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 new innovation has a single trigger mechanism to release the disposable microfiber cloth or non-woven cloth from a flat mop. This is also applicable to a microfiber mop. It has a single trigger release mechanism. The mop may have a yoke which rotatably retains a handle above a housing which retains the retained the trigger mechanism, or the mop can have a handle retaining mechanism without a yoke.
Essentially there are three major components that have been described. The first component is a top plate. The second component s is a mechanical plate. The third component is a push plate.
With respect to the top plate, the top plate is strictly stationary. It has a flat top surface with a yoke which rotatably restrains a handle so a user can push the microfiber flat mop in a back-and-forth direction with the handle that goes into the collar in the yoke. The top housing encloses a trigger mechanism.
The device consists of three components as follows:
1. A top plate
2. A mechanical plate
3. A push plate
The mechanical plate is sandwiched between the top plate and the push plate which retains the cloth in one of two alternative embodiments so that the cloth can be removed after it is dirty and disposed of without a hand having to touch the cloth.
Referring to FIG. 1 there is illustrated a rear top plan view of the top plate 10 illustrating the yoke 1000 in the opened condition and affixed to the housing 100 which retains the trigger mechanism, with the trigger 110 illustrated. The yoke 1000 has a first post 1010 with a U-shaped retaining section 1020 and a second parallel spaced apart post 1030 with a U-shaped retaining section 1040. The U-shaped retaining sections 1020 and 1040 are parallel. Referring to FIG. 2 there is illustrated a front top perspective view of the top plate. The top plate is numbered 10 and has a top surface 20. A handle 1100 is rotatably retained by the U-shaped retaining sections 1020 and 1040 in posts 1010 and 1030 of yoke 1000. The mechanism enables the mop top plate 10 to rotate back and forth as the handle is pushing the mop to scrub a surface, primarily a floor.
Further referring to FIG. 1, beneath the yoke 1000 is the present invention trigger mechanism housing 100 illustrating the trigger 110. The top plate also includes a first cover member 300 and a second cover member 310.
Referring to FIG. 3, there is illustrated a bottom perspective view of the top plate 10. The bottom 20A of the top plate 10 has male mating members 32, 34, 36 and 38 adjacent a first side 31 and male mating member 42, 44, 46 and 48 adjacent an opposite second side 35 which will mate with female receiving members on the mechanical plate to be discussed subsequently. The bottom 20A of the top plate 10 also has molded into the bottom surface 20A a pair of spaced apart steel pins 50 and 60 which are molded into the bottom surface 20A and serve as up and down guides after assembling the mechanical plate and the springs to the underside or bottom surface 20A of the top plate 10. A TINNERMAN clip (mechanical fastener) located on the push plate (which will be discussed later) is added to each metal pin to secure the push plate from coming off on the downstroke when it is released so that the cleaning cloth which it retains can be discarded.
Referring to FIG. 4, there is illustrated a top perspective view of the push plate 200. The push plate 200 has a top surface 202 which contains thereon along a first side 231 a multiplicity of groups of spaced apart spikes 210 (two spikes), 212 (four spikes), 220 (two spikes), 222 (two spikes), 230 (four spikes) and 232 (two spikes) and adjacent the opposite side 235 a corresponding multiplicity of groups of spaced apart spikes 240 (two spikes), 242 (four spikes), 250 (two spikes), 252 (two spikes), 260 (four spikes) and 262 (four spikes). The purpose of these spikes is so that a cloth can be wrapped around the push plate 200 and retained in a press fit condition by the spikes 210, 212, 220, 222, 230, and 232 and 240, 242, 250, 252, 260, and 262 as will be later discussed. The push plate 200 also has flat housing members 213, 214, 216 and 218 on its upper surface 202 and corresponding flat housing members on its bottom surface as illustrated in FIG. 5. Referring to FIG. 5, there is illustrated a bottom perspective view of the push plate 200 having a bottom surface 242 with corresponding locating surfaces 213, 214, 216 and 218. Instead of being held by spikes, the cloth can be wrapped over the push plate 200 so that cloth is aligned with surfaces 213, 214, 216, and 218. These surfaces are aligned with mating hook fasteners from the bottom of the mechanical plate as will be described later. Also illustrated in FIG. 5 are the TINNERMAN clips (mechanical fasteners) 52 and 62 which will be affixed to the bottom of steel pins 50 and 60 of top plate 20 to keep the push plate 200 from falling away when it is released.
Referring again to FIG. 4, on the top surface 202 of the push plate 200 are a pair of ratchet collars 270 and 280 with a respective sidewall 278 and 288 with each respective sidewall having a respective ratchet notch 272 and 282 into which the end of the linkage of the trigger mechanism will be engaged to overcome a spring force as will be described later. Each ratchet collar 270 and 280 has a respective opening 274 and 284 in a respective top 276 and 286. The openings 274 and 284 respectively extend to interior shafts as will be described below within each ratchet collar and extend through the interior shaft of each respective ratchet collar and extend out of the respective ratchet collars 270 and 280 to the bottom surface 242 of the push plate 200 so that the TINNERMAN clips (mechanical fasteners) 52 and 62 can be affixed to the bottom of the steel pins 50 and 60. The top surface 202 and push plate 200 also have a pair of pins or spring housings 232 and 234 to respectively support a respective compression springs.
Referring to FIG. 5, the bottom 242 of the push plate 200 has a pair of metal TINNERMAN CLIPS (mechanical fasteners) 52 and 62 which are respectively press fit onto the steel pins 50 and 60 for the reasons as will be discussed.
The last component of the present invention is the mechanical plate 400. Referring to FIG. 6 there is illustrated the top of the mechanical plate 400 with openings to receive the components of the push plate and additional mechanical plate components as will be described.
FIG. 6 is a top perspective view of the mechanical plate 400. FIG. 6 discloses female receiving members 32A, 34A, 36A and 38A to respectively receive male mating members 32, 34, 36 and 38 from the bottom of 20A of top plate 10 and female receiving members 42A, 44A, 46A and 48A to respectively receive male mating members 42, 44, 46 and 48 from the bottom 20A of the top plate 10. Opening 231 permits spring housing or retaining post 232 from the push plate 200 to extend therethrough. Opening 271 permits ratchet collar 270 from the push 200 to extend therethrough. Opening 281 permits ratchet collar 280 from the push plate 200 to extend therethrough. Opening 233 permits spring housing or retaining post 232 from the push plate 200 to extend therethrough. The mechanical plate 400 also includes hook member top housings 216T, 218T, 212T and 214T. Referring to FIG. 7, there is illustrated a bottom plan view of the mechanical plate 400. The bottom surface 398 includes hook members 213V, 214V 216V and 218V which are retained underneath respective hook member top housing 213T, 214T, 216T and 216T.
Referring further to FIG. 6, the mechanical plate 400 also has groups of spaced apart spike covers 210C, 212C, 220C, 222C, 230C and 232C adjacent side 201 and groups of spaced apart spike covers 240C, 242C, 250C, 252C 260C and 262C adjacent side 203. When a microfiber cloth 502 is retained by the spikes on the push plate 200, the covers prevent the spikes from penetrating the mechanical plate so that the microfiber cloth 502 is press fit between the spikes and their respective spike covers. When the push plate 200 is against the bottom of the mechanical plate 400, the spikes from the push plate and spikes covers from the mechanical plate are aligned as follows: 210 and 210C; 212 and 212C; 220 and 220C; 222 and 222C; 230 and 230C; 232 and 232C; 240 and 240C; 242 and 242C; 250 and 250C; 252 and 252C; 260 and 262C; and 262 and 262C.
FIG. 8 is a top perspective view of the mechanical plate 400 with components from the push plate 200 pushed therethrough as described in FIG. 6 and including additional operating members of the mechanical linkage. Referring first to FIG. 8A, there is a detailed view of the left linkage 500 illustrated in FIG. 8. The linkage 500 at a first end has a tooth mechanism 510 which extends from the first extension arm 506 and ends in the tooth mechanism 510 which will be inserted into a ratchet notch of a respective ratchet collar. The arm 506 then extends to a central pivot section 520 with a central pivot opening 530. The pivot section 520 then extends into a second arm section 540 which extends to a first stop tooth member 570 which will be described later in this description and on the opposite side it has an arcuate extension 550 which extends into a flat tooth member 560 which will be engaged by the trigger mechanism. Referring to FIG. 8B, the right flexible linkage which is numbered 600 in FIG. 6 is the mirror image of the flexible linkage just described. The parts have numbers which correspond to the left linkage but are numbered in the 600 figure numbers. The linkage 600 at a first end has a tooth mechanism 610 which extends from the first extension arm 606 and ends in the tooth mechanism 610 which will be inserted into a ratchet notch of a respective ratchet collar. The arm 606 then extends to a central pivot section 620 with a central pivot opening 630. The pivot section 620 then extends into a second arm section 640 which extends to a first stop tooth member 670 which will be described later in this description and on the opposite side it has an arcuate extension 650 which extends into a flat tooth member 660 which will be engaged by the trigger mechanism.
The opening 530 as described above is inserted in a pivot pin 580 and the corresponding opposite right linkage and opening 630 is inserted in pivot pin 680.
Referring to FIG. 8, on the mechanical plate 400, there is a first stop wall 410 into which linkage arm 506 is inserted. The first stop wall 410 has an opening 420 into which the arm of the first linkage member 506 is inserted and prevented from further transverse movement. The opposite side has a second stop wall 430 with an opening 440 into which the arm 606 of the second linkage member 600 is inserted. The respective end tooth members 570 and 670 of the respective linkages 500 and 600 are retained by a stop member 640 and are therefore restrained from further transverse movement. The opposite end which contains the teeth as discussed above are inserted into a gap in the trigger mechanism 110. The purpose of the stop member 640 is to limit further advance of the flexible linkage and to give the spring effect to keep the linkages 500 and 600 acting as a spring.
FIG. 9 is a top perspective view illustrating the top plate 10, the mechanical plate 400 and the push plate 200 spaced apart. The microfiber cloth 500 is wrapped over the spikes in the push plate 200. FIG. 10 illustrates the top plate 10, mechanical plate 400 and microfiber cover 500 wrapped around the push plate 500 and retained between the spikes on the push plate and the spike covers on the mechanical plate assembled together in the affixed condition retaining a microfiber cloth. FIG. 10A is a cross sectional view illustrating the top plate 10, mechanical plate 400 and push plate 200 in the cloth retained condition where the springs 800 and 810 extend through openings 231 and 233 in the mechanical plate and the ratchet collars 270 and 280 extends through respective openings 271 and 281 in the mechanical plate so that they appear as shown in FIG. 8. The top plate is assembled onto the assembly so that the pins 50 and 60 extend through openings 274 and 284 in ratchet collars 270 and 280 and extend through shafts 275 and 285 for the pin movable lengths “L1” and L2” of the respective ratchet collars 270 and 280 and extend out of the bottom 277 and 287 of ratchet collars 270 and 280 so that the bottom 50B and 60B of steel pins 50 and 60 are retained by the Tinnerman pins 52 and 62 illustrated in FIG. 10A on the bottom of the push plate. Therefore, the push plate 200 is retained in this way onto the top plate 10 with the mechanical plate 400 sandwiched between them.
Springs 800 and 810 are retained on the retaining posts 60 and 60A from the bottom 8A of the top plate 10. The assembly is held together because the respective tooth 510 of flexible linkage 500 is inserted into notch 272 of notch collar 270 and corresponding tooth 610 of flexible linkage 600 is inserted into notch 282 of notch collar 280 and by this attachment overcomes a downward spring force from springs 800 and 810. When the trigger 110 is pushed inwardly, the flexible linkages rotate about pivot pin 580 and 680 so that the teeth 510 and 610 become disengaged from the notches 272 and 282 and the downward spring force of force springs 800 and 810 cause push plate 200 to move away from the bottom of the mechanical plate 400 by the distance that the steel pins 50 and 60 are in their respective collars 270 and 280 until the respective widened heads 50AA and 60AA hits the respective tops of interior walls 269 an 279 within ratchet collars 270 and 280. Immediately before, a microfiber cloth 500 is held between the spikes on the push plate and spike covers on the mechanical plate as previously discussed. When the trigger is activated as just discussed, the push plate 200 moves away from the mechanical plate 400 by the distances L1 and L2 so the microfiber cloth is released so it can be discarded. This is illustrated in the perspective view of FIG. 11 and the cross sectional view of FIG. 11A.
FIGS. 12, 13, 13A, 14 and 14A illustrated a corresponding embodiment where a non-woven cloth is retained. FIG. 12 is a top perspective view illustrating the top plate 10, the mechanical plate 400 and the push plate 200 spaced apart. The non-woven cloth 510 is wrapped over the push plate 200 so that the non-woven cloth 510 can be retained by the hook members 212V, 214V, 216V and 218V on the bottom of the mechanical plate 400.
FIG. 13 illustrates the top plate 10, mechanical plate 400 and non-woven cloth 510 wrapped around the push plate 500 and retained by the hook members 212V, 214V, 216V and 218V on the mechanical plate assembled together in the affixed condition retaining a non-woven cloth. FIG. 13A is a cross sectional view illustrating the top plate 10, mechanical plate 400 and push plate 200 in the non-woven cloth in the retained condition where the springs 800 and 810 extend through openings 231 and 233 in the mechanical plate and the ratchet collars 270 and 280 extends through respective openings 271 and 281 in the mechanical plate so that they appear as shown in FIG. 8. The top plate is assembled onto the assembly so that the pins 50 and 60 extend through openings 274 and 284 in ratchet collars 270 and 280 and extend through shafts 275 and 285 for the movable lengths “L1” and L2” of the respective ratchet collars 270 and 280 and extend out of the bottom 277 and 287 of ratchet collars 270 and 280 so that the bottom 50B and 60B of steel pins 50 and 60 are retained by the Tinnerman pins 52 and 62 illustrated in FIG. 10A on the bottom of the push plate. Therefore, the push plate 200 is retained in this way onto the top plate 10 with the mechanical plate 400 sandwiched between them.
As illustrated in FIG. 8, the left linkage 500 has its tooth 510 inserted into notch 272 of notch collar 270 and the tooth 610 of right linkage 600 is inserted into notch 282 of notch collar 280. There is also a first compression spring 800 and a second compression spring 810 which respectively rest around on spring housing or supporting posts 232 and 234 which are illustrated in FIG. 4. The springs are retained in the underside of the top plate 20A by post members 60 and 60A so that each respective spring 800 and 810 is retained in the bottom of the stationary top plate as best illustrated in FIG. 3A. As best illustrated in the top plan view of FIG. 4, ratchet collar 270 has a top opening 274 on its top 276 and ratchet collar 280 has a top opening 284 on its top 286. Therefore, when respective posts 50 and 60 are inserted into the openings 274 and 284 of ratchet collars 270 and 280, they extend to the bottom of the collar and are retained by the TINNERMAN clips (mechanical fasteners) illustrated in FIG. 5 numbers 52 and 62. Therefore, the travel distance that the push plate 200 can make is the length of the pins 50 and 60 within collars 270 and 280. When assembled, the top plate 10 is inserted into the mechanical plate 400 by having the respective pins or posts 50 and 60 respectively inserted into notch collar openings 274 and 284 of respective notch collars 270 and 280 and then the push plate 200 is affixed by having the respective spring collars affixed to the bottom of the top plate as previously discussed and having the TINNERMAN clips (mechanical fasteners) 52 and 62 respectively affixed onto the ends of pins 50 and 60 to affix the push plate 200 to the bottom of the top plate 10 with the mechanical plate 400 between the top plate 10 and push plate 200.
FIG. 9 is a top perspective view illustrating the top plate 10, the mechanical plate 400 and the push plate 200 spaced apart. The microfiber cloth 502 is wrapped over the spikes in the push plate 200. FIG. 10 illustrates the top plate 10, mechanical plate 400 and microfiber cloth 502 wrapped around the push plate 200 and retained between the spikes on the push plate and the spike covers on the mechanical plate assembled together in the affixed condition retaining a microfiber cloth 502. FIG. 10A is a cross sectional view illustrating the top plate 10, mechanical plate 400 and push plate 200 in the cloth retained condition where the springs 800 and 810 extend through openings 231 and 233 in the mechanical plate and the ratchet collars 270 and 280 extend through respective openings 271 and 281 in the mechanical plate so that they appear as shown in FIG. 8. The top plate is assembled onto the assembly so that the pins 50 and 60 extend through openings 274 and 284 in ratchet collars 270 and 280 and extend through shafts 275 and 285 for the pin movable lengths “L1” and “L2” of the respective ratchet collars 270 and 280 and extend out of the bottom 277 and 287 of ratchet collars 270 and 280 so that the bottom 50B and 60B of steel pins 50 and 60 are retained by the TINNERMAN CLIPS (mechanical fasteners) 52 and 62 illustrated in FIG. 10A on the bottom of the push plate. Therefore, the push plate 200 is retained in this way onto the top plate 10 with the mechanical plate 400 sandwiched between them.
Springs 800 and 810 are retained on the retaining posts 60 and 60A from the bottom 8A of the top plate 10. The assembly is held together because the respective tooth 510 of flexible linkage 500 is inserted into notch 272 of notch collar 270 and corresponding tooth 610 of flexible linkage 600 is inserted into notch 282 of notch collar 280 and by this attachment overcomes a downward spring force from springs 800 and 810. When the trigger 110 is pushed inwardly, the flexible linkages rotate about pivot pin 580 and 680 so that the teeth 510 and 610 become disengaged from the notches 272 and 282 and the downward spring force of force springs 800 and 810 cause push plate 200 to move away from the bottom of the mechanical plate 400 by the distance that the steel pins 50 and 60 are in their respective collars 270 and 280 until the respective widened heads 50AA and 60AA hits hit the respective tops of interior walls 269 and 279 within ratchet collars 270 and 280. Immediately before, a microfiber cloth 502 is held between the spikes on the push plate and spike covers on the mechanical plate as previously discussed. When the trigger is activated as just discussed, the push plate 200 moves away from the mechanical plate 400 by the distances L1 and L2 so the microfiber cloth 502 is released so it can be discarded. This is illustrated in the perspective view of FIG. 11 and the cross sectional view of FIG. 11A.
FIGS. 12, 13, 13A, 14 and 14A illustrate a corresponding embodiment where a non-woven cloth is retained. FIG. 12 is a top perspective view illustrating the top plate 10, the mechanical plate 400 and the push plate 200 spaced apart. The non-woven cloth 514 is wrapped over the push plate 200 so that the non-woven cloth 514 can be retained by the hook members 213V, 214V, 216V and 218V on the bottom of the mechanical plate 400.
FIG. 13 illustrates the top plate 10, mechanical plate 400 and non-woven cloth 510 wrapped around the push plate 200 and retained by the hook members 213V, 214V, 216V and 218V on the mechanical plate assembled together in the affixed condition retaining a non-woven cloth. FIG. 13A is a cross sectional view illustrating the top plate 10, mechanical plate 400 and push plate 200 in the non-woven cloth in the retained condition where the springs 800 and 810 extend through openings 231 and 233 in the mechanical plate and the ratchet collars 270 and 280 extend through respective openings 271 and 281 in the mechanical plate so that they appear as shown in FIG. 8. The top plate is assembled onto the assembly so that the pins 50 and 60 extend through openings 274 and 284 in ratchet collars 270 and 280 and extend through shafts 275 and 285 for the movable lengths “L1” and L2” of the respective ratchet collars 270 and 280 and extend out of the bottom 277 and 287 of ratchet collars 270 and 280 so that the bottom 50B and 60B of steel pins 50 and 60 are retained by the TINNERMAN clips (mechanical fasteners) 52 and 62 illustrated in FIG. 10A4 on the bottom of the push plate. Therefore, the push plate 200 is retained in this way onto the top plate 10 with the mechanical plate 400 sandwiched between them.
Springs 800 and 810 are retained on the retaining posts 60 and 60A from the bottom 8A of the top plate 10. The assembly is held together because the respective tooth 510 of flexible linkage 500 is inserted into notch 272 of notch collar 270 and corresponding tooth 610 of flexible linkage 600 is inserted into notch 282 of notch collar 280 and by this attachment overcomes a downward spring force from springs 800 and 810. When the trigger 110 is pushed inwardly, the flexible linkages rotate about pivot pin 580 and 680 so that the teeth 510 and 610 become disengaged from the notches 272 and 282 and the downward spring force of force springs 800 and 810 cause push plate 200 to move away from the bottom of the mechanical plate 400 by the distance that the steel pins 50 and 60 are in their respective collars 270 and 280. At that point, a non-woven cloth 510 is held by the hooks between the mechanical plate and push plate as previously discussed. When the trigger is activated as just discussed, the push plate 200 moves away from the mechanical plate 400 by the distances L1 and L2 until the widened pin tops hit the respective tops of the interior ratchet walls 269 and 279 so that the non-woven cloth is pulled away from the hooks 213V, 214V, 216V and 218V and is released so it can be discarded. This is illustrated in the perspective view of FIG. 14 and the cross sectional view of FIG. 14A.
