FIG. 3 is a perspective view of the guard attached to the base; -
FIG. 4 is a perspective view of the vacuuming hose attached to the guard; and -
FIG. 5 is a perspective view of the tool attached to the guard. - The
apparatus 1 shown inFIG. 1 has parts that are examples of the elements recited in the claims. Theapparatus 1 thus includes examples of how a person of ordinary skill in the art can make and use the claimed invention. It is described here to meet the requirements of enablement and best mode without imposing limitations that are not recited in the claims. - The
apparatus 1 is a vacuuming system. It includes avacuum cleaner base 10 and ahandle 14 extending upward from thebase 10. Thebase 10 has front andrear wheels base 10 over afloor 24. Afan 30 in thebase 10 draws air through aninlet 32 of thebase 10 and exhausts the air out anoutlet 34 of thebase 10. Theoutlet 34 can be connected to afilter bag 40 suspended from thehandle 14, for thebag 40 to filter out dirt from the exhausted air. Alternatively, theoutlet 34 can be connected to ablower hose 42 to use the exhausted air to blow debris or inflate things. Anozzle 50 is connectable to theinlet 32 for vacuum cleaning thefloor 24. Alternatively, aninlet guard 52 can be connected toinlet 32 to filter room air being drawn through theguard 52 into theinlet 32. Avacuuming hose 54 can be attached to theguard 52 for vacuuming above-the-floor household surfaces. Anair tool 56 can be attached to theguard 52 for thebase 10 to power thetool 56. - The
nozzle 50 hashooks 100 that hook onto aperch pin 102 of thebase 10 and aflange 104 that is captured by alatch 106 of thebase 10. Abrushroll 110 in thenozzle 50 is configured to be coupled by abelt 112 to adrive pulley 114 of thebase 10. -
FIG. 2 shows thenozzle 50 removably attached to thebase 10. Thenozzle 50 is supported by thebase 10 in a fixed position relative to thebase 10 in that it will move in unison with thebase 10 as thebase 10 is lifted and moved. In operation, thebrushroll 110 rotates against thefloor 24 to dislodge dirt. The dirt is carried by a flow (arrows 125) of air through thenozzle 50 and theinlet 32 into thebase 10 and is exhausted through thebase outlet 34 into thebag 40. The air escapes through thebag 40 leaving the dirt retained in thebag 40. -
FIG. 3 shows theguard 52 removably attached to and supported by thebase 10 in a fixed position relative to thebase 10. Like the nozzle 50 (FIG. 2 ), theguard 52 hashooks 200 that hook onto the base'sperch pin 102 and aflange 204 captured by the base'slatch 106. At thefront end 220 of theguard 52 is afilter plate 222 withholes 224. Theholes 224 are sized to pass air and fine particles while blocking objects larger than theholes 224, such as debris and a user's finger. Aninlet tube 230, with a radially-outercylindrical engagement surface 231, extends rearward from thefilter plate 222. Theinlet tube 230 is surrounded by ashroud 234 with a cylindrical radially-inner surface 235 facing theinlet tube 230. - In operation, a flow of room air follows a
path 245 extending through thefilter plate 222 and theinlet tube 230 into thebase inlet 32 and out theblower hose 42. Theflow 245 is surrounded by a rear seal formed by and between thebase 10 and an annularrear edge 246 of theguard 52. -
FIG. 4 shows thevacuuming hose 54 removably attached to theguard 52. Dirt is carried by a flow of air along aflow path 265 extending from a surface to be cleaned through thehose 54, theguard 52 and thebase 10 into thefilter bag 40. Thefilter plate 222 filters debris 270 from the air. Finer particles are captured in thebag 40. - A friction fit is formed by and between a
connector tube 280 of thehose 54 and theengagement surface 231 of theguard 52. Thecylindrical engagement surface 231 is slightly frustoconical to facilitate the friction fit. Alternatively, the friction fit can be formed by and between thehose connector tube 280 and the radiallyinner surface 235 of theshroud 234. The friction fit, formed by theinlet tube 230 or theshroud 234, forms a seal surrounding theair flow path 265. Theshroud 234 protects theproximal end 284 of theconnector tube 280 and hides it from view. - The guard's
engagement surface 231 is circularly symmetric about anaxis 285 to enable an infinite number of possible circumferential orientations of thehose connector tube 280 about theaxis 285 over a 360° range relative to theguard 52. This enables the user to mount thehose connector tube 280 to theguard 52 without regard to circumferential orientation of theconnector tube 280. Once mounted, theconnector tube 280 is inhibited, by friction of the friction fit, from being withdrawn or turned. - The
engagement surface 231 of theguard 52 can be designed to match theengagement surface 291 of thebase outlet 34 that is friction fitted to thebag 40 and the blower hose 42 (FIG. 3 ). This would enable the samehose connector tube 280 to be friction fitted over both theguard 52 and thebase outlet 34. Thevacuuming hose 54 could then be made identical to the blower hose 42 (FIG. 3 ) to reduce the number of different parts. -
FIG. 5 shows thetool 56 removably attached to and supported by theguard 52 in a fixed position relative to thebase 10, with thebase 10 resting on atable top 400. Thetool 56 includes anair motor 410 powered by the air (arrows 415) drawn through thetool 56 and theguard 52 to rotate anarbor 420 about itsrotational axis 425. Thearbor 420 is a shaft to which atool bit 430, in this case a grinding wheel, is fixed.Debris 438 passed through theair motor 410 is blocked by thefilter plate 222 from entering thefan 30. Finer particles are caught in thefilter bag 40. - A
connector tube 440 of thetool 56 is identical to theconnector tube 280 of the vacuuminghose 54. It is rigidly fixed to theair motor 410 and centered on atube axis 445 that perpendicularly intersects therotational axis 425. Theinner surface 441 oftube 440 contacts theouter surface 231 of the guard'sinlet tube 230 in a friction fit. Alternatively, thetube 440 is friction fitted to theinner surface 235 of the guard'sshroud 234. The friction fit, formed by either theinlet tube 230 or theshroud 234, surrounds the air flowing through theguard 52 into thebase inlet 32. The friction fit coincides with an annular seal surrounding the air flowing through theguard 52. - As explained above, the
engagement surface 231 is circularly symmetric about thetube axis 445. This enables the user to orient thetool 56, thearbor 420, thetool bit 430 and therotational axis 425 in any orientation relative to the base 10 about thetube axis 445 over a 360° range. Once mounted to theguard 52, thetool 56 is inhibited by friction of the friction fit from being withdrawn from or turned about theguard 52. This fixes the selected orientations of thetool 56, thearbor 420, thetool bit 430 and therotational axis 425 relative to thebase 10. However, the user can adjust (arrow 465) the orientation of thesecomponents tool 56 about thetube axis 445 with enough force to overcome the friction. This forces the contactingsurfaces tool 56 from theguard 52 to loosen or break the seal before turning thetool 56 to a new orientation. - The user can adjust the horizontal position of the
tool 56, thearbor 420, thebit 430 and therotational axis 425 by wheeling the base 10 forward or rearward, on itswheels table top 400. - In another configuration, the
tool 56 is connected to the base 10 through the vacuuminghose 54 shown inFIG. 4 . The hose'sproximal connector tube 280 is attached to theguard 52, and the hose'sdistal connector tube 480 can be friction fitted into theconnector tube 440 of thetool 56. - In yet another configuration, the guard's
inlet tube 230 and theconnector tubes hose 54 andtool 56 are splined. This reduces the number of possible orientations of theconnectors - This written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to make and use the invention. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art. Such other examples are intended to be within the scope of the claims if they have elements that do not differ from the literal language of the claims, or if they include equivalent structural elements with insubstantial differences from the literal language of the claims.
