The upper end of the connecting bar has an engagement groove for the engagement part of the lift rod being engaged and fixed, and the connecting bar has a plurality of holes spaced apart a distance away from the engagement groove. The second end of the pivot rod connects to the drain stopper and a section adjacent the first end has a plurality of fixed portions for tying in with the hole of the connecting bar, and each of the fixed portions and any one of the holes are capable of being passing through and positioning with each other. Thereby, the pop-up drain stopper linkage assembly can be quickly and conveniently assembled with reliable linking effect.

Abstract: A wash basin drain structure includes a tightening assembly, a control rod assembly, a drain pipe, and a plug. A threaded top ring of the fastening assembly relative to a threaded annular seat is screwed reversely to push an anti-leakage washer of the drain pipe upward, so that the threaded top ring and a washer are against the bottom of the wash basin and resilient portions of the resilient ring engages with a non-slip portion of the drain pipe. When a threaded fixing member in a threaded hole of a fixing seat of the control rod assembly is screwed inward, the end of the threaded fixing member will hold against the body of the drain pipe and pull an inner pipe portion of the fixing seat to seal and engage with an insertion hole of the drain pipe. A magnetic end head of a link rod of the control rod assembly is attracted to connect with a magnetic portion of a plug body of the plug to act as a lever. The present invention can be assembled with ease.

Abstract: A conduit for communication of a pressurized water or fluid supply to a counter top appliance above a sink having a faucet providing water to the sink. The device features an elongated rod having an axial passageway for communication of a fluid when engaged through the drain rod aperture of a faucet. The rod has an exterior circumference sized to translate in the aperture and operate the drain closure apparatus on the sink. A pulsating dental cleaning appliance or water dispenser or knob are engageable to the top end of the rod which is adapted on a bottom end under the sink to engage with a pressurized fluid supply. The device may be provided for retrofit through existing faucets by replacing the drain rod, or with new faucets to provide a route for pressurized fluid above a counter top without having to drill holes in the counter top.

Abstract: A solenoid activated bathtub drain closure is associated with the bathtub having a bottom with a drain opening therein. A vertically movable drain stopper is mounted over the drain opening. A drain pipe is connected to the drain opening and is conventionally positioned below the drain opening. A solenoid having a movable plunger is located outside the drain pipe and is preferably mounted on the drain pipe. Linkage is secured to the plunger and extends from the plunger into the drain pipe and terminates at an inner end underneath the drain opening. The linkage is so configured that when the plunger is moved by the solenoid from a first position to a second position, the inner end of the linkage will engage the stopper and raise it with respect to the drain opening to permit fluid in the bathtub to flow by gravity.

Abstract: A drain valve 1 comprises a body 10 having a cylinder portion 11 and a branch portion 12, to which are mounted a plug 30 constituting a valve seat and a hose joint 70. A poppet 50 constituting a valve means is slidably inserted to the plug 30. An operating device 100 mounted to said branch portion 12 and comprising a movable shaft 120 is used to open and close the valve by operating said poppet 50 via an operating rod 160.

Abstract: A drain assembly mountable in a drain opening of a wash basin includes a movable stopper guide that can be used during installation to align the drain flange to the drain body from above the sink. The stopper guide supports at an upper end a stopper for closing the drain opening. The stopper guide has an axial opening accommodating an axial fastener joining the drain flange and drain body to the basin. The stopper guide also has downwardly extending legs defining an axial slot extending from the axial opening for accommodating cross-members extending laterally between each of the drain flange and drain body. The drain flange can be aligned to the drain body by engaging the drain flange cross-member and rotating it as needed. A method of installing a drain assembly to a basin is also disclosed.

Abstract: An “Electromatic Pop Up Drain” for electronically raising and lowering the pop up drain plug in lavatory sinks. The “Electromatic Pop Up Drain” has infrared sensors as a triggering device, ac-dc electric motor as the actuating device, positioning and connective linkage. The user actuates the drain plug by passive hand motion detected by the infrared sensors. This detection device triggers a sequence of events that leads to the closing of the drain plug. A second detection of hand movement by the infrared sensors cause the drain plug to open allowing for the water or liquid to drain freely from the sink.

Abstract: A wastewater drain control for fluid compartments has a waste water discharge port in the bottom thereof and in communication with a vertical drain pipe. A valve seat element is in the pipe below the port and has an inclined annular valve seat surface and a center opening. A spherical valve element has a diameter greater than the center opening in the valve seat surface and is adapted to close the center opening to fluid flow when dwelling on the valve seat element above the center opening. A valve stem is rigidly secured by an upper end to the spherical valve element. The lower end extends downwardly through the center opening and terminates in a lower end. This lower end is connected to a linkage assembly which extends through a seal element in the vertical pipe and extends to a remote location accessible in the environment of the fluid compartment.

Abstract: The pop up lavatory plug comprises a body which depends from a head and has a trailing connector. The connector is elongate and has a linear array of bores therein. The head has a cavity in a top surface thereof which engages an overcap. Extending downwardly into the plug body from within the cavity is a slot by means of which an overcap assembly can be floatingly engaged to the plug in place of the overcap when it is desired to cover a visible flange of a drain assembly rather than merely selectively sealing an orifice of the drain assembly as is accomplished when the overcap is used.

Abstract: A drainage fixture for a sanitary device, such as a sink, lavatory, or bathtub having a drainage socket with a drain hole includes a drainage funnel and a stationary disk inserted into the drain hole of the sanitary device. A plunger, including a plunger head and a guide element, for closing the drain hole is positioned under the stationary disk so as to be movable between a closed and an open position. The drainage funnel has an upper rim portion forming a sealing collar for the plunger head in the closed position. The upper rim portion is recessed in the drain hole so as to provide space for a longitudinal movement of the plunger head between the closed and the open positions.
