Movable support post devices are provided in which portions of flexible hose or cable members are supported from the upper end of a post structure including an elongated sleeve and a foot member which has a smaller diameter portion crimped on the lower end of the sleeve and a larger diameter portion defining a fulcrum edge which is engaged with a base member. In one embodiment a coiled tension spring is disposed within the sleeve with its upper end being connected to the sleeve and with its lower end being connected through a link to a base member, the link serving to minimize binding actions and stresses. In another embodiment, a coiled compression spring is disposed within the sleeve, the lower end of the spring being retained by a washer at the crimped end of the sleeve and the upper end of the spring being coupled to a retainer key and to the upper end of a tension rod, the lower end of which is hooked to the base member. In still another embodiment, using a compression spring and tension rod, the lower end of the tension rod is connected to the base member through a link. |
