Definitions

  • the present invention relates to floor cleaning devices and more particularly to vacuum cleaners.
  • Upright vacuum cleaners normally have a floor sweeper portion which is rolled over the surface to be cleaned, and an upright handle assembly or tank support assembly pivotally mounted to the sweeper portion.
  • Some upright vacuums have a single rod handle to which is attached a flexible collection bag, while others have two side bars between which ia secured a rigid collection tank or bag housing.
  • the handle assembly ia pivotally secured to the floor sweeper portion to allow the operator to push the vacuum cleaner along the surface to be cleaned.
  • Within the tank housing is a vacuum motor and a support surface for supporting the dirt collecting bag.
  • a standpipe or hose normally extends from the lower portion of the tank housing to the upper portion and terminates in a curved end so that the dirt is deposited into the top of the collecting bag by the standpipe or hose.
  • Some upright vacuums utilize a wire clip or securing device located on the outside of the tank near the handle grip to prevent the electrical cord from trailing on the floor immediately behind the sweeper portion, thus preventing the sweeper portion from running over the electrical cord.
  • some upright vacuum cleaners develop problems relating to the orientation of the upright standpipe in the tank housing. Since the standpipe has a curved "L-shaped" upper portion, the standpipe must be oriented correctly to be connected with the dirt collecting bag. These standpipes are often positioned by a clamp which passes around the standpipe and is secured to the wall of the tank housing. Unfortunately these standpipes have the tendency to twist in use and their short upper leg, in the 8 L 8 , may wear against the side walls of the collecting bag at the connecting juncture with the bag. Also the opening of the standpipe may become restricted if the pipe is twisted during operation so that the outlet end turns against the side of the bag. During assembly of the tank housing, an assembler is required to correctly orient the standpipe which necessitates manually checking this orientation.
  • a handle mounting bracket pivotally mounted on floor engaging housing, includes an upper cross piece with mounting portions which extend beyond each of two handle side legs. Each side leg and mounting portion includes means for securing the handle assembly to the mounting portions.
  • the mounting bracket is pivoted about a pivot axis that is oriented generally horizontally and perpendicular to the direction of travel of the vacuum cleaner, while the mounting portions define mounting surfaces that are oriented generally parallel to the mounting bracket pivot axis.
  • an elongate cord channel is mounted to one handle side leg and has a base and resiliently deformable sides.
  • the cord channel sides are sufficiently resilient that they may be separated for insertion of an electrical cord which will be maintained in a trapped storage condition between the sides.
  • the standpipe has an integrally formed flat that will abut the inner wall surface of the tank housing maintain the curved end of the standpipe in the proper bag connecting position during the assembly and operation of the vacuum cleaner.
  • the tank housing is maintained between the handle assembly side legs.
  • the vacuum motor within the tank housing includes an impeller opening guard that protects the impeller opening and which is not removable. It includes a screen and mounting ring. The combined area of all of the openings through the screen grid within the confines of the mounting ring is equal to or greater than the area of the impeller opening to avoid restricting air flow to the impeller.
  • the mounting ring is fixedly secured to the motor so that the guard is nonremovable.
  • the upright vacuum cleaner 1 (Fig. 1) includes a floor engaging housing 2 and an upright handle assembly 3.
  • a handle mounting bracket 20 (Fig. 2) is pivotally secured to floor engaging housing 2.
  • Mounting bracket 20 includes bracket side legs 22 and a cross beam 28.
  • Cross beam 28 has mounting surfaces 29 that extend beyond bracket side legs 22, to which handle aide legs 16 are secured by securing means 31.
  • An elongate cord channel 62 (Figs. 7, 9) is mounted along one of the handle side legs 16.
  • Cord channel 62 has a channel base 64 from which extend channel sides 66 which are resiliently deformed so that channel sides 66 may be separated from each other to receive and maintain an electrical cord 78 in a trapped storage condition between them.
  • a vacuum tank 10 (Fig.
  • a collecting bag support 44 has a standpipe 46 which transports dirt from the base of tank housing 10 to the tank upper region to be deposited in a collecting bag (not shown).
  • Standpipe 46 has a curved top 52 that connects to the top of the collecting bag, and an integrally formed standpipe flat 54 (Fig. 6) near curved top 52, positioned to abut the inside of tank 10 and maintain standpipe 46 in its proper orientation.
  • Vacuum motor 41 (Fig. 13) has an impeller and an impeller opening 43 which is protected by an impeller opening guard 92.
  • Impeller opening guard 92 includes a guard screen 94 and a mounting ring 96, in which the combined area of all of the openings defined by screen 94 and bounded by ring 96 is greater than the area of impeller opening 43.
  • Mounting ring 96 is fixedly secured to motor 41 so as to be nonremovable.
  • Vacuum tank 10 is molded of plastic and has a front cover 12, a tank back 14 (Fig. 4) and tank sides 15 (Fig. 5).
  • Generally upright handle side legs 16 (Figs. 2, 5) extends upward along either side of the entire length of tank 10.
  • a handle 18 joins the tops of side legs 16 to provide a somewhat rectangular purchase for propelling vacuum cleaner 1.
  • An upwardly opening storage hook 19 extends laterally to one side of handle 18, just above its juncture with handle side legs 16, and is integrally molded with handle 18. Storage hook 19 allows the vacuum cleaner power cord 78 to be coiled and neatly hung on the side of vacuum 1.
  • Tank back 14 is fastened to side legs 16 by any conventional means which fixedly secures back 14 to side legs 16.
  • Handle mounting bracket 20 has an inverted 'U' shape which includes two depending bracket side legs 22 and a connecting bracket top 24. Legs 22 and top 24 are formed from a single piece of flat stock bent into the desired configuration (Fig. 3). Through the lower end of each bracket leg 22 is a sweeper portion pivot aperture 26. Bracket 20 is pivotally mounted on floor engaging housing 2 through apertures 26 by any conventional method, so that bracket 20 may be locked in an upright position or pivoted downward for use.
  • a cross beam 27 (Figs. 3-5) is welded to the upper surface of top 24, with the ends of cross beam 27 extending past legs 22 in.order to form mounting portions 28.
  • Bracket 20 has a bolt aperture through each mounting portion 28, and has mounting surfaces 29 on the upper surface of each mounting portion 28.
  • a plug 32 is fixed in the bottom end of each side leg 16.
  • a threaded aperture in each plug 32 for receiving mounting bolts 31 is positioned so that the bottom of handle side leg 16 and plug 32 rests on mounting surface 29.
  • bracket legs 22 Because the mounting portions 28 extend beyond bracket legs 22, bolts 31 are easily accessible and mounting and dismounting of handle assembly 3 to bracket 20 is facilitated.
  • Tank front cover 12 is pivotally connected to handle mounting bracket 20 at cover pivot axle 33 (Figs. 3-4).
  • Pivot axle 33 is a rectangular rod which extends between, and is rotatably mounted to, bracket legs 22 at each axle end 34.
  • Tank front cover 12 has a rearwardly extending connecting flange 36 which is bolted to the top of pivot axle 33.
  • Axle ends 34 are spaced from bolts 31 to avoi.d interference.
  • a resilient gasket 38 is mounted on tank back 14 to contact and seal tank front 12 when it reaches the closed position, as shown in Figure 4.
  • a latch 40 (Fig. 5) selectively secures .tank front 12 in a closed position. Disengagement of latch 40 allows access to the dirt bag when it should be emptied or discarded.
  • a vacuum motor 41 (Fig. 5) which induces a vacuum through the vacuum cleaner.
  • Motor 41 is provided a power source by an electrical conductor 42 (Fig. 2) which extends from floor engaging portion 2 through a strain relief 42a to vacuum motor 41.
  • Motor 41 sucks air through impeller opening 43 (Fig. 13) to produce a vacuum.
  • a guard 92 (Figs. 11-13) covers impeller opening 43 and prevents foreign objects from entering impeller opening 43 .
  • Guard 92 includes a guard screen 94 over the opening defined by mounting ring .96.
  • Ring 96 has on its motor facing surface a heat resistent adhesive that fixedly adheres ring 96 to motor 41.
  • Ring aperture 97 has a larger diameter than impeller opening 43, ao that the combined area of all the openings defined by screen 94 is equal to or greater than the area of impeller opening 43. Therefore guard 92 does not restrict the air flow through impeller opening 43.
  • a standpipe 46 (Figs. 5, 6) has a substantially straight body 48 that extends through the bottom of tank back 14 up to near the uppermost portion of back 14. Standpipe 46 is communicative with a connecting hose 50 (Fig. 2) that transports the dirt from floor engaging housing 2 up to tank 10. Standpipe 46 has a curved top 52 so that standpipe 46 can be connected with a dirt collecting bag to deposit the dirt into the upper portion of the collecting bag. Beneath curved top 52 is a flat 54 that is integrally formed with standpipe 46. Flat 54 has a planar face 56 formed on a shoulder 58 that extends from the aide of standpipe 46. Flat 54 is oriented to position curved top 52 for connection to the dirt collecting bag when flat 54 contacts a tank aide 15. Flat 54 has two apertures 60 surrounding fasteners which are used to connect flat 54 to a tank side 15.
  • Cord channel 62 extends for substantially the entire length of side leg 16.
  • Cord channel 62 has a base 64 from which two sides 66 extend to form a roughly triangular shaped channel (Figs. 8-9).
  • Channel sides 66 converge towards each other and terminate in a curved cap 68 separated by a break 70.
  • the side of base 64 that contacts side leg 16 has a concave surface 72 defining shoulders 74 at the transition to sides 66.
  • the relaxed radius of curvature of concave surface 72 is less than the radius of curvature of side leg 16.
  • cord channel 62 When cord channel 62 is mounted on side leg 16 by fasteners 76, the stressed radius of curvature of arced surface conforms to that of the side leg 16 for compressing curved cap 68.
  • An electric cord 78 extends downward through cord channel 62 and is trapped in a storage condition between channel sides 66. Electric cord 78 may be readily removed from cord channel 62 since sides 66 are elastically deformable.
  • Electric cord 78 has a ring strain relief 82 (Figs. 7-10) which ia slidably carried on cord 78 and releasably secured to storage hook 19.
  • Strain relief 82 includes an oval plate 84 through which pass a ring aperture 86 and a cord aperture 88.
  • Through ring aperture 86 is a ring 90 which has a diameter sufficiently large to pass over hook 19.
  • Cord aperture 88 is large enough to receive and frictionally engage cord 78, but which will allow cord 78 to slide when sufficient force is applied to cord 78.
  • strain relief 82 prevents cord 78 from being continually torn from cord channel 62 and also prevents damage to electric cord 78.
  • the assembly of tank 10 and side leg 16 is secured to handle mounting bracket 20 by two bolts 31.
  • all that is required is that the two bolts 31 be removed, electrical cord 42 be disconnected, and cord 78 removed from its channel 62.
  • the entire rear tank assembly can then be removed from the lower floor engaging portion 2.
  • front tank 12 may also be easily removed from handle mounting bracket 20 by disengaging fastener 34a on one end of the pivot axle 33.
  • Handle mounting bracket 20 is pivoted about an axis that is oriented generally perpendicular the direction of travel of the vacuum cleaner.
  • Upper cross beam 28 have mounting surfaces 29 that are oriented generally parallel to this pivot axis so that when an operator pushes on handle 18, side legs 16 are forced directly against mounting surfaces 29.
  • cord channel 62 With elongate cord channel 62 mounted on a side leg 16, the electric supply cord 78 can be carried within cord channel 62 out of the way of the vacuum cleaner operator and also be hidden from view. To remove cord 78 from channel 62 the operator merely pulls cord 78 away from side leg 16 which opens channel sides 66 allowing the cord 78 to escape. Channel sides 66 retain sufficient resiliency to hold cord 78 in place even after repeated removal and storage.
  • Cord channel 62 also acts as a strain relief in that should sufficient force be applied to cord 78, the cord will be stripped out of channel 62 instead of damaging the cord. Ring strain relief 82 also prevents damage to cord 78. Since oval plate 84 is frictionally carried on cord 78, when sufficient force is applied to cord 78, strain relief 82 will slide on cord 78 and absorb a shock which would otherwise be imparted to the cord 78.
