  • Patent number: 10301803
    Abstract: A push-type drain stopper is usable in a drain pipe that has a pivot rod port surrounded by a stub by sealing a rod that protrudes into the pipe through the stub. The stopper is pressed transversely into engagement with the rod, which is an anchor. The drain pipe has a drain flange that seals around a drain opening in a sink. If the flange becomes worn and unsightly or if one desires to change a color scheme for the sink, a cap that has a diameter greater than the drain flange hides the drain flange from sight. A retrofit kit includes the drain stopper, pivot balls sized to fit different pop-up drain assemblies, a rod that passes through the ball into the drain pipe, and a wing nut fixed to an end of the rod for tightening the rod against a stub cap.

  • Patent number: 9554556
    Abstract: An automatically refreshed water supply for pets is provided by diverting the water from the water supply of a toilet to a water dispenser accessible to the pet and returning excess water to the toilet. The water is diverted from the flush cycle of a toilet to an exterior dish which fills to a predetermined level and then overflows over the edge of the dish and then by way of channels into the toilet, retaining the water after the flush cycle is completed. Alternatively a mechanism can be provided for triggering the replacement water flow by sensing of the motion or weight of the pet. The system can be pet-triggered for the toilet flush and/or flow of replacement water to the pet dish, or continuous water flow as long as the pet is detected.

  • Publication number: 20140373262
    Abstract: A drain closure device for a vessel such as a bathtub or sink is provided. The drain closure device comprises a stopper fitted with a sealing gasket and equipped with track followers on a vertical post capped with a horizontal stopper, plus a flanged pipe emanating from said stopper that fits to the drainage hole in a vessel. The device is operable to be concentrically disposed with a hole in the bottom of the vessel. Rotation of the stopper causes travel of the followers on the stem to rise against the track cut into the interior of the flanged pipe. Resistance to closure when opened is provided by a terminal rest stop for each track follower on the upper part of the track. No springs, pins, or resistance seals are used. Reverse rotation of the stopper causes reverse travel of the followers back down the track to a low resting place located to effect closure of the horizontal stopper atop the flange of the pipe resting on the perimeter of the vessel hole.

  • Publication number: 20090126091
    Abstract: A utensil scrubber apparatus for use with a sink drain comprises an insert sized to tightly fit within a sink drain and having first and second portions. The first portion provides circular peripheral flange and a medial opening for allowing both liquids and solids to pass down through the insert and into the sink drain. The second portion is axially concentric with the first portion and extends downwardly, providing a tapered circular outer surface for tightly fitting within the sink drain. A plurality of resilient bristles upwardly extend from the top surface of the first portion in a position adjacent to the opening. The bristles are sized and arranged in such a way as to allow for a relatively easy means of dislodging food from a utensil. In the preferred embodiment, the insert contains a scenting agent for masking potentially unpleasant odors emanating from the sink drain.
