ABSTRACT:
A turnstile structure has a control head contained in a readily accessible head compartment assembly. The head compartment assembly contains the control head in a cavity within the assembly and the turnstile control assembly, e.g., turnstile arms, extend outwardly from the control head and away from the head compartment. The head compartment assembly is fastened to a turnstile structure main frame at two principle edges of the assembly. Along one of these principle edges, the head compartment assembly is hinged to the main frame. At the other principle edge, the head compartment assembly is releasably secured to the main frame. These connections can provide for access to the control head through either tilting the head compartment assembly upwardly to expose the assembly cavity, in one structural embodiment, or downwardly to expose the cavity in another structural embodiment. The novel head compartment assembly is useful in not only preparing newly made turnstile structures, but also in refurbishing existing structures. The turnstile may also be equipped with a novel base plate, in addition to the novel head compartment assembly.
