Description

  The present invention relates to a cleaning brush, and more particularly to a cleaning brush suitable for use in cleaning curved surfaces and narrow places.

  2. Description of the Related Art Conventionally, as a cleaning brush for a toilet bowl or the like, a structure in which a cleaning member such as a sponge or brush hair is provided on a hard base fixed to a long handle tip is known (see Patent Document 1).

However, since these cleaning brushes lack flexibility, it is good to clean dirt adhering to the flat part in the toilet bowl, but the cleaning surface 30a of the cleaning brush 30 is placed in the toilet bowl 40 as shown in FIG. (In this case, it is difficult for the operator to change the angle with the brush each time according to the curved surface to be cleaned). In particular, as shown in FIG. 7B, when cleaning a narrow and angled part such as the bottom 40a close to the drainage port of the toilet 40, the angle of the handle cannot be changed extremely because the narrow part interferes. It was difficult to reliably scrape the dirt on the narrow back side.
Therefore, it takes a lot of time and labor to remove the dirt adhering to the cleaning object with many curved surfaces such as the inside of the toilet bowl with the cleaning brush 30 having the above structure, which is a very troublesome work.
In addition, although not shown in the figure, the cleaning brush that swings the base of the handle used for bath washing etc. will not be able to determine the point of the handle because it will bend too much when applying force, so it is difficult to wash with force. Not suitable for cleaning curved surfaces.
Japanese Patent Laid-Open No. 8-140892

  The present invention has been made in view of the above problems, and an object of the present invention is to provide an easy-to-use cleaning brush that can reliably clean curved surfaces and narrow and angled portions.

That is, the invention according to claim 1 is a brush portion formed by connecting a plurality of bases made of a rectangular body having at least three brush surfaces provided with a cleaning member in a thin-walled bridge portion, respectively. In the cleaning brush composed of the handle portion that holds the brush portion, the brush portion is connected to the base and the bridge portion at a position near the head that does not have the brush surface, The bases are connected to each other at intervals that allow the heads of the adjacent bases to come into contact with each other and bend to the head side at a certain angle or less, and the adjacent bases face each other. A portion close to the brush surface, which is arranged in parallel with the head side surface provided with the bridge portion of at least one surface of the connection surface, abuts on the connection surface facing to the brush surface side. this provided with a protruding portion for regulating the bend It is characterized in.

According to a second aspect of the present invention, in the cleaning brush according to the first aspect, the base and the bridge portion are integrally formed.

According to a third aspect of the present invention, in the cleaning brush according to the first or second aspect , the reinforcement is made of an elastic plate material embedded so as to penetrate at least the bridge portion in the connecting direction of the base. It is characterized by comprising a member.

According to a fourth aspect of the present invention, in the cleaning brush according to any one of the first to third aspects, the cleaning member is a hair, a sponge, or a non-woven fabric.

According to the present invention, since a large number of bases each having a cleaning member on the surface are configured to be flexibly connected to each other by a thin bridge portion, the brush surface formed by the cleaning member can be bent freely. Various curved surfaces and narrow and angled parts can be cleaned smoothly. In addition, the bending of the brush surface is always regulated to a certain angle or less when the corners of the heads of the bases come into contact with each other, so that the cleaning portion can be firmly rubbed with force.
In addition, since the bases are connected to each other at positions close to the head by the bridge portion, the warpage of the brush surface can be increased, and even if it is a large curved surface, the brush surface can be attached and reliably Can be cleaned.
Further, since the warpage to the inner side of the brush surface is regulated by the protruding portion, it is possible to scrub the toilet back and the like with force on the upper surface of the brush tip with the brush surface facing downward.
Further, by embedding a reinforcing member in the bridge portion, durability of the bridge portion when the brush surface is bent can be improved.

  Hereinafter, an embodiment of a cleaning brush according to the present invention will be described based on the drawings.

  As shown in FIGS. 1 and 2, the cleaning brush according to the present embodiment includes a long handle 20 and a brush portion 10 that is fixed and held at the tip of the long handle 20.

The brush part 10 includes a base 1 in which bundled brush hairs 2 are evenly planted on each surface (back surface and both side surfaces) excluding the head 1a in parallel with each other at a thin bridge portion 3, and It is formed by connecting a large number of flexibly.
The base 1 is formed of a rigid plastic square, and a bridge portion 3 is integrally formed as shown in FIG. The bridge portion 3 is formed to be extremely thin compared to the thickness of the base 1, and the bridge portion 3 is formed so as to connect the bases 1 at positions close to the head 1 a. The base 1 on the tip side of the brush portion 10 has a circular tip at the tip of the brush surface 10a so that the tip protrudes somewhat upward.

Further, a projecting portion 5 is formed on the opposing surface 1b (connecting surface 1b) of each adjacent base 1 and in the substantially center in the width direction near the brush surface 10a from the bridge portion 3. The protruding portion 5 is configured so that the tip end portion thereof is substantially in contact with the facing surface 1b in a normal state where the brush is not bent.
In the present embodiment, the protruding portion 5 is provided only on one side of the opposing connecting surfaces 1b and 1b. However, the protruding portions 5 are provided on both connecting surfaces 1b and 1b at different positions so that they do not contact each other. Alternatively, it may be provided, or the entire thickness of the connecting surface 1b closer to the brush surface 10a than the bridge portion 3 may be thickened.

  In the above configuration, when the brush part 10 is pressed by holding the long handle 20, the elasticity of the bridge part 3 causes the brush part 10 to bend freely as shown in FIGS. 3 and 4, and the brush surface 10a is changed according to the pressing force. Curve arbitrarily.

Accordingly, as shown in FIG. 6A, the brush surface 10a can be attached to various curved surfaces in the toilet 4 and smoothly cleaned while the long handle 20 is gripped at an easy-to-clean angle. As described above, since the tip of the brush surface 10a is circular, cleaning is made smoother. Further, as the brush portion 10 is bent, the heads 1a of the bases 1 come into contact with each other at the corners, and the brush surface 10a is always regulated to a certain angle or less. Can be washed.
In addition, as described above, the bridge portion 3 is formed at a position near the head 1a of the base 1, so that the warp of the brush surface 10a can be increased, and the brush surface can be applied to a large curved surface in the toilet bowl. 10a can be reliably added. For example, as shown in FIG. 6B, the narrow and largely curved portion of the bottom 4a near the drain of the toilet 4 can be reliably cleaned to the back side.
Further, the edge of the toilet bowl is scrubbed using the upper surface of the brush tip with the brush surface 10a facing downward, but the protrusion 5 mentioned above abuts on the connecting surface 1b by bending at that time, Since the bending is restricted, the brush surface 10a does not warp further inward, so that force can be applied to clean the brush surface 10a.

  As described above, in this embodiment, the brush hair is used as the cleaning member of the brush unit 10, but a sponge, a nonwoven fabric, or the like may be used.

Further, as another embodiment, as shown in FIGS. 5A and 5B, a structure in which each thin bridge portion 3 is reinforced by a reinforcing member 8 can be used.
The reinforcing member 8 is composed of an elongated elastic plate material embedded in the brush portion 10 by, for example, insert molding so as to penetrate each bridge portion, and to improve the fixing property of the reinforcing member 8 The trapezoidal rising portions 8a are provided on both end sides. As the reinforcing member 8, a synthetic resin plate (for example, a thin plate made of polypropylene) excellent in rigidity, bending strength, or the like, or a thin elastic metal plate can be used.
Thus, by embedding the reinforcing member 8 in the brush portion 10 and reinforcing the bridge portion 3, it is possible to prevent the bridge portion 3 from being bent due to the bending operation of the brush portion 10, and greatly improve the durability of the brush portion 10. be able to.

  Moreover, although cleaning of the toilet bowl was demonstrated in this embodiment, the cleaning brush of this invention is used for cleaning of a washbasin, a sink, a bathroom etc. in addition to cleaning of such a toilet bowl. The part can be cleaned smoothly.
