Abstract
Disclosed is a brush for cleaning toilet bowls and the like. The brush has a permanent handle and can be used with a replaceable/disposable brush head that is flushable after use. The brush is a stack of sheets of water-dissolvable material. The sheets are compressed to both bind them together into a stack. There is a longitudinal slit in the rear of the brush head to create left and right rear attachment tabs. A wand provides a remote system for clamping and unclamping the brush head. The wand has a jaw whose mouth has two wedge shaped teeth that are offset from each other to clamp the corresponding tabs while driving the tabs in opposite directions in the jaw.
Claims14
A cleaning implement, comprising:
- a handle having a clamping jaw;
- and
- a brush head suitable to be held in the jaw;
- wherein the brush head has a slit extending from a rearward end of the brush head part way forward along the brush head so as to define a left rear and a right rear portion of the brush head such that at least one of the left and right rear portions can be pivoted upward relative to a central portion of the brush head while the other of said left and right rear portions can be pivoted downward relative to the central portion;
- wherein the jaw has an upper jaw part and a lower jaw part, the upper jaw part having a downwardly projecting tooth, and the lower jaw part having a upwardly projecting tooth, and the downwardly projecting tooth and the upwardly projecting tooth are offset relative to each other in a sideways direction;
- and
- wherein the brush head can be positioned relative to the jaw such that one jaw tooth contacts the left rear portion and the other jaw tooth contacts the right rear portion, with the jaw teeth pivoting the left rear portion of the brush head and right rear portion of the brush head in opposite directions in the jaw.
A wand for holding a brush head, the brush head being of the type having a slit extending from a rearward end of the brush head part way forward along the brush head so as to define a left rear and a right rear portion of the brush head such that at least one of the left and right rear portions can be pivoted upward relative to a central portion of the brush head while the other of said left and right rear portions can be pivoted downward relative to the central portion, the wand comprising:
- a handle having an internal axial cavity, a lower opening communicating with the cavity, and an activator opening;
- and
- an actuator having a projection extending through the activator opening, a connecting rod linked to the projection which is mounted in the handle cavity, and a jaw linked to the rod which extends out the handle lower opening;
- wherein the jaw has an upper jaw part and a lower jaw part, the upper jaw part having a downwardly projecting tooth, and the lower jaw part having a upwardly projecting tooth;
- wherein the downwardly projecting tooth and the upwardly projecting tooth are offset relative to each other in a sideways direction;
- and
- wherein the wand is constructed and arranged such that a first movement of the projection will move the jaw to a first position suitable to release the a brush head if the brush head has been inserted in the jaw, and a second movement of the projection will move the jaw to a second position suitable to clamp the a brush head if the a brush head has been inserted in the jaw, and such that the jaw teeth can pivot the left rear portion and right rear portion in opposite directions in the jaw when the second movement occurs if the brush head has been inserted in the jaw.
A brush head suitable to be held by a cleaning device, wherein the brush head comprises:
- a plurality of layers of a water-degradable material positioned on top of each other in the form of a stack of such layers;
- wherein the brush head has a slit extending from a rearward end of the brush head part way forward along the brush head so as to define a left rear and a right rear portion of the brush head such that at least one of the left and right rear portions can be pivoted upward relative to a central portion of the brush head while the other of said left and right rear portions can be pivoted downward relative to the central portion;
- and
- wherein the brush has a series of undulations on both its top and bottom surfaces.
