  • Patent number: 9512638
    Abstract: A lock cylinder generally including a shell, a plug positioned within the shell, a locking member, and a leaf spring. The plug includes an opening which is aligned with a recess formed in the shell. The locking member is configured to selectively prevent rotation of the plug with respect to the shell. The leaf spring is positioned in the opening and includes a first portion extending radially inward toward the keyway, and a second portion extending radially outward toward the recess. When a key is inserted, a tip of the second portion extends into the recess. When the plug is subsequently rotated, a tapered surface of the recess urges the tip radially inward and into contact with an inner surface of the shell.

  • Publication number: 20140007632
    Abstract: The present invention, and inventive system, is a new locking mechanism that prevents entry for doors, or other barriers that can use a deadbolt system, or system comparable to a deadbolt system. The present invention can be installed and works in corn unction with the existing deadbolt assembly to prevent lock, picking, a bump key, or a user's own key from being used to open the door. In the present invention, by engaging the arm latch, or arm actuator, of the present invention, over the turn knob on an existing deadbolt, the present invention prevents the free rotation movement of the turn knob, thus not allowing retraction of the deadbolt, and entry through that door or barrier.

    Abstract: A transport clip for attachment to a key fob is provided. The transport clip includes a neck at least partially surrounding a key blade, which is selectively rotatable between a stowed position in which the key blade is substantially within a fob body and a deployed position in which the key blade extends away from the fob body. The neck prevents rotation of the transport clip relative to the key blade. The transport clip also includes an ear portion that depresses a latch button to an unlocked position, which allows substantially free rotation of the key blade, relative to the fob body, between the deployed position and the stowed position.

  • Patent number: 4328693
    Abstract: The present invention relates to an electrically actuated lock of the type comprising a rotor pivoting in a body and capable of being locked in relation to the said body by locking members constituted by pairs of opposed pistons or by keepers. The locking members are displaced by notches of a key, coded to permit the rotation of the rotor by action upon the key head. In this invention the unlocking of the rotor is effected by electric means without any opening of the rotor to the external environment, thus ensuring perfect sealing and inviolability. The lock comprises a key shank provided with coded notches, the shank being connected in translation with the movable armature of an electro-magnet, the rotor being provided with a graspable head by means of which the user can rotate the rotor when unlocked by the key.
