1. Cleaning Instrument As shown in FIG. 1, the cleaning instrument 1 is an instrument for cleaning a surface S to be cleaned, such as a wall or window glass. The cleaning tool 1 includes a cleaning unit 2, a support unit 3, and a grip unit 4.

(1) Cleaning Unit The cleaning unit 2 contacts the surface S to be cleaned when the cleaning worker cleans the surface S to be cleaned. The cleaning unit 2 cleans the surface S to be cleaned. The cleaning unit 2 is a transparent blade. Since the cleaning unit 2 is transparent, the cleaning worker can work while looking at the surface S to be cleaned through the cleaning unit 2. The cleaning unit 2 has a flat plate shape extending in a predetermined direction. The cleaning unit 2 extends along the surface S to be cleaned while being in contact with the surface S to be cleaned. The cleaning unit 2 is made of a transparent resin.

  As a resin which comprises the cleaning part 2, a urethane resin, a silicone resin, an acrylic resin, a polyvinyl chloride, polyethylene, a polypropylene, a polyethylene terephthalate etc. are mentioned, for example.

  The resin constituting the cleaning unit 2 preferably does not contain a plasticizer. Therefore, defects such as the surface of the cleaning unit 2 becoming sticky due to the bleeding of the plasticizer can be suppressed.

  The cleaning unit 2 is preferably made of a urethane resin. If it is a urethane resin, the Shore hardness of the cleaning unit 2 can be adjusted to a desired value without containing a plasticizer.

  The urethane resin may be a polyisocyanate component (eg, 1,5-pentamethylene diisocyanate, 1,6-hexamethylene diisocyanate, 1,3 or 1,4-bis (isocyanatomethyl) cyclohexane, isophorone diisocyanate, norbornene diisocyanate, xylylene diisocyanate) It is a polymer of a raw material containing an isocyanate, toluene diisocyanate and the like) and an active hydrogen group-containing compound (for example, a high molecular weight polyol such as a polyether polyol and a polyester polyol, and a polyol such as a low molecular weight polyol such as a polyamine).

  In order to produce a urethane resin, for example, a polyisocyanate component and a polyol component are added in a predetermined blending ratio and an isocyanate index (ratio of isocyanate group concentration (NCO concentration) of polyisocyanate component to hydroxyl group concentration of polyol component) to 100. The resulting mixture is cured in a predetermined mold by mixing at the multiplied value, NCO concentration / hydroxyl concentration × 100).

  The Shore hardness of the cleaning unit 2 is, for example, A15 or more, preferably A60 or more, and for example, D74 or less, preferably A95 or less.

  If the Shore hardness of the cleaning unit 2 is equal to or more than the lower limit value and equal to or less than the upper limit value, the cleaning unit 2 can be prevented from damaging the surface S to be cleaned. Further, if the Shore hardness of the cleaning unit 2 is equal to or more than the lower limit value and equal to or less than the upper limit value, the cleaning unit 2 can easily follow the surface S to be cleaned. It can improve.

  Further, the total light transmittance of the cleaning unit 2 is, for example, 70% or more, preferably 95% or more, and usually 100% or less. It is defined as "transparent" that the total light transmittance is 70% or more.

  If the total light transmittance of the cleaning unit 2 is equal to or more than the lower limit value, the cleaning worker can easily view the surface S to be cleaned through the cleaning unit 2.

The shape of the support portion 3 is not limited as long as the support portion 3 can support the cleaning portion 2. For example, the support unit 3 may be a clip sandwiching a part of the cleaning unit 2. Moreover, the support part 3 may be transparent. When the support portion 3 is transparent, the cleaning worker can more easily view the surface S to be cleaned. The support portion 3 is preferably made of a transparent and hard resin.

  As resin which comprises the support part 3, a urethane resin, a silicone resin, an acrylic resin, a polyvinyl chloride, polyethylene, a polypropylene, a polyethylene terephthalate, a polycarbonate etc. are mentioned, for example.

(3) Grip part The grip part 4 is a part which a cleaning worker can grasp. The grip 4 is connected to the support 3. The grip 4 may be manufactured integrally with the support 3. The grip 4 may be manufactured separately from the support 3 and may be movable relative to the support 3. The grip portion 4 extends in a direction intersecting the direction in which the cleaning portion 2 extends. The grip 4 is connected to the support 3 at the center in the direction in which the support 3 extends. The grip portion 4 has a flat plate shape. In addition, the shape of the grip portion 4 is not limited as long as the cleaning worker can grasp it. For example, the grip 4 may be a rod. Moreover, the grip part 4 may be transparent. If the grip 4 is transparent, the cleaning worker can more easily view the surface S to be cleaned. Moreover, it is excellent in the designability as all the cleaning devices 1 containing the cleaning part 2, the support part 3, and the grip part 4 are transparent.

  In addition, as resin which comprises the grip part 4, resin similar to resin which comprises above-described support part 3 can be mentioned.

2. Method of Using Cleaning Device Next, a method of using the cleaning device 1 will be described.

  The cleaning worker wets the surface S to be cleaned with a liquid detergent or water, and then removes dirt on the surface S using the cleaning tool 1 as shown in FIG.

Remove wet stains with liquid cleaners and water.

  At this time, if the cleaning tool 1 is moved in a state where hard particles such as sand are sandwiched between the surface S and the cleaning unit 2 of the cleaning tool 1, the surface S may be damaged.

  Therefore, when the cleaning worker looks at the surface S through the cleaning unit 2, when hard particles such as sand are seen, such hard particles are removed or Remove dirt while taking care that hard particles do not damage the surface S.

  This can prevent the surface S from being damaged.

  In addition, the use of the cleaning tool 1 is not restricted to the use which removes the stain | pollution | contamination of surface S. FIG. For example, even if the surface S is not dirty, the cleaning tool 1 can be used to scrape the liquid adhering to the surface S.

  In addition, when cleaning the surface S as described above, the cleaning worker can work while viewing the surface S being cleaned via the cleaning unit 2. Therefore, the cleaning worker feels a sense of achievement every time they scrape with the cleaning tool 1 and can enjoy and work.

  Moreover, since the designability is excellent if the cleaning device 1 is transparent, the work can be enjoyed more.

3. Operation and Effect According to the cleaning device 1, the cleaning unit 2 for cleaning the surface S to be cleaned is a transparent blade.

  Therefore, the cleaning worker can view the surface S to be cleaned through the cleaning unit 2. As a result, the cleaning worker notices via the cleaning unit 2 even if hard particles adhere to the part of the surface S to be cleaned that is hidden by the cleaning unit 2 be able to.

  As a result, the cleaning tool 1 can be moved after removing hard particles or while paying attention not to damage the surface S to be cleaned, while suppressing damaging the surface S to be cleaned. The surface S to be cleaned can be cleaned.

  Moreover, according to this cleaning tool 1, the support part 3 which supports the cleaning part 2 is also transparent.

  Therefore, the cleaning worker can more easily view the surface S to be cleaned.

  Moreover, according to this cleaning tool 1, the grip part is also transparent.

  Therefore, the cleaning worker can more easily view the surface S to be cleaned.

  Moreover, according to this cleaning tool 1, the Shore hardness of the cleaning part 2 is A15 or more and D74 or less.

  Therefore, it can suppress that the cleaning part 2 damages the surface S of cleaning object. Further, the cleaning unit 2 can easily follow the surface S to be cleaned, and the drainage performance can be improved.

  Moreover, according to this cleaning tool 1, the cleaning part 2 consists of resin which does not contain a plasticizer.

  Therefore, defects such as the surface of the cleaning unit 2 becoming sticky due to the bleeding of the plasticizer can be suppressed.

  Moreover, according to this cleaning tool 1, the cleaning part 2 consists of urethane resin.

  Therefore, the Shore hardness of the cleaning unit 2 can be adjusted to a desired value without containing a plasticizer.
