[0001]

[Technical field to which the invention belongs]

 The present invention relates to a brush suitable for a rotating brush or the like of a car washing device.

[0002]

[Prior art]

 Since it takes a lot of effort and time to wash a dirty car, recently, electric rotating brushes were installed on the ceiling and side walls of the tunnel-like structure, and after the detergent was sprayed on the vehicle body, the tunnel-like structure was used. Car wash systems that can remove dirt simply by passing them through objects have come into use. As a rotating brush used in a car washing device, a lot of nylon hair is generally planted around a rotating shaft.However, if such a brush is used to wipe off all dirt, the vehicle body may be damaged. There is.

[0003] There is also known a cloth brush in which a number of cloth pieces are attached around a rotation shaft. The cloth brush makes soft contact with the car body, so it can quickly wipe off mud and dirt without damaging the car body.However, since the cloth pieces have poor durability, the entire brush must be replaced in a short time. Must. Furthermore, since the cloth pieces become very heavy when they contain water, not only does a large driving force be required to rotate the cloth brush, but also the maneuverability and stability are poor. There is a risk of deformation.

[0004]

[Problems to be solved by the invention]

 The purpose of the present invention is to be able to attach the necessary brush pieces according to the type of dirt or the type of object to be cleaned, to quickly and efficiently remove dirt, and to damage the object to be cleaned. It is an object of the present invention to provide a brush which is easy to replace worn brush pieces and has high durability.

[0005]

Means for Solving the Problems The brush of the present invention is composed of a tubular body having a large number of insertion grooves formed in the outer peripheral surface along the axial direction and having a narrower opening than the width of the back, and a cloth piece. A cloth brush piece which is alternately folded front and back along a plurality of parallel folding lines, folded in two at right angles to the folding line, and attached with a bar material along an edge of the folded half; A bristle brush piece obtained by bundling one end of a large number of elastic bristle bodies with a fixing member, and each of the insertion grooves of the tubular body is provided with either a bar member of a cloth brush piece or a fixing member of the bristle brush piece. Removably engage.

[0006] The structure including the cloth brush piece and the bristle brush piece reduces the weight of the whole brush when water is contained, and the bristle brush piece having elasticity promotes the standing of the cloth brush piece, and the tube body Prevents deformation of the brush, removes dirt that can be wiped lightly with a cloth brush piece, and rubs off stuck dirt with a bristle brush piece, increasing the efficiency of cleaning and preventing damage to objects to be cleaned due to excessive friction. A configuration in which either the bar of the cloth brush piece or the fixing member of the bristle brush piece is detachably engaged with each of the insertion grooves of the tube body makes it easy to replace the worn cloth brush piece and bristle brush piece. The ratio between the cloth brush piece and the bristle brush piece can be changed depending on the type of the object to be cleaned or the stain.

[0007]

[Embodiment of the invention]

 As shown in FIG. 1, the brush of the present invention includes a tubular body 1, a cloth brush piece 2, and a bristle brush piece 3. The tube 1 is integrally formed of a synthetic resin or the like, and has an annular cross section as shown in FIG. On the outer peripheral surface 11 of the tube body 1, a number of projecting pieces 12 are provided in the radial direction at appropriate intervals along the axial direction. At the tip of the overhanging piece 12, a bifurcated portion 121 is formed which is branched on both sides, and the section of each overhanging piece 12 has a Y-shape. Therefore, an insertion groove 13 is formed between the projecting pieces 12 on the outer peripheral surface 11 of the tubular body 1 along the axial direction and the width of the opening is smaller than the width of the back.

As shown in FIG. 3, the cloth brush piece 2 folds a soft cloth piece alternately front and back through a plurality of folding lines parallel to each other, and then folds the two in a direction perpendicular to the folding line. In addition, a bar 21 is attached along the end on the folded side. In order to mount the bar 21, the cloth piece is sewn near the folded end, and a cylindrical portion 20 is formed between the end and the sewn portion. Through. The diameter of the rod 21 is larger than the width of the opening of the insertion groove 13 of the tube 1 and slightly smaller than the width of the inner part.

As shown in FIG. 4, the bristle brush piece 3 is formed by bundling one end of a plurality of bristle bodies having elasticity with a fixing member 31. The fixing member 31 has a channel shape with a narrow opening, and securely holds one end of the hair inserted from the opening. Further, the cross-sectional outer shape of the fixing member 31 is formed slightly smaller than the cross-section of the insertion groove 13 of the tube 1.

In the brush of the present invention, one of the rod member 21 of the cloth brush piece 2 and the fixing member 31 of the bristle brush piece 3 is slid from one end into each of the insertion grooves 13 of the tube body 1. It is configured to be detachably engaged. At this time, since the width of the opening of the insertion groove 13 is smaller than the width of the back portion, there is no concern that the cloth brush piece 2 and the bristle brush piece 3 will escape from the insertion groove 13 even if a centrifugal force due to rotation is applied. . The ratio of arranging the cloth brush pieces 2 and the bristle brush pieces 3 can be appropriately changed according to the type of dirt and the type of the object to be cleaned. For example, in the example shown in FIG. 1, cloth brush pieces 2 and bristle brush pieces 3 are arranged alternately.

Further, when mud dirt that can be relatively easily wiped off or when the surface of the object to be cleaned is easily damaged, the cloth brush piece 2 is continuously engaged with the plurality of insertion grooves 13. After that, the bristle brush piece 3 can be engaged with one insertion groove 13 adjacent thereto. On the other hand, when dirt which must be scraped off by strong frictional force adheres or when the surface of the object to be washed is not easily damaged, the bristle brush pieces 3 are engaged with the plurality of insertion grooves 13 continuously, The cloth brush piece 2 may be engaged with one insertion groove 13 adjacent thereto.

When the brush is rotated for cleaning, the cloth brush piece 2 is curved as shown by the broken line in FIG. 5, but the cloth brush piece 2 is sandwiched by the bristle brush pieces 3 having elasticity. When the bristle brush piece 3 returns to the upright state after passing through the contact position with the object to be cleaned, the cloth brush piece 2 is also pushed by the bristle brush piece 3 and quickly stands up, so that the tube 1 is stabilized. Rotation suppresses the deformation. When the cloth brush piece 2 and the bristle brush piece 3 are worn and want to be replaced, or when the cloth brush piece 2 and the bristle brush piece 3 are to be replaced with each other, the bar 21 and the fixing member are fixed from the end of the insertion groove 13. By pulling out the member 31, the cloth brush piece 2 and the bristle brush piece 3 can be easily removed from the tube 1.

[0013]

[Effect of the invention]

 In the brush of the present invention, the cloth brush piece and the bristle brush piece are detachably attached to the tube, so when the cloth brush piece and the bristle brush piece are worn or soiled, only the part is easily replaced. The cloth brush pieces and bristle brush pieces can be arranged at an optimum ratio according to the type of dirt and the type of the object to be cleaned. Further, since the cloth brush piece and the bristle brush piece efficiently remove dirt suitable for each of them, the cleaning effect is improved, and there is no danger of rubbing the object to be cleaned and damaging its surface. Furthermore, it is lighter than the one with only the cloth brush piece attached when it contains water.However, when the curved cloth brush piece passes through the contact position with the object to be cleaned during rotation during use, the original The tube is pushed up by the bristle brush piece that returns to the upright state and rises up quickly, so that the tube rotates stably and does not have to be deformed, and as a result, the durability is greatly improved.
