초록 ▼

A stopper device for tape measures is disclosed which does not make direct contact with the rule, and therefore, it does not cause erasing of the scale marks on the rule. This is achieved by providing a plurality of protrusions at regular intervals around the circumferential flange surfaces of a flanged spool winding case, and also by providing a stopper unit to be selectively engaged with and disengaged from the protrusions.

대표청구항 ▼

A tape measure, comprising: a housing having an opening to the exterior of said housing; a flanged spool rotatably mounted within said housing and having a pair of spaced apart flange sidewalls, said spool including a plurality of circumferentially distributed protrusions attached to one side of at least one of said flange sidewalls with regular intervals between said protrusions; a measuring tape coiled about said spool between said flange sidewalls and having a free end portion extending through said housing opening, said spool being rotatable to move said tape between retracted and extended positions; lock means for selectively locking said spool against rotation within said housing without directly contacting said tape to selectively prevent extension or retraction of said tape with respect to said housing, said lock means including a spool lock member selectively movable between a first position in which said spool lock member is positioned within one of said intervals between a pair of said protrusions to prevent rotation of said spool and extension or retraction of said tape, and a second position in which said spool lock member is positioned clear of said protrusions to allow rotation of said spool and extension and retraction of said tape, said spool lock member being slidably positioned within an aperture in said housing for movement between said first and second positions, a contact portion of said spool lock member projecting out of said housing and being engageable by a finger or thumb of the tape measure user to selectively cause said spool lock member to slidably move between said first and second positions; said spool lock member having an engagement shoulder; and a catch attached to said housing and having an engagement portion sized to engage and cooperate with said engagement shoulder of said spool lock member when said contact portion of said spool lock member is engaged by a finger or thumb of the tape measure user and thereby slidably moved to position said spool lock member in said first position, said catch engagement portion and engagement should being lockably engageable to hold said spool lock member in said first position to lock said spool against rotation until said catch engagement portion and engagement shoulder are disengaged by the tape measure user to permit slidable movement of said spool lock member into said second position.
