Definitions

  • the present invention relates to ring buckle technology and more particularly, to a dual-entry keyring for receiving and keeping keys together.
  • 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.
  • US 2,410,951 A discloses a key ring and the like of the general type indicated and wherein the ends of the ring may be caused to spread apart or outwardly from close relation with the mid-portion of the ring on squeezing toward one another of spread portions of the ring located at the side of the letter diametrically opposite side that ends.
  • 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.
  • 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.
  • 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.
  • the dual-entry keyring comprises a ring body 1.
  • the ring body 1 exhibits a two-turn ring shape design.
  • the ring body 1 is made from a rigid material in a spiral form.
  • the ring body 1 comprises a first end 11 and a second end 12 respectively disposed at opposing top and bottom sides thereof beyond superimposition.
  • the ring body 1 further comprises a first press portion 13 and a second press portion 14 arranged between the first end 11 and the second end 12 to face toward each other, and respectively outwardly curved so that a gap 15 is defined between the first press portion 13 and the second press portion 14.
  • first end 11 and the first press portion 13 are formed in one turn, namely, the first turn of the two-turn ring shape design of the ring body 1
  • the second end 12 and the second press portion 14 are formed in the other turn, namely, the second turn of the two-turn ring shape design of the ring body 1.
  • the part of the first turn of the two-turn ring shape design of the ring body 1 beyond the first press portion 13 is closely abutted to the part of the second turn of the two-turn ring shape design of the ring body 1 beyond the second press portion 14 so that a stress point 16 is formed at each of two opposite lateral sides of the gap 15 between the first press portion 13 and the second press portion 14.
  • the first press portion 13 is on the same plane as the first end 11
  • the second press portion 14 is on the same plane as the second end 12.
  • each stress point 16 works as the fulcrum to carry out a lever-principle experiment, causing the first end 11 and the second end 12 to tilt up at the same time, causing the ring body 1 to provide an entry for allowing a ring hole 101 of a key 100 to be selectively attached onto the first end 11 or the second end 12 and then moved to the first press portion 13 through 180° maximum (i.e., half turn of the two-turn ring shape design of the ring body 1 ), and thus, the key 100 is held in the ring body 1, as illustrated in FIG. 4 .
  • the keyring structure of the present invention is convenient in use and still retains its durability for keeping keys.
  • FIG. 5 illustrates another application example of the present invention.
  • the dual-entry keyring When using the dual-entry keyring to hold a key 100, insert the key 100 into the gap 15 in a parallel manner relative to the ring body 1, and then move the key 100 along the ring body 1 in the arrowhead direction as illustrated in the drawing through 180°.
  • the body of the key 100 stretches open the double layer structure of the ring body 1.
  • the key 100 reaches, for example, the first end 11, the first end 11 is tiled up for allowing the ring hole 101 of a key 100 to be attached onto the first end 11.
  • the user can attach the key 100 onto the first end 11 or second end 12 without pressing the first press portion 13 and the second press portion 14.
