Abstract

A compasses writing implement includes a compasses body having two compasses legs mutually pivotable between closed and splayed-out states. A writing lead is mounted in one of the compasses legs. A protective cap is or can be fitted onto the free end of at least the compasses leg holding the writing lead, to shield the free ends of the two compasses legs in the closed state from the outside. The protective cap has a passage for the writing lead at a distal end remote from the compasses body in the fitted state. The writing lead and the fitted protective cap are mutually displaceable between a release state and a retention state. In the release state, a lead tip of the writing lead protrudes through the passage of the protective cap to the outside and in the retention state, the writing lead is retracted in the interior of the protective cap.

Dependent claims

A compasses writing implement, comprising:

a compasses body including two compasses legs having free ends and being mounted pivotably relative to one another between a closed state and a splayed-out state;
a writing lead held on one of said compasses legs and having a lead tip;
and
a protective cap fitted or to be fitted onto said free end of at least said compasses leg holding said writing lead for shielding at least said free end from the outside in said closed state;
said protective cap having an interior, a distal end remote from said compasses body in a fitted state and a passage in said distal end for said writing lead;
and
