Wall mountable drain stopper

Abstract

A drain stopper includes a suction cup. The drain stopper is configured to block a drain opening and prevent water from entering the drain. The suction cup allows the drain stopper to be stored on a variety of surfaces, such as a vertical bathtub wall. In one form, the suction cup is on the bottom of the drain stopper and fits within the drain opening.

Description

BACKGROUND

The following disclosure relates to drain stoppers and methods for using and storing drain stoppers, and has particular application to drain stoppers and methods for using and storing drain stoppers where the drain stopper can be removably mounted to a surface, such as a wall or shower door.

Drain stoppers are constructed to plug, or otherwise block, a drain opening to prevent or minimize the flow of water down the drain. Normally, drain stoppers are easily removable to allow water to flow out of a container, such as a sink or bathtub, and into the drain when blocking the drain is no longer desired. Numerous types of drain stoppers are available, such as a drain plug, that is sized to fit into and plug the drain opening in a fashion similar to a cork plugging the opening of a bottle. Other forms of drain stoppers do not fit within the drain opening, but instead fit over the top of the drain opening and extend beyond the drain opening. Typically, such drain plugs and other drain stoppers are made from hard rubber, or other hard rubber-like materials. Other forms of drain stoppers are made from a soft rubber or soft rubber-like material, such as soft PVC or equivalent material. In some instances, such drain stoppers can be a soft rubber-like material that fits over the drain, with the water pressure causing the stopper to seal against the surrounding bottom of the container so that little, if any, water flows into the drain.

However, drain stoppers similar to the above types can be somewhat annoying to use because there is often not a good place to store these drain stoppers when they are not being used to block a drain. In some cases, the drain stopper includes a metallic ring in the top that is connected to a portion of a sink or bath tub by a chain that is similar to pull chains used on light sockets. Often such drain stoppers are stored by wrapping the chain over the tub faucet or another nearby fixture. Other times, drain stoppers are placed on a ledge of the tub or sink where it is used. Some people even place the drain stopper in a drawer or in a sink cabinet when it is not in use.

DETAILED DESCRIPTION

Referring to FIGS. 1-5 , a drain stopper 10 can be molded from a flexible and resilient material, such as thermoplastic rubber, soft PVC, an elastomer of the type sold under the trade name Santoprene, or silicone. In one form, drain stopper 10 can be one unitary piece molded from a translucent material.

Drain stopper 10 includes a body that can be in the form of a disk-like member referred to hereinafter as “disk” 12 having a bottom 14 and a top 16 . In one form, disk bottom 14 has a substantially concave surface. Alternatively, disk bottom 14 can have a substantially flat surface. In contrast, disk top 16 can have a substantially convex surface. However, in an alternative form, disk top 16 could be a substantially flat surface. In one form, disk 12 is larger than the opening of a drain with which it is to be used and blocks the drain when disk 12 is placed over the drain, thereby preventing water from entering the drain or minimizing the amount that enters the drain. In an alternate form, disk 12 is slightly smaller, or approximately the same size, as the size of the drain opening such that disk 12 can be inserted into the opening to block the drain.

A grip 18 can be formed on the disk top 16 to allow drain stopper 10 to be easily gripped. In one form, grip 18 has a maximum cross-sectional area (in a plane “P” perpendicular to line 5 — 5 of FIG. 3 ) that is approximately circular and has a circular profile when viewed from above (see FIG. 2 ). In one form, the cross-sectional area of grip 18 increases from disk top 16 toward plane “P”. Additionally, the cross-sectional area of grip 18 can increase from the grip top 19 toward plane “P.”

A suction cup 20 can be included with drain stopper 10 and can be located on disk bottom 14 . However, it is also possible that suction cup 20 could be located on the disk top 14 and may even form grip 18 . Suction cup 20 has a concave interior surface and is used to removably mount drain stopper 10 to a surface near a drain, such as a shower stall wall. Suction cup 20 can be an integral part of disk 12 or can be attached to disk 12 in any appropriate manner. If suction cup 20 is located on the disk bottom 14 , suction cup 20 can be made smaller than the drain opening that it would be used with to allow suction cup 20 to fit within the drain opening so that it does not interfere with disk 12 blocking the drain. In such case, suction cup 20 would normally be sized to be smaller than a standard size drain opening of the type with which the stopper 10 is intended to be used, such as a 4″ kitchen sink drain or a 1⅝″ drain.

Referring to FIGS. 6 and 7 , in use, the user holds grip 18 and inserts suction cup 20 into drain opening 22 . The body of drain stopper 10 blocks drain 22 so that water is prevented from entering, or minimizing the amount that enters the drain, thereby blocking drain 22 . In one form, disk bottom 14 contacts the portion of the surface of the container 24 (such as a bathtub, shower, or sink) that surrounds drain 22 , thereby blocking drain 22 . As water is added, the pressure of the water on the top of drain stopper 10 increases the force between disk bottom 14 and container 24 , thereby creating a better seal that blocks drain 22 .

In order to drain container 24 , the user holds grip 18 and removes drain stopper 10 from the area in close proximity to drain 22 , thereby unblocking drain 22 . When not in use, drain stopper 10 can be stored by using grip 18 to removably mount suction cup 20 to any appropriate surface, such as vertical surface 24 , which can be a portion of a sink, bathtub, shower, a nearby wall or a nearby door.

The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. While particular embodiments have been shown and described, it will be apparent to those skilled in the art that changes and modifications may be made without departing from the broader aspects of applicants' contribution. The actual scope of the protection sought is intended to be defined in the following claims when viewed in their proper perspective based on the prior art.
