JP 2002-316622 A Utility model registration No. 3089760

  A conventional brush piece of a washing brush for a car washing machine, a washing brush provided with the brush piece, and a car washing machine equipped with the washing brush have been disclosed, for example, as a technique having the characteristics as described above. In the technology disclosed in 2002-316622, the surface of the sheet-shaped cleaning body has innumerable small irregularities made of innumerable closed cells, but the irregularities are produced when a synthetic resin foam is produced. Since it is inevitably formed and the outer diameter is generally a fine one of about 30 to 150 μm, the surface of the sheet-like cleaning body is close to a smooth surface rather than a rough surface. Therefore, the brush hairs that are subdivided and formed by a plurality of slits at the free end of the sheet-like cleaning body, when the cleaning brush rotates during the car wash, the adjacent brush hairs ride on each other's smooth surface and are cleaned. When contacted with water, etc., it easily sticks with washing water retained in the countless closed-cell recesses or with cleaning water adhering to the surface of smooth brush hair. The impact force on the surface to be cleaned of the bristles due to rotation could not be separated and separated from each other. For this reason, since a plurality of brush hairs that are attached to each other are integrated, a portion of the cleaning brush where the brush hair does not contact the surface to be cleaned is generated, and the brush hair may uniformly contact the surface to be cleaned. Since it was not possible, there was a problem that unwashed residue was generated and the cleaning performance was inferior.

  Adjacent brush hairs are attached to each other with washing water, etc., so that the brush hairs freeze in winter, especially in cold regions, and the frozen brush hairs adhere to the surface to be cleaned and cause car wash damage. There was also a problem.

  Further, in the technique disclosed in Utility Model Registration No. 3809760, a plurality of hollow crushing marks are formed in the vicinity of the inner end portion and the side edge portion of the tip split slit. The effect of the residual strain is exhibited, and it is possible to open the adjacent tip pieces in a V shape and separate them from each other. However, since the surface of the tip piece is formed as a flat smooth surface, when adjacent to each other such that adjacent V-shaped tip pieces are stacked, they are stuck to each other by washing water or the like. As a result, a plurality of generally V-shaped tip pieces are integrated, scraping performance of dirt adhering to the surface to be cleaned is inferior, and cleaning performance deteriorates.

  The present invention solves the above-mentioned conventional problems, and the divided pieces formed by the slits do not stick to the washing water over a long period of time, have a high washing performance with no generation of washing residue, and freezing. It is an object of the present invention to provide a brush piece of a washing brush for a car wash machine to be prevented, a washing brush for a car wash machine provided with the brush piece, and a car wash machine equipped with the washing brush for the car wash machine.

  In order to solve the above-mentioned conventional problems, the brush piece of the washing brush for a car wash machine according to the present invention is for a car wash machine used for a car wash machine for washing dirt or the like adhering to a surface to be cleaned of an automobile or a vehicle. In the brush piece of the cleaning brush, the brush piece has a flat plate-shaped synthetic resin foam, and the synthetic resin foam has divided pieces formed by slits, and at least one or more in the slit forming region. Are formed on the surface of the divided pieces even if adjacent divided pieces or adjacent divided pieces overlap each other during a car wash. Since the portion is formed, the contact area is small and it is difficult to make close contact as compared with the case where the divided pieces made of smooth surfaces overlap each other. Accordingly, the overlapping divided pieces can be easily separated and separated from each other only by the impact force at the time of contacting the brush piece with the surface to be cleaned. Is prevented. For this reason, the divided pieces are brought into contact with the surface to be cleaned without being integrated, so that generation of unwashed parts is suppressed and high cleaning performance is achieved.

  In addition, the recessed part and / or convex part currently formed in the brush piece of this invention are not the unevenness | corrugation by the bubble necessarily formed when manufacturing a synthetic resin foam, but after manufacture of a synthetic resin foam. The synthetic resin foam is a concave portion or a convex portion formed by, for example, applying heat such as heat pressing using an embossing roll or the like. Moreover, the form which melt-deforms the surface of a synthetic resin foam and forms a recessed part or / and a convex part is also employable.

  Further, the adjacent divided pieces are stuck with washing water or the like and are not integrated, so that the brush pieces are prevented from freezing.

  In addition, the slit having an inclination angle with respect to the side edge portion of the synthetic resin foam moves the divided piece obliquely by the inclination angle when the brush piece contacts the surface to be cleaned. Therefore, the slit does not have the inclination angle. Compared to, the sticking of the divided pieces is further suppressed.

  Moreover, the washing brush for car wash machines of this invention has a brush piece of the shaft body and the washing brush for car wash machines of any one of Claim 1 to 3, and the said brush piece in the outer peripheral part of the said shaft body Since the adjacent divided pieces do not stick to each other with cleaning water or the like, there is no unwashed and high cleaning performance.

  Further, the car wash machine of the present invention comprises a drive source, a nozzle for spraying cleaning agent and cleaning water sprayed on the surface to be cleaned, and a drying means for drying the surface to be cleaned after cleaning. The car wash machine is equipped with a washing brush for car wash machines and has a high washing performance with no washing residue, so the car wash machine slows down the rotation of the wash brush for the car wash machine by the drive source. Even when the cleaning time is set to a short time, excellent cleaning performance is exhibited. Moreover, since the freezing of the brush piece is prevented, the car wash damage caused by the brush piece does not adhere to the surface to be cleaned.

  In the invention of claim 1, the brush piece can have high cleaning performance and excellent anti-freezing performance.

  In the invention of claim 2, since the dirt that adheres firmly to the surface to be cleaned can be scraped off by the recessed portions formed over the entire area of the divided pieces or / and the edge portions of the protruding portions, the cleaning performance Is greatly improved.

  In the invention of claim 3, the divided piece is not on the surface to be cleaned even when the adjacent divided pieces overlap each other as compared with the case where the slit is formed at a substantially right angle with respect to the side edge portion of the synthetic resin foam. Since the contact is made while drawing a slanted cleaning locus, it becomes easier to leave, and the occurrence of streaks is prevented, and the cleaning performance is dramatically improved.

  In invention of Claim 4, the washing brush for car wash machines which has the high washing | cleaning performance with no unwashed residue can be provided.

  According to the fifth aspect of the present invention, it is possible to provide a car wash machine having excellent cleaning performance without causing scratches due to the brush pieces to adhere to the surface to be cleaned.

  1st invention is a brush piece of the washing brush for car wash machines used for a car wash machine for washing dirt etc. which adhered to the to-be-washed surface of a car or a vehicle, and the brush piece is flat synthetic resin foam The synthetic resin foam has divided pieces formed by slits, and at least one or more concave portions or / and convex portions are formed in the slit forming region, and are adjacent to each other. Even if the divided pieces or adjacent divided pieces that overlap each other are overlapped during the car wash, a concave or / and convex portion is formed on the surface of the divided pieces, so that the divided pieces made of smooth surfaces overlap. Compared with, the contact area is small and it is difficult to adhere. Accordingly, the overlapping divided pieces can be easily separated and separated from each other only by the impact force at the time of contacting the brush piece with the surface to be cleaned. Is prevented. For this reason, since the divided pieces are brought into contact with the surface to be cleaned without being integrated, occurrence of unwashed portions is suppressed and high cleaning performance can be achieved.

  In addition, since the adjacent divided pieces are attached by washing water or the like and are not integrated, the brush pieces can be prevented from freezing.

  In the second invention, in particular, in the brush piece of the washing brush for a car wash machine according to the first invention, the concave portion or / and the convex portion are formed at least over the entire area in the slit forming region. When the divided pieces come into contact with the surface to be cleaned, the dirt firmly adhered to the surface to be cleaned is scraped by the edge portions of the concave portions and / or convex portions formed over the entire area of the divided pieces. Therefore, the cleaning performance is greatly improved.

  According to a third aspect of the invention, in particular, in the brush piece of the washing brush for a car wash machine according to the first to second aspects, the slit is formed with an inclination angle with respect to a side edge of the synthetic resin foam. Thus, compared to the case where the slit is formed at a substantially right angle with respect to the side edge portion of the synthetic resin foam, the divided piece has a cleaning locus inclined with respect to the surface to be cleaned even when the adjacent divided pieces overlap. Since it abuts while drawing, it becomes easier to separate, and the occurrence of streaky washing residue is prevented. Therefore, the cleaning performance is greatly improved.

  4th invention has a brush piece of the washing brush for car wash machines given in any 1 paragraph of the shaft body and the 1st-3rd invention, and the brush piece is formed in the perimeter part of the shaft body. Since a car brush washing brush is used, adjacent divided pieces do not stick to each other with washing water or the like, and therefore the car wash washing brush can have a high washing performance with no washing residue.

  The fifth invention comprises a drive source, a nozzle for spraying cleaning agent and cleaning water sprayed on the surface to be cleaned, and a drying means for drying the surface to be cleaned after cleaning, and for the car wash machine of the fourth invention. It is a car wash machine equipped with a washing brush, and because it has a washing brush for car wash machines that has high washing performance with no residue left behind, the car wash machine rotates the washing brush for car wash machines at a low speed by the drive source. Even when the cleaning time is set to a short time, excellent cleaning performance is exhibited. Moreover, since the freezing of the brush piece is prevented, the car wash damage caused by the brush piece does not adhere to the surface to be cleaned.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Example 1)
1A is a perspective view of a washing brush for a car wash machine according to the present invention as viewed from the front side, FIG. 1B is a sectional view of FIG. 1A, and FIG. 2 is a first view of the present invention. It is a partial top view of the brush piece in an Example.

  1 (a) and 1 (b), a washing brush 9 for a car wash machine has brush pieces 1 provided at four locations on the outer periphery of a substantially cylindrical shaft body 10 made of a metal material such as aluminum. It is inserted into the groove portion 19 so as to have a substantially V-shaped cross section, and is fixed by a rivet 20. The brush piece 1 is made of a synthetic resin foam 2 and has a plurality of divided pieces 4 subdivided by slits 3 provided in a step shape on the cleaning side, and the brush piece 1 on the side in contact with the surface to be cleaned of the divided pieces 4 Convex portions 6 are formed on the surface, and concave portions 5 that are inevitably formed by forming the convex portions 6 are formed. The surface of the synthetic resin foam on the side where the concave portion 5 and the convex portion 6 are not formed is a smooth surface. A circular hole 7 is provided at the end of the slit 3 on the shaft body 10 side. In addition, the groove part 19 provided in the outer peripheral surface of the shaft body 10 can be set in a timely manner according to the purpose of use, such as 6 places, 8 places, and 12 places, in addition to the four equally divided places.

  The washing brush 9 for a car wash machine is manufactured by the following procedure. First, a brush piece 1 made of a flat synthetic resin foam 2 in which a slit 3, a circular hole 7, and a mounting hole (not shown) are formed in a substantially central portion in the longitudinal direction is prepared in advance by a Thomson type or the like. Next, the brush piece 1 is folded in half at a substantially central portion in the longitudinal direction so as to have a substantially V-shaped cross section. The brush piece 1 formed so as to have a substantially V-shaped cross section is inserted into the groove portion 19 of the shaft body 10, and the rivet 20 is inserted into the mounting hole, and the rivet 20 is hit with a riveter or the like. The piece 1 is fixed and the washing brush 9 for a car wash machine is manufactured.

  Next, the brush piece 1 will be described in detail with reference to FIG.

  In FIG. 2, the brush piece 1 is made of a flat synthetic resin foam 2, and is formed with a divided piece 4 that is subdivided by a slit 3 provided in a step shape, and a surface on one side of the divided piece 4. A concave portion 5 and a convex portion 6 are formed. The concave portion 5 and the convex portion 6 are formed within the range of the slit forming region 8 of the slit 3. The thickness of the synthetic resin foam 2 is set to about 1 to 5 mm, the length of the slit 3 is set to about 20 to 200 mm, and the width of the divided piece 4 is set to about 1 to 10 mm. When the thickness of the synthetic resin foam 2 is less than 1 mm, the brush piece 1 is likely to be frayed due to wear and has poor durability, and when it exceeds 5 mm, the cleaning sound increases. In addition, when the length of the slit 3 is less than 20 mm, the divided pieces 4 are less likely to come into contact with the fine uneven portions of the surface to be cleaned, and the cleaning performance is inferior. It becomes easy to get entangled with equipment such as a wiper, etc., leading to damage to the equipment. In addition, when the width of the divided piece 4 is less than 1 mm, the divided piece 4 is likely to be cut and the durability is inferior. When the divided piece 4 exceeds 10 mm, the divided piece 4 removes dirt adhering to the fine uneven portions of the surface to be cleaned. The cleaning performance is poor. The circular hole 7 formed at one end of the slit 3 is provided to prevent the brush piece 1 from tearing.

  Next, the manufacturing method of the brush piece 1 is demonstrated.

  First, a pellet or powdery synthetic resin is inserted into a rectangular parallelepiped mold, and additives such as a foaming agent and a crosslinking agent are mixed and heated to foam the synthetic resin, and the synthetic resin. A covalent cross-linking structure is naturally formed between the molecules. A foam in which a covalent cross-linked structure is formed between molecules of a synthetic resin is generally called a cross-linked foam, and since a bridge structure is formed between the molecules, it has excellent elasticity. . Next, the obtained cubic foam is sliced to a desired thickness to form a flat synthetic resin foam 2.

  Next, the concave portion 5 and the convex portion 6 are formed on one surface of the synthetic resin foam 2 by pressurization and heat pressurization using an embossing roll or the like. In the present embodiment, the concave portion 5 and the convex portion 6 are formed only on one surface of the synthetic resin foam 2, but the embodiment in which the concave portion 5 and the convex portion 6 are formed on both surfaces of the synthetic resin foam 2 is adopted. May be. In addition, the shape of the recessed part 5 and the convex part 6 is not specifically limited, Like the present Example, besides the form in which the cross-sectional shape of the convex part 6 is formed in the substantially square shape, As long as sticking by washing water or the like is prevented, a round shape, a triangle shape, a pentagon shape, a rhombus shape, a saddle shape, or the like may be used. Further, the depth of the concave portion 5 or the height of the convex portion 6 is not particularly limited as long as it prevents sticking of the divided pieces 4 with washing water or the like and generation of unwashed residue, For example, if the height of the convex portion 6 is 0.1 mm or more and is set within about ½ of the thickness of the synthetic resin foam 2 to be used, sticking of the divided pieces 4 due to washing water or the like is suppressed. In addition, the divided pieces 4 are preferable because they are easy to adhere to the surface to be cleaned and the occurrence of unwashed parts is prevented. In addition to the embossing roll and the like, for example, abrasive paper, polishing cloth or the like can be rubbed against the surface of the synthetic resin foam 2 to form fine concave portions 5 and convex portions 6.

  Next, using a Thomson mold or the like, the slit 3, the circular hole 7, and the attachment hole (not shown) are formed in the synthetic resin foam 2 with a cutting blade, and the brush piece 1 is manufactured. The recesses 5 and the protrusions 6 are formed in the slit forming region 8. Moreover, after providing the slit 3, the circular hole 7, and the attachment hole (not shown) in the synthetic resin foam 2, the recessed part 5 and the convex part 6 are formed using an embossing roll, abrasive paper, polishing cloth, etc. There is no problem.

  The foaming ratio of the synthetic resin foam 2 is adjusted from 2 to 15 times from the viewpoint that it has flexibility and gives the brush pieces 1 fluff and does not attach scratches to the surface to be cleaned. Is preferred. When the expansion ratio is less than 2 times, it is too hard and the flexibility is impaired, and it becomes easy to attach scratches to the surface to be cleaned. It is difficult to apply and the cleaning performance is inferior. In order to combine more excellent flexibility and hairiness, it is desirable to adjust the expansion ratio by 5 to 12 times.

  Although not particularly illustrated, innumerable fine closed cells are formed on the surface of the synthetic resin foam 2, and the synthetic resin foam 2 as described above is generally called a closed cell foam. ing. A closed bubble is a bubble whose wall surface is completely surrounded. Therefore, since adjacent bubbles are separated by the wall surfaces of the bubbles and exist independently, liquid such as washing water does not circulate in the bubbles. Therefore, the brush piece 1 only stores the washing water temporarily in the closed cells on the surface of the synthetic resin foam 2 during the car wash, and the car wash machine washing brush 9 suppresses the water content of the brush piece 1 as much as possible. Therefore, the load on the rotational drive source is reduced, and the washing brush 9 for the car wash machine can maintain a stable rotation for a long period of time.

  Examples of the synthetic resin used when producing the synthetic resin foam 2 include ethylene vinyl acetate, ethylene methyl acrylate, ethylene ethyl acrylate, ethylene butyl acrylate, ultra-low density polyethylene, low density polyethylene, linear low density polyethylene, Polyolefin resins such as medium density polyethylene, high density polyethylene, polypropylene, and polystyrene are preferably used. In addition to polyolefin resin, polyamide resin, polyester resin, polyurethane resin, acrylic resin, fluorine resin, silicone resin, polyvinyl chloride resin, polyvinyl alcohol resin, polycarbonate resin, polyacetal resin, methacrylic resin, phenol resin, urea resin An alkyd resin, a melamine resin, an epoxy resin, or the like may be used. The synthetic resins can be used alone or in combination.

  Moreover, as said foaming agent used when manufacturing the synthetic resin foam 2, if it is conventionally used for manufacture of the synthetic resin foam 2, it will not specifically limit, For example, sodium bicarbonate, Pyrolytic foaming agents such as ammonium bicarbonate, azodicarbonamide, benzenesulfonylhydrazide, dinitrosopentamethylenetetramine, toluenesulfonylhydrazide, 4,4-oxybisbenzenesulfonylhydrazide are preferably used, and the above materials are used alone. Or may be used in combination.

  Moreover, as said crosslinking agent used when manufacturing the synthetic resin foam 2, if it is conventionally used for manufacture for the purpose of providing elasticity to the synthetic resin foam 2, it will not specifically limit. For example, organic peroxides such as dicumyl peroxide, 2,5-dimethyl-2,5-bis-tertiarybutyl peroxyhexene, 1,3-bis-tertiary peroxyisopropylbenzene are preferably used, The materials may be used alone or in combination.

  Next, the cleaning performance of the brush piece of the washing brush for a car wash machine of the present invention and the sticking of the divided pieces with the washing water were tested. Table 1 shows the composition of the test piece used in the test. The measurement was performed as shown below, and the results are shown in Table 2. Note that, as a comparative example, a test piece having the same composition of the synthetic resin foam as that of the example and having no concave portions and convex portions formed on both surfaces was used.

  Four strip-shaped test pieces made of a synthetic resin foam having a number of closed cells on the surface and a rectangular cross section of 50 mm in width, 2.5 mm in thickness, and 226 mm in length were cut out. Further, nine slits having a length of 50 mm were formed on the cleaning side of the strip-shaped test piece, and a circular hole having an outer diameter of 2 mm was provided at one end portion, thereby forming ten pieces having a width of 5 mm. In addition, in the test piece of an Example, the convex part of length 2mm * width 1mm * height 0.9mm was formed in the slit formation area | region by heat-pressing with the embossing roll.

  Then, each test piece is folded in half from the central portion in the length direction on the outer peripheral surface of a cylindrical rotating body having a diameter of 114 mm and a length of 360 mm, and the width direction rotates. Four test pieces were attached at equal intervals in the circumferential direction of the rotating body, with the outer surface of the bending portion of the test piece being in contact with the outer peripheral surface of the rotating body, matching the length direction of the body.

  Next, while rotating the rotating body at a constant rotational speed of 240 rpm, a white solid coated steel sheet coated with artificial dirt on one surface was prepared, and each rotating body was attached to the outer peripheral surface of the rotating body rotating at the rotational speed. The white solid-coated steel sheet is disposed at a position close to the rotation axis direction of the rotating body by 30 mm from the virtual circle drawn by the tip of the test piece, with its dirt surface facing the rotating body, and 6 L per minute. The test piece was sequentially brought into sliding contact with the dirty surface of the steel plate for 1 minute while spraying the cleaning water at the spraying amount to remove the stain on the steel plate. In addition, in the test piece of an Example, the surface in which the recessed part and the convex part were formed in the surface was made to contact | abut to the steel plate.

And the brightness of the part which removed the stain | pollution | contamination with the test piece in the stain | pollution | contamination surface of a steel plate was measured with the color difference meter NR-1 by Nippon Denshoku Industries Co., Ltd., and the following reference | standard judged.
○ ・ ・ ・ Brightness improvement is +5 or more △ ・ ・ ・ Brightness improvement is +2 or more and less than +5 × ・ ・ ・ Brightness improvement is less than +2

Moreover, the sticking by the wash water of the division | segmentation piece after a test was observed visually, and the following reference | standard judged.
○ ・ ・ ・ There is no sticking of the split piece with cleaning water × ・ ・ ・ There is sticking of the split piece with cleaning water

  In the test piece of the example, since the concave and convex portions are formed on the surface of the synthetic resin foam divided piece, there is no sticking of the divided piece with washing water, and the divided piece is uniformly on the white solid steel plate. Since it abuts against artificial dirt, there was no generation of unwashed and high cleaning performance.

  On the other hand, since the test piece of the comparative example is a smooth surface with no irregularities formed on both sides of the divided pieces, the adjacent divided pieces are attached with washing water and are integrated with each other against artificial dirt on the white solid steel plate. As a result of the contact, the unwashed portion was generated in the portion where the divided pieces did not contact, and the cleaning performance was poor.

  The operation | movement and effect | action of the brush piece 1 comprised as mentioned above and the washing brush 9 for car wash machines are as follows.

  In the brush piece 1, even if adjacent divided pieces 4 or adjacent divided pieces 4 overlap each other during a car wash, a concave portion 5 and a convex portion 6 are formed on the surface of the divided piece 4. Therefore, the contact area is small compared to the case where the divided pieces made of smooth surfaces overlap each other, and it is difficult to adhere. That is, the smooth surface side of the divided piece 4 rides on the adjacent divided piece 4 or the convex portion 6 of the adjacent divided piece 4 adjacent to each other. Therefore, the overlapping divided pieces 4 can be easily separated and separated from each other only by the impact force when the brush piece 1 contacts the surface to be cleaned. Since the sticking is prevented, the divided pieces 4 come into contact with the surface to be cleaned without being integrated, so that generation of unwashed parts is suppressed and the divided pieces 4 are also applied to fine uneven portions of the surface to be cleaned. Touch and scrape off dirt on the surface to be cleaned. Further, since the slits 3 are formed in steps in the divided pieces 4, the divided pieces 4 having different lengths sequentially contact the surface to be cleaned with different pressing forces, so that it becomes easier to remove dirt. In this embodiment, the concave portion 5 and the convex portion 6 are formed on the surface of the divided piece 4 that contacts the surface to be cleaned, but the concave portion is formed on the back surface of the divided piece 4 that contacts the surface to be cleaned. Needless to say, even when the protrusions 5 and the protrusions 6 are formed, the divided pieces 4 are prevented from sticking with the washing water or the like.

  Further, since the adjacent divided pieces 4 are not stuck and integrated with the washing water or the like, the brush pieces 1 are prevented from freezing in winter, particularly in cold regions.

  Moreover, the washing brush 9 for a car wash machine can have high washing performance with no washing residue because the divided pieces 4 formed on the brush piece 1 do not stick to each other with washing water or the like.

  In this embodiment, only the synthetic resin foam 2 is used as the material of the brush piece 1. However, if the synthetic resin foam 2 is provided as described above, the synthetic resin foam 2 is used. And other materials such as woven fabric, non-woven fabric, knitted fabric, artificial leather, synthetic leather, artificial leather such as artificial leather, genuine leather, film-like resin composition, synthetic resin fiber, synthetic resin sheet, thermoplastic elastomer The brush piece 1 may be formed by joining, superimposing, or using together with a sheet or the like.

  Further, in this embodiment, a closed cell foam is used as the synthetic resin foam 2 constituting the brush piece 1, but an open cell foam can also be used. An open cell refers to a bubble that is not completely surrounded by a bubble wall and communicates with an adjacent bubble. Therefore, a part of the wall surface is missing between adjacent bubbles, so that liquid such as washing water flows to the inside of the foam. Therefore, since the brush piece 1 can contain more cleaning water during the car wash than the closed cell, it is possible to clean the brush piece 1 with reduced interfacial tension against dirt. The interfacial tension refers to a tension that acts in the direction of reducing the contact area at the boundary surface where the solid and the liquid are in contact. Therefore, the decrease in interfacial tension means that the contact area between the solid and the liquid is increased, and the contact area between the solid dirt and the washing water that is the liquid absorbed by the brush piece 1 is increased. Dirt is easy to remove. The selection of closed cells or open cells is appropriately determined according to the usage environment of the washing brush 9 for a car wash machine.

  Further, the structure of the washing brush 9 for a car wash machine is not particularly limited, and can be set in a timely manner according to the purpose of use.

3 (a) is a partial plan view of a brush piece in the second embodiment of the present invention, FIG. 3 (b) is a partial plan view of a brush piece in another embodiment, and FIG. The perspective view of the brush piece in other embodiment, FIG.4 (b) is a partial side view at the time of the division | segmentation piece of the brush piece of Fig.4 (a) overlapping, FIG.4 (c) is another implementation. It is a partial side view at the time of the division | segmentation piece of the brush piece in a form overlapping.

  In FIG. 3 (a), the brush piece 11 is composed of a flat synthetic resin foam 12, and the synthetic resin foam 12 is subdivided into a plurality of subdivisions by a slit 13 having a circular hole 17 at one end. A piece 14 is formed, and a concave portion 15 and a convex portion 16 are formed on the surface of the divided piece 14 over the entire area in the slit forming region 18.

  The brush piece 11 is disposed on a shaft body (not shown) so that the divided pieces 14 abut against the surface to be cleaned, and the concave portion 15 and the convex portion 16 abut against the surface to be cleaned. (Not shown).

  The operation and action of the brush piece 11 are as follows.

  When the divided piece 14 comes into contact with the surface to be cleaned, the pitch, tar, wax, silicone, etc. that are firmly attached to the surface to be cleaned by the edge portion of the convex portion 16 formed over the entire area of the divided piece 14. Oily scale dirt, iron powder, etc. are scraped off. Therefore, the cleaning performance is greatly improved.

  In addition, since a plurality of convex portions 16 are formed on the surface of one piece of divided piece 14, when one piece of convex portion 6 is formed on one piece as in the divided piece 4 of the first embodiment. In comparison, even if the divided piece 14 comes into contact with the surface to be cleaned and the convex portion 16 at a specific location is worn, if the other convex portion 16 is not worn, the sticking of the divided piece 14 due to washing water or the like is prevented. In addition, high cleaning performance is maintained for a longer period of time.

  Next, the brush piece in other embodiment is demonstrated using FIG.3 (b).

And a space is created between the smooth surface of the segment piece 34a and the recess 35 of the segment piece 34b, and air flows into the space. Therefore, the adjacent divided pieces 34a and 34b have a smaller contact area compared to the case where they are overlapped by surface contact, and can be separated quickly and easily even if they overlap due to the resistance of air. As a result, it is possible to prevent the divided pieces 34a and 34b from being separated from each other and sticking together with washing water or the like to be integrated.

  Moreover, as shown in FIG.4 (c), the trough-shaped recessed part 45 and the mountain-shaped convex part 46 are formed in the single side | surface of the brush piece 41 which consists of synthetic resin foams 42, and the adjacent division | segmentation piece 44a, 44b is formed. If they overlap during a car wash, the smooth surface side of the split piece 44a rides on the convex portion 46 of the split piece 44b by point contact, and the smooth surface of the split piece 44a and the concave portion 45 of the split piece 44b. A space is created between them, and air flows into the space. Therefore, the adjacent divided pieces 44a and 44b have a smaller contact area compared to the case where they are overlapped by surface contact or line contact, and are separated very quickly and easily even if they overlap due to air resistance. Therefore, it is possible to prevent the divided pieces 44a and the divided pieces 44b from separating from each other and sticking together with cleaning water or the like for a longer period of time.

  In addition, the form which forms the recessed part 15, 25, 35, 45 or / and the convex part 16, 26, 36, 46 not only on the surface of the synthetic resin foam 12, 22, 32, 42 but on the back surface is also employable.

(Example 3)
FIG. 5 is a partially enlarged plan view of a brush piece in the third embodiment of the present invention.

  In FIG. 5, the brush piece 51 is made of a synthetic resin foam 52, and a plurality of divided pieces 54 that are subdivided by a slit 53 having a circular hole 57 at one end are formed on the synthetic resin foam 52. In addition, a concave portion 55 and a convex portion 56 are formed over the entire surface of the synthetic resin foam 52. The slit 53 is formed with an inclination angle θ that forms an acute angle with respect to the side edge portion 50 of the synthetic resin foam 52. The inclination angle θ may be less than 90 °, but is set to be 60 ° or more and less than 90 ° from the viewpoint of preventing sticking of the divided pieces 54 with cleaning water or the like and improving the cleaning performance. desirable.

  The brush piece 51 has a shaft body (so that the divided piece 54 comes into contact with the surface to be cleaned and the surface of the synthetic resin foam 52 on which the concave portion 55 and the convex portion 56 are formed is on the side in contact with the surface to be cleaned. A car brush washing brush (not shown) is configured.

  The operation and action of the brush piece 51 are as follows.

  Compared to the case where the slit 53 is formed at a substantially right angle with respect to the side edge portion 50 of the synthetic resin foam 52, the divided piece 54 draws an oblique cleaning locus even when the adjacent divided pieces 54 overlap. However, it is easier to leave. Further, since the plurality of divided pieces 54 of the brush piece 51 subdivided by the slits 53 abut on the surface to be cleaned while drawing a cleaning trajectory oblique to the surface to be cleaned, the divided pieces 54 provide fine uneven portions of the surface to be cleaned. Since the dirt is removed and the adjacent divided pieces 54 sequentially come into contact with the trajectory drawn by the slit 53 that does not easily come into contact with the surface to be cleaned, and the dirt is removed. Is prevented. Therefore, the cleaning performance is greatly improved.
