A deployable stabilizer cooperates with a tape of a tape measure to stabilize the tape measure with the tape extended therefrom to facilitate hands free stability of the tape measure. The stabilizer may be pivotally coupled with a body of the tape measure to facilitate pivoting between a deployed and a stowed position. The stabilizer may comprise an extendable member that is guided by channels defined by tape measure body. Locations or orientations of pivot holes or channel guides may result in contact of the bottom of the tape in an extended position with a top of the stabilizer in a deployed position to facilitate stability of the tape measure body.

Proposed is a belt holder for a tape measure including a holder body, a clip holding part, a locking bracket, a bracket spring, a push button with a one-way rotation inducing groove, a push button spring, and a position maintenance pin, wherein due to an operation of the push button and the elastic force of the push button spring, a locking jaw of the locking bracket can be easily switched between locked and unlocked states as the push button is pushed in and out.

A retractable rule assembly includes a housing, a coil spring assembly, and a replaceable blade cartridge. The coil spring assembly includes a first coupler. The replaceable blade cartridge is configured to be selectively mounted in and removed from the housing when a displaceable panel of the housing is in an open position. The replaceable blade cartridge comprises an elongated blade, a reel, and a second coupler. The second coupler is constructed and arranged to engage with the first coupler when the replaceable blade cartridge is mounted in the housing, such that the first coupler and the second coupler become rotatably coupled. When the first coupler and the second coupler are rotatably coupled, the coil spring assembly is biased to rotate the replaceable blade cartridge in a direction that winds the blade onto the reel when the blade is extending outwardly of the housing.

A sports measuring device to measure a standard distance during a sporting contest comprises a casing, a reel mounted in the casing, and a measuring cord wound around the reel and extending outwardly through an aperture in the casing. When entirely unwound from the reel with a distal end being tautly extended away from the first end of the casing, a length of the measuring cord between the distal end and a plane defined by the first end of the casing equals the standard distance defined by a specific rule of play of the sporting contest. The device further comprises an anchoring assembly partially disposed inside the casing and permitting movement of a retractable ground spike between a stored position and an extended position, the extended position enabling the retractable ground spike to be affixed to a ground surface of a field of play of the sporting contest during use.

A spooled marking apparatus for defining layouts of athletic fields, playing surfaces, home improvement projects, and the like is presented herein. The reel includes a housing within which a spool is disposed retaining an elongated marking device wound thereon. The housing includes an opening through which a free end of the elongated marking device is allowed to pass through. The free end of the elongated marking device includes a fastener, and the housing includes a lock and a roller handle.
