Vehicle parking signal device

Claim 1

In combination with a vehicle and a vehicle enclosure, such as a garage, having a ceiling structure, an alarm for signalling to the vehicle operator when the vehicle has advanced to a desired parking position in the garage comprising, an elongated support member mounted on the ceiling structure at a level above the roof of the vehicle and extending in a direction parallel to the longitudinal axis of the vehicle in said park position, a bracket mounted on said support for movement lengthwise thereof, means for locking the bracket in a fixed predetermined position lengthwise of the support, a generally vertically extending switch arm having an upper member and a lower member, said upper member having its upper end pivotally connected to said bracket for swinging movement about a horizontal axis extending perpendicular to the longitudinal axis of said support member, said lower member having its lower end terminating at a level above the roof of the vehicle, said lower arm member being movable vertically on the upper arm member so as to vary the extent to which the lower end of the arm projects downwardly from said pivot axis, means for locking said arms together in a predetermined fixedly extended position, a generally horizontally extending cross arm mounted on the lower end of the lower switch arm member, said cross arm being spaced above the roof of the vehicle when in said park position, said cross arm projecting transversely of the longitudinal axis of the vehicle from opposite sides of the switch arm, a vertically extending antenna mounted on the vehicle in a predetermined position and projecting upwardly above the roof of the vehicle, the upper end of said antenna lying in a plane above said cross arm and offset laterally from said switch arm when the vehicle is in said park position, said support member being mounted on said ceiling structure and said bracket being mounted on said support member in such positions in relation to said antenna so that one end portion of the cross arm lies in the path of travel of and is engaged by said antenna to tilt said switch arm forwardly when the vehicle is advanced to said part position and an alarm responsive to said forward tilting movement of said switch arm for signalling to the vehicle operator that the vehicle has advanced to said desired park position.
