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.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to ring buckle technology and more particularly, to a dual-entry keyring for receiving and keeping keys together.

2. Description of the Related Art

As life is getting more and more convenient, people commonly carry a number of keys, including gate key, door key, vehicle key, office key, and other types of keys. To facilitate arrangement and use, people usually will use a keyring to keep keys together.

To meet such convenience, a variety of keyring and keychain designs of different types of structure and material or different key mounting measures have been created and have appeared on the market. However, to secure the keys most keyrings are made relatively stiff and therefore hard to open, i.e. putting on a key may be rather cumbersome. Moreover, the stiffness may lead to nails breaking when attempting to open up a keyring. U.S. Pat. No. 8,464,564 discloses an elegant and cost-efficient design that solves the above-mentioned problem.

According to U.S. Pat. No. 8,464,564, the keyring comprises a wire arranged in at least two rounds providing a resilient spiral. The spiral has a first and a second end, wherein the first end by means of inertial resiliency is forced to tightly contact a first surface of a lower round and the second end is forced to tightly contact a second surface of an upper round wherein at least one end is openable, by means of arranging a peak providing a compressible gap between the at least two rounds. This keyring design is functional, however, it is rather complex and inconvenient in use.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a dual-entry keyring of high durability and cost-effectiveness, which utilizes the principle of lever for allowing a key to be easily attached onto one of two opposite ends thereof and then turned into the inside of the ring body of the keyring through 180° angle with less effort.

To achieve this and other objects of the present invention, a dual-entry keyring comprises a ring body in a two-turn ring shape design. The ring body comprises 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 with a gap defined therebetween. 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring toFIGS. 1 and 2, a dual-entry keyring in accordance with the present invention is shown. The dual-entry keyring comprises a ring body1. In this embodiment, the ring body1exhibits a two-turn ring shape design. The ring body1is made from a rigid material in a spiral form. In this embodiment, the ring body1comprises a first end11and a second end12respectively disposed at opposing top and bottom sides thereof beyond superimposition. The ring body1further comprises a first press portion13and a second press portion14arranged between the first end11and the second end12to face toward each other, and respectively outwardly curved so that a gap15is defined between the first press portion13and the second press portion14. Further, the first end11and the first press portion13are formed in one turn, namely, the first turn of the two-turn ring shape design of the ring body1, the second end12and the second press portion14are formed in the other turn, namely, the second turn of the two-turn ring shape design of the ring body1. The part of the first turn of the two-turn ring shape design of the ring body1beyond the first press portion13is closely abutted to the part of the second turn of the two-turn ring shape design of the ring body1beyond the second press portion14so that a stress point16is formed at each of two opposite lateral sides of the gap15between the first press portion13and the second press portion14. In this embodiment, as illustrated inFIG. 2, the first press portion13is on the same plane as the first end11; the second press portion14is on the same plane as the second end12.

Referring toFIG. 3, when using the dual-entry keyring, apply a pressure to the first press portion13and the second press portion14to compress the gap15. At this time, each stress point16works as the fulcrum to carry out a lever-principle experiment, causing the first end11and the second end12to tilt up at the same time, causing the ring body1to provide an entry for allowing a ring hole101of a key100to be selectively attached onto the first end11or the second end12and then moved to the first press portion13through 180° maximum (i.e., half turn of the two-turn ring shape design of the ring body1), and thus, the key100is held in the ring body1, as illustrated inFIG. 4. Thus, the keyring structure of the present invention is convenient in use and still retains its durability for keeping keys.

FIG. 5illustrates another application example of the present invention. When using the dual-entry keyring to hold a key100, insert the key100into the gap15in a parallel manner relative to the ring body1, and then move the key100along the ring body1in the arrowhead direction as illustrated in the drawing through 180°. In the movement of the key100toward the first end11or second end12, the body of the key100stretches open the double layer structure of the ring body1. As soon as the key100reaches, for example, the first end11, the first end11is tiled up for allowing the ring hole101of a key100to be attached onto the first end11. Thus, according to this second application example, the user can attach the key100onto the first end11or second end12without pressing the first press portion13and the second press portion14.
