The measuring instrument for measuring a tape measure includes an opposing clamping plate 2 having an open upper end for clamping both side plates of a box-shaped case sandwiching both edges of a metal tape measure housed in the box-shaped case. The extension of the center of both edges of the substrate 1 having a predetermined length is provided by being bent at a right angle, and the other extension of the both edges is connected to the sandwiching plate 2 and is bent at a low angle to be a bent portion 3 to be bent. The part 3 is cut vertically at one end and inclined at the other end. In addition, it is convenient to form a holding hole 4 of a tape measure about the size of a fingertip near both ends of the substrate 1. [Effect] The measuring aid for measuring a tape measure has a simple shape and is easy to manufacture. By using this, it is possible to measure even when the box-shaped case cannot be brought into contact with one end of the measuring point.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a measuring aid for a metal tape measure in a box-shaped case.

[0002]

[Prior art]

 Conventionally, when measuring the length using a metal tape measure in a box case, there is no problem when measuring the outside, but when measuring the inside, that is, the inside method, the box case can not contact one end Sometimes there is an inconvenience that measurement cannot be performed directly.

[0003]

[Problems to be solved by the invention]

 The present invention does not provide a measuring aid for measuring the inner method using a metal tape measure even when the box-shaped case cannot be abutted on one end.

[0004]

[Means for Solving the Problems]

 Here, the inventor of the present invention uses a predetermined length of the opposing holding plate 2 having a widened upper end for holding both side plates of the box-shaped case sandwiching both edges of the metal tape measure housed in the box-shaped case. The center extension of both edges of the substrate 1 is bent at a right angle, and the other extension of the both edges is connected to the holding plate 2 and bent low at a right angle to form a bent portion 3, one end of which is bent. And found a measuring aid for a tape measure with the other end cut at an angle.

[0005] Further, it has been found that it is convenient to form a holding hole 4 of a tape measure as large as a fingertip near both ends of the substrate 1.

[0006]

[Embodiment of the invention]

 Metal tape measures are available for general use with a width of 15 to 18 mm or for professionals with a size of 20 to 22 mm, so both sides of the box-shaped case sandwiching both edges of the metal tape housed in the box-shaped case The thickness between them is different. Therefore, the interval between the two holding plates 2 that hold the both side plates in the measuring instrument made of a metal tape measure also depends on the thickness between the two side plates. The shape of the holding plate 2 is usually rectangular.

The upper ends of the two holding plates 2 are widened to make it easier to insert a metal tape measuring box-shaped case from above. It is preferable that the inner surface of the holding plate 2 be provided with a non-slip so that the positions of the both side plates of the metal tape measure are not easily moved. In this case, the non-slip may be formed by directly processing the metal surface into a rough surface or by applying a non-slip tape.

The two holding plates 2 are provided by bending the central extensions of both edges of the substrate 1 having a predetermined length at right angles. Therefore, the width of the substrate 1 is equal to the distance between the opposing holding plates 2, but the length has an important meaning. That is, when using a metal tape measuring aid, the scale of the tape measure at the other end of the substrate 1 is read by aligning one end of the substrate 1 with one end of a portion to be measured. If it is added, the length of the measurement point can be obtained. Therefore, it is preferable that the length of the substrate 1 is a sharp length such as 20 cm or 30 cm (sometimes equivalent to one length).

The extension of the other part of the substrate 1 without the sandwiching plate 2 is connected to the sandwiching plate 2 and bent at a low angle to a bent portion 3. The other end is cut at an angle. Here, the bent portion 3 may be as small as about 5 mm in order to ensure the flatness of the substrate 1 and to provide the effect of holding the holding force of the holding plate 2. If the bent portion 3 has an upward slope from the end to the holding plate 2, the base of the holding plate 2 is further reinforced, and the holding force is strengthened.

In addition, since the opposite bent portion 3 is cut at one end vertically and at the other end at an angle, the former has a right-angled one end to be measured, and the latter has an acute-angled end. In addition, there is the convenience that the substrate 1 can be easily contacted.

In addition, if the holding hole 4 of the tape measure as large as the fingertip is made near both ends of the substrate 1, if a tape measure with no stopper attached is used, it is opened on the substrate 1 at the time of measurement. When the tape measure surface is pressed with the fingertip toward the holding hole 4 of the tape measure, the movement of the tape measure can be temporarily stopped, which is convenient for measurement. The holding hole 4 of the tape measure is suitably a square having a side of about 18 mm or the like. If you cut out a square, you can copy and use each shape in the work.

【Example】

 The dimensions of the measuring aid for a metal tape measure in a box-shaped case according to the embodiment are shown below. Fig. 1 shows a measuring aid used for a metal tape measure with a scale width of 22 mm. A stainless steel plate with a thickness of 0.5 mm was used as a whole, and the substrate 1 was 35 mm wide, 20 cm long and folded. The height of the bent portion 3 is 5 mm, and the bent portion 3 is cut with one end vertical and the other end inclined. In addition, a square having a side of 18 mm is cut out near both ends as a holding hole 4 of a tape measure on the substrate 1. The holding plate 2 is a square with a side of 50 mm and the top 5 mm is widened, and FIG. 2 shows a use state in which a metal tape measure is inserted into this. Some metal tape measures in a box-type case have a metal fitting for belt hanging on the side plate. In such a case, it is better to remove the metal fitting before use.

[0013]

[Effect of the invention]

 The measuring aid for metal tape measure in a box-shaped case according to the present invention has a simple shape and is easy to manufacture, and by using this, it is possible to measure even when the box-shaped case cannot be brought into contact with one end of the measuring point To
