ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an innovative structure of brush, which is equipped with a wiper for removing water from windowpanes, decks, floors, etc., and which enables the user to replace the cover cloth thereof.
A variety of brushes have been disclosed for cleaning, and have appeared on the market. Regular brushes for this purpose are commonly comprised of a handle, and hairs, bristles, wires, etc., fastened into the handle. There is known a kind of brush comprised of a casing, a sponge fastened to the casing. Because the sponge is directly rubbed against the object to be cleaned, the sponge tends to be forced away from the casing or damaged during cleaning. Further, when cleaning the house, room, etc., a wiper may be used to remove water from windowpanes, decks, floors, etc.
SUMMARY OF THE INVENTION
It is one object of the present invention to provide a sponge base brush, which uses a replaceable cover cloth to protect the sponge. It is another object of the present invention to provide a sponge base brush, which is equipped with a wiper for removing water from windowpanes, decks, floors, etc. According to one aspect of the present invention, the brush comprises a casing, the casing comprising a top receiving chamber, and two sliding rails longitudinally provided at two opposite lateral sides thereof, a sponge mounted in the top receiving chamber in the casing, a piece of cover cloth covered on the sponge, a rectangular open frame covered on the top receiving chamber of the casing around the sponge to hold down the piece of cover cloth, the rectangular open frame comprising two rows of ribs longitudinally aligned at two opposite sides thereof, and two sliding locking plates respectively coupled to the sliding rails at the casing and moved along the sliding rails to lock the rectangular open frame, the sliding locking plates each comprising a first longitudinal sliding groove coupled to one sliding rail at the casing, a second longitudinal sliding groove arranged in parallel to and spaced above the first longitudinal sliding groove for receiving one row of ribs at the rectangular open frame, and a plurality of transverse notches respectively perpendicularly extended from the second longitudinal sliding groove corresponding to the ribs at one side of the rectangular open frame for enabling the ribs of the rectangular open frame to be respectively engaged into the second longitudinal sliding groove at each of the sliding locking plates. According to another aspect of the present invention, the rectangular open frame has a substantially u-shaped cross section fitting the periphery of the top receiving chamber of the casing, enabling a part of the piece of cover cloth to be retained between an inner side wall of the rectangular open frame and the periphery of the casing. According to still another aspect of the present invention, the first sliding groove at each of the sliding locking plates has one end closed. According to still another aspect of the present invention, the sliding locking plates each comprise a locating notch, and the casing comprises two hooks at the two opposite lateral sides thereof for hooking in the locating notch at each of the sliding locking plates to limit backward movement of the sliding locking plates on the sliding rails at the casing. According to still another aspect of the present invention, the casing comprises a first coupling groove and a second coupling groove respectively disposed in the recessed bottom chamber at two opposite ends, two pairs of plug holes respectively disposed at two opposite sides of the coupling grooves in the recessed bottom chamber, a first locating member and a second locating member respectively fastened to the plug holes and disposed around the coupling grooves in the recessed bottom chamber, a wiper holder coupled between the coupling grooves in the recessed bottom chamber, a rubber blade fastened to the wiper holder and turned with the wiper holder between a vertical position where the rubber blade is disposed outside the recessed bottom chamber and a horizontal position where the rubber blade is received inside the recessed bottom chamber, the wiper holder comprising a positioning block extended from a first end thereof for engaging into the first locating member in the recessed bottom chamber to stop the wiper holder from rotary motion, a first round rod extended from the positioning block and pivoted to the first coupling groove in the recessed bottom chamber, and a second round rod extended from a second end thereof and pivoted to the second coupling groove in the recessed bottom chamber.
