Quick opening child proof gun/medicine cabinet lock

Abstract

The lock can be used as a lock for an individual box, cabinet door or drawer where the objective is to keep guns, medicine, chemicals etc. secure from children. Only an individual whose finger it has been adjusted to can open the lock. The components of the lock include a machined hole where the finger is inserted which has a flanged front for attachment. The finger presses against a curved spring-loaded plate where the three tabs measure the thickness of the first three components of the index finger. (Corresponding to the three finger bones). The tabs are adjusted so when a downward and forward motion is made with the finger, the pins will align with the slots on the alignment plates and the lock will open. Thus the lock is as unique as the thickness and length of the individuals finger and due to the small size of a child's finger it is child proof.

1 . A quick opening child proof lock comprising a rectangular housing having a flanged front face which can be secured to a security box, drawer or cabinet so when the index finger is inserted a downward pressure is made, measurement confirmed and a forward pressure is applied the latch will release from a striker plate.  
     
     
         2 . The lock means of  claim 1  where in thickness measurements are taken by three tabs (FIG. 2 and FIG. 6) of the individuals first three bones of the finger to align the tamper proof pins.  
     
     
         3 . The lock means of  claim 1  where in said member has tamper proof pins attached to the tabs (FIG. 6) grooved so exact alignment must be achieved on all three pins or the sharp points of the pin three alignment plates (FIG. 5) will prevent engagement and the latch will not release.  
     
     
         4 . The lock means of  claim 1  where in said member has two tabs on top of the rectangular housing (FIG. 1) that are bent down at a slight angle and interfere with the sliding mechanism. The sliding mechanism must be pushed down to clear the two tabs before it can be pushed forward. This is part of the childproof and tamper proof feature of the lock.
