  • Patent number: 5607195
    Abstract: A flexible over-center draw latch is disclosed which is adapted for securing together two closure members. The latch comprises a keeper mounted on the one closure member and a latch assembly mounted on the other closure member. The latch assembly includes a base which is adapted to be mounted on the second closure member, a substantially elastic latch body pivotally connected to the base and a lever which is pivotally connected to the latch body. As the latch is fastened, the lever engages the keeper to secure the panels together. The substantially elastic body member becomes elongated along its longitudinal axis as the latch is fastened. The loads which are produced by the latch body as it is elongated are distributed over the latch which ensures the connection of the components. The latch assembly also provides reinforced connection between the latch body with the base and the lever. The latch also provides a more secured fastened position due to engagement of the lever and the keeper.

  • Patent number: 5033778
    Abstract: An over-center toggle latch which can be integrally molded with the first and second members of a case. The over-center toggle latch includes a hinge arm that has first and second spaced ends. A first living hinge attaches the first end of the hinge arm to the first case member. A second living hinge is for coupling a lever arm to the second end of the hinge arm. An engagement member-receiving seat is formed on the second member of the case. An engagement member is mounted to the lever arm and is spaced from the second hinge. The engagement member pivotally engages the seat with the hinge arm in an over-center position with respect to the engagement member. The latch is configured for use with first and second case members that have sides and edges. When the first and second case members are secured by the latch, the edges are generally coplanar and perpendicular to the sides.

  • Patent number: 4925221
    Abstract: A toggle latch is shown which retains a structure, such as an aircraft door, latched against a second structure, such as the fuselage. The latch includes a housing having a latch actuator joined to the housing a first pivot point and a latch member joined to the housing at a second pivot point. A linkage joins the latch actuator and latch member at third and fourth pivot points. In the latched position, the fourth pivot point is positioned past a center line between the first and third pivot points to create the over-center, toggle effect of the latch. A safety catch is pivoted within the latch actuator which extends into a passage in the actuator. The safety catch also engages the housing when the toggle latch is in its latched position to lock the latch closed. Insertion of a tool into the passage engages the safety catch to remove it from its locking contact with the housing and free the latch actuator for opening the latch.

  • Patent number: 4911485
    Abstract: A latching structure defined by a mount, a handle pivotally mounted to the mount and linked with a latch pin slidably mounted in the mount. The linkage between the handle and the latch pin includes first parallel links pivotally mounted to the handle and pivotally mounted to the latch pin. Second links are pivotally mounted to the first links and to a spring block slidably mounted on the latch pin. A spring is placed in compression between a shoulder on the latch pin and the spring blocks. Consequently, the linkage mechanism operates to actuate the latch pin with the handle and create an overcenter mechanism to bias the entire mechanism to either a fully opened position or a fully closed position. A gasket is provided on a flange associated with the handle to seal the latch mechanism when the mechanism is strongly biased by the spring into the closed position.

  • Patent number: 4907831
    Abstract: A catch device is described of the type in which a fork element is thrust by a striker pin during closure of the door of a vehicle to rotate to come into snap engagement with a catch element operable to lock it in a closure position; its principal characteristic lies in the fact that it is provided with a supplementary spring pivotally attached eccentrically at one end to the fork element and at the other end to an attachment point fixed with respect to this latter, in such a way that the initial rotation of the fork element causes an eccentric elastic reaction of the spring which forces the fork element to complete its rotation with a reduced door-closing movement so as to reduce the door closure force.

  • Patent number: 4889056
    Abstract: A generally circular cover for closing a hatch opening in a railroad car hopper is connected to a diametral support bar for limited pivotal movement to provide uniform gasket loading between the cover member and the hatch coaming. One end of the support bar is hinged to the hopper roof and the opposite end includes a cam surface and laterally projecting retaining pins for engagement with a latch member. The latch member has a somewhat channel shaped portion pivotally connected to a link which, in turn is also pivotally secured to the hopper roof. The link includes opposed trunnion portions which are engageable with the cam surface to forciby engage the support bar to hold the hatch cover closed. The latch member includes open ended slots which are engageable with the retaining pins in such a way that the latch member will not disengage from the support bar when the latch member is swung to the release position if fluid pressure within the car hopper is sufficient to force the cover toward an open position.

  • Patent number: 4793643
    Abstract: Disclosed is a mechanism for closing and locking two doors of the cowling of an aircraft engine. This mechanism includes a bolt which is received in a chamber of a receptacle. The bolt is connected to one door and the receptacle is connected to the other door so that, upon closure of the two doors, the bolt slips into the chamber. A cam attached to a rotary member housed within the chamber enables a single mechanic to close the doors and lock them snugly. This cam engages a finger on the bolt upon rotation of the rotary member which draws the bolt into the chamber by pulling against the finger. The cam moves into an over center position which securely locks the bolt in place without locking bolt travel. A locking device is additionally provided for locking the rotatable member in position when the bolt is locked in place. This locking device has a plunger which provides audible signals when the cam is in the fully opened position and when the mechanism is securely locked.
