Abstract:
1. A mobile sheet material handling cart comprising a lower frame and an upper frame with a height adjustment mechanism between the lower and upper frames; wherein said lower frame is comprised of a X shaped frame having four metal legs forming said X shape, further having caster wheels located at the outer ends of each of the four legs; a baseplate attached at the center of the lower frame, said baseplate has a post welded thereto and said post projects in a direction opposite the caster wheels; said post forms a first part of the height adjustment mechanism; and the lower frame has two table stops attached to two of the four metal legs; wherein said upper frame is comprised of a rectangular table frame having four sides, a top side, and a bottom side; a first side of the four sides having a material support channel attached along its entire length and projecting perpendicularly from the top side of the table frame, second and third sides of the four sides are perpendicular to the first side, and each of the second and third sides having one of two pivot collars attached thereto; wherein a T-post assembly is rotatably held inside said two pivot collars at its two outermost ends, so as to allow the table frame to rotate relative to the lower frame from a horizontal position to a near vertical position; the T-post forms a second part of the height adjustment mechanism; the vertical portion of the T-post slides over the post that is attached to the lower frame, and adjustment of the height is controlled by tightening and loosening a knob and bolt assembly that clamps the T-post and the post together; wherein the two table stops keep the table frame from rotating too far when moving the table frame from the horizontal position to the near vertical position; wherein the cart has a tilt control assembly that is comprised of two latches and a support bar that locks the table frame in either of the horizontal or vertical positions; and wherein the cart has a material clamp; said material clamp comprising a rod, a jaw, and a tightening knob that allows the material clamp to rotate and slide over the material, said knob is tightened and the material is securely clamped between the clamp jaw and the material channel.
