Description

CROSS-REFERENCE TO RELATED APPLICATION

This U.S. patent application claims priority to U.S. Non-provisional application: Ser. No. 16/882,404 filed May 22, 2020 which claims priority to U.S. Provisional Application 62/851,429 filed May 22, 2019, the disclosure of which is considered part of the disclosure of this application and is hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

This invention generally relates to roof rack and load carrier for a vehicle, especially a low-profile system that allows a user to easily load and unload the rack system.

BACKGROUND

In the automotive industry, vehicles utilizing load carrier systems, such as roof-top carriers are very common for increasing the capacity of the items to be transported, as well as carrying larger cargo, such as kayaks, canoes, bicycles, and other equipment.
The disadvantage of conventional roof racks that are mountable on the roof is that the luggage or the roof box must be lifted onto the roof and fixed there. This is particularly difficult and arduous when the objects are heavy, bulky, and oversized. Roof racks have therefore been suggested with devices for making it easier to convey luggage or a load onto the roof. For example, German laid-open patent application DE 41 22 823 A1 and German utility model DE 200 02 018 U1 propose roof racks with a lifting device. The disadvantage of these movable roof racks is that they possess significant additional weight and take up additional space on the roof of a motor vehicle. The air resistance and fuel consumption are thereby increased.
In a similar manner, U.S. Pat. No. 5,154,563 and DE 44 21 030 C1 disclose movable roof racks where a track system is installed on the outside of the motor vehicle that runs down from the roof to the rear or side of the motor vehicle. Roof boxes or other containers can move along this track system. This yields significantly elevated air resistance and fuel consumption in this case as well. Furthermore, the luggage containers installed on the tracks are tilted while they move so that the pieces of luggage in the luggage containers get mixed up and/or can become damaged.
There exists a need for an apparatus and method that reduces the physical strength and effort required to load cargo onto a roof-top cargo rack or carrier.

BRIEF SUMMARY OF THE INVENTION

In one aspect, this disclosure is related to a moveable roof rack assembly to easily access and utilize cargo stored and placed on the rack without having to climb on top of the vehicle to secure or remove the cargo.

FIGS. 1A-G show a various views of a retractable load carrier 100 for use on a vehicle roof of the present disclosure. The retractable load carrier 100 can include a rack assembly 200 and a rail assembly 300. The full rack can be fully assembled in any suitable manner such as using coupling means or welded together as a singular component. Alternatively, the rack assembly 200 can be comprised of various components and using any suitable coupling means, such as fasteners to allow a user to break down, thereby reducing the rack size for storage. In some embodiments, the rack assembly 200 can include one or more hinges to allow the rack to be folded when detached from the rail system. The hinges can allow the rack to be folded over on to itself to further reduce the size and footprint of the rack allowing for easier storage of the rack assembly when not in use. Similarly, the rack assembly 200 can use quick disconnects to break down the rack portion into smaller components.
In one exemplary embodiment, the load carrier system can include a rail assembly 300 to be mounted to the roof of a vehicle. The rail assembly 300 can be removeable mounted using any suitable means, such as fasteners or adhesives. The rail assembly 300 can include one or more rails 301 that can take any suitable shape and configuration. In one exemplary embodiment, the rail 301 can have a curvature bend that can approximate the curve of the roof of the vehicle to which the system is to be mounted. Similarly, the curvature of the rail assembly 300 can allow for easier access to the rack assembly 200 that can extend in an outwardly and downward position when in an extended position as shown in FIGS. 1A-G. In one exemplary embodiment, the curvature/arc can be about 4.5 to about 9.5 inches, or about 5.5 to about 8.5 inches, or about 7.5 inches spaced away from the top of the vehicle roof to the apex of the curvature of the rack assembly 300.
The rail 301 can have a first side 303 and a second side 305. The first side of the rail can face a downward direction toward the roof. The sides of the rails can be flat or curved in configuration. The second side of the rail can face upward. The second side can be any suitable configuration. In one exemplary embodiment as shown in FIG. 3 , the second side can be configured in a U-shaped have a first side wall 307 and a second side wall 309. In some exemplary embodiments, the two sidewalls can be a locking receiving means, such as a grooved body 311. Similarly, there can be center position portion 313 that separates the first side and second side of the rail. A configuration can take the form of I-shape, H channel, or any suitable rail configuration, wherein there is a recessed area 315 formed on each side of the center member of the rail. Each rail can have a first end 317 and a second end. In some exemplary embodiments, the grooves 312 of the grooved member 311 can be opposite between the first end 317 and the second end 319.
The recessed areas can be used to interface with a rack assembly 200. The rack assembly can comprise a first support member 201 a and second support member 201 b generally parallel to each other and coupled together using one or more cross-members 203. The support members 201 a, b can correspond to a respective rails 301 of the rail assembly 300. The support members 201 can have a first face 205 that is generally flat in configuration. The first face can have a first end and a second end, wherein a respective first and second sidewall 207 can extend from the first end and a second side wall can extend downward generally along a vertical plane to form a u-shaped support member having an interior portion as shown in FIG. 3 . Proximate to the bottom end of one or more of the side walls 207 an interfacing member 209 can extend inward from each side wall towards the center of the interior portion of the support member. The interfacing members 209 can be any suitable means. In one exemplary embodiment, the interfacing means can comprise a post having a bearing member, such as a ball bearing or a polymer roller 211 to allow for easy movement of the rack assembly along the rail system. The interfacing members 209 can interface with the recessed portions of the rails. This interfacing limits vertical movement of the rack assembly with respect to the rails, while also ensuring smooth movement of the rack assembly on the rails. In some exemplary embodiments the interfacing member and roller portion can be a single unit.
Top side of the rail can include a latch engagement means 213, such as a grooved portion. The grooves of the grooved portion can engage with one or more latches of a locking means. In one exemplary embodiment, the grooves can face a first direction on one side of the rail and second direction on the other half of the rail as shown in FIGS. 2A-2B. The grooves on the first half of the rail can widen on the right and similarly, the other half of the rail can include grooves that widen to the left. As the rack assembly 200 is in motion the handle assembly 220 can engage the locking mechanism 250 either manually or by an assisted motion device such as pneumatic, piston, motor or spring. The handle assembly 220 can be attached to the locking mechanism 250 and used to engage or disengage latching engagement means 213, which can include but is not limited to one or more latches or pins mounted on the support members 201 of the rack assembly 200. The handle assembly 200 can be coupled to the locking assembly using any suitable means. In some exemplary embodiments, a cable or rod can be used to couple the locking assembly to the handle assembly.
The locking mechanism 250 can include one or more cables 251 that run to the various latches 213 or pins of the rack assembly. The cables can be supported using one or more cable guides 253. The latches or pins can be mounted within the interior portion of the support members. In some exemplary embodiments, a rotatable latch member 217 can extend between the two side walls of the support member. The latch member 217 can contain at least one latch 213 corresponding. In some exemplary embodiment, the latches on a single rotatable latch member 217 can only correspond to directional grooved 312 of the grooved body 311. A tensioning means 221, such as a spring, can be coupled to the latch or pin and cross member to maintain pressure against the latch or pin and keep the latch or pin in an “engaged” state against the grooved portion of the rail or pinion. The cables 251 can be ran through the guides 253 using cable guides. One or more cables can be connected to or coupled to the latch or pin and configured to raise the latch off of the grooved portion or retract pin from pinion when engaged by the handle assembly 220 of the rack assembly 200.
Additionally, there can be two sets of pinions latches that are offset from each other in opposite rails 301 as shown in FIGS. 2 and 3 . The first set of latches pins can engage a pinion grooved members 312 corresponding to one half of the rail system, while the second set of latches is configured to engage grooved members corresponding of the other half of the rail system. In some exemplary embodiments, the rack assembly 200 can have a first end and a second end. Each end of the rack assembly can have a handle portion. The handle portion on each end can correspond to one set of the latches. The handle portion 220 on one side corresponds to the first both pins set of latches, while the hand portion on the other side also corresponds to the both pins second set of latches. When the handle portion 220 b is squeezed or unlocked, as shown on one end in FIG. 5 , the handle pulls a cable coupled to the various latches or pins thereby disengaging the latches or pins from the respective grooves or pinions and allowing the rack assembly to move in the direction of the respective handle portion. When the handle portion is released, the tension is supplied by one or more springs in relation to the latches or pins to engage the latches with the grooves or pins with the pinions. The opposite set of latches that do not correspond to the handle that is being engaged by the user can “skate” or “slide” over the grooves of the rail and will not impede the movement of the rack assembly along the rails.
The pinions or grooves of the rails can be spaced in predetermined intervals which allow the rack assembly to be stopped or placed in a number of positions along the curved linear rail including the retracted, up, and stored position and the fully extended position down position, shown In FIGS. 2 and 5 . In the fully extended position the rack assembly will have a minimum viable amount of material remaining in the linear rail of the first part to allow for the determined weight to be supported over the side of the vehicle. A second handle on the opposite side of the rack assembly can operate in the same manner and correspond to the second set of latches or pins. At any point along the linear rail there can be a number of latch or pin assemblies configured to interface with a latch or pin when the handle is engaged. When the handle is disengaged the rack assembly can move freely along the rails.
As shown in FIGS. 6, 7 and 15 , some exemplary embodiments of the handle assembly 220 can include a handle portion 223 and one or more biasing apparatuses 225. In one exemplary embodiment, the biasing apparatus 225 can be a spring configured to maintain the handle portion 223 in a first position when not in engaged. In some embodiments, the first position can be a locked position. As shown in FIG. 9 , some exemplary embodiments can include one or more coordinating engagement cable 257 that can allow a user to disengage the locking mechanism of both locking apparatuses 250 on each end of the rack assembly 200. This can allow a user to easily disengage the locking apparatuses 250 a, b located on each end of the rack assembly on one end without the need of walking over to the other side to disengage the locking apparatus 250. When a user squeezes or applies pressure to the handle portion 223 and provides more force than that applied by the biasing apparatus 225, one or more cables 251 coupled to the handle can then disengage the locking mechanism.
Some embodiments of the handle assembly 220 can include one or more pulleys 227 to guide the cables 251 and aid in disengaging the locking mechanism. When a user releases the handle portion 223, the biasing apparatus 225 then allows the latches to reengage the rail. The pulleys 227 can allow for and provide direction to the cables 251 coupled from the handle portion to the various latches or pins. In one exemplary embodiment, the cable 251 can be coupled directly to the handle portion at a coupling end and travel through a first pully 227 b proximate to the handle and a second pulley proximate to the edge of the rack assembly 227 a. A cable 251 can travel around a portion of the first pulley and through the second pully to a guiding member 253 to guide the cable 251 up a portion of the rack assembly to the desired latch or pin 213. A second set of pulleys can be located on the other side of the handle and correspond to latches or pins on the other side of the rack assembly. This handle locking assembly can allow for multiple cables 251 to be coupled to either end of the handle portion and corresponding to the respective sides of the rack assembly and the latches or pins located on each side of the rack assembly 200.
The two curved linear rails of the rail assembly can be spaced apart at a predetermined distance from each other with supporting bars arranged between them to provide structural integrity. The rack assembly 200 can include antifriction members that are contained within the recessed areas of the rail system part which permit movement along the curved linear rail. The two curved linear rails 301 and supporting bars 201 can interface with each other using any suitable means, such as the interfacing means 209 of the rack assembly with the configuration of the rail side walls. Additionally, the rails 301 can include one or more mounting members that are pre-existing on the vehicle 10 or mounted to the vehicle to allow for easy removal of the entire rail assembly 300 and rack assembly 200.
In some exemplary embodiments, the two curved linear rails 301 can be couple to create a structure that is mounted to a vehicle roof. The linear rail 301 can utilize an antifriction member to allow the rack to extend out over the side of the vehicle when the handle portion is activated to disengage the locking means. The rack assembly 200 can then progress along the rail assembly 300 until the handle/grip 223 is released thereby reengaging the locking mechanism of the locking assembly 250. As shown in FIG. 5 , the rack assembly 200 can include one or more cross members 203, that can allow a user to attach one or more items to the rack assembly 200 as well as strengthen the rigidity of the rack assembly 200. Additionally, the end of the rails 301 can include a stopping means, such as a bump stop to interface with the end portion of the support members to prevent the rack assembly from completely sliding off of the rail system. In other embodiments, a cable 271 can limit the outward mobility of the rack assembly by only having a pre-determined length of travel due to the cable length. When the handle portion 223 is released it is configured to lock the rack in motion at the next available locking position of a grooved member of the locking assembly 250.
To support movement from the up and locked starting position to extended and extended to up and locked position springs, actuators, pneumatics, and or motor(s) may be provided. In its fully extended state, the rack can be supported by at minimum two latches or pins interfacing with the pinion or grooved portion of the rails 301 can support the rack assembly 200 and any contents supported by the rack assembly 200. In one exemplary embodiment, each rail 301 can have a single latching or pin interfacing point for a total of two latching or pin interfacing points between the two rails. From one mounting position with no reconfiguration or re-mounting the rack movement can extend over the vehicle horizontally over both sides of the vehicle by utilizing the attached handles. In one exemplary embodiment, there can be a handle portion 220 on both sides of the rack assembly 200 to allow a user to move the rack assembly to extend over either side of the vehicle. In some alternative embodiments, the first a second support members can be separate and not coupled together to allow for individual use of each individual support member corresponding with the rail of the rail assembly.
FIG. 8 illustrates an exemplary embodiment of a rack assembly 200 that can include a first support member 201 a and a second support member 201 b. The two support members 201 can be coupled together with one or more cross members 203. In some exemplary embodiments, the cross members 203 can additional be used to support the locking mechanism 250 and handle portion 220 of the rack assembly 200.
As shown in FIGS. 8, 9 and 12-15 some exemplary embodiments of the handle assembly 220 can include a handle portion 223 and one or more biasing apparatuses 225. In one exemplary embodiment, the biasing apparatus 225 can be a spring configured to maintain the handle portion 223 in a first position when not in engaged by a user. In some embodiment, the first position can be unengaged or locked position. When a user squeezes or applies pressure to the handle portion 223 and provides more force than that applied by the biasing apparatus 225, one or more cables 251 coupled to the handle can then disengage a locking mechanism of the locking assembly 250. In some exemplary embodiments, the mechanism can include on or more engagement members or latches 213 to allow a user to easily move the rack into various positions. The engagement members 413 can interface with a grooved member 412 to lock the rack assembly into a desired position. When a user releases the handle portion 223, the biasing apparatus 225 then allows the latches 413 to reengage the grooved member 412. Additionally, the handle locking assembly 220 can include one or more pulleys.
In one exemplary embodiment, the locking mechanism can be a ratchet latch 250 that can include a tension bar 261. The tension bar 261 can span between each of the support members 201 as shown inf FIG. 8 . The bar can have a first 262 end and a second end 264. The tension bar 261 can be set to a certain level of compression or tension using one or more tensioning means, such as a spring. In some exemplary embodiments, the tensioning means 221 can operate as a lift assist by maintaining a tension on the 261 to aid a user when moving the rack assembly 200 from a first position to a second position on the rail assembly 300. In some exemplary embodiments, the tension bar 261 have one or more spool apparatuses 263. In some exemplary embodiments, the tension bar can have two spool apparatuses on each end or a single apparatus on each end.
