An aircraft having a hatch and a fall-protection device includes a structure comprising a roof pierced with an opening, a cover plate, and a lock provided to adopt a locking position, in which the lock holds the cover plate in the closed position in the opening, or, alternatively, an unlocked position, in which the lock does not hold the cover plate. The aircraft further comprises at least one fall-protection device provided so that, when the lock moves into the unlocked position, it is in a first position to allow movement of the cover plate under the influence of gravity from its closed position to an intermediate position, in which the cover plate is suspended from the structure and then moves from the first position into a second position, during which movement the cover plate moves from the intermediate position into an open position, no longer attached to the structure.

A handle mechanism includes a gear drive having an interior end and an exterior end; an inside handle fixed to the interior end; a button; a finger; a handle drive; an outside handle; and a spring. The button has an interior end and an exterior end, which is positioned within the exterior end of the gear drive. The handle drive is positioned within the exterior end of the gear drive and is rotatable relative thereto. The outside handle and the handle drive rotate together. The outside handle moves between a first position, wherein it is constrained from rotation, and a second position. The finger is fixed to the exterior end of the button, which moves between a first position, wherein the finger causes the gear drive and the handle drive to rotate together, and a second position. The spring biases the button and the outside handle toward their first positions.

A cover unit includes a first divisional cover, and a second divisional cover. The first divisional cover and second divisional cover include a first locking portion and second locking portion, respectively. The first locking portion and second locking portion are made of an elastomer. The first locking portion and second locking portion lock to one another to couple the first divisional cover to the second divisional cover, or vice versa. The first locking portion includes a prong-shaped main tab. The second locking portion includes a main bore into which the main tab is insertable. The main tab includes a main claw disposed on the leading-end side, and locked to the main bore to inhibit the main tab from coming off from the main bore.

Methods and apparatus for using a look on a door lever handle are disclosed. The lock includes a base configured to mount the lock to a door having a lever handle and a lever handle guard pivotally attached to the base, the lever handle guard being pivotable between a locking position and a non-locking position. The lever handle guard is securable in the non-locking position. The lever handle guard includes first and second guard portions arranged to prevent rotation of the lever handle when the lever handle guard is in the locking position. When the lever handle guard is secured in the non-locking position, the first and second guard portions are arranged to permit rotation of the lever handle without contacting the first and second guard portions.

The present invention is a positioning mechanism device to prevent the motion of one surface with respect to a second surface, in one direction. The positioning mechanism uses a linear adjusting lock, an actuator, and an over-ride mechanism. The linear adjusting lock uses a coil spring to hold a rod in place. When firmly coiled, the coil spring is able to grip a smooth rod and prevent axial motion. When the coil spring is uncoiled, slightly, it releases its grip on the smooth rod, allowing axial motion. The positioner mechanism uses an actuator and release blade to release the coil spring. Additionally, the over-ride mechanism can be used to release the release blade in one direction without use of the actuator. When the coil spring is released by either the actuator or over-ride mechanism the two surfaces can be re-positioned relative to one another.

A gate latch assembly including an actuating member, a moveable rod, and a strike plate. The actuating member transfers movement of a first handle to a second handle. The actuating member includes a cam surface which interacts with the moveable rod to transition the gate latch assembly from a locked configuration to an unlocked configuration. A biasing element biases the actuating member.

An aircraft door latch arm rotation limiting device incorporates a flexible strap having a proximal end and distal end. The distal end is insertable through a loop eye proximate to an aircraft door. An elongate sleeve is disposed on the proximal end of the flexible strap and the sleeve is received over a rotatable latch arm of an aircraft door. A first receiving element intermediate the proximal and distal ends of the flexible strap releasably engages the distal end of the flexible strap to establish a first predetermined looped strap length restricting rotation of the lever beyond a partially open position. A second receiving element is disposed between the first receiving element and the proximal end on the flexible strap to releasably engage the distal end to establish a second predetermined looped strap length preventing rotation of the lever from a closed position.

The present invention relates to a lock having a lock housing (3, 4) together with a lock cover (2), a lock case (9), a locking mechanism which is mounted on the base surface of the lock case (9), and an activation device for opening the locking mechanism. An activation lever of the activation device is at least partially covered by a pivotable flap (5) of a lock covering means (2, 3). The invention also relates to a method for manufacturing the flap together with a lock cover (2) by injection molding.

A latch actuator comprises a motor, a speed reduction gearing coupled to an output shaft of the motor, a spindle, and a motion conversion mechanism. The spindle has a threaded portion in engagement with the speed reduction gearing. The spindle is supported to be rotatable about an axis. The threaded portion is rotationally fixed relative to the spindle. The motion conversion mechanism is configured to cause a displacement of the spindle along the axis when the spindle rotates.
