    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.

    摘要翻译： 本发明提供了一种双端密钥环，其包括一对用于保留一组密钥的密钥保持器。 钥匙保持器可移动地连接到中央壳体并且被偏压以缩回到位于壳体的端部处的一对座位中，以防止钥匙从钥匙扣上移除。 当钥匙架从外壳拉出时，钥匙可以从钥匙扣上取下。 钥匙座的偏置机构完全位于外壳内。 为此，壳体包括中心通道，该中心通道在一端具有窄孔，以优选地可滑动地容纳弹簧加载的锁定销，弹簧加载的锁定销突出穿过孔并连接到钥匙保持器之一。 为了允许组装弹簧加载的锁定销和钥匙架，孔的另一端保持打开，直到被套管封闭。 衬套包括管状侧壁和具有另一窄孔的端壁。 另一个弹簧加载的锁定销可滑动地延伸穿过端壁的孔并且连接到另一个键保持器，优选地作为子组件。 然后通过力配合将套管连接在通道的另一端内。
