ABSTRACT:
A wall toggle apparatus (10) for securing a threaded fastening member (18) to a wallboard wall (16) including a saw member (12) having an annular body (20). The body has a central passage (22) extending the length of the saw member and interrupted by a threaded external portion (38) having a slot (40) adapted for receiving the threads of the fastening member. The saw member further includes opposed openings (32) extending through the walls of the body. The leading end of the saw member further includes a plurality of teeth (30) for sawing through the wallboard wall. The wall toggle (10) further includes a toggle member (14) which includes a ratchet portion (54) adapted to receive the threads of the fastening member. The toggle member further includes a central hole (60). In operation the saw member is rotated against the face of a wallboard wall sawing into the wall and creating a hole therein. The saw member is further rotated to secure the saw member therein. Once the saw member is secured in the wall the toggle member is inserted into the passage of the saw member and maneuvered to extend between the openings. The fastening member is then inserted into the passage of the saw member and rotated to engage both the slot (40) and the hole (60). Rotation of the fastening member draws the fastening member into the saw member and draws the toggle member into engagement with the back side of the wallboard.
