Description

ADDITIONEL WEIGHT FOR FLUSHING VALVE
The invention relates to weight portion for a valve in a toilet cistern. Toilets or WCs have valve flushing devices. Types of flushing devices include flush handles with a siphon in the toilet cistern and push-button flush systems with a drop- valve or a flap-valve in the cistern. In the siphon type the siphon is used to refill the cistern when it has been emptied with a flush. The siphon includes a sealing diaphragm operating to lift the water in the siphon chamber and to start the flush, emptying the water from the cistern into the toilet pan. The diaphragm can wear and fail over time resulting in a failure to flush. In this situation it is not possible to flush but there is no leak of water from the cistern through the diaphragm to the pan.
Push button flush devices operate to raise a valve seal located at the bottom of the cistern. Common valve seal mechanisms include drop valves and flap valves. There is no lifting of water required, so very little force is required to break the valve seal at the bottom of the cistern and start the flush. No flush handle is required and a push button can be used. A push button operation is often the design of choice as it is space saving, attractive, compact in structure and provides a flush operation with very little effort.
The value seal may wear and break over time causing failure of the seal between the cistern and the toilet pan. Replacing the seal may need to be carried out a number of times during the lifetime of the toilet cistern. The present invention seeks to improve the existing push button toilet flush systems.
According to an aspect of the present invention there is provided a toilet cistern weight for a push button WC comprising: a collar and a retaining element; the collar extending at least partly about a recess arranged to receive a control element; wherein the retaining element acts to secure the toilet cistern weight about the control element and wherein the weight of the toilet cistern weight is in the range from 30 to 45 grams.

Valve flushing devices with the seal at the bottom of the cistern are prone to leaks as the level of water is always above the seal. If the seal is compromised then water will flow into the pan under the force of gravity and water will leak in a continuous manner into the pan until the seal is replaced. By providing an additional weight on the flush control element the sealing function of the valve seal is improved.
The weight of the toilet cistern weight is a selection appropriate for a range of toilet flush systems. The weight should be sufficient to ensure a seal is maintained between the cistern and the toilet pan when needed, but not one that would impede the users' ability operate the push button flush system. The valve should still be released and cause the toilet pan to flush by action and activation of the push button.

In an embodiment, the collar comprises a U-shaped body having arms extending about a said recess arranged to receive a control element, wherein the retaining element engages with at least one arm of the U-shaped body so as to act to secure the toilet cistern weight about the control element. Each arm in an embodiment comprises a connection portion suitable for engagement with the retaining element. The connection portion of an embodiment comprises an anchor element in the arm and in an embodiment the anchor element comprises a hole in the material of the arm. This means that the U-shaped body and arms can be connected with a retaining element and held in place on to the control element. Each arm of an embodiment comprises an anchor point for the attachment of a number of options of connection means. The connection portion provides flexibility in the design of the toilet cistern weight. In an embodiment the retaining element comprises a retaining wire having two ends, a first end of the retaining wire engaged and anchored at a connection portion of the first arm and a second end of the retaining wire engaged and anchored at a connection portion of the second arm. The wire is easy to manufacture or obtain from existing suppliers and it can be affixed to the each arm of the U-shaped body acting to secure the weight in position at the control member.
The retaining element in an embodiment can be an additional U-shaped body having arms extending about a recess arranged to receive a control element. In the
embodiment the arms of the additional U-shaped body engage with an anchor element of the first U-shaped body. In this embodiment a retaining wire is not needed as the arms of each U-shaped body provide anchoring elements and regions for connection together with the other U-shaped body. The U-shaped pieces can be connected without any additional connection elements, this leads to ease of manufacture and fitting.
In an embodiment the retaining element comprises a screw thread portion. No additional fixing means are required and the toilet cistern weight can be fixed to a control element by a screw connection. The screw connection may be made above or below the control element or may be fixed to an upper portion or to a lower portion of the control element.

Figure 7b is a perspective view of the toilet cistern weight of Figure 7a in use with a push button device control rod of Figure 2.
Figure 1 and 2 show conventional flush devices for toilet cisterns. Figure 1 shows a flush handle siphon A with active flush portion above the water line in a cistern. A drop valve B and a flap valve C are also shown with the water level in a cistern above the seal point 10. Figure 2 illustrates a drop valve with push button flush, the push button 1 10 is connected to a control element or rod (not shown) via a control cable 1 12. The control element acts to operate the seal 100. A button cap 1 14 is located over the push button 1 10. The button cap 1 14 includes features of an ergonomic design to compliment the user's finger or thumb. In use, a user activates the flush with force exerted on the push button 1 10 via the button cap 1 14. Pressure or force is transmitted from the push button 1 10 to the control element or rod or pin via control cable 1 12. The control element acts to move the seal 100 and to urge the seal 100 out of engagement with the base or cistern connection. In this way water passes from the cistern to the toilet pan. The cistern contents empties into the toilet pan while the seal 100 is open. On release the control element allows the seal 100 to reconnect with the base of the cistern and reform a sealed portion isolating the cistern from the toilet pan.
Figure 3 is a representative view of a seal 100 for a portion O being the connection of the cistern to the toilet pan. Seal 100 is operated by control rod 1 16. In addition a toilet cistern weight 1 18 is provided on the control rod 1 16. In a first embodiment the toilet cistern weight 1 18 comprises a collar 1 18 accommodated around the control rod 1 16. The arms of the collar weight 1 18 comprise the portions either side of a split or cut 1 19 in the collar 1 18. The material of the collar weight 1 18 in this embodiment is lead or other suitable material of a type having a low hardness value with the result so that it is soft and malleable. The arms may be separated and moved a distance apart from each other in order to be wrapped around the control rod 1 16. The arms of the collar weight 1 18 may then be joined and brought together so as to retain the collar weight 1 18 at the control rod 1 16. The arms act so as to urge the collar 1 18 to grip the control rod 1 16 and to be retained. The arms act as a retaining element in addition to any portion of the control rod 1 16 that may assist in the gripping for example, a structural detent or supporting shoulder portion or a roughened surface for increasing the grip of the collar 1 18 at the control rod 1 16.
The toilet cistern weight 1 18a of a further embodiment is illustrated in Figures 4a and 4b. Figure 4a is a perspective view and Figure 4b shows a plan view of the weight 1 18a. The weight 1 18a comprises a U-shaped body 120 and a retaining element 122. The U- shaped body 120 has arms 124 extending about a recess 126. The recess 126 is arranged so as to receive the control rod 1 16. The retaining element 122 is brought into engagement with the arms 124 of the weight 1 18a in a direction of movement as shown in Figure 4a. The retaining element 122 engages with one or more of the arms 124 in a manner so as to secure the toilet cistern weight 1 18a about the control element 1 16. The retaining element 122 comprises a retaining wire fixed in anchor holes 128 provided in the arms 124. The weight used here to ensure sealing with the connection from the cistern to the toilet pan is around 40g, 41 g has been found, during testing to be particularly effective. In an alternative embodiment a second U-shaped body 121 acts as a retaining element. Figure 5a shows U-shaped body 120 and U-shaped body 121 connected together around control element 1 16.
The arm 124 of U-shaped body 120 is provided with a coupling formation in the form of a hook 130. The hook 130 is curved in a first sense, out of the page as shown in the drawings. The arm 124 of U-shaped body 121 is provided with a complimentary coupling formation in the form of a hook curved 132 in an opposite sense, along the page and with a rotation of 90 degrees. The hook 130 is adapted to receive hook 132 and to thus join the U-shaped bodies 120, 121 together and to secure them in a rigid manner. The hooks 130, 132 are of complimentary formations so that they may engage with one another by hooking together, in order to mechanically couple the ends of the arms 124 of each U-shaped body 120, 121 . The hooks 130, 131 or other coupling portions may be present on both arms 124 of each U-shaped body 120.
Other examples of coupling formations include a male mechanical coupling formation in the form of a tongue at one end of the U-shaped body 120 and a complimentary female mechanical coupling formation, in the form of a slot, provided at another end of the U- shaped body 121. The slot is adapted to receive at least part of the length of the tongue, to form a mechanical coupling between the ends of the adjacent U-shaped bodies. In this way the weight is arranged and may be balanced around the control rod and on top of the seal component. In an alternative the weight may be located around the seal. Figure 6 illustrates a weighted portion 140 as a body that can be threaded onto a screw thread 142. In this embodiment the seal retains the weighted portion 140. The weighted portion 140 can be a collar located at the top of the cistern tube 150 or control rod as shown in Figure 6, or can be mounted as a collar and screw threaded portion 200 located around and at the seal (lower position in the cistern) as shown in Figure 7. Here the screw thread 142 acts so as to retain the weighted portion 140 at or within the control rod or cistern portion. The weight here used to ensure sealing with the
connection from the cistern to the toilet pan is around 30g, 32g has been found, during testing to be particularly effective. The present invention extends to a push button WC valve control element and a toilet cistern weight as hereinbefore described. A push button WC valve flush device comprising a push button valve control element, a valve seal and a toilet cistern weight as hereinbefore described is also envisaged.
