The axle 26 has two apertures 31 thereon to allow a wire or the like to enter and exit the interior portion of the axle 26. Alternative constructions may have additional apertures to allow for additional entry and exit points into the axle. Another alternative construction may include caps placed in each end of the axle 26 near the first and second recesses 28, 30 to seal the ends of the axle 26. Both ends of the axle 26 are received in the base assembly 12 such that that the axle 26 is coupled to the base assembly 12. The first and second recesses 28, 30 are sized to inhibit rotation of the axle 26 with respect to the base assembly 12. In some embodiments the axle 26 is coupled to the first and second recesses 28, 30 to inhibit rotation of the axle 26 with respect to the base assembly 12.
- the upper housing 22 includes a handle 32, a dirt chamber 34, a motor housing 33 and a yoke 36.
- a dirt opening (not shown) is disposed on the dirt chamber 34 to allow the dirty air hose 20 to be fluidly coupled to the dirt chamber 34.
- a motor 54 for driving a suction fan (not shown) is disposed in the motor housing 33.
- the yoke 36 is in the shape of an inverted “U", with the motor housing 33 being disposed at the base of the "U".
- the yoke includes an open interior portion 37 illustrated in Fig. 1.
- the yoke 36 includes a first opening 38 and a second opening 40 to allow the axle 26 to pass through the yoke 36.
- Bearings 42 are disposed in the first and second openings 38, 40.
- the bearings 42 are sized and configured to allow the axle 26 to pass through the bearings 42.
- the bearings 42 allow the upper housing 22 to rotate with respect to the axle 26 and the base assembly 12.
- the first wheel 14 and second wheel 16 are substantially similar. Both the first wheel 14 and the second wheel 16 have a width w of approximately .75 inches and a diameter d of 7.5 inches. Alternative embodiments may use a diameter d between 6.5 and 9 inches. Yet other alternative embodiments use a diameter d between 6.5 and 7.5 inches.
- the first and second wheels 14, 16 have openings 60, 62 disposed therein to allow the axle 26 to pass through the first and second wheels 14, 16.
- Bearings 39 are disposed in the openings 60, 62.
- the bearings 39 are sized and configured to allow the axle 26 to pass through the bearings 39.
- the bearings 39 allow the first wheel 14 and second wheel 16 to rotate with respect to the axle 26.
- the first wheel 14 and second wheel 16 may rotate independently of one another.
- the wheel separation distance D is defined as the distance between the centerline of the first wheel 14 and the centerline of the second wheel 16.
- the first wheel 14 and the second wheel 16 have a wheel separation distance D of approximately 6 inches, but other embodiments envision placing the first wheel 14 and the second wheel 16 such that the wheel separation distance D is between 4.5 and 7.5 inches. In other embodiments the wheel separation distance D is 5.5 to 6 inches.
- the ratio of first wheel 14 or second wheel 16 diameter d to wheel separation distance D to is important because the proper ratio assists in allowing the vacuum cleaner 10 to be easily maneuvered in tight spaces and assists in allowing the vacuum cleaner to have a zero turn radius.
- the ratio of wheel diameter d to wheel separation distance D to is 1.25.
- Alternative embodiments contemplate the ratio of wheel diameter d to wheel separation distance D being between .85 and 2.
- Yet other embodiments contemplate the ratio of wheel diameter d to wheel separation distance D being between 1.15 and 1.35.
- the zero turn radius allows the vacuum cleaner 10 to rotate about a central axis of the upper housing 22 while the first wheel 14 and second wheel 16 have minimal or no skid or slip with respect to a surface to be vacuumed.
- Prior art vacuum cleaners are not as easily maneuverable and do not have such a zero turn radius, at least in part due to their ratio of wheel diameter to wheel separation distance. It has been found that a vacuum cleaner 10 having a zero turn radius is easier to operate and use, as compared to vacuum cleaners not having a zero turn radius, thus leading to greater ease and efficiency in vacuuming.
- the cord reel assembly 18, illustrated in section view in Fig. 4, includes a reel housing 44, a drum 46, a torsion spring 56, a brake (not shown), a brake release lever 47 (seen in Fig. 3), an electrical cord 48, a pair of commutator rings (not shown), and an electrical lead 50.
- the brake serves to inhibit drum 46 from rotating in at least one direction with respect to the reel housing 44.
- the reel housing 44 is cylindrical in shape and is hollow so that other elements of the cord reel assembly 18 may reside therein.
- the reel housing 44 has an opening 45 disposed thereon (seen in Fig. 3) to allow a portion of the electrical cord 48 to exit the reel housing 44.
- the drum 46 is disposed within the reel housing 44 and is able to rotate with respect to the reel housing 44.
- the reel housing 44 has an aperture 35 in the interior portion which is aligned with the aperture 31 of the axle 26 to allow the electrical lead 50 to exit the reel housing 44 and enter the axle 26.
- the electrical cord 48 is configured to provide electrical power to the vacuum cleaner 10.
- the torsion spring 56 is disposed next to the drum 46 and is coupled to the drum 46 and the reel housing 44.
- the brake is coupled to the drum 46 and the reel housing 44.
- the brake is coupled to the brake release lever 47 such that when the brake release lever 47 is pressed, the brake is released.
- the brake release lever 47 is sized and configured such that it is easily operated with the user's foot.
- the reel housing 44 is coupled to the axle 26 by a key
- the key 49 is an integral part of the reel housing 44, and the key 49 resides in a slot in the axle 26. In another construction, the key not an integral part of the reel housing 44. Alternative constructions may couple the reel housing 44 to the axle 26 with a friction fit, an adhesive, etc.
- the electrical cord 48 may be substantially wound around the drum 46, but may be partially pulled out of the reel housing 44.
- the electrical cord 48 includes a plug 52 which, due to the size and configuration of the opening 45, is inhibited from entering the interior portion of the reel housing 44.
- the electrical cord 48 is electrically coupled to the pair of commutator rings.
- the commutator rings are electrically coupled to the electrical lead
- the electrical lead 50 is electrically connected to the motor 54. As can be seen in Fig. 4, the electrical lead 50 exits the reel housing 44 through the aperture 35 and enters the interior portion of the axle 26 through the aperture 31. The electrical lead 50 then exits the interior portion of the axle 26 between the first wheel 14 and the yoke 36. The electrical lead 50 then enters the motor housing 33 where it is electrically connected to the motor 54. Thus when the electrical cord 48 is electrically connected to an electrical outlet, the motor 54 is able to receive electrical power. In an alternative embodiment the electrical lead 50 may also be electrically connected to another motor, a light, or some other accessory that requires electrical power.
- the electrical cord 48 In a stored position, the electrical cord 48 is substantially disposed in the interior of the reel housing 44, the electrical cord 48 being wrapped around the axle 26 as shown in Fig. 4.
- the drum 46 rotates with respect to the reel housing 44.
- the brake allows the drum 46 to rotate with respect to the reel housing 44, by means of a ratchet mechanism for example, in only one direction when the brake is applied.
- the brake release lever 47 When the user wishes to wind the electrical cord 48 into the reel housing 44, the user pushes the brake release lever 47. When the brake release lever 47 is pressed, the brake is released which allows the drum 46 to rotate in either direction.
- the torsion spring 56 exerts a force on the drum 46 to turn the drum 46 in a direction that winds the electrical cord 48 back around the drum 46.
- An alternative embodiment, illustrated in Fig. 5, of the vacuum cleaner 10 includes an independent drive motor 58 for the first wheel 14 and a second independent drive motor 58 for the second wheel 16.
- the independent drive motors 58 may take the form of pancake motors placed next to the wheels 14, 16. Thus each wheel 14, 16 can be driven independently of the other wheel 14, 16.
- drive motors can be placed between the wheels in place of the cord reel assembly 18.
- a single drive motor with a transmission for each wheel can be placed between the wheels in place of the cord reel assembly 18.
- each of the wheels can be driven in forward and reverse directions allowing for zero radius turns.
- the independent drive motors 58 are electrically connected to the electrical cord 48 in a similar fashion as has been described with regard to the motor 54.
- the independent drive motors 58 can be used with the cord reel assembly 18, the independent drive motors 58 being disposed proximate to the cord reel assembly 18.
- Yet another embodiment of the vacuum cleaner 10 has a filter housing and a filter, such as a HEP A filter, disposed between the wheels in place of the cord reel assembly 18.
- a filter housing and a filter such as a HEP A filter
- conduits are coupled to the filter housing to deliver an air stream to and away from the filter.
- a filter housing and filter are used in combination with the cord reel assembly 18, the filter housing and filter being disposed in an interior portion of the drum 44.
- axle 26 In the embodiment illustrated in Figs. 1-4, only one axle 26 is used. However, other embodiments contemplate using multiple axles. Some constructions which are contemplated include an axle for the first wheel 14, an axle for the second wheel 16, an axle for the cord reel assembly 18, an axle for the yoke 36, and an axle for the base assembly 12, or any combination of these axles. In one construction, at least one of the axles may be offset from the other axles.
- first wheel 14 and the second wheel 16 in the interior of the yoke 36 facilitates stable turns and allows the user to easily maneuver the vacuum cleaner 10 in small areas.
- the connection of the yoke 36 to the axle 26 also facilitates stable turns of the vacuum cleaner 10 and assists in allowing the user to easily maneuver the vacuum cleaner 10 in small areas.
- the location of the first wheel 14 and second wheel 16 with respect to the yoke, and the connection of the yoke 36 to the axle 26 allows the vacuum cleaner 10 to have a zero turn radius such that the vacuum cleaner 10 rotates about a central axis of the upper housing 22 while the first wheel 14 and second wheel 16 have minimal or no skid or slip with respect to a surface to be vacuumed.
- Prior art vacuum cleaners are not as easily maneuverable and do not have such a zero turn radius due to at least one of the location of their wheels and the connection of an axle to the housing instead of a yoke.
- the ratio of suction nozzle 24 width N to wheel separation distance D aids in the stability of the vacuum cleaner 10 and assists in allowing the vacuum cleaner 10 in maneuvering in tight spaces.
- the suction nozzle 24 width N to wheel separation distance D ratio is 2.3.
- other embodiments may have a suction nozzle 24 width N to wheel separation distance D ratio of between 2.0 and 2.5.
- Even other embodiments may have a suction nozzle 24 width N to wheel separation distance D ratio of between 1.6 and 3.5.
- the diameter d of the first wheel 14 and second wheel 16 aids in the stability of the vacuum cleaner 10 and assists in allowing the vacuum cleaner 10 in maneuvering in tight spaces.
- the invention provides, among other things, a vacuum cleaner 10.
- a vacuum cleaner 10 provides, among other things, a vacuum cleaner 10.
