Abstract
A drain closure device for a vessel having an interior surface and a drain hole defined in the interior surface. The drain closure device includes a drain plug configured to be telescopically received in the central throughshaft defined in the insert sleeve. The drain plug is moveable between a first contacted ceiling position and a second expanded, drain position. The drain plug includes a seal member that is attached to the first end and a connection member located on a second end. The connection member is configured to releasably engage with at least one lateral shoulder or a suitable lateral projection member associated with the drain opening when the drain plug the use position.
Claims21
A drain closure device for a vessel having an interior surface and a drain hole defined in the interior surface, the drain hole configured to communicate with a drain pipe, the drain closure device comprising:
- a drain plug configured to be telescopically received in the drain hole defined in the vessel, the drain plug moveable relative to the drain hole between a first sealed position and a second unsealed position, the drain plug including:
- an elongate drain plug body having a first end and an opposed second end;
- a seal member attached to an outer surface of the drain plug body at a location proximate to the first end and extending outward therefrom, the seal member configured to sealingly engage an associated surface of the vessel located proximate to the drain hole when the drain plug is oriented in the first sealed position;
- and
- a connection member located proximate to the second end of the drain plug body, the connection member configured to be releasably engage at least one lateral shoulder associated with the drain hole when the drain plug is in either the first sealed position or the second unsealed position, the lateral shoulder having a thickness and a width;
- and
- at least one movement mechanism configured on the drain plug relative to a drain opening, the movement mechanism to trigger translational movement of at least a portion of the drain plug relative to the drain opening, the movement mechanism to act on the drain plug such that the seal member is moved from the first sealed position to the second unsealed position.
A drain closure device for a vessel having an interior surface and a drain hole defined in the interior surface, the drain closure mechanism comprising:
- a drain plug configured to be telescopically received in the drain hole defined in the vessel, the drain plug moveable relative to the drain hole between a first sealed position and a second unsealed position, the drain plug including:
- an elongate drain plug body having a first end and an opposed second end;
- a seal member attached to an outer surface of the drain plug body at a location proximate to the first end and extending outward therefrom, the seal configured to sealingly engage an associated surface of the vessel located proximate to the drain hole when the drain plug is oriented in the first sealed position;
- and
- a connection member located proximate to the second end of the drain plug body, the connection member configured to be releasably engage at least one lateral shoulder associated with the drain hole when the drain plug is in either the first sealed position or the second unsealed position, the lateral shoulder having a thickness and a width, wherein the connection member of the drain plug has at least one lateral slot configured to engage the terminal end of the lateral shoulder, the lateral slot having a width greater than the thickness of the lateral shoulder, and wherein the connection member further defines an entry slot in angular communication with the lateral slot, the entry slot having a width greater than the width of the lateral shoulder;
- and
- at least one movement mechanism configured on the drain plug relative to a drain opening, the movement mechanism to trigger translational movement of at least a portion of the drain plug relative to the drain opening, the movement mechanism to act on the drain plug such that the seal member is moved from the first sealed position to the second unsealed position.
