The handle unit for the vacuum cleaner for controlling a cleaner body of the vacuum cleaner includes a handle body of the vacuum cleaner; and a supporting unit projected from one side of the handle body, the supporting unit holding an accessory brush, wherein the supporting unit and the handle body is molded in a single piece by the injection molding process. ## Claims ### Claim 1 A handle unit for a vacuum cleaner for controlling a cleaner body of the vacuum cleaner, the handle unit comprising: a handle body of the vacuum cleaner; and a supporting unit projecting from one side of the handle body, the supporting unit being adapted to hold an accessory brush, wherein the supporting unit and the handle body are molded in a single piece by the injection molding process, wherein the supporting unit comprises at least two supporting projections projected from a front surface of the handle body, and wherein the at least two supporting projections comprises first and second supporting projections projected in a lengthwise direction of the handle unit, and a third supporting projection projected in a widthwise direction of the handle unit, the first and second supporting projections connected with two catching projections of the accessory brush, and the third supporting projection pressing the accessory brush in a direction opposite to the handle body to bring the first and second supporting projections and the two catching projections in friction contact to one another and thereby locking the accessory brush to the handle unit. ### Claim 2 (depends on 1) The handle unit of claim 1, wherein the handle body is molded in a single piece by the injection molding process. ### Claim 3 (depends on 1) The handle unit of claim 1, wherein the accessory brush is locked or unlocked in the supporting unit without a separate fixing member. ### Claim 4 (depends on 3) The handle unit of claim 3, wherein the accessory brush is pushed down contacting the supporting unit so as to be locked in the supporting unit, wherein the accessory brush is pushed up so as to be separated from the supporting unit. ### Claim 5 A handle unit for a vacuum cleaner, comprising: a handle body; and a supporting unit integrally formed with and projecting from the handle body, the supporting unit having first and second supporting projections projecting in a lengthwise direction of the handle unit and a third supporting projection projecting in a widthwise direction of the handle unit, wherein the first and second supporting projections are configured to selectively connect with an accessory brush, and wherein the third supporting projection projects further from the handle body than the first and second supporting projections so that the third supporting projection can push the accessory brush in a direction opposite to the handle body to bring the first and second supporting projections and the accessory brush in friction contact to one another so as to lock the accessory brush to the handle body without a separate fixing member. ### Claim 6 (depends on 5) The handle unit of claim 5, wherein the supporting unit is configured such that the accessory brush can be locked to the handle body by pushing the accessory brush downward and such that the accessory brush can be unlocked from the handle body by pushing the accessory brush upward. ### Claim 7 (depends on 5) The handle unit of claim 5, wherein the first and second supporting projections are substantially parallel with each other. ### Claim 8 (depends on 5) The handle unit of claim 5, wherein the first and second supporting projections project from the handle body to substantially the same height. ### Claim 9 (depends on 5) The handle unit of claim 5, wherein the third supporting projection is disposed at an approximate center between top ends of the first and second supporting projections and is disposed substantially perpendicular to the first and second supporting projections. ### Claim 10 (depends on 5) The handle unit of claim 5, wherein the first and second supporting projections are formed in a substantially straight duct shape having an inner space with one opened face and three closed faces. ### Claim 11 (depends on 5) The handle unit of claim 5, further comprising a connecting plate connecting the first, second, and third supporting projections. ### Claim 12 (depends on 11) The handle unit of claim 11, wherein the first and second supporting projections each comprise a first guiding plate, a second guiding plate, and a third guiding plate, wherein the first guiding plate depends from the front surface of the handle body, the second guiding plate is spaced apart from the first guiding plate and parallel to the first guiding plate, the third guiding plate is disposed between side ends of the first and second guiding plates so that the third guiding plate connects the first and second guiding plates, and wherein the third guiding plate is connected to the connecting plate. ### Claim 13 A vacuum cleaner comprising: an accessory brush having first and second catching projections projecting from a bottom surface parallel with and symmetrical to each other; a handle body; and a supporting unit integrally formed with and projecting from the handle body the supporting unit selectively securing the accessory brush to the handle body, the supporting unit having first and second supporting projections projecting in a lengthwise direction of the handle unit and substantially parallel with each other and a third supporting projection projecting in a widthwise direction of the handle unit, wherein the first and second supporting projections are configured to selectively connect with the first and second catching projections of the accessory brush, respectively, and wherein the third supporting projection projects further from the handle body than the first and second supporting projections so that the third supporting projection can push the accessory brush in a direction opposite to the handle body to bring the first and second supporting projections and the first and second catching projections in friction contact to one another so as to lock the accessory brush to the handle body without a separate fixing member. ### Claim 14 (depends on 13) The vacuum cleaner of claim 13, wherein the supporting unit is configured such that the accessory brush can be locked to the handle body by pushing the accessory brush downward and such that the accessory brush can be unlocked from the handle body by pushing the accessory brush upward. ### Claim 15 (depends on 13) The vacuum cleaner of claim 13, wherein the first and second supporting projections project from the handle body to substantially the same height. ### Claim 16 (depends on 13) The vacuum cleaner of claim 13, wherein the first and second supporting projections are formed in a substantially straight duct shape having an inner space with one opened face and three closed faces. ### Claim 17 (depends on 13) The handle unit of claim 13, further comprising a connecting plate connecting the first, second, and third supporting projections. ### Claim 18 (depends on 17) The handle unit of claim 17, wherein the first and second supporting projections each comprise a first guiding plate, a second guiding plate, and a third guiding plate, wherein the first guiding plate depends from the front surface of the handle body, the second guiding plate is spaced apart from the first guiding plate and parallel to the first guiding plate, the third guiding plate is disposed between side ends of the first and second guiding plates so that the third guiding plate connects the first and second guiding plates, and wherein the third guiding plate is connected to the connecting plate.
