Abstract

A counting device includes a shaft, a handle affixed to a first end of the shaft, and a locking unit mounted in the handle spaced from the shaft. A locking plate has an opening for accommodating the shaft. The locking plate has a plurality of recesses facing the locking unit for cooperating with the locking unit. A position indicating assembly is coupled to the shaft to move as the handle is rotated. The recesses are arranged in a circular pattern on the locking plate such that the locking unit engages each recess as the handle is rotated around the shaft. The recesses are configured to permit one-way rotation of the handle.
