  • suction cleaners of the type utilizing disposable dirt-collecting bags.
  • an operator wished to dispose of a dirt- ;collecting bag he had to grasp the bag, remove it from the suction cleaner and carry it to its place of disposal.
  • a dirt-collecting bag is sup ported by a removable body member of a suction cleaner for convenient insertion and removal therefrom. An operator can remove a dirt-collecting bag from a suction cleaner equipped with the instant invention and dispose of it without coming into contact with the bag.
  • the removable body member has a mounting tube for supporting and retaining a dirt-collecting bag thereon.
  • the removable body member is further pro vided with a releasable bag-engaging device and actuating means for releasing the device to permit a bag to be removed from the mounting tube.

  • FIGS. 1 and 2 disclose a suction cleaner 10 of the type embodying the instant invention.
  • the suction cleaner 10 has a suction creating motor fan unit 12 located in one portion thereof.
  • the motor fan unit 12 is separated from the dirtcollecting area 14 by a secondary filter 16.
  • the secondary filter 16 has a removable dirt-collecting membrane 18 which catches any dust or dirt particles not trapped inside of the disposable dirt-collecting bag 46 located in the dust-collecting area 14.
  • the membrane I8 acts as a double barrier to prevent dust or dirt from entering the motor fan unit 12.
  • a flexible hose is normally connected to the aperture 20 formed in a body end member 22 which member is detachably affixed to the suction cleaner 10.
  • the motor fan unit 12 creates a sub-atmospheric pressure in the dirt-collecting area 14 and hence in the hose normally in communication therewith. Dirt and other particles sucked up by the hose are deposited in the disposable dirt-collecting bag 46 in the dirt collecting area 14. Air that enters the dirt-collecting bag 46 passes through the porous walls thereof, through the secondary filter membrane 18 and enters the motor fan unit 12. Air exiting from the motor fan unit 12 leaves the interior of the suction cleaner 10 through a series of openings 23 formed in the top surface thereof. The path of air flowing through the suction cleaner 10 is shown by the arrows in FIG. 2.
  • the body end member 22 adjacent the dirt-collecting area 14 is secured to the suction cleaner 10 by having the outward projection 24 of its top wall 26 abut the inside portion 28 of a down Ward projection 30 of the suction cleaner top wall 32.
  • the bottom portion of body end member 22 is secured to the suction cleaner 10 by means of an over-center clasp 34, one end of which engages the body end member 22 through an aperture 36 formed in the bottom surface thereof.
  • the opposite end of the clasp 34 is se cured to the bottom of the suction cleaner.
  • a resilient sealing strip 38 is placed around the outside perimeter of the inner wall 40 of the body end member 22 to provide an airtight seal between the body end member 22 and a transverse wall 42 of the suction cleaner l0 abutted by the body end member 22.
  • the body end member 22 has a bag-supporting mounting tube 44 projecting from its inner wall 40 toward the dirtcollecting area 14.
  • the mounting tube 44 is aligned with the aperture 20 in the body end member 22.
  • a bag 46 is positioned on the mounting tube 44 by pushing the tube 44 through an aperture 48 in the bag collar 50.
  • the mounting tube 44 is tapered with its larger diameter portion 52 adjacent the inner wall 40 of the body end member 22.
  • the small diameter portion 54 of the mounting tube 44 is sized so as to be freely receivable in the bag collar aperture 48.
  • the larger diameter portion 52 is proportioned to wedge within the bag collar aperture 48 as shown in FIGS. 4 and 5.
  • a pair of projections 56 adjacent the small diameter portion 54 of mounting tube 44, are made to protrude transversely of and radially outward from the tube 44.
  • the projections 56 protrude sufficiently to engage the inside wall 58 of the bag collar 50 and prevent the bag 46 from slipping off of the mounting tube 44.
  • the bag collar 50 is normally securely wedged on the mounting tube 44 and would not slide down the tube to engage the projections 56.
  • the weight of the dirt in the bag 46 may cause the bag collar 50 to slide down the mounting tube 44 when the body end member 22 is removed from the suction cleaner 10, to dispose of the dirt bag 46.
  • the bag 46 and body end member 22 are shown detached from the suction cleaner in FIG. 9.
  • the solid lines show the bag collar 50 wedged on the mounting tube 44.
  • the dashed lines show the bag collar supported by the projections 56.
  • the projections 56 are formed at the ends of a pair of leaf springs 64 which are mounted on the inside of the mounting tube 44 and extend in a parallel direction therein.
  • a pair of rivets 61 secure the leaf springs 64 to the mounting tube 44.
  • the projections 56 have cam surfaces 60 with a base 62 adjacent the free end of the mounting tube and located within the small diameter portion 54 of the mounting tube 44.
  • the purpose of the cam surfaces 60 is to allow a bag collar 50 to be pushed onto the mounting tube 44 even though the projections 56 are protruding beyond the outside diameter of the mounting tube 44 so as to enable the projections 56 to engage the inside wall 58 of the bag collar 50 once the latter is situated between the projections 56 and the inside wall 40 of the body end member 22.
  • the bag collar 50 When a bag collar 50 is pushed onto the mounting tube 44 and the projections 56 are protruding, the bag collar 50 first passes over the base 62 of the cam surfaces 60 and then rides therealong, thus biasing the projections 56 radially inwardly toward the interior of the mounting tube 44. After the bag collar 50 has passed over the projections 56, the leaf springs 64 cause the projections 56 to return to the position they occupied immediately before the bag collar passed thereover.
  • the projections 56 When it is desired to remove the bag 46 from the mounting tube 44, such as when an operator has removed the body end member 22 from the suction cleaner to dispose of the dirt-filled bag 46, the projections 56 must be retracted inside of the mounting tube 44 to allow the bag collar 50 to pass over the projections 56.
  • an operator need only push in wardly on the actuator button 66 which projects into the outside surface of the body end member. This movement of the actuator button 66 causes an actuator bar 68, having a pair of parallel arms 70 connected by cross bar 74, to be moved inwardly.
  • a pair of springs 72 mounted between the inner wall 40 and the actuator button 66 biases the latter outwardly.
  • the cross bar 74 engages slots located approximately at the midpoint of a pair of parallel ejector arms 76.
  • the ejector arms 76 are connected by a support 78 extending therebetween.
  • the ejector arms 76 are suspended from the inner wall 40 of the body end member 22 by being pivotally connected at their upper portions to a pivot shaft 80.
  • the pivot shaft 80 is affixed to the inner Wall 40 by means of a pair of brackets 79.
  • Movement of the actuator bar 68 inwardly causes the ejector arms 76 to be pivoted about the pivot shaft 80.
  • a tab 82 bent away from the mounting tube 44, is formed at the lower portion of each of the ejector arms 76.
  • the bent tabs 82 are adjacent to, but do not engage, pins 84 which project through apertures 87 in the mounting tube 44.
  • the pins 84 are connected to the leaf springs 64 adjacent their midpoint. When the pins 84 are biased inwardly toward the center of the mounting tube 44, the leaf springs 64 are forced to bend inwardly toward the center of the mounting tube 44.
  • the pins 84 are pushed inwardly by the lower portion 83 of the ejector arms 76 adjacent the tabs 82 when the ejector arms 76 pivot about the pivot shaft 80. Pivotal movement of the ejector arms 76 is stopped when the lower portion 83 thereof fully engages the pins 84.
  • the ejector arms 76 are rendered inoperative when the body end member 22 is positioned on the suction cleaner 10 for operation of the latter, by means of ribs 86 located in the top portion of the suction cleaner 10. The ribs are closely adjacent the top surfaces 88 of the ejector arms 76. If the actuator button 66 is moved inwardly, the ejector arms 76 will move only a short distance before striking the ribs 86.
  • Rendering the ejector arms 76 inoperative when the body end member 22 is positioned on the suction cleaner 10 is desirable as it prevents the projections 56, which insure that the bag collar 50 will not slip off the end of the mounting tube 44, from being moved inside the mounting tube 44 and hence being made ineffective. Furthermore, the body end member 22 cannot be positioned on the suction cleaner 10 when the actuator button 66 is depressed and the ejector arms 76 are rotated about pivot shaft 80, since the ribs 86 and the ejector arms 76 interfere to prevent the body end member 22 from properly locating within the suction cleaner.
  • Pressing the ejector button 66 causes the ejector arms 76 and cross bar 74 to be moved inwardly.
  • the cross bar 74 is connected to the ejector arms 76.
  • the ejector arms 76 pivot about a shaft 80.
  • the lower portion 83 of the ejector arms 76 engages the pins 84 affixed to the leaf springs 64.
  • the projections 56 of the leaf spring 64 are moved to a positon within the mounting tube 44. This position of the projections 56 permits a bag collar to slide over the projections 56 without interference, thus allowing the bag 46 to drop from the body end member.
  • the operator merely pushes the bag collar 50 over the end of the mounting tube 44. If the actuator button is not in its depressed position when the bag is pushed on the mounting tube, the bag collar will simply momentarily bias the projections inwardly as it passes over the cam surface 60.
  • the button If the button is in its depressed position when the bag collar is pushed on the mounting tube, the bag collar will not engage the projections. However, as the bag collar is moved up the mounting tube, it will engage the ejector arms. Further movement of the bag on the mounting tube will cause the ejector arms to pivot about the shaft 80 and cause the cross bar 74 and the parallel arms 70 to be moved outwardly. As the arms 70 are moved outwardly, the actuator button 66 will return to its original position.
