Abstract:
A dustpan apparatus, comprising:a. a debris receiving member having an enclosed wide body for receiving and retaining debris therein, the enclosed wide body having a front lip and a first retaining means remote from the front lip;b. a pivotable bracket movably connected at opposite sides of said enclosed wide body and having a threaded shaft integrally formed thereto and centrally located, the pivotable bracket further having a latching means integrally formed thereto for latching to said first retaining means of said enclosed wide body to immobilize the pivotable bracket from moving, where the threaded shaft is located in a vertical direction;c. a quick release adaptor having a generally cylindrical shaped body, the cylindrical shaped body having a proximal portion with a proximal open end, a distal portion with a distal open end, a central bore extending from the proximal open end through the distal open end, and a side slot interconnecting the central bore and located on the proximal portion, where the central bore receives said threaded shaft of said pivotable bracket in the proximal portion of the quick release adaptor;d. a pawl pivotally mounted in said side slot of said cylindrical shaped body of said adaptor and having a tip with inner screw threads;e. a coil spring being installed in said side slot of said cylindrical shaped body of said adaptor and biasing said tip of said pawl for engaging said tip of said pawl to said threaded shaft of said pivotable bracket;f. a thin partition disposed between said central bore and said side slot to partially divide them, so that said side slot is partially connected with said central bore;g. said thin partition having an outward facing recess for adapting to one end of said coil spring;h. said pawl having an inward facing recess located remote from said tip for adapting to the other end of said coil spring;i. said cylindrical shaped body of said adaptor rotatable on said threaded shaft of said pivotable bracket such that said inner screw threads on said pawl threadedly engage with said threaded shaft of said pivotable bracket; andj. an elongated handle member detachably attached to said quick release adaptor from said distal open end and secured thereto by a second retaining means;k. whereby when said pawl is biased by said coil spring, said tip is engagable with said threaded shaft of said pivotable bracket such that said cylindrical shaped body of said adaptor is lockable on said threaded shaft for preventing said adaptor from sliding out from said threaded shaft, and said cylindrical shaped body of said adaptor is further threadable on said threaded shaft to precisely adjust the tightness of said cylindrical shaped body of said adaptor, and when said pawl is pressed against said coil spring, said tip is disengagable from said threaded shaft and said cylindrical shaped body of said adaptor is unlocked and is slidable out from said threaded shaft for quick release.
