Description
FIELD OF THE INVENTION

The present disclosure relates to a bucketless handle coupled to a cleaning element, and more specifically to a bucketless handle coupled to a cleaning element that may be used independently or with a user-wearable backpack.


BACKGROUND OF THE INVENTION

Advancements continue to be made in cleaning devices adapted to dispense fluid onto one or more surfaces in relation to wiping, scrubbing, mopping, finishing, or other operations performed by the cleaning devices. Examples of such cleaning devices include mops, dusters, finishers, and similar tools. Such cleaning devices and finish application tools can incorporate an attached container or a remote reservoir design for holding a liquid such as water, disinfectant, finishers, and/or other solution.


In many cases, the cleaning devices are expensive and are configured only for use with a single accessory. Accordingly, such devices can require a distributor to stock one particular item for use with the cleaning device, such as an exclusive floor finish formula and corresponding container. These devices are typically not utilized for any other activity and often become an underutilized capital investment once a cleaning or refinishing task is complete. Likewise, the cleaning devices are typically not appropriate for a variety of cleaning tasks and are only useful under limited circumstances. While such cleaning devices are often suitable for their intended uses, they are often inconvenient for a user. Further advancements in this technology are always welcome in the art.


It is desirable to have a cleaning device that is capable of cleaning and treating a variety of surfaces using various solutions, interchangeable between an independent cleaning device and a cleaning device connected to a remote reservoir, and convenient to use.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS OF THE INVENTION

The following detailed description and appended drawings describe and illustrate various exemplary embodiments of the invention. The description and drawings serve to enable one skilled in the art to make and use the invention, and are not intended to limit the present disclosure, application, or uses.



FIG. 1 illustrates a cleaning device 10 according to one embodiment of the disclosure. The cleaning device 10 includes a bucketless handle assembly 12 coupled to a removable cleaning element 14 and removeably attached to a user-wearable backpack 16 and belt 18. The cleaning device 10 may be used with interchangeable cleaning elements 14 and various types and volumes of cleaning solutions. Alternatively, as will be further described herein below, the cleaning element 14 and the bucketless handle assembly 12 may be used independently from the backpack 16 and belt 18.


The bucketless handle assembly 12, as more clearly shown in FIGS. 2-8, includes a handle portion 20 and a frame 22. The handle portion 20 is typically rigid, elongate, and substantially cylindrical and may be made from metal, plastic, or any other light weight material that may be easily gripped by the user. The handle portion 20 has a first end and a second end. An actuator 24 is disposed at the first end of the handle portion 20 and the frame 22 is removeably connected to the second end of the handle portion 20. A dispensing container 26 is disposed in a container support 28 that may be permanently or removeably connected to the handle portion 20 intermediate the first end and the second end. The container support 28 also includes a dispensing element 30 in fluid communication with the dispensing container 26 for dispensing the solution in front of, behind, or onto the cleaning element 14 of the cleaning device 10 when in use. A hook 32 or other device used for hanging the handle assembly 12 may also be attached to the handle portion 20 intermediate the first end and the second end. The hook 32 and the container support 28 may be made from any light weight and durable material such as plastic, for example. At least a portion of the dispensing container 26 and the dispensing element 30 are typically made from a translucent material such as plastic, for example, that is capable of containing the liquid or gel solution.


The frame 22 includes a coupling device 34 and a receiving member 36. The coupling device 34 is typically cylindrical and hollow. The second end of the handle portion 20 may be inserted into a first end of the coupling device 34. In certain embodiments of the disclosure, the second end of the handle portion 20 and a first end of the coupling device 34 may include openings 38 that have a corresponding shape and size as more clearly shown in FIGS. 6A and 6B. Upon alignment of the openings 38, a securing element 40 may be positioned by the user to extend through each of the openings 38 in order to secure the handle portion 20 to the coupling device 34. Other means for removeably connecting the frame 22 and the handle portion 20 may be used, as desired. For example, the coupling device 34 may include male protrusions 42 for insertion into the openings 38 included on the handle portion 20, or vice versa. The frame 22 may be interchangeable with additional frames 22 having varying shapes, sizes, and cleaning purposes. Accordingly, the user can use one handle portion 20 with many different frames 22 to perform numerous cleaning jobs.


The receiving member 36 is attached to the frame 22 adjacent a second end of the coupling device 34. The receiving member 36 is typically thin and planar and may be made from any lightweight and resilient material such as plastic, for example. The receiving member 36 may be any shape, as desired. The cleaning element 14 is removeably connected to the receiving member 36 of the frame 22 using any means such as a friction fit, hook and loop fastener, elastic, or any other mechanical fastener. A variety of cleaning elements 14 may be employed, such as those adapted for dusting, damp mopping, deep cleaning, disposable heads, floor finish applications, staining applications, and use on concrete, for example.


The dispensing container 26 is typically made from a material such as plastic, for example, and includes a first removable cap 27 at a first end of the dispensing container 26 and second removable cap 29 at a second end of the dispensing container 26 allowing for easy rinsing and cleaning of the dispensing container 26 when both caps 27, 29 are removed. The first end of the dispensing container 26 may have a larger diameter to allow for easy pouring of the solution contents into and out of the dispensing container 26. The second end of the dispensing container 26 including the cap 29 may be directly connected to or in fluid communication with the dispensing element 30. The dispensing container 26 may be easily removed and replaced in the container support 28 by alternative dispensing containers 26 allowing different solutions such as cleaner, disinfectant, finisher, etc. to be quickly and easily interchanged within one cleaning device 10. Accordingly, the user may remove one dispensing container 26 and replace it with another in order to perform various cleaning tasks. In certain embodiments, the dispensing container 26 may only be able to dispense the solution when properly positioned in the container support 28.


At least one of the removable caps 27, 29 may have a tethered portion including a loop 31 or similar feature that allows the dispensing container 26 to be suspended from a hook located on a wall, independent docking station, or another location that is independent of the cleaning device 10 when the dispensing container 26 is not in use. This allows for easy storage and organization of many dispensing containers 26 containing various cleaning solutions. The dispensing container 26 may be transparent or translucent or have a transparent or translucent strip, include one or more labels, and can also include graduated indicia that identify the fill level of the contents of the dispensing container 26. The dispensing container 26 may have a groove in the portion adjacent the handle portion 20 in order to stabilize and secure the dispensing container 26 against the handle portion 20.


As clearly shown in FIG. 5, the actuator 24 includes a push-button 44 disposed on the first end of the handle portion 20 that actuates a system 46 for releasing the solution housed in the dispensing container 26. The system 46, as illustrated in FIG. 8, utilizes a gravity feed and includes a valve 58 that prevents the contents of the dispensing container 26 from exiting through the dispensing element 30 until a linear actuation thereof. The user can release the contents of the dispensing container 26 by depressing the push-button 44 on the handle portion 20 which actuates a rod 60 similar to that found in a ball point pen. The rod 60 urges the valve 58 into a chamber 55 away from an opening 56. By pressing the push-button 44 located on the handle portion 20, the system 46 moves to a lock-on position and the solution can exit the dispensing container 26 and travel through the opening 56 in the handle portion 20 and out the dispensing element 30. The solution can continue to exit the dispensing container 26 until the push-button 44 is pressed again, thereby closing the valve 58 and preventing the solution from flowing through the opening 56 and exiting the dispensing container 26. The valve 58 may be a cartridge valve that is flooded with the solution from the dispensing container 26 at an inlet in certain embodiments of the disclosure.


The system 46 for releasing the solution in the dispensing container 26 can include a sprayer option wherein when the system 46 is locked on, the solution is pumped to the frame 22 or the dispensing element 30. In some embodiments, the dispensing container 26 can be pressurized where a propellant such as pressurized air forces liquid out of the dispensing container 26 when the push-button 44 on the handle portion 20 actuates the system 46. Other embodiments may include a pre-packaged, single use dispensing container 26 for use with the cleaning device 10.


The handle portion 20 may be connected to the user-wearable backpack 16 in certain embodiments. The backpack 16, as shown in FIGS. 1, 9, 10, and 16, includes a reservoir or bladder 48 disposed in the backpack that may be filled and refilled from any 1 gallon bottle, 5 gallon pail, 55 gallon drum, or other container to hold any type of floor disinfectant, cleaner, or finish (see FIG. 11). The bladder 48 may be removeably connected to the dispensing container 26 using a conduit or tube 50 in order to supply the solution to the dispensing container 26 (see FIG. 12). The solution then passes through the dispensing container 26 and out the dispensing element 30, as described hereinabove. Alternatively, the bladder 48 may be coupled to the handle portion 20 or a portion thereof directly in place of the dispensing container 26. An adapter element 52 may be disposed at one end of the dispensing container 26 or at one end of the tube 50 allowing the actuator 24 to work even when the solution originates from the bladder 48, rather than the dispensing container 26. Specifically, the tube 50 may extend from the bladder 48 and through the dispensing container 26, bypassing the solution contained in the dispensing container 26, or the dispensing container 26 can be eliminated. The tube 50 connects to the adapter 52 such that when the valve 58 is opened by activating the push-button 44, solution from the bladder 48 continuously exits the bladder 48 as it would from the dispensing container 26. In certain embodiments, as shown in FIG. 8, the adaptor 52 may be an insert removeably connected to the tube 50 that is positioned and secured between the dispensing container 26 and the cap 29 when the cap 29 is threaded onto the dispensing container 26. The adaptor 52 may also be integrally formed with the cap 29 in certain embodiments of the disclosure.


The backpack 16 may include various additional features. For example, an adjustable sternum strap 64 may be connected to one or more straps on the backpack 16 (see FIGS. 9 and 16). Additionally, one or more pads 68 and/or vents 70 may be included on a front portion of the backpack 16. As shown in FIG. 9, a rear portion of the backpack may include one or more pockets 72 including warning or caution labels on an outer surface of the pockets and capable of storing additional warning or caution signage, for example. The caution labels on the rear portion of the back pack 16 may be important when the user is walking backwards while mopping a floor. Additionally, a viewing window 62 may be included on the rear portion of the backpack allowing a user to see if the bladder 48 is full of solution or empty. Compartments 54 may also be provided for holding Material Safety Data Sheet (MSDS) and/or Safety Data Sheet (SDS) information and additional collapsible signage (e.g., freestanding “wet floor” or “caution” signs). Compartments 54 for holding replacement cleaning elements 14 for attaching to the frame 22 or other cleaning pads or materials may also be included on the backpack 16 (see FIG. 14). One of more of the compartments 54 may include a waterproof, removeable compartment liner 66 including one of more dividing elements so that both unused and used cleaning elements may be stored separately (see FIG. 15). A bag liner may also be incorporated into the backpack 16 where the bladder 48 is disposed. The backpack 16 may be configured to hold and/or dispense other accessories such as protective eyewear, shoe covers, disposable gloves, hand sanitizer, black pads, masking tape, a putty knife, and a two-way radio, for example. Reflective material and/or highly visible colors may also be incorporated into the backpack 16. Additional dispensing containers 26 may also be held by the backpack 16.


The belt 18, as shown in FIG. 13, is typically removeably connected to the backpack 16 and may be used to further secure and stabilize the backpack 16 on the user. A buckle or tie mechanism may be included on the belt 18 to enclose the belt 18 around a waist of the user. The belt 18 may also include warning or descriptive signage held in compartments 54 with windows or attached to the belt 18. Compartments 54 for holding replacement cleaning elements 14 for attaching to the frame 22 or other cleaning pads or materials may also be included. A bag liner may be incorporated into the belt 18 to hold used cleaning elements 14. Similar to the backpack 16, the belt 18 may be configured to hold and/or dispense other accessories such as protective eyewear, shoe covers, disposable gloves, hand sanitizer, black pads, masking tape, a putty knife, and a two-way radio, for example. Reflective material and/or highly visible colors may also be incorporated into the belt 18.


In use, the user will evaluate the task to be performed. For illustrative purposes, the user may determine that a small floor surface needs to be disinfected. Accordingly, the user will select a disinfectant solution and an appropriate cleaning element 14. The user will position the cleaning element 14 on the frame 22 and pour the appropriate solution into the dispensing container 26. Alternatively, the user may simply select a dispensing container 26 already containing the appropriate solution and position the dispensing container 26 in the container support 28. To actuate the handle assembly 12, the user will depress the push-button 44 thereby activating the system 46, opening the valve 58, and permitting the solution to flow from the dispensing container 26, through the opening 56 in the handle portion 20, and out of the dispensing element 30. Once the user determines that an adequate amount of solution has been released from the dispensing container 26, the user presses the push-button 44 again to disengage the system 46 and close the valve 58. The user may repeat activation of the system 46 as needed. Alternate cleaning elements 14 and/or solutions may be selected for various tasks. The handle assembly 12 and the dispensing container 26 may be easily stored using the hook 32 and the loop 31, respectively.


It is possible that the user may determine that a large or remote floor surface needs to be disinfected. Accordingly, the user will select a disinfectant solution and an appropriate cleaning element 14. The user will position the cleaning element 14 on the frame 22 and pour the appropriate solution into the bladder 48. The user may then connect the tube 50 to both the bladder 48 and the adaptor 52 in order to create a fluid path from the bladder 48 to the handle assembly 12 for the solution. To actuate the cleaning device 10, the user will depress the push-button 44 to activate the system 46 and open the valve 58, permitting the solution to flow from the bladder 48, through the opening 56 in the handle portion 20, and out the dispensing element 30. Once the user determines that an adequate amount of solution has been released, the user presses the push-button 44 again to disengage the system 46. The user may repeat activation of the system 46 as needed. Alternate cleaning elements 14 and/or solutions may be selected for various tasks. Additionally, the user may access new cleaning elements 14 and other required items relating to safety and performance of the tasks, and store items such as used cleaning elements 14 on the backpack 16 and/or the belt 18. The handle assembly 12 and the backpack 16 may be easily stored using the hook 32 and a loop included on the backpack, respectively.


The cleaning device 10 may be used for large and small projects alike as a result of to the interchangeability between the stand-alone handle assembly 12 and the combined handle assembly 12 and backpack 16 cleaning device 10. The lightweight and simple handle assembly 12 makes cleaning in small, difficult to reach places easy and efficient. The agile maneuverability, portability, and large reservoir capacity of the cleaning device 10 including the backpack 16 allows the cleaning device 10 to be employed by floor care professionals in schools, acute care, long term care, health & fitness, food service, dental, big box retail, hospitality, entertainment, salon, office, and convenience store environments, among others. Additionally, the interchangeability between the various dispensing containers 26, frames 22, and cleaning elements 14 allows the cleaning device 10 to be used for a variety of tasks such as cleaning, mopping, and applying floor finish, for example. The user benefits from a better, easier to use cleaning device 10, a more efficient cleaning device 10, the flexibility to utilize the floor solution of choice, and the opportunity to use the cleaning device 10 in any environment for a project of any size.
