the cross sectional views of fig3 and 4 fig3 illustrates a keyless lock 20 in an unlocked position in which the locking bolt 70 is disposed entirely within the locking bolt housing 60 the second end of the connecting rod 55 is shown positioned within the locking bolt 70 cavity having a series of teeth 75 the ribs of the ribbed connecting rod 55 mate with the spaces between the teeth 75 thereby forming a gear in which the movement of the locking bolt 70 is caused by rotating the ribbed connecting rod 55 the connecting rod 55 is rotated via manipulation of the knob 25 i e turning the knob from a resting position when the connecting rod 55 is rotated in the direction of the arrow in fig3 the ribs of the connecting rod 55 grip the teeth 75 of the locking bolt 70 and the connecting rod 55 moves in the direction of the arrow while it urges the locking bolt 70 out of the locking bolt housing 60 as the locking bolt 70 is urged from the locking bolt housing 60 the locking bolt 70 is urged into the central bore 80 of the mounting plate 85 fig4 thereby locking the door to unlock the door the connecting rod 55 is rotated in the opposite direction and the movement of the locking bolt 70 is reversed.
