Not applicable.
The present invention relates generally to toolboxes used by homeowners, handymen, tradesmen, and craftsmen.
The applicants have developed a new product that combines a toolbox with a vacuum cleaner.
Like prior known toolboxes, the toolbox section on the new product is sized to accommodate hand tools. It has a top that is hinged to one of two upright sides, and has an internal storage space that can be used for storing and transporting hand tools and supplies.
Like prior known vacuum cleaners, the vacuum cleaner section on the new product has a vacuum source that draws dirt or debris through an inlet, a receptacle in which the dirt or debris is retained, latches that releasably retain the receptacle in place, and an inlet port that is adapted to be connected to a vacuum hose that can be manually directed by a user and used to draw in dirt and debris from selected locations.
Unlike prior known toolboxes and vacuum cleaners, the new product has mating connectors on upright mounting walls on the toolbox section and the vacuum cleaner section that enable the vacuum cleaner section to releasably attach to the toolbox section. Upright side walls on the vacuum cleaner section extend from the mounting wall on the vacuum cleaner section and align with the upright sides on the toolbox section. An interacting tab and slot on the mounting walls prevent the vacuum cleaner section from being removed from the toolbox section when the top on the toolbox section is closed.
Specific mounting features have been developed. A downward-facing tongue can be provided on one of the mating surfaces, with a corresponding horizontal slot being provided in the other of the mating surfaces. At least one vertical slot may be provided in the tongue, corresponding with a vertical flange adjacent the corresponding slot. The elements may be arranged so that the two sections attach in a position in which an extended horizontal work surface is formed by portions of the hinged top on the toolbox section and the vacuum cleaner section. Mounts may be provided so that vacuum tools are detachably mounted in the storage space in the top on the toolbox section.
The interacting tab can be provided on the mounting wall on the vacuum cleaner section, where it is covered by a lip on the top when the vacuum cleaner section and the toolbox section are attached together and the top is closed.
Other features have also been developed. A handle on the vacuum cleaner section can be arranged to move between an extended position and a retracted position, with a side portion of this handle forming a part of the horizontal work surface when the handle is in the retracted position.
To provide more functionality, a recessed channel can be provided in the horizontal work surface. That part of the work surface may also be provided with parallel lateral grooves that have a depth less than the depth of the recessed channel, and have co-linear segments on opposite sides of the recessed channel.
A power switch on the vacuum cleaner section can be arranged so that it is accessible to a user while the vacuum cleaner section is connected to the toolbox section.
In one particular arrangement, wheels are provided on a lower back portion of the toolbox section, and a mount is positioned forwardly of the mounting wall and above mid-height of the mounting wall. A handle is hinged to the mount and enables a user to conveniently pull the combined toolbox and vacuum cleaner while it rolls on the wheels. In this arrangement, the length of the handle may be less than the height of the mount above the bottom of the toolbox section, and the toolbox section can be provided with a pocket that extends forwardly from the mounting wall and encircles and supports the vacuum cleaner section when the vacuum cleaner section is connected to the toolbox section.
In another arrangement, a retractable handle on the toolbox section can be arranged to fit in the recessed channel. In this arrangement, a side access slot can be provided adjacent to the recessed channel to facilitate moving the handle from the retracted position. A lower edge of the access slot is adjacent to and lower than a downward-facing edge on the handle.
In this arrangement, hinges between the top on the toolbox section and the side wall can also be mounted at an elevation halfway between the bottom of the toolbox section and the top of the extended handle on the toolbox section. The handle can then support the top against the ground when the top is fully open and the handle is in the extended position.
The invention may be better understood by referring to the accompanying drawings, in which:
Two related embodiments of portable combined toolbox and vacuum cleaners are seen in the figures. The embodiment 10 seen in
Elements Illustrated in Both Embodiments
In this section, structural elements that are common to both of the illustrated embodiments will be discussed. Discussion in this section will focus on the wheeled embodiment 10, but each element and function discussed in this section has a corresponding element and function in the other embodiment 10′.

On some occasions, the user may want to separate the vacuum cleaner section 14 from the toolbox section 12 (for example to reduce weight or bulk). For those situations, the illustrated embodiment includes an optional handle 58 on the vacuum cleaner section. Although the illustrated handle moves between an extended position and a retracted position, fixed handles or handgrips might also be used in some embodiments.
The Attaching Components
The two mounting walls 20 and 52 on the vacuum cleaner section 14 and the toolbox section 12 are provided with mating connectors that enable the vacuum cleaner section to releasably attach with the toolbox section. In the illustrated example, these connectors take the form of a downward-facing tongue 60 on one of the mating surfaces (
The illustrated tongue 60 is relatively wide. The outer ends of the illustrated tongue are separated by more than ¼ the width of the mounting wall 20 or 52. This width helps to maintain stability of the connection between the two sections. As best seen in
In this embodiment, both the tongue 60 and the flanges 66 and the spaced wall 64 that form the groove 62 are all integrally molded into the respective mounting walls 20, 52. In other embodiments, comparable connectors may be attached to the mounting walls by adhesive, mechanical fasteners, etc. In many cases, however, integral molding will facilitate manufacture.

The Extended Work Surface
As seen in
In the illustrated embodiment 10, a recessed channel 76 is provided in the part of the horizontal work surface 16 that is formed by the portion of the hinged top 26 on the toolbox section 12. This recessed channel extends the full length of the toolbox section, and thus enables a user to support narrow items such as pipe or trim in the channel with one end of the item projecting beyond the end of the toolbox section for cutting, finishing, or marking. Longer items can be supported in the channel by removing the vacuum cleaner section 14 and extending the ends of the work piece beyond both ends of the toolbox section.
Downward lateral grooves 78 in the top of the toolbox section 12 can also provide benefits without obstructing the work surface. The illustrated parallel lateral grooves are perpendicular to the recessed channel 76, increasing the strength of the top. The grooves have a depth less than the depth of the recessed channel and have co-linear segments on opposite sides of the recessed channel. A user can use the grooves to align items parallel to each other, or perpendicular to the recessed channel.
Elements Illustrated in just the Wheeled Arrangement
Unlike the embodiment seen in the other figures, the combination toolbox and vacuum cleaner 10 seen in
As seen in
The illustrated pocket 84 is sized to receive a portion of the vacuum cleaner section 14, such as the receptacle 48. The pocket laterally encircles and supports the vacuum cleaner section while the combined sections of the embodiment 10 are moved, while still allowing a user to remove the vacuum cleaner section by lifting it vertically. The illustrated pocket fully encircles the vacuum cleaner section, but this is not always required. For example, the mounting wall 52 of the vacuum cleaner section may directly adjoin the mounting wall 20 of the toolbox section 12, allowing the use of a c-shaped pocket that opens toward the toolbox section. While the vacuum cleaner section in such an arrangement is still fully encircled (by the pocket and the mounting wall on the toolbox section), the pocket could also be arranged to support the vacuum cleaner section without fully encircling the vacuum cleaner section. For example, a pocket that provides sufficient bottom support of the vacuum cleaner section may need only a few narrow, spaced side wall segments to encircle the vacuum cleaner section sufficiently to block lateral movement.
The handle 80 is hinged to a mount 88 on the pocket 84. As best seen in
The length of the illustrated handle 80 is less than the height of the mount 88 above the bottom of the toolbox section 12. This length limit helps to ensure that the combined elements of the embodiment 10 easily fit within limited confines, such as a truck bed or shipping container. The relatively high position of the mount helps to accommodate a longer handle than could otherwise fit within the same confines, and also further helps to stabilize the embodiment when a user is rolling it across the ground.

Elements Illustrated in just the Other Embodiment
The embodiment 10′ seen in
In the retracted position, a portion 104 of the handle 100 fits in the recessed channel 76′. In the retracted position, this handle does not intrude upon or limit the horizontal work surface 16′. Indeed, side portions 106 of the illustrated handle form parts of the horizontal work surface.
A user can easily access the handle 100 to move it from the retracted position to the extended position. The user can access the illustrated handle through a side access slot 108 that is in the top 26′ of the toolbox section 12′, adjacent to the recessed channel 76′. As seen in
