A lever-lock release system is configured to releasably couple two objects together, for example a parachute and a payload. The lever-lock release system may comprise a first lever and a second lever, each rotatably coupled to a rigid base. When activated, the levers cascadingly rotate to release a first object and a second object. With these systems and related methods, various failure modes may be eliminated, such as undesired premature deployment of recovery parachutes during aerial delivery.

The invention relates to a locking device for locking a first component, in particular a door leaf, to a second component, in particular to a door frame, having a catch element for fastening to the first or second component, the catch element comprising a first latching recess; having a latching unit for fastening to the second or first component; the latching unit comprising a first latching body for engagement with the at least one latching recess of the catch element; the latching unit comprising a release element which comprises a first receiving opening for receiving the first latching body; and the release element can be moved between a rest position, which arranges the first latching body in the first latching recess of the catch element and in the receiving opening of the release element, and a release position, which releases the engagement between the first latching body and the first latching recess of the catch element. The invention also relates to a sliding door having such a locking device.

A door latch assembly for an automotive vehicle door includes a gearless cinch actuator. The cinch actuator includes an extensible housing member connected to a threaded rod by a nut. The extensible housing member is also connected to a cable for cinching the door. A motor rotates the threaded rod, which moves the extensible housing member between rest and cinched positions. The motor is connected to the threaded rod without the use of gears. An anti-friction agent, such as a combination of a PTFE-containing coating and PTFE-containing grease, is applied between the nut and the threaded rod. The materials and anti-friction agent used at the interface of the threaded rod and nut together provide a friction coefficient () of about 0.045 or less.

A latch including a housing having side members each having an elongated slot, a bolt mounted rotatably to the housing and positioned between the side members of the housing, an adjustment mechanism, and a pin and roller positioned slidably within the elongated slots of the side members of the housing. The adjustment mechanism includes a compression spring, a central cap for receiving the pin and roller therethrough, and a nut for adjusting the load on the compression spring. The bolt is moveable between a first, closed position, in which the pin and roller are engaged with the bolt, and a second open position, in which the pin and roller are disengaged from the bolt. The latch can be opened automatically when a defined load, as adjusted by the adjustment mechanism, is provided on the bolt to disengage the pin and roller from the bolt.

A hold open rod assembly includes an outer tubular structure and an inner tubular structure positioned for telescoping movement relative to the outer tubular structure. A locking mechanism retains the hold open rod assembly in an extended state to support a panel of an aircraft in an open position at the selection of a user.

A roller tongue (1) for a locking system includes a spindle, which is securable to the locking system, and a roller (2) rotatably mounted on the spindle. The spindle is formed as a multi-part element and includes a pin (3) and an adapter element (4). The adapter element (4) includes a receiver (5) for the pin (3) arranged eccentrically in the adapter element (4) and is fixable in different orientations onto the pin (3).

Bonded or slide on sleeve and cover devices, and replacement gate latches and methods for preventing injury with oar, fork and U-shaped gate latches that are pivotally attached to fixed support post next to an opening in a fence. The sleeves and covers and replacement oar, fork and U-shaped gate latches have enlarged blunt tips that can include bulbous, dome and ball shapes that prevent injury from children or adults that come into contact with the gate latches.

A propellant flow actuated piezoelectric igniter device using one or more hammer balls retained by one or more magnets, or other retaining method, until sufficient fluid pressure is achieved in one or more charging chambers to release and accelerate the hammer ball, such that it impacts a piezoelectric crystal to produce an ignition spark. Certain preferred embodiments provide a means for repetitively capturing and releasing the hammer ball after it impacts one or more piezoelectric crystals, thereby oscillating and producing multiple, repetitive ignition sparks. Furthermore, an embodiment is presented for which oscillation of the hammer ball and repetitive impact to the piezoelectric crystal is maintained without the need for a magnet or other retaining mechanism to achieve this oscillating impact process.
