The various advantages of the exemplary embodiments will become apparent to one skilled in the art by reading the following specification and appended claims, and by referencing the following drawings, in which:
One or more embodiments set forth, described, and illustrated herein relate to a portable backpack vacuum that includes an upper housing that forms a vacuum body, a lower housing that forms a dust tank and which is detachably connected to the upper housing, and a harness member that is pivotably connected to the upper housing to facilitate support of the portable backpack vacuum by a user. The harness member comprises a fold-in harness that is pivotably connected to the upper housing via one or more connection members in a manner that facilitates support of the portable backpack vacuum on a support surface when the lower housing is selectively removed from the upper housing (e.g., in order to remove its contents). In particular, when the lower housing is removed, the harness member is operable to pivot or fold-in relative to the support surface to facilitate support of the upper housing on the support surface.
As illustrated in
As illustrated in
The vacuum motor is in fluidic communication with a vacuum hose connector 114 serving as an air inlet arranged at a sidewall of the upper housing body 111. The vacuum hose connector 114 is in fluidic communication with a flexible suction hose member (not illustrated) that is operable to capture dust, debris, particles, etc. using the negative pressure generated by the vacuum motor. When the example portable backpack vacuum 100 is not in use (e.g., after a cleaning sequence has been conducted), the vacuum hose connector 114 may be covered by a vacuum hose connector cap 115.
A rear sidewall of the upper housing body 111 has a surface at an upper region thereof that forms a first connection interface 116 to facilitate connection with a pair of shoulder support members 131 of the harness member 130. The first connection interface 116 may include one or more holes to receive a corresponding mechanical fastener of the harness member 130 or a connection member 133, 134. The rear sidewall of has a surface at a lower region thereof that forms a second connection interface 118 that facilitates connection with a waist support member 132 of the harness member 130. The second connection interface 118 may include one or more holes to receive a corresponding mechanical fastener of the harness member 130 or one or more connection members 133, 134. Although the illustrated embodiment illustrates use of mechanical fasteners, this disclosure contemplates use of any suitable configurations that facilitate connection of the harness member 130 to the upper housing body 111 in a manner that optimizes the performance of the example portable backpack vacuum 100 and falls within the spirit and scope of the principles of this disclosure.
When the example portable backpack vacuum 100 is not in use (e.g., after a cleaning sequence has been conducted) and the lower housing body 121 is selectively detached and removed from its connection with the upper housing body 111, the peripheral bottom edge(s) 119 of the sidewalls of the upper housing body 111 may facilitate support of the upper housing body 111 on a support surface.
A cover member 140 having a cover member body 141 that is detachably connected via one or more upper latch members 113 to the upper housing 110 to enclose the interior space 112. In accordance with one or more embodiments set forth, shown, and described herein, the cover member body 141 may be composed of a durable material exhibiting high impact resistance. Such a material may comprise a 3D printable material. Such a 3D printable material may comprise, for example, a polymer material. Embodiments, however, are not limited thereto, and thus, this disclosure contemplates forming the cover member body 141 using any suitable material that optimizes the performance of the example portable backpack vacuum 100 in a manner that falls within the spirit and scope of the principles of this disclosure.
As illustrated in
The lower housing body 121 is detachably connected via one or more lower latch members 117 to the upper housing 110 to enclose the interior space 122. When the example portable backpack vacuum 100 is not in use (e.g., after a cleaning sequence has been conducted), a user seeking to empty the interior space 122 of its contents, a user may selectively detach the lower housing body 121 from the upper housing body 111 by rotating the one or more lower latch members 117. As illustrated in
As illustrated in
The harness member 130 also includes a waist support member 132 that, when in operative use, is to extend around the waist region of the user in a manner that facilitates at least partial support of the portable backpack vacuum 100. One or more strap members 135 are operable to connect the shoulder support members 131 to the waist support member 132. By virtue of the structural connection between the waist support member 132 and the upper housing body 111, the waist support member 132 defines a load path for loads induced when the portable backpack vacuum 100 is worn by the user. Moreover, when the user is not wearing the portable backpack vacuum 100, the structural connection facilitates the pivoting of the waist support member 132 to the stowed position.
The waist support member 132 is connected to the upper housing body 111 at the second connection interface 118 via the one or more connection members 133, 134. In particular, the connection via the one or more connection members 133, 134 facilitates rotation of the waist support member 132 between a deployed position and a stowed position. Rotation to the stowed position may occur, for example, when the lower housing 121 is detachably removed from its connection with the upper housing 111, and the user places the portable backpack vacuum 100 on a support surface to cause engagement of the waist support member 132 with a support surface. Such rotation by the waist support member 132 to a stowed position facilitates the support of the upper housing body 111 on a support surface at the peripheral bottom edge(s) 119. In this way, the portable backpack vacuum 100 may stand level on the support surface. The waist support member 132, during translation from the deployed position to the stowed position, moves between approximately 0 degrees to approximately 90 degrees relative to the support surface.
The one or more connection members are operable to pivotably connect the waist support member 132 of the harness member 130 at the second connection interface 118 of the upper housing 110 in a manner that facilitates rotation of the waist support member 132 between the deployed position and the stowed position.
In the illustrated example embodiment of
Alternatively, the one or more connection members may comprise a hinge connector member 134 operable to facilitate rotation of the waist support member 132 relative to the upper housing 110 to the stowed position by engagement of the waist support member 132 with a support surface. The hinge connector member 134 may include one or more spring connector members operable to bias the waist support member 132 towards the stowed position after engagement of the waist support member 132 with the support surface. In one example embodiment, the hinge connector member 134 may comprise a 90-degree self-locking folding hinge. The hinge connector member 134 may be fabricated using a flexible material. Such a material may include, but is not limited to a polymer, a metal, a composite, or any combination thereof. Embodiments, however, are not limited thereto, and thus, this disclosure contemplates fabricating the hinge connector member 134 using any suitable material that optimizes the performance of the example portable backpack vacuum 100 in a manner that falls within the spirit and scope of the principles of this disclosure.
Alternatively, the one or more connection members may comprise a rotating joint member to connect the waist support member 132 to the upper housing 110. The rotating joint member may rotate to facilitate movement of the waist support member 132 to the stowed position by engagement of the waist support member 132 with a support surface.
