Embodiments of the present invention will be described below.
Embodiment 1 of the Invention

  1 to 3 show a first embodiment of the present invention.

  The cutting ruler 1 according to Embodiment 1 is used when cutting a member to be cut 13 such as a plate material or a column material as shown in FIG. 3, and as shown in FIG. 1 and FIG. The guide plate 2 is made of a colorless and transparent synthetic resin having a substantially right-angled isosceles triangular plate shape. Here, the “substantially right-angled isosceles triangular plate shape” means a plate shape in which a rectangular plate-like portion to which a second addressing member 6 described later is attached is integrally connected to a right-angled isosceles triangular plate-like portion. Means. The guide plate 2 includes a first guide edge 3 at a portion corresponding to one side of two sides sandwiching a right angle of a substantially right-angled isosceles triangle that is a planar figure of the guide plate 2, and A second guide edge 4 is provided at a portion corresponding to the hypotenuse of a substantially right-angled isosceles triangle that is a planar figure. Further, the guide plate 2 has an arcuate slit 7 centered on the rotation center CT1 located in the vicinity of the right-angled apex of a substantially right-angled isosceles triangle that is a plan view of the guide plate 2. It penetrates in the direction (FIG. 2 (b) left-right direction).

  Further, a portion corresponding to the other side (hereinafter abbreviated as “the other side of the guide plate 2”) of two sides sandwiching a right angle of a substantially right-angled isosceles triangle that is a planar figure of the guide plate 2 is shown in FIG. As shown in FIGS. 1 to 3, the first addressing member 5 made of a synthetic resin in the shape of a strip plate addressed to the side surface 13a of the member 13 to be cut is 0 in the directions of arrows M and N around the rotation center CT1. It is rotatably mounted within an angle range of 40 °. Further, a second addressing member 6 made of a synthetic resin in the form of a strip plate is attached to the same portion so as to face the first addressing member 5 positioned at a rotation angle of 0 ° with the guide plate 2 interposed therebetween. ing. Further, a strip-shaped synthetic resin stopper 9 is fixed to the second addressing member 6 so as to position the first addressing member 5 at a rotation angle of 0 °. The guide plate 2 has a scale 8 such as “10”, “20”, “30”, “40” indicating the rotation angle of the first addressing member 5 with respect to the other side of the guide plate 2 inside the slit 7. It is provided along.

  Further, as shown in FIG. 2, the cutting ruler 1 includes a first addressing member 5 that is positioned at an arbitrary rotation angle of 0 to 40 ° with respect to the other side of the guide plate 2. Fixing means 10 that can fix the addressing member 5 to the guide plate 2 is provided. The fixing means 10 includes a male screw member 11 provided on the first addressing member 5 so as to move along the slit 7 in accordance with the rotation of the first addressing member 5, and a female screw that is screwed into the male screw member 11. It is comprised from the member 12. FIG. As shown in FIG. 3, the second addressing member 6 is formed with a U-shaped notch 6 a corresponding to the lower end of the slit 7.

  Since the cutting ruler 1 has the above-described configuration, the cutting member 13 is cut using the cutting ruler 1 according to the following procedure.

  First, in the addressing member positioning step, the first addressing member 5 is positioned at a predetermined rotation angle with respect to the other side of the guide plate 2 according to the cutting angle α of the member 13 to be cut. Here, the cutting angle α of the member to be cut 13 means an angle inclined from the width direction (arrows A and B directions) of the member to be cut 13 as shown in FIG. 3, and the counterclockwise direction is minus (−). The clockwise direction is represented by plus (+).

  At this time, when the cutting angle α of the member 13 to be cut is specifically determined several times, the rotation angle of the first addressing member 5 is set using the scale 8. For this purpose, the scale 8 is adjusted to an angle obtained by inverting the sign of the cutting angle α of the member 13 to be cut. For example, when the cutting angle α of the member to be cut 13 is 0 °, the front side surface 5 a of the first addressing member 5 is made to coincide with “0” of the scale 8. At this time, the first addressing member 5 is in a state in which the side surface 5 b then contacts the stopper 9. Further, when the cutting angle α of the member 13 to be cut is −10 °, the front side surface 5a of the first addressing member 5 is made to coincide with “10” of the scale 8 as shown in FIG. Furthermore, when the cutting angle α of the member to be cut 13 is −35 °, the front side surface 5a of the first addressing member 5 is made to coincide with “35” of the scale 8 as shown in FIG. Thus, if the scale 8 is used, the rotation angle of the first addressing member 5 can be easily set. Therefore, the cutting ruler 1 is excellent in usability in this respect.

  On the other hand, when the cutting angle α of the member to be cut 13 is not known several times, the scale 8 cannot be used. By copying to 1, the rotation angle of the first addressing member 5 can be set. For example, when considering a site where a floor finishing material (flooring) is laminated as a member to be cut 13 on the upper side of the floor base material, the first addressing member 5 is addressed to the side surface of the floor finishing material, and the surface of the inner wall material The cutting angle of the floor finishing material can be copied to the cutting ruler 1 by applying the first guide edge 3 or the second guide edge 4 to the edge. As a result, the rotation angle of the first addressing member 5 can be set.

  In this way, in the state where the first addressing member 5 is positioned at a predetermined rotation angle, the process proceeds to the addressing member fixing step, and the female screw member 12 is fastened to the male screw member 11 to thereby fix the first addressing member 5 to the guide plate. Fix to 2. Then, the cutting ruler 1 is in a state of being fixed to the guide plate 2 in a state where the first addressing member 5 is positioned at a predetermined rotation angle with respect to the other side of the guide plate 2. In this way, the first addressing member 5 can be fixed to the guide plate 2 simply by fastening the female screw member 12 to the male screw member 11. Therefore, the cutting ruler 1 is excellent in usability in this respect.

  Finally, the process proceeds to a cutting execution process, and the member to be cut 13 is cut using a cutting tool (not shown) such as an electric circular saw. For this purpose, as shown in FIG. 3, the front side surface 5a of the first addressing member 5 of the cutting ruler 1 is addressed to the side surface 13a of the member 13 to be cut, and the guide plate 2 of the cutting ruler 1 is covered with the left hand. While being pressed against the cutting member 13, the cutting tool 13 is gripped by the right hand, and the cutting tool 13 is moved forward along the first guide edge 3 of the cutting ruler 1 to cut the member to be cut 13.

  At this time, as described above, the first addressing member 5 of the cutting ruler 1 is positioned and fixed at a predetermined rotation angle corresponding to the cutting angle α of the member 13 to be cut. When 5 is directed to the side surface 13a of the member 13 to be cut, the inclination angle of the first guide edge 3 with respect to the width direction of the member to be cut coincides with the cutting angle α of the member 13 to be cut. Moreover, the cutting ruler 1 is pressed against the member to be cut 13 in this state. Therefore, the cutting work of the member 13 to be cut can be performed accurately.

  Further, as described above, since the guide plate 2 is transparent in the cutting ruler 1, when the cutting ruler 1 is directed to the member to be cut 13, the member to be cut 13 is transparent under the guide plate 2. Looks. Therefore, the cutting ruler 1 is excellent in usability in this respect.

  Here, the cutting operation of the member 13 to be cut by the cutting ruler 1 is completed.

  Here, the cutting operation for cutting the member 13 to be cut while the cutting tool is placed along the first guide edge 3 of the cutting ruler 1 has been described. However, the second guide edge 4 can be used instead of the first guide edge 3. However, since the second guide edge 4 is inclined by 45 ° with respect to the first guide edge 3, when the rotation angle of the first addressing member 5 is set using the scale 8, It is necessary to adjust the scale 8 to an angle obtained by subtracting the cutting angle α of the member 13 to be cut from 45 °. For example, when the cutting angle α of the member 13 to be cut is + 35 °, the front side surface 5a of the first destination member 5 is made to coincide with “10” of the scale 8 as shown in FIG.

  Thus, since the cutting ruler 1 has two guide edge portions (first and second guide edge portions 3 and 4) formed on the guide plate 2, the cutting ruler 1 is used to cut. When the member 13 is cut, the two guide edges can be used properly according to the cutting angle α of the member 13 to be cut and the preference of the operator. Therefore, the cutting ruler 1 is excellent in usability in this respect.

  Further, unlike the conventional cutting ruler 1, when the cutting ruler 1 is used, it is not necessary to insert and attach the guide plate body to the guide substrate in advance. Therefore, the labor before use of the cutting ruler 1 can be saved.

  Further, since the guide plate 2 is composed of one part, the structure of the cutting ruler 1 can be simplified.

  Moreover, since the 2nd addressing member 6 is attached to the cutting ruler 1 as mentioned above, the cutting ruler 1 can be turned over and used as necessary. Therefore, the cutting ruler 1 is excellent in usability in this respect.

Further, as described above, the cutting ruler 1 has a substantially isosceles right triangular plate shape as described above, so that the first and second guide edges 3, 4 with respect to the width direction of the member 13 to be cut. The inclination angles are 0 ° and 45 °, that is, the angles most frequently used for cutting the member to be cut. As a result, these angles can be cut quickly without rotating the first addressing member 5. Therefore, the cutting ruler 1 is excellent in usability in this respect.

In this case, when the cutting ruler 1 is turned upside down and used, the third addressed member is appropriately rotated according to the cutting angle α of the member to be cut 13 so that the member 13 to be cut has a desired cutting angle α. It becomes possible to cut.

  In the first embodiment described above, the cutting ruler 1 in which the plan view of the guide plate 2 is a substantially right-angled isosceles triangle (that is, a substantially right-angled triangle having two acute angles of 45 °) has been described. However, the plane figure of the guide plate 2 is not limited to a substantially right-angled isosceles triangle, and may be a right-angled unequal triangle with two acute angles of 30 ° and 60 °, for example.
