  • Patent number: 11053968
    Abstract: A blind bolt and tool is used for fastening a bolt through a hole in a structure when only one side of the structure is accessible. A receiver is formed on the tip end of a bolt shaft opposite from a bolt head. Internal threads are formed within the receiver proximate an outward end, and a hex socket is formed in the inward end of the receiver. External threads and a guide are formed on a tip of the tool, and the external threads mate with the internal threads in the receiver to hold the bolt during installation. A hex key on one end of the tool engages the hex socket in the receiver so that the tool may impose a torque on the bolt when a nut is being tightened on the bolt. In another embodiment, a splined tip is formed on the end of the bolt. The tip is designed to shear off when a sufficient torque is applied. Also, a shim is configured to fit between structures held together by the blind bolt.

    Abstract: An anchor assembly for walls comprises a toggle member and a strap member pivotally mounted together, and a locking member. In a first position, the toggle member is aligned with the strap member for insertion through a hole in the wall, whereas in a second position, the toggle member extends behind the wall angularly to the strap member which extends from the toggle member through the hole. The locking member is adapted to be displaced along the strap member until it engages the wall and to be locked on the strap member to prevent the locking member from displacing away from the toggle member. Therefore, the locking member and the toggle member are connected by the strap member and imprison the wall by abutting respectively the visible and hidden sides thereof. A fastener introduced through the locking member and the wall threadably engages an opening defined in the toggle member.

  • Patent number: 8491246
    Abstract: An exemplary securing structure includes a base, a fastener, and a spring mounted around the fastener. The base defines a through hole, and two slots located adjacent to and communicating with the securing hole. Two barriers are formed at a bottom of the base corresponding to the slots. A gap is defined between the bottom surface and each of the barriers. The fastener includes a head, a bolt, and two blocks extending outwardly from a periphery of the bolt corresponding to the slots, respectively. When the bolt is extended through the securing hole with the blocks extending through the slots until the blocks are received in the gaps, the fastener is then rotatable to cause the block to escape from the gap and abut on the bottom surface of the base, with the spring resiliently compressed between the head of the fastener and a top side of the base.
