Title: Mobile rigid insulation board scorer

Description:
FIELD OF THE INVENTION 
     This invention relates to an apparatus that is used to place scoring lines in boards, particularly insulation boards for roofing, so the larger board may be separated along the scoring lines. The invention can easily be carried or transferred to roofs for use. 
     BACKGROUND OF THE INVENTION 
     There exists a need for a mobile rigid insulation board scorer that can be carried on a roof and set up by deploying or unfolding a set of legs. 
     There exists a need for a board scorer whereby the user can place a rigid insulation board (“board”) adjacent a guide, then the board can be displaced through the scorer. 
     There is a need for a board scorer that may have a blade (rolling or static) that can cut into the board on both the top and bottom side as it is moving through the board scorer. 
     There is a need for a board scorer blade having a nylon spacer that may be disposed immediately adjacent to the blade to disperse pressure from adjacent the blade to reduce or eliminate further deformation of the board. 
     There is a need for a board scorer that has multiple blades spaced apart to score the board in separate sections. 
     Then the board can be moved to its desired location and then impacted or hit near the scoring line to break the board apart. 
     Multiple embodiments of the system are disclosed herein. It will be understood that other objects and purposes of the invention, and variations thereof, will be apparent upon reading the following specification and inspecting the accompanying drawings.

For example, the words “upwardly,” “downwardly,” “rightwardly,” and “leftwardly” will refer to directions in the drawings to which reference is made. The words “inwardly” and “outwardly” will refer to directions toward and away from, respectively, the geometric center of the system and designated parts. Said terminology will include the words specifically mentioned, derivatives, and similar words. Also, “connected to,” “secured to,” or similar language includes the definitions “indirectly connected to,” “directly connected to,” “indirectly secured to,” and “directly secured to.” 
       FIG. 1  illustrates one embodiment of the present invention, referred to as a mobile rigid insulation board scorer  10 . The purpose of the board scorer  10  is to make a small cut, or score an upper and lower surface of insulation board that is usually used for roofing. 
     An upper surface of the board  190 , and a lower surface of the board  190  is scored. The score is a linear surface cut, and the score on the upper surface is usually located opposite of the score on the lower surface. The score usually runs the length of the board. See  FIG. 8 . 
     In most cases the board is scored at desired widths so as to separate the board  190  in to desired widths. 
       FIG. 1  illustrates the scorer  10  having a support  20  to support the body  30  and other components at a height convenient for a person to place an insulation board between the body  30  and upper arm  40  that is disposed upwardly from the body  30 . 
     In one embodiment the support  20  is foldably connected to a base  180 , as best seen in  FIG. 6 . 
       FIG. 1  also illustrates a lower blade  50  and an upper blade  60 . The upper blade  60  may be slidably disposed on an upper arm  40 . The upper arm  40  may be slidably disposed on two opposed columns  90  so it may be displaced upwardly and downwardly and secured into the desired position, as best seen in  FIG. 3 . 
     A measuring device  80  may be disposed on one of the body&#39;s  30  so that the user can place the lower blades  60  or upper blades  50  at desired locations and distances. 
     As illustrated in  FIG. 1  a guide rail  70  may be disposed leftwardly and rightwardly on the body  30 . As illustrated in  FIG. 5 , there may be two (2) bodies, one may be disposed in front of the other body  30 . The guide rail  70  may assist the user in positioning, guiding, and moving the insulation board rearwardly through the board scorer  10 . The guide rail  70  is adjustable for boards of different widths. For example the guide rail  70  may adjust from a width of 0 inches to 49 inches. The adjustable guide rail  70  can be moved by relocating the bracket  170  along the lower arm  160  as the adjustable guide rail  70  is fixed to the bracket  170 . 
     As illustrated in  FIG. 2  the two (2) bodies  30  may be separated by a distance to define a channel  120 . The lower arm  160  may be disposed in the channel  120  on a base  180 . The lower blade  50  may be slidably disposed on the lower arm  160 . The upper blade  60  may be slidably disposed on the upper arm  40 . The lower blade  50  may be slid along the lower arm  160  and positioned at a desired location, and then locked in place via a lower blade adjustment means  130 . In one embodiment the lower blade adjustment means  130  may be a threaded fastener that secures the lower blade adjustment means  130  to the lower arm  160 . Or it may be a pin that enters a hole. 
     Similarly the upper blade adjustment means  140  may be slid and locked in place to the upper arm  40 . 
       FIG. 3  illustrates an embodiment of the rear of the board scorer  10 . A height adjustment means  110  is illustrated. In one embodiment the height adjustment means  110  may be a threaded handle that can screw toward the column  90  until it is secured against the column  90  to secure the upper arm  40  in place. 
       FIG. 3  also illustrates the upper blade  60  and the channel  120 . 
       FIG. 4  illustrates an embodiment of the upper blade adjustment means  140  having an Allen wrench fastener that can be rotated and contact the upper arm  40  to secure the upper blade adjustments means  140  to the upper arm  40 . Likewise the upper blade  50  being secured to the upper blade adjustment means  140  is secured in position.  FIG. 4  also illustrates a spacer  150  disposed on both sides of the upper blade  60 . 
       FIG. 5  illustrates a side view of an embodiment of the board scorer  10 . Each of the two (2) bodies  30  may be secured to the base  180 . The lower arm  160  may be secured to the base  180 . The bottom of the column  90  may also be connected to the base  180 . An L-shaped bracket  170  may be secured to the top of the lower arm  160  to extend inwardly and upwardly. The guide rail  70  may be connected to the bracket  170 . 
       FIG. 6  illustrates an embodiment of the present invention board scorer from the side and underneath. The supports  20  may be foldable and stowed entirely under the base  180  for transportation and moving of the board scorer  10 . Both bodies  30  are illustrated, one body  30  in front of the other body  30  to define a channel  120 , with the lower arm  16  disposed in the channel  120  and the lower arm  160  secured to the base  180 . The guide rail  70  is also illustrated. 
       FIG. 7  illustrates an embodiment whereby one person can place the board in the board scorer  10 , and the board  190  then slides on a conveyor  200  to be stacked one on top of the other. This allows only one person to use the board scorer  10 , rather than one person feeding the board  190  through the board scorer  10 , and a second person to receive the scored board  190 . 
       FIG. 8  illustrates one surface of the board  190  with three (3) scoring lines so the board  190  can easily be hit or impacted along the scoring lines  210  so the board  190  can be separated into four (4) separate boards.
