Abstract

A drain cleaning apparatus includes a handle and a clog-catching member detachably connected to the handle. Wings, barbs or hooks project radially from the clog-catching member. The wings, barbs or hooks provide an angled projection that catches and holds a clump of debris in a drain pipe for pulling the clump out and unclogging the drain. Different end tools can be removably connected to a clog-catching member or to a smooth extension member to provide multifunctionality. The handle, clog-catching members, smooth extension members and tools can be connected together using a quick-connect connector, such as a snap fastener, a keyhole fastener or a side-release buckle, or a threaded connector. In addition to drain cleaning, the apparatus can be fitted with tools such as a magnet, grabber, light, camera and/or video for retrieval of objects and inspection of a space that is difficult to view directly.

Claims

1. A drain cleaning apparatus, comprising:

a handle having opposing ends and a gripping portion, wherein one of the ends comprises a handle connector; and

a clog-catching member having a body that has a length, a proximal end, a distal end, and a plurality of wings, prongs, barbs or hooks, wherein the proximal end has a proximal-end connector that is detachably connected to the handle connector, wherein the plurality of wings, prongs, barbs or hooks project radially from the body with respect to the longitudinal axis of the body, and

wherein each of the handle connector and the proximal-end connector has at least one generally circular hole and a longitudinal slot extending from the circular hole, wherein each of the handle connector and the proximal-end connector has at least one stud, and wherein the stud is received in the longitudinal slot.

2. The drain cleaning apparatus of claim 1, wherein the distal end of the clog-catching member has a tool connector, further comprising a tool having a mechanical device and a member connector that is detachably connected to the tool connector of the clog-catching member.

3. The drain cleaning apparatus of claim 2, wherein the mechanical device of the tool is selected from the group consisting of a pointed element, a rounded element, a hemispherical element, a barbed element, a barbed spear, a spear with a plurality of barbs, a spear comprising a plurality of arrowheads, a retractable spear with a plurality of barbs, a helical spear with a plurality of barbs, a helical spear that can rotate and has a plurality of barbs, a harpoon, a harpoon that has a plurality of fish hooks or J-hooks, a pusher/scraper, a puller/scraper, a brush, a magnet, a corkscrew, a coiled spring, an element with an adhesive, a wisk, a hook, a light, a camera, a video camera, a video camera and light assembly and an assembly that includes a video camera, a light and wireless transmission components.

4. The drain cleaning apparatus of claim 1, further comprising means for locking the handle connector and the proximal-end connector together.

5. The drain cleaning apparatus of claim 4, wherein the distal end of the clog-catching member has a tool connector, further comprising a tool having a mechanical device and a member connector that is detachably connected to the tool connector of the clog-catching member.

6. The drain cleaning apparatus of claim 5, wherein the mechanical device of the tool is selected from the group consisting of a pointed element, a rounded element, a hemispherical element, a barbed element, a barbed spear, a spear with a plurality of barbs, a spear comprising a plurality of arrowheads, a retractable spear with a plurality of barbs, a helical spear with a plurality of barbs, a helical spear that can rotate and has a plurality of barbs, a harpoon, a harpoon that has a plurality of fish hooks or J-hooks, a pusher/scraper, a puller/scraper, a brush, a magnet, a corkscrew, a coiled spring, an element with an adhesive, a wisk, a hook, a light, a camera, a video camera, a video camera and light assembly and an assembly that includes a video camera, a light and wireless transmission components.

7. The drain cleaning apparatus of claim 1, wherein the handle has the shape of the capital letter “

T”

.

8. The drain cleaning apparatus of claim 1, further comprising a guide element that projects from the body of the clog-catching member for guiding the clog-catching member through the drain pipe as the clog-catching member is retracted from the drain pipe.

9. The drain cleaning apparatus of claim 8, wherein the guide element comprises a pair of opposing guide wings that have guide edges, wherein lines lying on the guide edge of each guide wing intersect to form a “

V”

shape that points toward the proximal end of the clog-catching member.

10. The drain cleaning apparatus of claim 1, wherein a magnet is embedded in the body of the clog-catching member or near or in its distal end.

11. A drain cleaning apparatus, comprising:

a handle having opposing ends and a gripping portion, wherein one of the ends comprises a handle connector; and

a clog-catching member having a body that has a length, a proximal end, a distal end and a plurality of wings, prongs, barbs or hooks that project radially from the body with respect to the longitudinal axis of the body, wherein the proximal end has a proximal-end connector that is detachably connected to the handle connector, wherein at least one of the proximal-end connector and the handle connector comprises a receiving element having a generally circular hole and an adjoining slot for receiving a stud formed on a cooperating one of the handle connector and the proximal-end connector, wherein the stud has a shank portion and a head portion, wherein the head portion is passed through the circular hole and the shank portion is slid into the adjoining slot for fastening the stud to the receiving element.

12. The drain cleaning apparatus of claim 11, further comprising means for locking the stud into engagement with the receiving element.

13. The drain cleaning apparatus of claim 11, wherein the distal end of the clog-catching member has a distal-end connector, further comprising a tool detachably attached to the distal-end connector, wherein the tool is selected from the group consisting of a clog-catching element, a pointed element, a rounded element, a hemispherical element, a barbed element, a barbed spear, a spear with a plurality of barbs, a spear comprising a plurality of arrowheads, a retractable spear with a plurality of barbs, a helical spear with a plurality of barbs, a helical spear that can rotate and has a plurality of barbs, a harpoon, a harpoon that has a plurality of fish hooks or J-hooks, a pusher/scraper, a puller/scraper, a brush, a magnet, a corkscrew, a coiled spring, an element with an adhesive, a wisk, a hook, a light, a camera, a video camera, a video camera and light assembly and an assembly that includes a video camera, a light and wireless transmission components.
