A self-locking device for hanging objects on a mounting surface is disclosed. The self-locking device includes a mounting bracket and a locking arm member engaged with a track portion of the mounting bracket. The track portion comprising a pair of guide portions, a pair of lip portions extending from a lower end of the guide portions, a pair of rotation portions extending from an upper end of the guide portions, and a slot extending between the pairs of guide portions, lip portions and rotation portions. The arm member being mated with the track portion such that the arm member is translatable along the track portion. The arm member comprising a tip portion, a base portion positioned at least partially within the slot, and at least one pair of projections extending from the base portion that engage with one of the pairs of guide portions, lip portions and rotation portions.

A pump mounting frame comprising a latching device for releasably mounting a pump apparatus. The latching device has a body portion having a latch aperture for receiving a latch pin; and a latching member for releasably retaining the latch pin in the latch aperture. The latching member is movable between a closed position and an open position. The latching member has a first arm for retaining the latch pin in the latch aperture when the latching member is in the closed position. The latching member has a second arm for biasing the latch pin out of the latch aperture when the latching member is displaced from the closed position to the open position. The present disclosure also relates to a method of moving one or more pumps using the pump mounting frame.

A fitting part for tool-free fastening in a bore in a panel includes a radially outwardly expandable expansion sleeve for insertion into the bore and a fitting housing, which is mounted in the expansion sleeve so as to be rotatable about an axis of rotation between a starting rotary position and a final rotary position, has a lever arm which is arranged outside the expansion sleeve and has a latching device, and has an expansion contour which is arranged inside the expansion sleeve and, upon rotation of the fitting housing in the expansion direction of rotation from the starting rotary position to the final rotary position, expands the expansion sleeve radially outwards.

A self-closing and locking device for hanging objects on a mounting surface is disclosed. The device includes a mounting bracket and a locking arm member translatably engaged with an elongated track portion of the mounting bracket. The track portion comprises a pair of guide portions defining a slot therebetween, and rear recesses in a back side of the guide portions. The rear recesses comprise lower locking portions, and upper rotating portions that are deeper than the locking portions. The arm member comprises a base portion that is positioned within the rear recesses, and an arm portion that extends from the base portion and through the slot. The device is configured such that the arm member is oriented in a closed position when the base portion is engaged with the locking portions, and orientable in an open position when the base portion is engaged with the rotating portions.

A gated safety hook includes a structural, load bearing frame, a gate, and a user actuated catch. The gate closes automatically in response to an object being mounted on the hook, the catch automatically moves to lock the gate closed in response to an object being mounted on the hook, and the gate cannot be opened with an object mounted on the hook without engaging against the object.

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.

A slingbar includes a sling attachment member. The sling attachment member includes a frame including a base having a top end and a bottom end, and a hook extending from the bottom end to a hook terminus. The hook terminus and the top end of the base define an opening. The hook, base, and opening bound an interior of the attachment member. A closure element includes an outboard gate hinged to the hook terminus and an inboard gate hinged to the base. The gates have a default state in which each gate extends laterally only part way across the opening.
