Document Type and Number:
WIPO Patent Application WO/2014/122130
Kind Code:
A1
Abstract:
The invention relates to a folding rule (G) which comprises at least four sections (1, 2, 3, 4) that are hinged together, at least the fourth section (4) having two scales (SK1, SK2) for angle measurement and the first section (1) having at least one reading mark (M). The first scale (SK1) for angle measurement and the reading mark (M) are located on the respective section (4, 1) such that the reading mark (M) points to the value of the first scale (SK1), which corresponds to the angle (α) to be measured between the sides (O1, O2) that rest on the second section (2) or on the fourth section (4) when the first section (1) and the fourth section (4) are aligned in parallel and a first lateral edge (1.1) or a second lateral edge (1.2) of the first section (1) rests on a first lateral edge (4.1) of the fourth section (4). The second scale (SK2) for angle measurement and the reading mark (M) are located on the respective section (4, 1) such that the reading mark (M) points to the value of the second scale (SK2), which corresponds to the angle (α) to be measured between the sides (O1, O2) that rest on the third section (3) or on the fourth section (4) when the first section (1) and the fourth section (4) are aligned in parallel and a second lateral edge (1.2) of the first section (1) rests on a second lateral edge (4.2) of the fourth section (4). The invention further relates to a method for angle measurement by means of the folding rule (G).
