Description

  The present invention relates to a cleaning brush, and more particularly to a cleaning brush used for cleaning a narrow portion such as a cleaning in a pipe bent into an S shape, a U shape or the like, or a floor surface below a bathtub.

In general, as a cleaning brush used to clean narrow areas that are out of reach, such as the inner surface of a bent pipe or the floor under a bathtub, a plurality of parallel long metal wires are twisted into one. A twist brush is used in which at least one end of a metal core member is provided with a rubbing portion composed of a large number of rubbing single fiber groups.
In this type of twisting brush, a plurality of metal wires set to a predetermined length are juxtaposed, and at least one end thereof, a number of single fiber groups are sandwiched so as to be orthogonal between the metal wires. By twisting up the metal wire, the single fiber group is finished in a radially extending manner from a single core made of a plurality of metal wires.
Since the metal core is bendable, the entire twisting brush can be deformed according to the shape of the rubbed portion. Accordingly, the core material can be inserted while being bent in variously bent pipes such as an S-shape and a U-shape, and the inside of the pipe can be rubbed and cleaned by the rubbing portion at the tip. It is also possible to clean the metal core by inserting it into a narrow space between the bathtub and the floor surface in a state where the metal core is straightened.

  However, since the metal core material constituting the conventional twisted brush does not have elasticity, the metal core material is easily bent, and once bent, it is difficult to return to the original state. If the core material is bent, there will be an inconvenience that the next use will be hindered and difficult to use repeatedly. In addition, if the core member has a bent wrinkle, there is a problem that the rubbing portion is lifted from the surface to be rubbed when rubbing a flat surface, and cleaning cannot be performed well.

  This invention is made | formed in view of the said situation, and makes it a subject to make the metal core material which comprises the brush for cleaning difficult to bend | curve, and to improve the workability | operativity of a cleaning operation | work.

(1) The cleaning brush of the invention according to claim 1 is a cleaning brush in which a rubbing portion in which a single fiber group for rubbing is implanted is formed on a bendable metal core material, A cableway that can be elastically deformed in the bending direction is externally fitted in the non-sliding portion formation region of the metal core material, and the elastic return force of the cableway tube is set to be larger than the bending holding force of the metal core material It is characterized by ".
The above means operates as follows.
The metal core material before use is linear, and the cableway pipe is externally fitted in a rubbing part non-formation area in which no rubbing part is formed. Since the cableway can be elastically deformed in the bending direction, the cableway is also elastically bent as the metal core is bent. Thereby, it can insert in a pipe bent in S shape, U shape, etc., making a metal core material and a cableway pipe bend, and the inside of the said pipe can be rubbed in a rubbing part. Thereafter, when the rubbing portion is extracted from the pipe, the bent portion of the metal core member is returned to the original straight state by the elastic restoring force of the cable duct.

(2) The cleaning brush according to the second aspect of the present invention is the cleaning brush according to the first aspect, wherein the cableway tube is formed into a long and thin tube by spirally winding a metal plate spring. When a force in the bending direction acts on the cableway, the cableway is bent while generating a gap between the leaf springs adjacent to each other outside the bent part. When the force in the bending direction is released, the cableway pipe returns to a straight line by the elastic return force of the metal leaf spring.

(3) The cleaning brush according to the third aspect of the present invention is the cleaning brush according to the first or second aspect, wherein “the resin layer is formed over the entire surface of the cableway” and the surface of the cableway Becomes an aspect covered with a resin layer. In particular, as in the second aspect of the present invention, when a cable leaf pipe in which a metal leaf spring is spirally wound is adopted, a resin layer is formed on the entire outer surface of the metal leaf spring. Even when a gap is formed between the leaf springs when the cableway is bent, the gap is not exposed to the outside.

(4) A cleaning brush according to a fourth aspect of the present invention is the cleaning brush according to any one of the first to third aspects, wherein both open ends of the cableway are blocked by a resin blocking member. In this case, water drops, dust, etc. do not enter inside from the open end of the cableway. In addition, what is necessary is just to make a metal core material protrude from a cable duct in the aspect which penetrates the said obstruction | occlusion member.

  As described above, according to the first aspect of the present invention, since the metal core material formed in a straight line and the cableway pipe fitted on the metal core material are freely bendable, the shape of a portion to be cleaned such as a pipe is obtained. Accordingly, the metal core and cableway can be bent and cleaned by rubbing at the rubbing portion. And if it pulls out from the said pipe, since a metal core material will be returned to linear form by the elastic return force of a cableway pipe, it will be hard to bend a wrinkle on a core material. Therefore, it is possible to eliminate the inconvenience that it is difficult to clean the next portion to be cleaned due to the bending rod attached to the core material, and it is possible to easily and surely fit the portion to be cleaned of different shapes. Workability is improved.

  Further, according to the invention according to claim 2, in addition to the above-mentioned effect, since a cable spring in which a leaf spring is wound spirally is adopted as the cable duct, the cable pipe can be reliably secured by the elastic return force of the leaf spring. Return to linear shape can be expected. In addition, since a gap is generated between the leaf springs outside the bent portion, the cableway pipe is not broken or broken at the bent portion.

  Furthermore, according to the invention which concerns on Claim 3, since the surface of a cableway pipe was covered with the resin layer, generation | occurrence | production of the rust of the whole cableway pipe | tube can be prevented.

  Further, according to the invention of claim 4, by closing both ends of the cableway with the closing member, the positioning of the cableway on the metal core is ensured, and the occurrence of rust inside the cableway It is possible to prevent adhesion of dirt.

Sectional drawing which shows the completion state of the brush for cleaning of embodiment of this invention. The principal part expanded fragmentary sectional view of the brush for cleaning of embodiment of this invention. The elements on larger scale which show the use condition of the brush for cleaning of an embodiment of the invention.

The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.
FIG. 1 is an explanatory diagram before a twisting process of a twisting brush employed in the cleaning brush according to the embodiment of the present invention, and FIG. 2 is a cross-sectional view of the completed cleaning brush according to the embodiment of the present invention. is there.

The twisting brush can be manufactured by the same process as the conventional one. First, as shown in FIG. 1, two long metal wires (11) are arranged in parallel by folding a long metal wire into two. A large number of single fiber groups (12) made of synthetic resin are sandwiched between the two metal wires (11) in an orthogonal state. In this state, both ends (11a) and (11b) of the metal wire (11) in a folded state are fixed to an instrument (not shown) and rotated from the closed end (11a) side so that two metal wires (11 ). As a result, as shown in FIG. 2, one metal core (1) is formed by the two metal wires (11) twisted together, and one end of the metal wire (11) is formed at one end thereof. The single fiber group (12) twisted into the shape is formed with a rubbing portion (2) projecting radially.
The metal core material (1) is bendable, but the cableway pipe (3) described later is placed outside the rubbing portion non-formation area (10) consisting only of the core material (1) other than the rubbing portion (2). The sliding part non-formation area (10) is linearly held by fitting.

As shown in FIG. 3, the cableway pipe (3) is formed in a long and thin tubular shape that can be externally fitted to the core material (1) by spirally winding a long strip-shaped leaf spring (31). Then, it is fitted on substantially the entire area of the non-rubbed area (10).
The surface of the cableway pipe (3) is covered with a stretchable resin layer (32), and at both open ends of the cableway pipe (3), a blocking member made of urethane two-component foamed resin ( 30) is packed. The core material (1) protrudes from both open ends in such a manner as to penetrate the closing member (30).

  The cable duct (3) is bendable as shown in FIG. 4, but the elastic return force of the leaf spring (31) in the bent state is the metal wire (11) constituting the core (1). Since it is set to be larger than the bending holding force, in a natural state, it is always maintained in a linear state as shown in FIGS.

In order to clean the inside of the U-shaped pipe (33) with the cleaning brush of the embodiment of the present invention, the vicinity of one end of the portion where the cableway pipe (3) is fitted is gripped by hand as a brush handle, Insert the rubbing part (2) into the pipe. As shown in FIG. 4, the metal core (1) is forcibly bent according to the bending of the pipe (33) together with the cableway pipe (3) as shown in FIG. The inside of (33) can also be cleaned by rubbing with the rubbing part (2). When the cleaning brush is removed from the pipe after rubbing, the cableway pipe (3) is returned to a straight line by the elastic return force of the leaf spring (31), and the core (1) is also straight without bending. To be restored.
As a result, after cleaning the pipe (33) bent in the U-shape, the pipes of other shapes can be easily cleaned in succession. Is held in a straight line, so there is no inconvenience that the rubbing part (2) is lifted from the surface to be cleaned by the curled surface of the core material (1) and is not easily rubbed. Cleaning is also easy.

In addition, since the resin layer (32) is formed on the surface of the cableway pipe (3), it is possible to prevent inconvenience that the cableway pipe (3) rusts, and it is adjacent when the cableway pipe (3) is bent. Since the gap (13) formed between the leaf springs (31) is also covered with the resin layer (32), water droplets and dirt do not enter the cable duct (3) from the gap (13).
Furthermore, since the open end of the cableway pipe (3) is filled with a foamed resin blocking member (30), the cableway pipe (3) may be moved inadvertently on the core material (1), or In addition to not falling off the material (1), water drops and dirt from the open end can also be prevented from entering the cableway (3).

In the above embodiment, the rubbing portion (2) is provided at one end of the metal core (1), but the rubbing portion (2) is provided at both ends of the metal core (1). The metal core material (1) positioned between the rubbing portions (2) and (2) may be used as the rubbing portion forming area (10) to externally fit the cableway pipe (3).
