Abstract: A locking assembly for a door assembly of an agricultural vehicle includes: an actuator that defines an actuator axis and is linearly movable between a first position and a second position and rotatable about the actuator axis between a first locking orientation and a second locking orientation and includes a pair of locking features; a biaser configured to bias the actuator toward the first position; an energizer configured to bias the actuator toward the first locking orientation when the actuator is in the second locking orientation; and a lock configured to engage a second locking feature when the actuator is in the second locking orientation. Linear movement of the actuator from the first position to the second position while the actuator is in the second locking orientation causes the lock to disengage from the second locking feature so the energizer rotates the actuator towards the first locking orientation.

Abstract: A ratchet wrench (10) includes a unitary socket assembly (20) having a collet (26) and an adjustable fastener engaging socket (24) which may be positioned over a conventional fastener and which may then be decreased in diameter to effect a gripping attachment of a fastener. The socket assembly (20) includes a stud (28) that is releasably engageable with the ratchet wrench (10). A locking lever (80, 80A) is attached to the ratchet wrench (10) and is usable both to decrease the diameter of the socket (24) and to releasably lock the socket in attachment with the fastener. The locking lever (80, 80A) may employ ratchet and pawl members (400, 402). If desired, the ratchet wrench (10) may instead be pneumatically activatable. Further, the wrench (10) also includes a camming means for reducing the diameter of the adjustable fastener engaging socket (24) formed on the inside of the leading edge of the collet (26), and on the outside edge of the socket.

Abstract: A ratchet wrench includes an expandible fastener engaging socket which may be positioned over a conventional fastener and which may then be decreased in diameter to effect a gripping attachment. A locking lever is attached to the ratchet wrench and is usable to both decrease the diameter of the expandable socket and to lock the socket in attachment with the fastener. The lever operates in the manner of a conventional lockable plier so as to provide the ratchet socket wrench with a plier-like function.
