JP2006231889A - Drafting board fitted with straightedge having paper holding channel - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a drafting board which can be simply used by anyone in taking into consideration that commercially available drafting boards are expensive and complicate to operate even though there are many persons who have needs for drawing simple drawings. <P>SOLUTION: A straightedge having a paper holding channel is fitted on the lower end of the drafting board, and the lower end of a paper is inserted therein, and the paper is freely removably fixed by a banker clip or a magnet tape. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

    The present invention relates to a structure of a drawing board.

    There are many types, from a drawing board equipped with a drawing machine with advanced functions to a drawing board with a simple structure. There are drafting boards having a simple structure such as utility model 3008866, Japanese Patent Laid-Open No. 08-2180, Japanese Patent Laid-Open No. 2000-309192, and Japanese Utility Model Laid-Open No. 6-7992.

Problems to be solved by the invention

    There are many people who need to draw simple drawings at home. Commercial drawing boards are expensive and complex to operate. I wanted a drawing board that anyone could use easily.

Means to solve the problem

    A plurality of clip insertion holes 4 are made in a substrate 3 such as a plywood. The top plate 1 made of melamine resin or thin steel plate is stretched. A paper holding groove 5 is formed on a linear ruler 2 such as aluminum and attached to the lower end of a bunker clip drawing board 6.

    A magnet sheet 7 is attached to a substrate 3 such as a plywood. A paper holding groove 5 is formed on the straight ruler 2 and attached to the lower end of the magnet drawing board 8.

Embodiment of the Invention

    An embodiment of the invention will be described based on an example with reference to the drawings.

FIG. 8 An example of the bunker clip drawing board 6. The paper 11 is inserted into the paper holding groove 5 of the linear ruler 2. The bunker clip 9 is inserted into the clip insertion hole 4 to fix the paper. Match the T-shaped gap ruler 10 (Japanese Patent Application No. 2004-052460) with the straight line ruler 2. The T-shaped gap ruler 10 is slid on the linear ruler 2 and set at an arbitrary position. The stock price chart is drawn by moving the slide 18 up and down.

FIG. 9 shows an example of the magnet drawing board 8. The paper 11 is inserted into the paper holding groove 5 of the linear ruler 2. Fix with magnetic tape 12. The T-type gap ruler 10 is aligned with the straight line ruler 2. The T-type gap ruler 10 is slid on the linear ruler 2 and set at an arbitrary position. A vertical line 13 is drawn.

FIG. 10 The T-type gap ruler 10 is used from the state of FIG. Draw in the same way as a normal drafting T-type ruler. The T-shaped gap ruler 1010 is slid on the outer periphery of the drawing board 8 to draw a horizontal line at an arbitrary position.

11 and 12 are detailed views of the T-shaped gap ruler 10 (Japanese Patent Application No. 2004-052460).

FIG. 13 is a rear perspective view of the T-shaped gap ruler 10 (Japanese Patent Application No. 2004-052460). Use in the same way as a normal T-type ruler.

Utility of the invention

The paper can be fixed and removed quickly and freely, and the positioning of the paper is accurate.

The straight line ruler 2 is a drawing standard and is drawn in cooperation with a T-type gap ruler or a triangle ruler.

The paper is not damaged because the paper is fixed with a bunker clip or magnetic tape.

A stock price chart can be easily drawn in cooperation with a T-shaped gap ruler (Japanese Patent Application No. 2004-052460). The T-type gap ruler 10 can be used in two ways on the front and back sides.

Because it is easy to handle, it can be expected to be used as an easy-to-use drawing board at home and school.
