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.

A movable post device for supporting portions of flexible hose or cable members or the like, comprising: an elongated hollow sleeve having an outside diameter which is substantially uniform and a small fraction of the length thereof, fulcrum means on one end of said sleeve defining an annular fulcrum edge having a diameter substantially larger than said outside diameter of said sleeve, means adjacent the other end of said sleeve for support of a flexible member to be supported, base means having an annular portion engageable by said annular fulcrum edge, an elongated coiled spring for acting between said base means and said sleeve to urge said annular edge into engagement with an annular portion of said base means and to hold said sleeve in a normal position while allowing pivotal movement of said sleeve about a fulcrum point on said annular fulcrum edge in response to application of a transverse force of a certain magnitude at said other end of said sleeve, first connection means between said spring means and said base means, and second connection means between said spring means and said sleeve, said spring being located substantially entirely within said sleeve and having a large number of convolutions and a diameter only slightly less than the inside diameter of said sleeve and being formed of a wire having a diameter which is relatively large in comparison to the inside diameter of said sleeve, said first connection means comprising a link, a first connection between one end of said link and said base means, and a second connection between the opposite end of said link and said spring, said link being effective to minimize transverse displacement of said second connection and to minimize pressure engagement between convolutions of said spring and the internal surface of said sleeve.
