In U.S. Pat. No. 5,136,858, (Bruner), which is hereinafter referred to as the '858 patent and of which I am the sole inventor, and the disclosure of which is incorporated herein by reference, there is disclosed and claimed an openable ring which overcomes many of the drawbacks of the prior art openable rings. In particular, the openable ring of the '858
One advantage the '858 openable ring has over the prior art is that it is not susceptible to inadvertent opening.

It is a more specific object of this invention to provide an openable ring construction having a safety latch construction which is not susceptible to inadvertent opening.
Page 8:
It should be noted that the force biasing the safety latch into a closed position, resulting from the engagement of tongue 64 with the projecting section 116, is continuously maintained during a portion of the counterclockwise rotational movement of the safety latch in the direction of arrow 134 (FIG. 3). This arrangement precludes inadvertent opening of the safety latch 62, in that any "slight", inadvertent, counterclockwise movement of the safety latch, in the direction of arrow 134, will not automatically open the safety latch. In fact, once the pressure or force is released, the normal spring tension imposed upon the projecting section 116, by the tongue 64 will automatically snap the safety latch back into its locking position. In other words, the cam arrangement provided by the interaction of the tongue 64 with the projection 116 will trigger an opening action at a depth of counterclockwise rotation, which only can be reached by the use of a separate implement, such as a pen or pencil, as will be described hereinafter. |
