[0020] Before any embodiments of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways.

[0021] FIGS. 1-11 illustrate a battery-powered fan 10 including a fan base 14, an adjustment mechanism 18, a clamping mechanism 22, and a fan unit 26. The illustrated battery-powered fan 10 is coupled to a battery 30. The fan base 14 includes a first portion coupled to the battery 30 and a second portion coupled to the adjustment mechanism 18.

[0022] With reference to FIG. 5, the first portion of the fan base 14 includes a battery mounting portion having a first electrical contact 32. The battery 30 includes a second electrical contact 33 configured to electrically connect with the first electrical contact 32 while the battery 30 is coupled to the fan base 14.

[0023] As shown in FIGS. 1 and 3, the first portion of the fan base 14 also includes a speed control knob 34. The speed control knob 34 includes multiple ON positions of varying speed and an OFF position. While the speed control knob 34 is in one of the ON positions, the speed control knob 34 completes the electrical circuit between the battery 30 and the fan unit 26. While the speed control knob 34 is in the OFF position, the speed control knob 34 opens the circuit between the battery 30 and the fan unit 26.

[0024] With reference to FIG. 6, the first portion of the fan base 14 also includes a protruding component 36 defining an aperture. The protruding component 36 is configured to receive a lanyard or other rope like element through the aperture. If a user is operating the battery-powered fan 10 at a location spaced a set distance above the ground surface, a lanyard or other rope like element extending through the protruding component 36 to couple the battery-powered fan 10 to a structural component. In the event that the battery-powered fan 10 is bumped or otherwise becomes detached from a structural component, the lanyard or other rope like element will inhibit the battery-powered fan 10 from falling to the ground surface.

[0025] The second portion of the fan base 14 includes a first arm 38, a second arm 42, and a middle portion 46 between the first arm 38 and the second arm 42. The first arm 38 is coupled to the first portion of the fan base 14 and extends away from the first portion. The middle portion 46 includes a first end coupled to the first arm 38 and a second end coupled to the second arm 42. With reference to FIG. 4, the first arm 38 extends diagonally with respect to axis A, and the second arm 42 extends diagonally with respect to axis A. The middle portion 46 is positioned entirely offset from axis A.

[0026] As shown most clearly in FIGS. 1, 5 and 9, the adjustment mechanism 18 includes a U-shaped bar having a first end 50 coupled to the first arm 38 of the fan base 14, a second end 52 spaced apart from the first arm 38 and coupled to the second arm 42 of the fan base 14, and a middle portion 54 positioned between the first end 50 and the second end 52. The first end 50 includes a polygonal exterior shape and is coupled to the first arm 38 of the fan base 14 for rotation with respect to the fan base 14. The second end 52 includes a polygonal exterior shape that corresponds to the shape of the first end 50. The second end 52 is coupled to the second arm 42 of the fan base 14 for rotation with respect to the fan base 14. The first end 50 and the second end 52 project in a first direction, and the middle portion 46 projects in a second direction, opposite the first direction.

[0027] In some embodiments, an end cap 56 retains the second end 52 of the adjustment mechanism 18 on the second arm 42. The end cap 56 is connected to the second arm 42 and the second end 52 of the adjustment mechanism 18 is permitted to pivot with respect to the second arm 42 and the end cap 56.

[0028] The adjustment mechanism 18 is rotatable with respect to the fan base 14 about axis A (see FIGS. 4, 6 and 7). The adjustment mechanism 18 is coupled to the fan base 14 by a friction fit, such that the rotational position of the adjustment mechanism 18 is retained either primarily, or exclusively, by friction. In some embodiments, one or more detents or locking mechanisms are utilized to retain the adjustment mechanism 18 in the desired position. In some embodiments, the adjustment mechanism 18 is permitted to pivot about axis A within a range of about 250 degrees with respect to the fan base 14.

[0029] The clamping mechanism 22 includes a moveable clamping portion 58 and a fixed clamping portion 62. The moveable clamping portion 58 includes a moveable platform 66 having a lip 70 and an actuator 74. The illustrated moveable platform 66 is positioned within a recess in the middle portion 46 of the fan base 14. The lip 70 is configured to enhance the engagement between the clamping mechanism 22 and a structural member.

[0030] The illustrated actuator 74 includes an actuator knob 76, a threaded shaft 78 and a cam mechanism 80. The actuator knob 76 is coupled to the threaded shaft 78 to cause rotation of the threaded shaft 78 in response to rotation of the actuator knob 76. The cam mechanism 80 is positioned within the middle portion 46 and the threaded shaft 78 extends through the cam mechanism 80 and into the moveable platform 66. The cam mechanism 80 permits the threaded shaft 78 to move axially through the middle portion 46 and permits the threaded shaft 78 to rotate with respect to the middle portion 46. In some embodiments, the cam mechanism 80 can be similar to the mechanism described in U.S. Patent No. 12,085,415.

[0031] The actuator 74 causes linear movement of the moveable platform 66 in the direction of arrow 84 (see FIG. 2). To engage a structural component with the clamping mechanism 22, the user presses against the actuator knob 76 to cause rapid linear movement of the moveable platform 66 in the direction of arrow 84. Then, the user rotates the actuator knob 76 to cause slow linear movement, or precise adjustment, of the moveable platform 66 in the direction of arrow 84. The axial movement allows the moveable platform 66 to be positioned near the desired position and then the rotational movement allows the moveable platform 66 to be pressed into engagement with the component to which the clamping mechanism 22 is mounted. Conversely, to disengage the clamping mechanism 22 from a structural component, the user rotates the actuator knob 76 to slowly withdraw the moveable platform 66 in the direction of arrow 86. Then, the user moves the actuator knob 76 axially to quickly withdraw the moveable platform 66, to fully disengage the clamping mechanism 22 from the structural component. In other embodiments, other actuator configurations can be utilized.

[0032] With reference to FIGS. 6 and 7, the fixed clamping portion 62 is generally C-shaped and includes the middle portion 46 of the fan base 14, a first fixed portion 88 and a second fixed portion 90. The middle portion 46 is coupled to the adjustment mechanism 18 and receives the moveable platform 66 and the actuator 74. The first fixed portion 88 protrudes away from the middle portion 46 in the direction of arrow 84. The length of the first fixed portion 88 is sufficient to receive one of a variety of structural members, such as scissor lift rails, pipes, studs, rafters, etc. The second fixed portion 92 extends generally parallel to the middle portion 46 and the moveable platform 66.

[0033] The junction between the middle portion 46 and the first fixed portion 88 includes a bevel 96 configured to urge the structural member against the lip 70. The second fixed portion 92 includes an arcuate recess 100 configured to receive a portion of a round structural member. The third fixed portion 94 also includes a planar portion 102 configured to engage a flat portion of a planar structural component.

[0034] With reference to FIGS. 9 and 10, the fan unit 26 includes a rotating blade 106, a fan housing 110, a connecting portion 114 and a handle 118. The battery 30 provides electrical current (through first and second electrical contacts 32, 33) to the fan unit 26 to cause rotation of the rotating blade 106 while the speed control knob 34 is in any of the ON positions. The rotating blade 106 is powered by the battery 30 at a speed determined by the speed control knob 34. In some instances, the speed control knob 34 in in the OFF position, and the rotating blade 106 remains stationary. The speed control knob 34 can cause rotation of the rotating blade 106 within a range of speeds while an electrical circuit between the battery 30 and the fan unit 26 is complete. The speed of rotation of the rotating blade 106 is variable within a range of speeds based upon the rotational speed setting of the speed control knob 34.

[0035] The fan housing 110 surrounds the rotating blade 106 and includes the connecting portion 114 at a first end of the fan housing 110 and the handle 118 at a second end of the fan housing 110, opposite the first end. The connecting portion 114 is coupled to the middle portion 46 of the adjustment mechanism 18 to permit rotation of the fan unit 26 about axis B. The fan unit 26 has a single connection point with the adjustment mechanism 18.

[0036] The connecting portion 114 is coupled to the adjustment mechanism 18 by a friction fit, such that the rotational position of the fan unit 26 with respect to the adjustment mechanism 18 is retained either primarily, or exclusively, by friction. In some embodiments, one or more detents or locking mechanisms are utilized to retain the fan unit 26 in the desired rotational position. In some embodiments, the fan unit 26 is permitted to rotate about axis B both clockwise and counterclockwise to any rotational position with respect to the adjustment mechanism 18 (i.e. within a range of about 360 degrees). In some embodiments, one or more hard stops is included to limit rotation past a set rotational position in one or both directions.

[0037] The rotating blade 106 rotates about an axis C. Axis C is perpendicular to axis A and to axis B. Axis A is also perpendicular to axis B. In some embodiments, axis C is non-parallel to, but not necessarily perpendicular to axis A and to axis B.

[0038] The battery 30 includes the second electrical contact 33 configured to form an electrical connection with the first electrical contact 32 while the battery 30 is coupled to the fan base 14. The battery 30 can be removed and recharged. The battery 30 can be any suitable battery within a range of sizes and wattages sufficient to provide power to the rotating blade 106.

[0039] With reference to FIGS. 1 and 2, gripping elements 122, 123 and 124 are included on the fan base 14, and gripping element 125 is positioned on the clamping mechanism 22. The gripping elements 122, 123, 124, 125 are configured to increase friction with a surface when positioned on the surface to thereby inhibit the battery-powered fan 10 from slipping along the surface while supported on the surface and while disengaged from the structural component. While the fan base 14 and the clamping mechanism 22 are positioned on a surface, the fan unit 26 is positioned above the clamping mechanism 22. Other sizes, shapes and locations of gripping elements can be utilized in other embodiments. The fan base 14 and the clamping mechanism 22 are shaped to receive multiple different sizes of battery 30 such that the battery 30 is adjacent a surface or spaced above a surface while the gripping elements 122, 123, 124, 125 engage the surface.

[0040] In operation, the battery-powered fan 10 can be mounted to a structural member, such as a scissor lift rail, a pipe, a stud or a rafter via the clamping mechanism 22. The user will position the clamping mechanism 22 such that the structural member is positioned between the middle portion 46 and the second fixed portion 92, preferably abutting the first fixed portion 88. The user will then push the actuator knob 76 axially until the moveable platform 66 abuts the structural member. Then, the user will rotate the actuator knob 76 to further press the moveable platform 66 against the structural member. In this orientation, the fan unit 26 is suspended below the adjustment mechanism 18 and the clamping mechanism 22, such as shown in FIGS. 7-10. Then, the user pivots the fan unit 26 about axis A and about axis B to the desired orientation. Friction between the fan base 14, the adjustment mechanism 18, the clamping mechanism 22 and the fan unit 26 retains the fan unit 26 in the desired orientation. The steps are reversed to detach the battery-powered fan 10 from the structural member.

[0041] A lanyard or other rope like element can be inserted through the protruding component 36 and connected to the structural component or other nearby component to further secure the battery-powered fan 10 to the structural component or other nearby component when used above a set height. When not in use, or if desired for operation, the battery-powered fan 10 can rest on a surface such that the gripping elements 122, 123, 124, 125 engage the surface.
