A ruler with a groove that can be adjusted to any position

Abstract

To provide a ruler that enables selection of any groove position. [Solution] A grooved ruler without markings is made on the slider surface of a transparent plastic ruler without markings, at equal intervals of 10 mm, into which the tips of a pencil or ballpoint pen fit, and an opening is made 10 mm from the surface opposite the slider surface, parallel to the slider surface, leaving 5 mm on both ends of the longitudinal direction of the ruler without markings. A grooved ruler without markings is attached to a ruler with markings, the opposite side of the markings of the ruler without markings is aligned with the opposite side of the slider surface of the ruler without markings, and the ruler without markings is stacked on top of the grooved ruler without markings, with the ruler without markings underneath and the grooved ruler without markings on top, and female threads for two mounting bolts for the grooved ruler without markings are provided 20 mm apart in the longitudinal center of the openings in the grooved ruler without markings, making it possible to change the position of the grooved ruler.

Description

[Technical field]

[0001] The present invention relates to a repositionable slotted ruler. [Background technology]

[0002] One idea is to use a grooved ruler that can be repositioned. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Real No. 3108593 [Patent Document 2] Real total 02-144493 [Patent Document 3] Practical publication Showa 59-124195 Summary of the Invention [Problem to be solved by the invention]

[0004] A grooved ruler allows you to set the grooves at a uniform interval so that you can easily draw lines without looking at the scale. I have seen tools that allow you to mark points, but the position of the groove can be selected at will. There is a requirement for tools. [Means for solving the problem]

[0005] A transparent plastic ruler with no scale is placed on the slider surface, with pencil marks at 10mm intervals. Make a groove for the tip of the ballpoint pen, and place it 10 mm from the surface opposite the slider surface. Parallel to the slider surface Ruler without scale A ruler with a groove without markings, with 5mm openings at both ends in the longitudinal direction, was changed to a ruler with markings. Ruler with scale The other side has a memory stick Ungraded grooved ruler Align the opposite sides of the slider surface and place the scale ruler underneath. Ungraded grooved ruler Place on top and stack. Ungraded grooved ruler Established in In the longitudinal center of the opening Ungraded grooved ruler Female thread for two mounting bolts A ruler with grooves that can be adjusted at 20mm intervals. Effect of the Invention

[0006] The grooved ruler allows for a wider working range. [Brief description of the drawings]

Claims

[Claim 1] A transparent plastic ruler with no scale is placed on the slider surface, with pencil marks at 10 mm intervals. Make a groove for the tip of the ballpoint pen, and place it 10 mm from the surface opposite the slider surface. A slotted ruler without a marking was placed parallel to the slider surface, with an opening of 5 mm left at both ends of the longitudinal direction of the slotted ruler, and the marking of the slotted ruler was placed on the slotted ruler. Align the other side with the other side of the slider surface of the grooved ruler without markings, and place the ruler with markings underneath. Stack the ruler with a groove without a scale on top, and insert two female threads for the ruler with a groove without a scale at the center of the longitudinal direction of the opening in the ruler with a groove without a scale, leaving a gap of 20 mm between them. A grooved ruler that can be adjusted to any position.
