SOLUTION: A rectangular paper metal fitting 2 having a movable positioning rod 5 and a fixing screw 3, which is mounted on a conventional cutter 1 and can be cut to a fixed size freely when cutting shoji paper, is used for positioning for shoji paper cutting. Utensils.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention attaches to a conventional cutter and uses it. After attaching the shoji paper to the shoji frame, the unnecessary shoji paper on the four sides of the shoji frame can be cut to a fixed size. It is about.

[0002]

[Prior art]

 Conventionally, this type of cutting method involves cutting the unnecessary top and bottom, left, and right sides of the shoji paper on the four sides of the shoji frame using a cutter guide or ruler that contacts the outside of the shoji frame multiple times. There is known a method of cutting to a predetermined width with a safety razor, a round blade cutter, a folding blade cutter, or the like while shifting.

[0003]

[Problems to be solved by the invention]

 The conventional technique has a problem that when a ruler is used, it is necessary to take time and work while shifting the ruler a plurality of times to cut off the unnecessary paper that has protruded.

[0004] There is also a problem that the cutting line meanders and it is difficult to cut at a constant width.

[0005] Since the cutting is performed while being shifted upward, there is also a problem that it takes time and extra nerves to match the end of the thin cutting line with the starting end.

When working with a cutter guide or a ruler, there is a problem that the ruler or the cutter guide is damaged with the blade edge, and the work must be performed using both hands, which is inconvenient.

[0007] The present invention has been made in view of such problems of the conventional technology, and the purpose is to attach it to a conventional cutter and attach it to four sides of the top, bottom, left and right sides of a shoji frame. An object of the present invention is to provide a cutting position locating tool that can cut an unnecessary unnecessary shoji paper with a predetermined width neatly, efficiently and reliably.

[0008]

[Means for Solving the Problems]

 In order to achieve the above object, the positioning device for cutting shoji paper according to the present invention is a square metal fitting which can be inserted into and removed from a handle portion of a cutter used by folding a conventional blade edge. In this case, the square metal fitting may have a lip groove-shaped structure in which one side surface is notched.

[0009] The rectangular metal fitting is provided with a fixing screw hole at the upper part, two parallel holes into which a positioning rod with a left end bent is inserted at the lower part, and is fitted through, and the right end is bent.

[0010] The positioning rod is engaged with the handle in a cross shape by tightening a fixing screw. The positioning rod may be provided with a groove on the lower side of the handle of the cutter so that it does not rattle, and may be fitted and engaged.

The bending directions of the left end and the right end of the positioning rod are perpendicular to each other and can be bent even after being inserted into the two parallel holes. In this case, either one of the left end and the right end may be bent.

[0012]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. 1 to 3, a conventional cutter 1 is provided with an upper fixing screw hole 4 in an insertable / removable square metal fitting 2 of the present invention, and a positioning rod 5 hole 6 and a hole 7 are provided in parallel at a lower portion. .

The fixing screw 3 is fastened to the fixing screw hole 4 and fixed to the handle 11 of the cutter 1.

The positioning rod 5 is inserted into the positioning rod holes 6 and 7, and both ends are bent at right angles. The positioning rod 5 can be provided with a groove 10 on the lower side of the cutter 1 and can be engaged with the handle 11 so as not to rattle.

In FIGS. 4 and 5, the positioning rod 5 can be moved right and left by loosening the fixing screw 3 so that the inside of the left end 8 or the right end 9 is applied to the outside of the shoji frame 12, and the cutting edge is unnecessary. Tighten the fixing screw 3 to the width of 13 to fix the positioning rod 5.

[0016]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

The edge of the shoji paper 13 is adjusted to the width of the unnecessary shoji paper 13, and the cutter 1 mounted in the present invention is moved in the cutting direction at an appropriate angle, so that the four sides of the shoji paper can be moved in a fixed width in a short time. The unnecessary shoji paper 13 can be efficiently cut in a straight line.

The unnecessary adjustment of the width of the paper 13 is simple, no skill is required, the work can be performed without meandering, and with a constant width and without using extra nerves.

The left end 8 and the right end 9 are oppositely bent at right angles, so that the cutter 1 equipped with the shoji paper cutting positioner of the present invention can be used at an appropriate angle to raise the height above the surface of the shoji paper. Since the handle 11 is used while holding the handle, the work can be performed with one hand without breaking or damaging the shoji paper pasted on the left end 8 and the right end 9.
