The present disclosure relates to a durable cleaning mop, the mop capable of wringing water and cleaning solution out of a saturated string-type, braided cord mop head.
Mops are an essential cleaning tool for many households and businesses. Over time, improvement of mops and related technologies has resulted in several categories of mops, each with specialized capabilities and intended uses. Generally, mop categories include flat-mops (including sponge, scrubbing pad, and disposable pad or “Swiffer” type mops), string-mops, and centripetal spin-mops. Cleaning with a mop can be achieved with either a wetted mop, or a dry mop. Within each category, specialized designs exist that are best suited to either wet or dry use. For fast daily maintenance cleaning, dry flat mops are often preferred. For periodic thorough cleaning, or for larger and/or wet and dirty jobs, a wet mop is required.
In order to use a wet mop, a source of liquid is required. Until recently, this meant that a bucket of water and/or a cleaning solution, or another vessel of water, such as a sink, would need to accompany a mop. Several varieties of mops now exist with a built-in liquid supply, and application means, typically a hand operated pump and sprayer. Less commonly, products exist with a separate backpack mounted fluid tank, and a means to deliver the liquid to the mop head fibers or flat pad. These are typically for commercial or institutional use.
String-mops have proven to be the preferred choice for wet mop applications, especially when large areas of flooring must be cleaned. There are two main types of mop heads utilized within the string mop category: looped and open ended mop designs. A looped mop head utilizes a continuous string, often several hundred feet in length. This string loops back and forth repetitively. Open ended mop heads use cut lengths of string, bundled and attached together. This results in cut ends of the strings contacting the floor, and typically faster absorption of the cleaning liquid solution.
Over time, string-mops have evolved from utilizing a conventional straight string into utilizing a more durable twisted string. Twisted strings are generally formed by coiling several strands together in the same direction, where the fibers within each of the strands must twist in the opposite direction as the corresponding strands. Stitch threads are generally used to keep the fibers twisted at a particular geometry. The result is a twisted string which hangs straight and resists kinking
String-mops inherently absorb large volumes of water, whether from the cleaning solution vessel or from the flooring surface that is being cleaned. This strength is balanced by a weakness: a high level of resistance to releasing the liquid, once absorbed. As a result, several wringing mechanisms have been conceived, and are commercially available today.
While string-mops continue to be popular, they have two critical flaws. First, wringing effectiveness is dictated by the user's strength, and willingness or capability to rotate the mop's handle grip, relative to the main handle, through several full revolutions. This is both time consuming, and fatiguing. Second, each end of a twisted string must be fused together to prevent unraveling. Thus a simple tear can cause the string to become untwisted, unraveled, and unusable.
Hence, a need exists for an improved mop with a wringing mechanism that provides for substantially quicker and physically easier use and a mop head with improved durability that provides the same or increased absorbent qualities as conventional mops.
The present disclosure relates to a durable cleaning mop capable of wringing water and cleaning solution out of a saturated string type mop head.
In accordance with certain aspects of the present disclosure, a mop includes a mop pole, a lower handle grip mounted around a lower portion of the mop pole and configured to move axially along the mop pole, an upper handle grip at least partially mounted around an upper portion of the mop pole and configured to move axially along the mop pole, and a rotational mechanism capable of imparting rotation into the mop pole in response to axial movement of the upper handle grip.
In accordance with certain aspects of the present disclosure, a mop head includes a collar and a braided cord comprised of a plurality of strands. The collar is positioned at a top end of the mop head and is capable of attaching around a lower portion of a lower handle grip of a mop pole. The braided cord is arranged around the collar and attached to itself such that the cord forms a plurality of apertures and a plurality of loops.
In accordance with certain aspects of the present disclosure, a collar for a mop head includes a body capable of securing a mop head to a mop pole. The collar body may include a post end and a loop end, where the loop end is configured to accept the post end. The collar is capable of attaching around a lower portion of a lower handle grip of a mop pole.

The present disclosure relates to a durable cleaning mop capable of wringing water and cleaning solution out of a saturated string type mop head. It provides an improved mop and mop head, of similar construction to the previously described string-mops.
The upper handle grip 102 is mounted around and configured to slide axially about an upper portion of the mop pole 101 and, in some examples, can be attached to an upper locking structure 107. Additionally, the upper handle grip 102 encloses an internal rotational mechanism (not shown) that can impart rotation into the mop pole 101 when the upper handle grip 102 moves axially along the mop pole 101.
The lower handle grip 103 is mounted around and configured to slide axially about a lower portion of the mop pole 101 and, in some examples, can be attached to a lower locking structure 108. Additionally, the lower handle grip 103 is removably attached to a top end of the mop head 104.
The mop head 104 can be any looped mop head, which can attach to the lower handle grip 103 and the mop pole 101. As shown in
It is also contemplated that the cleaning mop 100 can include a hook 105 secured to the top of the mop pole 101. The shape and size of the hook can vary in alternate examples to permit, inter alia, the cleaning mop 100 to hang on a wall hook.
The inserts 210 are securely attached to the inter walls of the upper hand grip 102. The rotational mechanism 200 is not limited to two inserts 210 as illustrated in
One end of the rotatable portion 212 is inserted in an upper end of the mop pole 101, and the other end of the rotatable portion 212 is inserted in a hollow core of the rotating element 211. With such a configuration, as the upper handle grip 102 is moved axially along the mop pole 101, the helical prongs 213 of the inserts 210 catch helical grooves 214 of the rotating element 211 and cause the rotating element 211 to rotate. In a gear-like fashion, teeth 215 of the rotating element 211 catch teeth 216 of the rotatable portion 212, thereby imparting rotation on the mop pole 101. The plug 209 is attached to an end of the rotating element 211 to serve as a damper, which may, among other things, absorb any force that may damage the rotational mechanism 200 or absorb any shock that may be felt by a user of the mop 100.
In some examples, the rotational mechanism 200 imparts rotation into the mop pole 101 only when the upper handle grip 102 moves axially in a downward direction and does not affect the mop pole 101 when the upper handle grip 102 moves axially in an upward direction. Likewise, in some examples, the rotational mechanism 200 imparts rotation into the mop pole 101 only when the upper handle grip 102 moves axially in an upward direction and does not affect the mop pole 101 when the upper handle grip 102 moves axially in a downward direction. Therefore, the mop allows for multiple strokes of the of the upper handle grip 102, each successively wringing the mop head fibers tighter.
While
In an embodiment of the present invention, the collar 521 may be a wire having its two ends connected to each other (for example, by looping the ends around each other, by welding, etc.) to form a loop. In such embodiment, the lower handle grip 103 may be fed through the loop formed by the collar 521 and the mop head 104. In other embodiments, as illustrated in
In some examples, as seen in
As shown, the post end 524 and the hook feature 526 are parts which can be “over-molded” or “insert molded” over the collar 521. Likewise, the loop end 523 of the collar 521 can be bent and “over-molded.” Thus, a portion of the wire is left unmolded to retain an aperture which can accept the post end 524 of the collar 521.
In some examples, the loop end 523 is a C-Clip (not shown) which is equipped with a post and loop type clasp. The C-Clip can allow slight overlap of the mop head fibers, preventing the formation of a gap down the length of the mop head 104.
The collar 521 may be made of a variety of materials including galvanized steel wire and silicone coated annealed wire.
Referring back to
Similarly, the cleaning mop 100 can be in the wringing mode by stretching the loops of the mop head 104 using the lower handle grip 103 and then rotating the bottom of the mop head using the upper handle grip 102.
The method of wringing the mop is generally a two-handed operation. However, no rotation of the user's hands, relative to each other, is required to achieve effective wringing of the mop. In some examples, the method of wringing the mop involves the user, with a first hand, lifting the lower handle grip 103, stretching the loops of the mop head 104, and supporting the mass of the mop. While the lower handle grip 103 is still being held with the first hand, the upper handle grip 102 is moved upward along the mop pole 101 and then downward along the mop pole 101 with a second hand. Upon downward motion of the upper handle grip 102, the mop pole 101 rotates, and in turn rotates the bottom of the mop head 104 relative to the top of the mop head 104. This twisting of the mop head 104 results in compression of the loops, and release of the liquid absorbed in the mop head 104.

Upon upward motion of the upper handle grip 102, the mop pole 101 rotates, and in turn rotates the bottom of the mop head 104 relative to the top of the mop head 104. This twisting of the mop head 104 results in compression of the loops, and release of the liquid absorbed in the mop head 104.
The number of loops 928 within the mop head 104 may vary between examples. For instance, the mop head 104 can include less than thirty loops 928 or over seventy loops 928. However, generally a mop head 104 includes between thirty and seventy loops 24. For example, the mop head 104 can include about fifty loops 928.
Likewise, the length of the mop head 104 can vary between examples. In some examples, the length of the mop head is about thirty-five centimeters.
In some examples, as shown in
The loop strap 929 can include a number of materials including, but not limited to, tape, fabric, hook and loop fasteners, cable ties, zip ties, rubber bands, plastic and other similar materials capable of binding the plurality of loops 928. Generally, a lock ring, such as lock rings 318 and 421, can be placed on top of the loop strap 929. However, in some examples, a lock ring may be used directly in place of a loop strap 929.
The braided cord 927 includes a body which is substantially similar to a “Chinese finger trap”—the diameter of the braided cord 927 narrows as its two ends are pulled away from each other. Pulling the entire braid lengthens and narrows it. The length is gained by reducing the angle between the warp and weft threads at their crossing points, but this reduces the radial distance between opposing sides and hence the overall circumference. The more one pulls, the more the circumference shrinks and the braid tightens. Hence, the braided cord 927 can absorb liquid in a low-tension state where the circumference is exploited and can expel an absorbed liquid when the braided cord 927 is stretched. Similarly, the braided cord 927 can also be wrung out if twisted, compressed, or squeezed.
As noted above, at least one disadvantage of a twisted string is its propensity to unravel. In contrast, a braided cord 927 can withstand much more abuse than a twisted string and its braided body continues to provide support even with a spliced strand or end. For example, if a single strand of a twisted string were to break, none of remaining intact strands would provide support to that broken strand. Thus, the broken strand in a twisted string could potentially unravel throughout the entire length of the string. In contrast, if a single strand of the braided cord were to tear, the intertwining structure of the braid can resist the unraveling force of the single broken strand. Likewise, if the entire cord is spliced, a twisted string would unravel completely, whereas a braided cord might unravel near the end but would retain its braided structure long enough for a quick repair.
Moreover, the structural integrity of a braided cord is integral to its braided design, unlike a twisted string, whose structural integrity relies on a stitch thread that runs vertically along the mop head. A broken stitch thread results in an untwisted string. Also, certain mop heads with twisted strings include a horizontal band stitched around the twisted strings to reinforce the twists and prevent tangling. The braided cord, on the other hand, is less likely to become tangled.
The number of strands 1233 within the braided cord 927 can affect at least the durability and flexibility of cord 927. Therefore, the number of strands 1233 within the braided cord 927 can vary in alternate examples, depending on desired characteristics. For instance, a braided cord 927 with fewer strands 1233 will generally be more flexible (and perhaps easier to maneuver around the hard-to-reach areas on the floor), while a braided cord 927 with more strands 1233 will generally provide for a more durable braid.
Referring to
The mop head material may vary in alternate examples, but generally the mop head includes material that will not scratch any surface and is highly absorbent. Additionally, the material itself is generally quite durable. For instance, in some examples, the mop head material may endure the toughest washing machine cycles. The material can include but is not limited to polyester, polyamide, cotton, microfiber, viscose, nylon, or synthetic fibers. For example, the mop material may include a unique absorbent “chenille” synthetic fiber. This fiber absorbs a large volume of liquid, but also readily releases the liquid when compressed. These properties typically exist exclusively. In some examples, one of the plurality of strands 1233 forming the braided cord 927 may include a different material than other strands within the plurality of strands 1233.
The size of the core 1334 may vary between examples for many reasons including, but not limited to, the number of strands 1233 in the braided cord 927, the size of the strands 1233, the braid tightness, and the amount of liquid absorbed by the strands 1233. For instance, if the braided cord 927 is pulled, the core 1334 may be extremely small or substantially non-existent. Likewise, if the braided cord 927 has absorbed liquid, the strands 1233 may expand such that the core 1334 may be extremely small or substantially non-existent.
In some examples, the mop head 104 is machine washable. As partly illustrated in
On the other hand, the mop head 104 may be completely replaced with a new mop head or portions of the mop head may be replaced. For instance, the collar 521 may be replaced with a new collar 521, the continuous braided cord 927 may be replaced, or the entire mop head 104 may be replaced.
