Abstract
Abstract A sign support structure, such as for supporting a distress flag or any other information-carrying flag. The structure comprises an elongated main shaft which is secured at a lower end to a support base having a magnet therein. A flat support surface is provided under the support base whereby the base can be attached to any metal surface such as the roof top or door of a car. A coupling element is removably secured to an upper end of the main shaft and has a transverse support shaft secured thereto. The coupling element also has an axial bore opening in a lower end thereof to receive a free end portion of the upper end of the main shaft. Furthermore, the coupling element has a second bore disposed transverse to the axial bore and above a base of the axial bore and above the axial bore and below the transverse support shaft for receiving the free end portion of the main shaft when the support structure is in a storage position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
199 words
A sign support structure comprising an elongated main shaft secured at a lower end to a support base, said support base having a magnet secured therein, a flat support surface under said support base, a coupling element removably secured to an upper end of said main shaft, a transverse support shaft secured to said coupling element, said coupling element having an axial bore opening in a lower end thereof to receive a free end portion of said upper end of said main shaft, said coupling element further having a second bore disposed transverse to a longitudinal axis of said axial bore and located above said axial bore and below said transverse support shaft for receiving said free end portion of said main shaft when said support structure is in a storage position, a removable flag supported by said main and transverse shafts, said second bore being dimensioned to receive said free end portion ofsaid main shaft in friction fit therein, when said support structure is in said storage position, said main shaft and transverse support shaft being disposed substantially parallel and in close relationship to one another with said flag retained by said transverse shaft and said main shaft.
Claim 2
Dependent Claim
199 words
A sign support structure comprising an elongated main shaft secured at a lower end to a support base, said support base having a magnet secured therein, a flat support surface under said support base, a coupling element removably secured to an upper end of said main shaft, a transverse support shaft secured to said coupling element, said coupling element having an axial bore opening in a lower end thereof to receive a free end portion of said upper end of said main shaft, said coupling element further having a second bore disposed transverse to a longitudinal axis of said axial bore and located above said axial bore and below said transverse support shaft for receiving said free end portion of said main shaft when said support structure is in a storage position, a removable flag supported by said main and transverse shafts, said second bore being dimensioned to receive said free end portion ofsaid main shaft in friction fit therein, when said support structure is in said storage position, said main shaft and transverse support shaft being disposed substantially parallel and in close relationship to one another with said flag retained by said transverse shaft and said main shaft.
Claim 3
Dependent Claim
39 words
