Abstract
A dustpan includes an open-front receptacle, at least one elongated rail on the receptacle, an elongated handle having a coupling portion, and a coupling mechanism slidably coupled to the at least one rail and pivotally coupled to the coupling portion of the handle so that the handle is both slidably and pivotally moveable relative to the receptacle between use and storage positions. A broom includes an elongated second handle and a head carrying set of bristles, the head having a housing with curved side portions shaped and dimensioned to respectively nest in recesses in the dustpan handle in a stowed condition clipped to the dustpan handle in such a way that it does not interfere with the pivoting and sliding movement of the dustpan handle. The dustpan receptacle can be stood on its flat rear end wall with the stowed broom received therein.
Description




BACKGROUND




This application relates to devices for use in cleaning floors and, specifically, to tools or utensils for sweeping. The application relates in particular to dustpan and broom combinations.




Dustpans, brooms and combinations thereof have long been provided. Indeed, it has long been known to have dustpans with long handles so that they can be operated while the user is in an upright or standing position, as well as to have arrangements wherein the handles of the broom and dustpan can be clipped together for storage. In particular, arrangements have been provided wherein the broom head and/or bristles are stored within the dustpan receptacle when not in use.




However, heretofore, such combinations have required that the handles of the dustpan and broom be separated from each other in order to withdraw the broom bristles from the dustpan receptacle. Dustpans with pivoting handles have also been provided but, heretofore, they have not been capable of pivoting movement while the broom handle is connected thereto. Also, while it is known to provide dustpans with pivoting handles which can be latched in different positions, the movement to and from a latched condition has heretofore required the use of two hands, with one had to operate the dustpan handle and another to operate a latch mechanism, for example.




SUMMARY




There is disclosed in this application a dustpan/broom combination which avoids the disadvantages of prior arrangements, while affording additional structural and operating advantages. An important aspect is the provision of a dustpan with a long pivoting handle which can be easily moved between use and storage conditions with a single hand.




Another aspect is the provision of a dustpan and broom combination, wherein the broom is connectable to the dustpan handle and is moveable therewith between the various conditions of the dustpan handle.




Another aspect of the provision of a combination of the type set forth, which is a relatively simple and economical construction.




Certain ones of these and other aspects may be attained by providing a dustpan comprising an open-front receptacle, at least one elongated rail on the receptacle, an elongated handle having a coupling portion, and coupling mechanism slidably coupled to the at least one rail and pivotally coupled to the coupling portion of the handle so that the handle is both slidably and pivotally movable relative to the receptacle.

DETAILED DESCRIPTION




Referring to

FIGS. 1-3

, there is illustrated a combination, generally designated by the numeral


10


, including a dustpan


20


and a broom


70


. Referring also to

FIGS. 6 and 8

, the dustpan


20


includes an open-front receptacle


21


including a substantially flat rear end wall


22


, integral along three sides thereof with a forwardly projecting peripheral wall structure


23


including opposed side walls


24


and


25


and a top wall


26


. The side walls


24


and


25


may diverge slightly forwardly and may be slightly convex, as viewed from the outside thereof and respectively have downwardly and forwardly sloping upper front edges


27


. The top wall


26


may also be slightly convex, as viewed from the outside, and has a concavely curved front edge


28


which is continuous with the front edges


27


of the side walls


24


and


25


and defines a cutaway arcuate front opening


29


in the top wall


26


, as can best be seen in

FIGS. 1 and 3

. The peripheral wall structure


23


also includes a generally rectangular bottom wall


30


having a flat rear portion


31


and a slightly downwardly and forwardly sloping front portion


32


terminating in a beveled lip


33


.




Referring also to

FIGS. 5 and 7

, respectively integral with the side walls


24


and


25


and projecting laterally inwardly therefrom are elongated webs


34


, which are substantially parallel to the bottom wall


30


and are integral at their inner ends with rails


35


which are generally oval in transverse cross section, the oval having a major axis substantially perpendicular to the bottom wall


31


. The lateral inner surfaces of the rail


35


are cut away to define recesses


36


spaced apart by stiffening webs


37


. Projecting laterally inwardly from the forward end of each rail of


35


is a short stop lug


38


. Integral with each sidewall


24


,


25


a short distance rearwardly of the rear end of the associate rail


35


is a mounting post


39


with narrow rectangular bosses


39




a


immediately thereabove and therebelow (one shown in FIG.


7


). Respectively integral with the side walls


24


and


25


and projecting laterally inwardly therefrom, just rearwardly of the mounting posts


39


, are retaining projections


40


, each including a narrow rectangular rib


41


integral with a downwardly-opening, general C-shaped flange


42


(see FIGS.


7


and


8


).




Respectively mounted on the mounting posts


39


are two substantially rectangular stop plates


44


, each having a circular central opening therethrough receiving the associated post


39


, being retained in place by a toothed washer


46


, such as a Tinnerman washer, which fits over the associated mounting lug


39


to firmly mount the stop plate


44


in place. The bosses


39




a


provide parallel seating surfaces for the stop plates


44


on the diverging side walls


24


,


25


. Each stop plate


44


has a laterally inwardly projecting flange


45


at a forward end thereof which is disposed in use against the rear or inner end of the associated rail


35


.




Referring also to

FIG. 4

, the dustpan


20


has a handle assembly


50


including an elongated shaft


51


provided at the distal end thereof with an overmolded grip


52


, which may be formed of a suitable elastomeric material, such as that sold under the trademark SANTOPRENE. The grip


52


is provided at its lower end with a forwardly projecting C-clip


53


. The proximal end of the shaft


51


is socketed in the neck portion of a generally y-shaped yoke


55


having a pair of legs


56


, respectively defining concave recesses


57


on the sides thereof generally facing downwardly and forwardly in use. Each leg


56


is provided at its proximal end with a retaining extension


58


provided at its end with a thickened stiffening lug


59


.




Referring in particular to

FIGS. 5 and 6

, each retaining extension


58


has formed therethrough a generally keyhole-shaped aperture


60


, including a circular portion


61


and a generally triangular tongue portion


62


. The legs


56


are disposed in use just laterally inwardly of the rails


35


, being respectively connected thereto by couplers


65


. Each coupler


65


includes a generally cylindrical shank


66


which extends through the aperture


60


in the associated leg


56


, the shank


66


being provided at its inner end with a keyhole-shaped head


67


dimensioned to fit through the aperture


60


in the associated leg


56


in one orientation. Each coupler


65


is provided at the opposite end of the shank


66


with a generally C-shaped channel


68


adapted to slidably receive the associated rail


35


therein, as can best be seen in FIG.


5


.




In assembly, the heads


67


of the couplers


65


are respectively fitted through the keyhole-shaped apertures


60


in the legs


56


from the outside to the inside, and then rotated 180 degrees, so that the tongue portions


62


extends toward the distal ends of the legs (see FIG.


6


). Then, the channels


68


are slipped over the rear ends of the rails


35


and the stop plates


44


are then mounted in place, the stop plate flanges


45


cooperating with the stop lugs


38


on the rails


35


to prevent the couplers


65


from coming off the rails


35


. Thus, the couplers


65


cooperate to form a coupling mechanism which permits sliding movement of the handle


50


along the rails


35


between a forward position against the stop lugs


38


(see

FIG. 5

) and a rearward position against the stop flanges


45


(see FIGS.


3


and


8


), while at the same time accommodating pivotal movement of the handle


50


about the axes of the coupler shanks


66


relative to the receptacle


21


. When the handle


50


is in its rearward position and in a storage condition generally parallel to the bottom wall


30


, the retaining extensions


58


of the handle legs


56


will respectively overlie the retaining projection ribs


41


, as can best be seen in

FIG. 8

, for a purpose to be explained more fully below.




When the handle


50


is slid to its forward position it can be pivoted between the storage condition and an upright use position (see FIG.


5


), wherein the longitudinal axis of the shaft


51


is disposed at a large acute angle to the bottom wall


30


. More specifically, as the handle


50


is pivoted upwardly, the distal ends of the retaining extensions


58


frictionally engage the inner surface of the bottom wall


30


, just rearwardly of the sloping front portion


32


thereof and, as pivoting movement of the handle


50


continues, the bottom wall


30


flexes slightly to allow the distal ends of the retaining extensions


58


to cam forwardly past the junction between the rear portion


31


and sloping front portion


32


of the bottom wall


30


until the handle legs


56


engage the front edge


28


of the top wall


26


in a use position, wherein the longitudinal axis of the shaft


51


is tilted just slightly rearwardly past the vertical (see FIG.


5


). Thus, the retaining extensions


58


undergo a camming, over-center movement to resiliently retain the handle


50


in its upright use condition. It will be appreciated that the arcuate front opening


29


in the top wall


26


accommodates the pivotal movement of the handle


50


.




Referring also to

FIG. 9

, the broom


70


includes a handle


71


having an elongated hollow tubular shaft


72


provided at its distal end with an overmolded grip


73


, which may be formed of SANTOPRENE and may have a hole


74


formed therethrough at the distal end thereof. The broom


70


also includes a head


75


having a generally flattened, hollow housing


74


provided with a cylindrical neck


76


and flattened, generally triangularly-shaped front and rear walls


77


and


78


, joined by arcuate, sloping sides


79


. The broom


70


includes a plastic bristle plate


80


having holes or apertures formed in the lower surface thereof for respectively receiving bunches of bristles


82


, which may be secured in place by adhesive or other suitable means. The bristle plate


80


has a neck post


83


projecting upwardly therefrom centrally thereof and is received in the lower end of the hollow handle shaft


72


, being secured in place by any suitable means. The bristle plate


80


has a snap rim


85


formed on the outer periphery thereof adapted for engagement with snap beads


84


projecting laterally inwardly from the head housing


74


adjacent to its lower end (see FIG.


3


).




In assembly, the lower end of the handle shaft


72


is fitted through the upper end of the head housing neck


76


and is secured to the neck post


83


of the bristle plate


80


. Then, the handle shaft


72


is pulled upwardly, drawing the bristle plate


80


upwardly into the lower end of the head housing


74


until the snap rim


85


snaps past the snap beads


84


, for locking the bristle plate


80


in place, with the bristles


82


projecting downwardly well below the lower end of the head housing


74


. The handle shaft


72


is preferably circular in transverse cross section and is dimensioned to be snap-fitted in the C-clip


53


of the dustpan-handle


50


(see

FIG. 2

) for attaching the two together. Also, as can best be seen in

FIGS. 2 and 3

, the broom head


75


and, in particular, the sloping sides


79


thereof, are dimensioned and shaped to nest in the leg recesses


57


of the dustpan handle


50


in a stowed condition, with the broom handle shaft


72


retained in the C-clip


53


just below the grip


73


. When thus stowed, the broom


70


can move with the dustpan handle


50


and does not interfere with either its pivoting or sliding movements.




Thus, after the broom


70


has been attached to the dustpan handle


50


, preferably when the handle


50


is in its upright use position, the dustpan handle


50


can be pivoted downwardly to its storage position. Then, when the dustpan handle is held upright, the dustpan receptacle


21


will, by gravity, hang freely with the couplers


65


in their forwardmost positions against the stop lugs


38


. The receptacle


21


may then be supported on its rear end wall


22


and the handle


50


and attached broom


70


may be dropped into the receptacle


21


, with the retaining extensions


58


respectively riding over the retaining projections


40


(see

FIGS. 2

,


3


and


8


). Thus, the engagement of the retaining extensions


58


with the retaining projections


40


prevents pivotal movement of the handle


50


toward the top wall


26


, while engagement of the broom head housing


74


with the receptacle bottom wall


30


prevents pivotal movement in the opposite direction, so that the combination


10


will remain balanced on the receptacle rear end wall


22


and not tip over.




When it is desired to use the combination


10


, the joined handles are simply grasped and pulled upwardly, allowing the receptacle


21


to drop away until the couplers


65


stop against the stop lugs


38


at the forward ends of the rails


35


, as shown in FIG.


10


. Then, the receptacle may be laid down with its bottom wall


30


on the floor


15


and the handle


50


pivoted to its use position, as explained above (see FIG.


11


), whereupon the broom


70


can be disengaged from the handle


50


for use, as shown in FIG.


12


.




Preferably, the combination


10


is formed of suitable plastic materials, except for the Tinnerman washers


46


and the handle grips


52


and


73


. The broom bristles


82


may also be formed of suitable plastic materials. Preferably, the receptacle


21


, the handle yoke


55


and the broom head


75


are of molded, one-piece construction, as is the bristle plate


80


. However, it will be appreciated that, if desired, other materials and fabrication techniques could be used.




From the foregoing, it can be seen that there has been provided an improved dustpan and broom combination, wherein the dustpan handle can be easily moved between storage and use positions with one hand, by undergoing a combined pivoting and sliding movement, and the broom can be stowed on the dustpan handle without interfering with its pivoting and sliding movements.
