A retractable tape measure having a housing with an opening therein through which a portion of the tape extends with the remainder of the tape being coiled around a spring biased reel having a hub around which the tape is coiled. Opposed annular ends on the hub retain the tape coiled therearound. One of the annular ends has a serrated circular peripheral edge with about 100 to about 150 serrations. A first locking mechanism is shiftably mounted on the housing movable vertically into and out of engagement with the tape. Second locking mechanism is shiftably mounted on the housing movable radially into and out of engagement with the serrated edges. The second locking mechanism has a plurality of serrations thereon which when engaged with a plurality of serrations on each annular end provide a positive lock for the tape coiled around the reel hub to prevent further withdrawal of the tape. The second locking mechanism may be spring biased.
Cette invention concerne un mètre à ruban rétractable dont le boîtier comporte une ouverture par où extraire le ruban enroulé autour d'une bobine à ressort de rappel monté sur un axe. Les flasques annulaires opposés de la bobine maintiennent le ruban y enroulé. Un de ces flasques est dentelé sur son pourtour à raison d'environ 100 à 150 dents. Un premier mécanisme de blocage mobile verticalement sur le boîtier permet de bloquer le ruban par compression. Un second mécanisme de blocage également mobile sur le boîtier se déplace radialement pour accrocher les dents du flasque dentelé. Le second mécanisme de blocage comporte également une série de dents qui, une fois en prise avec la dentelure du flasque, assure un blocage sûr du ruban pour empêcher d'en dérouler davantage. Ce second mécanisme peut avoir un ressort de rappel en position de repos.
