  • Patent number: 6209944
    Abstract: A stowable top or cover mounted on an open bed of a truck, such as a pickup truck, using lift frames and actuators in a manner to be raised above the bed. The cover and lift frames include attachment channels for connecting a flexible tent-like enclosure thereto such that the enclosure can be attached thereto after the cover is raised. The flexible enclosure can comprise a camper enclosure that encloses the truck bed and also optionally can extend beyond the truck bed to form additional sitting and sleeping rooms supported on separate portable tent-type posts and platforms. A flexible awning enclosure can be attached to the raised cover and lift frames to form an awning that extends beyond the truck bed supported on separate tent-type posts to provide a covered area for on-site work/commercial/recreational activities. An office enclosure can be attached to the raised cover and lift frames to form an office or meeting room where job-site work/meetings and the like can be conducted protected from the weather.

  • Patent number: 5427429
    Abstract: An improved bow for a convertible top is described which is molded from a polymeric resin such as nylon and reinforced with glass fibers. The bow has a general I beam cross section and can be reinforced for additional strength. The ends of the bow can be configured to retain stay pads or tack strips. The bow can be molded in a set of tools that have interchangeable ends and retain the same mold for the central section of the bow. The interchangeable tools for producing the ends of the bow allow for greater manufacturing flexibility in that the central tool is retained for use in producing multiple styles of bows while expenses only have to be incurred for additional tooling for the ends of the bows.
