DESCRIPTION OF THE PREFERRED EMBODIMENT As shown in the drawings, a work-head and handle assembly embodying the present invention is formed with a work-head 20 having an elongated handle rod 21, generally circular in cross section, extending upwardly at an angle convenient for the user. The relative angle or position between the work-head 20 and the handle 21 may be adjusted to suit the users convenience depending upon the particular task for which the tool is being employed. While cleaning tools and like implements are generally known, the present invention is embodied in certain new, useful and unobvious improvements in such implements which increase and enhance the utility of these tools.

The work-head 20 is formed by a generally flat or relatively thin body member or block 22 carrying an adjunct main tool or implement, such as a sponge 24, and an auxiliary tool or implement 25 selected from various types of accessory tools such as brushes of varying stiffness, abrasive plastic pads, scrapers, Squeegees, spreaders and the like. In the form shown in the drawings, the work-head includes a readily detachable sponge mop type tool 24 associated with a selected accessory implement such as a brush as shown in FIG. 1. It will be appreciated that the sponge 24 may be of a selected consistency and further may additionally include scrubbing features or elements such as stiff fibers, steel or abrasive plastic padding, or the like. To further increase and enhance the utility of the work-head, means are provided which cooperate with the accessory and sponge mop elements to adapt the unit for still further function such as waxing and polishing. To this end, the structure contemplates the attachment of an auxiliary slip-on cover 26 as shown in the drawings.

The cleaning tool or implement shown and described herein is adaptable for cleaning not only floors, but also walls, ceilings and other surfaces. Accordingly, it is desirable to be able to position the angle of the body or work-head 20 with respect to the handle rod 21 in order that sponges, implements and the like carried on the body are directed in the most convenient position or angle for the particular task to be performed. To this end, an improved handle positioning assembly, indicated generally at 28, is provided as a part of the invention.

The new and improved mop base or head 20 embodying the present invention has, as its supporting base member, a generally rectangular flat base member or block 22 having upper and lower plane surfaces 30, 31, respectively, and further defining front and rear longitudinal side surfaces or planes 32, 33, respectively, and opposed side or end surfaces or planes 34, 35, respectively. The adjustable handle mounting assembly 28 is secured to the base member 22 adjacent the rear longitudinal side plane 33, thereby leaving the upper and lower surfaces or faces 30, 31 of the block substantially unobstructed. With this construction, the mop base or head 20 may be readily squeezed in a utility container wringer such as the apparatus shown in US. Pat. No. 3,614,802 or my copending application referred to above.

In the mop base member or block 22 as shown, the upper and lower faces 30, 31 thereof are defined by spaced plates 36, 37, which for convenience in description will be referred to as being generally horizontal, joined together in spaced relation by one or more spaced, narrow, longitudinally extending vertical webs, two such webs 38, 39 being show in the drawings. Further in the embodiment shown, one of the vertical webs 38 is positioned as an intermediate web approximately centrally between the upper and lower plates 36, 37, while a second web 39 is spaced from the central web and forms the rear longitudinal side edge surface of the block 22. The front portion of the block is open for purposes which will be described below.

At the open front plane of the block 22, the plates 36, 37 are formed with inturned edges or flanges 40, 41. For defining a channel with these flanges, the plates are further provided with ribs 42, 43 defined on the inner faces of the plates 36, 37 substantially equidistant between the flanges 40, 41 and the intermediate web 38. The inturned edge flanges 40, 41 and intermediate ribs 42, 43 define in association with each other a forward channel 44 for receiving a selected auxiliary implement 25 such as the body block of a brush, squeegee or the like.

For mounting within the body channel 44, the auxiliary implement 25 comprises a mounting block 46 (FIG. 8) which is shaped with a cross section substantially identical to the dimensions of the channel 44 and is of a length substantially equal to the length of the mop head body block 22. The auxiliary implement includes a brush 47 or similar device such as a squeegee 47 (FIG. 12) or other tool element. When the auxiliary implement 25 is mounted in the channel 44 the brush extends outwardly between the inturned edge flanges 40, 41 into working position as shown in FIG. 1.

In order to enclose the brush or working element when the auxiliary element is not in use, it may be reversed with the brush or other device extending inwardly into a second or inner channel 45 defined between the inner or intermediate ribs 42, 43 and the web 38 as shown in FIG. 5. With this construction, the brush is housed in a protected position. With the auxiliary brush turned inwardly, for example, the tool may be used in corners, the upper edges of walls against ceilings and in other places where it is desirable not to bump or mar an adjacent surface.

In order to receive and hold the auxiliary implement 25, the plates 36, 37 at least at their forward edges adjacent the flanges 40, 41 may be slightly resilient in order to provide a snug but tightly sliding fit with the implement block 46. The implement block 46 may be formed of wood, metal, plastic or other materials as desired, in accordance with the particular type of implement to be utilized. A variety of such implements may be provided with each mop head to enable the user to select the particular auxiliary tool to be employed for a given application.

The principal head or tool 24 of the mop as shown in the drawings is illustrated in the form of a sponge although it will be readily appreciated that other forms of work head elements may be utilized. In the form shown in the drawings, the sponge 24 is secured to the lower face 31 of the body block in a manner which securely holds the sponge in place and yet enables the user to readily replace itand insert another element if desired. To this end, the sponge 24 is provided with an attaching plate 50 (FIGS. 6 and 7) which is securely fastened to the upper surface of the sponge 24. The plate 50 includes a plurality of outwardly extending projections or tangs 51 which are adapted to be received in channels 52 defined on the lower face of the body block 22. The edges of the plate 50 from which the tangs project may desirably be turned downwardly to provide depending ribs 53 which bite into the upper surface of the sponge as shown in FIG. 7 when the plate 50 is mounted thereon. These ribs 53 hold the sponge against slipping or twisting with respect to the plate 50 and thereby increase the strength of the bond between the plate and the sponge.

For receiving the tangs 51 receiving channels 55 are defined by generally L-shaped members 54, 54 integrally formed on or otherwise secured to the lower plate 37. The tangs 51 are located on each longitudinal edge of the mounting plate 50 and are adapted to slide into and out of thechannels 55, to securely hold the sponge work head 24 in place on the body block 22.

Various types of sponges or other tool heads 24 may be utilized. For example, a scrubbing sponge may be employed which includes an abrasive pad on its work surface, or which includes fibers secured, bonded or otherwise imbedded in the work face of the sponge. It will also be observed that the sponge face is generally parallel to the upper face of the body block 22 so that the work head assembly can be squeezed between the plates of a utility wringer in order to remove waste liquids or other liquids from the sponge body. The front and rear edge surfaces desirably slope outwardly so that the sponge is generally trapezoidal in cross section, with the large face being the working face. In this manner the user can easily work into edges and comers. v

It has been further observed that by making the sponge work-head 24 generally trapezoidal in cross section, with the narrower surface secured to the mounting block 22 and the wider surface serving as the work surface, liquids tend to be retained, to prevent dripping, and the spreading action is substantially enhanced. For example, when washing a Wall, the upper sloping surface serves to catch liquid and prevents it from dripping down the wall when the mop is moved in an upwardly direction, while the lower sloping surface tends to spread liquid along the wall and prevent it from dripping.

To further enhance the utility of the sponge mop assembly and provide, for example, for its use as a polishing tool, means are provided for securing a slip-on wrapper or cover 26 over the sponge work head 24. For some applications, it is desirable to utilize a natural or synthetic wool, tufted or looped fabric such as for polishing, application of liquid waxes or other surface treating agents. The cover may be a washable or throwaway item, and is essentially supported and shaped by the underlying sponge tool head 24. One illustrative slip-on cover 26 is shown in FIG. 9 and includes a length of fabric such as a stretch or elastic fabric member or base 58 having opposed loop hems 59 adapted to receive stiffening rods 61 61 therethrough. One rod is provided with a plurality of hooks 62 adapted to be engaged over the inturned flange 41 on the forward edge of the block 22, the lower plate 37 is provided on its bottom surface 31 with a .l-shaped channel 64 integral with or closely adjacent the rear sponge-securing L-shaped channel member 55. To engage with the J- shaped channel 64 on the plate 37, one of the rods 61 on the slip-on cover is essentially a double length rod one length 65 of which is stitched into the hems 59 of the fabric slip-on cover 26. The other leg 66 engages in the .l-shaped channel 64 on the block plate 37. Also stitched, bonded or otherwise affixed to the slip-on cover is a body of the desired material 68 such as lambs wool or other natural wool, a synthetic wool, foamed or tufted plastic or the like.

In order to accommodate the books 62 on the slip-on cover as they are engaged over the lower plate flange 37, the block 46 of the auxiliary implement 25 is desirably notched at appropriate spots on both its front and rear surfaces as shown in FIG. 8 to provide recesses 69 within which the hooks 62 may be received. These notches or cutouts 69 correspond in number to the cover hooks 62 and receive these hooks when the slipon cover is positioned in place. The sponge head 24 provides a resilient backing and support for the particular fabric or material 68.

For scrubbing, waxing, polishing or buffing floors, the handle 21 is preferably positioned at an acute angle with respect to the face of the work head 24. In other words, the included angle between the handle 21 and the upper face 30 of the body block is an obtuse angle. The particular handle and work head position may, however, be inconvenient for other applications, such as washing walls, floors, ceilings, or in the event the user desires to work underneath a low object such as a table or bed. It is, therefore, desirable to be able to adjust the angle between the handle 211 and the work head 24 in order to position the work head according to the particular application. To this end, the invention embodies an improved positioning mechanism, one illustrative form of which is shown in the drawings.

Referring to the drawings, the handle 21 is adjustably secured to a handle bracket 70 as shown in FIG. 1 or directly to the body block or base member 22 as shown in FIG. 2. When a handle bracket 70 is utilized, it is in turn mounted along the body or base member 22 by means of fasteners 71 such as bolts, screws or the like.

For mounting the handle to the bracket 70 or body block 22 a pair of handle mounting arms 75 are provided which are pivotally mounted at one end to the bracket or body block and at their other end are either directly secured to the handle rod 211 by bolts 76 or may be provided with an internally threaded socket for receiving a like threaded end on the handle rod. The arms 75 are braced to the bracket or body block by laterally extending braces 78 which are also pivotally mounted to the bracket or body block at their lower ends, while th upper ends of the braces 78 are secured directly to the handle supporting arms 75 by the bolts 76.

For purposes of pivotally mounting the handle mechanism, the arms 75 and supporting brackets 78 are engaged by pins 79 which extend through flanges 72 which are integral with either the bracket web 74 or are fastened to the rear edge of the body block 22 by the angle brackets 80 as shown in FIG. 2. With the foregoing construction, the handle can be positioned at any desired angle with respect to the base member 22 and thereby with respect to the main tool 24 and auxiliary tool 25.

For adjustably fixing the handle position with respect to the base 22 to hold the handle at the desired angle, a spring biased bolt type locking mechanism 80 is provided. This locking mechanism or assembly 80 includes a pin, bolt or lock bar 81 engagable in a selected one of correspondingly shaped slots 82 in a slotted member 84 secured to either the handle mounting bracket 70 or directly to the base 22. The slotted member 84 is generally arcuate in shape and is provided with mounting means, for example upper and lower mounting flanges 85 as shown in FIG. 4, by means of which it is mounted on the bracket 70 or base 22.

For guiding the locking pin or bolt 81, spaced upper and lower guide plates 86, 87 are secured between the handle supporting arms 75. In the form shown, the guide plates each have opposed laterally extending tangs 88 which project through correspondingly formed slots 89 in the handle arms 75. The bolt 81 slides through central apertures 90 in these guide plates 86, 87 and is spring biased to its outwardly extending or engaging position by a coil spring 91. The coil spring 91 surrounds the bolt 81 and acts between the upper guide plate 86 and a stop pin 92 extending through the bolt 81. The spring 91 urges the bolt 81 into locked engagement with a selected slot 82 in the locking member or strike plate 84. into Means are provided for retracting or lifting the bolt 81 out of a given slot 82 against the force of the spring 91. For this purpose, a generally U-shaped member 94 surrounds the latch bolt 81 and extends upwardly generally parallel to the handle arms 75 to a point at which the free ends of its respective legs 95 are engaged with a sliding sleeve 96 positioned in surrounding relation with the mop handle rod 21.

By pulling upwardly on the sleeve 96 the U-shaped actuating member 94 pulls the latch bolt 81 against the force of the spring 91 and thereby disengages the bolt 81 from a slot 82 in the strike plate 84. The handle may then be swung to any desired position relative to the body block 22 and the latch bolt reengaged in the nearest hole to hold the handle in the new position. Alternatively, a trigger or like handle mounted assembly may be utilized to actuate the latch bolt 81.

It will be observed that a highly versatile cleaning implement has been provided in which each of the associated elements coacts to provide an enhanced utility for the implement. The coacting elements provide a highly versatile tool suitable for a wide variety of cleaning, liquid applications, and related operations. The

tool is of a construction which permits autoclaving for use in applications requiring sterile tools and conditions. The body block, sponge work head and auxiliary implements may be provided of any desired size, particularly length, so that the tool is adaptable not only for home use but also may be constructed in larger sizes for industrial and institutional use.

While certain illustrative embodiments and modifications have been shown in the drawings and described above in considerable detail, it should be understood that there is no intention to limit the invention to the specific forms disclosed. On the contrary, the intention is to cover all modifications, alternative constructions, equivalents and uses falling within the spirit and scope of the invention as expressed in the appended claims.
