Description

  The present invention relates to a paint squeegee, and more particularly to a paint squeegee that can be applied with a waterproof paint in a suitable and easy manner by making the structure of a gripping member specific.

  The waterproofing method mainly includes the waterproofing method for the paint film and the sheet prevention method. Among these, the waterproofing method for the paint film is a liquid waterproof paint containing urethane waterproof material, asphalt waterproof material, etc. It is a method of applying a waterproof coating such as a floor, a wall, and a rising portion to form a waterproof coating by drying (for example, Patent Documents 1 and 2).

  Tools for applying liquid waterproof paint include paint squeegees, roll coaters, sprayers, brushes, etc. The types and properties of waterproof paints, the necessity of heating the waterproof paints, the type of foundation (concrete It is used properly depending on whether it is used in combination with sheet prevention or the like), place (whether it is a floor surface or a rising part, etc.), the shape of the groundwork (whether there are protrusions or irregularities, etc.), the waterproof area, and the application (waterproof level).

  "Squeegee" is used for applying liquid paint, removing moisture, cleaning windows, silk screen printing, paint application, etc. by using blades. Of these, liquid waterproof paint is applied. As a coating squeegee to be used, one as shown in FIG. 2 has been conventionally used.

  However, in the conventional coating squeegee as shown in FIG. 2, when a liquid waterproof paint is applied, the force pressing the waterproof paint on the ground surface cannot be applied uniformly in the vertical direction, In some cases, the force for rubbing the waterproof paint could not be applied uniformly in the lateral direction. Also, it is difficult to grasp the gripping member 120, and as the application operation continues, the hand becomes tired, or a sufficient force cannot be applied due to fatigue of the hand, etc., and the waterproof paint is applied uniformly. It was difficult.

That is, it is possible to provide a coating squeegee that can be easily grasped by the gripping member and can perform the coating operation suitably without getting tired of the hand.

In general, in order to apply a high-viscosity waterproof paint sufficiently uniformly, it is necessary to apply a certain amount of force, but it is difficult to apply a sufficient force uniformly with conventional squeegees. It was difficult unless it was an expert.
According to the painting squeegee of the present invention, the gripping member is easier to grip as compared to the conventional painting squeegee 110 as shown in FIG. ) And the lateral direction (application direction), and it becomes easy to spread the waterproof paint uniformly.

It is a perspective view which shows an example of the structure of the squeegee for painting of this invention. It is a perspective view which shows an example of the structure of the conventional coating squeegee.

  Hereinafter, although this invention is demonstrated, this invention is not limited to the following embodiment, It can deform | transform and implement arbitrarily.

FIG. 1 shows an example of the structure of a painting squeegee 10 according to the present invention. The squeegee 10 for painting is comprised from the holding member 20 and the application | coating member 30 made from rubber | gum or resin in FIG.
The gripping member 20 is a part for the operator to grip when performing the work, and the application member 30 may be abbreviated as a waterproof paint (hereinafter simply referred to as “paint”) on the base (construction surface). It is a part used when applying.

In FIG. 1, the gripping member 20 is composed of two flat plates 22 </ b> A and 22 </ b> B, and the coating member 30 is sandwiched between the two flat plates 22 </ b> A and 22 </ b> B constituting the gripping member 20. It is fixed to the member 20.
There is no particular limitation on the method for fixing the gripping member 20 and the application member 30. Particularly when the gripping member 20 is made of wood, it is easy to grip, physically strong, and easy to drill, and a fixing method (not shown) such as a nail, screw, or staple is preferably used. it can.
As the fixing method, regardless of the material, the fixing method is preferable because it is difficult to come off and is simple. In addition, as a method for fixing the gripping member 20 and the application member 30, a method using an adhesive or the like may be used.

The applicator member 30 includes at least a portion fixed to the gripping member 20 and an exposed portion 31 that is not fixed.
Preferably, as shown in FIG. 1, the application member 30 includes a portion that is sandwiched between two flat plates 22 </ b> A and 22 </ b> B constituting the gripping member 20 and fixed to the gripping member 20, and two flat plates. It is comprised from the exposed part 31 which is not pinched.
The exposed portion 31 is a portion used for spreading the paint, has flexibility, and bends during application to facilitate uniform application of the paint.
When spreading the paint, the paint squeegee 10 is moved in the direction of arrow D in FIG. 1, and the paint is uniformly applied by the flexibility of the exposed portion 31 at that time.

  Although the shape of the exposed portion 31 is not particularly limited, as shown in FIG. 1, the portion fixed to the gripping member 20 has a long side, and the exposed width portion from the gripping member 20 has a short side. Preferably there is. With such a shape, it is easy to spread the paint uniformly on a wide surface. The application member 30 itself is not particularly limited, but is preferably a rectangular plate as shown in FIG.

The ratio of the surface area of the exposed portion 31 to the entire surface area of the coating member 30 is preferably 0.3 or more and 0.7 or less, more preferably 0.4 or more and 0.6 or less, and 0.45 or more and 0.55 or less. Particularly preferred.
When the ratio is too large, the application member 30 is difficult to be fixed to the gripping member 20, and in particular, the application member 30 may not be stably fixed to the two flat plates of the gripping member 20 and may be easily detached. On the other hand, if the ratio is too small, the fixing portion of the application member 30 becomes an obstacle when the gripping member 20 is provided with a through-hole 20a described later, and the exposed portion 31 is not sufficiently bent during application. , It may be difficult to apply the paint uniformly.

The thickness 30h of the coating member 30 and the exposed portion 31 is preferably 0.3 cm or more and 2 cm or less, more preferably 0.5 cm or more and 1.5 cm or less, and particularly preferably 0.7 cm or more and 1.2 cm or less.
If the lower limit of 30h is equal to or greater than the above, the application member 30 is unlikely to be broken, cracked, deformed, etc., and can be used for a long time. When the upper limit of 30h is equal to or less than the above, the exposed portion 31 is sufficiently bent when applied, and the coating squeegee 10 can be lightened and the operation becomes easy.

The width 31s of the exposed portion of the coating member 30 (the portion used for spreading the paint) is preferably 2 cm to 5 cm, more preferably 2.3 cm to 4 cm, and particularly preferably 2.7 cm to 3.5 cm. preferable.
When 31s is within the above range, the exposed portion 31 can be easily bent appropriately during application, the force can be sufficiently transmitted to the painted surface, and the paint can be spread uniformly.

The length 30L of the side (long side) perpendicular to the application direction D of the application member 30 is preferably 15 cm to 50 cm, more preferably 20 cm to 40 cm, and particularly preferably 25 cm to 35 cm.
When the upper limit of 30L is not more than the above, coating unevenness in the long side direction when the paint is spread is difficult to occur. Further, when the lower limit of 30L is equal to or more than the above, the application work can be efficiently advanced, and the through portion 20a for inserting a finger into the gripping member 20 can be easily provided.

  The tip of the exposed portion 31 of the application member 30 may be a flat shape as shown in FIG. 1 or a comb-like shape (not shown). In either case, the effect of the present invention that the gripping member 20 can be easily grasped, the work is easy, and the coating can be performed uniformly is exhibited.

The material of the application member 30 is not particularly limited as long as it is a rubber or resin that is excellent in durability, weather resistance, etc., and has appropriate flexibility and elasticity suitable for application. Specifically, for example, chloroprene rubber, neoprene, etc. Rubbers such as rubber, isoprene rubber, styrene butadiene rubber, acrylonitrile butadiene rubber, ethylene butadiene rubber, butyl rubber, silicone rubber, urethane rubber, silane modified polymer rubber; and resins such as polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, and acrylic resin .
The material of the coating member 30 is chloroprene rubber, neoprene rubber, or the like from the viewpoint of durability of the paint to the solvent, easy spreading of the paint having high viscosity, and having suitable flexibility and elasticity. Foam is particularly preferred.

The gripping member 20 includes at least two flat plates 22A and 22B, and has a structure in which the application member 30 is sandwiched and fixed by the two flat plates 22A and 22B. The material of the gripping member 20 is not particularly limited, but is preferably wooden.
As shown in FIG. 1, the gripping member 20 has a reinforcing plate 21 between the two flat plates 22A and 22B, and the thickness of the reinforcing plate 21 is substantially the same as the thickness 30h of the application member. Is particularly preferred. In that case, the surfaces of the two flat plates 22A and 22B are parallel to each other.
When the thickness of the coating member 30h is relatively thick, it is more preferable that the coating member 30 is not easily detached from the gripping member 20 when the thickness is as described above.

  Although not shown, when the coating member 30 is thin, the reinforcing plate 21 may not be provided, and the coating member 30 may be directly fixed so that the flat plates 22A and 22B sandwich the coating member 30.

The thicknesses of the flat plates 22A and 22B are each preferably 0.2 to 1 cm, more preferably 0.25 to 0.7 cm, and particularly preferably 0.3 to 0.5 cm.
Since the thickness of the entire gripping member 20 is determined by the thickness of the coating member 30 (thickness of the reinforcing plate 21) and the thickness of the flat plates 22A and 22B, a preferable range is also determined by them.
When the thickness of the flat plates 22A and 22B and the gripping member 20 is within the above range, the strength is sufficient and the gripping member 20 can be easily gripped.
Further, when the thickness of the flat plates 22A and 22B is equal to or less than the above upper limit, the flat plates 22A and 22B do not get in the way during the coating operation, and the coating member 30 can be brought close to the construction surface, so that the coating operation is easy. become.

  There is no particular limitation on the shape of the flat plates 22A and 22B. As an example, as shown in FIG. 1, a shape in which the apex of the portion not fixed to the coating member 30 is chamfered is preferable, as a basic shape is rectangular. As mentioned.

In the present invention, the gripping member 20 has a penetrating portion 20a into which fingers can be inserted.
Since the gripping member 20 has the penetrating portion 20a, the gripping member 20 can be suitably gripped by inserting a finger (finger other than the thumb) into the penetrating portion 20a during the application operation. The application work can be performed without getting tired, and the force can be easily transmitted to the application surface (construction surface, groundwork), and it becomes easy to spread the paint uniformly.

The shape and size of the penetrating portion 20a are not particularly limited as long as fingers other than the thumb can be inserted without difficulty.
The penetrating portion 20a is formed by providing an opening in the gripping member 20, but is particularly formed by providing an opening in each of the two flat plates 22A and 22B. The openings provided in the two flat plates 22A and 22B are not limited, but are preferably provided at the same position for ease of manufacture and ease of use.

From the viewpoint of ease of manufacture and the like, an example of the penetrating portion 20a is a rectangular penetrating portion 20a as shown in FIG.
Furthermore, in the case of a rectangular shape, the length of the long side is preferably 8 cm or more and 20 cm or less, more preferably 9 cm or more and 15 cm or less, and particularly preferably 10 cm or more and 13 cm or less. Further, the length of the short side is preferably 1.5 cm to 3.5 cm, particularly preferably 2 cm to 3 cm.
When the lengths of the long side and the short side are within the above range, it is easy to insert a finger, and the position of the finger during the application operation is easily determined, so that the paint can be spread sufficiently uniformly.
It is preferable from the point which does not damage the said point and fingers that each vertex inside the penetration part 20a is R-processed.

  In addition, although not limited, for example, if there are irregularities that match the shape of the fingers on the long side (not shown), it becomes easier to grip the gripping member and easily apply force evenly. From the above point, it is preferable that the unevenness is provided on the side of the penetrating portion 20a that is gripped with a finger and on which the force is applied, that is, on the side opposite to the “exposed portion of the coating member”.

  Although there is no particular limitation on the position of the penetrating portion 20a, it is preferable that it is substantially in the center of the gripping member 20 from the viewpoint that it is easy to apply a force, a design margin, and the like.

When the gripping member 20 has the reinforcing plate 21, the thickness of the reinforcing plate 21 is substantially the same as the thickness 30h of the coating member, and the two flat plates 22A and 22B are parallel as surfaces. preferable.
A fixing method between the reinforcing plate 21 and the flat plates 22A and 22B is not particularly limited, but a fixing method using a nail, a staple, or the like is preferable because it can be easily fixed and is difficult to come off.

  When there is the reinforcing plate 21, it is preferable that the edge 21a of the reinforcing plate shown in FIG. 1 is aligned with the long sides of the openings provided in the flat plates 22A and 22B. In this way, when the gripping member 20 is gripped, there is no level difference in the portion where the finger (the finger other than the thumb) touches, so that it becomes easier to apply force and it is difficult to damage the finger.

  In the coating squeegee 10 as shown in FIG. 2 used for applying the waterproof paint, it is essential that the application member (blade) 30 is made of rubber or resin, and the flat plates 22A and 22B are not limited, but both It is preferably wooden. Although not limited, it is particularly preferable that the reinforcing plate 21 is also made of wood, and the entire gripping member 20 is made of wood.

The painting squeegee of the present invention is particularly suitable for painting a paint having a high viscosity such as a urethane waterproof material and an asphalt waterproof material. The asphalt waterproof material may be a rubber asphalt waterproof material, an asphalt waterproof material in a heat method, or an asphalt waterproof material in a so-called cold method used at room temperature. The painting squeegee of the present invention is particularly suitable for painting a walking paint.
