Patent number: 11408210Abstract: A latch mechanism includes a handle connected to a pin by a linkage. The linkage converts rotation of the handle relative to a frame into axial movement of the pin between extended and retracted positions relative to the frame. The pin engages with a pre-load adjustment mechanism in the extended position to apply a pre-load through the linkage that biases the pin toward the extended position. The pre-load adjustment mechanism is adjustable to set the pre-load through the linkage to a predetermined value as selected by a user.Type: GrantFiled: January 17, 2019Date of Patent: August 9, 2022Assignee: Hartwell CorporationInventors: Brody Wayne Collins, Bo D.

Patent number: 9650807Abstract: The present disclosure includes a tool operated channel latch used to secure a panel against a structure. The latch includes a bracket which mounts to a movable panel and includes an actuating mechanism to open and close the latch. A bolt is pivotably retained relative to the bracket for engaging against the structure closed by the panel. A lock assembly is carried on the actuator to engage a link which is movably coupled with both the bolt and the actuator. The lock assembly includes extending portions to engage at least one corresponding opening of the link. The link provides an over center toggle condition to retain the latch in a locked position until intentionally actuated by an operator.Type: GrantFiled: February 18, 2015Date of Patent: May 16, 2017Assignee: Hartwell CorporationInventor: Thomas John Helsley

Patent number: 9580945Abstract: The present disclosure includes a telescoping hold open rod which is controllably lockable and unlockable for use in holding a panel such as a nacelle open to provide a user access to an opening covered by the panel. The hold open rod is useful in allowing the rod to be unlocked and telescopically collapsed. The rod can be locked into a telescopically extended position to maintain the panel in an open position relative to the opening to facilitate access to the opening without the rod telescoping closed. A retention assembly includes structures and devices to maintain the rod in an open condition although subject to compressive loads.Type: GrantFiled: November 3, 2013Date of Patent: February 28, 2017Assignee: Hartwell CorporationInventor: Bo D.

Patent number: 9500014Abstract: The present disclosure includes a hinge assembly for use in a hinged attachment of a panel relative to a frame and providing movement of the panel relative to the frame. A link which provides an extension or reach motion and positioning of the assembly, shown for purposes of illustration and not limitation in the form of a gooseneck arm, is provided in the hinge assembly to facilitate an extended range of motion of the hinge assembly. A first spherical bearing assembly and a second spherical bearing assembly are operatively associated with a bearing end of the link to provide multiple degrees of motion while securely retaining the panel relative to the frame. The hinge is intended to provide universal application of a single version of a hinge which can be used in multiple locations as facilitated by the multiple degrees of motion provided by the bearing end of the link.Type: GrantFiled: October 17, 2013Date of Patent: November 22, 2016Assignee: Hartwell CorporationInventors: Douglas Soren Nielsen, Timothy S. Rozema

Patent number: 9169678Abstract: A latch mechanism for use in attaching portions or panels on an aircraft. The latch mechanism and related method include a detent mechanism for releasably coupling a bolt portion of the latch to a handle portion of the latch. The latch allows the bolt and handle to conjointly pivot with respect to a corresponding mounting bracket. The latch operates to relieve pressure in an excess pressure condition when the forces associated with the detention mechanism are overcome.Type: GrantFiled: December 3, 2010Date of Patent: October 27, 2015Assignee: Hartwell CorporationInventor: Timothy S. Rozema
