Abstract

<P>PROBLEM TO BE SOLVED: To provide a ruler for a circular saw with a guide by which anyone can execute a cutting operation by the circular saw simply and correctly. <P>SOLUTION: A projecting groove 3 extending parallel with longitudinal direction is prepared in one side of the circular saw ruler, a recessed groove 4 is prepared in positions which are conformable with this projecting groove, and a guide 2 for the circular saw formed so as to slide the top of the circular saw ruler is prepared. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

Detailed Description of the Invention

Technical field to which the invention belongs

  The present invention is in the field of circular saw rulers with guides.

  When cutting a straight line with a circular saw, in order to cut to the required size, the circular saw has been moved according to the black line so far, or two marks on the workpiece are marked, and a ruler is aligned with the mark. Cutting along the side of the ruler.

Problems to be solved by the invention

  The problem to be solved by the present invention is to simultaneously advance these two different operations, which are performed while pressing along to the side when cutting along a ruler. When we were not careful, either work was neglected, and a strong attention and skill were required to perform an accurate cutting work. The rational integration and simplification of two different tasks.

Means for solving the problem

  The present invention is formed so as to slide on a circular saw ruler provided with a convex groove extending parallel to the longitudinal direction on one side of a circular saw ruler and having a recess at a position matching the convex groove. It features a circular saw guide, and the work that moves forward while pressing down matches the direction of sliding, and by sliding the groove, smooth and rational work and easy and accurate cutting are possible. A ruler for a circular saw with a guide that makes it easy for anyone to cut quickly.

  The circular saw guide (2) has a grooved surface (4) extending in the longitudinal direction on the surface of the circular saw. Either a new surface plate is manufactured, or the material is made of plastic, special resin or light metal. It is made of a material that has good properties and sliding properties, and is fixed and bonded to the bottom surface of a circular saw plate with an adhesive or double-sided tape. Similarly, for the circular saw guide ruler (1), make a new one with a length of convex part (3) extending in the longitudinal direction and adding the size of the circular saw surface plate to the work piece, It is made of plastic or special resin or light metal material, and it is used as a guide ruler by fixing and adhering to the plate material with adhesive or double-sided tape.

FIG. 1 shows the structure of a circular saw guide ruler (1) provided with a convex groove (3). The shape of a circular saw guide (2) provided with a concave groove (4) that is fixedly bonded to the bottom surface of a circular saw surface plate is shown.
In FIG. 2, the shape of the concave and convex grooves is a shape as shown by a to h, and it is desirable to take into consideration the frictional resistance when sliding with a structure that does not shift laterally, and it is desirable to provide several grooves in parallel.

The invention's effect

  The guide ruler has an effect of remarkably improving the accuracy with respect to lateral deviation at the start and end of cutting by making the length longer than the length of the circular saw surface plate added to the cut piece to be cut. This is a circular saw ruler with a guide that combines the grooves and pushes them forward, so it does not require any extra concentration and concentrates on the cutting work, realizing a quick and accurate work.

  It is a perspective view of the circular saw ruler with a guide based on this invention.   It is the shape of a ditch | groove based on this invention.   It is a circular saw shape.

Claims (1)

  For circular saws that are formed to slide on a ruler for circular saws, with a convex groove extending in parallel with the longitudinal direction on one side of the ruler for circular saw, and a groove in the position that fits this convex groove. Guided circular saw ruler characterized by the provision of a guide.
