Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a drafting article such as a ruler, a protractor, or a template, and particularly to a drafting article having a plate shape.

[0002]

[Prior art]

 Most conventional rulers, protractors, etc. are made of plastic and have a smooth surface, which makes them slippery. Therefore, there is a problem that a ruler or the like is easily moved during use and is not stable. There is also the problem of slipping and loss when not in use.

[0003]

[Problems to be solved by the device]

 Therefore, the present invention solves the above-mentioned problem, that is, it can prevent unintentional movement during use and stabilize it, and can prevent loss when not in use. The challenge is to provide drafting supplies.

[0004]

[Means for Solving the Problems]

 The ruler and protractor of the present invention devised to solve the above problems are provided with a recess on one or both sides of a plate member, and a magnet is fitted into the recess to attach the magnet to the plate. The structure is characterized in that the surfaces of the members are substantially flush.

[0005]

【Example】

 Hereinafter, the illustrated embodiment of the present invention will be described. First, FIGS. 1 to 3 show a straight line ruler 1 of the first embodiment. In this straight line ruler 1, recesses 3 and 4 are provided at both ends of one surface of a long transparent plate member 2 made of plastic, and disk-shaped magnets 5 and 6 are fitted into the recesses 3 and 4, respectively. The magnets 5 and 6 and the plate member 2 are fixed to each other by means such as adhesion so that the surfaces thereof are substantially flush with each other.

Next, FIG. 4 shows a linear ruler 7 of the second embodiment. This straight line ruler 7 has a long transparent plastic plate-like member 8 having a recess 9 extending in the longitudinal direction of the plate-like member 8 at approximately the center on one side thereof. Is fitted and fixed by means such as adhesion, and the surfaces of the magnet 10 and the plate member 8 are made substantially flush with each other.

Next, FIG. 5 shows a triangular ruler 11 according to a third embodiment. This triangular ruler 11 is provided with recesses 13, 14 and 15 at three corners on one side of a transparent plastic plate-like member 12, and the recesses 13, 14 and 15 are disc-shaped respectively. The magnets 16, 17 and 18 are fitted and fixed by means such as adhesion, and the surfaces of the magnets 16, 17 and 18 and the plate member 12 are made substantially flush with each other.

Next, FIG. 6 shows a protractor 19 of the fourth embodiment. This protractor 19 is provided with recesses 21 and 22 at two positions on the left and right of one surface of a transparent plastic plate member 20, and the disk-shaped magnets 23 and 24 are fitted into these recesses 21 and 22, respectively. The surfaces of the magnets 23 and 24 and the plate member 20 are made substantially flush with each other by fixing them by means such as adhesion.

Although each of the above embodiments relates to the straight line rulers 1 and 7, the triangle ruler 11, and the protractor 19, the present invention is not limited to these, and other rulers or templates may be used. It is feasible.

Further, in each of the above embodiments, the magnet is attached only to one side of the plate-shaped member, but it is also possible to provide the magnet on both sides of the plate-shaped member.

Further, the magnet used in each of the above-mentioned embodiments has a disk shape or an elongated plate shape, but the shape of the magnet is not limited to these and may be any shape. In addition to ordinary magnets, magnets made by mixing magnetic materials into plastic or rubber can also be used.

[0012]

[Effect of the invention]

 The ruler, protractor, and other drafting supplies of the present invention are as described above, and when used on a steel desk, etc., the plate member is attracted and fixed to the desk surface by the action of the magnet. It is possible to obtain the effect that the position is stable and the drawing work is easy to perform without unintentionally moving involuntarily. Also, it can be prevented from slipping and being lost even if it is left on the desk when not in use.
