The invention concerns a locking mechanism provided and adapted to interact with at least one locking element to establish a locking between the locking mechanism and the locking element, wherein the locking mechanism comprises a first locking pawl and a second locking pawl which are rotatable independently of each other about a first rotary axis, wherein the first locking pawl is provided and adapted to interact with a first locking element and wherein the second locking pawl is provided and adapted to interact with a second locking element, wherein a secured locking is present when the first locking element is locked to the first locking pawl and the second locking element is locked to the second locking pawl.

A latch mechanism is used with agricultural equipment, such as a mower, for securing the header of the mower to the tongue during transport. A pivoting catch is mounted on the trail frame on which the header is mounted. A receiver for the catch is mounted on the tongue. During mower transport the catch is biased into engagement with the receiver by a first spring and secures the header to the tongue in a parallel orientation. When the mower configuration is changed to operational mode the catch is disengaged from the receiver using a second spring attached to the catch. A cable attaches the second spring to a wheel arm of a field wheel. Deployment of the field wheel into the operation mode draws the cable and second spring into tension, overcoming the biasing force of the first spring and pivoting the catch out of engagement with the receiver.

An aircraft door latch apparatus having a latched configuration and an unlatched configuration can include a door structure of an aircraft door assembly, a handle coupled to the door structure and pivotably moveable with respect to the door structure between a latched position and an unlatched position, the handle including at least a first wall and a handle cavity, and a latch apparatus coupled to the handle. The latch apparatus may be operable to move the handle between the latched position and the unlatched position, the latch apparatus received in the handle cavity and arranged to be concealed by the handle when the aircraft door latch apparatus is in the latched configuration and the unlatched configuration. Related methods are also provided.

A handle is arranged for controlling the latch to engage or disengage the keeper. The handle is positioned in a recess of the removable electronic device. A panel or cover covers the handle. The cover has one or more retainers associated with a first end. An opening is associated with a second end opposite the first end. A rotatable lock is secured in the opening, where in a locked state the rotatable lock has a lock latch that engages a lock recess or lock keep in the recess to secure the panel to prevent access to the handle.

A wirelessly controlled door stop is disclosed. In particular, the door stop can include a body portion and a rotatable stop along with a microprocessor and a wireless transceiver. When proper authorization is received the microprocessor activates the rotatable stop, which then rotates from within the body portion to a deployed position that will prevent access to a doorway in which the door stop has been installed. Additionally, the access to the door stop can be logged by a cloud system, which can be accessed by the door stop by the Internet.

A device for securing a door including a rotatable handle affixed to the door, a rotatable member affixed to the door, a catch, and a protrusion from the rotatable handle that is configured to lift the member when the member is engaged with the catch and the rotatable handle is rotated.

A device for securing a door including a member configured to be rotatably attached to the door, a catch configured to be attached to a wall adjacent to the door and to receive the member, and a protrusion configured to be attached to a handle on the door and to lift the member when the member is in a closed position and the handle is rotated.

A method for installing a device for securing a door with a handle, the method including affixing a member to the door so that the member can rotate, affixing a catch to a wall adjacent the door, the catch configured to receive the member, and affixing a protrusion to the handle, the protrusion configured to lift the member when the member is engaged with the catch and the handle is rotated.

Systems for latching and locking an aircraft door and associated methods are disclosed. The system comprises a latch and a lock. The latch can be configurable between: a latched configuration where the latch interferes with a lift mechanism for causing lifting of the aircraft door to permit opening of the aircraft door; and an unlatched configuration where the lift mechanism is permitted to cause lifting of the aircraft door. The lock can be configurable between: a locked configuration where a configuration change of the latch from the latched configuration to the unlatched configuration is prevented; and an unlocked configuration where the configuration change of the latch from the latched configuration to the unlatched configuration is permitted.
