Angle bisecting ruler

Abstract

To provide an angle bisector ruler capable of easily bisecting an angle of one-half even in a place of an arbitrary angle by using the angle bisector ruler, although the angle of an external corner and an internal corner is almost 90° and a 45° fixing ruler can be used in the place of the external corner and the internal corner, but cannot be used in a place of an arbitrary angle.SOLUTION: A gear 1 is fixed to one side of a straight ruler 3 superposed on a base straight ruler 5, a gear 2 is fixed to one side of another straight ruler 4 rotatably attached to one side on the base straight ruler 5, and the gears 1 and 2 are engaged with each other side by side with the straight ruler 3 and rotatably attached to one side on the base straight ruler 5.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] To provide an angle bisecting ruler that can easily halve any angle when attaching decorative material to any angled corner, whereas decorative material from two directions is cut obliquely at a half angle and then fitted together at the corner when attaching decorative material to any angled corner. [Background technology]

[0002] The edges of the floor and wall, the edges of the wall and ceiling, and the corners of the decorative materials attached to the wall are usually 90°, so they are marked with a 45° ruler, but when the edges of the wall are not necessarily 90° and have any angle, for the edges of the corners you place a straight ruler on two sides of the wall, draw both lines, place a protractor on it and bisect the angle, and for the edges of the corners you place a straight ruler on both sides, draw a line on the inside of the ruler, place a protractor on it and bisect the angle, which is a very tedious job. Summary of the Invention [Problem to be solved by the invention]

[0003] To provide an angle bisecting ruler that can easily halve an angle of an outside or inside corner, which has hitherto been a very troublesome task of drawing out the lines of two sides of the outside or inside corner, placing a protractor on the line and reading the halved angle, in order to halve any angle of the outside or inside corner. [Means for solving the problem]

[0004] The angle bisecting ruler of the present invention is an angle bisecting ruler that has a gear (1) fixed to one side of a straight ruler (3), a gear (2) fixed to one side of a straight ruler (4), straight rules (3) and (4) aligned horizontally, gears (1) and (2) meshed together, and gears (1) and (2) attached to one side of a base straight ruler (5) so that they can rotate freely.

[0005] [Effects of the Invention]

[0005] In this invention, even if the angle of an outside corner or an inside corner is arbitrary, the angle can be easily divided into two equal parts by simply pressing two straight rulers 3 and 4 against the outside corner or inside corner surface. [Brief explanation of the drawings]

[0006] [Figure 1] FIG. 1 is a plan view of an angle bisector according to the present invention. [Figure 2] This is a front view of an angle bisecting ruler. [Figure 3] The two straight rulers are now open. [Figure 4] The two straight rulers are now open. [Figure 5] Two straight rulers are placed at a given angle. [Figure 6] The bisection of an arbitrary angle is being transferred onto the decorative material. DETAILED DESCRIPTION OF THE INVENTION

[0007] Figures 5 and 6 show an embodiment of an angle bisecting ruler according to the present invention. In Figure 5, the angle bisecting ruler is mounted on a base straight ruler 5, with gear 1 fixed to one side of one straight ruler 3 and gear 2 fixed to one side of straight ruler 4, and the two gears are meshed together and attached to the ends so that they can rotate freely.

Claims

[Claim 1] This angle bisecting ruler is characterized in that a gear (1) is attached to one side of a straight ruler (3), a gear (2) is attached to one side of a straight ruler (4), the straight rulers (3) and (4) are aligned horizontally, the gears (1) and (2) are meshed, and the gears (1) and (2) are rotatably attached to one side of a base straight ruler (5).
