Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
174 words
A crash bar assembly for a vehicle chassis having auxiliary equipment mounting means projecting rearwardly therefrom, said crash bar assembly comprising: a solid impact absorbing bar having foldable side extension arms connected to said solid impact absorbing bar, said side extension arms being lockable in an extended position; impact bar mounting means for mounting the solid impact absorbing bar adjacent the rear of the vehicle chassis, the mounting means allowing movement of the solid impact absorbing bar from a storage position to an operative position beyond the vehicle chassis and spaced apart therefrom; locking means for securing the solid impact absorbing bar in its extended position; and a mounting kit for supporting the wheels of auxiliary equipment, the side extension arms being folded inwardly, away from the solid impact absorbing bar when the wheels are located on the mounting kit and, after movement of the solid impact absorbing bar to the operative position, the side extension arms are folded outwardly and locked in said extended position to provide a fully rigid crash bar assembly.
Claim 2
Dependent Claim
174 words
A crash bar assembly for a vehicle chassis having auxiliary equipment mounting means projecting rearwardly therefrom, said crash bar assembly comprising: a solid impact absorbing bar having foldable side extension arms connected to said solid impact absorbing bar, said side extension arms being lockable in an extended position; impact bar mounting means for mounting the solid impact absorbing bar adjacent the rear of the vehicle chassis, the mounting means allowing movement of the solid impact absorbing bar from a storage position to an operative position beyond the vehicle chassis and spaced apart therefrom; locking means for securing the solid impact absorbing bar in its extended position; and a mounting kit for supporting the wheels of auxiliary equipment, the side extension arms being folded inwardly, away from the solid impact absorbing bar when the wheels are located on the mounting kit and, after movement of the solid impact absorbing bar to the operative position, the side extension arms are folded outwardly and locked in said extended position to provide a fully rigid crash bar assembly.
Claim 3
Dependent Claim
23 words
A crash bar assembly as claimed in claim 1, in which the impact bar mounting means is telescopically mounted on the vehicle chassis.
Claim 4
Dependent Claim
92 words
A crash bar assembly as claimed in claim 2, in which the impact bar mounting means comprises: a pair of rearwardly extending support bars connected in spaced apart relationship to the solid impact absorbing bar; a pair of sockets for reception of the support bars; means for rigidly connecting the sockets to a vehicle chassis; and locking means for securing the support bars in a number of different relative locations within the sockets comprising a locking pin and associated alignment means formed by axial through holes in the support bars and sockets.
