       BACKGROUND 
       [0002]    1. Field of Invention 
         [0003]    This invention relates to “roller units” that are used to paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to the surface area of multisided objects comprising of bars, posts, poles, shafts, spindles, railings, supports, and columns. 
         [0004]    2. Description of Prior Art 
         [0005]    The popular method of painting, staining, dusting, polishing, striping, cleaning, wiping off &amp; applying chemicals to the surface area of multisided objects is to use a standard brush that has a handle at one end and brush material pointing 180 degrees straight out of the opposite end of handle or using a standard roller that has a handle located 90 degree to the roller. With this current method one is restricted to starting at zero degrees and brushing or rolling up, down, and around multisided objects until 360 degrees is reached. This method is expensive and time consuming because it demands many strokes of the brush around the surface area of a multisided object and the operator must move around the multisided object in order to act on the entire surface area of said object. The applied coating is less uniform when using brushes and also displays brush marks. 
         [0006]    Another method is to use of rollers to apply said coatings to multisided objects. Roller coating is quick, eliminates brush marks, and provides a more uniform coating. Most single rollers are designed for flat surfaces, so they are less adequate when applying coatings to multisided objects. 
         [0007]    Prior art multi-roller devices have attempted to provide a solution to one or more problems envisioned hereby include Iuliano et al (U.S. Pat. No. 5,035,022) which discloses three coactive rollers mounted on two fixed and one detachable and adjustable support axle. The paint applicator is expensive, has a complex adjustment process that is time consuming and does not allow for roller contact all around multisided objects while the operator remains on one side object. 
         [0008]    Mclendon (U.S. Pat. No. 2,813,292) discloses two side rollers and a central roller operatively interposed there between for mainly painting cylindrical pipe. This paint applicator also requires adjustment, is expensive and does not allow for roller contact all around multisided objects while the operator remains on one side of said object. 
         [0009]    Rivadeneira (U.S. Pat. No. 6,957,470 B2) discloses four replaceable rollers pivotally attached to a handle that provides for painting of the two adjoining surfaces forming a typical 90 degree interior corner. This paint applicator is use for interior corners and thus is not suitable for coating the exterior of multisided objects. This paint applicator also requires adjustment, is expensive and does not allow for roller contact all around multisided objects while the operator remains on one side of said object 
         [0010]    Kierce (U.S. Pat. No. 4,644,604) discloses two rollers disposed in spaced parallel relationship to each other on a flexible frame which the operator must apply compression pressure to bring the rollers in contact with opposite sides of the object being painted. This device leads to operator fatigue during extended operation, does not have the right roller angle to surround multiple railings, like on a porch and is expensive. 
         [0011]    Parr (U.S. Pat. No. 3,358,312) discloses a four roller post painter where the rollers are mounted on a frame in a manner to completely encircle the object being painted. Parr&#39;s device must be disassembled each time the paint supply on the rollers need replenishing and is restricted to use on square and rectangular shaped post. The post must not be enclosed on both ends or Parr&#39;s paint applicator must be disassembled and reassembled around the post. This applicator is expensive and require adjustments. 
         [0012]    Bedford (U.S. Pat. No. 2,824,328) discloses two adjustable rollers at angles with a handle. Bedford&#39;s device doesn&#39;t allow for a plurality of roller positions around the length of the handle. The rollers and handle are all connected at the same spot restricting the rollers to be attached at one and only one spot on handle. This will only allow the rollers to form a V-shape angle sharing the same vortex and not have the freedom to be attached at a plurality of positions around the handle and have the rollers form multiple shapes like my invention. 
         [0013]    Accordingly, in spite of the various efforts of the prior art, a need still exists for an improved device that is used to paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to the surface area of multisided objects comprising of bars, posts, poles, shafts, spindles, railings, supports, and columns in a manner that is easy &amp; quick to use, low cost, disposable and where the rollers can surround multisided object as the operator stands on only one side of the object eliminating the need to waste time moving around the object to fully coat or impact the surface perimeter of the object allowing for one or multiple rollers to be attached to the handle and be positioned in the same plane as the handle while having the freedom to be adjusted to many shapes and to be placed at several locations around the handle via a slotted pattern groove situated around the handle perimeter. 
       SUMMARY 
       [0014]    In accordance with the present invention, the “multiple shape changing roller unit” mainly comprises a slotted patterned frame handle, two adjustable roller cover &amp; rod assemblies which are mounted onto said slotted frame handle. 
         [0015]    The present invention allows the operator to just stand on one side of multisided objects while surrounding the object with the invention thus reducing the amount of time to cover the entire surface area of multisided objects, due to not having to walk around to the opposite side of the said object to surround the surface of the object with my invention. My invention reduces the amount of time to paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to the surface area of multisided objects comprising of bars, posts, poles, shafts, spindles, railings, supports, and columns. My invention is very quick and simple to manufacture making it much cheaper than other devices. The two adjustable roller cover &amp; rod assemblies can be adjusted to provide many angles and positions and shapes to better surround and act on various multisided objects. The roller covers on my invention can be covered with any suitable material designed to provide effective painting, staining, dusting, polishing, stripping, sanding, cleaning, wiping off &amp; applying of liquid and power chemicals.

       Advantages 
       [0091]    From the description above, a number of advantages of the “multiple shape changing roller unit” become evident:
   (a) provides a way to concurrently paint, stain, dust, polish, strip, sand, clean, wipe off or apply chemicals (liquid and powder) to different sides around the surface area of multisided objects comprising of bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   (b) provides a faster way to paint, stain, dust, polish, strip, sand, clean, wipe off or apply chemicals (liquid and powder) to multisided objects comprising bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   (c) provides a more efficient way of painting, staining, dusting, polishing, striping, sanding, cleaning, wiping off or applying chemicals (liquid and powder) to multisided objects comprising bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   (d) provides a cheaper way to paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to multisided objects comprising bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   (e) provides an easier way to paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to multisided objects comprising bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   (f) provides a simple way paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to multisided objects comprising bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   (g) provides a reduction in the number of people require to paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to multisided objects comprising bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   (h) provides a better way to paint, stain, dust, polish, strip, sand, clean, wipe off &amp; apply chemicals (liquid and powder) to multisided objects comprising bars, posts, poles, shafts, spindles, railings, supports, and columns but not limiting to the aforementioned group of objects;   
 
       Operation (Adjustable Multisided Roller Brush) 
       [0100]    The first step would be to determine what application the “multiple shape changing roller unit” is going to be used in. This would determine which roller material you needed. If you were painting, staining, dusting, polishing, striping, cleaning, wiping off &amp; applying chemicals (liquid and powder), drying, sanding, or scraping each of theses different operations would require you to pick out a different roller material for that specific operation. Once you have decided what roller material you need for the specific job, such as needing a painting roller material for painting porch railing, you would then be ready to start using the “multiple shape changing roller unit”. 
         [0101]    An operator would adjust both roller cover and rod assemblies to the proper shape for the specific object the roller cover will act upon. The bolt &amp; wing nut for the roller cover &amp; rod assembly will then be tightened to the desired position. 
         [0102]    An operator would then put the slotted patterned frame handle of the “multiple shape changing roller unit” in the palm of his hand and wrap his fingers around the handle. While holding the “multiple shape changing roller unit”, dip the roller covers into the paint, stain, polish, stripping compound, or other chemicals (liquid and powder). Use a special pan to wipe off excess coating from the roller covers, before application, to ensure uniform coating is left on the roller covers without coating dripping from the roller covers. If it is a dusting, sanding or wiping operation where no coating will be applied to a multisided object then there will be no need to dip the roller covers into a substance or coating. 
         [0103]    Place the roller covers around the multisided object. After the roller cover opening is around the multisided object, proceed to move along the right surface area length of the multisided object to ensure that the rollers are applied around a 180 degree section of the entire surface area length of the right side of the multisided object. 
         [0104]    As you use the handle to apply pressure against the multisided object with the roller covers, the roller covers will rotate as you move up and down along the surface area length of the multisided object. Then while standing on the same side of the multisided object, flip the multi-head opening so that the opening facing the opposite direction. Then proceed to roll along the left surface area length of the multisided object to ensure that the coating is being applied to the other 180-degree section of the surface area length of the left side of the multisided object. 
         [0105]    The roller covers should form a loop around the multisided object allowing you to apply liquid or powder to part or all of the surface area of the of the multisided object. Sometimes it may be necessary to flip the “multiple shape changing roller unit” over causing the roller covers to face the opposite direction so that the other sections of the multisided object can also be acted upon by the roller covers. This application can be repeated until the entire surface area of the multisided object, 360 degrees around, is covered by the roller covers ensuring that the liquids or powder on the roller covers is applied to the multisided object&#39;s complete surface or if no chemicals are used the roll material has acted on the entire surface of the multisided object. This can all be done from standing on one side of the multisided object. 
         [0106]    In the dusting, drying, sanding and surface stripping applications the same process as above is repeated except there is no liquid or power being applied to the multisided object. The roller material of the roller cover is only being applied to the surface area of the multisided object and these different roller materials act on the object to dust, dry, sand and strip the surface area of the multisided object. This process is repeated until the entire surface area of the multisided object, 360 degrees around the entire surface area of the object is dusted, dried, sanded, or stripped.
