The present invention relates to waste receptacles, more specifically to a dustpan for consumer and business floor cleanliness.
Sweeping the floor with a brush or broom has been an essential part of cleaning since the dawn of civilization. The broom is usually used to accumulate debris and dust in one place. Thereafter, many different types of devices have been used throughout history to dispose of the accumulated debris. A dustpan is one of the devices in recent history that has proven to be very useful in receiving and transporting the accumulated debris from the floor to the waste receptacle.
One well-known type of dustpan is of the upright type. The basic components of an upright dustpan are a long handle and a main body to receive the accumulated debris from the floor. The upright dustpan with pivoting main body has an added benefit of keeping the debris contained in the container and thus keeping it from spilling unintentionally. Moreover, it promotes smaller foot-print to save storage space and hides the debris deep in the container. Some dustpans also have a lid that closes when pivoted for storage purposes to contain the odor of the debris and keep insects away.
In most upright dustpans the main body connects to the handle via a pivotal joint and has a single opening for collecting and disposing of the debris. The dustpan's main body rotation about the pivot is free form resulting in uncontrolled rotation of the main body in different orientations. The uncontrolled motion of the main body requires using both hands to control the motion of the main body when disposing the debris and dust into the waste receptacle. For instance, in a biohazard area, it is of primary importance to minimize risk of direct exposure to any kind of debris; however, the use of second hand to dispose debris from the dustpan pose a serious threat of exposure as its touching the contaminated areas of the dustpan. The main disadvantage of these upright dustpans is that they require user's both hands to control the rotation of the main body for the disposal of debris.
Few upright dustpans in prior art have a trap door that is actuated by trigger on the long handle. This type of upright dustpan uses complex mechanisms involving cables, pulleys, etc. which also results in complex manufacturing practices and higher costs. Many times, in household, public or business settings, waste receptacles have a small opening which does not allow room for the dustpan to practice free form maneuverability which results in either debris falling out of the waste receptacle or dustpan getting stuck in the waste receptacle.
The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the more detailed description that is presented later.
The present disclosure relates to an upright dustpan comprising an elongated handle and a main body/collecting pan with a hinged back door that can be actuated in a hands-free way via a trigger located on the collecting pan. The trigger can be actuated by the edge of the waste receptacle or any rigged body thus making it hands free for the user.
The foregoing has outlined rather broadly the more pertinent and important features of the present disclosure so that the detailed description of the invention that follows may be better understood and so that the present contribution to the art can be more fully appreciated. Additional features of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and the disclosed specific methods and structures may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present disclosure. It should be realized by those skilled in the art that such equivalent structures do not depart from the spirit and scope of the invention as set forth in the appended claims.
Other features and advantages of the present invention will become apparent when the following detailed description is read in conjunction with the accompanying drawings, in which:
The following description is provided to enable any person skilled in the art to make and use the invention and sets forth the best modes contemplated by the inventor of carrying out his invention. Various modifications, however, will remain readily apparent to those skilled in the art, since the general principles of the present invention have been defined herein to specifically provide an innovative upright dustpan.
Referring now to the drawings,
The main body (24) is connected to a long handle (12) via two wires (1), which are pivotally connected to the respective side wall (3), (9) of the main body (24) at holes (2) and (10) so that the main body/collecting pan (24) can freely pivot relative to the handle (12). When the main body/collecting pan (24) is lifted above the floor, the main body/collecting pan rotates to an upright position as shown in
The back door (5) of the main body/collecting pan is connected to the bottom face (11) by a piano hinge (4). The back door (5) is movable between a closed position for containing dust and debris inside the collecting compartment (26) an open position for dumping the contents of the collecting compartment into a waste bin. A releasable latching mechanism (7) holds the back door (5) in a closed position until the latching mechanism (7) is actuated. One aspect of the present disclosure is the ability to release the latching mechanism (7) in a hands-free manner, i.e., without requiring the use of hands to release the latch.
It is to be noted here that the latching mechanism (7) is not restricted to the type shown in
During normal use, the main body/collecting pan (24) will lay flat on the floor with bottom surface (11) resting on the ground plane.
When the main body (24) is lifted off the floor, the main body (24) pivots to an upright position as shown in
Although the invention has been described in considerable detail in language specific to structural features, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific features described. Rather, the specific features are disclosed as exemplary preferred forms of implementing the claimed invention. Stated otherwise, it is to be understood that the phraseology and terminology employed herein, as well as the abstract, are for the purpose of description and should not be regarded as limiting. Therefore, while exemplary illustrative embodiments of the invention have been described, numerous variations and alternative embodiments will occur to those skilled in the art. Such variations and alternate embodiments are contemplated, and can be made without departing from the spirit and scope of the invention.
It should further be noted that throughout the entire disclosure, the labels such as left, right, front, back, top, bottom, forward, reverse, clockwise, counter clockwise, up, down, or other similar terms such as upper, lower, aft, fore, vertical, horizontal, oblique, proximal, distal, parallel, perpendicular, transverse, longitudinal, etc. have been used for convenience purposes only and are not intended to imply any particular fixed direction or orientation. Instead, they are used to reflect relative locations and/or directions/orientations between various portions of an object.
In addition, reference to “first,” “second,” “third,” and etc. members throughout the disclosure (and in particular, claims) are not used to show a serial or numerical limitation but instead are used to distinguish or identify the various members of the group.
The present application claims priority to 62/898,292, filed on Sep. 10, 2019 entitled “Innovative Upright Dustpan”, the disclosure of which is hereby incorporated in its entirety at least by reference.
