RELATED ART
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.
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.
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.
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.
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.
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
The invention comprises a modified tailgate to receive sawhorses which mount to the tailgate as shown in the following disclosure in more detail. In addition, the tailgate provides for a position for mounting a saw or other power tool to the tailgate. Most specifically, the tailgate defines an opening to receive a blade and provides a cutting surface to hold the material, wood, steel, etc., which is to be cut. Significant to the invention is a central frame which attaches to the vehicle frame, preferably the tailgate of a vehicle. The attachment in the preferred embodiment is a magnetic bar which is useful on any tailgate as discussed in more detail below. This bar may be a non-magnetic bar bearing a magnetic strip located at the base of the tailgate. This magnetic strip or bar may also be removable for cleaning, etc.
The tool would typically be one which has a blade of some type which extends out of an opening defined by the central frame. The top of the central frame supports the item to be cut. The tool may either be suspended over the material and central frame opening or it may extend up from the bottom of the central frame into the opening. The blade may be movable within the central frame opening.
Examples of tools would be saws having saw blades, welders having welding tips, torches having torch valves (the flame being the blade); lasers having beams, drill having bits and the like. A drill held above the central frame opening so that the bits goes into the frame opening would be a predictable tool given the disclosure set out herein as would a saw moving on an arm over the opening in the central frame.
It can be seen, therefore, that while a saw and saw blade are discussed herein, blade refers to any type of blade, bit, torch, or the like attached not only to a saw but to a saw, a drill, or any type of cutting or welding device.
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.
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.
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.
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.
It is further the object of this invention to provide a sturdy, stable surface for cutting in a variety of environments.
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.
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.
