Extendible bunk stake

An extendible bunk stake for a log truck and the like, comprising

• an upright post adapted to be mounted on the truck for confining a log load thereon,
• an elongate extension member slidably mounted on said post for axial shifting thereon between a lowered position and a raised position where said member functions to extend the height of the stake,
• latch means on said post for locking said member releasably in its raised position,
• an arm mounted on said member, at the upper end thereof, for shifting between an upwardly projecting position and an inwardly projecting position where the arm is adapted to be engaged by a log being raised adjacent the side of the stake facing the truck, to raise the stake from its lowered toward its raised position, and
• locking means interposed between said extension member and said arm adapted for holding the latter releasably at its inwardly projecting position, as the extension member is being raised by a log engaging the arm, and for releasing such arm for movement toward its upwardly projecting position upon continued upward movement of such a log beyond the point where said extension member has reached its raised position.
