A positioning pole (10) comprising an elongated center pole (20), a first guide (21) disposed on an outer surface of the center pole (20), a first support leg (50), and a first attachment coupler (60) which pivotally attaches the first support leg (50) to the first guide (21). The first guide (21) has an elongated dimension oriented parallel to the elongated dimension of the pole (10). The first attachment coupler (60) has an elongated dimension oriented parallel to the elongated dimension of the guide (21), a first face (61), and a second face (62). The first face (61) of the first attachment coupler (60) has a contoured surface interfitting with the pole's first guide (21) and enables the first attachment coupler (60) to slide along the elongated dimension of the first guide (21) without separating from the guide in directions that are perpendicular to the guide's elongated dimension. A locking mechanism (80) locks the attachment coupler (60) to a corresponding guide once a desired position is found for the support leg (50). |
