Multipurpose sign bases for supporting temporary roadway safety signs and the like
First Claim
1. A multipurpose sign base suitable for supporting a roadway safety sign, comprising an upstanding mast supportable atop a ground surface by a substantially horizontally extending, elongate, ground surface engageable 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 a lower portion movably connected to a different ground surface engageable foot, with an upper region of the mast being adapted for connection to a roadway safety sign to support and display the roadway safety sign.

Abstract
A multipurpose sign base suitable for supporting temporary roadway safety signs and the like includes an upstanding mast supportable atop a ground or 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 an underlying ground or support surface at locations arrayed about the mast. An upper region of the mast is connectable to a roadway safety sign or the like, 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 preferably can be coupled to a vehicle hitch so the sign base also can be supported on a vehicle for transport while displaying a sign carried by the mast of the sign base.

- 1. A multipurpose sign base suitable for supporting a roadway safety sign, comprising an upstanding mast supportable atop a ground surface by a substantially horizontally extending, elongate, ground surface engageable 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 a lower portion movably connected to a different ground surface engageable foot, with an upper region of the mast being adapted for connection to a roadway safety sign to support and display the roadway safety sign.
- 13. A multipurpose sign base for supporting a roadway safety sign comprising an upstanding mast having at least an upper mast component and a lower mast component that are telescopically extensible and retractable, and that have a gas spring interposed therebetween to aid in raising the upper mast member relative to the lower mast member by releasing energy stored by the gas spring during lowering of the upper mast member relatively to the lower mast member.
- 21. A multipurpose sign base for supporting a roadway safety sign comprising an upstanding support mast connected to a retractable set of legs that can be moved from extended ground surface engageable positions supporting the sign base atop an underlying ground surface to retracted positions extending near a lower region of the support mast, and a formation connected to the mast and attachable to a hitch of an over-the-road vehicle for supporting the mast from the vehicle hitch instead of from the legs engaging an underlying ground surface.
- 26. A multipurpose sign base comprising an extensible and retractable upright mast having an upper component and a lower component that are relatively movable, and having three legs pivotally connected to the lower component for supporting the mast atop a support surface, with the length of at least a selected one of the legs being adjustable to enable the legs to support the mast in a substantially vertical orientation, and with the selected one of the legs having an associated foot formation for engaging a portion of the underlying support surface, and carrying a spike member that can extend telescopically beneath the associated foot formation to penetrate the underlying support surface portion.
- 32. A multipurpose sign base having an upstanding mast with an upper region attachable to a roadway safety sign, having a lower region to which a substantially horizontally extending, elongate support member is connected that carries a foot formation for engaging a support surface in a first area of contact, and having three elongate, telescopically extensible legs with upper end portions pivotally connected to a central region of the upstanding mast for pivoting between retracted positions near the mast and extended positions wherein foot formations carried by lower portions of each of the three legs engage the support surface at second, third and fourth areas of contact spaced from each other and from the first area of contact for supporting the upstanding mast in a substantially vertical orientation atop the support surface.
- 44. A multipurpose sign base having an elongate, telescopically extensible, upstanding mast that, near the lower end thereof, has a first and second open-ended components with adjacent open end regions connected and held in alignment with each other by a block of structurally weakened metal that extends into the aligned, adjacent, open end regions and is connected thereto to provide a breakaway connection adapted to sever when the sign base is impacted by a massive moving object such as a motor vehicle.
