Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a ruler suitable for use in a meeting for design (design) drawings.

[Background of the invention]

At the stage of designing / manufacturing interior decoration, advertisements, displays, etc., the client and the designer hold a meeting using a design drawing (design drawing) in which only the dimensions of the main parts are entered. This meeting may be conducted by a face-to-face interview, but in general, it is often by telephone contact. in this case, The design drawing that has been reduced in size is sent from the designer side to the client side by facsimile, etc., and a meeting is held by telephone while looking at the reduced drawing. The scale of the reduced drawing is A3 → A4,
B3 version → like B4 version It is often doubled (about 0.71 times). This is to make it easy to send by facsimile and at the same time make it possible to see the drawings at a glance. However, when trying to read the size of the part where the size is not written in the reduced drawing during the meeting, after reading the size with a normal real length scale ruler, the size is read with a desk calculator or the like. It was troublesome to calculate the times. Alternatively, when considering the fit of a figure or design that the actual length is known on the drawing, the actual size should be the same as the actual size. I had to calculate doubles. Since the meeting work using the design drawings is performed immediately before the start of construction, and because quickness and accuracy are required, such conversion work of variable length dimensions has been a major obstacle to operations. Conventionally, each side of a slender rectangular flat plate or triangular flat plate has 1
The length per unit is Those with a variable-length scale such as
58-14798). In addition, 1 / 100m, 1 / 200m, 1 / on each side of a business card-sized rectangular plate
With a real length scale such as 300 m (Jitsuko Sho 47-15233)
A rectangular flat plate with rectangular or rectangular window holes with real length scales such as 1 / 100m, 1 / 200m, 1 / 300m on each side of the window and each side of the window (Actual No. Sho 49-90146) Was also known. However, the above-mentioned Japanese Patent Laid-Open No. 58-14798 has only various variable length scales per unit (for example, 1/100 m), and other units such as 1/200 m and 1/300 m. The variable length for the real length scale cannot be measured. In other words, the magnification of the reduced drawing is A3 → A4, B3 as described above.
Version → like B4 version In view of the current situation that is often doubled (about 0.71 times), it had the drawback of low utility value. In addition, in the case of Jitsuko Sho 47-15233 or Jitsukai Sho 49-90146, only the actual length scales such as 1 / 100m, 1 / 200m, 1 / 300m are attached, and the variable length Had to be converted using a desktop calculator, etc., and the requirements for quickness and accuracy of the meeting work based on the design drawings described above could not be satisfied. [Object of the Invention] The present invention solves the above problems, and has a plurality of types of actual length and high versatility. The purpose is to provide a ruler that can immediately compare the variable length dimensions of. [Configuration of the Invention] In order to achieve the above object, the invention is one or more windows having two sides parallel to the long sides of the outer periphery of the ruler body in the central portion of the ruler body made of a business card-sized rectangular flat plate. A hole is provided, and a plurality of types of actual length scales are provided on the outer periphery of the ruler body and the inner periphery of the window hole. The variable length scale and the real scale are installed next to each other for each type of the actual length scale. In the invention described in claim 2 of the utility model registration claim, the type of the actual length scale is 1 / 100m, 1 / 200m, 1 / 300m, 1/50
It is characterized by being 0 m. Further, the invention as claimed in claim 3 of the utility model registration is characterized in that one window hole having two sides parallel to the long side of the outer circumference of the ruler body is rectangular.

Furthermore, it is characterized in that a plurality of window holes having two sides parallel to the long side of the outer circumference of the ruler body are arranged in a slit shape. [Embodiment] The ruler of the present invention will be described below with reference to an embodiment shown in the accompanying drawings. FIG. 1 shows the first embodiment, in which 1 is a ruler in which one rectangular (similar) window hole 4 is opened in the center of a rectangular plate with a large business card (long side 91 mm, short side 55 mm). The main body of the ruler 1 is usually made of aluminum with a thickness of 0.7 mm. This is because aluminum has dimensional stability, but it goes without saying that another material (plastic) may be used as long as it has the same effect. Four kinds of real length scales 2 are provided on each inner side of the window hole 4. That is, in the drawing, the side facing up (lower side) is 1/100 m, the side facing down (upper side) is 1/200 m, the side facing right (left side) is 1/300 m, and the side facing left (right side) is 1 / m. It has a real length scale of 500 m. In addition, the outer circumference of the ruler body 1 has the above-mentioned actual length. The variable length scale 3 of double is installed close to each other back to back.
That is, measure the actual length scale 2 of 1 / 100m on the lower side of the window hole 4 and correspond to it. The double-length variable scale 3 can be immediately measured on the lower side of the ruler body 1 as viewed. FIG. 2 shows the second embodiment. The ruler body 1 shown here is the same as the case of FIG. 1 in that it is a rectangular plate with a size of a business card, but three slits (parallel to the long sides 1a and 1b of the ruler body (specifically Has a length of 70 mm and a width of 3 m
m) window holes 5, 5 ', 5 "are provided. The long sides 1a, 1b and the slit-shaped window holes 5, 5', 5" are each side.
Of the 8 parallel sides consisting of 5a and 5b, 5a 'and 5b', 5a "and 5b", the upward facing sides 5b ", 5b ', 5b, 1b are 1 / 100m, 1 / 200m from the bottom. , 1 / 300m, 1 / 500m 4 kinds of real length scale 2
Is provided, and each of the downward facing sides 1a, 5a ″, 5a ′, 5a has 1
The actual length of the actual length scale of / 100m, 1 / 200m, 1 / 300m, 1/500 A double variable length scale 3 is provided so that they are back to back. The numbers on the real length scale 2 and the variable length scale 3 are both read left. Further, in the embodiment, the scaling ratio of the scaling length scale 3 is set to the actual length. The reason for doubling is that it is highly versatile. Although the actual length scale and the variable length scale display method were not particularly described, the scale created by printing or baking, whether mechanically or electrically or chemically engraved or directly written, was used. You may attach the sheet to the ruler body. Furthermore, in order to make it easier to distinguish between the actual length scale and the variable length scale, the actual length is color coded such as black and the variable length scale is red.
It will be easier to use if you put a * mark on only one of the letters that indicate the unit. [Effects of the Invention] As described above, according to the present invention, one or a plurality of window holes having two sides parallel to the long sides of the outer circumference of the ruler body are provided in the central portion of the ruler body made of a business card-sized rectangular flat plate. And
There are multiple types of real length scales on the outer periphery of the ruler body and the inner periphery of the window hole. Since the variable length scales of are set back to back for each type of the actual length scale, for example, the distance between any two points on the drawing is read by the variable length scales and immediately It is possible to know the long dimension, and conversely, when knowing how the desired real length figure will be on the reduced drawing, the desired dimension read on the real length scale There is an advantage that it is possible to make an instant judgment by placing the variable magnification scale side installed back to back on the drawing.

In addition, the present invention provides a plurality of types of real length scales and their variable length scales on the outer periphery of the ruler body and on the inner periphery of one or a plurality of window holes provided in the central portion. When the types are all 1 / 100m, 1 / 200m, 1 / 300m, 1 / 500m,
Although it is a small ruler body that is the size of a business card, it can quickly handle a wide variety of actual lengths, and it has the effect of enabling quick and easy meeting work on drawings. Further, in the present invention, since the actual length scale and the variable length scale are provided on the outer circumference of the ruler body and the inner circumference of the window hole, there is no inconvenience even if the ruler body is made of an opaque material such as aluminum, It has the advantage that the scale can be directly applied for measurement. Furthermore, when one window hole having two sides parallel to the long side of the outer circumference of the ruler body is a rectangle, a plurality of types of real holes are formed on the four sides of the ruler body and the four sides of the rectangular window hole. Long scale and the actual long scale The variable-length scales of can be installed back-to-back for each type of the actual length scales, so that the ruler body can be conveniently used while rotating and the convenience is excellent. Furthermore, when three equal holes having two sides parallel to the long side of the outer periphery of the ruler body are arranged in a slit shape, three long holes and two sides of the slit-shaped window hole are provided. Multiple types of actual length scales and the actual length scales Since the variable length scale of can be installed back to back for each type of the actual length scale, it can be used by sliding the ruler body in the direction orthogonal to the long side according to the type of the actual length scale.
It has the effect of being excellent in usability.
