Alarmed cable lock
First Claim
1. An alarmed cable lock comprising:
- a) a channel closed at one end;
b) a cable having at least one free end, the free end including a terminus that cooperates with the channel to secure the free end to the channel;
c) a blocking pin capable of preventing the free end of the cable from being removed from the open end of the channel;
d) a switch exposed to the channel, interposed between the closed end of the channel and the blocking pin; and
e) a security system in electrical connection with the switch such that if the terminus of the cable is passed over the switch, the security system emits an audible sound.

Abstract
An alarmed cable lock that sounds an alarm upon an attempt to open the lock or remove the secured item while the alarm is armed. The invention includes a lock, a cable, a power source and an alarm. The lock includes a C-channel closed at one end, a switch, and a blocking pin. The cable is attached at one end to the lock. The free end of the cable terminates in a head that is formed to slide in the C-channel. The switch is exposed in the C-channel. When the lock is armed, the blocking pin extends into the C-channel to prevent the free end of the cable from sliding out of the open C-channel end. If an attempt is made to remove the end of the cable by sliding it out the C-channel, the head passes by the switch and sets off the alarm. The alarm/lock features are operated by remote control.
