The invention described in this document relates generally to pneumatic cleaners (vacuums, blowers, etc.), and more particularly to vacuum cleaners that can be mounted onto a wall bracket.
It is often useful to be able to mount small- and medium-sized vacuum cleaners or blowers to a wall or other surface so that they are out of the way when not in use but are also in a convenient and readily accessible location when needed. Various brackets and shelves have been used in the past. Many prior solutions are imperfect because they are difficult for some consumers to install and may be expensive to manufacture.
The new vacuum cleaner/bracket combination that has been developed includes a bracket that mates with an indented side on a vacuum cleaner or blower. The indented side has a downwardly-facing upper lip portion and a laterally-facing side lip portion. There is an upper groove portion behind the downwardly-facing upper lip portion, and a side groove portion behind the side lip portion.
The bracket has an upper rim portion that is configured to fit within the upper groove portion on the indented side. A side rim portion on the bracket is positioned below the upper rim portion. It is configured to fit within the side groove portion on the indented side when the upper rim portion on the bracket fits within the upper groove portion.
The invention may be better understood by referring to the accompanying drawings, in which:

The indented side and the bracket will be discussed in more detail below. The general arrangement of the vacuum cleaner, apart from the indented side described below, is not important to the way the bracket works.
General Arrangement of the Illustrated Vacuum Cleaner
The invention can be used with many types of vacuum cleaners, including single-piece, handheld vacuums. The illustrated vacuum cleaner 10 has both a vacuum head 12 and a separable vacuum tank 14. The illustrated vacuum head 12 powers the vacuum cleaner, and has a motor and an air impeller (not depicted). The head mounts onto and seals against the vacuum tank 14. The tank holds debris collected by the vacuum cleaner.
The illustrated vacuum tank 14 is manufactured as a single piece of rigid plastic. Single-piece construction can minimize the amount of time and effort to produce the tank. It may also be preferred for making the indented side. However, one-piece construction is not always required. In some circumstances, two-piece tanks or other designs may also be used. Rigid plastic is conducive to true one-piece construction, and may sometimes be preferred for that reason. However, a variety of materials other than rigid plastic can also be used.
The rim 28 on the illustrated tank 14 is profiled to correspond with a lip 38 (
The inlet 30 is used for attaching a hose to the illustrated vacuum cleaner 10, and may have a conventional design. The illustrated inlet has a reinforced design, and can withstand the forces associated with installing and removing the vacuum hose from the tank 14 during usage.
The Indented Sides
The right and left sides 18 and 20 of the illustrated vacuum cleaner 10 each have an indentation 40 that can be used for mounting the vacuum cleaner to the illustrated wall bracket 16. The indentation could also be on other sides of the tank 14, or on other parts of the vacuum cleaner, such as a side on the illustrated vacuum head 12. While two indentations are shown in this example, only one indentation may be needed.
In general, a lower portion 41 of the illustrated indentation 40 is nearly flush with the side 18 of the vacuum cleaner 10. An upper portion 42 of the indentation has a downwardly-facing upper lip portion 58 and two opposed laterally-facing side lip portions 60. An upper groove portion 46 can be found behind the upper lip portion, and a side groove portion 48 (
For manufacturing ease, the side lip portions 60, the upper lip portion 58, and adjacent portions of the illustrated vacuum cleaner 10 are all part of an integral molding. This is not always required.
In this example, the lip portions 58, 60 form a continuous lip that has a three-sided shape seen in
Similarly, this example shows edges of the side lip portions 60 extending toward each other; in other words, there is an empty space in front of the vacuum cleaner 10 between the right edge of the left side lip portion and the left edge of the right side lip portion. In some circumstances, the edges of the side lip portions could be arranged to extend away from each other, so that the right side of the left side lip and the left side of the right side lip are the sides that transition into the rest of the vacuum cleaner 10.
In this example, the side lip portions 60 both extend down several inches from the lateral ends of the upper lip portion 58. This downward extension helps to provide lateral stability to the vacuum cleaner 10 while it is hung from the bracket 16, and will be discussed in more detail below. In this example, the side lip portions extend almost to the bottom of the vacuum cleaner. Other arrangements are possible.
The Bracket
The wall bracket 16 holds the vacuum cleaner 10. Specifically, the bracket is shaped to mate with one of the indentations 40 on the sides 18, 20 of the vacuum cleaner. The bracket may be molded in one piece of rigid plastic, or in some other suitable material. Again, however, neither one-piece construction nor the use of rigid plastic is required. Many alternatives are possible, including, for example, the use of steel or aluminum.
The bracket 16 seen in
The slope of the illustrated side rim portions 68 on the bracket 16 and of the illustrated side lip portions 60 on the vacuum cleaner allow the components to carry at least some of the weight of the vacuum cleaner. Thus, portions of these elements could serve as upper lip portions or upper rim portions.
The illustrated bracket 16 has an upper rim portion 66 that carries at least a portion of the weight of the vacuum cleaner 10. To do this, the upper rim portion is configured to fit within the upper groove portion 46 on the side of the vacuum cleaner. The upper rim of the illustrated bracket extends upwardly and forwardly from the base 62 of the bracket, and has a sloped rear face. The lateral spacing between the back of the base of the bracket and the uppermost edge of the upper rim portion of the bracket is greater than the thickness of the upper lip portion 58 on the vacuum cleaner, and the lateral spacing between the lowermost edge of the upper lip portion of the vacuum cleaner and the side of the vacuum cleaner (i.e., the width of the upper groove portion 46) is greater than the thickness of the upper rim portion of the bracket.
Side rim portions 68 on the illustrated bracket 16 help to provide lateral stability to the mounted vacuum cleaner 10. To provide this stability, the side rim portions are configured to fit within the side groove portions 48 on the vacuum cleaner 10. The side rim portions of the illustrated bracket extend laterally (in opposed directions) and are positioned forwardly from the back of the base 62 of the bracket. The lateral spacing between the back of the base of the bracket and the outermost edge of the side rim portions of the bracket is greater than the thickness of the side lip portions 60 of the vacuum cleaner, and the lateral spacing between the edges of the side lip portions and the side of the vacuum cleaner (i.e., the width of the side groove portions 48) is greater than the thickness of the side rim portions of the bracket.
The lowermost side rim portions 68 of the bracket 16 seen in
Although it is not always necessary, the laterally-facing side rim portions 68 of the illustrated bracket 16 ascend toward each other; i.e., the upper portions of the side rim portions are closer together than the lower portions are. When combined with the side rim portions extending away from each other, this configuration helps to provide a gradual locking of the illustrated vacuum cleaner 10 onto the bracket as the vacuum cleaner is lowered onto the bracket. A gradual locking is also aided by the sloping back surfaces of the groove portions 46, 48 of the indentation 40 and of the rim portions on the bracket. As the rim and lip portions engage further, the sloping back surfaces slide together, creating a tighter fit.
In the alternative embodiment of a bracket seen in
In both illustrated examples of suitable brackets, the side rim portions 68, the upper rim portion 66, and surrounding portions of the bracket are all part of an integral molding. This arrangement can simplify molding and improve efficiency.
In these examples, both lateral sides of the base 62 of the bracket 16 taper toward the center line of the bracket as they progress upwardly. In other circumstances, it might be possible for one lateral side or the other to taper away from the center line, so long as the distance between the two lateral sides is no greater at the top of the bracket than it is at the bottom.

Hanging the Vacuum Cleaner on the Bracket
To mount the illustrated vacuum cleaner 10 onto the illustrated bracket 16, the vacuum cleaner 14 is first positioned with the upper rim portion 66 of the bracket 16 between the top and the bottom of one of the indentations 40 on the side of the vacuum cleaner. In this position, the upper rim portion of the bracket fits between the side lip portions 60 on the vacuum cleaner. The vacuum cleaner can then be lowered, moving the lip portions 58, 60 of the vacuum cleaner behind the rim portions 66, 68 on the bracket until the upper rim portion 66 stops and locks into the upper groove portion 46 on the vacuum cleaner, and the upper lip portion 58 on the vacuum cleaner rests against the upper rim portion 66 of the bracket. As the vacuum cleaner is lowered, the side rim portions 68 of the bracket 16 slide into the side groove portions 48 of the vacuum cleaner, with the slope of the back sides causing the fit to progressively tighten. This provides good lateral support.
In this case, the taper of the side groove portions 48 on the indentation 40 and the taper of the side rim portions 68 of the bracket 16 both help to direct the wall bracket into the indentation so that it seats properly, and provide additional security. In other embodiments, one or the other of these components, or both, might not be tapered.
When the illustrated vacuum cleaner 10 is mounted on either of the illustrated brackets 16, 16′, it is in an inherently stable and secure position. The vacuum cleaner can be removed by lifting it upwardly to disengage the rim portions 66, 68 from the groove portions 46, 48 of the indentation 40.
