(23) While the assembly and method of the present application is susceptible to various modifications and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and are herein described in detail. It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular embodiment disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present application as defined by the appended claims.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
(24) Illustrative embodiments of a method and apparatus for rejuvenating lines on roads according to the present application are provided below. It will of course be appreciated that in the development of any actual embodiment, numerous implementation-specific decisions will be made to achieve the developer's specific goals, such as compliance with assembly-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.
(25) The present application is directed to a method and apparatus for rejuvenating lines and markings on roads. Although largely presented with respect to lines and markers on a roadway, it should be understood and appreciated that alternative embodiments may be configured for cleaning additional surface types, not being limited to line markers on roadways.
(26) In operation, the apparatus of the present application is uniquely configured for recirculating a substantial portion of the water used. Optionally pressured and heated water is carried by a vehicle with water storage capabilities until line rejuvenation is set to being. The water is then directed from the vehicle's storage systems through a series of hoses to the apparatus described in detail below. Although water is a preferred substance for cleaning and rejuvenating the surface, it should be appreciated that alternative substances may be used, such as a pre-treat substance used to break down oil or other pollutants often found on roadways; for the most efficient operation of the present system, any substance or chemical used should be low foam. Following propulsion of the water onto the surface, the apparatus moves over the area using a squeegee-like effect while vacuuming liquid and other material from the surface while in their emulsified state. The rear-most portion of the system is the most important for squeegee purposes, such that there is little to no substance left on the road after the apparatus passes.
(27) The vacuum system operates to remove the liquids and other material, such as dirt and debris, from the area being cleaned. The vacuum system works to remove the substances from the apparatus into the vehicle storage tank, such that the water can then be recycled and reused to spray back onto the road as the system moves along. A series of filters and/or screens may be utilized within the vehicle to remove any silt, dirt, or small rocks that may have been picked up in operation.
(28) Under the preferred embodiment, the unique water recycling capabilities of the system provide for recycling and reuse of approximately 98% of the water used during operation. It should be understood that some water loss is likely to occur when the system moves over bumps, such as potholes or road reflectors, thus causing the system to temporarily lose adequate squeegee effect. The unique configuration allows for both an increase in water utilization efficiency and a decrease in environmental impact. In additional embodiments, the system may be raised to a higher level off the surface, which may result in the need for more water and higher amounts of water loss.
(29) The unique method of rejuvenating lines on roads is designed to remove substantial amounts of dirt, debris, hydrocarbon settlement, oxidized paint, and various other substances in an efficient manner; the removal of such materials results in a rejuvenated surface, which helps to avoid the need for more costly and time-consuming projects like removing and repainting lines. Under the preferred embodiment, the apparatus is configured to clean and rejuvenate a surface at a pace of approximately four to seven miles per hour. Such pace results in a goal of covering approximately thirty linear miles in a single night, with minimal traffic impact being a goal. It should be understood that exact pace may vary depending on how many units are utilized within a selected system.
(30) Referring now to
(31) As noted, the present application may also include alternative embodiments varying in size, shape, and configuration. For example, some units may be round, square, rectangular, triangular, or a variety of other shapes. In some embodiments, there may even be additional stacked units, or units positioned at varying heights. While the apparatus of the present application is uniquely configured for use on roads, it should be understood that alternative embodiments may be adapted for rejuvenating and cleaning other surfaces, such as sidewalks, plazas, or any other large surface area susceptible to sizeable spills and gathering of dirt/debris.
(32) Each cleaning unit 101a/101b is preferably defined around its outer edges by frame 108 and skirts 107. The skirts 107 are coupled to an outer edge surface of the frame 108, such that the frame 108 edges are substantially enclosed by the skirts 107. A view from the underside of the unit, as seen in
(33) The skirts 107 are preferably made from rubber and are configured such that they have a squeegee effect on liquids and debris while moving along a surface. Although the skirt material is subject to wear while running along the pavement surface, the unique configuration of the skirts 107 and their coupling mechanism to the frame 108 allows for efficient removal of worn skirts and attachment of new skirts. It should be understood that alternative embodiments of the present application may have skirts of varying material, such as polymers, and also that some embodiments may utilize a different series of pieces designed for creating a squeegee effect. In even further embodiments a skirt system may not be necessary.
(34) Each unit 101a/101b preferably includes a spray connection 103 disposed near a central portion of a top surface of the respective unit. Spray connection 103 is preferably configured to provide a connection point between each unit 101 and a high-pressure water hose 123. Spray connection 103 is configured to direct a high-pressure stream of liquid downward to the underside of the unit 101. The spray connection 103 is further illustrated in
(35) Some embodiments of the present application may include multiple connection points similar to spray connection 103 on at least one unit 101. For example, in at least one embodiment, there is two spray connection points each connecting an external hose to a cleaning unit; the first connection point is associated with a hose configured for providing a pretreatment liquid substance to the cleaning unit; the second connection point is associated with a hose configured for providing water to the cleaning unit. In operation of such embodiment, the pretreatment substance would first be sprayed onto the surface to be rejuvenated, followed by a spray of water from the second connection point to wash the pretreatment and any dirt or debris from the surface. It should be understood that pretreatment is not always necessary; as such, some embodiments may include the capability of a pretreatment, but do not always utilize such capability.
(36) Collection tank 105 is preferably coupled to unit 101a using mounting brackets 117. Some alternative embodiments of the present invention may include various ways to couple the collection tank 105 to the unit 101. Collection tank 105 is preferably configured as a vacuum canister meant to disperse and regulate vacuum flow to all areas of the unit, and where the vacuumed materials collect in transition from the surface to a storage point.
(37) Material, including any of the liquids and waste material from the surface being cleaned, is preferably vacuumed from underneath unit 101a through a small area between skirts 107 and frame 108. The small area is defined by angled trim 111, which is preferably shaped as a triangle with two corners at the top and an open point at the bottom. The small opening in the triangle-shaped angled trim 111 is uniquely configured to prevent large debris, such as sizeable rocks and other materials from being vacuumed into the collection tank 105 and any further storage tank. Such rocks and other material are likely to damage, clog, or otherwise negatively affect operation of the system, and therefore preventing intrusion of those materials is vital to efficient operation of the system. Although unit 101b is only configured to spray substances on to the surface and not vacuum any material, it should be appreciated that alternative embodiments of the present application may include multiple units with vacuuming capabilities. Additionally, it should be understood that alternative embodiments may not utilize a triangle-shaped trim, but rather could utilize other shapes, even including a straight trim with an opening for material to travel through. Filters, screens, or other mechanisms meant for preventing unwanted material from being vacuumed may be present within the trim in some alternative embodiments.
(38) When material, including water, any pretreatment chemicals, and the dirt/debris being removed from a surface is vacuumed through the opening in angled trim 111, the material travels through hoses 109 and into collection tank 105. As illustrated, there are six hoses 109, each coupled to angled trim 111 at hose connections 113. Hose connections 113 are preferably configured to define an opening and connection point, through which material can flow from the underside of the unit 101, through angled trim 111, and into hose 109. In alternative embodiments, there may be varying numbers of hoses and hose connections, depending on the size and desired performance of the unit.
(39) Collection tank 105 also includes at least one vacuum connection 121. Under the preferred embodiment, and as illustrated, there are two vacuum connections 121 on collection tank 105, disposed on a rear portion of the collection tank 121. By positioning the connections 121 on a rear portion of the tank, vacuum hoses (illustrated in
(40) In some alternative embodiments of the present application, there may not be vacuum connections; rather, the spray arms or other rotating system positioned underneath the unit may be configured to rotate at high rates of speed to create a suction effect. Such suction can create a fan forced event in which the water and other materials is suctioned from the surface and driven into a recovery hose, or other storage device.
(41) Apparatus 100 preferably includes a connection point 119 that is configured for attaching a controlling device or maneuvering member. Under the preferred embodiment, connection point 119 extends from mounting bracket 117 in a horizontal direction, such that the connection point 119 can mate with the corresponding mounting member. In the preferred embodiment of the present application, the corresponding mounting member is a vehicle bumper mounting system (illustrated in
(42) Apparatus 100 also preferably includes a plurality of wheel assemblies 115. Each wheel assembly 115 (illustrated in additional detail in
(43) Under the preferred embodiment, the frontmost wheel assembly is positioned directly in front of the unit 101b, such that when the apparatus is being moved forward, the frontmost wheel moves over the centerline of the area to be cleaned/rejuvenated. As the preferred embodiment is configured for rejuvenating lines on roads, the frontmost wheel follows the lines to be rejuvenated; however, with such trajectory, any reflectors or bumps on the road cause the system to be lifted from contacting the surface. In alternative embodiments of the present application, there may not be a centered front wheel; with no front wheel, any bumps such as reflectors will contact the skirt or frame. There may be a type of protective device on the leading edge, such that the skirt or frame is not damaged by any such bumps. It should further be appreciated that alternative embodiments may utilize wheel assemblies that are variable in height, whether the height change be completed manually or automatically.

(47) Another notable piece now seen in
(48) Referring now also to
(49) In operation of the preferred embodiment, water flows through hose 123 and into spray connection 103. Within spray connection 103, a high-pressure beam of water travels through a center opening of the bearing or swivel and into the wand attachment 300. Within wand attachment 300, the water then disperses into each wand arm 301 or spray arm, still maintaining a single high-pressure beam within each respective arm. When the beam reaches the end of wand arm 301 and travels into wand tip 303, the high-pressure beam is then expelled though a single aperture in wand tip 303. Under the preferred embodiment, the wand tip is angled at a selected degree relative to the arm, such that when water is expelled through the aperture, rotation of the entire wand attachment 300 is generated.
(50) It should be understood that in alternative embodiments of the present application, the angles of the wand tip may vary to create different desired rotation directions and speeds. For example, some embodiments may have the wand tips of the wand attachment for unit 101a set to cause opposite rotation to the wand attachment of unit 101b, such that the two have units have counter-rotating wand attachments. It should also be appreciated that some embodiments may have varying wand attachments, such as one with wand arms including a plurality of downward facing apertures, such that some water or other liquid is released between wand base and the wand tip.
(51) Referring now also to
(52) The tires on the wheel of each wheel assembly are preferably a substantially solid material with a slight amount of air in them, allowing for substantial durability while minimizing maintenance. However, in alternative embodiments of the present application, the tires may be made of alternative materials. For example, some embodiments may include tires that are foam filled, tires that are solely filled with air, or tires that are of a solid material.

(55) Spray connection 103 preferably includes a mounting base 601, a central bearing 603, a spray connection head 605, and a shaft 606. Spray connection head 605 is disposed at a top portion of the central bearing 603 and is configured for coupling and operability with water hose 123. Central bearing 603 preferably includes apertures 602 on the side surface for securement within mounting base 601 using fasteners 604. It should be understood that a variety of fastener/aperture systems may be used within alternative embodiments of the present application, including the possibility that the central bearing is a single unit with the mounting base, such that no fastening is necessary. Positioned within the connection head 605 and central bearing 603 is shaft 606, which is configured to be rotatable within the system for purposes of facilitating wand attachment motion. Under the preferred embodiment, wand attachment 300 is coupled to a threaded portion 607 of shaft 606, such that when wand attachment 300 motion is generated, the shaft 606 rotates within the spray connection. The shaft 606 includes a center aperture 609 configured to serve as a pathway for the high-pressure beam of water traveling through the system. Although it is preferred to use the wand system described herein, it should be appreciated that alternative embodiments may use a different water distribution mechanism capable of propelling water to the underside of the unit. For example, in at least one embodiment, a central distribution node may be present that propels high-pressure spray of water from a single central location to the surrounding 360 degrees, reaching all outer edges of the bottom of the system.
(56) The main purpose of the bearings is for efficient, high-speed rotation of the wand attachment, or any other relevant water distribution mechanism configured to create an agitation. It should be understood that various types of bearings will work with any embodiment of the present invention, so long as rotatable motion is present. For example, any type of swivel bearing may be used, including hydraulically spun bearings. In embodiments with hydraulically spun bearings, it may not be necessary for the angled wand tip to aid in wand motion generation. It should be understood that some alternative embodiments of the present application may utilize other agitation inducing elements underneath the unit in a rejuvenating process. For example, in place of rotating wands expelling water, a rotary or other drum system may be used to agitate the surface to rejuvenate the markings. Other embodiments may include stationary elements, such as a wand or other shaped device, the maintains a consistent downward spray without use of rotation.
