Definitions
- My invention relates to a cleaning tool for a vacuum cleaner and in particular to a dual purpose tool which is useful for cleaning both floors (hardwood, tile, linoleum) and rugs or carpets.
- Dual purpose iioor cleaning tools are known in which the nozzle body of the tool is provided with a pair of dissimilar cleaning surfaces, one on each side of the nozzle body.
- the oor cleaning surface comprises an aperture surrounded by a fixed brush for loosening dust, dirt, etc. adhered to the floor and for sweeping dust and dirt out of depressions in tile and linoleum oors.
- the rug and carpet cleaning surface of the tool comprises an aperture surrounded by smooth surfaced rug pads in Order to minimize friction since a tool with a xed brush requires considerable effort to move it over a rug or carpet.
- the nozzle body rotates about the associated nozzle elbow and a valve mechanism is provided in the nozzle body so that only the nozzle aperture associated with the selected cleaning surface communicateswith the vacuum cleaner via the nozzle elbow and tool handle or wand.
- a dual purpose floor and carpet cleaning tool in which the nozzle body has but one cleaning surface which is convertible to a floor cleaning use and a carpet cleaning use by means of movable brushes. That is, brushes are placed in position adjacent the aperture of the nozzle body for cleaning floors and are withdrawn from this position for cleaning carpets and rugs.
- a dual purpose iioor and rug cleaning tool having movable brushes in accordance with my invention is less expensive to manufacture than the known dual purpose tool since the valve and its operating mechanism is eliminated, while on the other hand the means for mounting the brushes on the tool are extremely simple to manufacture and assemble, are highly reliable in operation and easily operated by the person using the tool.
- an object of my invention is to provide a floor and rug cleaning tool having movable brushes whereby the tool is converted for the desired use.
- Another object of my invention is to provide a dual purpose oor cleaning tool which is inexpensive.
- a further object of my invention is to provide a dual purpose floor cleaning tool of simple construction in which ra rst brush is pivotally mounted for movement between its operative and inoperative position in a simple manner and a second brush is appropriately positioned according to the selected position of the iirst brush for floor or rug cleaning.
- FIG. 1 is a front elevation of a oor cleaning tool according to the invention.
- FIGS. 2 and 3 are views similar to FIG. 1 showing the pivotal movement of one brush from a floor cleaning position, FIG. 1, to a rug cleaning position, FIG. 3.
- FIG. 4 is a cross section taken on line 4--4 of FIG. 3.
- FIG. 5 is a cross section taken on line S-S of FIG. l.
- FIG. 6 is a cross section taken on line 6--6 of FIG. 1.
- FIG. 7 is a cross section taken on line 7--7 of FIG. 1.
- FIG. 8 is a bottom plan view of FIG. 1 showing a detail of the invention.
- FIG. 9 is an end view of a tool as seen in FIG. 3.
- the dual purpose cleaning tool comprise a nozzle body 10 having a suitable suction aperture and an elbow 11 which is pivotally attached to the body 10 in any suitable manner.
- a brush 12 and associated brush housing 20 are mounted at the front of the body 10 for rotation about a pin 13.
- the housing 20 is journalled on the pin 13 in any known simple manner so that the brush 12 can rotate 180 from the position shown in FIG. 1 to the position shown in FIG. 3.
- the brush housing 20 cannot rotate more than since it engages levers 17 and 26 in each of its operative positions (FIGS. 1 and 3) as will be clear from the following description given in connection with FIGS. 4, 5, and 7.
- a second brush 14 which is seen in FIG. 2, extends from the body 10 adjacent the rear edge of body and in its oor cleaning position the brush 14 is fixed in this extended position.
- the brush 14 retracts into the body 10 for cleaning rugs (FIG. 3).
- Movement of the brush 14 between its extended position, for floor cleaning, and its retracted position, for cleaning carpets, is determined by this position of the brush 12. This is accomplished, as seen in FIGS. 4 and 5, by a lever 15 which is pivotally attached to the body 10.
- the lever 15 has a reverse bend or cam 16 at one end for engaging the brush 14 and an arm 17 extending through a slot 18 into engagement with the pivotal brush housing 20.
- a vertically elongated slot 32 may be provided at each end of the nozzle body 10.
- the brush 14 in such a case being provided with a longitudinally extending rod which is received in the slot 32 and having end caps 31 which extend beyond the edges of the slot to limit axial movement of the brush.
- a sliding latch 30 which is adapted to engage a pin on the brush housing 20 to lock the brush 12 in both of its operative positions.
- the brush 14 can be fully retracted and held within the well 19.
- the brush 14 be allowed to act under the influence of gravity to lightly brush the nap of the rug or carpet being cleaned.
- a rod 25 having a pair of levers 26 and 27 xed at each end is provided as shown in FIGS. 6, 7, and 8.
- the levery 27 at ⁇ the opposite endof rod 25 (FIG. 6) ⁇ does not ⁇ project from the body 10.
- Each of the levers ⁇ i26and 27 extend over the brush 14.
- the lever ⁇ 15 and the rod 25 with associated levers 26 and 27 may be ⁇ biased into one operative ⁇ position by a suitable spring. However, ⁇ the lever 15 and rod 25 can be allowed to pivot freely since movement of the levers 15, 26, and 27 by brush housing 20 is controlled in a positive manner.
- a dual purpose cleaning tool comprising an elongated nozzlebodyhaving a cleaning surface and an elbow member ⁇ projectingtherefrom for connecting said brush means connected thereto yfor pivotal movement relativeto said body, said first brush member extending inthe elongated "directionof said nozzle body and having a first operativeposition in which the "bristles of said brush means extend outwardly of said nozzlebody beyond ⁇ said cleaning surface and a second operative position in which thebristles of said brush means extend in the opposite direction remote from said cleaning surface, said nozzle body having a well extending in the elongated direction thereof and opening into said cleaning surface, a second brush means within said well movable between a retracted position in which said second brush resides within ⁇ said Well and an extended position in which the bristles of said second brush means projecttfrom said Well outwardlybeyond said cleaning surface, lever means pivhaving an outer end projecting from said nozzle body into the plane of said iirst brush means'ad
- said lever means includes a first pivotal lever having a camming surface at one end within said well and an arm extending outwardly of said ⁇ body ⁇ for deiining said outer end extending into the plane of said first brush, and a second lever system including a rod rotatably mounted within said body, said rod being coextensive with said body in a plane substantially parallel with said irst brush, said rod having a lever iixed thereto at each end, each of said rod levers extending into said well for engagement with said second brush, and one of said rod levers having an outer end projecting into the plane of said iirst brush for extending said second brush from said well and lixing saidy second brush in said extended position when saidirst brush is similarly positioned.
- a dual purpose cleaning tool comprises a rod rotatably mounted within said body in a plane substantially parallelk with said first brush, said rod having a lever lixed thereto at each end, each of said rod levers extending into said well at one end for ⁇ engagement with said second brush, one of said levers having an outer end projecting into the plane of said first brush for extending said second brush from said rwell and fixing said second brush in said extended position when said iirst ⁇ brush is similarly positioned.
