BACKGROUND OF THE INVENTION

1. Field of the Invention.

[0002] This invention generally relates to keys, and to devices for holding keys.

2. Related Art.

[0003] Keys for locks have been ubiquitous for centuries. Many types of devices for holding keys have been developed that use rings, clips, chains, wallets, enclosures, and other structures to join keys together. In spite of all of the work that has been done to provide devices that organize keys for storage and convenient access, many people still tend to either mount their keys on a simple key ring, or use a wallet having rings for mounting keys. Both of these two types of key holding devices are generally perceived as disorganized and cumbersome. Meanwhile, keys generally have a chaotic variety of shapes and sizes, further contributing to the disorganization of a typical person's keys. A continuing need exists for standardized keys, and for a device for holding keys that facilitates organization of an end user's keys for secure storage and convenient use.

[00139] The key organizing devices 100, 2100, 3600, 3800, 4000 may be fabricated from materials selected for suitable durability, functionality and appearance of the key organizing devices 100, 2100, 3600, 3800, 4000. For example, the housing 204, 2102, 3604, 3804, 4004 may be formed of a plastic, metal, or graphite material. As a plastic material, Lustran® 248 acrylonitrile-butadiene-styrene ("ABS") may for example be utilized in forming the housings

204, 2102, 3604, 3804, 4004. An indicia plate 326 may be formed of the same material selected for the housing 204, 2102, 3604, 3804, 4004. Where the cover 104, 2104, 3606, 3802, 4002 of a key organizing device 100, 2100, 3600, 3800, 4000 includes tabs 2008, 4008, the cover 104, 2104, 3606, 3802, 4002 may be formed of a flexible material such as a plastic composition. Likewise, where the housing 204, 2102, 3604, 3804, 4004 of a key organizing device 100, 2100, 3600, 3800, 4000 includes tabs 2008, 4008, the housing 204, 2102, 3604, 3804, 4004 may be formed of a flexible material such as a plastic composition. Where the cover 104, 2104, 3606, 3802, 4002 or housing 204, 2102, 3604, 3804, 4004 does not include tabs 2008, 4008, then that cover 104, 2104, 3606, 3802, 4002 or housing 204, 2102, 3604, 3804, 4004 may instead be formed of a minimally-flexible material such as a metal composition. As an example of a metal composition, aluminum alloy 380 may be die-cast and utilized. The sliders 106, 2600, 3200 may be formed, for example, from a flexible material such as a plastic composition. As an example, DuP ont Delrin IOOT ® may be utilized. The keys 320, 800, 2800, 4200, 4600 may, for example, be formed of a metal alloy. CDA 353 brass is an example of a suitable metal alloy for forming keys 320, 800, 2800, 4200, 4600. A slider dampener 2216, 2316, in a key organizing device 100, 2100, 3600, 3800, 4000 may be formed from a material having suitable flexibility and durability for frequent deformation as sliders 106, 2600, 3200 are deployed. For example, a polyurethane foam having Shore Durometer 5OA +/- 5 hardness may be utilized in forming a slider dampener 2216, 2316. A key dampener 1706 in a key organizing device 100, 2100, 3600, 3800, 4000 may be formed from a material having suitable flexibility and durability for frequent sliding engagement with keys 320, 800, 2800, 4200, 4600 as sliders 106, 2600, 3200 are deployed. As an example, Poron Quick-Recovery super-resilient open cell polyurethane foam, having a firmness of 8-14 pounds per square inch, a density of 15 pounds per cubic foot, a 100% stretch limit, and a tensile strength of 80 pounds per square inch may be utilized. Pins 3508 in sliders may be formed, for example, of a metal alloy such as 303 stainless steel. Exterior surfaces of key organizing devices 100, 2100, 3600, 3800, 4000 may have decorative surfaces, such as multiple-colored first and second housing elements 308, 310 for example. [00140] Dimensions for the key organizing devices 100, 2100, 3600, 3800, 4000 and keys 320, 800, 2800, 4200, 4600 may be selected consistent with factors including utility and portability, as well as standardization. For example, key organizing devices 100, 2100, 3600, 3800, 4000 may be selected to hold six (6) keys 320, 800, 2800 4200, 4600, including three (3) keys 320, 800, 2800, 4200, 4600 having finger pads 402, 2602, 3202 exposed outside each of

first and second housing elements 308, 310, 2108, 2110. Key organizing devices 100, 2100, 3600, 3800, 4000 configured with other arrangements of finger pads 402, 2602, 3202 and configured for holding different quantities of keys 320, 800, 2800, 4200, 4600 may also be fabricated. For example, a key organizing device 100, 2100, 3600, 3800, 4000 configured for holding six (6) keys 320, 800, 2800, 4200, 4600 may have overall dimensions including a width of about 1.17 inches, a height of about 0.67 inches, and a length of about 2.75 inches. Key slots 2002 may be, for example, about 1.0 inch tall and about 0.45 inch wide. Keys 320, 800, 2800, 4200, 4600 may, for example, be standardized with blades 902 having a thickness yyy within a range of between about 0.07 inch and about 0.10 inch, key heads 1002 having a width zzz of about 0.44 inch, and key head edges 906 having a thickness of about 0.1 inch. Keys 320, 800, 2800, 4200, 4600 and key organizing devices 100, 2100, 3600, 3800, 4000 may be mutually configured, for example, to provide a standardized deployment length for a key blade 902 in an extended position, such as about 1.9 inches. A key blade deployment length of 1.9 inches may provide at least about one-eighth of an inch of clearance between the key organizing device 100, 2100, 3600, 3800, 4000 and a lock (not shown) when a key 320, 800, 2800, 4200, 4600 is in use, to prevent scratching of the lock.

[00141] Keys 320, 800, 2800, 4200, 4600 may be configured for a wide variety of types of end-utilization, for example as keys 320, 800, 2800, 4200, 4600 for a vehicle, mailbox, deadbolt, house, office, or security lock. The key organizing device 100, 2100, 3600, 3800, 4000 may, for example, be utilized for holding a plurality of end-user selected keys 320, 800, 2800, 4200, 4600 or other implements configured for attachment into the key organizing device 100, 2100, 3600, 3800, 4000, such as a bottle opener, pen, knife, file, radio frequency identification fob, or bar code fob. Likewise, the keys 320, 800, 2800, 4200, 4600 may be configured for end-utilization in a wide variety of types of locks, or for holding non-key implements. While the foregoing description refers in some instances to the key organizing deviceslOO, 2100, 3600, 3800, 4000, and the keys 320, 800, 2800, 4200, 4600 as shown in the figures, it is appreciated that the subject matter is not limited to these structures, nor to the structures discussed in the specification. Other shapes and configurations of key organizing devices and keys may be fabricated.
