DESCRIPTION OF THE PREFERRED EMBODIMENT
The lightweight stick type vacuum cleaner, as seen in Figs. 1-5, 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. As seen in Fig. 2, an electric 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 2~.
The lower housing i~ connected to the upper handle assembly 26 by means o~ a cylindrical handle tube 28 located behind the porous bag and removable dirt cup 30.
Consequently, dirt-laden air whlch enters the vacuum cleaner device through the opening 14a in the nozzle moves through ~o3~7 the dirt tube 22 and exits into the bottom of the porous cloth filter bag 2~, 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 atmo-sphere through the minute openings of the filter bag! ~ow-ever, sometimes in use, some dirt and debris cling6 to the inside of the porous bag 24 and is removed by means of a bag shaker 32 having a lower ring 34 attached to the top of the filter bag 24. 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.
It should be noted that the handle assembly is in the form of a closed loop provided a void 38 for inserting the fingers of the hand therethrough.
Referring particularly to Figs. 5 and 6 showin~ 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 ,3~l~7 EU~343 40 is integral with the hand grip portion 39, and is at an obtuse angle thereto. Thus, 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. In order to make the vacuuming of stairs and risers easier to accomplish 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.
As illustrated in Fig. 2, the handle 26 is provided with a reduced cylindrical insert 27 which fits within an end 29 o the cylindrical handle tube 28 which connects khe lower housing to the handle assembly.
At the bottom of the handle 26 is a cord reta.iner 43 while at the top of handle 26 is mounted a cord retainer 44, for wrapping the electric power cord when not in u6e. As further seen in Figs. 5 and 6, the hand grip portions 39 and ~0 are ~hapecl ~ur ~ripping th~ ~a~ ad ~la.ndl3 ~.L~io~
without the operator~ 6 hand 6 lipping OU L. O -L ~os.i' .ion .
.
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. In this construction, 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 pro-vided 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. In addition, the nozzle housing 56 has an opening 53 through which a rocker foot pedal 60 projects, as shown in Figs. 10.
The embodiment shown in Figs. 12-15 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 in~ertion within the tubular extension 12 - 2 ~ 7 of the lower housing 10, as particularly seen in Fig. 2 As seen in Fig. 13 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 par-ticularly shown in Figs. 20-25 of the drawings. As seen in Fig. 8 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 lO. The latch assembly 76, in addition, is provided with somewhat flexible legs 78 having end hooks 80. Furthermore, the latch assembly 76 is provided with an element 82 having slightly flexible finger pieces 8~, as well as a cam 86 on the bottom of the latch.
The latch assembly 76 ~its 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 2~33~7 within the opening between the lower motor housing and cloth dirt bag, ths cup 30 is pushed into the openiny 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 la-tch assembly 76 moves ~reely with limited movement within the dirt cup the latter can be removed by squee~ing the latch finger pieces 84 and pulllng out the latch assembly whereby the cam 86 is released from the lower housing. The latch assernbly, how-ever, 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 grooves 41 of the track 37.
Fig. 19 6how6 the latch assembly 76 -fully in6erted within the keyway 35 of the dirt cup 30. It will again be noted that when the dirt cup 30 i6 pushed in the opening 33 and a66umes the po~ition shown in Fig. 2 the cam 86 o the latch ass~mbly 76 is forced into engagement with the top surface o the lower housing 10 thereby maintaining the dirt cup into a latched position in the open space 33 between the ~ ~ 2 3 3 l~ 7 ~U-343 bottom of the porous cloth bag 24 and the top of the lower hous ing 10 .
As seen in Fig. 2, 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.
~ s seen in Figs. 1-6 an on/ofE 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.
While the invention had been di.sclosed and described herein with reference to a certain embodiment, it is ~3~ 7 apparent that other variations and modifications may be made which will fall within the true spirit and scope of the in-ventions, as defined in the following claims:
