[Industrial applications]

 The present invention relates to a scale corresponding to an arbitrary scale, which is used when reading a dimension of a drawing which is reduced to an arbitrary magnification and enlarged.

[0002]

[Prior art]

 In general, various design drawings for buildings, large machines, etc. are drawn with actual dimensions reduced to 1/100, 1/200, 1/500, etc. so that they can fit on a sheet of a predetermined size. For this reason, in the above design drawing, when reading the dimensions at locations where no dimensions are shown in the figure, in addition to the scales of the standard dimensions, multiple scales of reduced scales such as 1/200 and 1/500 are used. Various types of scales such as the provided triangular scale are used. However, with the development of copying machines in recent years, drawings originally drawn at a fixed scale ratio are enlarged and reduced by the above copying machines, so that they can be displayed at an arbitrary scale ratio different from the original scale instructions of the drawings. There are many opportunities to use scaled drawings. When you want to read the size of the part where the dimension is not written in the drawing that has been reduced to an arbitrary scale, first read the length of the dimension display part in the figure with the scale of the reference dimension, and then read it. After calculating the scale ratio in the drawing, it is necessary to read the size of the part without the dimension display on the scale of the standard size and calculate the original actual size from this and the above scale ratio. There was a problem that it took time and effort.

Therefore, as a conventional scale for solving such a problem, the one proposed in Japanese Utility Model Laid-Open No. 61-163902 is known. 7 to 9 show a conventional scale corresponding to an arbitrary scale, which is formed in a transparent substrate 1 and one side of the triangle is set as a reference line 2 and the reference line 2 is shown in FIGS. Scales 3 are provided at equal intervals and dimension numbers 4 and 5 are engraved. Radiation 7 is formed on the scale 3 around the apex 6 facing the reference line 2 and parallel to the reference line 2. A large number of scale lines 8 are formed, and scale numbers 9 are engraved on each scale line 8. As shown in FIG. 8, if it is desired to read an unknown a-b dimension, first display in the figure. After aligning a line segment a-c with a dimension (5.00 m) with the reference line 2, scale the auxiliary scale D until the point c coincides with the radiation 7 of the displayed dimension, as shown in FIG. Translate along with and read ".8" in scale number 9 on scale line 8. Then, by aligning the line segment ab with the scale line 8 on the scale number 9 ".8" and reading the dimension number on the reference line 2 to which the radiation 7 at the point b is connected, The -b dimension is read.

[0004]

[Problems to be solved by the device]

 However, in the conventional scale corresponding to the arbitrary scale, since the lower dimension portion is read through the transparent substrate 1, the transparent substrate is moved as the dimension portion to be read is moved to the apex 6 side. There is a problem that the radiation 7 and the scaled line 8 on 1 and the lines in the drawing interfere with each other, which makes it difficult to read the dimension portion in the drawing. Moreover, since the line connecting the scale 0 and the apex 6 is an oblique line, a separate auxiliary scale D is required when the display dimension line is aligned with the scale line 8, and therefore two scales are required for reading. It also had the drawback of being cumbersome to handle. In addition, as a result of the whole being in the form of a triangle, the scales 4 and 5 also move in the horizontal direction as the scale moves up and down, so when using the auxiliary scale D, the scale and auxiliary scale D are If it is not slid tightly, the radiation 7 on the 0 scale side and the point a will not match, and the above work will be repeated again, and there is a problem that the overall usability is poor.

The present invention has been made in order to effectively solve the problems of the conventional scales corresponding to arbitrary scales, is easy to handle, and can easily read the dimensions in a drawing scaled / enlarged to an arbitrary scale. The purpose is to provide a scale corresponding to any scale.

[0010]

[Action]

 In the scale according to any one of claims 1 to 6, since the scale is composed of a bendable sheet-shaped member, when reading an unknown dimension in the drawing, the scale corresponding to the arbitrary scale is first performed. While bending itself properly, move one end of the display dimension part in the drawing along the line connecting the scales 0 and align the other end with the scale connecting line of the size that matches the display dimension. Fold the scale along the scale lines. As a result, the folding edge becomes a scale scale corresponding to the scale factor of this drawing, and thereafter, this folding edge is aligned with the unknown dimension part in the same manner as a normal scale scale, and the scale where the end is located. By reading the scale on the connecting line, the actual size of the unknown size portion can be obtained.

Further, according to the scale corresponding to any scale of claim 2, first, the display dimension in the drawing is positioned at the edge of the pedestal, one end of the scale is aligned with the 0 scale of the scale, and the other end is read. Align with the gauge and then rotate the roll to bring the other end of the indicated dimension through the reading gauge to the graduation line of the corresponding dimension of the scale on the roll. As a result, the scale lines that intersect the scale connecting line become the scale factor of the drawing. Therefore, from this state, align the edge of the pedestal with an unknown dimension in the drawing, align one end with the 0 scale of the scale, move the reading gauge in the axial direction of the roll-shaped member, and move it to the other end. After the adjustment, the reading gauge reads the scale on the scale connecting line intersecting with the scale scale line to obtain the actual size of the unknown size portion.

Further, when reading an unknown dimension in the drawing by the scale corresponding to the arbitrary scale according to claim 3, first, the display dimension in the drawing is positioned in the window portion of the case, and one end thereof is set to 0 scale of the scale. At the same time, the drum is rotated by the rotating means to move the scale wound endlessly so that the other end of the above-mentioned display size is aligned with the scale connecting line of the corresponding size of the scale. As a result, the scale line that intersects the scale connecting line becomes the scale factor of the drawing. Therefore, from this state, align the window of the case with an unknown dimension, align one end with the 0 scale of the scale, and read the scale of the scale connecting line on the scale scale where the other end is located. The actual size of the unknown size part can be obtained.

Here, in the invention according to claim 2 or 3, as in the invention according to claim 4, the line connecting the scale 0 at the standard size of the scale and the scale 0 at the 1 / n size is If you make it so that it is orthogonal to the upper and lower reference lines, the 0 scale position on the scale will not move to the left or right even if you rotate the roll-shaped member or drum. In accordance with the above, by rotating the roll-shaped member or the like, the other end can be easily aligned with the scale connecting line, and thus it is not necessary to use a separate auxiliary scale unlike the conventional one.

[0014]

[Embodiment 1] FIG. 1 shows a first embodiment of a scale corresponding to an arbitrary scale according to the present invention, in which reference numeral 10 is a reference line drawn on the lower stage of a bendable sheet-shaped member. . The reference line 10 is engraved with a scale 11 having a standard size such that the end portion on the left side of the drawing is 0. The standard size scale 11 is a scale of a normal Cm ruler displayed in mm. This corresponds to a scale of m units in the drawing with a scale of 1/100. Further, a reference line 12 is drawn parallel to the reference line 10 on the upper end of the sheet, and the reference line 12 is further 1/10 of the reference dimension (that is, 1/1000 in m unit). A scale 13 having a reduced scale is engraved. Here, the scale 0 of the reference line 12 is engraved so as to be located at a position opposite to the scale 0 of the reference size in the lower stage and in the direction perpendicular to the reference lines 10 and 12.

Between these reference lines 10 and 12, graduation connecting lines 14 connecting the respective scales 11 in the lower stage and the corresponding scales 13 in the upper stage are engraved, and further these reference lines 10 and 12 are connected. A plurality of scale lines 15 are drawn in parallel. Further, on the right side of the scale lines 15 in the figure, the scale factors 16 for m units of the scale connecting line 14 on each scale line 15 are displayed.

When it is desired to read the unknown dimension in the drawing with the scale corresponding to the arbitrary scale configured as described above, first, one end A of the line segment AB in which the dimension 10 m is displayed in the drawing is set to the scale 0. While arranging on the line connecting each other, gradually bending the arbitrary scale scale itself, aligning the other end B with the scale connecting line 14 connecting the dimension 10 m, and at this position as shown by the dotted line 17 in the figure. Then, fold the scale parallel to the scale line 15. As a result, the edge portion bent along the dotted line 17 becomes a scale scale corresponding to the scale factor of this drawing, and thereafter, this folding edge portion is made into a scale similar to a normal scale scale, and its 0 scale is set to an unknown dimension. The actual size of the unknown size part can be obtained by reading the scale of the connecting line 14 on the dotted line 17 in which the other end is located in alignment with one end of the part.

Therefore, in the scale corresponding to the arbitrary scale, when aligning the other end B of the line segment AB with the scale connecting line 14 that matches the display size 10 m, the line connecting the scale 0 in the upper and lower rows is Since it is orthogonal to the reference lines 10 and 12, it is only necessary to move the scale vertically by aligning this line with one end A of the line segment A-B, so an auxiliary scale or the like is required like the conventional one. Therefore, it is easy to handle. Moreover, once the scale factor of the drawing is obtained from the line segment AB and the scale is bent, the folded edge can be handled in the same manner as a normal scale, so that it is extremely easy to see in the drawing. The actual size of the unknown size part of can be read.

[0018]

Second Embodiment FIG. 2 and FIG. 3 show a second embodiment of the scale corresponding to an arbitrary scale of the present invention, and the same components as those shown in FIG. The description is omitted. In FIGS. 2 and 3, a scale corresponding to an arbitrary scale of this example is a roll (roll scale) in which a scale 20 is formed by engraving a scale similar to the scale in the first embodiment on a flexible sheet member. (Shaped member) 21 is attached to the outer peripheral surface of the roll 21 such that its axis and the reference lines 10 and 12 are parallel to each other, and the roll 21 is rotatably provided on the pedestal 22. A reading gauge 23 is provided on the outer periphery so as to be movable in the axial direction. The reading gauge 23 is for reading the scale on the scale 20 from the size of the edge portion 22a of the pedestal 22, and has a ring-shaped portion 24 slidably fitted in the circumferential direction of the roll 21. A pointer portion 25 extending from the lower end of the ring-shaped portion 24 onto the edge portion 22a of the pedestal 22 and a scale reading that extends horizontally in parallel with the scale graduation line 15 in the reading portion 26 at the middle position of the ring-shaped portion 24. It is formed with the taking part 27.

When reading the unknown dimension in the drawing with the scale corresponding to the arbitrary scale configured as described above, first, the line segment A-B in which the dimension in the drawing is displayed is positioned on the edge portion 22a of the pedestal 22. The one end A is aligned with the 0 scale of the scale 20, and the other end B is aligned with the pointer portion 25 of the reading gauge 23. Then, the roll 21 is rotated so that the reading portion 26 of the reading gauge 23 and the scale connecting line 14 corresponding to the display size in the drawing on the scale 20 are aligned with each other. Then, the scale reading at this time is read by the scale reading unit 27. Next, from the state where the scale reading unit 27 is in the scale magnification position, the edge 22a of the pedestal 22 is aligned with an unknown dimension portion, one end thereof is aligned with the 0 scale of the scale, and the pointer of the reading gauge 23 is set. After moving the portion 25 in the axial direction of the roll 21 to align it with the other end, by reading the scale on the scale connecting line 14 in the reading portion 26 of the reading gauge 23, the actual dimension of the unknown dimension portion is obtained. be able to.

According to the scale corresponding to the arbitrary scale, the scale magnification of the drawing can be read only by rotating the roll 21, so that an auxiliary scale or the like is not required unlike the conventional one, and thus the handling is easy. is there. At this time, since the line connecting the scale 0 in the upper and lower stages of the scale 20 is orthogonal to the reference lines 10 and 12, even if the roll 21 is rotated by aligning this line with the one end A of the line segment AB. Since the one end A and the scale 0 do not shift in the left-right direction, the reading can be performed more easily. Moreover, once the scale magnification is read, the edge portion 22a of the pedestal 22 can be handled in the same manner as a normal scale, and therefore, as in the first embodiment, it is extremely easy to find the unknown in the drawing. The actual size of the size part can be read.

[0021]

Third Embodiment FIGS. 4 to 6 show a third embodiment of the present invention. Similarly, the same components as those shown in FIG. 1 will be described with the same reference numerals. Is omitted. In these drawings, reference numeral 30 in the drawings is a tubular case having a substantially triangular cross section and having both side surfaces 30a closed. A drum 31 having a small diameter is rotatably provided on the apex side of the case 30 via bearings 32 provided on both side surfaces 30a, while the drum 31 is provided on the bottom side of the case 30. Similarly, a drum 33 having a larger diameter is rotatably provided via a bearing 34. A scale 35 having the same scale as that shown in FIG. 1 is wound around the drums 31 and 33 in an endless band shape. Further, a handle (rotating means) 36 for rotating the drum 33 is attached to one shaft of the drum 33 protruding from the case 30. On the other hand, on the surface of the case 30, a window 37 extending in the longitudinal direction is formed along the apex of the case 30, and a transparent cover is provided on the window 37 so that the internal scale 35 can be read. It is provided.

When reading an unknown dimension in the drawing with the scale corresponding to the arbitrary scale configured as described above, first, a line segment A in which the dimension (for example, 10 m) in the drawing is displayed on the window 37 of the case 30. -Position B and align one end A with the 0 scale of scale 35. Then, the drums 33, 31 are rotated by the handle 36 to move the scale 35, and the other end B is aligned with the scale connecting line 14 of the scale 35 having a corresponding size (for example, 10 m). As a result, the scale line 15 crossing the scale connecting line 14 becomes the scale factor of the drawing. Therefore, from this state, along the window 37 of the case 30 along an unknown dimension portion, one end thereof is aligned with the 0 scale of the scale, and the other end of the scale connecting line 14 is graduated. By reading, the actual size of the unknown size part can be obtained.

Therefore, even with the scale corresponding to the arbitrary scale of this example, the scale ratio of the drawing can be read by simply rotating the handle 36, and thus a supplementary scale or the like unlike the conventional one is not required, and therefore the scale can be handled. Is easy. Also at this time, since the line connecting the scales 0 in the upper and lower stages of the scale 20 is orthogonal to the reference lines 10 and 12, align this line with the end A of the line segment AB and roll the roll 21. When rotated, the one end A and the scale 0 do not shift in the left-right direction, and the reading can be further easily performed. In addition, since the entire case 30 has the same shape as a general scale, the scale 35 seen from the window 37 is set in the same manner as a normal scale after reading the scale ratio. Therefore, it is possible to read the actual size of the unknown size portion in the drawing very easily as in the first embodiment.

[0024]

[Effect of device]

 As described in detail above, according to the scales according to any of claims 1 to 3, it is easy to handle and extremely easy without using a separate auxiliary scale unlike the conventional ones. It is possible to read the dimensions in the drawing that are scaled / enlarged to any magnification. Further, in particular, like the invention described in claim 4, in the invention described in claim 2 or 3, the line connecting the scale 0 in the standard size of the scale and the scale 0 in the 1 / n size is the upper and lower stages. If it is made orthogonal to the reference line, the 0 scale position on the scale does not move to the left or right even if the roll-shaped material or the drum is rotated, so that the other end can be more easily aligned with the scale connection line. Such an effect can be obtained.
