Description of the Invention (/) [Technical Field] (Please read the notes on the back before filling out this page) This invention is about freely adjustable angle fixtures, especially about being able to easily and correctly find any angle Of the fixture. [Technical background] For example, in general, the spire roof (herringbone wood) of a Japanese-style house is set in the shape of a closed palm. When constructing such a blast board, the end of the board must be inclined For cutting, the inclined cutting ends of the two boards are aligned with each other and fixed to the pointed roof. In addition, when constructing an interior, the peripheral frame between the wall surface and the ceiling or the skirting plate between the wall surface and the floor, cut off the peripheral frame plate or skirting board diagonally at the corners, and align the inclined ends of the two peripheral frame boards or skirting board. Be fixed. Generally, when cutting the end of such a wind board, peripheral frame or skirting board, if the operator cuts the end of the board in an oblique direction depending on the feeling, a gap will be created at the joint surface of the wind board, peripheral frame or skirting board. And make the appearance worse. Printed by the Shellfish Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. On the other hand, when looking for angles in the construction of houses, etc., the so-called square square 10 shown in Figure 1 is mostly used, but the square 10 can only obtain 45 °, Fixed angles of 90 ° and 135 ° "Recently, there are special forms of roofs, or houses on deformed (complex terrain) land. In this case, the desired angle cannot be obtained with a square ruler 10. . A folding ruler 20 that connects the long and short rulers to each other with "ends" as shown in Fig. 2 has been put into practical use. For example, when you want to cut the angle of the wind board, open the two rulers of the folding rule 20 as shown in Figure 3 (a), and then, 3 paper sizes apply the Chinese National Standard < CNS) A4 size (210 X 297) Public ")-A7 434400« __B7_ V.

The four shafts connected by the ® line form four sides. An equal parallelogram; and a reference ruler having a straight portion at least in part, along which the rotation axis between the pair of first feet and the rotation axis between the pair of second feet are connected to support the two rotations And at least one of the rotation axes can move freely in the diagonal direction of the parallelogram; the angle formed by the pair of first feet or the angle formed by the pair of second feet or One or more of the angles formed by the first or second ruler and the reference ruler are used as the required angle. One of the features of the present invention is that two pairs of rulers (the first and second rulers) are used. Link for rotation Freely, by connecting the parts of the four rotation axes with straight lines to form parallelograms of equal length on the four sides, according to this, it can be deformed in the same plane while maintaining the above-mentioned parallelograms, and 'in its diagonal position A reference ruler is provided to support the parallelogram, and specifically, it passes through a pair of rotation axes (vertex) between the first ruler and a pair of rotation axes (vertex) between the second ruler. The support form of the parallelogram may be such that at least one of the two vertices can move freely in the diagonal direction. According to the above structure, a pair of first feet or a pair of second feet can be used.

Description of the invention (+ ) Degrees. Also, 'Because of the reference ruler, the angle formed with either one pair of the first ruler or one pair of the second ruler' is often an angle formed by the first ruler or an angle formed by the second ruler. As long as the 1st or 2nd ruler is set to any angle, half of the angle can be easily and surely determined. In addition, the freely adjustable angle jig of the present invention has a great effect when it is used for the same purpose as the conventional folding rule, but it can also be used for other purposes, such as a jig installed as a cutting machine and used For the purpose of cutting metal materials or other materials to arbitrary angles ^ The above-mentioned reference ruler 'and the first and second rulers may be linear as long as at least a part of each of the functions of the ruler is linear, for example, the first and second rulers The outer edge of the ruler 'will make the side edge of either side of the reference ruler linear, that is, the function of the freely adjustable angle ruler in this example can be achieved, but if the appearance and ease of use are considered, it is better to make the two edges of each ruler linear. . "Although the materials of the above-mentioned standard ruler and the above-mentioned first and second rulers are not particularly limited", in consideration of wear resistance and strength, metal materials such as aluminum (or aluminum alloy) or stainless steel, or relatively hard synthetic resin materials, Or a combination of these materials is preferred.
