RULER
Document Type and Number:
Japanese Patent JP2019174430
Kind Code:
A
Abstract:
To provide a ruler for avoiding the problems that when a conventional metal ruler has a length exceeding 30 cm, there is an inconvenience that it does not fit in the case of carrying or storing, that the convex has a scale on the concave surface side of the tape, and has a hook that protrudes and is fixed to the convex surface side of the curve at its tip, so that the tip of the tape could not be measured by fitting it to the measurement object. and that the tape is always pulled by the spring in the case, and the case is inconvenient in terms of stable work such as being easy to fall sideways and heavy.SOLUTION: A low rectangular storage case having a straight tubular storage section with a square cross section, provided with a hook that can change the direction of any of the curved irregularities at the tip of a ruler made of a flexible tape having a scale on the curved tape surface. The tape can be bent and stored, and it can be smoothly inserted and removed during measurement, and its movement can be measured stably by the friction force with the case due to its own repulsive force and the bend, and it can be stored and carried after use.SELECTED DRAWING: Figure 11
