Aerodynamic transformable truck cap assembly

Abstract

A transformable, aerodynamic cover assembly for pickup trucks which is user switchable between a closed aerodynamic configuration and a fully deployed truck cap configuration. The aerodynamic configuration reduces vehicle wind resistance and drag, thus increasing fuel efficiency. The cover assembly, constructed of rigid materials, comprises a fiberglass shell mounted within the truck bed supporting a rigid, fiberglass cover. Flexible fabric windows suspended from the cover are supported between sidewall hangers and pivoted sleeve tubes. A flexible rear hatch is supported by a transverse hanger. Internal stanchions pivoted to the cover underside foldably switch between deployed, cover-elevating positions an stowage positions. The cover sidewalls and hatch provide a space for human habitation and increased cargo hauling capacity. The cover is detachable from the body of the assembly for hauling oversized cargo.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This utility patent application is based upon, and claims the priority filing date of my previously-filed, U.S. Provisional patent application entitled “Aerodynamic Transformable Truck Cap Assembly,” filed Oct. 1, 2007, Ser. No. 60 / 997,085.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates generally to truck caps and cover assemblies for pickup trucks. More particularly, this invention relates to an aerodynamic cover assembly for pickup truck beds that is user-transformable between selected configurations. Known prior art relevant to this invention can be found in U.S. Patent Class 296, subclasses 100 and 165.[0004]2. Description of Prior Art[0005]For several years, cover assemblies of various forms have been mounted on the beds of pickup trucks. The modern truck cap is a popular pickup truck accessory, providing a variety of functional and aesthetic advantages. Prior art cover assemblies provide a cover...

AI Technical Summary

Benefits of technology

[0013]The invention, an improved aerodynamic truck cap assembly, is user transformable between a streamlined, aerodynamic position and an elevated position increasing cargo space. The aerodynamic configuration reduces vehicle wind resistance and drag, and increases fuel efficiency.

[0016]The user can deploy the sidewalls and hatch from the underneath of the roof to fully enclose the truck bed. Thus my new aerodynamic truck cap is readily adaptable for hauling, or it can provide a space for human habitation. In the elevated and enclosed configuration, the user can operate the host vehicle at sustained freeway speeds.

[0017]Accordingly a fundamental object of the invention is to provide an improved aerodynamic truck cap to lower wind resistance and enhance the fuel efficiency of the host pickup truck.

[0018]Another basic object is to provide a truck cap assembly with a removable cover that quickly and conveniently mounts to or dismounts from the apparatus shell.

[0020]It is also an object to allow operation of the host pickup truck while in motion with the aerodynamic truck cap disposed in either an elevated or enclosed configuration. Further, an important object is to provide a truck cap of the character described with durable structure to endure aerodynamic forces experienced at sustained high rates of speed.

[0021]Another object is to provide a truck bed cover assembly of the character described that can be quickly transformed between configurations.

Problems solved by technology

Such accessories often increase aerodynamic drag, and reduced fuel economy is unfortunately typical.

The main drawback of the aerodynamic truck cap is that, with its slope, there is a substantial loss of interior volume over that provided by a truck cap with a roof flush with the cab of the pickup.

This diminishes the space for human habitation and cargo stowage in the aerodynamic truck cap over that space provided by a standard truck cap.

The small entrance through the tailgate opening does not facilitate easy access for human habitation.

There is no ventilation provided for human or domestic animal occupancy.

Valuable cargo is also more vulnerable to theft when the host vehicle is left unattended.

However, the overall configuration did not exhibit the desired reduction in wind drag necessary in today's world to maximize fuel economy.

In conclusion, I am aware of no easily removable, aerodynamic truck cap designed to reduce wind drag in one mode, to user-deploy into a convenient camping or storage mode, and which protectively enshrouds truck bed contents in either mode.
