Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a diameter measuring measure capable of measuring the diameter of an object to be measured by measuring the outer circumference of the object.

[0002]

[Prior art]

 When measuring the diameters of existing structures such as pipes, steel pipe columns with large diameters, trees, etc., conventionally, the diameter was measured by directly applying a tape measure to the edge or using a caliper. However, if the measure cannot be applied directly to the small edge or if the diameter is large, it cannot be measured by the above method, and the measurement is inaccurate, or the measurement has to be troublesome. .

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and an object thereof is to provide a diameter measurement measurer capable of accurately measuring the diameter of an object to be measured by measuring the outer circumference of the object. .

[0004]

[Means for Solving the Problems] The present invention is characterized in that, in a strip-shaped measure, a scale for displaying a length and a scale for displaying a diameter are arranged at both ends in the width direction of the measure in contrast to each other. A diameter measurement measure, and the diameter display scale is characterized in that numerical values converted into diameters are arranged in correspondence with the scales for displaying the length. The scale for displaying the diameter is a diameter measuring measure characterized by arranging an integer scale and a scale that divides the integer into ten equal parts, and further, in the strip-shaped measure, the width direction of the measure. A diameter measurement measure characterized by arranging only a scale indicating the diameter at one or both ends.

[Embodiment of device]

 An embodiment of the present invention will be described below with reference to the drawings.

<A> Overall Configuration of Diameter Measuring Measure FIG. 1 is a perspective view of a diameter measuring measure 1 according to the present invention. The diameter measuring measure 1 is made of a flexible material that does not expand and contract, and is stored in a storage case (not shown) so as to be easily carried when not in use. A scale for measurement is arranged at the end of the diameter measuring measure 1 in the width direction.

<B> Arrangement of Scales A scale for measurement is arranged at the end portion in the width direction of the diameter measurement measure 1 according to the purpose of use. The purpose of use of the present invention is to measure the length of the circumference and to measure the diameter thereof. Therefore, the value calculated by "the length of the circumference divided by the circumference ratio" is used as the length of the circumference. It will be placed in the same place.

<C> Scale Display Method Depending on the purpose of use, required accuracy of measurement, etc., the following scale display methods can be considered.

Display by “circumference value” vs. “diameter value” In FIG. 2, the scale (diameter value) D of the diameter converted to the diameter is displayed corresponding to the scale L for displaying the length (circumference value). Let's make a strip-shaped measure 2. (In Fig. 2, the numerical value converted into the diameter is displayed corresponding to the 5 mm interval of the length display.) Display by "circumference value" vs. "integer value of diameter" In Fig. 3, the diameter is displayed The scale D is a band-shaped measure 3 that is displayed with an integer scale and a scale that divides the integers into ten equal parts. Display by "integer value of diameter" In FIG. 4, the belt-shaped measure 4 is provided with only the scale D for displaying the diameter at one or both ends in the width direction of the belt-shaped measure.

[0010]

[Action]

 The method of using the diameter measuring measure according to the present invention will be described below.

<B> When the cross section cannot be directly measured In FIG. 5, in order to measure the diameter of the existing piping pipe 6 arranged in the existing structure 5, the strip-shaped measures 2, 3 and 4 are used. Make one round along the outer circumference of and measure the circumference. At this time, as shown in FIG. 2, FIG. 3, and FIG. 4, the strip-shaped measures 2, 3 and 4 have a diameter scale indicating a diameter at a position corresponding to a length scale L indicating a circumferential length. Since D is arranged, even if the cross section of the piping pipe 6 cannot be directly measured, its diameter can be measured. If the measured value of the diameter is required to be accurate to the mm unit, use the 3 or 4 band-shaped measures (Figs. 3 and 4) out of the band-shaped measures 2, 3 and 4 on which the scales up to the mm unit are displayed. It can be measured by using it. If the measured value of the diameter is required to be more accurate than the unit of mm, a strip-shaped measure D, which displays the diameter at a position corresponding to the scale L of the length, is displayed on the strip-shaped measures 2, 3, and 4. By using the measure 2 (in the case of FIG. 2, the direct-diameter scale D is displayed in correspondence with the length scale of 5 mm), it is possible to measure a more precise diameter measurement value.

<B> When measuring a thick diameter In FIG. 6, when measuring a thick diameter such as a tree 7, the diameter of the tree 7 is measured by measuring the circumferential length of the tree 7 in the same manner as above. You can

[0013]

[Effect of device]

 Since the present invention is as described above, the following effects can be obtained. <B> Scales that indicate the length and scales that display the diameter are arranged at both ends in the width direction of the strip-shaped measure, so that one measure can measure the normal length and the corresponding length. Both diameters can be measured. <B> Since the scale for displaying the diameter corresponds to the scale for displaying the length, the numerical value converted into the diameter is arranged, so that a more precise diameter can be measured. <C> Since the graduations for displaying the diameter are the integer graduations and the graduation that divides the integers into ten equal parts, the diameter in mm can be clearly measured. <D> Since it is a strip-shaped measure with only the scale for indicating the diameter, it is easy to see with a clear display as a measure used only for measuring the diameter.
