Sponge roller mop with quick release mechanism to remove a dirty sponge from the housing without having to touch the dirty or contaminated sponge

摘要

A mechanism by which the mop of a sponge roller mop is released without a user having to touch a dirty mop so that the sponge can be released and replaced with a clean sponge, including a sponge pin molded onto the brace which retains the sponge. The mechanism includes a transverse section with a movable hole through which the crown from the sponge pin is inserted. The wall is moved by a transverse spring force so that the wall from the opening of the trigger mechanism is placed between the crown and a lower section of the sponge pin to thereby retain the crown within the rod retaining mechanism. When a pushbutton is pushed transversely, it overcomes the spring force so that the crown is released and a downward force from the vertical compression spring forces the crown downwardly and out of the trigger mechanism, thereby releasing the sponge.

主权项

1. A sponge roller mop including a sponge retained by a brace, a first roller and a spaced apart second roller, a mop handle surrounding an interior elongated rod, a lever wringer rotatably engaged to the elongated mop handle and connected to the elongated rod, the sponge mop comprising:
a. a sponge pin molded onto the brace so that the sponge pin extends away from the brace, the sponge pin having a first section integral with a wide section molded onto the brace, a second narrower section, a third narrowest section and a crown having a lower surface, a gap between the lower surface of the crown and the second narrower section, the gap centered by the third section; b. the brace including a first front stopping member and a spaced apart second front stopping member engaging the first roller and a first rear stopping member and a spaced apart second rear stopping member engaging the second roller; c. a trigger release mechanism including an exterior vertical housing surrounding an interior vertical chamber having a fixed rod connector, a first movable vertical piston and a first vertical compression spring between the fixed rod connector and the first movable vertical piston, a transverse housing surrounding a transverse interior chamber, a pushbutton extending into the transverse interior chamber, the pushbutton including a distal end and a proximal end within the transverse interior chamber, the pushbutton having an opening and an opening circumferential sidewall extending through the pushbutton at a location adjacent its proximal end, the transverse housing including a transverse wall with an interior surface, a transverse compression spring retained between the interior surface of the transverse wall and the proximal end of the pushbutton; d. the sponge pin inserted through the opening in the pushbutton and the transverse compression spring in an uncompressed condition exerting a force causing the circumferential sidewall of the opening to be lodged in the gap of the sponge pin to lock the sponge pin and causing the first vertical compression spring to be in a compressed condition; e. the lever wringer is moved to a position to disengage the brace from the rollers and then a transverse force at the distal end of the pushbutton overcomes the force of the transverse compression spring causing the opening in the pushbutton to move and disengaging the sponge pin from the circumferential sidewall of the opening in the pushbutton, the crown is aligned with the movable piston and a force of the vertical compression spring causes the sponge pin to be ejected by the trigger mechanism also ejecting the brace and the sponge; and f. the trigger mechanism is retained within the housing which has a body with a vertical cutout through which the pushbutton is accessible.
