ABSTRACT:
BACKGROUND OF THE INVENTION
In some countries of the world, floor-drains are provided in the floor of residences, hotels, and the like, by which the floor may be washed clean using water, and pushing the water along the floor surface while directing it to a generally centrally-located drain-hole by which the dirty water may be drained away. Typically, one pours the water, either with or without a cleaning agent, onto the floor, and then pushes the poured water along the floor toward the drain-hole using a conventional floor squeegee, sponge mop, or cotton-strand mop, and the like. However, since the drain-hole provided in the floor is usually provided at the bottom of a generally diminutively-sized depression, pushing the dirty water toward and into the drain-hole is a relatively tedious and time-consuming task, since as one pushes the dirty water thereat, the water will overshoot or miss the generally diminutively-sized depression containing the drain-hole. Thus, multiple attempts at pushing the water into the drain-hole is necessary.
SUMMARY OF THE INVENTION
It is, therefore, the primary objective of the present invention to provide a method and device that will aid persons in directing the dirty water being pushed along the horizontal floor-surface toward and into the drain-hole of the floor.
It is another objective of the present invention to provide a method and device that will aid persons in directing dirty water being pushed along the horizontal floor-surface toward and into the drain-hole of the floor, which device is portable and removable, and which is easily insertable into a conventional drain-hole of a floor.
It is yet another objective of the present invention to provide a method and device that will aid persons in directing dirty water being pushed along the horizontal floor-surface toward and into the drain-hole of the floor, which device is portable and removable, and which is easily insertable into a conventional drain-hole of a floor, and which is adjustable in order to accommodate various-sized and dimensioned pushing tools for pushing the dirty water toward and into the drain-hole.
Toward these and other ends, the device of the present invention is provided with a main housing-insert which is capable of being inserted into the opening of a conventional drain-hole of a floor. The housing-insert is preferably frustoconical is shape, in order to be received in different and variously sized drain-holes. Attached to the housing-insert is a pair of elongated, water-deflecting leg-members. Each leg-member is attached at one end thereof to an upper portion of the housing-insert. The other ends of the legs extend outwardly in cantilever fashion. The two leg-members form an angle therebetween from their extension from the housing-insert, with the drain-hole contained within the space between the leg-members. Each leg-member is provided, preferably, with a downwardly-projecting, elongated rubber or squeegee-like deflecting member extending, preferably, at least most of the length of the respective leg, which deflecting member contacts the floor-surface to prevent the flowing water from flowing therepast. In the preferred embodiment of the invention, the leg-members are pivotally connected at their one ends to the housing-insert. In another embodiment, the ends of the leg-members need not be connected to the housing-insert, but need only be supported thereon.
