DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Selected exemplary embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the exemplary embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

As shown in FIGS. 1-5, a vacuum cleaner assembly 10 in accordance with an exemplary embodiment of the present invention includes a vacuum cleaner 12 and a handheld vacuum cleaner 14. The handheld vacuum cleaner 14 is removably connected to the vacuum cleaner 12.

The vacuum cleaner 12 includes a suction head or base 16, a housing 18 for receiving debris, a handle 20, and a power cord 22 for connecting the vacuum cleaner 12 to a source of electrical power. The housing 18 includes a dust bin 46, such as a vacuum bag or any other suitable apparatus, for receiving dirt, dust or other debris collected during operation of the vacuum cleaner 12. The vacuum cleaner 12 can be any suitable type of vacuum cleaner, such as, but not limited to, direct air and bypass air upright vacuum cleaners, canister vacuum cleaners, stick vacuum cleaners and multi-surface vacuum cleaners. The various components and interactions of the vacuum cleaner 12 would be understood by one of ordinary skill in the art.

The base 16 includes a plurality of wheels 24 rotatably connected to the base 16 to facilitate pushing and pulling the vacuum cleaner 12 during operation. A surface agitator 26, such as a brush roll, is movably disposed in the base 12. A suction inlet 28 is disposed in the base 16 in association with the surface agitator 26. A first suction path 30 extends from the suction inlet 28 in the base 16, through a passage 32 in an intake tube 34 to the dust bin 46 disposed in the housing 18, as shown in FIG. 5.

The handle 20 is connected to an upper end of the intake tube 34. The handle 20 can be removably connected to the upper end of the intake tube 34 of integrally formed therewith as a one-piece assembly. The intake tube 34 includes an upper cord hook 36 and a lower cord hook 38 around which the power cord 22 can be wrapped when storing the vacuum cleaner assembly 10.

A suction motor 40 is disposed in the base 16 of the vacuum cleaner 12, as shown in FIG. 5. Alternatively, the suction motor 40 can be disposed elsewhere, for example in the body of the vacuum cleaner 12 or in any other suitable location. The suction motor 40 generates a suction force, as shown in FIG. 5, to create flow through the first suction path 30. The flow of the first suction path 30 is from the suction inlet 28 in the base 16, through the passage 32 in the intake tube 34, and into the housing 18. The motor 40 also drives the surface agitator 26. Alternatively, a separate motor can be used to drive the surface agitator 26. The suction motor 40 is configured to be powered by a first power source, such as an electrical outlet 270 (FIG. 10).

A second inlet 42 can be disposed in the base 16, as shown in FIG. 5. The second inlet 42 is in fluid communication with the first suction path 30. A cover 44 is movably connected to the base 16 to move between a closed position covering the second inlet 42 and an open position allowing fluid to flow through the second inlet 42. When the cover 44 is in the closed position (shown in solid lines in FIG. 5), fluid flow through the second inlet 42 is substantially prevented. When the cover 44 is in the open position (shown in dashed lines in FIG. 5), air flows through the second inlet 42 to the first suction path 30, thereby generating fluid flow through the second inlet 42 and relieving suction through the first inlet 28. When powered during operation of the vacuum cleaner 12, air is drawn into the first suction path 30 through the first inlet 28 in the base 16. When the cover 44 is in the open position, air is drawn into the suction path 30 through the first inlet 28 and through the second inlet 42. By relieving the suction through the first inlet 28, the vacuum cleaner 12 becomes easier to push and pull such that the mobility of the vacuum cleaner 12 will be easier for the user. Additionally, slowing down or stopping the surface agitator 26 is relieved or eliminated.

The dust bin 46, such as a vacuum bag, is disposed in the housing 16, as shown in FIG. 5. The first suction path 30 flows into and through the dust bin 46, thereby trapping dust, dirt and other debris carried through the first suction path 30 inside the dust bin 46. The housing 18 can be opened to discard a full dust bin 46, and to attach a new dust bin 46. Alternatively, the dust bin 46 can be integrally formed with the housing 16, and emptied and cleaned in any suitable manner.

Any of the exemplary embodiments and/or elements disclosed herein may be combined with one another to form various additional embodiments not specifically disclosed. Accordingly, additional embodiments are possible and are intended to be encompassed within this specification and the scope of the appended claims. The specification describes specific examples to accomplish a more general goal that may be accomplished in another way.

In understanding the scope of the present invention, the term “comprising” and its derivatives, as used herein, are intended to be open ended terms that specify the presence of the stated features, elements, components, groups, integers, and/or steps, but do not exclude the presence of other unstated features, elements, components, groups, integers and/or steps. The foregoing also applies to words having similar meanings such as the terms, “including”, “having” and their derivatives. Also, the terms “part,” “section,” “portion,” “member” or “element” when used in the singular can have the dual meaning of a single part or a plurality of parts unless otherwise stated.

As used herein, the following directional terms “forward”, “rearward”, “front”, “rear”, “up”, “down”, “above”, “upper”, “below”, “lower”, “upward”, “upwardly”, “downward”, “downwardly”, “top”, “bottom”, “side”, “vertical”, “horizontal”, “perpendicular” and “transverse” as well as any other similar directional terms refer to those directions of a vacuum cleaner in an upright position for use. Accordingly, these directional terms, as utilized to describe the vacuum cleaner should be interpreted relative to a vacuum cleaner in an upright position on a horizontal surface. The terms “left” and “right” are used to indicate the “right” when referencing from the right side as viewed from the rear of the vacuum cleaner, and the “left” when referencing from the left side as viewed from the rear of the vacuum cleaner.

Also, it will be understood that although the terms “first” and “second” may be used herein to describe various components, these components should not be limited by these terms. These terms are only used to distinguish one component from another. Thus, for example, a first component discussed above could be termed a second component and vice versa without departing from the teachings of the present invention. The term “attached” or “attaching”, as used herein, encompasses configurations in which an element is directly secured to another element by affixing the element directly to the other element; configurations in which the element is indirectly secured to the other element by affixing the element to the intermediate member(s) which in turn are affixed to the other element; and configurations in which one element is integral with another element, i.e. one element is essentially part of the other element. This definition also applies to words of similar meaning, for example, “joined”, “connected”, “coupled”, “mounted”, “bonded”, “fixed” and their derivatives. Finally, terms of degree such as “substantially”, “about” and “approximately” as used herein mean an amount of deviation of the modified term such that the end result is not significantly changed.

While only selected embodiments have been chosen to illustrate the present invention, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made herein without departing from the scope of the invention as defined in the appended claims. For example, unless specifically stated otherwise, the size, shape, location or orientation of the various components can be changed as needed and/or desired so long as the changes do not substantially affect their intended function. Unless specifically stated otherwise, components that are shown directly connected or contacting each other can have intermediate structures disposed between them so long as the changes do not substantially affect their intended function. The functions of one element can be performed by two, and vice versa unless specifically stated otherwise. The structures and functions of one embodiment can be adopted in another embodiment. It is not necessary for all advantages to be present in a particular embodiment at the same time. Every feature which is unique from the prior art, alone or in combination with other features, also should be considered a separate description of further inventions by the applicant, including the structural and/or functional concepts embodied by such feature(s). Thus, the foregoing descriptions of the exemplary embodiments according to the present invention are provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
