Abstract
A key ring apparatus is designed to provide visual evidence of tampering. The key ring apparatus includes a main loop member having adjacent end portions with substantially equal diameters. The key ring apparatus also includes a hollow tubular sleeve that receives the main loop end portions, and is crimped into place thereon after keys have been placed on the main loop member. The tubular sleeve may have a pair of crimping indication indicators thereon, to show where to crimp the sleeve onto the main loop of the key ring apparatus. One or both of the main loop member and the sleeve may have a unique serial identification number thereon.
Claims20
A key ring apparatus configured to provide visual evidence of tampering in the event that tampering occurs, said key ring apparatus comprising:
- a main loop member including a first end portion having a first diameter and a second end portion for placement adjacent to the first end portion with an open space therebetween, the second end portion having a diameter which is substantially equal to the first diameter, each of said first and second end portions having a respective groove formed circumferentially therein and a respective sleeve alignment indicator thereon adjacent the groove;
- and
- a tubular sleeve member having a hollow passage formed therethrough to receive the end portions of the main loop member, said tubular sleeve member having a pair of spaced-apart crimping location indicators thereon to suggest crimping areas for applying a crimping tool thereto;
- wherein when the sleeve member is slidably installed on the main loop member, the ends of the sleeve member are alignable with the sleeve alignment indicators to correspondingly align the crimping location indicators of the sleeve member with the underlying grooves of the main loop member.

A key ring apparatus configured to provide visual evidence of tampering in the event that tampering occurs, said key ring apparatus comprising:
- a main loop member formed from a substantially rigid material, the main loop member including a first end portion having a first diameter and a second end portion disposed adjacent to the first end portion with an open space therebetween, the second end portion having a diameter which is substantially equal to the first diameter, each of said first and second end portions having a respective groove formed circumferentially therein, and each of said first and second end portions having a sleeve alignment indicator formed circumferentially therearound adjacent the groove for guiding a user in aligning the sleeve and the main loop member;
- and
- a tubular sleeve member having a hollow passage formed therethrough to receive the end portions of the main loop member, said tubular sleeve member having a pair of spaced-apart crimping location indicators thereon to suggest crimping areas for applying a crimping tool thereto;
- wherein when the sleeve member is slidably installed on the main loop member, the ends of the sleeve member are alignable with the sleeve alignment indicators to correspondingly align the crimping location indicators of the sleeve member with the underlying grooves of the main loop member.

A method of fixing a key on a key ring apparatus configured to provide visual evidence of tampering, said method comprising the steps of:
- a) mounting a key on a main loop member formed from a substantially rigid material, said main loop member including a first end portion having a first diameter and a second end portion disposed adjacent to the first end portion with an open space therebetween, said second end portion having a diameter which is substantially equal to the first diameter, each of said first and second end portions having a respective groove formed therein;
- b) sliding a tubular sleeve member having a hollow passage formed therethrough on to one of said first and second end portions of said main loop member, and slidably moving said sleeve member away from said open space between the end portions of the main loop member, said tubular sleeve having a pair of crimping location indicators thereon to suggest crimping areas for applying a crimping tool thereto;
- c) slidably moving said sleeve member to cover the end portions of the main loop member and to align the ends of the sleeve member with alignment marks formed on the first and second end portions of the main loop member adjacent the grooves, and thereby align the indicators of the sleeve member with the underlying grooves of the main loop member;
- d) making a respective indentation in each area of the sleeve member having a crimping location indicator thereon;
- and
- e) pressing a first of said indentations toward a corresponding groove formed in the first end portion of the main loop member, and pressing a second of said indentations toward a corresponding groove formed in the second end portion of the main loop member, in order to firmly connect the sleeve member to the main loop member so that at least one area of the key ring apparatus will be visually marked by any subsequent separation of the sleeve member from either of the two end portions.

A kit for use in fabricating a key ring apparatus configured to provide visual evidence of tampering in the event that tampering occurs, said kit comprising:
- a main loop member including a first end portion having a first diameter and a second end portion for placement adjacent to the first end portion with an open space therebetween, the second end portion having a diameter which is substantially equal to the first diameter, each of said first and second end portions having a respective groove formed circumferentially therein and a respective sleeve alignment indicator thereon adjacent the groove;
- and
- a tubular sleeve member having a hollow passage formed therethrough to receive the end portions of the main loop member, said tubular sleeve member having a pair of spaced-apart crimping location indicators thereon to suggest crimping areas for applying a crimping tool thereto;
- wherein the tubular sleeve member is separate from the main loop member;
- and wherein when the sleeve member is slidably installed on the main loop member, the ends of the sleeve member are alignable with the alignment marks to correspondingly align the indicators of the sleeve member with the underlying grooves of the main loop member.
