Abstract
Abstract A convertible top for pick-up trucks is disclosed having front and rear shells with a collapsible canopy therebetween and the rear shell being movable on side rails from a retracted to an extended position of the top. In the closed position, the rear shell is telescoped into the front shell and the canopy, including plural bows and a flexible sheet, are stowed inside the capsule formed by the shells. The rear shell is supported on the rails by a pair of carriages and the bows are individually carried at opposite ends by a pair of bow carriers. A latch is mounted on a swivel on each carriage and coacts with a front latch keeper on the rail in the retracted position and a different latch keeper on the rail in the extended position. A storage cabinet is disposed beneath the front shell and supported on the truck bed and is accessible through the cab window and a front window in the front shell and also through a rear window in the rear shell. A brake lamp is mounted on the rear shell and adapted to be plugged in to the brake lamp circuit of the vehicle for use when the convertible top is either retracted or extended.
