An anchoring structure for an annular member includes a housing including a first casing and a second casing, and the annular member. The annular member is partially interposed between the first casing and the second casing. The annular member includes an external member that protrudes to an outside of the housing, and an internal member connected to the external member and located on an inside of the housing. The first casing includes a first engagement portion into which a first end of the internal member is inserted, the first engagement portion limiting the first end from moving in a direction away from the first casing. The first casing includes a second engagement portion limiting a second end of the internal member from moving in the direction away from the first casing while the first end of the internal member is engaged with the first engagement portion.

A key ring for holding keys is described comprising of overlying loops formed from spring wire which both ends biased against the loops to prevent accidental loss of keys. A special portion is formed near the end of one loop to offset its edge from the underlying loop. This special portion allows for easy grasping and separation of the loops for adding or removing key to the key ring.

A lanyard fob having a fob and a lanyard. The fob having a front housing and a rear housing, wherein the front housing is configured to rotate about the rear housing, wherein the rear housing includes a first pocket and a second pocket. The lanyard having a first end and a second end, wherein the first pocket is configured to receive the first end and the second pocket is configured to receive the second end. The first end is permanently fixed within the first pocket and second end is configured to removably slide within the second pocket such that the lanyard fob is operable between an open position and closed position.

An automatic locking keychain includes a curved plate, a pin shaft at one end of the curved plate, a middle seat rotatably arranged on the pin shaft, a fitting block on the middle seat, and a locking mechanism on a side of the curved plate close to the pin shaft. An end side surface of the fitting block away from the middle seat is attached to another end of the curved plate. The locking mechanism is configured to limit a rotation of the middle seat, and includes a limiting hole at an end of the curved plate close to the pin shaft, a sliding rod sliding inside the limiting hole, and a locking shaft at an end of the sliding rod close to the pin shaft. A locking hole is arranged on the middle seat. A spring is provided between the sliding rod and the limiting hole.

This invention is directed toward a flat, washer-like key ring. In some embodiments, the key ring is substantially circular. It is distinct from prior art in that the key ring largely, or entirely, resides in a single plane, as opposed to being concentric circles overlapped one on top of the other. The key ring has a split line running through a portion of its body. The split line creates inner and outer segments along a portion of the plane of the body. The split line can be non-linear, in that it may not be a straight line. As such, the split line has protrusions and slots running along its length. These protrusions and slots interact mechanically to allow the key ring to remain securely closed, and endure greater radial forces, by coupling the inner and outer segments together. The inner and outer segments are also releasably attached so as to facilitate the addition or removal of a key.

A hand tool adapted to manipulate and open split rings is provided. The hand tool has two elements both having handles operatively associated so that the distal end jaw portions of the elements are movable between a closed and an open position. An opening jaw has a penetrating probe for opening convolution of a split ring, while the opposing supporting jaw provides a supporting surface acting as an anvil providing opposing force to the other linear elements probe. The split ring is generally disposed around the spaced apart opposing jaws, permitting the probe to penetrate the convolutions over a deeper range because there is no limitation created by the opposing jaw.

A lock ring includes an elongated body including an end having a male portion, including a tip having a transverse cross-section larger in diameter than an adjacent portion of the lock ring body. Another end of the body includes a female portion including a tip having a transverse cross-section larger in diameter than the tip of the male portion of the body. The tip of the female portion defines a groove open to the exterior of the tip of the female portion. The groove is configured for receiving the tip of the male portion of the body, wherein the ends of the body are in a connected position. A cover is configured for closing the groove in the tip of the female portion of the body for securing the male portion of the body in the female portion in the connected position.
