Tape Measure with Compact Retraction System
A tool, such as a tape measure, including a spring-based retraction system is shown. Various spring-based retraction system embodiments are configured to decrease the size occupied by the spring within the tape measure housing, which consequently reduces tape measure housing size providing a more compact tape measure. Various spring-based retraction system embodiments are configured to control retraction of the tape measure in a manner that reduces whip or otherwise controls tape blade retraction. Some retraction system embodiments utilize a reduction gear train, and others utilize a compression spring and a transmission system that converts rotational movement of the tape reel to axial movement, which compresses the spring.

Tape Measure with Epicyclic Gear Drive for Tape Retraction
A tool, such as a tape measure, including a spring-based retraction system is shown. The retraction system utilizes an epicyclic gear train coupled between the tape blade winding reel and a rotating arbor or axle within the tape measure. A spiral spring has an outer end coupled to the reel and an inner end coupled to the axle. The gear train may be a reduction gear train such that the axle rotates slower than the reel. By coupling the spiral spring between the gear train input and gear train output, high energy density springs may be used, which may allow for decrease in housing size, increase in tape length or thickness for a given housing size, and/or advantageous retraction speed control.

Ergonomic tape measure
An ergonomic tape measure having a side which has a protruding surface that fills at least a part of the gripping cavity of an operator's hand and provides a comfortable and secure feeling grip when holding the tape measure. The tape measure can have a grip swell surface which fills part or all of the gripping cavity of an operator's hand. The tape measure can have a grip swell side center region which protrudes from a grip swell plane and into the gripping cavity of an operator's hand.

COMBINATION MEASURING TAPE/CHALK MARKER HOLDER
A combination measuring tape/chalk marker holder includes a main housing and a chalk retention pocket. The main housing has a main housing shell with a base and a back plate. The main housing is an equilateral triangular prismatic body with two outwardly curved lateral walls meeting at an apex. Within the housing, a locking reel holding a flexible measuring tape is releasably engaged with a locking hub formed on the back plate. The measuring tape extends through a portal formed in one of the outwardly curved lateral walls. The chalk retention pocket is fixed to and extends from the back plate. The pocket has a base parallel to and coextensive with the main housing base, two parallel lateral walls, and a flexible chalk retention member. The chalk retention pocket is flexible and removably retains a convex lensate marking body. A rotatable foot enables the holder to stand erect.
APPARATUS AND SYSTEM FOR MEASURING DIMENSIONS OF FREIGHT ITEMS
An apparatus for measuring a dimension of a freight item. The apparatus includes an elongate gauge member having a sequence of machine-readable codes visible along its length. Each of the machine-readable codes represents a length value corresponding to a position along the gauge member. The apparatus also includes a marker device, movable along the gauge member, for designating a selected position. The marker device includes a machine-readable reference symbol on an external surface thereof, with the reference symbol being located on the marker device such that in use the reference symbol on the marker device and a subset of the machine-readable codes on the gauge member are simultaneously visible. In a preferred embodiment the elongate gauge member includes a coilable tape and the marker device includes a housing within which the coilable tape is enclosed. A system including the measuring apparatus together with a mobile computing device is also disclosed.
