Abstract
This invention relates to a key ring, comprising a wire (2) arranged in at least two rounds (20,21,22) providing a resilient spiral (1), said spiral (1) having a first and a second end (23,24), wherein the first end (23) by means of inertial resiliency is forced to tightly contact a first surface (21 A) of a lower round (21) and the second end (24) is forced to tightly contact a second surface (20 B) of an upper round (20) wherein at least one end (23) is openable, by means of arranging a peak (3 A) providing a compressible gap (5) between said at least two rounds (20,21,22), wherein said wire (2) in at least one of the rounds, preferably all rounds, has a cross-section wherein the thickness (h) and width (w) is such that 2h<w<15h.
Claims13
A key ring comprising:
- a wire arranged in at least two rounds providing a resilient spiral, said spiral having 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 said at least two rounds, wherein said wire in at least one of the rounds has a cross-section wherein the thickness (h) and width (w) is such that 2h≦w≦15h, wherein the combination of the position of peak and the form of the wire is arranged to enable said first end to open up an insertion opening when compressing said gap, and not to enable said second end to open up an insertion opening.
A key ring comprising a wire arranged in at least two rounds providing a resilient spiral, said spiral having 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 said at least two rounds, wherein said wire in at least one of the rounds has a cross-section wherein the thickness (h) and width (w) is such that 2h≦w≦15h, wherein said peak creates a U-shaped gap between two adjacent rounds.
