DETAILED DESCRIPTION OF THE INVENTION

Referring now specifically to the drawings, an improved compressed air device is illustrated in FIG. 1 and is shown generally at reference numeral 10. The device 10 includes a base 12, a motor 14, and at least one compressor 16, as shown in FIGS. 1-6. Preferably, the device 10 will include two compressors 16 that are mounted to the base 12. The base 12 may have a plurality of sides. As illustrated in FIG. 1, the base has a first side 18, a second side 20, and a third side 22. Each side (18, 20, and 22) has a top portion and a bottom portion. The top portion of the sides (18, 20, and 22) is the exposed portion or the portion that is more easily accessible to a user when the device 10 is in the upright position. By way of example, the motor 14 is positioned on the top portion of the first side 18, as illustrated in FIG. 1 and the compressors 16 are positioned on the top portion of the second side 20 and third side 22. The bottom portion of the sides (18, 20, and 22) is the portion opposite the top portion.

The base 12 may have any form, but as illustrated in FIG. 1, the base has a substantially triangular form. The term substantially triangular form means that the base includes three primary sides that may be adjacent to one another. In other words, the sides may intersect. The term substantially triangular form may also mean that the three primary sides do not intersect, but the planes of the sides intersect at a point or are an asymptote.

The sides (18, 20, and 22) of the base 12 are in a spaced apart relationship forming a void 24 within. As illustrated in FIG. 1, the motor 14 is positioned within the void 24 and is engaged to the top portion of the first side 18. The motor is fastened to the top portion of the first side by a bolt, screw, weld, or the like.

The second side 20 of the base 12 includes at least one pair of slots 26. The third side 22 of the base 12 includes at least one pair of slots 26. Preferably and as illustrated in FIG. 8, the second side 20 and third side 22 of the base 12 includes two pairs of slots 26 disposed on each side (20, 22). Each compressor 16 preferably contains a fastener that extends from the bottom of the compressor 16. The fastener may be a belt, screw, threaded extension or the like. In the examples, a threaded extension is utilized as a fastener and extends from the compressor 16 and is inserted into the slots 26. By way of example only and as shown in the figures, the compressor 16 includes four (4) threaded extensions or bolts that extend downward and are inserted into the slots 26. Each bolt contains a threaded end for receiving a correspondingly threaded nut. The threaded extension also receives a correspondingly threaded nut.

The compressors 16 are slidingly engaged to the top portion of the second side 20 and the top portion of the third side 22 of the base 12 with the use of an adjusting plate 28. As illustrated in FIGS. 8 and 10, the adjusting plate 28 comprises a face 30, a lip 32, and a rib 34. The face 30 of the adjusting plate 28 contains at least a pair of bores 36 for receiving the fastener that extends from the bottom of the compressor 16. Preferably, the face 30 of the adjusting plate 28 contains two pairs of bores 36 for receiving the fastener that extends from the bottom of the compressor 16. The lip 32 is positioned about 90° with respect to the face 30. The lip 32 contains at least one threaded bore 38. Preferably, the lip 32 contains two threaded bores 38. The rib 34 of the adjusting plate 28 is optional, but can be added to provide strength and stability to the adjusting plate 28.

During use, an adjusting plate 28 is positioned on the bottom side of the second side 20 of the base 12, and an adjusting plate 28 is positioned on the bottom of the third side 22 of the base 12, as shown in FIG. 8. The bores 36 of the adjusting plate 28 are aligned with the slots 26 of the second side 20 and third side 22 of the base 12. The fastener disposed on the bottom of the compressor 16 is received within the slot 26 of the sides (20, 22) and the bore 36 of the adjusting plate 28. As set forth above and by way of example only, the fastener is a threaded fastener engaged to the bottom side of the compressor 16 and when the threaded fastener is inserted through the slot 26 and bore 36; a nut may be selectively secured to the threaded fastener, thus allowing the compressor 16 to be selectively secured or engaged to the adjusting plate 28.

The second side 20 and third side 22 of the base 12 contain a hole 40 positioned in close proximity to the area where the second side 20 and third side 22 are engaged, as shown in FIG. 7. A threaded fastener 42 is received within the hole 40. The threaded fastener may be a bolt, screw, or the like. As illustrated in FIGS. 3-8, the threaded fastener 42 is designed to be inserted into the threaded bore 38 positioned on the lip 32 of the adjusting plate 28. The threaded fastener 42 received within the hole 40 positioned on the second side 20 is received within the threaded bore 38 of an adjusting plate 28 positioned beneath the bottom side of the third side 22. Likewise, the threaded fastener 42 received within the hole 40 positioned on the third side 22 is received within the threaded bore 38 of an adjusting plate 28 positioned beneath the bottom side of the second side 20.

During use, the threaded fastener 42 is rotated, causing the adjusting plate 28 to translate or adjust along the side (20, 22) of the base 12. Preferably, the device 10 will include a pair of threaded fasteners 42 that are received within a pair of threaded bores 38 disposed on the lip 32 of the adjusting plate 28. Therefore, when both of the threaded fasteners 42 are rotated, the adjusting plate 28 translates or adjusts along the side (20, 22) of the base 12, as illustrated in FIGS. 4 and 5. It should be noted that the term translates or adjust means that the adjusting plate 28 moves relative to the side (20, 22). By way of example only, as shown in FIG. 5, the adjusting plate 28 moves a distance “d”, causing the center point of the compressor to move a distance “x” from the motor 14. The side (20, 22) is stationary and the adjusting plate 28 moves relative to the side (20, 22). In one embodiment, as the threaded fasteners 42 are rotated in the clockwise position, the adjusting plate 28 moves upwards or towards the juncture where the second side 20 and third side 22 are engaged. As the threaded fasteners 42 are rotated counterclockwise, the adjusting plate 28 moves downward or toward the first side 18. Since the compressors 16 are engaged to the adjusting plates 28, the position of the compressors 16 are adjusted by the movement of the adjusting plate 28.

As illustrated in FIG. 6, the motor 14 includes a drive wheel 44 and each compressor 16 includes a slave wheel 46. A belt 48, as shown in FIGS. 2 and 3, is positioned on the drive wheel 44 and the slave wheel 46, allowing the motor 14 to supply rotational energy to the compressor 16 for operating the compressor 16. For the device 10 to run efficiently, economically, and smoothly, the belts 48 must contain the optimum amount of tension. During the rotation of the threaded fasteners 42, the compressors 16 are adjusted for providing the optimum amount of tension in the belts 48, as illustrated in FIGS. 4 and 5. Additionally, a protection shield may be positioned over the drive wheel 44, slave wheel 46, and the belts 48 to protect the safety of user of the device from getting limbs, hair, or clothing tangled with the gears (44, 46) and belts 48. The protection shield also reduces the amount of dirt or debris that enters the wheel (44, 46) and belts 48.

As illustrated in FIG. 1, a mounting foot 52 may be engaged to the device 10 for selectively securing the device 10 to a structure. The mounting foot 52 may be selectively secured to the device 10 by fasteners, such as a bolt, and the mounting foot 52 may be selectively secured to the structure by a fastener, such as a bolt. As illustrated, the mounting foot 52 may be selectively secured to the first side 18, second side 20, or third side 22 of the base 12.

In another alternative embodiment of the present invention as shown in FIG. 10, the base 112 may have a generally trapezoidal shape. In other words, the base 112 may have four sides. The only difference between this embodiment and the embodiment described above is the fourth side 154. The motor may be positioned on the fourth side 154 or within the cavity.

Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples may perform similar functions and/or achieve like results.
