Abstract
The invention relates to an improved remotely operated plug assembly (13) of the type with a pop-up plug (13) and cabling (14), wherein the inter-engaging means and the means for retaining the plug (13) in the sink waste unit (11) and in the closed position are circumferential. This allows the free movement of fluid from the plug (13) to the sink waste unit (11). The improvement relates to the use of common elements for both the inter-engaging means and the retaining means so that the one movable pin (34) acts in both the inter-engagement of the plug (13) and the sink waste unit (11), and the retention of the plug (13) within the sink waste unit (11) and in the closed position.

An improved remotely operated plug assembly for a sink or basin with a drain, said plug assembly including:
- a sink waste unit secured within said drain, which sink waste unit includes a drain pipe;
- a plug movably and releasably secured within said drain, said plug including a spring means, and an inter-engaging means, said plug having a closed top and sides with holes formed therein, wherein said plug is movably secured within the drain by said inter-engaging means which permits vertical movement of said plug within said drain, between an opened and a closed position and vice-versa, but which does not permit the removal of said plug from said drain under ordinary operating conditions, and said spring means serving to bias said plug to the open position, said open position being a position in which said holes are open to said sink or basin, and said closed position being a position in which said closed top is substantially flush with the top of said sink waste unit;
- an opening mechanism to move the plug from the closed position to the open position, said mechanism being situated remotely from said drain and plug and connected by cabling to a retaining mechanism, said opening mechanism including an opening means to move and retain one end of said cabling;
- said retaining mechanism, to keep said plug in the closed position, includes spring-biased means to release said retaining mechanism to allow said plug to move to the open position;
- means to allow the plug to be physically removed from said drain and replaced therein;
- wherein
- the plug is capable of movement between an open and a closed position by manual depression of said plug, and between a closed and an open position by operation of said remotely placed opening mechanism to release the retaining mechanism via the cabling;
- and
- said inter-engaging means and said retaining mechanism have common elements which are circumferentially situated within and about said drain pipe, and wherein one element of said retaining mechanism is the said one end of said cabling of said opening mechanism.
A plug for a sink or basin with a drain, said plug being remotely operated and being movably and releasably secured within a drain pipe, said sink waste unit including:
- a plug with a closed top and sides with holes formed therein, said plug being movably secured within the drain by an inter-engaging means which permits vertical movement of said plug within said drain, between an opened and a closed position and vice-versa, but which does not permit the removal of said plug from said drain under ordinary operating conditions, and which incorporates spring means to bias said plug to the open position, said open position being a position in which said holes are open to said sink or basin, and said closed position being a position in which said closed top is substantially flush with the top of said sink waste unit;
- an opening mechanism to move the plug from the closed position to the open position, said mechanism being situated remotely from said drain and plug and connected by cabling to a retaining mechanism, said opening mechanism including an opening means to move and retain one end of said cabling;
- said retaining mechanism, to keep said plug in the closed position, includes spring-biased means to release said retaining mechanism to allow said plug to move to the open position;
- means for enabling the plug to be physically removed from said drain and replaced therein;
- wherein
- the plug is capable of movement between an open and a closed position by manual depression of said plug, and between a closed and an open position by operation of said remotely placed opening mechanism to release the retaining mechanism via the cabling;
- said inter-engaging means and said retaining mechanism have common elements which are circumferentially situated within said drain pipe and about said drain pipe, and wherein one element of said retaining mechanism is the said end of said cabling of said opening mechanism.
