Claims

[Scope of Claim for Utility Model Registration] 1. A ruler device for cutting a tread fitting groove and a riser plate fitting groove in a side plate material of a staircase, comprising: a first ruler part for cutting the tread fitting groove; The second ruler part for cutting the riser board fitting groove is configured symmetrically, and both ruler parts are connected at a connecting part so that the slide can be adjusted freely, and the ruler part is inserted in the width direction of the side plate material. A fixing member that is tightened and fixed to the side plate material as it is passed, a ruler body that is to be disposed diagonally on the upper surface of the side plate material, and a base end of the ruler body that is supported by the fixing member. a first reversing support mechanism that is capable of reversing the ruler body via a hinge portion, and a connecting portion that is configured to adjust the distance between the fixing members in the first and second ruler portions. A connecting shaft is provided along both sides of the side plate material, and a second reversing support mechanism for supporting the tip end side of the ruler body is disposed on one of the connecting shafts. The ruler bodies in the section are designed to be able to set symmetrical angular positions, and by tilting them inward with their respective inversion support mechanisms, both ruler bodies can be set in symmetrical angular positions.
A ruler device for cutting step grooves, characterized in that it is configured to form a dogleg shape. 2. The ruler device for cutting step grooves according to claim 1, wherein a frame member that forms a substantially rectangular shape with the ruler body is attached to the ruler body. 3 The hinge portions of the first and second reversal support mechanisms are rotatably adjustable in the horizontal direction, and the rotational fulcrums are slidably adjustable with respect to the fixed member and one of the connecting shafts, respectively;
2. A ruler device for cutting step grooves according to claim 1, wherein the angle of the ruler body can be variably adjusted by slidingly adjusting each pivot portion. 4. The ruler device for cutting step grooves according to claim 1, wherein the ruler body is attached to the first and second reversing support mechanisms so as to be slidable and adjustable.
