Description

BACKGROUND OF INVENTION

Field of the Invention

The present invention relates to a vehicle rooftop cargo carrier and in particular, a collapsible semi-rigid carrier that is readily assembled and disassembled.

A rooftop cargo carrier provides extra luggage space for a vehicle, and is normally secured to the vehicle's luggage rack via rooftop attachment hardware. Since a rooftop cargo carrier is rather large and bulky, it can be difficult to store when removed from the vehicle, particularly if space is limited in a storage area.

Conventional cargo and luggage carriers mount to particular dedicated vehicle roof-tops as well as trunks and trailers and are typically built out of heavy, rigid construction materials. Such vehicle cargo carriers are bulky, difficult to ship, and rarely designed for knock down disassembly. The few knock down designs generally have complicated assembly processes utilizing numerous of components and fasteners, many of which are loose, tools and tedious steps.

Conventional cargo carriers further require dedicated fastener mechanisms for particular rooftop fixtures and applications, often lacking adaptability to other types of surface fixtures or cargo.

Additionally, storage of conventional rigid cargo carrier system are cumbersome and entail considerable space and effort to store.

Such rigid and heavy cargo carrier systems are also burdensome and expensive to ship.

Due to such and other drawbacks and problems with prior art rooftop carrier systems, there exists a persisting need for a lightweight, versatile, durable and waterproof vehicle rooftop carrier system that is easily assembled and disassembled for efficacious shipping and compact storage when not in use.

SUMMARY OF THE INVENTION

In view of the foregoing background, an object of the present invention is to provide a semi-rigid rooftop cargo carrier and method employing straightfront and streamlined steps for its assembly and disassembly. The present rooftop cargo carrier is composed of pliable, lightweight, durable and waterproof materials adaptable and is adaptable for mounting to various vehicle rooftop fixtures and collapsible to a compact configuration for ease of storage and reducing shipping cost to customers and risk of damage during shipping.

These and other objects, advantages and features in accordance with the present invention are provided by the present cargo carrier's innovative configuration including end members and at least two elongate side members preferably equipped with extendible push bars (“EPB”) each including first and second side arm members securably engagable for lengthwise, extended alignment to thereby simultaneously mount the collapsible frame into upright, open position whereby the pliable shell is tensionablly mounted about the frame to thereby readily assemble the semi-rigid cargo carrier according to the present invention.

The pliable shell of the present invention utilizes a flexible sheet material having a waterproof surface. Although numerous types of fabric sheeting providing the aforementioned properties can be used to formulate the pliable shell according to the present invention, the description of the present invention will focus on use of a vinyl coated polyester polymer, as this material is readily available on the market, low cost and readily configurable to stretch about and tension fit the underlying frame. It is understood that many substitute materials including nylon, rubberized and various flexible polypropylene or similar waterproof sheeting fabrics can also be used to provide the features of the present invention.

The pliable shell according to the present invention is sized and configured for tensionable mounting about the collapsible frame such that pivoting the at least two opposing elongate side members to engage with corresponding upper corners of the at least two end members tensionably mounts the pliable shell into taut alignment about the collapsible frame whereby the opposing tension exerted between the pliable shell and the collapsible frame maintains the semi-rigid cargo carrier in an assembled position.

The semi-rigid cargo carrier according to the present invention employs a collapsible frame at least two end members which preferably include an upper longitudinal bar and a lower longitudinal bar connected by at least two opposing cross bars to form upper corners and lower corners along a substantially planar orientation at a substantially perpendicular or slightly obtuse angle with the upper and lower longitudinal bars. According to the present invention, the at least two elongate side members have opposing ends pivotally connected to corresponding upper corners of the at least two end members, and a pliable shell sized and configured for tensionable mounting about the collapsible frame such that outwardly pivoting the front and rear ends away from at least two opposing elongate side members sets the collapsible frame into an upright position and mounts the pliable shell into taut alignment whereby the opposing force exerted between the pliable shell and the collapsible frame sets the semi-rigid cargo carrier in an assembled position. In a preferred embodiment, the at least two elongate side members are oriented at a substantially perpendicular angle with the end members so as to form a substantially rectangular configuration along an upper surface when the pliable shell is mounted and thus the semi-rigid cargo carrier is in the assembled position.

In particularly preferred embodiments, the at least two elongate side members each have a first side arm member and a second side arm member each having fastenable ends securable into abutted engagement by an EPB securing mechanism to thereby extend the first side arm member and second side arm member in linear alignment along their respective longitudinal axes such that outward thrust exerted by the at least two elongate side members against corresponding upper corners of the end members simultaneously sets the collapsible frame in the upright position and tensionably mounts the pliable shell thereupon.

In particularly preferred embodiments, the EPB securing mechanism comprises a channel portion affixed to a fastenable end of each of the first side arm members of the elongate side members configured for receiving the corresponding fastenable ends of the second side arm members of the elongate side members. Such embodiments may employ a spring button on a fastenable end of the second side arm for engaging the channel portion of the EPB securing mechanism to thereby secure the at least two elongate members in abutted engagement member so as to pivot upper corners of corresponding end members into substantially perpendicular alignment with the end members so as to position the collapsible frame in the assembled position.

In particularly preferred embodiments, the elongate side members are oriented at a substantially perpendicular angle with the end members to form a substantially rectangular configuration when the semi-rigid cargo carrier is in the assembled position and further comprising three way barrel fasteners with a hinge whereby the first and second arm members hinge inwardly to nest next to corresponding end members. Preferred embodiments of the present invention further comprise a closeable side opening that is preferably a zipper wherethrough the EPB securing mechanim is accessed for engaging a channel portion configured for receiving the corresponding fastenable ends of the second side arm member of each of the elongate side members thereby detachably fastening the fastenable ends of the first side arm member and the second side arm member into abutted engagement so as to secure the at least two elongate side members in extended linear alignment along their respective longitudinal axes and pivoting the elongate side members so as to position the collapsible frame in the assembled position.

A yet further feature of the present invention is a third elongate side member having a pivot end detachably mountable to an upper longitudinal bar between the at least two side members and a fastenable end detachably mountable to an upper longitudinal bar between the at least two side members when the semi-rigid cargo carrier is in the assembled position. The third side member has an EPB for securing the support bar in an extended aligned position when the semi-rigid cargo carrier is in assembled position.

Further provided by the present invention is a method for assembling a semi-rigid cargo carrier, comprising the steps of providing two opposing end members with an upper longitudinal bar and a lower longitudinal bar connected by at least two opposing cross bars to form upper corners and lower corners along a substantially planar orientation at a substantially perpendicular or slightly obtuse angle with the upper and lower longitudinal bars connected in perpendicular orientation to at least two opposing elongate side members comprising a first side arm member and a second side arm member having a fastenable ends for abutted engagement in an EPB securing mechanism to extend the at least two elongate side members into extended alignment and a pliable shell sized and configured for mounted tensionable seating about the collapsible frame, wherein the pliable shell has at least two closeable side openings for accessing the first and second side arm members of the at least two elongate side members. The next step of the present method for assembling the semi-rigid cargo carrier is opening the closeable side opening to acces the first bar and second bar of each of the at least two elongate side members, fastening the EPB securing mechanism to extend each of the at least two elongate side members into extended position whereby opposing outward thrust exerted against corresponding upper corners of the end members simultaneously opens the collapsibe frame into an upright position pivoting the pivot ends of the at least two opposing elongate side members to engage with corresponding upper corners of the at least two end members so as to mount the pliable shell into taut alignment whereby the opposing tension pliable shell and the collapsible frame maintains the semi-rigid cargo carrier in an assembled position; and closing the closeable side opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. Now referring to FIG. 1, there is shown a perspective view of semi-rigid cargo carrier 10 with the enclosed collapsible frame 20 tautly enclosed within corresponding pliable shell 12.

Pliable shell 12 is composed of a pliable and durable, waterproof sheet material. In a preferred embodiment, pliable shell 12 is a vinyl coated polyester polymer, which is commercially available and readily configurable to stretch about and tension fit the underlying frame 20. It is understood that many substitute materials including nylon, carbon fiber and various flexible polypropylene fabrics can also be used to provide the features of the present invention.

Pliable shell 12 is sized and configured for tensioned seating about collapsible frame 20 as shown in FIGS. 1 and 6. In particularly preferred embodiments, the length of the section of pliable shell 12 configured for seating along the perimeter lines formed by elongate side members 6 is about 0.5 inches (1.25 cm) shorter than the length of the perimeter line in extended position to facilitate an appropriate extent of tension when in mounted position.

Now referring to FIGS. 2-4, collapsible frame 20 includes front end member 2 and rear end member 4 comprising two opposing upper and lower bars and opposing side bars affixed thereto at a substantially perpendicular or slightly obtuse angle such that the lower ends extend about one half inch (1.35 cm) beyond respective ends of the upper bars of front end member 2 and rear end member 4 detachably secured to two opposing elongate side members 6 that are detachably secured by front and rear pivot fasteners 5 pivotally connecting respective ends of elongate side members 6 for inward folding to nest by upper bars of corresponding front end member 2 and rear end member 4 to collapse down into a flat position as illustrated in FIG. 3. A particularly preferred embodiment of the present invention shown in FIG. 6 utilizes a spring lock 7 to secure the fastener when opened to a position that is substantially perpendicular along a longitudinal axis to the upper surface of the front and end members, which are preferably rectangular frame cross panels. It is understood that the fasteners are not limited by this description and that any fastener or connection means may be utilized to connect the extendible side push bars and front and rear rectangular frame cross panels.

A particularly preferred embodiment of the present invention shown in FIGS. 5 and 6 further includes opposing elongate side members 6 employing of EPBs accessed through zippered closeable side opening 16 including zipper edge members 16A and 16b configured to extend in a longitudinal direction along shell 12 such that it coextends along elongate side member 6A when zippered on collapsible frame 20 when in an open, assembled position. To assemble the semi-rigid rooftop cargo carrier, a user reaches through closeable side opening 16, to grasp a first side arm member 6A and side arm member 6B and inserts an end of first side arm member 6A into a corresponding end of side arm member 6B and thereby engages a corresponding side arm member 6B to secure the EPB securing mechanism 6C such that elongate side member is extendably aligned and the force applied tensionably mounts the pliable shell 12 about collapsible frame 20 in a fitted assembled open position as illustrated in FIG. 1. When first side arm member 6A and second side arm member 6B are secured by EPB securing mechanism 6C into an abutted longitudinal alignment, the extension of elongate side member 6 exerts thrust against the corresponding upper corners of front end member 2 and rear end member 4 to thereby simultaneously set collapsible frame 20 upright and tensionably mount pliable shell 12 on collapsible frame 20 such that angled edges and corners are aligned and taut to facilitate ready assembly of the semi-rigid rooftop cargo carrier 10 to adapt a shape in conformance with collapsible frame 20.

As illustrated in FIGS. 1 and 5, pliable shell 12 yet further includes zippered side openings 16 disposed along the longitudinal top seam of pliable shell 12 adjacent to elongate side members 6 wherethrough a user can access elongate side member 6 components and thereby insert side arm member 6A into EPB securing mechanism 6C on an end of corresponding side arm member 6B to then straighten and extend them into secured abutted linear alignment. The outward force exerted when extending elongate side member 6 into open position engages pivotable corner fasteners 3 and thereby locks opposing elongate side members 6 and opposing upper corners of front end member 2 and rear end member 4 into open, assembled position. Thus extending elongate side members 6 to set frame 10 into an open, upright position simultaneously exerts pressure on pliable shell 12 in a direction to mount pliable shell 12 about frame 20 without requiring tools and minimal shifting of pliable shell 12 in order to couple it onto corresponding portions of collapsible frame 20

Closeable side openings 16 include perimeter zipper edge members 16A and 16B along which corresponding flexible strips of a zipper of other equivalent fastener mechanism are affixed so as interlocking projections extend along an inner surfaces of perimeter edges 16A and 16B extending from outer perimeter of closeable side opening 16. In a particularly preferred embodiment of the present invention, the fastener mechanism is a water resistant zipper of which is corresponding strips are contiguously attached along a perimeter edge 16A and perimeter edge 16B so they can be continuously interlocked along closeable opening 16 to seal out rain and other elements when cargo carrier 10 is assembled. Alternative embodiments may employ equivalent closure mechanisms such as, for example, an interlocking groove and ridge.

The latter procedural steps are reversed for disassembly of cargo carrier 10. That is, closeable side opening 16 is unzipped and reached through to access elongate side arm members 6A and 6B and disengage EPB securing mechanism 6C. Then, first side arm member 6A and second side arm member 6B are disengaged, pivoted to fold inwardly to rest by corresponding end members 2 and 4 respectively. Pliable shell 10 is then neatly folded about the collapsed frame for compact storage.

In a particularly preferred embodiment illustrated in FIGS. 1 and 2, an additional feature of mounting at least one third elongate side member 8 in parallel alignment along a substantially longitudinal axis between the two elongate side members. Third elongate side member 8 may be further provided with an EPB securing mechanism 8A to facilitate expedited assembly and disassembly as well as compact storage. Third elongate side member 8 protects cargo carrier 10 and objects therein from potential damage from debris, snow and other objects or elements that descend and collide with cargo carrier 10.

Semi-rigid rooftop carrier 10 may be further provided with straps adaptable to various rooftop fixtures of a vehicle, as shown in FIG. 7. Alternative embodiments may employ various fasteners, including, for example, clamps and channel locks to secure the rooftop cargo carrier 10 to the relevant vehicle fixture.

The streamlined and self-contained construct of cargo carrier 10 provides numerous advantages over the prior art including facile and quick assembly and disassembly. Particular advantages are that no tools or loose components, such as, for example, fasteners screws, which can be misplaced and difficult to gather.

A yet further advantage is the lightweight and compact form when disassembled minimizing the cubic feet required to ship, move and store the structure. Even when extended in assembled position, the relatively lightweight and semi-rigid form of the cargo carrier according to the present invention render it readily grasped and inserted in a confined area.

In addition to being lightweight and durable, the facile construct of the present cargo carrier imparts unique mechanical and aerodynamic characteristics that make it aesthetically and mechanically compatible with a vehicle exterior imparting it with stability and aerodynamic characterics rendering it robust in windy conditions or under heavy weighting from snow loads. The semi-rigid composition of the pliable shell and frame matrix thus imparts pliability and strength providing the above and other advantages.

While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the invention as claimed.
