The following terms are used in this specification, and unless otherwise noted or clear from the context, these terms have the meanings provided below.

“Generally planar” means that a surface is level and aligned with another surface, such that the two surfaces form a substantially flat single surface, within a tolerance of +/−0.05 inches.

In general, this disclosure relates to a grip handle assembly for a mop. In some examples, the grip handle assembly may be connected to a mop system comprising a spin mop and a bucket assembly where the spin mop engages the bucket assembly to assist in dewatering the mop. In short, when the mop head engages a wringer basket of a bucket assembly, the spinning of the mop head may cause the wringer basket to spin with it, which causes excess water to be forced from the yarns of the mop head. Therefore, dewatering the mop head and preparing it for use. The mop head may be configured to pivot along two different axes to allow a movement of the handle assembly to drive the rotation of the wringer basket even when the handle assembly is arranged at different angles relative to the mop head. In other examples, the grip handle assembly may be connected to a different type of mop such as a sponge mop or other mop know to one skilled in the art to dewater the sponge.

FIGS. 1 and 2 illustrate the grip handle assembly 100. In FIG. 1, the lever 170 is shown in an unlocked or released position, and in FIG. 2 the lever 170 is shown in a locked or engaged position. The exemplary grip handle assembly 100 may be used with a spin mop system 10 as shown in FIG. 3 that includes a spin mop 20 and a bucket assembly 30, where the spin mop 20 engages a wringer basket 35 of the bucket assembly 30 to dewater a mop head 25 of the spin mop 20. The spin mop system 10 may be similar to the spin mop system described in U.S. patent Ser. No. 17/235,679 filed on Apr. 20, 2021, which is incorporated by reference in its entirety. The spin mop 20 may include a handle assembly 40 that defines a longitudinal axis 50 of the spin mop 20. The spin mop 20 may also include a drive mechanism that comprises a spiral member 45 that is slidably engaged with the handle assembly 40 and also pivotally engaged with the mop head 25. The bucket assembly 30 may include a bucket 55 to hold a cleaning solution, and a wringer basket 35 that is rotatably engaged with an axle member of the bucket 55.

After the mop head 25 has been submerged in the cleaning solution contained in the bucket 55, the spin mop 20 may be received in and engage the wringer basket 35 to assist in dewatering the mop head 25 to ensure the mop head 25 has the desired moisture content for the intended cleaning task. The mop head 25 may be placed into the wringer basket 35. Once the mop head 25 is received in the wringer basket 35, the lever 170 may be moved (i.e. rotated or lifted) to a released position to release a brake bushing 80 that allows the handle tube 42 of the handle assembly 40 to slidably move along the spiral member 45. As the spiral member 45 rotates, the spiral member 45 causes the mop head 25 to rotate (i.e., spin). The spinning of the mop head 25 then causes the wringer basket 35 to spin in the same direction as the rotation of the mop head 25 creating a centrifugal force to cause any excess cleaning solution, or liquid, to be forced from the yarns of the mop head 25.

The handle assembly 40 may include a handle tube 42 and a grip handle assembly 100 near the lower end of the handle tube 42. The grip handle assembly 100 may include a lever 170 that is pivotally attached to the grip handle 110. The lever 170 may engage a brake bushing 80 within the grip handle 110 that engages the spiral member 45, where the lever 170 has a locked positioned that prevents the handle assembly 40 from moving relative to the spiral member 45 and an unlocked position that releases the brake bushing 80 which allows the brake bushing 80 along with the handle assembly 40 to slide downward on the spiral member 45. The lever 170 may engage the brake bushing 80 by compressing flexible fingers on the brake bushing 80 to prevent the handle tube 42 from moving relative to the spiral member 45 when in the locked position. As these components move along the spiraled surface of the spiral member 45, the spiral member 45 rotates causing the mop head 25 to spin.

The grip handle assembly 100 for the mop 20 may comprise a grip handle 110 that connects to a handle tube 42 of the mop 20 and a lever 170 that is pivotally engaged with the grip handle 110. The grip handle 110 may include a grip handle body 112 with a first end 114 and a second end 116 opposite the first end 114, wherein the grip handle body 112 has a passage 118 extending from the first end 114 to the second end 116. The grip handle 110 may further comprise a lever mount 120 nearer the first end 114 than the second end 116, where the lever mount 120 comprises a first side mount 122 extending from the grip handle body 112 and a second side mount 124 extending from the grip handle body 112 opposite the first side mount 122. An opening 126 may be located in the grip handle body 112 between the first side mount 122 and the second side mount 124. A lever stop 128 may be positioned near the first end 114 (i.e., closer to the first end 114 than the second end 116) of the grip handle body 112. In some examples, the lever stop 128 may be positioned at the first end 114 of the grip handle body 112. The lever stop 128 may include a central protrusion 130 extending from the grip handle body 112 and a first stop surface 132 and a second stop surface 134. The first stop surface 132 may be adjacent to the central protrusion 130 and located on a first side of the central protrusion 130, and the second stop surface 134 may be adjacent to the central protrusion 130 and located on a second side of the central protrusion 130 opposite the first side of the central protrusion 130. In some examples, the central protrusion 130 and first and second stop surfaces 132, 134 may be located near and/or at a front end 136 of the opening 126.

The lever 170 may be pivotally connected to the grip handle 110 at the lever mount 120. As shown in FIG. 10, the lever 170 may comprise a pair of tabs 172 extending from a lever base 174 that connect to the lever mount 120. Each tab 172 may be aligned on a lever axis. The lever 170 may further comprise a grip portion 176, a first forward stop member 178, a second forward stop member 180, and a rear stop member 182. The forward stop members 178, 180 and the rear stop member 182. The rear stop member 182 may extend into the opening 126 of the grip handle body 112.

As discussed above, the lever 170 may be moved to a released or unlocked position as shown in FIGS. 1 and 4-6, or an engaged or locked position as shown in FIGS. 2 and 7-9. When the lever 170 is in the released position, at least one of the first and second forward stop members 178, 180 of the lever 170 engages or contacts the first and second stop surfaces 132, 134 of the lever stop 128 as shown in FIG. 6. The first and second stop surfaces 132, 134 may be generally planar such that the majority of the surface area of each of the first and second stop surfaces engages 132, 134 each engaging surface of the first and second forward stop members 178, 180 of the lever 170. The engaging surface of the forward stop members 178, 180 may also be generally planar. In addition, in some examples, when the lever 170 is in the released position, the rear stop member 182 may engage or contact the grip handle body 112 near a rear end 138 of the opening 126 as shown in FIGS. 5 and 6. The grip handle 110 may also comprise an internal shelf 142 that is configured to engage and support a brake bushing 80. When the lever 170 is in the released position, the brake bushing 80 has the compression force applied by the rear stop member 182 removed to allow the handle assembly 40 and spiral member 45 to move relative to each other.

FIGS. 7-9 illustrate the grip handle assembly 100 in the locked position. When the lever 170 is in the locked position, the rear stop member 182 extends into the opening 126 and engages the flexible fingers of the brake bushing 80 which creates a clamping force onto the handle tube 42 to prevent any movement between the handle assembly 40 and the spiral member 45 as shown in FIG. 13. FIGS. 8 and 9 illustrate the first and second forward stop members 178, 180 being free of contact with the first and second stop surfaces 132, 134 of the lever stop 128. As best shown in the cross-sectional view of FIG. 9, an angle 160 between the first stop surface 132 and the surface of the first end 114 of the grip handle body 112 may be approximately 45 degrees, or within a range of 25 and 65 degrees. By utilizing the forward stop members 178, 180 on the lever 170 to contact the stop surfaces 132, 134 respectively of the grip handle body 112 and the rear stop member 182 to contact an interior surface of the grip handle body 112 near or at a rear end 138 of the opening 126, the lever 170 may withstand a maximum downward force applied by a user of approximately 50 pounds, or within a range of 45 and 50 pounds, or within a range of 40 and 50 pounds. The downward force may be tested using a force gauge that is capable of recording a pulling or pushing force. To test the maximum force capable by the lever 170, the lever 170 is moved to an unlocked position to an angle of approximately 45° to the grip handle body 112. The force gauge's peg attachment is placed against the grip portion 176 of the lever 170 that is facing the grip handle body 112. A force is then applied to lever 170 towards the mop head 25 while holding onto the gauge and the handle tube 42 until wither either the lever 170 or the grip handle 110 break in a way that allows the lever 170 to approach an angle nearly 180° from the locked position of the lever 170. The maximum force used to break the lever 170 or the grip handle 110 is recorded.

FIGS. 12 and 13 illustrate front views of the grip handle assembly 100 with the brake bushing 80 received within the grip handle 110. FIG. 13 illustrates the lever 170 in the locked position with fingers of the brake bushing 80 in a compressed state. FIG. 12 illustrates the lever 170 in an unlocked position with the fingers of the brake bushing 80 in an uncompressed state.

The various components of the grip handle assembly 100 such as the grip handle 110 and the lever 170 may be formed from a polymeric material, such as a nylon or polycarbonate, using a molding, forming, cutting, or other process known to one skilled in the art.
