Perhaps the most common and dependable device for carrying keys is a split key ring. This device provides almost two turns of spring steel (“split key ring components”) of rigid metal that are wound so that a pair of end segments are spring-pressed against a center segment, with the end segments terminating in ends where keys enter and leave the ring. Although keys are very securely retained by such a key ring, this very security makes moving keys on and off very difficult since the tightly wound turns of the ring must be spread apart far enough to allow passage of a key.
Typically, a user may attempt to use the head of a key itself by wedging it between one of the ends and the center segment of a split key ring. Failing with this, or alternatively, one may attempt to spread the key ring apart by inserting a finger nail between the end and the center segment, possibly breaking the finger nail or hurting the finger. If there are many keys on the ring, or if other items such as a pocket knife are carried on the ring, the bulk of keys and other items may add resistance to spreading the segments of the key ring. This problem of adding and removing keys is realized by anyone who carries keys, but it is especially annoying to those who regularly use keys in their daily work, such as those who work in the maintenance and security trades.
Others have recognized the problem of opening a key ring as described above. As might be expected, the prior efforts have involved some type of device or implement for wedging and spreading the segments of the key ring apart.
Several devices which exist in the prior art are made of plastic which lacks strength or contain bulky components and designs which are difficult to manipulate with one hand.
It is desirable to have a key ring separator which easily opens split key rings with a single hand and which is designed to open a split key ring using minimal force or leverage.
It is further desirable to have a key ring separator which is compact and does not add bulk to a key ring. Key ring separators in the prior art add bulk to a ring already full of keys and are not as simple to use as might be desired.
Finally, it is desirable to have a key ring separator which can be used to add or remove any key on a ring without taking other keys off the ring.

For the purpose of promoting an understanding of the present invention, references are made in the text hereof to embodiments of an optimized key ring separator, only some of which are depicted in the figures. It should nevertheless be understood that no limitations on the scope of the invention are thereby intended. One of ordinary skill in the art will readily appreciate that modifications such as the dimensions, size, and shape of the components, alternate but functionally similar locations, and the inclusion of additional elements are deemed readily apparent and obvious to one of ordinary skill in the art, and all equivalent relationships to those illustrated in the drawings and described in the written description do not depart from the spirit and scope of the present invention. Some of these possible modifications are mentioned in the following description. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a representative basis for teaching one of ordinary skill in the art to employ the present invention in virtually any appropriately detailed apparatus or manner.
It should be understood that the drawings are not necessarily to scale; instead, emphasis is being placed upon illustrating the principles of the invention. In addition, in the embodiments depicted herein, like reference numerals in the various drawings refer to identical or near identical structural elements.
Moreover, the term “substantially” or “approximately” as used herein may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related.
An optimized key ring separator for spreading apart the adjacent end and intermediate portions of a split key ring that are spring-urged against each other along the inner surfaces of the split key ring components but are spreadable to allow a key to be placed on or taken off the ring is disclosed herein. The optimized key ring separator is adapted to encircle a key ring in the same way as a key and will remain on the key ring along with the keys and will not come off of the key ring while it is being used to insert or remove a key from the key ring. The optimized key ring separator includes a flange attached to an enclosed or unenclosed mounting portion. The gripping edge of the optimized key ring separator makes it easy to grip the key ring separator and wedge the flange between adjacent segments of the key ring spreading the segments apart.
This purpose of this invention is to facilitate the spreading apart of the segments of a key ring so that keys can be added to or removed from the key ring. The key ring separator is easily attached and removed from a key ring, and may include attachment components such as a string, a wire, a clip, a tether, a clasp or other attachment device.
The dimensions of the flange are experimentally designed to spread apart the segments of a key ring while the key ring separator remains on the key ring. The flange is mounted on a mounting component which may have special gripping edges. Some embodiments of a key ring separator may have flattened edges which allow for easy gripping. A serrated and/or flattened gripping edge may facilitate use of the key ring separator.
The key ring separator spreads apart the segments of a key ring and then provides a gap through which a key can pass, as the key ring separator, followed by the key, are slid around the key ring either to be placed on the ring or to be removed from the ring.
The key ring separator is thus able to leverage the segments of a key ring apart by rolling the separator between the fingers of one hand using an optimally designed flange made of a material providing optimum leverage.
The key ring separator disclosed herein is compact and lightweight and can be carried on a key ring with keys and other items thereon while occupying a minimum amount of space on the ring and in a user's pocket, purse or other area used for storing keys. It is also easy and inexpensive to manufacture through extrusion and/or other mass production processes.
