In general, a variety of apparatuses and assemblies can be used to clean a surface, including, but not limited to, wipes, towels, and/or mops. With respect to mops, cleaning typically involves wetting and re-wetting a mop head in a bucket and wringing the mop head over the bucket before and/or after using the mop head to clean a surface of a floor.

There have been many attempts to create mop assemblies for cleaning. However, these mop assemblies may be problematic, because they may be inefficient by requiring a mop user to move the mop head between buckets and/or different portions of a bucket. Additionally, certain mop assemblies may be problematic because they require a mop assembly user to constantly bend over every time he/she has to wring out the mop, either physically by hand or with a lever to squeeze out the water, causing discomfort to the mop assembly user. Therefore, there is a need for a user friend mop assembly that allows a mop assembly user to wet, wring out, and re-wet the mop head in an efficient and comfortable manner. SUMMARY

DETAILED DESCRIPTION

This disclosure provides apparatuses and assemblies for cleaning a surface. In describing examples and exemplary embodiments shown in the Figures, specific terminology may be employed for the sake of clarity. However, this disclosure should not be limited to the specific terminology so selected, and it should be understood that each specific element includes all technical equivalents that may operate in a similar manner.

Referring now to the Figures, wherein like reference numerals designate identical or corresponding parts throughout the several views, Figures 1 and 2 show a mop bucket assembly 10, according to an exemplary embodiment. The mop bucket assembly 10 may be any apparatus that may be configured to allow for wetting, wringing out, and re-wetting of a mop therein. Figure 1 shows that the mop bucket assembly 10 may include a rim 12, a basket 14, a supporting member 16, and a bucket 18. Figures 1 and 8 illustrate that the bucket 18 may include a handle 181. The mop bucket 18 and the handle 181 may be made of any desired material and may each be any size, shape, and/or configuration such that when a liquid is contained within the bucket 18, a user may hold the bucket 18 with the handle 181.

The rim 12 may be sized, shaped, and/or configured to cooperate with an open end 18a of the bucket 18. In some embodiments the rim 12 may be integral with the open end 18a of the bucket 18. Alternatively, in some embodiments, the rim 12 may be configured to removably engage the open end 18a of the bucket 18. The rim 12 may removably engage the open end 18a of the bucket 18 via any engagement mechanism known to those skilled in the art. For example, Figure 3 shows that the rim 12 may include one or more tabs 124 and/or openings 126 that may be configured to engage one or more corresponding features on the open end 18a of the bucket 18.

Figure 3 shows that the rim 12 may include one or more indentations 122. The one or more indentations 122 may be sized, shaped, and/or configured as a spout, having an angled portion, such that a user may easily pour a liquid out of the bucket 18. In some embodiments, the rim 12 may include a single indentation 122 (see Figure 3 ) . Alternatively, in some embodiments, the rim 12 may include a plurality of indentations 122 spaced around the rim 12, such that a mop bucket assembly user may be configured to easily pour liquid out of the bucket 18 from a plurality of locations at the open end 18a of the bucket 18.

As previously discussed, the mop bucket assembly 10 may include a basket 14. Figure 2 shows that the basket may be sized, shaped, and/or configured to fit within an interior of the bucket 18. The basket 14 may further be sized, shaped, and/or configured to rotate within the bucket 18. As shown in Figures 4 and 5, the basket 14 may include a plurality of openings 146. The plurality of openings 146 may be any size and/or shape so long as they may be configured to enable a liquid to pass therethrough. In some embodiments, the basket 14 may include one or more mop head retaining means 142. The mop head retaining means 142 may be any mechanism that may be configured to retain a mop head in a portion of the basket 14 and substantially prevent the mop head from moving relative to the basket 14. For example, in some embodiments, as illustrated in Figures 4 and 5, the mop head retaining means 142 may include a plurality of ribs circumferentially spaced around an interior portion of the basket 14. The ribs may be configured to engage at least a portion of the mop head by applying a friction and/or radial clamping force on the mop head. For example, in some embodiments, the ribs 142 may include a deformable material that may be configured to radially clamp onto a portion of the mop head 28 in response to insertion of the mop head 28 in the basket 14. Figures 4 and 5 illustrate that the ribs extend vertically within the interior portion of the basket 14. In other embodiments, the ribs may extend in any direction within the basket 14 so long as the ribs may be configured to exert a clamping force on the mop head. Figures 4 and 5 also illustrate an embodiment including five (5) ribs. Alternative embodiments may include any desired number of ribs so long as the ribs may be configured to substantially prevent the mop head from rotating relative to the basket 14.

In addition to the mop head retaining means 142, the basket 14 may include a central portion 144 that may be any desired size, shape, and/or configuration so long as it may be configured to removably engage the mop head 28 (see Figures 11 and 12) . For example, in some embodiments, such as those illustrated in Figures 4 and 5, the central portion 144 of the basket 14 may include a single cylindrical 145 projection. Figures 11 and 12 show that the cylindrical projection 145 of the central portion 144 of the basket 14 may be configured to engage a corresponding opening 225 in a bottom portion 223 of a base 221 of the mop head 22. In alternative embodiments, the central portion 144 of the basket 14 may contain a plurality of cylindrical projections (not shown) that may be configured to engage a corresponding number of openings in the bottom portion 223 of the mop head 22.

In some embodiments, the central portion 144 of the basket 14 may be configured to rotatably engage a supporting member 16 that may be located in an interior portion 184 of the bucket 18. As illustrated in Figures 6 and 7, in some embodiments, the supporting member 16 may include a central protrusion 162. The central portion 144 of the basket 14 may be sized, shaped and/or configured to rotatably engage the central protrusion 162 of the supporting member 16 in a manner such that the basket 14 may be configured to rotate about the central protrusion 162 of the supporting member 16 with respect to the bucket 18. For example, as illustrated in Figure 12, in some embodiments the central portion 144 of the basket 14 may include a recess 147 on the underside thereof. As illustrated in Figure 12, the recess 147 on the underside of the central portion 144 of the basket 14 may be configured to engage the central protrusion 162 of the supporting member 16. In alterative embodiments the central protrusion 162 of the supporting member 16 may include an upward facing recess (not shown) and the central portion 144 of the basket 14 may include downward facing projection configured to engage the recess such that the basket 14 may be configured to rotate about the central protrusion 162 of the supporting member 16 with respect to the bucket 18.

In some embodiments the supporting member 16 may include one or more arms 164 extending from a base of the central protrusion 162. The one or more arms 164 may be any size, shape, and/or configuration so long as they may be configured to engage an interior portion 184 of the bucket 18 in a rotationally locked relationship such that the supporting member 16 may be substantially prevented from rotating relative to the bucket. Figures 6 and 7 illustrate an embodiment where the supporting member 16 includes three arms 164. Alternative embodiments may include any desired number of arms so long as the supporting member 16 may be configured to fit within and engage the interior portion 184 of the bucket 18.

The one or more arms 164 and the interior portion 184 of the bucket 18 may include corresponding engagement components. For example, the one or more arms 164 may be configured to engage the interior portion 184 of the bucket 18 via a snap fit, friction fit, threading, and/or any other type of engagement known to those skilled in the art. In some embodiments, the engagement components may be configured such that when the one or more arms 164 engage the interior portion 184 of the bucket 18, the supporting member 16 may be configured to maintain a single position with respect to the vertical axis in the interior portion 184 of the bucket 18, for example, when liquid drains from and/or is not in the mop bucket 18.

Alternatively, in some embodiments, the engagement components may be configured such that when the one or more arms 164 engage the interior portion 184 of the bucket 18, the supporting member 16 may be configured to move in a vertical direction along the longitudinal axis of the interior portion 184 of the bucket 18. For example, in some embodiments and as shown in Figures 6 and 7, the one or more arms 164 may each include a projection 166 extending from an end thereof. Figure 10 illustrates that each projection 164 may be configured to engage a respective track 182 located on a surface of the interior portion 184 of the bucket 18. As illustrated in Figure 9, each track 182 may extend vertically along the length of the interior portion 184 of the bucket 18. The projections 164 may be configured to engage each respective track 182 in a manner such that the supporting member 16 may be configured to transition up and down in a vertical direction within the bucket 18 and along the track 182. Figure 9 illustrates that each track 182 may include a stop 186. The stop 186 may include a notch portion 188. In some embodiments, the projection 166 on the arm 164 of the supporting member 16 may be configured to engage the notch portion 188 of the track 182 when the supporting member 16 is moved in a vertical direction. For example, as illustrated in Figure 10, in some embodiments, the supporting member 16 may be configured to maintain a position between the top and bottom of the bucket 18 when each projection 166 engages with a respective notch portion 188 on the track.

Each stop 186 may be positioned on each respective track 182 such that when the projections 166 engage the respective notch portions 188, the supporting member 16 may be configured to maintain the basket 14 at a position above liquid within the bucket 18. Each stop 186 may also be positioned on each respective track 182 based on the size of the basket 14 and/or the size of the bucket 18. For example, in some embodiments the stop 186 may be positioned along the track 182 such that when the basket 14 is rotatably engaged with the central protrusion 162 of the support member 16 and when the projections 166 are located within the notch portions 188, the basket 14 may substantially be positioned within the interior 184 of the bucket 18 such that the basket 14 does not extend beyond the open end 183 of the mop bucket 18 (see e.g., Figure 11) .

Figure 9 illustrates that the notch portion 188 may be accessed via one or more access paths 189a, 189b that may be positioned along the track 182 and within the stop 186. The one or more access paths may be sized, shaped, and/or configured such that each projection 166 may be configured to have access in and out of each respective notch portion 188. For example, as illustrated in Figure 9, in some embodiments, the track 182 may include a first access path 189a and a second access path 189b. The first and second access paths 189a, 189b may be separated by at least one rail 187. The at least one rail 187 may be configured to define an edge of each of the first and second access paths 189a, 189b. The rail 187 may be positioned along the track 182 and within the stop 186 such that when the supporting member 16 transitions in a vertical direction from a position below the stop 186 towards the top of the mop bucket 18, a projection 166 engaging the track 182 may be configured to abut the rail 187 and access the notch portion 188 via the first access path 189a.

The rail 187 may further be positioned such that the projection 166 may be configured to exit the notch portion 188 via the second access path 189b. The second access path 189b may be in communication with the track 182 such that when the projections 166 exit their respective notch portions 188 along their respective second access paths 189b, the supporting member 16 may be configured to transition in a vertical direction from the stop 186 to a position below the stop 186 towards the bottom of the bucket 18.

In addition to being configured to transition along the track 182 in a vertical direction towards the bottom of the mop bucket 18, the supporting member 16 may be configured to transition along the track 182 in a vertical direction towards the top of the mop bucket 18. Transition of the supporting member 16 in this manner may be desired, for example, when a user removes the basket 14 and supporting member 16 from the mop bucket 18 in order to clean the mop bucket 18 or to empty liquid or water from the mop bucket 18.

In the embodiments discussed herein, the projections 166 may not be limited to accessing the respective notch portions 188 via the first access path 189a and exiting the respective notch portions 188 via the second access path 189b. Rather, the projections 166 may be configured to access and exit the respective notch portions 188 via any of the first and second access paths 189a, 189b. Figure 11 illustrates a mop assembly 20 that may be configured to interact with the mop bucket assembly 10. As shown in Figure 13, the mop assembly 20 may include a mop head 22. In some embodiments, the mop head 22 may be sized, shaped, and/or configured to be positioned within the bucket 18 and the basket 14. For example, the mop head 22 may be sized and shaped such that it may be configured to be inserted through the open end 18a of the bucket 18, and further such that it may be configured to fit within the interior of the basket 14.

The mop head 22 may include a connector portion 222 and a base portion 221. As previously discussed, the base portion 221 may be configured to engage the central portion 144 of the basket 14, as shown in Figures 11 and 12. In addition, Figure 13 shows that the base portion 221 may be configured to engage a mop portion 24. The mop portion 24 may include a mop ring 241 that may be configured to engage the bottom portion 223 of the base portion 221 via any engaging means known to those skilled in the art, including, but not limited to a snap fit and/or a friction fit. In some embodiment, as shown in Figure 13, the mop ring 241 may be configured to engage a material 242 that may be configured to absorb liquid and clean a surface. The material 242 may include, but is not limited to cloth or a sponge. In some embodiments, such as the embodiment shown in Figure 13, the material 242 may be strips of cloth that may be configured to be woven through at least a portion of the mop ring 241.

The base portion 221 may be configured to angularly move about the connector portion 222. As illustrated in Figures 12 and 13, the connector portion 222 may extend from a top 224 of the base portion 221 and may be configured to removably engage an end 202 of the mop handle 20 via any engagement means known to those skilled in the art, including, but not limited to, a snap fit and a friction fit. In some embodiments, as illustrated in Figure 18, the connector portion 222 may be configured to engage the end 202 of the mop handle 20 via threading . Figures 11 and 12 illustrate that the mop handle 20 may be configured to extend from the connector portion 222 of the mop head 22. In some embodiments, the mop handle 20 may include at least two telescoping pieces 201, 203. For example, as illustrated in Figure 13, the mop handle 20 may include a first telescoping piece 201 and a second telescoping piece 203 In some embodiments, each telescoping piece 201, 203 may be a single hollow piece. Alternatively, in some embodiments, as illustrated in Figure 13, at least one of the telescoping pieces 201 may include a plurality of hollow interconnected pieces 201a, 201b. For example, in one embodiment, the first telescoping piece 201 may include two interconnecting pieces 201a, 201b. The interconnecting pieces 201a, 201b may be configured to engage via any connection means known to those skilled in the art, including, but not limited to, a snap fit or a friction fit. Alternatively, or in addition, in some embodiments, and as shown in Figure 18, the interconnecting pieces 201a, 201b may be configured to engage via threading.

Figures 11 and 13 further illustrate that the first telescoping piece 201 may include one or more gripping portions 205, 207. The one or more gripping portions 205, 207 may each include surfaces that allow for a mop assembly user to grip the mop assembly 20 during use, and may be of any design known to one of ordinary skill in the art.

Figures 11 and 13 further illustrate that in some embodiments the mop handle 20 may include a locking mechanism 209. The locking mechanism 209 may be configured to maintain the first telescoping piece 201 in a selected position relative to the second telescoping piece 203. In some embodiments, the locking mechanism 209 may be configured such that when the locking mechanism 209 is engaged, the first and second telescoping pieces 201, 203 remain in a substantially fixed position relative to one another, and such that when the locking mechanism 209 is disengaged, the first and second telescoping pieces 201, 203 may move relative to one another along a longitudinal axis of the mop handle 20. Additionally, the locking mechanism 209 may be configured such that when the locking mechanism 209 is disengaged, the first and second telescoping pieces 201, 203 may rotate with respect to one another.

The locking mechanism 209 may be configured to fix the first and second telescoping pieces 201, 203 relative to one another via application of a circumferential compression force. The compression force may be applied to the first and/or second telescoping pieces 201, 203 in manner such that when the compression force is above a predetermined threshold, the first and second telescoping pieces 201, 203 compress relative to one another such that the first telescoping piece 201 is substantially prevented from moving relative to the second telescoping piece 203. Accordingly, the locking mechanism 209 may be designed to include any components known to those skilled in the art that, when engaged, may be configured to exert the compression force described herein on the first and second telescoping pieces 201, 203 and when disengaged, may be configured to release the compression force. In some embodiments, the locking mechanism may include a system of two or more hollow sleeves configured move relative to one another (rotatably or longitudinally) and transition the first and second telescoping pieces 201, 203 from a fixed position to a non-fixed, telescoping position. Alternatively, in some embodiments, and as shown in Figures 11 and 13, the locking mechanism 209 may include a lever 208 that may be configured to transition from a locked and engaged position to an unlocked and disengaged position.

Figure 18 illustrates that in some embodiments, the mop handle 20 may additionally include an internal rotating mechanism 26 therein which may be configured to cause the second telescoping piece 203 to rotate when the first telescoping piece 201 is pushed and/or moved downward towards the mop head 22. The rotating mechanism 26 may be configured such that when the locking mechanism 209 is disengaged and a downward force is applied to the first telescoping piece 201, the second telescoping piece 203 may be configured to rotate. The rotating mechanism 26 may further be configured to translate rotational forces to the mop head 22 and to the basket 14. For example, when a user engages the bottom 225 of the mop base 221 with the central portion 144 of the basket 14 in the mop bucket 18 and applies a downward force on the first telescoping piece 201, simultaneous rotation of the second telescoping piece 203, the mop head 22, and the basket 14 may result in a manner described herein.

Translation of rotational forces via the rotating mechanism 26 may be accomplished by engagement of the rotating mechanism 26 with each of the first and second telescoping pieces 201, 203. The first telescoping piece 201 may include two pieces -- an upper piece 201a and a lower piece 201b -- that interconnect and may disconnect for ease of storage. For example, as shown in Figure 18, in some embodiments, the rotating mechanism 26 may be configured to extend between and within the first and second telescoping pieces 201, 203 such that at least a portion 262 of the rotating mechanism 26 may be configured to engage the lower first telescoping piece 201b, and at least a portion 266 of the rotating mechanism 26 may be configured to engage the second telescoping piece 203 in a manner described herein.

Figures 16 and 17 illustrate that the rotating mechanism 26 may include an elongate rod 261. The elongate rod 261 may be sized, shaped, and/or configured to extend between the first telescoping piece 201 and the second telescoping piece 203. Figures 16 and 17 additionally illustrate that the rod 261 may include a plug 262 at an end thereof. The plug 262 may be sized, shaped, and/or configured such that it may be the portion 262 of the rotating mechanism 26 that may be configured to engage the first telescoping piece 201. For example, as shown in Figure 18, the plug 26 may be configured to engage the interior portion of the first telescoping piece 201b. The plug 262 may be configured to engage the interior portion of the lower first telescoping piece 201b via any engagement means known to those skilled in the art, including, but not limited to, snap fit, friction fit, or threading. In some embodiments, the plug 262 may be configured to cooperate with the end of the rod 261 such that when the plug 262 engages the interior portion of the lower first telescoping piece 201b, the rod 261 may remain in a fixed position relative to the first telescoping piece 201. Figures 14 and 16 illustrate that in some embodiments of the rotating mechanism 26, 26', the end of the rod 261 may be configured to extend beyond a top end of plug 262, 262' . Alternatively, in other embodiments of the rotating mechanism 26'', such as the embodiment of Figure 15, the plug 262'' may be configured to substantially cover the end of the rod 261.

Figures 15 and 16 illustrate that in some embodiments, the rotating mechanism 26 may further include a hollow tube 265. In some embodiments, the hollow tube 265 may be the portion of the rotating mechanism 26 that may be configured to engage the second telescoping piece 203 such that when the hollow tube 265 engages the second telescoping piece 203, the hollow tube 265 may remain in a substantially fixed position relative to the second telescoping piece 203.

Figures 14 and 18 illustrate exemplary embodiments of the hollow tube 265 engaged with the second telescoping piece 203. For example, Figures 14 and 18 illustrate that in some embodiments, the hollow tube 265 may include a cuff 266 at an end thereof that may be configured to engage an end of the second telescoping piece 203. As illustrated in Figures 14 and 18, the cuff 266 may be sized, shaped, and/or configured such that when the hollow tube 265 is inserted into the second telescoping piece 203, the cuff 266 may be configured to engage the end of the second telescoping piece 203 via engagement means that include, but are not limited to, snap fit, friction fit, and/or threading. The hollow tube 265 may be configured such that the rod 261 may engage and translate in a co-linear direction within a hollow tube 265. For example, in some embodiments, the rod 261 may be configured to engage an interior portion 268 of the hollow tube 265 via a rotational end piece 28. Figures 17-19 illustrate that in some embodiments, the rotational end piece 28 may be positioned at a second end portion of the rod 261 opposite the plug 262. The rotational end piece 28 may be configured such that it may rotate about the second end of the rod 261.

As illustrated in Figures 17-19, the rotational end piece 28 may include a plurality of projections 281. Figures 18 and 19 illustrate that the plurality of projections 281 may be configured to engage a spiral track 268 extending along an interior portion for the hollow tube 265. The plurality of projections 281 may be sized, shaped, and/or configured such that when a linear force is applied to the rod 261, the plurality of projections 281 on the rotational end piece 28 may be configured to engage the spiral track 268 and translate in a linear direction along the spiral track 268.

The plurality of projections 281 may further be sized, shaped, and/or configured such that when a linear force is applied to the rod 261 that causes the first telescoping piece 201 to move in a downward direction towards the mop base 22, the rotational end piece 28 may be configured cause rotation of hollow tube 265 in a first direction relative to and about the rod 261. Moreover, the plurality of projections may be sized, shaped, and/or configured such that when a linear force is applied to the rod 261 that causes the first telescoping piece 201 to move in an upward direction away from the mop base 22, the rotational end piece 28 may be configured to rotate about the rod 261 in a second direction, opposite the first direction, without causing rotation of the hollow tube 265.

The rotational end piece 28 may be configured to cause rotation of the hollow tube 265 in the first direction and not in the second direction, i.e., in only one direction, via the aid of a clutch mechanism 30. For example, Figures 17-19 illustrate a clutch mechanism 30, according to an exemplary embodiment. As illustrated in Figures 17-19, the clutch mechanism may be positioned circumferentially about the rod 261 and may include a plurality of teeth 301 that may be configured to engage a plurality of corresponding teeth 282 extending from the rotational end piece 28. In some embodiments, the clutch mechanism 30 may be fixed relative to the rod 261, and the rotational end piece 28 may be configured to transition linearly along at least a portion of the rod 261 and rotated about the rod 261. For example, in some embodiments, the rotational end piece 28 may be configured to transition between a first position, where its teeth 282 are engaged with the teeth 301 of the clutch mechanism 30 (e.g., Figures 18 and 19) and a second position, where its teeth 282 are disengaged from the teeth 301 of the clutch mechanism 30 (e.g., Figure 17) .

Figures 18 and 19 illustrate the rotational end piece 28 in the first position. In some embodiments, the rotational end piece 28 may be placed in the first position when the rod 261 is moved linearly downward toward the mop head 22 and the projections 281 of the rotational end piece 28 engage the spiral track 268 in the hollow tube 165. When the rotational end piece 28 is in the first position, the rotational end piece 28 may be substantially prevented from rotating about the rod 261. As such, when the rotational end piece 28 is in the first position and the rod 261 is moved downward towards the mop head 22, movement of the projections 281 of the rotational end piece 28 along the spiral track 268 results in rotational movement of the hollow tube 265 in the first direction .

Figure 17 illustrates the rotational end piece 28 in the second position. The rotational end piece 28 may be placed in the second position when the rod 261 is moved linearly upward, away from the mop head 22 and the projections 281 of the rotational end piece 28 engage the spiral track 268 of the hollow tube 265. When the rotational end piece 28 is placed in the second position, the rotational end piece 28 may be spaced apart from the clutch mechanism 30 such that the rotational end piece 38 may be configured to rotate about the rod 261. As such, when the rotational end piece 28 is in the second position and the rod 261 is moved linearly upwards, away from the mop head 22, movement of the projections 281 along the spiral track 268 results in rotational movement of the rotational end piece 28 without causing rotation of the hollow tube 265.

In some embodiments, such as the embodiment of Figures 16-19, the clutch mechanism 30 may be sized, shaped, and/or configured such that it may be fixed to the plug 262 and extend along and about the rod 261 to a position within the hollow tube 265 (see Figures 16 and 18) . Alternatively, in some embodiments, such as the embodiments of Figures 14 and 15, the clutch mechanism (not shown) may be sized, shaped, and/or configured such that it may be fixed to a first portion of the rod 261 within the hollow tube 265 and may extend to a second portion of the rod 261 within the hollow tube 265. Figure 16 further illustrates that the rotational mechanism 26 may include a biasing member 263, such as a spring. The biasing member 263 may be configured to bias the rotational mechanism 26 in an extended position, such that a mop assembly user may quickly, easily, and/or efficiently transition the first telescoping piece 201 linearly up and down relative to the second telescoping piece 203.

As illustrated in Figure 17, the biasing member 263 may be configured to extend around and along the rod 261. In some embodiments of the rotational mechanism 26', 26'', such as those illustrated in Figures 14 and 15, the biasing member 263', 263'' may be sized, shaped, and/or configured to extend directly around and along the rod 261. Alternatively, in some embodiments, such as the embodiment of Figures 16 and 17, the biasing member 263 may be sized, shaped and/or configured to extend around and along the clutch mechanism 30 that may be positioned around and along the rod 261.

Figures 16 and 17 further illustrate that the biasing member 263 may be any size, shape, and/or configuration such that it may be configured to engage and extend from a bottom end of the plug 261 to a position between the bottom end of the plug 262 and the top end of the cuff 266. For example, in some embodiments, such as the embodiments of Figures 14 and 16-17, the biasing member 263, 263' may be configured to extend to a position that may be adjacent to a top edge of the cuff 266. Alternatively, in some embodiments, such as the embodiment of Figure 15, the biasing member 263'' may be configured to extend to a position along a middle portion of the rod 261.

The biasing member 263 may be configured to contract and expand in response to an application of a force on the first telescoping piece 201 in a linear direction. As such, in some embodiments, the rotating mechanism 26 may include one or more components that may be configured to control contraction and/or expansion of the biasing member 263. For example, in some embodiments, the rotating mechanism may include a stop 267 that may be configured to abut a top end of the cuff 266, such that when the stop 266 abuts the top end of the cuff 266 and force is applied to the first telescoping piece 201 in a linearly downward direction towards the mop head 22, the biasing member 263 may be configured to contract.

In some embodiments of the rotational mechanism 26', 26'', such as the embodiments of Figures 14 and 15, the biasing member 263', 263'' may be configured to achieve a substantially fully contracted position. Alternatively, in some embodiments, such as the embodiment of Figures 16-18, the rotating mechanism 26 may include a component 269 that may be configured to extend around both the rod 261 and the biasing member 263 such that contraction of the biasing member 263 may be configured to stop when the bottom end of the plug 262 abuts a top end of the component 269. This limits the range of linear translations of the first telescoping piece 201 with respect to the second telescoping piece 203.

In use, a user of a mop assembly and mop bucket assembly may first fill the mop bucket 18 with a liquid, such as water, up to a desired height. Then, as shown in Figures 11 and 12, while the locking mechanism 209 is in a locked position such that the first and second telescoping pieces 201, 203 are not configured to move relative to one another, the user may engage the mop head 22 with the central portion 144 of the basket 14 such that the mop head retaining means 142 may be configured to engage and exert a clamping force on the mop head 22 and such that the mop head 22 is not rotatable relative to the basket 14. The user may then apply linear forces to the mop handle 20, which may be configured to cause the supporting member 16 that supports the basket 14 to transition along the tracks 182 in the mop bucket 18 in order to place the mop head 22 and basket 14 in a desired position relative to the liquid in the mop bucket 18.

For example, in some embodiments, the user may engage the mop head 22 with the basket 14 when the projections 166 of the supporting member 16 are positioned within respective notch portions 188 of the stop 186 in the track 182. If the user desires to wet the mop head in the liquid in the mop bucket 18, the user may first apply an upwards linear force on the mop handle 20, which may be configured to disengage the projections 166 from their respective notches 188 and transition them into the track 182 via one of the access paths 189a, 189b. Then the user may apply a downward linear force on the mop handle 20, which may be configured to transition the supporting member 16 away from the open end 183 of the mop bucket 18 so that the basket 14 and mop head 22 may be immersed in the liquid in the mop bucket 18. After wetting the mop head 22, the user may want to wring out excess liquid from the material 242 of the mop 24 engaged with the mop head 22. This may be accomplished by application of an upward linear force on the mop handle 20 in order to transition the supporting member 16 upwards towards the open end 183 of the mop bucket 18. Transitioning of the supporting member 16 upwards along the tracks 182 may stop when the projections 166 enter their respective notch portions 166 via one of the access paths 189a, 189b.

After the user positions the basket 14 in the mop bucket 18 such that the projections 166 are within their respective notch portions 166, the user may unlock the locking mechanism 209 of the mop handle 20 such that the first and second telescoping pieces 201, 203 may be configured to move relative to one another, and wring out excess liquid from the material 242 of the mop 24 engaged with the mop head 22 via the application downward and upward linear forces on the first telescoping piece 201. When the user applies upward and downward linear forces on the first telescoping piece 201, the material 242 of the mop 24 engaged with the mop head 22 may be wrung out in response to the simultaneous rotation of the second telescoping piece 203, the mop head 22 and the basket 14 in a single direction about the central protrusion 162 of the support member 16. After a desired amount of liquid has been wrung out from the material 242, the user may remove the mop head 22 from the mop bucket assembly 10 by applying force on the mop handle 20 when the mop handle 20 is at a non- vertical angle relative to the mop head 22, which may cause the mop head 22 to disengage from both the central portion 144 of the basket 14 and the mop head retaining means 142 within the basket 14.

After desired use of the mop, the user may repeat the previously discussed steps in order to re-wet the material 242 and/or wring out the material 242. The user may wet, wring out, and/or re-wet the material 242 without bending down and/or removing the mop from the mop bucket 18. Accordingly, use of the mop and mop bucket 18 as discussed herein may result in wetting, wringing out, and/or re-wetting of the mop head 22 in manner that may be comfortable and efficient to the mop assembly and mop bucket user.
