AbstractThe improved anchoring bolt device of the present invention is adapted to be inserted through an opening in a partition to anchor fixtures, etc., thereto. The device includes a bolt having an elongated shaft adapted to extend through the opening and bearing on its front end one or more arms pivotally connected thereto through a flexible neck and urged from a collapsed position which enables them to pass through the opening to an operative normally unfolded position behind the wall so as to anchor the device in place in the wall. In one embodiment the neck is of uniform diameter and is elongated and curved in an arc extending generally transversely of the device. The rear end of the shaft may have a loop or other means for pulling the shaft back to prevent its loss in the wall. A collet is releasably secured as by threading or ratcheting, over the shaft to hold a fixture to the outside of the wall. The shaft may be frangible to adjust its length and a rear cap may be provided. Spikes may project from the front face of the collet and rear faces of the arms to anchor them in place. The arms are in one plane and are preferably long and narrow to facilitate installation of the bolt next to a stud or header or base plate. Preferably, all components are of very inexpensive, durable resilient plastic.
