  • Patent number: 11873669
    Abstract: A latching system includes a guide body, and a latch rod slidably retained by the guide body. Latch assemblies fixed to the latch rod, are spaced apart from one another, and independently biased to a latched position. A first rod-biasing spring is coaxial with the latch rod and disposed between the guide body and a first latch assembly. The first rod-biasing spring biases the latch rod to a rest position corresponding with a latched position of the latch assemblies. Multiple catches are secured at a spacing equal to a spacing of the latch assemblies on the latch rod such that the latch assemblies latch to the catches independently of one another. A force on the latch rod against the first rod-biasing spring moves the latch rod along the longitudinal axis of the latch rod from a rest position to an actuated position and unlatches the latch assemblies simultaneously.

  • Patent number: 8998275
    Abstract: An assembly is provided for opening a heavy weight door, such as on a military vehicle, by an occupant in the vehicle. The assembly includes a latch module with a catch and rotor adapted to engage and disengage the striker on the door frame, a blast lock module including a pawl adapted to engage and disengage the door frame, and a release handle module with a single interior handle for controlling the engagement and disengagement of the latch and blast lock modules. The three modules are pre-assembled on a carrier plate so as to form a rigid, unitary assembly for mounting on the inside of the door. When a person chooses to exit the vehicle, the handle is actuated so as to retract the blast lock and then release the latch. When the door is closed, a person inside the vehicle can actuate the handle so as to engage the blast lock for safety.

  • Patent number: 7784841
    Abstract: A vehicle has a door release apparatus for a first door supporting a door latch for a second door. A first door latch connects the first door with respect to a frame defining a vehicle body opening. A handle member has at least an inboard portion and is mounted to the first door for movement about an axis. A force transmission assembly is operably engaged between the handle member and the first door latch for movement between a latch-engaged position and a latch-released position. A door release lock-out is defined by a portion of the second door directly obstructing movement of the handle member, when the second door is in the at least partially latched position. The door release lock-out prevents movement of the handle member a sufficient distance to release the first door latch from the frame when the second door is in the at least partially latched position.
