Costly devices are supported atop telescopically extensible masts of theft resistant mounts well suited to be positioned at temporary, often unattended, outdoor locations. An upper component of each mast carries a torque-disconnect coupler that has two relatively turnable elements, including one fixed to the mast, and another that defines a threaded formation extending along an upstanding axis about which the elements are relatively turnable. A costly device can be tightened to the threaded formation, or can be loosened and removed therefrom—but only when an elongate key-like tool is inserted into aligned passages of the two elements to prevent turning of the threaded formation so a costly device tightened onto the formation can be threaded off of the formation. A shroud cloaks the torque-disconnect coupler and has an opening through which the tool must pass to reach the aligned passages. |

1. A theft resistant mount for adjustably supporting at temporary outdoor locations a costly device likely to be a target for theft, comprising:
a) a roadway barrier segment that is impossible for one person to manually carry due to at least a selected one of the weight and the size of the barrier segment, with the barrier segment including a base positionable on a generally upwardly facing support surface, and an elongate mast connected to the base and being capable of extending upwardly from the base to a selection of heights; b) first and second elements of a bearing extending concentrically along an axis, and being capable of turning relative to each other about the axis unless and until an elongate tool is caused to extend concurrently into aligned first and second passages, with the first passage being defined by the first element, with the second passage being defined by the second element, with the first element surrounding the second element such that the first element covers the second passage to render the second passage inaccessible except through the first passage when the first and second passages are aligned, and with alignment of the first and second passages being achieved by turning at least one of the first and second elements about the axis relative to the other of the first and second elements; c) with the first element being fixed to the mast, with the second element defining a threaded formation extending along the axis, with the costly device being tightenable to and removable from the threaded formation when, and only when, the elongate tool is inserted into the aligned first and second passages to thereby substantially prevent turning of the threaded formation about the axis; d) a shroud that covers the first and second elements of the bearing such that the shroud at least partially cloaks from view an opening into the first passage, through which opening the elongate tool extends when the elongate tool is being inserted into the aligned first and second passages; and e) with the shroud including a generally cylindrical sidewall that encircles, at a distance spaced from, the first element of the bearing, and the generally cylindrical sidewall has a third passage extending therethrough that the elongate tool must extend through before the elongate tool can be inserted into the aligned first and second passages. |
