1. A bogey assembly including a body with a bore for threaded engagement with a hanger bolt, and a lock mechanism to engage side flats of the hanger bolt and thereby lock the bolt against rotation and axial movement relative to the body, wherein the lock mechanism includes a collar arranged to fit onto the side flats of the bolt and rotate with the bolt during height adjustment obtained by rotating the bolt relative to the body, and wherein the lock mechanism further includes a keeper that is arranged to move from a free position into an engaged position with the collar, in order to lock the bolt against rotation relative to the body.
2. The bogey assembly of claim 1 , wherein the collar has a throat adapted to key with the side flats of the hanger bolt, and a slotted profile into which the keeper is moved to engage and lock the collar against rotation.
3. The bogey assembly of claim 1 , wherein the keeper is retained in the engaged position under bias.
4. The bogey assembly of claim 1 , wherein the lock mechanism includes an actuator button to move the keeper between the free position and the engaged position.
5. The bogey assembly of claim 4 , wherein the lock mechanism has a cover plate to capture the keeper in the body, and the button projects through the cover plate.
6. The bogey assembly of claim 1 , wherein at least part of the lock mechanism is recessed into the body.
7. The bogey assembly of claim 1 , including a hanger bolt with a thread to engage in the bore of the body and with side flats that are engaged by the collar of the lock mechanism to secure the bolt against rotation.
