A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

A vehicle door unit comprises a rotating lever supported rotatably about a first shaft at a first end, a door mounting coupled rotatably about a second shaft to a second end of the rotating lever, a door attached to the door mounting and being configured to cover an opening in a vehicle and to close off a vehicle interior, and a drive unit configured to rotate the rotating lever about the first shaft between a closed position and an open position. The rotating lever is configured to move the second shaft, on a movement from the closed position to the open position, on a circular path, due to which the door mounting is first moved into the vehicle interior and, on further rotation of the rotating lever, out of the vehicle interior.

The present invention relates to a breakout sliding door system for use in retail and other buildings. The system includes at least one door configured to slide open and closed and also breakout in at least one direction when a force is exerted on the doors in order to, for example, allow customers and employees to exit a building in the event of a fire. The system also includes a leveling system configured to keep at least one door level when it breaks out.

An inward-opening type casement window having outward-opening pane and screen is provided. A primary screen is installed, via a first hinge, in a primary casement window frame so as to open inwardly. The primary screen is formed with a secondary frame. A secondary pane is installed, via a second hinge, in the secondary frame so as to open outwardly. A handle lock is installed between the primary screen and the primary casement window frame and between the secondary pane and the secondary frame. The handle lock is used to control opening and closing of the primary screen and the secondary pane. The pane can be swung out to facilitate ventilation, and the screen can prevent entry of insects and burglars. Moreover, the pane can be swung in together with the screen, thereby facilitating access, ventilation and cleansing.
