A bifold door includes a first hinge and a second hinge configured to rotatably couple the bifold door to a doorframe. The bifold door includes a slider configured to slide within a track of the doorframe as the bifold door is opened and closed. At least one of the first hinge, the second hinge, and the slider includes a spherical bearing and a pin.

A closing device configured to close an outer shell opening of a surface ship, including several substantially vertically mounted shutter lamellas and a drive device by means of which the shutter lamellas can be actuated such that they move between a closed position and an open position.

A pneumatic system utilizes a pneumatic cylinder to deploy and retract a bimini top. The pneumatic system also provides pressurized air to additional peripheral devices. A bimini top assembly includes links to deploy and retract a bimini top with an actuator.

The present disclosure a hinge blade structure comprises two hinge blades, a connection sleeve, a fixed rod, a screw sleeve, a plug, a damping positioning pull rod, and an air cylinder. The damping positioning pull rod and the air cylinder are both disposed in the connection sleeve and disposed between the fixed rod and the plug, the air cylinder is relatively secured to the plug, the damping positioning pull rod is relatively secured to the screw sleeve, the damping positioning pull rod is slidably connected to an inner side of the air cylinder along a length direction of the connection sleeve, the damping positioning pull rod and the air cylinder cooperate to define an air chamber, the air cylinder comprises an air chamber vent through hole and an air inlet, and a resistance force generated between the air chamber and the damping positioning pull rod achieves positioning.

A moveable component assembly includes a seat assembly, a track system, and a locking mechanism that secures the seat assembly in position. The track system is coupled at least indirectly to the seat assembly and guides the seat assembly along a path between a first and second position. The seat assembly is secured in the second position when the seat assembly is disposed away from the deck's walking surface, thereby resulting in the components of the track system being frictionally coupled. A floor panel includes a locking mechanism and a series of alignment surfaces that guide the floor panel into position, which is secured by the locking mechanism.

Provided is an angle-adjustable positioning and self-closing hinge for a highly sealed door, comprising a hinge part, a fixing base, a fixing bar, a threaded sleeve, a threaded ring, a plug, and an adjustment socket; the hinge part is provided with a bushing and a leaf; the fixing base is provided with a bushing; the fixing bar has a screw; a threaded sleeve is fastened inside the bushing, the plug is fastened inside the bushing, and the threaded sleeve and plug are spaced apart; between the threaded sleeve and plug in the two bushings are disposed the fixing bar, the two magnets, two springs, and the adjustment base; the screw of the fixing bar is screwed to the threaded sleeve.

A slide system includes a component assembly, a track system, a floor panel, and a below-deck cavity. The track system is coupled at least indirectly to the component assembly for guiding movement of the component assembly along a path. The floor panel includes an upper surface. The below-deck cavity is disposed below the floor panel. The component assembly is located substantially above the floor panel. The track system is located within the below deck cavity and below the upper surface.

An electronically powered window for a watercraft consists of a shuttle frame, a sliding mechanism, a window pane, and a bottom edge support groove. A first lateral support arm and a second lateral support arm of the shuttle frame along with the bottom edge support groove helps position the window pane within the shuttle frame. The sliding mechanism allows the user to position the window pane such that the window is in an open configuration or a closed configuration. To do so, a first lateral edge is slidably positioned along the first lateral support arm. Moreover, a second lateral edge is slidably positioned along the second lateral support arm.

An escape apparatus for a vessel includes a support frame that is configured to be installed at the vessel and that defines defining an exit opening, an escape door located at an inner side of the exit opening and configured to open and close the exit opening, where the escape door defines an accommodation space, a floater located in the accommodation space of the escape door and configured to be raised relative to the support frame, and an unlocking device configured to, based on being pushed by the raised floater, release coupling between the escape door and the support frame.

A closing device configured to close an outer shell opening of a surface ship, including several substantially vertically mounted shutter lamellas and a drive device by means of which the shutter lamellas can be actuated such that they move between a closed position and an open position.
