Abstract

An object of the present invention is to provide a caulking spatula used for smoothing a caulking material by removing the internal bubbles and voids by pressing the caulking material injected into the joint. SOLUTION: The blade body 1 is formed so that the thickness of the blade body 1 becomes thinner from the blade body mounting part of the grip part 2 to the tip of the blade body 1 and becomes the thinnest at the tip part. The broken line 5 is displayed on the plate surface. [Selection] Figure 1

Description

  The present invention relates to a caulking spatula used for smoothing a caulking material by pressing a caulking material injected into a joint to remove internal bubbles and voids.

  As a conventional technique, the thickness of the blade body is the same from the blade body mounting part of the grip part to the tip of the blade body. The worker cut and processed the blade body according to the application at the site, and made a self-made spatula by attaching an appropriately processed backer to the blade body.

Utility Model Registration No. 3164890

  Conventionally, the caulking spatula has the same wall thickness from the blade body mounting part of the grip part to the tip of the blade body, so the flexibility of the blade body is poor and the unevenness of the surface of the object is rough. Because the blade body is hard, it is not flexible and smooth, it is difficult to feel the strength of the delicate fingertips in places that require precision on the uneven part, and the blade body vibrates and creates a chatter pattern on the surface The surface is not finished cleanly. Furthermore, when cutting the blade body according to the site application, it took time and effort to draw a line at the cutting point.

  In order to achieve the above problem, the blade body is formed such that the thickness of the blade body becomes thinner from the blade body mounting part of the grip part to the tip of the blade body, and the tip part becomes the thinnest, thereby making the blade body flexible. A broken line such as a straight line or a semicircle is displayed at appropriate intervals on the plate surface.

  As described above, the present invention is formed such that the thickness of the blade body becomes thinner from the blade body mounting part of the grip part to the tip of the blade body and becomes the thinnest at the tip part, so that the blade body has flexibility. Therefore, the operator cuts the blade body according to the application at the site, processes it, and attaches a properly processed backer to the blade body to produce a self-made spatula. Because the blade body is flexible even in places where the roughness of the rough surface is required, it is easy to give a sense of strength with a delicate fingertip, and the surface is finished beautifully without creating a chatter pattern.

  Also, when removing excess caulking material, the blade body is flexible, reducing the resistance received by the tip of the blade body, and reliably pressing to remove internal bubbles and air gaps. You can clean the surface finish.

  Since the blade body is flexible, the blade body 1 bends and deforms according to the amount of force applied by the operator, and the operation of moving the caulking material in a predetermined direction becomes smooth and works smoothly. This reduces the burden on the operator's wrist and fingertips and improves work efficiency.

  Furthermore, since the broken lines are displayed at appropriate intervals on the plate surface of the blade body at appropriate intervals, the desired straight line, semicircle, etc. displayed on the plate surface when cutting the blade body according to the field application If the broken line is cut, it is possible to save troubles such as drawing a line at the cut portion, so that the work efficiency is improved.

  Front view of the present invention   Side view of the present invention

  In the present invention, the blade main body is formed so that the thickness of the blade main body becomes thinner from the blade main body mounting portion of the grip portion to the tip of the blade main body and becomes the thinnest at the front end portion, thereby giving the blade main body flexibility. Hereinafter, an embodiment will be described with reference to the accompanying drawings.

1 and 2 are a front view and a side view of the present invention.
Reference numeral 1 denotes a blade body made of a thin metal and is substantially rectangular. 2 is a grip part of the blade body mounting part, which is made of wooden or synthetic resin. Reference numeral 3 denotes a blade body mounting portion. Reference numeral 4 denotes a rivet, which fixes the blade body 1 and the grip portion 2. A broken line 5 is displayed on the plate surface of the blade body 1.

  Since the present invention is configured as described above, the thickness of the blade body 1 is gradually reduced from the blade body mounting portion 3 of the grip portion 2 to the tip of the blade body 1, and the tip portion is formed to be the thinnest. The blade body 1 provided with the blade is appropriately processed into the blade body 1 by cutting, processing, etc., a desired straight line, semicircular broken line or the like displayed on the plate surface according to the use at the site. I make a spatula made by sticking a backer.

  As for the usage method, the operator holds the grip part 2 of the blade body 1 with his hand, the bucker attached to the tip of the blade body 1 is wider than the blade body 1 and has a side surface inclined, and the shape of the tip Is V-shaped, and is performed by pressing a backer against the surface of the filled caulking material and moving the filled caulking material in a predetermined direction.

  In addition, since the blade body 1 is made flexible even in places where the surface of the object is rough, the blade body 1 is flexible so that it is easy to give a sense of strength with a delicate fingertip. The surface is beautifully finished. And since the blade body 1 is made flexible, the resistance received by the backer attached to the tip of the blade body 1 is reduced, and it can be reliably pressed to remove internal bubbles and air gaps. The surface finish can be made beautiful, and the blade body 1 bends and deforms according to how the operator's force is applied. The operation of moving the caulking material in the specified direction is also smooth, so the operator can work smoothly. This reduces the burden on the wrist and fingertips and improves work efficiency.

Since the broken lines such as straight lines and semi-circles are displayed at appropriate intervals on the plate surface of the blade body at appropriate intervals, the blade body is cut along the desired broken line according to the application at the site. This saves you the trouble of drawing a line and improves work efficiency.
