Storage box alarm
First Claim
1. An alarm for a container including an enclosure defining an interior volume for holding tools or other belongings, a door adapted to move between an open position allowing access to the interior volume of the enclosure and a closed position for closing the enclosure, and a trip having a tripped condition and an untripped condition, the alarm comprising:
- a trip sensor operable between a first condition when the trip is in its untripped condition and a second condition when the trip is changed to its second condition; and
a circuit adapted to sense the condition of the trip sensor, the circuit being adapted to drive an output when the trip sensor is in its second condition.

Abstract
An alarm is provided for a container including an enclosure, a door, a door latch, and an actuator to open the latch. The alarm includes a switch, a circuit, and an output. The actuator actuates the switch when it opens the latch. In turn, the circuit senses the position of the switch and drives the output if the latch is open. Additionally, the alarm may include a power supply that powers the circuit via the switch when the latch is open. The alarm may also include a guide that prevents relative movement in one direction between the actuator and the switch. A lock switch may also be connected in series with the actuator switch so that the circuit drives the output only when the latch is open and the lock is locked. Additionally, a housing fitted to a lip of the enclosure may contain the circuit.

14. A container comprising:
-
an enclosure defining an interior volume for holding tools or other belongings;
a door adapted to move between an open position allowing access to the interior volume of the enclosure and a closed position for closing the enclosure;
a trip having a tripped condition and an untripped condition; and
an alarm comprising;
a trip sensor operable between a first condition when the trip is in its untripped condition and a second condition when the trip is changed to its second condition; and

26. A method of detecting unauthorized entry into a container including an enclosure defining an interior volume for holding tools or other belongings, a door adapted to move between an open position allowing access to the interior volume of the enclosure and a closed position for closing the enclosure, and a trip having a tripped condition and an untripped condition, the method comprising:
-
changing the trip from its untripped condition to its tripped condition;
sensing whether the trip is in the tripped position; and
triggering an alarm if the trip is in the tripped position. - View Dependent Claims (27, 28, 29, 30, 31, 32)

33. An alarm for a container including an enclosure defining an interior volume for holding tools or other belongings, a door adapted to move between an open position allowing access to the interior volume of the enclosure and a closed position for closing the enclosure, a latch moveable between a latched position to secure the door to the enclosure when the door is in its closed position and an unlatched position wherein relative movement of the door and enclosure is permitted, and an actuator operatively connected to the latch in a manner so that movement of the actuator from a first position to a second position causes the latch to move from its latched position to its unlatched position, the alarm comprising:
-
a power source;
a normally open actuator switch, the actuator adapted to close the actuator switch if the actuator moves from its first position to its second position, the actuator switch connected to the power source;
a circuit connected to the actuator switch to sense the position of the actuator switch by receiving power via the actuator switch; and
an output, the circuit to drive the output if the actuator switch is closed. - View Dependent Claims (34, 35)

36. An alarm for a container including an enclosure defining an interior volume for holding tools or other belongings, a door adapted to move between an open position allowing access to the interior volume of the enclosure and a closed position for closing the enclosure, a latch moveable between a latched position wherein the latch engages both the door and the enclosure in a manner to secure the door to the enclosure when the door is in its closed position and an unlatched position wherein relative movement of the door and enclosure is permitted, and an actuator operatively connected to the latch in a manner so that movement of the actuator from a first position to a second position causes the latch to move from its latched position to its unlatched position, the enclosure including a protrusion in the interior volume, the alarm comprising:
-
a housing with a recess adapted to mate with the protrusion;
an actuator switch adapted to move between a first position and a second position when the actuator moves between its first and second positions;
a circuit in the housing and adapted to sense the position of the actuator switch;
an output, the circuit to drive the output if the actuator switch is in its second position. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44)
