Pedestal Lock

       Disclosed is a mechanism for locking a pedestal lock.
The height of this mechanism is so reduced that it can be inserted in
the hemisphere of the pedestal.

      The prior pedestal is shown in Fig. 1.  In Fig. 1, the lock
member, the hemisphere and the base have teeth-shaped portions which
are engaged with each other.  The teeth-shaped portion of the
hemisphere is for adjusting the degree of the tilt of the pedestal,
and the teeth-shaped portion of the base are for the swivel position
of the pedestal.  When the lock member slides down, it clutches both
the hemisphere and the base at one time.  The lock member needs a
stroke for sliding, so the pedestal height is taller than the
pedestal which does not have the lock member.

      The improved pedestal is shown in Fig. 2.  Since the improved
pedestal has the cylindrical lock lever, its height is the same as
the pedestal which does not have the lock member.  When the lock
lever slides horizontally, it must push the lock vertically.  So the
cylindrical lock lever has two different radii.  The lock lever is
shown in Fig. 3.
