Goalpost upright verticality adjustment system and method
Rotatable sleeves are disposed adjacent the ends of the crossbar of a goalpost. A stub is integrally formed with each of the sleeves and each stub protrudes through an opening in the crossbar. The opening in the crossbar is dimensioned to permit back to front movement of the stub and corresponding rotation of the sleeve until verticality of the stub and its associated upright is achieved. At that point, the sleeve is locked against further rotation by means of a tapping block previously installed in the sleeve and engaged with a serrated bolt through an appropriately dimensioned opening in the crossbar and corresponding holes in the sleeve. Once the bolts are tightened into the tapping block, the sleeve is drawn tightly against the interior surface of the crossbar, thereby locking the sleeve and the stub and the upright against further rotation.
1. A method of making a system for supporting and adjusting the verticality of an upright of a sports goalpost, the method comprising:
providing a crossbar having a wall around a central axis and having at least one opening in the wall near an end of said wall;
inserting a rotational member into the crossbar at the location of the opening;
passing a stub through the opening in the wall of the crossbar and rigidly attaching it to the rotational member, said opening being dimensioned to permit a preselected amount of rotational movement of the stub and rotational member about the axis of the crossbar; and
providing a lock for selectively preventing rotational movement between the rotational member and stub on the one hand and the crossbar on the other.
2. The method of claim 1 wherein the rotational member is a sleeve.
3. The method of claim 1 wherein the rotational member is provided with at least one cutout and wherein the stub attaching step includes the step of inserting the stub through the crossbar opening and through the rotational member cutout.
4. The method of claim 3 wherein the lock is comprised of a tap block affixed to the sleeve and a bolt insertable into the tap block through the crossbar and the sleeve into the tap block.
