Description

[Technical Field]

[0001] The present invention relates to a pipe ruler having a grooved cross section and a stopper attached thereto. [Background technology]

[0002] Traditionally, tape measures and curved rulers have been used to measure marking positions, but to measure pipes, there are curved rulers whose straight part is placed on the pipe, etc. (see Patent Document 1), and there are also measuring rules with stoppers (see Patent Document 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility model registration No. 1987-79101 [Patent Document 2] Design Registration No. 1072830 Summary of the Invention [Problem to be solved by the invention]

[0004] When marking dimension lines on a small-diameter, short pipe, one hand holds a mechanical pencil, and the other hand aligns the end of the pipe with the zero point position of the measuring tool until the marking is completed. However, there are the following problems with holding the cylindrical pipe and the existing measuring tool with one hand without them shifting.

[0005] In the case of a tape measure, the surface of the scale tape and the side of the pipe are curved in opposite directions, making it difficult to align the scale.

[0006] In the case of a curved ruler, the thin side of the scale is aligned with the curved surface of the pipe, so it is prone to slippage.

[0007] In the invention of Patent Document 1, the measuring tool and the pipe slide in the longitudinal direction, but when the measuring tool is placed on a pipe with a smooth surface, the zero point position may shift from the end of the pipe that was initially aligned.

[0008] In the invention of Patent Document 2, it is possible to easily set the pipe end to the zero point position by aligning it with the stopper, but since there are no dimensional scales, it is not possible to mark any dimension.

[0009] The present invention has been made to solve these problems. [Means for solving the problem]

[0010] To solve the above problems, the invention of claim 1 is characterized by a U-shaped or V-shaped groove that is fitted onto a pipe and conforms to the pipe, a scale on the surface of the groove, and a stopper in the groove at the zero point of the scale. Furthermore, the invention of claim 3 is characterized by a gripping aid on the surface opposite the groove. [Effects of the Invention]

[0011] According to the present invention, the pipe fits into the groove, preventing it from slipping, and the zero point can be quickly positioned simply by placing the end of the pipe against the stopper. Therefore, by aligning the scale and grip assisting part with the pipe and gripping it tightly, the pipe can be held firmly without slipping, making marking easier.

[0013] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiments are examples for explaining the present invention, and are not intended to limit the present invention to only these embodiments.

Furthermore, the same components in each drawing will be designated by the same reference numerals whenever possible, and redundant explanations will be omitted. DETAILED DESCRIPTION OF THE INVENTION

[0014] As shown in Figures 1 to 5, the pipe ruler 1 is shaped to fit into a pipe P and conform to the pipe P, and is composed of a U-shaped or V-shaped groove 2, a scale 3 on the surface of the groove 2, and a stopper 4 in the groove at the zero point of the scale.

[0015] As shown in FIGS. 4 and 5, the scale portion 3 may be provided on two surfaces of the surface portion of the groove portion 2.

[0016] As shown in the figure, a gripping aid consisting of gripping aids 5 to 7 may be provided on the surface opposite to groove 2. The figure is an example, and gripping aids 5 to 7 may be separate parts or may be integrated, and may be polygonal or ring-shaped, or any other shape is acceptable.

[0017] <Example> Next, an embodiment of the pipe ruler 1 according to the present invention will be described. First, the gripping aids 5 to 7 are grasped with the middle finger, ring finger, little finger, and palm.

[0018] The pipe P to be measured is placed in the groove 2 of the pipe ruler 1, and the end of the pipe P is brought into contact with the stopper 3 to set the zero point.

[0019] Hold the pipe P with your thumb and use the scale part 3 as a reference to mark a position of any dimension with the other hand.

[0020] In addition, when the pipe P is installed or placed on a stand, the grooved part 2 side of the pipe ruler 1 is placed on the pipe, the grip auxiliary part 5 is held with the thumb and index finger, and the end of the pipe P is placed against the stopper 3 to set the zero point, and the marking is made at the position of any dimension using the scale part 3 as a reference with the opposite hand.
