Abstract

A device which naturally floats in liquid or which when activated becomes such a device and is an integral part of or connected to a plug in a domestic bath or sink such that when there is excessive liquid the device applies a force to the plug or part of the plug so as to cause the plug to open or partially open thus releasing the excess liquid.

Description

SAFETY FLOAT This invention relates to a float which automatically causes a discharge of liquid if a storage vessel becomes too full.
It is well known that liquid containers such as a sink or domestic bath but including other liquid containers such as industrial storage of chemicals, oil etc can overfill.
Overflow devices or monitoring systems can not always cope with the situation which in reality requires the rapid removal of the excess liquid.
The present invention by the addition of a device which floats in liquid either as an integral part of a plug in the case of the domestic bath and sink or attached to the plug by means of the existing chain or some other device such as a separate chain forces the plug to be removed from the plug hole due to the excess liquid level. This releases the water through the open plug hole.
In the case of the domestic bath or sink a float consisting of a water tight container full of air for example a plastic moulded bottle or tube with a chain and hook can be connected to the existing sink or bath plug. A further chain can be attached from the float to the anchor point for the existing chain.
The length of the chains which can have a means of adjustment determines the hight in the bath or sink that the float rests when there is no liquid. When the liquid level rises and applies an upward pressure on the float, the chain connected to the plug tightens and eventually pulls out the plug.
Another option is for a new type of plug which contains a pocket of air. Under normal pressures caused with the liquid level at a certain hight the plug remains stationary. However under the excessive levels of liquid hight the plug would be forced to float to the surface.
The force creating the upward pressure i.e. the wish for the device to float is in this example air. The invention relates to a force causing the plug to rise since the device wants to float. This force can be created with a device that floats for other reasons for example it is a foam or a gas other than air but not restricted to these examples.
The float device having an upward force due to the presence of liquid can be configured in such a manner as to apply additional force for example the float can be attached to a lever which is attached to the plug or to a connecting device such as a chain or be an integral part of the plug so that the upward force of the float is increased through the lever so as to apply a greater force to remove the plug.
The float can apply the force to one side of the plug rather than the centre either with or without the additional force of a lever so as to more easily remove the plug. It could cause a small section only of the plug to open.
The float device can be as described a container of air or it can be a device which does not normally float but is activated by the liquid to become a device which would float. Examples include an air bag inflated only as required such as in the case of car air bags to protect the driver, life jackets which inflate on contact with liquid and subsequently float is another example but not restricted to only these examples.
A preferred form of this invention is a simple one piece plastic moulded item containing a pocket of air which causes it to float and apply an upward pressure to remove the plug from the plughole when the liquid level is higher than that required.

Claims (5)

1. A device which floats and as such applies a pressure to remove a plug from a plug hole in a domestic sink or bath when there is excess liquid thus releasing the liquid through the open plug hole.
2. A plug which contains a media which causes it to float such as a pocket of air which is sufficient in size to allow the plug to remain stationary up to a certain level of liquid but when the liquid becomes excessive the plug floats out of the plughole releasing the liquid through the open plug hole.
3. A one piece plastic moulded container of air which floats in liquid and either as an integral part of the plug or which applies a force to the plug causes the plug to rise to release liquid through the resultant open plug hole.
4. A device which floats such that an excess of liquid causes the floating device to apply a force to the plug or part of the plug to cause the plug or a section of the plug to open to release the excess liquid.
5. A device which floats and by means of a lever applies an increased force to partially open or completely remove the plug to release excess liquid.
