## Background
RELATED APPLICATIONS
The present invention was first described in and claims the benefit of U.S. Provisional Application No. 60/816,076, filed Jun. 26, 2006, and U.S. patent application Ser. No. 11/821,661, filed on Jun. 25, 2007, the entire disclosures of which are incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates generally to a novel system to prevent cargo on automobile roof racks from shifting during transport and, more particularly, to the system providing a means for a foam block being covered with a fabric envelope removably attachable to a conventional vehicle rooftop to protect cargo and to protect the vehicle's roof.
BACKGROUND OF THE INVENTION
Pickup trucks, trailers and other moving aids are often called upon for service when moving large, heavy objects. However, there are many times when large and bulky, but relatively lightweight, objects such as tables, chairs, lumber, boxes and even Christmas trees require transportation. Since such objects will not fit inside a typical motor vehicle, many people resort to transporting these items on the roofs of their cars. Since most cars do not come equipped with luggage racks, people may place towels, carpeting, cardboard or other materials to protect the finish of the vehicle roof. It is often observed that such materials slide about when the object is being loaded, which may allow the roof to buckle at the high point in the case of curved roofs and present a danger should the object and protector slide about during transport.
Several attempts have been made in the past to design an apparatus to prevent cargo on automobile roof racks from shifting during transport. U.S. Pat. No. 5,769,291 in the name of Chasan discloses a support pad assembly for carrying articles on a vehicle roof with first and second elongate members each having an upper pad member of cushioning material. A first side bolster is hinged to one side edge of the upper member and a second side bolster is hinged to the opposite side edge of the upper member. Each side bolster has a core of cushioning material and extends along the entire length of the elongate member. The side bolsters are of a rectangular cross-section and have opposing inner faces carrying inter-engageable fasteners for releasably securing the side bolsters together beneath the upper pad member. The two (2) elongate members are secured on spaced crossbars of a vehicle roof rack by placing the upper pad member on top of a roof rack crossbar and engaging the side bolsters beneath the crossbar. At least one (1) tie down strap is secured to one (1) end of each elongate member for securing an elongate item on top of the upper pad member. Unfortunately, this prior art example is not designed to be easily installed or removed from a vehicle.
U.S. Pat. No. 5,607,093 in the name of Geier discloses a carrier device for supporting and securing different objects to a luggage rack of a vehicle or directly to the roof of a vehicle which does not have a luggage rack. The device includes a carrier fabric on which one (1) side is covered along its length with loops and one half (1⁄2) with barbs. The fabric is formed with cushioned straps on one half opposite either the hooks or barbs. The fabric may be placed onto a luggage rack bar across the width of a vehicle, and skis, fishing poles or the like can be secured by the straps to the support carrier. Alternatively, the carrier device may be secured directly to a vehicle roof which does not have a luggage rack. To this end, the carrier device is wrapped around a filler member and end straps with hooks thereon are provided and designed to connect to a vehicle gutter or other part of the vehicle body such as the lip of the roof. Unfortunately, this prior art example is not designed to be compatible with vehicles with a preexisting luggage rack.
U.S. Pat. No. 5,377,889 in the name of Sumino describes an automobile roof carrier mainly composed of a magnetic base portion, a gripping portion for removal, a covering member and a loading article holding portion. The covering member is integrally jointed over the magnetic base portion while the magnetic base portion is covered by the covering member except in the attractive surface of the magnetic base portion and the gripping portion for removal. Combined integrally in the upper part of the covering member is a loading article holding portion which is able to be opened and closed. A supplementary cover which is able to be opened and closed is attached to the covering member so that the gripping portion for removal may be hidden and exposed. There is provided a first locking mechanism for maintaining the closed state of the supplementary cover, whereas there is provided a second locking mechanism for maintaining the closed state of the loading article holding portion. A common key for releasing the locked states of these locking mechanisms is provided. The automobile roof carrier of the invention further includes means for preventing the degradation of appearance, increment of air flow resistance at driving, and the reduction of contacting area with the roof and the like. Unfortunately, this prior art example provides for a permanent fixture to an automobile roof, and is therefore not designed to be easily installed and removed.
None of the prior art particularly describes a novel system to prevent cargo on automobile roof racks from shifting during transport and, more particularly, to the system providing a means for a foam block being covered with a fabric envelope removably attachable to a conventional vehicle rooftop to protect cargo and to protect the vehicle's roof. Accordingly, there is a need for a means by which large, bulky, but lightweight objects can be safely transported on the roof of a motor vehicle without damaging the roof or causing other problems as listed above. The present invention is simple to use, inexpensive, and designed for many years of repeated use.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the prior art, it has been observed that there is need for a novel system to prevent cargo on automobile roof racks from shifting during transport comprised of a trapezoidal foam block covered with a fabric envelope and removably attachable to the vehicle rooftop.
The invention as presently conceived is a foam block attachable to conventional vehicle rooftop carriage racks to protect cargo and the vehicle's roof from damage during transport. The device comprises a foam block that is generally trapezoidal in shape and which is sufficiently flexible to conform to the curvature of the vehicle's roof. The system is envisioned to be introduced in a pair of units. A tube provides form-fitting covering of the foam padding. The system further comprises a plurality of extensions integrally sewn to opposing end portions of the tube along a top outer edge to allow for secure fastening of the system to a vehicle. Each extension comprises a fastening loop portion which allows a user to route a rigging member such as a ratcheting tie-down, a rope, a cord, or the like through the loop portion to secure the system.
The block further comprises an integral first ear portion at a proximal end and an integral second ear portion at a distal end. The first ear portion and the second ear portion are constructed of a similar material to the block and extend outwardly from and coplanar with a bottom surface of the block. The first ear portion and the second ear portion provide a protective padding to window openings of the vehicle during use of the system. The first ear portion and the second ear portion further provide attachment to the fabric envelope.
The fabric envelope is removably attachable to the block to facilitate cleaning, servicing, and replacement. The fabric envelope is envisioned to be introduced in a variety of decorative colors and patterns and may contain various indicia such as logos, messages, script, or the like.
The method of installing and utilizing the system may be achieved by procuring an instance of the system having a desired length, color, and indicia; inserting the foam block into the fabric envelope, if not previously installed; inserting the ear portions of the block through respective anchoring loop portions of the extensions; opening door or window portions of the vehicle; positioning the system on a rooftop portion of the vehicle at a desired location; positioning the extensions so as to be suspended on each side downwardly over a window opening; securing the system to the vehicle by routing at least one (1) rigging member through the fastening loop portions of the first extension; routing the rigging member through the fastening loop portions of the second extension; routing the rigging member across an interior ceiling portion of the vehicle; latching and tightening the rigging member if utilizing a tie-down device or tying the rigging member if utilizing rope, cord, or the like to secure the system; installing a second rigging member as previously described by utilizing the remaining fastening loops as needed; installing additional units of the system along a roof portion of the vehicle as described above as needed based upon an anticipated cargo to be loaded; placing a quantity of cargo or other similar items to be transported upon the system; securing the cargo by using additional rigging members as required to stabilize the cargo; transporting the cargo to a destination in a normal manner; removing the rigging members and removing the cargo from the system; removing the rigging members; removing and storing the system until again needed; and, benefiting from a protective, safe, and easily installed system for transporting cargo using a vehicle.
