A door latch (100, 400, 500, 600, 1200, 1300, 1400, 1500, 1600, 1700, 1800, 1900) resists opening of a door (200) beyond a predetermined amount when it is engaged and also allows the opening of the door when it is disengaged. The door latch includes a catch (220, 220′, 3220) and a base (191) that is connected to a deformable member (140, 3140, 4140, 5140, 6140) at a joint (90). The joint configures the door latch and may include a pin (190). The catch (e.g., a hook) engages a catching portion (e.g., a loop 148, 3148, 6148) of the deformable member when engaged. The deformable member may stretch at least five percent when resisting an intrusion load (F) on the door. The base may mount to a door frame (300), and the catch may mount to the door. A spring (180) may urge the deformable member toward engagement. A shield (280, 2280, 4280, 5280, 6280) may protect the deformable member and resist cutting and may pivot with the deformable member urged by the spring. A finger pocket (296) may be used to overcome the spring. A detent (187) may retain a disengaged configuration (70), and a button (130) on the pin may be depressed to release the detent. A keeper (260) may retain an engaged configuration (50), even when the intrusion load alternates. An armed configuration (40) may automatically transition to the engaged configuration upon the door reaching the predetermined amount and may be manually transitioned to the disengaged configuration upon operator manipulation. The deformable member may hyperelastically deform.

A hinge assembly is for a cowling on a marine drive. The cowling has a first cowl portion and a second cowl portion which together enclose a cowl interior. The hinge assembly has a first base frame configured for fixed attachment to an interior surface of the first cowl portion and a second base frame configured for fixed attachment to an interior surface of the second cowl portion. The second base frame is pivotally coupled to the first base frame by a connection device that enables manual removal of the second base frame from the intermediate frame without use of a tool, thus facilitating manual removal of the second cowl portion from the first cowl portion without the use of the tool.

A buckle lock assembly has a hook unit, a fixing base, a wrench unit, a buckling ring unit, and a lock. The hook unit is adapted to be securely mounted on a first locked unit. The fixing base is adapted to be securely mounted on a second locked unit and has a locking segment. The wrench unit is pivotally mounted on the fixing base. The buckling ring unit is pivotally mounted on the wrench unit and selectively clasps the hook unit. The lock is securely mounted on the wrench unit and has a locked state and an unlocked state. In a locked state, the lock engages with the locking segment to limit the wrench unit pivoting relative to the fixing base. In an unlocked state, the lock disengages from the locking segment to allow the wrench unit to pivot relative to the fixing base.

A latch assembly having a latch buckle and a latch tongue. The latch buckle includes: a buckle housing; a first lateral aperture disposed along a first side of the buckle housing; a second lateral aperture disposed along a second side of the buckle housing; a pair of h-shaped levers, each pivotally coupled to an interior of the buckle housing; a spring ring disposed between the pair of h-shaped levers; a pair of springs, each spring being coupled to an interior of the buckle housing and an h-shaped lever; and a buckle aperture disposed along a top of the buckle housing and between the pair of h-shaped levers. The latch tongue includes: a tongue plate; a plate spacer, coupled to the tongue plate; and a latch flange, coupled to the plate spacer, configured to be received by the buckle aperture. The latch tongue is selectably coupled to the latch base.

A latch structure comprising an elastic pull latch is disclosed. The top of the elastic pull latch includes a latch bar configured with a latch groove. The elastic pull latch also includes an elastic boss that moves in and out of the latch cover of the pull latch. On both sides of a box, an elastic pull latch is provided at the top and a catch groove having a catch affixed to the lower edge is provided at the bottom. When two boxes are stacked together, the catch in the catch groove of the upper box is snapped into the latch groove of the elastic pull latch of the lower box to securely connect the two boxes. When the latch is released, the catch of the upper box blocks the elastic boss of the latch of the lower box to prevent the latch from retracting inwards.
