Abstract
The disclosure relates to a spreader mechanism for supporting the legs ( ) of a tripod erect, comprising a hub ( ) having a central axis, three arms ( ) pivotally mounted on the hub at positions equi-spaced around the hub to swing with respect to the hub axis between extended and folded positions. A drive mechanism ( ) coordinates movement of the arms so that all three arms remain in the same relationship to the hub axis throughout the range of movement of the arms, and a locking device ( ) locks the drive mechanism against movement at any position throughout the range of movement of the arms. The locking device may be released held by a push button operated mechanism ( ) to allow adjustment of the spreader member and the holding means is deactivated to allow engagement of the locking device to lock the arms in a selected position of adjustment.
