JPS6032961Y2 - Cutting ruler for portable circular saw - Google Patents

Description

[Detailed description of the invention] This invention relates to a cutting ruler for a portable horizontal circular saw, and the details thereof will be explained next.

When cutting a wooden board or wooden pillar with an electric circular saw (portable cross-cutting circular saw), the cutting line is simply drawn on the wooden board or water pillar, and the circular saw is advanced along that line to cut. However, it was not possible to cut it accurately to match the cutting line.

Therefore, the present invention provides a circular saw ruler edge that can be used for cutting at right angles or arbitrary angles.

This proposal basically consists of a width rod 1, a reference rod 2, and a ruler plate 3. The width rod 1 has a flat abutment surface a in the longitudinal direction, and the abutment surface a is cut. Since it is to be placed along the side of the wood A, the size and length should be appropriate.

The reference rod 2 is installed inside the width rod 1, and the contact surface a of the width rod 1
A deep hole is provided on the side from one end, and the reference rod 2 is inserted into the hole so that the width rod 1 can be freely inserted and removed from one end of the width rod 1 along the contact surface a.

It also has a fixing mechanism for fixing the reference rod 2 at an arbitrary position. To give an example of the fixing mechanism, the reference rod 2 is fixed so that one surface of the reference rod 2 is strongly pressed against one surface of the deep hole. A pressing bolt 5 for pressing is attached to the width rod 1.

The ruler plate 3 has a linear ruler edge, and is pivotally attached to the upper surface of the width rod 1 at a position close to the one end (reference eave side) with a shaft 4,
It is rotatable and is provided with a fixing mechanism for fixing the ruler plate 3 to the width rod at a constant angle.

The fixing mechanism involves drilling a semicircular induction hole 6 centered on the shaft 4 in the ruler plate 3, protruding a screw rod 7 from the width rod 1 through the induction hole 6, and screwing a screw nut 8 into the screw rod 7. It is something that comes together.

The structure of the main plan is as described above, and to use the main plan ruler,
Place the abutment surface a of the width rod 1 on the side f of the wood A, rotate the ruler plate 3 so that the angle of the cutting line g drawn on the wood A matches the angle of the edge of the ruler, and place it where they match. Tighten the screw nuts 8 to fix the ruler plate 3, and separate the proposed ruler from the set of wood A.
Next, the reference rod 2 is positioned.

To position the reference rod 2, touch the side surface d of the stand C of the saw body B with the edge of the ruler, extend it until the tip of the reference rod 2 touches or does not touch the side surface of the circular saw 0, and press it. bolt 5
Tighten to fix the reference rod 2.

Alternatively, if the reference rod 2 is particularly made of wood, stretch and fix the reference rod 2 appropriately, and cut the reference rod 2 with a circular saw 0 while moving the side d of the stand C along the edge of the ruler. You may do so.

Then, place the contact surface a against the side surface f of the wood A, position the tip of the reference rod 2 on the cutting line g, and align the table side surface d of the saw body B along the edge of the ruler. When the saw body B is advanced, the wood A is cut along the cutting line g without bending.

As described above, the present invention is a very convenient ruler for cutting wood at right angles or any arbitrary angle, and since the position of the reference rod can be determined at any time, it is possible to use a circular saw from the side of the table according to the standards of the saw body. It also has the advantage of being usable even if there is a difference in distance.
