Abstract: An inertia blocking mechanism operably connected to a door handle on a vehicle having a handle chassis. A counterweight is operably connected to the handle chassis and is pivotally rotatable about a first pivot axis between a non-actuated position and an actuated position. Stanchions extends from the handle chassis. A spring-biased primary inertia lever is operably connected with the stanchions and is pivotally rotatable about a second pivot axis. The spring-biased primary inertia lever is biased to a first position out of rotational alignment with the counterweight. An auxiliary inertia lever is pivotally rotatable about the second pivot axis and is adapted to move the primary inertia lever into a second position in rotational alignment with the counterweight, which prevents the counterweight from rotating downward into the actuated position, thereby actuating the exterior door handle thereby preventing the exterior handle from actuating and releasing the latch.

Abstract: A gate and door latch having alternate means of opening and closing either by a horizontal sliding action of a striker or pivoting of the striker. The striker is manipulated into an open or closed position by means of latching or unlatching the striker member from a pronged keeper. A striker slot allows the striker member to be slid horizontally from side to side in an open or closed position or to pivot about a striker pivot bolt in an open or closed position. A rear lever handle is secured to the back side of the gate or door allowing for opening or closing the latch from the rear by rotating the rear lever handle. Rotation of the rear lever handle actuates a lever located on the front side of the gate and door latch causing the lifting and pivoting of the striker into an open position.

Abstract: A gate latch has a handle with a cojoined adjustably sized elongated rigid metal rod, which rod is rotatably disposed in sleeves frictionally retained within a drilled hole in a fixed post of a fence. The rod is formed with a plurality of spaced parallel threaded through holes. The handle has a transverse hole and is mounted to the rod by a bolt passing through the handle hole and one of the rod holes disposed at the end of the rod on the outside of the post. The rod is operably connected to a spring return locking plate for locking a gate rod which gate rod is fixedly mounted to an openable gate. The user first drills the post hole to receive the elongated rod slidably disposed in the sleeves, and then cuts the elongated rod to a length to accommodate the thickness of the post, and then attaches the handle at the hole adjacent the cut end of the elongated rod. The user in operating the gate latch rotates the handle downwardly which in turn rotates the elongated rod in the post hole.

Abstract: This invention is a combination door latch actuating handle and an exit/entry operator support assembly, mainly for the interior but also usable for the exterior of a vertically oriented door for any agricultural or industrial equipment with a cab. It consists of two nearly full width of door, U-shaped, interlocking and generally horizontally mounted pieces. One U-shaped piece is a mounting/pivot and stops bracket attached to the door, and the other is a swingable door latch actuating handle/grab bar. An unlatching position is oriented generally upward and outward, actuating the latch with a cable; and a simple gravity designed latching position is oriented inwardly and downward. These motions are in perfect harmony with the operator's movements as one exits or enters the cab. It increases the safety of an operator over existing designs by providing a more visible, accessible and easier to use door latch actuating handle for emergency exits.

Abstract: A gate latch, using neither gravity nor springs, is forceably opened and closed from either side of the gate by a handled lever that passes between the gate and gate post an into an arcuate cam slot. When the lever is lifted, it forces open the latch to eject a gate pin and, when lowered, forces the latch to close on the gate pin.

Abstract: Locking latch device for use with roll-up doors on trucks and tractor-trailer vehicles which will automatically latch when closing the door and which can only be opened after a pendulous latch member is set to an unlatching position by the use of a release member. A locking device is provided to render the latching mechanism inoperable to prevent unauthorized opening of the roll-up door.

Abstract: A latch for use with a gate includes a latch body having a planar mounting surface on a rearward side thereof with a pair of space apart flanges which receive a bolt in openings thereto. The bolt is positioned parallel to the surface of the gauge and is slidably and rotatably disposed within the flange openings. An enlargement on one side of the bolt will allow the bolt to pass through one of the flanges when in a predetermined angular position for removal. However an offturned end of the bolt extends rearwardly of the mounting surface, and the bolt enlargement is so oriented such that the bolt is not removable from the latch body when the body is normally attached to the gate.

Abstract: A gate latch in which a locking bolt is located so as to extend through vertical guides at the opposite ends of a latch body. A keeper is mounted on the latch body at the end thereof distal from the free or latching end of the bolt and an offset portion of the bolt is located so as to be slidable along the keeper. Additionally, the bolt is pivotable about its line of contact with the keeper so that the gate may be latched and unlatched. The keeper is provided with a deformation resembling an S-shaped curve in the horizontal plane to provide obstruction to the free sliding of the bolt and thus prevent inadvertent movement thereof.

Abstract: A gate latch including a body-mounted latch bolt which may be actuated to an elevated position from outside the gate by a lever extending through the gate to disengage the bolt from the latch strike. A lock device is provided which may be key-operated on the outside of the gate to locate a detent or cam element in a position to prevent movement of the lever, thus preventing the gate from being opened from the outside. Additionally, or alternatively, a cam or crank-like element may be actuated by the lock to prevent rotation of the latch bolt to unlock the gate. The element may be mounted so as to have a relatively slidable portion thereon which is actuatable, against a spring biasing force, to allow the bolt to be rotated, by one of the inside of the gate, to open the gate.
