BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for drawing a cut line along a curved line of a table, particularly when a surface decorative plate such as a curved table is cut into the contour shape of the table.

[0002]

2. Description of the Related Art Conventionally, when cutting a veneer of a curved table, the veneer is placed on the table, the curve of the table is trimmed from below with a writing instrument, then the veneer is turned over and drawn on the back. Cut it along the line, turn it over again, and attach it at the same position on the table, stick it, or fix it by nailing.

[0003]

[Problems to be Solved by the Invention] With the conventional method,
It is troublesome and time-consuming to draw the cutting line from below, it is difficult to work, and the veneer has to be turned over twice, and it is very careful to align the veneer in its original position. It was laborious, laborious and time consuming.

SUMMARY OF THE INVENTION Therefore, the present invention provides a mapping device capable of drawing a contour of a table on a decorative plate without removing the decorative plate.

For this purpose, two parallel upper and lower arms are arranged with a space therebetween, and an adjustable arm is provided between the upper and lower arms so as to be orthogonal to the respective arms, and the upper and lower arms and the adjustment arm are arranged. The adjustment arm is slidably fixed to the upper and lower arms, the writing tool is formed at the tip of the upper arm, and the rotating feeler fixing portion is formed at the tip of the lower arm.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings.

An upper arm 1 and a lower arm 2 are arranged in parallel and at a distance, and an adjusting arm 3 is provided between the upper and lower arms 1 and 2 which are parallel to each other. 3 is telescopically expandable, and the adjusting arm 3 is fixed to the upper and lower arms 1 and 2 so as to be slidable along the upper and lower arms 1 and 2.
One end of the upper arm 1 is a fixed part of a writing instrument 4 such as a pencil, and a feeler 5 rotating like a roller is attached to the end of the lower arm in the same direction so as to have a parallel axis with the adjusting arm 3. There is.

Reference numerals 6, 7, and 8 are fixing screws for stopping the movement of each part. When using the picture-taking device of the present invention, as shown in FIG. 2, a decorative plate 10 made of stone or the like is placed on a table 9, and appropriate portions are fixed with clamps 11 and the like. Contact the curved surface of the table 9 and adjust the expansion and contraction of the adjustment arm 7 to adjust the writing instrument 4 up and down so that the writing tool 4 abuts on the decorative plate 10, and then the feeler 5 rolls along the curved surface of the table. The writing instrument 4 draws the same contour as the table on the decorative plate. The upper and lower arms 1 and 2 of the mapper A are
The coupling position of the adjusting arm 7 is slid in the opposite direction so that the writing instrument 4 and the feeler 5 are extended in accordance with the extension length of the decorative plate 10 with respect to the table 9. Also, the writing instrument 4 and the peripheral surface of the feeler 5 are adjusted so as to be positioned on the same vertical line.

[0009]

According to the present invention, since the cut line can be drawn on the decorative plate by rolling the feeler along the curved surface of the table, the table curve can be traced from below as in the conventional case, and then the decorative plate can be turned upside down. The veneer can be easily cut without the trouble and time required for cutting and then accurately realigning it inside out again.

Claims (1)

(57) [Scope of utility model registration request] 1. An adjustment arm, which is fixed between two parallel upper and lower arms at a right angle and is slidable with respect to both arms, and is itself expandable and contractable, is extended between both arms. A pattern mapper in which the tip of the arm in one direction is the fixed part of the writing instrument, and a rotating feeler is fixed to the tip of the lower arm in the same direction.
