Abstract:
1. A gate closer post assembly, comprising: a hollow cylindrical post for vertical attachment to a floor; a pivotable shaft disposable inside and coaxial to the hollow cylindrical post, and supported internally by upper and lower bearings that enable a gate to be supported by a two-point attachment to the pivotable shaft and to allow said gate to hinge inside the post on a central axis; a parallel pair of lateral slots disposed in the hollow cylindrical post each correspondingly proximate to said two-point attachment, wherein a gate hung on the hollow cylindrical post and fixed to said two-point attachment to the pivotable shaft is permitted to swing between an open position and a closed position; a torsion spring attached to the pivotable shaft so as to oppose said gate from swinging open and to automatically return the gate to said closed position; an assembly of the pivotable shaft, said upper and lower bearings, and the torsion spring sized to fit and lock inside the hollow cylindrical post, and arranged to permit the insertion and withdrawal of the assembly as a single unit through an open top of the hollow cylindrical post; and a rotary dampener in a cylindrical housing sized to fit and lock inside the hollow cylindrical post, and having a shaft on a central axis with one outside bottom end mechanically keyed to engage a matching feature disposed on a top end of the pivotable shaft above the torsion spring and said upper and lower bearings; wherein, the rotary dampener limits a speed of automatic closure of said gate, and is removable through the top of the hollow cylindrical post without first demounting or disabling the functioning of said gate.
