Title: Clear Vinyl, Roll Down - Roll Up Flat Punching Bag Sheet

Description:
BACKGROUND OF THE INVENTION 
     Generally, punching bags are typically bulky in form and filled with various materials into a leather bag that hangs from an overhead beam, punching bags are typically found in fitness centers, gyms and homes, a punching bag is a devise for hitting with a closed first in the art of boxing, the problem with hitting a heavy punching bag is injury. Most injuries consist of sprang wrist, broken fingers, broken wrist, swollen hands, and results in lost of work and incurs expensive medical cost. This style of punching bag is not suited for everyone. 
     Other familiar types of punching bags are smaller and also hang from above beams that are designed for speed punching, there is also an air filled type of punching bag filled with sand at the bottom of the unit that sits on a floor, and other styles of punching bags are hand held pads, one person would hold the pads and the other boxer person would punch the pads. 
     As a result, existing punching bags are problematic, they&#39;re heavy weighted, bulky, persistent occurring injuries, and require a large area of space, in general, existing punching bags come in many forms and styles, no matter what the form or design is, all of the known styles and types of punching devises are categorized as a punching bag, the present invention shall also be categorized as a punching bag, in its conceived embodiment and constructed form. 
     BRIEF SUMMARY OF THE INVENTION 
     Initially the present invention relies on a single sheet of clear vinyl, unlike ridged hard clear plexi-glass, the clear vinyl is soft, thin, flexible and highly durable. Because the clear vinyl is soft and flexible, it avoids injury when it is struck, being portable, light weighted and because it rolls down and up the flat punching bag sheet can be stored in the place where it is installed using virtually no space. 
     The present invention is a concept embodied in the art of shadow boxing. A boxer warms up by pretending to punch at their shadow without any contact, this is known as shadow boxing. 
     The present invention allows the shadow boxer to strike the clear vinyl flat punching bag sheet with knuckle contact instead of just punching at open air space. 
     The clear vinyl sheet combined with a silhouette graphic image inverted on the back side of the clear vinyl sheet comprised with other components becomes a roll down, roll up flat punching bag. The inverted graphic image enhances the users ability to precisely strike various points of contact. 
     The above and other features of the invention including various novel details of construction and combinations of parts, and other advantages, will now be more particularly described with references to the accompanying drawings and pointed out in the claims. It will now be understood that the particular device embodying the invention are shown by way of illustration and not as a limitation of the invention. 
     The principles and features of this invention may be employed in various embodiments without departing from the scope of the invention.

     DETAILED DESCRIPTION OF THE INVENTION 
       FIG. 1 , is a schematic drawing showing a front view of the invention rolled down in its full constructed form including various components identified with numerals comprised of the invention. 
       FIG. 2 , is a schematic drawing side view of the invention rolled down in its full constructed form including various components identified with numerals comprised of the invention. 
       FIG. 3 , is a schematic drawing rolled up side view of the invention. 
     The present invention illustrated in  FIG. 1, 2, 3 , in its preferred embodiment relies on a single sheet of clear vinyl product type from Continental Plastics Company Wheelings Ill., 60090. 
     The clear vinyl sheet is preferably 28″ wide, but not limited to being of a lesser width of 22″ or of a greater width of 36″. The clear vinyl sheet is preferably 48″ vertical length but not limited to being of a lesser length of 24″ or of a longer length of 72″. 
     The preferred gauge of the clear vinyl sheet is 0.020, but not limited to being of a lesser gauge of 0.008, 0.010, 0.012, 0.016, or of a thicker gauge of 0.030, 0.040, 0.080. 
     The clear vinyl sheet is cut to a preferred size as noted above, it is then folded over at the top and can be sewn with thread or heat sealed or PVC cement fastener # 115  A, creating a pocket # 113  approximately 1″ I D.  FIG. 1.2 . The bottom edge of the clear vinyl sheet is sewn over with thread or heat sealed or PVC cement fastener # 115  B, creating a pocket # 114  approximately  1 . 5 ″ ID.  FIG. 1.2 . 
     A strip of velcro # 116  preferably 10″ in length but not limited to being of a lesser length or of a longer length is sewn onto the back side of the clear vinyl sheet # 121  at the top center under the pocket. # 113   FIG. 1, 2 . 
     A strip of velcro # 118  preferably 1″ is sewn to the front side of the clear vinyl sheet # 120  at the top center under the pocket. # 113   FIG. 1, 2, 3  . 
     The longer velcro strip # 116  can be connected the smaller velcro strip # 118  securing the devise when it is in a rolled up position.  FIG. 1, 2, 3 . 
     The longer velcro strip # 116  detaches from the smaller velcro strip # 118  allowing the clear vinyl flat punching bag sheet to be rolled down.  FIG. 1, 2, 3 . 
     A ¼″ polyethylene plastic tubing # 12   FIG. 1, 2, 3  a product from 
     Trivantage Corporation Glen Raven, N.C. item #578095 is cut to fit the width of the clear vinyl sheet it is then inserted into the top clear vinyl sheet pocket # 113  and together can be inserted into the aluminum molding track # 110  item # 555  from Trivantage Corporation, that is no wider or lesser than the preferred width of the clear vinyl sheet. 
     The 90 degree aluminum molding track # 110  is pre-drilled with two or more screw holes. # 126   FIG. 1, 2, 3 . 
     Preferably metal weights # 124  from one ounce to ten ounces but not limited to a lesser ounce or a greater ounce are then inserted into each corner of the bottom pocket # 114  and is sewn or heat sealed or PVC cement fastener # 115  B closing the sides of the bottom left and right pocket # 114  locking in the weights.  FIG. 1, 2 . The weights # 124  are necessary so that when the clear vinyl sheet is punched it creates a drag effect or resistance to the contrary. 
     An inverted graphic # 122   FIG. 1, 2  is applied to the back side of the clear vinyl sheet so that when viewed from the front  FIG. 1, 2  it appears normal. 
     The advantage of the graphic being inverted on the back side of the clear vinyl flat punching bag sheet # 121  protects it from being worn off, or damaged when struck 
     The Inverted graphic image can be silk screened, or vinyl laminated, or digital printed, or rolled pressed, or laser etched, or stenciled, or any method of graphic application that is adequate for the manufacturer. 
     When fully constructed, including all the components comprising of the clear vinyl roll down-roll up flat punching bag sheet invention, detailed in various pages of the specification, is designed to be installed using the screw attachments on the underside aluminum molding track fastener # 110  pre-drilled holes # 126  (i.e.) inside a doorway upper inner frame, preferably a closet but not limited to other options. 
     How to use the invention is made simply by detaching the velcro strap # 116  from the velcro strap # 118  and roll down the clear vinyl flat punching bag sheet, it is now ready for the user to strike or punch the clear vinyl flat punching bag sheet. 
     The invention, when the user is finished, can now be rolled up, and the velcro strap # 116  can now be re-attached to the velcro strap # 118  storing the clear vinyl flat punching bag sheet for later use.  FIG. 3 .
