SWING-WING DUST MOP BACKGROUND OF THE INVENTION This invention relates to improvements in cleaning implements. More particularly, this invention relates to improvements in mops and the like.

When mopping a floor, it is often desirable and necessary to increase the area of floor engaged by the mop to reduce the amount of time needed to complete a task. The problem of increasing the area of a floor engaged by a cleaning surface, such as the fabric head of a dust mop, has of course been recognized and has been dealt with by those involved in cleaning large floor areas. such as those of industrial plants or the like. The prior art includes several patents which disclose mops and brooms having pivoted sections which fold away from one another to increase the area of floor engaged by the mop or broom. US. Pat. Nos. 2,756,453, 1,784,567, 2,614,281 and 2,860,360 exemplify this type of device. However, as seen in the aforementioned disclosures, this type of cleaning device is generally rather heavy-duty, large and expensive, and generally not suitable for home use.

In addition to being able to increase the area of floor engaged by a cleaning implement such as a mop, it is also desirable in utilizing the same cleaning implement to be able to decrease the floor area engaged in order to get under and around furniture. This again has not been adequately dealt with by prior art devices. In the past, the ordinary house mop had to be turned sideways in order to accomplish this. When the mop is turned sideways, the handle, which is generally pivoted thereto, cannot pivot down so that the mop can be easily pushed under a low-lying object, such as a shelf or the supporting structure of a chair or the like. This deficiency in the ordinary house mop causes considerable inconvenience and irritation.

Furthermore, the above-cited devices do not utilize the technology which is currently being applied in the home consumer market. For example, the aforementioned devices do not utilize resilient, light plastic supporting structures which can be readily assembled. Consequently, the afore-described devices cannot be broken down into easily assembled component parts for storage and shipment. It is well known that great economy results from being able to store and ship unassembled articles, and the cleaning implements of the prior art do not teach how to apply this economy to dust mops purchased by consumers for home use.

SUMMARY OF THE INVENTION In view of the afore-described problems, it is an object of the instant invention to provide a new and improved cleaning implement.

It is another object of the instant invention to provide a new and improved cleaning implement which is foldable so as to either reduce or increase the area engaged by the cleaning implement.

It is still another object of the instant invention to provide a cleaning implement which can be made from lightweight plastic materials.

It is a further object of the instant invention to provide a cleaning implement, such as a mop, which can be broken down into easily assembled component parts for storage and shipment.

In accordance with these and other objects. the instant invention includes a mop head, which may be disposable, having an elongated array of fabric-type material which is attached to a mounting vane that is, in turn, mechanically secured to a pair of pivotable arms. The arms are mounted in a bracket member and are positively coupled so as to move in opposite directions when only one of the arms is pivoted. The bracket member has a socket pivoted thereto which receives a handle.

Other objects and advantages of the present invention will become apparent from the following description of a preferred embodiment of the invention, taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE DRAWINGS Referring now to FIG. 1, there is shown a mop, according to the invention. which includes a mop head 20 having an array of fabric strands 21-21 which are used to collect dust. It is to be understood that the array of fabric strands 21 may also be any type of dirt-removing or dirt-transporting fabric or device. The mop head 20 is secured to a pair of

arms

22 and 23 which project from a connecting bracket, designated generally by the numeral 24. The connecting bracket 24 has a pair of

flanges

26 and 27 extending upwardly from a top panel 25 to which a socket, designated generally by the numeral 28, is pivoted. The socket 28 threadably receives a wooden or plastic handle 29.

Referring now to FIG. 2, it is seen that the fabric strands 21 are secured to a binding strip or vane 31 by stitching (not shown) or some other conventional securing method. The vane 31 is preferably of a flexible material, such as vinyl or the like, and has a circular bead 32 extending along the top edge thereof. The circular bead 32 has a diameter greater than the width of the vane portion 31 to which the strands are attached, and is received in a slot 33 which projects from a bottom panel 34 of the connecting bracket 24. The slot 33 is defined by a pair of converging ribs 35-35 which have a space therebetween which is large enough for the vane 31 to pass therethrough, but which is narrower than the bead 32. An enlarged view of the slot 33 is seen in FIG. 16.

As best seen in FIGS. 2 and 3, the socket 28 has a forked end 36 which is inserted between the

flanges

26 and 27, and is pivoted on a pair of

projections

37 and 38 which extend from the flanges into

apertures

39 and 41 formed in the forked end of the socket. FIG. 2 shows the socket 28 and handle 29 projecting from the bracket 24 in what might be called a normal cleaning attitude. However, it is to be understood that the socket 28 can pivot about the

projections

37 and 38, either clockwise or counter-clockwise from the position shown in FIG. 2 to lay either along the bracket 24 or away from the bracket 24. When the socket 28 is thus pivoted, the mop head and the handle 29 will extend in generally the same plane so that the mop may be stored easily in a closet or the like. In addition, when the handle 29 is pivoted down in the clockwise direction, the mop may be easily slid under low-lying furniture.

In order to retain the socket 28 and the handle 29 in either of the afore-mentioned positions, and in order to prevent the mop head from assuming an inconvenient angle relative to the handle 29 while a floor is being mopped, a rib 43 projects up from the top panel of the bracket 24 to engage a pair of

detents

44 and 45 projecting from the forked end 36 of the socket 28. As the

detents

44 and 45 ride over the rib 43, they cam the two prongs of the forked end 36 together so as to decrease the distance separating the ends of the detents. This allows the

detents

44 and 45 to slide over the rib 43 and provides a way of holding the handle 29 in either an overlying or extended position relative to the mop head 20 so that greater flexibility for using the mop results, for example, for use under low-lying objects and around furniture legs.

As best seen in FIG. 3, the

arm members

22 and 23 are pivoted about

bearings

51 and 52 which project from the bottom panel 34 of the bracket 24. The

arms

22 and 23 may assume either the extended configuration indicated by the dotted lines in FIG. 3, or the narrow configuration shown by solid lines in FIG. 3. In order to coordinate the pivotal motion of the

arm members

22 and 23 so that as one of the arms pivots, the other arm will pivot in the opp'osite direction, each of the arms has an integral gear segment 53 which meshes with a gear segment on the other arm to positively couple the arms together. It is to be understood that such coordinated motion of

arm members

22 and 23 could also be accomplished by rotating an indicator dial (not shown in the figures) which, alternatively, meshes with the gear segment of only one of the meshed arm members, or meshes with intermediate members having gear segments that in turn mesh with the gear segments of the arm members.

It has been found that it is desirable for the

arm members

22 and 23 to have a mid-position between the extended dotted line configuration and the narrow solid line configuration. This is accomplished by detents 56-56 which project from each of the

arm members

22 and 23 to engage apertures 57 formed in the bottom panel 34 of the bracket member 24 (see FIG. 11). As the

arm members

22 and 23 rotate between the dotted line and solid line positions, the projections 56 are received in the apertures 57 to retain the arm members and thus the mop head 20 in the desired configuration.

In order to distribute the fabric strands 21 so that the mop can easily clean along walls and the like without having to turn the mop sideways, each of the

arms

22 and 23 have

angular bends

59 and 60 therein which extend rearwardly from the arms.

An important consideration in the instant invention is that the instant invention provides a cleaning implement which can be readily assembled. This is due, in part, to the construction of the bracket 24. As best seen in FIG. 11, the bracket 24 is formed of a single piece of material which is hinged along a thin seam 58 which joins the bottom panel 34' of the bracket to the top panel 25. When the bracket 24 is folded about the hinge 58, the top panel 25 overlies the bottom panel 34 aligning a pair of detent members, designated generally by the numeral 61-61, with apertures 62-62 that 1 project through the

bearings

51 and 52. Upon pressing the top panel 25 and bottom panel 34 together, the detents 61-61 slide into the apertures 6262.

As best seen in FIGS. 2 and 17, the detents 61-61 are bifurcated and have shoulders 63-63 thereon' which fit beneath annular shoulders 64-64 projecting into the apertures 62-62 of the

bearings

51 and 52. This securely fastens the top panel 25 to the bottom panel 34, forming the bracket 24 into a housing for supporting the

arms

22 and 23.

Generally, the mop is put together by placing the

arms

22 and 23 over their

respective bearings

51 and 52 with the

gear sectors

53 and 54 in meshed engagement and the detents 56-56 engaging the same relative positioning slots 57-57. The top panel 25 of the bracket 24 is then folded at the hinge 58 until the detents 61-61 are aligned with the apertures 62-62 on bottom panel 34. The

panels

25 and 34 are then squeezed together to snap the shoulders 63-63 beneath the annular shoulders 64-64 to hold the panels together and the arms 22and 23 in place. Preferably, the resulting unit is then ultrasonically vibrated to promote the melting of projections (see FIG. 11) and the formation of a weld at these locations between

panels

25 and 34, which ensures the secure engagement of meshed

arms

22 and 23.

The threaded handle socket 28 is then mounted between the

flanges

26 and 27 by squeezing the forked end 36 of the threaded socket together so that the socket will slide between the

pivots

37 and 38. In order to facilitate sliding the socket into place, the pivots37 and 38 become aligned with the

apertures

39 and 41 in the forked end 36 of the threaded socket 28, the prongs of the forked end will spring outwardly to retain the threaded socket pivotally between the

flanges

26 and 27.

The mop head 29 is attached to the

arms

22 and 23 by sliding the bead 32 of the vane 31 into

slots

68 and 69 extending between converging ribs 71-71 and 72-72 projecting from each of the arm members. The vane 31 is slid through the slots 7l-71 and 7272 until short portions thereof project from the end of each of the

arms

22 and 23. These short portions are then doubled back and pressed into slots. 7373 formed by deflectable ribs 74-74, which converge toward the inner ribs 72-72. The ends of the vane 31 are consequently secured to the

arms

22 and 23 so that the vane and the associated mop head cannot be slid out of engagement with the arm members.

It is preferable that the

arm members

22 and 23,the bracket 24and the threaded socket 28 all be made of a resilient, self-lubricating, plastic material to facilitate easy assembly and operation of the afore-described cleaning implement.
