Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawing device for easily creating a plan view from a three-dimensional object, and in particular, to simplify the plan view of a line diagram, figure, picture, etc. on a three-dimensional object. This is related to the device described in FIG.

[Prior art and its problems]

Conventionally, when drawing a plan view from a three-dimensional object, measure the main points with a divider etc., draw as a series of points on graph paper,
At that point, each point was connected to create a plan view.

From these three-dimensional objects, plan views, side views, rear views, etc. are drawn only when drawing production drawings from real objects, or when drawing earthenware, haniwa, teacups etc. excavated from archeological sites. This is required when drawing a flat view.

Conventionally, drawing a floor plan based on an excavated product from an archeological site required five days to one week. In particular, it is necessary to transcribe the pictures and patterns displayed on the surface of the pottery etc.
It required skill and days. Further, in order to easily make accurate copies of these excavated items, photographic recording has been attempted.

However, since a photograph uses a lens, a part that should not be seen originally can be seen due to distortion peculiar to the lens and light wrapping around the contour part, and accurate recording cannot be performed.

Furthermore, a device for creating a plan view from a three-dimensional object by a complicated mechanism has been proposed, but it is complicated, requires skill, is expensive, and is far from widely used.

[Means for solving the problem]

An object of the present invention is to provide a drawing apparatus capable of accurately creating a plan view from a three-dimensional object with a simple structure, in order to solve the above conventional problems, and a drawing board,
A moving frame that translates only on the drawing board plane in the Y direction;
A vertically extending member that can move in a parallel manner only in the X direction on the drawing board plane in an elongated hole formed in the moving frame, and a workpiece support table that is vertically suspended on the drawing board; An object to be measured fixed to the object support table is measured with a measuring needle suspended vertically at the tip of the hanging member, and is placed on a drawing board with a writing implement provided at a base end of the hanging member. On a sheet of paper, and draws a three-dimensional plan view of the object to be measured.

(Example of the invention)

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view of a drawing apparatus showing one embodiment of the present invention, FIG. 2 is a side view showing a hanging member, and FIG. 3 is a plan view showing a hanging member.

In the drawing, reference numeral 1 denotes a drawing board, and rail members 2 parallel to both ends are fixed by screws 3. Reference numeral 4 denotes a moving frame which is placed between the rail members 2 and 2 in the Y direction (first direction).
It is provided so as to be able to move in parallel in the vertical direction in the figure. The moving frame 4 has a rectangular long hole 4a formed therein.
The hanging member 5 is loosely fitted therein so as to be able to move in parallel in the X direction.

FIG. 2 is a side view showing the hanging member 5. The hanging member 5 is a square, a board 5a that moves in parallel in the elongated hole 4a provided in the moving frame 4, a part A (5b) erected on one end side of the board 5a, and the part A (5b). B fixed with fixing screws 7 so that it can move vertically in the long groove 6 drilled in
(5c) and a part C (5d) fixed to a long groove 8 formed in the part B (5c) by a fixing screw 9 so as to be movable in a horizontal direction.
And a part D (5e) suspended from the tip of the part C (5d) by a fixing screw 10 and a pipe 11 fixed to the part D (5e).
It is composed of a measuring needle 13 supported by a thread 12 so as to be able to move in the vertical direction, a writing instrument 14 fixed to the end of the part A (5b), and the like. In addition, a weight 15 is provided on the measuring needle 13 so that the measuring needle 13 can be easily lowered. Measuring needle 13
The thread 12 that supports the hole is a hole drilled at the upper end of the part D (5e).
The part A (5b) passes through a hole 17 formed in the upper end of the part A (5b), and is locked to a lever member 19 supported by a fixing screw 18 so as to be able to rotate halfway on the part A (5b). Therefore, by operating the lever member 19 in the direction of arrow A, the measuring needle 13 at the tip can be moved up and down.

As shown in FIG. 1, an object support table 20 is fixed substantially at the center of the front of the drawing board 1, and the object support table 20 has a three-dimensional portion for which a plan view is to be created, for example, Excavated earthenware is fixed. Here, the part B (5c) and the part C (5d) can be moved in parallel along the long grooves 6, 8, respectively. For this reason, the position of the tip of the measuring needle 13 can be adjusted by loosening the fixing screws 7, 10 in accordance with the size and height of the object to be measured and sliding in the long groove.
Furthermore, if the fixing is performed between the fixing screw 7 and the part B (5c) via the rubber packing 21, the fixing of each part can be performed more reliably.

The writing implement 14 fixed to the end of the part A (5b) has a hole 14a at substantially the center, and a pencil lead 14b is inserted into the hole 14a, and the head of the pencil lead 14b is lightly pressed. Thus, marking can be performed on a sheet of paper such as graph paper placed on the drawing board 1. Further, the tip of the measuring needle 13 can be freely moved up and down by rotating the lever member 19 around the fixing screw 18.

A method of using the drawing apparatus of the present invention configured as described above will be described with reference to FIG. First, the object support
Fix the solid for which you want to draw a floor plan at 20. Then, the graph paper is fixed to the movable range of the hanging member 5 on the drawing board 1.
Next, parts B (5c) and C (5d) are adjusted by loosening the fixing screws 7, 9 so that the tip of the measuring needle 13 can move freely at each measurement point of the three-dimensional object. Fine adjustment of the tip of the measuring needle 13 after fixing the positions of the parts B (5c) and C (5d) according to the size of the three-dimensional object is performed by operating the lever member 19.

Now, operate the lever member 19 to the measurement point of the three-dimensional object and
After the tip of 13 is dropped and the position of the hanging member 5 is determined, the pencil lead 14b of the writing implement 14 is lightly pushed to mark the graph paper on the drawing board 1. The moving frame 4 and the hanging member 5 are sequentially moved to X
After marking the measurement points of the three-dimensional object by moving in the direction and the Y direction, and connecting the points on the graph paper, an accurate plan view of the three-dimensional object can be drawn. In this way, according to the plotting device of the present invention, when drawing an accurate plan view of an excavated product from an archeological site, it took two to three hours to take one individual, five days to one week. In the required time.

Moreover, since the operation is simple, even a beginner can easily use it without any skill.

Incidentally, the drawing apparatus of the present invention is not limited to the above embodiment, and it is needless to say that various design changes can be made based on the technical idea of the present invention.

Furthermore, if the writing implement is marked in conjunction with the operation of the lever member 19, the working efficiency can be further improved.

Although the material of the present invention is not particularly described, a synthetic resin, a light alloy, for example, aluminum or the like can be optimally used.

〔The invention's effect〕

As described above in detail, according to the drawing apparatus of the present invention, a plan view can be easily drawn from a three-dimensional object with a simple structure. Therefore, the number of days required for drawing can be significantly reduced. In addition, the plotting device of the present invention, when operating,
Anyone can easily operate and draw without skill.

Furthermore, since it has a simple structure, it can be provided at extremely low cost as compared with the related art.
