Abstract:
A keyring tool suitable for storage on an expandable coil-type keyring and disconnection therefrom for use in connecting and disconnecting keys to and from said keyring, and comprising a bow portion for connection of the tool to the keyring, said bow portion having at least one circumferentially extending portion having a generally wedge shaped-section extending from a leading edge portion at one side of said circumferentially extending portion towards a stop face at an opposite side thereof, for insertion between one end of the coiled strip of the keyring coil and an axially adjacent part of said coiled strip for threading of said strip through said bow portion for connection or disconnection of the keyring tool thereto or therefrom, respectively, said leading edge portion further being advancable from said one end of said coiled strip into a position between first and second axially adjacent parts of the coiled strip, said position being spaced from each end for axially expanding said keyring coil to a first axial expansion level, said tool then being twistable about a transverse axis extending between said first and second parts of the coiled strip so as to bring said leading edge portion and said stop face into engagement with respective ones of said first and second axially adjacent parts of the coiled strip so as to further expand axially said keyring coil to a second axial expansion level, and retain said keyring coil at said second expansion level, thereby to facilitate connection and disconnection of keys thereto and therefrom.
