Embodiments of the present invention relates to a window system that a solar panel provided in the project window is easily detachable, and more particularly, a project type window system according to present invention includes a window frame; a project frame with an upper end hinged to an upper end of the window frame configured to be opened and closed in a project type while moving away or close with respect to the window frame; a louver frame provided inside the project frame; and a solar panel including a solar cell and a photovoltaic frame to support the solar cell; wherein the louver frame includes a supporting plate with a tilt hole elongated in a height direction of the project frame, a panel holder for fixing and holding the solar panel inside of the supporting plate by including a tilt shaft on an opposite side to which the solar panel is held and inserting the tilt shaft into the tilt hole, and a socket for tiltably supporting the solar panel with respect to the louver frame from an outside of the supporting plate by being coupled to the tilt shaft, wherein the photovoltaic frame is slide-inserted through an opened one end of the panel holder, and is supported by the other end of the panel holder, and wherein the photovoltaic frame is coupled to the panel holder in the other end of the panel holder.

An overhead door frame assembly has a horizontal header connected to tripod legs with splice assemblies. Each tripod leg has two upright columns connected to an upright I-bar and a support assembly and the upright columns and the upright I-bar are secured to a base adapted to be secured to a floor of a building. One of the splice assemblies is fastened to each upright column. Hinges pivotally mount an overhead door to the header to allow hydraulic cylinders connected to the support assemblies to move the overhead door to an open position and a closed position.

A door assembly includes a frame having interconnected wires that define an opening for an animal to pass therethrough, and a door having interconnected wires and being coupled to the frame. A latch assembly has a handle structure and a pin. The handle structure is pivotable with respect to one of the door and the frame, and the pin is movable axially with respect to one of the door and the frame. A first wire of the plurality of wires of the frame forms a key hole assembly. The key hole assembly defines an aperture for receiving the pin when the door is in a latched position with respect to the frame. A tab assembly is formed by at least one wire of the door and is disposable behind at least one of the plurality of wires of the frame in the closed position.

The window assembly of the present invention includes a window frame and window sash rotatable relative to the window frame between a closed position and an open position. In the closed position, the window sash is positioned parallel to the window frame. In the open position, a space is defined between the bottom edges of the window frame and the window sash, and the space defined between the side edges of the window frame and the window sash. A window screen is connected to the two side edges and the bottom edge of the window sash, the two side edges and the bottom edge of the window frame. The window screen is configured to extend in the space. The viewer can have a clear view out of the window assembly without the unsightliness, distortion, or sunlight blockage that is caused by conventional “always visible” window screens.
