Abstract
An electronically controlled solenoid lock mechanism that remains locked when subjected to an impact type force. The lock utilizes the kinetic energy of a sliding bar during an impact to push on a lever with a fixed fulcrum such that the opposite end of the lever pushes against the core of the solenoid to keep it engaged with a latching mechanism. This prevents the unintentional opening a device to which the lock is attached with a mechanism that is energy, weight and cost efficient.
Claims4
An impact resistant solenoid lock mechanism comprising:
- a. a moveable latch means,
- b. a fixed, electronically controlled, electromagnetic solenoid containing a ferrous core with a collar means on said core and a return spring capable of exerting a force on said core,
- c. a bar with a collar means capable of freely sliding between two fixed points,
- d. a lever means with a fixed fulcrum mounted between said solenoid and said bar,
- whereby the kinetic energy of said bar during an impact acts on said lever, which in turn, acts on said core to prevent disengagement of said latch.
