1. Field of the Invention
The present invention relates to the field of hand operated sweeping mops which retain a disposable cleaning cloth.
2. Description of the Prior Art
In general, various types of hand operated sweeping mops are known in the prior art.
The hand operated sweeping mops include a generally rectangular shaped main body having an upper or top surface which includes a rotatable yolk attached to a collar having an opening which receives an elongated handle which is grasped by a user when operating the sweeping mop.
The main body also has a flat lower or bottom surface with a disposable cleaning cloth affixed to the sweeping mop applicator so that the disposable cleaning cloth is positioned under the lower or bottom surface and is retained onto the main body by various different retaining members.
In one retaining member configuration, the lower surface of the main body has hook and loop fasteners affixed to the lower surface and the disposable cleaning cloth is retained onto the lower surface of the main body by the hook and loop fasteners. In another configuration, the disposable cleaning cloth is retained onto the main body by several attachment members usually positioned on the upper surface on opposite sides of the yolk so that the disposable cleaning cloth is wrapped around the outer circumference of the main body and then attached by the attachment members to the sweeping mop.
One common problem with all prior art hand operated sweeping mop applicators also called flat mop applicators is that when the disposable cloth is very dirty after cleaning operations, the user must use at least one of his/her hands to grasp the dirty cleaning cloth and remove it from its attachment member on the sweeping mop applicator also called a flat mop applicator. Therefore, the user is exposed to the filth and dirt on the disposable cleaning cloth. There is a significant need for an improved apparatus which eliminates the requirement for a user to grasp the dirty cleaning cloth by hand when removing it from the sweeping mop applicator or flat mop applicator and replacing it.
The present invention is a hand operated sweeping mop applicator with a unique disposable cloth retaining assembly where the cloth is retained by cloth retaining members attached to the bottom of a top plate which extend perpendicularly away from a bottom of the top plate and extend through aligned openings in a bottom plate to retain a cleaning cloth against a bottom surface of the bottom plate. Closing force members such as force springs are sandwiched between the bottom of the top plate and the top of the bottom plate and retained in a compressed state to retain the top plate and bottom plate together.
The shotgun plate separation member includes an engaging assembly having an open cylindrical member by which it is rotatably retained between two yoke members on the top surface of the top plate to enable the handle to rotate back and forth in a given direction. The engaging assembly includes an intermediate “H” shaped connector rotatably connected to the open cylindrical member so that the handle can also rotate in a direction perpendicular to the direction of rotation of the open cylindrical member rotatably retained between the two yoke members. The engagement assembly also includes a top cylindrical hollow collar having a transverse opening in the cylindrical wall and a top rim.
The shotgun further includes an elongated cylindrical metal shaft having a transverse opening adjacent its lower proximal end, the upper end of the elongated cylindrical metal shaft is covered by a covering member having a multiplicity of spaced apart longitudinal ribs and terminating in a stop ring on the elongated cylindrical metal shaft to prevent axial movement on the covering member beyond the stop ring. A lower housing has a hollow interior with an interior surface having a multiplicity of interior longitudinal shafts which correspond to the exterior ribs on the covering member so that when the lower exterior housing is placed over the elongated cylindrical metal shaft and a portion of the covering member, the aligned ribs and shafts prevent rotation of the exterior housing about the elongated cylindrical metal shaft and covering member. A retaining force spring surrounds a portion of the elongated cylindrical metal shaft and is press fit retained between a distal end of the covering member and the upper rim of the collar of the engagement member. A C-clip inserted through aligned transverse openings in the elongated cylindrical metal shaft and collar of the engagement member retains the engagement member to the elongated cylindrical metal shaft with the retaining force spring retained in a compressed state. The lower housing has a multiplicity of feet which respectively receive posts which extend perpendicularly from the bottom plate and through the top plate. In its at rest condition, the retaining force spring causes the lower housing to be axially pulled away from the top and bottom plates until axial movement is restrained by the stop ring
The lower outer housing is separated from the stop ring by a given distance. In its at rest condition, the lower housing member is pulled upwardly or axially on the covering member by the retaining force spring until it reaches the stop ring. The upward pulling force causes the aligned feet in the lower housing to be separated from the four aligned posts on the bottom plate which respectively extend through respective openings on the top plate. The retaining springs between the top plate and the bottom plate cause the two plates to be retained together. In operation, a downward pushing force on the lower housing of the shotgun assembly causes the four aligned feet to be respectively aligned with the four posts so that the pushing force overcomes the retaining force of the retaining spring in the shotgun assembly and pushes downwardly on the bottom plate to also overcome the retaining force of the internal force spring between the top plate and bottom plate. As a result, the retaining force is overcome and the pushing force from the feet of the lower housing on the aligned posts cause the bottom plate to be separated from the top which disengages the cloth retaining members on the bottom surface of the top plate from the cleaning cloth and enables the cleaning cloth to fall away from the bottom surface of the bottom plate without having to be touched with a person's hand.
When the pushing force on the lower housing is released, the interior retaining spring forces the lower housing axially away from the top plate until movement is restrained by the stop ring so that the four feet of the lower housing are respectively disengaged from a respective post to cause the top and bottom plates to be compressed together by the retaining force springs between the two plates so that a new cloth can be retained against the bottom of the bottom plate by the retaining member extending from the bottom of the top plate through aligned openings in the bottom plate to come in contact with and retain the cleaning cloth. The downward pushing force on the lower exterior housing and its automatic return motion from the upward return force of the internal retaining force spring when the pushing force on the lower housing is released resembles a shotgun.
It is an object of the present invention to provide a mechanism on a hand operated sweeping mop applicator which retains a cleaning cloth in a manner which enables the cleaning cloth after it has been used and becomes dirty to be released and fall into a trash receptacle without the necessity of a user's hand touching the dirty cleaning cloth.
It is also an object of the present invention to provide a mechanism for a hand operated sweeping mop applicator which includes a pushing force to push downwardly on a plate against which a cloth is retained to force a downward motion to separate an upper plate having cloth retaining means from the lower plate against which the cloth is retained by the cloth releasing means in the upper plate to enable the dirty cleaning cloth to be separated from the cloth retaining means so that when the connection is released, the cleaning cloth is released without requiring a human hand to touch a dirty cleaning cloth.
It is an additional object of the present invention to provide a mechanism which limits the downward travel of a cloth releasing plate so that it will not fall away from the main body of the sweeping mop applicator.
It is a further object of the present invention to provide a shotgun mechanism to permit the plates of the applicator to remain together and then by a pushing force on the shotgun mechanism causes a separation of the two plates to release the retaining force from a top plate on a cleaning cloth to enable the cleaning cloth top to be released without being touched by a hand.
