Abstract
An all-metal grape stake is provided that includes an elongated metal upright member which is rolled to have a V-shaped cross-section with flanges extending along its two edges. The grape stake also includes a cross-arm in the form of a metal strip which extends across the upper end of the upright member and which has a bent-over upper edge extending across the top of the upright member. A V-shaped bracket is mounted in the center of the cross-arm, and this bracket receives the upper end of the upright member. In assembling the grape stake of the invention, the upright member is first driven into the ground, and the cross-arm is dropped over the upper end of the upright member until its upper edge engages the top of the upright member, with the upper end of the upright member being received in the bracket. The cross-arm is then turned about the horizontal axis of the upright member until one flange of the upright member engages the apex of the bracket and the other flange snaps into slots in the cross-arm, so that the cross-arm is firmly held on the upper end of the upright member.
