Abstract: Padlockable security collars are disclosed that each include a chain of elongate, in-series, hinge-connected components that are configured to cooperatively wrap and perimetrically shroud relatively movable elements of so-called “connection assemblies” and the like that have relatively movable members which need to be shrouded and protectively enclosed to prevent unauthorized operation. Holes that can be aligned to permit a shackle of a padlock to extend therethrough are formed through opposite end regions of each security collar's chain of components so the security collar can be locked in place once a compartment-defining component receives, shrouds and protectively encloses the relatively movable members that need to be prevented from being moved or operated while the security collar is locked in place.

Abstract: A telescopically extensible upstanding mast carries an upper mounting station near an upper end of the mast, a lower mounting station near the lower end of the mast, and an intermediate mounting station, located along the mast inbetween the lower and upper mounting stations, with each mounting station being independently lockable to releasably retain a separate costly equipment device. The upper mounting station has a threaded formation that is normally free-wheeling until a shrouded rotation control prevents the formation from turning so a costly equipment device can be threaded onto and off of the threaded formation. The intermediate and lower mounting stations each have removable and non-removable members that can be locked together to releasably retain costly equipment devices.

Abstract: 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.

Abstract: Theft resistant upstanding mounts adjustably support at temporary, often unattended outdoor locations, such costly devices as compact, wireless electronic devices that control such excavation machinery as bulldozers and road graders. Each mount is connectable to or includes a massive base structure, and includes an upstanding, telescopically extensible mast. Lockable connections are provided between many components of the mount. A lockable, swivel connection provided between the mast and a costly device supported atop the mast permits leveling of the costly device for proper operation even if a longitudinal axis of the upstanding mast deviates significantly from true vertical. A protective cover locked to the mast assembly denies access to a control knob that might otherwise be used to detach the costly device from the mast.

Abstract: A multipurpose sign base suitable for supporting temporary signs includes an upstanding mast supportable atop a support surface by a substantially horizontally extending, elongate, support member connected to a lower region of the mast, and by a plurality of elongate leg members of adjustable length each having an upper portion movably connected to a central region of the mast, and each having a lower portion movably connected to a different foot adapted to engage a different area of the support surface at locations arrayed about the mast. An upper region of the mast is connectable to a sign to support and display the sign. The legs and feet have retracted positions near the mast. A rearwardly extending formation of the horizontal support member can be coupled to a vehicle hitch so the sign base also can be supported on a vehicle for transport while displaying a sign.
