Description

TECHNICAL FIELD

This application pertains to vehicle washing technology, and more particularly, to a reverse rotation side washer for vehicles.

BACKGROUND

Automatic vehicle wash systems have proliferated in recent years. The convenience and quality of wash afforded by such vehicle wash systems have improved to the point that most kinds of vehicles can be washed using such systems. Nevertheless, conventional vehicle wash systems are deficient in that they often miss cleaning certain areas of the vehicle including portions of the sides and wheels of the vehicle. Conventional vehicle wash systems use non-reverse rotation side washers. Such non-reverse rotation side washers are simple to implement, but fall short in their cleaning efficacy. Running a conventional side washer in a reverse rotation direction is dangerous because the natural behavior of the brushes is to pull themselves into the vehicle and grab, thereby damaging the vehicle.

Conventional cloth attachment cores and hubs are very difficult to maintain when it comes time to replace new cloth. After being exposed in a carwash environment over time, the slots in the cores and hubs expand and weaken. As a result, the cloth material pulls and falls out of the slots, therefore requiring replacement and purchase of a new core or hub every few years. Another problem with conventional cores is it is very difficult to change the cloth material when needed because the cloth becomes very difficult to slide out of the core or hub over time. These are time consuming and expensive tasks.

Accordingly, a need remains for improved methods and systems for providing a reverse rotation side washer for vehicles, and for retrofitting conventional systems. Embodiments of the inventive concept address these and other limitations in the prior art.

FIG. 1A illustrates an example plan-view diagram of a vehicle 105 and a reverse rotation side washer system 100 for the vehicle 105, including a side washer assembly 102 having a stack of horizontal cloth brush panels 140 in accordance with various embodiments of the present inventive concept. FIG. 1B illustrates an example side elevation-view diagram of the side washer assembly 102 without the stack of cloth brush panels 140. FIG. 1C illustrates an example side elevation-view of a shaft assembly 124 of FIG. 1B, and top and bottom views of the shaft assembly 124 of FIG. 1B. Reference is now made to FIGS. 1A, 1B, and 1C.

The vehicle 105 can be an automobile, a passenger vehicle, a self-driving vehicle, a truck, a van, or the like. The vehicle 105 can travel in a particular direction 110, either by its own motive force, or by an external motive force. For example, the vehicle 105 can travel in the direction 110 by way of an automatically guided track system (not shown).

The reverse rotation side washer system 100 can include a side washer assembly 102 disposed on one side thereof. The side washer assembly 102 can include a stack of horizontal cloth brush panels 140 that can be rotated in a reverse direction 145. The term “reverse direction” as used herein refers to a direction of rotation that is with rather than against the direction of travel 110 of the vehicle 105. In other words, in the reverse direction, the side washer assembly is rotated as if it were assisting the vehicle in the direction of travel 110. Put differently, the reverse direction is opposite to the direction of rotation of conventional side washer vehicle washing systems.

The side washer assembly 102 can include a retractable angled primary arm 120 and a retractable secondary arm 130. The retractable angled primary arm 120 can retract out and away from the vehicle 105 as the vehicle 105 makes contact with the stack of cloth brush panels 140. More specifically, the retractable angled primary arm 120 can pivot away from the vehicle 105 by way of pivot 117. The retractable angled primary arm 120 can include an elbow, joint, or rounded oblique bend 122. Moreover, the retractable secondary arm 130 can extend and retract out and away from the angled primary arm 120, and further extend and retract out and away from the vehicle 105, thereby keeping the reverse rotation of the stack of cloth brush panels 140 from applying excessive pressure, tension, and force on the side of the vehicle 105, and preventing the angled primary arm 120 from otherwise being pulled into the vehicle 105.

The retractable angled primary arm 120 and the retractable secondary arm 130 can be joined at pivot 198. The pivot 198 is a retraction point of the cloth brush panels 140, and together with the angled primary arm 120 allows for both the primary arm 120 and the secondary arm 130 to retract away from the vehicle 105 when pressure is applied on the side of the vehicle 105. An upper bracket 190 and a lower bracket 195 (as shown in FIG. 1B) can provide structural support to the pivot 198 or other suitable coupling between the secondary arm 130 and the primary arm 120. Accordingly, the cloth brush panels 140 behave gently and smoothly in reverse rotation. The retractable angled primary arm 120 and the retractable secondary arm 130 work in tandem for a gentle, safe, and effective cleaning of the areas of the sides and wheels of the vehicle 105 that conventional non-reverse rotation side washers miss. In an alternative embodiment, the cloth brush panels 140 can be rotated in a non-reverse rotation direction against the travel direction of the vehicle 105.

The retractable angled primary arm 120 and the retractable secondary arm 130 can be constructed of any suitable rigid material such as metal, steel, aluminum, stainless steel, standard steel, round pipe, box style steel tubing, or the like. The retractable angled primary arm 120 can be coupled to a floor mount 115. In some embodiments, the floor mount 115 can be a freestanding floor mount. A primary shock and spring assembly 125 coupled to the floor mount 115 and the retractable angled primary arm 120 can assist in the retraction of the angled primary arm 120 and prevent the angled primary arm 120 from damaging the vehicle 105. The primary shock and spring assembly 125 can include a tensioner spring. In some embodiments, an inside-mounted secondary shock and spring assembly 136, which can be disposed within the retractable angled primary arm 120, and coupled to the retractable secondary arm 130, can assist in the retraction of the secondary arm 130, to further prevent any damage to the vehicle 105. The secondary shock and spring assembly 136 can include a tensioner spring. Although some figures described and illustrated herein show the internal secondary shock and spring assembly 136, it will be understood that an external secondary shock and spring assembly 135, further described below, can be substituted in each illustrated embodiment for the internal secondary shock and spring assembly 136 without departing from the various embodiments of the inventive concept disclosed herein.

The side washer assembly 102 can include a shaft assembly 124, as shown in FIG. 1B. The shaft assembly 124 can support the stack of cloth brush panels 140. In other words, the stack of cloth brush panels 140 can be secured and rotated by the shaft assembly 124, as further described in detail below. The shaft assembly 124 can include an upright shaft 126 and a cap plate 128 secured to the shaft 126. The cap plate 128 can be secured to the shaft 126 using, for example, two or more screws, pins, or bolts 129. The shaft 126 is preferably about 28 inches long. It will be understood that other suitable shaft lengths include, for example, 21 inches, 28 inches, 35 inches, 42 inches, etc. The shaft 126 can have a three inch diameter or thereabout. The shaft assembly 124 can include a base plate 127. The shaft 126 can be secured to the base plate 127 using two or more screws, pins, or bolts 123, which can be secured to the retractable secondary arm 130 and the motor 187. The motor 187 can cause the shaft 126 to rotate in either the direction 133 or the direction 137.

A cross section 121 taken along line 121-121 of the shaft 126 can be round, square, rectangular, triangular, octagonal, or any suitable shape for stacking the horizontal cloth brush panels 140, which obviate the need for conventional brush cores. The shaft 126 can be used with cloth brush panels 140 in various forms including whole round panels, semicircular half (½) panels, quarter circular (¼) panels, and/or eighth circular (⅛) panels, as further described below. Custom stacking and spacing patterns of the cloth brush panels 140 can be configured so that sides and edges of the cloth brush panels 140 down to even a hundred thousandth of an inch can clean the nooks and crannies of the vehicle 105. The cloth brush panels 140 can be horizontally disposed and stacked, with the shaft 126 running up the middle of the stack. The shaft assembly 124, along with the cloth brush panels 140, can rotate in direction 133 and/or 137. In an alternative embodiment, conventional vertical cloth brush panels can be retrofitted to the shaft 126, as further described in detail below.

As shown in FIG. 1C, the shaft assembly 124 can include the shaft 126, the cap plate 128, screws, pins, or bolts 129 to secure the cap plate 128, and screws, pins, or bolts 123 to secure the shaft 126 to the base plate 127 (of FIG. 1B). A top view 153 of the shaft 126 shows drill holes 143, which can align with and receive the corresponding screws, pins, or bolts 129 to secure the cap plate 128. In some embodiments, a slot can be disposed about one inch below a top surface of the shaft 126 and continue around the shaft 126 to allow for the cap plate 128 to be slid down the shaft 126 and rotated into the slot of the side of the shaft 126 to lock in place, thereby aligning with the drill holes 143. A bottom view 157 of the shaft 126 shows drill holes 147, which can align with and receive the corresponding screws, pins, or bolts 123. The base plate 127 (of FIG. 1B) can include holes that correspond with the drill holes 147 to mount the shaft assembly 124 to the retractable secondary arm 130 and the motor 187. In some embodiments, a central opening 189 can be bored or otherwise formed throughout the entire center of the shaft 126. In some embodiments, the central opening 189 can have a diameter of one and half inches or thereabout. The central opening 189 can reduce the amount of material needed to construct the shaft 126 while maintaining the necessary rigidity and strength of the shaft 126.

FIG. 1D illustrates an example diagram of a vehicle 105 and a reverse rotation side washer system 101 for the vehicle 105 in accordance with various embodiments of the present inventive concept. The vehicle 105 can be an automobile, a passenger vehicle, a self-driving vehicle, a truck, a van, or the like. The vehicle 105 can travel in a particular direction 110, either by its own motive force, or by an external motive force. For example, the vehicle 105 can travel in the direction 110 by way of an automatically guided track system (not shown).

The reverse rotation side washer system 101 can include a first side washer assembly 102 disposed on one side thereof, and a second side washer assembly 104 disposed on the opposite side thereof. The first side washer assembly 102 can include a stack of cloth brush panels 140 that can be rotated in a reverse direction 145. The second side washer assembly 104 can include a stack of horizontal cloth brush panels 140 that can be rotated in a reverse direction 185.

The first side washer assembly 102 can include a retractable angled primary arm 120 and a retractable secondary arm 130. The retractable angled primary arm 120 can retract out and away from the vehicle 105 as the vehicle 105 makes contact with the stack of cloth brush panels 140. The rectractable angled primary arm 120 can include an elbow or joint 122. The retractable secondary arm 130 can further extend and retract out and away from the vehicle 105, thereby keeping the reverse rotation of the stack of cloth brush panels 140 from applying excessive pressure, tension, and force on the side of the vehicle 105. The retractable angled primary arm 120 and the retractable secondary arm 130 work in tandem for a gentle, safe, and effective cleaning of the areas of the sides and wheels of the vehicle 105 that conventional non-reverse rotation side washers miss.

The retractable angled primary arm 120 can be coupled to a floor mount 115. In some embodiments, the floor mount 115 can be a freestanding floor mount. A primary shock and spring assembly 125 coupled to the floor mount 115 and the retractable angled primary arm 120 can assist in the retraction of the angled primary arm 120 and prevent the angled primary arm 120 from damaging the vehicle 105. In one example embodiment, as shown in FIG. 2A, an external secondary shock and spring assembly 135 coupled to the retractable secondary arm 130 can assist in the retraction of the secondary arm 130, to further prevent any damage to the vehicle 105. In an alternative example embodiment, as shown in FIGS. 1A and 2B, an inside-mounted secondary shock and spring assembly 136, which can be disposed within the retractable angled primary arm 120, and coupled to the retractable secondary arm 130, can assist in the retraction of the secondary arm 130, to further prevent any damage to the vehicle 105. Although some figures described and illustrated herein show the external secondary shock and spring assembly 135, it will be understood that the internal secondary shock and spring assembly 136 can be substituted in each illustrated embodiment for the external secondary shock and spring assembly 135 without departing from the various embodiments of the inventive concept disclosed herein.

The first side washer assembly 102 can include a shaft assembly 124. The shaft assembly 124 can support the stack of cloth brush panels 140. In other words, the stack of cloth brush panels 140 can be secured and rotated by the shaft assembly 124, as further described in detail above and below.

The second side washer assembly 104 can include a retractable angled primary arm 160 and a retractable secondary arm 170. The retractable angled primary arm 160 can retract out and away from the vehicle 105 as the vehicle 105 makes contact with the stack of cloth brush panels 140. The rectractable angled primary arm 160 can include an elbow or joint 162. The retractable secondary arm 170 can further extend and retract out and away from the vehicle 105, thereby keeping the reverse rotation of the stack of cloth brush panels 140 from applying excessive pressure, tension, and force on the side of the vehicle 105. The retractable angled primary arm 160 and the retractable secondary arm 170 work in tandem for a gentle, safe, and effective cleaning of the areas of the sides and wheels of the vehicle 105 that conventional non-reverse rotation side washers miss.

The retractable angled primary arm 160 can be coupled to a floor mount 155. A primary shock and spring assembly 165 coupled to the floor mount 155 and the retractable angled primary arm 160 can assist in the retraction of the angled primary arm 160 and prevent the angled primary arm 160 from damaging the vehicle 105. The primary shock and spring assembly 160 can include a tensioner spring. In some embodiments, a secondary shock and spring assembly 175, which can be disposed outside of the retractable angled primary arm 160, and coupled to the retractable secondary arm 170, can assist in the retraction of the secondary arm 170, to further prevent any damage to the vehicle 105. The secondary shock and spring assembly 175 can include a tensioner spring.

The second side washer assembly 104 can include a shaft assembly 164. The shaft assembly 164 can support the stack of cloth brush panels 140. In other words, the stack of cloth brush panels 140 can be secured and rotated by the shaft assembly 164, as further described in detail above and below.

FIG. 2A illustrates an example plan view of a reverse rotation side washer arm assembly 200 of the reverse rotation side washer system 101 of FIG. 1D. FIG. 2B illustrates an example plan view of a reverse rotation side washer arm assembly 201 of the reverse rotation side washer system 101 of FIG. 1D, including an inside-mounted spring and shock assembly 136 in accordance with various embodiments of the present inventive concept. FIG. 3 illustrates an example side elevation view of the reverse rotation side washer arm assembly 200 of the reverse rotation side washer of FIGS. 1, 2A, and 2B. Reference is now made to FIGS. 2A, 2B, and 3.

The reverse rotation side washer arm assembly 200/201 can include a floor mount 115. The retractable angled primary arm 120 can be coupled to the floor mount 115 by a rotational joint or pivot 205 or other suitable coupling. The retractable angled primary arm 120 can be coupled to the secondary arm 130 by a rotational joint or pivot 210 or other suitable coupling. An upper bracket 215 and a lower bracket 220 can provide structural support to the rotational joint or pivot 210 or other suitable coupling between the secondary arm 130 and the primary arm 120.

The reverse rotation side washer arm assembly 200/201 can include a primary shock and spring assembly 125 coupled to the floor mount 115 via connector 235, and to the retractable angled primary arm 120, which can assist in the retraction of the angled primary arm 120. In an example embodiment, as shown in FIG. 2A, the reverse rotation side washer arm assembly 200 can include an external secondary shock and spring assembly 135 coupled to the retractable secondary arm 130 via connector 225, which can assist in the retraction of the secondary arm 130. In an alternative example embodiment, as shown in FIG. 2B, the reverse rotation side washer arm assembly 201 can include an inside-mounted (i.e., internal) secondary shock and spring assembly 136 coupled to the retractable secondary arm 130 via connector 226, which can assist in the retraction of the secondary arm 130. The inside-mounted secondary shock and spring assembly 136 can be disposed within the retractable angled primary arm 120.

The reverse rotation side washer arm assembly 200/201 can include a shaft assembly 124 supported by a shaft and motor base support 230. The shaft assembly 124 and the shaft and motor base support 230 can support the stack of horizontal cloth brush panels 140. In other words, the stack of cloth brush panels 140 can be secured and rotated by the shaft assembly 124 and the shaft and motor base support 230. It will be understood that the reverse rotation side washer arm assembly 200/201 can correspond to the arm assembly of the first side washer assembly 102. Similar features can be present in the second side washer assembly 104. In other words, the first side washer assembly 102 is essentially a mirror of the second side washer assembly 104 and oriented to face each other.

FIG. 4A illustrates an example semicircular (½) cloth brush panel (e.g., 140) in accordance with various embodiments of the present inventive concept. FIG. 4B illustrates an example quarter circular (¼) cloth brush panel (e.g., 140) in accordance with various embodiments of the present inventive concept. FIG. 4C illustrates an example eighth circular (⅛) cloth brush panel (e.g., 140) in accordance with various embodiments of the present inventive concept. Reference is now made to FIGS. 4A, 4B, and 4C.

In some embodiments, the shape of the cloth brush panel can be essentially flat and semicircular (i.e., ½ of a circular piece of material), as shown in FIG. 4A. In some embodiments, the shape of the cloth brush panel can be essentially flat and circular (not shown). The semicircular embodiment, however, allows for less material to be used, and therefore less overall system cost, while achieving the same or better cleaning performance. In still other embodiments, the cloth brush panels can be a quarter circular (¼) “pie section” as shown in FIG. 4B, an eighth circular (⅛) “pie section” as shown in FIG. 4C, and so forth.

Each cloth brush panel (e.g., 140) includes a shaft attachment region 430 having a brush shaft opening 415. The brush shaft opening 415 can be cut to match the contours of the shaft 126. For example, the brush shaft openings 415 can be sculpted or otherwise cut with notches to match and fit to the form of the shaft 126. In other words, the brush shaft openings 415 can be sculpted or otherwise cut with notches to match and fit to the notches and protrusions of the shaft 126. The cloth brush panel (e.g., 140) can each include a partial circular portion 425 encircling at least some of the corresponding brush shaft opening 415. Each cloth brush panel (e.g., 140) can include one or more slot openings 420 through which one or more corresponding elongate stays can be inserted. The elongate stays can have an elongated rectangular shape. The elongate stays can have a length that is similar to that of the shaft 126. Each of the elongate stays can be a flat piece of steel that slides down an entire length of the stack of cloth brush panels (e.g., 140), thereby locking them together and aiding in their simultaneous rotation. The elongate stays are described in further detail below.

The orientation of each cloth brush panel (e.g., 140) can be staggered into many possible configurations and patterns. In other words, as the cloth brush panels (e.g., 140) are stacked on the shaft 126, their orientation can be staggered with respect to each other. Put differently, the cloth brush panels (e.g., 140) can be rotated while being stacked onto variable notches on the shaft 126. The density of the cloth brush panels (e.g., 140) can also be controlled or otherwise made dependent on cloth panel fillers or supports disposed between the cloth brush panels, as also further described below.

Each of the horizontal cloth brush panels (e.g., 140) can be cut to include flat fingers 405. The flat fingers 405 can have a length of seven (7) inches, eight (8) inches, nine (9) inches, or ten (10) inches. The flat fingers 405 can each have a width of ¼ inch, ⅜ inch, or ½ inch. It will be understood that the flat fingers 405 can have other suitable dimensions. A contiguous central region 410 can remain essentially uncut. The contiguous central region 410 can be adjacent to the flat fingers 405 on one side, and the brush shaft opening 415 and slot openings 420 on the other side. Because of the flat orientation of each cloth brush panel, the tips of the flat fingers 405 can achieve a cleaning coverage and density of fractions of an inch, thereby allowing for more vehicle surface cleaning coverage. In some embodiments, the edges of the tips of the flat fingers 405 can achieve a cleaning coverage and density of a hundredth of an inch, a thousandth of an inch, or even as fine as a hundred thousandth of an inch. While the cloth brush panels illustrated in FIGS. 4A, 4B, and 4C show example dimensions, it will be understood that other suitable dimensions can be used without departing from the inventive concepts disclosed herein.

FIG. 5 illustrates an example plan view of a reverse rotation side washer arm assembly 200 including a cloth brush panel 140 of the reverse rotation side washer system 101 of FIG. 1D. The components and associated reference numerals shown in FIG. 5 are described in detail above, and therefore, a detailed description of such components is not repeated.

FIG. 6 illustrates an example plan view of the shaft 126 of FIGS. 1A through 1D. The shaft 126 can include notches 805 and protrusions 810. The notches 805 can be U-shaped. For example, the shaft 126 can have a substantially octagonal cross section with U-shaped notches 805 formed therein along its entire length. The protrusions 810 can each have an angled head drawn to an outwardly facing point. A central opening 189 in the center of the shaft 126 can run the entire length of the shaft 126.

In some embodiments, the shaft 216 is twenty-eight (28) inches in length and three (3) inches in diameter with eight ½ inch notches that continue along the sides of the shaft 126 at twenty-two (22) degrees. The notches 805 can be dual-notches, quad-notches, or the like, with variable degrees. The central opening 189 can be a 1.5 inch hole the extends all the way through the center of the shaft 126. It will be understood that the shaft 126 can have different or other suitable dimensions without departing from the inventive concepts disclosed herein.

FIG. 7 illustrates an example perspective view of stacked cloth brush panels (e.g., 140) of the reverse rotation side washer systems 100/101 of FIGS. 1A through 1D. Some of the components and associated reference numerals shown in FIG. 7 are described in detail above, and therefore, a detailed description of such components is not necessarily repeated.

The horizontal cloth brush panels (e.g., 140) can be stacked on top of each other with the shaft 126 disposed in the center. The density of the cloth brush panels (e.g., 140) can also be controlled or otherwise made dependent on cloth panel fillers 705 or supports disposed between the cloth brush panels (e.g., 140). The fillers 705 or supports can be circular in shape, but have a smaller diameter than the cloth brush panels (e.g., 140). In some embodiments, the fillers or supports can be made of the same material as the cloth brush panels (e.g., 140). The fillers 705 can be about ¼ inch thick, ½ inch thick, or one inch thick. In some embodiments, the fillers 705 can range from six (6) inches to twenty (20) inches in diameter.
