Description

Atty Ref. No.: 2025-846-01359-JBLRACKED MODULAR BAY AND SWING-ARM VEHICLE HITCH PLATFORM CROSS REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Patent Application No.63 / 720,247, filed Nov. 14, 2024, titled “Modular Hitch Rack System,” the entirety of which is incorporated by reference.FIELD OF THE INVENTION

[0002] This disclosure relates to modular rack systems and vehicle-mounted hitch rack platforms for transporting, storing, and supporting equipment and accessories. In various embodiments, a base structure engages a vehicle hitch receiver and supports interchangeable modules that can swing or rotate between stowed and deployed positions to maintain access to the rear of the vehicle while carrying cargo or task-specific components.BACKGROUND

[0003] Racked systems and vehicle-mounted hitch platforms are used to transport, store, and support equipment and accessories in consumer, commercial, and industrial settings.Conventional solutions include fixed cargo carriers, swing-out frames, and task-specific racks. While these products can move payloads, they often introduce practical and serviceability challenges.

[0004] Many existing hitch-mounted platforms obstruct access to rear vehicle areas when loaded, or they provide only a single open position without positive stops for intermediate use. In some cases, latching hardware is not optimized for repeated field use, which can complicate securing the platform for travel. Load retention can also be limited when tie-down patterns are sparse or not aligned with common cargo shapes, making it harder to route straps reliably.

[0005] Similarly, modular rack and bay systems for equipment often depend on tool-based fasteners and loose alignment tolerances that complicate installation and removal. Blind-mate electrical or data connections can be difficult to align repeatably, and cable management addons may increase bulk or interfere with servicing. Vibration transmission and airflow constraints can degrade the performance or longevity of equipment mounted in these racks.Atty Ref. No.: 2025-846-01359-JBL

[0006] Therefore, there remains a need for systems that: (i) provide stable, repeatable alignment during insertion and removal, (ii) allow selective movement between closed, intermediate, and fully open positions with positive retention, (iii) support secure load restraint using versatile tie-down matrices or equivalent features, and (iv) facilitate quick, tool-limited servicing while accommodating power and data interfacing where required. Such systems should maintain rear-of-vehicle access, improve safety and usability in the field, and reduce time and effort associated with installation, reconfiguration, and maintenance.SUMMARY OF THE INVENTION

[0007] The following summary is provided to introduce, in a simplified form, selected concepts that are further described in the detailed description below. This summary is not intended to identify all key or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0008] In one aspect, a racked modular system includes a rack frame with opposing guide rails that define a bay, a module sized to slide along the rails, a locating interface that constrains at least pitch and yaw at a seated position, and a quick-release latch arranged to draw the module into the seated position without tools. A backplane at the rear of the bay provides a blind-mate electrical connector aligned to couple with a corresponding connector on the module as the module seats. Optional features include a floating mounting arrangement for the connector to accommodate tolerance variation, vibration isolation between the module and the rails, an airflow shroud, a safety interlock that interrupts power when unlatched, and a latch state sensor for telemetry or control.

[0009] In another aspect, a module for installation in such a system includes a chassis, an alignment interface that cooperates with a complementary interface of the rack frame to maintain repeatable positioning, a connector configured for blind-mating at the seated position, and a quick-release latch with an over-center action. The module can include an ejection lever to initiate extraction and may carry electronics or mechanical components that benefit from the repeatable alignment and serviceability provided by the rack.

[0066] Options and substitutions. Features described in connection with any embodiment may be combined with features of any other embodiment where structurally compatible. Optional features may be omitted unless explicitly required by a given claim. References to examples or embodiments are non-limiting.

[0067] Materials and finishes. Structural members may be formed from steel (e.g., low-alloy, stainless), aluminum alloys, titanium, magnesium, fiber-reinforced composites, engineering polymers (e.g., nylon, acetal, polycarbonate, PBT), or combinations thereof. Surface treatments can include powder coat, paint, anodize, e-coat, plating, passivation, or conversion coatings suited to outdoor and corrosive environments.

[0068] Manufacturing. Components may be made by stamping, laser cutting, water-jet cutting, press braking, machining, casting, forging, extrusion, additive manufacturing, or any combination. Joints may be welded (MIG, TIG, spot), brazed, bonded, or mechanicallyAtty Ref. No.: 2025-846-01359-JBLfastened with threaded or non-threaded hardware. Tolerances may be selected to achieve repeatable alignment in field conditions.

[0069] Operating environment. Systems may be used in temperatures from about -40°C to about 85°C, under dust, moisture, salt-spray, and UV exposure. Drainage apertures, sealed connectors, and UV-stable polymers may be employed for longevity.

[0070] The modular hitch rack system of the present disclosure is configured to be used with a variety of vehicles, including but not limited to pickup trucks, SUVs, sedans, and coupes. Any vehicle equipped with a trailer hitch may use the modular hitch rack system of the present disclosure.

[0071] In some embodiments the bay is defined by brackets, flanges, posts, or a perimeter frame that receives the module without requiring sliding motion along guide rails. For example, a module may be lowered vertically into the bay, pivoted into the bay on a hinge, or offered up in a straight-line approach from the rear or side, and then drawn into a seated position by the quick-release latch. The bay geometry and locating interface cooperate to constrain at least pitch and yaw at the seated position regardless of whether the module is slid along rails or placed directly into the bay.

[0072] The locating interface may be positioned so that it engages primarily at or near the seated position. Thus, even when a module is placed into the bay without sliding along rails, the locating interface still provides repeatable constraint of pitch and yaw once the quickrelease latch draws the module into contact with the rack frame.

[0073] In certain embodiments, the quick-release latch not only retains the module in the seated position but also generates a seating motion that pulls the module into firm engagement with the locating interface and backplane. For example, an over-center cam can convert a small handle motion into both axial draw-in and clamping, allowing a user to loosely place the module in the bay and then actuate the latch to complete alignment and electrical mating.

[0074] The modular hitch rack system of the present disclosure is configured to engage with a vehicle’s trailer hitch receiver. In some embodiments, the modular hitch rack system may directly engage with the vehicle’s trailer hitch receiver or an adapter may be used. The adapter may change the receiver size in order to engage the modular hitch rack system.

[0075] The modular hitch rack system is configured for ease of use for a plurality of activities. The modular hitch rack system is configured to allow one or more storage racks of the modular hitch rack system (or other components, such as, but not limited to, a BBQ) toAtty Ref. No.: 2025-846-01359-JBLrotate or swing from a stowed position to an open position. The open position allows a user to access the rear of the vehicle. The rear of the vehicle may include a variety of access points. These access points may include a tailgate, one or more cargo doors, a cargo hatch, and / or a spare tire (whether mounted on the rear or bottom (underneath) of the vehicle). In some applications, such as for use with typically older vehicles with rear-access fueling, the modular hitch rack system may allow the user to swing the modular hitch rack system to the open position to allow access to the rear-mounted fueling port of the vehicle. The modular hitch rack system as configured allows a user to access the rear portion of the vehicle without the need to unload the modular hitch rack system.

[0076] A variety of components may be used with the modular hitch rack system. It should be understood that the embodiments described herein are exemplary and not limiting.

[0077] One component of the modular hitch rack system that may be used is the storage rack component. The storage rack component may be configured in a plurality of sizes to receive various shaped cargo. In some embodiments, the storage rack may be configured with a solid floor and solid sides in the form of a bin or container. In this embodiment, the solid floor and solid sides of the storage rack container retain a plurality of loose components and / or liquids that may be present with the cargo. This configuration may be useful when the user wishes to retain all of the loaded cargo and / or prevent the cargo from exiting the container. For example, and without limitation, the cargo may be firewood. It is anticipated that the container may include a locking (or latching) cover or lid to completely enclose the container storage rack. In other embodiments, the storage rack component may be configured with a plurality of slats such that air may pass through the storage rack component. This may be beneficial for several reasons. Firstly, the items carried in the storage rack may leak, so the openings between the slats may allow for liquid to drip through unto the ground. Secondly, the slats may save weight when compared to a solid wall storage rack component. Finally, the slats may provide additional strength to carry heavy cargo, such as a fully loaded cooler or ice chest.

[0078] Another component of the modular hitch rack system that may be used is a grilling station (or BBQ). The grilling station component may include a BBQ grill that may use charcoal, wood, propane, or another fuel source to produce heat. The grilling station may include a table portion for storing food or other supplies to be used while using the grilling station component of the modular hitch rack system. The grilling station component may include a lid that may be securable (via a lock or latch, for example) to prevent the lidAtty Ref. No.: 2025-846-01359-JBLopening while the vehicle carrying the modular hitch rack system including the grilling station component is in motion or is parked, to prevent theft or vandalism. The grilling component may include a table or workspace as well as one or more cupholders, in certain embodiments.

[0079] Another component of the modular hitch rack system that may be used is a food prep station / table. The food prep station / table may be used in conjunction with the grilling station component of the modular hitch rack system or separately. For example, the modular hitch rack system in one embodiment may include a grilling station component and a food prep station component.

[0080] In this configuration, a user may use the food prep station component to store food to be cooked on the grilling station component as well as to store food already cooked using the grilling station component. Alternatively, the food prep station component may be used to serve food or other food-related items, or as a place to keep belongings off of the ground. By having the grilling station component and the food prep station component, in one embodiment, on opposite sides of the modular hitch rack system (and also on opposite sides of the vehicle trailer hitch), a user may be able to access the interior of the vehicle equipped with the modular hitch rack system of the present disclosure. This is advantageous as it allows the user to retrieve items from the vehicle without having to remove or move the grilling station component or the food prep station component as each may be rotated or moved clear of the vehicle. Once those two components are clear of the vehicle, the user may open the hatch, tailgate, cargo door, trunk or other portion of the vehicle to access cargo, or allow the user or others to enter or exit the vehicle.

[0081] In another configuration, the food prep station component may be located under the grilling station component of the modular hitch rack system. In this configuration, the food prep station component is located conveniently close to the grilling station component to allow a user to quickly and easily move food to be cooked on the grilling station component or to remove cooked food from the grilling station component to the food prep station component. Additionally, items related to the cooking of food (seasoning, sauces, cooking tools, etc.) may also be conveniently located on or about the food prep station component as well as the grilling station component. For example, and without limitation, it is contemplated that one or both of the grilling station component and the food prep station component may include provisions for storing food-related items (tools, condiments, towels, etc.).Atty Ref. No.: 2025-846-01359-JBL

[0082] Another component of the modular hitch rack system is the bike rack component. The bike rack component may attach (like the other components of the modular hitch rack system) to the modular hitch rack system and allow the bike rack to move, pivot, or otherwise rotate out of the way of the vehicle equipped with the modular hitch rack system. The bike rack may be configured to carry one or more bicycles of the same or differing sizes. By using the term “bicycle” or “bike” it is intended to represent a plurality of one- or two-wheeled vehicles at the minimum, including traditional pedal bikes, electronic or “e-bikes,” scooters, and other related transport vehicles. One or more bikes may be secured to the bike rack component using included storage and securing devices and / or use supplemental devices (padlock, chain, etc.). As the bike rack component (and the other components described herein) of the modular hitch rack system may be securedly attached to the modular hitch rack system, additional security devices of the bike rack components and other components of the modular hitch rack system may be included and / or contemplated. The bike rack component allows the user to move the bike rack (with or without one or more bikes) from a stowed position adjacent to the vehicle to an open or partially open position away from the vehicle to access the cargo area located at the rear of the vehicle, adjacent to the trailer hitch.

[0083] Another component of the modular hitch rack system is the wild game processing component. The wild game processing component may be configured to allow a user (hunter) to process wild game after a hunt.

The TV / video component may be configured to hold a TV display or a movie screen, or both. The TV / video component may be moved through the range of motion of the components of the modular hitch rack system, which include adjacent to the vehicle trailer hitch, to a plurality of positions about the rotation axis of the trailer hitch and / or the modular hitch rack system. In this way, users may deploy the TV / video component of the modular hitch rack system and then move the TV / video component to a position that is most suitable to the particular location. Users may then play a video or a video game on the TV / video display or movie screen. The TV / video component may include power connections to operate the video devices. The power connections may include, as described herein, onboard power of the modular hitch rack system, the vehicle equipped with the modular hitch rack system, or an external power supply.

[0089] The modular hitch rack system is configurable with adjustable height for multiple components. For example, two storage rack components may be deployed on the modular hitch rack system such that the first storage rack component is located above the second storage rack component. In another example, a grilling component may be deployed above aAtty Ref. No.: 2025-846-01359-JBLstorage rack component or above a food prep station component. This configuration, among others contemplated by this disclosure, enables maximum use of the available space provided by the modular hitch rack system.

[0090] Each component of the modular hitch rack system may be configured to attach to the base structure of the modular hitch rack system. The base structure of the modular hitch rack system is the portion that directly engages the vehicle trailer hitch. When so attached, the components may be moved independently or in unison, depending on the configuration of each component and / or whether or not the components are physically connected. The movement of each component may be through at least a wide arc centered upon the base structure, but other compound movements are contemplated whereby additional movements are possible.

[0091] The modular hitch rack system may be configured with a latching mechanism or device that restrains the modular hitch rack system and its components in a closed position. Similarly, the modular hitch rack system latching mechanism may include restraints to keep the modular hitch rack system and its components in a variety of open positions - from full open to a range of positions between fully open and closed. In this way, the modular hitch rack system and its components may be prevented from unintended movement through user interaction, or by other forces, such as the wind or gravity.

[0092] It should be noted that the components of the modular hitch rack system may be locked in the stored position for transportation while mounted to the vehicle via its trailer hitch. Locking may be accomplished by a mechanical device, and may include a keyed lock, a combination lock, or other secure locking device. While some embodiments may be used and removed prior to the movement of the vehicle, it is contemplated that the components of the modular hitch rack system may remain attached (and locked) to the vehicle trailer hitch via the base structure. This configuration allows the user to maximize cargo capacity in the interior of the vehicle while storing the components of the modular hitch rack system (and other items that may be carried in the components) on the exterior of the vehicle via the modular hitch rack system.

[0093] Rack frame and bays. In some embodiments, a rack frame includes opposing guide rails that define a bay sized to receive an interchangeable module. The rails can be linear, dovetail, T-slot, round-rod, or keyed profiles that constrain motion along an insertion axis and cooperate with locating features to constrain pitch, roll, and yaw at a seated position.Atty Ref. No.: 2025-846-01359-JBL

[0094] Locating interface variants. The locating interface may include a tongue-and-receptacle, tapered pin and bore, spherical seat, cam-follower, wedge, or kinematic three-point interface (e.g., vee-groove, flat, cone) to achieve repeatable six-degree-of-freedom constraint. Interfaces may be spring-preloaded, elastomerically isolated, or compliant to absorb tolerance stack-up.

[0095] Quick-release latch options. The quick-release latch may include over-center cams, quarter-turn fasteners, eccentric clamps, lever-actuated toggles, rotary latches, draw latches, or cam-locks to apply a seating force without tools. In some versions an ejection mechanism (e.g., spring, gas strut, or cam-ramp) provides initial extraction force when released.

[0096] Blind-mate interconnects. A backplane at the rear of the bay can provide power and / or data via blind-mate connectors, which can include blade, pogo-pin, leaf-spring, wedge, Anderson-style, multipole circular, or edge-card contacts. To accommodate misalignment, the connector may float translationally and / or angularly on a compliant mount (e.g., grommets, flexures, slots), and may include chamfers or funnels for lead-in.

[0097] Power and data. Power distribution can support low-voltage DC (e.g., 5-60 V) and may include fusing, current limiting, surge protection, reverse-polarity protection, and identification (e.g., resistor ID, EEPROM). Data interfaces can include CAN, LIN, USB, RS-485, Ethernet, or wireless interfaces (e.g., BLE, Wi-Fi) for module identification and telemetry.

[0098] Sensing and safety. A latch sensor may be a limit switch, Hall sensor, inductive sensor, optical interrupter, strain or load cell, or other transducer providing a latched / unlatched state and optional seating force read-out. A safety interlock can inhibit power to the backplane unless the module is seated and latched.

[0099] Thermal and airflow features. Optional airflow shrouds, baffles, or heat-sinks may be provided. Fans may be module-mounted or frame-mounted. Thermal interface materials can couple heat sources to chassis surfaces.

[0100] Non-vehicle implementations. In some embodiments, the rack-frame and module system is implemented in carts, cabinets, workstations, server racks, lab benches, trailers, or building-mounted stations. Vehicle embodiments may be powered by the vehicle system; stationary embodiments may be mains- or battery-powered. This paragraph supports use cases outside a hitch-mounted context.Atty Ref. No.: 2025-846-01359-JBL

[0101] Actuation. Swing motion can be manual or power-assisted using springs, gas struts, torsion bars, dampers, or motorized actuators (e.g., linear actuator, rotary actuator) with limit detection at closed, half-open, and full-open positions.

[0102] Locking and security. Latching may include over-center latches, pawl-and-ratchet, rotary latches, clevis pins with detents, padlock provisions, or keyed cylinders. Travel locks may be redundant, and a lockout feature may prevent deployment on roadways.

[0103] Tray geometry and accessories. Trays may be flat, dished, or contoured with replaceable wear surfaces. The tie-down matrix can include circular, oval, slotted, key-slot, or obround openings arranged in orthogonal and diagonal patterns to support common strap geometries and accessory mounts (e.g., quick-release posts, threaded inserts, T-nuts).

[0104] Structure. Cross members, ribs, and gussets may be formed from tube, channel, angle, hat section, or honeycomb panel. The hinge pin can be removable and captured, and bushings can be metallic, composite, or polymer with optional dust seals.

[0105] Stabilization. A stabilizer can be a single post, dual posts, or an adjustable jack coupled to the swing-arm. In deployed use, the stabilizer post is extended until a groundengaging foot contacts the terrain and carries a share of the payload-induced load. By reacting a portion of the tray load directly into the ground, the stabilizer post reduces bending moments and deflection at the hinge region of the swing-arm and pivot mast that would otherwise result from the lever arm between the trays and the hitch receiver. The stabilizer may be screw-driven, cam-locked, or spring-biased, and may seat into a ground plate or pad to prevent sinking on soft terrain.

[0106] Lighting and signaling. Optional lighting (e.g., brake / tum / reverse repeaters) and reflectors can improve visibility. Wiring may route through internal channels with weather-sealed connectors and strain relief.

[0107] Retrofit and kit. The platform may be offered as a retrofit kit with brackets, spacers, or adapters for multiple hitch receiver sizes (e.g., 1.25 in, 2.0 in, 2.5 in), and for vehicles with rear-mounted spare tires or swing-doors. Kits may include instructions and hardware assortments for different vehicle geometries.

[0108] Generalized methods. Methods include installing, deploying, loading, securing, servicing, and stowing operations. Steps can be performed in any order, omitted, or repeated as suitable for a given use case. Optional verification steps can include confirming latch engagement (mechanically or via sensor), checking backplane power status, and verifying clearance relative to vehicle doors, tailgates, or obstructions.Atty Ref. No.: 2025-846-01359-JBL

[0109] Control and telemetry. A controller may receive signals from latch sensors, limit switches, load cells, or inertial sensors, and may log deployment state, load estimates, or shock events for maintenance or safety. A mobile device or vehicle interface can display status, alerts, and usage metrics and can gate power distribution to modules.

[0110] As discussed herein, the modular hitch rack system and its plurality of components may be used for a variety of activities. Some or all of these activities may use one or more of the components of the modular hitch rack system described herein or otherwise contemplated. A non-exhaustive list of activities include: sports tailgating, hunting, fishing, camping, construction, sports, outdoor movie viewing, video gaming, etc.[oni] The modular hitch rack system of the present disclosure addresses a common problem to those using their vehicles for various activities. Using traditional hitch storage racks and devices, a user is typically unable to open a tailgate or cargo hatch / door without removing the traditional hitch storage rack. This is often difficult to do without unloading the cargo from the traditional rack first, then removing the cargo. Once the user has accessed the vehicle, the process must be reversed. This process wastes time and energy.

[0112] The modular hitch rack system of the present disclosure includes, in addition to the components and base structure as previously described, a hinge structure. As discussed, the hinge structure may be incorporated as a separate component, or integrated into the components, or the base structure, or a combination thereof. The hinge structure, regardless of its configuration, enables the components to move relative to the base structure, while remaining securely connected to the base structure. The hinge structure may allow the components to move separately relative to each other, or to move in unison with each other, depending upon the application and configuration of the components. The hinge structure may include a plurality of preset locking positions, such as fully closed, fully open, halfway open, or anywhere in between. The hinge structure may be configured to allow users to reposition the components relative to each other. This repositioning may be advantageous to move the components temporarily (such as to access the cargo area of the vehicle) or more permanently (such as to lower a component to reduce its drag on the vehicle’s aerodynamics.

[0113] The modular hitch rack system is configured to operate with vehicles that include an exterior, rear-facing spare tire, such as the Jeep® Wrangler®, the Ford Bronco®, and the Land Rover Defender®. As these vehicles include a side-swinging door, the modular hitch rack system of the present disclosure is configurable to operate with these types of vehicles.Atty Ref. No.: 2025-846-01359-JBL

[0114] In some embodiments, the latch sensor comprises a Hall-effect sensor, inductive proximity sensor, optical interrupter, or limit switch positioned to indicate a latched state.

[0115] In some embodiments, the blind-mate backplane connector includes a floating mount that permits at least ±1.5 mm translational compliance and at least ±2 degrees angular compliance.

[0116] In some embodiments, the swing-arm includes a gas-spring or damper configured to control opening speed and reduce impact at end-stops.

[0117] In some embodiments, the tie-down matrix includes at least two-hole geometries selected from circular, slotted, and key-slot to facilitate orthogonal and diagonal strap routing.

[0118] In some embodiments, the stabilizer post includes a foot with a high-friction pad and a telescoping section with detents or a threaded jack.

[0119] In some embodiments, modules communicate identity and capability information to the rack via a wired or wireless interface to enable power budgeting and interlocks.

[0120] In some embodiments, trays are removable from the swing-arm via captive fasteners or quick-release pins to facilitate service, reconfiguration, or storage.

[0127] Overview and Terminology

[0128] As used herein, MS2 Racked and modular hitch rack refer to the same inventive platform. References to front, rear, left, and right are from the perspective of an observer standing behind the vehicle.

[0129] Referring generally to the drawings, an illustrative embodiment of the modular hitch rack 100 includes an upper rack / carrier 102 supported by an upper carrier arm 103. Lower rack / carrier 104 is disposed (in some configurations) below upper rack (or tray) 102. Upper carrier stabilizer / support leg 106 is connected to upper rack 102 and / or upper carrier arm 103 on one end and the opposite end of upper carrier stabilizer 106 is connected to main frame 110. Main frame 110 supports lower rack 104 and hitch mount 108. Upper rack 102 and lower rack 104 may include a deck surface 107. In some embodiments, the support arm / upper carrier stabilizer 106 and main frame 110 functions as a pivot mast coupled to the vehicle V via the hitch mount 108, which is configured as a receiver insert for a hitch receiver of the vehicle V. Upper carrier stabilizer 106, together with any attached cross members and trays / racks 102, 104, functions as a swing-arm pivoting about hinge 114 relative to the main frame 110. Hitch mount 108 may be configured as a receiver insert sized to be received in a standard hitch receiver (e.g., 1.25 in, 2.0 in, or 2.5 in square tube) and secured with a hitch pin and clip.

[0130] Upper rack 102 and lower rack 104 may include guardrails 112 disposed, for example, about the perimeter of upper rack 102 and / or lower rack 104. Main frame 110 also includes one or more hinge / pivots 114. Hinge 114 is connected to upper carrier stabilizer 106 and allows it (and upper rack 102) to rotate about hinge 114. In operation, hinge 114 includes one or more locking pins 121 to prevent rotation of hinge 114. Upon activation of pin 121, hinge 114 allows upper rack 102 to rotate from a first (stowed) position behind tailgate T of vehicle V to a plurality of positions in an arc centered on hinge 114.Atty Ref. No.: 2025-846-01359-JBL

[0131] Upper carrier stabilizer 106 may include a height adjustment device 118. Height adjustment device 118 may include a pin 121 to secure upper rack 102 in a plurality of vertical positions.

[0132] Referring now to Figures 3 and 4 and other Figures herein, upper rack 102 may be rotated from a stowed position in proximity to tailgate T to a position approximately 90 degrees from tailgate T. Similarly, lower rack 104 may also be rotated from a stowed position in proximity to tailgate T to a position also 90 degrees from tailgate T - thereby exposing the tailgate T of vehicle V. In these positions, a user may access vehicle V via the open tailgate T (or in the case of other vehicles without a tailgate, a truck, cargo area, etc.). Figure 4 illustrates a further rotational deployment of upper rack 102 and lower rack 104, 180 degrees from the original stowed position behind tailgate T.

[0133] Referring generally to the Figures, in some embodiments grill G replaces upper rack 102 in modular hitch rack 100. Grill G may also include cupholders 120 and cutting board 122. Similar in operation to upper rack 102, grill G may be rotated from a stowed position behind tailgate T to positions including, but not limited to, 90 or 180 degrees from the stowed position.

[0134] In other embodiments, lower rack 104 may include an internal platform 124 and an external platform 126. In this configuration, lower rack 104 may be utilized, for example, as a seat by rotating external platform 126 via a pair of platform hinges 128. In operation, for example, the seat formed by lower rack 104 equipped with internal platform 124 and / or external platform 126 may provide a seating surface for one or more users. Similarly, as described above, lower rack 104 so equipped may be rotated from the stowed position to other positions as desired.

[0135] Referring now to Figures 19 and 20, upper rack 102 may be replaced by a hoist arm 130 and hoist attachment 132. Hoist 134 is attached to hoist arm 130 and includes hoist hook 136. Hoist arm 130, hoist attachment 132, hoist 134 with hook 136 may be rotated via hinge 114 mounted to main frame 110. For example, and without limitation, hoist 134 may be used to load or unload cargo from vehicle V. In other embodiments, hoist 134 and hook 136 may be used to lift and hold a hunted deer, then optionally loaded it in vehicle V.

[0136] In other embodiments, lower rack 104 (or upper rack 102) may be supplemented by adding TV / screen stand 140 with TV / stand mount 142 (see Figs. 21-22, etc.). TV / stand mount 142 is configured to secure a TV screen or a movie screen. In operation, rotating lower rack 104 equipped with TV / screen stand 140 allows a user to position the TV or screen in aAtty Ref. No.: 2025-846-01359-JBLdesired position within the rotational arc using hinge 114. Stand 142 may be stowed alongside lower rack 104 (or upper rack 102) when not in use (see Fig. 24.).

[0137] In some vehicle-mounted implementations, the bay corresponds to an accessory region on a hitch rack platform, and the modules include accessory units such as storage racks, grills, hoists, or work surfaces that are received in the bay and secured at a seated position by quick-release latch hardware without requiring the modules to slide along guide rails.

[0138] Figure 25 illustrates another embodiment of the present invention. On the left side of the vehicle V, the modular grill G is installed on the modular hitch rack 100 via upper carrier stabilizer 106 and is rotatable via hinge 114 secured to main frame 110, which is in turn secured to vehicle V via hitch mount 108. On the opposite side of hitch rack 100, lower rack 104 is also secured to main frame 110, but via a second hinge 114. Stowed within lower rack 104 is cooler 150. Also attached to lower rack 104 is TV stand 140 and TV mount 142 that is securely holding TV 144.

[0139] Figure 26 illustrates yet another configuration of the modular hitch rack 100. In this configuration, grill G is located on the left, supported by upper carrier stabilizer 106 and rotationally movable via hinge 114 connected to main frame 110. Beneath grill G is lower rack 104 containing cooler 150 and also including a stowed TV stand 140.

[0140] Figures 27 - 29 illustrate another embodiment of the modular hitch rack 100. In addition to the configuration shown in Fig. 26, a bike rack 160 is added to grill G (or upper rack 102, in other embodiments). Bikes B may be stowed on the bike rack 160 and using the hinge 114, grill G and bike rack 160 may be rotated about hinge 114 to allow access to grill G, vehicle V, etc.

[0141] Figures 30-31 illustrate another embodiment of the hitch rack 100 of the present disclosure. In this embodiment, mounted to grill G (or upper rack 102 or lower rack 102) is canopy support 172 that mounts canopy 170. Depending on the positioning of canopy 170 and canopy support 172 (as well as grill G, in this embodiment), canopy 170 may be positioned to provide shelter underneath an area in proximity to the hitch rack 100.

[0142] Figures 32-33 illustrate another embodiment of the hitch rack 100. In this embodiment, upper rack 102 is supplemented with work surface 180. It is anticipated that work surface 180 may be configured in a separate module apart from upper rack 102 (or lower rack 104). Work surface 180 may include one or more tool holders 182, a vice 184 and a measuring guide 186. Work surface 180 allows the hitch rack 100 to be used as a portableAtty Ref. No.: 2025-846-01359-JBLwork location, such as for a carpenter or homeowner, whereby supplies stored in connected vehicle V may be easily accessed (especially via tailgate T, for example).

[0143] Figure 34 illustrates another embodiment, grill G with lower rack 104 and cargo tray 190. Cargo tray 190 may be used to transport or store cargo of various shapes and sizes. Cargo tray 190 is mounted to cargo tray arms 192, which are connected to main frame 110 and / or lower rack 104.

[0144] Figures 35 - 38 illustrate another embodiment of hitch rack 100. Grill G is shown in the upper location and beneath grill G is storage box 194 in the lower location (in the position of lower rack 104 in other embodiments). Storage box 194 also includes storage box handle 196.

[0145] Figures 39 - 42 illustrate various configurations of hitch rack 100. In one embodiment shown in Figs. 39 - 40, lower rack 104 is on the left, while grill G is shown on the right. The position of the modules is determined by user preference and is limited only by the user’s imagination or needs at the time of use. Figures 41 -42 illustrate another configuration, with lower rack 104 on the left and upper rack 102 on the right. In this embodiment, a support arm 105 is added to upper rack 102 to provide additional weight capacity to upper rack 102.Similarly, as shown herein, a support arm 105 may be added to lower rack 104 (and other modules).

[0146] Figures 43 - 44 illustrate another embodiment of the hitch rack 100. Grill G is shown mounted on the left, and lower rack 104 is shown (with cooler 150) mounted on the right. For increased capacity, main frame 110 extends under lower rack 104.

[0147] Figures 45 - 46 illustrate the higher capacity embodiment of hitch rack 100 shown in Figs. 43 - 44, but with upper rack 102 substituted for grill G. In this embodiment, both upper rack 102 and lower rack 104 include cupholders 120. Figures 47 - 62 illustrate different views of the same embodiment; however, in Fig. 52 for example, support leg 105 is shown giving additional weight capacity to both upper rack 102 and lower rack 104.

[0148] Figures 63 - 66, 69, 74 illustrate components of the hitch rack 100 of the present disclosure. Lower rack 104 is shown secured to support leg 105 and upper carrier stabilizer 106, and hinge 114, all of which in turn are mounted to main frame 110. Pins 121 allow for the selectable movement (e.g., rotation) of those components when activated by the user. Height adjustment device 118 may be positioned by the user to raise or lower upper rack 102, for example. Figures 67 - 68, 70 - 73, and 75 - 79 illustrate additional configurations of the modules of the hitch rack 100.Atty Ref. No.: 2025-846-01359-JBL

[0149] Swing-arm Cargo Platform Embodiment

[0150] In embodiments, upper rack 102 and upper stabilizer 106 are coupled to main frame 110 and hinge 114. Hinge 114 allows a user to swing upper rack 102 and upper stabilizer 106 from a closed position adjacent to tailgate T of vehicle V (for example) to one or more deployed positions. Stops included in hinge 114 and selectively secured by pin 121 lock the upper rack 102 and upper stabilizer 106 in a desired position. Returning the configuration to the original state is the reverse process. The pin(s) 121 are configured to secure upper rack 102, upper stabilizer 106 (as well as other modular components described herein) for travel, storage, parking, etc.

[0151] Trays, Perimeter Guards, and Tie-down Matrix

[0152] Each upper rack 102 and lower rack 104 forms a tray that includes a perforated deck 107 bordered by side rails 112 forming a perimeter guard. The perforated deck 107 presents a tie-down matrix with holes and / or slots to receive straps or modular brackets in some embodiments. The matrix enables orthogonal and diagonal strap vectors to restrain shifting payloads such as coolers 150 and / or totes 194.

[0153] Structure and Fastening

[0154] Cross members and gussets couple the racks 102, 104 to the swing-arm 106 and resist torsion with cargo applied. Fasteners can include carriage bolts through countersunk perforations of the deck 107 with nuts and washers accessible from the underside. The hinge 114 can incorporate a removable hinge pin 121 for service or arm replacement.

[0155] Stabilizer Post and Field Use

[0156] A support leg 105 is optionally extendable to contact the ground when the swing-arm 106 is deployed. In some embodiments, the support leg 105 functions as a stabilizer post that telescopes between a stowed length and an extended length and includes a locking collar, detent, or jack mechanism to hold the leg at a selected height. A ground-engaging foot on the stabilizer post can include a high-friction pad or enlarged surface to resist sliding and to distribute load on pavement, soil, or other terrain.

[0157] When deployed under the swing-arm 106, the stabilizer post supports at least a portion of the combined weight of trays 102, 104 and their payloads, such as a cooler payload 150 and a tote payload 194. This load sharing reduces the bending moment and vertical deflection at hinge 114 and at the hitch-mounted pivot mast 110 that would otherwise occur due to the lever arm between the trays and the vehicle hitch. In some embodiments, the stabilizer post incorporates a jack screw, cam jack, or ratcheting jack that applies a slightAtty Ref. No.: 2025-846-01359-JBLupward pre-load into the swing-arm 106 so that the trays remain substantially level under load and the assembly achieves a higher practical payload capacity than comparable swing-away racks that do not employ a ground-contacting stabilizer.

[0158] Method of Deployment and Loading

[0159] In one embodiment the method is as follows: (i) unlatch the locking pin 121; (ii) rotate the upper rack 102, lower rack 104, grill G, etc. to a selected deployed position where a position stop to receive pin 121 provides retention; (iii) if provided, extend the support leg 105 to the ground; (iv) place the payload on one or both racks 102, 104; (v) route straps through the decks 107 of racks 102, 104 to secure the payload; and (vi) retract support leg 105 (optionally deployed), rotate the racks 102, 104 to the closed position, and re-engage the pin 121 for travel. In some methods, the user extends and locks the stabilizer post to the ground before loading heavier payloads so that the stabilizer carries a portion of the load during both deployment and travel.

[0160] Compatibility and Modularity

[0161] The hitch rack 100 accepts interchangeable accessory modules that mount to the perforated deck 107 using its tie-down matrix, including storage bins 194, cooking surfaces G, winch or crane attachments 130-136, bike mounts 160, and work surfaces 180.Accessories may be installed at either rack 102, 104 to balance loads and to maintain rearvehicle access for a given deployment angle.

[0162] Exemplary Manufacturing and Variations

[0163] Components can be laser-cut and press-braked with weldments at high-stress junctions, or extrusions and castings where appropriate. Surface finishes may include powder coat or anodize. Drainage apertures can be integrated into the perforated deck 107. Variants include detents or cams providing tactile feedback at intermediate angles, integrated reflectors or lighting, lockable latch hardware, and quick-swap hardware for accessories.

[0001] This application claims the benefit of U.S. Provisional Patent Application No.63 / 720,247, filed Nov. 14, 2024, titled “Modular Hitch Rack System,” the entirety of which is incorporated by reference.FIELD OF THE INVENTION

[0002] This disclosure relates to modular rack systems and vehicle-mounted hitch rack platforms for transporting, storing, and supporting equipment and accessories. In various embodiments, a base structure engages a vehicle hitch receiver and supports interchangeable modules that can swing or rotate between stowed and deployed positions to maintain access to the rear of the vehicle while carrying cargo or task-specific components.BACKGROUND

[0003] Racked systems and vehicle-mounted hitch platforms are used to transport, store, and support equipment and accessories in consumer, commercial, and industrial settings.Conventional solutions include fixed cargo carriers, swing-out frames, and task-specific racks. While these products can move payloads, they often introduce practical and serviceability challenges.

[0004] Many existing hitch-mounted platforms obstruct access to rear vehicle areas when loaded, or they provide only a single open position without positive stops for intermediate use. In some cases, latching hardware is not optimized for repeated field use, which can complicate securing the platform for travel. Load retention can also be limited when tie-down patterns are sparse or not aligned with common cargo shapes, making it harder to route straps reliably.

[0005] Similarly, modular rack and bay systems for equipment often depend on tool-based fasteners and loose alignment tolerances that complicate installation and removal. Blind-mate electrical or data connections can be difficult to align repeatably, and cable management addons may increase bulk or interfere with servicing. Vibration transmission and airflow constraints can degrade the performance or longevity of equipment mounted in these racks.1 / 30Atty Ref. No.: 2025-846-01359-JBL

[0006] Therefore, there remains a need for systems that: (i) provide stable, repeatable alignment during insertion and removal, (ii) allow selective movement between closed, intermediate, and fully open positions with positive retention, (iii) support secure load restraint using versatile tie-down matrices or equivalent features, and (iv) facilitate quick, tool-limited servicing while accommodating power and data interfacing where required. Such systems should maintain rear-of-vehicle access, improve safety and usability in the field, and reduce time and effort associated with installation, reconfiguration, and maintenance.SUMMARY OF THE INVENTION

[0007] The following summary is provided to introduce, in a simplified form, selected concepts that are further described in the detailed description below. This summary is not intended to identify all key or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.

[0008] In one aspect, a racked modular system includes a rack frame with opposing guide rails that define a bay, a module sized to slide along the rails, a locating interface that constrains at least pitch and yaw at a seated position, and a quick-release latch arranged to draw the module into the seated position without tools. A backplane at the rear of the bay provides a blind-mate electrical connector aligned to couple with a corresponding connector on the module as the module seats. Optional features include a floating mounting arrangement for the connector to accommodate tolerance variation, vibration isolation between the module and the rails, an airflow shroud, a safety interlock that interrupts power when unlatched, and a latch state sensor for telemetry or control.

[0066] Options and substitutions. Features described in connection with any embodiment may be combined with features of any other embodiment where structurally compatible. Optional features may be omitted unless explicitly required by a given claim. References to examples or embodiments are non-limiting.

[0067] Materials and finishes. Structural members may be formed from steel (e.g., low-alloy, stainless), aluminum alloys, titanium, magnesium, fiber-reinforced composites, engineering polymers (e.g., nylon, acetal, polycarbonate, PBT), or combinations thereof. Surface treatments can include powder coat, paint, anodize, e-coat, plating, passivation, or conversion coatings suited to outdoor and corrosive environments.

[0068] Manufacturing. Components may be made by stamping, laser cutting, water-jet cutting, press braking, machining, casting, forging, extrusion, additive manufacturing, or any combination. Joints may be welded (MIG, TIG, spot), brazed, bonded, or mechanically8 / 30Atty Ref. No.: 2025-846-01359-JBLfastened with threaded or non-threaded hardware. Tolerances may be selected to achieve repeatable alignment in field conditions.

[0069] Operating environment. Systems may be used in temperatures from about -40°C to about 85°C, under dust, moisture, salt-spray, and UV exposure. Drainage apertures, sealed connectors, and UV-stable polymers may be employed for longevity.

[0070] The modular hitch rack system of the present disclosure is configured to be used with a variety of vehicles, including but not limited to pickup trucks, SUVs, sedans, and coupes. Any vehicle equipped with a trailer hitch may use the modular hitch rack system of the present disclosure.

[0071] In some embodiments the bay is defined by brackets, flanges, posts, or a perimeter frame that receives the module without requiring sliding motion along guide rails. For example, a module may be lowered vertically into the bay, pivoted into the bay on a hinge, or offered up in a straight-line approach from the rear or side, and then drawn into a seated position by the quick-release latch. The bay geometry and locating interface cooperate to constrain at least pitch and yaw at the seated position regardless of whether the module is slid along rails or placed directly into the bay.

[0072] The locating interface may be positioned so that it engages primarily at or near the seated position. Thus, even when a module is placed into the bay without sliding along rails, the locating interface still provides repeatable constraint of pitch and yaw once the quickrelease latch draws the module into contact with the rack frame.

[0073] In certain embodiments, the quick-release latch not only retains the module in the seated position but also generates a seating motion that pulls the module into firm engagement with the locating interface and backplane. For example, an over-center cam can convert a small handle motion into both axial draw-in and clamping, allowing a user to loosely place the module in the bay and then actuate the latch to complete alignment and electrical mating.

[0074] The modular hitch rack system of the present disclosure is configured to engage with a vehicle’s trailer hitch receiver. In some embodiments, the modular hitch rack system may directly engage with the vehicle’s trailer hitch receiver or an adapter may be used. The adapter may change the receiver size in order to engage the modular hitch rack system.

[0075] The modular hitch rack system is configured for ease of use for a plurality of activities. The modular hitch rack system is configured to allow one or more storage racks of the modular hitch rack system (or other components, such as, but not limited to, a BBQ) to9 / 30Atty Ref. No.: 2025-846-01359-JBLrotate or swing from a stowed position to an open position. The open position allows a user to access the rear of the vehicle. The rear of the vehicle may include a variety of access points. These access points may include a tailgate, one or more cargo doors, a cargo hatch, and / or a spare tire (whether mounted on the rear or bottom (underneath) of the vehicle). In some applications, such as for use with typically older vehicles with rear-access fueling, the modular hitch rack system may allow the user to swing the modular hitch rack system to the open position to allow access to the rear-mounted fueling port of the vehicle. The modular hitch rack system as configured allows a user to access the rear portion of the vehicle without the need to unload the modular hitch rack system.

[0076] A variety of components may be used with the modular hitch rack system. It should be understood that the embodiments described herein are exemplary and not limiting.

[0077] One component of the modular hitch rack system that may be used is the storage rack component. The storage rack component may be configured in a plurality of sizes to receive various shaped cargo. In some embodiments, the storage rack may be configured with a solid floor and solid sides in the form of a bin or container. In this embodiment, the solid floor and solid sides of the storage rack container retain a plurality of loose components and / or liquids that may be present with the cargo. This configuration may be useful when the user wishes to retain all of the loaded cargo and / or prevent the cargo from exiting the container. For example, and without limitation, the cargo may be firewood. It is anticipated that the container may include a locking (or latching) cover or lid to completely enclose the container storage rack. In other embodiments, the storage rack component may be configured with a plurality of slats such that air may pass through the storage rack component. This may be beneficial for several reasons. Firstly, the items carried in the storage rack may leak, so the openings between the slats may allow for liquid to drip through unto the ground. Secondly, the slats may save weight when compared to a solid wall storage rack component. Finally, the slats may provide additional strength to carry heavy cargo, such as a fully loaded cooler or ice chest.

[0078] Another component of the modular hitch rack system that may be used is a grilling station (or BBQ). The grilling station component may include a BBQ grill that may use charcoal, wood, propane, or another fuel source to produce heat. The grilling station may include a table portion for storing food or other supplies to be used while using the grilling station component of the modular hitch rack system. The grilling station component may include a lid that may be securable (via a lock or latch, for example) to prevent the lid10 / 30Atty Ref. No.: 2025-846-01359-JBLopening while the vehicle carrying the modular hitch rack system including the grilling station component is in motion or is parked, to prevent theft or vandalism. The grilling component may include a table or workspace as well as one or more cupholders, in certain embodiments.

[0079] Another component of the modular hitch rack system that may be used is a food prep station / table. The food prep station / table may be used in conjunction with the grilling station component of the modular hitch rack system or separately. For example, the modular hitch rack system in one embodiment may include a grilling station component and a food prep station component.

[0080] In this configuration, a user may use the food prep station component to store food to be cooked on the grilling station component as well as to store food already cooked using the grilling station component. Alternatively, the food prep station component may be used to serve food or other food-related items, or as a place to keep belongings off of the ground. By having the grilling station component and the food prep station component, in one embodiment, on opposite sides of the modular hitch rack system (and also on opposite sides of the vehicle trailer hitch), a user may be able to access the interior of the vehicle equipped with the modular hitch rack system of the present disclosure. This is advantageous as it allows the user to retrieve items from the vehicle without having to remove or move the grilling station component or the food prep station component as each may be rotated or moved clear of the vehicle. Once those two components are clear of the vehicle, the user may open the hatch, tailgate, cargo door, trunk or other portion of the vehicle to access cargo, or allow the user or others to enter or exit the vehicle.

[0081] In another configuration, the food prep station component may be located under the grilling station component of the modular hitch rack system. In this configuration, the food prep station component is located conveniently close to the grilling station component to allow a user to quickly and easily move food to be cooked on the grilling station component or to remove cooked food from the grilling station component to the food prep station component. Additionally, items related to the cooking of food (seasoning, sauces, cooking tools, etc.) may also be conveniently located on or about the food prep station component as well as the grilling station component. For example, and without limitation, it is contemplated that one or both of the grilling station component and the food prep station component may include provisions for storing food-related items (tools, condiments, towels, etc.).11 / 30Atty Ref. No.: 2025-846-01359-JBL

[0082] Another component of the modular hitch rack system is the bike rack component.

Users may then play a video or a video game on the TV / video display or movie screen. The TV / video component may include power connections to operate the video devices. The power connections may include, as described herein, onboard power of the modular hitch rack system, the vehicle equipped with the modular hitch rack system, or an external power supply.

[0089] The modular hitch rack system is configurable with adjustable height for multiple components. For example, two storage rack components may be deployed on the modular hitch rack system such that the first storage rack component is located above the second storage rack component. In another example, a grilling component may be deployed above a14 / 30Atty Ref. No.: 2025-846-01359-JBLstorage rack component or above a food prep station component. This configuration, among others contemplated by this disclosure, enables maximum use of the available space provided by the modular hitch rack system.

[0090] Each component of the modular hitch rack system may be configured to attach to the base structure of the modular hitch rack system. The base structure of the modular hitch rack system is the portion that directly engages the vehicle trailer hitch. When so attached, the components may be moved independently or in unison, depending on the configuration of each component and / or whether or not the components are physically connected. The movement of each component may be through at least a wide arc centered upon the base structure, but other compound movements are contemplated whereby additional movements are possible.

[0091] The modular hitch rack system may be configured with a latching mechanism or device that restrains the modular hitch rack system and its components in a closed position. Similarly, the modular hitch rack system latching mechanism may include restraints to keep the modular hitch rack system and its components in a variety of open positions - from full open to a range of positions between fully open and closed. In this way, the modular hitch rack system and its components may be prevented from unintended movement through user interaction, or by other forces, such as the wind or gravity.

[0092] It should be noted that the components of the modular hitch rack system may be locked in the stored position for transportation while mounted to the vehicle via its trailer hitch. Locking may be accomplished by a mechanical device, and may include a keyed lock, a combination lock, or other secure locking device. While some embodiments may be used and removed prior to the movement of the vehicle, it is contemplated that the components of the modular hitch rack system may remain attached (and locked) to the vehicle trailer hitch via the base structure. This configuration allows the user to maximize cargo capacity in the interior of the vehicle while storing the components of the modular hitch rack system (and other items that may be carried in the components) on the exterior of the vehicle via the modular hitch rack system.

[0093] Rack frame and bays. In some embodiments, a rack frame includes opposing guide rails that define a bay sized to receive an interchangeable module. The rails can be linear, dovetail, T-slot, round-rod, or keyed profiles that constrain motion along an insertion axis and cooperate with locating features to constrain pitch, roll, and yaw at a seated position.15 / 30Atty Ref. No.: 2025-846-01359-JBL

[0094] Locating interface variants. The locating interface may include a tongue-and-receptacle, tapered pin and bore, spherical seat, cam-follower, wedge, or kinematic three-point interface (e.g., vee-groove, flat, cone) to achieve repeatable six-degree-of-freedom constraint. Interfaces may be spring-preloaded, elastomerically isolated, or compliant to absorb tolerance stack-up.

[0095] Quick-release latch options. The quick-release latch may include over-center cams, quarter-turn fasteners, eccentric clamps, lever-actuated toggles, rotary latches, draw latches, or cam-locks to apply a seating force without tools. In some versions an ejection mechanism (e.g., spring, gas strut, or cam-ramp) provides initial extraction force when released.

[0096] Blind-mate interconnects. A backplane at the rear of the bay can provide power and / or data via blind-mate connectors, which can include blade, pogo-pin, leaf-spring, wedge, Anderson-style, multipole circular, or edge-card contacts. To accommodate misalignment, the connector may float translationally and / or angularly on a compliant mount (e.g., grommets, flexures, slots), and may include chamfers or funnels for lead-in.

[0097] Power and data. Power distribution can support low-voltage DC (e.g., 5-60 V) and may include fusing, current limiting, surge protection, reverse-polarity protection, and identification (e.g., resistor ID, EEPROM). Data interfaces can include CAN, LIN, USB, RS-485, Ethernet, or wireless interfaces (e.g., BLE, Wi-Fi) for module identification and telemetry.

[0098] Sensing and safety. A latch sensor may be a limit switch, Hall sensor, inductive sensor, optical interrupter, strain or load cell, or other transducer providing a latched / unlatched state and optional seating force read-out. A safety interlock can inhibit power to the backplane unless the module is seated and latched.

[0099] Thermal and airflow features. Optional airflow shrouds, baffles, or heat-sinks may be provided. Fans may be module-mounted or frame-mounted. Thermal interface materials can couple heat sources to chassis surfaces.

[0100] Non-vehicle implementations. In some embodiments, the rack-frame and module system is implemented in carts, cabinets, workstations, server racks, lab benches, trailers, or building-mounted stations. Vehicle embodiments may be powered by the vehicle system; stationary embodiments may be mains- or battery-powered. This paragraph supports use cases outside a hitch-mounted context.16 / 30Atty Ref. No.: 2025-846-01359-JBL

[0101] Actuation. Swing motion can be manual or power-assisted using springs, gas struts, torsion bars, dampers, or motorized actuators (e.g., linear actuator, rotary actuator) with limit detection at closed, half-open, and full-open positions.

[0102] Locking and security. Latching may include over-center latches, pawl-and-ratchet, rotary latches, clevis pins with detents, padlock provisions, or keyed cylinders. Travel locks may be redundant, and a lockout feature may prevent deployment on roadways.

[0103] Tray geometry and accessories. Trays may be flat, dished, or contoured with replaceable wear surfaces. The tie-down matrix can include circular, oval, slotted, key-slot, or obround openings arranged in orthogonal and diagonal patterns to support common strap geometries and accessory mounts (e.g., quick-release posts, threaded inserts, T-nuts).

[0104] Structure. Cross members, ribs, and gussets may be formed from tube, channel, angle, hat section, or honeycomb panel. The hinge pin can be removable and captured, and bushings can be metallic, composite, or polymer with optional dust seals.

[0105] Stabilization. A stabilizer can be a single post, dual posts, or an adjustable jack coupled to the swing-arm. In deployed use, the stabilizer post is extended until a groundengaging foot contacts the terrain and carries a share of the payload-induced load. By reacting a portion of the tray load directly into the ground, the stabilizer post reduces bending moments and deflection at the hinge region of the swing-arm and pivot mast that would otherwise result from the lever arm between the trays and the hitch receiver. The stabilizer may be screw-driven, cam-locked, or spring-biased, and may seat into a ground plate or pad to prevent sinking on soft terrain.

[0106] Lighting and signaling. Optional lighting (e.g., brake / tum / reverse repeaters) and reflectors can improve visibility. Wiring may route through internal channels with weather-sealed connectors and strain relief.

[0107] Retrofit and kit. The platform may be offered as a retrofit kit with brackets, spacers, or adapters for multiple hitch receiver sizes (e.g., 1.25 in, 2.0 in, 2.5 in), and for vehicles with rear-mounted spare tires or swing-doors. Kits may include instructions and hardware assortments for different vehicle geometries.

[0108] Generalized methods. Methods include installing, deploying, loading, securing, servicing, and stowing operations. Steps can be performed in any order, omitted, or repeated as suitable for a given use case. Optional verification steps can include confirming latch engagement (mechanically or via sensor), checking backplane power status, and verifying clearance relative to vehicle doors, tailgates, or obstructions.17 / 30Atty Ref. No.: 2025-846-01359-JBL

[0109] Control and telemetry. A controller may receive signals from latch sensors, limit switches, load cells, or inertial sensors, and may log deployment state, load estimates, or shock events for maintenance or safety. A mobile device or vehicle interface can display status, alerts, and usage metrics and can gate power distribution to modules.

[0110] As discussed herein, the modular hitch rack system and its plurality of components may be used for a variety of activities. Some or all of these activities may use one or more of the components of the modular hitch rack system described herein or otherwise contemplated. A non-exhaustive list of activities include: sports tailgating, hunting, fishing, camping, construction, sports, outdoor movie viewing, video gaming, etc.[oni] The modular hitch rack system of the present disclosure addresses a common problem to those using their vehicles for various activities. Using traditional hitch storage racks and devices, a user is typically unable to open a tailgate or cargo hatch / door without removing the traditional hitch storage rack. This is often difficult to do without unloading the cargo from the traditional rack first, then removing the cargo. Once the user has accessed the vehicle, the process must be reversed. This process wastes time and energy.

[0112] The modular hitch rack system of the present disclosure includes, in addition to the components and base structure as previously described, a hinge structure. As discussed, the hinge structure may be incorporated as a separate component, or integrated into the components, or the base structure, or a combination thereof. The hinge structure, regardless of its configuration, enables the components to move relative to the base structure, while remaining securely connected to the base structure. The hinge structure may allow the components to move separately relative to each other, or to move in unison with each other, depending upon the application and configuration of the components. The hinge structure may include a plurality of preset locking positions, such as fully closed, fully open, halfway open, or anywhere in between. The hinge structure may be configured to allow users to reposition the components relative to each other. This repositioning may be advantageous to move the components temporarily (such as to access the cargo area of the vehicle) or more permanently (such as to lower a component to reduce its drag on the vehicle’s aerodynamics.

[0113] The modular hitch rack system is configured to operate with vehicles that include an exterior, rear-facing spare tire, such as the Jeep® Wrangler®, the Ford Bronco®, and the Land Rover Defender®. As these vehicles include a side-swinging door, the modular hitch rack system of the present disclosure is configurable to operate with these types of vehicles.18 / 30Atty Ref. No.: 2025-846-01359-JBL

[0114] In some embodiments, the latch sensor comprises a Hall-effect sensor, inductive proximity sensor, optical interrupter, or limit switch positioned to indicate a latched state.

[0115] In some embodiments, the blind-mate backplane connector includes a floating mount that permits at least ±1.5 mm translational compliance and at least ±2 degrees angular compliance.

[0116] In some embodiments, the swing-arm includes a gas-spring or damper configured to control opening speed and reduce impact at end-stops.

[0117] In some embodiments, the tie-down matrix includes at least two-hole geometries selected from circular, slotted, and key-slot to facilitate orthogonal and diagonal strap routing.

[0118] In some embodiments, the stabilizer post includes a foot with a high-friction pad and a telescoping section with detents or a threaded jack.

[0119] In some embodiments, modules communicate identity and capability information to the rack via a wired or wireless interface to enable power budgeting and interlocks.

[0120] In some embodiments, trays are removable from the swing-arm via captive fasteners or quick-release pins to facilitate service, reconfiguration, or storage.

[0127] Overview and Terminology

[0128] As used herein, MS2 Racked and modular hitch rack refer to the same inventive platform. References to front, rear, left, and right are from the perspective of an observer standing behind the vehicle.

[0129] Referring generally to the drawings, an illustrative embodiment of the modular hitch rack 100 includes an upper rack / carrier 102 supported by an upper carrier arm 103. Lower rack / carrier 104 is disposed (in some configurations) below upper rack (or tray) 102. Upper carrier stabilizer / support leg 106 is connected to upper rack 102 and / or upper carrier arm 103 on one end and the opposite end of upper carrier stabilizer 106 is connected to main frame 110. Main frame 110 supports lower rack 104 and hitch mount 108. Upper rack 102 and lower rack 104 may include a deck surface 107. In some embodiments, the support arm / upper carrier stabilizer 106 and main frame 110 functions as a pivot mast coupled to the vehicle V via the hitch mount 108, which is configured as a receiver insert for a hitch receiver of the vehicle V. Upper carrier stabilizer 106, together with any attached cross members and trays / racks 102, 104, functions as a swing-arm pivoting about hinge 114 relative to the main frame 110. Hitch mount 108 may be configured as a receiver insert sized to be received in a standard hitch receiver (e.g., 1.25 in, 2.0 in, or 2.5 in square tube) and secured with a hitch pin and clip.

[0130] Upper rack 102 and lower rack 104 may include guardrails 112 disposed, for example, about the perimeter of upper rack 102 and / or lower rack 104. Main frame 110 also includes one or more hinge / pivots 114. Hinge 114 is connected to upper carrier stabilizer 106 and allows it (and upper rack 102) to rotate about hinge 114. In operation, hinge 114 includes one or more locking pins 121 to prevent rotation of hinge 114. Upon activation of pin 121, hinge 114 allows upper rack 102 to rotate from a first (stowed) position behind tailgate T of vehicle V to a plurality of positions in an arc centered on hinge 114.20 / 30Atty Ref. No.: 2025-846-01359-JBL

[0131] Upper carrier stabilizer 106 may include a height adjustment device 118. Height adjustment device 118 may include a pin 121 to secure upper rack 102 in a plurality of vertical positions.

[0132] Referring now to Figures 3 and 4 and other Figures herein, upper rack 102 may be rotated from a stowed position in proximity to tailgate T to a position approximately 90 degrees from tailgate T. Similarly, lower rack 104 may also be rotated from a stowed position in proximity to tailgate T to a position also 90 degrees from tailgate T - thereby exposing the tailgate T of vehicle V. In these positions, a user may access vehicle V via the open tailgate T (or in the case of other vehicles without a tailgate, a truck, cargo area, etc.). Figure 4 illustrates a further rotational deployment of upper rack 102 and lower rack 104, 180 degrees from the original stowed position behind tailgate T.

[0133] Referring generally to the Figures, in some embodiments grill G replaces upper rack 102 in modular hitch rack 100. Grill G may also include cupholders 120 and cutting board 122. Similar in operation to upper rack 102, grill G may be rotated from a stowed position behind tailgate T to positions including, but not limited to, 90 or 180 degrees from the stowed position.

[0134] In other embodiments, lower rack 104 may include an internal platform 124 and an external platform 126. In this configuration, lower rack 104 may be utilized, for example, as a seat by rotating external platform 126 via a pair of platform hinges 128. In operation, for example, the seat formed by lower rack 104 equipped with internal platform 124 and / or external platform 126 may provide a seating surface for one or more users. Similarly, as described above, lower rack 104 so equipped may be rotated from the stowed position to other positions as desired.

[0135] Referring now to Figures 19 and 20, upper rack 102 may be replaced by a hoist arm 130 and hoist attachment 132. Hoist 134 is attached to hoist arm 130 and includes hoist hook 136. Hoist arm 130, hoist attachment 132, hoist 134 with hook 136 may be rotated via hinge 114 mounted to main frame 110. For example, and without limitation, hoist 134 may be used to load or unload cargo from vehicle V. In other embodiments, hoist 134 and hook 136 may be used to lift and hold a hunted deer, then optionally loaded it in vehicle V.

[0136] In other embodiments, lower rack 104 (or upper rack 102) may be supplemented by adding TV / screen stand 140 with TV / stand mount 142 (see Figs. 21-22, etc.). TV / stand mount 142 is configured to secure a TV screen or a movie screen. In operation, rotating lower rack 104 equipped with TV / screen stand 140 allows a user to position the TV or screen in a21 / 30Atty Ref. No.: 2025-846-01359-JBLdesired position within the rotational arc using hinge 114. Stand 142 may be stowed alongside lower rack 104 (or upper rack 102) when not in use (see Fig. 24.).

[0137] In some vehicle-mounted implementations, the bay corresponds to an accessory region on a hitch rack platform, and the modules include accessory units such as storage racks, grills, hoists, or work surfaces that are received in the bay and secured at a seated position by quick-release latch hardware without requiring the modules to slide along guide rails.

[0138] Figure 25 illustrates another embodiment of the present invention. On the left side of the vehicle V, the modular grill G is installed on the modular hitch rack 100 via upper carrier stabilizer 106 and is rotatable via hinge 114 secured to main frame 110, which is in turn secured to vehicle V via hitch mount 108. On the opposite side of hitch rack 100, lower rack 104 is also secured to main frame 110, but via a second hinge 114. Stowed within lower rack 104 is cooler 150. Also attached to lower rack 104 is TV stand 140 and TV mount 142 that is securely holding TV 144.

[0139] Figure 26 illustrates yet another configuration of the modular hitch rack 100. In this configuration, grill G is located on the left, supported by upper carrier stabilizer 106 and rotationally movable via hinge 114 connected to main frame 110. Beneath grill G is lower rack 104 containing cooler 150 and also including a stowed TV stand 140.

[0140] Figures 27 - 29 illustrate another embodiment of the modular hitch rack 100. In addition to the configuration shown in Fig. 26, a bike rack 160 is added to grill G (or upper rack 102, in other embodiments). Bikes B may be stowed on the bike rack 160 and using the hinge 114, grill G and bike rack 160 may be rotated about hinge 114 to allow access to grill G, vehicle V, etc.

[0141] Figures 30-31 illustrate another embodiment of the hitch rack 100 of the present disclosure. In this embodiment, mounted to grill G (or upper rack 102 or lower rack 102) is canopy support 172 that mounts canopy 170. Depending on the positioning of canopy 170 and canopy support 172 (as well as grill G, in this embodiment), canopy 170 may be positioned to provide shelter underneath an area in proximity to the hitch rack 100.

[0142] Figures 32-33 illustrate another embodiment of the hitch rack 100. In this embodiment, upper rack 102 is supplemented with work surface 180. It is anticipated that work surface 180 may be configured in a separate module apart from upper rack 102 (or lower rack 104). Work surface 180 may include one or more tool holders 182, a vice 184 and a measuring guide 186. Work surface 180 allows the hitch rack 100 to be used as a portable22 / 30Atty Ref. No.: 2025-846-01359-JBLwork location, such as for a carpenter or homeowner, whereby supplies stored in connected vehicle V may be easily accessed (especially via tailgate T, for example).

[0143] Figure 34 illustrates another embodiment, grill G with lower rack 104 and cargo tray 190. Cargo tray 190 may be used to transport or store cargo of various shapes and sizes. Cargo tray 190 is mounted to cargo tray arms 192, which are connected to main frame 110 and / or lower rack 104.

[0144] Figures 35 - 38 illustrate another embodiment of hitch rack 100. Grill G is shown in the upper location and beneath grill G is storage box 194 in the lower location (in the position of lower rack 104 in other embodiments). Storage box 194 also includes storage box handle 196.

[0145] Figures 39 - 42 illustrate various configurations of hitch rack 100. In one embodiment shown in Figs. 39 - 40, lower rack 104 is on the left, while grill G is shown on the right. The position of the modules is determined by user preference and is limited only by the user’s imagination or needs at the time of use. Figures 41 -42 illustrate another configuration, with lower rack 104 on the left and upper rack 102 on the right. In this embodiment, a support arm 105 is added to upper rack 102 to provide additional weight capacity to upper rack 102.Similarly, as shown herein, a support arm 105 may be added to lower rack 104 (and other modules).

[0146] Figures 43 - 44 illustrate another embodiment of the hitch rack 100. Grill G is shown mounted on the left, and lower rack 104 is shown (with cooler 150) mounted on the right. For increased capacity, main frame 110 extends under lower rack 104.

[0147] Figures 45 - 46 illustrate the higher capacity embodiment of hitch rack 100 shown in Figs. 43 - 44, but with upper rack 102 substituted for grill G. In this embodiment, both upper rack 102 and lower rack 104 include cupholders 120. Figures 47 - 62 illustrate different views of the same embodiment; however, in Fig. 52 for example, support leg 105 is shown giving additional weight capacity to both upper rack 102 and lower rack 104.

[0148] Figures 63 - 66, 69, 74 illustrate components of the hitch rack 100 of the present disclosure. Lower rack 104 is shown secured to support leg 105 and upper carrier stabilizer 106, and hinge 114, all of which in turn are mounted to main frame 110. Pins 121 allow for the selectable movement (e.g., rotation) of those components when activated by the user. Height adjustment device 118 may be positioned by the user to raise or lower upper rack 102, for example. Figures 67 - 68, 70 - 73, and 75 - 79 illustrate additional configurations of the modules of the hitch rack 100.23 / 30Atty Ref. No.: 2025-846-01359-JBL

[0149] Swing-arm Cargo Platform Embodiment

[0150] In embodiments, upper rack 102 and upper stabilizer 106 are coupled to main frame 110 and hinge 114. Hinge 114 allows a user to swing upper rack 102 and upper stabilizer 106 from a closed position adjacent to tailgate T of vehicle V (for example) to one or more deployed positions. Stops included in hinge 114 and selectively secured by pin 121 lock the upper rack 102 and upper stabilizer 106 in a desired position. Returning the configuration to the original state is the reverse process. The pin(s) 121 are configured to secure upper rack 102, upper stabilizer 106 (as well as other modular components described herein) for travel, storage, parking, etc.

[0151] Trays, Perimeter Guards, and Tie-down Matrix

[0152] Each upper rack 102 and lower rack 104 forms a tray that includes a perforated deck 107 bordered by side rails 112 forming a perimeter guard. The perforated deck 107 presents a tie-down matrix with holes and / or slots to receive straps or modular brackets in some embodiments. The matrix enables orthogonal and diagonal strap vectors to restrain shifting payloads such as coolers 150 and / or totes 194.

[0153] Structure and Fastening

[0154] Cross members and gussets couple the racks 102, 104 to the swing-arm 106 and resist torsion with cargo applied. Fasteners can include carriage bolts through countersunk perforations of the deck 107 with nuts and washers accessible from the underside. The hinge 114 can incorporate a removable hinge pin 121 for service or arm replacement.

[0155] Stabilizer Post and Field Use

[0156] A support leg 105 is optionally extendable to contact the ground when the swing-arm 106 is deployed. In some embodiments, the support leg 105 functions as a stabilizer post that telescopes between a stowed length and an extended length and includes a locking collar, detent, or jack mechanism to hold the leg at a selected height. A ground-engaging foot on the stabilizer post can include a high-friction pad or enlarged surface to resist sliding and to distribute load on pavement, soil, or other terrain.

[0157] When deployed under the swing-arm 106, the stabilizer post supports at least a portion of the combined weight of trays 102, 104 and their payloads, such as a cooler payload 150 and a tote payload 194. This load sharing reduces the bending moment and vertical deflection at hinge 114 and at the hitch-mounted pivot mast 110 that would otherwise occur due to the lever arm between the trays and the vehicle hitch. In some embodiments, the stabilizer post incorporates a jack screw, cam jack, or ratcheting jack that applies a slight24 / 30Atty Ref. No.: 2025-846-01359-JBLupward pre-load into the swing-arm 106 so that the trays remain substantially level under load and the assembly achieves a higher practical payload capacity than comparable swing-away racks that do not employ a ground-contacting stabilizer.

[0158] Method of Deployment and Loading

[0159] In one embodiment the method is as follows: (i) unlatch the locking pin 121; (ii) rotate the upper rack 102, lower rack 104, grill G, etc. to a selected deployed position where a position stop to receive pin 121 provides retention; (iii) if provided, extend the support leg 105 to the ground; (iv) place the payload on one or both racks 102, 104; (v) route straps through the decks 107 of racks 102, 104 to secure the payload; and (vi) retract support leg 105 (optionally deployed), rotate the racks 102, 104 to the closed position, and re-engage the pin 121 for travel. In some methods, the user extends and locks the stabilizer post to the ground before loading heavier payloads so that the stabilizer carries a portion of the load during both deployment and travel.

[0160] Compatibility and Modularity

[0161] The hitch rack 100 accepts interchangeable accessory modules that mount to the perforated deck 107 using its tie-down matrix, including storage bins 194, cooking surfaces G, winch or crane attachments 130-136, bike mounts 160, and work surfaces 180.Accessories may be installed at either rack 102, 104 to balance loads and to maintain rearvehicle access for a given deployment angle.

[0162] Exemplary Manufacturing and Variations

[0163] Components can be laser-cut and press-braked with weldments at high-stress junctions, or extrusions and castings where appropriate. Surface finishes may include powder coat or anodize. Drainage apertures can be integrated into the perforated deck 107. Variants include detents or cams providing tactile feedback at intermediate angles, integrated reflectors or lighting, lockable latch hardware, and quick-swap hardware for accessories.
