorter lower wall 12c extending perpendicularly from the lowermost edge of the base wall 12a.
- the lower wall 12c is provided with a pair of threaded apertures 12d for receiving fixing bolts 14 from below.
- the walls 12a-c of the bracket 12 may be formed integrally from a single piece of material such as a metal, plastic or alloy. Though not shown in the Figs, the bracket 12 may be coated with a plastics material for corrosion resistance and aesthetic purposes.
- the uppermost surface of the upper wall 12b is provided with a fixing plate 16 in the form of a bar or rod mounted centrally thereon and extending across substantially the entire width of the upper wall 12b.
- the bar or rod 16 may be secured on the upper wall 12b by a central fixing bolt 14.
- the fixing bolt 14 may extend through a spacer such as a washer (not shown) to maintain a predetermined spacing between the bar or rod 16 and the upper wall 12b, respectively.
- Alternative ways to secure the C-shaped bracket to the bowl will be apparent to a person of ordinary skill in the art. For example, in the alternative embodiment of Figs.
- the lowermost wall 12c of the C-shaped or G-shaped bracket 12 terminates in an upwardly inclined lip 15 orientated at approximately 45 degrees to the horizontal.
- the inclined lip 15 permits a degree of tolerance by allowing the bracket 12 to grip a range of toilet bowl rims of differing rim wall thicknesses.
- This alternative embodiment also obviates the need for the threaded apertures 12d and fixing bolts 14 shown in the embodiment of Fig. 1.
- the base wall 12a of the embodiment of Figs 4a and 4b is slimmer than that of the embodiment of Fig. 1.
- the base wall 12a is contoured across its width, either in whole or part, such that it may fit more closely and unobtrusively against toilet bowl rim walls having either flat or curved surfaces.
- a second member 20 in the form of an elongate load-spreading bar is provided for engagement with the lowermost part of a toilet seat (see Fig. 3).
- a threaded aperture 22 is provided proximate each opposing end of the load-spreading bar 20 for receiving fixing bolts 24.
- a fixing plate 26 in the form of a short bar or rod mounted centrally thereon and extending across a central part of its overall width.
- the bar or rod 26 may be secured thereon by a central fixing bolt 24.
- the fixing bolt 24 may extend through a spacer such as a washer (not shown) to maintain a predetermined spacing between the bar or rod 26 and the surface of the load-spreading bar 20.
- An energy storage member 30 in the form of a conical helical spring is connected between the bracket 12 and the load-spreading bar 20.
- the aforementioned predetermined spacings between the respective bars or rods 16, 26 and the respective surfaces of the bracket 12 and load-spreading bar 20 are selected to closely match the wire diameter of the conical helical spring 30. In this way, the opposite coiled ends of the conical helical spring 30 can be wholly located within those predetermined spacings to secure them against detachment in the direction of the spring’s central longitudinal axis X-X.
- the first end 30a of the conical helical spring 30 which is connected to the bracket 12 has a relatively larger diameter (e.g, 23 mm) than its second end 30b (e.g. 15 mm) which is connected to the load-spreading bar 20.
- the helix angle and wire-width (e.g. 1.6 mm) of the conical helical spring 30 may be selected such that it is fully telescopically compressible into a planar spiral orientation.
- the central longitudinal axis X-X of the conical helical spring 30 is curved when in a relaxed (unloaded) state.
- the gradient of the curve changes continuously along its length such that the axis X-X does not follow the arc of a circle.
- the angular displacement between the first and second ends 30a, 30b of the conical helical spring 30 is greater than 45 degrees, but less than 90 degrees.
- a flexible sleeve 50 may be fitted around at least the conical helical spring 30 to conceal it from view and provide a physical barrier preventing ingress of liquid or solid contaminants or detergents.
- the sleeve 50 may be compressible/deformable, e.g. in a concertina fashion.
- the sleeve may be washable and/or removable.
- the sleeve may be provided in a range of colours to match or compliment the colour scheme of the toilet seat and/or toilet bowl.
- the sleeve may comprise surface indicia such as branding and/or marketing messages. As shown in Fig. 6a, one option is to shrink-wrap the spring 30 in a plastic material.
- FIG. 6b An alternative option exemplified in Fig. 6b provides a collapsible rubber outer sleeve that encases and seals the entire spring assembly.
- the thicker rubber material affords greater strength and flexibility through use as compared to shrink-wrapped plastic at the expense of a higher material cost.
- the thickness of the rubber material means that it must be over-sized and so its footprint is necessarily larger and hence more visually obvious.
- a further alternative option exemplified in Fig. 6c provide a multi- panelled spring-loaded plastic splash guard that extends into position over the spring 30 as the toilet seat is raised. When lowered each panel retracts back beneath the adjacent panel in an overlapping fashion.
- Each panel may be manufactured from an anti-bacterial plastic. Whilst this may be the most expensive option, i.e. due to inter-fitting plastic moulded parts, it arguably provides superior longevity and functionality, and presents convenient surfaces for branding or marketing messages.
- the toilet seat lifting apparatus 10 is shown fitted between a toilet bowl and toilet seat in Fig. 3.
- G-shaped bracket 12 is shaped to generally conform with the profile of the rear rim 42 of a toilet bowl 40. Its upper wall 12b rests on the upper peripheral surface of the rear rim 42; and its lower wall 12c extends under the rear rim 42.
- the fixing bolts 14 (not shown in Fig. 3) extend through their threaded apertures 12d and behind the rear rim 42 of the toilet bowl 40 to secure the G-shaped bracket 12 against detachment therefrom.
- the elongate load-spreading bar 20 is connected to the lower part of a toilet seat 44.
- this connection is by means of fixing bolts 24 extending through the threaded apertures 22 and into the underside of the seat surface.
- connection of the load spreading bar 20 to the toilet seat 44 is simplified by the curved nature of the conical helical spring 30 which presents the load-spreading bar 20 towards the seat.
- physical attachment of the load-spreading bar 20 to the toilet seat 44 may provide a more robust apparatus which also deters theft and/or vandalism is not mandatory. However, such a physical attachment is not mandatory since the curved nature of the spring 30 applies the opening force in the correct direction.
- Figs 1 to 4 enable the bracket 12 to hook behind the recess of a conventional toilet bowl rim 42 (see Fig. 3).
- Figs. 5a-c It is increasingly common for modern toilet bowls to be rimless, at least at its central point proximate a toilet seat. Fitting a toilet seat lifting apparatus to such toilet bowls requires a modified structure as shown in Figs. 5a-c.
- the bracket 12 of this embodiment is equivalent to the bracket 12 of the embodiments already described above with the exception of the structure of its lowermost wall 12c.
- the lowermost wall 12c now takes the form of a generally C-shaped member each end of which terminates in an upwardly inclined lip 15 orientated at approximately 45 degrees to the horizontal.
- the spaced-apart lips 15 engage within correspondingly spaced-apart recesses provided laterally of a central rear wall of a non-standard "rimless” toilet bowl (see Fig. 5c).
- this alternative structure maintains, to a significant degree, the same parts of the brackets 12 already described above. Conveniently, this means that only a single part requires to be swapped out to accommodate rarer, non-standard toilet bowl configurations.
- This alternative structure also enhances rigidity by resisting rotational forces acting on the lower part of the bracket 12 since the attachment to the toilet bowl is at two spaced-apart positions as shown in Fig. 5c.
- the lowermost wall 12c may be variable in length to control the separation of its upwardly inclined lips 15, thus enabling a single bracket to fit to different non-standard "rimless” toilet bowls with differently spaced surface recesses.
- Fig. 7a shows the toilet seat lifting apparatus 10 in its fully open position whereby its curved conical helical spring 30 is substantially de-energised having already urged the toilet seat 44 away from the toilet bowl 40 beyond 90 degrees via spring force Fs. Accordingly, the toilet is automatically presented to a standing user in a manner ready for use without any requirement for intervention by a user.
- the continuously curved central longitudinal axis X-X of the conical helical spring 30 means that the spring force applied at its opposite ends 30a, 30b is directed substantially perpendicularly with respect to the respective reaction surfaces of the toilet bowl 40 and toilet seat 44.
- a flexible sleeve 50 may cover the conical helical spring 30 such that the apparatus 10 is visually unobtrusive during normal use.
- Fig. 7b shows the toilet seat lifting apparatus 10 in an intermediate (partially open) position whereby its conical helical spring 30 is partially energised due to the toilet seat 44 being pivoted about its hinge towards the toilet bowl 40 by a prospective sitting user by application of a manual force FM which is greater than the spring force Fs.
- the prospective sitting user can have confidence that the toilet seat 44 will be free of accidental contamination by virtue of its default raised position.
- the orientation of the curved conical spring 30 described above means that the initial resistance to its compression is low, i.e. due to its smaller diameter end 30b being compressed first. It will also be appreciated that when a manual compression force is removed, the illustrated orientation of the curved conical spring 30 will also provide a diminishing speed of the lifting movement of the seat, i.e. a "soft-opening”.
- Fig. 7c shows the toilet seat lifting apparatus 10 in a fully closed position whereby its conical helical spring 30 is fully energised due to the toilet seat 44 being pivoted about its hinge such that it lies horizontally upon the toilet bowl 40 due to a user’s weight W.
- the configuration of the conical helical spring 30 is such that, when fully compressed, its coil wires telescopically collapse to lie in a planar spiral, i.e. the conical helical spring 30 lies substantially flat between the underside of the toilet seat 44 and the upper surface of the toilet bowl 40.
- the vertical space within which all parts of the toilet seat lifting apparatus 10 must be accommodated i.e. the bracket, spring and load-spreading var) is typically at most 2 cm high.
- the technical features of the present invention ensure that high standards of hygiene and cleanliness are maintained without the need for any purposeful action on the part of a standing toilet user. Furthermore, the benefits of the present invention can be realised without the need to disassemble and remove a toilet seat. Retrofitting and/or replacement of parts can be performed easily without the need for any technical expertise or special tools thus making it a cost-effective option.
- the advantages of the present invention include that maintenance and cleaning costs for public toilets can be reduced.
- the C-shaped bracket and elongate load-spreading bar may be formed from metallic and/or plastics materials (or plastic coated metallic materials to facilitate cleaning and prevent corrosion) and secured in position in a number of different ways including, but not limited to, via screw fixings, resilient clips or fasteners, self-sealing suction cups, adhesives, including epoxies, welding etc.
- toilet lids incorporate a soft closure mechanism and so it may be necessary to balance the respective spring forces of the toilet seat lifting apparatus according to the present invention against those of any lid soft closure mechanism to ensure optimum performance of those two features.
- each of the springs may be provided with an individual sleeve or cover.
- a single sleeve or cover may be provided for fitting over all springs.
- the bracket of the present invention may be provided with features of adjustability enabling it to be attached to a wide range of toilet bowl rims of different shapes and dimensions.
- the part(s) of the bracket which project under the toilet bowl rim may also need to be adapted to avoid obstruction of the flow dynamics of flushing water.
- the illustrated embodiments show a fully retrofittable toilet seat lifting apparatus having a bracket which is removably attached to a toilet bowl rim, it would equally be possible to incorporate a suitable connection feature into the toilet bowl rim at the time of manufacture thus providing a stronger and less visually intrusive manner of attaching the energy storage member thereto.
