Sign holding extrusion-attachment arrangement
View Patent ↗A sign hanging tool assembly for the attachment of a sign holding extrusion to a ceiling rail in a ceiling. The assembly comprises an extrusion tool mounted on an end of an elongated pole. The extrusion tool comprises a T-frame and a bias arm shaft. The T frame has a rear flange for engagement with a slot on the sign holding extrusion. The bias arm shaft is spaced apart and parallel to the rear flange for locating and engaging the sign holding extrusion therebetween.
1. A sign hanging tool assembly for the attachment of a sign holding extrusion to a ceiling rail in a ceiling, comprising:
an extrusion tool mountable on an end of an elongated pole, said extrusion tool comprising a T-frame and a bias arm shaft, said T frame having a rear flange for engagement with a slot on said sign holding extrusion, said bias arm shaft being spaced apart and parallel to said rear flange for locating and engaging said sign holding extrusion therebetween, the rear flange having a tapered elongated boss thereon to permit pressed orthogonal wedging entry into said sign holding extrusion, the elongated boss having a tapered surface at each end thereof, the tapered surface at each end of said elongated boss comprising a generally triangularly shaped first face and a generally triangularly shaped second face.
2. The sign hanging tool assembly as recited in claim 1 , wherein said bias arm shaft has a flat face thereon which is parallel to said rear flange.
3. The sign hanging tool assembly as recited in claim 2 , wherein said flat face on said bias arm shaft and said rear flange are spaced apart so as to snugly support a sign holding extrusion there-between.
4. The sign hanging tool assembly as recited in claim 1 , wherein said elongated boss has an angled face sloping towards said bias arm shaft.
5. The sign hanging tool assembly as recited in claim 1 , wherein said rear flange is attached to said bias arm shaft by an elongated bridge member connectively spaced therebetween.
