Abstract: A pop-up drain assembly for a sink has a drain stopper, a generally vertical control rod and a generally horizontal pivot rod. A connector device links the control rod to the pivot rod. The connector device has compressive-friction connectors that receive and hold the control rod and the pivot rod. The connector device preferably has a pair of opposing C-channels that define a hole therebetween, where the control rod is received through the hole and within an open C-shaped space in the C-channels, and preferably a two-prong fork, where the pivot rod is held in a compressive-friction fit between the prongs on the connector device. The drain stopper preferably has a dual-prong fork, and the pivot rod is received between the prongs on the drain stopper in a compressive-friction fit.

Abstract: Disclosed are various embodiments of a linkage assembly apparatus that comprise a spring clip that comprises a first end aperture, a second end aperture, and a connector aperture separated between a number of bending lines positioned along a length of the spring clip. The spring clip can be elastically deformed for insertion of a lift rod through the first end aperture and the second end aperture. The linkage assembly can also include an upper linkage rod that extends in a direction longitudinally. The upper linkage rod comprises a socket at a first end and a snap-on connector at a second end. In addition, the linkage assembly includes a lower linkage rod comprising a ball disposed toward an end of the lower linkage rod and a slot that extends along a length of the lower linkage rod. The slot can be used for connecting with a ball rod of a pop-up drain body.

Abstract: A drain assembly for use with a faucet including a lift rod, a lever arm, and a coupler operably coupling the lift rod and the lever arm.

Abstract: A drain control assembly has a pop-up stopper controlled by a cammed actuating mechanism allowing the stopper to alternately seal and unseat from the drain opening by repetitively pressing down on the stopper. The seal seats against the structure housing the drain, such as a tub or sink basin and the like, so that a clean look and positive seal can be achieved. The assembly has integral catch basket that serves to both retain items fallen into the drain and removably mount the assembly to a support beneath the drain opening such that the assembly is firmed secured in place for controlling flow through the drain, but also can be dislodged so that the entire assembly can be removed and items in the catch basket can be retrieved. The assembly can then be reinstalled by simply inserting it down into the drain. A method of use is also disclosed.

Abstract: A control is provided adjacent an overflow of a bathtub or sink. It both remotely controls operation of a basin bottom drain, and provides an option of shutting off flow through the overflow. Rotation of a handle of the control controls the bottom drain, and axial movement of the handle controls flow through the overflow. For example, a clicker-type pop-out valve can control overflow flow. Slot and projection structures restrict use of the overflow shutoff when the drain is not closed, and/or in some circumstances even when the drain is closed.

Abstract: A pop-up drain stopper linkage assembly includes a lift rod, a connecting bar, a pivot rod and a drain stopper. The bottom end of the lift rod forms an engagement part. 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: The device has a housing (5) which comprises an opening (4) in which a button (15) is fixed on a receiving part (8) mounted movably in the housing (5). A fitting aid (36) is provided, with which the button (15) may be introduced into the opening (4) in the housing (5) and positioned in a recessed manner therein as well as being fixed to the receiving part (8). Sets of teeth (23, 27) on the receiving part (8) and on the button (15) enable simple and depth-adjustable fixing of the button (15) to the receiving part (8).

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: 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: An improved linkage assembly for a pop-up drain stopper assembly includes an elongated connector bar having a plurality of apertures adjacent both its upper and lower ends. The assembly also includes a stem having a J-shaped portion of its lower end that is received within a select aperture. A lever arm is received within an aperture adjacent the lower end of the connector bar, the opposing end of which is attached to a drain stopper. The linkage assembly may be quickly and conveniently adjusted or dismantled with minimal effort.
