Patent number: 8800208Abstract: A system and methods for controlling operation of hydraulic cylinders includes monitoring position of the cylinders relative to one another, and correction of misalignment of the cylinders should they become misaligned. Further, monitoring can be of a swing-type door operated using the cylinders, which can operate the door at different speeds. Further, as the door creeps open from a closed position or closed from an open position, correction is also made.Type: GrantFiled: December 10, 2012Date of Patent: August 12, 2014Assignee: Hi-Fold Door CorporationInventors: Richard D.

Patent number: 6547292Abstract: A door closing mechanism for pulling a door tight to a frame to which the door is mounted comprises a latch arm assembly having a latch arm pivotally secured to a panel of the door and pivotable between a first, open position and a second, latched position. An activating mechanism is operably connected to the latch arm assembly by a connecting apparatus and actuates the latch arm between its first and second positions. A latch member is secured to the jamb in which the door is mounted and is arranged and constructed so that when the latch arm is moved into its second, closed position, the latch arm engages the latch member and exerts force upon the latch member in a direction substantially normal to the plane of the door so as to cause the door to contact the door frame over substantially its entire height.Type: GrantFiled: March 13, 2000Date of Patent: April 15, 2003Assignee: Hi-Fold Door CorporationInventor: Richard D.

Patent number: 5343923Abstract: A latch assembly for overhead bifold doors. The latch assembly is operated by the same manual or powered winch mechanism that is used to open and close the overhead bifold door. A latch assembly may be mounted to one or both ends of the overhead bifold door, and includes a latch arm that is moved to a latching position at the end of the door closing cycle. A latch member is fixedly positioned to the door jamb adjacent the latch assembly, and when the latch arm is drawn down, the latch member is located between it and the overhead bifold door, causing the overhead bifold door to be securely latched in its closed position until the winch mechanism is activated to begin the overhead bifold door opening cycle.Type: GrantFiled: December 8, 1992Date of Patent: September 6, 1994Assignee: Hi-Fold Door CorporationInventor: Daniel N.
