1. Field of the Invention
The present invention relates to a platform, and in particular, a height adjustable platform suitable for supporting a toilet bowl.
2. Description of the Related Art
Conventionally flushing toilets include a toilet bowl having an upper rim onto which is affixed a hinged top forming a seat base for a user, and a water cistern containing a reservoir of water for flushing purposes forming a seat back. The toilet bowl is typically secured to a floor surface at its base end, with its rear abutted against a wall. A soil pipe exits the rear of the toilet, which is usually routed downwardly through the wall of a building to join a mains sewer.
Toilet bowls tend to be universal in height, with the seat typically being in the region of fifteen inches from floor level. This standard height of the toilet bowl is selected as being the optimal height for use by a majority of users. However, this height can cause problems for certain groups of users, for example, those with physical disabilities, or elderly users with limited mobility, for whom manoeuvring from the standing to the seated position, and vice versa, can be difficult. For such users a relatively taller toilet bowl is desirable to reduce the distance by which they must lower themselves to the seated position, so that they may descend and rise from the sitting position more easily.
It is known in the prior art to provide a toilet seat riser, in the form of a generally U-shaped block with a height that is relatively greater than conventional toilet seat, which is fitted to the upper rim of the toilet bowl thus effectively raising the height of the toilet bowl. Such risers are often constructed of a padded fabrics materials for improved comfort, and can optionally include a hinged lid to allow installation in substitute of the existing toilet seat.
However, a number of problems are experienced with conventional seat riser apparatus. In the first instance, seat risers tend to be offered in a range of standard heights, meaning that a user is restricted to a height that may not be optimal for their condition. Seat risers are available in which the height of the riser, and so the height added to a toilet bowl, is adjustable in use. However, the height is typically adjustable only in discrete increments, for example, in increments of fifty millimetre.
Moreover, such devices incur significant disadvantages both in terms of aesthetic appearance, and in hygiene. In the first instance, the seat riser is above the region of the toilet bowl that is cleaned by the flush of water, and as a result can tend to become contaminated in use. Due in part to problems with maintaining cleanliness, it is common for users of a shared toilet who do not require the additional height, to remove the seat riser before using the toilet, necessitating frequent detachment and refitting of the device, resulting in material fatigue and eventual failure.
In view of the aforementioned limitations to existing devices, it is desirable to provide an alternative means for raising the height of a toilet bowl.
According to a first aspect of the present invention, there is provided a platform for supporting a toilet bowl, the platform comprising a base member for engaging a ground surface; a top member for attachment to a toilet bowl; and a support member extending between the base member and the top member, the support member being configured to support the top member at a distance from the base member.

In order to better understand the present invention, and to show more clearly how an exemplary embodiment thereof may be carried into effect, reference will now be made, by way of example only, to the accompanying drawings, in which:
An example of an environment in which apparatus according to the present invention can be used is shown in
Toilet 101 comprises generally of a toilet bowl 104, a water cistern 105 containing a reservoir of water for toilet flushing purposes and equipped with an internal flushing mechanism, and a seat top 106, hingedly connected to the toilet bowl, the conventional arrangement of which will be entirely familiar to the skilled person. Toilet bowl 104 defines a substantially bowl shaped stool, extending from a base end 107, upwardly to a generally circular rim 108. As will be understood, the height of the toilet bowl, that being the distance between the base end 107 and the rim 108, is generally selected such that the toilet bowl may function as a seat for a user, who may rest on the rim of the bowl in a squatted position.
Toilet bowl 104 is mounted on a platform 109 according to one embodiment of the present invention, which platform supports the toilet bowl in an elevated position with respect to ground surface 102. Platform 109 comprises of a base member 110, and a top member 111, the top member being adapted for attachment to a bottom surface of the toilet bowl as illustrated. Toilet bowl 104 is attached to the top member 111 by way of attachment means 112, which pass through slots defined in the top member as will be described. Base member 110 is securely attached to the ground surface by way of screws, such as screws 113, 114, which pass through apertures in the base member and engage the ground surface.
Platform 109 further comprises a plurality of support members 115, 116, 117, 118 (support member 118 omitted from view), in the form of elongate rods, positioned generally in each corner of the platform, connected at a first end to the base member 110, and extending generally orthogonally therefrom, upwardly to the top member 111, which support the top member 111 at a distance d1 from the base member. In supporting the top member 111 above the level of ground surface 102, the platform supports the toilet 101 in an elevated position, thus raising the height of the rim 108 of the toilet bowl with respect to the ground surface by a distance d1.
In the specific embodiment illustrated and to be described, platform 109 is configured as a height adjustable platform for supporting a toilet bowl, in which the height of the platform may be adjusted to vary the distance between the base member and the top member, as will be described further with reference to
As illustrated, in use the platform is secured to the ground surface, and the toilet bowl is placed on the upper surface of the top member 111, and attached thereto. The height of the platform is adjusted to that required by the user, which may be dependent on their height and/or physical mobility, and the toilet is then ready for use. It will of course be appreciated that, particularly where the platform is to be installed on a permanent basis, the platform may be concealed from view by the addition of decorative side and top panels. This may be particularly desirable where the platform is to be installed permanently in a domestic bathroom, where the platform could be boxed in using conventional construction techniques, and carpeted over so as to match the surrounding ground surface.
Top member 111 is shown in an underside plan view in
Top member 111 defines a pair of parallel elongate slots 202 and 203, which extend lengthways along a portion of the top member, and penetrate right through the top member to define elongate apertures, each having a diameter of circa ten millimetres. Slots 202, 203 are configured to receive attachment means 112, which in the embodiment are ten millimetre gauge threaded bolts, which are passed through apertures in a flange at the base of the toilet bowl, and extend through the slots in the top member, with a nut and washer being provided to securely attach the toilet bowl to the top member. In this way, by slackening the nuts on the securing bolts, the toilet bowl may be slidably moved along the length of the top member, to allow correct alignment of the toilet to be achieved, for example, to facilitate routing of the soil pipe.
Top member 111 defines apertures 204 to 207, having a diameter of circa twelve millimetres, through which the elongate supporting members 115 to 118 are passed downwardly from the upper surface of the top member, as will be described further with reference to
Top member 111 is further provided with brackets 208, 209, at the front edge of the underside surface, configured to receive ancillary attachments, for example, a foot rest, to assist a user when using the toilet.
The base member 110 is shown in a top plan view in
Base member 110 is substantially similar in construction and dimension to the top member 111 described previously with reference to
Base member 110 is provided with a plurality of apertures 302, 307, having a diameter of circa eight millimetres. Apertures 302 to 307 are configured for receiving screws, such as screws 113 and 114 described with reference to
Base member 110 further includes a plurality of brackets, 312 to 317, which are used for securing auxiliary attachments to the base member. In the specific embodiment illustrated, brackets 312 to 315, are provided on the upper surface of the base member adjacent the side edges of the plate, and configured to receive a pair of hand rails (not shown), which extend upwardly from the base member to be approximately level with the height of the rim of the toilet bowl. In a preferred embodiment of the invention, a pair of ambidextrous hand rails are provided as a removable part of the platform, for attachment to the base member, to assist a person with limited mobility in using the toilet. Brackets 316 and 317 are provided at the front edge of the base member for receiving a foot rest attachment, on which a user may rest their feet while using the toilet.
The platform apparatus 109 is shown in side cross section views in
Platform 109 is shown in
Top member 111 is provided above the base member 110, along a plane that is substantially parallel with the plane of the base member. In the embodiment, the top member 111 is further provided with a mat 401, comprised of an elastomeric material, for example, rubber, covering its upper surface 201. Toilet bowl 104 is placed on the top member 111, with its bottom surface in contact with the mat 401 on the upper surface of the top member, and secured to the top member 111 by bolts passing through slots 202, 203, as described previously.
In the specific embodiment, the support members 115 to 118, each comprise an elongate threaded metal rod, with a diameter of around twelve millimetres and having a first end 402 defining a hex head, and a second end 403, and a helical thread extending along the rod between the first and second ends. Support members 115 to 118, are passed through apertures 204 to 207 in the top member 111, and downwardly through apertures 308, 311 in the base member. In the embodiment, base member 110 further comprises a weld nut 404, 405, welded to the lower surface of the base member adjacent each said aperture 308 to 311. Thus, the distal end of each said elongate support member is passed through its respective aperture 308 to 311, in the base member 110, and threaded through the weld nut 404, 405. Said elongate support members 115, 118 each further comprise a pair of hex nuts, such as hex nuts 406 and 407, interposed along the length of the rod between said first and second ends.
Platform 109, is shown in a first configuration in
In the embodiment, the distance between the plates d2 is in the region of four hundred millimetres, and thus the platform 109 is adjustable in height between fifty millimetres and four hundred millimetres. It will of course be appreciated however, that in alternative embodiments, the platform may be adjustable in height over a greater range, for example, from ten millimetres to one thousand millimetres, depending on the environment in which it is to be used.
The base member and the top member are axially aligned along the axis 408 which extends orthogonally through the centre point of said base and top members, that is to say the top member is directly above the base member, and the top member is movable along said axis, upwardly and downwardly generally vertically relative to said ground surface.
Support members 115 to 118 are adjustable, by way of rotating the elongate rods 115, 118 with respect to the weld nuts 404, 405, and by repositioning the nuts 406, 407, so as to increase or decrease the distance between the base member and the top member. In the embodiment, the elongate threaded rods are passed downwardly through the top member and the base member of the platform, with the hex head 402 resting against the upper surface of the top member. In this way, the hex head remains accessible even once the platform and toilet are installed as described, allowing further height adjustment.
The platform apparatus 109 is shown in an end cross section view in
As has been described, the plurality of support members 115 to 118 support the top member at a distance from the base member, and may be adjusted to increase or decrease the distance between the base member and the top member, and thereby vary the height of the platform. In the specific embodiment of the invention illustrated, the platform is provided with a plurality of support members, in the form of elongate threaded rods, positioned generally at each corner of the platform.
The distance between the base member and the top member is adjusted by rotating the threaded rods relative to the hex nuts, which hold the base member and the top member in position along the length of the rod. In this way, as each threaded rod is rotated clockwise, the rod is drawn downwardly through the weld nut positioned on the lower surface of the base member, thus lowering the top member with respect to the base member. The second end of the elongate threaded rods are lowered into cavities formed for this purpose in the ground surface. Once all four support members are adjusted to the required height, and such that the top member is level relative to the ground surface, the nuts 406, 407 of the support members, may be adjusted so as to securely clamp against the lower and upper surface of the top and base members respectively, thereby creating a stable structure for supporting the toilet.
A second platform 601 according to a second embodiment of the present invention will now be described with reference to
Referring particularly to
Similarly to the platform 109 described with reference to
In a similar manner to platform 109, platform 601 further comprises a plurality of (substantially like) support members 610, 611, 612, 613, extending between the base member 602 and the top member 603, the plurality of support members being configured to support the top member 603 at a distance from the base member 602.
As will be described further with reference to
Said platform 601 comprises a plurality of support members, in the specific embodiment, four substantially like support members 610 to 613. The plurality of support members are arranged in two pairs, said first pair 618 comprising support members 610 and 611, and said second pair 619 comprising support member 612 and 613, the support members in each pair being pivotally coupled about a pivot point 620, 621 positioned between the respective ends of the support members. In the particular embodiment, the pivot point 620, 621 is located approximately equidistant between the respective ends of each support member. In the embodiment, said coupled pairs of support members 618, 619 are mutually connected, such that the pairs together support the top member 603 with respect to the base member 602. Thus, as illustrated, a first support member in each said pair 618, 619, in this case said support members 611, 613 are each rigidly coupled adjacent a respective lower end to shaft 622. The outer ends of said shaft 622 are rotatably received by like brackets 623, which brackets 623 each include a rolling bearing element configured to engage the respective outer end of the shaft 622 allowing the shaft 622 to rotate relative to brackets 623. Brackets 623 are in turn each rigidly mounted to the top surface 605 of said bottom member 602.
The upper ends of each support member 611, 612 are slidably coupled to said top member. In the embodiment, said top member 603 comprises brackets 624, 625 extending downwardly from the bottom surface 609 of the top member 603. Each said bracket 624, 625 defines an elongate slot 626, 627 within which a stub axle 628, 629 protruding from adjacent the upper end of each support member 611, 612 is received. In this way, the stub axles 628, 629 are free to move along the slots between its ends.
In a similar way, a second support member in each said pair 618, 619, in this case support members 610, 613, are each rigidly coupled adjacent a respective upper end to shaft 630. Similarly, the outer ends of said shaft 630 are rotatable received by like brackets 631 which brackets 631 each include a rolling bearing element configured to engage the respective outer end of the shaft 630 allowing the shaft 630 to rotate relative to brackets 631. Brackets 631 are in turn each rigidly mounted to the bottom surface 609 of said top member 603.
The lower ends of each support member 610, 613 are each rotatably coupled to shaft 632 adjacent respective outer ends of the shaft. The outer ends of shaft 632 are then slidably received in elongate slots 633, 634, substantially identical to elongate slots 626, 627, in said upwardly extending side wall 607. In this way, the shaft 632 is free to move along the slots 633634. In the specific embodiment, said shaft 632 is in actuality comprised of two separate shaft halves, first half 635 and second half 636. Said first and second halves 636, 637, are rigidly coupled by way of coupling block 638.
Thus, it will be appreciated that the operation of said pairs of coupled support members 618, 619 is scissor-like, to thereby allow adjustment of the distance between the base member 602, and the top member 603.
The platform 601 previously described with reference to
In
In
Referring to the Figures, said platform 601 is provided with motor apparatus (indicated generally at 637) configured to adjust the configuration of the support members 610 to 613 to thereby vary the distance between the base member 602 and the top member 603. In the embodiment, motor apparatus 637 comprises an electric motor 614 rigidly mounted to the upper surface 605 of the base member 602 by way of fixing bracket 615.
As illustrated, motor apparatus 637 further comprises threaded rod 616, which rod defines externally a continuous helical thread extending the length of rod. Said rod 616 is mounted to the upper surface 605 of said base member 602 by way of brackets 617, 618, which brackets are equipped with a rolling bearing element configured to engage the rod 616 to allow rotation of the rod 616 relative to the brackets 617, 618, and base member 602. Rod 616 is rotatably coupled to an output shaft 801 of said electric motor.
As illustrated, rod 616 passes through a cylindrical hole defined through said coupling block 638 coupling the two halves 635, 636 of the shaft 632. The cylindrical internal surface of the coupling block 638 defines a helical thread corresponding to the helical thread of said rod 616. Thus, as will be understood, rotation of said threaded rod 616 relative to said coupling block 638 within said threaded hole results in axial movement of the rod 616 relative to the block 638 in a direction dictated by the direction of rotation of the rod 616. Given that axial movement of said threaded rod 616 is prevented by brackets 617, 618, rotation of said rod 616 causes said coupling block 638 to be wound along the rod 616 resulting in linear movement of the block 638.
Thus referring particularly to
Referring secondly to
As will be appreciated, movement of said coupling block 638 causes said shaft 632 to slide along said elongate slots 633, 634, in a direction generally away from the electric motor 614. Movement of the shaft 632 in turn causes the lower ends of said support members 610, 613, to be moved away from the lower ends of the support member 611, 612. As will be evident, movement of the lower ends of the support members 610, 613 away from the lower ends of the support members 611, 612, causes the pair of pivotally coupled support members to fold, thereby reducing the distance between the top member 603 and the base member 602. Thus, the configuration of motor apparatus 637 shown in
It will be understood that the embodiment of the present invention described with reference to
Whilst two specific embodiments of the invention have been described herein, it will of course be appreciated that a number of alternative suitable arrangements exist. In particular, it will be appreciated that various alternative types of support members are suitable for supporting the top member at a set distance from the base member. Indeed, in an alternative embodiment, the support members may comprise a plurality of hydraulic rams extending between the base member and the top member, which support the top member, and the length of which may be readily adjusted to vary the distance between the base member and the top member. In particular embodiments, the support members could be configured to support the top members in set positions, to allow adjustment of the distance between the top member and the base member in discrete increments. As an alternative, the support member may be configured to allow linear adjustment of the distance between the base member and the top member. In a further alternative embodiment, the platform is provided with only a single support member, which may for example be in the form of a central pillar extending between the base member and the top member.
Further, it will be appreciated that the arrangement of the support members 610 to 613 of platform 601 described with reference to
Moreover, considering the configuration of platform 601 described with reference to
It will however be appreciated that the arrangement of motor apparatus 637 described with reference to
Thus, in the configuration described with reference to
Furthermore, it is envisaged that the present invention may be provided as a kit of disassembled parts, as clearly assembly and adjustment is required in installing the product and mounting the toilet bowl. Thus, the present invention provides a kit of parts for assembling the platform used for supporting a toilet, described previously with reference to
Moreover, in a further embodiment of the invention, a toilet may be provided already equipped with the platform described herein, in which the top member is attached to the toilet bowl, for example, to a bottom surface of the toilet bowl, with the base member and the support members already assembled, such that the base member may be secured to a ground surface, and the support members may be then adjusted to set the distance between the base member and the top member to the required height.
