Patent number: 9004552Abstract: A heavy vehicle door or ramp is opened and closed using an intuitive control system. The door includes a latch assembly, a lock assembly, and a power unit to assist in opening and closing the door. The door includes an interior joy stick handle and an exterior lever handle. From outside the vehicle, the door is opened and closed by pivoting the lever handle downwardly and upwardly, respectively. From the interior of the vehicle, the joy stick handle is pulled inwardly to close the door and pushed outwardly to open the door. Pivoting the joystick handle forwardly engages the blast locks, while pivoting the joystick handle rearwardly unlatches the latch assembly and disengages the blast locks. The power assist unit is actuated by pivotal movement of the outside door handle and lateral pivotal movement of the interior joystick handle.Type: GrantFiled: March 6, 2012Date of Patent: April 14, 2015Assignee: Trimark CorporationInventors: Tom F.

Patent number: 8998275Abstract: 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.Type: GrantFiled: April 24, 2008Date of Patent: April 7, 2015Assignee: Trimark CorporationInventors: Robert W.

Patent number: 8091933Abstract: A heavy duty vehicle door latch assembly is provided with interconnected latch, release, and bell crank modules to form a single, pre-assembled unit for quick and easy installation on the inside of a vehicle door. The modular design allows for application to multiple door layouts and arrangements. The release module includes a locking mechanism using a lever rod to disallow latch component movement. A release lever interfaces with the lock lever to automatically unlock and release the latch in a single motion. A lockout feature is also provided to prevent accidental locking of the door.Type: GrantFiled: September 21, 2007Date of Patent: January 10, 2012Assignee: Trimark CorporationInventors: Brandon L.

Patent number: 6189949Abstract: A sun visor is disclosed having a body with an aperture through which an extender blade selectively slides between fully retracted and fully extended positions. The visor body is a clamshell type having first and second shell halves. A guide rib is located on one shell half to align and guide the extender blade as it moves into and out of the visor body. The aperture is formed by a recessed portion in at least one of the shell halves. Fabric covers the visor body and also extends into the aperture and covers at least part of the guide rib.Type: GrantFiled: December 3, 1998Date of Patent: February 20, 2001Assignee: Lear Donnelly Overhead Systems L.L.C.Inventors: Douglas C.

Patent number: 4835517Abstract: A modem which may operate as a transmitter or receiver, is provided for use on a line carrying an A.C. signal. The modem comprises a pseudorandom code generator which produces a pseudorandom code signal of a frequency an integral multiple of the A.C. signal frequency. Synchronization means synchronizes the code signal with the A.C. signal. Preferably a coherent system is provided in which a data signal involved has a bit rate an integral multiple of the A.C. signal frequency and in which a carrier generator is additionally provided to produce a carrier signal of a frequency an integral multiple of the A.C. signal frequency. In such case, the synchronization means also synchronizes the data bit and carrier signals with the A.C. signal.Type: GrantFiled: June 20, 1984Date of Patent: May 30, 1989Assignee: The University of British ColumbiaInventors: Peter K. van der Gracht, Robert W.
