| 摘要 |
<p>The invention concerns a key-ring consisting of a ring, preferably circular, having a first complete coil (1) and at least one section of a second coil (2), preferably a second coil, contiguous with the first coil and elastically returned against the first coil, the first coil and the second coil being separated by an interstice extending between the two free ends (3, 5) of the two coils and between the two coils. The interstice through which a key is passed to be fixed on the key-ring or to be removed therefrom, is provided a nail-shaped tenon (9) having a leading edge (10) sufficiently thin to be inserted into the interstice and sufficiently wide to space apart sufficiently the two coils from each other to allow through a key therebetween when the tenon is rotated, and means for fixing (7, 8, 12) the tenon away from the ring designed to fix the tenon to the ring at a sufficient distance from the ring to enable insertion of the tenon in the interstice.</p> |
