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. The present invention relates to 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 which allows for a saw table supported in place of or as an attachment to the bed or tailgate of the truck. The invention also allows for the incorporation of two spaced sawhorses. The prior art does not suggest a saw horse which can fit over the raised sides of a tailgate or rear panel of a flat bed truck. The saw horses provide a bracket for holding the cutting surface so that the exposed ends are held parallel for cutting.
A saw horse cutting surface is a surface which comprises at least two lengths of 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 by providing a holder for a cutting surface, and in particular parallel cutting surfaces so that they may be used in the same manner as a conventional saw horse mounted on a tailgate.
The present invention provides a transportable saw horse, which may be attached to a vehicle, 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 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 described herein is a device for holding a cuttable item to be worked on and for mounting a tool having a blade. The cuttable item is supported by the attached device attached to a vehicle resting on the ground. The vehicle has a vehicle frame having a left panel and right panel with a top and bottom. The device has a central frame having a left side and right side, a top and a bottom, an inside and outside defining a central framing opening. The central frame defines a frame surface for holding material and the central frame further defines a tool holding means for holding the tool. The tool holding means may hold a saw, a drill press, a jig saw or other similar tool.
Preferably, where a saw blade is held to work on the item to be cut, the saw blade can be angled in any direction by having it rotationally mounted or by having it mounted so it can tilt. In addition to a saw blade it may have built in or added clamps to hold wood being worked on in place.
The central frame is rotationally attached at the left side and right side to the vehicle. For a truck, this would be in place of the tailgate (when the central frame is raised) between the left panel and right panel so it may be lowered with the outside facing the ground (when lowered to be used as a saw table).
The central frame is rotationally attached to the bottom of the left panel and the bottom of the right panel so it can rotate down.
Since the ground is uneven, the central frame may have an angle means for adjusting the angle at which the face surface is suspended above the ground. A part of this angle means may be the vehicle bumper below the left and right panels so that the bumper supports the central frame when it is rotated downward. Adjusted pads under the left and right side of the frame may serve to balance the sides. Legs with adjustable length may also be used.
Typically, the saw or other device has a motor and the central frame comprises a holding means for holding the motor on outside. In this way the motor of a saw is below the central frame when the blade is held above the cutting surface defined by the top of the central frame. The central frame defines a blade opening for allowing the blade of the tool to extend through the central frame to cut an object held on the frame surface.
For several purposes which will become clear, the central frame comprises a first portion attached to the surface of the vehicle, and at least one second portion extendably attached to the first portion so that the length of the frame surface may be extended. One reason is to allow the table to be longer than a normal tailgate, but retractable to be the same size as a tailgate.
There may be a locking means for fixing the position of the first portion relative to the at least one second portion. The first portion preferably defines slots and the at least one second portion defines beams which are extendable from within the first portion slots.
The second portion may, alternatively, be foldably attached to the first portion by way of pivots so that the second portion may fold out at the pivots from the first portion.
Since most tailgates are removable, the device is approximately the same size as the replaceable panel replaced when the beams are not extended.
The invention preferably comprises at least one third portion extendably attached to the at least one second portion. This may have a flat bar raised above the cutting surface to guide a straight edge of the article to be cut into proper position with the cutting blade. The central frame may also have a first measuring means for determining the distance between this flat bar and the blade of the tool used to cut the article to be cut. The central frame may hold the cuttable article square to the blade. It may also articulate to hold the article at a predetermined angle to the blade if the blade is fixed in place.
The first measuring means is preferably a ruled means showing the distance between the part and the blade to be cut. At least one alignment bar sizeably connected to the frame surface and a ruled scale between the alignment bar and the blade is preferable.
The alignment means may have a second alignment bar con
