Device for measuring the distances and directions of destinations on road maps

PCT No. PCT/DE86/00247 Sec. 371 Date May 5, 1987 Sec. 102(e) Date May 5, 1987 PCT Filed Jun. 13, 1986 PCT Pub. No. WO87/01442 PCT Pub. Date Mar. 12, 1987.A device for measuring the distance and direction of destinations on road maps from a starting point is suggested which serves for the data input of intermediate destinations in navigation devices. The device comprises an angle measuring plate (10) with a 360-degree scale (13) which is arranged concentrically relative to a central borehole (14) and which begins with the north direction. A bracket (11) is supported at the central borehole (14) so as to be rotatable and carries a measuring tape case (12) at its end area (11b) and a guide (20) for a measuring tape (19) at its opposite end area (11c), the measuring tape (19) being arranged in such a way that, when drawn out of the measuring tape case (12), the measuring tape (19) extends away radially in an outward direction with its one lateral edge over the center of the degree scale (13). The input of distance and directional angle of an intermediate destination can be determined with a single adjustment with this device which has a compact construction, small dimensioning and large measuring range (FIG. 3).
