Definitions

  • the present invention relates to vacuum cleaners and, more particularly, to upright vacuum cleaners.
  • Upright vacuum cleaners are typically used to clean floor surfaces, such as carpeting. These types of vacuum cleaners, however, can be difficult to maneuver and operate in relatively confined areas. In addition, it is sometimes desirable to clean elevated surfaces, such as drapes, furniture, or steps, with a vacuum cleaner.
  • the invention provides a vacuum cleaner including a base having a foot with a suction nozzle and a handle assembly removably coupled to the foot.
  • the handle assembly is movable between a first position, in which the handle assembly is connected to the foot, and a second position, in which the handle assembly is disconnected to the foot.
  • the vacuum cleaner also includes a canister assembly supported by the base.
  • the canister assembly is removable from the base.
  • the vacuum cleaner further includes a latch supported by one of the foot and the handle assembly. The latch is engageable with the other of the foot and the handle assembly to selectively secure the handle assembly to the foot. The latch is inaccessible when the canister assembly is supported by the base.
  • the invention provides a vacuum cleaner including a base having a foot with a suction nozzle and a handle assembly removably coupled to the foot.

  • the canister assembly 36 filters or otherwise cleans the airflow, the cleaned airflow is directed out of the vacuum cleaner 20 and back into the environment.
  • FIG. 1A-4 the illustrated vacuum cleaner 20 is operable in a variety of different cleaning modes.
  • FIGs. 1A and IB illustrate the vacuum cleaner 20 in a standard mode. In this mode, the handle assembly 32 is connected to the foot 28, and the canister assembly 36 is supported by the base 24.

  • Such an arrangement inhibits the canister assembly 36 from sliding, rocking, shifting, or otherwise moving side-to-side relative to the handle assembly 32 when supported by the mounting post 224.
  • such an arrangement helps position the canister assembly 36 on the base 24 so that the latch 228 on the canister assembly 36 properly aligns with a corresponding structure of the handle assembly 32.
  • the latch 228 is supported by the canister assembly 36.
  • the illustrated latch 228, or engagement member, is supported at an upper end of the canister assembly 36 opposite from the suction motor 176.
  • the latch 228 is operable to engage a portion of the handle assembly 32 to releasably secure the canister assembly 36 to the handle assembly 32.
  • the latch 228 is located on the canister assembly 36 between the first and second ends 84, 88 of the extension tube 44.
  • the latch 228 is located between the grip 48 of the handle assembly 32 and the mounting post 224. With the mounting post 224, the latch 228 provides a three-point connection (two points on the mounting post 224 and one point on the latch 228) for connecting the canister assembly 36 to the handle assembly 32 and the foot 28.
  • the latch 228 includes a manual actuator 268, a hook 272, and a biasing member 276 (Figs. 14 and 15).
  • the manual actuator 268 extends outwardly from the body 168 of the canister assembly 36 to be actuated (e.g., depressed) by a user.
  • the hook 272 is configured to engage a flange 280 of the handle assembly 32 to secure the latch 228 to the handle assembly 32.
  • the illustrated hook 272 is integrally formed as a single piece with the actuator 268. In other embodiments, the actuator 268 and the hook 272 may be separate elements that are coupled together. Additionally or alternatively, in some embodiments, the latch 228 may be supported by the handle assembly 32, and the flange 280 may be formed on the canister assembly 36.
  • the biasing member 276 is positioned between the actuator 268 and an inner surface 284 of the body 168.
  • the biasing member 276 biases the hook 272 into engagement with the flange 280.
  • the biasing member 276 is a coil spring that surrounds a boss 288 of the actuator 268. In other embodiments, other suitable biasing members may also or alternatively be employed.
  • Fig. 14 illustrates the latch 228 in an engaged position.
  • the manual actuator 268 is fully extended from the body 168 of the canister assembly 36, and the hook 272 extends behind the flange 280 to engage the flange 280 and secure the canister assembly 36 to the handle assembly 32.
  • the hook 272 moves (e.g., slides) away from the flange 280. Once the hook 272 clears the flange 280, the canister assembly 36 is released from the handle assembly 32. The canister assembly 36 can then be removed from the base 24.
  • the canister assembly 36 is removable from the handle assembly 32 and the foot 28 using a rocking or pivoting motion and a lifting motion.
  • the canister assembly 36 is supported by the mounting post 224 and secured to the handle assembly 32 by the latch 228.
  • the latch 228 is actuated to disengage the flange 280
  • the canister assembly 36 can be pivoted about the mounting post 224 relative to the handle assembly 32 and the foot 28.
  • the canister assembly 36 is pivotable in a first direction A (counterclockwise in Fig. 6) away from the handle assembly 32 when the latch 228 disengages the flange 280 on the handle assembly 32.
  • the canister assembly 36 (which includes the suction motor 176, the separator unit 180, and the dirt collection unit 184) can be lifted as a single assembly off of the mounting post 224 to operate the vacuum cleaner 20 in the second, third, or fourth cleaning modes, as shown in Figs. 2-4. Separating the canister assembly 36 from the handle assembly 32 and the foot 28 also allows the foot pedal 132 (Fig. 7) to be actuated to disconnect the handle assembly 32 from the foot 28.
  • the canister assembly 36 can be reconnected to the handle assembly 32 and the foot 28 using a substantially opposite set of motions.
  • the groove 240 (Fig. 1 1) in the canister assembly 36 is generally aligned with the mounting post 224. Once aligned, the canister assembly 36 is lowered onto the mounting post 224 such that the mounting post 224 is received in the groove 240 and the canister assembly 36 is supported by the foot 28.
  • the canister assembly 36 is then pivoted in a second direction (clockwise in Fig. 6) opposite the first direction A and toward the handle assembly 32. As the canister assembly 36 is pivoted toward the handle assembly 32, the hook 272 of the latch 228 engages the flange 280 of the handle assembly 32.
  • the hook 272 is configured to automatically move against the bias of the biasing member 276 and out of the way of the flange 280 as the canister assembly 36 is being connected to the handle assembly 32 without requiring a user to actuate the manual actuator 268. Once the hook 272 clears the flange 280, the biasing member 276 biases the hook 272 back into engagement behind the flange 280 to secure the canister assembly 36 to the handle assembly 32. Biasing the latch 228 into engagement with the flange 280 also provides an audible "click" to notify the user that the canister assembly 36 is properly connected to the handle assembly 32.
  • the relative locations of the mounting post 224 and the latch 228 may be reversed.
  • the latch 228 may be located adjacent the first end 84 of the handle assembly 32, and the mounting post 224 may be located between the grip 48 of the handle assembly 32 and the latch 228.
  • the canister assembly 36 may still be removed from and reconnected to the handle assembly 32 and the foot 17 in a similar manner as described above.
  • a bottom portion of the canister assembly 36 (rather than an upper portion) may be pivoted toward and away from the handle assembly 32 when the canister assembly 36 is installed on and removed from the base 24.

Abstract

L'invention concerne un aspirateur comprenant une base comportant une tête dotée d'une buse d'aspiration et un ensemble manche accouplé de manière amovible à la tête. L'ensemble manche est mobile entre une première position, dans laquelle l'ensemble manche est raccordé à la tête, et une seconde position, dans laquelle l'ensemble manche est détaché de la tête. L'aspirateur comprend également un ensemble réservoir supporté par la base. L'ensemble réservoir peut être séparé de la base. L'aspirateur comprend en outre un dispositif de verrouillage supporté par l'un de la tête et de l'ensemble manche. Le dispositif de verrouillage peut être mis en prise avec l'autre de la tête et de l'ensemble manche afin de fixer de façon sélective l'ensemble manche à la tête. Le dispositif de verrouillage est inaccessible lorsque l'ensemble réservoir est placé sur la base.
