DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curing tape mainly used for caulking or painting inside and outside corners of a building (hereinafter, also referred to simply as "tape"). The present invention relates to a tool that can be bent and pasted in a shape.

[0002]

2. Description of the Related Art As is well known, when caulking or painting is applied to a wall H in a room and a corner F of a floor F, a ceiling, or an orthogonal wall, a curing tape T having an adhesive on one surface is applied along the corner S. For example, at the corner K where the floor F and the two wall surfaces H are orthogonal to each other, it is necessary to apply the curing tape T at right angles on each surface. In this case, conventionally, FIG.
As shown in the figure, cut the tape once before the corner K,
From there, tapes were pasted again at right angles.

[0003]

However, as described above, the work of cutting the tape at each corner and superimposing the tape at right angles cannot be performed because the hand is obstructed by the wall, and the tape is not adhered. It was difficult to cut because the agent was applied, and it was rather troublesome and inefficient because it got stuck on the hand.

In this conventional method, when the tape is peeled off after caulking or painting, the continuity of the tape is cut off at each corner, and each time the end of the tape stuck to the floor or wall surface is removed from the floor or wall. It was necessary to peel off and lift off its end.

[0005] In addition, the end of the curing tape at the corners is peeled off because the tape is thin and the adhesive tape is pressed down to the corners of the floor or wall even though it has a weak adhesive strength. In this case, workability was extremely poor and peeling was not easy.

[0006]

[Procedure for Use] A case where the curing tape T is stuck to the corner K of the floor F in a right angle will be described with reference to FIGS.

As shown in FIG. 6, a tape T is applied from left to right, and a tool having an open end near the corner K as shown in FIG. When the tape T is sandwiched by the rotary plate 18 and the lock pin 25, the lock pin 25 is automatically fitted into the lock groove 30 as shown in FIG. You. At this time, the leading end of the tape T is put on the upper end of the rotating plate 18.

Next, the ruler blade 5 is aligned in parallel with the upper edge of the tape T, and the folding guide blade 15 is moved to a position parallel to the right wall H by a predetermined distance. At this time, in the tool, since the guide blade 4 is not in contact with the lower surface of the half-shaped conical portion 17 and the frictional resistance of the surface of the rotary plate 18 is small, even if the tape lower surface is coated with an adhesive, The tool moves easily.

Next, when the lever 23 of the tool is operated inward, the locking claw 20 is retracted to the support 11 via the hanging piece 24, so that the rotating plate body 18 is moved inward from above by the action of the helical spring 14. Then, as shown in FIG. 7, the bent guide blade 15 overlaps the upper surface of the ruler blade 5 in a parallel state. Thereby, the tape T is guided by the folding guide blade 15 to form a right angle.

Next, the front of the tape T is extended in parallel along the right wall H, and the tape T is adhered to the floor F when pressed down with a finger. Therefore, when the tool is pulled out from the tape, the tape is bent at a right angle. The part is as shown in FIG.

By pressing the tape T in the state shown in FIG. 8 by sliding the finger from the front to the front, a right-angled corner can be formed by bending one tape as viewed from a plane as shown in FIG.
