Definitions

  • the present invention relates to a stick type vacuum cleaner having a porous filter bag and a re-usable dirt cup, the latter being for accumulating dirt picked up from the rug, or the like, during the vacuuming operation.
  • Stick type vacuum cleaners are known in which each of the cleaners is provided with a vacuum pump, a dirt tube and a porous bag for receiving the dirt entrained in the air stream and conducting the dirt into a reusable dirt cup that is attached to the housing of the vacuum cleaner.
  • a vacuum pump for supplying the dirt to the housing of the vacuum cleaner.
  • a dirt tube for supplying the dirt to the housing of the vacuum cleaner.
  • a porous bag for receiving the dirt entrained in the air stream and conducting the dirt into a reusable dirt cup that is attached to the housing of the vacuum cleaner.
  • DE-A-34 30 402 discloses a handle having two grasping portions such as the claimed invention.
  • this vacuum cleaner can be used in an upright position and in a horizontal position but not for above-floor operations as intended by the claimed invention Consequently, it is an object of the present invention to provide a two position handle for a stick vacuum cleaner which can be used in one position for up-right cleaning and in another position for above-floor cleaning operations and for substantially horizontal cleaning in conjunction with a molded-in handle on the lower housing of the cleaner.
  • stairs and risers can be adequately vacuumed.
  • the present vacuum cleaner is a light-weight, up-right construction and includes a vacuum motor for drawing dirt laden air into a housing, and discharging the dirt into a dirt cup as the air passes through a porous filter bag.
  • the invention is disclosed in the characterizing part of claim 1 in connection with the preamble of the claim itself.
  • the lightweight stick type vacuum cleaner as seen in Figs. 1-4 is provided with a lower housing 10 having a tubular extension 12 and the nozzle 14 pivotally attached to the extension 12 at pivot point 16.
  • a motor 18 and an impeller fan 20 are mounted in the lower housing 10 forming a vacuum pump for the cleaner.
  • a dirt tube 22 is also provided for conducting air-entrained dirt into a porous filter bag 24.
  • the lower housing is connected to the upper handle assembly 26 by means of a cylindrical handle tube 28 located behind the porous bag and removable dirt cup 30. Consequently, dirt-laden air which enters the vacuum cleaner device through the opening 14a in the nozzle moves through the dirt tube 22 and exits into the bottom of the porous cloth filter bag 24, and thereafter the air-entrained dirt falls by gravity into the dirt cup 30, while the air flow continues up into the filter bag 24 and out to the atmosphere through the minute openings of the filter bag.
  • the bag shaker 32 is provided at its upper end with a pair of springs 36, each being attached at one end to the shaker mechanism 32 and at the other end to the handle assembly 26.
  • the handle assembly is in the form of a closed loop provided a void 38 for inserting the fingers of the hand therethrough.
  • Figs. 5 and 6 showing the handle portion 26 of the vacuum cleaner which has a two-position hand grip, in which one hand grip portion 39 is substantially linear, and in which a second handle portion 40 is integral with the hand grip portion 39, and is at an obtuse angle thereto.
  • the user/operator of the vacuum cleaner will use the handle portion 40 when the cleaner is held at an angle for cleaning floors and floor coverings, as seen in Fig. 3, and the handle portion 39 is utilized when vacuuming stairs and risers, as seen in Fig. 7.
  • a hand-hold 42 is provided in lower housing 10 which particularly utilizes the construction, seen in Fig. 7, as well as in Figs. 1-3.
  • the handle 26 is provided with a reduced cylindrical insert 27 which fits within an end 29 of the cylindrical handle tube 28 which connects the lower housing to the handle assembly.
  • a cord retainer 43 At the bottom of the handle 26 is a cord retainer 43 while at the top of handle 26 is mounted a cord retainer 44, for wrapping the electric power cord when not in use.
  • the hand grip portions 39 and 40 are shaped for gripping the selected handle portion without the operator's hand slipping out of position.
  • FIG. 2a An alternate embodiment of the present invention is illustrated in Fig. 2a showing the dirt tube 22a extending behind the dirt cup 30 and entering the porous filter bag 24a at an intermediate portion thereof, or at top of the bag.
  • the dirt tube functions not only to conduct the dirt-laden air into the filter bag but also acts as the connecting support member between the lower housing 10 and the handle assembly.
  • the nozzle of the present stick vacuum cleaner is provided with a small wheel assembly 50 as shown in Figs. 9-13.
  • the nozzle opening 52 is provided with a bristle strip 54, as clearly seen in Figs. 9 and 10.
  • the nozzle housing 56 has an opening 58 through which a rocker foot pedal 60 projects, as shown in Figs. 10.
  • Figs. 12-14 The embodiment shown in Figs. 12-14 is provided with large nozzle propelling wheels 62 for ease in movement of the nozzle head.
  • Pivotally secured to the nozzle casing 56 is an elbow 64 for insertion within the tubular extension 12 of the lower housing 10, as particularly seen in Fig. 2.
  • the alternate embodiment of the nozzle construction is provided with a bristle strip 68 in the opening 70 of the nozzle housing 72.
  • a removable dirt cup 30 is illustrated in Figs. 8 and 16-19, and which is adapted to be inserted in the opening 33 between the hand hold 42 and the porous cloth bag 24, (Fig. 8).
  • the dirt cup 30 is provided with a latch assembly referred to generally by the reference numeral 76, and particularly shown in Figs. 20-25 of the drawings.
  • the dirt cup has a keyway 35 in the bottom thereof for accommodating the latch assembly 76, and a track 37 on the top surface of the lower housing 10.
  • the latch assembly 76 in addition, is provided with somewhat flexible legs 78 having end hooks 80.
  • the latch assembly 76 is provided with an element 82 having slightly flexible finger pieces 84, as well as a cam 86 on the bottom of the latch.
  • the latch assembly 76 fits within the dirt cup 30 and has limited movement therein but cannot be removed therefrom. Consequently, when it is desired to install the dirt cup 30 within the opening between the lower motor housing and cloth dirt bag, the cup 30 is pushed into the opening and slides on the track 37 on the lower housing 10 and the cam 86 located on the bottom of the latch wedges against the lower housing of the vacuum cleaner thus locking the dirt cup in place on the stick vacuum. Since the latch assembly 76 moves freely with limited movement within the dirt cup the latter can be removed by squeezing the latch finger pieces 84 and pulling out the latch assembly whereby the cam 86 is released from the lower housing. The latch assembly, however, cannot be separated from the dirt cup since it is retained within the cup by the end hooks 80 of the legs 78 being retained in the keyways 35 of the dirt cup 30.
  • Fig. 19 shows the latch assembly 76 fully inserted within the keyway 35 of the dirt cup 30. It will again be noted that when the dirt cup 30 is pushed in the opening 33 and assumes the position shown in Fig. 2 the cam 86 of the latch assembly 76 is forced into engagement with the top surface of the lower housing 10 thereby maintaining the dirt cup into a latched position in the open space 33 between the bottom of the porous cloth bag 24 and the top of the lower housing 10.
  • the dirt cup is provided with an open top 30a communicated with the porous bag 24 in order to permit the free fall of air-entrained dirt into the dirt cup 30. Furthermore, as stated above, the dirt cup 30 can be removed from the stick vacuum cleaner by grasping the finger pieces 84 on the latch assembly 76 and pulling the latch in a direction out of the dirt cup a limited distance thereby causing the cam 86 to be dislodged from engagement with the top surface of the lower housing 10.
  • an on/off switch 95 is shown which is connected to a power source (not shown) and which is provided in the handle 26 for operating the present stick vacuum cleaner.
