Description

[Detailed description of the invention] Technical field This invention solves the problem that is necessary to make incisions with a cutter on the surface of a long flooring material pasted on a subfloor when forming decorative joints on the surface of the long flooring material. Concerning a design joint line drawing tool for drawing parallel lines.

Prior Art Conventionally, a method using tiles has been known as a method of forming decorative (design) joints on a floor surface pasted with synthetic resin flooring, but this method uses tiles of a certain size. As a result of extensive research into methods for creating decorative joints on long flooring materials, the applicant of this application has found that there are limits to the patterns of decorative joints that can be formed, and that it is troublesome to form complex patterns. First, "decorative joint formation method"
(Japanese Unexamined Patent Publication No. 158863, 1983), "Method for forming decorative joints and joint cutting cutter used therein"
102464).

These decorative joints give the floor a marble-like or brick-like finish, and they have a great design effect because they can give the floor a completely different feel even when using the same flooring material. be.

However, in the above-mentioned method, the joints are formed directly on the long flooring material using a cutter, and therefore, there are cases where the cutting depth is insufficient and it is not easy to form the joints with the desired design.

Purpose This invention is used when forming decorative joints on long flooring materials, such as the conventional method described above, and is quick and easy to work with, and forms joints with a constant width and a good finished appearance. The purpose of the present invention is to provide a design joint scribing tool for the design.

Configuration This invention consists of a flat substrate, a plurality of pairs of holes at different intervals that are drilled through the substrate on both sides of the substrate, centered on a line parallel to the side surface of the substrate, and The device is characterized in that it includes a pair of scribing needles that are inserted so that their tips protrude from the bottom surface of the substrate.

This invention will be explained in more detail below based on embodiments shown in the drawings.

In FIGS. 1 and 2, the center of one end of the rectangular substrate 1 is spaced at a certain distance (3 to 7 mm in the embodiment shown in the drawings) centering on a line parallel to each of both side surfaces of the substrate 1. ) are drilled in a plurality of pairs of holes 2 arranged so as to maintain .

Also, a pair of rollers 3 are provided on both sides of the other end of the board 1.
As can be seen from FIG. 2, this roller 3 is rotatably arranged by a leaf spring 4 so that the lower part of the roller 3 slightly protrudes from the bottom surface of the substrate.

Further, a grip portion 5 for operation is attached to the upper surface of the substrate 1.

Incidentally, at the front end and the rear end of the substrate 1, protrusions 6 are formed, each having a step-shaped scale corresponding to the interval between each pair of holes 2.

The above-mentioned scribing tool inserts two scribing needles 7 (Fig. 2) into holes 2 having a desired width for scribing, presses one side of the substrate 1 against a scale (not shown), etc., and follows this scale. The substrate 1 is then moved and used.
As the substrate 1 moves, the tip of the scribing needle 7 accurately draws parallel lines on the surface of the workpiece.

That is, by doing so, two parallel scribing scratches having a depth corresponding to the length of the tip of the scribing needle 7 protruding from the bottom surface of the substrate are made on the surface of the long flooring material. Next, use another cutter to cut the long flooring material along the lines and remove that part to use as the joint. In addition, except for such operations, design joints may be formed by the method disclosed in the above-mentioned application.

At this time, the substrate 1 is smoothly moved by the rollers 3, and the protrusion 6 is
It can be used as a guide before drawing lines.

In other words, when forming designed joints on a long flooring material, two parallel lines are inked on the surface of the long flooring material in advance to create the desired design, and the joints are formed by cutting on these lines with a knife. However, at that time, a line is made with the tool to a desired depth on the line, and then a knife is used to cut from the line to the bottom of the long flooring material (full thickness). Therefore, this lined scratch is formed in order to facilitate subsequent cutting with a knife.At this time, the step-shaped portion of the desired width (same width as the joint width) provided on the protrusion 6 is formed to facilitate subsequent cutting with a knife. If the two scribing needles 7 are aligned with the two inked parallel lines, the two scribing needles 7 will be automatically positioned on the two parallel lines, and the scribing position will be determined. can be easily done.

Further, the scribing needle 7 may be anything with a sharp tip, such as a nail.

Effects As described above, when forming design joints on long flooring material attached to the subfloor, the scribing needle is inserted into the holes at the desired intervals, and the tool is moved along the scale etc. You can easily draw parallel lines of a constant width by simply swiping the lines, making it easy to form design joints with a good finished appearance.You can also change the joint width by simply moving two scribing needles to the desired width. This has an extremely excellent effect, as it is only necessary to replace it with a pair of holes.
