Challenges to solve the invention

According to the above-mentioned conventional technique, it is difficult to work on a construction site having a small area with a spatula in which a long spatula plate is fixed to a mounting bracket of a flexible broom. Also, in order to fit a long or short spatula made of hard synthetic resin into a narrow construction site, it is difficult to cut the spatula with a cutter knife, and if you do not use a gold saw, etc. Cannot be easily cut. In order to cut the spatula more accurately, it was necessary to draw a line with a ruler or the like to cut the spatula.

Since the long spatula and the short spatula fixed to the mounting bracket of the flexible broom are not lightened, the burden on the operator during construction is heavy.

Further, in the case of a spatula consisting of a flat plate and a short spatula plate, it is difficult for the fingers to come into close contact with the flat plate during work, so the spatula is not stable, so it is difficult to continue the work uniformly on the flat surface of the urethane waterproof material.

In addition, since the conventional spatula is made of hard synthetic resin and lacks in flexibility, move it while making the tip of the comb of the spatula come in contact with the surface of the pool of retin waterproof material, and make the plane of the urethane waterproof material uniform in a streak pattern. In this case, since the spatula is made of a hard synthetic resin, the tip of the comb of the spatula often hits the base and scratches the surface due to the force applied.

When changing the shape of the spatula comb, it is necessary to remake the spatula die, which takes a lot of time and cost.

Therefore, it is possible to cut a long spatula accurately in a short time according to the construction site, without damaging the base without adding force and changing the shape of the spatula comb without cost. In addition, the problem is to be solved by further reducing the weight of the spatula body.

Means for solving the problem

The spatula body is formed of flexible polyethylene foam. The spatula body is a long spatula having a grip at one end and comb-shaped combs regularly arranged at the other end, and is formed to be thin from the grip to the tip of the comb. Broken lines are shown at appropriate intervals on the plate surface of the spatula body. Laser processing is used for the comb-shaped molding.

Further, the problem is solved by arranging a flexible elastic body, which is easily deformable by pressing the finger at an appropriate position on the upper surface of the grip, at appropriate intervals on the upper surface with broken lines. It is a thing. The elastic body may be arranged on the upper surface of the inclined surface from the grip portion to the tip of the spatula body. Further, as a slip stopper, a concave portion into which a finger enters may be provided on the upper surface of the inclined surface from the grip portion to the tip of the spatula body.

Effect of device

Since the spatula body is made of a lightweight polyethylene foam, the spatula body is lighter than the conventional spatula, which reduces the burden on the operator during construction.

And in order to fit a long or short spatula made of conventional hard synthetic resin to the construction site, a spatula cannot be easily cut because a spatula is needed when cutting the spatula. However, since the long spatula body of the present invention is made of lightweight polyethylene foam, work efficiency can be improved because it can be easily cut to a size that fits the construction site with a cutter knife or the like. Good.

Furthermore, when cutting with a cutter knife etc. to a size suitable for the construction site, dashed lines are displayed at appropriate intervals from the grip part of the spatula body to the tip of the comb part. If the broken line of the elastic body is used as a guide, it can be cut in a short time, and the next work process can be immediately performed, so that work efficiency is improved.

Also, with a spatula consisting of a conventional flat plate and a short spatula plate, it is difficult for the fingers to come into close contact with the flat plate of the spatula during work, so the spatula becomes unstable during work, and the flat surface of the urethane waterproof material is evenly streaked. Although it was difficult to continue, the present invention has an elastic body that can be easily deformed by applying finger squeeze at appropriate places on the upper surface of the grip or the inclined surface, so that the fingertips are soft when working. The fingers are extremely slippery because they are in close contact with the elastic body, and there is little feeling of fatigue even when the fingers are squeezed for a long time, and therefore the spatula is stable and the plane surface of the urethane waterproof material can be uniformly finished in a streak shape.

Furthermore, the conventional spatula is lacking in flexibility because it is made of hard synthetic resin, and the tip of the comb of the spatula often hits the base material strongly and scratches it with the addition of force. The spatula body of the device is made of flexible polyethylene foam, and the spatula progresses smoothly by increasing the flexibility by making it narrow from the grip part to the tip of the comb part. Therefore, the work time is shortened and the fatigue of the arm is also reduced. Even if the tips of the spatula's combs hit the base strongly due to the force applied, it is a soft polyethylene foam and will not scratch.

Further, laser processing is used to form the comb-like shape of the spatula body, so that the comb-like shape can be immediately changed. Therefore, it is not necessary to remake the mold in order to change the shape of the comb pattern of the conventional spatula, resulting in a reduction in time and cost.

A spatula having a substantially rectangular spatula body made of flexible polyethylene foam, having a grip portion at one end of the spatula body, and comb-shaped portions regularly arranged at the other end, Dashed lines are shown at appropriate intervals at appropriate points on the upper surface from the grip to the tip of the comb. Laser processing is used for the comb-shaped molding. An elastic body that can be easily deformed by finger compression is provided at an appropriate position on the upper surface of the grip portion. An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 are a front view and a side view of the present invention.
A spatula body 1 is made of a flexible polyethylene foam. A grip portion 2 is formed at one end of the spatula main body 1, and a comb-like comb portion 3 is formed at the other end. Reference numeral 4 denotes a broken line, which is displayed on the upper surface of the grip portion 2 to the upper surface of the comb portion 3 at appropriate intervals. The grip portion 2 is formed so that the thickness thereof becomes thin toward the tip of the comb portion 3, and the comb portion 3 having a comb shape is formed by laser processing. Reference numeral 5 is a soft elastic body, which is arranged at an appropriate position on the upper surface of the grip portion 2 and can be easily deformed by pressing the finger. Reference numeral 6 is a broken line, which is displayed at an appropriate interval on the upper surface of the elastic body.

Since the present invention is constructed as described above, since the long rectangular spatula body 1 is formed of a flexible polyethylene foam, the spatula body 1 can be cut into a size suitable for a construction site. A broken knife 4 which is displayed at an appropriate interval from the grip portion 2 to the upper surface of the comb portion 3 or the broken line 4 of the elastic body 5 is cut with a cutter knife or the like, but the spatula body 1 is made of flexible polyethylene foam. Since it is a body, it can be easily cut. As a method of use, an operator holds the grip portion 2 of the spatula body 1 that is appropriately cut in size, and moves it while abutting the tip of the comb portion 3 on the surface of the pool of urethane waterproof material. During this work, the fingertips come into close contact with the grip portion 2 and the elastic body 5 provided on the upper surface of the inclined surface, so that the fingers are extremely slippery and a moist feeling is obtained, and even if the finger is squeezed for a long time, a feeling of fatigue is felt. Therefore, the spatula is stable and the flat surface of the urethane waterproof material can be uniformly finished in a streak shape. The spatula is stable and the flat surface of the urethane waterproof material can be evenly finished. Since the spatula main body 1 is made of a lightweight polyethylene foam, the spatula body 1 is lighter than the conventional spatula, so that the operator's arm fatigue is reduced during construction. In addition, since the spatula body 1 is formed of a flexible polyethylene foam, the base is not scratched by the force applied. Furthermore, since the laser processing is used to form the comb shape of the spatula body 1, it is possible to immediately respond to the change of the comb shape, so it is necessary to remake the mold in order to change the comb shape of the spatula. It also saves time and costs.

The present invention is used in the spatula manufacturing industry.
