Abstract:
A lock includes a housing, a cylindrical core body and a tumbler unit. The core body is rotatably mounted in the housing, and includes a core axle, and a core tube sleeved on the core axle. The core axle has a helical keyway. The tumbler unit includes a housing pin hole formed in the housing, a tube through hole formed through the core tube, a pin assembly movably mounted in the housing pin hole and the tube through hole, a hole-defining surface defining the tube through hole and having a shoulder surface portion, and a resilient member disposed in the housing and resiliently biasing the pin assembly to abut against the shoulder surface portion and extend into the helical keyway.

Claim (Index 7):
A key adapted to be used with the lock in  claim 1 , comprising:\n a grip section for being held; and a blade section connected to said grip section, said blade section including at least one helical blade that extends about a key axis of said key, said at least one helical blade being adapted to correspond in shape to the helical keyway of the lock, and having at least one recess that is formed in an outer helical surface thereof, said recess of said at least one helical blade being adapted to be engaged with the pin assembly of the lock when said at least one helical blade is inserted into the helical keyway of the lock, wherein said blade section includes a plurality of helical blades, each of said helical blades being adapted to correspond in shape to a respective one of the helical keyways of the lock, and having at least one recess that is formed in an outer helical surface thereof, said at least one recess of each of said helical blades serving as a coplanar recess, said coplanar recesses of said helical blades residing in a second plane that is perpendicular to the key axis, said coplanar recesses of said helical blades being adapted to be respectively engaged with the pin assemblies of the coplanar tumbler units of the lock when said helical blades are respectively inserted into the helical keyways of the lock.
