ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to camper devices and more specifically it relates to a collapsible portable camper system for folding into a compact position during nonuse and for expanding into a spacious camper while positioned upon a pickup.
2. Description of the Prior Art
Camper devices have been in use for years. Typically, a conventional camper has a floor, front and rear walls, side walls and a roof forming a rigid and rectangular structure. For conventional campers designed to fit upon a conventional pickup, the main problem is that the overall width is limited because of road restrictions and safety concerns.
Therefore, the interior portion of a conventional camper designed for a conventional pickup is typically not comfortable for extended stays. In addition, many conventional campers have a width that is much wider that the pickup making it difficult to navigate around objects. Also, the overhang is dangerous to individuals walking around the conventional camper when not in use because they may engage the overhang with their bodies.
While these devices may be suitable for the particular purpose to which they address, they are not as suitable for folding into a compact position during nonuse and for expanding into a spacious camper while positioned upon a pickup. Conventional campers are difficult to navigate a pickup with because they block view with the side mirrors. Also, conventional campers are prone to engaging objects near the vehicle making them a hazard.
In these respects, the collapsible portable camper system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of folding into a compact position during nonuse and for expanding into a spacious camper while positioned upon a pickup.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of camper devices now present in the prior art, the present invention provides a new collapsible portable camper system construction wherein the same can be utilized for folding into a compact position during nonuse and for expanding into a spacious camper while positioned upon a pickup.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new collapsible portable camper system that has many of the advantages of the camper devices mentioned heretofore and many novel features that result in a new collapsible portable camper system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art camper devices, either alone or in any combination thereof.
To attain this, the present invention generally comprises a first wall, a second wall attached to a floor, a pair of side walls, a first platform and a second platform pivotally attached to the side walls, a roof, a tarp attached to the roof, and an elevating structure that extends and retracts the roof. A plurality of support shafts are attached to the roof that are slidably attached to the first wall and the second wall, and that are mechanically coupled to the elevating structure. A plurality of rollers are preferably rotatably attached to the lower surface of the floor for allowing easy removal and insertion upon a conventional pickup. At least one netting is positioned within the tarp serving as a window for the invention. A crank handle is removably attachable to a crank sprocket that is positioned about a crank shaft that extends between the first wall and the second wall. The user simply manipulates the crank handle to elevate the roof thereby allowing the first platform and the second platform to be extended and which are thereafter supported by a plurality of support cables. A pair of wall frames are removably inserted into receiving tubes upon the platforms and the tarp is thereafter attached to hooks on the lower surface of the platforms forming a spacious interior compartment.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and that will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of the description and should not be regarded as limiting.
A primary object of the present invention is to provide a collapsible portable camper system that will overcome the shortcomings of the prior art devices.
Another object is to provide a collapsible portable camper system that folds into a compact storage position.
An additional object is to provide a collapsible portable camper system that expands forming a spacious interior for individuals to utilize.
A further object is to provide a collapsible portable camper system that is removably positionable upon a conventional pickup.
Another object is to provide a collapsible portable camper system that does not interfere with the normal operation of the pickup while attached to the pickup.
An additional object is to provide a collapsible portable camper system that is easily extended and retracted by a single user.
Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages are within the scope of the present invention.
To the accomplishment of the above and related objects, this invention may be embodied in the form illustrated in the accompanying drawings, attention being called to the fact, however, that the drawings are illustrative only, and that changes may be made in the specific construction illustrated and described within the scope of the appended claims.
