Inventors:

Christopher Knapp - Murray UT, US
Jon McBride - Kaysville UT, US

International Classification:

A45F 5/00

US Classification:

224269000

Abstract:

Apparatus and methods for attaching a portable device to an object are described. The apparatus comprises a connector that can be used to connect a portable device (or an accessory thereof) to a retention mechanism that is retained to an object. As well, the connector can be used with a new type of attachment device by modifying that attachment device to accept the connector. Thus, the connector can be used with both the new attachment device and the conventional retention mechanisms.
