  • Patent number: 4282733
    Abstract: A finger-retained key holder assemblage has been provided that will prevent the loss of keys when carrying the keys in the hand as in the dark or carrying bundles without having to close the fingers about the keys in the palm of the hand. This key assemblage is secured to the hand by a ring placed upon the third finger or by a button, disk or clip extended over two fingers, a chain depending from the disk and squeezed by the two fingers and a key-supporting bar lying under the fingers and clamped thereto. Keys are loosely suspended from the underside support bar. While the flexible assemblage is secured to the third finger or between fingers, an individual key can be easily selected and grasped by the thumb and forefinger of the same hand and made ready for use for projection into a key hole. As well, the fingers can be closed comfortably about the assemblage to further safely retain the keys in the hand.
