Definitions

  • This invention relates to handheld floor sweepers and more particularly to a hand- held floor sweeper having a plurality of sweeping brushes with a dust storage compartment having a drop-down tray.
  • This invention is directed to a push button release that releases the drop-down tray.
  • Handheld sweepers have been used in the past to pick up dust and small items from hard surfaces, such as wood or tile floors, and carpets having varying piles of various heights.
  • One type of handheld floor sweeper that has been used extensively in the past is a manually pushed floor sweeper that is not powered by a motor.
  • the handheld sweeper has brushes mounted on a shaft located in the sweeper head that contact the surface to be cleaned. The brushes rotate as the sweeper is pushed and pulled across the floor surface. The brushes rotate and the bristles sweep the loose material up into a dust tray, canister or similar dust-receiving portion in the sweeper head.
  • the invention disclosed herein is used with a hand-held floor sweeper, which is extremely light and has a very low profile sweeper head.
  • the floor sweeper head is mounted to an elongated handle by means of a universal pivot or universal joint that allows the handle to rotate 360° about the universal pivot that is mounted on the sweeper head. This allows the floor sweeper head to easily pivot about the handle in any direction for easily picking up loose materials under over hanging cabinets or under furniture.
  • the brushes provide cleaning action in any direction to sweep the dust and particles into the dust storage compartment. One of the brushes drive the other brushes to direct the dust or loose material into the dust-receiving compartment in the sweeper head.
  • the sweeper head generally lies in a horizontal plane with the elongated handle extending upward from the sweeper head.
  • the invention provides for a storage compartment having a flat horizontally disposed floor. With the simple push of a button, the flat floor of the storage compartment drops down and the dust and debris stored in the compartment can be disposed in a garbage container. This allows the dust and debris to be disposed of from the storage compartment with the user not having to touch the debris.
  • a handheld floor sweeper adapted for movement over a surface and clean debris from that surface by brushing, the sweeper comprising:
  • the operating lever may be mounted to the sweeper body by means of a second pivot connection allowing the operating lever to rotate about the second pivot connection.
  • the operating lever may have a top portion above the second pivot connection and a bottom portion below the second pivot connection, the bottom portion having a retaining finger to engage the latch.
  • the sweeper may further comprise a spring mounted between the sweeper body and the top portion of the operating lever to apply a force to the top portion of the operating lever when the operating lever is depressed.
  • the sweeper may further comprise a complimentary finger on the latch for engaging the retaining finger on the operating lever on a latching engagement in a first latching position and the retaining finger releasing the complimentary finger when the top portion of the operating lever is depressed.
  • At least one of the complimentary finger or retainer finger may have a curved surface whereby when the bottom tray is pushed from its open position to the closed position, the complimentary finger provides a force to the retainer finger to pivot the bottom portion of the operating lever away from the sweeper body thereby allowing the complimentary finger to pass over the retainer finger.
  • a handheld floor sweeper adapted for movement over a surface and clean debris from that surface by brushing, the sweeper having:
  • the operating lever may have a top portion above the second pivot connection and a bottom portion below the second pivot connection, the bottom portion having a retaining finger to engage the latch.
  • the sweeper may further comprise a spring mounted between the sweeper body and the top portion of the operating lever to apply a force to the top portion of the operating lever when the operating lever is depressed.
  • the sweeper may further comprise a complimentary finger on the latch for engaging the retaining finger on the operating lever on a latching engagement in a first latching position and the retaining finger releasing the complimentary finger when the top portion of the operating lever is depressed.
  • At least one of the complimentary finger or retainer finger may have a curved surface whereby when the bottom tray is pushed from its open position to the closed position, the complimentary finger provides a force to the retainer finger to pivot the bottom portion of the operating lever away from the sweeper body thereby allowing the complimentary finger to pass over the retainer finger.
  • Fig. 1 illustrates a handheld sweeper 10 having an elongated handle or shaft 12.
  • the handle 12 has an upper end and a lower end 14 attached by means of a universal pivot or universal joint 16 to a sweeper body 18.
  • the sweeper body 18 contains several brushes 20, and a drive mechanism to rotate the brushes 20 to pick up dust and debris on the floor.
  • the sweeper body 18 normally assumes a substantially horizontal plane when sweeping a floor or similar surface.
  • a dust and debris storage compartment 22 Inside the sweeper body 18 is a dust and debris storage compartment 22. As the sweeper 10 is pushed and pulled along the floor, the sweeper brushes 20 rotate to pick up and propel the dust and debris into the dust storage compartment 22.
  • the dust storage compartment 22 is best illustrated in Figs. 4-8 .
  • the dust storage compartment 22 is formed by side walls 23 and a drop-down dust tray 24 that functions as the bottom cover of the dust storage compartment 22.
  • the drop-down dust tray 24 is connected by a pivot connection 26 to the sweeper body 18 at a forward end of the dust storage compartment 22.
  • One or more pivot points and connections can be utilized so long as it provides a suitable pivot connection about which the drop-down dust tray 24 can pivot from an open to a closed position.
  • Fig. 3 illustrated the bottom view of the sweeper 10 with the drop-down dust tray 24 in the closed and latched position.
  • Fig. 4 is a bottom perspective view illustrating the drop-down dust tray 24 in the open or dropped down position. The drop-down dust tray 24 is seen pivoted to the open position about the pivot connection 26. At a rear end 25 of the drop-down dust tray 24 is a latching member 32.
  • a push button operating mechanism 29 operates the latching and release of the drop-down dust tray 24.
  • a push button operating lever 30 that is mounted to the sweeper body 18 by means of a pivot connection or pivot bar 31.
  • the pushbutton operating lever has a top portion above the pivot bar 31 and a lower portion below the pivot bar 31.
  • the push button operating lever 30 is free to pivot about the pivot connection 31 when a force is applied to the top of the operating lever 30 as seen by the arrow "A" in Fig. 6 .
  • a spring 33 provides a counter force against the push button operating lever 30 so the force applied at "A" must be sufficient to overcome the spring force so that the operating lever 30 will move from the latched position of Fig. 5 to the unlatched position in Fig. 6 .
  • the bottom of the pushbutton operating lever 30 has a curved foot 36. This engages in a latching condition the latching member 32 at the rear end 25 of the drop-down dust tray 24 as seen in Fig. 5 .
  • the user applies the force "A" to the top of the operating lever 30 as described above.
  • the operating lever 30 pivots about pivot connection 31 and the curvet foot 36 pivots away from the latching member 32. This releases the latching member 32 from engagement with the curved foot 36.
  • the rear end 25 of the drop-down dust tray 24 will drop down in the direction of arrow "B" due to gravity as the drop-down dust tray 24 pivots about the pivot connection 26.
  • the force "A" is removed from the operating lever 30, the operating lever 30 is pushed back to its original position by the spring 33 as illustrated in Fig. 7 .
  • the user pushes the drop-down dust tray 24 upward in the direction of arrow C as illustrated in Fig. 8 .
  • the latching member 32 engages the curved foot 36 of the operating lever 30, applying a force to the curved foot 36 in the direction of arrow D.
  • This causes the operating lever 30 to move in the direction of arrow D.
  • the force is sufficient to overcome the force of spring 33.
  • the operating lever 30 pivots about pivot pin 31 a sufficient amount to allow the latching member 32 to pass over the end of the curved foot 36.
  • the spring 33 pushes against the top of the operating lever 30 so that the pushbutton returns to its original position as seen in Fig. 5 .
  • the drop-down dust tray 24 then assumes the original closed and latched position illustrated in Fig. 5 .
  • latching members may be used as long as they serve the purpose of latching the drop-down dust tray 24 to a closed position and can be released by the user merely pushing a release button so that the user does not come into contact with the debris in the dust storage compartment.
