发明名称 Double ended key ring
摘要 The present invention provides a double ended key ring that includes a pair of key holders for retaining a set of keys. The key holders are movably connected to a central housing and are biased to retract into a pair of seats located at the ends of the housing to prevent the removal of the keys from the key holders. When the key holders are pulled away from the housing, the keys may then be removed from the key holders. The biasing mechanism for the key holders is located entirely within the housing. To this end the housing includes a central passageway that has a narrow bore, at one end, to preferably slidably receive a spring loaded lock pin that projects through the bore and is connected to one of the key holders. In order to permit the spring loaded lock pin and key holder to be assembled, the other end of the bore remains open until closed by a bushing. The bushing includes a tubular sidewall and an endwall having another narrow bore. Another spring loaded lock pin is slidably extended through the bore of the endwall and is connected to the other of key holders, preferably as a subassembly. The bushing is then connected within the other end of the passageway by a force fit.
