[0001] I'liis application claims the benefit of priority of US Provisional Patent Application Serial No. 63 / 636,240, filed on April 19, 2024, entitled "Vehicle Wash Mitter System,” the entire contents of which is hereby incorporated by reference herein.FIELD

[0002] The present disclosure pertains to the field of vehicle washing systems, specifically to mitter systems.BACKGROUND

[0003] Automotive vehicles are exposed to a variety of environmental contaminants such as dirt, dust, road grime, grease, bird dropping, etc., necessitating frequent cleaning to preserve their aesthetic and functional integrity. Traditional systems for cleaning and treating these vehicles often involve mitter assemblies utilizing arrays of cloth strips or synthetic elements to simulate the action of manual washing. However, there exist significant limitations in current technologies.

[0004] Conventional milter systems are generally designed for a narrow range of vehicle types and sizes, primarily standard passenger vehicles. They frequently lack versatility to accommodate larger or specially modified vehicles like dual-wheeled trucks, sprinter vans, tractor-trailers, and the like. These traditional mitter systems may either fail to make adequate contact with certain areas of a vehicle or they may exert excessive force, potentially causing damage to the vehicle’s exterior. This inadequacy in existing car wash technologies underscores the necessity for innovation. Such challenges not only diminish customer satisfaction, but also impact the operational efficiency of car wash facilities,

[0043] The adjustable mitter assembly will now be described with reference to the accompanying drawings.

[0044] The present disclosure pertains to a height-adjustable car wash mitter system.

[0045] In some embodiments, a mitter system comprises an array of cleaning elements, commonly in the form of cloth strips, synthetic fingers, foam pads, or other pliable materials, designed to engage directly with the surface of vehicles. These elements are positioned to sweep across the vehicle’s exterior, dislodging and removing dirt, grime, and other contaminants through their contact. These systems can deliver a thorough clean without damaging die vehicle’s finish, efficiently mimicking the motion of manual hand washing,

[0046] In some embodiments, as depicted in FIG. I , a miter system 100 can be integrated within a vehicle wash system. As a vehicle moves through the carwash tunnel, mitter elements attached to the mitter system contact the vehicle’s surface. In some embodiments, the mechanical assembly to which these elements are attached can generate a variety of movements aimed at cleaning and removing debris from the vehicles. The interaction between mitter elements and vehicles depends on several factors, including, but not limited to, the vehicle’s size and shape, as well as the relative motion imparted to the mitter elements by the mitter system itself.

[0047] in some embodiments, the mitter system may incorporate a height-adjustment feature. This feature can provide vertical adjustability to the mitter elements, helping to ensure they maintain an optimal distance from the vehicles’ surfaces for efficient cleaning across a variety of vehicle sizes.

[0048] In some embodiments, as depicted in FIG. 2, the mitter system 100 includes a support structure having a pair of vertical shafts 201 and 202, a plurality of mitter baskets 404 that carry cleaning elements (not shown), a hydraulic cylinder 800 for adjusting the height of the mitter system 100, and an actuator mechanism 700 for adjusting the height of and / or rotating the milter system 100. All components are designed for operation in a vehicle wash environment and can be retrofit into existing car wash systems without major modifications,

[0049] In some embodiments, a plurality of trolley wheels 203 interface with the shaft assembly to guide and stabilize the outer shaft 202 as it moves relative to the inner shaft 201 .

[0050] Extending laterally from the shaft assembly is a trolley arm 303, to which at least one frame 301 is affixed. The frame 301 provides a structural platform for supporting various cleaning components, illustrated here by way of example as a miter basket 404, In use, the mi iter basket 404 can hold one or more cleaning elements or cloth assemblies (not shown) that contact a vehicle’s surface.

[0051] In some embodiments, a mounting plate 500 is positioned near the base of the assembly, connecting or supporting the shaft assembly in conjunction with a base plate 600.The base plate 600 may be anchored to the facility floor or other underlying support structure, thereby stabilizing the entire system 100 against dynamic loads generated during vehicle washing operations.

[0052] Also depicted in FIG. 2 is an actuator 700, which may facilitate height adjustment and / or rotational movement of the shaft assembly to accommodate various wash angles or to move the frame 301 and associated cleaning elements out of the vehicle’s path when necessary.

[0053] A hydraulic cylinder / piston 800 is shown coupled between trolley arm 303 and the mounting plate 500, providing controlled vertical motion for raising or lowering the outer shaft 202, and by extension, the milter basket 404 and any installed cleaning elements.

[0054] FIG. 3 illustrates an exploded perspective view of the upper portion of a milter system and provides a more detailed view of various subcomponents that collectively facilitate the cleaning action within the height-adjustable milter system. In this embodiment, the system includes two frames 301 that serve as supporting structures for the cleaning elements, such as one or more mitter baskets 404. A trolley arm 303 extends from the vertical shaft assembly (partially illustrated by the inner shaft 201 and trolley wheels 203), providing a horizontal beam on which the frames 301 and associated components are mounted.

[0055] In some embodiments, a gearbox 401 , driven by a motor 402, together provide mechanical power for actuating various cleaning motions of the mitter baskets 404. In some embodiinents, the gearbox 401 connects to a crankshaft 403, imparting oscillatory or rotational motion to the mitter baskets 404. The mitter baskets 404 may be further coupled to one or more mitter swing bars 407, which allow the mitter baskets 404 to pivot or sway in response to input from the crankshaft 403.

[0056] In operation, the motor 402 and gearbox 401 coordinate the motion of the crankshaft 403, which in turn drives the mitter baskets 404. These baskets may be fitted with cloth strips or other cleaning media (not shown) that contact and clean the vehicle's exterior surfaces. The trolley arm 303 helps position the cleaning assembly within the path of an incoming vehicle, and the vertical support structure (including the inner shaft 201 and outer shaft) can raise or lower the assembly 300 to accommodate vehicles of various heights.

[0057] FIG. 4 presents a side view of the height-adjustable mitter system 100, illustrating the relative positioning of the inner shaft 201 and outer shaft 202, along with the trolley wheels 203 that guide and stabilize the telescoping motion between these two vertical components. Extending from the outer shaft 202 is the trolley atm 303, which supports at least one frame301. Miter baskets 404 are suspended from or otherwise attached to the frame 301 , thereby placing the cleaning elements (not shown) within reach of a vehicle’s exterior.

[0058] A mounting plate 500 is visible near the lower portion of the system, cooperating with the base plate 600 to anchor the entire assembly to the facility floor or similar structural support. The rotary actuator 700, shown at the base region, provides controlled height adjustment and / or rotational movement about the vertical axis defined by the inner shaft 201. Additionally, a hydraulic cylinder / piston 800 is coupled between the outer shaft 202 and the lower support structure, providing vertical movement to the trolley arm 303 and attached components.

[0059] In the embodiment depicted in FIG, 4, the vertical shafts 201 and 202 are positioned on one side of the vehicle path. In some embodiments, vertical shafts 201 and 202 may be positioned on both sides of the vehicle path. In some embodiments, each shaft may be a column that is mounted to the facility floor or an existing framework, such as a mounting plate 500.

[0060] In one embodiment, each shaft is made of a corrosion-resistant metal such as stainless steel or galvanized steel; alternatively, aluminum alloy may be used for a lighter weight structure. The width or diameter and height of the shafts can be selected based on the expected vehicle dimensions and loads. For example, shafts 201 and 202 may each be between3 and 36 inches in diameter and / or width and have a height sufficient to allow a vertical travel range of the miter basket 404 on the order of several feet (eg,, an adjustable range of between4 and 12 feet to accommodate sedans up to tall trucks ).

[0061] In some embodiments, the shaft can provide a vertical extension of at least 72 inches. This measurement is exemplary, and the dimensions can vary beyond 72 inches to suit different design specifications or operational requirements.

[0062] In some embodiments, each vertical shaft 201 , 202 may be supported and guided by trolley wheels 203, bearing assemblies, or equivalent low-friction interfaces at both its upper and lower ends. For instance, the system may comprise both upper and lower sets of trolley wheels 203 to help maintain alignment. These wheels, bearings, or linear bushings ensure smooth sliding or telescoping motion of the shafts during height adjustment, while also stabilizing the shafts against lateral forces. In some embodiments, trolley wheels 203 are disposed between the inner and outer shafts at the top and botom regions of their overlap. This arrangement keeps the movement of the shafts precise and minimizes wobble or binding as the mitter basket 404 is raised and lowered. In some embodiments, the trolley wheels 203 are connected to the outer shaft 202. The wheels, bearings, or guides are preferably made of water-resistant materials (for example, stainless steel or self-lubricating polymer bearings) to endure the wet, debris-laden environment of a car wash,

[0063] In some embodiments, the shafts are rectangular. In some embodiments, the shafts are cylindrical. In some embodiments, the inner shaft 201 has a width or diameter of 24 inches. .In some embodiments, the outer shaft 202 has a width or diameter of 36 inches. In some embodiments, prior to any vertical extension, the inner 201 and outer shafts 202 may have a height of 108 inches. These measurements are exemplary', and the dimensions of the support shaft can vary to suit different design specifications or operational requirements.

[0064] FIG. 5 depicts a front view of the height-adjustable milter system 100, illustrating the relationship between the inner shaft 201 and the outer shaft 202 along their vertical axis. One or more trolley wheels 203 are visible at the interface of these shafts, allowing for smooth, guided movement for height adjustment as the outer shaft 202 slides over the inner shaft 201.Extending oatward from the shaft assembly are two frames 301, which support mitter baskets 404 designed to carry' cleaning elements (not shown).

[0065] A mounting plate 500 is depicted near the base of the assembly, attaching or supporting the vertical shafts in conjunction with a base plate 600, which is typically anchored to the facility' floor. The base plate 600 thus helps stabilize the entire system 100 during operation. A rotary' actuator 700 is shown below the mounting plate 500, facilitating height adjustment and / or rotation of the mitter arm assembly about the central axis defined by the inner shaft 201 .

[0066] FIG. 6 offers a closer view of the mechanical interface between various subassemblies that facilitate the cleaning motion of the mitter system. In this embodiment, frames 301 provide the primary support structure, with brackets and cantilevers to carry and position the cleaning components. Within each frame, a gearbox 401 is driven by a motor 402, which collectively produce the rotational or oscillatory force transmitted through a coupler 405 to a crankshaft 403. The crankshaft 403 in turn actuates one or more mitter baskets 404, causing them to pivot, sway, or otherwise move to engage a vehicle’s exterior surfaces effectively.

[0067] A connecting bracket 406 serves as a structural element to reinforce and align the moving linkages. By integrating the gearbox 401 , motor 402, coupler 405, and crankshaft 403 within a support framework that includes the frame 301, trolley arm 302, and connecting bracket 406, the system provides controlled motion for the cleaning elements attached to the mitter baskets 404.

[0068] FIG. 7 illustrates a partial subassembly of an individual milter basket 404 and its associated linkage components. In this embodiment, a coupler 405 is configured to interface with a driving crankshaft (not shown) via a connecting bracket 406, which mechanically connects the coupler on the crankshaft side to the coupler 405 on the mitter basket 404. The nuter swing bar 407 extends laterally, facilitating pivotal or swaying motion of the mitter basket 404 as it cleans a vehicle’s surface.

[0069] The mitter basket 404 itself features mitter attachment holes 409, positioned to receive fasteners or other securing means for various cleaning media t' e.g., cloth strips or foam elements). By integrating these atachment holes 409 into the basket’s frame, operators can easily replace or adjust cleaning elements to address different vehicle profiles or soil conditions.

[0070] FIG. 8 provides a more detailed perspective of the drive assembly responsible for tiie oscillatory or rotational motion of the mitter baskets. A motor 402 is mechanically coupled to a gearbox 401 , and together they generate the torque needed to drive the crankshaft 403. A coupler 410 is shown interposed between the gearbox 401 and the crankshaft 403, allowing for power transfer while also accommodating slight misalignments that may occur during operation.|0071 ] A mounting bracket 41 I is depicted as a structural support element, seeming the motor 402 and gearbox 401 to the surrounding frame or trolley structure. This bracket 41 1 not only stabilizes the drive assembly under dynamic loads but also simplifies maintenance by allowing for convenient access and removal of the motor 402, gearbox 401, or crankshaft 403 if repairs or replacements become necessary.

[0072] FIG. 9 depicts a top view of a height-adjustable mitter system 100. A trolley arm 303 extends from the vertical shaft assembly and supports at least one frame 301 , which in turn houses multiple mitter baskets 404. A motor 402 and associated drive components (not individually labeled in this figure) are shown mounted adjacent to the frames 301 , where they impart the oscillatory or rotational motion necessary to propel the mitter baskets 4(14 against a vehicle’s surface.

[0073] Also visible in this figure are the trolley wheels 203, which guide and stabilize the outer shaft 202 relative to the inner shaft 201 (not directly labeled here), providing smooth vertical adjustment. A mounting plate 500 is situated near the top of this view, interfacing with a base plate 600 that is anchored to the facility floor or other support structure. Thisarrangement provides both rigidity and stability to the system 100, allowing the mitter arm to be safely raised, lowered, or rotated to accommodate a variety of vehicle profiles.

[0074] FIG. 10 offers a closer, top-down view of the vertical shaft assembly near the base region, highlighting the interaction between the inner shaft 201 , the outer shaft 202, and the trolley wheels 203. The trolley wheels 203 are connected to the outer shaft 202, permitting controlled telescoping motion as the outer shaft 202 is raised or lowered. A mounting plate 500 is shown aligned with the base plate 600, each providing structural support and anchoring points for the shaft assembly. By positioning multiple trolley wheels 203 around the perimeter of the outer shaft 202, the system maintains a stable, centered alignment with the inner shaft 201 , thereby reducing unwanted lateral movement and ensuring reliable performance in the demanding environment of a vehicle wash facility.

[0075] FIG. 1 1 provides a doser look at the vertical shaft assembly and the mechanisms that enable controlled height adjustment in the mitter system. An inner shaft 201 is encased by a telescoping outer shaft 202, with multiple trolley wheels 203 arrayed around the interface. These trolley wheels 203 guide and stabilize the outer shaft 202 as it moves along the inner shaft 201, mitigating lateral play and ensuring smooth vertical travel.

[0076] In some embodiments, the outer shaft 202 is capable of a telescoping motion white supported by the inner shaft 201 , allowing the outer shaft 202 to ascend or descend, thereby raising and lowering the trolley arm 303 arid the attached mitter baskets (not shown in FIG. 11).

[0077] In some embodiments, the mitter system can be further customized through variations in the mitter elements. Different materials, lengths, and configurations of mitter elements can be util ized to optimize the cleaning process for speci fic types of vehicles or dirt accumulation. For example, longer mitter elements may be utilized for vehicles with higher profiles, while shorter, stiffer elements may be beneficial for removing mote significant soil deposits. In some embodiments, the ideal operational distance for the cleaning elements from the vehicle’s surfaces is about 6 inches, which allows lor adequate penetration of the cleaning cloth to engage with the vehicle’s contours.

[0078] In some embodiments, the interplay between the inner 201 and outer shafts 202 is facilitated by wheels 203. These wheels 20.3 can support the weight and rotational forces exerted by the pipes as they move, while minimizing friction and wear between the inner 201 and outer shaft 202. In some embodiments, the wheels 203 are steel.

[0079] In some embodiments, a hydraulic cylinder-piston 800 anchored between the trolley arm 303 and the mounting plate 500 at the base of the assembly, providing die force required to raise or lower the outer shaft 202. By extending or retracting this hydraulic cylinder 800, operators can adjust the height of any attached cleaning elements, such as mitter baskets (not shown in FIG. 1 1 ), to suit varying vehicle dimensions. The mounting plate 500 itself is bolted or otherwise secured to a base plate (not shown here).

[0080] In some embodiments, height adjustment of the mitter basket assembly is accomplished by an actuator. The actuator is configured to raise and lower the hydraulic cylinder 800 and thus the trolley arm 303 and attached components. In the primary embodiment, the actuator is a linear drive mechanism coupled to a hydraulic cylinder 800. When activated, the hydraulic cylinder 800 extends or retracts, thereby translating the trolley arm 303 upward or downward along the shafts 201 and 202.

[0081] In some embodiments, the system comprises a hydraulic height adjustment mechanism. In such configurations, a hydraulic cylinder 800 provides control over the outer shaft’s 202 vertical movement. This system leverages the controlled force of hydraulic fluid moved by pumps, which may be further driven by the pressurized gets.

[0082] In some embodiments, the vertical positioning trolley arm 303 is governed by a pneumatic height-adjustment mechanism. This mechanism employs the high-pressure attributes of a gas, such as nitrogen, to effectuate the alteration of the outer shaft’s 202 height. A pneumatic infrastructure may further include a compressor, an air tank for storage, valves for directional control of the gas, and may be linked to a cyl inder <800 that converts gas pressure into linear motion. The pressurized gas is directed into the cylinder 800, which in turn extends or retracts to adjust the vertical position of the outer shaft 202 and the attached trolley arm 303. This setup allows the mitter elements to maintain a consistent operational distance from the vehicle’s surfaces.|0083| Various types of linear actuators can be utilized to achieve the height adjustment. In one example, a pneumatic cylinder is used: a pressurized air actuator with an internal piston provides the force to lift the basket assembly. A pneumatic system utilizes high-pressure gases and a hydraulic cylinder 800 for vertical movement of the trolly arm 303 via the vertical shafts. In another example, the actuator may be an electric linear actuator, such as a motor-driven screwjack or belt-driven mechanism.

[0084] FIGS. 12-13 provide views of the rotary actuator 700 situated at the base of the mitter assembly, shown in relation to the mounting plate 500 and base plate 600.

[0085] In some embodiments, a base plate 600 anchors the system 100 to the floor of the vehicle wash facility. The base plate 600 may comprise a platform that bears the weight of the entire nutter system 100 and counteracts the operational forces encountered during the cleaning processes. In some embodiments, the base plate 600 is bolted to the floor.

[0086] In an exemplary embodiment, the base plate comprises a thickness of 1 / 2 inch and a width extending 3 inches beyond the width of the outer shaft 202. These measurements are exemplary, and the dimensions can vary to suit different design specifications or operational requirements.

[0087] I 'he rotan' actuator 700 is configured to rotate the vertical shaft assembly (not fully visible in this figure), allowing the entire miner arm to swing or pivot out of a vehicle’s path or to adjust its cleaning angle, A component labeled 701 is attached to or integrated with the rotary actuator 700; in some embodiments, this component 701 may serve as a fluid distribution block or valve manifold, facilitating the controlled flow of hydraulic fluid or other pressurized media within the actuator.

[0088] T 'he mounting plate 500 is shown secured above the rotary actuator 700, providing an interface between the actuator and the rest of the system. Below the actuator, the base plate 600 anchors the assembly to the facility floor or a comparable support structure. By combining the rotational capability of the actuator 700 with the vertical adjustability of the system’s telescoping shafts (not shown in FIGS. 12*13), operators can finely tune the orientation and height of any attached cleaning elements for optimal contact with a wide range of vehicle profiles.

[0089] In some embodiments, the rotation may be actuated by a motor, which may further be equipped with a gear that engages with a corresponding gear on a slewing bearing. The motor exerts rotational force upon the slewing bearing, facilitating control over the rotation of the vertical shafts and the attached trolley arm 303. The system’s configuration is such that it can transfer the motor’s torque to the slewing bearing.

[0090] FIG. 14 presents an exploded perspective of a rotary-actuator subassembly in relation to the mounting plate 500. In the depicted embodiment, a main actuator bousing 702 is shown below the mounting plate, and a component labeled 703 is configured as a coupling or interface ring that fastens to (or aligns with) the mounting plate 500. A separate element, labeled 701 , is attached to or integrated with the actuator housing 702 — in some implementations, this element may serve as a fluid manifold or valve block that regulates the flow of hydraulic fluid or other pressurized media within the actuator.

[0091] When assembled, the ring 703 and the mounting plate 500 provide a secure mechanical connection tor the actuator housing 702, allowing it to rotate or pivot the milter system’s vertical shaft assembly (not shown in FIG. 14). This configuration ensures that both the actuator 702 and its associated fluid-control component 701 can be conveniently installed, serviced, or replaced. By coupling the rotary actuator in this manner, the mitter system retains the ability to adjust its cleaning angles and positions, thereby accommodating a diverse range of vehicle profiles in automated wash environments.

[0092] In some embodiments, the adjustable mitter assembly may be equipped with several safety features to ensure reliable and fail-safe operation. One safety inclusion is a fail-safe locking mechanism for the height actuator. In embodiments where actuator is pneumatic, a failsale pneumatic lock (for example, a pilot-operated check valve) is provided to prevent sudden descent of the basket in the event of air pressure loss. Tins means that if supply pressure is cut off or drops unexpectedly, the lock or check val ve automatically holds the pneumatic cylinder in its current position, keeping the mitter basket from felling onto the vehicle. In electric actuator embodiments, the actuator may incorporate a sell-locking gear mechanism that resists back-driving, or a brake that engages when power is cut, to similarly hold the basket in place and prevent unintended lowering.

[0093] In some embodiments, art emergency stop system is integrated into the controls to halt movement immediately if a hazardous condition is detected or if an operator needs to intervene. Upon activation of an emergency stop, power to the actuator is cut (and valves are closed in pneumatic systems), causing any motion to cease and locking the assembly in its current position via the mechanisms described above. The system may also include mechanical override controls for use in failure scenarios. For example, a manual release valve on a pneumatic or hydraul ic act uator allows an operator to slowly bleed off pressure and lower the basket in a controlled manner if the automated system fails or power is lost. In the case of an electric actuator, a hand crank or override screw interface may be provided to enable manual retraction or extension of the actuator if the motor or controls become non-responsive.

[0094] In some embodiments, the height-adjustable mitter assembly is operated by an automated control system that coordinates its movement with the presence and position of a vehicle in the wash bay. The control system (which may be a programmable logic controller or a dedicated niicrocontroiler-based unit) is configured to adjust the height and angle of the mitter basket dynamically during a wash cycle. Sensors may be utilized to detect the vehicle’s dimensions and position; for example, an overhead ultrasonic or infrared sensor can measurethe height profile of an approaching vehicle, hi some implementations, the system accesses a stored vehicle profile database to automatically select appropriate movement parameters. The database can contain information about common vehicle types or classes - for instance, distinguishing between typical sedans, SUVs, and pickup trucks - and their average heights and roof contours. By identifying the vehicle (e.g.. via an ID input, license plate recognition, or by sensing its height and length profile), the controller can retrieve a pre-programmed profile for that vehicle type and set the initial height of the mitter basket accordingly. For example, if a tall van is identified, the controller keeps the basket at a higher starting position than it would lor a low passenger ear, to avoid any initial contact.

[0095] In some embodiments, manual override capability is also incorporated into the control system. A human operator can at any time take control of the mitter 'height and angle via a control interface, such as a switch console or joystick on the main control panel. This allows the operator to make fine adjustments or respond to unexpected vehicle configurations. For example, if a vehicle has an aftermarket accessory (such as a roof -mounted antenna or rack) or an unusual shape not fully anticipated by the automatic program, the operator might manually raise the basket a few extra inches to ensure safe clearance. The system is designed such that manual input commands will override the automatic control signals, but with built-in limits to prevent unsafe operations (for instance, the control logic can ignore a manual command to lower the basket below a minimum height if a vehicle is detected underneath). After manual intervention, control can be returned to the automatic mode to continue the cycle. [0096 j The control system preferably integrates with the overall vehicle wash control architecture so that the mitter assembly's movement is synchronized with other equipment (such as side brushes, conveyors, and dryers) and timed correctly within the wash cycle. When no vehicle is present, the controller keeps the mitter baskets in a raised, neutral position (often fully up and level, or slightly tilted to let the cleaning strips hang freely) out of the way of incoming vehicles.

[0097] In an alternative embodiment, as depicted in FIG. 15, the miter assembly 100 is secured to the ceiling of a vehicle wash facility rather than anchored to a vertical column or base plate. In this overhead configuration, the frame 301 is suspended from a series of overhead mounting beams or trusses 310, with its comers connected by a set of four springs 900 that extend between the frame 301 and the fixed ceiling structure. The hydraulic cylinders 800 remain tire principal means for extending and retracting the mitter assembly, providingcontrolled vertical travel similar to the primary embodiment, yet the springs 900 introduce an addi tional layer of compliance in the system.

[0098] In some embodiments, the springs 900 serve to absorb and dampen oscillations that might occur as the miter basket 404 moves through its cleaning cycles or interacts with the varying contours of a vehicle. By distributing minor vibrations or shock loads across the spring elements 900, the system 100 can maintain a more stable and balanced frame position, reducing wear and tear on the hydraulic actuators and other structural components. Additionally, the spring tension may help maintain consistent downward contact pressure on the vehicle’s exterior when the hydraulic cylinders 800 are partially extended, thus enhancing the cleaning effectiveness of the suspended mitter baskets 404.|0099| In other embodiments, the springs 900 may facilitate a “float” or “follow” feature, whereby the frame can momentarily yield when encountering an unexpected vehicle protrusion or an unusually high point in the vehicle’s profile. When such a variance occurs, the springs 900 deflect slightly, allowing the cleaning elements to move aside rather than exert excessive force. Once the obstruction passes, the spring bias and hydraulic control return the frame to its nominal operating position. This arrangement thus accommodates incidental variations in vehicle height without requiring real-time control adjustments from the actuator system.

[0100] Although the mounting orientation has shifted from a floor-anchored column to a ceiling-suspended framework, many of the mechanical and control principles remain the same. The hydraulic cylinders 800, for example, continue to provide the primary lifting force for raising or lowering the frame 301 . The control system can be substantially identical to that of the primary embodiment, integrating sensors, emergency stops, and manual overrides. The overall frame construction 301, mi tier baskets 404, crankshaft, and motor-driven gear assemblies remain substantially unchanged from the primary embodiment depicted in FIG. 2. The crankshaft still imparts oscillatory or rotational motion to the mitter baskets, which in turn carry the cleaning elements (e.g., cloth strips or foam fingers). The frame 301 and basket 404 arrangement likewise preserve the modular design, allowing each mitter basket 404 to be easily swapped out, maintained, or retrofitted with different cleaning media. By combining established hydraulic control with strategic spring placement at the four corners, this alternative embodiment provides a ceiling-mounted solution that can reliably handle a broad range of vehicle profiles.

[0101] In some embodiments, the overall framework offered by the mitter arm and support shaft can also be leveraged to integrate additional overhead equipment. This additionalequipment can include a variety of apparatuses, including, but not limited to car wash equipment such as foam generators, rinse bars, heaters and dryers, and other equipment useful in car wash processes. These ancillary components can be attached to the mitter arm, support shaft, and variations of the two. In some embodiments, their attachment and positioning can replace the milter elements. In some embodiments, their attachment and positioning can augment rather titan interfere with the function of the mitter system. Overall, the system provides the ability to adjust the height of a variety ofcleaning elements.

[0102] Example Use Case

[0103] I 'he following example is provided to further describe some of the aspects and embodiments disclosed herein. The examples are intended to illustrate, not to limit, the disclosed aspects or embodiments.|0104] Consider a commercial vehicle wash facility tasked with washing a wide variety of vehicles, including standard passenger cars, sports utility vehicles (SUVs), pickup trucks, sprinter vans, dual -wheeled trucks, and tractor-trailers.

[0105] initially, a compact sedan enters the vehicle wash tunnel. Upon detection by integrated overhead sensors, or through manual initiation by a human operator via a control interface, the mitter system sets its initial operational height using the hydraulic cylinder actuator. The mitter baskets, equipped with cloth or synthetic cleaning elements, are thereby positioned to maintain an optimal cleaning distance from the vehicle’s surface, minimizing potential damage while maximizing cleaning efficiency.

[0106] As the sedan progresses through the wash tunnel, the motor-driven gearbox and crankshaft assembly actuate the mitter baskets in a controlled oscillatory motion. This action removes dirt, grime, and contaminants from the vehicle’s hood, roof, and trunk surfaces, providing thorough coverage without exerting excessive force or pressure.|0107| Subsequently, a larger vehicle, such as a dual-wheeled truck, approaches the wash tunnel. The system either automatically detects and adjusts to the vehicle’s increased height and distinct structural profile through sensor input to the control system, or an operator manually inputs height adjustments via the control interface, hi response, the mitter system's hydraulic actuator extends the outer shaft relative to the inner shaft, guided by trolley wheels, positioning the mitter baskets to accommodate the vehicle’s height. Concurrently, the rotary actuator may be engaged automatically or manually to pivot the milter arm, allowing the cleaning elements to effectively conform around protrusions or specialized equipment (e.g., mirrors, cargo racks) specific to the larger vehicle.

[0108] Throughout the cleaning process, the integrated rotary actuator and heightadjustment mechanism provide additional flexibility. For instance, the rotary actuator allows operators to rotate the entire milter assembly out of the vehicle’s path if an unexpected configuration or obstruction is detected, either automatically by sensors or manually via a control interface,

[0109] In a further operational scenario, a specially modified sprinter van equipped with rooftop accessories enters the wash system. Utilizing the manual override capabilities integrated into the control system, an operator intervenes by adjusting the mitter system’s height slightly above the typical automatic settings, ensuring the safe passage of the vehicle while still cleaning its reachable surfaces.|0110] The mitter system demonstrates operational versatility in handling substantial height, and shape variances. After each wash cycle, the control system resets the mitter system to a neutral raised position, safely clearing the path for subsequent vehicles. The inclusion of' fail-safe features such as pneumatic locks or electric actuator braking ensures safety-, even in the event of a power or pressure loss.
