1. Field of the Invention
The subject invention relates to a portable cleaning assembly and specifically to a portable vacuum unit and waste container.
2. Description of the Related Art
In the field of industrial and office cleaning, portable cleaning assemblies having both a waste container and a vacuum unit are becoming well known. Unfortunately, these assemblies, while useful, have a propensity to tip-over due to the mass of the vacuum unit. This is particularly the case when the vacuum unit is disposed on an exterior of the waste container. Of course, damage may occur to the assembly when it tips over.
As such, the present invention is directed towards preventing the tip-over of portable cleaning assemblies.
The subject invention presents a cleaning assembly. The assembly includes a vacuum unit for creating a vacuum to clean debris from an area. At least one battery is electrically connected to the vacuum unit for supplying electrical power to the vacuum unit. The assembly also includes a waste container for collecting waste separate from the debris collected by the vacuum unit. A transport mechanism supports the waste container, the vacuum unit, and the at least one battery for moving the waste container, the vacuum unit, and the at least one battery thereof. The at least one battery is balanced with the vacuum unit for preventing tip-over of the cleaning assembly.
The balance between the at least one battery and the vacuum unit assists in preventing tip-over of the cleaning assembly. This is particularly advantageous when the waste container is completely or substantially empty and/or when the vacuum unit is mounted to an exterior of the waste container.
Other advantages of the present invention will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
Referring to the Figures, wherein like numerals indicate like or corresponding parts throughout the several views, a cleaning assembly 20 is shown herein.
Referring to
The assembly 20 also includes at least one battery 24 electrically connected to the vacuum unit 22 for supplying electrical power to said vacuum unit 22. More specifically, the at least one battery 24 is electrically connected to the motor of the vacuum unit 22. The term battery 24 herein refers to a cell for holding an electric charge, as is well known to those skilled in the art. The battery 24 may be of the many types known to those skilled in the art, such as, but not limited to, rechargeable, disposable, lead acid, and Alkaline. The at least one battery 24 is typically implemented as a plurality of batteries 24. The batteries 24 may be connected in parallel and/or series to generate a proper level of electric power to operate the vacuum unit 22. The use of the term “batteries” herein is done for convenience and does not necessarily require that multiple batteries 24 are implemented with the assembly 20.
The cleaning assembly 20 also includes a waste container 26 for collecting waste. The waste collecting in the waste container 26 is separate from the debris collected by said vacuum unit 22. (However, the debris collected by the vacuum unit 22 may, at some point, be deposited in the waste container 26.) The waste container 26 for use with the subject invention is preferably, but not limited to, a circular fifty-five or a forty-four gallon barrel. However, differently shaped and sized containers may be utilized depending upon the particular applications. The waste container 26 has an upper end 28 defining an opening 30 and a lower end 32 with a bottom 34. The opening 30 is designed to receive and secure a waste liner (not shown) and/or to store any waste deposited therein. The waste container 26 includes a sidewall 36 extending between the upper end 28 and the lower end 32. The sidewall 36 defines an interior 38 and an exterior 39 of the waste container 26. Handles (not numbered) may extend from the sidewall 36. A waste container lid (not shown) may be disposed on the upper end 28 for enclosing the waste container 26.
The cleaning assembly 20 also includes a transport mechanism 40 supporting the waste container 26, the vacuum unit 22, and the at least one battery 24. As such, the transport mechanism 40 allows portable, self-contained movement of the waste container 26, the vacuum unit 22, and the at least one battery 24 about an area. Therefore, the vacuum may be utilized to collect the debris and while allowing for independent filling of the waste container 26 with waste. The transport mechanism 40 may include wheels 42 for moving about the area, and more preferably includes at least three castors (not labeled). Of course, it is to be understood that different types of wheels 42 may be utilized depending upon the type of vacuum unit 22 and waste container 26.
The at least one battery 24 is balanced with the vacuum unit 22. More specifically, the at least one battery 24 is disposed in opposition to the vacuum unit 22 for providing the balance therebetween. By balancing the at least one battery 24 and the vacuum unit 22, a center of mass 43 of the assembly 20 is disposed generally along a center axis 44 of the transport mechanism 40. The center axis 44 extends generally perpendicular from a center point (not shown) of the transport mechanism 40.
The balance between the battery or batteries 24 and the vacuum unit 22 assists in preventing tip-over of the cleaning assembly 20. This is particularly important when the waste container 26 is completely or substantially empty.
The vacuum unit 22 may be disposed at any of several suitable locations of the assembly 20. In various embodiments, as shown in
In other embodiments, as shown in
The batteries 24 may also be disposed at any of several suitable locations of the assembly 20. In the embodiment illustrated in
In various embodiments, the batteries 24 are disposed adjacent the sidewall 36 of the waste container 26. The batteries 24 may be located at the exterior 39 of the waste container 26, within the interior 38 of the waste container 26, or a combination of both.
The batteries 24 may be supported by an apron 50 having one or more pockets 52. Each pocket 52 of the apron 50 may hold and enclose one or more batteries 24. Preferably, each pocket 52 is sized to hold a single battery 24. However, other sizing of the pockets 52 may alternative be acceptable. The apron 50 may be formed of fabric, plastic, or other suitable material. As such, the apron 50 may be flexible or rigid. The apron 50 may be shaped as a flat sheet that conforms to the shape it is held against. For instance, the apron 50 may be shaped to conform to the sidewall 36 of the waste container 26.
In the embodiment shown in
The apron 50 may be configured to cover a majority or the entirety of the surface defined by the sidewall 36 of the waste container 26. As shown in
In other embodiments, the apron 50 may be disposed adjacent to the sidewall 36 on only the exterior 39 of the waste container 26, as shown in
The apron 50 may also be utilized to hold other objects (not shown) besides the batteries 24. For instance, the apron 50 could also hold cleaning supplies. A single apron 50 could be utilized to hold the batteries 24 and the other objects. Alternatively, as shown in
The batteries 24 may also be disposed in a plurality of tubes 57, as shown in
The batteries 24 may also be positioned below the waste container 26. In some embodiments, the batteries 24 may be enclosed by the transport mechanism 40. In other words, the batteries 24 are integrated with the transport mechanism 40. Furthermore, the batteries 24 may be located both within the transport mechanism 40 and within the apron 50, as shown in
The batteries 24 may also be integrally molded into the waste container 26 or transport mechanism 40. This is particularly advantageous with rechargeable batteries 24 that need not be removed. The assembly 20 may also include charging circuits (not shown) electrically connected to the batteries 24 for charging the rechargeable batteries 24. As such, the assembly 20 may be plugged-in to commercial power to recharge the batteries 24 when the assembly 20 is not in use.
With the vacuum unit 22 disposed on the outside, i.e., exterior 39, of the waste container 26, the locations of the batteries 24 for the assembly 20 are critical for the balance of the assembly 20 to prevent tip over as well as functionality. With the batteries 24 in opposition to the vacuum unit 22, as shown in
Referring to
The transport mechanism 40 may have an irregular shape. For instance, the side 60 of the transport mechanism 40 may extend past the sidewall 36 of the waste container 26, as shown in
Preferably, heat generated by the batteries 24 is dissipated to maintain battery life and for safety reasons (e.g., prevent fires, melting of plastics, etc.) Referring to
It is preferred that the aprons 50 define passages (not numbered) between the pockets 52 to distribute the exhaust air therethrough. More preferably, the passages are defined such that each battery 24 receives exhaust air from the vacuum unit 22. The passages may be voids formed between the pockets 52. Alternatively, the passages may be implemented with a breathable fabric that forms at least part of the pockets 52 and/or the apron 50. Of course, those skilled in the art realize other techniques for forming such fluidic passages between the pockets 52.
It is also preferred that the exhaust air exits the apron 50 in a downward direction. This downward airflow prevents dust and debris from being thrown up into the air.
Additionally, passageways may be formed in the other battery 24 supporting configurations, e.g., in the transport mechanism 40, in the tubes 57, or in the rack 58. This is especially critical where the batteries 24 are separated from one another using dividing walls, partitions, or other such obstructions.
The present invention has been described herein in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. Obviously, many modifications and variations of the invention are possible in light of the above teachings. The invention may be practiced otherwise than as specifically described within the scope of the appended claims.
