Conventional brooms have uniform length bristles that contact the floor while sweeping. While the bristles can be pressed against the floor, most bristles contact the floor at an angle such that a lateral surface of each bristle, especially those that are bent, rather than and end of the bristle, sweeps against the floor as the broom is moved. Moreover, when sweeping, almost half of the bristles fail to touch or impact the dirt or debris being swept and only touch air while sweeping.
Additionally, conventional dustpans require a user to bend over or kneel to reach the dustpan while collecting swept dirt and debris. Most users also hold the dustpan at an angle that biases the edge of the collection area against the floor to facilitate swiping of dirt and debris into the dustpan. Such use requires the user to bend and stress their body, which may be uncomfortable for some users.
One solution that has been proposed in the past to address potential challenges with using a waste receptacle such as a dustpan can be seen in U.S. Pat. No. 8,875,339 to Dobson. Dobson describes a dustpan that includes a blade (20, FIG. 1) that is pressed against the floor, as shown in
The invention provides a system including a step-on dustpan configured to include a step-on portion, a handle, a lip, a handle clip, a pan surface and side panels. The system also includes a broom configured to include a broom handle, a broom block and beveled bristles. The beveled bristles are disposed in the broom block to form a v-shape in a transverse direction with respect to the broom block. When the step-on portion is engaged by a user, the lip is configured to form a seal against a floor surface.
In one aspect, the present disclosure describes a dustpan that includes a receptacle, which is enclosed on four sides by a bottom pan, two sidewalls and a back panel, and includes a lip at a free end of the bottom pan opposite the back panel. The dustpan further includes a handle connected to the back panel and extending opposite the receptacle. The handle has a curved shape that terminates at a floor pad. The dustpan is configured to only contact a flat floor surface along the floor pad and the lip when in an at-rest position. The dustpan further includes at least one foot disposed on an exterior surface of the receptacle. A step-on portion is defined on the handle and is angled with respect to the flat floor surface and configured to provide a pedal for a user to apply a force. When the force is applied to the pedal, the dust pan transitions from the at-rest position to an operating position in which the handle deforms to permit the at least one foot to further contact the flat floor surface and to decrease an angle between the lip and the flat floor surface.
In another aspect, the disclosure describes a broom having an elongate handle having a first end and a second end. A broom block is connected to the first end of the elongate handle, and a first plurality of bristles is connected to a first section of the broom block. The first plurality of bristles defines a broom head, which has a sweeping end. The sweeping end includes two planar sections, each having an elongate shape, wherein the two planar sections are disposed at an angle relative to one another and intersect a bottom edge to define a bevel along the sweeping end of the broom head.
In yet another aspect, the disclosure describes a cleaning system that includes a broom and a dustpan. The broom has an elongate handle and a broom block connected at one end of the elongate handle. The broom head comprises a first plurality of bristles connected to the broom block, which define a broom head having a sweeping end opposite the broom block. The sweeping end includes two planar sections disposed at an angle relative to one another to define a bevel. The dustpan has a receptacle connected to a handle, which includes a cylindrical channel with locking nubs that is releasably attachable to the elongate handle of the broom. The handle further includes a floor pad opposite its connection to the receptacle, and a lip disposed opposite its connection to the handle such that, when the dustpan is detached from the broom and sits on a flat floor surface in an at-rest position, the dustpan contacts the flat floor surface only along the floor pad and the lip, and remaining portions of the handle and receptacle are suspended above the flat floor surface.
Reference will now be made in detail to specific embodiments or features, examples of which are illustrated in the accompanying drawings. Wherever possible, corresponding or similar reference numbers will be used throughout the drawings to refer to the same or corresponding parts. Moreover, references to various elements described herein, are made collectively or individually when there may be more than one element of the same type. However, such references are merely exemplary in nature. It may be noted that any reference to elements in the singular may also be construed to relate to the plural and vice versa without limiting the scope of the disclosure to the exact number or type of such elements unless set forth explicitly in the appended claims.
The present disclosure is directed to a floor cleaning system that includes a step-on dustpan 100 and beveled broom 300 combination. The combination of the step-on dustpan 100 and the beveled broom 300 provides an effective and more efficient system to collect floor debris than traditional broom and dustpan combinations in that the dustpan can be used on uneven or unclean surfaces while still maintaining ease of use and a good seal at the blade of the dustbin. Further, cleaning effectiveness of the floor cleaning system is improved by providing beveled bristles on the broom, which increases contact area between the broom and the floor and, also, the ability of the broom to push debris past the blade of the dustbin and into the collection cavity of the dustpan. In certain embodiments, the step-on dustpan 100 includes a hands-free feature to assist a user in debris collection without the user bending or kneeling when in use.
Referring now to
The floor pad 137 contact with the floor is configured to hold the dustpan 100 in place when a user steps onto the step-on portion 136. A force, F, applied by the user while stepping onto the step-on portion 136 is disposed at an angle, gamma-sub-alpha (γα), as shown in
The dustpan 100 further includes a pan or debris receptacle 111 that is closed on four sides and open on two sides. The receptacle 111 is defined between a bottom pan surface 110, two side panels 115 and a back panel 116. The bottom pan surface 110 includes a lip or blade 105 along its leading edge opposite the back panel 116 that contacts the floor and has a triangular or beveled edge that terminates in a line edge 113 to facilitate the sweeping of debris into the receptacle 111.
In some embodiments, the action by a user of stepping on the handle step-on portion 136 of the dustpan 100 applies the force F, which causes various other forces to be applied at various locations tending to bias certain portions of the dustpan 100 against the floor and also deform the handle body portion 130 in a direction tending to straighten the handle. More specifically, and as shown in
Bending of the dustpan 100 in this way augments the biasing force that pushes the lip 105 against a floor 145 and an angle, alpha (α) between the lip 105 and the floor 145 to decrease, which facilitates entry of debris into the receptacle 111 and also provides a better seal against dust or debris passing under the lip 105 rather than into the receptacle 111 when swept in past the line edge 113. In this position, the bottom surface of the receptacle may be at an angle of 3 to 5 degrees relative to the floor, which can be reduced to zero when the user steps on the step-on portion 136 and applies a downward force. As can be appreciated, any other angle can also be used. At the lip 105, the angle α will also assume an inclination when the dustpan is at an at-rest condition, and reduce while the user pushes down on the step-on portion 136. In some embodiments, the lip 105 is disposed within or integral to a pan entry lip portion 107 (
As can be seen in
In some embodiments, the dustpan 100 comprises a large cleaning comb 120 for removing hair from the broom 300 shown in
The body 130 of the handle 135 further includes a handle clip 125, which in the illustrated embodiment is shown as a channel extending at least partially along a middle portion of the body 130. The channel 125 is defined between two ribs 124 (shown in
