Figure 4a is a detailed rear elevational view with a housing cover removed to clearly show the release lever and lock when in the locked position; and Figure 4b is a view similar to Figure 4a but showing the release lever and lock in position to release the wand from the connector.
Reference will now be made in detail to the present preferred embodiment of the invention, an example of which is illustrated in the accompanying drawing.
Detailed Description of the Invention As illustrated in Figure 1, the present invention relates to an upright vacuum cleaner 10 including a housing comprising both a nozzle assembly 12 and a canister assembly 14. The canister assembly 14 is pivotally connected to the nozzle assembly 12. The upright vacuum cleaner 10 rides over the floor surface being cleaned on wheels 15 carried on the housing.
The nozzle assembly 12 includes a suction inlet 16. A rotary agitator 18 carried on the nozzle assembly 12 is mounted adjacent to or in the suction inlet 16. The rotary agitator 18 includes bristle tufts 20, brushes, wipers or the like to beat dirt and debris from the nap of an underlying 5 carpet being cleaned as the agitator is rotated at high speeds with respect to that carpet and the nozzle assembly 12.
The canister assembly 14 includes a dirt collection vessel 22 housed in a receiver or internal cavity 23. In the illustrated embodiment the dirt collection vessel 22 is a dust bag of permeable filter material adapted to entrap dirt and debris while allowing the passage of clean air through the bag. In an alternative embodiment the dirt collection vessel 22 may take the form of a dirt cup and filter combination. Such a dirt cup may or may not provide for cyclonic air flow. Further, the dirt cup may be equipped with a filter.
The canister assembly 14 also includes a telescopic handle and wand assembly generally designated by reference numera124. The telescopic handle and wand assembly 24 includes first and second telescopic wand sections 26, 28 connected together by a locking coupler 30 similar to the structure shown and described in U.S. Patent 6,148,474 to Ohara et al. and owned by the assignee of the present invention. A control hand grip 32, including a multiposition actuator switch 33, is provided at the end of the wand section 26 opposite the coupler 30. The end of the wand section 28 opposite the coupler 30 is received in a connector 34 mounted to the rear of the canister assembly 14. A flexible hose 36 extends from the control handle 32 to the inlet 38 connected to the dirt collection vessel 22. A
power cord (not illustrated) includes a plug for connecting to a standard electrical wall outlet and providing power for the vacuum cleaner.
During standard floor cleaning operation, the rotary agitator 18 scrubs and beats dirt and debris from the nap of an underlying carpet being cleaned. A suction generator 40 draws air entrained with that dirt and debris through the suction inlet 16, the connector 34, the wand section 28, the wand section 26, the control handle 32, the hose 36 and the inlet 38 into the dirt collection vessel 22. The dirt and debris is captured in the dirt collection vessel 22 while the now relatively clean air is drawn over the motor of the suction generator 40 in order to provide cooling. That air is then exhausted through a fmal filter (not shown) and returned to the environment through the exhaust port 41.
As illustrated in Figure 2 the handle and wand assembly 24 includes a distal end that is removable from the canister assembly 14 to allow manipulation and specialty cleaning. More specifically, the distal end of the wand section 28 is removable from the connector 34. As best illustrated in Figure 3-5, the distal end of the wand section 28 includes a spring loaded detent 50 that is biased so as to project through a hole 52 in the sidewall of the wand section. When the handle and wand assembly 24 is fully seated in the connector 34, the end 54 of the wand section 28 is seated against the bottom of the connector. Thus, the main air path from the canister assembly 14 to the handle and wand assembly 24 is tightly sealed for maximum cleaning efficiency. The detent 50 is biased into a lock opening 58 in the connector 34 to insure the integrity of the connection and seal.
When it is desired to release the handle and wand assembly 24 for above floor cleaning, the lock release 60 is manipulated. The lock release 60 comprises an L-shaped lever 62 connected to the canister assembly 14 by a pivot pin 66. The operator simply engages the toe plate 68 of the lever 62 and depresses. This causes the lever 62 to pivot about the pivot pin 66 (see action arrow A in Figure 4a). A lug 70 on the lever 62 is aligned with the lock opening 58. When the lever 62 is depressed, this lug 70 engages the detent 50 and pushes the detent 50 against its spring bias out of the lock opening 58. When the detent 50 clears the lock opening 58 (note Figure 4b), the handle and wand assembly 24 may be freely removed from the connector 34 to allow above floor cleaning.
The telescopic sections 26, 28 of the handle and wand assembly 24 may then be retracted or extended as desired to produce a wand of desired length. The handle and wand assembly 24 is then manipulated by the operator through the control handle 32. In this mode of operation air including dirt and debris is drawn into the open distal end of the handle and wand assembly 24. That air then travels through the wand section 28, the wand section 26, the control handle 32, the hose 36 and the inlet 38 into the dirt collection vesse122. There the dirt becomes trapped and clean air then passes over the motor of the suction generator 40 before being exhausted through the fmal filter into the environment.
Upon finishing the manual cleaning application, the handle and wand assembly 24 is returned to the connector 34. As this is done, the spring loaded detent 50 is again aligned with the lock opening 58. The detent 50 has sufficient force from the biasing spring to force the lug 70 from the locking opening 58 thereby locking the handle and wand assembly 24 back in the connector 34.
The foregoing description of a preferred embodiment of the present invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings.
As illustrated in Figure 2 the handle and wand assembly 24 includes a distal end that is removable from the canister assembly 14 to allow manipulation and specialty cleaning. More specifically, the distal end of the wand section 28 is removable from the connector 34. As best illustrated in Figure 3-5, the distal end of the wand section 28 includes a spring loaded detent 50 that is biased so as to project through a hole 52 in the sidewall of the wand section. When the handle and wand assembly 24 is fully seated in the connector 34, the end 54 of the wand section 28 is seated against the bottom of the connector. Thus, the main air path from the canister assembly 14 to the handle and wand assembly 24 is tightly sealed for maximum cleaning efficiency. The detent 50 is biased into a lock opening 58 in the connector 34 to insure the integrity of the connection and seal.
When it is desired to release the handle and wand assembly 24 for above floor cleaning, the lock release 60 is manipulated. The lock release 60 comprises an L-shaped lever 62 connected to the canister assembly 14 by a pivot pin 66. The operator simply engages the toe plate 68 of the lever 62 and depresses. This causes the lever 62 to pivot about the pivot pin 66 (see action arrow A in Figure 4a). A lug 70 on the lever 62 is aligned with the lock opening 58. When the lever 62 is depressed, this lug 70 engages the detent 50 and pushes the detent 50 against its spring bias out of the lock opening 58. When the detent 50 clears the lock opening 58 (note Figure 4b), the handle and wand assembly 24 may be freely removed from the connector 34 to allow above floor cleaning.
The telescopic sections 26, 28 of the handle and wand assembly 24 may then be retracted or extended as desired to produce a wand of desired length. The handle and wand assembly 24 is then manipulated by the operator through the control handle 32. In this mode of operation air including dirt and debris is drawn into the open distal end of the handle and wand assembly 24. That air then travels through the wand section 28, the wand section 26, the control handle 32, the hose 36 and the inlet 38 into the dirt collection vesse122. There the dirt becomes trapped and clean air then passes over the motor of the suction generator 40 before being exhausted through the fmal filter into the environment.
Upon finishing the manual cleaning application, the handle and wand assembly 24 is returned to the connector 34. As this is done, the spring loaded detent 50 is again aligned with the lock opening 58. The detent 50 has sufficient force from the biasing spring to force the lug 70 from the locking opening 58 thereby locking the handle and wand assembly 24 back in the connector 34.
The foregoing description of a preferred embodiment of the present invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Obvious modifications or variations are possible in light of the above teachings.
The embodiment was chosen and described to provide the best illustration of the principles of the invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the invention as determined by the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled. The drawings and preferred embodiments do not and are not intended to limit the ordinary meaning of the claims and their fair and broad interpretation in any way.
