Tape measure

Abstract

This article is composed of four members: a tape measure tape having a circular cross section with length scales on the front and back, a start side slider having permanent magnets on the front and back, a terminal side slider having permanent magnets on the front and back, and a hanging member capable of hanging the wound part of the tape measure tape. A movable claw member is arranged at the start side of the tape measure tape, and a permanent magnet is arranged on the movable claw member. Both the start side slider and the terminal side slider are freely attached and detached to the tape measure tape. A raising member capable of pressing the surface of the tape measure tape is arranged on the terminal side slider so as to be able to rise and fall about a pivot. A raising operation mechanism is provided which can press and fix the surface of the tape measure tape and release and release it by raising or lowering the raising member. Pressing the surface of the tape measure tape by the raising member prevents the tape measure tape from sliding in the directions of the start side and the terminal side. For example, as shown in the reference perspective view and the reference exploded perspective view, The tape measure tape has inherent straightness and winding properties due to its cross-sectional arc shape, and a winding portion is formed at the end of the tape measure tape by sliding the end slider towards the start side, and the tape measure tape is extended by sliding the end slider towards the end side and the start slider. As shown in reference diagrams of the tape measure tape and reference diagram (1) showing the usage state, by detaching the start slider and end slider from the tape measure tape, it can be used as a leveling staff. Also, for example, as shown in reference diagram (2) showing the usage state, two of this article can be fixed vertically and horizontally to multiple reinforcing bars arranged vertically and horizontally by permanent magnets on the front or back of the start slider and end slider, or by multiple spare permanent magnets on the start slider, and the tape measure can be used when measuring the spacing between reinforcing bars, inspecting them, and taking photographs of the reinforcement state.
