Description

The present invention relates to a drawing tool, and particularly to a large drawing tool for drawing a straight line over a long distance.

Conventionally, there is a ink brush as a representative drawing tool, which is used as a tool for easily drawing a long straight line on the surface of a material such as wood during construction.
In addition, there is a chalk drawing tool that draws a straight line by the same method as the ink brush, which draws a straight line using chalk powder that is easy to handle instead of ink and ink used for ink. In the choke drawing tool, a reel wound with a thread for drawing a straight line is rotatably supported on a shaft or the like standing in the case, and the thread wound around the reel contains chalk powder. It passes through the chalk chamber and is guided to the outside of the case.

In the drawing work (marking work) by this choke drawing tool, a case is placed at one end of the drawing range, and a hook (karuko) tied to a thread locked at a yarn entry / exit of the case is pulled out. By this drawing, when the yarn passes through the chalk chamber, the chalk powder adheres to the yarn and comes out of the case.
Then, the hook is placed on the other side of the drawing range, the yarn is stretched, the yarn is struck against the drawn surface by releasing the yarn upward, and the chalk powder adhering to the yarn is removed from the drawn surface. A straight line can be drawn by adhering to

When the drawing operation is finished, the handle provided in the case is rotated in the yarn winding direction, whereby the drawn yarn is wound on the reel in the case.
The reel and the handle are connected via a shaft that transmits rotation. Usually, the reel is arranged in the case, and the handle is arranged outside the case. The reel may be isolated from other members in the case. That is, a chamber for storing the reel is provided in the case, and the chamber is arranged in the chamber.

  The drawing tools are as described above. However, the drawing tools used on roads and parking lots, that is, relatively large drawing tools for drawing straight lines over long distances, are limited to those who use them. It is provided without any improvement as it was originally released. From this, the present applicant verified the handling property of a conventional wire drawing tool in order to provide a wire drawing tool having higher performance, that is, excellent handling property. As a result, the following problems were found.

It is necessary to fill the case of the wire drawing tool with the chalk powder while holding the wire drawing device with one hand, and it is very difficult to fill the chalk powder.
Also, in drawing work, when drawing many long straight lines, the work must be done while winding the drawn-out yarn again in the case and attaching the chalk powder to the yarn every time several draws are completed. I must. In addition, if there is a portion where the chalk powder did not adhere to the yarn, the yarn must be wound up in the case again to attach the chalk powder, and the drawing work cannot be performed smoothly, which takes time. .
Furthermore, in changing the drawing color, the chalk powder already filled in the case must be taken out from the case, and the chalk powder of a new color must be filled in the case. At this time, storage of the extracted chalk powder, spilling of the chalk powder at the time of extraction, and depending on the humidity state of the chalk powder, it may take time to take out, or depending on the color to be changed, the chalk powder remaining in the case The drawing work performed by changing the drawing color is time-consuming and time-consuming.

Therefore, the present invention has been made in view of the above-described problems, and can easily and easily set the chalk powder on the drawing tool, and can smoothly perform the drawing work. It is another object of the present invention to provide a drawing tool capable of easily and quickly changing the drawing color.

  The gist of the present invention is that a reel around which a yarn is wound is rotatably provided in a case, and the yarn wound around the reel passes through a tank portion that contains an arbitrary coloring member for marking. The drawing tool guided to the outside of the case is characterized in that the tank portion can be attached to and detached from the case main body while the yarn is allowed to pass therethrough.

The wire drawing tool of the present invention will be described in detail. The case is a member that houses at least a reel for winding a wire for drawing and a housing portion for a coloring member for marking, and is also a main body of the wire drawing device.
The case is a combination of semi-cases made of ordinary resin material, metal material, etc., and a case assembly formed by arbitrarily dividing the case. And the reel which winds the thread | yarn for wire drawing in the case is rotatably provided.

Then, the position of the connecting means is set to a position at which connection or release operation can be performed from outside the case body when all the yarn wound around the reel is fed out and the tank portion is removed.

Furthermore, an accommodation unit that can accommodate an arbitrary length of the thread that has been disconnected from the reel may be provided. The accommodation of the yarn may be the entire length of the yarn or only an appropriate length of yarn, and may be determined according to the adapting form of the drawing tool.
The form and accommodation method of the accommodation means are not particularly limited as long as the accommodation means can be accommodated so as not to cause entanglement of the yarn. For example, the yarn may be stored in a wound state by a winding mechanism such as a reel, or the winding mechanism such as a reel may be driven by power supply using an arbitrary battery as a drive source. Of course, the thread may be wound up by manually rotating the handle or the like.
The storage means may be provided integrally (internal / external) with the tank part, or may be provided independently as a separate member from the tank part. When it is provided as a separate member from the tank part, it may be attached to the tank part by any engaging means. Of course, you may make it handle independently as a thread | yarn accommodating member, without enabling it to attach to a tank part.

  Then, an accommodation member formed separately from the wire drawing tool may be provided, and the accommodation member may accommodate the thread from which the tank part removed from the case body and the reel are released. Further, the accommodation form and accommodation method are not particularly limited as long as the yarn can be accommodated so that the yarn is not entangled. For example, the yarn may be stored in a wound state by a winding mechanism such as a reel, or the winding mechanism such as a reel may be driven by a power source drive using an arbitrary battery as a drive source. Of course, the yarn may be wound up by manually rotating the handle or the like.

In addition, the tank part can be removed from the case body, and the connection between the thread and the reel can also be released, so when changing the drawing color, the tank part is removed from the case body and the connection between the thread and the reel is released. Remove the tank and thread from the wire drawing tool, attach the tank part where the desired colored chalk powder and wire are set to the wire drawing tool, that is, connect the thread to the reel and place the tank in the case. The drawing color can be changed by attaching to the main body.

  Since the drawing tool of the present invention is configured as described above, the drawing tool can be stably supported when the drawing tool is filled with chalk powder. In addition, when removing the tank part from the drawing tool body and filling it with chalk powder, the light weight applied to the hand is reduced because the hand-held member is only a light tank part, and it is stable even during the filling of the chalk powder. Thus, the tank part can be held. Moreover, the charging port (opening) of the chalk powder in the tank portion can be widened, and the chalk powder can be charged without spilling.

  Also, when the chalk powder does not adhere to the yarn during drawing, the tank part is removed from the case body, and only the tank part is moved to the place where the chalk powder has not adhered to the yarn. Therefore, it is not necessary to perform the troublesome operation of winding the yarn again into the case and drawing it out to attach the chalk powder as in the prior art.

Furthermore, when changing the drawing color during drawing work, the tank part can be removed from the case body and the thread can also be disconnected from the reel. Because the drawing color can be changed by attaching the tank part filled with chalk powder and the tank part where the drawing thread is set to the drawing tool, even during drawing work The drawing color can be changed easily and speedily.
