The housing 1 1 1 , 1 15 may be a hard plastic or any suitable material(s). The housing 1 1 1 , 1 15 may include an upper portion 1 1 1 and a lower portion 1 15. The lower portion 1 15 may couple with the nozzle 1 14 on a first end and the upper portion 1 1 1 on a second end. In various embodiments, the lower portion 1 15 may be tapered such that the first end has a narrower diameter than the second end. In certain embodiments, the upper portion 1 1 1 and lower portion 1 15 of the housing may be detachably coupled, fixably coupled, or integrated as a single piece, among other things. The upper portion 1 1 1 may comprise a first end, second end, top side, and underside. The first end of the upper portion 1 1 1 may couple to the second end of the lower portion 1 15. The second end of the upper portion 1 1 1 may comprise the fan opening 1 13. The top side of the upper housing 1 1 1 may include a handle connection base 1 12 configured to pivotally attach with the handle portion 120 at a handle pivot 122 as described below.

[0019] In various embodiments, the top side of the upper portion 1 1 1 may include electrical connections and an attachment mechanism for receiving a battery 130. Additionally and/or alternatively, the electrical connections and attachment mechanism for the battery 130 may be placed in any suitable position on or in the tool portion housing 1 1 1 , 1 15. The attachment mechanism may be grooves configured to slidably receive ridges in a battery 130, or any suitable attachment mechanism. In various embodiments, the apparatus 100 may be configured with an enclosure- free battery 130. For example, the battery 130 may snap, slide, or otherwise directly and securely connect with the electrical connections on the tool portion housing 1 1 1 , 1 15 without including a housing or other enclosure for the battery 130. In an exemplary embodiment, the tool portion housing 1 1 1 , 1 15 and/or the battery 130 may comprise a release for releasing the battery 130 from its secure connection to the electrical connections on the tool portion housing 1 1 1 , 1 15. The release may be a button, tab, or any suitable mechanism for engaging and disengaging the battery 130 with the tool portion housing 1 1 1 , 1 15. [0020] The handle portion 120 may comprise a grip 121 , a handle pivot 122, and a user input control 123. The grip 121 may have a first end and a second end. The handle pivot 122 may be coupled to the first end of the grip 121 and the user input control 123 may be coupled to the second end of the grip 121 , for example. The grip 121 may be a curved portion (e.g., generally banana-shaped) extending from the handle connection base 1 12 of the tool portion 1 10 forward toward the nozzle 1 14 of the tool portion 1 10. The grip 121 may comprise an elastomer or any suitable material arranged over a hard plastic base, or any suitable material, to provide a comfortable, non-slip surface for grasping by a user.

[0021] The handle connection base 1 12 of the tool portion 1 10 may be pivotally coupled to the grip 121 at the handle pivot 122. For example, the tool portion 1 10 may be pivotable up and down as shown by exemplary tool portion positions 140, 150. The pivotability of the tool portion 1 10 with respect to the handle portion 120 provides enhanced efficacy of the handheld air movement apparatus 100. For example, directional height adjustments provided by the handle pivot 122 allow the nozzle 1 14 of the tool portion 1 10 to be positioned adjacent to its target, providing enhanced performance of the apparatus 100 based on the close proximity of the air flow source to the target. Additionally and/or alternatively, the pivotability of the tool portion 1 10 with respect to the handle portion 120 provides enhanced comfort to the user of the handheld air movement apparatus 100. For example, irrespective of the directional height adjustments provided by the handle pivot 122 to allow the nozzle 1 14 of the tool portion 1 10 to be positioned adjacent to its target, the position of the handle portion may remain constant in a natural grip position of the user. In various embodiments, the handle portion 120 maintained in the natural grip position of the user provides a proper weight distribution of the handheld air movement apparatus 100. Various embodiments enable a user to maintain a natural grip position at the handle portion 120 with a proper weight distribution of the apparatus 100 while maneuvering the tool portion 1 10 to a desired position 140, 150.

[0022] The handle pivot 122 may be and/or include one or more mechanisms for securing and releasing the handle connection base 1 12 of the tool portion 1 10 to the grip 121 of the handle portion 120. The handle pivot 122 and/or an associated rotation release mechanism 126 may be a spring loaded mechanism or any suitable mechanism for (1 ) releasing the handle connection base 1 12 of the tool portion 1 10 to allow the tool portion to pivot up and/or down with respect to the handle portion 120, and (2) locking the handle connection base 1 12 of the tool portion 1 10 in a locked position after selection of a tool portion 1 10 position and/or orientation. For example, the handle pivot 122 may have one or more buttons 126 that are depressed to allow the handle connection base 1 12 of the tool portion 1 10 to pivot. In various embodiments, the handle pivot 122 may include detents to provide pre-defined positions 140, 150. The one or more buttons 126, once released, may lock the tool portion 1 10 in the position 140, 150 at the time of the button release. As an example, the buttons 126 may include or be directly or indirectly coupled with protrusions that may extend into detents corresponding with pre-defined tool portion 1 10 positions 140, 150. Although two tool portion 1 10 positions 140, 150 are shown in FIGS. 1 and 2, any number of positions greater than or equal to two is contemplated.

[0023] In various embodiments, the tool portion 1 10 may be pivoted with respect to the handle portion 120 at the handle pivot from 0 degrees as shown in FIG. 1 to 45 degrees as shown in FIG. 2. Although two tool portion 1 10 positions 140, 150 are shown in FIGS. 1 and 2, any number of positions between and including the two positions 140, 150 is contemplated. For example, the handle pivot 122 may include pre-defined positions 140, 150 at 0 degrees, 15 degrees, 30 degrees, and/or 45 degrees. As another example, the handle pivot 122 may include pre- defined positions 140, 150 at 0 degrees, 10 degrees, 20 degrees, 30 degrees, and/or 40 degrees. Although various tool portion 1 10 positions 140, 150 are discussed above, any suitable positions 140, 150 are contemplated. In certain embodiments, any suitable position 140, 150 between and/or including 0 degrees 150 and 45 degrees 140 may be dynamically selected. For example, the handle pivot 122 may include a protrusion for press fitting the handle connection base 1 12 of the tool portion 1 10 to the grip 121 of the handle portion 1 20 in a dynamically selectable location within a predefined range, such as from 0 to 40 degrees, from 0 to 45 degrees, or any suitable range.

[0024] The user input control 123 may be coupled to and/or integrated with the grip 121 at the second end of the grip 121 , for example. The user input control may comprise a trigger 124. The trigger 124 may extend from one or more of the user input control 123 or the 121 . The trigger 124 is configured to start an air movement action by the tool portion 1 10 when the trigger 124 is depressed and to stop the air movement action when the trigger 124 is released. The trigger 124, for example, may be coupled by electrical wires to the tool portion 1 10. The electrical wires may run through a hollow portion of the handle portion 120. In various embodiments, the hollow portion of the handle portion 120 may include sheathing to protect the wiring. In an exemplary embodiment, the user input control 123 may include a boost button 125 for providing increased air movement over the normal operating condition of the tool portion 1 10. The boost button 125 may be coupled to the tool portion 1 10 by electrical wires that run through the hollow portion of the handle portion 120 with the trigger 124 electrical wires.

[0025] In various embodiments, the handheld air movement apparatus 100 having ergonomic gripping mechanisms 120 provides a natural grip orientation that affords anthropometric advantage over existing handheld air movement apparatus grips by providing a more natural grip position and improved weight distribution. For example, the ability of the tool portion 1 10 to pivot with respect to the handle portion 120 provides a more natural gripping position compared with fixed handles of typical handheld air movement apparatuses that are maneuvered to direct the nozzle of the tool by twisting a user's wrist and/or otherwise raising and lowering the apparatus. Moreover, the adjustability of the tool portion position 140, 150 improves the performance of the apparatus 100 by allowing the nozzle 1 14 to be placed closer to a target (e.g., leaves or grass trimmings at ground level or cobwebs in bushes at chest level). More specifically, the closer the nozzle 1 14 of the apparatus 100 is to its target, the more force or suction is received at the target.

[0026] Aspects of the present disclosure provide a handheld air movement apparatus 100. The apparatus 100 may comprise a handle portion 120 and a tool portion 1 10. The handle portion 120 may comprise a grip 121 , a user input control 123, and a handle pivot 122. The grip 121 may include a first end and a second end.
