JPS60155903A - Method and instrument for measuring length of long article - Google Patents

Abstract

PURPOSE:To make it possible to measure length easily and accurately alone, in measuring the length of a long article to be measured, by aligning the marked line of a magnet to the divided position of said article to be measured and inlaying the hook of a scale with a hooking groove hole in an inserted state to perform measurement. CONSTITUTION:A marked lines 4 are scored to a substrate 1 comprising a magnet so as to position on the longitudinal extended line of the hooking groove hole 2 provided to said substrate 1. When the length of an article 10 to be measured is longer than a convex rule 6, the magnet 1 is placed on the article 10 to be measured so as to allow the line 11 of a divided position to coincide with the marked lines 4 and the hook 7 provided to the leading end of the convex rule 6 is inlaid with and inserted in the hooking groove hole 2 and this operation is repeated plural times. Therefore, when the article 10 to be measured is longer than the measurable length of the rule 6, the divided position 11 is made to coincide with the marked lines 4 to make it possible to accurately measure a length. Furthermore, when the rule 6 is carried, the magnet 1 is received in the magnet receiving part 9 of a rule case 5 to be capable of preventing the loss of said magnet 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a measuring method and measuring instrument that can be used independently to measure the length of long steel objects.

When measuring the length of a long object, etc., if the measurable length of the convex rule is insufficient for the length of the object to be measured,
i! It is necessary to measure the length by dividing it into one section. Conventionally, in such a case, in order to align a part of the convex rule with the divided position, two people, an aligner and a measurer, had to carry out the measurement work. In addition, it is difficult to fix the hook of the convex rule to the base point of the measurement when the length is within the measurable length of the convex rule.

The present invention solves these problems and makes measurement possible even by one person.The present invention is characterized by providing a hook slot 2 in a substrate made of a magnetic material, and A measurement aid is made by carving a marked line 4 on the longitudinal extension line, and the aid is magnetically attached to the measurement line of the object to be measured (referring to the dividing position or measurement reference point), and then inserted into the hook slot 2. A method of inserting the hook at the tip of a convex rule and measuring the length of both or one of them using the magnetized position as a reference point, and the method of measuring the length of the same measuring aid.
-2~ (Measuring instrument) A measuring instrument with a measuring aid detachably attached to one side is provided.

Details will be explained below based on the drawings.

As shown in FIGS. 1 and 2, in order to store the magnet 1 on one side of the case 5, a concave magnet storage portion 9 corresponding to the shape of the magnet is provided, and a core is placed approximately in the center of the magnet storage portion 9. A rod 8 is installed protrudingly. A through hole 3 into which a core rod 8 can be inserted is provided approximately at the center of the magnet 1 having a shape corresponding to the shape of the magnet storage portion 9, and a convex rule hook 7 is provided symmetrically around the through hole 3. A hook slot 2 is drilled to the extent that the hook slot 2 can be inserted thereinto, and a marked line 4 is carved on the left side of the extension line of one side of the upper side of the hook slot 2.

The present invention has the above-described structure, and in use, as shown in FIGS. 2 and 3, the gauge line 4 of the magnet 1 is aligned with the dividing position 11 of the object to be measured 10, and the magnet 1 is magnetically attached. Afterwards, the hook 7 at the tip of the convex rule 6 is inserted into the hook slot 2. At this time, it is magnetically attached so that the upper side of the hook slot 2 on the extension of the marked line 4 is on the convex rule 6 side. Next, extend convex rule 6 and measure the length. Furthermore, if the object to be measured is longer than the measurable length of the convex rule,
Mark the division position at the length measurement limit point and repeat the process as above.

When storing the magnet 1, the through hole 3 of the magnet 1 is inserted into the core rod 8 of the case 5, and the magnet 1 is stored in the magnet storage section 9. At this time, if the case 5 is not made of a magnetic material, it will easily fall off, so a magnetic material such as steel is attached or embedded in a portion of the magnet storage section 9. Furthermore, with the magnet stored in this manner, it is adsorbed to the side wall of a desk 12 or the like and stored as shown in FIG.

” As another embodiment of the measurement aid of the present invention, the fifth
As shown in the figure, an auxiliary tool is detachably screwed onto one side of the measuring instrument, or as shown in FIG. 6, it is detachably attached using a folding pin.

Since the present invention has the above-described configuration, length measurement work can be easily and accurately performed by a single person. Further, by storing the magnet in the magnet storage part, there is an effect that the magnet will not be lost, and by storing the magnet by suction on the side wall of a desk or the like, the convex rule will not be lost.
