Definitions

  • the present invention relates to a dustpan and broom housing assembly for ease of debris disposal.
  • dustpans e.g., dirt, dust, leaves, and other debris or fragmented materials
  • a surface such as a floor
  • dustpans Various designs have been utilized over the years for making and using dustpans. For example, different designs may utilize one piece or multiple piece constructions, may employ metallic, plastic and/or molded materials, and may show numerous ornamental variations.
  • One common design for dustpans consists of a shallow dustpan body with an open edge or "blade" at the front of the dustpan body, and an elongated pedal or grip attached to the rear of the dustpan body.
  • a pedal extends outwardly from the rear of the dustpan body in a generally parallel or slightly angled direction relative to the surface when the dustpan is placed on the surface.
  • the pedal thus provides a handy and convenient means for manipulating the dustpan during use.
  • such dustpans do not always effectively keep the entire length of the front edge or blade of the dustpan in contact with the surface during use.
  • at least a portion of the various materials intended to be swept into such dustpans may be swept underneath the dustpan (or blocked altogether) instead of into the body of the dustpan.
  • Brooms are used to sweep materials into dustpans.
  • current boom designs have no means of lifting a dustpan. Instead, users must use both hands - one hand to hold the broom handle coupled to the broom housing assembly and one hand to hold the dustpan, and then bend over to lift the dustpan and/or tilt it into a collecting receptacle. This may be difficult for elderly or physically restricted people.
  • conventional broom and dustpan systems are limited and it necessitates a better solution to make removal of materials faster, more effortless and convenient for users.
  • the present invention is directed toward a dustpan and broom housing assembly combination usable for ergonomic and efficient removal of materials from a surface, while standing in an upright position, without the need to bend over and pick up the dustpan.
  • the dustpan includes a body, a blade, a rear support, a cross member, and a connector.
  • the broom housing assembly includes a socket, a center member, a side member, a rear member, a head support, and apertures.
  • the dustpan and broom housing assembly combination includes a means of coupling the broom housing to a pole-like broom handle and a means for coupling the broom housing assembly to the dustpan.
  • the dustpan includes: a body, and a cross member coupled to the body, and means, disposed on the cross member, for detachably coupling the dustpan to a broom.
  • the means for detachably coupling includes a plurality of connectors.
  • each of the plurality of connectors includes a mushroom shaped head and a stem.
  • each of the plurality of connectors are disposed on opposing ends of the cross member.
  • the dustpan includes a plurality of connectors that are integrally formed with the cross member.
  • the dustpan a plurality of connectors are formed as separate structures from the cross member.
  • the dustpan includes the means for detachably coupling via an adhesive coating.
  • the dustpan in another embodiment, includes the means for detachably coupling via a magnet.
  • a broom in an embodiment, includes a socket, a body coupled to the socket, and a bristle array coupled to the body; and a means, disposed on the body, for detachably coupling the body to a dustpan.
  • the broom includes the means for detachably coupling comprising a plurality of apertures. More specifically, each of the apertures includes a circular portion and a slot portion.
  • the broom includes a plurality of apertures disposed on a portion of the body adj acent to the bristle array.
  • the broom includes the means for detachably coupling via an adhesive coating.
  • the broom includes the means for detachably coupling via a magnet.
  • a broom and dustpan system includes a dustpan, a broom, and a means for detachably coupling the dustpan and the broom together.
  • the system includes the means for detachably coupling the dustpan and the broom together comprising a plurality of connectors and a plurality of apertures.
  • each of the plurality of connectors include a mushroom shaped head and a stem
  • each of the apertures include a circular portion and a slot portion
  • the system includes the means for detachably coupling the dustpan and the broom together comprising one or more adhesive coatings.

  • the dustpan 10 maintains contact with the surface 24 at two spaced apart areas of the dustpan 10, i.e. the blade 20 and the rear support 22, at all times during use of the dustpan 10.
  • the blade 20 can constitute and/or include the forward most portion of the dustpan 10.
  • the rear support 22 can constitute and/or include the rearward most portion of the dustpan 10.
  • the user can apply downward pressure (toward the surface 24) on the dustpan 10 between the rear support 22 and the blade 20 (with the user's foot, for example), e.g., near the rear support 22, which thereby causes the blade 20 to press more firmly downward against the surface 24 to be cleaned.
  • downward pressure on the dustpan 10 moves the dustpan 10 from a resting position (e.g., as illustrated in FIG. 5 and FIG. 6 and a depressed position (e.g., as illustrated in FIG. 7).
  • the downward pressure can be applied to the raised pedal 14 or either of the side members 16 to move the dustpan 10 from the resting position to the depressed position.
