The present disclosure relates to an adjustable toilet seat arrangement for a toilet system. More particularly, the present invention relates to the adjustable toilet seat arrangement for the toilet system, comprising of a height varying mechanism for varying an overall height of the toilet seat arrangement thereof.
BACKGROUND
Toilet systems are known in sanitation industry, to enable persons to defecate in good sanitary conditions. A typical toilet system includes a toilet bowl (also referred to as a water closet) and a toilet seat arrangement. The water closet is provided to receive faecal matter when a user performs defecation thereon. The water closet has an ovoid shaped top closet surface with a top closet opening and an ovoid closet peripheral portion, to receive the faecal matter when a user performs defecation thereon. The toilet seat arrangement has an ovoid shaped top seat surface with a top seat opening and an ovoid seat peripheral portion, pivotally installed on the water closet. The toilet seat arrangement may be pivotally adjusted between a deployed configuration and a stowed configuration based on the user needs. For example, while using the toilet system for urination purposes, the toilet seat arrangement may be adjusted to the stowed position, wherein the ovoid shaped top closet surface of the toilet seat arrangement is positioned at substantially right angle to the top closet opening of the water closet. Similarly, while using the toilet system for defaecation purposes, the toilet seat arrangement may be adjusted to the deployed position, wherein the ovoid shaped top seat surface of the toilet seat arrangement is positioned abutted with the ovoid shaped top closet surface of the water closet.
Furthermore, in certain situations, such as based on a user’s anatomy, an overall height of the toilet seat arrangement is required to be adjusted. For example, when a user’s height is relatively lesser, a toilet seat arrangement with a relatively smaller height is required. Similarly, when a user’s height is relatively greater, a toilet seat arrangement is required to be adjusted to a relatively greater overall height. However, it may be noted that an overall height of the toilet seat arrangement is usually fixed and predefined. Accordingly, there exists a need for a toilet seat arrangement, of which the overall height can be adjusted, based on user’s needs.
Conventionally, a toilet seat arrangement includes a primary seat that is suitable for users with relatively lesser heights, and the overall height of the toilet seat arrangement is adjusted to minimum overall height. Moreover, when required to be used by users with relatively greater heights, a secondary seat may be removably installed over the primary seat, to increase the overall height of the toilet seat arrangement to the maximum overall height. Subsequently, for readjusting the overall height of the toilet seat arrangement to the minimum overall height, the secondary toilet seat is required to removed by use of external support systems, such as a bolt mechanism, or a paddle mechanism. Moreover, such secondary toilet seats are not only bulky and cumbersome, but also require extra effort in their installation and removal which causes inconvenience to the users.
Furthermore, the toilet system, in some embodiments, is also provided with a heating mechanism to heat the toilet seat arrangements. The heating mechanism includes a plurality of electric heating coils installed beneath the toilet seat arrangements, which are externally powered by a power source. These electric heating coils installed beneath the toilet seat arrangement hinders in proper cleaning of the toilet seat arrangement, leading to accumulation of dirt and germs. Moreover, a direct connection of the toilet seat with the electric heating coils also poses the risk of electric shock to the user who sits on the toilet seat arrangement.
Accordingly, in light of the aforementioned drawbacks and several other inherent limitations in existing prior arts, there is a well felt need to provide a toilet seat arrangement including a height varying mechanism and a heating unit for adjusting the overall height and temperature of the toilet seat arrangement.

Furthermore, in certain situations based on user’s anatomy, an overall height of the toilet seat arrangement [104] may require to be adjusted. In the present embodiment, the toilet seat arrangement [104] is suitably structured and arranged, such that the overall height of the toilet seat arrangement [104] can be varied, based on user’s demand. A structure and arrangement of the toilet seat arrangement [104] will now be explained in details hereinafter.
Figure 4a, 4b, 5a, 5b, 6a, and 6b, shows a sectional view of the toilet seat arrangement [104] of the toilet system [100] of Figure 1, illustrating various embodiments of a height restricting mechanism [118] of the toilet seat arrangement [104] thereof, in accordance with the concepts of the present disclosure. Figures 4a, 4b, 5a, 5b, 6a, and 6b, should be referred to in conjunction with each other, to clearly understand the concepts of the present disclosure. The toilet seat arrangement [104] includes an upper toilet seat member [112], a lower toilet seat member [114], a heigh varying mechanism [116], and a height restricting mechanism [118]. Each of the upper toilet seat member [112] and the lower toilet seat member [114] are made up of heat conductive material. The upper toilet seat member [112] and the lower toilet seat member [114], in combination, forms an external structure of the toilet seat arrangement [104]. In particular, each of the upper toilet seat member [112] and the lower toilet seat member [114] are ovoid shaped structures with a central opening defined therein. Further, each of the upper toilet seat member [112] and the lower toilet seat member [114] includes a first peripheral end portion [120a, 120b] (also referred to as “the external peripheral portions [120a, 120b]), a second peripheral end portion [122a, 122b] (also referred to as “the external peripheral portions [120a, 120b]), defining a dented portion therebetween. The first peripheral end portions [120a, 120b] of each of the upper toilet seat member [112] and the lower toilet seat member [114] are connected together via a first flexible member [124]. The second peripheral end portions [122a, 122b] of each of the upper toilet seat member [112] and the lower toilet seat member [114] are connected together via a second flexible member [126]. The first flexible member [124] and the second flexible member [126] maintain alignment of the upper toilet seat member [112] relative to the lower toilet seat member [114]. Further, as the upper toilet seat member [112] is mated with the lower toilet seat member [114], an enclosed space [128] is defined therebetween. The height varying mechanism [116] is deployed within the enclosed space [128] defined between the upper toilet seat member [112] and the lower toilet seat member [114], for varying an overall height of the toilet seat arrangement [104]. In particular, the upper toilet seat member [112] is raised relative to the lower toilet seat member [114] by the height varying mechanism [116], for increasing the overall height of the toilet seat arrangement [104]. Similarly, the upper toilet seat member [112] is lowered relative to the lower toilet seat member [114] by the height varying mechanism [116], for decreasing the overall height of the toilet seat arrangement [104]. A structure and arrangement of the height varying mechanism [116] will be described in details hereinafter.
The height varying mechanism [116] includes at least one expandable compartment member [130] and a fluid control system [131]. The at least one expandable compartment member [130] is made up of heat conductive material and is disposed within the enclosed space [128] of the toilet seat arrangement [104]. The at least one expandable compartment member [130] is a storage pouch type structure made up of flexible material, and at least partially attached to an inner periphery of the enclosed space [128] defined between the upper toilet seat member [112] and the lower toilet seat member [114]. In the present embodiment, the height varying mechanism [116] includes two expandable compartment members [130] namely a first expandable compartment member [130a] and a second expandable compartment member [130b]. However, it may be obvious to a person ordinarily skilled in the art that the height varying mechanism [130] can employ any number of expandable compartment members [130]. Each of the first expandable compartment members [130a] and the second expandable compartment members [130b] are at least partially attached to the inner periphery of the enclosed space [128] defined between the upper toilet seat member [112] and the lower toilet seat member [114]. Moreover, each of the first expandable compartment member [130a] and the second expandable compartment member [130b] are adapted to expand and contract respectively within the enclosed space [128], for vertically adjusting the upper toilet seat member [112] relative to the lower toilet seat member [114], when supplied with and sucked from fluid therein. Specifically, each of the first expandable compartment member [130a] and the second expandable compartment member [130b] are adapted to expand within the enclosed space [128], for vertically increasing an overall height of the toilet seat arrangement [104], when supplied with fluid therein. Similarly, each of the first expandable compartment member [130a] and the second expandable compartment member [130b] are adapted to contract within the enclosed space [128], for vertically decreasing the overall height of the toilet seat arrangement [104], when fluid is sucked therefrom.
Referring back to figure 2 and figure 3, there is shown the fluid control system [131]. The fluid control system [131], as is shown in figures 4a, 5a, and 6a, is adapted to supply fluid to each of the first expandable compartment member [130a] and the second expandable compartment member [130b] for expansion thereof, and thus increasing an overall height of the toilet seat arrangement [104]. Similarly, the fluid control system [131], as is shown in figures 4b, 5b, and 6b, is adapted to suck fluid from each of the first expandable compartment member [130a] and the second expandable compartment member [130b] for contraction thereof, and thus decreasing an overall height of the toilet seat arrangement [104].
The fluid control system [131] includes a fluid reservoir [132], a control box [134], and a control unit [136]. The fluid reservoir [134] is adapted to store fluid therein. The control box [136] is fluidly disposed between the fluid reservoir [132] and the expandable compartment members [130a, 130b] of the toilet seat arrangement [104]. A number of fluid conduits [140a, 140b, 140c, and 140d] are employed for establishing a fluid communication between the fluid reservoir [134] and the control box [134], and to establish the fluid communication between control box [134] and the expandable compartment members [130a, 130b] of the toilet seat arrangement [104]. Further, the control box [134] is adapted to operate in either of a first configuration and a second configuration. In the first configuration, the control box [134] receives the fluid from the fluid reservoir [132] and supplies the fluid to the expandable compartment members [130a, 130b]. In the second configuration, the control box [134] sucks back the fluid from the expandable compartment members [130a, 130b] and supplies the fluid to the fluid reservoir [132]. The control unit [136] is electrically connected to the control box [134], and is adapted to switch the control box [134] between the first configuration and the second configuration. In particular, the control unit [136] is a remote control that includes height controls for controlling the control box [134] to be operated between the first configuration and the second configuration, based on user’s demand. For example, when required, a user may operate the control unit [136], to adjust the control box [134] in the first configuration. In the first configuration, the control box [134] receives the fluid from the fluid reservoir [132] and supplies the fluid to the expandable compartment members [130a, 130b], to expand the increase the expandable compartment members [130a, 130b] and increase the overall height of the toilet seat arrangement [104]. In the second configuration, the control box [134] sucks back the fluid from the expandable compartment members [130a, 130b] and supplies the fluid to the fluid reservoir [132], to contract the expandable compartment members [130a, 130b] and decrease the overall height of the toilet seat arrangement [104].
The height restricting mechanism [118] is installed between the upper toilet seat member [112] and the lower toilet seat member [114], to restrict the overall height of the toilet seat arrangement [104] to a maximum height. Various embodiments of the height restricting mechanism [118], may be envisioned. In a first embodiment, the height restricting mechanism [118] is a sliding member [142]. In a second embodiment, the height restricting mechanism [118] is a flexible connection member [144]. In a third embodiment, the height restricting mechanism [118] is a scissor mechanism [146].
As is shown in figures 4a and 4b, in the first embodiment, the sliding member [142] as the height restricting mechanism [118] is a rod arrangement including a first slider end [142a], a second slider end [142b], and a middle slider portion [142c]. The sliding member [142] is installed such that, the first slider end [142a] is fixedly attached to the upper toilet seat member [112], the middle slider portion [142c] slideably passes through the lower toilet seat member [114], and the second slider end [142b] extends outwards of the lower toilet seat member [114] and defines a slider stop portion [142d]. In the lowered position of the toilet seat arrangement [104], as is shown in figure 4a, the slider stop portion [142d] is spaced apart from the lower toilet seat member [114]. In the raised position of the toilet seat arrangement [104], as is shown in figure 4b, the slider stop portion [142d] at the second slider end [142b] of the sliding member [142] abuts against the lower toilet seat member [114], to restrict the overall height of the toilet seat arrangement [104] to the maximum height.
As is shown in figures 5a and 5b, in the second embodiment, the flexible connection member [144] as the height restricting mechanism [118] is a rope including a first end [144a], a second end [144b], and a middle portion [144c]. The flexible connection member [144] is installed such that, the first end [144a] is fixedly attached to the upper toilet seat member [112], the middle portion [144c] passes through a hook portion [144e] in the lower toilet seat member [114], and the second end [144b] extends outwards of the lower toilet seat member [114] and defines a stop portion [144d]. In the lowered position of the toilet seat arrangement [104], as is shown in figure 5a, the stop portion [144d] is spaced apart from the hook portion [144e] in the lower toilet seat member [114]. In the raised position of the toilet seat arrangement [104], as is shown in figure 5b, the stop portion [144d] at the second end [144b] of the flexible connection member [144] abuts against the lower toilet seat member [114], to restrict the overall height of the toilet seat arrangement [104] to the maximum height.
As is shown in figures 6a and 6b, in the second embodiment, the scissor mechanism [146] as the height restricting mechanism [118] is scissor mechanism including a first scissor end [146a] and a second scissor end [146b]. The first scissor end [146a] is connected to the upper toilet seat member [112]. The second scissor end [146b] is connected to the lower toilet seat member [114]. The scissor mechanism [146] being expandable to an expansion height equivalent to the maximum height, thereby restricting the overall height of the toilet seat arrangement [104] to the maximum height.
Furthermore, it may be noted that the heating unit is also disclosed in the present disclosure, to heat the toilet seat arrangement [104]. The heating unit is a thermoelectric unit integrated with the control box [134] of the fluid control system [131], for controllably heating the fluid received therein form the fluid reservoir [132] to a temperature, before supplying the fluid to the expandable compartment members [130] in the first configuration thereof. The heating unit is electrically connected to and controlled by the control unit [136] of the fluid control system [131]. In particular, the control unit [136] may include heat controls that may be operated by a user, to adjust the temperature of heating the fluid in the control box [134] of the fluid control system [131] as received from the fluid reservoir [132] before supplying to the fluid to the expandable compartment members [130] in the first configuration thereof. The fluid been supplied at heated temperatures to the expandable compartment members [130], heats the toilet seat arrangement thereof.
In operation, a user may sit on the toilet set arrangement [104] to performs defecation thereon. Furthermore, when required to vary a height of the toilet seat arrangement [104], a user may operate the height controls of the control unit [136]. For example, when required to raise the overall height of the toilet seat arrangement [104], a user may press height increase controls on the control unit [136]. The control unit [136] accordingly sends signals to the control box [134] of the fluid control system [131], to operate the control box [134] in the first configuration. In the first configuration, the control box [134] receives the fluid from the fluid reservoir [132] and supplies the fluid to the expandable compartment members [130a, 130b], to expand the expandable compartment members [130a, 130b] and increase the overall height of the toilet seat arrangement [104]. Furthermore, in some situations, the overall height of the toilet seat arrangement [104] may require to be lowered. In such situations, a user may press height decrease controls on the control unit [136]. The control unit [136] accordingly sends signals to the control box [134] of the fluid control system [131], to operate the control box [134] in the second configuration. In the second configuration, the control box [134] sucks back the expandable compartment members [130a, 130b] and supplies the fluid to the fluid reservoir [132], to contract the expandable compartment members [130a, 130b] and decrease the overall height of the toilet seat arrangement [104].
Similar to the aforementioned operations for varying the overall height of the toilet seat arrangement [104], a temperature of the toilet seat arrangement may also be varied. For example, in the first configuration of the control box [134], the temperature of the toilet seat arrangement [104] may also be adjusted. In order to increase the temperature of the toilet seat arrangement [104], a user may press temperature increase control on the control unit [136] of the fluid control system [131]. The control unit [136] may accordingly send signal to the heating unit to adjust the temperature of the fluid as received from the fluid reservoir [132] to be supplied to the expandable compartment members [130]. Accordingly, such supply of heated fluid to the expandable compartment members [130] corresponds to heating of the toilet seat arrangement [104].
Various advantages exist for the present invention. One such advantage of the present invention relates to the height varying mechanism [116] of the toilet seat arrangement [104]. The height varying mechanism [116] is capable of varying the overall height of the toilet seat arrangement [104], by supplying or sucking back of fluid from the expandable compartment members [130]. Moreover, as the overall height is varied by supplying or sucking back of fluid from the expandable compartment members [130] of the toilet seat arrangement [104], no separate secondary toilet seats/ mechanisms are required for operations. Moreover, as overall height is varied by supplying or sucking back of fluid from the expandable compartment members [130] of the toilet seat arrangement [104], a cushioning effect is imparted to the toilet seat arrangement [104].
Another advantage of the present invention relates to the height restricting mechanism [118] of the toilet seat arrangement [104]. The height restricting mechanism [118] installed between the upper toilet seat member [112] and the lower toilet seat member [114], restricts the overall height of the toilet seat arrangement [104] to a maximum height. Accordingly, the height restricting mechanism [118] avoids chances of displacement due to increased overall height of the toilet seat arrangement [104].
Yet another advantage of the present invention relates to the heating unit of the toilet system [100]. The heating unit operates to heat the toilet seat arrangement [104] of the toilet system [100], by heating the fluid as received from the fluid reservoir [132] and supplied to the expandable compartment members [130] in the first configuration. As the heating unit is positioned within the control box [134], there exists no chances of direct exposure of the heating unit to the user. Accordingly, the safety of the user is ensured. Moreover, as the heating unit is a thermoelectric couple, it avoids a need of bulky coolant-based radiator arrangements for operations.
While the preferred embodiments of the present invention have been described hereinabove, it should be understood that various changes, adaptations, and modifications may be made therein without departing from the spirit of the invention and the scope of the appended claims. It will be obvious to a person skilled in the art that the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive.
