Description

[Detailed description of the invention] This invention interrupts the drawing that is in progress in order to replenish the ink midway through drawing with a conventional coracoid.
Leave space between the coracoid tips to refill the coracoid tips.Pour ink directly into the coracoid tips from the ink container, as this will stain the coracoid tips, so first transfer the ink to a piece of paper or something between the coracoids. Ink is replenished to the tip of the coracoid by applying it to the coracoid.
Even the simplest drafting requires time and frequent replenishment of ink, readjusting the spacing between the coracoid tips each time the ink is replenished, and changing the trial line to a different one to match the thickness of the already drawn line. Not only is ink wasted as you draw it on paper, but you also have to adjust the spacing to match the thickness of the line you are drawing because of the difference in line thickness during the drawing. We often experience that the ink runs out before we know it and we have to refill it.

Furthermore, the conventional coracoid alone does not have a knife or scissors for cutting things such as paper or cloth, a compass for drawing circular lines, or a jig for measuring the intervals between drawing lines, and a commercially available fountain pen type drawing tool is not required. Even in this case, I keep a set of pens with 0.1 mm intervals and use them by replacing them according to the thickness of each line, but in this case too, if I try to use them at different dates, Ink may clog in the pen tip and make it unusable, requiring a specialist to repair it, which may not be an emergency.

In addition, each of these drawing tools is separate and must be replaced and used, so there is a drawback that it takes time and effort to use.

The purpose of this invention is to solve the above-mentioned drawbacks of the conventional coracoid and drafting tools.The purpose of this invention is to provide a hole for refilling drafting ink from the back side of the coracoid and a hole in the shaft for replenishing ink. In addition, an ink reservoir is provided in the coracoid that can be replenished in an appropriate amount as ink decreases from the coracoid tip, allowing continuous drawing. At the same time as the adjustment screw, the coracoid, which is equipped with a scale device for determining the distance when adjusting the distance between the coracoid tips, is connected to the shaft, or the shaft is removable and can be extended or contracted within the shaft of the coracoid. To provide a coracoid with a hole provided on the back side that accommodates a bendable shape engraving device and compass device.

Next, the present invention will be explained with reference to the drawings.

The attached drawing is a side view of one embodiment of the present invention.
Ink is poured into the hole 3 provided on the back side 2 of the ink so that the ink accumulates so that drawing can be done, and the ink sequentially flows to the tip of the coracoid.

4 is provided with a scale device 5 indicating the distance between the coracoid 1 and the other side 6 (referred to as the coracoid tip) on the other side so as to match the size of the line drawn by the coracoid 1, and a dimension mark 6 provided on the scale device. Further, when the distance between the coracoid tips is adjusted by the distance adjusting device 7, the size can be immediately determined by the dimension 6 of the scale device 5.

Furthermore, the center point needle 9 of the compass is attached to the axis 8 of the coracoid 1.
The opposite side 10, and similarly the tip needle 1 of the compass
1 and the opposite side 12, and has a central shaft 15, the compass is fitted into the groove of the glyph engraving and moved along the groove, so that the axis can be drawn in accordance with the glyph engraving. The tip 14 or the coracoid 1 of 8 is removed from the screwed part 13, and the compass is set to draw or drill a hole, and the center shaft 15 of the compass can be expanded and contracted, and the spacing can be adjusted with the screw. It is a device that can be used to draw circles or measure the spacing between drawn lines.

Furthermore, a compass having an extendable central shaft 15 is housed within the shaft 8, and 16 indicates the place where it is housed. 17 is a screw.

This invention saves the time and effort of refilling the ink by opening the gaps between the coronoids in the middle of the drafting process, and saves the time and effort needed to adjust the spacing to match the lines being drafted, as well as the ink and time needed to make test drawings. You don't have to worry about wasting it, or you don't have to hold many different types of drawing tools like a fountain pen, and you can at least not have to replenish ink for a long time while drawing with a single coronoid, and you only have to adjust the spacing between the coronoids once. Ink is also continuously replenished from the ink reservoir on the shaft through a hole provided on the back side of the coracoid, which prevents it from staining the coracoid or making the thickness of the lines uneven in the drawing. , it was possible to make do with the same coracoid until the drafting was completed, and it was possible to immediately combine both thin and thick lines, and it was also possible to easily draw a circle with a single coracoid using a compass. The effect is truly great.
