Background Art

[0003] The present disclosure generally relates to the field of tools. The present invention particularly relates to a drain cleaner tool. Utility Model Content

[0004] One embodiment of the utility model relates to a drain cleaning tool, which includes a drum, an elongated tube and a cable lock assembly. The elongated tube extends from the drum along the longitudinal axis of the drain cleaning tube and includes an opening at the distal end away from the drum. The cable lock assembly is connected to the distal end of the elongated tube. The cable lock assembly includes a head portion, which has: a first end, which is positioned at the distal end of the elongated tube; and a second end opposite to the first end. The second end of the head portion includes an outlet opening. The cable lock assembly further includes an actuator, which is rotatably engaged with the head portion and extends along the longitudinal axis of the drain cleaning tool. The drain cleaning tool further includes a cable, which is stored in the drum and is configured to extend through the elongated tube and the head portion. The actuator can rotate around the longitudinal axis of the drain cleaning tool between an unlocked position and a locked position, in which the cable can move relative to the head portion and in which the cable is fixed relative to the head portion.

[0005] Another embodiment of the utility model relates to a drain cleaning tool, which includes a drum, an elongated tube and a cable lock assembly. The elongated tube extends from the drum along the longitudinal axis of the drain cleaning tube and includes an opening at the distal end away from the drum. The cable lock assembly is connected to the distal end of the elongated tube. The cable lock assembly includes a head portion, which has: a first end, which is positioned at the distal end of the elongated tube; and a second end opposite to the first end. The second end of the head portion includes an outlet opening. The cable lock assembly further includes an actuator, which is rotatably engaged with the head portion. The actuator includes an actuator channel extending along the longitudinal axis of the drain cleaning tool. The drain cleaning tool further includes a cable, which is positioned in the drum and is configured to extend through the elongated tube and the outlet opening into the drain. The actuator can rotate about the longitudinal axis of the drain cleaning tool between an unlocked position and a locked position. In the unlocked position, the longitudinal actuator axis is colinear with the longitudinal axis of the drain cleaning tool so that the cable can move in the actuator channel. In the locked position, the longitudinal actuator axis is parallel to the longitudinal axis of the drain cleaning tool but not colinear, so that the cable is pressed between the inner surface of the actuator channel and the inner surface of the elongated tube to lock the cable in the appropriate position.

[0006] Another embodiment of the utility model relates to a drain cleaning tool, which includes a body, a folding mechanism and a head portion. The body extends along the longitudinal axis of the drain cleaning tool and includes a passage extending through the body, an upper portion and a lower portion, and the upper portion has an opening connected to the passage. The folding mechanism includes a coupler, which is positioned between the upper portion of the body and the lower portion of the body. The folding mechanism further includes: a pipe, which is located in the coupler and connects the upper portion of the body and the lower portion of the body; and a pin, which is configured to engage the coupler. The head portion is coupled to the distal end of the lower portion of the body and includes an outlet opening. The drain cleaning tool further includes a cable, which is configured to extend through the passage of the body and the outlet opening of the head portion into the drain pipe. The drain cleaning tool is movable between an extended position in which the pin engages the connector to fix the position of the connector relative to the body so that the tube is compressed, and a collapsed position in which the pin disengages from the connector so that the tube expands and the length defined between the upper portion of the body and the lower portion of the body increases.

[0007] Another embodiment of the utility model relates to a drain cleaning tool, which includes a body, a folding mechanism and a head portion. The body extends along the longitudinal axis of the drain cleaning tool and includes a passage extending through the body, an upper portion and a lower portion, and the upper portion has an opening connected to the passage. The folding mechanism includes a coupler, which is positioned between the upper portion of the body and the lower portion of the body. The folding mechanism further includes: a pipe, which is located in the coupler and connects the upper portion of the body and the lower portion of the body; and a pin, which is configured to engage the coupler. The head portion is coupled to the distal end of the lower portion of the body and includes an outlet opening. The drain cleaning tool further includes a cable, which is configured to extend through the passage of the body and the outlet opening of the head portion into the drain pipe. The folding mechanism is movable between an extended position in which the pin engages the coupler to fix the position of the coupler relative to the body so that the upper portion of the body and the lower portion of the body are aligned along the longitudinal axis of the drain cleaning tool, and a folded position in which the pin disengages from the coupler to allow the lower portion of the body to rotate to a position in which the upper portion of the body and the lower portion of the body are not aligned along the longitudinal axis of the drain cleaning tool.

[0008] In a specific embodiment of the utility model, the support handle is adjustable and rotatable. In another specific embodiment, the support handle includes a curved shape that extends toward the drum and then bends toward the distal end. In such an embodiment, the end surface of the support handle generally faces in the same direction as the distal end of the drain cleaning tool. In another specific embodiment, the support handle is located above the center of gravity of the drain cleaning tool. In another specific embodiment, the support handle is located slightly forward of the center of gravity of the drain cleaning tool.

[0009] In a specific embodiment of the utility model, the rotating handle is foldable so that the size of the drain cleaning tool is reduced for storage. In this embodiment, the rotating handle forms a flat surface so that the drain cleaning tool can be stored in a manner that the outer surface of the rotating handle is located on a support surface (ground, table, etc.).

[0010] In another specific embodiment of the utility model, when the actuator is in the locked position, the through hole of the actuator deviates (i.e., is not aligned) from the opening at the elongated tube and / or the distal end and the passage extending through the end portion of the neck. When the actuator moves to the locked position, the deviation causes the size of the through hole to decrease, which in turn presses and / or pushes the cable between the wall of the actuator and the wall of the elongated tube, thereby locking the cable in place so that the cable is prevented from moving rotationally and / or axially. When the actuator is in the second unlocked position, the through hole of the actuator is in line with the opening at the distal end of the elongated tube, the drain cleaning tool, and / or the passage of the end portion, so that the cable can move freely rotationally and / or axially.

[0039] Referring generally to the accompanying drawings, various embodiments of drain cleaning tools are shown. As discussed herein, applicants have developed many improvements on drain cleaning tools. Compared to the drain snake tools discussed herein, many electric or manual drain snake tools include large drum portions and / or handles to drive the cleaning cable. Applicants believe that drain cleaning tools including small diameter drums without extended handles allow for use in compact spaces (e.g., under sinks, near walls or other sanitary appliances). In addition, applicants have designed a hose opening and a folding plug that together allow for easy cleaning and accommodating of dirty cables after using the drain snake.

[0040] Compared to the various drain augers discussed herein, many augers have an extended body or rigid portion, which may make it difficult to manipulate or carry the drain auger without causing damage (e.g., scraping against a wall, colliding with an object, etc.). The applicant believes that a drain auger including a folding mechanism having a flexible or foldable portion and a rigid portion that can be clipped to the auger body allows for easier transportation and storage. For example, an auger with the folding mechanism discussed can allow a functionally 6-foot auger to be folded and stored in a length of 3 feet to 4 feet. In addition, the applicant has designed a funnel portion with an opening to allow easy cleaning of the drain auger. In addition, the applicant believes that the longer sheath portion of the flexible end of the auger prevents accidental scratching or chipping of bathware (e.g., a ceramic toilet, a bathtub, etc.). The longer sheath allows the cable or coil to be completely nested or reside in the flexible end, which is very different from many augers in which the cable end or ball extends beyond the end of the auger, thereby causing the possibility of damage to the appliance.

[0041] refer to Figure 1 to Figure 2 , various aspects of a drain cleaning tool, shown as a drain snake 10, are shown. The drain snake 10 includes a drum 12, a drum cover 14, a handle 16, and a cable or coil 18. The drum 12 includes a first or lower portion 24 that is coupled to a second or upper portion 26. The drum 12 is at least partially positioned within the drum cover 14, specifically within an elongated tube or passage 15 that extends through the drum cover 14 and / or the handle 16. The drum cover 14 is used to protect the drum 12 and protect appliances (e.g., sinks, bathtubs, toilets, etc.) from damage (e.g., scratches, chips, etc.) caused by the rotating drum 12. The drum 12 is configured to rotate within the drum cover 14, thereby causing the cable 18 to rotate.

[0042] The drum 12 further includes a plurality of side extrusions 28 extending radially outward from the drum 12. The side extrusions 28 allow the user to grip the drum 12 and rotate the drum during drain cleaning. The drum 12 can rotate in a clockwise direction as indicated by arrow 46 and in a counterclockwise direction as indicated by arrow 48. When the drum 12 rotates, the cable 18 rotates, thereby allowing the cable 18 to move around a curve in the drain and also clean / unclog the drain. The cable 18 is formed of a flexible material and is stored in the drum 12 (e.g., wound on a reel) when the drain snake 10 is not in use. The cable 18 extends through the passage 15 and leaves the drum cover 14 and / or the handle 16 through an opening 17 at the end away from the drum 12, so that the cable 18 can extend into the drain. In a specific embodiment, the cable 18 includes a narrower cable portion 22 and an end portion or a ball portion 20, which can be used to break or retrieve objects or debris (e.g., hair) that cause obstructions in the drain or pipe. In other embodiments, the cable 18 may not include a ball portion or include another attachment tool at the distal end. In a specific embodiment, the length of the cable 18 is between 15 inches and 35 feet, specifically about 25 feet (e.g., 25 feet plus or minus 1 foot).

[0043] The cable 18 is fed through the drain snake 10, specifically through the drum 12, the drum cover 14 and / or the handle 16, along the longitudinal axis 21 of the drain snake 10. The cable 18 extends from the opening 17 in a first direction, along the longitudinal axis 21, into the drain pipe by linear movement. Similarly, when the cable 18 is moved linearly along the longitudinal axis 21 in a second direction opposite to the first direction, the cable can be retracted into the opening 17 and the passage 15. The handle 16 includes an internal finger or protrusion. When the handle 16 is actuated, the cable 18 is automatically fed through the drum cover 14 and out of the opening 17.

[0044] The drum 12 further includes a center surface 32 located on the upper portion 26. The center surface 32 is centered around the longitudinal axis 21, and the upper portion of the side extrusion 28 extends radially outward from the center surface 32. A cap recess 34 is defined within the center surface 32. An opening, shown as a hose opening 36, is centered around the longitudinal axis 21 and is defined within the cap recess 34. The hose opening 36 provides access to the interior of the drum 12 and is sized to receive at least a portion of a hose or tube. After using the drain snake 10, a hose can be placed in the hose opening 36 so that the drum 12 and the drain snake 10 can be cleaned when the water is drained. A handle recess 35 is at least partially defined within the center surface 32. The handle recess 35 extends in a substantially vertical (e.g., 90°±10°) orientation relative to the cap recess 34.

[0045] The drain snake 10 further includes a folding cap 38 configured to interface with the plug opening 36 through the cap recess 34, the handle recess 35, and the opening 36, respectively. The folding cap 38 includes a plug portion 40 extending away from the base 42. The base 42 is coupled to the handle portion 44. The handle portion 44 has a main axis oriented substantially perpendicular to the main axis of the base 42. The folding cap 38 is pivotally coupled in the handle recess 35. The folding cap 38 is movable between a first position in which the folding cap 38 blocks / obstructs the opening 36 and a second position in which the opening 36 is unblocked. When the folding cap 38 is in the closed position, the handle portion 44 is received in the handle recess 35, the base 42 is received in the cap recess 34, and the plug portion 40 is received in the opening 36, so that when the folding cap 38 is in the closed position, the drum 12 is sealed. The ability to seal the drum 12 after using the drain snake 10 allows the user to put the tool down while preventing debris (eg, drain clogs) or liquid on the cable 18 from escaping the drum 12 .

[0046] In a particular embodiment, a hook, shown as a rafter hook 30, is coupled to the drum 12. The rafter hook 30 allows the drain snake 10 to be easily stored (e.g., it can be hung in a garage, workshop, etc.). Figure 1 As shown, the drum 12 has a diameter shown as D1. The diameter D1 of the drum 12 allows the drain snake 10 to be used in compact spaces (e.g., under a sink, near a wall or other plumbing fixture) where other drain cleaning tools may be too large to comfortably use or install without damaging the wall or surrounding plumbing fixtures.

[0047] refer to Figure 3 to Figure 4 , various aspects of a drain cleaning tool, shown as a drain auger 110, are shown. The drain auger 110 includes a tip portion 112, a body 114, a cable or coil 115, and a handle 124. The cable 115 extends from the handle 124 through the body 114 and the tip portion 112 of the drain auger 110. The tip portion 112 is coupled to the body 114 at a first end 123. A second end 125 of the body 114 is opposite the first end 123. The tip portion 112 is formed of a flexible material (e.g., rubber, silicone, etc.). The flexible tip portion 112 allows for easier insertion into appliances such as toilets while also preventing accidental damage (e.g., chipping, scratching, etc.).

[0048] The end portion 112 is designed to include a long sheath 113. The sheath 113 includes a sheath opening 126. The size of the sheath 113 and the sheath opening 126 is determined to fully accommodate the cable 115, which further helps to prevent scratching the toilet bowl. Many augers include a sheath that cannot fully accommodate or surround the end of the cable, so that a portion of the cable extending outward from the auger is in a position that may scratch the toilet bowl during insertion and use of the auger. In a specific embodiment, the cable 115 includes an end portion or a ball portion that can be used to break through or retrieve objects or debris (e.g., hair) that cause obstructions in a drain or pipe. In other embodiments, the cable 115 may not include a ball portion or may include another attachment tool at the distal end.

[0049] The cable 115 includes a flexible portion 116, a rigid portion 118, and an angled portion 122. The end of the cable 115 including the angled portion 122 is coupled to a handle 124. The opposite end of the cable 115 extends through an elongated tube or passageway within the body 114 and the head portion 112 of the drain auger 110. The combination of the flexible portion 116 and the rigid portion 118 allows a user to fold the drain auger 110 so that the drain auger has a reduced length for storage and transportation of the tool. While the flexible portion 116 facilitates the folding of the cable 115, the rigid portion 118 ensures that the user can generate sufficient force to break through a drain obstruction.

[0050] To use the drain auger 110, the user inserts the head portion 112 into a plumbing fixture such as a toilet when the cable 115 is fully nested within the sheath 113. The user can then turn the handle 124 in a clockwise direction while pushing downward (e.g., toward the toilet) to move the cable 115 within the body 114 and out of the head portion 112 through the sheath opening 126, thereby extending the cable 115 into the toilet and the connected plumbing system where an obstruction may exist. If necessary, the handle 124 can be used to pull back and re-extend the cable 115 until the obstruction is cleared or removed.

[0051] Once the obstruction is removed, the cable 115 can be retracted from the plumbing system by pulling the handle 124 upward (e.g., away from the toilet). As discussed above, the drain auger 110 can be easily cleaned after use. The second end 125 of the body 114 of the drain auger 110 is connected to the funnel 120. The funnel 120 includes an opening or hose opening 134. The hose opening 134 is configured to receive at least a portion of a hose or pipe. The hose can be placed in the hose opening 134 of the funnel 120 so that when the water is released, any debris (e.g., drain obstruction) or liquid remaining in the drain cleaning process can be removed from the drain auger 110. The size of the funnel 120 and the hose opening 134 is determined to allow the hose to seal to the funnel 120 so that water will be forced through the body 114 and the end portion 112 during the cleaning process.

[0052] The drain auger 110 further includes one or more retaining components, shown as clamps 128. Each clamp 128 includes a connector 130 that extends at least partially around the body 114. Each clamp 128 further includes a pair of retaining arms 132 that are configured to grasp a portion of the cable 115. When the flexible portion 116 of the cable 115 is folded, the rigid portion 118 extends in a manner generally parallel to the body 114. When the rigid portion 118 is in this parallel position, the retaining arms can grasp and / or hold the rigid portion 118 and the cable 115 proximate the body 114, thereby reducing the overall length of the drain auger.

[0053] In a particular embodiment, the total or extended length of the drain auger is approximately 6 feet (e.g., 6 feet plus or minus 6 inches). In such an embodiment, the collapsed length of the drain auger 110 is defined as L1, and L1 is approximately 40 inches (e.g., 40 inches plus or minus 3 inches). As mentioned above, the ability to collapse the drain auger 110 results in an auger that is 3 to 4 feet in length when collapsed for transport and storage, which can be used as a 6-foot auger when used for drain cleaning.

[0054] Compared with the drain cleaning tool discussed herein, many traditional drain cleaning tools include a handle that protrudes downward so that the user holds the roller above their hand and / or wrist. The applicant's handle is designed to allow the handle to be positioned above the drain cleaning tool during use so that the roller is positioned below the user's hand and / or wrist. The handle is rotatable so as to allow the user to adjust and have an ergonomic shape. In a specific embodiment, the handle can rotate 360 ​​degrees so that the user can position and / or move the handle to a position suitable for using the drain cleaning tool. In a specific embodiment, the handle shape is curved and faces the end of the drain cleaning tool. In addition, the applicant's handle is located above the center of gravity of the tool and / or slightly in front of the center of gravity of the drain cleaning tool. The applicant believes that the described positioning of the handle relative to the center of gravity of the drain cleaning tool reduces the pressure on the user's wrist during the use of the drain cleaning tool.

[0055] In various embodiments, the drain cleaning tool includes a cable locking assembly. In contrast to the drain cleaning tools discussed herein, many conventional drain cleaning tools include a lock at the end of the tool (i.e., where the cable exits the tool neck). Applicant's cable locking assembly is positioned between the drum and the end of the tool. Applicant believes that the location of the locking assembly of the drain snake tool discussed herein prevents accidental actuation that would release the cable during use.

[0056] In a specific embodiment, the drain cleaning tool includes a rotating handle located on the back of the drum to allow the cable to be rolled up inside the drum after using the tool. The rotating handle is foldable (i.e., flipped down) to make the drain cleaning tool more compact for storage. Specifically, when the rotating handle is in the storage position, the rotating handle forms a flat surface so that the drain cleaning tool can be stored in an upright position.

[0057] refer to Figures 5 and 6 , various aspects of a drain cleaning tool, shown as a drain snake 210, are shown. The drain snake 210 includes a drum 212, a tube and / or neck 214, a rotating handle 216, a support handle 218, a cable or coil 224, and a cable lock assembly 220. In particular embodiments, the tube and / or neck 214 serves as a shield to protect the drum 212 and / or an appliance (e.g., a sink, a tub, etc.) from damage (e.g., scratches, chips, etc.) that may be caused by rotating the drum 212. The drum 212 includes a first or lower portion 239 coupled to a second or upper portion 219. The drum 212 is at least partially positioned within the neck 214, which surrounds an elongated tube or passageway 240 (i.e., a feed tube for the cable 224, see e.g., FIG. 1 ) that extends into and / or through the drum 212. Figure 8). In a particular embodiment, the elongated tube 240 is integral with the drum 212. In other words, the elongated tube 240 and the drum 212 are a single continuous and / or integral part, such that the elongated tube 240 and the drum 212 are permanently coupled and / or integral parts. In various other embodiments, the elongated tube 240 and the drum 212 are separate components that are coupled or connected (e.g., by fasteners, adhesives, etc.). The drum 212 is configured to rotate within the neck 214, thereby causing the cable 224 to rotate. The drain snake 210 further includes a tip or end portion 222 located at the distal end of the drain snake 210 (i.e., the end facing away from the drum 212). The end portion 222 includes a tip of the drain snake 210 having an outlet opening or hole 223.

[0058] refer to Figure 7 , the drum 212 can rotate in a clockwise direction as indicated by arrow 235 and in a counterclockwise direction as indicated by arrow 237. As the drum 212 rotates, the cable 224 rotates, allowing the cable 224 to move around a curve within the drain pipe and also clean / unclog the drain pipe. The cable 224 is formed of a flexible material and is stored within the drum 212 (e.g., wound on a reel) when the drain snake 210 is not in use. The cable 224 extends through the elongated tube 240 and exits the drain snake 210 and the neck 214 through the outlet opening 223 at the end away from the drum 212 so that the cable 224 can extend into the drain pipe. In a specific embodiment, the cable 224 includes: a narrower cable portion 226; and an end or ball portion 228 that can be used to break through or retrieve objects or debris (e.g., hair) that cause obstructions within a drain pipe or pipe (see, e.g., Figure 5 ). In other embodiments, the cable 224 may not include a bulb portion or include another attachment means at the distal end. In a specific embodiment, the length of the cable 224 is between 15 feet and 35 feet, specifically about 25 feet (e.g., 25 feet plus or minus 1 foot).

[0059] refer to Figures 5 and 6, feeding the cable 224 through the drain snake 210 along the longitudinal axis 221 of the drain snake 210, specifically through the drum 212, the neck 214 and / or the end portion 222. The cable 224 extends out from the outlet opening 223 in a first direction along the longitudinal axis 221 into the drain pipe by moving linearly. Similarly, the cable 224 can be retracted into the outlet opening 223 and the elongated tube 240 when moving linearly along the longitudinal axis 221 in a second direction opposite to the first direction. The rotating handle 216 is coupled to the rear side of the upper portion 219 of the drum 212. In other words, the rotating handle 216 is coupled to the rear surface of the drum 212. The rotating handle 216 can be rotated about the longitudinal axis 221 to roll the cable 224 back into the drum 212 after using the drain snake 210. The rotating handle 216 includes a gripping portion 217 and is foldable (i.e., flipped downward), making the drain snake 210 more compact for storage.

[0060] As previously mentioned, Applicant's support handle 218 is designed to be positioned above drain snake 210 during use so that drum 212 is positioned below the user's hand and / or wrist (see, e.g., Figure 6 ). The support handle 218 is rotatable to allow the user to adjust and is shaped to have an ergonomic design. Applicants believe that these aspects of the support handle design reduce the pressure on the user's hands and / or wrists and increase the comfort during use of the drain snake 210.

[0061] refer to Figure 5 , support handle 218 is coupled to neck 214, which serves as a lower support handle and is positioned between drum 212 and the end of drain snake 210. Specifically, support handle 218 includes a connecting portion 230 coupled to neck 214 by a fastener (shown as bolt 232). As will be discussed in more detail below, support handle 218 is adjustable. In another specific embodiment, support handle 218 is rotatable. Support handle 218 includes a curved shape that extends toward drum 212 and then bends toward the distal end. In a specific embodiment, support handle 218 generally faces the end of drain snake 210 and outlet opening 223 (see, e.g. Figure 7 In such an embodiment, the end surface 225 of the support handle 218 faces generally in the same direction as the distal end of the drain snake 210 (ie, away from the drum 212).

[0062] Further, the support handle 218 is located above the center of gravity of the drain snake 210 and / or slightly forward of the center of gravity of the drain snake 210. Applicants believe that the described positioning of the handle relative to the center of gravity of the tool reduces stress on the wrist of a user during use of the drain snake 210. The center of gravity of the drum 212 is behind the center of gravity of the drain snake 210, with or without the cable 224 positioned in the drum 212.

[0063] refer to Figure 8 , shows a partially exploded view of a drain snake 210 according to an exemplary embodiment, wherein a portion of the neck 214 is removed. An elongated tube 240 extends along the longitudinal axis 221 away from a lower portion 239 of the drum 212. The elongated tube 240 includes an opening 238 at an end away from the drum 212. The opening 238 of the elongated tube 240 is aligned with the outlet opening 223 of the end portion 222 (i.e., aligned along the longitudinal axis 221).

[0064] The actuator 236 includes a body 242 and a lever portion 244 extending away from the body 242. The body 242 includes a passage or through-hole 246 extending through the body 242 of the actuator 236 along a longitudinal actuator axis 254. When the cable locking assembly 220 is assembled, the longitudinal actuator axis 254 extends in the same direction as the longitudinal axis 221. Each opposite end of the body 242 includes a protrusion 250 extending away from the body 242 along the longitudinal actuator axis 254. The protrusion 250 is configured to be received and / or connected to the end portion 222 when the cable lock assembly 220 is assembled. In a specific embodiment, the protrusion 250 has a cylindrical shape. In a specific embodiment, the body 242 has a cylindrical shape. The body 242 further includes an outer surface 248.

[0065] The end portion 222 includes a recess 234 (see, e.g. Figure 6 ), the recess being sized and / or configured to receive the actuator 236 of the cable lock assembly 220. The recess 234 includes a curved surface 252 configured to engage and / or abut against the body 242, and in particular the outer surface 248 of the actuator 236. The end portion 222 further includes an actuator channel 233 extending through the end portion 222 along the longitudinal axis 221 on opposite sides of the recess 234. The actuator channel 233 receives the protrusion 250 of the actuator 236 so that the actuator 236 remains coupled to the end portion 222 during rotation of the actuator 236.

[0066] refer to Figures 9 and 10 , shows a detailed perspective view of a cable lock assembly 220 according to an exemplary embodiment. Fig. 9 The actuator 236 is shown in a first locked position, and Fig.10The actuator 236 is shown in a second unlocked position. When the actuator 236 is in the locked position, the through hole 246 is offset (i.e., misaligned) from the elongated tube 240 and / or opening 238 of the drum 212 and the actuator channel 233 of the end portion 222. This offset causes the size of the through hole 246 to decrease, which in turn presses and / or pushes the cable 224 between the wall of the actuator 236 and the wall of the elongated tube 240 (i.e., acts like an over-center locking collar), locking the cable 224 in place so that the user can manipulate the cable when the cable 224 is inserted into the drain pipe because the cable 224 is prevented from moving rotationally and / or axially. In a specific embodiment, the offset causes the diameter of the through hole 246 to decrease. Once the user of the drain snake 210 has completed manipulating the cable 224, the user can operate the lever portion 244 to move the actuator 236 in the unlocking direction shown by arrow 256. The actuator 236 rotates about the longitudinal axis 221 and the longitudinal actuator axis 254 when moving between the locked position and the unlocked position. In a particular embodiment, the actuator 236 can rotate approximately 180 degrees (ie, 180 degrees plus or minus 10 degrees).

[0067] When the actuator 236 is in the second unlocked position, the through hole 246 is aligned with the elongated tube 240 and / or the opening 238 of the drum 212 and the actuator channel 233 of the end portion 222. In this position, the cable 224 can freely rotate and / or move axially (i.e., the cable 224 can move relative to the end portion 222). When the user wants to manipulate the cable 224, the user can operate the lever portion 244 to move the actuator 236 in the locking direction indicated by the arrow 258.

[0068] refer to Figure 11 to Figure 12 , shows a cross-sectional view of a cable lock assembly 220 according to an exemplary embodiment. Fig.11 The actuator 236 is shown in a first locked position, and Fig.12 The actuator 236 is shown in a second unlocked position. Fig.11 As shown, in the locked position, the inner surface 260 of the actuator channel 233 extends further inward than the inner surface 262 of the through hole 246 of the actuator 236, thereby producing the previously described deviation. The deviation (i.e., the difference in inward extension) between the inner surface 260 of the actuator channel 233 and the inner surface 262 of the through hole 246 presses the cable 224 against the wall of the elongated tube 240. Fig.12As shown, in the unlocked position, the inner surface 262 of the through hole 246 of the actuator 236 extends around the inner surface 260 of the actuator channel 233, so that the through hole 246 is aligned with the actuator channel 233. The alignment of the through hole 246 prevents the cable 224 from being pressed against the wall of the elongated tube 240. In other words, when the actuator 236 is in the unlocked position, the actuator channel 233 and the pair of locking channels 272 are aligned with the elongated tube 240.

[0069] refer to Fig.13 , shows an exploded view of the drain snake 210 according to an exemplary embodiment. Further details of the rotating handle 216 are shown. The grip portion 217 is attached to the crank handle 213. In a specific embodiment, the grip portion 217 is coupled to the crank handle 213 by a snap fit. The grip portion 217 can rotate freely around the pillar portion of the crank handle 213. The crank handle 213 is coupled to the upper portion 219 of the drum 212 by at least one pin 264. In a specific embodiment, two pins 264 are used to attach the rotating handle 216, specifically the crank handle 213, to the upper portion 219 of the drum 212. The pins 264 are aligned with holes or holes positioned in the upper portion 219 and the crank handle 213, thereby maintaining the holes in a coaxial position. The alignment allows the crank handle 213 to rotate. In a specific embodiment, the crank handle 213 can rotate about 180 degrees (e.g., 180 degrees plus or minus 10 degrees).

[0070] refer to Figure 18 to Figure 19 , a side view of a drain snake 210 tool according to an exemplary embodiment, wherein the rotating handle 216 is in a first storage position (see e.g. Fig.18 ) and a second crank position (see e.g. Fig.19 ).exist Fig.19 In the crank position shown, the grip portion 217 of the rotating handle 216 is exposed and / or available for the user to grip. When the drum 212 rotates, the user can grip the grip portion 217 of the rotating handle 216. Once the user has finished using the drain snake 210, the rotating handle 216 can be rotated 180 degrees so that the grip portion 217 is not exposed and / or available for the user to grip (see, e.g. Fig.18 In other words, the rotating handle 216 includes a gripping portion 217 and is movable between a crank position, in which the gripping portion 217 extends away from the drum 212 for gripping by a user, and a storage position, in which the gripping portion 217 extends toward the drum 212 such that the rotating handle 216 forms a flat and / or planar surface.

[0071] like Fig.18As shown, in the storage position, the crank handle 213, specifically the outer surface 215 of the crank handle 213, forms a support (e.g., a flat or planar surface), thereby allowing the drain snake 210 to be stored upright (e.g., a vertical position or the tool is in a longitudinal orientation) with the rotating handle outer surface 215 located on a support surface (the ground, a table, etc.). Applicants believe that the rotatable rotating handle 216 and upright storage not only make it easier to store the drain snake 210 (i.e., taking up less space), but also that the storage position allows any excess moisture and / or liquid to drain from the drum 212, keeping the drain snake 210 in working condition and increasing the life of the tool.

[0072] refer to Fig.13 , further details of the drum 212 and the elongated tube 240 are shown. The cable 224 is schematically shown as a loop positioned between the upper portion 219 and the lower portion 239 of the drum 212. As previously discussed, the opening 238 is positioned at the end of the elongated tube 240 away from the drum 212. The transverse hole 266 is also positioned at the distal end of the elongated tube 240. The transverse hole 266 is positioned in an orientation that is generally perpendicular to the opening 238 (i.e., 90 degrees plus or minus 10 degrees). The transverse hole 266 allows the elongated tube 240 to be coupled and / or attached to the end portion 222, specifically to the alignment lug 268 of the end portion 222.

[0073] refer to Figure 14 to Figure 15 , shows a detailed view of the end portion 222 according to an exemplary embodiment. When the drain snake 210 is assembled, the proximal channel 270 of the end portion 222 is aligned with the opening 238. The end portion 222 further includes a distal channel 270 aligned with the opening 238. When the alignment lugs 268 positioned within the proximal channel 270 and / or the distal channel 270 engage the transverse hole 266, rotation and / or axial movement of the end portion 222 is prevented.

[0074] In a particular embodiment, the end portion 222 includes two components. Applicants have designed each component and / or half of the end portion 222 to be used twice in the drain snake 210 to reduce cost (i.e., limit tooling) and increase ease of assembly. Accordingly, features on each component are present on both the left and right sides of the component, so each feature will be discussed once. The end portion 222 includes locking channels 272 that are part of the cable locking assembly 220 and are offset from the longitudinal axis 221. The locking channels 272 are positioned between each actuator channel 233 and the proximal or distal channel 270.

[0075] The longitudinal axis, shown as the central axis 274 of the end portion 222, extends between the outlet opening 223 and an opposing opening 273 positioned adjacent and / or proximal to the proximal channel 270. The locking channel 272 extends along the central axis 274 of the end portion 222 and is positioned on opposite sides of the actuator 236. The locking channel 272 is offset below the central axis 274 (i.e., not centered on the central axis 274). Instead, the locking channel 272 is centered around the locking axis 276. In other words, the locking channel 272 is centered around the locking axis 276, which extends in a parallel orientation and is offset from the central axis 274 of the end portion 222 by a distance, and this offset to the locking channel 272 creates an interference point so that the cable 224 is pressed against the inner surface of the elongated tube 240 to lock the cable 224 in place (i.e., preventing rotation and axial movement of the cable 224). The locking axis 276 extends between the outlet opening 223 and the opposite opening 273 and is parallel to the central axis 274 of the end portion 222. In other words, when the locking channel 272 deviates from the central axis 274, the locking axis 276 is parallel to the central axis 274 and not colinear. The deviation of the locking channel 272 creates an interference point or pinch point that presses the cable 224 against the wall of the elongated tube 240, thereby retaining and / or locking the cable 224 in place. In a specific embodiment, the deviation or difference between the central axis 274 and the locking axis 276 is between 0.65 mm and 1.05 mm, specifically between 0.75 mm and 0.95 mm, more specifically between 0.80 mm and 0.90 mm. In such an embodiment, the deviation of the locking channel 272 is about 0.85 mm (e.g., 0.85 mm plus or minus 0.02 mm).

[0076] As previously discussed, the actuator 236 also has an offset. The through hole 246 and the longitudinal actuator axis 254 are offset below the central axis 274, and the longitudinal actuator axis 254 is parallel to the central axis 274. In other words, when the actuator 236 is in the unlocked position, the actuator longitudinal axis 254 (shown as the central axis) and the longitudinal axis 221 of the drain snake 210 and / or the central axis 274 of the end portion 222 are collinear. When the actuator 236 is rotated to the locked position, the position of the actuator 236 moves so that the actuator axis 254 is parallel to the longitudinal axis 221 of the drain snake 210 and / or the central axis 274 of the end portion 222, but not collinear.

[0077] In a specific embodiment, the deviation or difference between the central axis 274 and the actuator longitudinal axis 254 is between 0.65 mm and 1.05 mm, specifically between 0.75 mm and 0.95 mm, more specifically between 0.80 mm and 0.90 mm. In such an embodiment, the deviation of the hole 246 of the actuator 236 is about 0.85 mm (e.g., 0.85 mm plus or minus 0.02 mm).

[0078] In a particular embodiment, the through hole 246 of the actuator 236 and the locking channel 272 are offset in the same direction (i.e., below the central axis) by the same amount. In other words, in such an embodiment, the actuator channel 233 is offset from the longitudinal axis 221 of the drain snake 210 by the same distance as the locking channel 272, and the offset of the actuator channel 233 is in a first direction relative to the central axis 274 (i.e., the longitudinal axis of the end portion 222), and the offset of the locking channel 272 is in a first direction relative to the central axis 274.

[0079] When the actuator 236 and the locking channel 272 deviate by the same amount in the same direction, the actuator and the locking channel will be perfectly aligned in one orientation, which is the unlocked position. When the actuator 236 rotates 180 degrees, the deviation will rotate 180 degrees, so that the through hole 246 and the locking channel 272 will deviate by twice the distance from the central axis 274. In other words, the total deviation distance is equal to the distance that the actuator channel 233 deviates plus the distance that the pair of locking channels 272 deviate. In a specific embodiment, the deviation amount of the locked position is between 1.3 mm and 2.1 mm, specifically between 1.5 mm and 1.9 mm, and more specifically between 1.6 mm and 1.8 mm. In such an embodiment, the deviation amount of the cable lock assembly 220 is about 1.7 mm (e.g., 1.7 mm plus or minus 0.1 mm).

[0080] Applicants have found that when the diameter of the cable 224 is 6.35 mm (1 / 4 inch), the total deflection or interference of the cable locking assembly 220 should be about 1.7 mm (e.g., 1.7 mm plus or minus 0.1 mm). If the deflection is much smaller, the cable 224 has sufficient flexibility to be pulled through the deflection. If the deflection is much larger, the cable 224 will be too stiff to deform and will break off the end portion 222 and / or the actuator 236, or it will be too difficult (i.e., too much resistance) to rotate the actuator 236 180 degrees. Similar deflection combinations can be used for cables with diameters other than 6.35 mm.

[0081] refer to Fig.16, shows an exploded side view of a support handle 218 of a drain snake 210 according to an exemplary embodiment. The support handle 218 includes a connection portion 230 including a counterbore configured to receive a fastener (shown as a bolt 232) and a countersunk bore of a spring (shown as a wave spring 278). The neck 214 includes a connection portion 282 configured to engage the connection portion 230. The connection portion 230 of the support handle 218 further includes a mating tooth 280, and the connection portion 282 of the neck 214 includes a mating tooth 284 configured to engage with the mating tooth 280. The mating teeth 280, 284 allow the support handle 218 to rotate 360 ​​degrees about a bolt axis 285 extending along the longitudinal axis of the bolt 232. In a particular embodiment, the support handle 218 can rotate in increments of 30 degrees so that a user can position and / or move the support handle 218 to a position suitable for use with the drain snake 210. In other words, the adjustable support handle 218 is positioned between the drum 212 and the end portion 222, and the support handle 218 is configured to allow 360 degree rotation about a rotation axis (ie, the bolt axis 285) extending in a direction substantially perpendicular to the longitudinal axis 221 of the drain snake 210.

[0082] When the user wants to adjust the support handle 218, the support handle is pulled in an upward direction (i.e., vertical or longitudinal direction of the bolt 232) or in a direction transverse and / or substantially perpendicular (e.g., 90 degrees plus or minus 10 degrees) to the longitudinal axis 221 of the drain snake 210, thereby compressing the wave spring 278 and creating a space and / or gap between the mating teeth 280, 284. Once the support handle 218 is raised, the user can rotate the support handle 218 to the desired position and then release or lower the support handle 218. When the support handle 218 is released, the wave spring 278 is no longer compressed, but locks and / or holds the support handle 218 in the new position.

[0083] refer to Fig.17 , shows a cross-sectional view of a drain snake 210 according to an exemplary embodiment. The support handle 218 is located above and / or slightly forward of the center of gravity 286 of the drain snake 210. In a particular embodiment, the center of gravity 286 is located within the lower portion 239 of the drum 212 or between the upper portion 219 and the neck 214. The center of gravity 286 is specifically located within the proximal end of the elongated tube 240 that extends into the lower portion 239 of the drum 212.

[0084] Compared with various drain augers discussed herein, many augers have extended bodies or rigid portions, which may make it difficult to manipulate or carry the drain augers without causing damage (e.g., scraping against walls, colliding with objects, etc.). Applicants believe that drain augers comprising multiple tubes connected by a folding mechanism with flexible or foldable portions allow for easier transportation and storage. For example, an augers with the folding mechanism discussed can allow a functionally 6-foot augers to be folded and transported and / or stored with a length less than 6 feet. In addition, when in the folded position, the open end containing the handle and the relative open end with the sheath are all oriented so that these open ends face upward (i.e., along the longitudinal axis of the auger and / or angled so that the foldable portion is closer to the ground). The folding orientation described herein allows the auger to maintain and / or retain any liquid or debris in the middle portion, such as the tube, during transportation (i.e., outdoors) before flushing (i.e., flushing with a garden hose, etc.).

[0085] refer to Figure 20 to Figure 21 , showing various aspects of a drain cleaning tool shown as a drain auger 310. The drain auger 310 includes a head portion 312, a body 314, Fig. 20 Schematically shown is a cable or coil 315 and a handle 324. The cable 315 extends from the handle 324 through the body 314 and the tip portion 312 of the drain auger 310. The tip portion 312 is coupled to the body 314 at the bottom or lower end. The tip portion 312 is formed of a flexible material (e.g., rubber, silicone, etc.). The flexible tip portion 312 allows for easier insertion into an appliance such as a toilet bowl while also preventing accidental damage (e.g., chipping, scratching, etc.).

[0086] The end portion 312 includes a sheath opening 325. In certain embodiments, the body 314 and / or the sheath opening 325 are sized to fully receive the cable 315, which further helps prevent scratching of the toilet bowl. In certain embodiments, the cable 315 includes an end or bulb portion 344 (see, e.g., Fig.25 ), the end or ball portion can be used to break or retrieve objects or debris (e.g., hair) that cause obstructions in drains or pipes. In other embodiments, the cable 315 may not include a ball portion or may include another attachment tool at the distal end.

[0087] The cable 315 includes a flexible portion 316, a rigid portion 318 (see, e.g. Fig.25) and an angled portion 322. The end of the cable 315 including the angled portion 322 is coupled to a handle 324. The opposite end of the cable 315 extends through an elongated tube or passageway within the body 314 and the tip portion 312 of the drain auger 310. The combination of the flexible portion 316 and the rigid portion 318 allows a user to fold the drain auger 110 so that the drain auger has a reduced length for storage and / or transportation of the tool. While the flexible portion 316 facilitates the folding of the cable 315, the rigid portion 318 ensures that the user is able to generate sufficient force to break through a drain obstruction.

[0088] To use the drain auger 310, the user inserts the head portion 312 into a sanitary fixture such as a toilet. The user can then rotate the handle 324 in a first direction while pushing downward (e.g., toward the toilet) to move the cable 315 into the body 314 and out of the head portion 312 through the sheath opening 325, so that the cable 315 extends into the toilet and the connected plumbing system where an obstruction may exist. If necessary, the handle 324 can be used to pull back and re-extend the cable 315 until the obstruction is cleared or removed.

[0089] refer to Fig. 22 , a stereoscopic view of the top portion of a drain auger 310 according to an exemplary embodiment is shown. Once the obstruction is removed, the cable 315 can be retracted from the plumbing system by rotating and / or pulling the handle 324 upward (e.g., away from the toilet). After use, the drain auger 310 can be easily cleaned. The upper end of the body 314 of the drain auger 310 is connected to the top portion 320 that acts as a funnel. The top portion 320 includes an inclined portion or an angled portion 336. The angled portion 336 is configured to receive at least a portion of a hose or pipe. The hose can be placed in the angled portion 336 of the top portion 320 so that when the water is drained, the hose is introduced into the body 314, thereby removing any debris (e.g., drain obstruction) or liquid remaining in the drain cleaning process from the drain auger 310. The top portion 320 further includes an opening 334 connected to an elongated tube or passage in the body 314. The size of the top portion 320 and the opening 334 is determined to allow water to flow through the body 314 and the tip portion 312 and / or be sprayed through the body and the tip portion during the cleaning process. Specifically, the opening 334 is configured to allow water to be sprayed through the body 314 so that debris and / or liquid remaining in the passage is removed (i.e., the passage is flushable).

[0090] refer to Figure 23 to Figure 25, a folding mechanism that allows the drain auger 310 to fold is shown according to an exemplary embodiment. The body 314 of the drain auger 310 includes an upper portion 326 and a lower portion 328. The folding mechanism includes a connector or coupler 330. The coupler 330 is positioned between the upper portion 326 and the lower portion 328 of the body 314 and is coupled to the upper portion and the lower portion. A tube 338 is at least partially positioned within the coupler 330. The tube 338 is positioned between the upper portion 326 and the lower portion 328 of the body 314 and is connected to the upper portion and the lower portion. The connection between the tube 338 and the upper portion 326 and the lower portion 328 of the body 314 maintains the elongated tube or passageway within the drain auger 310 so that the passageway is continuous between the upper portion 326 and the lower portion 328. In a specific embodiment, the tube 338 is formed of a flexible material (e.g., rubber, silicone, etc.). In a particular embodiment, tube 338 is formed from rubber.

[0091] The coupling 330 locks together the upper portion 326 and the lower portion 328 of the body 314. Specifically, the coupling rotates to lock the upper portion 326 and the lower portion 328 together through a rotational interlock. The pin 340 holds the coupling 330 in place so that the coupling does not rotate and / or unlock. Fig.23 The pin 340 is shown in a locked position preventing the coupling 330 from rotating (i.e., fully engaged with the coupling 330). Fig.24 326, the pin 340 is in an unlocked position that allows the coupler 330 to rotate (i.e., not fully engaged with the coupler 330). Specifically, a bottom portion 342 of the coupler 330 connected to the distal end of the tube 338 (i.e., the end near and / or adjacent to the lower portion 328) is locked and / or retained to the upper portion of the coupler 330 by the pin 340. The proximal end of the tube 338 (i.e., near and / or adjacent to the upper portion 326) is coupled to the upper portion 326 and / or the upper section or body of the coupler 330.

[0092] like Figure 23 to Figure 24 As shown, the tube 338 is in a compressed position within the coupler 330 (when the drain auger 310 is in the extended position). Fig.25In the embodiment of the present invention, the tube 338 is in an extended position to facilitate transportation and / or storage of the drain auger 310. As discussed, when the tube 338 of the drain auger 310 is in the extended position, any liquid and / or debris is retained and / or trapped within the tube 338 of the drain auger 310 during transportation (i.e., outdoors). In the extended position, the tube 338 expands, and the length between the upper portion 326 of the body 314 and the lower portion 328 of the body 314 increases. Specifically, the distance and / or length defined between the lowermost portion of the upper portion 326 and the uppermost portion of the lower portion 328 in the extended position is greater than the length and / or distance defined between the lowermost portion of the upper portion 326 and the uppermost portion of the lower portion 328 in the compressed position.

[0093] In the collapsed position, the drain auger 310 has two open ends, both of which include a top portion 320 and a tip portion 312 that point in a similar or same direction (e.g., upward) for transportation. Because the opening 334 in the top portion 320 and the jacket opening 325 face and / or point upward, any debris or liquid remaining after using the drain auger 310 will be located in the tube 338, which is in a relatively low position. The opening 334 and the jacket opening 325 are positioned above the tube 338 and / or at a relatively high position relative to the tube, so that gravity will keep any liquid and / or debris within the drain auger 310 during transportation. In other words, when the drain auger 310 is in the collapsed position, the opening 334 is positioned above the tube 338, and the lower portion 328 of the body 314 is positioned so that the outlet or jacket opening 325 is located above the tube 338, so that debris or liquid located within the body 314 will move into the tube 338.

[0094] In other words, when the drain auger 310 is in the extended position, the distance between the first end of the tube 338 and the second end of the tube 338 defines a first length, and when the drain auger 310 is in the collapsed position, the distance between the first end of the tube 338 and the second end of the tube 338 defines a second length. In a particular embodiment, the second length is greater than the first length.

[0095] The drain auger 310 further includes one or more retaining components, shown as clamps 332. The clamp 322 is coupled to the upper portion 326 of the body 314. The clamp 332 includes a retaining arm extending outwardly. The arm extends at least partially around the body 314, specifically around the lower portion 328. In a specific embodiment, the clamp 332 is positioned at an angle relative to the longitudinal axis of the drain auger 310 and / or the upper portion 326. When the drain auger 310 is folded, the end portion 312 is positioned above the clamp 332. When the clamp 332 is coupled to the lower portion 328 of the body 314, the lower portion 328 is positioned at an angle relative to the longitudinal axis of the drain auger 310. When the drain auger 310 is in the collapsed position, the tube 338 extends and / or bends such that the lower portion 328 is positioned to extend the upper portion 326 and / or top portion 320 and the retaining arms of the clamp 322 engage the outer sidewall of the lower portion 328 of the body 314 .

[0096] In other words, when the folding mechanism is in the extended position, the upper portion 326 of the body 314 and the lower portion 328 of the body 314 are aligned along the longitudinal axis of the drain auger 310 (i.e., the longitudinal axes of the upper portion 326 and the lower portion 328 are co-linear). When the folding mechanism is in the folded position, the lower portion 328 is rotated to a position where the upper portion 326 of the body 314 and the lower portion 328 of the body 314 are not aligned along the longitudinal axis of the drain auger 310 (i.e., the longitudinal axes of the upper portion 326 and the lower portion 328 are not co-linear).

[0097] In a specific embodiment, the total length or extended length of the drain auger is about 6 feet (e.g., 6 feet plus or minus 6 inches). In such an embodiment, the collapsed length of the drain auger 310 is less than 6 feet.
