Keyless lock

A keyless lock which eliminates the requirement for visual contact with the lock to effect disengagement thereof comprising:

• a casing
• a shackle with a portion thereof extending into the casing and having a locking notch formed therein,
• at least one locking bar adapted to engage the locking notch of the shackle to lock the shackle within the casing,
• means to release the locking bar from engagement with the locking notch thereby permitting movement of the shackle out of the casing formed by:
• a forked member having one end engaging the locking bar to prevent movement thereof when in the locked position,
• a plurality of pins on the forked member opposite the end engaging the locking bar,
• a plurality of ratchet wheels, each ratchet wheel having a slot formed therein, the ratchet wheels being adapted to rotate incrementally,
• means to position the ratchet wheels in an initial reference position,
• push button means associated with each ratchet wheel, and being connected to a first pawl which engages and rotationally drives the ratchet wheel from its initial reference position to an incremented rotated position,
• each push-button means having a predetermined numerical code to increment its respective ratchet wheel to a slot and pin alignment position,
• whereby the lock can be opened without visual contact by pushing each push-button means the predetermined numerical code number to align each slot with its respective pin on the forked member, and pulling on the shackle which in turn causes the locking bar to exert a force on the forked member thereby causing the pins on the forked member to be forced into and received by the aligned slots on the ratchet wheel, permitting movement of the locking bar and releasing the shackle.
