FIELD 
     The invention relates generally to a vehicle storage unit and more particularly to a portable or moveable carport. Embodiments as described herein are able to be quickly and easily set up and taken down while still shielding a vehicle from rain, snow and sun—the primary destroyers of automotive paint, body and interiors. 
     BACKGROUND 
     An automobile, boat, or other vehicle is a sizable investment to most consumers. Collector cars are a popular investment, but many owners do not have expensive garages, carports or other storage means readily available to protect their vehicles from the elements. Fabric and plastic car covers are available, but car covers that are not breathable or let moisture through, can cause severe damage to a vehicle&#39;s finish if water is trapped under the cover. Good breathable car covers are expensive and can still chafe the car&#39;s finish, and also allow water or dust to penetrate. Additionally, car covers are unwieldy, tend to wear out quickly and can be damaged by UV radiation or adverse weather. As a solution, heavy carports are available, but they suffer from the need to be attached to the ground via lag bolts, ropes, or other mechanical means to make them at least semi-permanent. Portable shelters are usually complicated in design, are susceptible to collapse due to their lightweight structure, and most importantly, difficult to manufacture. As a result, these protective portable devices have not received any commercial success. 
     SUMMARY 
     Described herein is a portable or moveable carport that is able to be quickly and easily set up and taken down, is able to structurally withstand high winds and foul weather, and shield a vehicle from rain, snow and sun—the primary destroyers of automotive paint, body and interiors. The structure has no more than four vertical supports supporting an A-frame roof structure. The vertical legs are anchored under the vehicle&#39;s four tires with adjustable two piece anchor plates which can be driven onto once the structure is assembled. A fabric or plastic roof provides protection from the elements, and sides, front, and back may be additionally added to the carport. 
     A first aspect comprises a carport comprising no more than four anchor plates, wherein each plate comprises a plate that sits on the ground and may be placed under the wheels of a vehicle, no more than four vertical elements that are connected to the four foot pads inserted up through a whole in each anchor plates, a roof structure comprising two transverse elements that are approximately parallel to each other and the ground and each connect two vertical elements to each other, a single peak element that is approximately parallel to the transverse elements and the ground, four connecting elements, wherein two of each connecting element connect the peak element to a transverse element. Both the two transverse elements and the single peak rafter element always extend beyond the vertical elements area making a larger roof area than the vertical elements area. The transverse elements and the peak element are able to be dissembled into sub-sections of length no greater than five feet. In some embodiments, the anchor plates are able to be rotated around the axis formed by the vertical elements, for example the anchor plates are able to be rotated over an angle of about 160 degrees. 
     The roof pitch in some cases may be from about 1/12 to about 18/12. The roof element may comprise any material, but in some cases it is fabric, plastic or combination thereof. In embodiments, roof element is attached to the transverse elements by wire, flexible or fixed ties, rope, zip ties, buttons, zippers, or hook and eye elements. In some designs, the carport further comprises side elements that comprise a fabric, plastic, or combination thereof, and wherein the side elements attach to the vertical elements and the transverses elements. 
     The carport may further comprise a first sleeve element comprising a sleeve structure with openings for the vertical element, the transverse element, and the connecting element and/or a second sleeve element comprising a sleeve structure with openings for the connecting element and the peak element. 
     In a particular embodiment of the carport, the anchor plates comprise aluminum, the vertical elements, the transverse elements, the peak element, and the connecting elements, and the first and second sleeve elements all comprise aluminum, steel, iron, plastic, fiberglass or carbon fiber. 
     Other aspects and modes of the invention will be apparent from the following description and the appended claims.

     DETAILED DESCRIPTION 
     Aspects will now be described in detail with reference to embodiments, as illustrated in the accompanying drawings. In describing the embodiments, numerous specific details are set forth in order to provide a thorough understanding. However, it will be apparent to one skilled in the art that embodiments may be practiced without some or all of these specific details. In other instances, well-known features and/or process steps have not been described in detail so as not to unnecessarily obscure the description. In addition, like or identical reference numerals are used to identify common or similar elements. 
     The following describes a portable or moveable carport that provides the following advantages: it is able to be quickly and easily set up and taken down, it is able to structurally withstand high winds and foul weather, and critically, it is able to shield a vehicle from the primary destroyers of automotive paint, body and interiors—rain, snow and sun. Further, the carport is secured to the ground without the need for rope, wire or other types tie downs or other external devices that are secured in the ground and take up additional space outside of the carport. 
     A first embodiment of the carport frame  10  is shown in  FIG. 1 . The carport frame  10  is secured and stabilized by four anchor elements,  102 , which comprise a tire plate, or “paw,”  100 , that is aligned under the wheels of a vehicle placed in the carport and a foot pad,  101  ( FIG. 2  and  FIG. 3 ). The foot pad,  101 , may be connected to the paw, for example via welds, screws, bolts, etc. or may separate from the paw. For example, as shown in  FIG. 4 , the foot pad,  101 , may comprise a tubular element,  401 , connected to a small base plate,  402 . In this embodiment, the paw  100  has a hole slightly larger than the tubular element,  401 , which allows it to be laid on top of the foot pad and “lock” the footpad down with the weight of the vehicle. In some embodiments, the footpad and paw are “keyed” such that rotational movement of the paw can be limited to a certain angular range, e.g., 90° or 135° or, alternatively, so that rotational movement of the paw can be controlled by rotation of the foot pad around the axis formed by the vertical element  110 . 
     Again looking at  FIG. 1 , linear elements  110 ,  130  ( 130  comprising  131  and  132 ),  140 , and  160 , can be made from any practical material, e.g. polymer, metal, wood, etc. However, due to cost, strength, and ease of use, metal tubing is typically used. In some embodiments, the metal tubing is circular tubing made of iron, steel, or aluminum. The tubing diameter can be chosen for the application, but iron pipe tubing of from 1-2″ is typically sufficiently strong enough to provide the desired flexural strength and structural integrity needed in most carport applications, while still being sufficiently light enough to provide ease of transport and setup. Because one aspect of the design is to make the carport easily transportable, it is desirable in some embodiments to make the linear elements  110 ,  130 ,  131 ,  132 ,  140 , and  160  sectionable into smaller sub-sections, or alternatively, the element is designed to telescope, or collapse to a length that is easily transportable in a standard automobile. In some embodiments, the linear elements  110 ,  130 ,  131 ,  132 ,  140 , and  160 , have a length no longer than about 6′, 5′, 4′, or 3′. 
     Similarly, connector-type elements  120  and  150  can be made from any practical material, e.g. polymer, metal, wood, etc. However, again due to cost, strength, and ease of use, metal is most convenient. In some embodiments, the connector elements  120  and  150  are made of the same material as the linear elements  110 ,  130 ,  140 , and  160 . In cases where the linear elements  110 ,  130 ,  140 , and  160  slide into or over the connector elements  120  and  150 , the size of the connector elements  120  and  150  is chosen to provide a snug fit without binding—such as 0.1″ larger or smaller. Either the linear elements  110 ,  130 ,  140 , and  160  or the connector elements  120  and  150  may further incorporate mechanisms to lock the elements together. For example, the linear elements  110 ,  130 ,  140 , and  160  may slide into one or more connector elements  120  and  150  and optionally, be locked in place by a set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” apparatus, or the like. Alternatively, the linear elements  110 ,  130 ,  140 , and  160  may slide over one or more connector elements  120  and  150  and be optionally secured via similar devices. In still another embodiment, connector elements  120  and  150  and foot pad  101  may be integrated into or part of one or more of the linear elements  110 ,  130 ,  131 ,  132 ,  140 , and  160  they connect or connect to. 
     Looking again at  FIG. 1 , each foot pad,  101 , is attached to a vertical element,  110 . Attachment between the vertical element,  110 , and the footpad  101 , may be through any number of possibilities known to one of skill in the art. For example, the vertical element may slide into the footpad and optionally, be locked in place by a set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” apparatus, or the like. Alternatively, the vertical element may slide over the footpad and be optionally secured via similar devices. Still another possibility is that vertical element,  110 , and footpad,  101 , screw together. 
     Continuing to look at  FIG. 1 , vertical element,  110 , attaches to transverse element  130  via connecting element  120 . Connecting element  120  comprises an element that is capable of linking vertical element  110  to transverse element  130  (for sake of clarity, transverse element  130  as described in  FIG. 1  does not include elements  120 ), and optionally to rafter element  140 . In some embodiments, for example as shown in  FIG. 5 , connecting element  120  comprises a sleeve-type, two-, three-, or four-tube connector, a two-, three-, or four-tube threaded connector, a clamp-type apparatus, a strap, a latching apparatus, or the like. Generally, vertical element  110  slides into or over connecting element  120  and is secured via methods known in the art, such as by a set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” apparatus, or the like. 
     Transverse element  130  can comprise one continuous element that is optionally sectionable into smaller sub-sections, or alternatively, the element is designed to telescope, or collapse to a length that is easily transportable. In some embodiments, the transverse element  130  does not continue through connecting element  120 , but rather threads or locks into it, or butts up against an internal component of it. For example, transverse element  130  may comprise one or more outer transverse element sections  131  that attach to the connecting element  120  and one or more inner transverse element sections  132  that join two connecting elements  120 . In some embodiments, outer and inner transverse elements,  132  and  131 , respectively, slide into or over connecting element  120  or screw into connecting element  120 , and can be secured to connector  120  via methods known in the art, such as by a set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” apparatus, or the like. 
     Alternatively, in some embodiments, the transverse element  130  is a continuous element that passes through connector element  120  and may optionally be made of smaller subsections. In cases where transverse element  130  comprises smaller subsections, these subsections may slide together, screw together, or lock together through methods known to those skilled in the art, such as set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” locking apparatus. When transverse element  130  is continuous, connecting element  120  is designed to clamp or lock around it. In some embodiments, the clamping or locking mechanism can be, for example, a set screw, bolt, screw, pin, spring-loaded “button-type” apparatus, a clamp-type apparatus, a strap, a latching apparatus, or the like. In embodiments where the transverse element  130  is continuous, the connecting element  120  in an unlocked or state may be traversable along the transverse element,  130 . This is advantageous as it allows for movement of the vertical elements  110  to compensate for changes in vehicle length. 
     As noted above, in some embodiments where the transverse element  130  is a continuous element, connecting element  120  is secured to the transverse element in a manner that allows it location to be varied. An example embodiment is shown in  FIG. 6  where connecting element  120  can be moved as shown by arrow  126 . Further, as shown in  FIG. 6 , when connecting element  120  only secures the vertical element  110  to the transverse element  130  (i.e., does not also secure the rafter element  140 ), the connecting element  120  (vertical-transverse connecting element) and the connecting element  121  (transverse-rafter connecting element) can move independently of each other (shown as arrows  126  and  125 , respectively). Both connecting elements  120  and  121  may be secured to the transverse element  130  via a locking mechanism, a clamp mechanism, a strap mechanism, a set screw, or the like ( FIG. 6 ,  610 ). 
     Rafter element,  140 , as shown in  FIGS. 1 and 6 , may be attached to transverse element  130  via connector element  120  or via connector element  121 . Generally, rafter element  140  slides into or over connector element  120  or connector element  121  and is secured via methods known in the art, such as by a set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” apparatus, or the like. Alternatively, rafter element  140  may screw or thread into connecting elements  120  or  121 . 
     Again, looking at  FIG. 1 , rafter element  140  connects to peak element  160  via peak connector element  150 . Peak connecting element  150  comprises an element that is capable of linking rafter element  140  to peak element  160  ( FIG. 1 ). In some embodiments, for example as shown in  FIG. 7 , peak connecting element  150  comprises a sleeve-type, two-, three-, or four-tube connector, a two-, three-, or four-tube threaded connector, a clamp-type apparatus, a strap, a latching apparatus, or the like. Generally, rafter element  140  slides into or over peak connecting element  150  and is secured via methods known in the art, such as by a set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” apparatus, or the like. 
     Peak element  160  is similar to transverse element  130  and can comprise one continuous element, that is optionally sectionable into smaller sub-sections, or alternatively, the element is designed to telescope, or collapse to a length that is easily transportable. In some embodiments, peak element  160  does not continue through peak connecting element  150 , but rather threads or locks into it, or butts up against an internal component of it. For example, as described above for transverse element  130 , peak element  160  may comprise inner and outer sections that connect to peak connecting element  150 . Outer and inner peak elements can be secured to peak connector  150  via methods known in the art, such as by a set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” apparatus, or the like. 
     Alternatively, in some embodiments, the peak element  160  is a continuous element that passes through peak connector element  150  and may optionally be made of smaller, subsections. In cases where peak element  160  comprises smaller subsections, these subsections may slide together, screw together, or lock together through methods known to those skilled in the art, such as set screw, bolt, screw, pin, clamp, or spring-loaded “button-type” locking apparatus. When peak element  160  is continuous, peak connecting element  150  is designed to clamp or lock around it. In some embodiments, the clamping or locking mechanism can be, for example, a set screw, bolt, screw, pin, spring-loaded “button-type” apparatus, a clamp-type apparatus, a strap, a latching apparatus, or the like. In embodiments where the peak element  160  is continuous, the peak connecting element  150  in an unlocked or state may be traversable along the peak element,  160 . 
     As noted above, in some embodiments where the peak element  160  is a continuous element, peak connecting element  150  is secured to the peak element  160  in a manner that allows it location to be varied. Similar to that shown for peak transverse element  150  in  FIG. 1 , peak connecting element  150  can be moved relative to peak element  160 . Additionally, while  FIG. 1  shows two rafter elements  140  attached to the Peak element via a single peak connecting element  150 , an acceptable alternative is for each rafter element  140  to attach to the peak element  160  by its own peak connector element  150 . In such an embodiment, the example four rafter elements  140  in  FIG. 1  would attach to the peak element by four peak connector elements. Such a design may be advantageous in some cases where staggered rafter elements would be preferred. In all cases, rafter element  140  and peak element  160  may be secured to the peak connector element  150  via a locking mechanism, a clamp mechanism, a strap mechanism, a set screw, or the like. 
     The roof material can be made from any practical material, e.g. polymer, fabric, metal, wood, etc. However, due to cost, strength, and ease of use, a polymer, fabric, or polymer/fabric blend, such as in a tarpaulin, is ideal. Specific materials include polyethylene, canvas, vinyl, silnylon, nylon, cotton, etc. Thickness of the material can influence strength and weather resistance. For example, materials for the roof can be from ˜5 mils to over 16 mils in thickness. Attachment of the roof to the frame  10  can be done via a number of mechanisms. The roof material can have grommets incorporated into its material, which are then used to connect the roof to the frame  10  via cables, ties, elastic bands, rubber straps, metal clasps, elastic cord ball ties, etc. Alternatively, some embodiments may have hooks or other latching elements on one or more of the transverse element  130 , the vertical element  110  or the connector element  120 . These optional latching elements can be used directly connect to the roof or may provide a latching point for cables, ties, elastic bands, rubber straps, metal clasps, etc. to latch to the frame  10 . 
     As noted above, the present design is easily transportable and provides protection for vehicles from the elements. Further, because the design utilizes the car&#39;s own weight to stabilize and secure the frame, it doesn&#39;t need to be secured to the ground via cables, stakes, sandbags, or other mechanisms.

     The embodiment comprises four anchor plates, B, made of “diamond plate” aluminum with aluminum, iron, or steel tubing foot pad, E, to connect to the cast iron vertical “leg” elements, D. The legs can be cut to any desired length, but it is recommended that with side heights greater than 8′, the tubing diameter should be increased to at least1⅜″. In the case where the legs are longer than 5′, it is advantageous for portability to have each leg composed of several sections that are able to be connected together via typically known means, such as sleeving, clips, set screws, screw threads, etc. The legs attach to the transverse elements, also described as the outer and center roof ridges, C and F, via a four-sleeve, cast iron pipe fitting, labeled as a vertical connector, I. The I pipe fitting is a modified T-shape with an additional connector angled to the pitch of the roof (see also  FIG. 5 ). 
     Each I connects a leg element to two sections of the transverse element, an outer transverse element, F, and an inner transverse element, C. In the case where the transverse element is longer than 5′, it is advantageous for portability to have each transverse element composed of several sections that are able to be connected together via typically known means, such as sleeving, clips, set screws, screw threads, etc. The outer and inner transverse elements, F and C may be secured to the connector element I via a set screw or, if threaded, by screwing into the connector. Alternatively, if the connector element is oversized, the roof ridge elements may be connected to each other via set screw, screw threads, sleeving, etc., and the connector element simply connects the roof ridge to the legs. Outer transverse elements may be fitted with end caps, G, made of any material, but advantageously from a material such as rubber or plastic. 
     Connector I is further linked to the roof rafters, A, which attach to the peak connector element, H, in this embodiment a four-sleeve pipe fitting. The peak connector element H connects two roof rafters, A, and outer and inner peak elements, C′ and F′. As in the case of the transverse elements, the peak elements may be secured to the connector element H via a set screw or, if threaded, by screwing into the connector. Alternatively, if the connector element is oversized, the peak elements may be connected to each other via set screw, screw threads, sleeving, etc., and the peak connector element, H, simply connects the peak elements to the rafters, A. 
     Over the entire roof area is placed a tarp made of plastic, fabric or other weatherproof material. The tarp may have eyelets and can be secured via any ordinary means, such as ties, hook and eye, screws, bolts, etc. ( FIG. 2 ,  210 ). In some cases, especially where there is the chance of severe weather conditions, plastic of fabric, or other weatherproof material may be added as side, front and rear “walls.” As with the roof, the walls may have eyelets and can be secured via any ordinary means, such as ties, hook and eye, screws, bolts, etc.

Summary:
A portable or moveable carport is described. The carport as described herein is able to be quickly and easily set up and taken down while still shielding a vehicle from rain, snow and sun—the primary destroyers of automotive paint, body and interiors. The structure has at least four vertical legs supporting an A-frame roof structure. The vertical legs are anchored under the vehicle&#39;s four tires with adjustable plates which can be driven onto once the structure is assembled.
