[0003] The present subject matter relates to drain cleaning devices, and in particular to drain cleaning devices using a sheathed flexible shaft drain cleaning cable. Background Art

[0004] A large number of drain cleaning devices are known. Flexible shaft type drain cleaners use a rotatable flexible cable member surrounded by a non-rotating sheath. The cable member and sheath are typically located within a circular channel of a barrel or other housing component of the drain cleaner.

[0005] Flexible shaft type drain cleaners typically enable an operator to extend or retract a flexible cable from the drain cleaner, such as in applications where the distal end of the cable is inserted into a clogged or obstructed pipe or other member. A source of rotational power is engaged or otherwise applied to the proximal end of the flexible cable (e.g., at the drain cleaner) such that the cable member rotates under power within the sheath. Various tools (e.g., a rotary cutting head) can be attached at the distal end of the cable for clearing clogs within pipes or other operations.

[0006] Some flexible shaft type drain cleaners are typically operated in a horizontal orientation, wherein the cable guide rotates about a vertically oriented axis when the flexible cable is extended or retracted relative to the drain cleaner. This helps the cable wrap around the internal barrel channel when the cable is retracted into the drain cleaner.

[0007] While satisfactory in many respects, there remains a need for improved drain cleaning devices, particularly such devices utilizing a sheathed flexible shaft drain cleaning cable. Summary of the invention

[0008] The difficulties and drawbacks associated with previous approaches are addressed in the present subject matter as follows:

The drain cleaner also includes a cable clamp mounting assembly disposed within the internal area. The cable clamp mounting assembly defines an axle receiving area. The drain cleaner also includes a rotary power shaft assembly for receiving rotary power. The rotary power shaft assembly is disposed in the axle receiving area and is at least partially supported by the cable clamp mounting assembly. The axle receiving area defines an inclination angle in the range of 10° to 80°.

[0043] The present subject provides a kind of drain cleaner that is suitable for use with the flexible drain cleaning cable of sheath.The cable or multi-section cable that is joined together can be conveniently and neatly coiled in the inner area of ​​drain cleaner.The proximal end of the drain cleaning cable fixed in the drain cleaner is joined to the drive shaft assembly.The rotary power source can be joined to the drive shaft assembly beside the outside of the drain cleaner.The rotary power applied to the drive shaft causes the flexible cable member enclosed in the non-rotating sheath of the drain cleaning cable to rotate.The far end of the drain cleaning cable extends from the housing cover opening, the cable port opening, or the cable outlet in the drain cleaner housing.The operator can easily make the drain cleaning cable from the drain cleaner and remove the pipeline obstruction by the far end of the cable.The unique structure inside the drain cleaner enables the operator to easily collect the extended cable back to the inner area of ​​the drain cleaner in the stacking coil.It will be appreciated that the present subject includes a structure in which the cable is not collected in the stacking coil.For example, the cable can be collected in the coil, and the cable is not necessary to be stacked.In addition, the present subject includes a structure in which the cable is collected in the inner area of ​​the housing in a random manner. Additional features are described that enable convenient fastening of the drain cleaning cable to the housing of the drain cleaner.

[0044] Figure 1 and Figure 2 An embodiment of a drain cleaner 10 according to the present subject is shown. The drain cleaner 10 includes a first housing part or top housing part 20, and a second housing part or bottom housing part 30. The size and shape of the top housing part 20 and the bottom housing part 30 are designed to engage with each other in a cooperative manner to define a substantially closed hollow internal area 34. The present subject includes embodiments utilizing a single or integral housing (i.e., without multiple housing parts). The resulting housing is generally annular in shape. One or more portions of a flexible shaft drain cleaning cable 40 are at least partially disposed within the internal area 34. The flexible cable 40 defines a proximal end 42 and an opposite distal end 44. The drain cleaner 10 also includes a rotating power shaft assembly 50, which is generally supported by one or both of the top housing part 20 and the bottom housing part 30. The drain cleaner 10 may also include one or more handles and / or gripping members for ease of handling and / or use by an operator. In an illustrative embodiment, the drain cleaner 10 includes a handle 60. As described in more detail herein, the drain cleaner 10 also includes an inner cone support member 70 that facilitates management of the flexible cable 40 within the interior region 34 of the drain cleaner 10. The drain cleaner 10 also includes a cable clamp mounting assembly 90 disposed within the interior region 34 of the drain cleaner 10. As described in more detail herein, the cable clamp mounting assembly 90 supports the rotary power shaft assembly 50 and orients the proximal end 42 of the flexible cable 40 for improved engagement of the rotary power shaft assembly 50.

[0045] Further references Figure 1 and Figure 2 , the first housing member 20 and the second housing member 30 are fixed to each other or otherwise fastened to each other. In the drain cleaner 10 shown, a plurality of fasteners 36 are used to releasably engage the first housing member 20 and the second housing member 30 together. As will be appreciated, the hole 22 can be defined in the first housing member 20 and a corresponding receiving member 32 disposed in the second housing member 30. The hole 22 and the receiving member 32 are aligned and adapted to receive the fastener 36 in engagement. As will be appreciated, other configurations and / or components can be used to fasten the first housing member 20 and the second housing member 30 together. In addition, as previously described, the present subject matter includes the use of a single housing, rather than a plurality of housing members fixed or engaged together. The present subject matter also includes housing members attached by releasable fasteners (e.g., latches) and / or without the use of a housing cover.

[0046] The first housing component 20 defines a centrally located cable port 26 that provides access to an interior region 34 defined by the housing components 20, 30. In certain versions, the first housing component 20 further defines a conical tapered edge 24 that extends around the cable port 26. The conical tapered edge 24 can be in the form of a funnel or depression along the exterior or first face 21 of the first housing 20 that extends around the perimeter of the cable port 26. As described in greater detail herein, when the flexible cable 40 is placed within the interior region 34, the distal end 44 of the cable 40 and portions of the cable 40 can extend through the cable exit or cable port 26. In versions of the first housing component 20 that define the conical edge 24, the edge 24 extends symmetrically around the cable port 26. The conical edge 24 facilitates and / or facilitates cable feeding, cable retrieval, or one or more other cable management operations.

[0047] The drain cleaner 10 also defines a channel 28 in one or both of the first housing member 20 and the second housing member 30, through which the rotary power shaft assembly 50 can be accessed. In the depicted embodiment, in the drain cleaner 10, the channel 28 is in the form of an opening in the first housing member 20, and the size and shape of the first housing member 20 are designed to be able to engage the rotary power shaft assembly 50. As described in more detail herein, the channel 28 is configured to allow convenient access to the outwardly extending drive shaft 52 of the rotary power shaft assembly 50. In some versions, the channel 28 is configured to also allow for ready engagement of the drive shaft 52, which extends outward at an acute angle or 0 to 90 degrees and including 0 and 90 degrees relative to a plane that generally bisects the housing members 20, 30, and is generally parallel to the interface of the housing members 20, 30. It is understood that the present subject matter includes various arrangements and orientations of the channel 28 and the drive shaft 52. For example, in some versions, the drive shaft 52 can extend outward in a direction parallel to the plane. In such a configuration, the angle is 0 degrees. Certain angular orientations of drive shaft 52 in certain versions are described in greater detail herein.

[0048] Figures 3 to 5 The drain cleaner 10 and various features are shown in greater detail. Specifically, Figure 4 is along Figure 3 The cross section is taken along the section line shown, and the inner cone support member 70 is shown. The inner cone support member 70 extends into the interior area 34 of the drain cleaner 10. The configuration of the inner cone support member 70 provides an outer recessed area 72 along the outer face 31 as viewed from the exterior or second face 31 of the second housing component 30. However, it will be appreciated that the second housing component 30 can include structure or members to avoid the recessed area 72, such as a flat planar member (not shown). The inner cone support member 70 is generally aligned with the cable port 26 and is centrally located relative to the cable port 26. Reference Figure 4 Preferably, the inner cone support member 70 and the cable port 26 share a common central axis shown as axis X.

[0049] In a particular version, the inner cone support member 70 has a bi-conical configuration as follows. The support member 70 includes a first tapered region 74 extending between a planar wall 76 of the second housing component 30 and a circular stripline 78 defined around the perimeter of the support member 70. The support member 70 includes a second tapered region 80 extending between the stripline 78 and an apex 82 of the support member 70. In this version, the configuration of the first tapered region 74 is different from the configuration of the second tapered region 80. More specifically, when viewed from the perspective of FIG. Figure 4When viewed in cross section as shown, the angle at which the walls of the first tapered region 74 are oriented is different from the angle at which the walls of the second tapered region 80 are oriented. For example, typically the angle at which the walls of the first tapered region 74 are oriented relative to plane Y of the planar wall 76 is in the range of 45° to 80°, and preferably about 55°. Typically, the angle at which the walls of the second tapered region 80 are oriented relative to plane Y is in the range of 10° to 45°, and preferably about 35°. The relatively large angle of the first tapered region 74 improves retention of the cable within the interior region 34 of the drain cleaner 10. The relatively small angle of the second tapered region 80 facilitates and guides the coiled arrangement of the cable within the interior region 34 of the drain cleaner 10.

[0050] Figure 6 The rotary power shaft assembly 50 and the cable clamp mounting assembly 90 are shown in greater detail. Figure 6 Also shown is the proximal end 42 of the flexible drain cleaning cable 40. The rotary power shaft assembly 50 includes a drive shaft 52. The drive shaft 52 defines a proximal end 54 and an opposite distal end 56. The proximal end 54 is suitable for coupling or otherwise fixing to the proximal end 42 of the flexible cable 40. Typically, the proximal end 54 of the drive shaft 52 is engaged to the proximal end 42 of the flexible cable 40 at a position within the internal area 34 of the drain cleaner 10. A fixing pin 59 can be used to fix the proximal end 42 of the flexible cable 40 to the proximal end 54 of the drive shaft 52. The distal end 56 of the drive shaft 52 is suitable for engaging to a rotary power source (not shown). Examples of rotary power sources can include handheld electric drills. Preferably, the handheld electric drill is a battery-powered drill. It is understood that the distal end 56 of the drive shaft 52 can be accessed through the channel 28 defined in the housing of the drain cleaner described previously. The distal end 56 of the drive shaft 52 can include various cross-sectional shapes, such as square or hexagonal, to facilitate engagement with a rotary power source. The rotary power shaft assembly 50 may also include one or more bearings 58 to facilitate rotation of the shaft 52 and / or rotationally support the shaft 52. Typically, engagement between the rotary power source and the distal end 56 of the drive shaft 52 occurs at a location along the exterior of the drain cleaner 10. In certain applications, particularly if the rotary power source is a handheld electric drill (e.g., a battery-powered drill), the drill can be positioned to contact one or both of the first housing member 20 and the second housing member 30. The exterior profile of the drain cleaner 10 can be configured to contact and receive a typical handheld drill placed in or on the housing so that the housing counteracts the torque generated by the operation of the drill. It will be appreciated that the subject matter includes a large number of placement and / or positioning arrangements of the rotary power source relative to the drain cleaner 10.

[0051] The cable clamp mounting assembly 90 generally includes a first member or top member 92 and a second member or bottom member 94. One or both of the first member 92 and the second member 94 define a shaft receiving area 96 at one end 97 and a cable receiving area 98 at the other end 99. When the first member 92 and the second member 94 are placed and engaged with each other, the shaft receiving area 96 is sized and shaped to receive at least a portion of the drive shaft 52, and the cable receiving area 98 is sized and shaped to receive the proximal end 42 of the flexible cable 40 and at least a portion of the flexible cable 40. Specifically, when the first member 92 is engaged with the second member 94, the resulting engagement defines the shaft receiving area 96 at one end 97 and the cable receiving area 98 at the other end 99. A plurality of fasteners 100 can be used to releasably engage the first member 92 and the second member 94 together. As will be appreciated, holes 102 can be defined in the first member 92 and corresponding receiving areas 104 disposed in the second member 94. One or more bearing support areas 106 can be provided in one or both of the first member 92 and / or the second member 94. As will be appreciated, the bearing support areas 106 are sized and shaped to receive, secure, and support the bearings 58. In some versions, the first member 92 and / or the second member 94 are used to clamp and secure the distal end 42 of the drain cleaning cable 40, and also to clamp and secure one or more bearings 58.

[0052] In certain versions of the cable clamp mounting assembly 90, the cable receiving area 98 defined by the first member and / or the second member 94 extends along a curved or arcuate axis, and in certain versions along a helical axis. Figures 19 to 21 , showing a second member 94A, which presents a spiral cable receiving area 98A. It is understood that the second member 94A can be used similar to Figure 6 In the cable clamp mounting assembly of the previously described assembly 90 shown in FIG. Figures 19 to 21 , the second member 94A defines a spiral cable receiving area 98A. The spiral configuration of the cable receiving area 98A is in a first plane (e.g., Fig. 20 When viewing member 94A from the top of member 94A) and a second plane perpendicular to the first plane (e.g., as shown in FIG. Fig.21 The cable receiving area 98A is provided with an arcuate or curved path (as shown when viewing the member 94A from the end of the member 94A). This particular configuration of the cable receiving area 98A and / or the member 94A results in improved operating efficiency and reduces the likelihood of binding or abrasion of the drain cleaning cable located within the cable receiving area 98A. It is understood that the subject matter includes variant configurations, such as non-spiral paths for the cable receiving area 98, such as configurations in which the area 98 extends in an arcuate manner in only one of the planes.

[0053] Figures 7 to 9 An optional wear-resistant insert 110 for use in an embodiment of the drain cleaner 10 is shown. As previously described, the first housing member 20 defines a cable outlet or cable port 26 that provides access (i.e., entry and / or exit) to an interior area 34 defined by the joined first housing member 20 and second housing member 30. The size and shape of the wear-resistant insert 110 are designed to appropriately engage with the portion of the housing member 20 that defines the cable port 26. Typically, the cable port 26 is in the shape of a circular opening, and thus the shape of the wear-resistant insert 110 is also circular. However, it will be appreciated that the subject matter includes other shapes and configurations. Additionally, in some versions, the wear-resistant insert 110 is rotatably engaged with the first housing member 20, so that the member 110 is able to rotate in the cable port 26 in which it is engaged and fixed. Likewise, it will be appreciated that the subject matter includes a large number of other configurations and versions of wear parts, such as non-rotatable engagements and non-circular shapes.

[0054] The wear insert 110 is used to provide a low friction contact point for the flexible drain cleaning cable 40 entering or exiting the interior area 34 of the drain cleaner 10. Thus, in many versions, the wear insert 110 is formed from or includes an outer coating of a low friction material, such as, but not limited to, polytetrafluoroethylene (PTFE), nylon-based materials, and / or acetal-based materials as are known in the art. The present subject matter encompasses the use of other low friction materials. It is contemplated that the wear insert 110 can be easily replaced if excessive wear occurs.

[0055] Figure 7 Another aspect of certain versions of drain cleaners is also shown, such as the illustrated embodiment of drain cleaner 10. In this aspect, the outwardly extending distal end 56 of the drive shaft 52 is oriented within an angle range of about 10° to about 80°, and in certain versions about 30°. These illustrated angles are Figure 7, and is obtained for the aforementioned planar wall 76 of the second housing component 30. The angular orientation of the drive shaft 52 can be achieved by the configuration of the cable clamp mounting assembly 90. In many embodiments, the angular orientation of the drive shaft 52 is determined by the tilt angle defined by the shaft receiving area 96 of the cable clamp mounting assembly 90. The tilt angle is represented as the angle Z described previously. Therefore, typically, the tilt angle of the shaft receiving area is in the range of about 10° to about 80°, and in some versions is about 30°. The angular orientation of the drive shaft 52 can facilitate ergonomic placement and positioning of the handheld drill next to the drain cleaner. However, it is understood that the present subject matter includes other configurations and drive shaft orientations. For example, the present subject matter includes a drain cleaner with a drive shaft that is oriented to extend at an angle perpendicular to or substantially perpendicular to a plane that bisects the housing components 20, 30 and is parallel to the interface of the housing components 20, 30. The present subject matter also includes a drain cleaner with a drive shaft oriented to extend at an angle parallel or substantially parallel to a plane bisecting the housing components 20, 30 and parallel to the interface of the housing components 20, 30. The drive shaft 52 is located on a side of the housing spaced from the center of the housing. The location of the drive shaft 52 and the cable clamp mounting assembly 90 is such that power is transmitted substantially tangentially to the coiled portion of the flexible cable 40 within the inner cavity 34 of the drain cleaner 10.

[0056] Figures 10 to 13 A cable guide assembly 120 for use in an embodiment of the drain cleaner 10 is shown. Fig.10 The second housing component 30 and the duct component 120 rotatably fastened to the second housing component 30 are shown. In the described embodiment, the duct component 120 is rotatably fastened to the inner cone support member 70, and the duct component 120 surrounds the combined Figure 4The conduit 120 promotes and / or assists in guiding a flexible drain cleaning cable (not shown) into or out of the interior area 34 of the drain cleaner 10. The conduit 120 includes a cylindrical trunk 122 and an arm 124 extending outwardly from the trunk to the arm distal end 126. The conduit 120 defines a channel 128 extending between an end 121 of the trunk adjacent to the cable port 26 defined in the first housing portion 20 and the arm distal end 126. The size and shape of the channel 128 are designed to accommodate a flexible drain cleaning cable axially displaced therethrough. As will be understood, when the flexible cable extends or retracts from the interior area 34 of the drain cleaner 10, the conduit 120 rotates about the axis X. Therefore, the rotation of the conduit 120 occurs when the flexible cable passes through (i.e., axially displaces through) the channel 128 extending between the ends 121 and 126 of the conduit 120, and is wound into a coil in the interior area 34. The direction of rotation of the conduit 120 depends on whether the drain cleaning cable is extended from the drain cleaner 10 or guided into the drain cleaner 10. When the cable is extended from the drain cleaner 10, the conduit 120 rotates in a first rotation direction, i.e., clockwise or counterclockwise. When the cable is retracted, the conduit 120 rotates in a second rotation direction opposite to the first rotation direction.

[0057] Fig.14 Shown before the combination Figure 6 A cable clamp mounting assembly 90 is described. Fig.14 An optional use of a clutch assembly 140 is depicted. The clutch assembly 140 provides a rotatably engageable and / or disengageable connection between the proximal end 54 of the first drive shaft portion 52A and the distal end 56 of the second drive shaft portion 52B. As will be appreciated, the clutch assembly 140 can be used to selectively disengage the rotation of a rotary power source (not shown) (e.g., disengage the rotation of the rotary power source applied to the distal end 56 of the drive shaft portion 52B), and can be used to selectively disengage the rotation of the flexible cable 40 engaged with the proximal end 54 of the drive shaft portion 52A. In certain applications, the application of high levels of torque to the rotary power shaft assembly 50 may damage the flexible drain cleaning cable engaged therewith. The incorporation of the clutch assembly 140 can be used to prevent excessive levels of torque from being transmitted from the rotary power source to the drain cleaning cable, and thereby prevent such damage. As previously described in conjunction with Figure 6As described, the various components can be supported using one or more bearings 58 and secured to the first member 92 and the second member 94. In a particular version, the clutch assembly 140 can be in the form of a clutch with an internal spring biasing mechanism (and in particular a spring biased pawl mechanism). However, a wide variety of clutch mechanisms can be used, such as a drill clutch using a series of balls or sliders and a spring plate with a means to enable the plates to be axially separated and temporarily disengaged from another plate in mechanical communication with the drain cleaning cable.

[0058] Figures 15 to 18 An optional locking clip assembly 130 is shown for use in an embodiment of the drain cleaner 10. The locking clip assembly 130 includes a pivotable member 132 that is movably secured at a base 134 adjacent to the cable port 26 defined in the first housing component 20. In this version, the housing component 20 also defines a cable port 136 that communicates with the cable port 26. The cable port 136 is sized and shaped to receive the flexible cable 40. The member 132 is positionable and pivotally secured at the base 134 to control access to the cable port 136. As can be appreciated by reference to the drawings, the locking clip assembly 130 includes a pivotable member 132 that is movably secured at a base 134 adjacent to the cable port 26 defined in the first housing component 20. In this version, the housing component 20 also defines a cable port 136 that communicates with the cable port 26. The cable port 136 is sized and shaped to receive the flexible cable 40. The member 132 is positionable and pivotally secured at the base 134 to control access to the cable port 136. Fig.18 When in the unlocked position shown, the cable 40 can be positioned from the cable port 26 to the cable port 136, and vice versa, the cable 40 can be positioned from the cable port 136 to the cable port 26. The member 132 can also be positioned as shown. Fig.17 The locking position shown in FIG. 1 shows a locking position in which the member 132 blocks access or communication between the cable port 26 and the cable port 136. In some versions, the locking clip assembly 130 further includes one or more biasing members, such as one or more springs, to push the member 132 into position. Fig.17 Locked position shown.

[0059] Drain cleaner 10 is usually used as follows. The operator can conveniently carry the drain cleaner 10 containing the drain cleaning cable 40 to the position of the drain pipe blockage or other problems by the handle 60. If the distal end 44 of the cable 40 is fastened to the housing of the drain cleaner 10, for example, by the locking clamp assembly 130, the member 132 pivots to its unlocked position. The cable 40 is then repositioned to the cable port 26 from the cable port 136. At this position, the cable 40 can be axially displaced relative to the drain cleaner 10. A rotary power source (such as a handheld drill) is engaged to the distal end of the drive shaft 52, and the distal end of the drive shaft 52 can be accessed along the outside of the drain cleaner 10. Then, the operator manually pulls the cable 40 out of the drain cleaner 10 and inserts the distal end 44 of the cable 40 (the tool is usually attached to the distal end 44 of the cable 40) into a pipe or other member. The rotation of the tool is performed by the actuation of the rotary power source (such as the drill). The operator can then push or otherwise displace the distal end 44 of the tool and cable 40 into the pipe until the blockage or other obstruction is cleared. The drain cleaning cable 40 can be conveniently wound within the interior area 34 of the drain cleaner 10 by the operator pushing the cable in and through the cable port. The conduit 120 rotates within the interior area 34 and guides the cable 40 into a neatly coiled stacked arrangement. After returning all or part of the drain cleaning cable 40 to the interior area 34 of the drain cleaner 10, the cable 40 can be securely fixed to the housing 20 by placing the cable 40 in the cable port 136 and locking the clamp assembly 130.

[0060] Figures 22 to 36Another embodiment of a drain cleaner 210 according to the present subject is shown. The drain cleaner 210 includes a first housing member or top housing member 220, and a second housing member or bottom housing member 230. The size and shape of the top housing member 220 and the bottom housing member 230 are designed to engage with each other in a cooperative manner to define a substantially closed hollow interior region 234. The present subject includes embodiments utilizing a single or integral housing (i.e., without multiple housing members). The resulting housing is generally annular in shape. One or more portions of a flexible shaft drain cleaning cable 240 are at least partially disposed within the interior region 234. Typically, the flexible cable 240 defines a proximal end and an opposite distal end 244 located within the interior 234. Many of the accompanying drawings show an optional tool 300 coupled to the distal end 244 of the cable 240. The drain cleaner 210 also includes a rotating power shaft assembly 250, which is generally supported by one or both of the top housing member 220 and the bottom housing member 230. Drain cleaner 210 may also include one or more handles and / or gripping members for the convenience of operator carrying and / or use. In the illustrated embodiment, drain cleaner 210 includes handle 260. As described in more detail herein, drain cleaner 210 also includes inner cone support member 270 as described above, which facilitates the management of flexible cable 240 in the inner area 234 of drain cleaner 210. In addition, in addition to the first and second cone areas defined by the first and second cone areas 74 and 80 above, inner cone support member 270 may also include flat area 271. Drain cleaner 210 also includes a cable clamp mounting assembly (not shown) disposed in the inner area 234 of drain cleaner 210 as described above. As described in more detail above herein, the cable clamp mounting assembly supports the rotary power shaft assembly 250 and directs the proximal end of the flexible cable 240 to improve engagement with the rotary power shaft assembly 250.

[0061] With further reference to the drawings, the first housing member 220 and the second housing member 230 are fixed or otherwise secured to one another. In the depicted embodiment 210, a plurality of fasteners 236 are used to releasably engage the first housing member 220 and the second housing member 230 together. As will be appreciated, holes can be defined in the first housing member 220 and in corresponding receiving members disposed in the second housing member 230. The holes and receiving members are aligned and adapted to engageably receive the fasteners 236. As will be appreciated, other configurations and / or components can be used to secure the first housing member 220 and the second housing member 230 together. As also previously described, the subject matter includes the use of a single housing, rather than multiple housing members that are fixed or engaged together.

[0062] The drain cleaner 210 also defines a channel 228 in one or both of the first housing member 220 and the second housing member 230, through which the rotary power shaft assembly 250 can be accessed. In the described embodiment 210, the channel 228 is in the form of an opening in the first housing member 220, and the size and shape of the first housing member 220 are designed to be able to engage with the rotary power shaft assembly 250. As described in more detail herein, the channel 228 is configured to allow convenient access to the outwardly extending drive shaft 252 of the rotary power shaft assembly 250. In some versions, the channel 228 is also configured to allow for ready engagement with the drive shaft 252, which extends outward at an acute angle or an angle of 0 to 90 degrees and including 0 and 90 degrees relative to a plane that generally bisects the housing members 220, 230, and is generally parallel to the interface of the housing members 20, 30. It is understood that the present subject matter includes various arrangements and orientations of the channel 228 and the drive shaft 252. For example, in some versions, the drive shaft 252 can extend outwardly in a direction parallel to the plane. In this configuration, the angle is 0 degrees. In another example, the drive shaft 252 can extend outwardly in a direction transverse to the plane. In this configuration, the angle is 90 degrees.

[0063] The drain cleaner 210 defines a centrally located opening 330, the size and shape of the opening 33 being designed to cooperate with the removable housing cover 310. The opening 330 is generally defined in the first housing or top housing 220. As described in more detail herein, the housing cover 310 allows and / or facilitates the insertion and fixation of the distal end of the tool and drain cleaning cable in the housing during the transportation of the drain cleaner 210. When it is necessary to use the drain cleaner 210, the housing cover 310 is removed from the housing so that the internal area 234 can be more easily accessed and the distal end 244 of the tool and drain cleaning cable 240 can be removed. The tool and cable end pass through the central hole defined in the housing cover 310. As described herein, the central hole is referred to as the cable outlet or cable port 226. Then, the housing cover 310 is reengaged with the drain cleaner housing 220. Figure 30 to Figure 31The housing cover 310 shown separately in the figure is configured to be selectively removed from the housing (usually the first housing or the top housing 220). The periphery of the housing cover 310 can be in various shapes, such as circular, oval, square, rectangular, triangular or polygonal. In the embodiment shown in the drawings, the housing cover 310 defines at least one generally circular outer edge 312 and a flange 313 extending outwardly, separating an outer surface 314 from an inner surface 316 in the opposite direction. In this version, the opening 330 defined in the first housing or the top housing 220 is also generally circular. Typically, the size or maximum span of the opening 330 is designed to receive and accommodate the outer edge 312 of the housing cover 310. The flange 313 extends outwardly a certain distance so that the maximum span of the cover 310 obtained between the relative positions on the flange 313 is greater than the maximum span of the opening 330. As will be understood, this configuration prevents the accidental insertion of the housing cover 310 through the opening 330. As explained in greater detail herein, housing cover 310 can be removed and / or disengaged from drain cleaner 210 housing by partially rotating within opening 330 to enable removal of cover 310. Upon such removal, exposed opening 330 enables easier access to interior 234 of drain cleaner 210.

[0064] In certain embodiments, specific ratios are used for the size of the opening of the cable outlet or port, the internal headroom height of the inner cone support member, and the outer diameter of the drain cleaning cable. Fig.31 , shows the opening span S, which represents the maximum size of the cable outlet (e.g., cable outlet 226) opening. For versions where the cable outlet 226 is circular, the opening span S corresponds to the diameter of the opening. The internal clearance height of the inner cone support member (e.g., support member 70) is Fig.36 270 to the housing cover 310. The inner headroom W is measured from the top or vertex of the inner cone support member 270 to the opening 226 of the cable outlet defined in the housing cover 310. As will be appreciated, the outer diameter D of the drain cleaning cable, such as cable 240, generally corresponds to the outer diameter of the sheath surrounding the inner cable. It is beneficial to utilize a specific ratio between S, W and D and promote the ease of use and operability of the drain cleaner. The preferred ratio between the opening span S and the cable diameter D is about 2 to about 8, and most preferably about 4 to about 6.75. The preferred ratio between the headroom W and the cable diameter D is about 2 to about 6, and most preferably about 3.3. The preferred ratio of the headroom W and the opening span S is about 0.3 to about 1.0, and most preferably about 0.6. It will be appreciated that the present subject matter is not limited to any one of these ratios, and includes various ratios outside these ranges.

[0065] In some versions of housing cover 310, cover 310 includes at least one gripping member to facilitate removal of cover 310 from the housing of drain cleaner 210. Figure 30 to Figure 31 In the illustrated version of the cover 310, the cover 310 includes a first recess or gripping member 320 that is positioned relative to the outer surface 314. The cover 310 also includes a second recess or gripping member 322 that is generally located opposite the first recess such that the cable outlet or cable port 226 is located between the two recesses 320, 322. It will be appreciated that the subject matter includes various components, configurations, and arrangements for one or more gripping members.

[0066] As previously described, the housing cover component 310 defines a centrally located cable outlet or port 226 that provides access to the interior area 234 defined by the housing components 220, 230. In some versions, the housing cover 310 further defines a tapered bevel area 224 that extends around the cable outlet or cable port 226. The tapered bevel area 224 can be in the form of a funnel or depression along an outer surface 314 of the housing cover 310 that extends around the periphery of the cable outlet 226. As described in more detail herein, when the flexible cable 240 is placed within the interior area 234 of the drain cleaner 210, the distal end 244 and a portion of the cable 240 can extend through the cable outlet 226. The tapered area 224 promotes and / or facilitates cable feeding, cable retrieval, or other one or more cable management operations.

[0067] In some versions, drain cleaner 210 includes one or more locking assemblies that secure or further secure housing cover 310 to the housing, which is typically first housing component 220. Specifically, after housing cover 310 is placed in opening 330 and housing cover 310 is positioned in a locked position ( Fig.32 330), the locking assembly secures the housing cover 310 within the opening 330. Specifically, when the housing cover 310 is initially placed in the opening 330, the rotational position of the cover 310 is generally in the unlocked or "U" position. Fig.32 310 is secured and engaged to the housing member 220 by rotating the housing cover 310 in the direction of arrow A. The housing cover 310 is removed from the housing member 220 by rotating the housing cover 310 toward the unlocked "U" position (i.e., in the direction of arrow B). In the unlocked position, as shown in the position "U", the housing cover 310 can be removed from the housing member 22, i.e., separated. After such removal, the opening 330 provides access to the interior 234 of the drain cleaner 210. After the housing cover 310 is aligned and placed in the opening 330, and the housing cover 310 is rotated to the locked "L" position, the housing cover 310 is securely fixed to the housing.

[0068] A variety of configurations and / or components can be used for a locking assembly that selectively secures and engages the housing cover 310 to the housing of the drain cleaner 210. In certain versions, the locking assembly includes at least one and typically a plurality of flexible tabs 340 extending outwardly from an outer edge 312 of the housing cover 310. A corresponding number of tab receiving areas 345 are defined in an opening 330 of the housing (e.g., housing component 220) of the drain cleaner 210. The tab receiving areas 345 are positioned along the opening 330 to receive and accept the tabs 340 of the housing cover 310 after the cover 310 is aligned with the opening 330. By reference to Figure 30 to Figure 33 It will be appreciated that after the housing cover 310 is properly aligned with the opening 330 and the tab 340 is inserted into the tab receiving area 345 and finally inserted into the interior 234 of the drain cleaner, the cover 310 can be properly positioned relative to the housing. Fig.32 The unlocked position U is shown. When the cover 310 is rotated relative to the housing to the locked position L, the tab 340 is rotatably slidable along the inner surface of the housing and thereby securely fixes the cover 310 to the housing.

[0069] As described above, various techniques and configurations may be used to enable selective engagement and / or removal of the housing cover 310 from the housing. Figure 32 to Figure 35 2 shows a series of operations for unlocking and removing the housing cover 310 from the drain cleaner 210, and thereby releasing and / or exposing the distal end 244 of the drain cleaning cable 240 for subsequent use. Specifically, after the housing cover 310 is engaged and positioned in the locked position L, the user rotates the cover 310 to the position shown in FIG. Fig.32 The unlocked position U is shown. Then, Fig.33 As shown, the user removes the cover 310 from the housing and the opening 330 defined in the housing. The interior 234 of the drain cleaner 210 can then be easily accessed. Fig.34 As shown, the user can extend his hand through the opening 330 into the interior area 234 and grasp the distal end 244 of the drain cleaning cable 240, and then, as shown in FIG. Fig.35 As shown, the user positions the distal end 244 of the cable 240 through the cable outlet 226 defined in the cover 310. The cover 310 can then be secured to the housing as previously described herein.

[0070] In certain embodiments, the drain cleaner can include onboard tool storage. Fig.23, a tool securing member 400 is formed or otherwise disposed in a housing or housing component (e.g., the first housing component 220). The member 400 can be accessed along an outer area of ​​the housing or housing component. The member 400 is configured to receive and releasably secure a tool located therein. Although various releasable retaining assemblies and / or configurations may be used, a non-limiting example is the use of one or more friction engagement members that deform when the tool is inserted or placed in the tool. The present subject matter also includes one or more tools 402 for placement and storage with the member 400. Non-limiting examples of such tools include one or more hexagonal tools, one or more screwdrivers, and one or more clamping tools (e.g., pliers).

[0071] Many other benefits will undoubtedly become apparent depending on future applications and developments of the technology.
