The present invention relates to an elongation and an accumulator that can reduce and enlarge drawings such as forestry, interior, cadastral map, and the like at the same ratio.

Shinto and a pantograph according to the present invention can be reduced and enlarged in the same ratio of map, hallway map, forestry map, cadastral map, blueprint, and similar drawings, but for the sake of clarity of explanation, the elongation and pantograph is illustrative. Will be explained.

The cadastral map is a diagram showing the boundary lines of real estate such as land and forests at a constant reduction ratio, which is a basic data that is useful for forest boundary surveying, forest division, and civil engineering projects.

For example, a survey operation is performed based on the cadastral map during forestry boundary surveying to accurately partition the boundary between the owned land and the neighboring land owned by another person.

In such surveying work, the cadastral map showing the desired survey area is used. However, the cadastral map, which is a duplicate of the original cadastral map, is used because of fear of damage to the original cadastral map.

For reference, referring to the conventional cadastral copying method, after fixing the copying paper at a predetermined position on the plane of the original cadastral map, setting a reference point at a predetermined position of the cadastral map, The intersection point is measured by a ruler, and the reduction point and the enlargement point having the desired reduction and enlargement ratio are displayed on the copy paper on the most straight line where the reference point and the intersection point are connected.

The cadastral map of the replica is completed by connecting the reduced or enlarged points displayed in a straight line.

As described above, the copied cadastral map may be referred to as a reliable cadastral map, but it requires a lot of work time and effort.

Of course, it is also possible to copy the cadastral map using a copier, but the copy copied with the copier does not have value as an cadastral that requires precision because the cadence and deviation of the original are generated. There is a situation.

If various surveys are performed on the wrong or cadastral maps, the survey results can result in significant false survey results, which can lead to various civil and ownership disputes.

Therefore, in order to evaluate the reliability of newly created or reduced and enlarged cadastral maps, the cadastral departments and county cadastral departments must be accompanied by a process of verifying both cadastral and reduced and expanded cadastral maps.

The present invention has been invented to solve all the problems caused during the reduction and enlargement of the cadastral map as described above.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elongate and a pentograph capable of quickly and easily elongation and axle work at a desired reduction and enlargement ratio in duplicating the original cadastral map, forest map, interior view and similar drawings. .

Elongation and shaft adjuster 100 according to the present invention is connected to a plurality of main frame 10 including a plurality of through holes (a to d) in the center in the longitudinal direction in a square shape, each corner is rotatably coupled The front pin 12 is rotatably coupled to one side edge, and a see-through window 16 having a black spot 14 is formed at a center of the diagonally symmetrical edge of the push pin 12, and the main frame Between the main frames 10 facing each other among the 10 of the cross frame 20 designed to have the same size and size as the main frame 10 in parallel with the main frame 10 X-axis Y Coordinate display means is coupled to the through-hole (bd) that is rotatably coupled to the axis and each cross frame 20 coupled to the X-axis Y-axis intersects.

Hereinafter, with reference to the accompanying drawings for the kidney and the pantograph according to the present invention in more detail as follows.

Referring to FIG. 1, FIG. 1 is a perspective view showing an elongation and a pantograph according to the present invention, schematically showing a state of duplicating cadastral maps.

The elongation and the pantograph 100 according to the present invention are all composed of a plurality of main frames 10 having the same shape and shape, and also a cross frame 20 having the same shape and shape as the main frame 10. .

On the surfaces of the main and cross frames 10 and 20, a plurality of through-holes a to d spaced apart at regular intervals are formed in the central portion in the longitudinal direction thereof.

First, as shown in FIG. 2, the plurality of main frames 10 are arranged in a square shape and assembled, and the through holes a of both sides of each of the main frames 10 are aligned, and then bolts and Rotatingly coupled through conventional fastening means such as nuts.

The main frame 10 assembled in a quadrangular shape has a sharp push pin 12 formed on a through hole (a) of one of its corners, and a through hole of the other edge of the diagonal direction of the push pin 12 ( A) is combined with a see-through window 16 having a black spot 14 made of a transparent material.

In addition, a handle 18 for manipulating the main frame 10 is coupled to an edge at which the viewing window 16 is installed.

The above-mentioned thumb pin 12 sets the reference points of the elongation and the accumulator at the time of drawing and drawing the drawing of the cadastral map 30 through the elongation and the accelerometer.

In addition, the see-through window 16 is for visually looking at the boundary line shown in the original cadastral map during the drawing and elongation work, and in order to exactly match the intersection position of the boundary lines of the cadastral map. The black spot 14 is displayed in the center of (16). The see-through window 16 may be manufactured by a magnifying glass, and the black spot may also be displayed by a thin cross line or the like.

The cross frame 20 is positioned between the main frames 10 facing each other among the main frames 10, but the main frame is horizontally parallel to the main frame 10 divided into the X and Y axes. It is selectively rotatably coupled to the plurality of through holes b to d of (10).

As such, each of the cross frames 10 crossing the X-axis and the Y-axis cross-fits the through holes b to d at points where they cross each other, and the respective through holes b to d to be matched. Coordinate display means is coupled to.

As shown in Figs. 3 and 4, the coordinate display means is usually in a state in which an elastic force acts upward on a spring (not shown) with a joining pin 22 at a lower side adjacent to a floor. When a predetermined force is applied downward to the corresponding side of the pressing pin 22, the end of the pressing pin 22 is duplicated to form a pressure point on the surface of the vaginal paper 40. At this time, the coordinate display means is always located on the diagonal of the main frame 10, the push pin 12 and the viewing window 16 is formed.

In addition, the coordinate display means can expect the same effect even if using a sharp black core of a writing instrument such as a pencil in place of the pressure pin (22).

When described in detail with reference to the accompanying drawings, the working example and the working effect for the elongation and pantograph according to the present invention configured as described above.

First, when the cadastral map is to be scaled through the elongation and the pennant according to the present invention, as shown in FIG. The elongation and the phonograph are placed on the original cadastral map 30 and the push pin 12 of the elongation and the phonograph 10 is inserted at a predetermined position of the cadastral map 30 to set a reference point. The reference point may be any point of cadastral map, and is only a reference point in the operation of the elongation and the pantograph.

As described above, the intersection of the boundary lines shown in the cadastral map is visually seen through the viewing window 16 through the elongation and the pantograph 100 in which the reference point is set, and the black frame 14 is vertically aligned with the intersection point of the boundary line. Pressure points are formed on the surface of the sheet of paper 40 to be rolled down by pressing the coordinate display means provided in the matched through holes b to d below.

By connecting the pressure points formed by repeating the above operations with writing instruments, the cadastral map reduced in the same ratio as that of the cadastral map 30 can be created.

The ratio of the axial degree is changed according to the state in which the through-hole formed on the cross frame 20 is located on the diagonal of the main frame 10 in the axial ratio of the reduced cadastral degree. In other words, as the coordinate display means moves away from the push pin 12 toward the see-through hole 16, the drawing is larger, and the closer to the front pin 12, the smaller the drawing.

On the contrary, in the case of the cadastral drawing, when the installation position of the above-described viewing window 16 and the coordinate display means are interchanged and installed, the elongation and the scaler are operated in the same manner as the aforementioned axial drawing method, and the cadastral map enlarged at a constant ratio is obtained. I can write it. At this time, the coordinate display means, the greater the distance to the viewing window 16, the larger the enlargement ratio, the shorter the accuracy ratio is relatively small.

As described above, the elongation and shaft drawing machine according to the present invention can easily and quickly perform drawing and drawing work at the same ratio as the original cadence, and can eliminate artificial errors. The cadastral map, forest field diagram, interior view and similar drawings can be produced.
