  • the second pivot location 45 is located on a second side of the imaginary line 28.
  • the angle between the second extending portion 43 and the third extending portion 44 can be, for example, approximately 158 degrees.
  • the material of the first, second, and third extending portions 42, 43, 44 are preferably steel stampings providing with ribbing to increase their strength.
  • the presser member 50 is configured to press liquid from a flat mop pad 80 (see Figure 6).

  • the presser pad 51 can be configured to pivot relative to the pressure member 50 about a fifth pivot location 55.
  • the presser pad 51 can include a crossbar member 56 that extends through a hole (not shown) in the first extending portion 53 to allow the presser pad 51 to pivot relative to the first extending portion 53.
  • the presser pad 51 can include a gap 52 in its middle to accommodate connecting hardware on a mop (not shown).
  • the intermediate member 60 is connected to the foot pedal member 40 at a second pivot location 45 and is connected to the presser member 50 at a third pivot location 54.
  • the connections can be conventional connections that allow the components to pivot relative to one another.
  • the intermediate member 60 can be an member made of steel that extends in a substantially straight line and having ribbing to increase strength.
  • the wringer 10 can be constructed such that the second and third pivot locations 45, 54 are on the second side of the imaginary straight line 28 (see Figure 6).
  • the wringer 10 includes sets of two of each of the first extending portion 42, second extending portion 43, third extending portion 44, torsion spring 48, intermediate member 60, and first extending portion 53.
  • This configuration provides a preferred degree of robustness and stability.
  • These sets of members each could be connected by cross linking devices (not shown) to further enhance their robustness and stability.
  • the wringer 10 could, however, be configured with only one of each of those members.
  • the mop bucket 70 is configured to be retained in the bucket location 23 of the frame 20. As shown in Figures 3 and 4, the mop bucket preferable includes a wringer member 71 with a plurality of holes 72.
  • the wringer member 71 is angled downward from a rear wall 73 at an angle of approximately 60 degrees relative to vertical to provide additional clearance at the front of the mop bucket 70 (see Figure 4). If the wringer member 71 extended in only the horizontal direction, it would occupy additional space in the horizontal direction. By providing the downward angle, additional space is made available in the horizontal direction for inserting, removing, and scrubbing the mop pad 80 in the bucket 70.
  • the mop bucket can also include a scrub board 74 having a series of ribs 75. The scrub board 74 allows a user to scrub debris off of the mop pad 80 while rinsing the mop pad 80 in the liquid in the mop bucket 70.
  • the surface of the scrub board 74 angles downward from a front wall 76 at an angle of approximately 32 degrees relative to vertical.
  • the user can rub the mop pad 80 up and down along the ribs 75 (preferably while the mop pad is mounted on the mop pad support) to remove dirt and debris from the mop pad 80.
  • the ribs 75 facilitate the scrubbing. Some of the ribs 75 can be wider than others to serve as volume level indicators for the liquid in the mop bucket 70.
  • the mop bucket 70 can be, for example, made of plastic.
  • the wringer 10 of the present invention is advantageous because, for example, it can be configured to provide a clearance between the presser pad 51 and the mop bucket 70 (see Figure 5).
  • the torsion spring 48 returns the foot pedal member 40 to its upper position ( Figure 5), which raises the presser pad 51 above the rim of the bucket 70. It is important that the presser pad 51 clear the rim of the bucket 70 to allow easy insertion of the mop pad 80 and to allow easy removal of the bucket 70 from the frame 20 for emptying and cleaning.
  • the wringer 10 of the present invention is advantageous because it can be configured to provide a desired amount of wringing pressure on the mop pad 80 in response to a particular amount of actuation force by a user on the foot pedal member 40. It has been determined through experimentation that, with a configuration like the embodiment shown in the drawings, a pressure of approximately 2 lbs. per square inch from the presser pad 51 onto a typical mop pad 80 on the wringer member 71 is needed to remove a desired quantity of liquid. Beyond 2 lbs. per square inch of pressure, the amount of liquid removal is less significant.
  • a typical mop pad 80 has a plan area of about 125 square inches.
  • F MOP could be at least 175 lbs. or, more preferably, at least 200 lbs.
  • F PEDAL the force applied by the user to the foot pedal member 40
  • F PEDAL the force applied by the user to the foot pedal member 40
  • some users may be upwards of 140 lbs., preferably F PEDAL ⁇ 100 lbs.
  • F PEDAL ⁇ 84 lbs the force (F MO P) at the pressure pad 51 84 lbs.
  • the wringer 10 of the present invention can be configured to provide the desired force at the presser pad 51 in response to the available force on the foot pedal member 40.
  • movement of at least the second pivot location 45 toward the imaginary straight line 28 upon actuation of the foot pedal member 40 by a user causes an increase in force applied by the presser pad 51.
  • a wringer in accordance with the present invention thus can be configured to be foot operated, which relieves the stress and pain of having to wring out a mop bending over by hand. Additionally, the wringer can be configured to provide the desired force on the mop pad in response to a desired amount of force applied by the user's foot.
  • the scrub board in the mop bucket also provides the ability to remove dirt and debris that accumulates on the flat mop.
  • the wringer 10 of the present invention can be used with many flat mop pads and flat mop pad supports. Preferably, it is used with a flat mop pad disclosed in a patent application to be concurrently filed by Judy Cline entitled "Color Coded Mop Pads and Method of Color
  • the wringer 10 is used with the flat mop pad support disclosed in a patent application to be concurrently filed by the present inventor entitled "Mop Having Ergonomic Handle and Joint" (Serial No. ; Attorney Docket Number 086554-1179), the entire contents of which is hereby incorporated by reference.
