The pivot control mechanism that selectively controls the rotation of the pivot control shaft by an electric impulse from the solenoid, which locks the pawl into the ratchet, thereby permitting the shaft to rotate in a selected direction. When a passage direction is chosen, the cam followers move out of the home position of the lofted ratchet over the peak position to the next home position. The guiding pins controlling the axial motion of the lofted ratchet in conjunction with the compression springs secure the cam followers in the home position. The shock absorber acting on the cam is used to prevent the turnstile from over rotating with any great amount of force, hence softening the return of the cam followers to the home position. The micro switch is activated, sending a signal to the control board, which through the action of the solenoid, locks the pawls into the ratchet.
A pivot control mechanism construction adapted to electronically facilitate the selective passage between two defined areas, said pivot control mechanism comprising of
The pivot control mechanism locking member comprising of a rigid pawl having an obtuse angle, this said pawl also includes a means for cooperating with a suitable associated tool in order to allow said pawl to be rotated.
The pivot control mechanism further comprising of a lofted ratchet of a cylindrical shape and
The pivot control mechanism further comprising of a middle plate engagement of the lofted ratchet for further pressure adjustment on the said lofted ratchet.
The pivot control mechanism further comprising of guiding rods thereby controlling the axial motion of the lofted ratchet.
The pivot control mechanism further comprising of compression springs acting on the lofted ratchet thereby securing said mechanism in the home position.
The pivot control mechanism further comprising of a cam and ratchet having been made from of one piece of material.
The pivot control mechanism further comprising of the pin inside the slider body which keeps the shock cam follower on the shock rod in full contact with the cam surface.
The pivot control mechanism further comprising of a shaft with shoulder screws securing cam followers equidistantly on the circumference
The pivot control mechanism construction is adaptable to any existing turnstile structure due to its size and configuration
