           [0004]    2. Related Art  
           [0005]    The prior art as exemplified by the other patents show various platforms which can be mounted to the flat bed of a truck, as well as certain saw holders which are shown mounted either to the bumper or in the bed of a truck for holding saws.  
           [0006]    None of these prior art references provide for a work surface similar to that provided by two spaced sawhorses. Nor does the prior art suggest a saw horse which can sit onto or over the raised sides, tail gate or rear panel of a flat bed truck. The key elements are a pair of cutting surfaces, each of which cutting surfaces having an exposed end, and a bracket for holding the cutting surface so that the exposed ends are held parallel for cutting. An additional improvement is to use, as at least one anchor for at least one bracket as being the tailgate of a truck.  
           [0007]    A saw horse type cutting surface is a surface which comprises at least two lengths of cut material (cuttable material such as wood) spaced at a desired distance, each being on approximately the same level from the ground level on which a piece of work (such as a length of wood) may be placed for cutting.  
           [0008]    The prior art shows several surfaces attachable to the rear of a vehicle. The present invention differs from those in that they do not provide a holder for a cutting surface, and in most cases, do not contain parallel cutting surfaces so that they may be used in the same manner as a conventional saw horse.  
           [0009]    The present invention provides a way for providing a transportable saw horse, which may be attached to a vehicle, and preferably the tail gate of a vehicle. Other art, such as U.S. Pat. No., 5,267,748, utilizes the rear tail gate hitch having a single tool platform to which a work tool may be secured. The inventive concept embodied in the prior art deals with various types of tables and related structures.  
           [0010]    The prior art does not describe two parallel cutting surfaces supported by a vehicle for use as cutting surfaces.  
         GENERAL DESCRIPTION OF THE PREFERRED EMBODIMENT  
         [0011]    A portable version of the preferred embodiment comprises a saw horse type cutting surface as described above held to a vertical surface, such as the side or tailgate of a truck by a mounting means. In this embodiment, the mounting means has a bracket engaging on its inner surface, possibly, with padding along an internal surface, which can fit over or onto the vertical surface and tighten in place. The mounting means or support provides a surface for mounting a bracket means or beam which may be made in part, of cut material (primarily wood) or may receive a cut surface made of cut material. The cut material, such as a wooden two-by-four, provides a saw horse-type cutting surface when two of these elements are in place.  
           [0012]    Hence, in the preferred embodiment, there are two mounting means supporting two brackets holding two cut surfaces. In this way two saw horses are provided.  
           [0013]    It is therefore an object of this invention, to provide for a portable saw horse which may be utilized wherever a raised wall is present.  
           [0014]    It is further the object of this invention to provide a saw horse which may be mounted on the tailgate, receiving hitch or side of a pick-up truck.  
           [0015]    It is further the object of this invention to provide a sturdy, stable surface for cutting in a variety of environments.  
           [0016]    It is further the object to provide a portable surface which can be utilized as a mounting for a table, shade, scaffolding, table saw, drill or for other purposes consistent with the disclosure set out herein.  
           [0017]    These and other objects and improvements of the invention will become more clear from the detailed description of the preferred embodiment set forth below, as well as the figures, in which like parts have similar numbers.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0030]    As can best be seen by reference to FIG. 9, the invention comprises a bracket means for holding a cutting surface wherein the cutting surface  1  is preferably a two by four and wherein the bracket means is preferably a bracket  2  held by a support means, here two legs, a first primary leg  4  and a secondary leg  20 . These are connected by a top leg  39 . In the embodiment shown in FIG. 9, each of the two bracket means comprises a primary leg  4 , a secondary leg  20  and a top leg  39  which here, is a welded integral part of the secondary leg  20 . Pads  14  may be provided to ease the contact between the legs and the vehicle tailgate (shown in FIG. 1). The primary leg  4  has primary leg holes  18  capable of receiving a straight or locking pin  47 . An example of a locking pin is shown in FIG. 10. A primary leg extension  21  allows for the length of the primary leg  4  to be extended. The primary leg extension  21  fits within the primary leg  4  and has holes  49  which may also receive a locking pin  47  to fit the length of the extension  21 . A base plate  35  has a L-clamp  56  attached to the base plate  35  which can hold the device to a vehicle bumper  9 . The base plate  35  is secured to the primary leg extension  21  by a countersunk bolt  63  and may have a pad  64  over the base plate  35  to even out the height relative to the L-clamp  56 .  
         [0031]    A bolt  7  is used to vary the angle at which the primary leg  4  sits against the vehicle by moving the primary leg  4  away from the tailgate  11  as the bolt  7  is moved towards the tailgate  11 . The primary leg  4  is threaded so that the bolt  7  may turn through the threading to push against the tailgate  11 . At the end of bolt  7  is a pad  6  which serves to cushion the bolt  7  as it presses against the tailgate  11 . A locking pin  47  (which may be replaced with a bolt as shown in FIG. 1) fits though the hole  60  in the c-clamp  53  which fits around the primary leg  4  and is secured to the bracket  2 . The hole  18  is lined up with a primary leg hole  48  at the desired height. It could also attach to the secondary leg in other embodiments. A second lower pin  47  (or the same locking pin  47 ) is used to fix the position of the primary leg extension  21  by passing though one of the extension holes  49  and primary leg holes  18  in this embodiment.  
         [0032]    At the termination point of the extension is a base plate  35 . As shown in FIG. 11, the base plate  35  defines a slot  55  which serves to receive a bolt  54  which moves within the slot  55  to position L-clamp  56  which secures of the primary leg to the bumper. The base plate may turn about pin  63  in either direction to secure from the front or rear of the bumper.  
         [0033]    This shape allows the primary leg  19  to rest on the bumper  9  of the truck to which it is mounted. Secondary leg  20  lies on the opposite side of the truck tailgate  11  from the primary leg  19 . Top leg  39  fits over the top of the tailgate  11  and through a hole in primary leg  4  to tighten the primary leg  9  and secondary leg  20  against the tailgate  11  as shown in FIG. 10. Secondary leg  20  need only be long enough to provide a surface to support the cane shaped structure thereby defined. Front scaffold hole  23  and rear scaffold hole  52  may be provided to receive scaffolding (shown as  24  in FIG. 1) as described in more detail in reference to FIG. 2.  
         [0034]    The attached drawings show several different embodiments of the invention. In all cases it is envisioned that two separate cutting surfaces  1 , preferably two by fours, will be held approximately parallel so that the combination forms a sawhorse type arrangement.  
         [0035]    In its broadest embodiment, the invention is nothing more than a bracket  2  for holding a cutting surface  1  to an attachment surface, in the shown embodiments, a tailgate  11 . It can easily be seen that the sawhorse in the various embodiments shown could mount to different locations on a vehicle, the main invention set out herein. However, by describing the specific structure (FIG. 8 and  9 ), it can be seen that this specific type of bracket may fit over boards parallel to the ground and held up by nails into the frame at a house being framed. This would be desirable where, for example, it was desired to build a roof over a frame or to have a sawhorse within a frame. To accomplish this, a board is nailed parallel to the ground on studs of the frame and then the sawhorses described herein are put onto the board, just as if a tailgate was being used.  
         [0036]    The attachment means for holding the bracket  2  is described herein in several different embodiments. In FIG. 9 it is a c-clamp  53  fitting around a primary leg  4  where the c-clamp  53  is attached to the bracket  2  by a joining weld.  
         [0037]    In FIG. 8, the c-clamp is replaced with a jack  50 , such as that which is found on standard automobile jack. With a jack, the height of the bracket may be adjusted or the height of the bracket  2  adjusted even when fully loaded by using a leveraged arm  51 . Here, a bolt  47  fits through a nut  48  to secure the position of the secondary leg  21  relative to the primary leg 4. The slots  15  shown in the primary leg  1  are engaged by jack  50 .  
         [0038]    Also, FIG. 8 shows an embodiment where the primary, top and secondary legs are a single unit. This would be preferred where only a single sized tailgate was used. Here, the adjusting bolt  7  with pad  6  is on the secondary leg as opposed to the primary leg. Padding  14  is also used in this embodiment.  
         [0039]    The jack  50  might be replaced with other adjusting mechanisms. One example would be to have an adjusting bolt within the primary leg  4  which is rotated by a handle outside of the primary leg. The length of adjusting bolt would rotate and would run parallel and within the primary leg length. In this way, the bracket could be mounted to an adjusting nut which was  11  fitted onto this adjusting bolt. A the bolt was turned, the height of the bracket would vary as the nut holding the bracket moved up and down the bolt.  
         [0040]    As can be seen, the bracket defines holes  18  through which a nail or screw may be driven to secure the cutting surface  1 . The attachment surface shown in FIG. 1 is the tailgate  11  of a truck. Any similar surface would provide for a different embodiment, but is considered herein. For example, using a board nailed to a frame providing a similar surface for attaching the primary, top and secondary legs.  
         [0041]    [0041]FIG. 7 shows the use of a receiver hitch  30  for receiving a receiver hitch beam  34  which in turn holds t-bar  36 . Support beams  31  extends upward from the t-bar  36 , supported from the ground on one or more base plates  35 . The primary leg  4  then is attached to this support beam  31 . Extension beams  37  supported by base plates  35  may be provided to lengthen the sawhorse spread between two or more primary legs  4 . The extensions have extension pegs  44  which may fit into extension holes  49  to extend the length and add primary legs  4  and their corresponding brackets  2 . As can be seen in FIG. 7, the bracket  2  has atop  40 , a left side  57 , right side  58  and bottom  59 . The forward top portion of the left side  57  and right side  58  slant down toward the bottom  59  so that progressively more of the cutting surface  1  is exposed.  
         [0042]    The bracket  2  has one or more holes  18  into which a bolt may be inserted to hold the board or other cutting surface  1  in place within the bracket  2 . A hinged top  41  is also shown which would be an alternative or addition to the top member  40 .  
         [0043]    In all of the embodiments, it is envisioned that there would be two brackets  2 , having longitudinal lengths which are parallel to one another, and separated by a distance of at least two feet (60 centimeters) so as to hold two boards out from the attachment surface tailgate  11  so that the two boards  1  function essentially like a saw horse. However, this distance, between cutting surfaces (boards)  1  could vary from no more than 6 inches (15 centimeters) outward.  
         [0044]    [0044]FIG. 1 shows one embodiment of the invention. The invention may described as a mounting means, here a primary support  4  which holds a bracket  2 , here in the form of a length of channel iron having a longitudinal length. The channel iron bracket  2  defines a slot  3  into which a two-by-four or similar cutting surface  1  may be inserted. The channel iron is mounted on a cane-shaped support (like shown in FIG. 8) having a primary leg  4 , a top leg  39  and a secondary leg  20  which here are molded together in a single cane-shaped support. The bracket  2  has a brace arm  8  which may rest on the bumper  9  of the pick up truck or against the support  4  or against the ground. The mounting of the bracket  2  to the support  4  may be by a weld or by a hinge so that it may swivel out as shown in FIGS. 3, 4 and  6 . When a swivel is used, the support needs to swivel out at least 90 degrees in the preferred embodiment from the plan formed by the face of the tailgate  11 .  
         [0045]    While in FIG. 1 the secondary leg  20  merely hooks over the tailgate the secondary leg  20  may be long enough in order to reach the flat bed of the truck. As shown in FIG. 8, this could be done with a secondary leg extension  22 .  
         [0046]    The brace arm  8  may be made adjustable in length, so that it may brace the bracket  2 . This brace arm may run from the bracket  2  to the primary leg  4  (as shown in FIG. 1), or it may run to the bumper  9 , or it may run more or less straight down to the ground (as shown in FIG. 4), to support the rear of the bracket  2  against the ground. In FIG. 4, this brace arm  8  is shown going to the ground. It may also rest on a wheel to allow the sawhorse to move with the truck.  
         [0047]    This brace arm  8  may either be fixed or may be hinged at the point of attachment to the bracket  2  as shown in FIG. 3 and FIG. 6. It may attached to one or alternatively at all three locations set forth above.  
         [0048]    Since the beam  2  is desirable as a steady surface, some mechanism could be provided in order to hold the support  4  in place and to adjust the angle of this relative to the ground.  
         [0049]    Several alternatives are present for this.  
         [0050]    The simplest, would be to have a bolt  7  push a pad  6  against the tailgate of the truck to which the device is mounted as shown in FIG. 8 or to use the brace arm  8  to vary the angle.  
         [0051]    To properly fit the support  4  to the tailgate the shape of the support may correspond more closely to the surface over which it fits, so that it tightly fits in place, either with or without a padding to enhance the fit. Also, the entire support top may be hinged so that the distance between the primary legs to the secondary legs can be tightened in order to draw the primary leg to the secondary leg, sandwiching the truck bed between the two (as shown in FIG. 9). Similarly the bracket  2  could be attached by way of hinges  17  allowing the angle between the tailgate and the bracket to change. To prevent undue damage to the truck in either embodiment, an inner pad  14  is envisioned to cushion places where the support  4  comes in contact with the truck and where the primary leg or secondary leg comes in contact with the truck or the bumper.  
         [0052]    The invention is to be used as a saw horse. The brackets themselves must be made of a material which can be cut or they must provide a slot  3  or the equivalent of the slot  3 , in order to mount a cuttable block  1  which is preferably a two-by-four or four-by-four, depending on the size of the sawhorse desired. The slot shown in FIG. 7 has a top  40 , a left  57  and right  58  side and a bottom  59  which define the slot  3  into which the cutting surface  1  may fit. A hinged top  41  is  11  an optional part to better secure the cutting surface  1 .  
         [0053]    In the preferred embodiment, the slot  3  allows for an enclosed portion of a two-by-four cutting surface  1  of sufficient length to be slid within the slot  3 . The remainder of the two-by-four extends out of the slot  3 . The two-by-four may be tightened in place utilizing a screw-type mechanism so that the boards do not slip out of the grooves. Alternatively, the slots can have sufficiently small tolerances, so that the boards (cutting surface  1 ) are held tightly, or the boards may be held more loosely in these slots  3 . As shown in FIG. 7, one or more holes  18  in the bracket  2  may be present in order to allow for the board to be secured by way of a screw or nail or bolt which fits through the holes  18  into or onto the board  1 . FIG. 1 shows a slot which is only enclosed on three sides. As can be seen, these slots are to hold boards which are less than ten inches (25.4 cm) across, although they are preferably six inches (15.24 cm) or less and greater than one inch (2.54 cm).  
         [0054]    As shown in FIG. 2, top band  12  and bottom band  13  may both be put in place in order to hold the a first primary leg  4  and a second primary leg  4   a  in place and to fix the distance from one bracket  2  to the next bracket  2   a . While these supports are shown on the primary legs, they may also be mounted to the top leg  39  or to the brackets  2  and  2   a .  
         [0055]    These bands  12  and  13 , may also allow for the length between them to be adjusted.  
         [0056]    As shown in FIG. 2 a board  10  may be placed over the beams, once in place, in order to provide a table surface on which to work. In addition, the support  4  may define a scaffold hole  23  at the top into which a scaffold leg  24  may be inserted. The scaffolding provided may support various implements  25  using scaffolding and may support a shade  26  so that the work done is done out of direct sunlight. The combination of the cutting surface  1  and board  10  may be replaced with a table saw or drill or similar device. While this would be a significant departure from the inventive concept embodied herein, it is a possible use of the bracket system herein described.  
         [0057]    As shown in FIG. 8, leg  4  or  20  may have an adjustable extension  21  and  22  respectively, in order to allow a single device to be mounted on trucks having tailgates of various sizes. This extension may be, as in the preferred embodiment, a leg of variable length, mounted to the bottom of either primary leg  19  or secondary leg  20 .  
         [0058]    The primary leg  4  defines a height adjustment means for varying the height of the bracket. In the preferred embodiment this adjustment means comprises a series of holes. The bracket  2  is held in place in the embodiment shown in FIG. 1 with a bolt  17 . However, any height adjustment means such as a screw, hydraulic jack, mechanical jack or the like may be substituted. In one concept the bracket could be mounted to a nut which traveled on a threaded bolt which could rotate within the primary support. As the nut travels up and down this bolt, the position of the bracket changes.  
         [0059]    There are a number of alternate methods of mounting the beam to the primary leg which would include a permanent welding of the beam in place, the placement of the beam along the set of tracks (such as those used in shelving or specialized tracks for this particular use). Similarly, it could be secured at two or more points by three or more bolts  17  or the equivalent thereof.  
         [0060]    Alternatively, once the height was determined for a particular set or a particular vehicle, it could then be either welded in place or even glued in place with the proper technology.  
         [0061]    Similarly, there could be a groove defined along the length of the primary leg  19  and a securing mechanism would provide that the bolt could slide within that groove, and then be wide enough or have a washer which was wide enough to prevent it from moving completely out of the slots which would provide for a greater degree of adjustment as shown for the base plate  35  in FIG. 11.  
         [0062]    Where an embodiment such as that shown in FIGS.  3 - 6  is used, it would be preferable to have the height of the pivot  28  changeable along the truck tailgate as by having rails (FIG. 5) serving as primary supports  4  along which pivots or brackets move on c-clamps  53  fitting around the rail type primary supports  4 .  
         [0063]    Once two of the supports and brackets are in place, and boards are placed within the slots in the beams and a saw horse or work surface is provided. As described in the invention, it can be seen that although these beams could be uneven; in the preferred embodiment, they would be at the same level so as to provide an approximately flat cutting surface.  
         [0064]    A level could be utilized in order to assure that they provided a flat surface or where the ground where the user stood was uneven, the height could be adjusted in order to provide a surface consistent with the perspective of the user. The distance from the ground should vary in order to provide an acceptable height from which to work.  
         [0065]    [0065]FIGS. 3, 4,  5  and  6  show methods of modifying the tailgate itself to act as the support  4  for the bracket  2  and brace  8 . As shown in FIG. 5, the tailgate itself may provide recesses  15  into which the bracket  2  fit when not in use. As shown in FIG. 5, the brackets may be mounted on pivots  28  adjustable on support holes is so that they may swing out into place to receive a cutting surface  1 , here a board.  
         [0066]    A tailgate opening  29  is shown through which the board  1  can slide onto the truck bed and the truck bed and tailgate opening  29  function as a bracket. As shown in FIG. 4, the brace  8  may be located below the bracket  2  and run to the ground so as not to interfere with the cutting area.  
         [0067]    In FIG. 4 the brackets  2  mounted on c-clamps  53  slide over primary supports  4  and  46 , fitted through holes  15  and  60 . The primary supports  4  and  46  slide within rails  65  built into the tailgate  11 . FIG. 5 shows where the brace may drop down vertically so that the bumper  9  provides the brace  8  for the bracket  2 . FIG. 5 shows holes  18  to secure the cutting surface  1  in the bracket slot  3 . In addition, there is a tailgate opening  29  through the tail gate  11  which allows the cutting surface  1  to be moved in and out of the trailer bed when the bracket  2  is lowered. This tailgate opening  29  may also hold a portion of the cutting surface  1  so that it does not fall downward when pushed down at the far end from the bracket  2 . When the bracket  2  is folded into the tail gate  11 , the tailgate openings  29  are shut off.  
         [0068]    While the invention is primarily designed for use with a vehicle having a tailgate 11, it can be seen that the attachment surface shown as the tailgate  11  could easily be the side panel or front panel of the vehicle.  
         [0069]    In order to lower the level of the cutting surface further, FIG. 6 shows how a tail gate may have the cutting surface on the inside face. In this embodiment, the tail gate would have to be constructed so as to fold down below the bumper. This could be done by modifying the construction of the bumper or by adding a second tailgate containing the invention behind the primary tailgate so that this mechanism would function properly.  
         [0070]    Yet another example of how this may be practiced, shown in FIG. 7 allows for the bracket means to be mounted onto the receiver hitch  30 . Here the bracket is brought out onto an extended system supports holding primary supports for larger projects using the vehicle as a ready anchor. A similar hitch mounted to the front of the vehicle could also be used. In FIG. 7, the tailgate is not affected. Instead the bracket  2  is mounted by way of the receiver hitch  30  below the bumper. The primary support  4  is mounted on a support beam  31  by way of a joining means which here comprises a hole  33  in the bottom of the support  4  into which a post  32  in the support beam  31  is inserted. The support beam  31  has a support foot  35  much like the brace arm  8 . The support beam is attached to a receiver hitch beam  34  by way of a t-bar  36 . This provides for greater spacing between the two brackets  2 . The length of the t bar, and the ability to provide for more brackets  2  is provided by having extension beams  37  which may have beam posts  39  which may be inserted into beam holes  38  in the t bar  36  or in other extension beams to form a matrix of support beams and corresponding brackets  2 . Since these support beams  21  may have scaffolding holes  23 , a matrix for scaffolding is also provided.  
         [0071]    As shown in FIG. 7, the bracket is modified so as to have a top portion which may be sealed at the rear with a roof  40 , or a hinge  41  holding a cap  42  over the top of the rear portion of the slot  3  in bracket  2  so as to better secure the cutting surface  1 .  
         [0072]    There is a receiver hitch beam foot  43  which can be used to keep the sawhorse brackets  2  in place after the vehicle is used. There may also be extension feet  44  to support the extensions  37  which may be used to extend the length of the t-bar  36 . The t-bar  36  as shown runs in either direction from the receiver hitch beam  34 . It is obvious, however, that it may run in only one direction from the receiver hitch, either left, right or back. The only requirement is that either the receiver hitch beam  34  itself or the t-bar  36  hold at least two supports  4  so that a saw horse arrangement is possible.  
         [0073]    [0073]FIG. 8 shows a close up of an alternative support/bracket arrangement shown in FIG. 1. In FIG. 8, at various locations, the holes  15  and  60  are rectangular and corresponding latches  60  are attached to the side (although they could be on the back or bottom) of the bracket  2  so that the beam latches  60  use the side of the brackets  2  and the weight of the brackets  2  to hold the bracket latched in place. Traditional car jacks function in this same fashion. Any jack-type arrangement, such as a hydraulic jack or a car-type jack could be utilized in order to raise and lower the height of the beam  2  so as to provide greater adjustment and to allow the level of the beams to be moved without effort when loaded. A bolt  47  through a nut  48  in the primary leg  19  and secondary leg  20  pass into holes  49  in the extensions  21  and  22  to adjust the height. A jack  50  is used to adjust the height as with a standard jack used on an automobile using a jack arm  51 . A secondary scaffold hole  52  is available to allow square scaffolds to be erected in conjunction with scaffold hold  23 .  
         [0074]    All of the embodiments shown hold the cutting surface of the board at approximately 90 degrees to the face plane of the tailgate  11 . However, a lesser angle might be utilized and still accomplish the desired result. This angle would preferably be for 30 degrees to 90 degrees. Similarly a single bracket might be used instead of two as long as a space for cutting was formed, although this would result in a significantly different invention. In the present embodiments, the ability to alter the spacing of the two cutting surfaces is a significant improvement.  
         [0075]    In one embodiment, there would be a rack folded into the tailgate which would drop so that one part was parallel to the bumper. The second part would drop down past the bumper and perpendicular to the bumper to the ground, and a third part, which would be adjustable in height, would be the bracket, which could be raised and lowered relative to the part went to the ground from the tailgate. Each of the parts coming off of the tailgate could be made in such a way that they folded within the other part and dropped out in a hinge-type mechanism.  
         [0076]    Because many varying and different embodiments may be made within the scope of the inventive concept herein taught and because many modifications may be made in the embodiment(s) herein detailed in accordance with the descriptive requirements of the law, it is to be understood that the details herein are to be interpreted as illustrative and not in a limiting sense.
