The present invention relates to hair straining devices.
Drain pipes, particularly those that service shower stalls, bathtubs, or sinks are often clogged by an accumulation of hair that is shed by users. The hair flows down the drain with the water and accumulates in the drain pipe to form a clog that prevents proper drainage. Existing straining devices to catch this hair are typically provided above the drain pipe opening in the floor of the shower stall, bathtub, or sink in view of the user. Such devices are unsightly in that the accumulated hair is visible to the user at all times. These devices also have limited effectiveness and are difficult to clean. Accordingly, it would be desirable to provide a straining device that avoids these and other problems.
A hair straining device for a drain is disclosed. In some embodiments, the device comprises a central element, a bottom seal element, and a pair of arms. The central element has a sidewall and a hollow core. The hollow core is interior of the sidewall. The sidewall has at least one sidewall opening in communication with the hollow core and extending through the sidewall.
The bottom seal element is connected to a bottom end of the central element. The bottom seal element extends radially outward from the central element. The bottom seal element has at least one bottom drain opening extending through the bottom seal element. The central element extends vertically from the bottom seal element.
The pair of arms extend laterally from the central element and are configured to at least partially support the central element relative to the drain. The at least one sidewall opening and the at least one bottom opening are sized and positioned to substantially prevent hair from flowing therethrough.
Numerous other advantages and features of the present invention will become readily apparent from the following detailed description of the invention and the embodiments thereof, from the claims, and from the accompanying drawings.
The following description is presented to enable any person skilled in the art to make and use the invention. For the purposes of explanation, specific nomenclature is set forth to provide a plural understanding of the present invention.
