Charging System

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001]This application claims priority to U.S. Provisional Ser. No. 63/664,709 , entitled “Charging System” and filed Jun. 26, 2024, which is incorporated by reference herein in its entirety.

BACKGROUND

[0002]Traditional mop charging, or pre-saturation, systems have predominantly relied on cart-based designs incorporating substantial stainless steel structural frames. These systems, while functional, tend to be large, cumbersome, and not easily adaptable to varying cleaning environments, including smaller enclosed spaces such as hood-cleaning environments or benchtop work surfaces.

[0003]Existing systems require significant liquid volumes to operate effectively, generate excess fluid waste, and are not well-suited for environments requiring compact, portable, and rapidly deployable cleaning solutions. A need therefore exists for a charging system that is lightweight, modular, capable of recycling excess cleaning fluid, and adaptable for use with or without a cart in a variety of hood-cleaning, benchtop, and commercial cleaning environments.

SUMMARY OF THE INVENTION

[0004]The present invention provides a charging system for mops that enhances cleaning efficiency, reduces liquid waste, and offers modularity for use across diverse cleaning environments.

[0005]In one aspect, the invention provides a charging system comprising a saturation tray defining a liquid reservoir, a liquid removal and reclamation ledge integrated with the saturation tray and configured to channel excess liquid from mops back into the liquid reservoir, and a support structure configured to receive and support the saturation tray. The saturation tray is removably received by the support structure.

[0006]In another aspect, the support structure is a rolling bucket having an open top configured to receive the saturation tray such that the tray is removable without tools.

[0007]In another aspect, the support structure is a freestanding frame having a plurality of legs, the frame being configurable in a benchtop height configuration or a floor-stand height configuration.

[0008]In another aspect, the saturation tray is a single-piece molded polymeric body defining the liquid reservoir and having the reclamation ledge coupled to the tray body.

[0009]In another aspect, the tray is available in multiple widths to accommodate mop heads of varying sizes, including mop heads up to approximately 18 inches (45 cm) in width.

[0010]In another aspect, the system is configured for pre-saturation of up to four mops in less than two minutes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024]The following description sets forth specific embodiments of the invention. It will be apparent to those skilled in the art that variations and modifications may be made without departing from the scope of the invention. The following embodiments are illustrative and not limiting.

I. Overview

[0025]Referring generally to FIGS. 1-12, the charging system 10 of the present invention comprises a saturation tray 100 and a support structure 200. The saturation tray 100 defines a liquid reservoir 110 and incorporates an integrated liquid removal and reclamation ledge 120. The support structure 200 is configured to receive and support the saturation tray 100 in an operative position, with the saturation tray 100 being removable from the support structure 200 without tools.

II. Saturation Tray

[0026]As shown in FIGS. 1-3 and 7-12, the saturation tray 100 is a single-piece molded polymeric body defining the liquid reservoir 110 configured to hold cleaning or disinfectant solution. In a preferred embodiment, the reservoir 110 has a capacity of up to approximately 3 liters and includes an integrated fluid level indicator line 116 to facilitate rapid approximation of remaining fluid volume. The tray 100 is configured to operate with as little as approximately 1 liter of fluid.

[0027]The reclamation ledge 120 is coupled to the tray body and includes a liquid-expressing surface, as shown in FIGS. 9-12. In use, a mop head is pressed against the liquid-expressing surface of the reclamation ledge 120 so that excess liquid is expressed from the mop head and channeled back into the liquid reservoir 110 for reuse in saturating subsequent mops. This fluid recycling capability reduces consumption of cleaning and disinfectant solutions.

[0028]The saturation tray 100 is constructed of lightweight, durable polymeric material and in a preferred embodiment weighs less than approximately 5 pounds (2.5 kg) when empty and less than approximately 15 pounds (7.5 kg) when loaded with liquid and mops. The tray 100 is autoclavable, facilitating use in environments requiring high-level hygiene protocols.

[0029]The saturation tray 100 is available in multiple widths. In one embodiment, a hood-cleaning tray has a width of approximately 10.5 inches (26 cm). In another embodiment, a room-cleaning tray has a width of approximately 18 inches (45 cm), configured to accommodate mop heads of approximately 14 inches (35 cm), 16 inches (40 cm), and up to 18 inches (45 cm) in width.

[0030]The tray 100 is optionally provided in multiple colors to facilitate an integrated color-coded sanitary maintenance system distinguishing between different cleaning zones or fluid types.

III. Support Structure-Rolling Bucket Configuration

[0031]As shown in FIGS. 1-3, 7, and 8, in one embodiment the support structure 200 is a rolling bucket 210 having an open upper end sized and configured to receive the saturation tray 100. The rolling bucket 210 is equipped with a caster wheel assembly 212 to facilitate transport. The saturation tray 100 is removably seated within the rolling bucket 210 such that it may be lifted out and removed without tools.

[0032]In a modular configuration shown in FIG. 3, two rolling buckets 210 may be joined side-by-side using a BucketBinder frame to form a dual-bucket system accommodating two saturation trays 100 simultaneously. The rolling bucket 210 may be paired with a bucket-based mop removal tool that facilitates collection of used mops into a waste bag without direct handling.

IV. Support Structure-Freestanding Frame Configuration

[0033]As shown in FIGS. 4-6, in another embodiment the support structure 200 is a freestanding frame 220 having a plurality of legs 222 and configured to support the saturation tray 100 at a predetermined height. The freestanding frame 220 is provided in at least two height configurations: a benchtop configuration having legs of a height suitable for placement on a work surface or within a hood-cleaning environment, as shown in FIG. 5; and a floor-stand configuration having extended legs suitable for use at floor level by a standing operator, as shown in FIGS. 4 and 6.

[0034]In the floor-stand configuration of FIG. 4, the freestanding frame 220 includes an extended vertical handle 224 and a caster wheel assembly 212 to facilitate repositioning.

V. Operation

[0035]In a pre-saturation mode, cleaning or disinfectant solution is introduced into the liquid reservoir 110 of the saturation tray 100. Up to four mop heads are then placed into the reservoir 110 simultaneously, allowing the mop heads to absorb the solution. Upon removal, each mop head is pressed against the reclamation ledge 120 to express excess liquid, which is channeled back into the reservoir 110 and reused to saturate subsequent mops. The system 10 is configured to pre-saturate up to four mops in less than two minutes.

[0036]The saturation tray 100 may also be used in a traditional dip-wring-mop mode in which a single mop head is repeatedly immersed in and wrung out from the reservoir 110.

Abstract

[0037]A charging system for mops comprises a single-piece saturation tray defining a liquid reservoir and having an integrated liquid removal and reclamation ledge configured to channel excess liquid expressed from mop heads back into the reservoir for reuse. The saturation tray is removably supported by a support structure, which may be a rolling bucket or a freestanding frame configurable in benchtop or floor-stand height configurations. The saturation tray is formed of lightweight, durable, autoclavable polymeric material and is available in multiple widths to accommodate mop heads of varying sizes. The system is configured to pre-saturate multiple mops simultaneously and to reclaim excess cleaning or disinfectant solution to reduce waste. Optional color-coded tray variants facilitate integrated sanitary zone maintenance.
