  • Patent number: 7937843
    Abstract: A compass includes two legs having upper ends interconnected in a leg joint and lower ends with holders for refills or styluses. An adjusting spindle penetrates the legs, in particular, in vicinity of the leg joint. The legs have carrier zones in the form of widenings serving in a region between the leg joint and the free leg ends as a base of an information bearing surface surpassing the width of the legs in their spreading plane. The information bearing surfaces are disposed on both broad sides of the compass and constructed as undivided surfaces projecting from one leg into the region of the other leg. If the compass is closed, two mounting disks of the information bearing surfaces lie congruently above one another and only two outer information bearing surfaces and can be seen. All four information bearing surfaces can be seen in the open state of the compass.
