Abstract: A skylight or roof hatch that is manually opened and closed. The skylight is formed of a window mounted to a casing frame by way of one or more hinges, which allows the window to open and close. One or more gas springs mounted between the window and casing frame are configured to exert force against the inside of the window. The gas springs are used to urge the window into an open position. Once in the open position, the window is closed by overcoming the biasing force exerted by the gas springs. This is achieved by winding in a cable that is connected to the window. A single pulley wheel that is mechanically linked to other mechanical elements is utilized to spool in the cable connected to the window in order to close the window and to unlock a reel lock to allow for automatic opening of the window.

A single pulley wheel is part of a control unit which is utilized to spool in the cable connected to the window in order to close the window and to unlock a reel lock to allow for automatic opening of the window.

Abstract: A ball-shaped mechanism for connecting two ends of a ball chain. The mechanism is formed of two ball halves that may be separated to receive two link members and then secured together to hold the link members in place. Each of the ball halves has two opposing slots that are sized and shaped to receive a link member. When the two ball halves are brought together along their respective equatorial planes, the respective slots form pockets that secure link member ends within the ball-shaped connection mechanism.

Abstract: A skylight or roof hatch that is manually opened and closed. The skylight has one or more hinges allowing it to open and close and it also has one more gas springs that exerts constant force against the window urging the window into an open position. The window is closed to overcome the biasing force exerted by gas springs by winding in a cable that is connected to the window. A single pulley wheel that is mechanically linked to other mechanical elements is utilized to spool in cable in order to close the window and to unlock a reel lock to allow for automatic opening of the window.
