     BACKGROUND OF THE INVENTION 
     Power cutting hand tools, including circular saws, grinders, routers, and other power saws are useful for rapid cutting of materials or grinding of substrates against which the blade, router bit, or grinding member may be applied. Careful control of such power tools is essential to complete an accurate cut and avoid unintended damage to both material or substrate being cut and the adjacent structures. A particular problem in the current state of the art is that as a result of the substantial cutting power of modern power tools, in the event of even a momentary misalignment of the blade in relation to an intended cut line may result in significant damage to the material or adjacent structures. 
     Furthermore, it may be necessary for a user to avoid the use of various power cutting tools deemed to be especially prone to accidental misalignment when cutting or grinding certain substrates including grout disposed between tiles or stones on floors and walls. The use of more easily controlled alternative power tools may increase inefficiency and result in greater time required for work completion and consequent higher cost. 
     To help combat this problem, many power tools such as circular saws, jig saws, and routers are manufactured with an integral flat base plate attached to the primary housing of the tool&#39;s motor. During use of the power tool, this base plate supports the weight of the tool and rests upon the substrate being cut. The power tool&#39;s blade or cutting member extends past the base plate in a generally perpendicular plane relative to the base plate. In typical circular saw and jig saw design the base plate is generally rectangular and the cutting blade is parallel with two sides of the base plate. In other power tools, such as routers, the base plate is typically round in shape and the cutting bit protrudes through a hole in the center. In yet another variety of power tools, such as spiral saws and rotary tools, a collar may be removably attached over the working end of the tool that houses the cutting bit. The collar is analogous to the base plate of a router and features a flat surface that rests upon the substrate to be cut while the cutting bit extends beyond the flat surface of the collar to make a cut as the flat surface of the collar moves across a work piece. The base plate is commonly adjustable relative to the saw blade or cutting bit to allow a user to select a desired depth of cut or angle of cut relative to the base plate. 
     While the use of a base plate affixed to the power tool does aid in maintaining some degree of control over the tool, there is a fundamental limitation with this solution. Specifically, the base plate is attached to the power tool, and it therefore moves whenever the power tool is moved. As such, it is susceptible to unintended movements from the user. A partial solution to this problem that the industry has developed is the use of a detached guide rail. 
     A detached guide rail is an apparatus that is well-known in the art. A guide rail provides a means for continuously maintaining proper alignment of a power saw blade or router bit upon a material or substrate to be cut. Since the detached guide rail is not affixed to the power tool, it is not susceptible to unintentional movements by the user. Thus, the guide rail can be securely fastened to the material or substrate to be cut to provide a secure, nonmoving guide along which the power tool can move. Improved control of the tool allows completion of cuts with greater speed and efficiency. The use of a guide rail can allow a user to utilize a particular type of power cutting tool that cannot be reliably controlled without a guide rail. Guide rails are typically affixed to materials to be cut using clamps or other conventional mounting means. Once the guide rail is secured to the material, it allows a user to accurately complete a linear cut by maintaining the outer margin of the tool&#39;s base plate firmly in position by aligning it against the guide rail while pushing the power tool forward along the length of the guide rail down the material to be cut. The secured guide rail and the cut line are therefore parallel separated by the distance between the outer edge of the power tool base plate and the edge of the cutting blade or bit. 
     In the case of power router design, the base plate is round and the router bit is positioned at the center of the circular base plate. Therefore there is a consistent distance between the cutting bit and any point along the perimeter of the base plate. By keeping the router base plate against a guide rail, the router bit cuts in a straight line or a curved line in accordance with the shape of the guide rail. 
     The current state of the art with respect to cutting guides can best be appreciated by an analysis of various devices currently known. U.S. Pat. No. 4,867,425 issued to Miraglia (1989) utilizes an elongated, flat, metal plate with an upwardly oriented flange along one of the long margins that acts as a guide rail for a power saw. The metal plate is bolted to a flat piece of lumber or plastic such that the distance from the guide rail to the lateral edge of the lumber corresponds to the distance from the saw&#39;s base plate to the edge of the blade of the power tool. The metal plate with the lumber or plastic attachment is positioned where desired and affixed by clamps to the substrate material to be cut. Thus, this device requires the use of additional tools, clamps, to secure it to the material to be cut. 
     U.S. Pat. No. 7,063,000 issued to Molburg (2006) describes a similar portable metal guide bar apparatus that additionally provides integral clamping assemblies to affix the apparatus to the material or substrate to be cut. This and similar designs have disadvantages that include the additional time required for the user to apply clamps or clamp assemblies to secure the apparatus to the substrate to be cut. Additionally, guide rail stabilization to the material or substrate with clamps or clamp assemblies requires access to both a top and a bottom surface of the substrate. Thus, the substrate to be cut cannot lie flat upon the floor, nor can the substrate to be cut be part of the floor itself, such as grout. 
     U.S. Pat. No. 4,539,881 issued to Maier (1985) discloses a power tool guide apparatus that is not provided with clamps for stabilization upon the substrate work surface. In this design there is a vertical guide rail perpendicularly attached to a flat plate that rests upon the substrate to be cut. The lower surface of the flat plate portion of this apparatus is described to have “slip proof” facing material. This facing material is proposed to increase the coefficient of friction between the plate and the substrate to be cut by virtue of the forces acting upon it by the use of the saw. A subsequent patent issued to Maier, U.S. Pat. No. 4,619,170 (1986) further modifies the earlier patent design to include means to physically engage the saw base plate and the guide plate, and additionally, means by which the flat plate portion of the apparatus may be clamped onto the substrate to be cut. 
     The aforementioned designs suffer from one or more shortcomings. Those designs that require stabilization of the cutting guide apparatus to the substrate to be cut using clamps require extra time for the user to apply clamps or clamp assemblies. In addition, clamps cannot be utilized to position a guide rail apparatus to a floor or a wall when a user wishes to cut tiles or grind grout disposed in spaces between tiles or stones in a floor or a wall. Early designs rely upon slip proof material to reliably stabilize the guide plate by increased friction between the guide plate and the substrate surface. When this frictional force is augmented by only the forces resulting from operation of the power tool, this frictional force alone may not reliably prevent slippage and unintended displacement of the guide apparatus relative to the substrate during cutting operations. Errant cuts associated with incomplete stabilization of any power tool guide apparatus may result in costly damage to the substrate being cut. Finally, the surface of floor tile or wall tile is commonly quite smooth and conventional designs may provide inadequate resistance to slippage of the cutting guide when a user wishes to cut grout disposed between floor or wall tiles. 
     A key element that distinguishes various designs in the prior art is the means of stabilization or fixation of the guide rail apparatus relative to the substrate that is to be cut. Many prior art designs feature a guide rail apparatus that requires the use of clamps to affix the guide rail apparatus to the substrate. This is problematic because the use of a clamp requires that there be two sides, usually an upper and an underside so that the clamp can squeeze. The problem arises when there is no access to the underside, such as in the case of cutting grout on a floor. A clamp cannot be used, because the underside of the floor is not accessible. Those prior art designs that rely upon frictional force between the guide rail and the power tool to maintain stability between the guide rail and the substrate to be cut offer no means by which such frictional forces may be sufficiently augmented to reliably prevent movement of the guide rail and potential damage to the substrate to be cut. 
     BRIEF SUMMARY OF THE INVENTION 
     During operation of a power tool it is essential that a guide rail is continuously maintained in a reliably stationary position relative to the substrate being cut in order to complete an accurate cut and avoid inadvertent damage to the substrate or adjacent structures. One object of the present invention is to overcome shortcomings of previously proposed designs of portable guide rails and guide rail assemblies. An additional object of the present invention is provide a simple and inexpensive means of temporary fixation of a guide rail to a substrate without the need for clamps or clamp assemblies that are tightened to grip both a top and a bottom surface of the substrate to be cut. In particular, a further object of the present invention is to provide a guide rail design that may be rapidly positioned upon the surface of a substrate such as a tile floor or wall with temporary fixation that is sufficiently reliable to allow the safe use of a circular power saw to cut grout with minimal risk of damage to adjacent tiles. 
     It is an object of the invention to provide a cutting guide that guides a power cutting tool in a straight line. It is further an object of the invention to provide a cutting guide having a control plate and a connecting plate affixed to the control plate and extending in a generally perpendicular relation from the control plate. In addition, there is a guide plate affixed to the connecting plate and extending in a generally perpendicular direction from the connecting plate such that the guide plate is generally parallel to the control plate. It is contemplated that the control plate, connecting plate, and guide plate are aligned to form a plane. 
     It is yet a further object of the present invention to provide a rail affixed to the guide plate that extends upwardly from the plane formed by the control plate, connecting plate, and guide plate. The rail is securely held vertically from the plane by the guide plate. 
     It is a still further object of the present invention to provide a cutting guide having a pressure pad affixed to the top surface of the control plate and a foot affixed to the underside of the control plate. The foot can also be present on the underside of the connecting plate and guide plate, and the foot provides additional friction between the cutting guide and the surface upon which it is placed. It is also contemplated that there will be a handle affixed to the top surface of the control plate to aid in handling the cutting guide. 
     It is further an object of the present invention to provide one or more alignment rods affixed to the guide plate such that the alignment rods can be placed on or into the material to be cut. It is also contemplated that the control plate, guide plate, and rail can be adjustable in length. 
     It is further an object of the present invention to provide a cutting guide having a control plate and a lockable hinge affixed to one end of the control plate. The hinge is also connected to a guide plate wherein the lockable hinge is adjustable and can be locked into a plurality of positions. The invention also has a rail affixed to the guide plate and extending upwardly from the guide plate, such that the rail is securely held vertically. It is further contemplated that the invention can have a pressure pad affixed to the top surface of the control plate and where a foot is affixed to the underside of the control plate, connecting plate, and/or guide plate. Also, it is contemplated that the invention has a handle affixed to the top surface of the control plate. 
     It is still further an object of the present invention to provide a cutting guide having a control plate and a support affixed to and extending vertically along the length of the control plate. There are a plurality of hinges disposed along the top surface of the support and attached to a second support such that the second support can rotate about an axis defined by the plurality of hinges. Thus, the support and second support that are connected by the hinges can form adjustable angles. It is further an object of the present invention to provide a rail affixed to the second support and extending the length of the second support such that the rail rotates with the second support and can rotate to an angle such that the rail contacts the control plate in approximately a 90 degree angle and provides a surface against which a power cutting tool can be placed. Attached to the support is a beam that extends away from the support. Attached to the other end of the beam is a suction cup apparatus oriented downwardly in order to engage a surface upon which the cutting guide is placed and create suction. This functions to secure the control plate to the surface. It is further contemplated that there is a pressure pad affixed to the top surface of the control plate and a foot affixed to the underside of the control plate. The foot provides additional friction between the cutting guide and the surface upon which it is placed. It is also contemplated that the invention has a handle affixed to the top surface of the control plate.

     DETAILED DESCRIPTION OF THE INVENTION 
     The following detailed description is of the best currently contemplated modes for carrying out the preferred embodiments of the present invention. The detailed description of the embodiments of the present invention should not be read to in any way limit the scope of the present invention. Rather, the detailed description is simply to illustrate the guiding principles of the present invention. The scope of the present invention is defined by the appended claims. 
     In a preferred embodiment, the present invention provides two primary components. The first component is a guide plate with a generally perpendicularly affixed guide rail that extends along the length of the guide plate. The second component is a control plate that is rigidly connected to the guide plate such that temporary fixation of the control plate upon a work surface results in consequent fixation of the guide plate. The saw guide may be manufactured with a direct connection between the primary components or such connection may be provided by a connecting plate. The guide plate provides a flat surface along which the base plate of a cutting tool is moved while also maintaining contact with the guide rail, to thereby allow a user to cut in a straight line. When performing cuts on a horizontal surface substrate a user exerts downward force on the pressure plate of the saw guide to prevent slippage of the saw guide upon the substrate while performing a cut. This force may be provided by resting a knee on the pressure plate, by pressing downward upon a handle on the pressure plate, or both. This force may be provided by alternate means as chosen by the user. Once a cut is made, the cutting guide can be easily moved into the next position to facilitate further cutting along a straight line. 
     Referring to  FIGS. 1 through 3 , the cutting guide can include a guide plate  2  that has a generally rectangular shape with a first inner edge  4  running parallel to a first outer edge  6  and a first front edge  8  parallel to a first back edge  10  thereby defining the rectangular shape of the guide plate  2 . The guide plate  2  has a generally flat top surface and a flat bottom surface. The guide plate  2  should be manufactured from semi-rigid or rigid material in order to not move when one is using the cutting tool. The guide plate  2  can also be of varying sizes depending on the application of the cutting guide. 
     Extending perpendicularly from the top surface of the guide plate outer edge  22  is the rail  12 . The rail  12  can be an extension of the guide plate  2  or the rail  12  could be a separate piece of material affixed to the guide plate  2 . It should be appreciated by those skilled in the art that the only requirement for the rail  12  is that it must provide a rigid surface against which the base plate of a cutting tool can be placed such that the cutting tool can continuously move along guide plate  2  and maintain contact with the length of the rail  12 . The width of guide plate  2  from inner edge  4  to the outer edge  6  is manufactured or moveably adjusted such that a cutting tool blade or bit projects downward past inner edge  4  of guide plate  2  while the cutting tool base plate remains in contact with rail  12 . The power tool cutting blade or bit extends downward from the power tool lateral to the inner edge  4  of the guide plate  2  and downward beyond the bottom surface of the guide plate  2  and into the substrate to be cut. Thus, the rail  12  must provide a stable surface for the cutting tool to rest against as the cut is made. The rail  12  can be made to varying sizes and specifications depending on the intended application. The height of rail  12  is greater than the thickness of the base plate of the power tool that will be aligned with the cutting guide. Further, it should be apparent that the rail  12  could be manufactured to be removable from the guide plate  2  such that rails  12  of differing sizes or designed specifically for different tools can be attached to the guide plate  2 . Although not shown in the Figures, it should be appreciated by those skilled in the art that the guide plate  2  or rail  12  may be modified with specialized grooves, additional rails, or other effective means to engage or interlock with corresponding specialized components of the base plate of a power tool, thereby further facilitating proper alignment during power tool cutting or grinding operations. 
     Extending from the guide plate inner edge  4  near the first back edge  10  is a connecting plate  14  that has generally a rectangular shape. The connecting plate  14  has a connecting plate interior edge  16  that is parallel to a connecting plate exterior edge  18 . The connecting plate  14  extends away from guide plate  2  and connects in a rigid manner to control plate  20 . The connecting plate  14  can be manufactured from either the same or a different semi-rigid or rigid material as the guide plate  2 . It should be appreciated by those skilled in the art that a principle function of connecting plate  14  is rigid connection between guide plate  2  and control plate  20  and the connecting plate  14  can be of different sizes and shapes, including the form of a tube. Although not shown in the Figures, it is contemplated that the connecting plate could be manufactured to be adjustable, thereby allowing one to shorten or lengthen the distance between the guide plate  2  and the control plate  20 . It should also be apparent that connecting plate  14  may alternatively attach to the first inner edge  4  of guide plate  2  at or near the first front edge  8  of guide plate  2  and extend away from guide plate  2  to connect in a rigid manner to control plate  20  at a point nearer to a control plate front edge  22  of control plate  20 . 
     The Figures demonstrate a generally ninety degree angle of connection between guide plate  2  and connecting plate  14 . The Figures similarly demonstrate a generally ninety degree angle of connection between connecting plate  14  and control plate  20 . Although not shown in the Figures, it should be apparent to those skilled in the art that the cutting guide could be manufactured with connecting plate  14  attaching to either guide plate  2  or control plate  20  at any effective angles of attachment to improve ergonomic structure for a user. It is further contemplated that the connecting plate  14  angle of attachment to either guide plate  2  or control plate  20  could be manufactured to be adjustable. 
     Extending from the connecting plate  14  on the end opposite from the attachment to guide plate  2  is control plate  20 . Control plate  20  can be manufactured from either the same or a different semi-rigid or rigid material as the guide plate  2 . Said control plate  20  is generally in the shape of a rectangle with a control plate inner edge  24  running parallel to a control plate outer edge  26  and a control plate front edge  22  parallel to a control plate back edge  28  thereby defining the rectangular shape of the control plate  20 . Control plate  20  has a generally flat top surface and a flat bottom surface. Attached to the top surface of control plate  20  is a pressure pad  29  running along the top surface of control plate  20  from the control plate back edge  28  toward the control plate front edge  22  that extends for a distance up the control plate  20 . Said pressure pad  29  is a generally flat item with solid but cushioning characteristics whereon a user can rest a knee and exert downward force during cutting or grinding operations on a generally horizontal surface. A handle  30  is attached to the top surface of control plate  20  near the control plate front edge  22  such that a user can hold the cutting guide by the handle  30 , or one can use the handle  30  in conjunction with the pressure pad  29  to maintain the cutting guide in fixed position upon a generally horizontal surface to be cut. It should be readily appreciated that the size and shape of the control plate  20 , pressure pad  29 , and handle  30  can vary according to the intended use of the cutting guide. 
     As an optional accessory, the saw guide can be provided with an additional feature to aid in using the saw guide on surfaces with indentations such as grout lines. An alignment rod  32  can be permanently or removably affixed to the opposite ends of guide plate  2  lateral to first inner edge  4  through conventional means. Said alignment rods  32  are generally rigid rods of a caliber generally corresponding to the width of an intended cut line created by a power tool in conjunction with the cutting guide. One alignment rods is positioned parallel with first inner edge  4  and extends past first front edge  8 . A second alignment rod  32  is positioned parallel with first inner edge  4  and extends past first back edge  10  or out from connecting plate interior edge  16 . The distance from the rail  12  to the nearest edge of each alignment rod  32  is equivalent to the distance from the outer margin of a given power cutting tool base plate and the nearest edge of the cutting blade, routing bit, or drill bit. The length of each alignment rod  32  is generally short, with a length sufficient only to adequately aid a user in properly positioning the cutting guide. The alignment rods  32  would be placed into the grout line that corresponds with the desired cut line but a given cut with the power tool would not extend forward or backward sufficiently for the cutting blade, routing bit, or drill bit to make contact with either alignment rod  32 . 
     Turning to  FIG. 2 , the cutting guide is contemplated to optionally include a foot  34  affixed to the underside of the control plate  20 . The foot  34  would run a distance under the control plate  20  such that when the cutting guide is placed on a surface, the foot  34  would engage the surface and form a layer between the surface and the control plate  20  of the cutting guide. It is contemplated that the foot  34  would be manufactured from a substance that possessed qualities of surface friction in order to limit the amount of slipping between the control plate  20  and the surface. The foot  34  is directly underneath the pressure pad  29  on the top side of the control plate  20 . Thus, the pressure exerted on the pressure pad  29 , typically by a user&#39;s knee, would transfer directly through the control plate  20  and into the foot  34 , thereby holding the cutting guide securely in place on the surface. Likewise, the foot  34  can extend under the control plate  20  directly below the handle  30 . It should be appreciated that the foot  34  is not limited to the area of the control plate  20  but could also be utilized under the connecting plate  14  and the guide plate  2 . 
     Referring now to  FIG. 3  and  FIG. 4  which show a first alternative embodiment of the present invention where a control plate  36  is a flat item manufactured from a semi-rigid or rigid material. Said control plate  36  is generally in the shape of a rectangle with an inner edge  38  running parallel to an outer edge  40  and a front edge  42  parallel to a back edge  44  thereby defining the rectangular shape of the control plate  36 . Optionally attached to the control plate  36  is a pressure pad  46  running along the control plate  36  from the back edge  44  toward the front edge  42  that extends for a distance up the control plate  36 . An optional handle  48  is attached to the control plate  36  near the front edge  42  such that one can hold or carry the cutting guide by the handle  48 , or one can use the handle  48  in conjunction with the pressure pad  46  to maintain the cutting guide in fixed position on the surface to be cut. It should be readily appreciated that the size of the control plate  36 , pressure pad  46 , and handle  48  can vary according to the intended use of the cutting guide. 
     Affixed to the front edge  42  of the control plate  36  is a pivoting, lockable hinge  50  (hinge). It should be understood by those skilled in the art that the hinge  50  would typically be of the type that is configured in a circular shape with raised teeth that correspond to a second circular disc with raised teeth in opposite relation to the first disk. This second disk is affixed to an alternate item such that when placed together the teeth from the first half engage the teeth from the second half and thereby securely attach at varying angles. It is contemplated that the hinge  50  would be secured by a wing nut or other conventional means. 
     The hinge  50  is affixed to a guide plate  52  that also has a generally rectangular shape. The guide plate  52  has a guide plate inner edge  54  that faces the inner edge  38  of the control plate  36 . The guide plate  52  is also defined by a guide plate outer edge  56  running parallel to the guide plate inner edge  54  and a guide plate front edge  58  running parallel to a guide plate back edge  60 , each of which combine to define the generally rectangular shape of the guide plate  52 . The guide plate  52  should be manufactured from semi-rigid or rigid material in order to not move when one is using the cutting tool. The guide plate  52  can also be of varying sizes depending on the application of the cutting guide. 
     The hinge  50  allows the control plate  36  and the guide plate  52  to be configured at different angles such that the inner edge  38  and the guide plate inner edge  54  define an angle  62  defined by the hinge. Thus, the control plate  36  can be placed against a wall and the angle  62  adjusted to align the guide plate  52  with a desired cut line. This is particularly useful when cutting grout lines in flooring adjacent to a wall. 
     Extending from the guide plate outer edge  56  is a rail  64 . The rail  64  can be an extension of the guide plate  52  or the rail  64  could be a separate piece of material affixed to the guide plate  52 . It should be appreciated by those skilled in the art that the only requirement for the rail  64  is that it must provide a surface against which a cutting tool can be placed such that the cutting tool can move up and down the rail  64  while cutting. Thus, the rail  64  must provide a stable surface for the cutting tool to rest against as the cut is made. The rail  64  can be made to varying sizes and specifications depending on the intended application. Further, it should be apparent that the rail  64  could be manufactured to be removable from the guide plate  52  such that rails  64  of differing sizes or rails  64  designed specifically for different tools can be attached to the guide plate  52 . 
       FIG. 4  shows an optional foot  66  affixed to the bottom of the control plate  36 . The foot  66  could also be used on the bottom of the guide plate  52  to provide additional surface friction to aid in preventing the cutting guide from slipping on the surface. 
     Turning to  FIG. 5  and  FIG. 6  another embodiment of the present invention is shown. A control plate  68  substantially similar to the control plate  20  shown in  FIG. 1  and the control plate  36  shown in  FIG. 3  is provided. Affixed along the side of the control plate  68  is a first support  70  that extends essentially perpendicularly from the control plate  68 . The first support plate  70  is manufactured from semi-rigid or rigid material such that it is stable and does not bend or deform. A conventional hinge  72  is affixed at the top edge of the first support  70  and is affixed to a second support  74  such that the second support  74  can rotate from the first support  70 . Extending from the end of the second support  74  is a rail  76  that is substantially perpendicular to the second support  74 . The rail  76  provides a surface against which a cutting tool is placed in order to provide a stable, continuous cutting guide. It should be appreciated by those skilled in the art that the dimensions of the first support  70 , the second support  74 , and the rail  76  can be altered to varying sizes depending on the desired application of the cutting guide. The second support  74  and the rail  76  are movably attached to the first support  70  by a hinge  72  such that the rail  76  can be rotated into perpendicular alignment with the control plate  68 . Thus, the rail  76  provides a stable surface along which a cutting tool can be moved such that a linear cut is made. Although not shown, an optional spacer bar can be affixed to the control plate  68  to accommodate varying sizes of cutting tools, and move the cut a set distance from the first support  70 . 
     In order to secure the cutting guide to the surface and protect against slipping, a beam  78  is affixed to the first support  70  and extends to a suction cup apparatus  80 . The suction cup apparatus  80  is a conventional suction cup apparatus  80  with a switch  82  to engage suction. The suction cup apparatus  80  is configured to provide suction against the surface upon which the cutting guide is placed. Although not shown, an alignment rod  32  (as shown in  FIG. 1 ) can be affixed to the ends of the control plate  68  in order to provide guidance on where to align the cutting guide with respect to the desired cut. Additionally, an optional foot  86  can be affixed to the underside of the control plate  68  (best shown in  FIG. 5 ). The foot  86  and the suction cup apparatus  80  would assist in securing the cutting guide to the surface while cutting to minimize the risk of slipping. 
     Although the present invention has been illustrated and described herein with reference to preferred embodiments and specific examples thereof, it will be readily apparent to those of ordinary skill in the art that other embodiments and examples can perform similar functions and/or achieve like results. All such equivalent embodiments and examples are within the spirit and scope of the invention and are intended to be covered by the following claims.
