The moveable structure may be an aircraft cowling and the keeper may be mounted to an aircraft structure. The double jaw latch includes a handle rotatably mounted to a housing. The handle has an open position, a closed position, and a pre-catch position. The handle is connected to a double jaw assembly which likewise has an open position, a closed position, and a pre-catch position. The double jaw assembly includes a first jaw and a second jaw mounted in pivoted relation for movement to and from each other to engage the keeper. When the double jaw latch is in the open position, the jaws are spaced apart to permit disengagement with the keeper. In the closed position, the jaws are trapped within the housing and rigidly retain the keeper.Type: GrantFiled: August 11, 1998Date of Patent: March 28, 2000Assignee: Hartwell CorporationInventor: Frank Thomas Jackson

Patent number: 5906403Abstract: A multipoint lock for securing a door to a door frame includes a tie bar longitudinally movable on the door with two latch members adjustably secured laterally relative thereto. The latch members are modular with hooks for selectively securing to the tie bar and other latch members. A metal face plate is securable over a door side groove with the tie bar movably secured to the plate in the groove at at least two locations by securing members extending through openings in the plate, tie bar and a plastic spacer. The securing members each include a longitudinal body member with parallel longitudinal sides cooperating with a tie bar slot to guide the tie bar. Rivets at ends of the securing members are secured to the plate. A link, pivotable about a substantially horizontal axis, has one arm driveably engaging the tie bar to selectively move the tie bar vertically toward a disengaged position.Type: GrantFiled: May 12, 1997Date of Patent: May 25, 1999Assignee: Truth Hardware CorporationInventors: William J.

Patent number: 5741031Abstract: A window lock actuator including a link assembly rotatably mounted on the window jamb, the link assembly operably securable to control movement of a cam into and out of engagement with a keeper for locking a sash to a window jamb. A handle is detachably secured to the link assembly for rotation therewith, and has two legs cradling the link assembly when the handle is secured thereto. Two tabs on the link assembly and two recesses on opposite inner surfaces of the legs engage when the handle is secured to the link assembly. An escutcheon has a spring secured on one side, which spring is biased outwardly against one side of a jamb cavity to frictionally secure the escutcheon in the cavity.Type: GrantFiled: March 18, 1996Date of Patent: April 21, 1998Assignee: Truth Hardware CorporationInventors: Leonard P. Bauman, Eric P. Heim, Peter E. Braun, Joseph P. Landherr

Patent number: 5738393Abstract: An automotive hood latch includes a striker carried by the hood latch and two separate latching members carried by the vehicle for alternate engagement with the striker, one of the latching members serving as a safety. The separate latching members are sequentially operated in the unlatching direction by double reciprocation of a remote cable operator. The motorist can release the hood from both latching members without leaving the vehicle.Type: GrantFiled: November 8, 1996Date of Patent: April 14, 1998Assignee: Ford Global Technologies, Inc.Inventor: Yi J.

Patent number: 5722704Abstract: A door lock has a latch which is rotatable from a retracted position to an extended position by means of a linkage. A safety button extends from the latch when the latch is retracted. The linkage cannot be moved unless the safety button has been pressed, which occurs when the door is adjacent the door frame. This prevents the latch from extending and so damaging the keeper in the door frame. The linkage also has a notch which cooperates with a tang projecting from the housing. The tang an notch prevent the latch from being rotated from the extended position to the retracted position except by operation of the linkage. This feature makes it difficult to force the lock open without a key. In addition, one or more remote locks may be added to the main lock. With two remote locks it is possible to provide three anchor points for a door.Type: GrantFiled: April 23, 1996Date of Patent: March 3, 1998Assignee: Reflectolite Products, Inc.Inventors: Ivanhoe E. Chaput, Petros Z. Mantarakis

Patent number: 5360505Abstract: A vertical rear door for a single-face station which has a pressurized volume and which station is used to produce corrugated cardboard. The door consists of a panel with an outer dimension slightly smaller than the inner dimensions of the door frame in which it is received. The whole periphery of the panel of the door is provided with peripheral seals resting on the inner periphery of the framework. An interlocking arrangement includes at least a hook mounted to extend in a vertical plane from the inner surface of the panel of the door and liftable so that it can move in a vertical plane by means of a lifting arrangement. The hook engages an interlocking axle which is mounted permanently on the door frame and the front part of the inner notch of the hook has a forward curvature to surround a substantial portion of the axle when the hook is engaged thereon.Type: GrantFiled: June 18, 1993Date of Patent: November 1, 1994Assignee: Peters MaschinenfabrikInventors: Jens Schulz, Martin Hoffmann, Nicolaus Goerrissen

Patent number: 5141266Abstract: A sliding door rotary latch system includes a handle assembly mounted on the sliding door adjacent its leading edge, a rotary latch assembly and locking mechanism mounted on the front post of the door frame cooperating with a strike bar on the handle assembly selectively to latch the sliding door in its fully closed position and a rear latch plate mounted on the back post of the door frame cooperating with the handle assembly selectively to latch the sliding door in its fully open position. The door mounted handle assembly includes an outer pivotal handle, an inner pivotal handle, and an inner actuation mechanism operative to allow either handle independently of the other to actuate either a pivotal front cam actuator arm or a rear pivotal latch independent of the other. Either handle may be held in its pivoted position toward the direction of sliding movement of the door during that sliding movement without adversely effecting the latching action when the door is either fully closed or opened.Type: GrantFiled: March 5, 1990Date of Patent: August 25, 1992Assignee: Cleveland Hardware & Forging CompanyInventors: Jack A. Braun, Donald McFarland, Paul Shuss
