摘要

Measuring device for determining or comparing the respective distances between a target ball (21) and a throwing ball (23) in the boules, boccia and petanque game, comprising a base body (1) with a bottom surface and a surface, a laterally applied circular sighting opening (26) and underlying space such that the circular visor opening having a diameter larger than that of the target ball is movable over the clearance target ball (21) and further centered therein to form a uniformly circumferential annular gap in the form of a sight sight, and above the surface the base body (1) rotatably mounted distance measuring device, characterized in that on the surface of the base body (1) has a bearing and visor plate (5) serving as a visor plate-shaped extension and the visor opening (26) and laterally outside of the base body (1 ) below the storage and Visi erplatte (5) the space for storage and detection of the target ball (21), which is given to both the front and the outside below the bearing and visor plate (5), so that their circular visor opening (26) via the target ball (21 ) and that on the bearing and visor plate (5) rotatably arranged perpendicular thereto, a thrust bearing (12) is applied, that the bearing and visor plate (5) via a radial bearing (6) about an axis of rotation (6 ') from the top of the base body (1) up and down to the front side is pivotable and that on the outside of the top of the thrust bearing (12) on an adapter plate (13) a distance measuring device in the form of an extendable telescopic rod (17, 19), a Bandmaßes or a laser (29) is rotatably mounted for distance measurement and that in the form of a double, downwards bent (20 ') at the end of the telescopic rod (17, 19) or a downwardly offset position tion of the tape measure or the laser (29) a parallax compensation (20, 28) of the measuring line, the distance between the target and throwing ball up to the height of the equator of the throwing ball detecting telescope rod, the length of the drawn tape measure or the determined value of the laser is, according to measuring line (22) from the center of the target ball (21) to the equator (24) of the throwing ball (23).
