Patent number: 5931512Abstract: A latch mechanism for a wafer container includes a box sealable to a base plate to form an air-tight space for holding at least one wafer therein. The latch mechanism is located on the base plate and includes a U-shaped latch plate and a cam mechanism. The latch plate has a hook member at a front end thereof. The hook member includes a 7-shape hook with a bottom end pivotly engaged with the base plate and a top end pivotly engaged with the front end of the latch plate. The cam mechanism includes a cam and a linkage bar with a roller disposed therein. One end of the linkage bar attached to the latch plate. Another end of the linkage bar has a pin engaging with a slot formed in the cam. The pin and the roller form a positive and movable engagement with the cam. By turning the cam, the linkage bar and latch plate will have linear motion and trigger the hook to engage the box securely to the base plate or allow the box disengaging with the base plate.Type: GrantFiled: July 23, 1997Date of Patent: August 3, 1999Assignee: Industrial Technology Research InstituteInventors: Horng-Kuang Fan, Jyhjone Lee, Gwo-Jou Huang

Patent number: 5915764Abstract: A security door assembly or locking mechanism for securing a single door in locking engagement with an adjacent door jamb structure comprises a first elongate metal blade to be received by a matching elongate groove in a vertical edge of a door. A second elongate metal blade is received by a matching groove in an upper horizontal edge of the door. Mechanical devices are provided for moving said blades partially from the grooves in the door into engagement with receiving grooves in the adjacent door jamb structure to lock the door. The vertical and horizontal blades are coupled together by a linkage mechanism which enables both blades to be operated simultaneously upon actuation of a single lever or knob. The blades and the linkage mechanism are mounted in an L-shaped housing inserted into grooves formed in adjacent edges of the door. Elongate metal strips are provided to be mounted over the grooves in the door jamb.Type: GrantFiled: July 17, 1997Date of Patent: June 29, 1999Inventor: Edwin A. MacDonald

Patent number: 5489130Abstract: A overhead door lock which may be used with both manually operated and motor operated doors. The lock has a base adapted to be mounted on the door, and has a mounting plate and a pair of spaced apart legs. Each leg carries a slide aperture, and one leg includes a lockout hole. A striker plate is attached to the door channel in a position collinear with the base. A spring biased striker is carried by the base and when the door is manually operated, the striker is placed in an operative position where it slides freely through generally aligned slide apertures. When the door is motor operated, the striker may be placed in an inoperative lockout position by placing one end of the striker in the lockout hole. When the striker is in the inoperative lockout position, it cannot contact the striker plate when the door is in the closed position.Type: GrantFiled: January 18, 1994Date of Patent: February 6, 1996Inventor: Ronald L.

Patent number: 5409272Abstract: A latch assembly is mounted in an aperture formed in a first member. The latch assembly includes a housing which is received within the aperture of the first member and includes an aperture extending therethrough. A slide is included which is received through the aperture of the housing. A pawl is also provided on the slide. A handle is pivotally attached to the slide for facilitating movement of the slide and pawl axially as the handle is pivoted between closed and opened positions. The pawl engages a second member in a latched position when the handle is pivoted to its closed position. The handle is also adapted for movement in a direction generally along a longitudinal axis thereof upon the closing and the opening of the handle which enables a first end of the handle to be positioned proximate to the housing when the handle is in its closed position.Type: GrantFiled: June 28, 1993Date of Patent: April 25, 1995Assignee: Southco, Inc.Inventor: Edward A.
