In some embodiments, referring to FIGS. 1-3, the air conduit assembly 21 may further include a swivel fitting 25 at the distal end 24 of the air conduit 22 to allow a hose (not shown) of a mounted air blower (not shown) to rotate on an axis at the distal end 24. Such rotation may be up to 360 degrees. It should be appreciated that other mechanisms, dimensions, and shapes may be employed. In some alternate examples, the conduit may be fitted to the housing 2 via a swivel fitting (not shown) comprising a swivel or ball-type joint within a corresponding aperture in the housing 2, to allow polyaxial movements of the air conduit 22 within the housing aperture to accommodate movement of the air blade tool 100 relative to the attached blower hose. In some such embodiments, the ball-type joint comprises a ball joint having a through channel for the flow of air and engageable within the air conduit 22 and within the housing aperture which has a corresponding ball shaped recess to thereby permit rotation at both junctions of the ball joint with each of the air conduit 22 and the housing 2.

Referring to FIG. 2, the bottom of the housing 2 forms a plane 7, and the plane 7 extends along a longitudinal axis 8. In some embodiments, referring to FIG. 8, the air conduit 22 extends from one end 34, 34′ of the housing 2 at its proximal end 23 along a first axis 26 at a first angle 27, and the first angle 27 is defined by the longitudinal axis 8 of the bottom plane 7 of the housing 2 and the first axis 26 of the air conduit 22. The air conduit 22 continues to extend to its distal end 24 along a second axis 28 at a second angle 29. The second angle 29 is defined by the longitudinal axis 8 and the second axis 28. The angles 27, 29 may range from about 0° to about 90°. In some embodiments, the angles 27, 29 may be the same. The angles 27, 29 are configured and function such that the hose (not shown) of the mounted air blower (not shown) does not directly contact the surface of a cleaning area, and the user of the air blade tool 100 is able to operate the tool 100 with one hand while in use. It should be appreciated that other mechanisms, shapes, dimensions, and sizes may be employed.

Referring to FIGS. 4 and 5, air supplied from an air blower (not shown) through the air conduit 22 forms air flow 20 inside the housing 2, blows out through openings 5 downward, and removes contaminants on the surface of a cleaning area. In some embodiments, referring to FIGS. 15-17, the housing 2 further includes a damper 19. The damper 19 is positioned within the housing 2 and is configured to be adjustably positionable to be disposed at a predetermined position. The damper 19 is configured such that the damper 19 can redirect the air flow 20 to one side, e.g., the left side openings 5 or right side openings 5, or both, depending on its 19 position. Then the air flow 20 inside the housing 2 may be redirected by the position of the damper 19 to predetermined openings 5 and blow out therethrough. For instance, if the damper 19 is disposed at the center, the air supplied from the air blower (not shown) will blow out through both sides of the openings 5. However, when the damper 19 is disposed to one side, e.g., the right side, such that the damper 19 operates directing the air flow 20 to the opposite side, the air blows out through the openings 5 disposed on the opposite side, e.g., the left side, and removes contaminants thereunder. When the blade 12 is used in concert with the air from the air blade tool 100 to clean the surface of a cleaning area, contaminants, such as greywater, on the surface will be directed by the air from the tool 100 and blade 12 to only one side opposite the blade 12, and the contaminants will not impinge on the other side, e.g., already cleaned areas. It should be appreciated that other mechanisms, shapes, dimensions, and sizes may be employed.

Referring to FIGS. 14-17, 22, and 23, in some embodiments, an actuator 30 can be used to actuate the damper 19 and control the position of the damper 19 inside the housing 2. An actuator 30 may be a switch 31 or a button 32. Referring to FIGS. 14-17, a switch 31 can be disposed at a predetermined position, e.g., the right side, and the damper 19 actuated by the switch 31 sweeps to a predetermined position, e.g., the right side, inside the housing 2 such that the damper 19 can direct air flow 20 to at least one opening 5, e.g., the left side openings 5. The switch 31 can also be disposed at the center, and the damper 19 actuated by the switch 31 sweeps to the center inside the housing 2 such that the damper 19 directs the air flow 20 to both side openings 5, e.g., the left and right side openings 5. The switch 31 can be locked at a predetermined position. Yet, in other embodiments, a button 32 may be used to actuate a damper 19 and control the position of the damper 19. The button 32 may be held in place until released in order to actuate the damper 19 and control the position of the damper 19 inside the housing 2. Alternatively, the button 32 may be toggled in order to actuate the damper 19 and control the position of the damper 19 inside the housing 2. It should be appreciated that other types of actuators 30 can be employed. It should be further appreciated that other mechanisms, shapes, dimensions, and sizes may be employed.

In use, according to the various embodiments, the air blade tool allows for methods of cleaning of surfaces and crevices, for example, the surfaces of cars after cleaning to allow for the removal of water from the surface without introduction of wipe marks and to avoid water spotting. Other uses include removal of particulates and air from surfaces, or from crevices, such as in window wells and other joints.

According to embodiments in which the blade assembly is replaceable, operation of the replaceable blade allows ready switching of blades of different types for different surfaces, or to replace spent blades. According to embodiments in which the air conduit assembly includes a swivel fitting either at the junction of the air conduit with the housing or at the distal end of the air conduit, the swivel ensures that the handle and blade positions remain true to the treated surface despite kinking or winding of a hose affixing the tool to a blower, with the further benefit of avoiding hand fatigue for the user and avoiding interference of the blower/hose with the arm or hand of the user, and with the further benefit of minimizing rubbing or other contact of the blower/hose with the treated surface. According to embodiments in which the tool includes a damper, the damper enables the user to select the direction of air flow to one side, or both sides of the bottom of the housing whereby selection of one side or the other prevents blow back of particulates and water toward a direction of the surface or crevice that has been cleaned or wiped of water.
