SUMMARY OF THE INVENTION
The present invention is a cleaning implement such as a scrub brush attachment which removably holds the scrub brush attachment in place on a butterfly mop head and will not fall off during the vigorous scrubbing action because it is locked in place by means of a novel attaching mechanism. The present invention is comprised of a receiving channel molded into the mop head, the channel receiving the unique locking member of the present invention attachment mechanism. The attachment comprises an elongated base member which on one side permanently retains a scrub brush. On the opposite side, the base member comprises a transverse wall supporting the locking member which is an elongated snap wing extending in one direction so that when the snap wing is slid into the receiving channel, the snap wing is press fit into and retained within the receiving channel with the opposite lips of the snap wing abutting opposite elongated interior walls within the receiving channel to lock the base in place within the channel.
It has been discovered, according to the present invention, that for a butterfly mop having a molded head made of materials such as plastic, rubber, or polyurethane, an attachment mechanism comprising at least one snap wing which can be inserted into a channel molded into the butterfly mop head with the at least one snap wing having a opposite lips abutting both interior walls of the molded channel, will enable the mechanism to be securely retained on the mop head and can retain a scrubber pad or scrub brush during vigorous scrubbing action.
It has further been discovered, according to the present invention, that if the mechanism further contains at least one wall or stop member which abuts one end of the channel walls, lateral movement of the mechanism during vigorous scrubbing will be prevented.
It has further been discovered, according to the present invention, that the preferred shape and the receiving channel walls is “L” shaped, however other wall shapes are within the spirit and scope of the present invention.
It has additionally been discovered, according to the present invention, that while at least one snap wing is the preferred embodiment, any configuration having more than one snap wing with the adjacent snap wings extending in opposite directions to be received within the molded channel is within the spirit and scope of the present invention.
It is therefore an object of the present invention to have an attachment mechanism to removably and securely retain a scrubber pad and/or scrub brush attachment on a butterfly mop.
It is a further object of the present invention to provide a mechanism to lock the scrubber pad or scrub brush retained into a receiving channel affixed to a mop head so that the mechanism will not move and will not fall out of the channel during a vigorous scrubbing process.
Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
The innovation of the present invention is a scrub brush attachment which removably holds the scrub brush in place on a molded butterfly mop head and will not fall off during the vigorous scrubbing action because it is locked in place by means of a novel attaching mechanism. The innovation of the present invention is also a scrubber pad attachment which holds the scrubber pad in place on a molded butterfly mop head and will not fall off during the vigorous brushing action because it is locked in place by means of a novel attaching mechanism. The present invention is comprised of a receiving channel molded into and thereby affixed to the molded mop head, the channel receiving the unique locking member of the present invention attachment mechanism. The attachment mechanism comprises an elongated base member which on one side either permanently or removably retains a scrubber pad or permanently retains a scrub brush. On the opposite side, the base comprises a transverse wall which supports the locking member which is at least one snap wing which is snapped into or slid into and retained by a press fit within the receiving channel with the at least one snap wing abutting opposite elongated interior walls within the receiving channel to lock the base in place within the channel.
The base further comprises at least one transversely extending stop member which is located at one end of the at least one snap wing and positioned such that when the at least one snap wing is locked within the channel, the transverse side member is positioned immediately outside one end of the receiving channel so the base cannot move laterally. As a result, the base is firmly locked within the receiving channel and won't move during vigorous scrubbing action.
Referring to FIGS. 1, 2 and 4, there is illustrated at 100 a butterfly sponge mop which has a shaft 110 onto which is positioned a slidable handle 120 connected to a connecting rod 130 which in turn is connected to a butterfly mechanism 140 which is positioned above a molded plate 150 having a left section 152 and a right section 154. The butterfly mechanism 140 has two butterfly operating members 142 and 144 which when activated respectively rotate left section 152 and right section 154 of the molded plate 150. A molded housing 160 is fixed to a location preferably adjacent the bottom of shaft 110 and preferably on the top surface 168 of the molded housing and rests above the top 156 of molded plate 150 and also is positioned between left section 152 and right section 154 of molded plate 150. The fixed molded housing 160 rotatably supports the butterfly mechanism 140 and its operating members 142 and 144 and also rotatably supports the left and right plate sections 152 and 154. A cleaning sponge 170 is attached to the bottom 158 of molded plate 150 by attaching means such as mating hook and loop fasteners 162 and 164, with one fastener 162 attached to the bottom 158 of molded plate 150 and the other fastener 164 attached to the sponge 170. When slidable handle 120 is moved downwardly on shaft 110, the butterfly mechanism 140 which is rotatably supported by the fixed molded housing 160 and the molded plate sections 152 and 154 which are also rotatably supported by the fixed molded housing 160 causes both sections 152 and 154 to rotate downwardly away from fixed molded housing 160 so that side sections 172 and 174 of the cleaning sponge 170 are squeezed together to drain water and dirt from the cleaning sponge 170. When the slidable handle 120 is returned to its normal position, the molded plate sections 152 and 154 and sponge 170 and its sections 172 and 174 rotate back to their normal position. This paragraph describes the normal operation of a conventional butterfly sponge mop 100 having a molded housing 160 including rotatable molded plate 150 and its sections 152 and 154 which supports the sponge 170 and a fixed molded housing 160 attached to the shaft 110 of the butterfly mop 100.
Because the fixed head 160 is molded, it is possible to incorporate a molded receiving channel into the head, preferably on the front surface 166. The present invention attachment mechanism 10 addresses the problem found in conventional scrub brush attachment mechanisms which come loose from the head 160 because of vigorous scrubbing action required to loosen the ingrained soil areas. Referring to FIG. 9, the present invention attachment mechanism 10 comprises a receiving member 20 which has a first “L” shaped wall 22 which includes a first sidewall 24 attached to or molded into the head 160 at one end and terminating in a first transverse wall 26 at its other end.
The receiving member 20 further comprises a second “L” shaped wall 32 which includes a second sidewall 34 attached to or molded into the head 160 at one end and terminating in a second transverse wall 36 at its other end. The first “L” shaped wall 22 and the second “L” shaped wall 32 are mirror images of each other so that they are spaced apart with first sidewall 24 aligned parallel to second sidewall 34 and first transverse wall 26 extending toward second transverse wall 36 and second transverse wall 36 extending toward first transverse wall 26 so that a channel 40 is formed between first sidewall 24 and second sidewall 34 and an elongated gap 42 is formed between first transverse wall 26 and second transverse wall 36 which leads into channel 40.
First sidewall 24 terminates in a first transverse end 21 and an opposite second transverse end 25 and first transverse wall 26 terminates in a first transverse end 23 and an opposite second transverse end 27. Similarly, second sidewall 34 terminates in a first transverse end 31 and an opposite second transverse end 35 and second transverse wall 36 terminates in a first transverse end 33 and an opposite second transverse end 37. The transverse ends 21, 23, 31 and 33 are all aligned and transverse ends 25, 27, 35 and 37 are all aligned.
The second component of the present invention attachment mechanism is an elongated base 50 having a front side 52 to which a multiplicity of bristles 54 are attached. The scrubber brush bristles 54 are permanently attached to the front side 52 of elongated base 50. When affixed to the base 50 in this manner, the bristles 54 of scrub brush 56 face outwardly as illustrated in FIGS. 3 and 4 so that the bristles 54 can be rubbed against the wall or floor being washed.
The rear side 60 of elongated base 50 contains the at least one locking member snap wing 62 as best illustrated in FIGS. 2, 6, 7 and 10. A transverse wall 64 extends from the rear side 60 of base 50 and runs almost the entire length of base 50. Positioned at the center of transverse wall 64 is snap wing 62 which extends for approximately one-third (1⁄3) of the length L1 of transverse wall 64. From the view illustrated in FIGS. 2 and 7, there is a stop block 66 positioned to one side of snap wing 62. The transverse wall 64 is solid from the side 63 opposite the stop block 66 and extending to end 68. An upper elongated groove 70 is formed into wall 64 and is positioned adjacent to top 72 of wall 64 and extends from opposite end 74 through snap wing 62 and terminates at stop block 66. The groove 70 creates an upper lip 76 on one side of the snap wing 62, the upper lip 76 located adjacent the top 72 of transverse wall 64. As illustrated in FIGS. 6 and 10, on the opposite side 65 of transverse wall 64 there is a larger groove 78 which is positioned adjacent to the bottom 80 of the transverse wall adjacent to base 50 and extends from end 74 through the wall of the snap wing 62 and up to the location of the stop block 66 to create a large lower lip 82 on snap wing 62. As illustrated in FIG. 10, the large lower lip 82 is at the approximate mid height of the transverse wall 64.
As illustrated in FIG. 11, the base 50 is positioned so that the snap wing 62 is aligned with the channel 40 and is slid into channel 40 to form a press fit so that first transverse wall 26 slides into upper elongated groove 70 and upper lip 76 is pressed into the corner between first sidewall 24 and first transverse wall 26. On the opposite side, transverse wall 36 is slides into lower elongated groove 78 and lower lip is 82 is pressed against the interior of second sidewall 34 at a location below second transverse wall 36. The snap wing is press fit slid in this manner until the stop block abuts the end 37 of second transverse wall 36 and the intersection of the end 25 of first sidewall 24 and end 27 of first transverse wall 26 to cause the sliding to stop. In this manner, the snap wing 62 is firmly press fit into channel 40 and retained therein with further lateral movement being prevented by stop block 66. As a result, because of the strong press fit, the butterfly mop 100 can engage in a vigorous scrubbing action with scrub brush 56 so that the scrub brush 56 will not come loose during vigorous scrubbing.
It will be appreciated that numerous alternate configurations are within the spirit and scope of the present invention to have a multiplicity of snap wings to retain the elongated base 50 within the receiving member 20. The present invention will work with any two snap wings with upper and lower lips pointing in opposite directions to be respectively received by transverse walls 22 and 32 of receiving member 20 so that the snap wings are press fit within channel 40 with further lateral movement being prevented by stop block 66.
In the preferred embodiment, the first and second “L” shaped walls 22 and 32 are molded to the front surface of the molded housing.
The molded housing 160, the first and second sidewall 24 and 34, and first and second transverse wall 26 and 36 of the receiving member 20, and the base 50, the transverse wall of the base 64, the upper and lower groove 70 and 78, the upper and lower lip 76 and 82, and the stop block 66 are all formed from material selected form the group comprising plastic, rubber and polyurethane.
