The present invention relates to the field of hand-operated flat mops which retain a disposable cleaning cloth used to scrub and clean surfaces such as floors.
The present inventor Fred I. Morad is a co-inventor of the invention entitled U.S. Pat. No. 8,800,092 for “APPARATUS TO REMOVE A DISPOSABLE CLOTH FROM A HAND OPERATED FLAT MOP THROUGH A SINGLE TRIGGER MECHANISM WITHOUT HAVING TO TOUCH THE DISPOSABLE CLOTH” issued on Aug. 12, 2014.
The present inventor Fred I. Morad is also aware of pending patent application Ser. No. 14/596,325, Publication No. 2015/0208893 filed by Stephens et al. for “APPARATUS AND METHOD FOR PREPARING A SURFACE”.
The present invention is a dual trigger mechanism to release a disposable microfiber cloth or non-woven cloth from a flat mop combined with a ball and socket assembly. The present invention includes one or more of the following components or features: (1) a socket affixed to a handle and a ball affixed to a top plate of the mop with the socket movably grasping the ball; (2) a top plate; (3) a mechanical plate with a dual trigger mechanism incorporated into the mechanical plate; (4) a push plate; and (5) a pad made of material such as foam or rubber below the push plate. In one variation, the invention retains a microfiber cloth, a wiping material, a cleaning material or cloth made out of similar material. In an alternative variation, the invention retains a non-woven cloth or cloth made out of similar material.
The top plate is stationary with respect to other components and provides a base to which the other components are coupled. It has a flat top surface with a ball located at a center of the top plate. The ball is attached to a cylindrical stem or comparable ball extension member which extends through a central opening in the top plate. The extension member and the opening in the top cover, in one embodiment, are the same shape or similar shape to provide a cooperative interaction therebetween. If the extension member is not round, then the opening in the top plate is configured to be able to receive the extension member. The ball extension member is held in place by at least one grasping member within the central opening and the extension member is fixed in place, with an adhesive, threads, or connector, for instance, in place in the central opening in the top plate and/or the ball is fixed to the top surface of the top plate. The ball removably receives a socket affixed to the bottom of the mop handle. When the socket engages the ball, the mop handle is able to rotate three-hundred sixty (360) degrees in one or more directions with respect to the top plate. Therefore, a user grasping the handle can push and pull the mop back and forth in any direction when cleaning a flat surface such as a floor.
The top plate also includes spaced apart trigger activation member or squeeze member openings spaced at opposite sides of the ball and extending through the thickness of the top plate. In one embodiment, the squeeze member openings are equidistant on opposite sides of the ball. A first trigger activation member extends through a first activation member opening and a second trigger activation member extends through a second activation member opening. Each trigger activation member extends at or near perpendicular with respect to the upper surface of the top plate. The first and second trigger activation members are substantially parallel to each other. Each respective trigger mechanism opening is sufficiently wide to enable each respective trigger mechanism to be pushed toward the ball, or alternatively squeezed between two fingers to push each respective trigger activation member toward the ball.
The top plate also includes a first ratchet collar cover located on the same side as and spaced apart from the first trigger activation member opening, and closer to the first end of the top plate. The top plate also includes a second ratchet collar cover located on the same side as and spaced apart from the second trigger activation member opening, and closer to the second end of the top plate. Each respective ratchet collar cover is respectively spaced apart from a respective trigger activation member opening and each is further away from the ball.
The top plate has a bottom surface which includes a first compression spring housing supporting the top of a first compression spring and a second compression spring housing supporting the top of a second compression spring.
The push plate is designed to facilitate the retention of the wiping cloth, such as the microfiber cloth or non-woven cloth and facilitate the removal of a dirty cloth without a user's hand touching the cloth. There are different variations of the push plate. Each variation includes some of the same components. Affixed to the top surface of the push plate is a first ratchet collar vertically aligned with the first ratchet collar cover of the top plate and spaced apart from the first operating trigger assembly of the first trigger mechanism on the mechanical plate. The first ratchet collar has a sidewall with a first ratchet notch which receives a first notch tooth from the first trigger mechanism. The first ratchet collar extends through aligned openings in the mechanical plate and the top plate and is received in the first ratchet collar cover on the top plate. Similarly, affixed to the top surface of the push plate is a second ratchet collar vertically aligned with the second ratchet collar cover of the top plate and spaced apart from the second operating trigger assembly of the second trigger mechanism on the mechanical plate. The second ratchet collar has a sidewall with a second ratchet notch which receives a second notch tooth from the second trigger mechanism. The second ratchet collar extends through aligned openings in the mechanical plate and the top plate and is received in the second ratchet collar cover on the top plate.
Affixed to the top surface of the push plate and spaced apart from the first ratchet collar is a first bottom compression spring housing retaining the bottom of the first compression spring extending through an aligned first spring opening in the mechanical plate and retained in the vertically aligned first top compression spring housing on the bottom surface of the top plate. Similarly, affixed to the top surface of the push plate and spaced apart from the second ratchet collar is a second bottom compression spring housing retaining the bottom of the second compression spring extending through an aligned second spring opening in the mechanical plate and retained in the vertically aligned second top compression spring housing on the bottom surface of the top plate.
A first mechanical fastening member (such as a fastening pin) has a top end and a bottom end and extends from its bottom end affixed within the push plate and extends through the push plate, through an aligned opening in the mechanical plate and into an aligned opening within the first ratchet collar and having its top end retained within the first ratchet collar.
Similarly, a second mechanical fastening member (such as a fastening pin) has a top end and a bottom end and extends from its bottom end affixed within the push plate and extends through the push plate, through an aligned opening in the mechanical plate and into an aligned opening within the second ratchet collar and having its top end retained within the second ratchet collar.
A first pin retaining member (such as a Tinnerman Clip) retains the first mechanical fastening member at the bottom surface of the push plate and within the first ratchet collar and a second pin retaining member (such as a Tinnerman Clip) retains the second mechanical fastening member at the bottom surface of the push plate and within the second ratchet collar.
The variations on the push plate have the following differences. In a first variation, the push plate facilitates the retention of a microfiber cloth and has a multiplicity of openings to enable microfiber cloth retention members extending from the bottom of the mechanical plate to engage and retain the microfiber cloth. In one embodiment of the present invention, there are six openings, three in one row and three in an opposite parallel row with an opening in one row aligned with an opening in the second row. Six respective aligned posts each having a mating hook fastener at its distal end extending from the bottom surface of the mechanical plate through a respective opening in the push plate to retain the microfiber cloth.
In the first variation of the push plate, a bottom surface has a multiplicity of ribs to facilitate retention of a pad such as a rubber or foam pad with adhesive applied to the ribs against the bottom surface of the push plate. The rubber or foam pad has a multiplicity of openings respectively aligned with the openings in the push plate to enable the microfiber cloth retention members to extend through the pad and to engage and retain the microfiber cloth.
In the second variation, the top surface of the push plate has a multiplicity of aligned teeth adjacent respective parallel longitudinal sides of the push plate and corresponding with aligned openings in the bottom of the mechanical plate. A non-woven cloth is wrapped around the push plate, partially retained by the aligned parallel rows of teeth and retained by a press fit between the push plate and the mechanical plate.
The last component is the mechanical plate which is stationary and affixed to the bottom of the top plate. A first ratchet collar opening in the mechanical plate enables the first ratchet collar to extend through this aligned opening in the mechanical plate and rest within the first ratchet collar cover and a second ratchet collar opening in the mechanical plate enables the second ratchet collar to extend through this aligned opening in the mechanical plate and rest within the second ratchet collar cover.
A first compression spring opening in the mechanical plate enables the first compression spring to extend from the first bottom compression spring housing on the push plate through the first compression spring opening in the mechanical plate into the first top compression spring housing on the top plate. Similarly, a second compression spring opening in the mechanical plate enables the second compression spring to extend from the second bottom compression spring housing on the push plate through the second compression spring opening in the mechanical plate into the second top compression spring housing on the top plate.
The top surface of the mechanical plate includes a first trigger mechanism having a first “L”-shaped member with an upper portion extending through a first trigger activation mechanism opening in the top to enable the upper portion of the first “L”-shaped member to extend perpendicular to the top plate. The horizontal portion of the first “L”-shaped member extends to engage a first transverse trigger mechanism spring member, is further aligned with a first stop member on the top surface of the mechanical plate and at its end forms a first notch tooth which extends into the first ratchet notch of the first ratchet collar. Similarly, the second trigger mechanism includes a second “L”-shaped member with an upper portion extending through a second trigger activation mechanism opening in the top plate to enable the upper portion of the second “L”-shaped member to extend perpendicular to the top plate. The horizontal portion of the second “L”-shaped member extends to engage a second transverse trigger mechanism spring member, is further aligned with a second stop member on the top surface of the mechanical plate and at its end forms a second notch tooth which extends into the second ratchet notch of the second ratchet collar.
The mechanical plate is retained into or onto the top plate by mating notch and tooth members along the bottom wall of the top plate and along exterior portions of the mechanical plate.
In operation, the first transverse spring member forces the first notch tooth into the first ratchet notch of the first ratchet collar and the second transverse spring member forces the second notch tooth into the second ratchet notch of the second ratchet collar.
A concurrent squeezing force of the upper “L”-shaped members of the first and second trigger activation members forcing the first trigger activation member to move toward the center ball and forcing the second trigger activation member to move toward the center ball, concurrently causing the first ratchet tooth to be removed from the first ratchet notch of the first ratchet collar and the second ratchet tooth to be removed from the second ratchet notch of the second ratchet collar. The force of the first compression spring and the second compression spring forces the push plate to move away from the mechanical plate. The cloth which was retained against the bottom surface of the push plate by either being retained by the hook fasteners for a microfiber cloth or retained by being wrapped around the push plate and press fit retained between the push plate and the mechanical plate for a non-woven cloth is released and the retention force, either hook or press-fit is removed and the cloth falls away to a trash receptacle.
Also described, when the upper portion of each “L”-shaped member of the dual trigger activation mechanism is pushed inwardly toward the ball, each respective transverse trigger mechanism spring member bows inwardly away from a respective ratchet collar and is placed into tension and at the same time each respective ratchet tooth is removed from the respective ratchet notch in the respective ratchet collar. As a result, the force which retained the compression springs under compression is removed and the compression springs which were in a compressed state move to an uncompressed state, causing the push plate to move away from the mechanical plane by a given distance thereby releasing the retention force which retained the cloth and the cloth falls away. The push plate does not complete fall away from the mechanical plate but instead is retained a short distance “D-1” from the mechanical plate by the two fastening pins extending from the bottom surface of the push plate to being retained in a respective ratchet collar. The distance “D-1” is sufficient to disengage the hook fasteners from the microfiber cloth so that the microfiber cloth falls away and is also sufficient to release the press fit between the push plate and the mechanical plate so the non-woven cloth falls away, without a user having to touch the dirty cloth.
When a new cloth is retained against the bottom of the push plate, the pushing force on the upper portion of each “L”-shaped member of the trigger mechanism is released, the tension force on each respective transverse trigger mechanism spring member is released and each respective transverse mechanism spring member bows outwardly toward each respective ratchet collar and each respective ratchet tooth engages into the respective ratchet notch in each respective ratchet collar and the new cloth is retained against the bottom of the push plate.
It is therefore provided in a least one embodiment of the present invention to combine a ball affixed to the mop top plate and a socket affixed to a handle with a mop having a dual release trigger mechanism as described above to enable a dirty cloth to be released from the mop without a user touching the dirty cloth. While a ball is generally described herein, other spheres or spheroids are contemplated.

Referring to FIGS. 4A1 and 4A2, there is illustrated two top views of mechanical plate 100. FIG. 4A1 illustrates the top view of mechanical plate 100 illustrating a first or left trigger assembly 102 having a left central shaft 104 with left central shaft 104 having a left upper wing 107 and a left lower wing 108 that extend generally perpendicular and away from left central shaft 104. Left central shaft 104 is also slidably affixed to top mechanical surface 130 of mechanical plate 100 by left trigger assembly housing 106. Left central shaft 104 and left upper wing 107 and a left lower wing 108 are formed from a flexible material such as spring plastic to allow left upper wing 107 and a left lower wing 108 to bend and store potential energy when left trigger 110 is pressed inwardly towards right trigger 120.
Similarly, FIG. 4A1 also illustrates the top view of mechanical plate 100 illustrating a second or right trigger assembly 112 having a right central shaft 114 with right central shaft 114 having a right upper wing 117 and a right lower wing 118 that extend generally perpendicular and away from right central shaft 114. Right central shaft 114 is also slidably affixed to top mechanical surface 130 of mechanical plate 100 by right trigger assembly housing 116. Right central shaft 114 and right upper wing 117 and a right lower wing 118 are formed from a flexible material such as spring plastic to allow right upper wing 117 and a right lower wing 118 to bend and store potential energy when right trigger 120 is pressed inwardly towards left trigger 110.
In operation, when left trigger 110 and right trigger 120 (which have also been referred to as first trigger activation member 110 and second trigger activation member 120) are pressed inward together, shaft left end 105 and shaft right end 115 move inward and out of respective ratchet collar notches 205 and 215, left ratchet collar 222 and right ratchet collar 224 thereby exposing entirely left mechanical plate ratchet hole 148 and right mechanical plate ratchet hole 158. When left mechanical plate ratchet hole 148 and right mechanical plate ratchet hole 158 are entirely exposed and not covered by any portion of shaft left end 105 and shaft right end 115 as illustrated in FIG. 4A2, left compression spring 262 and right compression spring 264 are allowed to expand from their respective compressed states to force upper push plate 200 and lower push plate 300 to expand to a position approximately 2 inches below top cover 30. In other embodiments, other distances are contemplated. This is best illustrated by
Simultaneously occurring with the inward movement of left trigger assembly 102 and right trigger assembly 104 when left trigger 110 and right trigger 120 are pressed inwardly is the bending of left upper wing 107, left lower wing 108, right upper wing 117, and right lower wing 118. This bending is caused by the inward force acting upon left trigger assembly 102 and right trigger assembly 104 which causes all four wing walls to bend around left stoppers 142A, 142B, 142C, 142D and right stoppers 152A, 152B, 152C, and 152D. All four wings transition from a convex resting position when dual triggers are at a resting outer position (illustrated in FIG. 4A1) to an inward concave position (illustrated in FIG. 4A2) when left trigger 110 and right trigger 120 are pressed inwardly. When left trigger 110 and right trigger 120 are released, all four wings exercise a spring force to return left trigger assembly 102 and right trigger assembly 104 to their initial resting outer position (illustrated in FIG. 4A1).
Referring to FIGS. 4A2 and 4B, there is illustrated a top view of mechanical plate 100 and a bottom view of mechanical plate 100 respectively. FIG. 4A2 illustrates a multiplicity of cloth retaining members 180A, 180B, 180C, 180D, 180E and 180F to enable a cloth to be retained by hook fasteners. Each respective distal end of cloth retaining members 180A, 180B, 180C, 180D, 180E and 180F have cloth retaining ends 182A, 182B, 182C, 182D, 182E and 182F that is made of either a hook material or a fastener material, also known as hook or loop fasteners and pile fasteners.
