The modular construction of the lock and latch system of the present invention can include the outside and inside door handles, the outside and inside locks, the door latch itself, as well as linkages between these components. The modular components of the present invention can further facilitate the assembly process by being of a design which simplifies the process of installing them into the structural framework of a vehicle door without requiring the use of specialized tools, thereby reducing the labor costs associated with assembly.

Abstract: In some embodiments, lock assemblies are disclosed which have a housing, a barrel, and at least one tumbler. In some cases, the lock is codeable after the lock assembly has been assembled. Although not required, some embodiments can be re-coded to a new code with and without disassembling the lock assembly. The tumbler(s) can be pivotable, while in other embodiments the tumbler(s) move in a substantially linear fashion. The tumbler(s) can be comprised of two pieces or portions, wherein one piece/portion of the tumbler(s) either directly or indirectly engages the coded surface of a key while the other piece/portion is positionable to prevent rotation of the barrel with respect to the housing. In some embodiments, the tumblers are external to the barrel.

Abstract: In some preferred embodiments of the present invention, a fastener on a door handle assembly having a door handle is moved by actuation of the door handle into a position in which the fastener connects the door handle assembly to the door. The door handle is preferably capable of transmitting door handle actuation force to the fastener to move the fastener. In one preferred embodiment, this force is transmitted by camming action against a sliding member to which the fastener is connected. In another embodiment, this force is transmitted by pulling a sliding member with links connected to the handle. The movable fastener can connect with a second fastener connected to the door handle assembly or to the door. Therefore, when the movable fastener is moved by actuation of the handle, the movable fastener can connect with the second fastener to secure the door handle assembly to the door.

Abstract: The present invention includes a pawl releasably engagable with a ratchet, a handle connected directly or indirectly to a user-manipulatable device, a cam movable between an unlocked position in which actuation of the cam by the handle generates sufficient pawl movement to release the ratchet and a locked position in which actuation of the cam by the handle does not generate sufficient pawl movement to release the ratchet, and a lock coupled to the cam for moving the cam between its unlocked and locked positions. The cam has at least one cam surface that, when the cam is moved by the lock toward its unlocked position, cams against one or more surfaces of the pawl, the handle, or the pawl and the handle if the handle is already partially or fully actuated. In some highly preferred embodiments, the cam is movable within an aperture in the pawl, an aperture in the handle, or apertures in the pawl and handle.

Abstract: Highly preferred embodiments of the present invention have a lock bolt extendible and retractable by movement of a power transmission assembly driven by an actuator and having a cam thereon which cams against the lock bolt to retract the lock bolt and unlock the steering column. In some preferred embodiments, the cam has a curved surface with varying distance from the axis of rotation of the cam or pivot to produce smooth and controlled lock bolt camming action with little to no jarring motion. In order to significantly reduce manufacturing and assembly time and cost, some or all of the power transmission assembly can be assembled prior to installation in the lock assembly frame. More preferably, some or all of the power transmission assembly is integrally formed. Preferably, part or all of the lock assembly can be assembled without turning, flipping, or otherwise re-orienting the lock assembly during assembly.

The latch assembly further includes a ratchet arranged and configured for rotation with the control element when the control element is engaged by the actuator and for non-rotation when the control element is disengaged by the actuator. A highly preferred embodiment of the invention includes an automatic unlocking circuit powered by a backup power source.

Abstract: A door assembly for a motor vehicle comprises a molded door panel having a first side and a second side. The first side of the door panel is adapted to face towards a passenger compartment of the motor vehicle. The second side of the door panel supports a belt line reinforcement, a lock and catch assembly, and a window lift assembly. The door assembly is adapted for joining with a door exterior.

Abstract: An improved modular vehicle door lock and latch system is disclosed which includes a door latch mechanism, an inside door latch and door lock handle, and a unique outside door handle and door lock interface member, all of which are assembled into a pre-connected configuration together with all necessary control cables, thereby significantly reducing the labor required to assemble the lock and latch system into a door of a motor vehicle and correspondingly resulting in a significant cost reduction. A first module includes the inside door handle, the outside and inside locks, the door latch, and an outside door lock and door handle interface member, as well as linkages between these components. A second component is an outside door handle assembly which will be operatively connected to the outside door lock and door handle interface member.

Abstract: A free-wheeling lock assembly includes a case and a drive mechanism which is adapted for coupling to a latching mechanism. The drive mechanism includes a lock barrel supported within the case for rotational and axial movement relative to the case and a driver releasably coupled to the lock barrel but fixed against axial movement. The drive mechanism further includes first and second slidebars supported within the case for axial movement relative to the case. The slidebars are coupled to the lock barrel by tumblers of the lock assembly, and translate the lock barrel axially with respect to the driver, decoupling the driver from the lock barrel in response to rotation of the lock barrel when the tumblers are in a locking position. However, the tumblers permit relative axial movement between the first and second slidebars and the lock barrel when the tumblers are in a releasing position, permitting the lock barrel to rotate the driver for operating the latching mechanism.

Abstract: In some preferred embodiments of the present invention, a fastener on a door handle assembly having a door handle is moved by actuation of the door handle into a position in which the fastener connects the door handle assembly to the door. The door handle is preferably capable of transmitting door handle actuation force to the fastener to move the fastener. In one preferred embodiment, this force is transmitted by camming action against a sliding member to which the fastener is connected. In another embodiment, this force is transmitted by pulling a sliding member with links connected to the handle. The movable fastener can connect with a second fastener connected to the door handle assembly or to the door. Therefore, when the movable fastener is moved by actuation of the handle, the movable fastener can connect with the second fastener to secure the door handle assembly to the door.

Abstract: A dual cam, reversible key includes first and second patterns of notches in first and second edges of the shank of the key on a common side of the key shank of the key, providing a dual cam key. The patterns of notches are formed to have complementary symmetry and to make the width of the shank constant along at least the portion of the shank that includes the notches. The first pattern of notches is identical with the second pattern of notches insomuch as they are "parallels" to each other. The key operates tumblers each of which has an opening defining a pair of staggered generally rectangular windows, each of the windows defining cam surfaces for accommodating the dual cam, reversible key. Also disclosed is a method for making the dual cam, reversible key.

Abstract: A free-wheeling lock assembly includes a free-wheeling lock mechanism which prevents damaging forces from being applied to the components of the lock assembly if the lock cylinder is forcibly rotated by a key other than the proper key or by some other instrument. A detent mechanism, which functions independent of spring bias, couples the sleeve to the case in the presence of the proper key in the keyway. A clutch mechanism couples the cylinder to the driver, but decouples the driver from the cylinder for an over-torque condition. The cylinder lock assembly further includes a locking mechanism which prevents operation of the latching mechanism of the lock assembly if the cylinder is slam-pulled from the case. The tumblers are isolated from rotary motion of the tumbler ward.
