Accordingly, when a bow, such as the bow 30, FIG. 1, is mounted with its limbs 34 a and 34 b extending between the tines 27 b of the respective bracket support members 27, the brackets 24 are biased to rotate to forcibly but releasably engage the bow limbs and retain the bow 30 supported therebetween, preferably in a standoff position from the base parts 27 a of each of the brackets.
