ABSTRACT:
A tomato cage is provided which can be quickly and easily assembled with no tools at all, or merely a pair of pliers. When disassembled it can be stored in a minimum space, and since there are very few different components, it can be manufactured in a simple manner. A plurality of vertical support posts are disposed at the corners of a polygon; e.g. four support posts are disposed at the corners of a square. Rods interconnect the support posts, apertures being formed in the support posts for receiving a first end of a rod. Only one type of rod need be utilized, having a generally straight first end and having a hook at a second end, each rod extending from an aperture in one post to a position wherein the hook engages another rod adjacent the second post, and so that each rod makes an angle in the range of about 5.degree.-10.degree. with respect to the horizontal. Alternatively, a second type of rod may be provided having a first end like the first ends of the first rods, and having a second end comprising a straight portion generally perpendicular to a straight middle portion of the rod. In this embodiment three first rods and a second rod are provided for each level, with a middle portion of one rod extending through an opening in a keeper washer and the second end of the second rod also extending through the opening in the keeper washer and held in place thereby. Preferably one of the four support posts is driven into the ground up to an indicia line, while the other three, being the same length, rest on the ground.
