An enclosure for electrical installations includes a bottom and a cover fastened to the bottom by a fastening device including a latch which, supported by a bearing, is turnable in relation to the bottom to open/close the fastening device. An arm is bearing-mounted to the latch. The cover has a detent to receive the arm and to fasten the cover to the bottom by the arm. The detent is located in a recess formed in an edge of the cover. Attached to the arm there is a cover piece to attach to the detent in the recess of the cover. The cover piece includes first and second outer surfaces which at the recess of the cover make the outer surfaces of the cover uniform, such that the discontinuities formed by the recess of the cover on its top and side surfaces are concealed.

A cowling has first and second cowl portions that enclose a powerhead on a marine drive. A latching assembly is for latching the first and second cowl portions together. The latching assembly has a retainer portion fixed to the first cowl portion and a latching portion fixed to the second cowl portion. The latching portion comprises a latch arm and a bell crank, the latch arm and bell crank being rotatable into and between a latched position in which the latch arm is latched to the retainer portion and an unlatched position in which the latch arm is unlatched from the retainer portion. A novel detent mechanism mechanically retains the latch arm and bell crank in the latched position and alternately in the unlatched position. A pair of bolted connections that fix the first and second cowling portions together and are located on opposite sides of the cowling.

Implementations of detachable window systems may include: a main panel including one or more windows therein, the one or more windows in the main panel each having a window casing, a screen, and a window opening mechanism; an upper panel hingedly coupled to an upper side of the main panel; and a lower panel hingedly coupled to a lower side of the main panel opposing the upper side. The window opening mechanism on each of the one or more windows may be used to open the window to permit air to flow through the screen.

A locking device for connecting a first housing to a second housing is provided, wherein the first housing and the second housing are arranged along a first direction. The locking mechanism includes a first hook, a second hook, a movable member, and a driving member. The first hook and the second hook are affixed to the first housing, and respectively have a first engaging recess and a second engaging recess. The first engaging recess and the second engaging recess are arranged along the first direction. The movable portion has an engaging portion. The driving member is connected to the second housing and the movable member, and is configured to drive the movable member to move relative to the second housing. When the first housing is affixed to the second housing via the locking mechanism, the engaging portion is accommodated in the first engaging recess.

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 mechanism configured to engage a mating pin is disclosed. In various embodiments, the latch mechanism includes a latch frame; a latch arm pivotally mounted to the latch frame at a pivot axis; and a bias member configured to apply a load to the latch arm in a transverse direction generally perpendicular to the pivot axis and to bias the latch arm from rotating in a first rotational direction about the pivot axis and from rotating away from the mating pin.

An adjustable buckle lock has a hook unit, a fixing unit, a wrench unit, an adjustment assembly, and a buckling ring unit. The hook unit can be securely mounted on a first locked object, and the fixing unit can be securely mounted on a second locked object. A pivotal end of the wrench unit is pivotally mounted on the fixing unit. The adjustment assembly is mounted on the wrench unit, and the buckling ring unit is pivotally mounted on the adjustment assembly and selectively hooks on the hook unit. With the moving of the buckling ring unit controlled by the adjustment assembly, the distance between the buckling ring unit and the hook unit is changed, and thus the pulling force for the buckling ring unit hooking on the buckling ring unit is adjusted, which ensures the first locked object and the second locked object are sealed together by a suitable force.
