Definitions

  • the present invention relates to surface cleaning tools adapted to be connected to a separate source of suction.
  • An object of the invention is to provide a cleaning tool having a handle mounted to transmit the vertical components of the propelling forces to the surface being cleaned, and a nozzle mounted for vertical adjustment as a result of engagement with the surface. Another object is to provide a cleaning tool wherein the nozzle has a fixed low position for surfaces such as bare floors, and is vertically adjustable to an optimum position for pile surfaces, such as rugs, as a result of engagement with the latter. Another object is to provide a cleaning tool wherein the handle propelling forces can be transferred to the nozzle when the latter is in its highest position. Still another object is to provide a cleaning tool having a handle mounted to transfer components of the forces applied to the handle to the nozzle to raise the latter.
  • Figure 1 is a side view with parts broken away showing one embodiment of the invention
  • Figure 2 is a section along the line 2-2 in Figure l, and
  • Figure 3 is a partial view of Figure 1 but showing the elongated slots arranged in an upward and rearward direction.
  • the embodiment of the invention described in Figures 1 and 2 comprises a body having an elongated nozzle 11 at its forward end and a rearwardly extending bracket 12 secured thereto by rivets 13.
  • the nozzle 11 is provided with a mouth 14 defined by a perimeter lip 15 and has an outlet 16 for escape of dirt laden air.
  • a brush 17 is disposed in a housing 18 adjacent the mouth 14, and a pair of springs 19 urge the brush 17 into engagement with the surface 20 to be cleaned.
  • a latch not shown can be provided to lock the brush 17 in retracted inoperative position out of engagement with the surface 20.
  • the bracket 12 has a top wall 21, depending opposed side walls 22 and an end wall 23, and secured to the latter by rivets 24 is a wheel bracket 25 rotatably supporting a shaft 26 on which is journaled an elongated roller 27.
  • the roller 27 engages the surface 20 to form a rear support for the body 10 and the shaft 26 provides a pivotal axis for the body 10.
  • An elongated vertical opening 28 is formed in each side wall 22 and are arranged between the nozzle 11 and the pivotal axis 26. Extending through the openings 28 is a wheel shaft 29 rotatably supporting at its opposite ends a thrust wheel 30 engaging the surface 20.
  • the elongated openings 28 permit relative displacement between the body 10 and the shaft 29 and such move ment is limited by the shaft 29 engaging either the bottom 31 or top 32 of the walls defining the openings 30.
  • an opening 33 Formed in the top wall 21 of the bracket 12 is an opening 33 through which projects spaced arms 34 of a bail 35 each provided with an opening 36 to rotatably support the bail 35 on the wheel shaft 29.
  • the bight 37 of the bail 35 is attached to a coupling 38 connected to one end 39 of a resilient conduit 40 the opposite end 41 of which is secured to the outlet 16 of the nozzle 11 for communication with the mouth 14.
  • a wand 42 which also acts as a propelling handle, is removably attached to thecoupling 38 by a friction fit and afiixed to the opposite end of the wand 42 is an unshown hose which is connected to a suction cleaner in a well known'manner for conveying dirt laden air from the nozzle mouth 14 to the cleaner which removes the dirt from the air stream prior to discharging the latter to atmosphere.
  • a torsion spring 43 is arranged about the wheel shaft 29 and is attached to one side wall 22 of the bracket 12 and one leg of the bail 35. The spring 43 is of such strength to prevent the nozzle 11 from pivoting downwardly when the body 10 is lifted off the surface 20 but does not interfere with displacement of the wheel shaft 29 in the elongated openings 28.
  • the unshown hose When the tool is employed to clean a surface represented at 20, the unshown hose is connected to a source of suction to provide a suction air stream through the nozzle mouth 14 for removing dirt from the surface being cleaned.
  • the tool is propelled over the surface 20 on the wheels 30 and roller 27 by applying forces to the wand 42, and such forces are transmitted through the bail arms 34 to the wheel shaft 29 and then to the wheels 30 onto the surface 20.
  • the elongated openings 28 in the frame 12 permit the wheel shaft 29 to be displaced with respect to I the nozzle 11 so that the vertical component of the forces applied to the handle 42 are not transferred to the nozzle 11 with the result the nozzle lip 15 rests lightly on the surface 20.
  • the elongated openings 28 allow the body 10 to pivot about the roller axis 26 when the nozzle lip 15 engages different types of pile surfaces to automatically adjust itself to the surface so that the nozzle 11 in effect floats with respect to the surface 20.
  • the brush 17 may be adjusted to an extended position to engage the surface being cleaned or retracted to an inoperative position.
  • the embodiment of the invention shown in Figure 3 is similar to that previously described except the elongated opening 28 are arranged to extend in an upward and rearward direction as indicated by the numeral 45.
  • the forward horizontal component of a pushing force on the wand 42 to propel the cleaner forward is transferred to the inclined wall 46 of the openings 45 and tends to lift the nozzle 11 about the pivotal axis 26 and thus less effort is required to initiate movement of the tool away from the user.
  • the shaft 29 can be raised with respect to the elongated openings 45 and the vertical component of this force is applied to the inclined edges 46 and tend to lift the nozzle 11 with respect to the surface 20.
  • a cleaning tool comprising, a body having a downwardly facing suction nozzle at its front end, a suction passage formed in said body and communicating with said nozzle, said suction passage terminating in a rearwardly facing outlet opening, surface engaging supporting wheel means at the rear of said body, means pivotally connecting said wheel means to said body rearwardly of its center of gravity, said body forwardly of said pivotal connecting means being otherwise unsupported whereby said nozzle is free to drop and rest upon the surface to be cleaned and thereby be vertically adjustable in accordance with the type of surface being cleaned, a thrust receiving shaft having surface engaging thrust receiving wheels, a propelling handle attached to said shaft for transferring propelling forces thereto, elongated slot means on said body receiving said shaft for displacement of said thrust receiving wheels relative to said body upon application of propelling forces to said handle when cleaning a surface having a yieldable pile, and a portion of said slot means engageable with said shaft to limit the upward movement of said nozzle and provide an abutment for transferring said handle forces to said body and thus to said nozzle
  • said elongated slot means includes an elongated opening having an upwardly and rearwardly inclined wall arranged with respect to said shaft to receive thrust components of the forces applied to said shaft in applying pulling and pushing forces to said handle to thereby raise said nozzle about said pivotal connecting means.
