Description
BACKGROUND
1. Field of the Invention

The present application relates generally to handheld cleaning devices, and more particularly to an assembly for dispensing moistened towelettes and a handle device for grasping and using the towelettes.


2. Description of Related Art

A concern for a large number of individuals is cleanliness of surfaces in homes and businesses that are frequented. Direct hand contact with unsanitary or unclean surfaces as well as cleaning chemicals used to clean the surfaces is undesirable. In one instance, a common area of concern is the bathroom, and in particular the toilet seat. Many methods and devices have been developed to ensure the proper cleanliness of the toilet. For example, a cleaning compound and fluids may be sprayed onto a surface from a spray bottle to clean or sanitize the surface. Upon application to the surface, a user often wipes the dirty surface with a rag, sponge, tissue, or other similar cleaning device. In this instance, the cleaning device requires user's hand to be in close proximity to the surface, often in direct contact with the cleaning surface and/or the cleaning tissue. The tissue then becomes quickly saturated, typically contacting with the user's hand, after which the device or tissue must be discarded, cleaned, or laundered. Although, some devices do protect the user from holding the cleaning tissue directly by hand during the cleaning, after the cleaning it still requires the user to grab the tissue by hand to discard it. After such use, a user may be required to wash his/her hands, which is inconvenient and inefficient.


It is understood that this method of cleaning a surface has multiple limitations and disadvantages. For instance, to perform the cleaning, the user's hand is in direct contact with the cleaning tissue prior to cleaning, during, or after it once the cleaning tissue needs to be discarded or cleaned. Hands are susceptible to contacting the dirty surface and the saturated areas of the cleaning tissue itself causing many users psychological distress and possible irritation.


As a result, some users aim to avoid such close contact with cleaning devices or surfaces, especially toilet seats, while many others completely avoid use of any publicly accessible toilets due to unsanitary conditions, as well as unavailability of effective cleaning devices. Additionally, many individuals have allergies or other harmful reactions and irritations from various cleaning products that may make contact with the cleaning compound hazardous. Others don't want to touch the cleaning tissue because of the odor emitted by the cleaning compound (i.e. alcohol smell). Furthermore, it can be difficult to estimate the amount of cleaning compound and cleaning device necessary to avoid contact with the cleaning compound yet assure a thorough cleaning.


These disadvantages are only amplified by the thought of unsanitary surfaces in commercial establishments: public toilets, handles, tables, hospitals and so forth. For example, in hospitals there may exist any number of viruses and bacteria, or even biological substances that need to be cleaned up from a surface (i.e. blood). It is undesirable for a user to come into contact with any of these. Cleaning becomes even more complicated since many cleaning devices are stored apart from the cleaning tissue, forcing user to travel to the tissue storage container each time a tissue refill is needed, increasing chances of contamination and contact with tissues, dirt, and cleaning chemicals.


Although strides have been made to provide better cleaning devices and techniques, shortcomings remain. An improved cleaning device that separates the user from direct contact with the surface, cleaning compound, and cleaning tissue while providing a ready supply of saturated cleaning tissue for further use is needed.


SUMMARY OF THE INVENTION

It is an object of the present application to provide a cleaning assembly that includes a handle assembly configured to grasp a moistened tissue. A drum is included within a dispensing unit and configured to store the tissue. The dispensing unit selectively releases the tissue from the drum as an actuating assembly operates a lever between a first position and a second position. The drum is seated within the dispensing unit in communication with the actuating assembly. The cleaning assembly is designed to permit a user the ability to dispense a moistened tissue, grasp a moistened tissue, and clean with a moistened tissue without any contact with the moistened tissue or the selected cleaning surface.


It is a further object that the cleaning assembly engage with the drum in a manner that prevents the drying out of the moistened tissue. The cleaning assembly has a housing with a platform that seals around an opening of the drum. Also included is a moving platform that selectively seals beneath the housing platform. The moving platform disengages from the housing platform upon releasing of the moistened tissue.


Another object of the present application is to provide an actuating assembly that operates to disengage the moving platform from the housing platform prior to initiation of the rollers beginning the withdrawal of the moistened tissue. This prevents the moistened tissue from tearing. Movement of the lever arm in the actuating assembly first lowers the moving platform and then subsequently initiates the rollers as it moves from a first position to a second position.


The drum is configured to be interchangeable and optionally refillable with tissue.


The handle includes a jaw that opens and closes via an input from a user. The jaw is designed to grasp the moistened tissue when dispensed from the dispensing unit. With the handle, the user is able to locate the tissue on a desired surface and scrub the surface by pressing a pad of the handle against the tissue on the surface. The hands of the user never have to contact the tissue at any time.


Another object of the present application is to provide a tissue dispensing unit for a wall that contains tissue. The unit includes a drum configured to store the tissue. The drum has an opening for passage of the tissue outside of the drum. The assembly further includes a housing configured to store the drum on a housing platform, the housing platform has a slot for the passage of the tissue external to the drum and includes a seal around the slot. The seal is configured to seal about the opening of the drum. Additionally, the unit includes an actuating assembly with a lever for initiating the dispensing of the tissue external to the housing.


The unit includes a moving platform configured to selectively seal against the housing platform and the slot. The lever initiates movement of the moving platform. Likewise, the actuating assembly includes a plurality of rollers configured to apply a force to the tissue so as to dispense it from the drum and externally to the housing. The plurality of rollers operating only after the moving platform disengages from the housing platform and slot.


The tissue dispensing unit may be mounted away from a wall such as on a stand to allow it freedom to sit in any location, or be set on a counter or elevated surface.


Ultimately the invention may take many embodiments. In these ways, the present invention overcomes the disadvantages inherent in the prior art. The more important features have thus been outlined in order that the more detailed description that follows may be better understood and to ensure that the present contribution to the art is appreciated.

The embodiments and method of the present application is illustrated in the associated drawings. The cleaning assembly includes a handle assembly configured to grasp a moistened tissue. A drum is included within a dispensing unit to store the tissue. The dispensing unit selectively releases the tissue from the drum as an actuating assembly operates a lever between a first position and a second position. The drum is seated within the dispensing unit in communication with the actuating assembly in a manner such that the tissues are sealed and prevented from drying out. Additional features and functions are illustrated and discussed below.


Referring now to the Figures wherein like reference characters identify corresponding or similar elements in form and function throughout the several views. The following Figures describe embodiments of the present application and its associated features. With reference now to the Figures, embodiments of the present application are herein described. It should be noted that the articles “a”, “an”, and “the”, as used in this specification, include plural referents unless the content clearly dictates otherwise.


Referring now to FIG. 1 in the drawings, a perspective view of a cleaning assembly is illustrated. Cleaning assembly 101 includes a dispensing unit 103 and a handle assembly 105. Within the dispensing unit 103 is a plurality of tissues (not shown) that are selectively dispensed externally from the dispensing unit 103. Handle assembly 105 is configured to be obtained by a user and grasp the dispensed tissue and provide a means of exerting a force upon the tissue on a surface to be cleaned. The user is separated from the tissue, the cleaning surface, and any chemicals on the tissue at all times. The tissue may be discarded by operating the handle. As seen in FIG. 1, the handle assembly 105 includes a hook which permits it to rest on and/or hang from a portion of dispensing unit 103.


Referring now also to FIGS. 2-4 in the drawings, assorted views of handle assembly 105 are illustrated. Handle assembly 105 includes a handle 107, a shaft 109, and a clamp 111. Shaft 109 extends between handle 107 and clamp 111 and is useful to maintain separation of the user from the clamp 111. With handle 107, a user is able to grasp onto handle assembly 105 and operate clamp 111. Clamp 111 is configured to operate between an open and a closed position. In FIGS. 2 and 4, clamp 111 is closed. In FIG. 3, clamp 111 is shown in an open position.


At the base of shaft 109, clamp 111 includes a base 113 and a lower member 115. When handle 107 is actuated, lower member 115 pivots relative to base 113 along axis 117 so as to partially separate from one another. Along an upper surface of lower member 115 is a textured surface 119 to assist in grasping and holding the tissue 102. Once the tissue 102 is inserted into the open clamp 111, a user may release handle 107 and close clamp 111. The tissue is then laid onto a surface and a pad 121 along a lower surface of lower member 115 is pressed against the tissue 102 on the surface to be cleaned. As seen in the Figures, the hook 123 is located on shaft 109. It is understood that hook 123 may be located at any location on handle assembly 105 that adequately provides the capability of coupling with a portion of dispensing unit 103


Referring now also to FIGS. 5 and 6 in the drawings, a front perspective view of dispensing unit 103 is shown with a front cover removed for clarity, along with a side perspective view with a side cover removed. Front cover 120 is removed in FIG. 5 to show the internal workings of unit 103. A drum 106 is seated internally therein. Within drum 106 is a plurality of tissues 102. The tissues are preferably moistened with a chemical of some type to assist in sanitizing and cleaning. However, the tissues may be dry.


As seen in FIG. 6, unit 103 includes an actuating assembly 108 configured to facilitate the dispensing of tissues from drum 106. A plurality of gears, shafts, linkages, and other components are included within actuating assembly 108, and are coupled to a housing 128. Each is used to help ensure proper operational timing of unit 103 such that the tissues are sealed/unsealed and/or dispensed in a proper sequence. In FIG. 6, side cover 122 is removed actuating assembly 108.


Assembly 108 includes a lever 125 operable between a plurality of positions. The positions are designated as positions 125a-125d. Position 125a is a neutral position used prior to initiating any dispensing action of tissues 102. From position 125a to position 125b, the drum and tissues are unsealed. From position 125b to position 125c, the rollers 127 of assembly 108 are activated and apply a force to the tissue 102 so as to dispense it from the drum 106 externally to unit 103. The rollers 127 rotate as lever 125 is in motion between positions 125b to 125c only. Further discussion related to the operation of assembly 108 with handle 124 will be provided later with FIGS. 10 and 11.


It is understood that although a lever is disclosed, it is only meant to be a single example of a manually operated unit 103. In other embodiments, unit 103 may utilize an electronic actuating assembly 108 having a motor and a motion sensor that can automatically sense motion and then dispense a predetermined amount of tissue. Additionally, a combination of the two types may be combined into a single embodiment with a button used to select between the two types. For purposes here, a manual operation will be discussed.


Referring now also to FIGS. 7 and 8 in the drawings, views of drum 106 are provided. Drum 106 is a cylindrical body having opposing ends that are capped off. Each end has a detent 129 extending outward to assist in proper alignment of drum 106 when seating within housing 128. A notched portion 132 exists on the lower area of drum 10. In the notched portion 132 is a keyed portion 131 having a series of protrusions extending from a surface thereof. The keyed portion 131 is unique to the type of drum 106 and is useful in restricting use of unit 103 to authorized or legitimate drums 106 from the original manufacturer. Drum 106 is interchangeable from housing 128. For example, when tissues 102 run out, drum 106 may be interchanged with a separate drum. It is understood that the keyed portion 131 may have any number of different protrusions. In one embodiment it is conceived that keyed portion 131 may consist of any type of device such as an electronic device that may emit a signal for authentication. Any manual, physical, and/or electronic keyed portion 131 is conceivable.


Additionally, drum 106 includes an opening 133. Opening 133 is aligned with detents 129 to permit function within housing 128. Tissues 102 pass from an internal location within drum 106 through opening 133.


Referring now also to FIG. 9 in the drawings, a front perspective view of housing 128 is illustrated. In this Figure, drum 106 is removed for clarity. Of note is the mating portion 135 located internally. This is to match up with keyed portion 131. When the mating portion 135 and keyed portion 131 match, operation of actuating assembly 108 is permitted. In other words, operation of actuating assembly 108 is regulated by keyed portion 131 and mating portion 135 being a match or not.


Another feature of housing 128 is the use of a housing platform 137 extending from side to side of the internal cavity. Platform 137 includes a slot 139. Drum 106 is configured to align with platform 137 and slot 139 in particular. As tissues 102 leave drum 106, they are to pass through slot 139. Platform 137 also includes a seal 141 that rests on an upper surface of platform 137 and extends around slot 139. As drum 106 is located or seated within housing 128, opening 133 is seated within seal 141 above slot 139. Seal 141 is between platform 137 and drum 106. Seal 141 prevents moisture from leaving drum 106 and the drying out of tissues 102.


As noted previously, tissues 102 pass through slot 139, therefore a means of sealing slot 139 from the bottom of platform 137 is necessary. Actuating assembly 108 further includes a moving platform 143 in communication with lever 125 through one or more gears. As lever 125 actuates through positions, moving platform 143 is configured to move (i.e. pivot, rotate, translate, etc.). Moving platform 143 is configured to seat against a lower surface of platform 137 and seal around slot 139. This effectively seals out any air and moisture loss within drum 106.


Referring now also to FIGS. 10 and 11 in the drawings, enlarged front views of platform 137 and moving platform 143 are illustrated in different positions. In FIG. 10, moving platform 143 is located in a seated position against the lower surface of platform 137, thereby sealing out air from drum 106. In this position, lever 125 is in position 125a. In FIG. 11, moving platform 143 is shown in a lowered position. This occurs as lever 125 is moved to position 125b. Moving platform then stays in a lowered position until lever 125 is moved back to position 125a. Moving platform 143 remains lowered through positions 125b-125d. It is understood that the amount of movement of platform 143 can vary. Movement is necessary to release tissues 102 to allow rollers 127 to pull or dispense more tissue for a user. In position 125d, rollers 127 are not rotated and moving platform 143 is maintained in a lowered position. In this condition, drum 106 is more easily interchanged as slot 139 is open through platform 137. A new drum 106 may be inserted and tissue 102 passed through slot 139 prior to making its way through rollers 127. Once reloaded or in a ready to operate condition, lever 125 may then be rotated back up to position 125a ready for dispensing. Rollers 127 are not necessarily configured to rotate when lever 125 goes from positions 125d or 125c to 125a. rotation of rollers 127 would cause either more tissue 10 be dispensed or some tissue to be retracted. This is unnecessary although possible in selected configurations.


Referring now also to FIGS. 12 and 13 in the drawings, views of housing 128 with actuator assembly 108 and rollers 127 are provided.


Referring now also to FIGS. 14-17 in the drawings, views of actuator assembly 108 are provided. As noted previously, actuator assembly 108 includes lever 125, a plurality of gears or mechanical actuation devices, moving platform 143, and rollers 127. As lever 125 changes positions, the gears sequentially operate the moving platform 143 followed by the rollers 127. Keyed portion 131 and mating portion 135 act as a security locking device to regulate movement of lever 125 and the operation of unit 103. As seen in FIG. 15 in particular, moving platform 143 is shaped so as to seat with and match the contour of platform 137. It is understood that other shapes are possible.


Lever 125 is ideally preloaded with a set resting position in the upper position of position 125a. This means transitioning into positions 125b and 125c will have some feedback moment on the user as lever 125 naturally wants to rest in position 125a. However, in position 125d, the feedback moment of lever 125 is done away to allow for interchanging. In the preferred embodiment, lever 125 naturally stays in position 125d when placed there and until a user changes its position. In other embodiment, lever 125 may be held there by a securing device as feedback moment may be felt in all positions. If left alone, lever 125 will transition to position 125a from positions 125b and 125c.


Moving platform 143 is configured to rotate about axis 145. Springs are coupled to the axis rod to ensure a preloaded pressure in the seated position. This pressure is overcome through movement of lever 125 to position 125b.


The particular embodiments disclosed above are illustrative only, as the application may be modified and practiced in different but equivalent manners apparent to those skilled in the art having the benefit of the teachings herein. It is therefore evident that the particular embodiments disclosed above may be altered or modified, and all such variations are considered within the scope and spirit of the application. Accordingly, the protection sought herein is as set forth in the description. It is apparent that an application with significant advantages has been described and illustrated. Although the present application is shown in a limited number of forms, it is not limited to just these forms, but is amenable to various changes and modifications without departing from the spirit thereof.
