[Technical field to which the invention belongs]

 The present invention relates to a cleaning brush for an automobile.

[0002]

[Prior art]

 Conventionally, with respect to an automotive cleaning brush in which a plurality of brush pieces are formed on an outer peripheral portion of a rotating shaft, for example, as described in Japanese Patent Application Laid-Open No. 2001-1870, a central portion of a cleaning body is synthesized over a predetermined length. There is disclosed a technique of forming by folding after coating with a resin. Also, in Utility Model Registration No. 3079414, a cleaning sheet in which mountain folds and valley folds are alternately repeated was attached to the rotary shaft with the mountain folds and the valley folds facing the center axis direction of the rotary shaft. Techniques have been disclosed.

[0003]

[Problems to be solved by the invention]

 However, in the case of Japanese Patent Application Laid-Open No. 2001-1870, since the cleaning body is coated with a synthetic resin, a coating process is required at the time of manufacturing the cleaning body, which complicates the manufacturing process and increases the manufacturing cost. Has the problem of becoming Another problem is that when the coating deteriorates, the desired effect cannot be obtained. In the case of Utility Model Registration No. 3079414, the cleaning sheet has a problem in that when rotating, the free end side of the sheet swells irregularly due to the number of rotations, making it difficult to achieve a predetermined cleaning effect. are doing.

[0004]

[Means to solve the problem]

 The present invention is configured as follows. (1) A cleaning brush for an automobile in which a plurality of brush pieces are formed on an outer peripheral portion of a rotating shaft, and a free end side of the brush piece is divided by a slit. And a bag-like body, and after the bag-like body is attached to the brush piece, the brush piece is attached to the rotating shaft.

[0005]

[Embodiment of the invention]

 First Embodiment FIGS. 1 to 4 show a configuration of a first embodiment. FIG. 1 is a front view of an automotive cleaning brush according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 denotes an automobile cleaning brush, 2 denotes a rotating shaft, 3 denotes a brush piece, 4 denotes a bag-like body, and 7 denotes a stopper. FIG. 2 is a perspective view showing a state in which the brush piece is mounted on the rotating shaft. In FIG. 2, 5 is a slit, and 6 is a circular hole. FIG. 3 is a perspective view showing the attachment of the bag-like body to the brush piece. FIG. 4 is a perspective view showing a bag-like body. In FIG. 4, reference numeral 41 denotes a notch, reference numeral 42 denotes a cylindrical portion, and reference numeral 43 denotes a retaining portion. As shown in FIG. 1, the cleaning brush for an automobile according to the present invention is formed by a rotating shaft 2, a brush piece 3, and a bag-like body 4. Grooves are formed on the outer circumference of the rotary shaft 2 at four equally spaced parts, and a stopper 7 for fixing the brush piece 3 folded in the center portion to the groove is detachably inserted and fixed. is there. A bag-like body 4 is formed below the brush piece 3 so as to wrap the brush piece 3 from the outside.

As shown in FIGS. 2 and 3, the brush piece 3 has two stoppers 7 at the folded central portion, and the bag-like body 4 is detachably fitted from the rotating shaft side of the brush piece 3. There is. A plurality of slits 5 are formed in the brush piece 3 from the free end side 8 toward the rotating shaft side, and a circular hole 6 is formed at the end on the rotating shaft side in communication with the slit 5. Have been. The length of the adjacent slits 5 is set so as to form a step every four rows.

As shown in FIG. 4, the bag-like body 4 is formed in a substantially T-shaped bag shape having two notches 41 at a lower portion. A retaining portion 43 is formed between the two notches 41, and a tubular portion 42 having a substantially square cross section is formed on the upper portion. The material is formed of cloth, felt, or the like having a predetermined strength according to the purpose. Since the bag-like body 4 has the above-mentioned shape, when the bag-like body 4 is mounted on the brush piece 3, the retaining portion 43 is sandwiched between the rotating shaft 2 and the brush piece 3 as shown in FIG. The portion 42 is prevented from falling off the brush piece 3.

Next, another example of the first embodiment will be described with reference to FIG. FIG. 5 is a perspective view of a brush piece 13 showing another embodiment of the first embodiment of the present invention. In FIG. 5, 13 is a brush piece, 4 is a bag-like body, 15 is a slit, 16 is a round hole, 17 is a stopper, and 18 is a free end side. The brush piece 13 of another embodiment is obtained by folding the cloth of the brush piece 13 so that the cross section thereof has a substantially W-shape, and then folding the center portion and fixing it with two stoppers 17. The bag-like body 4 is detachably fitted from the rotating shaft side of the brush piece 13. Further, the brush piece 13 has a plurality of slits 15 formed from the free end side 18 toward the rotation shaft side, and a circular hole 16 is formed at the end on the rotation shaft side in communication with the slit 15. It is. The length of the adjacent slits 15 is set so as to form a step every four rows.

In the present invention, the bag-like body is made of cloth, felt, or the like, but the material is appropriately set according to the purpose, such as using the same material as the brush piece. There is no problem at all. Also, the shape of the notch, the tubular portion, etc. of the bag-shaped body does not hinder even if it is set according to the purpose. Regarding the method of manufacturing the bag-shaped body, there is no problem whether the bag-shaped body is manufactured by a method such as sewing or an integrated method. Furthermore, although the bag-like body is detachably fitted to the brush piece, a method such as sewing and fixing the brush piece and the bag-like body in at least one place or more is implemented according to the purpose. However, there is no problem at all.

[0010]

[Effect of the invention]

 In the present invention, since the lower part of the brush piece is configured to be attached by a bag-shaped body, when the brush piece rotates, the lower part of the brush piece expands by a predetermined width and has a predetermined width. The above does not swell. Therefore, the brush piece can have a predetermined rigidity according to the purpose with respect to the surface to be cleaned, and as a result, it is possible to exert an appropriate and efficient cleaning action. In addition, by setting the shape of the cylindrical portion of the bag-like body, the degree of bulging of the brush piece can be adjusted arbitrarily. Further, since the bag is detachably attached to the brush piece, the bag can be easily and quickly replaced. Further, since the bag-like body is formed in a substantially T-shaped bag shape having two notches at the lower portion, the bag-like body does not fall off from the brush piece. In addition, when the cloth of the brush piece is folded so that the cross-section becomes approximately W-shaped, the center part is folded, and the lower part of the brush piece is In addition to being able to have a bulge to a predetermined width, the upper part of the brush piece has a substantially W-shaped cross section having a reaction force like a spring, so that a stronger cleaning action can be performed on the surface to be cleaned. Can be exerted.
