The invention generally relates to a drain cleaning device. More particularly, the invention relates to a drain cleaning device used for cleaning drains by removing hair and other debris that is collected in the upper portion of the drain where stopper or strainer mechanisms and other obstructions occur or collected anywhere along the drain pipe down to the bottom elbow bends of the drain where hair and other debris has collected (e.g., in the drain trap).
Bathroom drains are clogged most often by hair that enters the drain and collects from the drain trap at the bottom up to the drain opening. Most frequently, the hair combines with sticky products such as soap, shampoo, and toothpaste and builds a “log-jam” of sorts where these drain obstructions catch the hair, and some settles in the drain trap. After sufficient amounts of hair have collected in the drain trap or around the upper opening, the water from the sink basin begins to drain noticeably more slowly, and eventually can completely block the water from draining. Drain chemicals, home remedies such as baking soda and vinegar and plungers are frequently used for these clogs, but often fail to dissolve or dislodge the hair clogging the drain. In extreme cases, the only remaining remedy is to disassemble the drain or use a device that can effectively reach, snag, and extract the hair (e.g., a drain snake).
Also, liquid or gel-based chemical drain unclogging agents can contain corrosive chemicals that may damage the drain structure. The drain cleaning chemicals may also cause health problems to those who handle the liquids or gels incorrectly. Another problem with chemical agents is that a significant portion of the chemical agent may flow past the hair-clog (for example, in the vertical portion of a bathroom sink drain) such that the chemical cannot effectively submerge the hair in order to completely dissolve it.
Therefore, what is needed is needed is a drain cleaning device for cleaning a bathroom drain or other type of drain that is capable of unblocking the drain of accumulated hair and other debris.
Accordingly, the present invention is directed to a drain cleaning device that substantially obviates one or more problems resulting from the limitations and deficiencies of the related art.

It is to be understood that the foregoing general description and the following detailed description of the present invention are merely exemplary and explanatory in nature. As such, the foregoing general description and the following detailed description of the invention should not be construed to limit the scope of the appended claims in any sense.
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
Throughout the figures, the same parts are always denoted using the same reference characters so that, as a general rule, they will only be described once.
An illustrative embodiment of a drain cleaning device is seen generally at 10 in
In the illustrative embodiment, with combined reference to
Advantageously, the hourglass-shaped portions 14, 18 on the handle section 12 allow a user to spin the device 10 comfortably. In the illustrative embodiment, one hand 38 is placed on the upper hourglass-shaped portion 14, and the other hand 40 on the lower hourglass-shaped portion 18 to spin the device 10. Spinning action is important to dislodging hair clogs that accumulate in the drain (and get wrapped around drain part like the stopper). The finger recesses 16 are used for pushing and pulling the device 10 up and down within the drain. The up and down movement is used for pushing the device 10 further into the drain, or pulling the clog up and out of the drain.
In the illustrative embodiment, as shown in
In the illustrative embodiment, the ribs 24 extend horizontally down the elongated rod section 20. The ribs 24 are tapered starting at the first end 26 of the elongated rod section 20 (e.g., starting at an approximately 3/16″ diameter) and taper down to a smaller diameter at the second end 28 of the elongated rod section 20 (e.g., ending at an approximately ⅛″ diameter). The ribs 24 add rigidity to the elongated rod section 20 of the device 10. Without the ribs 24, the small diameter portion of the device 10 would be flimsy, and would not have the required stiffness to manipulate the drain. When the device 10 is spinned by a user, the ribs 24 can also act as a brush that clears grime from the sides of the drain pipe. At the end of the ribs 24 is yet another tapered area. This distal tapered area is important for helping the device 10 maneuver over pipe joints. This tapered area also acts as a ledge so that the edge of the hook material strip 30 (e.g., made from the hook portion of Velcro®) does not get caught on drain parts when pulling the device 10 up and out of the drain.
Now, referring to
A fifth type of tip section 22″″ that may be used with the illustrative drain cleaning device 10, 80 will be described with reference to
In the illustrative embodiment of
In the illustrative embodiment, as shown in
In the illustrative embodiment, the injection-molded micro-hook elements 82, 84 may have a thickness T (see
In the illustrative embodiment, the injection mold for the device 10, 80 may be designed with interchangeable inserts. The inserts are installed into the mold and allow the device 10, 80 to be mass-produced in different styles without having to make new mold for each style of device 10, 80. For example, one mold insert will produce a round end on the device 10 (so that the hook material strip 30 may be bonded to the tip section). A different insert could be installed in the mold for molding plastic barbs or hooks on the end (e.g., as shown in
In
In one or more embodiments, the entire drain cleaning device 10, 80 is configured to be discarded after being used to remove the debris from the drain pipe 48. In other words, the drain cleaning device 10, 80 is disposable, and is designed for single cleaning of a drain. The used drain cleaning device 10, 80 with the collected debris can be safely and environmentally discarded. Then, a new drain cleaning device 10, 80 can be used to remove hair from another clogged drain.
It is readily apparent that the aforedescribed drain cleaning device 10, 50, 80 offers numerous advantages. For example, the drain cleaning device 10, 50, 80 effectively cleans a bathroom drain or other type of drain by unblocking the drain of accumulated hair and other debris. The drain cleaning device 10, 50, 80 is designed to be used as a do-it-yourself (DIY) upper drain cleaning device.
Any of the features or attributes of the above described embodiments and variations can be used in combination with any of the other features and attributes of the above described embodiments and variations as desired.
Although the invention has been shown and described with respect to a certain embodiment or embodiments, it is apparent that this invention can be embodied in many different forms and that many other modifications and variations are possible without departing from the spirit and scope of this invention.
Moreover, while exemplary embodiments have been described herein, one of ordinary skill in the art will readily appreciate that the exemplary embodiments set forth above are merely illustrative in nature and should not be construed as to limit the claims in any manner. Rather, the scope of the invention is defined only by the appended claims and their equivalents, and not, by the preceding description.
