  • Patent number: 11903457
    Abstract: An integrally formed resilient holder is configured in the form of a two-turn spiral ring body with an elongated configuration. The holder includes an upper loop and a lower loop having a size substantially different from that of the upper loop, such that pivot points are created at which the upper loop and the lower loop intersect each other. In the light of its deformability, the holder can be easily triggered to open up an entry port through which keys or rings may be introduced or removed by a simple press from the user. The holder is of high durability and versatility and is cost-effectiveness accordingly.

  • Patent number: 10085522
    Abstract: A dual-entry keyring includes a ring body in a two-turn ring shape design, defining a first end and a second end respectively disposed at opposing top and bottom sides thereof beyond superimposition and a first press portion and a second press portion arranged between the first end and the second end to face toward each other and respectively outwardly curved so that a gap is defined between the first press portion and the second press portion. Further, the part of the first turn of the two-turn ring shape design of the ring body beyond the first press portion is closely abutted to the part of the second turn of the two-turn ring shape design of the ring body beyond the second press portion so that a stress point is formed at each of two opposite lateral sides of the gap between the first press portion and the second press portion.
