Description of the preferred embodiment Although specific forms of the invention have been selected for illustration in the drawings, and the following description is drawn in specific turns for the purpose of describing those forms of the invention, this description is not intended to limit the scope of the invention, which is defined in the claims.

Referring now to the drawings, and particularly to FIGURES 1 through 4, which show one embodiment of this invention relative to the brush for cleaning, it has a plurality of closely implanted short piles which are leaned to the surface thereof, as to the brush it will be hereinafter explained in detail.

In FIGURES 1 and 2, the brush for cleaning in accordance with the present invention comprises a brush surface 1, on which a plurality of short piles 2 made of fibers such as natural fibers, chemical fibers, synthetic fibers or glass fibers, threads or wools are provided closely thereon and the piles are leaned toward a constant direction, and a holding device including a handle 3 for a hand to be held and a holder 4 for supporting the brush surface 1 and means for turning the brush surface 1, which will be hereinafter described in detail. Proper length of the piles is 1-7 mm., and the inclined angle thereof is preferably 360, but may be 8().

Referring now to FIGURE 3, which shows a longitudinal view in section of the brush for cleaning relative to the present invention, the brush also comprises a resilient element 5 such as a helical spring in the embodiment, at base plate 6 for hearing the brush surface 1 at one side and on the other side provided at the periphery with a channel 7 for receiving and supporting the peripheral end 8 of the holder 4, a cylindrical hollow projection 9 projecting from the center portion of the base plate so as to receive and bearing the spring 5 on the inside top surface thereof, a hollow projection 10 projecting from the inside top surface of the holder 4 for supporting integrally a member 11 with a fastening means 12 such as a screw or pin, said member 11 adapted to receive and bear the other end of the resilient element or spring 5 which act so that it forces upwards in the drawing the 3 projection 9 integrally with the base plate 6 so as to fix the base plate 6 with the brush surface 1 through the channel 7 and end 8 facing and contacting each other to the holder 4.

In operation of turning the brush surface 1 at an angle of 180 degrees, when the handle 3 is held by the hand, and the peripheral edge of the base plate 6 is pulled away from the base plate the channel 7 of the base plate 6 separates from the end 8 of the holder 4, and both may be turned relative to each other. In this state, when the base plate 6 with the brush surface 1 is turned at angle 180 degrees, the direction of the leaned piles 2 on the brush surface 1 becomes inverse to the initial direction thereof or to the longitudinal direction of the handle 3, and in this state the channel 7 of the base plate 6 is adapted to receive the end 8 of the holder 4 so that both the holder 4 and the base plate 6 with the brush surface 1 may be fixed through the channel 7 and end 8 facing and contacting each other as the original state. The turning direction may be selectably either clockwise or counterclockwise.

In the event that the handle 3 is held by a right hand so as to brush the left portion of the suits, if the direction of the leaned piles 2 is downward, the left portion of the suits may be brushed by the brush surface 1 of the brush. When the handle 3 is held by a left hand just as the same state as aforementioned so as to brush the right portion of the suits, the brush surface 1 does not effect to remove the dust or cleaning function on the suits since the direction of the leaned piles 2 is upward and inverse to the brushing direction. In such a case, the brush in accordance with the present invention is provided to be turntable between the holder 4 or peripheral end 8 thereof and the channel '7 of the base plate 6 by pulling easily each other by hand to turn at an angle of 180 degrees so as to correspond the brushing direction to that of the leaned piles 2 integrally with the brush surface 1 to effect the cleaning function on the brush surface.

As previously described, the present invention provides the utility for enabling the direction of the base plate with the leaned piles 2 to immediately correspond to the brushing direction from either direction being provided especially when a certain surface is difiicult to brush except only one direction due to some reason. Furthermore, in order to turn the base plate 6 with the brush surface 1 according to the present invention, only the base plate 6 may be pulled from the holder 4 so as to separate the peripheral end 8 of the holder 4 from the channel 7 of the base plate 6, it being very easy and quick to do so by holding the peripheral end of the base plate by fingers. As shown in the embodiment in FIGURE 3, since the peripheral end of the base plate projects from the peripheral end of the holder 4, it is much easier to hold it by the fingers and to pull it so as to separate each other.

Referring now to FIGURE 5, which shows another embodiment of the present invention in the sectional form as means for holding the brush surface 1, it comprises as its feature a resilient element 5 such as plate spring as shown by the embodiment, a base plate 6 for supporting the brush surface 1 at one side, and on the other side provided at the periphery with a channel 7 for receiving and supporting the end 8 of the holder 4 similar to the previous embodiment, said spring 5 being secured at both ends to a suitable portion inside the holder 4 and also secured at its central portion to the center portion of the base plate 6 so as to pull each other to fix between the base plate 1 with the brush surface 1 and the holder 4 contacting each other through the channel 7 and end 8 facing each other, and a pin 12 for securing the center portion of the spring 5 and that of the base plate 6 so that the base plate 6 may be turntable to the spring or the holder by pulling the base plate from the holder so as 4 to separate the end 8 from the channel 7 of the base plate.

Referring now to FIGURES 6A and 6B, which show still another embodiment of the present invention, it comprises only a slot 13 on the base plate 6, and a projection 14 at the end of the holder 4 so that the projection 14 may be inserted to the slot 13 so as to secure each other, and this construction may effect to turn the base plate 6 from the holder by pulling out the plate and inserting it from the opposite end of the slot 13 to turn the brush surface at angle degrees.

In FIGURES 7A and 7B, which show still another embodiment of the present invention, it comprises merely a pivot connection 15 between the holder 4 and the base plate 6, and a slot 13 for receiving either side the handle 3 to be pivotally moved so as to substantially change the brush surface to the handle 3.

Referring now to FIGURES 8A and 8B, which show still another embodiment of the present invention, it comprises a pair of later-ally radially opposite projections 16 disposed on peripherally outside of the base plate 6, and a pair of receses 17 for receiving said projections so as to be resiliently inserted to fix the base plate 6 with the brush surface 1 to the holder 4, said base plate 6 being provided so as to be inserted to the holder 4 in opposite or inverse disposition in order to change the direction of the brush surface 1.
