A locking mechanism for a door panel to be positioned within and out of blocking relationship with an opening. Mechanism includes a deadbolt rotatably connected to the wall and having a curved configuration and a locking bracket connected to the door panel. The locking bracket extends from the door panel in an angular direction with respect to a plane of door panel. With door panel in a closed position and deadbolt in a first position, the locking bracket extends through the curved configuration. Deadbolt is in blocking relationship with the locking bracket in a direction along a plane of the door panel and is not in blocking relationship in a direction along the locking bracket. With door panel in closed position, deadbolt is in a second position not in blocking relationship with the locking bracket permitting door panel to move in a direction along a plane of the door panel.

This disclosure pertains to a pet door apparatus, and in particular, a pet door apparatus integrated within sliding glass door frames of apartment units and other enclosed building structures. A pet door apparatus consistent with the present disclosure comprises a plurality of panels which features a flap within one of the panels. The plurality of panels are coupled to each other by at least one attachment mechanism. The coupling between the first panel and the second panel and the coupling between the second panel and the third panel forms an assembled unit. The point of coupling between at least two of the panels is adjustable to extend the length of the assembled unit. An end of one of the panels is fitted within the first track of the slidable door frame. An end of one of the other panels is fitted within the second track of the slidable door frame.

A barrier employed to keep children and/or pets in or out of certain areas in the house. The barrier includes four panels. Two main panels slide parallel to each other to lengthen or shorten the barrier as a whole. Two side panels stabilize the main panels and extend to the front and rear faces of the main panels to provide a self-supporting in-house barrier. Each of the panels includes a wooden frame. The wood lends less weight, less sharp edges, and more pleasing aesthetics than, for example, a metal gate. Legs are connected to the side panels to further stabilize the side panels and main panels.
