FIELD OF THE INVENTION
The invention relates to pick up truck accessories than can be added to pickups to make them more useful. More specifically the invention relates to an improved design for storing the rear door of a pickup truck topper. The improved design is substantially a retractable system for storing the rear door of a pickup truck topper. The side windows can also utilize the new concept for storing the windows in an retracted open position.
DESCRIPTION OF PRIOR ART
Pickup trucks are very popular vehicles for consumers. This type of vehicle is often utilized for personal, recreational, and businesses purposes. Pickups are available from numerous manufacturers and are available in a wide variety of sizes and styles and models. There are small compact pickups, mid-size pickups, and full size pickups including half ton and three quarter ton pickups. Some of these vehicles have a regular size cab and cargo beds. Other versions have “king cabs” with front seats and rear seats. Some pickups have two doors and some have four doors. Some pickups have short cargo beds and some have long extended cargo beds.
An accessory that is often added to pickups is a “truck topper.” These devices are sometimes called a “truck cap” or a “truck camper” or a “truck bed cap” or a “pickup truck cap” etc. A truck topper generally provides an enclosed compartment above the pickup cargo bed. Most toppers can be locked to prevent any enclosed tools and personal items from being stolen. Animals and humans can occupy the enclosed space of a pickup topper. Also the topper protects the cargo bed and contents from the rain and snow and bad weather, etc.
Typically toppers have a roof, two side walls, a front wall adjacent the pickup cab and a rear opening with some type of rear door which opens and closes above the pickup tail gate. Typically the top of the rear door is hinged near the roof of the topper.
Toppers are available in a variety of styles and shapes and designs. Consumers can purchase different designs that suit their needs. Typically the front wall of a pickup topper, which is adjacent the pickup cab, matches the contour of the truck cab. The top of the topper has a shorter length and the sides flair outward, generally matching the contour of the truck cab. The bottom edge of the front wall generally matches the dimension of front wall of the pickup bed. The topers can have a streamlined design with the front portion and the rear portion having similar height dimensions. If more cargo space is desired the roof top can arc upward as the roof makes a transition from the front of the topper to the rear of the topper. If the rear of the topper has a large opening, a large door can be incorporated. A large topper door allows bulky items to be loaded and unloaded from the back of the pickup.
Some toppers utilize one piece windows that do not include a metal frame. The hinge mechanism and the struts are fastened through holes in the one piece window.
Toppers can be made of a variety of materials such as aluminum, fiberglass, carbon fiber, wood, steel, plastic, etc.
The side panels of toppers can have a variety of designs. The side panels can have permanent windows that cannot be opened, plastic “bubble” windows, windows that swing outward, windows that swing inward, windows that slide horizontally, etc. Topper side panels can also have doors that swing outward, doors that swing inward, doors that slide horizontally, etc Topper side panels can also be made so that there are no windows or doors.
Toppers can have sun roofs to allow light into the interior of the topper. Some toppers have interior lights and brake lights incorporated thereon.
Some pickup toppers have racks incorporated thereon which can hold long items such as ladders and/or lumber, etc.
The truck topper rear opening typically has a hinged door that moves between an open position and a closed position. Often the rear door has two hinges on the top and it is hinged to the topper roof. Rear doors generally have a metal frame and the door also has a clear window. Often the back window as a trapezoid shape; the top and the bottom of the door are parallel to one another and the top has a shorter length than the bottom of the door. The two side sections of the door connect the shorter top to the longer bottom portion of the door.
Many toppers also have a pair of struts that are connected between the sides of the back door and the sides of the back of the truck. The struts are usually biased with a spring type of mechanism that lifts the back door to an open position and keeps the door in the open position.
Most toppers have some type of locking mechanism. There are one handle designs with linkage that extend to the sides of the back wall for locking. Some toppers have two locking mechanisms; one on left side and one on the right side of the topper door.
Although truck toppers with hinged rear doors are popular there are numerous problems associated with them including the following:
When the topper rear door is left in the open position it can be a serious hazard for someone walking in the area. They could injure their head by walking into an opened door if they are unaware that the door is open.
Also, when the topper rear door is in its open horizontal position, there is often restricted head clearance near the tailgate area of the pickup. Unloading items from the pickup bed and loading items into the pickup bed can be cumbersome if someone can not stand upright during the unloading and/or unloading.
When long items are hauled in the pickup bed, the topper door must be left open and that can be problematic. The door often can flap in the wind, and vibrate and jerk and wear out the hinges and various different components. The struts can be damaged. Also, the window can break. If a rear topper door that has been left in the open position should fall from its open position, the cargo extending out from the pickup bed may be damaged.
Some toppers have racks on the top for hauling long items such as ladders and or long boards, etc. When long items are hauled in the rack on top of a topper, most topper doors cannot be placed in a fully open position because the ladder and/or boards extend beyond the end of the topper. This can be problematic. As it would be hard to place items into the topper and/or take items out of the topper when the rack has items thereon. Also, the window can break if the window would ever hit any items extending rearward beyond the topper rack.
The topper rear door struts tend to wear out and may not hold the door properly in the open position which can be hazardous. Worn struts can be expensive to replace.
When hauling a trailer with a pickup that has a topper can lead to problems. If the topper door is left open it may be damaged by the trailer during turns. Also, if the topper door is open, working in the area of the trailer hitch can be hazardous and cumbersome.
If a topper rear door is left in the open position, it can be damaged during backing of the pickup near any building or a garage or a loading dock.
Some topper designs have a hinged rear door that extends beyond the horizontal position when the door is in the open position. With these designs, the hinged door, when in the open position, can be higher than the height of the back of the topper. When these doors are in the fully open position, shorter people may have a hard time reaching the open door to pull it into the closed position.
