Tape measure

Abstract

Abstract PURPOSE:To eliminate the need for a person who matches a reference line with the start point of an object to be measured and to permit measurement with one person by connecting plural universally flexible link members and a magnet body to the top end, and bending the link members to attract the reference line of the magnet body to the start point of the object to be measured. CONSTITUTION:Link members M1, M2, M3... having respectively an equal length are connected to the top end of a measuring body 2, and a magnet material 4 provided with a permanent magnet 5 is connected to the front end part of the member M1. While the connecting distance between the respective members and the connecting distance between the connecting point in the front end part of the member M1 and a reference line 8 of the body 4 are made equal, a projecting part 9 is formed at one end of the connecting point in the front end part of the member M1, and a fitting hole 10 to be universally flexibly fitted therein with the part 9 is formed at the connecting point in the rear end part of the member M3. The line 8 of the magnet body is attracted to the start point S1 of an object to be measured by bending any of the members M1, M2, M3... and the body 4.
