Description

[Detailed explanation of the invention] Conventional curved scales had the disadvantage that they would move if not firmly held down when placed on the object to be measured.

Holding it too tightly made my hands uncomfortable, which made work that much worse.

Moreover, when cutting external wall materials or the like using a curved scale, the curved scale itself is thin and does not act as a guide, making it difficult to cut.

The present invention solves these drawbacks and relates to a curved scale that can be held firmly and not moved, and can also be used as a cutting ruler. Then, it is as follows.

A bending notch 3 is formed at the corner of a bent body a consisting of a short plate 1 and a long plate 2, and the bent body a is
The short body 1 and the long body 2 are bent and connected in the vertical direction by changing the directions in which they protrude from each other in the outer length direction to form guide and abutment plates 4 and 5. Measuring scales 6 are formed on the front and back sides of the plate 2.

In addition, this product is preferably formed by punching and pressing using stainless steel, steel, aluminum, etc., or the curved length main body a and the guide contact plates 4 and 5 may be simultaneously molded by plastic processing. .

In the present invention, as mentioned above, the guide and abutment plates 4 and 5 are connected vertically to the short plate 1 and the long plate 2 with different directions of protruding from each other. As shown in FIG. 4, the curved scale body a is placed on the object to be measured 7, and one of the guide and abutment plates 4 and 5 is brought into contact with the side surface of the object to be measured 7. Since it is tightly fixed to the object to be measured 7, it is only necessary to lightly press the curved scale body a with one hand, and one scale can be used with the other hand to perform tasks such as marking, marking, and drawing lines.

Since there is no need to worry about the bending scale main body a moving in this way, the work efficiency is greatly increased compared to conventional bending scales.

At this time, the guide and abutment plates 4 and 5 serve as guides, making marking and line drawing extremely easy.

Also, when cutting exterior wall materials, the guide and contact plates 4 and 5 act as guides to move the cutter, allowing for efficient and clean cutting. As described above, the present invention allows the bending length main body a to be easily fixed by simply abutting one of the guide and abutment plates 4 and 5 against the side surface of the object to be measured (7). It is possible to make marks, draw lines, and cut by guiding the abutment plates 4 and 5 that are not in contact with the guide, and also provides a convenient curved scale that can be used on both sides. .

The structure of this product is also simple, just by bending and connecting the guide and abutment plates 4 and 5 to the outer lines of the short plate 1 and the long plate 2, making it possible to mass-produce the product and providing the product at a lower price. At the same time, since the bending notches 3 are provided at the corners of the bending length main body a, alternating bending of the guide-cum-contact plates 4 and 5 can be easily and accurately performed, which is a factor for mass production. It has excellent practical effects.

Claims (1)

[Scope of utility model registration request] A bending notch is formed at the outer corner of the bent main body consisting of a short plate and a long plate, and the direction in which the outer longitudinal edges of the short plate and the long plate of the bent main body are bent relative to each other is determined. A curved length characterized in that a contact plate that also serves as a guide is formed by vertically connecting the bending notches, and measuring scales are formed on the front and back sides of the short plate and the long plate.
