Description

Title of the invention A toilet flush button

Field of the Invention

The current invention relates to a flush button device for a toilet. In particular, the current invention is directed towards a removable flush button device for use in operating a dualflush button present on a conventional toilet.

Background of the Invention

Increasing environmental awareness together with the rising cost of water and concerns over water conservation has led to an increase in the use of toilets with a dual-flush button assembly. This assembly provides the user with the option of manually selecting the water volume of each toilet flush by allowing a partial flush or a full flush of the toilet contents. This action is in contrast to traditional toilets that have only one flush mode, which use a lot of water. A toilet containing a dual-flush system comprises a large hole, or trapway, at the bottom of the toilet bowl that is larger than that of a standard single-flush toilet. This design allows the dual-flush toilet to use gravity to flush the toilet contents by allowing the water to move fast enough to carry away the contents. Consequently, as no siphoning action is used the dualflush system requires less water per flush compared with standard single-flush toilets.

In general, a dual-flush button assembly comprises a housing having two separate button surfaces for the user to operate; one for each flushing option. Pressing the partial-flush button surface moves the button linearly to activate a partial flush. Pressing the full-flush button surface rotates the button to activate a full flush. In a typical assembly, a member is located beneath the surface of the button, which moves and pivots with respect to the assembly when the full flush portion is engaged, thereby allowing the full contents of the toilet bowl to be flushed.

One disadvantage with such dual-flush systems is that children, the elderly or people with certain physical disabilities, can often find it particularly difficult to effectively operate the dual-flush button as a certain amount of pressure needs to be applied to the button(s) in order for it to operate successfully.

The current invention serves to obviate this problem by providing a removable flush button device to assist the user with operating a conventional dual-flush button on a toilet. The current invention also provides fun feedback to a child by indicating via a sound module that they have successfully flushed the toilet. This feedback can assist with toilet training a young child.

Detailed Description of the Drawings

The invention will be more clearly understood from the following description of the following embodiments thereof, given by way of example only, with reference to the accompanying drawings as described above. Embodiments of the current invention are described below. The invention is not intended to be limited by these examples.

Dual-flush buttons on conventional toilets are often cumbersome and difficult to operate as they require a certain amount of physical strength to be activated successfully. The current invention serves to alleviate this problem by providing a removable flush-button device that can be retrofitted to any conventional toilet having a dual-flush button system. The device assists a user, who may be having difficulty due to physical weakness, to flush the toilet successfully.

The device of the current invention achieves this by providing a button which serves to increase the surface area of the conventional dual-flush button already present on the toilet. Due to its size and the fact that it protrudes from the housing, the button is easier to access compared with the conventional dual-flush button present on the toilet cistern. This allows the user to activate the button with the palm of their hand or their entire hand, thereby using more force and allowing it to be activated successfully. This is in contrast with a conventional dual-flush button which is recessed when pressed so can activated only by a single finger or by two fingers.

As the device of the invention is easy to install and is also detachable, it can be removed from the toilet cistern with ease, if necessary, depending on the user and easily reinstalled when required. Thus, the device is particularly useful for families with very young children who may not require the device to be continuously present and in use. The device is also useful for the elderly or people with certain physical disabilities.

It will be appreciated that the device is engageable with any surface of the toilet cistern that comprises a dual-flush button.

Figure 1 illustrates a front view of the device of the current invention. The device as illustrated in this Figure is in a non-active position, i.e. the button has not been pushed by a user. As shown, the device comprises a housing 1 having a button 2 protruding upwards from an opening in the surface of the housing 1. The housing 1 is substantially semi-spherical in shape from the illustrated angle. However, it will be appreciated that the housing can be of any shape, for example, a square or a triangle. The button 2 is cylindrical in shape with a curved top surface. However, again, it will be appreciate that the button can be of any shape that functions accordingly, for example, a rectangle. The underside of the housing has three suction cups 3 for retaining or fixing the device in the correct position on the toilet cistern such that the device is substantially aligned with the dual-flush button on the cistern. Any retaining device known in the art could be used and the structure of the retaining device can be varied as desired. For example, the retaining device may be screws, fabric hook and loop fasteners or double-sided tape or any known adhesive.

Figure 2 illustrates a side elevation of the device of Figure 1. As shown, the device comprises a housing 1 having a button 2. In this view, two of the three suction cups 3 are present.

Figure 3 is a back view of the device of Figure 1. As shown, the device comprises a housing 1 having a button 2 protruding upwards from and away from within the housing 1. The underside of the housing has three suction cups 3 for retaining the device on the cistern of a toilet.

Figure 4 illustrates an aerial view of the device of the current invention. As illustrated from this aerial view the shape of the housing 1 is triangular in shape with curved corners 4 when viewed from this angle. However, it will be appreciated that any shape could be used. The curved edge of a suction cup 3 protrudes from the underside of the housing at each curved corner 4.

Figure 5 illustrates a view of the underside of the device of Figure 4. As illustrated the shape of the housing 1 is triangular in shape when viewed from this angle. Each corner of the triangular housing 4 has a suction cup 3 of a circular shape. The outermost side edge of the suction cup 3 protrudes over from the edge of the housing away from the centre of the housing. Substantially at the triangular centre of the underside of the housing 1 is the underside of the button assembly 5. The underside of the housing is attached to the top surface of the housing by four screws 12. On either side of the underside of the assembly 5 is a plurality of sound holes 6 functioning to project the sound more efficiently from the device. As can be seen from Figure 5, the underside of the assembly comprises an outer circular band 7. This outer circular band 7 does not move relative to the housing in operation and is structural in function. The surface of the outer circular band 7 slopes inwards from its outer edge to its inner edge towards the centre of the assembly 5. This is clearly seen from the perspective view of Figure 7. The underside of the assembly 5 also has an inner circular band 8 from which the actuating member moves downwards in a linear direction away from the housing when activated. The inner circular band 7 does not move relative to the housing. In the centre of the underside of the assembly 5 is the actuating member 9. In cross sectional view, the actuating member is cruciform in shape comprising four arms 10. The innermost edge of the circular band 8 comprises rectangular slots 11 into which the arms 10 of the actuating member 9 slot and move along. After installation by the user, the bottom surface of the actuating member 9 is aligned with the top surface of the dual-flush button present on the top of the cistern of a standard toilet with a dual-flush system (not shown). In use, the user presses the button of the current device which engages and drives the actuating member, out of an opening in the housing downwards in a liner direction away from the underside of the housing. As the actuating member 9 is aligned with the dual-flush button it presses the dual-flush button of the toilet cistern, thereby activing the button and flushing the toilet contents. After the dual-flush button is pressed down and activated, the actuating member and the button will both return to their original positions. The movement of the cistern’s dual-flush button, pushes the actuating member and hence the button member back to their non-active or starting positions. Hence, with the device of the current invention, the user can achieve the flushing of the toilet contents easily.

Figure 8 illustrates a user installing the device of the current invention onto a toilet cistern 13. As can be clearly seen from this figure, the actuating member 9 has been activated by the flush button 1 and is protruding outwards from an opening in the housing 1. The user has aligned the bottom surface of the actuating member 9 with the dual-flush button 14 on the cistern of the toilet 13. Once aligned the device will be level on the surface of the toilet cistern 13 such that each suction cup attaches and retains the device in place.

Figure 9 is a cross sectional view of the device of the current invention. In this embodiment, no sound activating member is present. As illustrated, the device comprises a housing 1 of button 2. The button is substantially hollow. The button comprises an actuating member 9. The button is in a non-active state, i.e. it has not been activated by a user and is thus protruding from an opening in the surface of the housing. As can be seen from this Figure, along the lower outer perimeter of the flush button, internal to the housing, is a protruding ridge 15, which functions to retain the flush button in the housing in its first position. Two of the three suction cups 3 on the underside of the device are seen in this Figure. The upper surface of the actuating member also comprises a protruding ridge or lip about its perimeter to retain the member in the housing. The housing comprises a number of internal ribs 16.

Figure 10 illustrates a perspective view of the device of the current invention in an active position, i.e. the button has been pushed by the user and has moved downwards into the housing with only the raised curved surface of the button remaining on the outside of the housing. The flush button 2 has pushed the actuating member 9 downwards through an opening in the underside of the housing such that at least part of the actuating member protrudes outwards from the housing. The actuating member is cruciform in cross-section.

Figure 11 illustrates an alternative embodiment of the device of the current invention wherein the device comprises a sound activating member 18. The sound activating member 18 emits a noise when the device is activated. The sound activating member 18 is activated when the button is pressed. The flush button activates the sound activating member 18 when it is pressed by the user, by pushing sound activating member 18 downwards towards the actuating member 9. In this embodiment, the sound activating member 18 is an OEM sound chip in a plastic case. When the button is pressed by the user this causes the sound activating member 18 to emit a noise. The sound activating member 18 comprises a housing having two plastic mouldings, a first upper moulding and a second lower moulding, that slide relative to each other. The second lower moulding having side edges being slidable within and configured to be encased by the side edges of the first upper moulding. The sounder is within the housing. When the actuator is pressed the first upper moulding slides downwards towards the second upper moulding and the second upper moulding slides upwards towards and within the first upper moulding. This movement compresses the housing causing the height of the sound housing to decrease and press the sounder. The sound activating member can be turned off, by twisting the first upper moulding causing it to rotate and slot into the second lower moulding, locking the two mouldings together and preventing them from sliding relative to each other and compressing, such that they are no longer capable of pressing the sounder. This movement can be actioned by a button on the housing. The switch may be an electronic switch. Alternatively, the user can access the sound activating member and manually rotate the upper moulding of the sound housing to turn it off. It will be appreciated that any sound activating member known in the art could be used in combination with the device of the current invention.

Figure 12 illustrates the device of claim 11 in an active position. In this Figure, the button 2 has been pushed by the user and has moved downwards into the housing 1 with only the raised surface of the button remaining on the outside of the housing. The flush button has pushed the actuating member 9 downwards through an opening in the underside of the housing such that at least part of the actuating member protrudes outwards from the housing.

Figures 13 to 15 illustrate another embodiment of the device of the current invention. This embodiment allows the two button surfaces, i.e. the partial-flush button and the full-flush button, of a convention dual-flush button to be selectively pressed as required. Figure 13 displays the device in a non-active position. Figures 14 and 15 display the device in an activate position.

As illustrated in Figure 13, the button 21 protrudes from the housing 22 through an opening 30 in a similar manner to Figure 1. However, in this embodiment, the button is separated into two parts (21a, 21b), a partial-flush button 21a and a full-flush button 21b. Each part of the button has an integrated actuating member 23a, 23b. The dual-flush button of the toilet comprises a housing 25 and a partial flush button surface 27a and a full flush button surface 27b. The underside 24a, 24b, of the actuating members 23a, 23b, is configured to be aligned with one of the two button surfaces 27a, 27b, of the dual-flush button of the toilet cistern 25. The device comprises suction cups 26 for retaining and aligning the device on the cistern of the toilet (not shown). As can be seen from this Figure, along the lower outer perimeter of the flush button, internal to the housing, is a protruding ridge 28, which functions to retain the flush button in the housing in its first position. The device comprises a number of internal ribs 29.

Figure 14 illustrates the device of Figure 13, wherein the partial-flush button 21a of the device has been activated by a user. As can be seen the user has pushed the button 21a which has caused it to move in a downward motion through an opening 30 on the surface of the housing 22. The underside 24a is in contact with the partial-flush button surface of the dual-flush button of the toilet and has pushed the button within the housing and activated the partial flush of the toilet contents. It will be understood that an equivalent action can be taken by the full-flush button 21b when activated by the user.

Figure 15, illustrates the device of Figure 13, wherein both the partial-flush button 21a and the full-flush button 21b have been activated by the user. As can be seen the user has pushed the button 21a and 21b simultaneously which has caused both buttons to move in a downward motion through an opening 30 on the surface of the housing 22. The underside 24a and 24b are in contact with their respective button surfaces of the dual-flush button of the toilet, pushing both button surfaces within the housing 25.

In a preferred embodiment (not shown), each portion of said button member comprises a sound module which is capable of emitting a sound when the button member is pushed or activated by a user. Preferably, the sound module of the first portion emits a different sound to the sound module of the second portion. In this manner, the user is told whether a partial or a full-flush has been successfully actioned.
